Technical Field

The utility model relates to a milling cutter technical field specifically is an efficient twolip milling cutter.

Background

A milling cutter, which is a rotary cutter for milling having one or more cutter teeth through which margins of a workpiece are intermittently cut in sequence, is mainly used for machining planes, steps, grooves, formed surfaces, cutting off workpieces, and the like on a milling machine, and among them, a double-edged helical milling cutter is also a common milling cutter.

The existing double-edge milling cutter is low in milling efficiency and easy to damage a cutter edge when milling different workpieces, and in addition, the existing milling cutter needs to be replaced by the whole milling cutter as long as a single-edge milling cutter or a straight-edge milling cutter is replaced, so that the use cost is high.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an efficient twolip milling cutter to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an efficient twolip milling cutter, includes handle of a knife, connecting block and tool bit fixed connection, the top of tool bit is provided with the toper sword, the outer lane of tool bit is provided with helical cutting edge, be provided with a plurality of groups of oblique sword between helical cutting edge's the spiral ring.

Preferably, the spiral blade on the cutter head adopts double blades.

Preferably, the inclined direction of the inclined knife edge is consistent with the rotation direction of the spiral knife edge.

Preferably, a thread groove is formed in the top of the knife handle, a threaded rod is arranged at the bottom of the connecting block, and the connecting block is connected with the knife handle through the threaded rod in an inner cavity of the thread groove in a spiral mode.

Compared with the prior art, the beneficial effects of the utility model are that:

1. this efficient twolip milling cutter when carrying out the work piece and milling, the output shaft erection joint of motor on handle of a knife and the lathe, motor drive twolip sword is high-speed rotatory, and the broadsword rotates with same speed simultaneously, can improve the efficiency of the work of milling on the one hand, and on the other hand broadsword forms the support to the spiral sword, plays the effect of strengthening, adds man-hour in the face of the harder work piece of texture, and the helical cutting edge can mill better and not fragile.

2. This efficient twolip milling cutter mills when milling man-hour, because the work piece is different, the milling cutter head that uses probably also can be different, and through setting up detachable milling cutter, when changing milling cutter, only need with tool bit intercommunication connecting block tear open change can, and the handle of a knife need not to be changed, when milling cutter production like this, only need the assembly that a set of handle of a knife just can the various tool bits of adaptation, can be with the material cost and the use cost of reduction in production.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example (b): referring to fig. 1-3, the present invention provides a technical solution: the utility model provides an efficient twolip milling cutter, includes handle of a knife 1, connecting block 2 and tool bit 3, connecting

block

2 and 3 fixed connection of tool bit, and the top of tool bit 3 is provided with toper sword 4, and the outer lane of tool bit 3 is provided with helical cutting edge 5, is provided with a plurality of groups of oblique sword 6 between helical ring of helical cutting edge 5, the twolip of the 5 adoption of helical cutting edge on the tool bit 3.

Furthermore, the inclination direction of the edge of the inclined knife 6 is consistent with the rotation direction of the spiral cutting edge 5, when a workpiece is milled, the knife handle 1 is connected with an output shaft of a motor on a machine tool in an installing mode, the motor drives the double-edged knife to rotate at a high speed, meanwhile, the inclined knife 6 rotates at the same speed, on one hand, the milling efficiency can be improved, on the other hand, the inclined knife 6 supports the spiral cutting edge 5 to play a reinforcing role, and when the workpiece with hard texture is machined, the spiral cutting edge 5 can be better milled and is not easy to damage.

Please refer to fig. 2, a thread groove 7 is formed at the top of the tool holder 1, a threaded rod 8 is arranged at the bottom of the connecting block 2, the connecting block 2 is connected with the tool holder 1 in the inner cavity of the thread groove 7 through the threaded rod 8 in a spiral manner, when milling, since workpieces are different, used milling tool bits may be different, and a detachable milling cutter is arranged, when the milling cutter is replaced, only the tool bit 3 needs to be detached from the connecting block 2 to be replaced, and the tool holder 1 does not need to be replaced, so when the milling cutter is produced, only one group of tool holders are needed to be matched with the assembly of various tool bits 3, and the material cost and the use cost of production can be reduced.

The working principle is as follows: when carrying out the work piece and milling, the output shaft erection joint of motor on handle of a knife 1 and the lathe, motor drive twolip sword is high-speed rotatory, simultaneously the oblique sword 6 rotates with same speed, can improve the efficiency of milling work on the one hand, on the other hand the oblique sword 6 forms the support to helical blade 5, play the effect of strengthening, when adding man-hour facing the work piece that the texture is harder, helical blade 5 can mill better and not fragile, when milling different work pieces with man-hour, can also tear down 3 intercommunication connecting blocks of tool bit 2 and change, only need the assembly that just can the various tool bits of adaptation 3 of a set of handle of a knife like this.

In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
