Description

Technical Field

[0001] This utility model relates to the field of workpiece polishing technology, specifically to a compressor crankshaft polishing machine. Background Technology

[0002] Polishing does not improve the dimensional or geometric accuracy of a workpiece, but aims to achieve a smooth surface or mirror finish, and is sometimes used to eliminate shine. Polishing wheels are typically used as the polishing tool. Polishing wheels are generally made of multiple layers of canvas, felt, or leather, clamped on both sides by metal discs, and their rims are coated with a polishing compound consisting of a uniform mixture of micro-abrasive powder and grease.

[0003] Existing polishing processes mostly rely on manual rotation of polishing equipment, with individuals polishing the workpiece surface using their own skills. Furthermore, the polishing process requires repeated comparisons of the polishing degree on different surfaces to ensure consistent overall polishing precision, which is time-consuming, labor-intensive, and relatively inefficient. Therefore, we propose a compressor crankshaft polishing machine. Utility Model Content

[0005] The technical solution adopted by this utility model to solve its technical problem is a compressor crankshaft polishing machine, including a first motor. The bottom end of the first motor is fixedly installed on one side of the top of the base plate. The end of the base plate away from the first motor is fixedly connected to the side wall of the wheel frame. A guide rail seat is sleeved on the surface of the top extension section of the wheel frame, and the guide rail seat is assembled to the top extension end of the wheel frame by a first bolt. A first guide rail is assembled on the surface of the guide rail seat. A slide rail bearing seat is slidably connected to the surface of the first guide rail.

The small pulley that rotates synchronously with the large pulley drives the abrasive belt wheel 3 and abrasive belt wheel 1 to rotate through the abrasive belt wheel 2 and the abrasive belt installed on its surface, thereby completing the grinding and polishing operation of the workpiece.

[0008] Specifically, the top of the guide rail seat is threaded with a fixed double-ended stud for fixing the spatial position of the slide rail bearing seat.

[0009] By adopting the above technical solution, the connection between the guide rail seat and the slide rail bearing seat is secured by fixing double-ended studs.
