Description

Technical Field

[0001] The utility model relates to the field of aerospace vehicles, in particular to a round tube polishing device for aerospace vehicles. Background Art

[0002] At present, a Chinese utility model with announcement number CN213532130U discloses an aerospace circular tube polishing device, including a cleaning component, a moving component, an auxiliary component and a positioning component, and it also has a dust collecting component, a main component, a polishing component and an adjustment component; the dust collecting component includes a dust collecting box, a first curved plate, a filter, a suction fan and a first through hole, the inner bottom wall of the dust collecting box is welded with a first curved plate, and the front surface and the rear surface of the first curved plate are both in contact with the inner wall of the dust collecting box; the outer wall of the circular tube is polished by supporting the polishing plate with the second curved plate, and the bristles remove the dust attached to the circular tube, and the slider slides on the inner wall of the slide groove to drive the second curved plate and the polishing plate to move, and the rod body slides on the inner wall of the cylinder, so that the device can ensure that the contact area between the polishing plate and the circular tube is maximized and the force is uniform when polishing circular tubes of different models, thereby improving work efficiency and polishing quality.

[0003] The existing polishing device is not convenient for replacing the polishing wheel. The polishing wheel needs to be replaced after being used for a long time. Generally, the grinding wheel is fixed to the output end of the motor by bolts. When replacing, tools are needed to disassemble and assemble it. The disassembly and assembly process is relatively cumbersome, which increases the workload and reduces the efficiency of replacement. The filter net cannot be cleaned. In order to collect debris, the general polishing device is equipped with a debris collection mechanism. The debris collection mechanism filters and collects the debris through a vacuum fan and a filter net. When collecting the debris, the vacuum fan sucks the debris into the collection box, and the debris will be adsorbed on the surface of the filter net. After long-term use, the debris on the surface of the filter net becomes more and more, causing the filter net to be blocked, affecting the filtration efficiency, and thus affecting the debris collection effect. In order to solve the above-mentioned problems, we propose a polishing device for aerospace circular tubes. Utility Model Content
