Bearing dismounting device used in fan maintenance process

Abstract

The invention discloses a bearing dismounting device used in a fan maintenance process. The device comprises a barrel body, a sliding block is slidably arranged in a second through groove in an attached mode, the section of the sliding block is in a right triangle shape, the top end of the sliding block penetrates out of the second through groove, the bottom face of the sliding block is fixedly connected with the top face of a second dovetail block, and the side wall of a vertical rod of a T-shaped sliding rod is fixedly connected with a third spring. One end of the third spring is fixedly connected with the side wall of the barrel body, the model of a PLC is CPM1A-10CDR-A-V1, the barrel body and an annular barrel body are connected in a welded mode, a first barrel body is made of alloy steel materials, fan bearings with different inner diameters can be accurately hooked, and meanwhile, signals can be transmitted to workers in time. The device is convenient to operate by workers, capable of indirectly supporting multiple clamping blocks and ensuring that the multiple clamping blocks apply uniform force to the bearings, so that it is ensured that the bearings are pulled out while being uniformly stressed, the integrity of the bearings is ensured, the operation is easy, the working efficiency is improved, and the use requirement is met.

Description

technical field [0001] The invention relates to the technical field of fan maintenance, in particular to a bearing removal device used in the fan maintenance process. Background technique [0002] The bearing disassembly link is an important link in the maintenance process of the fan. When disassembling, attention should be paid to maintaining the original appearance of the bearing to ensure the safety of the dismantling workers and improve the efficiency of disassembly. The commonly used bearing disassembly method is the pull-out method. The pull-out method is Use a special tool to hook the inner ring of the bearing, it is easy to cause the pull-out direction to deviate or the pull-out force is too large when pulling out the bearing, and it is not easy to take out the bearing while the bearing is stuck, and it is easy to damage the bearing; and the bearing disassembly method In actual use, there is a high probability of bearing damage. The staff cannot accurately know wheth...

Problems solved by technology

[0002]The bearing disassembly link is an important link in the maintenance process of the fan. During disassembly, care should be taken to maintain the original appearance of the bearing to ensure the safety of the dismantling workers and improve the disassembly efficiency. Commonly used bearing disassembly methods include the pulling method. The pulling method is to hook the inner ring of the bearing with a special tool. It is not convenient to take out the bearing, and it is easy to damage the bearing; and the bearing removal method has a high probability of causing bearing damage in actual use, and the staff cannot accurately know whether the hook is hooked on the bearing. Hooking the bearings wastes time and reduces work efficiency, which also leads to high difficulty in specific operations and is difficult to meet the requirements of non-destructive bearings and quick and easy disassembly
