[0002] A jig is a tool or device used for fixing, positioning, measuring, and protecting workpieces in processes such as production, testing, and assembly. It is usually made of materials such as metal and plastic, and has a specific shape, size, and function, which can improve production efficiency, reduce losses, and quality risks. The so-called positioning jig is a fixture that can position your product at a specific position.

[0003] In Chinese Patent No. 202222273378.1, a positioning jig provided by the utility model includes a base and a positioning card plate detachably installed on the base. An inwardly concave placement groove is provided on the base, and the placement groove penetrates through the front and rear ends of the base. The positioning card plate is installed in the placement groove. A number of card slots with the same structure and an open structure are equidistantly arranged on one side of the positioning card plate, and the card slots penetrate through the upper and lower ends of the positioning card plate. The width of the positioning card plate is smaller than the width of the base. The positioning jig of this application has a simple structure and low processing cost. The several strip-shaped rubber strip materials to be bonded are respectively separated and positioned in the card slots for bonding, which improves the bonding accuracy and efficiency of the product and ensures the stable quality of product processing.

[0004] The existing adjusting mechanism and positioning jig have the problem that after the positioning jig clamps and fixes the workpiece to be processed, the angle cannot be adjusted. If the processing worker needs to perform processing operations on different surfaces of the workpiece, the worker himself has to move around the workpiece.

And there are multiple U-shaped bayonets 207, which cooperate with the adjusting handle 204 to facilitate the limit fixation after rotating and adjusting to the appropriate position.

[0029] Embodiment 2

[0030] Please refer to Figure 1 As shown in the figure, there is a positioning jig of an adjusting mechanism and a positioning jig, including the adjusting mechanism according to any one of claims 1-3, and a positioning jig bottom board 1 arranged at the bottom of the angle adjusting component 2. Installation screw holes 3 are opened on the side of the positioning jig bottom board 1. A positioning jig table board 4 is installed at the top of the angle adjusting component 2. An adjusting sliding groove 5 is opened inside the positioning jig table board 4. A clamping component 6 is installed at the top of the positioning jig table board 4. And a clamp block adjusting component 7 is installed on the back of the clamping component 6.

[0031] Please refer to Figure 4 As shown in the figure, there is a positioning jig of an adjusting mechanism and a positioning jig. The clamping component 6 is used for clamping and fixing the processed parts suitable for uneven end faces. The clamping threaded rods 603 are arranged at equal intervals inside the positioning clamp block 601. And the positioning clamp block 601 forms a sliding structure with the positioning jig table board 4 through the limit sliding block 602 and the adjusting sliding groove 5. And the shape of the limit sliding block 602 is set as an inverted "T" shape. A number of clamping threaded rods 603 are arranged at equal intervals on the positioning clamp block 601. And through rotation adjustment, the anti-slip silicone balls 604 at the ends of the clamping threaded rods 603 can extend to different length positions, so as to facilitate the clamping and fixing of the processed parts with end faces not in the same plane. And each clamping threaded rod 603 can be flexibly adjusted to facilitate the adaptation to processed parts of different shapes.

[0032] Please refer to Figure 5As shown, a positioning fixture of an adjustment mechanism and a positioning fixture, the clamp block adjustment component 7 includes a fixed block 701, and the internal thread connection of the fixed block 701 is connected to a pushing threaded rod 702, and the end of the pushing threaded rod 702 is integrally connected to an anti-rotation block 703, and the external rotation of the anti-rotation block 703 is connected to an anti-rotation ring 704, the pushing threaded rod 702 forms a rotating structure with the anti-rotation ring 704 through the anti-rotation block 703, and the anti-rotation ring 704 and the positioning clamp block 601 are fixedly connected, by twisting the pushing threaded rod 702, the clamping component 6 can be pushed to slide and change its position, so that it can be clamped and fixed close to the workpiece, and it can adapt to workpieces of different sizes, and an anti-rotation block 703 that can rotate inside the anti-rotation ring 704 is provided, when the pushing threaded rod 702 rotates, the positioning clamp block 601 will not rotate accordingly.

[0033] Working principle: First, this positioning fixture can be installed and fixed on the processing operation table by inserting screws into the mounting screw holes 3 and screwing them into the processing lathe. When a certain workpiece needs to be fixed and then processed, it is only necessary to place the workpiece to be processed on the positioning fixture table 4, and then screw and push the threaded rod 702. The pushing threaded rod 702 will also cause the anti-rotation block 703 to rotate inside the anti-rotation ring 704. Since the threaded rod 702 and the fixed block 701 are threadedly connected, when the threaded rod 702 is screwed, its end will push the positioning clamp 601 to slide on the positioning fixture table 4 until the anti-rotation ring 703 on the side of the positioning fixture table 4 is locked. The non-slip silicone balls 604 contact the workpiece to be processed. If the end surface of the workpiece is relatively flat, the non-slip silicone balls 604 with the same original extended length can be directly used to clamp and fix it. If the end surface of the workpiece is uneven, the non-slip silicone balls 604 that have not yet contacted the end surface of the workpiece can be turned with their corresponding rotating knobs 605. The rotation of the rotating knob 605 causes the clamping threaded rod 603 to rotate inside the positioning clamp block 601, thereby pushing the non-slip silicone balls 604 at the end thereof to tightly press against the end surface of the workpiece. By using the interaction of the clamping components 6 on both sides of the workpiece, the workpiece can be clamped and fixed on the positioning fixture table 4.

[0034] During the processing, if one side needs to be processed after processing, the adjusting handle 204 only needs to be turned upward to release the adjusting handle 204 from the restriction of the U-shaped bayonet 207, and then the angle adjustment turntable 202 can be rotated, and the positioning fixture table 4 on the top and the workpiece after clamping and fixing can be rotated and adjusted together. When the other side of the workpiece that needs to be processed is aligned with the operator, the adjusting handle 204 is turned downward and clamped into the U-shaped bayonet 207 at the corresponding position. At this time, the first magnet 205 at the bottom of the adjusting handle 204 is also just adsorbed on the second magnet 206 inside the U-shaped bayonet 207 for fixation.

[0035] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed.
