DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-3 As shown, a device for detecting the wall thickness of a bearing ring 7 comprises a detection platform 1, on which a pulling roller 2, a positioning roller 3 and a detection roller 4 are provided which cooperate with the inner wall of the bearing ring 7 and cooperate with the outer wall of the bearing ring 7. The pulling roller 2, the positioning roller 3 and the detection roller 4 are located in a straight line, and the positioning roller 3 is located between the pulling roller 2 and the detection roller 4. The pulling roller 2 and the detection roller 4 are slidably matched with the detection platform 1, and the inner wall of the bearing ring 7 is pressed against the positioning roller 3. The pulling roller 2 is used to pull and tighten the bearing ring 7, so that the bearing ring 7 can only rotate but cannot slide on the detection platform 1; the detection roller 4 and the positioning roller 3 clamp the side wall of the bearing ring 7, and the detection roller 4 and the detection roller 4 are slidably matched with the detection platform 1. The inner wall of the bearing ring 7 is pressed against the positioning roller 3, and the bearing ring 7 is tensioned and fixed by pulling by the pulling roller 2, so that the bearing ring 7 can only rotate but cannot slide on the detection platform 1; the detection roller 4 and the positioning roller 3 clamp the side wall of the bearing ring 7, and the detection roller 4 and the detection roller 4 are slidably matched with the detection platform 1. 4 is pressed against the outer side of the bearing ring 7, and the bearing ring 7 is rotated manually. When the thickness of the bearing ring 7 changes, the detection roller 4 will slide. A scale 5 is inlaid on the upper end of the detection table 1. The upper end surface of the scale 5 is flush with the upper end surface of the detection table 1, which does not affect the horizontal placement of the bearing ring 7. The "0" scale line of the scale 5 is flush with the side wall of the positioning roller 3 facing the detection roller 4. A pointer 402 that slides with the scale 5 is connected to one side of the detection roller 4. The scale indicated by the pointer 402 is the thickness of the bearing ring 7. When the pointer 402 slides, it indicates that the thickness of the bearing ring 7 changes, that is, the thickness of the bearing ring 7 is uneven and the product is unqualified.

[0024] like Figure 4-5As shown, a sliding hole 105 is provided at one end of the detection platform 1, a limiting hole 101 connected to the sliding hole 105 is provided at the upper end of the detection platform 1, the pulling roller 2 cooperates with the limiting hole 101, and the lower end of the pulling roller 2 is connected with a first push rod 201 cooperating with the sliding hole 105. A first handle 202 is provided at the end of the first push rod 201 away from the pulling roller 2, and a first spring 6 is provided between the first handle 202 and the detection platform 1. The first spring 6 is sleeved on the first push rod 201. When installing the bearing ring 7, it is necessary to push the first handle 202 to reduce the distance between the pulling roller 2 and the positioning roller 3. After the bearing ring 7 is sleeved on the outside of the pulling roller 2 and the positioning roller 3, the first handle 202 is released. Under the action of the first spring 6, the pulling roller 2 tightens the bearing ring 7 to press the inner wall of the bearing ring 7 onto the positioning roller 3.

[0025] A support block 104 is provided at the upper end of the detection table 1, and a support frame 401 is sleeved on the outer side of the detection roller 4. The support frame 401 is connected with a guide rod 406 and a second push rod 404 that penetrates the support block 104. A second spring 405 is provided between the support frame 401 and the support block 104. The second spring 405 is sleeved on the outer side of the second push rod 404. A second handle 403 is provided at the end of the second push rod 404 away from the support frame 401, and the detection roller 4 can be pulled by the second handle 403.

[0026] The pointer 402 is connected to the support frame 401 , and the pointer 402 is closely attached to the upper end surface of the scale 5 .

[0027] For ease of use, the second handle 403 is rotatably connected to the second push rod 404 through a bushing, and a shift lever cooperating with the second handle 403 is provided at the upper end of the support platform. The second handle 403 is pulled and rotated so that the second handle 403 is located on one side of the shift lever 102. The shift lever 102 can block the second handle 403 to prevent the detection roller 4 from resetting, thereby facilitating the taking and placing of the bearing.

[0028] A retaining groove 103 cooperating with the second handle 403 is provided on the side wall of the retaining rod 102. The retaining groove 103 can prevent the second handle 403 from slipping off, thereby ensuring the reliability of use.

[0029] When in use, pull the second handle 403 to cooperate with the blocking rod 102 to open the detection roller 4, push the first handle 202, install the bearing ring 7, loosen the first handle 202, let the pulling roller 2 tighten the bearing ring 7 to position, rotate the second handle 403, let the detection roller 4 press against the outer wall of the bearing ring 7, rotate the bearing ring 7, and observe whether the reading of the pointer 402 is within the allowable error range. If the pointer 402 is within the allowable error range, the inspection is qualified, otherwise, the product is unqualified.
