Description

Technical Field

[0001] This utility model relates to the field of bearing ring testing technology, specifically a bearing ring accuracy testing device. Background Technology

[0002] During the bearing manufacturing process, it is necessary to test the parallelism of the bearing end faces to ensure the manufacturing accuracy of the bearing. The existing testing method is to place the bearing race on the testing platform, then place the side wall of the bearing race against the positioning rod, and place the probe of the dial indicator against the end face of the bearing race from above. Then, the bearing race is rotated by hand. Although the testing speed is relatively fast, the test error is large due to the direct rotation of the bearing race by hand. Moreover, if there are debris or sand particles on the testing platform, it will not only affect the testing accuracy, but also wear down the bearing race.

[0003] Referring to Chinese Patent No. CN213238746U, which discloses a bearing ring end face parallelism testing device, this device solves the problem of large measurement errors caused by manual rotation of bearing rings. It can avoid the problems of easy wear when rotating on the testing table and the impact of debris between the testing table and the bearing ring on the testing accuracy, thereby improving the testing accuracy and safety.

[0004] A bearing race has two end faces, so two end face inspections are required. When the bearing race is fixed and clamped for inspection using the above-mentioned device, after one end face is inspected, the other end face cannot be inspected continuously. The bearing race needs to be removed, reversed, and re-clamped and assembled before the inspection of the other end face can continue. This is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0005] The purpose of this invention is to provide a bearing ring accuracy testing device, which effectively solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] A bearing ring accuracy testing device includes a base, a translation mechanism on one side of the base, and a testing structure on the other side for testing the parallelism of the bearing ring end faces. A driving mechanism is located above the translation mechanism, a reversing mechanism is located on the side of the driving mechanism, and a clamping mechanism is located below the reversing mechanism. The clamping mechanism is used to clamp and fix the bearing ring to be tested. The reversing mechanism is used to drive the bearing ring to rotate and adjust, thereby switching the testing end faces. The driving mechanism is used to drive the bearing ring to rotate and adjust, thereby achieving full-circumference testing of the bearing ring end faces. The translation mechanism is used to drive the bearing ring to feed towards the testing structure or to retract away from the testing structure.

[0008] Therefore, by setting the clamping mechanism on the reversing mechanism, after the parallelism test of one end face of the bearing ring is completed, the bearing ring can be rotated half a turn by the operation of the reversing mechanism. This allows the other end face of the bearing ring to be adjusted to face the testing structure. There is no need to remove the bearing ring, reverse the direction, and then re-clamp it. This allows for parallelism testing of both end faces, ensuring high continuity of the testing process, saving time and effort, and improving testing efficiency.

[0009] Furthermore, the translation mechanism includes a mounting base fixed on one side above the base, a power guide rail mounted above the mounting base, a movable seat mounted on the power guide rail, and a mounting platform fixed on top of the movable seat. The movable seat can be adjusted and translated along the power guide rail, and the drive mechanism is arranged above the mounting platform.

[0010] Furthermore, the drive mechanism includes a vertical plate, a first drive motor, and a mounting plate. The vertical plate is fixed vertically above the mounting platform, the first drive motor is fixed on the vertical plate, the mounting plate is fixed on the output shaft end of the first drive motor, and the reversing mechanism is installed on the side of the mounting plate.

[0011] Furthermore, the output shaft of the first drive motor is coaxially arranged with the clamped bearing rings.

[0012] Furthermore, the reversing mechanism includes a suspension and a second drive motor. The suspension is horizontally fixed to the side of the mounting plate and remains perpendicular to the mounting plate. The second drive motor is fixed to the suspension, and the clamping mechanism is mounted on the output shaft of the second drive motor.

[0013] Furthermore, the clamping mechanism includes a guide seat, a bidirectional threaded rod, a nut seat, and arc-shaped grippers. The guide seat is fixed to the output shaft end face of the second drive motor. A guide groove is provided below the guide seat. The bidirectional threaded rod is rotatably installed in the guide groove. The two nut seats are respectively limited and slidably installed in the guide groove and threadedly fitted on both sides of the bidirectional threaded rod. Arc-shaped grippers that cooperate with each other to clamp and fix the bearing ring are fixedly installed at the lower end of the two nut seats.

[0014] Furthermore, the clamping surfaces of the two arc-shaped jaws are provided with anti-slip textures, and one end of the bidirectional threaded rod extends through to the outer side of the guide seat and is equipped with a handle.

[0015] Furthermore, the testing structure includes a stand and a dial indicator. The stand is vertically installed above the base, and the dial indicator is horizontally fixed to the top of the stand.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0017] This invention sets the clamping mechanism on the reversing mechanism. After the parallelism test of one end face of the bearing ring is completed, the reversing mechanism drives the bearing ring to rotate half a turn, which adjusts the other end face of the bearing ring to face the test structure. There is no need to remove the bearing ring, reverse the direction and re-clamp it. Parallelism test of both end faces can be performed, ensuring high continuity of the test process, saving time and effort and improving test efficiency. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0025] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0026] Please see Figures 1-4 This utility model provides a bearing ring accuracy testing device, including a base 1. A translation mechanism 2 is provided on one side of the base 1, and a testing structure 6 for testing the parallelism of the bearing ring end face is provided on the other side. A driving mechanism 3 is provided above the translation mechanism 2, and a reversing mechanism 4 is provided on the side of the driving mechanism 3. A clamping mechanism 5 is provided below the reversing mechanism 4. The clamping mechanism 5 is used to clamp and fix the bearing ring to be tested. The reversing mechanism 4 is used to drive the bearing ring to rotate and adjust to realize the switching of the testing end face. The driving mechanism 3 is used to drive the bearing ring to rotate and adjust to realize the full circumference testing of the bearing ring end face. The translation mechanism 2 is used to drive the bearing ring to feed towards the testing structure 6 or to retract away from the testing structure 6.

[0027] When using the detection device provided by this utility model to detect the parallelism of the end face of a bearing race, the bearing race is clamped and fixed by the clamping mechanism 5. Then, the translation mechanism 2 works to move the clamped bearing race towards the detection structure 6 until it is in place. Next, the drive mechanism 3 works to rotate the bearing race, thus realizing the parallelism detection of one end face of the bearing race. After the end face of one side is detected, the translation mechanism 2 works to move the bearing race back. Then, the reversing mechanism 4 works to rotate the clamped bearing race half a turn, adjusting the other end face to face the detection structure 6. Then, the translation mechanism 2 works to move the bearing race towards the detection structure 6 until it is in place. The above process is repeated to complete the parallelism detection of the other end face of the bearing race.

[0028] This device sets the clamping mechanism 5 on the reversing mechanism 4. After the parallelism test of one end face of the bearing ring is completed, the reversing mechanism 4 drives the bearing ring to rotate half a turn, which can adjust the other end face of the bearing ring to face the test structure 6. The parallelism test of both end faces can be performed without removing the bearing ring, reversing the direction and re-clamping it. This ensures high continuity of the test process, saves time and effort and improves test efficiency.

[0029] Specifically, the translation mechanism 2 includes a mounting base 21 fixed on one side above the base 1, a power guide rail 22 mounted on the mounting base 21, a movable seat 23 mounted on the power guide rail 22, and a mounting platform 24 fixed on the top of the movable seat 23. The movable seat 23 can be adjusted to move along the power guide rail 22. The drive mechanism 3 is arranged above the mounting platform 24 and works through the power guide rail 22 to drive the movable seat 23 to move left and right along the power guide rail 22 to provide drive for the feeding and retraction of the bearing ring.

[0030] Specifically, the drive mechanism 3 includes a vertical plate 31, a first drive motor 32, and a mounting plate 33. The vertical plate 31 is vertically fixed above the mounting platform 24. The first drive motor 32 is fixed on the vertical plate 31. The mounting plate 33 is fixed on the end of the output shaft of the first drive motor 32. The reversing mechanism 4 is installed on the side of the mounting plate 33. When the first drive motor 32 works, its output shaft can drive the mounting plate 33 to rotate, thereby providing drive for the full circumference detection of the bearing ring rotation.

[0031] In addition, the output shaft of the first drive motor 32 is coaxially arranged with the clamped bearing ring to ensure that the clamped bearing ring can rotate around the axis of the output shaft of the first drive motor 32, thus avoiding eccentric rotation of the bearing ring and affecting the normal detection of the end face.

[0032] Specifically, the reversing mechanism 4 includes a suspension 41 and a second drive motor 42. The suspension 41 is horizontally fixed to the side of the mounting plate 33 and remains perpendicular to the mounting plate 33. The second drive motor 42 is fixed on the suspension 41. The clamping mechanism 5 is installed on the output shaft of the second drive motor 42. Through the operation of the reversing mechanism 4, its output shaft can drive the clamping mechanism 5 and the bearing ring to rotate, thereby realizing the rotation reversing adjustment of the bearing ring so as to switch the end face of the bearing ring.

[0033] Specifically, the clamping mechanism 5 includes a guide seat 51, a bidirectional threaded rod 52, a nut seat 53, and arc-shaped grippers 54. The guide seat 51 is fixed to the output shaft end face of the second drive motor 42. A guide groove 511 is provided below the guide seat 51. The bidirectional threaded rod 52 is rotatably installed in the guide groove 511. The two nut seats 53 are respectively limited and slidably installed in the guide groove 511 and threadedly fitted on both sides of the bidirectional threaded rod 52. The lower ends of the two nut seats 53 are fixedly installed with arc-shaped grippers 54 that cooperate with each other to clamp and fix the bearing ring. The bearing ring is placed between the two arc-shaped grippers 54, and then the bidirectional threaded rod 52 is screwed on. The bidirectional threaded rod 52 engages and drives the two nut seats 53 to move closer to each other, thereby driving the two arc-shaped grippers 54 to clamp the bearing ring, thereby fixing the bearing ring and ensuring stability during testing.

[0034] Specifically, anti-slip textures are provided on the clamping surfaces of the two arc-shaped jaws 54 to increase the friction between the arc-shaped jaws 54 and the outer edge wall of the bearing ring, further ensuring the stability during clamping. One end of the bidirectional threaded rod 52 extends through to the outer side of the guide seat 51 and is equipped with a handle 521. By pinching the handle 521, it is convenient to apply force to rotate and adjust the bidirectional threaded rod 52.

[0035] Specifically, the testing structure 6 includes a stand 61 and a dial indicator 62. The stand 61 is vertically installed above the base 1, and the dial indicator 62 is horizontally fixed at the top of the stand 61. The dial indicator 62 is installed above the base 1 using the stand 61, with the testing end face of the dial indicator 62 facing the translation mechanism 2. When the bearing ring is fed into place, the testing end of the dial indicator 62 abuts against the end face of the bearing ring, which facilitates the testing of the parallelism of the bearing ring end face.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
