The main movement of a milling machine is the rotational movement of the milling cutter. On most milling machines (such as vertical lift milling machines), the feed movement is realized by the linear movement of the workpiece in the direction perpendicular to the axis of the milling cutter. Yes, on a few milling machines (such as horizontal lifting table milling machines), the feed motion is the rotary motion or curved motion of the workpiece. In order to adapt to the processing of workpieces of different shapes and sizes, the milling machine has adjustment movements in three mutually perpendicular directions, and can realize feed movement in any one of the directions according to the processing requirements. On a milling machine, the movement of feeding the workpiece and adjusting the relative position of the tool and the workpiece can be realized by the workpiece or by the tool and the workpiece respectively, depending on the type of machine tool. When operating the feed handle of the machine tool workbench, the direction pointed by the handle is the direction of the feed movement of the workbench, making it less likely to cause errors during operation. On the front and left side of the machine tool, there are a set of buttons and handles for the compound operator to operate at different positions. There is a double nut gap adjustment device on the longitudinal wire of the workbench, so it can be used for both reverse milling and down milling. The speed control relay is used for braking, which can quickly stop the spindle rotation. The working principle of a CNC milling machine: On the milling machine, the process, process parameters, and relative displacement of the tool and the workpiece are written into a processing program sheet in CNC language, and then the program is input into the CNC device, and the CNC device will follow the CNC Instructions control various operations of the machine tool and the relative displacement of the tool and the workpiece.

Winding machine is no stranger to motor manufacturers. It is an indispensable motor production equipment. It mainly winds the coils of motors. It is often used in various brushless motors, transformers, reactors, etc. It can be said that electromagnetic components are required The products of the coil part all need to use the winding machine. So what is the working principle of the winding machine? What are the common precautions? Before starting the machine, fix the iron core mold to be wound on the bracket, input the program, adjust various parameters, including wire diameter, number of turns, speed, slot crossing, forward rotation and reverse rotation, etc., and then automatically through the programmable controller The numerical value is calculated and displayed on the touch screen. Start the spindle motor, first wind 2 to 3 laps at a slow speed, and after making sure that there is no problem, slowly increase the speed to high speed until the winding is completed, the machine automatically clamps the wire, a complete winding process is completed, and then repeat this action . 1. Before using the winding machine, you should first confirm that the electricity and compressed air are in place, and you can run the winding machine after manual reset. 2. When the winding machine is running, the staff must not put their hands into the area between the skeleton trough and the feeding tooling to avoid hurting their hands. 3. The placement of the mold must be accurate, and it must be checked first. In many cases, the mold is not installed properly, and the nozzle is easy to be damaged. If the mold is not placed properly, you should press the pause button to ensure that the installation is correct before starting. 4. If the thread is broken during the winding process, you should immediately press the pause button. Generally speaking, it may be that the thread barrel is stuck, the tensioner is not set properly, or the speed is too fast. After checking, you should wind the thread slowly to ensure Speed up no problem. 5. In the event of a power failure or an emergency, be sure to reset and clamp the wire again before restarting. 6. When the thread is almost used up, tie the new thread with the old thread and pull it to the guide pin before starting. Before changing the thread, touch the upper edge of the thread barrel with your hands to see if there are burrs or foreign objects, so as to avoid interfering with the normal state of the thread. operation, causing a disconnection to occur.

A pump is a machine that transports or pressurizes a liquid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali, emulsion, suspoemulsion and liquid metal. Liquids, gas mixtures and liquids containing suspended solids can also be transported. The technical parameters of pump performance include flow rate, suction lift, lift, shaft power, water power, efficiency, etc.; according to different working principles, it can be divided into volumetric pumps, vane pumps and other types. Positive displacement pumps use the change in the volume of their working chambers to transfer energy; vane pumps use the interaction between rotating blades and water to transfer energy, and there are centrifugal pumps, axial flow pumps and mixed flow pumps. centrifugal pump 1. Working principle of centrifugal pump Before starting the water pump, first fill the pump and the water inlet pipe with water. After the water pump is running, under the action of the centrifugal force generated by the high-speed rotation of the impeller, the water in the impeller channel is thrown to the surroundings and pressed into the volute, forming a vacuum at the impeller inlet. The water in the pool is sucked along the suction pipe under the external atmospheric pressure to supplement this space. Then the inhaled water is thrown out by the impeller through the volute and enters the outlet pipe. It can be seen that if the impeller of the centrifugal pump rotates continuously, it can continuously absorb and press water, and the water can be continuously lifted from a low place to a high place or far away. To sum up, the centrifugal pump is called a centrifugal pump because it lifts water to a high place under the action of the centrifugal force generated by the high-speed rotation of the impeller. 2. General characteristics of centrifugal pumps (1) The flow direction of water along the centrifugal pump is sucked in along the axial direction of the impeller, and flows out perpendicular to the axial direction, that is, the direction of water flow in and out is 90° to each other. (2) Since the centrifugal pump relies on the inlet of the impeller to form a vacuum to absorb water, it is necessary to pour water into the pump and the suction pipe before starting, or use a vacuum pump to exhaust the air to form a vacuum, and the pump casing and the suction pipe must be strictly sealed. There must be no air leakage, otherwise a vacuum will not be formed and water will not be absorbed. (3) Since the impeller inlet cannot form an absolute vacuum, the suction height of the centrifugal pump cannot exceed 10 meters. In addition to the loss along the process caused by the water flowing through the suction pipeline, the actual allowable installation height (the height of the pump axis to the suction water surface) is much less than 10 m. If the installati...

1. The basic composition of CNC milling machine. The most basic composition of CNC milling machine includes six parts: I/O device, CNC device, servo drive device, measurement feedback device, auxiliary device, and machine tool body. The six parts will be introduced in detail below. (1) I/O device. The I/O device is used for the input/output of data such as CNC machining or motion control programs, machining and control data, machine tool parameters, coordinate axis positions, and detection switch states. Keyboard and monitor are necessary and most basic I/O devices for CNC equipment. As the peripheral equipment of the numerical control system, the desktop computer and the portable computer are one of the commonly used I/O devices at present. (2) Numerical control device. The numerical control device is the core of the numerical control system, which is composed of I/O interface lines, controllers, arithmetic units and memory. The function of the numerical control device is to compile, calculate and process the data input by the input device through the internal logic circuit or control software, and output various information and instructions to control the various parts of the machine tool to perform specified actions. Among these control information and instructions, the most basic ones are the coordinate axis feed speed, feed direction, and feed displacement instructions generated after interpolation operations, and are provided to the servo drive device. After being amplified by the driver, the final control Axis displacement. These control information and instructions directly determine the movement trajectory of the tool or coordinate axis. 3) Servo drive. Servo drives are usually composed of servo amplifiers (also known as drives, servo units) and actuators. In CNC machine tools, AC servo motors are generally used as actuators. At present, linear motors have been used in advanced high-speed processing machine tools. In addition, among the CNC machine tools produced in the 20th century, there are also simple CNC machine tools using DC servo motors, and stepping motors are also used as actuators. Servo amplifier It must be used in conjunction with the drive motor. (4) Measuring feedback device. The measurement feedback device is the detection link of the closed-loop (semi-closed-loop) CNC machine tool. Its function is to convert the actuator to Or the actual speed and displacement of the workbench are detected, and fed back to the servo drive device or numerical control device to compensate the feed speed or the motion error of the actuator, so as to achieve the purpose of improving the accuracy of the motion mechanism. The position of the measuring device detection signal feedback depends on the structure of the numerical control system. Servo built-in pulse encoders, tachometers and linear gratings are commonly used detection components. The advanced servo drive device adopts digital servo drive technology (referred to as digital servo), a...
