Description
Technical field
The present invention relates to a kind of tool locating anchor clamps of rod member
Background technology
The tool locating anchor clamps of existing rod member, has the inner chamber that is connected with the outside, anchor clamps itself adopt integrated design, the internal chamber wall of anchor clamps is smooth, during use, rod member is put into the inner chamber of anchor clamps, then operating lathe processes rod member, have like this two shortcomings, the one, when putting into workpiece unavoidably can and anchor clamps produce collision phenomenon, easily workpiece is caused to a certain degree damage, reduced the quality of workpiece processing, the 2nd, can't regulate the angle of workpiece, can not guarantee that workpiece is in vertical state, has affected the machining accuracy of workpiece
Summary of the invention
The tool locating anchor clamps that the purpose of this invention is to provide the rod member of the crudy that improves rod-shaped workpiece and machining accuracy.
For achieving the above object, the invention provides a kind of tool locating anchor clamps of rod member, comprise base, be arranged on the clamp mechanism that is used for the described rod member of clamping of described base top, be used for locating the detent mechanism of described rod member, described clamp mechanism comprises fixed part, be arranged on the connector of described fixed part one side, one side is connected on the described connector can be with respect to the rotate movable part of open and close movement of described fixed part, at described fixed part, offer respectively arc groove on the relative face of described movable part, have according to the described positioning fixture of folding of described movable part and to 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, form the opening that to put into rod member between the described movable part, when described positioning fixture is in buckling state, described fixed part, the opposite side of described movable part fits, and a pair of described arc groove is drawn close the circular hole that is formed for the described rod member of clamping mutually.
Preferably, described detent mechanism comprises along vertical direction and is embedded in location-plate in the described movable part, be horizontally through both ends in described location-plate and be connected to rotating shaft in the described movable part, offer and be horizontally through described location-plate, three double thread through holes of described fixed part, every pair of described tapped through hole is symmetrical arranged up and down, three pairs of described tapped through holes are evenly distributed on the circumferential direction of described positioning fixture, the screw rod that shape and described tapped through hole are complementary is set, in the described tapped through hole of 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 anchor clamps has circumferential annulus, described annulus stretches out at the opposite side of the opposite side of described fixed part, described movable part and forms a pair of projection, offer respectively fixed part groove, movable part groove at the outer middle side part of described a pair of projection, the locking member that can rotate in the horizontal direction that is connected in the described fixed part groove is set.
Because technique scheme is used, the present invention compared with prior art has following advantages and effect: anchor clamps separately are designed to fixed part, movable part, fixed part, connect by connector between the movable part, movable part can be done open and close movement around fixed part by connector, so that pick and place rod member to be processed, arrange along vertical direction and be embedded in location-plate in the described movable part, and be horizontally through both ends in location-plate and be connected to rotating shaft in the movable part, along the circumferential direction of anchor clamps is even must be at location-plate, offer three double thread through holes on the fixed part, every double thread through hole all is to be symmetrical arranged up and down, arrange can the precession tapped through hole screw rod, when rod member is put into anchor clamps, can rotate around the axis by regulating location-plate, the length that screw rod stretches into tapped through hole is regulated the vertical degree of rod member, has improved like this crudy and the machining accuracy of rod-shaped workpiece.
Description of drawings:
Perspective view when accompanying drawing 1 is in open configuration for the present invention;
Perspective view when accompanying drawing 2 is in buckling state for the present invention.
The specific embodiment:
Referring to shown in Figure 1,1 pair of positioning fixture of the present invention of base plays supporting function, 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 can rotate and then realize opening and closing of positioning fixture around fixed part 2 by connector 4, at fixed part 2, offer a pair of arc groove such as 5 on the relative face of movable part 3, during operation, at first with movable part 3 rotating opening, rod member to be processed is put into anchor clamps, then movable part 3 is rotated and fasten, at this moment, a pair of arc groove is mutually drawn close such as 5 and is formed the circular hole of accommodating rod member to be processed, setting is embedded in the location-plate 6 in the movable part 3, be horizontally through both ends in location-plate 6 and be connected to rotating shaft 7 in the movable part 3, location-plate 6 can be around the shaft 7 rotations of doing certain angle, in order to adjust the vertical degree of rod member to be processed, along the circumferential direction of positioning fixture is even must be at location-plate 6, offer three double thread through holes on the fixed part 2 such as 8, every double thread through hole all is symmetrically arranged up and down such as 8.
Referring to shown in Figure 2, the middle part of the outer circumference surface of positioning fixture outwards convexes to form annulus 9, annulus 9 can be held location-plate 6 by ecto-entad on circumferential direction, arrange can the precession tapped through hole such as 8 screw rod such as 12, screw rod as 12 and the outer circumference surface of positioning fixture between locking nut is set, when rod member to be processed is positioned, adjust the angle of location-plate 6, adjust three pairs of screw rods and pass tapped through hole such as the length of 8 heads that expose afterwards such as 12, 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 and forms a pair of projection such as 10, offer respectively a pair of groove such as 13 in a pair of projection such as 10 outer middle side part, the locking member 11 that can rotate in the horizontal direction is set in the groove of fixed part 2, when location furniture is in buckling state, rotation lock part 11, locking member 11 namely are clamped in the groove of movable part 3, have so namely fixed workpiece to be processed
