[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] Please see Figures 1-5 The present invention provides the following technical solution: a chuck for processing automobile wheel hubs, including a fixed base 1, a hydraulic rod 2 installed inside the fixed base 1, a supporting outer ring 3 connected to the output end of the hydraulic rod 2, a connecting rod 4 connected to the inner side of the supporting outer ring 3, a supporting inner ring 5 connected to the end of the connecting rod 4, an adjusting rod 6 hinged above both the supporting outer ring 3 and the supporting inner ring 5, and a push rod 7 hinged to the upper end of the adjusting rod 6;

[0025] Furthermore, the outer support ring 3 and the inner support ring 5 are connected by a connecting rod 4. The position of the connecting rod 4 is offset from the position of the rotating rod 11, which can avoid the connecting rod 4 and the rotating rod 11 from blocking each other and ensure that the outer support ring 3 and the inner support ring 5 can move smoothly vertically; the fixed base 1 is provided with a fixing component for clamping the car wheel hub.

[0026] The fixing assembly includes a rotating rod 11 rotatably connected to the fixing base 1, a gear 13 keyed to the lower end of the rotating rod 11, a support plate 12 installed at the upper end of the rotating rod 11, a compression spring 10 connected inside the support plate 12, a moving rod 8 connected to the end of the compression spring 10, and a clamping block 9 installed at the upper end of the moving rod 8.

[0027] The push rod 7 and the fixed base 1 form a sliding structure. The position of the push rod 7 and the position of the moving rod 8 are set to correspond to each other. When the driving adjustment rod 6 is rotated, the push rod 7 can be smoothly controlled to move horizontally and push the moving rod 8.

[0028] The moving rod 8 has a "dry" shape structure. The moving rod 8 and the support plate 12 form an elastic structure through a compression spring 10. The lowest point of the moving rod 8 is higher than the highest point of the fixed seat 1, which can prevent the moving rod 8 from detaching from the support plate 12 and enable the moving rod 8 to move smoothly horizontally. The clamping block 9 has an arc-shaped structure, and there is a gap between the clamping block 9 and the support plate 12, which can avoid the sliding friction between the clamping block 9 and the support plate 12. By driving the clamping block 9 to move, it can adapt to the size of the automobile wheel hub for fixing.

[0029] A motor 14 is installed inside the fixed seat 1. The output end of the motor 14 is connected to a rotating shaft 15. The upper end of the rotating shaft 15 is installed with a turntable 16, and the outer side of the turntable 16 is connected with a tooth block 17.

[0030] Tooth blocks 17 are distributed at equal angles at the connection between the turntable 16 and the gear 13. The gear 13 and the support plate 12 are coaxially connected. The rotation of the turntable 16 can drive the rotation of the gear 13, thereby controlling the rotation of the support plate 12.

[0031] When machining the outer ring of an automobile wheel hub, the clamping blocks 9 can be distributed at positions close to the center of the fixed seat 1. Place the automobile wheel hub on the fixed seat 1, and use the support plate 12 to support the automobile wheel hub. At this time, the clamping blocks 9 are located inside the inner ring of the automobile wheel hub. Open the hydraulic rod 2 to push the support outer ring 3 connected to the output end to move upward. The support outer ring 3带动 the connecting rod 4 connected to the inner side to move upward, thereby controlling the upward movement of the support inner ring 5 installed at the end of the connecting rod 4. The support inner ring 5带动 the adjusting rod 6 hinged at the upper end to rotate. The adjusting rod 6 pushes the push rod 7 hinged at the upper end to move in the direction close to the moving rod 8, pushing the moving rod 8 to slide inside the support plate 12, and the moving rod 8 squeezes and stores energy in the compression spring 10. At the same time, the moving rod 8带动 the clamping block 9 installed at the upper end to move in the direction close to the inner ring of the automobile wheel hub to fix the automobile wheel hub, and then the outer ring of the automobile wheel hub can be machined.

[0032] The hydraulic rod 2 controls the outer support ring 3 to move downwards, thereby controlling the inner support ring 5 to move downwards. This drives the adjusting rod 6 to move the push rod 7 away from the inner ring of the car wheel hub. At this time, the compression spring 10 controls the moving rod 8 to reset, causing the clamping block 9 to move away from the inner ring of the car wheel hub, releasing the lock on the car wheel hub. The car wheel hub is then removed from the support plate 12. The motor 14 is then powered on, controlling the rotating shaft 15 connected to the output end to rotate, thereby controlling the rotation of the turntable 16 mounted at the end. The toothed blocks 17 mounted on the outer side of the turntable 16 drive the meshing gear 13. Rotation of gear 13 controls the coaxially connected support plate 12 to rotate, changing the position of clamping block 9 so that clamping block 9 is located close to the outer edge of fixed seat 1. The car wheel hub is placed on support plate 12. At this time, clamping block 9 is located at the outer ring of the car wheel hub. When the support outer ring 3 is moved upward, the hinged adjusting rod 6 can be pushed to rotate, thereby controlling push rod 7 to move towards moving rod 8. Pushing moving rod 8 drives the clamping block 9 installed at the upper end to move towards the outer ring of the car wheel hub, fixing the car wheel hub, and then the inner ring of the car wheel hub can be processed.
