Abstract
The utility model relates to a large taper cutting line frame structure for a linear cutting machine. The lower side of an upper linear arm is provided with a mopping plate and a holder in U direction and V direction. The holder and the lower linear arm are respectively provided with an upper rotary shaft, a lower rotary shaft, an upper guide wheel head, and a lower guide wheel head and are connected together via the guide cover of a guide column. An upper guide wheel uses a double guide wheel structure, and the upper linear arm can use the up-down type design. The structural design removes two theoretical errors existing in the structure of a traditional taper cut line frame. The utility model has good structural rigidity and can realize taper cutting from 0 to 45 DEG under the allowed condition within space range. The thickness range of a processing work piece can reach from 0 to 400 mm.
Description
The utility model relates to the wire frame structure on the electric spark linear cutting machine, especially can carry out the wire frame structure of tapering cutting.
The wire frame structure of the carried out tapering cutting of being adopted on quick wire electrical discharge machine tool at present, is mainly rocking lever formula (seeing " electric machining " 1994 the 3rd phases " error analysis of electric spark linear cutting machine swing type taper guide frame ").This structure exists two kinds of theoretical errors in the tapering cutting process, that is: its circular motion was the transformed error that produces therefrom by due to the rectilinear motion of screw mandrel when displacement error that produces owing to the point of contact change in location of wire electrode on guide wheel when guide wheel moves forward and backward and guide wheel swung; And because coil holder will be done whole swing, so the accuracy of manufacture is had relatively high expectations and structural rigidity is relatively poor.Above defective all is very limited machinable tapering and thickness of workpiece.
The purpose of this utility model be to provide a kind of when tapering cuts gear shaper without theoretical errors and structural rigidity better, tapering line of cut shelf structure that machinable tapering and thickness of workpiece are improved greatly.
Solution of the present utility model is: below the arm of reaching the standard grade, install U to planker and V to planker, the below of planker connects retainer; Last rotating shaft adopts the mode of bearing location to be installed in the retainer, and rotating shaft can freely be rotated around its axis; The front end of last rotating shaft is the upper block head fixedly, and upper block adopts two Guiding wheel structures, is installed in the upper block head; The rear end of last rotating shaft adopts the mode of hinge to link to each other with the upper end of guide pillar guide pin bushing, and the lower end of guide pillar guide pin bushing then links to each other with the rear end of lower rotary shaft in the mode of hinge; Lower rotary shaft also adopts the mode of bearing location to be installed in the arm that rolls off the production line, and lower rotary shaft can freely be rotated around its axis, and the front end of lower rotary shaft is the lower tumbler head fixedly.
On the basis of such scheme, the arm of reaching the standard grade also can adopt the mode of screw mandrel to be installed on the column, and locatees with locking member.
Accompanying drawing 1. the utility model structural representations.
Accompanying drawing 2. guide wheels move forward and backward position view.
Accompanying drawing 3. guide wheel left and right sides inflection point schematic diagrames.
From accompanying drawing 1 as seen, the U that arm lengthwise movement along the line is installed below the arm 2 of reaching the standard grade is to planker 11, and the V that U then installs arm transverse movement along the line to the below of planker is to planker 12, and retainer 4 is fixed on the below of V to planker, can move with planker.Wire electrode 1 enters upper block head 5 through the below of planker, enters lower tumbler head 7 after walking around upper block 6, walks around lower tumbler 8 again after the arm 10 that rolls off the production line returns.Last rotating shaft 13, lower rotary shaft 9 all adopt the mode of bearing location to be installed in respectively in the retainer and the arm that rolls off the production line, and upper and lower rotating shaft can freely be rotated around axis separately.Upper and lower guide wheel head is installed in the front end of upper and lower rotating shaft respectively, can freely rotate with upper and lower rotating shaft.Organically link together by guide pillar guide pin bushing 14 between the upper and lower rotating shaft, each tie point all adopts the mode of hinge, and guide pillar guide pin bushing retractable, makes three's relative motion consistently freely.U is driven by stepper motor respectively to planker to planker and V, drives retainer and the first-class moving linearly together of upper block.When carrying out the tapering cutting, the U of wire electrode drives upper block head by U to planker to tilting and moves forward and backward and realize, the V of wire electrode to tilt by V to planker drive upper block head move left and right simultaneously upper and lower guide wheel head separately more than, lower rotary shaft is that the center produces deflection automatically and realizes.At this moment, each pin joint of upper and lower rotating shaft and guide pillar guide pin bushing also produces relative deflection, and the guide pillar guide pin bushing carries out stretching motion, with guarantee upper and lower guide wheel head move and deflection is accomplished.From accompanying drawing 2 as can be seen, the point of contact position of wire electrode on guide wheel still changed when guide wheel moved forward and backward, but owing to adopted two Guiding wheel structures, when the position, point of contact when A, B point changes to C, D point or E, F point, actual tangent position and theoretical tangent position formation two intersection point G, H, promptly exist one and cross the plane MN that G, H are ordered, on this plane, because the theoretical error that the point of contact change in location is produced is zero.Therefore, in reality processing, just can eliminate U on the MN plane to theoretical error as long as keep the cutting edge face of mould to be positioned at.From accompanying drawing 3, then as can be seen, when guide wheel is done move left and right and deflection, itself realize, therefore do not have the transformed error of circular arc and straight line, that is V also is zero to theoretical error by rectilinear motion.
Because the utility model does not need coil holder to do whole swing, therefore whole coil holder (between especially upper and lower line arm and the column) can have higher rigidity, and structural stability is increased.At this moment, can adopt the mode of screw mandrel to be installed on the column 3 on the arm of reaching the standard grade, and locking members such as employing trip bolt are located on column, make the arm of reaching the standard grade can be easily along column move up and down (this moment, the guide pillar guide pin bushing also carried out stretching motion) and location, cut with the workpiece of realization, and can realize the workpiece of big thickness is cut different-thickness.
In sum, the utility model has been eliminated two kinds of theoretical errors that exist in the present general wire cutting machine tool tapering line of cut shelf structure on structural design, and rational in infrastructure, easy and simple to handle, therefore under the condition that spatial dimension allows, can realize the tapering cutting of 0-45 ° of scope.Better, the stability increase of structural rigidity simultaneously, the arm of therefore reaching the standard grade can adopt the lift design, makes the thickness range of processing work reach 0-400mm.
