Description
Technical Field
[0001] The utility model relates to the technical field of mechanical processing, in particular to a polishing structure suitable for shaft parts. Background Art
[0002] At present, in the modern production and manufacturing process of shaft parts, in order to meet the needs of mass production, improve the efficiency of the grinding process, and meet the needs of high surface quality, a separate polishing process is usually arranged to polish the parts. The equipment used in the existing polishing process is usually a dedicated polishing machine. The polishing machine drives the connecting arm through a hydraulic drive device to make the polishing pad press the sand belt on the part so that the sand belt contacts the outer surface of the part, and then drives the part to rotate through the machine tool, so that the sand belt polishes the part. In this process, the polishing pad plays an extremely important role. The quality, precision and stability of the polishing pad will directly affect the polishing effect. The defects of the polishing pad will directly lead to the scrapping of the part and cause losses.
[0003] At present, the existing polishing pads are usually connected to the output end of the pressing drive device. The polishing grooves on the polishing pads are pressed against the parts by pressing down, and then the parts are rotated for polishing. When fixed in this way, the parts only receive the pressing force in the vertical direction, but are not subject to the corresponding restraining force in the horizontal direction. They are prone to certain movement and displacement in the horizontal direction, and have poor stability, which causes the parts to not fit tightly against the sandpaper and cause slippage, resulting in poor polishing effect. At the same time, the lack of stability will also lead to large vibrations during the polishing process. Long-term use may cause certain damage to the machine tool, and during the polishing process, the vibration may also cause scratches on the parts and damage to the quality. Utility Model Content

By setting the locking rod, when the movable polishing pads press the part shaft, an additional lateral pressure perpendicular to the longitudinal pressure can be provided to the part shaft, so that the part shaft is evenly stressed and the stability of the part shaft during polishing is improved. At the same time, it can also effectively avoid the occurrence of vibration and movement of the part shaft, so that the sandpaper and the part shaft are in full contact to ensure the polishing effect.

Since the movable polishing tiles and the locking rod can slide relative to each other, the return spring is used to ensure that the movable polishing tiles are always abutted against the fixing parts and will not slide freely on the locking rod. In addition, the return spring can also play a certain buffering role to avoid collision between the movable polishing tiles and cause structural damage.
[0013] Furthermore, as a preferred technical solution, the groove surface of the arc-shaped polishing groove is a circular arc surface.
