Description

Technical Field

[0001] The utility model relates to the technical field of centering shafts, in particular to a follow-rotating centering shaft for lapping the inner groove of a deep groove ball bearing. Background Art

[0002] After the raceway on the bearing inner ring is machined, it needs to be fine-ground to meet the requirements of use. The common method is to fit the bearing inner ring onto the centering shaft support device and then clamp it on the machine tool for processing.

[0003] The matching relationship between the bearing and the centering shaft is: the bearing sleeve is on the outside of the centering shaft. This matching method will cause wear on the fitting surface of the support seat and the centering shaft after long-term work. The transmission centering shaft is an integrated structure, so once it is worn, the entire centering shaft will be replaced, wasting resources. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] To this end, the technical solution adopted in this utility model is:

[0006] A follow-rotating centering shaft for lapping the inner groove of a deep groove ball bearing includes a supporting mechanism and a protecting mechanism. The supporting mechanism includes a supporting seat, a supporting shaft rotationally connected to the supporting seat, and a protecting mechanism. The protecting mechanism includes a wear-resistant plate movably sleeved on the outer side of the supporting shaft, two clamping blocks embedded on both sides of the wear-resistant plate and connected to the supporting seat, and two plug-in shafts plugged into the clamping blocks, wherein the inner ends of the plug-in shafts extend into the interior of the wear-resistant plate.

[0007] By adopting the above technical solution, once the wear-resistant sheet is severely worn, the staff can pull out the plug shaft to free the wear-resistant sheet from restraint, and then move the wear-resistant sheet outward along the support shaft to replace it, and then repeat the above steps from bottom to top to complete the installation of the new wear-resistant sheet. Similarly, when the outer wall of the support shaft is worn, the support shaft can be directly unscrewed, and the support shaft and wear-resistant sheet that fit the bearing can be flexibly replaced, effectively preventing waste of resources.

[0008] In a preferred example, the present invention can be further configured as follows: a slide groove is provided on the top of the support shaft, and the slide groove is located outside the wear-resistant plate.

[0009] In a preferred example, the present invention can be further configured as follows: a limiting mechanism is provided inside the slide groove, and the limiting mechanism includes a flat pin slidably arranged inside the slide groove, and a rubber column connected to the front end of the flat pin, and the front end of the rubber column passes through the slide groove and extends to the inner wall of the support shaft.

[0010] In a preferred example, the present invention can be further configured as follows: the top of the flat pin is composed of a plane and an inclined surface, and the inclined surface is located between the plane and the rubber column.

[0011] In a preferred example, the present invention can be further configured as follows: slots are provided on both sides of the wear-resistant plate, and the outer wall of the clamping block fits in contact with the inner wall of the slot.

[0012] In a preferred example, the present invention can be further configured as follows: one side of the clamping block is provided with an arc surface, and the insertion shaft is provided with an L shape.

[0013] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0014] 1.

Similarly, when the outer wall of the support shaft is worn, the support shaft can be directly unscrewed, and the support shaft and wear-resistant sheet that fit the bearing can be flexibly replaced, effectively preventing waste of resources.

[0015] 2. In the utility model, after the bearing is sleeved on the outside of the support shaft, the flat pin is moved along the slide groove to insert the flat pin into the bearing.

[0026] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0027] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0028] The following describes, in conjunction with the accompanying drawings, a follow-rotating centering shaft for lapping the inner groove of a deep groove ball bearing provided by some embodiments of the present invention.

[0029] Example 1:

[0030] Combine Figure 1-5 As shown, the utility model provides a follow-rotating centering shaft for lapping the inner groove of a deep groove ball bearing, comprising a support mechanism 100 and a protection mechanism 200. The support mechanism 100 comprises a support seat 110 and a support shaft 120 that is rotationally connected to the support seat 110.

[0031] The protection mechanism 200 includes a wear-resistant plate 210 movably sleeved on the outside of the support shaft 120, two clamping blocks 220 embedded on both sides of the wear-resistant plate 210 and connected to the support seat 110, and two plug-in shafts 230 plugged into the clamping blocks 220, and the inner ends of the plug-in shafts 230 extend into the interior of the wear-resistant plate 210.

[0032] Furthermore, notches are provided on both sides of the wear-resistant sheet 210 , and the outer wall of the clamping block 220 fits with the inner wall of the notch. The notches provide conditions for the wear-resistant sheet 210 to be sleeved on the two clamping blocks 220 .

[0033] Example 2:

[0034] Combine Figure 1 and Figure 3 As shown, based on the first embodiment, a slide groove is provided on the top of the support shaft 120 , and the slide groove is located outside the wear-resistant plate 210 . The slide groove is provided to provide conditions for installing the limiting mechanism 300 .

[0035] Furthermore, a limiting mechanism 300 is provided inside the slide groove, and the limiting mechanism 300 includes a flat pin 310 slidably arranged inside the slide groove, and a rubber column 320 connected to the front end of the flat pin 310. The front end of the rubber column 320 passes through the slide groove and extends to the inner wall of the support shaft 120. When the bearing sleeve is on the outside of the support shaft 120, the flat pin 310 is moved along the slide groove so that the flat pin 310 is inserted into the bearing. Then, the elasticity of the rubber column 320 enables the flat pin 310 to be firmly pressed against the flat pin 310.

[0036] Furthermore, the top of the flat pin 310 is composed of a plane and an inclined surface, and the inclined surface is located between the plane and the rubber column 320. This shape design ensures that the flat pin 310 can clamp the bearing outside the support shaft 120.

[0037] Example 3:

[0038] Combine Figure 1 、 3 and Figure 4 As shown, in the above embodiment, the block 220 is provided with an arc surface 400 on one side, and the plug shaft 230 is provided in an L shape. This shape design makes it convenient for the staff to insert and remove the plug shaft 230.

[0039] The working principle and usage process of the present invention are as follows: when the present device is put into actual use, the bearing sleeve is placed on the outside of the support shaft 120 and then fits with the wear-resistant sheet 210. During this process, once the wear-resistant sheet 210 is severely worn, the staff can pull out the plug shaft 230 to free the wear-resistant sheet 210 from its restraint, and then move the wear-resistant sheet 210 outward along the support shaft 120 to replace it, and then repeat the above steps from bottom to top to complete the installation of the new wear-resistant sheet 210. Similarly, when the outer wall of the support shaft 120 is worn, the support shaft 120 can be directly unscrewed, and the support shaft 120 and the wear-resistant sheet 210 that fit the bearing can be flexibly replaced, effectively preventing waste of resources.

[0040] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
