Abstract

The invention discloses a stamping machine tool with a flexible workpiece positioning device, which comprises an upper die and a lower die. The stamping machine tool is characterized in that the lower die is arranged on a cylindrical die holder which is arranged on an operating table of the machine tool, and the bottom of the die holder is connected with a positioning device which controls the die holder to move vertically. Two positioning sliders are arranged on two sides of the die holder and on the tabletop of the operating table respectively, and provided with semi-frustum shaped grooves in symmetry. The combined positioning sliders can enclose a cone frustum shaped groove with the upper bottom larger than the lower bottom, and the diameter of the lower bottom of the cone frustum shaped groove is equal to that of the die holder. The positioning device and the positioning slider are respectively connected with a control system. The stamping machine tool with the flexible workpiece positioning device is applicable to stamping of small round workpiece sheets in various dimensions, a workpiece can be clamped in the groove of the positioning slider under the action of vertical moving of the lower die holder, the workpiece can be effectively stabilized during stamping, and accordingly workpiece machining precision can be improved, and machining error probability can be lowered.

Description

Technical field
The invention belongs to part processing and make the field, specifically is a kind of press machine that has flexible Working piece positioning device, is applicable to the small-sized disk shape part of processing.
Background technology
Prior art keeps in punching course firmly in order to guarantee part when part is carried out punch process, tends on workbench, be provided with the position that clamping device, location nail or locating hole limit workpiece to be processed; But for the less part of some volumes, generally be difficult to be provided with clamping device, and also do not have the unnecessary clout nail that is positioned fixing; If locating hole is set,, only be applicable to the part of a certain fixed dimension though its steadiness is good; The processing homologous series are the part of different size but, just need reprocess out a locating hole in addition, and not only consumptive material is more; Also waste man-hour, be unfavorable for improving the production efficiency and the economic benefit of factory.
Summary of the invention
Technical purpose of the present invention is the defective that overcomes prior art, and a kind of press machine that has flexible Working piece positioning device is provided, and is applicable to the small-sized disk shape part of processing different size.
Technical scheme of the present invention is:
A kind of press machine that has flexible Working piece positioning device is provided with upper die and lower die, it is characterized in that:
Said counterdie is arranged at a cylindrical die holder center, and said die holder is arranged on the workbench of lathe, and the die holder bottom is connected with the positioner that the control die holder moves up and down;
On the table top of said workbench; The both sides that are positioned at said die holder respectively are provided with a slip locating piece; Be arranged with the groove of half taper type on the said slip locating piece; The taper type groove upper bottom surface that said slip locating piece surrounds after merging is greater than bottom surface, and the diameter of its bottom surface equals the diameter of said die holder;
Said positioner is connected with the control system respectively with the slip locating piece.
Further technical scheme:
The present invention also comprises one group of sender unit and signal receiving device; Be preferably light and transmit and receive device; Said sender unit is arranged at the bottom of slip locating piece groove; Said signal receiving device is arranged at the outside top of said slip locating piece, and said signal emission dress, signal receiving device are connected with said control system.
Said slip locating piece is provided with a protective plate on the top of sender unit; The projection of the free-ended outer of said protective plate on direction straight down drops on outside the said locating piece groove floor scope; After promptly two slip locating pieces merged, the distance between two protective plates can not be greater than the diameter of said counterdie die holder.
Said positioner comprises a pneumatic equipment and the connecting rod that is connected with said die holder.
Said protective plate is provided with plurality of opening.
The present invention is placed on disk shape part on the die holder of said counterdie earlier, according to the size of part round diameter in use; The control die holder moves down; Making part be in the position of the frustum groove cross section identical with its diameter, is that the center merges with the die holder through control system control slip locating piece then, and the while is because of the effect of groove; Automatically its center stamping position is located in the position of adjustment part.When two slip locating pieces are closed fully; When the counterdie die holder is in the frustum groove that forms after two slip locating pieces merge; Part has just covered the signal that sender unit is outwards launched in the groove fully; Signal receiving device does not receive after the signal, and the control system controls patrix automatically part is carried out punching press, and said groove plays the effect of locating element in punching course simultaneously.
The present invention has reduced the replacing of tool in the part processing, has reduced production cost, has also improved operating efficiency simultaneously greatly.
Description of drawings
Fig. 1 is the structural representation of counterdie die holder and slip locating piece;
Fig. 2 is a cross-sectional view of the present invention;
Fig. 3 is the local structure for amplifying sketch map of Fig. 2.
The specific embodiment
In order to illustrate technical scheme of the present invention and technical purpose, the present invention is done further introduction below in conjunction with the accompanying drawing and the specific embodiment.
As shown in the figure; A kind of press machine that has flexible Working piece positioning device; Be provided with upper die and lower die; Said counterdie is arranged at cylindrical die holder 2 center positions, and said die holder 2 is arranged on the workbench of lathe, and die holder 2 bottoms are connected with the pneumatic power positioner that control die holder 2 moves up and down through connecting rod.
On the table top of said workbench; The both sides that are positioned at said die holder 2 respectively are provided with a slip locating piece 1; Be arranged with the groove of half taper type on the said slip locating piece 1; The taper type groove upper bottom surface that surrounds after said slip locating piece 1 merges is greater than bottom surface, and the diameter of its bottom surface equals the diameter of said die holder.
Said pneumatic power positioner is connected with the control system respectively with slip locating piece 1.
The bottom of the groove of said slip locating piece 1 is provided with optical signal launcher 13; Accordingly; Above the outside of said slip locating piece 1, be provided with light signal receiving; It can be located on counterdie lathe or the patrix machine tool, and the emission of said optical signal adorns 13, light signal receiving is connected with said control system.
Said slip locating piece 1 is provided with a protective plate 11 on the top of sender unit 13; The projection of said protective plate 11 free-ended outers on direction straight down drops on outside the said slip locating piece 1 groove floor scope; As shown in Figure 3; And said protective plate 11 is provided with plurality of opening, is used for passing through of light signal.
