Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
A kind of plastic material deep trouth process tool, including as shown in Figure 1, Figure 2 with the cutter hub shown in Fig. 3, cutter hub is by the He of knife bar 1
Cutter head 2 is constituted, and cutter head 2 is connected to knife bar lower end, and cutter head 2 is integrally formed with knife bar 1, and cutter head 2 is in tabular, cutter head 2
Obverse and reverse is platen surface, and the right flank of cutter head 2 is the knife back 21, under the left surface of cutter head 2 is cutting face 23, cutter head 2
Hold as cutter head end face 24, the intersection in cutter head end face 24 and cutting face 23 is blade 25, blade 25 keeps acute angle shape (not rounding
Angle), plastic material is planed so as to processing groove by blade 25 in process, the length of blade 25 is equal to the thickness of cutter head 2, knife
First 2 width (vertical range of blade 25 to the knife back 21) is more than 10 times, such as width of cutter head 2 with the ratio of edge length
(length of blade 25) is 1mm, and the width of cutter head 2 is 23mm, the length (vertical range of blade 25 to knife bar 1) of cutter head 2 with
The ratio of edge length is more than 10 times, and such as length of cutter head 2 is 30mm, can so process not only narrow but also deep groove.
Because in process, be plastic material with respect to the straight reciprocating motion of cutter head 2, for the ease of return, the knife of cutter head 2
End surface 24 is inclined-plane, particularly, and the angle of cutter head end face 24 and the knife back 21 is 95 °.Cutting face 23 should also be inclined-plane so that
The angle of blade 25 is smaller, more conducively cuts, however, to ensure that the not breaking of cutter head 2, so the angle of blade 25 also should not be too small, most
Good to meet, cutter head end face 24 and the angle in cutting face 23 are more than 60 °, and cutter head end face 24 and the angle in cutting face 23 are less than
180 ° (angle of-cutter head end face 24 and the knife back 21).In order to ensure the intensity of cutter head 2, good stress performance during cutting, cutting face 23 is simultaneously
Knife bar 1 is not extended directly into, but also has one section of extended surface 22, cutting face 23 and extended surface between cutting face 23 and knife bar 1
22 natural arc transitions.
As shown in Figure 1, 2, 3, knife bar 1 is a cylinder, and the side of cylinder cuts knife bar stationary plane 11, knife bar 1
Lower end opens up a step groove, forms dress knife rectifying plane 12, because cutter head is relatively thin, is not suitable for being corrected with cutter head 2, opens up dress
Knife rectifying plane 12 is used for clamping to correcting knife face during planer.Filling knife rectifying plane 12 should be parallel to cutter head 2, knife bar stationary plane
11 are preferably parallel to cutter head 2, and the quantity of knife bar stationary plane 11 can also be two.In order to protect blade 25, blade 25 without departing from
The extended surface of knife bar external cylindrical surface, the knife back 21 is flushed with knife bar external cylindrical surface.
The width of cutter head 2 of the present utility model is wide more than edge length, during processing, good stress performance.
For the ease of quick-clamping knife bar, and ensure clamping stability, reduce the knife that quivers, the utility model is made to hilt
Improve.As shown in Figure 4 and Figure 5, hilt includes inner cylinder 3, outer barrel 4 and compact heap 5, and endoporus and the knife bar 1 of inner cylinder 3 coordinate, inner cylinder 3
Side wall open up compact heap groove 31 just to knife bar stationary plane 11, the both sides of compact heap groove 31, which are provided with side channel 32, side channel 32, pacifies
Shock mount 34, spring 34 is separated with compact heap groove 31 by block 33, and the effect of block 33 makes to fix spring 34, makes spring 34 not
Compact heap groove 31 can be entered, the left surface of compact heap 5 is parallel with knife bar stationary plane 11, the both sides of compact heap 5 are provided with side plate 51, side
Plate 51 is stretched into side channel 32 and offseted with spring 34, and the right surface of compact heap 5 is one section of conical surface, upper endoporus and the inner cylinder 3 of outer barrel 4
Epimere screw thread coordinate, the lower endoporus of outer barrel 4 is the taper hole with the cone match of compact heap 5.In clamping process, as long as rotation is outer
Cylinder 4, during outer barrel 4 is moved downward, its taper hole extruding compact heap 5 makes compact heap 5 be slided to the direction of knife bar 1, so as to compress knife
Bar.In unloading process, spring 34 plays a part of resetting compact heap 5.
In use, correcting the dress knife rectifying plane 12 on cutter on lathe.Machine tool chief axis locking, does not do and rotates；Adding
The plastic material product of work is fixed on platen face, and machine tool chief axis does the unidirectional motions of X or Y, with a kind of planing
Mode processes the narrow deep trouth on product.
Consider the characteristic of lathe and the shape of cutter head 2, cutter described in the utility model does not do heavy cut, therefore mainly for
Plastic material.Plastic material product narrow but also deep groove processing not only is realized, breaking is difficult, and cutter clamping is stable, and antidetonation is prevented
Quivering property is good.
