[0023] Example 1
[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution adopted by this utility model is as follows: This solution provides a clamping fixture for die casting processing, including a processing frame 1, an adjusting table 2, an adjusting frame 3, and a workpiece fixing fixture 4. The lower end of the adjusting table 2 is provided with a rotating shaft 5. The adjusting table 2 is rotatably disposed in the processing frame 1 through the rotating shaft 5. The processing frame 1 is provided with guide grooves 6 on both sides. The adjusting frame 3 is symmetrically slidably installed at both ends of the processing frame 1 through the guide grooves 6. The workpiece fixing fixture 4 is detachably installed on the adjusting frame 3 and located above the adjusting table 2. The adjusting table 2 is used to place the die casting, and the adjusting frame 3 is used to adjust the workpiece fixing fixture 4 to complete the clamping and fixing of the die casting. A threaded adjusting rod 7 is threadedly connected to the middle of one side of the adjusting frame 3. One end of the threaded adjusting rod 7 is rotatably connected to the outer wall of the processing frame 1, and the other end of the threaded adjusting rod 7 is provided with a crank handle 8. Turning the crank handle 8 drives the adjusting frame 3 to move laterally, thereby causing the workpiece fixing fixture 4 to move laterally and clamp and fix the die casting. The adjusting frame 3 is located inside the processing frame 1 and has a positioning rod 9 at one end. The workpiece fixing fixture 4 is equipped with a positioning sleeve 10 that matches the positioning rod 9 at the rear end. The positioning sleeve 10 can be detachably installed on the positioning rod 9 by a hand-tightening bolt 11. The workpiece fixing fixture 4 adopts a modular design and includes multiple sets of fixtures with different shapes and sizes. Each set of workpiece fixing fixtures 4 is matched with different die-cast parts, and each pair of workpiece fixing fixtures 4 cooperates with each other to clamp and fix the die-cast parts.
[0025] Place the die-cast part on the adjustment table 2, and screw on the threaded adjustment rods 7 located on both sides of the processing frame 1. The threaded adjustment rods 7 then drive the adjustment frame 3 to move, and the die-cast part is clamped and fixed by the workpiece fixing fixture 4 installed on the positioning rod 9. When it is necessary to clamp and fix the die-cast part according to the usage requirements, the positioning sleeve 10 can be removed from the positioning rod 9 by screwing on the hand-tightening bolt 11, so as to install the matching workpiece fixing fixture 4 as needed and improve the fixing effect.
[0026] Example 2
[0027] Based on Example 1, in order to facilitate flexible adjustment of the clamping position of the die-casting part, such as Figure 1 and Figure 3 As shown, the adjustment table 2 is a disc-shaped structure with an angle scale line 16 on it. The processing frame 1 is equipped with a matching pointer 17 to facilitate precise indication of the adjustment angle. A forward and reverse motor 12 is installed on one side of the bottom of the processing frame 1. The output shaft of the forward and reverse motor 12 is equipped with a drive gear 13.

A lamp holder 15 for installing lighting lamps is installed on the top of the processing frame 1.
[0028] The forward and reverse motor 12 is started, and the adjustment table 2 is driven to rotate through the meshing of the drive gear 13 and the driven gear 14. This allows for the adjustment of the processing or clamping position of the die-casting part placed on the adjustment table 2. The adjustment range can be observed in real time through the cooperation of the pointer 17 and the scale line 16. The lamp holder 15 facilitates the installation of lighting equipment, providing good working lighting and further improving processing accuracy and convenience.
