[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The following is combined with Figure 1-5 This application is described in further detail.

[0028] Reference Figure 1A sandblasting workpiece positioning device includes a sandblasting machine body 4, a nozzle 3 and a positioning mechanism 5. A machine door 2 is rotatably arranged on the machine body 4, and the machine door 2 covers the machine body 4. A lifting device 1 is arranged on the machine body 4, and the nozzle 3 is connected to the lifting device 1. A sandblasting chamber is arranged in the machine body 4, and the positioning mechanism 5 is arranged in the sandblasting chamber. The nozzle 3 is above the positioning mechanism 5. A display screen 15 is arranged on the machine body 4, and the display screen 15 is electrically connected to the lifting device 1 and the positioning mechanism 5 respectively.

[0029] Place the workpiece on the positioning mechanism 5, close the machine door 2, turn on the lifting device 1 and the positioning mechanism 5 on the display screen 15, the positioning mechanism 5 rotates, and the nozzle 3 sandblasts the workpiece. During the sandblasting process, the lifting device 1 causes the nozzle 3 to continuously move up and down, so that the nozzle 3 sandblasts the workpiece evenly.

[0030] Reference Figure 2 and Figure 3 The positioning mechanism 5 includes a positioning platform 6, a fixing block 9 and a motor 8. The motor 8 is fixedly arranged on the machine body 4, below the sandblasting chamber of the motor 8, and the fixing block 9 is fixedly connected to the rotating shaft of the motor 8. A fixing hole 16 is opened on the side of the sandblasting chamber in the machine body 4 close to the motor 8. The fixing block 9 is located in the fixing hole 16, and the fixing block 9 extends into the sandblasting chamber. A receiving plate 7 is fixedly arranged on the fixing block 9, and a plurality of receiving plates 7 are arranged on the fixing block 9.

[0031] Reference Figure 4 and Figure 5 The positioning platform 6 is a hollow structure. The positioning platform 6 is sleeved on the fixed block 9. The positioning platform 6 abuts against the receiving plate 7. A telescopic rod 10 is fixedly provided on the fixed block 9. A plurality of telescopic rods 10 are provided on the fixed block 9. A tightening plate 13 is fixedly connected to the telescopic rod 10. The tightening plate 13 abuts against the inner wall of the positioning platform 6.

[0032] When the positioning table 6 needs to be replaced due to the different sizes of the sandblasting workpiece, the telescopic rod 10 is started to shrink the telescopic rod 10, and the clamping plate 13 moves with the shrinkage of the telescopic rod 10. When the clamping plate 13 is away from the positioning table 6, the positioning table 6 is pulled upward and the positioning table 6 can be removed. At this time, the positioning table 6 of a suitable size can be replaced, so that the positioning table 6 can be detachably installed in the sandblasting machine, which is convenient for replacing the positioning table 6 to sandblast workpieces of different sizes.

[0033] Reference Figure 3A ball ring 12 is rotatably provided on the fixing block 9, and the ball ring 12 abuts against the fixing hole 16. The ball ring 12 reduces the friction resistance between the fixing block 9 and the fixing hole 16, so that the fixing block 9 rotates more smoothly in the fixing hole 16. A limiting groove 17 is provided on the positioning platform 6, and the limiting groove 17 abuts against the plate 13 located in the limiting groove 17. When the positioning platform 6 is installed on the fixing block 9, the limiting groove 17 and the abutting plate 13 are at the same height, and the limiting groove 17 limits the movement of the positioning platform 6.

[0034] Reference Figure 3 and Figure 5 The positioning platform 6 is fixedly provided with a stabilizing block, which is provided with a stabilizing groove 14, which is sleeved on the fixing block 9. The stabilizing groove 14 plays a role in further improving the stability of the positioning platform 6, so that the positioning platform 6 installed on the fixing block 9 is not easy to move left and right. The end of the positioning platform 6 close to the receiving plate 7 is fixedly provided with a supporting plate 11, which contacts the receiving plate 7. The supporting plate 11 increases the contact area between the positioning platform 6 and the receiving plate 7, reduces the friction between the positioning platform 6 and the receiving plate 7, and prolongs the service life of the receiving plate 7.

[0035] The implementation principle of this embodiment is: when the positioning platform 6 needs to be replaced due to the different sizes of the sandblasting workpieces, the telescopic rod 10 is started to shrink the telescopic rod 10, and the pressing plate 13 moves with the shrinkage of the telescopic rod 10. When the pressing plate 13 is away from the positioning platform 6, the positioning platform 6 is pulled upward and the positioning platform 6 is removed from the fixed block 9. At this time, the positioning platform 6 of the appropriate size can be replaced; after the positioning platform 6 of the appropriate size is replaced, the positioning platform 6 is installed on the fixed block 9 so that the supporting plate 11 contacts the receiving plate 7, the telescopic rod 10 is started, and the pressing plate 13 moves toward the positioning platform 6. As the pressing plate 13 continues to move, the pressing plate 13 presses against the limiting groove 17 of the positioning platform 6. At this time, the positioning platform 6 is stably installed on the fixed block 9, so that the positioning platform 6 can be detachably installed in the sandblasting machine, which is convenient for replacing the positioning platform 6 to sandblast workpieces of different sizes.
