Using fixed hydraulic fixtures for machining can ensure machining accuracy, improve production efficiency, handle complex workpieces, reduce labor intensity, and ensure machining stability. However, traditional fixed hydraulic fixtures for machining lack flexibility, have high maintenance costs, limited response speed, and pose certain safety risks. In order to meet the requirements of modern machining, new types of fixed hydraulic fixtures for machining are used.
[0003] In the existing technology, traditional automatic clamping devices usually involve multiple independent and complex steps. From positioning to clamping, the connection between each link is not smooth, resulting in a long overall clamping time and greatly limiting the efficiency of machining. Utility Model Content

Detailed Implementation
[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0025] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a fixed hydraulic clamp for machining, comprising a base plate 1, a hydraulic rod 11 fixedly connected to the upper surface of the base plate 1, a bracket 12 fixedly mounted at the output end of the hydraulic rod 11, a connecting block 13 rotatably connected to the inner wall of the bracket 12, a bearing plate 14 fixedly connected to the upper surface of the connecting block 13, a rotating rod 15 rotatably connected to the outer wall of the bearing plate 14, a rotating shaft 16 rotatably connected to the inner wall of the rotating rod 15, a sliding block 17 fixedly connected to the rear outer wall of the rotating shaft 16, and a sliding block 17 slidably connected to the bearing plate 14. A sleeve 18 is slidably connected to the inner wall of the plate 14 and the outer wall of the sliding block 17. The outer wall of the sleeve 18 is fixedly connected to the inner wall of the base plate 1. A clamping block 19 is fixedly connected to the outer wall of the sliding block 17. A flipping assembly is provided on the upper surface of the base plate 1. The flipping assembly includes a flipping rod 2. The lower surface of the flipping rod 2 is fixedly connected to the upper surface of the base plate 1. A limit rod 21 is fixedly connected to the upper surface of the base plate 1. A spring 22 is provided on the outer wall of the limit rod 21. The lower end of the spring 22 is provided on the upper surface of the base plate 1. The upper end of the spring 22 is slidably connected to the lower surface of the bearing plate 14.
[0026] Specifically, by activating the hydraulic rod 11 on the base plate 1, the support 12 is moved, causing the connecting block 13 to drive the bearing plate 14 to move upward. The bearing plate 14 drives the rotating rod 15 to rotate, causing the rotating shaft 16 to move. The rotating shaft 16 will drive the sliding block 17 to slide stably on the inner wall of the sleeve 18. The movement of the sliding block 17 will drive the clamping block 19 to move synchronously, thereby achieving the effect of quickly clamping the workpiece and improving the machining efficiency. The flipping rod 2 set on the upper surface of the base plate 1 can make the bearing plate 14 fall and flip at the same time to achieve the effect of dumping the debris. At the same time, the limiting rod 21 can limit the flipping angle of the bearing plate 14. By setting the spring 22, the bearing plate 14 can be returned to its original position.
[0027] Reference Figure 1 and Figure 3 A rotating column 3 is rotatably connected to the upper surface of the base plate 1, and a nozzle 31 is fixedly connected to the upper surface of the rotating column 3; a second spring 32 is provided on the outer wall of the rotating column 3, the lower end of the second spring 32 is fixedly connected to the upper surface of the base plate 1, and the upper end of the second spring 32 is provided on the lower surface of the rotating block 33.
[0028] Specifically, when the support plate 14 descends, the pressing block 37 fixed on the support plate 14 moves synchronously with the support plate 14, thereby pressing down the connecting plate 36. As a result, the connecting plate 36 drives the rotating block 33 to move. Since the pressing down of the rotating block 33 causes the spring 32 to undergo elastic deformation, it can provide power for the rotating block 33 to return to its original position.
[0029] Reference Figure 1 , Figure 4 and Figure 5 The inner wall of the rotating block 33 is provided with a sliding groove 34, which is used to rotate the rotating column 3; the inner wall of the rotating block 33 is slidably connected to a driving block 35, the outer wall of the driving block 35 is slidably connected to the inside of the sliding groove 34, and the outer wall of the driving block 35 is fixedly connected to the outer wall of the rotating column 3; the outer wall of the rotating block 33 is fixedly connected to a connecting plate 36, the upper surface of the connecting plate 36 is fixedly connected to a lower pressing block 37, and the lower surface of the lower pressing block 37 is slidably connected to the upper surface of the bearing plate 14.
[0030] Specifically, by opening a groove 34 on the inner wall of the rotating block 33, when the rotating block 33 moves, the drive block 35 fixed on the rotating column 3 will slide stably inside the groove 34, thereby enabling the rotating column 3 to rotate. The rotation of the rotating column 3 will cause the nozzle 31 fixed on the upper surface of the rotating column 3 to rotate, thereby achieving the effect of cleaning the debris remaining on the upper surface of the bearing plate 14, while also achieving the effect of not affecting the machining.
[0031] Working principle: When the device is needed, after placing the workpiece on the support plate 14, the hydraulic rod 11 fixed on the base plate 1 is activated to push the bracket 12 to move, causing the connecting block 13 to move synchronously. The movement of the connecting block 13 drives the support plate 14 to move upward, causing the rotating rod 15 rotating on the outer wall of the support plate 14 to rotate. The rotation of the rotating rod 15 drives the rotating shaft 16 to move, thereby causing the sliding block 17 to slide stably on the inner wall of the sleeve 18. The movement of the sliding block 17 further causes the clamping block 19 to move, achieving the effect of automatically clamping the workpiece. After processing is completed, the support plate 14 is driven downward by the hydraulic rod 11 to release the workpiece. After the workpiece is removed, the hydraulic rod 11 continues to drive the support plate 14 downward. The flipping rod 2 fixed on the base plate 1 pushes the support plate 14 to rotate under the action of the bracket 12 and the connecting block 13, compressing the support plate 14. Spring 22 provides power for the return of the bearing plate 14. The limiting rod 21 can limit the rotation angle of the bearing plate 14. When the bearing plate 14 moves, it will drive the pressing block 37 to move down at the same time, thereby pressing down the connecting plate 36. The movement of the connecting plate 36 will drive the rotating block 33 to move down at the same time, thereby compressing the spring 32 and causing it to deform. When the rotating block 33 moves, the rotating block 33 set on its inner wall will slide on the inner wall of the slide groove 34 due to the driving block 35 fixed on it, causing the rotating column 3 to rotate synchronously, thereby rotating the nozzle 31 to the top of the bearing plate 14 to wash away the residual debris on the bearing plate 14. This fixture can achieve the effect of quickly clamping the workpiece and improving the machining efficiency, and can also facilitate the washing of debris on the bearing plate 14 without affecting the machining effect of the workpiece.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
