Description

Technical Field

[0001] This utility model relates to the field of wheel spoke clamping technology, specifically to a multi-jaw clamping device for wheel spokes. Background Technology

[0002] During the processing of wheel spokes, in order to ensure that the position of the wheel spokes does not change, a clamping device is needed to quickly clamp and position the wheel spokes. For example, patent document CN216098498U discloses a special device for clamping wheel spokes. This special device has a liftable positioning column in the middle of the table. The positioning column and the support block inside it can position and limit the wheel spokes. By rotating the rotating rod, the connecting plate and the connecting rod are driven to rotate. The connecting rod contacts the slider and squeezes the slider, so that it squeezes the support rod and contacts the wheel spoke, thus limiting the wheel spokes. After the limiting is completed, the slider slides inside the electric slide rail, thereby driving the connecting block to move and clamping the outer side of the wheel spoke through the clamping groove.

[0003] However, when the above device is used to longitudinally position the spokes, it is necessary to rotate multiple screws to make the base plate squeeze the spokes. Due to the large number of screws, the operator needs to spend a lot of time to operate, which reduces the ease of operation and clamping efficiency of the device. Utility Model Content

Detailed Implementation

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model discloses a multi-jaw clamping device for wheel spokes.

[0026] This utility model provides, for example Figures 1-3 The multi-jaw clamping device shown includes a base 1, a groove on the top of the base 1, a support ring 2 fixedly mounted on the top of the base 1, and multiple support frames 3 evenly distributed axially fixed on the outer wall of the support ring 2. A sliding hole is provided inside the support frame 3, and an adjusting screw 4 is rotatably mounted inside the sliding hole. A movable clamping plate 5 is threaded onto the wall of the adjusting screw 4. The outer wall of the movable clamping plate 5 contacts and engages with the inner wall of the sliding hole. A crossbar 6 is fixedly mounted at the upper end of the movable clamping plate 5, and two ends of the crossbar 6 are rotatably mounted with pressing jaws 7. The end of the pressing jaws 7 has a rotating groove that cooperates with the rotation of the movable clamping plate 5. Each of the multiple pressing jaws 7 has a pushing and pressing assembly at its bottom for pushing the pressing jaws 7 to rotate.

[0027] The top of the base 1 is provided with a drive clamping mechanism for driving multiple adjusting screws 4 to rotate synchronously. The drive clamping mechanism includes a drive motor 8, which is fixedly mounted on the top of the base 1. A drive bevel gear 9 is fixedly mounted at the end of the output shaft. Transmission bevel gears 10 are fixedly sleeved on the rod walls of the multiple adjusting screws 4. A first bevel gear ring 11 is rotatably sleeved on the upper end of the outer wall of the support ring 2. The first bevel gear ring 11 is configured to cooperate with the multiple transmission bevel gears 10. A second bevel gear ring 12 is fixedly mounted on the bottom of the first bevel gear ring 11. The second bevel gear ring 12 is sleeved on the outside of the support ring 2 and is configured to cooperate with the drive bevel gear 9.

[0028] In order to simultaneously push the downward clamping jaws 7 to complete the longitudinal compression of the wheel spokes, such as Figure 1 , Figure 3 and Figure 4 As shown, the push clamping assembly includes a push plate 13, a moving groove is provided on the top of the moving clamping plate 5, a guide rod 14 is fixedly provided on the bottom of the inner wall of the moving groove, the end of the push plate 13 is slidably disposed in the moving groove and slidably sleeved on the outside of the guide rod 14, an electric push rod 15 is fixedly provided on the bottom of the inner wall of the groove, a connecting plate 16 is fixedly provided on the end of the output shaft of the electric push rod 15, and a plurality of axially evenly distributed telescopic rods 17 are fixedly provided on the outer wall of the connecting plate 16, and the telescopic rods 17 are fixedly connected to the push plate 13.

[0029] Working principle: When it is necessary to clamp the spokes, first place the spokes outside the support ring 2 and contact the top of multiple support frames 3. Start the drive motor 8. The motor output shaft drives the drive bevel gear 9 to rotate. The drive bevel gear 9 meshes with the second bevel gear ring 12, which drives the second bevel gear ring 12 and the first bevel gear ring 11 above it to rotate synchronously. The first bevel gear ring 11 meshes with multiple transmission bevel gears 10, so that the adjusting screw 4 rotates synchronously. Since the adjusting screw 4 is threadedly connected to the moving clamping plate 5, the moving clamping plate 5 moves radially in the sliding hole. Through the crossbar 6, it drives the lower clamping claw 7 to approach the outer periphery of the spokes, realizing multi-directional lateral clamping.

[0030] After the lateral clamping is completed, the electric push rod 15 is activated, and its output shaft pushes the connecting plate 16 to move upward. The connecting plate 16 drives the push plate 13 to slide upward along the guide rod 14 through the telescopic rod 17. The top inclined surface of the push plate 13 pushes the lower clamping claw 7 to rotate around the cross rod 6, so that the end of the lower clamping claw 7 presses down to the top of the wheel spoke, completing the longitudinal clamping. In the whole process, the driving clamping mechanism and the pushing clamping assembly work together, eliminating the need to manually adjust the screws one by one, which significantly improves the clamping efficiency.

[0031] When the spokes are released, the electric push rod 15 retracts first, the pressure gripper 7 resets under gravity, then the drive motor 8 reverses, and the adjusting screw 4 drives the moving clamp 5 to move in the opposite direction, thus releasing the spokes.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
