Description

Anti-drop's combination formula end mill

Technical Field

The utility model relates to a cutter field, concretely relates to anti-drop's combination formula end mill.

Background

Milling cutters are tools commonly used in machine manufacturing, and are rotary tools used for milling operations having one or more cutting teeth that, in operation, intermittently cut off the remainder of a workpiece in sequence. The milling cutter is mainly used for processing planes, steps, grooves, formed surfaces, cut-off workpieces and the like on a milling machine.

At present, the main stream of cutters is mainly an integrated cutter, once a cutting edge is damaged, a cutter handle and other intact parts need to be discarded together, and great waste and pollution are caused. The existing detachable cutter generally adopts the mode that a cylindrical cutter head is inserted into a cutter handle with a cylindrical hole, and the mode can avoid the waste of the cutter head and the cutter handle, but has the hidden danger that the cutter head is not firm to fix and is easy to fall off.

SUMMERY OF THE UTILITY MODEL

The utility model provides an anti-drop's combination formula end mill has solved the easy problem that drops of tool bit that prior art exists, can avoid the tool bit to drop and the waste of handle of a knife when it is used.

In order to solve the technical problem, the utility model provides a following technical scheme:

the utility model provides an anti-drop's combination formula end mill, includes tool bit and handle of a knife, and tool bit one end is the link, and the other end is the edging end, the mounting hole of link embedding handle of a knife is interior to be installed, the link outer wall of tool bit is equipped with the radial plain section of perpendicular to, and the one end lateral part that is equipped with the mounting hole on the handle of a knife is equipped with the fastening screw, the one end of bolt with fastening screw threaded connection to it is fixed with the contact of plain section counterbalance after passing the fastening screw.

The utility model discloses the tool bit adopts the parallel cylinder truncation body in plain section and cylinder axle center, and the plain section aligns with the fastening screw during installation, and the bolt passes the fastening screw, with fastening screw threaded connection, bolt bottom plane with thereby the plain section counterbalance contact is fixed.

Preferably, the number of the flat sections and the number of the fastening screw holes are 3.

Preferably, the flat section is evenly distributed along the circumferential direction of the connecting end at equal intervals, and the fastening screw holes are evenly distributed along the circumferential direction of the tool shank at equal intervals.

Preferably, the peripheral edge of the opening end is four-edged.

Preferably, the end edge of the opening edge end is a double-long tooth.

Compared with the prior art, the utility model, have following advantage:

the tool bit of current cutter generally directly adopts cylindrical link, and this kind of tool bit is difficult to fixed, and is easy not hard up in the handle of a knife, and the tool bit link of this application adopts the parallel cylinder of plano-section and cylinder axle center to cut the body, fixed bolt bottom plane of usefulness with the plano-section looks butt contact is fixed, can prevent that the tool bit from rotating in the handle of a knife in traditional cutter, and the security is high.
