Abstract

The invention discloses a positioning fixture for bars. The fixture comprises a fixed part and a movable part, wherein the movable part can carry out rotary open-close motion around the fixed part through a connecting component, a positioning plate is embedded in the movable part, a rotating shaft which transversely passes through the two end parts of the positioning plate and is connected to the inside of the movable plate is set, three pairs of threaded through holes are uniformly formed on the positioning plate and the fixed part along the circumferential direction of the fixture, screws which can be screwed in the threaded through holes are arranged, and after a bar is placed in the fixture, the movable part and the fixed part are buckled, and the positioning plate and the screws are adjusted so as to ensure the standing of the bar, so that the machining precision is high, and the machining quality is good.

Description

A kind of tool locating fixture of rod member
Technical field
the present invention relates to a kind of tool locating fixture of rod member.
Background technology
the tool locating fixture of existing rod member, there is the inner chamber be connected with outside, fixture itself adopts integrated design, the internal chamber wall of fixture is smooth, during use, rod member is put into the inner chamber of fixture, then operate lathe to process rod member, have two shortcomings like this, one is can produce collision phenomenon with fixture unavoidably when putting into workpiece, easily causes damage to a certain degree to workpiece, reduce the quality of work pieces process, two is cannot regulate the angle of workpiece, can not guarantee that workpiece is in vertical state, have impact on the machining accuracy of workpiece.
Summary of the invention
the object of this invention is to provide the tool locating fixture improving the crudy of rod-shaped workpiece and the rod member of machining accuracy.
for achieving the above object, the invention provides a kind of tool locating fixture of rod member, comprise base, be arranged on the clamp system for clamping described rod member of described base top, for locating the detent mechanism of described rod member, described clamp system comprises fixed part, be arranged on the connector of described fixed part side, side is connected to the movable part of open and close movement that described connector can rotate relative to described fixed part, at described fixed part, arc groove is offered respectively in the face that described movable part is relative, according to described movable part folding described in positioning fixture have open and fasten two states, when described positioning fixture is in open configuration, described fixed part, the opposite side of described movable part is separated, described fixed part, the opening can putting into rod member is formed between described movable part, when described positioning fixture is in buckling state, described fixed part, the opposite side of described movable part fits, arc groove described in a pair draws close the circular hole formed for clamping described rod member mutually.
preferably, described detent mechanism comprises vertically direction and is embedded in location-plate in described movable part, the both ends be horizontally through in described location-plate are connected to the rotating shaft in described movable part, offer and be horizontally through described location-plate, three double thread through holes of described fixed part, often pair of described tapped through hole is symmetrical arranged up and down, three pairs of described tapped through holes are evenly distributed in the circumferential direction of described positioning fixture, the screw rod that shape and described tapped through hole match is set, in tapped through hole described in the head precession of described screw rod, at the afterbody of described screw rod, between the outer circumference surface of described positioning fixture, locking nut is set.
preferably, the middle part of the periphery of described tool locating fixture has the annulus of circumference, described annulus is protruding in the stretch out formation a pair of the opposite side of described fixed part, the opposite side of described movable part, offer fixed part groove, movable part groove respectively at the outer middle side part of described a pair projection, the locking member that can rotate in the horizontal direction be connected in described fixed part groove is set.
because technique scheme is used, the present invention compared with prior art has following advantages and effect: fixture is separately designed to fixed part, movable part, fixed part, connected by connector between movable part, movable part does open and close movement by connector around fixed part, so that pick and place rod member to be processed, vertically direction is set and is embedded in location-plate in described movable part, and the both ends be horizontally through in location-plate are connected to the rotating shaft in movable part, circumferential direction along fixture is even must at location-plate, fixed part is offered three double thread through holes, every double thread through hole is all be symmetrical arranged up and down, arranging can the screw rod of precession tapped through hole, when fixture put into by rod member, can rotate around the axis by regulating location-plate, screw rod stretches into the length of tapped through hole to regulate the vertical bury pipe of rod member, which enhance crudy and the machining accuracy of rod-shaped workpiece.
accompanying drawing illustrates:
accompanying drawing 1 is perspective view when the present invention is in open configuration;
accompanying drawing 2 is perspective view when the present invention is in buckling state.
detailed description of the invention:
shown in Figure 1, base 1 plays supporting function to positioning fixture of the present invention, at the top of base 1, fixed part 2 is set, movable part 3, fixed part 2, movable part 3 is connected by connector 4, movable part 3 to rotate around fixed part 2 by connector 4 and then realizes opening and conjunction of positioning fixture, at fixed part 2, the face that movable part 3 is relative is offered a pair arc groove as 5, during operation, first by movable part 3 rotating opening, rod member to be processed is put into fixture, then movable part 3 is rotated fastening, now, a pair arc groove draws close the circular hole forming collecting rod member to be processed mutually as 5, the location-plate 6 be embedded in movable part 3 is set, the both ends be horizontally through in location-plate 6 are connected to the rotating shaft 7 in movable part 3, location-plate 6 can 7 rotations doing certain angle around the shaft, in order to adjust the vertical bury pipe of rod member to be processed, circumferential direction along positioning fixture is even must at location-plate 6, fixed part 2 is offered three double thread through holes as 8, every double thread through hole is as 8 being all symmetrically arranged up and down.
shown in Figure 2, the middle part outwardly convex of the outer circumference surface of positioning fixture forms annulus 9, annulus 9 can hold location-plate 6 by ecto-entad in circumferential direction, arrange can precession tapped through hole if the screw rod of 8 is as 12, at screw rod as arranged locking nut between 12 and the outer circumference surface of positioning fixture, when rod member to be processed is positioned, the angle of adjustment location-plate 6, adjust three pairs of screw rods as 12 through the length of tapped through hole as 8 heads exposed afterwards, can guarantee that rod member to be processed is in vertical state, annulus 9 is at the opposite side of fixed part 2, the opposite side of movable part 3 stretches out formation a pair projection as 10, a pair groove is offered respectively as 13 at a pair protruding outer middle side part as 10, the locking member 11 that can rotate in the horizontal direction is set in the groove of fixed part 2, when locating furniture and being in buckling state, rotation lock gripping members 11, namely locking member 11 is clamped in the groove of movable part 3, so namely, secure workpiece to be processed.
