A moving block 9 and a pushing component for horizontally moving the moving block 9 are integrated on the top of the fixed block 5. A locking pressure plate 11 and a limiting component for limiting the position of the locking pressure plate 11 are integrated on the outer side of the vertical rod 12. A crank screw 7 and a positioning screw 8 are screwed together on the outer wall of the adjusting screw fixing seat 4, and steel ball positioning heads 10 are provided on the opposite surfaces of the adjusting screw fixing seat 4 and the moving block 9;

[0025] The adjusting screw fixing seat 4 and the moving block 9 are each provided with two sets of screws and steel ball positioning heads 10 that are screwed together, so that each steel ball positioning head 10 can be adjusted independently. First, the four sets of steel ball positioning heads 10 are adjusted to the specified position accordingly, and the crank screw 7 and the positioning screw 8 on the adjusting screw fixing seat 4 are also independently adjusted to the specified shape according to the outer contour of the casting. The casting is placed on the workpiece base plate 13, and one side of the workpiece abuts the two sets of steel ball positioning heads 10, the crank screw 7 and the positioning screw 8. Then, the locking pressure plate 11 cover is pressed to the positioning of the casting through the cooperation of the vertical rod 12 and the nut 15. Finally, the moving block 9 is moved by rotating the push rod 6 until the two sets of steel ball positioning heads 10 on the moving block 9 abut against the outer wall of the casting, thereby achieving stable positioning of the casting. The independently adjustable positioning screw 8, the crank screw 7 and the four sets of steel ball positioning heads 10 can adapt to the irregular contour of the outer side of the casting, thereby improving the applicability of the casting processing jig.

[0026] Specifically, such as Figure 2 and Figure 4 As shown, the outer wall of the vertical rod 12 is provided with two groups of thread grooves, and the top of the tooling fixing plate 1 is fixedly connected with a nut 2 16, which is screwed together with one group of the two thread grooves. The limiting assembly includes a nut 15, which is screwed together with the other group of the two thread grooves.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, the top of the workpiece base plate 13 is designed to avoid air. The casting is uneven, and the less surface contact, the easier it is to adjust. Therefore, an avoidance design is adopted. Multiple sets of clamping fixtures 2 include fixing screws 3 screwed together with the fixture fixing plate 1, which are used to lock the base plate. The adjusting screw fixing seat 4 and the opposite surface of the moving block 9 are fixedly connected with screws, and the steel ball positioning head 10 is screwed together with the screw so that multiple sets of steel ball positioning heads 10 can be adjusted independently.

[0028] Working principle: The adjusting screw fixing seat 4 and the moving block 9 are each provided with two sets of screws and steel ball positioning heads 10 that are screwed together, so that each steel ball positioning head 10 can be adjusted independently. First, adjust the four sets of steel ball positioning heads 10 to the specified position accordingly. Then, independently adjust the crank screw 7 and the positioning screw 8 on the adjusting screw fixing seat 4 to the specified shape according to the external contour of the casting. Place the casting on the workpiece base plate 13, and make one side of the workpiece contact the two sets of steel ball positioning heads 10, the crank screw 7 and the positioning screw 8. Then, press the locking pressure plate 11 cover to the positioning of the casting through the cooperation of the vertical rod 12 and the nut 15. Finally, push the locking plate 11 cover to the positioning of the casting by rotating the push rod 12. The movable rod 6 moves the movable block 9 until the two groups of steel ball positioning heads 10 on the movable block 9 abut against the outer wall of the casting, thereby achieving stable positioning of the casting. The independently adjustable positioning screw 8, crank screw 7 and four groups of steel ball positioning heads 10 can adapt to the irregular contour of the outer side of the casting, thereby improving the applicability of the casting processing jig. The outer wall of the vertical rod 12 is provided with two groups of threads, one group of threads cooperates with nut 15 to realize the combination of locking the pressure plate 11 and the casting, and nut 2 16 is fixed to the top of the workpiece fixing plate 1.
