Technical Field

[0001] The utility model relates to the technical field of sandblasting machines, in particular to a sandblasting machine used for composite PVD coatings. Background Art

[0002] The sandblasting machine for composite PVD coating is a machine that uses the impact of high-speed sand flow to clean and roughen the surface of the substrate. It uses compressed air as power to form a high-speed jet beam to spray the composite PVD material at high speed onto the surface of the workpiece to be processed, so that the appearance or shape of the outer surface of the workpiece changes.

[0003] When implementing this technical solution, at least the following drawbacks still exist: although existing sandblasting machines can process workpieces, sandblasting gloves are easily damaged and difficult to replace quickly, and are in urgent need of improvement. Therefore, we propose a sandblasting machine for composite PVD coating. Utility Model Content

[0004] The purpose of the utility model is to provide a sandblasting machine for composite PVD coating, which solves the problems raised in the background technology.

[0006] By adopting the above technical solution, it is convenient to make the pressure ring press the edge of the sandblasting gloves, and then rotate the limit ring. The internal thread on the inner side of the limit ring cooperates with the external thread to limit the limit strip on the pressure ring, so that the pressure ring presses and limits the sandblasting gloves. At the same time, the special-shaped clip on the pressure ring and the special-shaped slot on the sandblasting machine body are cooperated to ensure the limiting effect of the pressure ring on the sandblasting gloves.

[0007] Optionally, the size of the special-shaped card piece is adapted to the size of the special-shaped card slot, and the special-shaped card piece is movably connected to the special-shaped card slot.

[0008] By adopting the above technical solution, the limiting effect of the sandblasting gloves can be easily ensured.

[0009] Optionally, the special-shaped card slots are distributed in a ring shape, and the special-shaped card slots correspond to the special-shaped card parts one by one.

[0010] By adopting the above technical solution, the stability of the pressure ring can be ensured.

[0011] Optionally, limiting strips are welded around the four sides of the pressure ring, and the limiting strips are movably connected to the sandblasting machine body.

[0012] By adopting the above technical solution, the limiting bar can be easily moved.

[0013] Optionally, an external thread is provided on the outer side of the limiting strip, and the external thread is spirally connected to the internal thread.

[0014] By adopting the above technical solution, it is convenient to limit the pressure ring.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] The technical solution of the present application is to provide a sandblasting machine body, sandblasting gloves, a pressure ring, a special-shaped groove, an internal thread and an external thread. During maintenance, the limit ring can simultaneously drive the four limit bars to move to the left, so that the pressure ring can press and limit the sandblasting gloves, and the sandblasting gloves can be installed more quickly. At the same time, the special-shaped clips on the pressure ring and the special-shaped grooves on the sandblasting machine body can be used to ensure the limiting effect of the pressure ring on the sandblasting gloves, thereby avoiding the poor sealing of the sandblasting gloves after installation, and further ensuring the sandblasting effect of the sandblasting machine.
