Abstract

The utility model relates to a milling cuter used for boring and milling lathe equipment, in particular to a step-shaped scrap division disc milling cutter. Four cutter rods are slidingly installed on four T-shaped grooves respectively arranged on a cutter disc, threaded holes are arranged on the cutter rods which are connected with adjusting bolts through the cutter disc, the cutter rods are driven to move along the axis of the cutter disc by twisting the adjusting the bolts through an internal hexagonal wrench, and scales are arranged on the cutter disc and the cutter rods, so that a user can know the specific positions of the cutter rods relative to the cutter disc conveniently. When the cutter rods are manufactured, the positions for installing blades have micro-difference (1mm) in the radial direction of the cutter disc, the four cutter rods are divided into two groups, a plane is conveniently milled in two layers simultaneously when being milled by adjusting the adjusting bolts, and the thickness of cut layers can be adjusted so as to achieve scrap-division cutting. The step-shaped scrap division disc milling cutter can enable milling force and milling power to be reduced, enlarges the thickness of the cut layers at one time, improves cutting efficiency, and is strong in operation convenience and practicality.

Description

Stepped branch bits dish milling cutter
[technical field]
The stepped branch bits dish milling cutter that the present invention relates to use on the machine tool.
[background technology]
Some milling class lathes such as CNC milling machine, plain-milling machine used clip type dish cutting plate for milling cutters installation site when milling plane is on the same radius of gyration and the same plane of rotation, and can not carry out staged cutting adjustment.It is little to have cutting depth, can not carry out staged cutting, can not once accomplish thick fine finishining, and cutting force and cutting power required during milling are bigger, and characteristics such as it is not steady to have a cutting, and impulsive force is big.
[summary of the invention]
The utility model proposes a kind of dish milling cutter that can carry out the cutting of stepped branch bits.
For solving the problems of the technologies described above; The utility model proposes following solution; Stepped branch bits dish milling cutter; Comprise cutterhead, handle of a knife, knife bar, blade, push type broach screw, buckle, adjustment bolt, screw, it is characterized in that axis direction has T type groove on the described cutterhead, knife bar can slide in T type groove.When adjusting to the right place, knife bar can lock knife bar with housing pin.Described knife bar is according to the difference of when cutting place ladder, and the blade installation site can differ 1~3mm on the direction of cutter rotary radius.
For solving the precise displacement problem of knife bar, on cutterhead and knife bar, be carved with scale, and utilize cursor principle to carry out accurate displacement (the actual displacement precision can reach 0.02mm), thereby the plane of rotation of point of a knife is in same plane when the same ladder of assurance multitool cuts.
Can move easily for the displacement that guarantees knife bar, be provided with the adjustment bolt, only need just can drive knife bar and on the axis direction of cutterhead, move with inner hexagon spanner twisting adjustment bolt.The restriction of the axial displacement of adjustment bolt, the circular hole and the buckle of cutterhead end face capable of using limit.
T type groove number on the cutterhead can change along with the variation of cutter diameter, can adopt the branch of 2,3,4,6 grooves, and the quantity of knife bar is corresponding with it.When adopting 2 grooves, can adopt 2 ladders to cut.Adopt 3 ladders to cut when adopting 3 grooves.Adopt 2 ladders to cut when adopting 4 grooves, this moment 2 is cutter one group, is in same ladder.Adopt 3 ladders to cut when adopting 6 grooves, this moment 2 is cutter one group, is in same ladder.
The ladder degree of depth of cutting can be adjusted easily in actual the use, and the back locking housing pin of adjusting to the right place gets final product., the degree of depth of basecoat ladder just can realize thick fine finishining simultaneously when being adjusted into allowance for finish.
The utility model can be convenient to use in machine tooling, only needs blade is installed, and knife bar is adjusted to the right place; The locking knife bar just can cut; Owing to be to carry out the ladder cutting, contrast common clip type dish milling cutter, can increase cutting depth in the cutting at one time; Improve stock-removing efficiency, easy to operate practical.

[specific embodiment]
Embodiment one
The stepped branch bits dish milling cutter that the utility model proposes; Comprise cutterhead (6), handle of a knife (1), knife bar 1 (7) (38), knife bar 2 (11) (35), blade (10) (14) (33) (36), push type broach screw (9) (13) (34) (39), buckle (15) (23) (27) (29), adjustment bolt (8) (12) (32) (37), screw (16) (17) (18) (22) (26) (28) (30) (31), hexagon socket head cap screw (21), housing pin (2) (3) (4) (5) (19) (20) (24) (25); Cutterhead and handle of a knife are connected through the hole axle in Fig. 1, Fig. 2; And by straight end-face key connection and transmission moment of torsion; Handle of a knife matches with the endoporus of machine tool chief axis, and cutterhead is fixed on the handle of a knife through hexagon socket head cap screw, in Fig. 3, Fig. 4, Fig. 6; Cutterhead is provided with 4 T type grooves can install 4 knife bars respectively; The back side of knife bar is provided with a screwed hole, can be connected with the adjustment bolt installed on the cutterhead, and the adjustment bolt is stuck between buckle and the cutterhead through buckle; And guaranteeing axially to have certain clearance, twisting adjustment bolt just can drive knife bar and produce displacement along the cutter axis direction.Buckle is pressed on the cutterhead through screw.In Fig. 5, be carved with scale respectively on cutterhead and the knife bar body, utilize cursor principle, can make knife bar produce accurate displacement, precision can reach 0.02mm.Adjusting to the right place when knife bar can be through housing pin locking knife bar.In Fig. 6, can see the clip type blade is installed on the knife bar, and screwed hole behind.In Fig. 7, can see that knife bar can be divided into knife bar 1 and knife bar 2 because this cutterhead is installed 4 knife bars, use in pairs, and when using the radius of gyration of knife bar 1 than the big 1mm of the radius of gyration of knife bar 2.Fig. 8 can find out that cutter carries out the situation of stepped cutting.
During work, can be divided into and only carry out roughing or thick fine finishining is once accomplished.When carrying out roughing.The height of adjusting two ladders according to the difference of rapidoprint is between 2~5mm, and use in pairs, only needs the locking knife bar according to the scale cutter back of adjusting to the right place, can carry out cut.When carrying out fine finishining; The height of ladder can be adjusted into about 0.5mm; This moment, roughing (surplus that can be bigger) was carried out on the upper strata of cutter, and lower floor carries out fine finishining, and for improving the surface roughness of part; Blade can adopt the blade with wide sword smoothing effect, improves the surface roughness of part.
