[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-4This utility model discloses a positioning mechanism for an automotive clamp, comprising a worktable 1, with a mounting plate 3 fixedly connected to one side of the top of the worktable 1. The mounting plate 3 facilitates the reliable operation of the electric push cylinder 2, preventing malfunctions caused by insecure installation. The electric push cylinder 2 is mounted on the mounting plate 3, enabling automated pushing operations, improving work efficiency, and providing stable and precise pushing force. A connecting plate 4 is provided at the output end of the electric push cylinder 2, ensuring a tight connection between the electric push cylinder 2 and the main push plate 5, allowing the main push plate 5 to accurately respond to the actions of the electric push cylinder 2. One end of the connecting plate 4 is fixed to the main push plate 5 by bolts. The main push plate 5 can drive the driven push plates 9 to work together to achieve the positioning and clamping of the automobile workpiece. Three driven push plates 9 are distributed around the main push plate 5. The driven push plates 9 can facilitate the all-round positioning and fixation of the automobile workpiece, ensuring the accurate position of the workpiece during processing. A synchronization component is provided on one side of the main push plate 5. Four support columns are distributed on the worktable 1. The top of the four support columns is provided with a bearing plate 6. The bearing plate 6 can make the workpiece stable on the positioning mechanism, which is convenient for processing operations.

[0020] In this invention, the main push plate 5 is convex, and a first connecting shaft 7 is fixedly connected to one side of the main push plate 5. A support plate is welded to the first connecting shaft 7. The first connecting shaft 7 facilitates the accurate transmission of the movement of the main push plate 5 to the rotating disk 8, causing the rotating disk 8 to rotate. Three slave push plates 9 are L-shaped, and a second connecting shaft is fixedly connected to one side of the slave push plate 9. A support plate is welded to the second connecting shaft. The synchronization component includes a rotating disk 8 located on one side of the main push plate 5. The rotating disk 8 has four arc-shaped grooves equidistantly opened on it. One first connecting shaft 7 and three second connecting shafts are slidably fitted into the arc-shaped grooves respectively. The support plate abuts against the bottom of the rotating disk 8. The rotating disk 8 facilitates the rotation of the three slave push plates 9. The slave pusher plate 9 can move synchronously with the main pusher plate 5 to achieve multi-directional positioning and clamping of the automotive workpiece. Both the main pusher plate 5 and the slave pusher plate 9 have threaded posts 12 welded to their top surfaces. A limiting plate 11 for restricting the vertical movement of the workpiece is bolted to the threaded post 12. The limiting plate 11 has a knob cap, allowing it to be securely installed on the main pusher plate 5 and the slave pusher plate 9, thus limiting vertical movement. Both the main pusher plate 5 and the slave pusher plate 9 have a clamp 10 at one end, and bolts for fixing the clamp 10 are threaded to the other end, facilitating the replacement of the clamp 10 according to the shape to be processed.

[0021] Working Principle: In use of this invention, the car to be processed is first placed on the support plate 6, which is supported by four support columns above the worktable 1, providing a stable support plane for the to be processed. Then, the electric push cylinder 2 is activated. The electric push cylinder 2 is fixed on the mounting plate 3, which is fixed to one side of the worktable 1. The output end of the electric push cylinder 2 extends and pushes the main push plate 5 through the connecting plate 4. The first connecting shaft 7 on one side of the main push plate 5 slides in the arc groove of the rotating disk 8 as the main push plate 5 moves linearly. Due to the guiding effect of the arc groove on the rotating disk 8 and the connection between the first connecting shaft 7 and the support plate, the linear movement of the main push plate 5 causes the rotating disk 8 to rotate. During the rotation of the rotating disk 8, the second connecting shafts in the other three arc grooves are driven to move. The second connecting shafts are connected to the slave push plates 9, thereby realizing the synchronous linkage between the slave push plates 9 and the main push plate 5. In this way, the main push plate 5 and the three The pusher plate 9 approaches the workpiece from multiple directions simultaneously, achieving horizontal positioning and clamping. After the main pusher plate 5 and the pusher plate 9 are in position, the knob on the limiting plate 11 is rotated, causing the limiting plate 11 to move downwards along the threaded post 12 until it contacts the workpiece, restricting its vertical movement and completing omnidirectional positioning and clamping. After processing, the knob on the limiting plate 11 is rotated in the opposite direction, causing the limiting plate 11 to move upwards along the threaded post 12, releasing the vertical restriction on the workpiece. Then, the output end of the electric pusher cylinder 2 retracts, driving the main pusher plate 5 to move in the opposite direction. The reverse movement of the main pusher plate 5, through the linkage of the first connecting shaft 7, the rotating disk 8, and the second connecting shaft, causes the pusher plate 9 to move in the opposite direction synchronously, releasing the horizontal clamping of the workpiece and completing one positioning operation cycle. The positioning work of the next workpiece can then be performed. This concludes the use of the positioning mechanism for the automotive fixture.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
