Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of machining, specifically relates to a compound machining tool. BACKGROUND

[0002] The boring and milling machining of the common hole system of product parts generally simultaneously exists the machining of the hole edge chamfer. The traditional machining mode mostly adopts different tools for machining the hole and the chamfer respectively. The different tools for machining the different hole and chamfer of the same hole system cause the increase of tool changing frequency and the increase of tool quantity. When the same hole system is machined by the same tool with multiple blades, one blade is only responsible for the machining of one part or surface, and the tool with multiple blades is used for completing different machining contents, so that the machining stability of the tool is influenced, and the management difficulty is increased. Therefore, for the traditional machining mode, the utilization rate of the tool is relatively low, and the machining efficiency is influenced. SUMMARY

[0003] (I) Technical problem to be solved

[0004] The utility model provides a compound machining tool to solve how to simultaneously complete the machining of the different hole and chamfer of the same hole system, change the tool once, and simultaneously complete the machining of the different hole and hole edge chamfer by one tool, and improve the machining efficiency.

[0005] (II) Technical scheme

[0006] In order to solve the above technical problem, the utility model provides a compound machining tool, which comprises a tool bar and a blade, wherein the front end of the tool bar is processed with multiple steps, and each step corresponds to a blade installed in the corresponding tool groove.

[0007] Further, the types of the blades installed in the corresponding tool grooves of each step are the same.

[0008] Further, the types of the blades installed in the corresponding tool grooves of each step are different.

[0009] Further, the blade is a indexable blade.

[0010] Further, the blade is fixed in the corresponding tool groove of the step through a blade fixing screw.

[0011] (III) Advantages

[0012] This invention proposes a composite machining tool, comprising a tool holder and inserts. The tool holder has multiple steps machined at its front end, with inserts installed in the corresponding grooves of each step. Using the same tool holder, multiple tool rests are set at different positions on the tool holder according to product characteristics. Different or identical inserts are fixed in their theoretically correct positions to collectively complete the machining of holes and chamfered edges. The inserts are installed in directions suitable for hole and chamfer machining. The installation position of the inserts is determined based on the size and position of the hole and chamfer, ensuring that the hole diameter is machined while simultaneously producing a chamfer of the appropriate size. This allows a single insert to perform both boring and chamfering machining. This invention employs a tool design method that conforms to the characteristics of hole machining, rationally arranging the inserts to ensure that the machining process, including hole and chamfer machining, is completed simultaneously using a single tool. This reduces the number of tool changes and tool change time, effectively improving machining efficiency. Attached Figure Description
