The mandrel connects to the brake disc within the shaft holes. The base is located within the receiving groove. N second positioning holes on the first end face of the base correspond one-to-one with N first positioning holes opposite to the base on the closed end. The mandrel has M third positioning holes opposite to the base, and the first end face of the base has M fourth positioning holes, with the third and fourth positioning holes corresponding to each other. The brake disc drives the mandrel to rotate until the first and second positioning holes align with each other. Telescopic components extend from the second positioning holes and partially embed into the first positioning holes, and the third and fourth positioning holes align with each other. The solution provided in this application can solve the problem of unstable brake disc and fixture in the prior art.

[0024] 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.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a grinding machine support fixture for improving the grinding accuracy of the raceway of a double-row tapered wheel hub bearing, comprising a worktable 1, a first telescopic rod 2, bolts 3, a support frame 4, a fixing rod 5, a first threaded rod 6, a connecting block 7, a second threaded rod 8, a first gear 9, a toothed belt 10, a second gear 11, a first motor 12, a second motor 13, a mounting base 14, a second telescopic rod 15, and a clamping plate 16.

[0026] When a stable installation of a double-row tapered wheel hub bearing is required, as shown in the attached... Figure 1 and attached Figure 5 As shown, a second telescopic rod 15 is provided on the upper, lower, front and rear sides of the right end of the mounting base 14. A clamping plate 16 is provided on the upper end of the second telescopic rod 15. The second telescopic rod 15 is symmetrically arranged about the center line of the clamping plate 16. The cross-section of the clamping plate 16 is arc-shaped. First, the worktable 1 is stably installed in position on the grinding machine by bolts 3. Then, the middle part of the double-row tapered wheel hub bearing is inserted into the outside of the clamping plate 16. At this time, the second telescopic rod 15 is activated to drive the clamping plate 16 to unfold and fit against the inner wall of the double-row tapered wheel hub bearing to limit its position.

[0027] When the height of the grinding machine support fixture needs to be adjusted, as shown in the attached document... Figure 1 and attached Figure 2 As shown, after the position of the double-row tapered wheel hub bearing is fixed, the height of the support device on the grinding machine support fixture is adjusted according to the height of the grinding device. The first motor 12 is started to drive the second threaded rod 8 to rotate. Since the upper end of the first threaded rod 6 is provided with the first gear 9, and the outer side of the first gear 9 is connected to the toothed belt 10, the outer side of the first gear 9 and the toothed belt 10 are connected in a meshing manner. Therefore, when the second threaded rod 8 rotates, it also drives the second gear 11 to rotate. Since the outer side of the second gear 11 is connected to the toothed belt 10 in a meshing manner, the second gear 11 is driven by the toothed belt 10, so that the first gear 9 and the second gear 11 rotate in the same direction. The first gear 9 also drives the first threaded rod 6 to rotate in the same direction. The outer side of the first threaded rod 6 is connected to the connecting block 7 in a threaded manner, and the rear end of the connecting block 7 is connected to the second threaded rod 8 in a threaded manner. Therefore, the first threaded rod 6 and the second threaded rod 8 drive the connecting block 7 to achieve up and down adjustment as a whole, thereby realizing the height adjustment of the upper support device of the grinding machine support fixture.

[0028] When it is necessary to use a grinding machine support fixture to improve the grinding accuracy of the raceway of a double-row tapered wheel hub bearing, as shown in the attached... Figure 1 and attached Figure 2 As shown in the figure, the second motor 13 is started at this time to drive the mounting base 14 to rotate as a whole. Since the lower end of the support frame 4 is connected to the fixed rod 5, the starting bolt 3 extends and retracts to drive the support frame 4 to move left and right along the path of the fixed rod 5, thereby driving the installed double-row tapered wheel hub bearing and the grinding device to perform raceway grinding. The movement of the support frame 4 improves the grinding accuracy of the double-row tapered wheel hub bearing.

[0029] This is the entire working process of the grinding machine support fixture for improving the grinding accuracy of the raceway of double-row tapered wheel hub bearings. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
