Description

Technical Field

[0001] The invention relates to the technical field of wheel hub manufacturing, in particular to a clamping tool for manufacturing and processing automobile wheel hubs. Background Art

[0002] The wheel hub is a cylindrical metal component with the inner contour of the tire supporting the tire and the center mounted on the shaft. It is also called a rim, steel ring, wheel, or tire bell. There are many types of wheel hubs depending on the diameter, width, molding method, and material. In the past, most car wheel hub bearings were used in pairs of single-row tapered roller or ball bearings. With the development of technology, car wheel hub units have been widely used in cars. The scope and amount of use of wheel hub bearing units are increasing, and they have developed to the third generation: the first generation is composed of double-row angular contact bearings, and the second generation has a flange on the outer raceway for fixing the bearings. The bearings can be simply put on the axle and fixed with nuts, making the car easier to repair. The third generation wheel hub bearing unit uses a bearing unit in combination with an anti-lock brake system. The wheel hub unit is designed with an inner flange and an outer flange. The inner flange is fixed to the drive shaft with bolts, and the outer flange installs the entire bearing together.

[0048] The implementation principle of this embodiment is:

[0049] When the inner wall of the wheel hub needs to be processed, the wheel hub is first placed on the top of the support plate 1, and then the third starts to work to drive the screw rod 31, and the screw rod 31 and the threaded tube 30 are used to push the protective shell 24 to move, and the protective shell 24 drives the slide tube 25 to move. After the rubber head 27 contacts the outer surface of the wheel hub, the protective shell 24 will continue to move until the slide rod 26 slides inside the slide tube 25 and compresses the pressure spring 28, so that the pressure spring 28 is deformed and has a certain thrust, which is used to fix the wheel hub to prevent the wheel hub from shaking. After the inner wall and the upper surface of the wheel hub are polished, the fourth motor 35 drives the connecting plate 34, and the connecting plate 34 is fixedly connected to the baffle 7. When the fourth motor 35 drives the connecting plate 34 to rotate, the connecting plate 34 can drive the outer clamping device 8 to rotate, so as to achieve the purpose of turning the wheel hub over. After the wheel hub is turned over, it will be placed on the top of the inner clamping device 6;

[0050] When the wheel hub is placed in the inner clamping device 6, the second motor 13 drives the collecting rod 14 to rotate, and the collecting rod 14 rotates inside the fixing box 12 and the placing plate 16, so that the cable 15 is wrapped around the surface of the collecting rod 14, and the guide block 18 is pulled by the cable 15 to slide on the outside of the guide rod 19. When the guide block 18 slides, pressure is formed on the support spring 20, so that the support spring 20 is compressed. After the limit plate 21 and the rubber plate 22 are inserted into the inside of the wheel, the second motor 13 rotates in the opposite direction, so that the cable 15 is separated from the surface of the collecting rod 14. When the guide block 18 loses its tension, the support spring 20 recovers its deformation, pushing the guide block 18 to slide outward, so that the rubber plate 22 fits the inner wall of the wheel hub, and the wheel hub is fixed. At this time, the lower surface and the upper surface of the wheel hub are in an alternating position, and the outer wall of the wheel hub is not blocked. Then the first motor 3 starts to work and drives the threaded rod 4 to rotate, and the inner clamping device 6 is driven to move by the coordinated use of the threaded rod 4 and the threaded sleeve 5;

[0051] When facing workers of different heights, the fifth motor 43 starts to work, driving the toothed screw 42 to rotate, and the toothed screw and the threaded block 41 are used in conjunction to drive the movement of the connecting rod 40. When the connecting rod 40 moves, it will drive the connecting frame 38 to move, and the connecting frame 38 will drive the cross rod 39 to make a cross movement. By changing the angle of the cross rod 39, the purpose of lifting and lowering the support rod 37 is achieved. The slide plate 46 is fixedly connected to the bottom of the limit box 2. When the support rod 37 is lifted or lowered, it can drive the structure on the top of the support plate 1 to lift or lower, so as to be suitable for workers of different heights.

[0053] The sliding cylinder 25, the sliding rod 26 and the supporting spring 20 are used in coordination to clamp the outer side of the wheel hub. The screw rod 31, the threaded cylinder 30 and the third motor 32 are used in coordination to push the protective shell 24 to move. The addition of the rubber head 27 increases the friction force. The connecting plate 34 and the fourth motor 35 are used in coordination to drive the outer clamping device 8 to rotate. By using the above structure, the wheel hub can be driven to flip, thereby effectively improving the working efficiency. The second motor 13, the cable 15 and the guide block 18 are used in coordination to drive the guide block 18 and the limit plate 21 to move. The guide block 18, the guide rod 19 and the supporting spring 20 are used in coordination to increase the friction force. , plays a role in pushing the limit plate 21 to move, the first motor 3, the threaded rod 4 and the threaded sleeve 5 are used in combination to drive the inner clamping device 6 to move. By using the above structure, the wheel can be driven to move quickly and fixed, thereby achieving the purpose of saving physical strength. By using the fifth motor 43, the toothed screw 42 and the internal threaded block 41, the connecting rod 40 is moved. By adding the connecting rod 40, the connecting frame 38 is driven to slide. By using the connecting frame 38, the connecting shaft 45 and the support rod 37, the cross rod 39 is facilitated to rotate. By using the above structure, the support plate 1 can be driven to move up and down, so that it is suitable for workers of different heights.
