Micro polishing devices are usually used in mechanical processing, which can polish the surface of objects. For example, CN21319699U, a micro polishing device for mechanical manufacturing design, is disclosed on the Chinese patent website. It has the advantage of cleaning. Although there are threads inside the fixed frame, the device can use the threads to polish one side of the drill bit, which is easy to use by hand, achieving the beneficial effect of easy polishing of objects, A water outlet is installed on one side of the fixed frame to cool and clean the polished object during the polishing process. However, during the polishing process, it is impossible to determine whether the object is in a horizontal state, resulting in inaccurate polishing. Therefore, a micro polishing device with a universal level is proposed to solve the problem mentioned in the background. Utility Model Content（1） Solved technical issuesIn response to the shortcomings of existing technology, this utility model provides a micro punch with a universal levelThe grinding device has the advantage of convenient viewing of the horizontal state, which solves the problem of not being able to determine whether the object is in a horizontal state during the grinding process, resulting in inaccurate polishing of the object. （2） Technical solutionTo achieve the above objectives, the present utility model provides the following technical solution: a micro polishing device with a universal level, comprising a metal base, wherein the top of the metal base is provided with a groove, and a universal level is installed inside the groove.Preferably, there are three threaded holes on the side of the metal base, each of which is equipped with two locking screws and one axial locking screw. By setting locking screws and axial locking screws, the corresponding locking screws and axial locking screws are tightened and adjusted along the direction of the threaded holes, making it convenient to position the universal level.Preferably, the top of the metal base is provided with a large opening and two small openings. The large opening is equipped with an upper and lower adjustment shaft core, and a clamping tube clamp is installed on the side of the upper and lower adjustment shaft core. A clamping head locking nut is installed between the clamping tube clamp and the upper and lower adjustment shaft core, and horizontal adjustment screws are installed in the two small openings. A clamping tube clamp is set on the side of the upper and lower adjustment shaft core, which can be adjusted according to different objectsSelect the corresponding clamping tube clamp and adjust the screw horizontally to quickly adjust the corresponding positionBy clamping the object accordingly, work efficiency can be improved. By setting a clamp locking nut, the relevant components of the device can be protected, thereby extending the service life of the device components.Compared with existing technology, this utility model provides a miniature polishing device with a universal levelThe device has the following beneficial effects:1. The micro polishing device with a universal level is equipped with a universal level on the top of the metal base. When polishing related components, the horizontal state of the object during polishing can be visually viewed through the function of the universal level. During the polishing process, the universal level can make the polished parts horizontal and uniform in thickness, thereby making the polishing more precise and improving the product's qualification rate.2. This micro polishing device with a universal level is designed with a protruding front of the clamping tube clamp. Different clamping tube clamps can be selected to hold small parts such as watch screws and yellow chips, making it easy to measure the polishing thickness of the parts. By using clamping type adjustment screws, the parts can be quickly clamped, improving processing efficiency.
