Description

Technical Field

[0001] The utility model specifically relates to the technical field of rotary grinding, in particular to a rotary grinding jig. Background Art

[0002] Rotary grinding is a processing method that uses rotary motion to achieve a grinding effect. It is commonly used for surface treatment of materials such as metal, plastic, and wood to remove burrs, smooth the surface, and improve the finish.

[0003] After processing, the shell of a mobile phone or tablet needs to be polished to effectively remove the burrs of the shell and improve the smoothness of the product. However, when polishing the mobile phone shell, the traditional polishing device uses a mechanical clamp to clamp and fix the shell. Although the polishing effect can be achieved, the edges of the clamping position cannot be effectively polished. The shell needs to be disassembled before clamping and polishing. This work efficiency is low and the consistency of the overall smoothness of the shell cannot be effectively guaranteed. There may be deviations, and the overall quality of the product cannot be effectively guaranteed.

[0004] After searching, Chinese patent publication number CN201821198516.1 discloses a mobile phone shell polishing device; it includes an oil pump, an electric motor and a spring, the outer side of the oil pump is connected to an oil storage pipe, and the inner side of the oil storage pipe is connected to an oil cylinder, the electric motor is installed in the middle position of the support frame, and the lower end of the electric motor is connected to a polishing plate, the outer side of the air supply pipe is connected to a dust storage box, and the upper end of the dust storage box is connected to a dust suction pipe, the outer side of the clamping block is connected to an adjusting plate, and the left end of the adjusting plate is connected to a pull rod, a slide rail is installed in the middle position of the pull rod, and a slider is installed inside the slide rail, and the spring is installed on the outer side of the slider;

[0005] The structure in the above patent uses two clamping blocks to clamp and fix the mobile phone shell, and then uses the polishing sheet to effectively polish the mobile phone shell. The distance between the polishing sheet and the clamping block in the above patent cannot be effectively adjusted. As a result, the polishing sheet in the above patent cannot effectively ensure contact with the mobile phone shell when rotating, thus failing to polish the mobile phone. Moreover, the structure in the above patent uses two clamping blocks to clamp the shell. Even if the polishing sheet in the above patent can be adjusted up and down, it is impossible to effectively polish the position of the clamping block, and other equipment is required for auxiliary polishing, which makes the working efficiency of the equipment low.

[0006] In response to the above situation, we provide a rotary grinding jig. In this device, the mobile phone shell to be polished is placed on a matching workbench, and effective magnetic attraction is achieved through the magnetic block in the magnet placement groove. Then, the negative pressure tube and multiple negative pressure adsorption ports are used to achieve negative pressure adsorption and fixation of the mobile phone shell, thereby ensuring the stability of the mobile phone shell during rotary grinding. The fixed plate is driven to rotate effectively by the driving mechanism, so that during the grinding process, the edge of the mobile phone shell is effectively polished. The rotation of the fixed plate is achieved by the rotating table installed at the bottom of the fixed plate. At the same time, the negative pressure tube is connected through the connection between the shell and the rotary joint and the connecting pipe, thereby effectively fixing the negative pressure of the mobile phone shell and ensuring the stability of the mobile phone shell during rotary grinding.
