Description

Technical Field

[0001] This utility model relates to the field of parts processing technology, specifically a multi-purpose composite tool body. Background Technology

[0002] In daily life and professional work, single-function cutting tools often cannot meet diverse needs, leading to the development of multi-purpose composite cutting tools. Through ingenious structural design and functional integration, this tool integrates multiple cutting and machining capabilities, effectively improving efficiency and convenience.

[0003] When cutting a part with two annular grooves on its surface, multiple different cutting tools are required to cut the part surface. During cutting, different cutting tools need to be replaced, which takes a long time and reduces the processing efficiency of the part. It cannot be processed in one go. Moreover, the existing cutting tool structure is relatively complex and the design is relatively simple. Its cutting tool width value is low, resulting in low processing efficiency.

[0006] The blade is installed in a groove and includes a blade piece. The blade piece has a through hole and a limit block is provided at one end. The other end of the blade piece is provided with a first cutter head and a second cutter head. The first cutter head includes a beveled surface and a guide surface, and a cutting head is formed between the beveled surface and the beveled surface.

[0007] A screw passes through a through hole and a threaded hole from the outside in, fixing the blade to the blade holder.

[0009] Preferably, both the first limiting surface and the second limiting surface form an angle with the groove, and the angle value of the angle is 80°.

[0010] Preferably, the end of the blade with the groove is provided with a guide groove and a support block. The guide groove includes a guide surface and a discharge surface. The guide surface is inclined and the width of the discharge surface gradually increases from the end near the groove to the other end. The support block is stepped.

[0011] Preferably, the limiting block has an inclined positioning surface on the side away from the blade, and the positioning surface forms an angle with the vertical surface, the angle being 10°.

[0012] Preferably, the cutting head is arranged in a figure-7 shape and is connected to the second blade head. The second blade head includes a first cutting block and a second cutting block.
