[0002] Sandblasting is a process of cleaning and roughening the surface of a substrate by the impact of a high-speed sand stream. Using compressed air as the power, a high-speed jet beam is formed to spray the abrasive (copper ore sand, quartz sand, emery, iron sand, Hainan sand) onto the surface of the workpiece to be processed at a high speed, so that the appearance or shape of the workpiece surface changes. Due to the impact and cutting action of the abrasive on the workpiece surface, the surface of the workpiece obtains a certain cleanliness and different roughness, improving the mechanical properties of the workpiece surface. Therefore, the fatigue resistance of the workpiece is improved, the adhesion between it and the coating is increased, the durability of the coating film is extended, and it is also beneficial to the leveling and decoration of the coating.

At the center of the interior of the support plate 2, there is a through groove 8. On the upper surface of the interior of the through groove 8, there is a front-to-back through limiting groove 9. Between the interior of the limiting groove 9 and the interior of the through groove 8, there is an adjusting component 3. A rotating rod 4 is fixedly penetrated through the interior of the adjusting component 3;

[0028] At the centers of the left and right sides of the interior of the through groove 8, there are left-to-right through through holes 7. The left and right ends of the rotating rod 4 respectively penetrate through the two through holes 7 and are rotationally connected to the through holes 7 through bearings. On one side of the rotating rod 4 close to the center of the interior of the bottom plate 1, there is an installation component 5; During operation, first, the bottom of the bottom plate 1 is made to fit with a flat ground. After the fixture is placed stably, the processing part to be sandblasted is installed through the installation component 5 above the bottom plate 1, and different-sized processing parts can be installed through the installation component 5 for sandblasting. Then, after the installation is stable, sandblasting can be carried out. After sandblasting, the rotating rod 4 can be rotated through the adjusting component 3, and the processing part can be rotated to other surfaces for sandblasting, so that more sandblasting requirements can be met. Therefore, it is convenient to install different-sized processing parts through the installation component 5 and to sandblast different-sized processing parts, making the fixture easy to use and highly practical. At the same time, it is convenient to rotate and adjust the installed processing parts to different surfaces for sandblasting through the adjusting component 3, and the fixture can meet more usage requirements.

[0029] At the center of the interior of the bottom plate 1, there is a vertically through through groove 6, and the interior of the through groove 6 corresponds to the side surface of the installation component 5; During operation, the through groove 6 can prevent the bottom plate 1 from hindering the rotational adjustment of the processing part.

[0030] The installation component 5 includes an inner groove 504 opened at the center inside the rotating rod 4, and one side of the inner groove 504 close to the center inside the bottom plate 1 is communicated with the outside.

A second spring 505 is fixedly connected between the side of the sliding plate 508 away from the center inside the bottom plate 1 and the side of the inner groove 504 away from the center inside the bottom plate 1. A connecting rod 503 is fixedly connected to the center of the side of the sliding plate 508 close to the center inside the bottom plate 1. One end of the connecting rod 503 close to the center inside the bottom plate 1 is fixedly connected to a mounting plate 501. A mounting groove 502 is opened at the center of the side of the mounting plate 501 close to the center inside the bottom plate 1. During operation, by squeezing the mounting plate 501, the mounting plate 501 drives the connecting rod 503 to move. After the connecting rod 503 moves, it drives the sliding plate 508 to slide inside the inner groove 504. Then, after the sliding plate 508 slides, it squeezes the second spring 505 to make the second spring 505 have a rebounding force. And the rebounding force of the spring drives the mounting plate 501 to squeeze and clamp the processing part placed inside the mounting groove 502 for installation. The processing part is clamped and installed by two opposite mounting plates 501. At the same time, the deformation of the second spring 505 enables the two mounting plates 501 to adapt to processing parts of different sizes for installation.
