Abstract

The invention discloses a cutter for a numerical control machine tool, and belongs to the technical field of machining equipment. The opposite corners of the cutter are provided with a first installing base of a first blade and a second installing base of a second blade respectively, wherein the first installing base and the second installing base are symmetrical, and a third installing base and a fourth installing base are symmetrically arranged on the two sides of the axis center of the cutter behind the first installing base and the second installing base. Under the installing situation of an existing cutter blade, the third installing base and the fourth installing base of the blades are symmetrically arranged behind the first installing base and the second installing base so that the blades can be replaced to the symmetrical positions behind the blades to be installed and used again after being abraded seriously at the original positions, the machining capability of the blades is utilized to the greatest extent, and the waste degree of the blades and the machining cost of a workpiece are reduced. All edge angle parts of the blades can be utilized by only changing the rotation reverse direction of a main shaft of the machine tool without replacing a cutter shaft, and the utilization ratio of the blades is maximized.

Description

A kind of Digit Control Machine Tool cutterhead

Technical field

The present invention relates to machining apparatus technical field, is a kind of Digit Control Machine Tool cutterhead specifically.

Background technology

Current Digit Control Machine Tool cutter, only can install two cutting tips, as shown in Figure 1, Figure 2, Figure 3, Figure 4 on its knife bar cutterhead, sequence number 1 is knife bar, and sequence number 2 is blade one, and sequence number 3 is cutterhead, sequence number 4 is blade two, and

sequence number

5,6,7,8 is respectively four basils of blade.This design form makes installed blade can only use the basil on Yi Ge diagonal angle, as the basil of sequence number 5 and sequence number 8, two basils of sequence number 6 and sequence number 7 are idle inoperative, and when two basils of sequence number 5 and sequence number 8 may wear to when ultimate attainment, cutter is scrapped.This just makes blade farthest not utilized, and has caused serious waste, has increased the processing cost of workpiece.

Summary of the invention

For overcoming the deficiencies in the prior art, goal of the invention of the present invention is to provide a kind of Digit Control Machine Tool cutterhead, and the symmetric position behind existing blade installation position designs a blade installation position again, so that the utilization rate of blade reaches maximization.

For achieving the above object, the mount pad one, the mount pad two that on the diagonal angle of the cutterhead of knife bar of the present invention, are designed with respectively two symmetrical blades one, blade two, is characterized in that: mount pad one, mount pad two are designed with mount pad three, mount pad four in the axis centre bilateral symmetry of cutterhead.

The present invention is under the installation form of existing impeller vane, in mount pad one, the rear symmetric position of mount pad two, blade mount pad three, mount pad four have been designed, make blade after the serious wear of original installation position, interchangeable symmetric position extremely thereafter continues to install and use, thereby increased the utilization rate of blade, realized the maximization of blade utilization rate.

The present invention compared with prior art has the following advantages:

1) working ability of blade be can farthest utilize, the waste degree of blade and the processing cost of workpiece reduced;

2) need not change cutter shaft, only need the rotation of change machine tool chief axis reverse, can utilize whole basils position of blade, realize the maximization of blade utilization rate.

Fig. 2 is existing impeller vane mounting structure schematic diagram.

Fig. 3 is four basil schematic diagrames of cutting tip.

Fig. 4 is the side view of Fig. 3.

Fig. 5 is structural representation sketch of the present invention.

The specific embodiment

As shown in Figure 5, on the diagonal angle of the cutterhead 3 of knife bar 1, be designed with respectively mount pad 1, the mount pad 2 10 of two symmetrical blades 1, blade 24, mount pad 1, mount pad 2 10 are designed with mount pad 3 11, mount pad 4 12 in the axis centre bilateral symmetry of cutterhead 3.

When lathe is worked, blade 1, a blade 24 that symmetric position is mount pad 1, mount pad 2 10 on cutterhead 3 is only installed, the a pair of cutting basil of the blade of Dang Zheliangge position, as the sequence number 5 of Fig. 3, sequence number 8 basils, when may wear to the limit and can not be used further to cut, blade 1, blade 24 are unloaded, and attach it to mount pad 3 11, mount pad Si12 position, now only the direction of rotation of machine tool chief axis need be changed into oppositely, can continue to use the basil as the sequence number 6 of Fig. 3, sequence number 7 of blade 1, blade 24 to carry out cutwork.

Claims

1. a Digit Control Machine Tool cutterhead, it is characterized in that: on the diagonal angle of the cutterhead (3) of knife bar (1), be designed with respectively mount pad one (9), the mount pad two (10) of two symmetrical blades one (2), blade two (4), it is characterized in that: mount pad one (9), mount pad two (10) are designed with mount pad three (11), mount pad four (12) in the axis centre bilateral symmetry of cutterhead (3).
