The pneumatic polishing machine 4 includes a polishing machine housing 61, a runner assembly 62 arranged inside the polishing machine housing 61, and an air inlet switch assembly 63 connected to the polishing machine housing 61. The polishing machine housing 61 includes a housing sheath 65, a main housing 66, and a dust cover 67 arranged in sequence from top to bottom. A runner hole 69 for installing a polishing wheel is provided at the bottom of the runner assembly 62. The main housing 66 includes a housing upper clamping part 70, a housing main cover part 71, and a housing lower clamping part 72 that are clamped to the housing sheath 65. The dust cover 67 includes a dust cover arc body 74 and a dust cover edge 75 that are clamped to the housing lower clamping part 72. A retaining edge limit notch 77 is provided on the dust cover edge 75. Before the pneumatic polishing machine is assembled and shipped from the factory, we need to perform a rotation test on the runner assembly 62 of the pneumatic polishing machine 4. On the one hand, it is necessary to detect whether the rotation action of the runner assembly 62 is normal, and on the other hand, it is necessary to detect whether there is any jamming or interference problem between the runner assembly 62 and the polishing machine housing 61 during rotation to ensure the qualification rate of the product. The traditional method uses manual holding for testing, which has the problems of poor detection accuracy and low detection efficiency, and improvements and optimizations are made in response to this.

The clamping buffer block is provided with a buffer block limiting groove for buffering and clamping the arc-shaped body of the dust cover, and a buffer block guiding protrusion capable of horizontally moving in the clamping block guiding groove is arranged above the clamping buffer block. One end of the buffer spring abuts against the side of the clamping buffer block and the other end abuts against the inner side of the end sealing plate. The buffer docking block is provided with a docking block positioning notch corresponding to the base positioning protrusion.
