Description

Technical Field

[0001] The invention relates to a side tightening device for end surface processing of a support type part and a use method thereof, belonging to the technical field of clamps. Background Art

[0002] In the prior art, the end face (positioning reference surface) of the support parts (such as the mounting support) is usually processed by using a pressing surface and a pressure plate. This method is easy to leave cutting marks on the processing surface (positioning reference surface) during the processing. These marks not only affect the appearance quality of the parts, but also damage the processing accuracy of the positioning reference surface. The positioning reference surface is the reference point for subsequent processing and assembly, and its accuracy is directly related to the accuracy of the remaining positions of the parts processed based on this reference. Therefore, the existence of cutting marks may cause the processing quality of the entire part to fail to meet the standards, thereby affecting the performance of the entire mechanical system.

[0003] In addition, if the machining surface (positioning reference surface) is subjected to improper pressure or force during machining, it may cause a slight change in the position of the part in the fixture. This change is unacceptable in precision machining, thus increasing the risk of secondary positioning of the part. Secondly, since the pressure plate usually needs to be clamped and adjusted multiple times, it not only increases the labor intensity of the workers, but also seriously wastes working hours and reduces production efficiency. Summary of the invention

[0004] In order to solve the problems existing in the background technology, the present invention provides a side tightening device for end surface processing of support parts and a use method thereof.

[0007] The positioning block comprises a right positioning block and a left positioning block; the right positioning block and the left positioning block are arranged in parallel, the left positioning block is an inverted trapezoidal structure, and the height of the left positioning block is higher than that of the right positioning block.

[0009] S1: Visually adjust until the upper surfaces of all vertical supports are on the same horizontal line;

[0010] S2: Place the end surface of the part upward and fit it to the front surface of the fixture;

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The present invention simplifies the adjustment and positioning process of the part processing surface by setting a plurality of vertical supports and springs, facilitates the alignment of the part marking, ensures the accurate relative positioning of the processing position and the casting structure, thereby improving the processing accuracy of the positioning reference surface, and solves the problem of no top pressing of the part positioning in the traditional pressing surface inverted pressure plate method, avoids the generation of cutting marks on the processing surface, and ensures the appearance quality of the part and the accuracy requirements of the positioning reference surface.
