[0002] The main function of the wheel hub bearing is to bear the load and provide precise guidance for the rotation of the wheel hub. It bears both axial load and radial load and is a very important component. Traditional automobile wheel bearings are composed of two sets of tapered roller bearings or ball bearings. The installation, oiling, sealing and clearance adjustment of the bearings are all carried out on the automobile production line.

[0003] Because automotive bearings play a vital role inside the car, there must be strict requirements on the quality, quality and performance of the bearings. After the automotive bearings are produced, they need to be sampled and tested. The test platform bracket in the existing technology can only meet the testing of bearings of one specification. When processing and testing bearings of other specifications, it is necessary to replace another platform bracket, which undoubtedly increases the burden at work. At the same time, equipping each specification of bearings with a processing and testing platform bracket will also increase the economic burden. Utility Model Content

[0025] The above scheme is adopted: the sliding clamp 15 is driven to slide by the second motor 11, so that automobile wheel hub bearings of different specifications can be clamped, so as to facilitate the staff to test and process the bearings. Then the staff can test the automobile wheel hub bearings, such as by rotating the automobile bearing body 19 to understand whether its speed and torque are normal, and test whether its internal center of the circle is on the same straight line. If there is no problem, the test is passed. If there is a problem, it will be processed and repaired immediately.

[0026] like Figures 1 to 5 As shown, a fixing plate 17 is rotatably provided on one side of the rotating threaded shaft 14 , and the fixing plate 17 is fixedly connected to the fixing sleeve 9 , and a supporting plate 16 is rotatably provided on the other side of the rotating threaded shaft 14 , and the supporting plate 16 is fixedly connected to the supporting frame 10 .

[0027] With the above solution, the support plate 16 and the fixed plate 17 support the rotating threaded shaft 14 together.

[0028] like Figures 1 to 5 As shown, a threaded block 3 is fixedly provided on the outer side of the fixed frame 8, a screw rod 2 is slidably provided inside the threaded block 3, a first motor 1 is fixedly provided on one end of the screw rod 2, a connecting frame body 20 is fixedly provided on the outer side of the first motor 1, a support block 4 is fixedly provided on the other side of the screw rod 2, and the support block 4 is fixedly connected to the connecting frame body 20.

[0029] The above solution is adopted: the first motor 1 drives the fixing frame 8 to adjust the height to adapt to the height of the staff and increase the comfort during work. At the same time, the support block 4 is used to support the screw rod 2, while ensuring that the center of the circle at its front and rear ends is on the same straight line.

[0030] like Figures 1 to 5 As shown, a support shaft 5 is fixedly disposed inside the support block 4 , a linear bearing 7 is slidably disposed outside the support shaft 5 , a sliding block 6 is fixedly disposed outside the linear bearing 7 , and the sliding block 6 is fixedly connected to a fixed frame 8 .

[0031] With the above solution, the linear bearing 7 is used to reduce the friction of the support shaft 5, and the sliding blocks 6 on both sides are used to maintain the balance of the fixed frame 8. It is easy to be unbalanced left and right if only relying on the threaded block 3 for support.

[0032] The working principle and use process of this utility model:

[0033] Before using a connecting frame for automobile bearing processing and testing, first, turn on the switch of the second motor 11, the second motor 11 drives the main gear 12 to rotate, and when the main gear 12 rotates, it drives the sub-gear 13 to rotate, and the sub-gear 13 drives the rotating threaded shaft 14 on the other side to rotate. The outer thread of the rotating threaded shaft 14 is connected with a sliding clamp 15, so when the rotating threaded shaft 14 rotates, the sliding clamp 15 is driven to slide inside the fixed sleeve 9, and the automobile bearing sleeve 18 is clamped at the same time. Then the staff can test the automobile bearing body 19, such as by rotating the automobile bearing body 19 to understand whether its speed and torque are normal, and test whether its internal center of the circle is in the same straight line. If there is no problem, it passes the test. If there is a problem, it is immediately processed and trimmed. If the problem is large, it is reworked. The support plates 16 and the fixed plates 17 at both ends of the rotating threaded shaft 14 are used to fix and support the rotating threaded shaft 14. The support frame 10 is used to support the main gear 12 to prevent it from falling to the ground. At the rear side of the connecting frame body 20 A first motor 1 is also provided, which drives the screw rod 2 to rotate, the screw rod 2 drives the threaded block 3 to move, and the threaded block 3 drives the fixed frame 8 to move. Since the fixed frame 8 is fixedly connected to the fixed sleeve 9, the fixed sleeve 9 also moves when the fixed frame 8 moves. In order to adapt to the height of the staff and facilitate the testing work of the staff, the sliding blocks 6 on both sides of the fixed frame 8 are used to support the fixed frame 8. It is easy to be unbalanced left and right if only supported by the threaded block 3. The supporting block 4 at the other end of the threaded block 3 is used to support the screw rod 2. At the same time, the supporting block 4 is also used to support the support shaft 5 and the sliding block 6 on the left and right sides. The linear bearing 7 inside the sliding block 6 is used to reduce the friction between the support shaft 5 and the sliding block 6 and increase the smoothness during sliding. The beneficial effects of the utility model are as follows: the utility model can clamp automobile wheel hub bearings of different specifications, so as to facilitate the staff to test and process the bearings. There is no need to equip each specification of automobile wheel hub bearings with a processing and testing connecting frame, which reduces the workload and also reduces the work cost.
