Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing equipment, in particular to a flat processing device for mechanical processing parts. Background Art

[0002] Machining refers to the process of changing the shape, size or performance of a workpiece through a mechanical device. It can be divided into cutting and pressure processing according to the difference in processing methods. It refers to the entire process of making products from raw materials. For machine production, it includes the transportation and storage of raw materials, production preparation, blank manufacturing, parts processing and heat treatment. When there are burrs and uneven protrusions on the surface of the workpiece, it is even more necessary to perform mechanical processing to grind its surface to make it smooth. While grinding, attention should also be paid to the smoothness of the workpiece surface.

[0003] The existing leveling processing device for machined parts places the machined part on the upper side of the fixed table, and then rotates the handle to make the external threaded rod drive the clamping block to limit and fix the machined part. In this way, the machined part is not easily displaced during the leveling processing. However, the thickness of different machined parts is different. If the thickness of the machined part is less than the height of the clamping block, the grinding wheel may collide with the clamping block during the leveling processing, affecting the normal processing. In addition, the sizes of different machined parts are also different, which makes it inconvenient to fix machined parts of different sizes. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a flattening device for machined parts, which can effectively avoid the collision between the grinding wheel and the clamping block, enable the flattening process to proceed normally, and facilitate the fixation of machined parts of different sizes.

[0011] Compared with the prior art, the utility model has the following beneficial effects: when in use, the height of the T-shaped adjustment plate is first adjusted according to the thickness and size of the machined workpiece, and then the clamping position of the clamping block is adjusted.

During the grinding process, since the upper edge height of the clamp block is lower than the upper surface of the machined part, the grinding wheel will not contact the clamp block when it reciprocates, ensuring smooth grinding work, thereby effectively avoiding the collision between the grinding wheel and the clamp block, allowing the leveling process to proceed normally, and facilitating the fixation of machined parts of different sizes.
