Technical Field
[0001] This utility model relates to the field of mechanical processing equipment technology, specifically to a polishing device for processing mechanical parts. Background Technology
[0002] Polishing is frequently required when manufacturing or refurbishing mechanical parts. It's a processing method that reduces surface roughness, resulting in a bright, smooth surface. During polishing, a high-speed rotating polishing head presses against the workpiece, causing the abrasive to roll and micro-cut the surface, removing rough particles and achieving a mirror-like shine. This not only improves the product's appearance but is also essential for ensuring the fit of parts, playing a crucial role. However, polishing small or complex-shaped parts becomes very difficult using this method, necessitating chemical polishing, high-pressure sandblasting, or sandpaper grinding. These methods are complex, labor-intensive, prone to contamination, and prone to uneven polishing. A new type of polishing equipment is needed to address these issues. Utility Model Content

The spring seat includes a seat plate 7, and the bottom surface of the seat plate 7 has several protrusions 701. The protrusions 701 are inserted into the upper end of a spring 8, and the lower end of the spring 8 is inserted into a corresponding spring seat 101 on the bottom surface of the housing 1. Several layers of sand boxes 2 are stacked on the seat plate 7. The bottom expansion plate of the sand box 2 has a recessed groove 201. The top of the seat plate 7 and the opening of the sand box 2 can be embedded into the recessed groove 201 for stacking connection. Several pairs of slots 202 are symmetrically opened on both sides of the opening of the sand box 2. The pairs of slots 202 cooperate with the inserts 301 on both sides of the top of the partition plate 3. The bottom of the partition plate 3 can be inserted into the groove 203 on the bottom surface of the sand box 2, so that the interior of the sand box 2 is quickly divided into several compartments, and polishing sand 4 is placed inside the compartments.
[0018] In this embodiment, the uppermost sandbox 2 is closed by a lid 5. The lid 5 has handles 501 on both sides of its top surface. The lid 5 is connected to the mounting base 9 in the vibration mechanism at the center of its top surface. The mounting base 9 is rotatably connected to the driven shaft 10 on both sides. The driven shaft 10 extends out of the mounting base 9 and is connected to the eccentric block 11. The driven shaft 10 shaft gear meshes with the transmission gear 12 built into the mounting base 9. The transmission gear 12 meshes with the shaft gear of the drive shaft 13. One end of the drive shaft 13 extends out of the mounting base 9 and is connected to the universal joint 14. The other end of the universal joint 14 is connected to the connecting sleeve 15 through a pin structure. The spline inside the connecting sleeve 15 is slidably connected to the external spline of the output shaft of the drive motor 6.
