DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely examples. The present invention is not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] Reference Figure 1-Figure 3 The present invention provides a surface polishing device for precision die-castings, comprising a base plate 1 and an air polishing machine 7. A die-casting body 3 is provided on the upper surface of the base plate 1. Two toolings 4 are provided on the upper surface of the base plate 1. The tooling 4 comprises a fixing plate 10. The bottom of the fixing plate 10 is fixed with two pins 16 by bolts. Guide holes 14 are provided at both ends of the fixing plate 10. A guide column 18 is slidably connected in the guide hole 14. A clamping plate 12 is fixed between the two guide columns 18 by bolts. The guide column 18 can guide the clamping plate 12 so that it can move stably. A threaded rod 11 is rotatably connected to one side of the clamping plate 12, and the threaded rod 11 is threadedly connected to the fixing plate 10. The top of the base plate 1 There are multiple bottom holes 2 on the bottom, and the pins 16 are plugged into the bottom holes 2 corresponding to their positions. The staff adjusts the positions of the two toolings 4 on the base plate 1 and the distance between the two toolings 4 according to the size of the die-casting body 3, and places the two toolings 4 on the base plate 1 respectively, so that the pins 16 are inserted into the bottom holes 2 at the corresponding positions, and then the die-casting body 3 is placed on the base plate 1 so that the die-casting body 3 is located between the two toolings 4, and then the threaded rod 11 is rotated to drive the splint 12 to move until the splint 12 is in close contact with the side of the die-casting body 3, thereby positioning the die-casting body 3, and then the staff takes the air polishing machine 7 to polish the surface of the die-casting body 3.

[0023] In the present invention, it should be noted that a side plate 5 is fixed to one side of the bottom plate 1 by bolts, and a plurality of side holes 6 are opened inside the side plate 5. A cavity 8 is opened inside the side plate 5 and the bottom plate 1. The waste chips and impurities generated when processing the die-casting body 3 enter the cavity 8 of the bottom plate 1 and the side plate 5 through the bottom hole 2 and the side hole 6. A dust hood 9 is fixed to one side of the bottom plate 1, and the dust hood 9 is fixed to the bottom of the side plate 5.
