Abstract

The utility model discloses a cutter head used for a numerical control machine tool, belonging to the technical field of machining devices. Opposite angles of the cutter head are respectively provided with a mounting base 1 and a mounting base 2 of a blade 1 and a blade 2 which are symmetrical, and the mounting base 1 and the mounting base 2 are symmetrically provided with a mounting base 3 and a mounting base 4 at the both sides of the center of an axis of the cutter head. According to the utility model, on the basis of the conventional mounting form of the blades of the cutter head, the mounting base 3 and the mounting base 4 of the blades are arranged on the symmetrical positions at the backs of the mounting base 1 and the mounting base 2, so that after the blades are seriously abraded at an original mounting position, the blades are installed on the symmetrical positions at the backs, so that the processing capacity of the blades is utilized to the greatest extent, and the waste degree of the blades and the processing cost of work pieces are reduced; a cutter shaft is not replaced, only a rotating direction of a machine tool spindle is changed, so that all bezel parts of the blades can be utilized to maximize the utilization rate of the blades.

Description

A kind of Digit Control Machine Tool cutterhead

Technical field

The utility model relates to the machining apparatus technical field, is a kind of Digit Control Machine Tool cutterhead specifically.

Background technology

Present Digit Control Machine Tool cutter only can be installed two cutting tips, such as Fig. 1, Fig. 2, Fig. 3, shown in 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 is so that the blade of installing can only use the basil on the diagonal angle, the basil such as sequence number 5 and sequence number 8, two basils of sequence number 6 and sequence number 7 are then by idle inoperative, and when two basils of sequence number 5 and sequence number 8 may wear to when ultimate attainment, cutter is then scrapped.This has been caused serious waste just so that blade can not farthest utilize, and 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 utility model 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, be designed with respectively blade one, the mount pad one of blade two, the mount pad two of two symmetries on the diagonal angle of the cutterhead of knife bar of the present utility model, it 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 utility model is under the installation form of existing impeller vane, blade mount pad three, mount pad four have been designed in mount pad one, mount pad two rear symmetric positions, so that blade is after the serious wear of original installation position, interchangeable extremely thereafter symmetric position continues to install and use, thereby increased the utilization rate of blade, realized the maximization of blade utilization rate.

The utility model 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 utility model.

The specific embodiment

As shown in Figure 5, be designed with respectively blade 1, the mount pad 1 of blade 24, the mount pad 2 10 of two symmetries on the diagonal angle of the cutterhead 3 of knife bar 1, 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, blade 24 that symmetric position is mount pad 1, mount pad 2 10 on the cutterhead 3 only is installed, the a pair of cutting basil when the blade of these two positions, sequence number 5, sequence number 8 basils such as Fig. 3, when may wear to the limit and can not be used further to cut, blade 1, blade 24 are unloaded, and attach it to the position of mount pad 3 11, mount pad 4 12, only need this moment the direction of rotation of machine tool chief axis is changed into oppositely, can continue to use the sequence number 6 such as Fig. 3 of blade 1, blade 24, the basil of sequence number 7 to carry out cutwork.

Claims

1. Digit Control Machine Tool cutterhead, it is characterized in that: be designed with respectively blade one (2), the mount pad one (9) of blade two (4), the mount pad two (10) of two symmetries on the diagonal angle of the cutterhead (3) of knife bar (1), 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).
