As shown in fig. 1, 5 and 7, an operation opening 121 for communicating the blasting chamber 12 with an external space is opened on a side wall of the machine body 1, and the operation opening 121 is used for providing an operation space for assembling, disassembling and adjusting the spray gun 45. An operation door 122 is hinged to the machine body 1 at the operation opening 121, and the operation door 122 can seal the operation opening 121; the machine body 1 is provided with a travel switch 125 at the edge of the operation opening 121, the travel switch 125 is electrically connected with the sand valve 431, an induction block 1211 for starting the travel switch 125 is fixed at the edge of the operation door 122, and after the induction block 1211 contacts the travel switch 125, the operation door 122 seals the operation opening 121, and the sand blasting can be normally performed. Meanwhile, a sand collecting hopper 123 is integrally formed at the bottom of the sand blasting chamber 12, and the sand collecting hopper 123 is lower than the lower edge of the operation opening 121; fixedly connected with sand discharge pipe 124 on organism 1, sand discharge pipe 124 one end intercommunication is gathered at the bottom of the fill of sand hopper 123, and outside the other end stretched out organism 1, the sand blasting room 12 is discharged to the sand material accessible sand discharge pipe 124 that falls into in gathering sand hopper 123.

As shown in fig. 7 and 8, in this embodiment, the inner wall of the blasting chamber 12 is an iron sheet welded on the machine body 1, one side of the iron sheet facing away from the blasting chamber 12 is an equipment bin 13, the bottom wall of the workpiece placing chamber 11 and the top wall of the blasting chamber 12 are not the same plate, two plates are respectively provided with a hole coaxial with each other, and the two holes jointly form a processing hole 14; and a gap of 4cm is formed between the two plates, a sand sweeping component 5 is arranged in the gap, and the sand sweeping component 5 is used for sweeping sand materials remained on the surface of the implant workpiece 6 subjected to sand blasting. Sweep sand subassembly 5 including sweeping sand piece 51, reset spring 54 and ball 53 of stepping down, sweep sand piece 51 and sand blasting room 12's iron sheet board and slide and be connected, and its sliding direction is perpendicular with the axis of processing hole 14, sweep sand piece 51 and be located the aperture scope of processing hole 14 and this side fixed mounting has brush 52 towards its sliding direction's one side, welded fastening has limit baffle 55 on the iron sheet board of sand blasting room 12, reset spring 54's one end is fixed with the one side that sweeps sand piece 51 deviates from brush 52, the opposite side is fixed with limit baffle 55, ball 53 of stepping down inlays and locates and sweep one side that sand piece 51 deviates from sand blasting room 12 and be located and be close to brush 52 department.

As shown in fig. 3 and 8, an abutment frustum 232 is integrally formed at a position of the jig bar 23 close to the implant workpiece 6, and the abutment frustum 232 is coaxial with the jig bar 23. In the in-process that fixture 3 pushed the anchor clamps stick 23 in the processing hole 14, when planting body work piece 6 was in same height with brush 52, the tip and the planting body work piece 6 contact of brush 52, clamping rod 31 promoted anchor clamps stick 23 and continues to descend, and butt frustum 232 promotes and lets a ball 53, and the sand sweeping block 51 is kept away from anchor clamps stick 23 under the effect of thrust and is removed, reduces the extrusion degree of anchor clamps stick 23 to brush 52 to improve brush 52's life. After the jig bar 23 is returned to the work placing chamber 11, the sand sweeping block 51 is returned by the urging force of the return spring 54.

The implementation principle of the dental implant sand blasting machine provided by the embodiment of the application is as follows:

the respective implant workpieces 6 and the jig bars 23 are fixed first, and all the jig bars 23 are inserted into the placing tray 22, the placing tray 22 is assembled into the machine body 1 from the workpiece placing chamber 11, and then the gripping mechanism 3 is started to operate. The holding rods 31 hold the jig bars 23 one by one to feed the implant workpiece 6 into the blasting chamber 12 through the machining hole 14, the blasting guns 45 blast the implant workpiece 6, and the rotating motor 325 rotates the holding rods 31 to subject the surfaces of the implant workpiece 6 to the blasting. Then the clamping mechanism 3 carries the implant workpiece 6 to leave the sand blasting chamber 12, when the surface of the implant workpiece 6 touches the brush 52, the rotating motor 325 rotates again, so that the brush 52 cleans the surface of the implant workpiece 6; after the treatment is completed, the clamping mechanism 3 returns the clamp bar 23 to its original position. Each time the treatment of four implant workpieces 6 within the same group is completed, the placing tray 22 is rotated by 7.2 ° by the adjustment motor 21 so that the next group of gripper bars 23 and implant workpieces 6 can be caught by the gripping bar 31.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
