DETAILED DESCRIPTION

[0019] The present application is further described in detail below in conjunction with the accompanying drawings.

[0020] In order to more clearly understand the technical solution presented in the embodiments of the present application, the existing manual polishing of small parts is first introduced.

[0021] In the existing mechanical processing process, including the products processed by precision CNC machine tools, errors still occur, which requires manual processing of some parts with inaccurate dimensions. In the existing processing equipment, manual grinders are mostly used for grinding, and then the surface of the workpiece is polished. For the convenience of operation, these processing processes are often performed manually by hand, which leads to easy shaking during grinding and polishing, and then easily leads to quality problems, affecting the grinding accuracy. In order to solve these problems, the technical solution of this application is proposed.

A through hole is provided in the middle of the connecting plate 1, and the connecting plate 1 is circular in appearance. The supporting legs 2 are fixedly connected to the lower surface of the connecting plate 1 in a rectangular array. The two ends of the connecting rod 3 are respectively fixedly connected to the surfaces of the adjacent supporting legs 2 near the lower ends. The supporting bar 4 is fixedly connected to the connecting rod 3. The lower end of the electric push-pull rod 5 is fixedly connected to the upper surface of the middle position of the supporting bar 4. The lower end of the connecting rod 6 is connected to the upper end of the electric push-pull rod 5. The upper end of the connecting rod 6 passes through the through hole in the middle of the connecting plate 1, and the connecting block 7 is cooperatively connected to the upper end of the connecting rod 6. One end of the pressing plate 8 is fixedly connected to the lower surface of the end of the connecting block 7, and the upper surface of the other end of the pressing plate 8 is fixedly connected with a connecting seat 9. A ring-shaped array of limiting sliding holes 10 is opened on the surface of the connecting plate 1 near the edge position. The lower end of the limiting sliding rod 11 is slidably connected to the limiting sliding hole 10, one end of the pressing rod 12 is slidably connected to the connecting seat 9, and the upper end of the limiting sliding rod 11 is movably connected to one end of the pressing rod 12 away from the connecting seat 9.

[0023] Specifically, the provided connecting plate 1 is used to provide a plane for connection and placement, and is then firmly supported to a certain height by the supporting legs 2 at the lower end, which is convenient for manual standing operation or sitting operation. The specific height can be adjusted according to the actual scene. The provided connecting rod 3 can connect the supporting legs 2 to improve its stability and provide a connection position. The provided support bar 4 can connect the electric push-pull rod 5, so that it drives the upper connecting rod 6 to rise or fall. The electric push-pull rod 5 uses a model with a certain force adjustment control. When a certain torque is reached, it automatically stops and locks in the current position. The provided connecting block 7 is connected to the upper end of the connecting rod 6 and can move with the rise or fall of the connecting rod 6, thereby driving the end pressure plate 8 to rise and move. When in use, the workpiece is placed on the surface of the connecting plate 1, and then when the connecting rod 6 moves down, the pressure plate 8 can move downward, thereby achieving The connection of the workpiece only requires a handheld grinder to grind and polish the flat or curved surface, and then measure the size after grinding to see if it is appropriate.
