Description

Technical Field

[0001] The utility model relates to the technical field of wheel production auxiliary equipment, in particular to a multifunctional clamping claw for automobile wheel production. Background Art

[0002] The automobile wheel is one of the important parts of the automobile. It is in direct contact with the road surface and works together with the automobile suspension to mitigate the impact of the automobile when driving, ensuring that the automobile has good ride comfort and driving smoothness; ensuring good adhesion between the wheel and the road surface; improving the automobile's traction, braking and passability; bearing the weight of the car, the important role played by the tire on the car is increasingly valued by people. In the production process of automobile wheels, in order to avoid the wheel shaking back and forth on the workbench during the grinding process, it is necessary to use a clamp to clamp and position the formed wheel to facilitate the subsequent grinding process of the wheel.

[0003] When the existing mechanical clamps for automobile wheel production are in use, the staff will place the wheel that needs to be polished on the workbench, and then use the mechanical clamps on the workbench to clamp the rim of the wheel to fix the tire. When the top surface of the wheel is polished, the clamping of the wheel is cancelled by controlling the clamping jaws, and the direction of the polished surface of the wheel is changed, and the wheel is then clamped and fixed by the clamping jaws, and the staff then polishes the bottom surface of the wheel. When the staff polishes the rim of the wheel, part of the rim is supported by the clamping jaws, so the part of the rim supported by the clamping jaws cannot be polished. If the rim part is to be fully polished, the control clamping jaws must be used to adjust the angle of the wheel on the clamping jaws. Although the existing clamping jaws can achieve a good clamping effect on the wheel that needs to be processed, each time a wheel that needs to be polished is processed, the opening and closing of the clamping jaws and the position of the wheel need to be adjusted multiple times, which increases the workload of the staff and easily affects production efficiency.

[0031] Working principle:

[0032] First, place the wheel to be polished between two symmetrical jaw assemblies 4, and then control the first electric push rod 9 to drive the sliding jaw assembly 4 set on the first connecting plate 3 to approach the other group of jaw assemblies 4. The relative movement of the two jaw assemblies 4 is used to complete the support and fixation of the wheel to be processed. After the wheel to be processed is fixed, the staff can polish the top of the wheel. After the top of the wheel is polished, the second electric push rod 1407 and the third electric push rod 1411 are controlled to work at the same time. After the second electric push rod 1407 and the third electric push rod 1411 work, they push the rack 1404 to slide on the guide rod 1402. When the rack 1404 slides, it cooperates with the gear 1401 to complete the rotation of the gear 1401, realizing a 180-degree rotation of the first connecting plate 3, the jaw assembly 4 and the wheel. At this time, the rotated wheel and the wheel before rotation are swapped, and then the bottom of the wheel can be directly polished.

[0033] When the top and bottom of the wheel are polished and the rim of the wheel needs to be polished, the first connecting plate 3, the clamping jaw assembly 4 and the wheel are rotated 90 degrees by controlling any one of the second electric push rods 1407 and the third electric push rod 1411. At this time, the wheel is in an upright state, and then the drive motor 1012 is controlled to rotate. When the drive motor 1012 rotates, it drives the drive wheel 1010 to rotate. When the drive wheel 1010 rotates, it drives the wheel to rotate, thereby completing the angle adjustment of the wheel between the two clamping jaw assemblies 4.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
