Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a multi-functional combination cutting tool. Background Technology

[0002] Currently, in the machining field, especially in the processing of nuts for air conditioning shut-off valves, the process requires drilling, then turning the surface and chamfering with an external turning tool, then machining the inner hole with an internal turning tool, then turning the internal thread, and finally turning the relief groove. Six cutting tools are needed to complete the process, which some small multi-tool machine tools cannot handle due to their short travel. More cutting tools mean more time for machine operators to clamp and set the tools, and the process is complex, with long tool change times and low efficiency, resulting in high nut processing costs. Currently, the manufacturing industry faces the challenge of high raw material costs and low processing unit prices. To improve competitiveness, seize market share, and ensure sustainable development, companies must improve processing efficiency and reduce labor costs while maintaining product quality.

[0003] To address these technical problems, a multi-functional combined cutting tool is proposed. Utility Model Content

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a multi-functional combination tool that can reduce the number of tool loading times and time, thereby improving processing efficiency.

[0005] The technical solution adopted by this utility model to solve the problem is: a multi-functional combination tool, including a tool body, an inner hole forming edge integrally formed on the top of the tool body, a transverse groove provided on the top of the tool body, a chip removal groove provided on the side of the transverse groove, a main cutting edge provided in the transverse groove, the height of the main cutting edge being higher than the inner hole forming edge, a grooving edge movably provided in the transverse groove, and a vertical groove also provided on the tool body, with an end face chamfering edge movably provided in the vertical groove.

[0006] As a further improvement to the above technical solution, the main cutting edge includes a first cutting edge, a second cutting edge, and a third cutting edge, which decrease in size from top to bottom. The inner end of the top of the first cutting edge is provided with a first chamfer, and the outer end of the top of the second cutting edge is provided with a second chamfer. The inner edges of the first cutting edge, the second cutting edge, and the third cutting edge are on the same vertical plane.

[0007] As a further improvement to the above technical solution, the inner hole forming blade is divided into a first inner hole forming blade and a second inner hole forming blade by a transverse groove. The size of the first inner hole forming blade is smaller than that of the second inner hole forming blade, and the cross-sections of both the first and second inner hole forming blades are fan-shaped.

[0008] As a further improvement to the above technical solution, the cutting edge of the groove is L-shaped, and the top edge of the cutting edge of the groove extends outward with an extension portion.

[0009] As a further improvement to the above technical solution, the outer side of the blade body is provided with a first screw hole that communicates with the transverse groove, and the screw can pass through the first screw hole and be screwed into the cutting edge of the groove.

[0010] As a further improvement to the above technical solution, a third chamfer is provided on the inner side of the top of the end face chamfering edge.

[0011] As a further improvement to the above technical solution, the outer side of the blade body is provided with a second screw hole that communicates with the vertical groove, and the screw can pass through the second screw hole and be screwed to the end face chamfering edge.

[0012] As a further improvement to the above technical solution, the lower part of the blade body is provided with a mounting part, and the mounting part is provided with a positioning groove.

[0013] The beneficial effects of this utility model are as follows: In use, the main cutting edge can drill a hole in the nut to form an inner hole. The inner hole forming edge can machine the inner hole and end face into place. The grooving edge can machine a relief groove in the inner hole, which facilitates the withdrawal of the tool body. Subsequently, the end face chamfering edge can be used to chamfer the nut. The grooving edge can move vertically and horizontally relative to the transverse groove, thereby adjusting the relative position between the groove and the inner hole. The end face chamfering edge can move vertically relative to the vertical groove. The chamfering angle of the nut can increase or decrease with the vertical movement of the end face chamfering edge. This combination tool can reduce the number of tool replacements and assembly, and the time required, thus ensuring the machining accuracy of the product and improving the product qualification rate. It also saves time and improves the processing efficiency. Attached Figure Description
