Description

Worm milling cutter disc

Technical Field

The utility model relates to a machine adds technical field, concretely relates to worm facing cutter.

Background

A milling cutter disc is generally used as a cutting tool of a milling machine and a processing machine, and in the existing milling cutter disc, when in use, a cutter is arranged on the same plane of the disc, the whole tooth form of the cutter is contacted with a workpiece, the cutting resistance is large, the temperature rise is fast, the processed surface is rough, and the service life of the cutter is short.

Accordingly, to address the above problems, a milling cutter head that overcomes the deficiencies of the prior art is desired.

SUMMERY OF THE UTILITY MODEL

To the not enough of above-mentioned prior art, the utility model aims to solve the technical problem that: how to provide a worm milling cutter dish that can carry out machining better, the design of the installation face reduces the contact surface of cutter and work piece in the processing about the cutter dish, has reduced the vibrations in the course of working, and reduces the cutting heat, has improved cutter life, has improved surface finish quality, and the cutter can exchange about moreover, has reduced cutter use cost on the synthesis.

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

a worm milling cutter disc comprises a cutter disc, wherein a hub is coaxially arranged in the center of the cutter disc in a penetrating mode, a spindle hole is formed in the center of the hub, and a key groove is formed in the circumferential direction of the inner wall of the hub; the edge of the leading flank of blade disc and the trailing flank is along radial indent formation blade holder mounting groove, the blade holder mounting groove dislocation set that leading flank and trailing flank set up, install the blade holder in the mounting groove, install the blade on the blade holder, the tool bit of blade is located the outside of blade disc place circle.

Thus, when milling is carried out, the device can be used for better machining.

Further, the blade holder is the triangle-shaped setting, the equal fixed mounting in three side of blade holder has the blade, the blade holder with the blade disc passes through screw fixed connection. The blades of the cutter holder can be interchanged, so that the service life of the cutter holder is greatly prolonged, and the use cost of a cutter is reduced; through the mode connection of screw, can be faster to the blade holder is changed, has also ensured the stability when milling simultaneously.

Further, the mounting groove that leading flank and trailing flank set up is 4. The number of mounting grooves determines the number of seats to be mounted and, to a certain extent, the milling speed.

Further, the blade holder mounting grooves arranged on the front side surface and the rear side surface are arranged in an arc shape. The arc-shaped arrangement is utilized, so that chips can be better removed; the tool apron mounting groove and the tool pan have certain stability, and smooth milling is guaranteed.

Furthermore, a notch is arranged on the cutter head. Through the notch, on one hand, the weight of the cutter head can be reduced, and the cost is reduced; on the other hand, can hold the sweeps, reduce the influence to the milling process, avoid the sweeps to influence and wait to process work piece surface quality.

In conclusion, the device can better perform mechanical processing, the design of the left and right mounting surfaces of the cutter head reduces the contact surface between the cutter and a workpiece in the processing process, the vibration in the processing process is reduced, the cutting heat is reduced, the service life of the cutter is prolonged, the surface processing quality is improved, the left cutter and the right cutter can be interchanged, and the use cost of the cutter is comprehensively reduced.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

In specific implementation, as shown in fig. 1-4, the worm milling cutter comprises a cutter disc 1, wherein a hub 2 is coaxially arranged in the center of the cutter disc 1 in a penetrating manner, a spindle hole 3 is arranged in the center of the hub 2, and a key groove 4 is circumferentially arranged on the inner wall of the hub 2; the edge of the leading flank of blade disc 1 and the trailing flank forms blade holder mounting groove 5 along radial indent, the 5 dislocation sets of blade holder mounting groove 5 that leading flank and trailing flank set up, install blade holder 6 in the blade holder mounting groove 5, install blade 7 on the blade holder, the tool bit of blade 7 is located the round outside in blade disc 1 place.

In this embodiment, the tool apron 6 is arranged in a triangular shape, the blades 7 are fixedly mounted on three sides of the tool apron, and the tool apron 6 is fixedly connected with the tool pan 1 through screws. The blades of the cutter holder 6 can be interchanged, so that the service life of the cutter holder is greatly prolonged, and the use cost of a cutter is reduced; through the mode connection of screw 8, can be faster to the blade holder 6 is changed, has also ensured the stability when milling simultaneously.

In this embodiment, the number of the tool apron mounting grooves 5 provided on the front side surface and the rear side surface is 4. The number of insert seat mounting grooves 5 determines the number of insert seats 6 to be mounted and, to a certain extent, the speed of milling.

In this embodiment, the tool apron mounting grooves 5 formed on the front side surface and the rear side surface are arc-shaped. The arc-shaped arrangement is utilized, so that chips can be better removed; the tool apron mounting groove 5 and the cutter head 1 have certain stability, and smooth milling is guaranteed.

In this embodiment, the cutter head 1 is provided with a notch 9. Through the notch 9, on one hand, the weight of the cutter head can be reduced, and the cost is reduced; on the other hand, can hold the sweeps, reduce the influence to the milling process, avoid the sweeps to influence and wait to process work piece surface quality.

The working principle and the flow of the mechanism are as follows:

when the worm milling cutter disc is used for machining, firstly, the milling cutter is fixedly installed on the milling cutter disc through screws, and then the milling cutter disc is fixedly installed on a machine tool to be used.
