Description

Technical Field

[0001] The utility model belongs to the technical field of workpiece grinding and polishing, and in particular relates to a polishing mechanism which is convenient for adjusting a processing angle. Background Art

[0002] After the workpiece is processed, it is usually necessary to grind and polish the surface and remove burrs to improve the surface structure of the workpiece and enhance its performance. At present, mechanical polishing is commonly used in the polishing process. Mechanical polishing is generally only suitable for flat workpiece surfaces. When polishing a part of a workpiece with a special structure, such as a special-shaped workpiece with an uneven edge or surface area, it is not convenient to process it through an assembly line polishing procedure.

[0003] Therefore, at present, when polishing the uneven edges or surface areas of special-shaped workpieces, it is necessary to manually hold the workpiece or polishing equipment for mobile grinding and polishing. The reasonable position relationship between the workpiece and the polished workpiece must be manually maintained throughout the process to ensure the polishing accuracy. Due to the special structure of the workpiece, the processing is time-consuming, labor-intensive, and has low work efficiency. On the other hand, concentrating on operation for a long time not only consumes physical energy but also easily leads to mental fatigue, further increasing the chance of injury to personnel or workpieces, which is not conducive to safe production.

[0005] The utility model is realized by the following technical scheme: it comprises a lower adjustment mechanism and a polishing machine arranged at the lower end of the lower adjustment mechanism, an upper adjustment mechanism is arranged on the top of the lower adjustment mechanism, the lower adjustment mechanism comprises a rotating mechanism, a mounting plate, an arc guide rail, a guide rod, and a lower adjustment driving member, and a mounting plate is movably hingedly arranged on any side edge of the bottom of the rotating mechanism, and the connection combination of the two is a hinge-like structure, a U-shaped groove is arranged at one end of the mounting plate opposite to the hinge part, so that the end of the mounting plate is arranged in a concave shape, and the polishing machine is coaxially arranged at the bottom of the mounting plate, the arc guide rails are symmetrically arranged on the inner side of the U-shaped groove of the mounting plate, the upper end of each arc guide rail is fixedly connected to the bottom of the rotating mechanism, and the lower end extends downward to the lower part of the polishing machine, each of the arc guide rails is provided with a guide groove, and a guide rod is arranged on the inner side of the U-shaped groove corresponding to each guide groove, the lower end of the lower adjustment driving member is movably hingedly arranged at the lower part of the polishing machine, and the upper end passes through the U-shaped groove upward to movably hinge the bottom of the rotating mechanism, and the lower adjustment driving member is located between the two arc guide rails.

[0006] The beneficial effects of the utility model are as follows: the utility model has high operating stability, and adopts a combination of a lower adjustment mechanism and an upper adjustment mechanism to realize the adjustment and compensation adjustment of the polishing inclination angle. The two can operate independently, and can also be combined and linked to operate, and can also perform circular rotation adjustment, which greatly improves the adjustment demand of the polishing inclination angle, and the operation is more flexible. It overcomes the special structural limitations of the workpiece and can effectively meet the polishing processing requirements for the surface of special-shaped parts; there is no need for manual polishing throughout the process, which reduces labor intensity, greatly reduces the chance of injury to personnel or workpieces, is conducive to safe production, and improves production efficiency.
