Description

Technical Field

[0001] The utility model relates to the technical field of cutting tools, in particular to a multi-functional flat chamfering cutter head. Background Art

[0002] When processing workpieces as shown in Figure 1 in a factory, it is necessary to deburr the inner hole of the workpiece step by step and chamfer the circumference, so the workpiece needs to be clamped multiple times on different processing devices, which is time-consuming and laborious, and greatly increases the cumulative error of the workpiece. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a multi-functional flat chamfering cutter head to overcome the above defects in the prior art.

[0004] A multi-functional flat chamfering cutter head includes a tool holder, a grinding column and a cutter head assembly. A connecting shaft is coaxially arranged at the top of the tool holder, the grinding column is coaxially arranged at the bottom of the tool holder, and two cutter head assemblies are symmetrically arranged on the tool holder and on both sides of the grinding column.

[0005] Preferably, the cutter head assembly includes a cutter head body and a cutter bar. The cutter head body is arranged at the lower end of the cutter bar, and the cutter bar is arranged on the tool holder.

[0006] Preferably, the cutter bar is inserted into the mounting hole on the tool holder and abuts against the tool holder through a tightening screw.

[0007] Preferably, the cutter head body is fixed in the cutter groove at the lower end of the cutter bar through a cutter head screw.

[0008] The utility model has the following advantages:

[0009] 1. When the utility model is in use, when the tool holder rotates, the cutter head body on the cutter head assembly chamfers the circumference of the workpiece, and at the same time, the grinding column grinds the inner hole of the workpiece to remove burrs, and the two are carried out synchronously, greatly improving the processing efficiency of the workpiece.

[0010] 2. The cutter bar on the cutter head assembly is detachably installed with the tool holder, and the cutter head body is detachably installed with the cutter bar, which is convenient for disassembling and assembling the above structures. Description of the Drawings

[0017] The specific implementation methods of the utility model are further explained in detail below by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solution of the utility model.

[0018] like Figures 1-5 As shown, the utility model provides a multifunctional flat chamfering cutter head, comprising a cutter holder 1, a grinding column 3 and a cutter head assembly 4, wherein a connecting shaft 2 is coaxially arranged on the top of the cutter holder 1, and the connecting shaft 2 is connected to the main shaft of the processing device, thereby driving the cutter head to rotate, and the grinding column 3 is coaxially arranged at the bottom of the cutter holder 1, and the cutter head assembly 4 is provided with two and symmetrically arranged on the cutter holder 1 and located on both sides of the grinding column 3;

[0019] In addition, the cutter head assembly 4 includes a cutter head body 41 and a cutter bar 42. The cutter head body 41 is fixed in a cutter groove 421 at the lower end of the cutter bar 42 by a cutter head screw 44, so that the cutter head body 41 can be easily disassembled and assembled in the cutter groove 421 of the cutter bar 42.

[0020] In addition, the knife bar 42 is inserted into the mounting hole 11 on the knife holder 1 and abuts against the knife holder 1 through the tightening screw 43. The tightening screw 43 is provided to facilitate the disassembly and assembly of the knife bar 42 on the knife holder 1.

[0021] When the tool holder 1 rotates, the cutter body 41 on the cutter assembly 4 chamfers the circumference of the workpiece, and the grinding column 3 grinds the inner hole of the workpiece to remove burrs. The two are performed synchronously, which greatly improves the processing efficiency of the workpiece.

[0022] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
