[0019] As shown in the attached Figure 1 to the attached Figure 3 figures:

[0020] An irregular casting clamping device for casting production provided by the present utility model includes a base 1, a fixed clamping table 2, a moving clamping table 3, a ball slide 4, a ball screw 5 and a handle 6. The fixed clamping table 2 is fixedly installed on the base 1, and the moving clamping table 3 is slidably installed. Among them, the fixed clamping table 2 and the moving clamping table 3 have the same structure. In addition, the moving clamping table 3 is fixed to the ball slide 4. The ball slide 4 is slidably installed with the base 1 and is installed on the ball screw 5 rotatably installed on the base 1. Handles 6 are installed at any end of the ball screw 5, on the fixed clamping table 2 and on the moving clamping table 3, and three handles 6 are provided.

[0021] Specifically, the fixed clamping table 2 includes a clamping table 21, a support frame 22, a downward pressing lead screw 23, a downward pressing locking plate 24, a clamping head 25, a sliding convex 26, a leveling plate 27, a spring 28, a sliding shaft 29 and a pushing plate 20. The support frame 22 is fixedly installed on the clamping table 21. The lower end of the downward pressing lead screw 23 installed on the support frame 22 is rotationally connected to the downward pressing locking plate 24, and the downward pressing locking plate 24 is slidably connected to the support frame 22. The clamping head 25 is slidably connected to the clamping table 21 through the sliding convex 26 provided thereon. The clamping table 21 is elastically connected to the leveling plate 27 through the spring 28. The sliding shaft 29 fixedly installed on the pushing plate 20 slidably passes through the clamping table 21 and is fixed to the leveling plate 27.

[0022] Specifically, the clamping table 21 of the fixed clamping table 2 is fixed to the base 1, while the clamping table 21 of the moving clamping table 3 is fixed to the ball slide 4 and is slidably connected to the base 1.

[0023] Furthermore, the vertical cross-section of the clamping table 21 is ingeniously designed as a lateral "U" - shaped structure. This design not only enhances the stability of the clamping table 21 but also provides sufficient space for its internal components. Above the middle of the clamping table 21, a rectangular notch is specifically provided. It is located directly below the downward pressing locking plate 24, allowing the downward pressing locking plate 24 to smoothly pass through the notch when needed, thereby achieving the locking and releasing of the lower clamping head 25.

[0024] Furthermore, the clamping heads 25 are key components on the clamping table 21 and are designed to be able to move independently horizontally. This means that each clamping head 25 can be fine-tuned according to the shape and size of the casting to adapt to different clamping requirements. These clamping heads 25 are all located below the downward pressing locking plate 24. When the downward pressing locking plate 24 descends, it interacts with the clamping heads 25 to firmly lock them in place, ensuring that the casting does not move during processing or inspection. In addition, to ensure the smooth movement of the clamping heads, sliding grooves matching the sliding convexes 26 of the clamping heads are provided on the inner wall of the clamping table 21. These sliding grooves provide precise guidance and stable support for the clamping heads 25.

[0025] Furthermore, the leveling plate 27 plays an important role in the clamping device. It is located at one side of one end of several clamping heads 25 and inside the clamping table 21. The presence of the leveling plate 27 helps to keep the clamping heads 25 neat during the return movement, preventing them from being misaligned or tilted. Through holes allowing the sliding shafts 29 to slide through are also provided on the clamping table 21. These sliding shafts 29 not only provide stable support for the leveling plate 27 but also allow it to be fine-tuned as needed. It should be noted that the number of sliding shafts 29 is two, and each sliding shaft 29 is ingeniously designed at its inner position to ensure the best mechanical properties and stability.

[0026] The working principle is as follows: First, when it is necessary to clamp an irregular casting, the operator first ensures that the fixed clamping table 2 is firmly installed on the base 1. At this time, the moving clamping table 3 is slidably connected to the base 1 through the ball slide 4 and is installed on the ball screw 5, being in the initial position. Three handles 6 are respectively installed at both ends of the ball screw 5 and on the moving clamping table 3, ready for position adjustment.

[0027] Then, the operator rotates the handle 6 installed at either end of the ball screw 5. By using the transmission principle of the ball screw 5, the operator drives the ball slide 4 to slide on the base 1, and then drives the moving clamping table 3 to approach the fixed clamping table 2. During this process, the operator can flexibly adjust the position of the moving clamping table 3 according to the size and shape of the casting, making the distance between it and the fixed clamping table 2 appropriate to prepare for clamping the casting.

[0028] Next, as the clamping heads 25 of the moving clamping table 3 and the fixed clamping table 2 come into contact with the casting, several clamping heads 25 will undergo lateral movement to varying degrees to fit the shape of the casting, thereby realizing the positioning and restriction of the casting. Subsequently, the operator starts to operate the clamping mechanisms on the fixed clamping table 2 and the moving clamping table 3. In the fixed clamping table 2 and the moving clamping table 3, the operator rotates the handle 6 of the downward pressure screw 23, causing the downward pressure screw 23 to rotate and push the downward pressure locking plate 24 to move downward. The downward pressure locking plate 24 passes through the rectangular notch on the clamping table 21 and interacts with the clamping head 25 below to lock the clamping head 25, thereby clamping the casting.

[0029] Finally, when the machining or inspection of the casting is completed, the operator rotates the handle of the ball screw 5 again to move the moving clamping table 3 away from the fixed clamping table 2 to release the casting. Subsequently, the push plate 20 is pushed. The push plate 20 drives the alignment plate 27 through the sliding shaft 29, thereby neatly aligning several locking heads 25. When the push plate 20 is released, the spring 28 drives the alignment plate 27 to reset. During the positioning and restriction process of the clamping head 25, it may come into contact with the surface of the alignment plate 27, and the spring 28 is used to buffer the impact force after the contact of the two. The entire clamping device can realize the rapid clamping and release of the casting through simple operations, greatly improving the production efficiency and machining accuracy.

[0030] Using the technical solution of the present utility model, or those skilled in the art being inspired by the technical solution of the present utility model to design a similar technical solution and achieving the above technical effects shall fall within the protection scope of the present utility model.
