For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0026] In one embodiment of the present utility model, as Figures 1 to 7 shown, there is provided a sandblasting jig that can be automatically flipped, including a conveyor belt 10 and a sandblasting machine 101 provided at the end of the conveyor belt 10. It further includes a fixed frame 102. Four corners of the fixed frame 102 are respectively provided with a support column 103. A flipping mechanism 1 is provided at the head end of the conveyor belt 10. The flipping mechanism 1 includes a double-shaft motor 11 and two fixed jigs 12. Two output shafts of the double-shaft motor 11 are respectively connected with a connecting rod 13. Rotating shafts are provided at the ends of the two connecting rods 13 far away from the double-shaft motor 11. Driving parts are provided on the two rotating shafts. The two rotating shafts are respectively connected with a fixed jig 12. The two fixed jigs 12 include a fixed part 130 and a movable part 14. A first clamping jaw 2 is provided at the head end of the fixed part 130. A driving motor 131 is provided outside the fixed part 130. A driving wheel 132 and a sliding part 15 are provided inside the fixed part 130. The driving wheel 132 is connected to the output shaft of the driving motor 131. A rack 151 is provided on one side of the sliding part 15, and a guide rod 152 is provided on the other side. A connecting part 153 is provided at the head end of the sliding part 15. The connecting part 153 slidably passes through the side wall of the fixed part 130 and is fixedly connected with the movable part 14. A second clamping jaw 3 is provided on the movable part 14. The first clamping jaw 2 and the second clamping jaw 3 cooperate to clamp the fixed frame 102.

[0027] Further, the driving part is a rotary motor 4, and the output shaft of the rotary motor 4 is fixedly installed on the rotating shaft. Specifically, when in use, the product is placed in the fixed frame 102 and conveyed into the sandblasting machine 101 through the conveyor belt 10 to sandblast one side of the product. After completion, the fixed frame 102 is conveyed out by the conveyor belt 10 and captured by the flipping mechanism 1. During this process, the double-shaft motor 11 drives the connecting rod 13 to swing horizontally, and the fixed fixture 12 moves towards the direction close to the fixed frame 102. In order to keep the posture of the fixed fixture 12 horizontal, the rotating shaft is driven to rotate by the rotary motor 4, and its rotation angle is the same as that of the connecting rod 13. Finally, the fixed fixture 12 reaches both sides of the fixed frame 102. At this time, the first jaw 2 is located on one side of the fixed frame 102, and the second jaw 3 is located on the other side of the fixed frame 102. The driving motor 131 drives the driving wheel 132 to rotate, so as to drive the rack 151 to penetrate into the fixing part 130, thereby driving the second jaw 3 to move towards the direction close to the first jaw 2. Finally, the first jaw 2 and the second jaw 3 clamp the fixed frame 102. Next, the double-shaft motor 11 drives the connecting rod 13 to swing upward, so that the fixed frame 102 is away from the surface of the conveyor belt 10. Then, the rotary motor 4 drives the fixing bracket to rotate 180°. Then, the double-shaft motor 11 drives the connecting rod 13 to swing downward, and the fixed frame 102 is placed on the conveyor belt 10. The fixed frame 102 is conveyed into the sandblasting machine 101 through the conveyor belt 10 for sandblasting. It should be noted that when the double-shaft motor 11 performs the action of lifting or lowering the fixed frame 102, the rotary motor 4 also drives the fixing jig to rotate at the same angle, so that the fixing jig always maintains a horizontal posture.

[0028] Further, the rack 151 and the guide rod 152 are both provided with sliders 154, and the inner top and inner bottom of the fixing part 130 are both provided with chutes 155. The two chutes 155 are respectively in sliding fit with one slider 154. Specifically, the driving motor 131 drives the driving wheel 132 to rotate, and the rack 151 is driven to move back and forth by the driving wheel 132, so that the sliding part 15 moves back and forth, and the guide rod 152 also moves back and forth. During this process, by setting the slider 154 to slide in the chute 155, the sliding of the sliding part 15 can be made more linear.

[0029] Further, clamping grooves 5 are provided on the inner sides of the first clamping jaw 2 and the second clamping jaw 3, and each of the clamping grooves 5 is used to fix the support column 103. The clamping groove 5 is provided with a flared opening 51, an activity groove 52 is provided in the clamping groove 5, a spring 53 is provided in the activity groove 52, and the spring 53 is sleeved on the flared opening 51. The flared opening 51 is provided with a mounting ring 54 fixedly installed with the spring 53. Specifically, when the first clamping jaw 2 and the second clamping jaw 3 clamp the fixing frame 102, the support column 103 is caught in the flared opening 51, and the spring 53 is compressed during the process of the second clamping jaw 3 continuously moving towards the first clamping jaw 2, causing the flared opening 51 to sink into the activity groove 52, thereby realizing an elastic fixing effect of the first clamping jaw 2 and the second clamping jaw 3 on the support column 103 and improving the grasping stability.

[0030] Working principle: During use, the product is placed in the fixing frame 102 and conveyed into the sandblasting machine 101 through the conveyor belt 10 for sandblasting one side of the product. After completion, the fixing frame 102 is conveyed out by the conveyor belt 10 and captured by the flipping mechanism 1; during this process, the double-shaft motor 11 drives the connecting rod 13 to swing horizontally, and the fixing fixture 12 moves towards the direction close to the fixing frame 102. In order to keep the posture of the fixing fixture 12 horizontal, the rotating shaft is driven to rotate by the driving part, and its rotation angle is the same as that of the connecting rod 13. Finally, the fixing fixture 12 reaches both sides of the fixing frame 102. At this time, the first clamping jaw 2 is located on one side of the fixing frame 102, and the second clamping jaw 3 is located on the other side of the fixing frame 102. The driving motor 131 drives the driving wheel 132 to rotate, thereby driving the rack 151 to penetrate into the fixing part 130, and then driving the second clamping jaw 3 to move towards the direction close to the first clamping jaw 2. Finally, the first clamping jaw 2 and the second clamping jaw 3 clamp the fixing frame 102. Next, the double-shaft motor 11 drives the connecting rod 13 to swing upward, so that the fixing frame 102 is far away from the surface of the conveyor belt 10. Then, the fixing frame is driven to rotate 180° by the driving part. Then, the double-shaft motor 11 drives the connecting rod 13 to swing downward, and the fixing frame 102 is placed on the conveyor belt 10. The fixing frame 102 is conveyed into the sandblasting machine 101 through the conveyor belt 10 for sandblasting, realizing the effect of automatic flipping.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
