Description

Angle milling cutter

Technical Field

The utility model relates to a milling cutter, especially an angle milling cutter.

Background

A milling cutter is a rotating tool used for milling and having one or more cutter teeth. When in work, each cutter tooth cuts off the allowance of the workpiece in sequence and intermittently. The milling cutter is mainly used for processing planes, steps, grooves, formed surfaces, cut-off workpieces and the like on a milling machine.

Most of the existing angle milling cutters are integrally manufactured, cutter teeth cannot be replaced, however, the cutter teeth are frequently damaged in the using process, and after the cutter teeth are damaged, the whole angle milling cutter cannot be put into use again, so that huge resource waste is caused; simultaneously, angle milling cutter can produce the heat at the during operation, and current angle milling cutter radiating effect is relatively poor, and the cutter body can be harmd to too high temperature, has reduced angle milling cutter's life then.

SUMMERY OF THE UTILITY MODEL

For solving the problem that exists among the background art, the utility model provides an angle milling cutter.

The purpose is achieved, the utility model adopts the following technical proposal: an angle milling cutter comprises a cutter bar, a cutter head, a pressure plate and a plurality of cutter teeth; a plurality of sword teeth can be dismantled with the blade disc and be connected to compress tightly fixedly through the pressure disk, the pressure disk suit is in the outside of cutter arbor to with cutter arbor threaded connection, the lower extreme and the coaxial grafting of blade disc of cutter arbor.

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

1. the cutter teeth of the utility model can be detachably connected with the cutter head, which is convenient for the replacement of the cutter teeth, avoids the scrapping of the whole cutter after the cutter teeth are damaged, and reduces the production cost;

2. the cutter bar of the utility model is provided with a plurality of groups of radiating fan blades, thereby improving the radiating efficiency when in use and prolonging the service life of the whole cutter;

3. the utility model discloses the pressure disk upper surface is equipped with a plurality of heat dissipation lugs, has further improved the radiating efficiency when using, has further improved the life of whole sword.

Detailed Description

The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.

Example 1:

an angle milling cutter comprises a cutter bar 1, a cutter head 2, a pressure plate 4 and a plurality of cutter teeth 3; a plurality of sword teeth 3 can be dismantled with blade disc 2 and be connected to compress tightly fixedly through pressure disk 4, pressure disk 4 closely laminates with the upper end of blade disc 2, pressure disk 4 suit is in the outside of cutter arbor 1 to with 1 threaded connection of cutter arbor, the lower extreme and the coaxial grafting of blade disc 2 of cutter arbor 1.

A plurality of cutter tooth grooves 7 matched with the cutter teeth 3 are uniformly distributed on the outer wall of the cutter head 2 along the circumferential direction, each cutter tooth groove 7 penetrates through the upper end face and the lower end face of the cutter head 2, two side faces of each cutter tooth groove 7 are provided with slots 8 in the same direction as the cutter tooth grooves, and the upper end of each slot 8 penetrates through the upper end face of the cutter head 2; every the both sides face of sword tooth 3 all be equipped with slot 8 assorted inserted block 10, sword tooth 3 can dismantle with blade disc 2 through the mode that inserted block 10 closely inserted corresponding slot 8 and be connected.

Example 2:

this example differs from example 1 in that:

the outer wall of cutter arbor 1 is equipped with multiunit radiating fan 5, multiunit radiating fan 5 sets up along the axial equipartition of cutter arbor 1. The rotation of the plurality of groups of radiating fan blades 5 in the working process can also generate the effect similar to a fan, accelerate the flow velocity of the surrounding air, reduce the temperature of the surrounding environment, further reduce the overall temperature of the cutter,

each group of the heat dissipation fan blades 5 comprises a plurality of heat dissipation fan blades 5, and the plurality of heat dissipation fan blades 5 are uniformly distributed along the circumferential direction of the cutter bar 1.

Example 3:

this example differs from example 2 in that:

the upper surface of the pressure plate 4 is provided with a plurality of heat dissipating fins 6.

The plurality of radiating fins 6 are uniformly distributed along the circumferential direction of the pressure plate 4.

The uniform arrangement of the radiating fins 5 and the radiating lugs 6 can ensure more uniform heat radiation.

When the utility model is used, a plurality of cutter teeth 3 are connected with the cutter head 2 in a way that the insert blocks 10 are tightly inserted into the corresponding slots 8, and then the cutter bar 1 is coaxially inserted into the cutter head 2 and is fastened through keys; then, the pressure plate 4 is sleeved outside the cutter bar 1 and screwed tightly with the cutter bar, so that the pressure plate 4 is tightly attached to the upper end of the cutter head 2, and the position fixation of the cutter teeth 3 is ensured.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
