Sand blasting is a workpiece surface treatment process, which uses compressed air to spray materials (copper ore sand, quartz sand, corundum, etc.) at high speed to the surface of the workpiece to be treated, so as to form impact and cutting on the surface of the workpiece, so that the workpiece surface obtains a certain cleanliness and different roughness, improves the mechanical properties of the workpiece, and increases the adhesion between the workpiece and the coating.

[0003] In the processing of the tappet, the inner and outer surfaces of the tappet need to be sand blasted to facilitate the adhesion of the subsequent tappet surface coating and improve the mechanical properties of the tappet.

[0049] This embodiment provides a tappet sandblasting device, which, based on the solution described in Embodiment 1, further includes, as follows: Figure 9 The supporting column 217, the fourth rotating mechanism 218, the rotating rod 219, and the pressing rod 220 are shown.

[0050] Preferred, such as Figure 1 , Figure 3 , Figure 9 As shown, both ends of the support platform 22 are vertically provided with support columns 217, and a rotating rod 219 is rotatably connected between the support columns 217. The rotating rod 219 is arranged along the length of the sandblasting table 1. One of the support platforms 22 is provided with a fourth rotating mechanism 218 coaxial with the rotating rod 219. The fourth rotating mechanism 218 can be a rotary drive mechanical device such as a rotary motor or a rotary cylinder. The drive shaft of the fourth rotating mechanism 218 is connected to the rotating rod 219. The rotating rod 219 is vertically connected with a number of pressing rods 220 matching the number of pressing blocks 212. The pressing rods 220 are used to contact the pressing blocks 212 and move them toward the second fixed block 29.

[0051] When the positioning plate 21 needs to be withdrawn from the sandblasting tank 11, the fourth rotating mechanism 218 is started to rotate the rotating rod 219, and then the pressing rod 220 is brought into contact with the pressing block 212 and moves towards the second fixed block 29, and after moving a certain distance, the pressing rod 220 is limited to move away from the second fixed block 29; at this time, the first rotating mechanism 214 is started to slowly move the rotating belt 210 wound on the winding column 215 away from the winding column, and the first spring 26 drives the positioning plate 21 to return to the containing groove 23; such a design can prevent the positioning plate 21 from being stuck during the process of withdrawing from the sandblasting tank 11 due to the contact between the pressing groove on the pressing block 212 and the rotating belt 210 on the first fixed column 28, so that the equipment runs more stably.

[0052] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Obviously, those skilled in the art can make various modifications and changes to the present application without departing from the spirit and scope of the present application.
