Description

Technical Field

[0001] This application relates to the technical field of motors, specifically a rotor bearing disassembly tooling. Background Art

[0002] The rotor is a key component in a motor. It is usually a cylindrical or disc-shaped component that can rotate around the central axis. To support and ensure the rotation of the rotor, bearings are usually used to install the rotor inside the motor.

[0003] After the rotor works for a long time, the bearing may fail due to wear, looseness, dust ingress, etc. Therefore, it needs to be disassembled for maintenance or replacement.

[0004] For example, the patent with the publication number CN206575309U specifically discloses a motor rotor bearing disassembly tooling. This tooling places the rotor on the support seat, makes the rotor shaft located in the notch, and the bearing baffle separates the bearing and the iron core of the motor rotor. Subsequently, the cylinder pushes the ejector rod to eject the rotor shaft, so that the bearing and the rotor are separated.

[0005] However, during the process of disassembling the bearing in the above patent, there is no component for removing rust at the connection between the bearing and the rotor shaft. In this way, when facing some rotors that are rusty after long-term use (such as rust at the connection between the rotor and the rotor shaft), only forced disassembly can be carried out, which is extremely likely to cause scratches, deformation or cracking on the surfaces of the bearing and the rotor shaft during disassembly, thus affecting their performance and service life.

[0006] Therefore, it is necessary to provide a rotor bearing disassembly tooling to solve the above problems.

[0007] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of this application, and therefore, it may include information that does not constitute the prior art. Summary of the Invention

[0026] As Figure 1 - Figure 2 shown, this application provides a rotor bearing disassembly tooling, including a body 1, and a rotating component 5 is fixedly installed on the body 1, and the rotating component 5 is used to rotate the workpiece;

[0027] As Figure 2 - Figure 3 shown, the rotating component 5 includes a base 53 fixedly installed on the body 1, a round groove 57 is opened on the base 53, a round pipe 55 is rotatably installed inside the round groove 57, a cavity (not shown in the figure) is opened inside the base 53, the cavity is communicated with the round groove 57, a worm gear 56 is arranged inside the cavity, and the worm gear 56 is fixedly sleeved on the round pipe 55, a worm 54 is rotatably installed inside the base 53, the worm 54 is located inside the cavity, the worm 54 and the worm gear 56 are meshed and connected, and a handle 51 is fixedly installed at one end of the worm 54 away from the base 53;

[0028] Meanwhile, a turntable 52 is fixedly installed at the top of the circular tube 55, and through holes 58 are provided through the turntable 52 and the base 53 to facilitate the rotor shaft and bearing on the rotor to pass through;

[0029] Rotate the handle 51 to drive the worm 54 to rotate, thereby driving the worm gear 56 to rotate, synchronously driving the circular tube 55 to rotate, and the circular tube 55 drives the turntable 52 to rotate;

[0030] Meanwhile, a clamping assembly 4 is fixedly installed on the rotating assembly 5, and the clamping assembly 4 is used to clamp the rotor;

[0031] As Figure 1 - Figure 2 shown, the clamping assembly 4 includes a clamping part 41 fixedly installed on the turntable 52. The clamping part 41 is an existing pneumatic finger, and its specific structure and principle will not be elaborated here. Meanwhile, two groups of connecting blocks 42 are fixedly installed on the clamping part 41, and a clamping block 43 is fixedly installed at the end of the connecting block 42 away from the clamping part 41;

[0032] After one end of the rotor with a bearing passes through the through hole 58 on the rotating assembly 5, under the drive of the clamping part 41, the clamping block 43 clamps the bearing to fix the bearing;

[0033] Meanwhile, a stamping assembly 2 is fixedly installed on the machine body 1, and the stamping assembly 2 is used to separate the bearing and the rotor shaft;

[0034] As Figure 1 shown, the stamping assembly 2 includes a cylinder 21 fixedly installed on the machine body 1. Meanwhile, a push rod 22 is fixedly installed at the output end of the cylinder 21, and a punch 23 is fixedly installed at the end of the push rod 22 away from the cylinder 21. It should be noted that a buffer pad (not marked in the figure) is provided on the machine body 1, and the buffer pad is located below the rotating assembly 5 to buffer the rotor that falls off after disassembly and prevent it from being damaged;

[0035] Driven by the cylinder 21, the push rod 22 drives the punch to move downward until it contacts the rotor shaft on the rotor and continues to push downward. At this time, due to the action of the clamping assembly 4, the bearing does not move, and the punch 23 mechanically presses down to separate the bearing and the rotor shaft;

[0036] Meanwhile, a rust removal assembly 3 is fixedly installed on the machine body 1, and the rust removal assembly 3 is used for rust removal operations on the bearing and the rotor shaft;

[0037] As Figure 1 - Figure 2As shown in the figure, the rust removal component 3 includes a storage tank 31 fixedly installed on the machine body 1. The interior of the storage tank 31 is provided with rust remover. At the same time, a water pump 32 is fixedly installed on the machine body 1. The input end of the water pump 32 and the liquid outlet of the storage tank 31 are connected by a pipeline. At the same time, a spray pipe 33 is detachably arranged on the machine body 1, and a plurality of spray holes are arranged at one end of the spray pipe 33 far away from the machine body 1 to facilitate the spraying of rust remover;

[0038] At the same time, a liquid inlet 34 is arranged on the spray pipe 33, and the liquid inlet 34 and the output end of the water pump 32 are connected by a hose;

[0039] When rust is present at the connection between the bearing and the rotor shaft, adjust the spray pipe 33 to the connection between the bearing and the rotor shaft after being clamped by the clamping component 4. Driven by the water pump 32, the rust remover is introduced into the spray pipe 33 to spray and remove rust at the connection between the bearing and the rotor shaft. At the same time, rotate the rotating component 5 to drive the clamping component 4 to rotate, thereby synchronously driving the workpiece to rotate, and the rotation speed is slow through the cooperation of the worm gear 56 and the worm 54 for uniform spraying. After standing for a period of time, it can be disassembled by the stamping component 2;

[0040] It should be noted that in the case of rust on both sides, the above process can be used to clean one side. Then remove the rotor, turn over the cleaned side of the bearing, and then directly fix the bearing with the clamping component 4 without passing through the rotating component 5 to remove rust on the other side;

[0041] In summary, when disassembling the bearing, pass the bearing and the rotor shaft through the rotating component 5 and clamp and fix them with the clamping component 4, and the stamping component 2 can be used to perform stamping separation. When rust appears at the connection between the bearing and the rotor shaft, after performing rust removal operation on it through the rust removal component 3, then use the stamping component 2 for stamping separation.

[0042] The above is only the preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
