The processing of titanium alloy watchband parts usually includes steps such as cutting and grinding. And the grinding step includes rough grinding for deburring and fine grinding for increasing smoothness. After grinding, the watchband needs to be rinsed to remove impurities such as cutting fluid and abrasive on the watchband parts. Finally, the watchband parts are assembled and detected to check whether the watchband parts can be smoothly connected together. Multiple stations are required for processing to improve processing efficiency.

[0003] In the prior art, a Chinese patent with the authorization announcement number of CN215700837U discloses a fixture for watchband processing.

When the socket spring is in the natural elongation state, the horizontal height of the positioning plate is higher than the horizontal height of the upper bottom surface of the rotating plate, so that the positioning plate is attached to the outer surface of the rotating plate to achieve the effect of positioning the rotating plate. When the rotating plate needs to be rotated, by grasping the handle rod and pressing it down until the horizontal height of the upper surface of the positioning plate is lower than the bottom surface height of the rotating plate, the positioning of the rotating plate by the positioning component is released. After the rotating plate is rotated by 90°, the handle rod is released, and the elastic force of the socket spring drives the positioning plate to move upward until the horizontal height of the positioning plate is higher than the bottom surface height of the rotating plate, realizing the effect of positioning the rotating plate again. The operation is simple and convenient.

[0019] 3. The utility model is provided with a clamping component. When clamping the watch band parts, the watch band parts are placed between the inner sides of the clamping plate and the rectangular frame, and then the adjusting bolt is screwed. The adjusting bolt drives the clamping plate to move inward, and the clamping plate cooperates with the inner surface of the rectangular frame to clamp and fix the watch band parts, ensuring the stability during the processing of the watch band parts. When the watch band parts need to be turned over for processing, by grasping the two handle plates and lifting the rectangular frame upward, the slider moves upward along the guiding box, and then the rectangular frame is rotated along the pin shaft on the slider, so that the bottom surface of the rectangular frame faces upward, facilitating the processing of grinding and polishing the bottom surface of the watch band parts. There is no need to take out the watch band parts from the clamping component to turn them over for processing, and the operation is simple and convenient. Description of the Drawings

Specific embodiments

[0028] Example:

[0029] As Figures 1-5 shown, the embodiment of the present invention provides a multi-station fixture for processing a titanium alloy watch strap, including a workbench 1, a pin shaft 2, a rotating plate 3, a positioning assembly, and a clamping assembly. A rotating plate 3 is rotatably arranged on the central upper surface of the workbench 1 through a pin shaft 2, a positioning assembly for positioning the rotating plate 3 is fixedly arranged below the outer surface of the workbench 1, and clamping assemblies are fixedly arranged at the four side surfaces of the upper surface of the rotating plate 3.

[0030] By providing a rotating plate 3, a positioning component, and a clamping component, workpieces and workers for different processing steps are arranged at the four positions of the workbench 1. When processing watchband parts, the watchband parts are clamped by the clamping component. After rough polishing, the positioning of the rotating plate 3 is released through the positioning component, and the rotating plate 3 is rotated by 90°. The rough-polished watchband parts enter the next station for fine polishing. At this time, there is also a clamping component at the rough polishing station. Then, the parts to be processed are placed into the clamping component for processing. Similarly, after the rough polishing and fine polishing of the watchband parts are completed, the rotating plate is rotated again so that the fine-polished watchband parts enter the cleaning station, and the rough-polished watchband parts enter the fine polishing step, achieving the effect of processing watchband parts at multiple stations, ensuring the continuity of processing and the work efficiency.

[0031] In this embodiment, the positioning component includes a fixed plate 4, a guide rod 401, a positioning plate 402, a socket spring 403, and a gripper rod 404. The fixed plate 4 is fixedly arranged at the center of the outer surface of the workbench 1. The center of the upper surface of the fixed plate 4 is fixedly provided with a guide rod 401. The top of the guide rod 401 is provided with a positioning plate 402 through it. A socket spring 403 is fixedly arranged between the upper surface of the fixed plate 4 and the bottom surface of the positioning plate 402. The outer surface of the positioning plate 402 is fixedly provided with a gripper rod 404.

[0032] In this embodiment, a through hole matching the guide rod 401 is provided through the center of the upper surface of the positioning plate 402, and the guide rod 401 is inserted into the through hole. The inner surface of the positioning plate 402 is closely attached to the outer surface of the workbench 1.

[0033] In this embodiment, when the socket spring 403 is in a natural elongation state, the top horizontal height of the positioning plate 402 is higher than the bottom horizontal height of the rotating plate 3, which is convenient for the positioning plate 402 to position the rotating plate 3.

[0034] In this embodiment, the top horizontal height of the guide rod 401 is not higher than the bottom horizontal height of the rotating plate 3, and the guide rod 401 will not affect the normal rotation of the rotating plate 3.

[0035] By providing a positioning component, the positioning plate 402 on the positioning component is attached to the outer surface of the workbench 1. When the socket spring 403 is in the natural elongation state, the horizontal height of the positioning plate 402 is higher than the horizontal height of the upper bottom surface of the rotating plate 3, so that the positioning plate 402 is attached to the outer surface of the rotating plate 3, achieving the effect of positioning the rotating plate 3. When it is necessary to rotate the rotating plate 3, by grasping the handle rod 404 and pressing it down until the horizontal height of the upper surface of the positioning plate 402 is lower than the bottom surface level of the rotating plate 3, the positioning component releases the positioning of the rotating plate 3. After the rotating plate 3 rotates 90°, release the handle rod 404, and the elastic force of the socket spring 403 drives the positioning plate 402 to move upward until the horizontal height of the positioning plate 402 is higher than the bottom surface level of the rotating plate 3, realizing the effect of positioning the rotating plate 3 again. The operation is simple and convenient.

[0036] In this embodiment, the clamping component includes a guide box 5, a spring 501, a slider 502, a rectangular frame 503, an adjusting bolt 504, a clamping plate 505, a handle plate 506, and a slide bar 507. The guide box 5 is fixedly arranged on the upper surface of the rotating plate 3. A spring 501 is fixedly arranged above the guide box 5. The bottom of the spring 501 is fixedly provided with a slider 502. The outer surface of the slider 502 is rotatably provided with a rectangular frame 503 through a pin shaft. The outer end of the rectangular frame 503 is threadedly connected with an adjusting bolt 504. The inner end of the adjusting bolt 504 is rotatably fixed with a clamping plate 505 through a bearing. Handle plates 506 are fixedly arranged at the centers of the left and right side surfaces of the rectangular frame 503. Slide bars 507 are fixedly arranged on the left and right side surfaces of the guide box 5.

[0037] In this embodiment, the guide box 5 is a box structure with an open bottom and outer side. The side surface of the slider 502 is provided with a chute matching the slide bar 507 to ensure the stability of the slider 502 sliding inside the guide box 5.

[0038] In this embodiment, when the spring 501 is in the natural elongation state, the bottom of the slider 502 closely adheres to the upper surface of the rotating plate 3 to ensure that the slider 502 and the rectangular frame 503 closely adhere to the upper surface of the rotating plate 3.

[0039] In this embodiment, when the spring 501 is in the maximum compression state, the height of the slider 502 from the upper surface of the rotating plate 3 is not less than 0.5 times the width of the rectangular frame 503, which is convenient for the rectangular frame 503 to rotate along the slider 502 through the pin shaft.

[0040] By providing a clamping assembly, when clamping the parts of the watch band, place the parts of the watch band between the inner side of the clamping plate 505 and the rectangular frame 503, and then turn the adjusting bolt 504. The adjusting bolt 504 drives the clamping plate 505 to move inward. The clamping plate 505 cooperates with the inner surface of the rectangular frame 503 to clamp and fix the parts of the watch band, ensuring the stability during the processing of the parts of the watch band. When it is necessary to turn over the parts of the watch band for processing, lift the rectangular frame 503 upward by grasping the two handle plates 506, so that the slider 502 moves upward along the guide box 5, and then rotate the rectangular frame 503 along the pin shaft on the slider 502, so that the bottom surface of the rectangular frame 503 faces upward, which is convenient for processing the bottom surface of the parts of the watch band by grinding and polishing. There is no need to take out the parts of the watch band from the clamping assembly to turn over the parts of the watch band for processing, and the operation is simple and convenient.

[0041] The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, without departing from the concept of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent.
