Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing tools, and in particular to a tool for testing the mounting position of bearing housings and motors. Background Technology
[0002] Existing bearing housing inspection fixtures can only check the parallelism between the motor housing and the component mounting surface by fitting the bearing into the bearing position; existing calibration fixtures cannot check the condition of the incoming bearing housing and can only rely on processing to ensure it; existing fixtures can only check the parallelism between the bearing housing and the mounting surface, but cannot check the perpendicularity and coaxiality between the bearing and the motor end; checking the position of the motor mounting surface and the bearing requires installing a lead screw and then using the lead screw for marking and calibration, which requires disassembly and reassembly, and the process is cumbersome.
[0003] In view of the above, it is necessary to improve the existing bearing housing inspection fixtures to meet the current needs of bearing housing inspection. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a tool for detecting the installation position of a bearing housing and a motor, including a calibration bar, an angular contact bearing disposed on the outside of the calibration bar, a spacer ring disposed on the calibration bar, a bearing cap disposed on the outside of the spacer ring and located on one side of the angular contact bearing, a precision nut disposed on the calibration bar and located on one side of the spacer ring, a dial indicator mounting base disposed on the calibration bar, and a bearing housing disposed on the bearing cap and the outside of the angular contact bearing, wherein the bearing housing is fixedly installed on the component mounting surface.
[0005] As a further addition to this technical solution, the spacer ring rests against one side of the angular contact bearing.
[0006] As a further addition to this technical solution, the precision nut is fitted onto the calibration bar and locked in place so that the spacer ring presses against the angular contact bearing.
[0007] As a further supplement to this technical solution, before starting work, a dial indicator should be used to check the parallelism between the bearing housing and the component mounting surface.
[0008] Its beneficial effects include the ability to inspect the bearing housing machining condition before assembly; improved assembly processability; saved assembly time; simplified installation; and facilitated installation operations. Attached Figure Description

[0013] To facilitate a clearer understanding of this technical solution for those skilled in the art, the following will be described in conjunction with the appendix. Figure 1 -3. A detailed description of the technical solution of this utility model:
[0014] A tool for detecting the mounting position accuracy of a bearing housing and a motor includes a calibration bar 1, an angular contact bearing 3 disposed on the outside of the calibration bar 1, a spacer ring 5 disposed on the calibration bar 1, a bearing cap 4 disposed on the outside of the spacer ring 5 and located on one side of the angular contact bearing 3, a precision nut 6 disposed on the calibration bar 1 and located on one side of the spacer ring 5, a dial indicator mounting base 7 disposed on the calibration bar 1, and a bearing housing 2 disposed on the outside of the bearing cap 4 and the angular contact bearing 3, wherein the bearing housing 2 is fixedly mounted on the component mounting surface.
[0015] Among them, the spacer ring 5 rests against one side of the angular contact bearing 3.
[0016] Among them, the precision nut 6 is fitted onto the calibration bar 1 and locked so that the spacer ring 5 presses against the angular contact bearing 3.
[0017] Before starting work, a dial indicator is used to check the parallelism between the bearing housing 2 and the component mounting surface.
[0018] The overall working principle of this utility model will be explained in the following system: First, fix the bearing housing 2 on the component mounting surface, put the angular contact bearing 3 into the calibration bar 1, then put in the spacer ring 5, and then tighten the precision nut 6 to make the spacer ring 5 press the angular contact bearing 3; put the above-mentioned calibration bar 1 into the installed bearing housing 2; finally, use the bearing cover 4 to press the outer ring of the bearing; before working, first set up a dial indicator to check the parallelism between the bearing housing 2 and the component mounting surface; after the above is completed, install the dial indicator fixing seat 7 on the calibration bar 1, and install the dial indicator on the dial indicator fixing seat 7 to facilitate subsequent inspection of the perpendicularity and coaxiality between the motor and the bearing.
