Description

Technical Field

[0001] The invention belongs to the technical field of sandblasting and shot blasting, and particularly relates to a self-rotating multi-station flow micro-sandblasting dust-proof tooling device. Background Art

[0002] In the field of sandblasting, the sand material not only hits the surface of the workpiece with great force, but also the dust enters the interior of the equipment, causing damage to the related components in the equipment. In particular, the moving parts will not be able to operate after entering the sand and gravel. Frequent replacement of components will result in high replacement costs, while increasing the frequency of maintenance and reducing the utilization rate of the equipment. The tooling pallets circulating on the automatic conveyor line are unpowered and cannot rotate, which cannot meet the requirements of the micro-sandblasting process. The interior of the tooling is not fully sealed and dustproof. In order to improve efficiency, the tooling carrying the workpiece needs to flow between different processes on the automatic conveyor line, and during the sandblasting process, the workpiece needs to rotate at a constant speed. Summary of the invention

[0007] Preferably, the multi-station power transmission mechanism consists of a sealed chamber surrounded by a base plate and a second protective cover, a rotating shaft provided on the base plate of the sealed chamber and passing through a third seat bearing, a fourth seat bearing, and a second support along an axis, an oil seal cover passed through the wall of the second protective cover, a dust-proof skeleton oil seal for vertically fixing the rotating shaft oil seal, a workpiece pallet fixed at the end of the rotating shaft passing through the sealed chamber, and a second synchronous wheel mounted on the rotating shaft between the third seat bearing and the fourth seat bearing; the second synchronous wheel and the first synchronous wheel are mounted with a first synchronous belt.

[0008] Preferably: the multi-station power transmission mechanism is composed of a number of rotating shafts connected step by step through synchronous belts and synchronous wheels, and a number of pallets vertically fixed at the ends of the rotating shafts; the first rotating shaft that obtains rotational power transmits the power step by step to the second rotating shaft through the first synchronous wheel and the first synchronous belt, and transmits the power step by step to the third rotating shaft through the second synchronous workpiece wheel and the second synchronous belt, and so on, thereby driving the workpieces on the first workpiece pallet, the second workpiece pallet, and the Xth workpiece pallet to rotate synchronously.
