[0035] The first driving device 200 is arranged on the movable frame 100;

[0036] The linear motion component 400 is connected between the output end of the first driving device 200 and the movable frame 100, and the first driving device 200 is used to drive the movable frame 100 to move linearly in the first direction;

[0040] 1) In the linear motion assembly 400, the linear motion assembly 400 includes a first guide frame 410, a second guide frame 420, a first roller set 430, a second roller set 440, a first gear 450, a second gear, a third gear 460, and a belt 470; the first guide frame 410 and the second guide frame 420 are respectively arranged on both sides of the movable frame 100; the first roller set 430 is arranged on the movable frame 100 and abuts against the first guide frame 410; the second roller set 440 is arranged on the movable frame 100 and abuts against the second guide frame 420; the first gear 450 is arranged on the movable frame 100 and is located on one side of the first driving device 200; the second gear is arranged on the movable frame 100 and is located on the other side of the first driving device 200; the third gear 460 is installed at the output end of the first driving device 200 and is located above the first gear 450 and the second gear; the belt 470 is sequentially wound under the first gear 450, above the third gear 460, and under the second gear.

One end of the first connecting rod 510 is eccentrically hinged to the turntable. Through the transmission of the second connecting rod 520, the rotating shaft 530 will be driven to rotate, and then the spray gun 600 mounted thereon will be driven to swing reciprocally.

[0044] 3) The advantages of the present utility model are as follows: Through the above structure, the spray gun can have linear motion in the first direction and swinging motion in the second direction, realizing the two-dimensional motion of the spray gun at a relatively low cost, meeting the sandblasting requirements of workpieces, and having very good practicability.
