Abstract
The invention discloses an end arc punching tool. The end arc punching tool comprises a bottom plate fixed on a machine tool, and a positioning block positioned on the bottom plate and used for clamping a workpiece, wherein a vertical cutter hole and a horizontal workpiece hole of which axes are vertical and intersected with each other are formed in the positioning block. The end part of the workpiece to be punched is put into the horizontal workpiece hole to circumferentially position and clamp the workpiece, and a cutter on a punching machine downwardly enters the vertical cutter hole to punch the end part of the workpiece. The end arc punching tool is specially used for fixing the workpiece so as to punch an arc at the end part of the workpiece.
Description
Technical field
The present invention relates to a kind of frock folder, particularly a kind of frock in pipe fitting end arc making.
Background technology
Pipe fitting such as square tube, pipe etc. are conventional structural members; use as connection or keeper as square tube usually can be used in frame of motorcycle; for the ease of welding or installation; usually the end of square tube to be processed into the circular arc of indent; adopt processes this arc in square tube end along the mode that camber line progressively cuts more at present, and the curved surfaces after cutting is more smooth, but cutting speed is slower; particularly for the weldment that roughness requirements is not high, adopt cutting processing arc production efficiency low.For this reason, the present inventor has invented a kind of method utilizing punch press to process arc, and is arranged on the mold of press machine by punching tool, once punches out arc at pipe fitting end by cutter undershoot.For this reason, a kind of frock being specifically designed to fixation workpiece and pipe fitting is also needed.
Summary of the invention
In view of this, the technical problem to be solved in the present invention is to provide a kind of end arc making frock, is specifically designed to fixation workpiece to realize at workpiece end Punching Technology arc.
Arc making frock in end of the present invention, comprises for being fixed on base plate on lathe and being positioned at the locating piece for clamping workpiece on base plate, and described locating piece is provided with axes normal and crossing vertically walks tool bore and horizontal workpiece hole.
Further, described locating piece is provided with the locating part for location, workpiece front end, described locating part comprises a gag lever post and is positioned at the projection that this gag lever post raises up, described gag lever post to be connected on locating piece and to be positioned at the below in horizontal workpiece hole, described projection near gag lever post free end and workpiece front end is withstood.
Further, described locating piece is provided with the clamp system will clamped about workpiece, institute's clamp system comprises the left and right pressing plate that is positioned at horizontal location hole and to be connected on left and right pressing plate and to extend to the left and right slide bar of locating piece outside, described locating piece is circumferentially with left and right pilot hole for left and right slide bar, described left and right pilot hole, be interiorly installed with left and right axle sleeve respectively, described left and right slide bar, respectively with left and right axle sleeve, be slidably matched, described left and right axle sleeve and left and right pressing plate, between be arranged with left and right stage clip.
Beneficial effect of the present invention: arc making frock in end of the present invention, comprises for being fixed on base plate on lathe and being positioned at the locating piece for clamping workpiece on base plate, and described locating piece is provided with axes normal and crossing vertically walks tool bore and horizontal workpiece hole.To treat that the end of arc making workpiece is placed in horizontal workpiece hole, complete workpiece circumference positioning and clamping, be positioned at cutter on punch press and enter vertically to walk tool bore and complete Punching Technology to workpiece end downwards.This frock is specifically designed to fixation workpiece to realize at workpiece end Punching Technology arc.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is structural representation of the present invention;
A-A cutaway view Amplified image in Fig. 2 Fig. 1;
Fig. 3 is the shape figure thrusting rear tubular member.
Detailed description of the invention
Below with reference to accompanying drawing, the present invention is described in detail, as shown in the figure: the end arc making frock of the present embodiment, comprise for the locating piece 2 being fixed on base plate on lathe 1 and be positioned at for clamping workpiece on base plate, described locating piece 2 is provided with axes normal and crossing vertically walks tool bore 2a and horizontal workpiece hole 2b.Base plate 1 is fixed by the clamping part 52 on its workbench 51 by punch press, and require that tool bore 2a is just to the below of the cutter 53 on punch press, to treat that the end of arc making workpiece 6 is placed in the 2b of horizontal workpiece hole, complete workpiece circumference positioning and clamping, cutter 53 has corresponding to arc to be processed curved blade, cutter 53 downwards and enter vertically to walk tool bore 2a and complete and thrust processing to workpiece end, one-step punching just can process arc at pipe fitting end, as shown in Figure 3, the weldment not high concerning fracture roughness requirements, to enhance productivity.
As the further improvement of technique scheme, described locating piece 2 is provided with the locating part 3 for location, workpiece front end, described locating part 3 comprises a gag lever post 31 and is positioned at the projection 32 that this gag lever post 31 raises up, described gag lever post 31 to be connected on locating piece 2 and to be positioned at the below of horizontal workpiece hole 2b, described projection 32 near gag lever post 31 free end and workpiece front end is withstood, be convenient to the front and back of workpiece to position.
In order to by location more firm for workpiece, the clamp system 4 clamped about locating piece 2 being provided with by workpiece, institute's clamp system 4 comprises the left and right pressing plate 41,42 being positioned at horizontal location hole, left pressing plate 41 is connected with left slide bar 43, right pressing plate 42 is connected with right slide bar 44, and described left and right slide bar 43,44 all extends to outside locating piece 2.On locating piece 2, corresponding left slide bar 43 is circumferentially with left pilot hole 21, corresponding right slide bar 44 is circumferentially with right pilot hole 22, the left axle sleeve 23 be placed on outside left slide bar 43 is provided with in left pilot hole 21, the right axle sleeve 24 be placed on outside right slide bar 44 is provided with in right pilot hole, left, right slide bar 43, 44 respectively with a left side, right axle sleeve 23, 24 are slidably matched, left stage clip 45 is provided with between left axle sleeve 23 and left pressing plate 41, right stage clip 46 is provided with between right axle sleeve 24 and right pressing plate, on a left side, right stage clip 45, the effect bottom left of 46, right pressing plate 41, the left and right sides of workpiece clamps by 42 respectively, fixing more firm, a left side is pulled out after arc making completes, right slide bar 43, 44 make left and right pressing plate 41, 42 leave workpiece, so that get workpiece.
