Description

Technical Field

[0001] The utility model relates to the technical field of disassembly devices, in particular to a mechanical end cover disassembly device. Background Art

[0002] The end cover is a rear cover installed behind the casing of the motor, commonly known as the "end cover". There are many types of end covers. The end cover is mainly composed of a cover body, bearings and brushes. The quality of the end cover will directly affect the quality of the motor.

[0003] In the prior art, a Chinese patent with publication number CN211681871U proposes a mechanical end cover disassembly device, which directly clamps the end cover and then presses or directly disassembles it, thereby avoiding the mechanical end cover disassembly device from causing damage to the end cover or causing the end cover to deform. However, in actual application, there are still mechanical end covers of different shapes. When the connecting bolts on the end cover are directly disassembled, the shape of the end cover may change, thereby causing the position of the bearing to change, causing damage to the motor. Therefore, we disclose a mechanical end cover disassembly device. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a mechanical end cover disassembly device to solve the problem that the change of the shape of the end cover affects the change of the bearing position and damages the motor.

[0005] Based on the above-mentioned purpose, the utility model provides a mechanical end cover disassembly device, including a fixed column, the middle part of the fixed column is rotatably connected with four limit rings, one end of the limit ring is fixedly connected with a connecting block, one end of the connecting block is provided with a limit assembly, and the limit assembly can limit the position of the end cover before and after disassembly, the limit assembly is connected to the connecting block, and the limit assembly includes a connecting cylinder fixedly connected to the connecting block, one end of the connecting cylinder is movably sleeved with a first limit rod, a first spring fixedly connected to one end of the first limit rod is fixedly connected to the connecting block, the first spring is located in the connecting cylinder, the first limit rod is L-shaped, and a limit groove is provided on the outer wall of the lower end of the first limit rod, a rotating sleeve is rotatably connected in the limit groove, one end of the rotating sleeve is fixedly connected to a plurality of limit columns, and the middle part of the limit column is slidably connected with a clamping plate.

[0006] Preferably, a telescopic slot is formed at one end of the first limiting rod, the telescopic slot is fixedly connected to the second limiting rod via a second spring, and the second limiting rod is L-shaped.

[0007] Preferably, the outer wall of the rotating sleeve is provided with a plurality of anti-slip grooves.

[0008] Preferably, the outer wall diameter of the limiting groove is equal to the outer wall diameter of the first limiting rod, and the clamping plate is a U-shaped plate.

[0009] The beneficial effects of the utility model are as follows: the fixed column limits the moving position of the connecting block through the limiting ring, thereby limiting the position of the limiting assembly, so that the limiting assembly can rotate around the fixed column, and the limiting assembly is moved to a position suitable for fixing the end cover, so that the device can be applicable to end covers of various sizes, ensuring that the position of the end cover is fixed by the limiting assembly, improving the practicality of the device, and limiting the position of the end cover and the machine itself through the first limiting rod through the telescopic groove, so that the device helps to limit the relative position of the end cover and the machine, so that the end cover will not be deformed during the process of sequentially disassembling the bolts connecting the end cover and the machine, thereby avoiding the situation where the position of the bearing changes and damages the motor;

[0010] After all the connecting bolts between the end cover and the machine are removed, turn the second limit rod until it is no longer connected to the machine, then turn the clamping plate to the connection between the end cover and the machine, and then lift the fixed column so that the fixed column drives the clamping plate to move through the connecting tube and the first limit rod, so that the clamping plate drives the entire end cover to be lifted directly, thereby reducing the possibility of deformation during the disassembly of the end cover, thereby facilitating the disassembly of the end cover.
