Importance of transformer automatic winding machine thimble

The winding machine has different component configurations due to the different winding coils. At present, many winding machines have a thimble device. The structure and principle of the winding machine are the same as those of the lathe. In practice, many customers do not use the ejector pin. The role of the device, even the unauthorized removal of this part, these practices are wrong, will affect the winding quality of the equipment, the situation will accelerate the equipment wear and equipment damage. The ejector device plays the concentricity of the main shaft and the winding mandrel in the winding machine and bears the load force from the radial direction, reduces the load on the main shaft, reduces the radial runout during the operation of the machine, and makes the main shaft run. More stable and smooth.

  In the transformer winding machine, the role of the ejector device is mainly to bear the radial load of the main shaft. The coils wound by the transformer winding machine are generally heavy, so the thimble device is more rigid than the automatic winding machine, and the thimble is generally divided into manual Both the type and the electric type, the structure and principle of the manual type thimble are basically the same as those of the large lathe thimble. The position of the thimble is moved by the rotation of the swaying disc. The electric ejector pin drives the movement between the gear and the rack by the slow motor. The position movement of the ejector device is realized. When the pitch is adjusted, the manual ejector pin can not be rotated as the standard, and the electric thimble is supported by the top force. After the pitch adjustment, the winding shaft can be forced to check whether the spacing is reasonable. The thimble device is one of the important components of the winding machine. It is related to the winding effect and the safety of the equipment. Therefore, the operator must pay attention to the adjustment and reasonable use of the thimble device.

  In the automatic winding machine, the ejector device is an indispensable component, which directly affects the cable effect of the device. The ejector device can maintain the relative concentricity between the winding mandrel and the main shaft while reducing the radial runout to obtain the best. The ejector device of the automatic winding machine is generally divided into two types of manual type and pneumatic type. The manual type requires the operator to move the moving rod to realize the action of the thimble. The pneumatic thimble needs an external air source as the power, and the device is provided with The pitch adjustment function needs to adjust the spacing when using mandrels of different lengths. The adjustment of the manual thimbles realizes the distance between the thimble and the winding main shaft by moving the fixed position. The adjustment of the pneumatic thimble requires not only the adjustment of the fixed position but also the adjustment of the cylinder liter. Shrinking distance and speed, the over-tightening of the thimble device will bend the mandrel and increase the load on the spindle motor. If it is too loose, the device will not function. It should be adjusted according to the length of the mandrel.
