Problems solved by technology

This structure effectively embeds the cutter head in the dovetail groove of the cutter body, which reduces the probability of the cutter head flying out due to the huge centrifugal force, but this structure requires a longitudinal groove on the cutter head, which greatly reduces the The strength of the cutter head, thus reducing the service life of the cutter head

Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as figure 1 , figure 2 As shown, an embodiment of a milling cutter with an anti-flying structure of the present invention includes a cutter body 1 and a blade 2. The cutter body 1 is provided with a connected knife groove 111 and a briquetting groove 113, and the sipe 111 and the briquetting block The grooves 113 are arranged along the circumferential direction of the cutter body 1 . The blade 2 is installed in the knife groove 111 through the blade fastener (the blade screw 3 in this embodiment). The blade center hole, when installing the blade 2, insert the blade screw 3 into the blade center hole and the blade installation hole 1111 and tighten. The pressing block groove 113 is provided with a pressing block locking installation hole 1131 opened along the axial direction of the cutter body 1, and the elastic pressin...

Abstract

The invention discloses a milling cutter having a fly-off prevention structure. The milling cutter comprises a cutter body and a blade, the blade is provided with a cutter groove, the blade is installed in the cutter groove through a blade fastener, the cutter body is also provided with a briquetted block groove connected with the cutter groove, an elastic briquetted block is fixedly installed in the briquetted block groove, and the elastic briquetted block is in force fit with the blade. The miller cutter has the advantages of simple and compact structure, low cost, guarantee of the strength of the blade, and prolongation of the service life of the blade.

Description

technical field [0001] The invention mainly relates to the field of cutting tools, in particular to a milling cutter with an anti-flying structure. Background technique [0002] During the high-speed cutting process of the milling cutter, due to the huge centrifugal force generated by the high-speed rotation of the milling cutter, the cutting blade is more likely to fly out and cause processing accidents, so it is particularly important to set a reasonable anti-flying mechanism on the milling cutter. [0003] In the field of high-speed cutting, the milling cutter announced by CN1929945 has a cutter head fixed in the dovetail groove on the cutter body by a clamping screw, and there is a longitudinal groove in the through hole area where the clamping screw is installed on the cutter head. It can be straight or circular or bean-shaped. The clamping screw for fixing the cutter head has a conical screw head. When the cutter head is fixed, the longitudinal groove is expanded by t...
