A spring 10 is fixedly connected to the inner side wall of the connecting sleeve 9. A pressing plate 11 is slidably connected to the inner side wall of the connecting sleeve 9. The top of the pressing plate 11 is fixedly connected to the bottom of the spring 10. An active bayonet 12 is provided on the outer side wall of the connecting sleeve 9. Two first fixing blocks 13 are fixedly connected to the outer side wall of the connecting sleeve 9. Two threaded holes two 27 are provided in the two first fixing blocks 13. Threaded holes one 24 are provided on the left and right sides of the bottom of the support frame 3. The rotating plate 5 is connected to the right threaded hole one 24 through a short rod screw 7. A nut 8 is threadedly sleeved on the outer side wall of the short rod screw 7. A support plate 4 is fixedly connected to the outer side wall of the support frame 3.

The left side wall of the threaded rod 18 is rotatably connected to the outer wall of the left fixing plate 15. A sliding groove is provided on the top of the base 1. A plurality of rolling balls 32 are fixedly connected in the sliding groove. A sliding block is slidably connected in the sliding groove.

The top of the pushing block 16 is fixedly connected to a disc 17. A plurality of fourth threaded holes 33 are provided on the surface of the disc 17. A fixing frame 19 is provided on the outer side wall of the pushing block 16. A plurality of bolts 20 are threadedly connected to the outer wall of the fixing frame 19. The top of the fixing frame 19 is fixedly connected to a limiting plate 21. An activity plate 22 located on the right side of the limiting plate 21 is slidably connected to the top of the fixing frame 19. The outer side wall of the activity plate 22 is connected to the limiting plate 21 through two long rod screws 23. Arc-shaped clamping plates 34 are fixedly connected to the inner side walls of the limiting plate 21 and the activity plate 22. A plurality of rolling balls 32 are evenly arranged in the sliding groove. A plurality of fourth threaded holes 33 are evenly arranged on the surface of the disc 17 and are circular in shape. A plurality of bolts 20 are evenly arranged on the four sides of the fixing frame 19. The length and width of the inner side of the fixing frame 19 are greater than the length and width of the pushing block 16. Different fixtures can be used according to different castings. First, the pushing block 16 is moved along the threaded rod 18 to the directly below the first motor 6 by the second motor 14. Subsequently, the corresponding screws penetrate through the openings of the casting and are connected to the fourth threaded holes 33, so as to be fixed on the surface of the disc 17. If the casting has no opening, the fixing frame 19 is sleeved on the pushing block 16, and then a plurality of bolts 20 are rotated to make them contact with the outer side of the pushing block 16. When turned to the limit, the fixing frame 19 is connected to the pushing block 16. At this time, the casting is placed on the top of the fixing frame 19.

When the arc-shaped clamping plate 34 contacts the casting, the long rod screw 23 is rotated to the limit to complete the fixing of the casting, thereby improving the practicability of the device fixture.

[0025] The working principle of the present invention is as follows:

[0026] When the device needs to replace the casting head, remove the screws fixing the first fixing block 13 and the second fixing block 30, then pick up the clamping post 28, move it upward and rotate it, so that the convex rod 29 moves downward along the movable bayonet 12 and disengages from the connecting sleeve 9. Then pick up the required grinding block 25 or drill bit 26, insert the clamping post 28 into the connecting sleeve 9, and make the convex rod 29 move upward along the movable bayonet 12 and rotate. At this time, the spring 10 is in a compressed state. When it is moved to the top of the movable bayonet 12 and released, the spring 10 will be in a stretched state and drive the pressing plate 11 to move vertically downward, so that the convex rod 29 is clamped in the movable bayonet 12, and the spring 10 continuously exerts an elastic force on the pressing plate 11 to fix the clamping post 28. Then use the screws of the corresponding model to rotate into the third threaded hole 31 and the second threaded hole 27 to fix the first fixing block 13 and the second fixing block 30, thus completing the replacement and installation operation, saving a lot of time for replacing the device, thereby improving the manufacturing work efficiency. And the operator can also make the nut 8 and the short rod screw 7 fall off by twisting, then rotate the rotating plate 5 to change the working position of the device, and then fix the rotating plate 5 through the nut 8 and the short rod screw 7. Subsequently, the installed grinding block 25 or drill bit 26 can be rotated by the first motor 6 to perform drilling and grinding operations;

[0027] Different fixtures can also be used according to different castings. First, make the pushing block 16 move along the threaded rod 18 to directly below the first motor 6 through the second motor 14. Then, pass the corresponding screws through the openings of the casting and connect them to the fourth threaded hole 33 to fix them on the surface of the disc 17. If the casting has no opening, put the fixing frame 19 on the pushing block 16, and then rotate a plurality of bolts 20 to make them contact the outside of the pushing block 16. When twisted to the limit, the fixing frame 19 is connected to the pushing block 16. At this time, place the casting on the top of the fixing frame 19, and make the movable plate 22 move vertically to the left by rotating the long rod screw 23. When the arc-shaped clamping plate 34 contacts the casting, the long rod screw 23 is rotated to the limit to complete the fixing of the casting, thereby improving the practicability of the device fixture.

[0028] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
