Description

Technical Field

[0001] The utility model relates to the technical field of polishing equipment, in particular to a batch polishing equipment for metal parts. Background Art

[0002] The sandblasting machine belongs to the category of air conveying machinery. It uses compressed air in a pipeline to transport powdery particles (with a diameter of 1 - 4 mm) from one place to another. During the process of converting kinetic energy into potential energy, the high-speed moving sand grains scour the surface of the object to improve the surface quality of the object. At present, the sandblasting machine is commonly used for the polishing work of the outer wall of workpieces. When the existing sandblasting machine is used for polishing cylindrical workpieces, the cylindrical workpiece is usually sleeved on the outer wall of the fixed column on the surface of the operating table, and then sandblasting starts. However, the position of the existing sandblasting machine nozzle is fixed during operation, and the distances from the workpiece surface are different, which easily leads to different polishing degrees at different parts of the cylindrical workpiece. In addition, the cylindrical workpiece is not fixed on the outer wall of the fixed column and will shake freely during sandblasting, further resulting in uneven polishing. Based on the above problems, a batch polishing equipment for metal parts is proposed. Content of the Utility Model

A hydraulic cylinder 2 is installed at the top of the housing 1, and the output end of the hydraulic cylinder 2 extends into the inner cavity of the housing 1. The output end of the hydraulic cylinder 2 is installed with a sandblasting machine nozzle 3. Opening the sandblasting machine nozzle 3 can drive the sandblasting machine nozzle 3 to move up and down, so that the end of the sandblasting machine nozzle 3 corresponds to the workpiece. The sandblasting machine nozzle 3 is an existing device, and any general model used for the sandblasting machine can be selected. An installation seat 4 is installed in the inner cavity of the housing 1, and a workbench 5 is installed at the top of the installation seat 4. The installation seat 4 and the workbench 5 are inclined, and the workbench 5 corresponds to the position of the sandblasting machine nozzle 3. The workpiece to be polished is placed on the top of the workbench 5. With the inclined setting, it is convenient for the sand and gravel accumulated on the top of the workbench 5 to slide down and discharge. In addition, a sand outlet 15 is installed at the bottom of the housing 1, and the sand outlet 15 is communicated with the inner cavity of the housing 1. The sliding sand and gravel can automatically concentrate on the sand outlet 15 under the action of gravity and be discharged. A motor 6 is installed on the outer wall of the housing 1, and the output end of the motor 6 extends into the inner cavity of the workbench 5. A first gear 7 is rotatably installed in the inner cavity of the workbench 5, and the first gear 7 is connected to the output end of the motor 6. Opening the motor 6 can drive the first gear 7 to rotate. A plurality of second gears 8 are installed equidistantly along the circumference in the inner cavity of the workbench 5, and the second gears 8 are meshed with the first gear 7. A plurality of internal teeth are installed on the inner wall of the workbench 5, and the plurality of second gears 8 are meshed with the internal teeth. With the cooperation of the workbench 5 and the first gear 7, when the first gear 7 rotates, each second gear 8 can rotate and revolve at the same time.
