Description

Technical Field

[0001] The utility model relates to the technical field of material processing of engraving and milling machines, in particular to a material fixing fixture for high-speed engraving and milling. Background Art

[0002] Engraving and milling machines are a type of CNC machine tools. Engraving and milling machines are generally considered to be CNC milling machines that use small tools, high-power and high-speed spindle motors. The advantage of engraving machines is engraving, and if the hardness of the processed material is relatively high, it will be incapable of doing so. The emergence of engraving and milling machines can be said to fill the gap between the two. During the use of engraving and milling machines, special fixtures are needed to position and clamp the materials, so that the materials remain relatively stable during the engraving and milling process, thereby improving the processing quality of the workpiece.

[0003] In view of this, Chinese Patent No. CN208698310U proposes a clamp for a milling machine that is convenient for fixing materials. The clamp for the milling machine reduces the shaking of the placement table by squeezing the second telescopic rod, and the roller fixes the surrounding of the milling cutter to increase the stability of the placement table. The shock-absorbing pad reduces the vibration of the machine on the placement table when it is working, avoids affecting the engraving accuracy, and improves the work quality. However, during the use of the above-mentioned material fixing clamp, since the milling machine is mainly used for engraving and milling operations, a large amount of material waste will be generated at the upper end of the clamp during such operations. The structure of the upper end of the machine is complicated, and it will be very troublesome to clean it manually in the later stage, and it may even be necessary to disassemble the clamp to proceed, which wastes time and increases labor costs. Therefore, a clamp structure that automatically cleans and collects waste is needed. Utility Model Content
