Technical field
The utility model relates to the anchor clamps field, relates in particular to use in a kind of line cutting processing adjustable and has the anchor clamps of short-circuit protection function.
Background technology
The line cutting processing just is being widely used in field of machining as the part of special processing technology.And in wire cutting machine tool practical operation process, anchor clamps are indispensable instruments, and the convenience of its clamping, operability and precision all will directly have influence on the precision of workpiece to be machined.
In present wire cutting technology, the normal cantilever support that adopts, the method for board-like support are carried out clamping to part.This type of clamping method one is to need the part blank size big so that employing pressing plate etc. carry out clamping, and is just comparatively difficult when micro parts or the little part of part processing surplus adopt these class methods to carry out clamping; The 2nd, all need behind each clamping part is carried out centering such as linearity, levelness, this
Procedure requires a great deal of time, and has influenced working (machining) efficiency to a great extent.The 3rd, current line cutting processing can have been accomplished unmanned production, but tending to occur in process drop such as core severs molybdenum filament, the workpiece material distortion causes phenomenons such as short circuit, pinch off molybdenum filament, thereby brings great inconvenience even can cause scrapping of part to follow-up work.
Publication number " CN 2887523Y " in China's utility model application prospectus, name be called " be used for line cutting round piece hole processing clamp " patent disclosure a kind of round piece hole processing clamp, it comprises firm banking, V-type locating piece, V-type sliding shoe, sliding shoe fixed head, T prefix, holding screw, long U type hole.Wherein the V-type locating piece is fixed on the firm banking, the V-type sliding shoe matches with dovetail groove on the firm banking, sliding shoe fixed head and firm banking link, holding screw and V-type sliding shoe link, move the V-type sliding shoe with holding screw, cooperate with threaded hole on the fixed head by holding screw, make the threaded hole self-locking, thereby round piece is carried out clamping.The structure of these anchor clamps is relative complex also, and parts are more, and processing and manufacturing difficulty is bigger, processing parts narrow range and not having molybdenum filament and part corresponding protection function.
Summary of the invention
The technical problems to be solved in the utility model provide a kind of can be on wire cutting machine tool positioning and clamping accurately and fast; also solve the existing in prior technology anchor clamps simultaneously and make difficulty, processing parts narrow range and do not have the adjustable wire cutting short-circuit protection anchor clamps of short-circuit protection function.
The utility model is achieved through the following technical solutions:
A kind of adjustable wire cutting short-circuit protection anchor clamps of the present utility model; it comprises the arm beam; checkout gear; movable clamping device; noncontacting switch; locking device; tensioning apparatus; cantilever beam is anti-" L " type; be that crossbeam and bracketed part are formed; on the crossbeam of cantilever beam, offer the V-structure groove; movable clamping device is located at the rectangle square hole; corresponding with the V-type groove; the V-structure groove is done to cooperate with the bracketed part of this cantilever beam; be used for workpiece clamped and be fixed on the movable clamping device in the described V-structure groove; be opened in locking device on the movable jaw member and finish clamping, be opened in the effect that tensioning apparatus on the movable jaw member and checkout gear are finished short-circuit protection workpiece.
Described V-structure both sides are isosceles limits, by tangent with the round piece of different-diameter, can be so that the bisector of V word angle be crossed the center of circle of round piece, and from two lines at the center of circle of round piece and point of contact vertical with the isosceles limit.The two sides of V-structure are vertical with the cantilever beam bottom surface.
Described movable clamping device comprises: clamping part and retaining parts.Wherein, clamping part and retaining parts all have rectangular opening, and both can be free to slide at the bracketed part of cantilever beam, make matched in clearance, thereby realize the controllability of clamping part dimension.Clamping part contacts with clamping workpiece retention wire to guarantee the reliability of clamping precision.After the effect of retaining parts is the locking device effect, make the bracketed part of its rectangular opening side and cantilever beam that " dieback " take place thus phenomenon realizes the clamping of part.
Described locking device is to clamp adjusting knob, and what realize clamping is threaded portion, and adjusting knob is the annular knurl at concavo-convex interval.Clamp adjusting knob and do to cooperate with the screwed hole on being opened in the retaining parts, thereby withstand the clamping that clamping part is realized part by the screw head end face by screw thread.
Described tensioning apparatus is a spring, and it is installed on the inside, two holes that is opened on clamping part and the retaining parts.When workpiece drop or because of the material change that causes the clamping workpiece position that deforms be that tensioning apparatus can make clamping part do corresponding change in displacement.
Described checkout gear is noncontacting switch and adjustment screw, and wherein: noncontacting switch is by in the screwed hole of thread connection on being opened in the retaining parts, and links to each other with fracture of wire protection switch in the lathe internal circuit.Adjustment screw is also by in the screwed hole of thread connection on being opened in clamping part.Do the change in displacement of trace when clamping part after, noncontacting switch can obtain corresponding signal, makes lathe generation stubble warning device, thereby realizes the function of short-circuit protection.
The beneficial effect of a kind of adjustable wire cutting shield jig of the present utility model is: reasonable in design; simple in structure; easily manufactured; can realize quick, accurate positioning and clamping to workpiece; and can effectively prevent short circuit rollback, fracture of wire phenomenon; prolong the service life of molybdenum filament, improve the machining accuracy of part, promoted the unmanned production in the line cutting processing.
