TECHNICAL FIELD
[0001] The utility model relates to a polishing equipment, especially a joint type polishing head. BACKGROUND
[0002] In the current polishing machine field, the polishing head has a series of significant problems when working. On the one hand, it is difficult to accurately move to the required polishing position, which greatly affects the accuracy and efficiency of the polishing work. When fine polishing of a specific area of an article is required, the positioning deviation of the polishing head will cause it to fail to accurately act on the target position, either leaving a gap with the area to be polished, resulting in incomplete polishing and leaving a rough surface, or excessively approaching or even exceeding the target area, causing uneven polishing force distribution and affecting the overall polishing effect. This inaccuracy problem is particularly evident in mass production, which can lead to uneven polishing quality of the same batch of products, increasing the cost of subsequent quality inspection and rework.
[0003] On the other hand, the existing polishing machine can only realize single translation in the vertical or horizontal direction. This single-dimensional movement greatly limits its application range. Taking common cylindrical articles as an example, if the positions of the articles are relatively flat, such as standard cylindrical shaft parts, this type of polishing machine can smoothly complete the polishing work by moving in a single direction along the axial or radial direction. However, when it comes to complex articles such as stacked cylinders with different diameters, such as stepped shafts and multi-segment special-shaped cylinders, this type of polishing machine is difficult to handle. After stacking cylinders with different diameters, the surface forms a complex undulating surface with different curvatures, and the connection between adjacent cylinders forms a clear step or transition fillet. The existing polishing head cannot move flexibly in multiple dimensions and accurately position, making it difficult to ensure uniform and effective polishing of each cylinder surface.
[0004] Specifically, for the smaller diameter cylinder part in the stacked structure, due to its small radial size and possible location on the inside or recess of the overall structure, the polishing head is limited to single-direction movement and often cannot reach this area and maintain a stable polishing posture, resulting in insufficient polishing force and substandard surface finish. For the edges of larger diameter cylinders and the parts where other cylinders meet, due to the height difference or angle change, the polishing head either misses the connection area due to fixed movement trajectory, forming a polishing dead angle, or causes local over-polishing due to improper contact angle with the surface, even damaging the corner structure of the workpiece. This not only reduces the polishing quality of the product, but also can lead to the production of a large number of defective products, increasing production costs and severely restricting the development and upgrading of related industries in the field of complex special-shaped part processing.
