Novel milling cutter

Abstract

The utility model provides a novel milling cutter, and belongs to the technical field of cutters. The problem that a blade on an existing milling cutter cannot be independently replaced is solved. The novel milling cutter comprises a cylindrical cutter head, a plurality of blades are mounted on the cutter head in a spiral line shape, a plurality of cutter grooves for mounting the corresponding blades are formed in the cutter head, the blades are mounted on the corresponding cutter grooves in an indexable manner, the blades are of rectangular structures, and inwards-sunken positioning grooves are formed in the two ends of each blade. A positioning part which protrudes outwards and is used for positioning and connecting the positioning groove of the blade is arranged on the cutter groove of the cutter head, a positioning edge which abuts against the groove wall of the cutter groove is arranged on the positioning part, and an arc surface which is arranged towards the direction of the positioning groove is arranged on the periphery of the end part of the blade. The utility model has the advantages that the blade can be detached and installed independently and is installed stably.

Description

Technical Field

[0001] The utility model belongs to the technical field of tool tools and relates to a milling cutter, in particular to a new type of milling cutter. Background Art

[0002] Currently, the milling cutters on the market are usually integrated with the cutter disc and blade. However, when one of the blades is excessively worn and needs to be replaced, the entire milling cutter needs to be discarded, resulting in a waste of processing resources. Summary of the invention

[0003] The utility model aims to solve the above problems in the prior art and provides a new milling cutter with a detachable and stably installed blade.

[0004] The purpose of the utility model can be achieved through the following technical solutions: A new type of milling cutter, characterized in that it includes a cylindrical cutter disc, a plurality of blades are installed on the cutter disc in a spiral shape, the cutter disc has a plurality of tool grooves for installing corresponding blades, and the blades can be installed in the corresponding tool grooves in a rotatable manner, the blades are of a rectangular structure, and both ends of the blades have inwardly recessed positioning grooves, the tool groove of the cutter disc has a positioning portion that protrudes outward and is provided for the positioning groove of the blade to be positioned and connected, the positioning portion has a positioning edge that abuts against the groove wall of the tool groove, and the periphery of the end of the blade has an arc surface opened in the direction of the positioning groove.

[0005] In the above-mentioned novel milling cutter, the blade is mounted on the cutter disc by screws.

[0006] Compared with the prior art, the novel milling cutter has the advantages that the blade can be detached and installed separately and the blade can be installed stably. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 2 It is a partial enlarged view of the new milling cutter.

[0009] In the figure, 1, cutter disc; 2, blade; 3, cutter groove; 4, positioning groove; 5, positioning part; 6, positioning edge; 7, arc surface. DETAILED DESCRIPTION

[0010] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0011] like Figure 1 , Figure 2As shown, the new milling cutter comprises a cylindrical cutter disc 1, on which a plurality of blades 2 are installed in a spiral shape, the cutter disc 1 has a plurality of tool grooves 3 for installing corresponding blades 2, and the blades 2 can be installed in a rotatable manner on the corresponding tool grooves 3, the blades 2 are rectangular in structure, and both ends of the blades 2 have inwardly recessed positioning grooves 4, the tool grooves 3 of the cutter disc 1 have a positioning portion 5 which protrudes outward and is provided for the positioning grooves 4 of the blade 2 to be positioned and connected, the positioning portion 5 has a positioning edge 6 which abuts against the groove wall of the tool groove 3, the periphery of the end of the blade 2 has an arc surface 7 opened in the direction of the positioning groove 4, the positioning portion 5 and the positioning groove 4 are snap-fitted together to make the installation of the blade 2 more stable, and the positioning edge 6 is limited in four directions to improve the installation stability of the blade 2.

[0012] Preferably, the blade 2 is mounted on the cutter disc 1 by screws.

[0013] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0014] Although the terms such as cutter disc 1, blade 2, cutter groove 3, positioning groove 4, positioning portion 5, positioning edge 6, arc surface 7 are used more frequently in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
