Description
Technical field the utility model relates to a kind of jig, especially a kind of small-sized jig that is used to grind micropore wire-drawing die and small-sized cylindrical band hole workpiece.
Background technology is present, and the mode of being installed of micropore wire-drawing die attrition process has two kinds, and the one, grind with the mode of the artificial hand rest mould of tradition.But this mode is higher to workman's specification requirement, and the processing precise degree can not guarantee, and labour intensity is big, and production efficiency is low.Another kind of mode is to use jig such as scroll chuck that mould is installed.This mode seems too heavy because the chuck volume and weight is bigger when workpiece such as attrition process micropore wire-drawing die, inertia force is bigger, and machining accuracy is difficult for guaranteeing.Moreover, jigs such as scroll chuck are not very convenient when similar miniature parts such as mounting or dismounting micropore wire-drawing die yet, and efficient is not high; And, be unfavorable for realizing automatic grinding because artificial proportion is higher in the assembling and dissembling process.
The summary of the invention the purpose of this utility model is to provide a kind of and is installed quick and precisely, the good quick jig of axiality of production efficiency height, workpiece and jig.The utility model mainly includes: cutting ferrule, card body, three claws, three straight pins, three big stage clips and three small pressure springs.Wherein blocking body has a cylindrical shape pillar, and the internal diameter of its end that can link to each other with the grinder main shaft is less than the internal diameter of other parts, pass this little internal diameter screw thread be connected in the grinder main shaft screw corresponding with it.Be fixed with on the outer peripheral face of an adjacent side with grinder (be pillar below) pillar that with its axis normal three are identical approximately to be fan-shaped supporting plate, their exterior arc surface is on same periphery.These three supporting plate sides are plane and two adjacent parallel sided, and spacing equates.Be provided with two open slots on the arc surface of supporting plate, a face of this open slot and supporting plate parallel sided is provided with the pin hole that runs through both.Be fixed with concordant with its end top on the last outer peripheral face of above-mentioned pillar and identically with corresponding three of following supporting plate approximately be fan-shaped card body seat, the exterior arc surface of their exterior arc surface and supporting plate is on same periphery.These three card body seat sides are plane and two adjacent parallel sided, and spacing equates.Arc surface middle part at card body seat is provided with the rectangular aperture groove, and bottom land is the outer peripheral face of pillar.The lower end places the big stage clip top on the supporting plate to be positioned at above-mentioned rectangular aperture groove.Preferably this open slot and big stage clip are in contact with one another the position and establish the cambered surface corresponding with it and be used for installing stage clip, have circular groove to be used for laying stage clip on the supporting plate of lower end.Be provided with the projection of auxiliary work-piece location in addition at card body seat top, its inner ring surface is all in same periphery.Be provided with claw in the gap between adjacent supporting plate of above-mentioned card body and card body seat, this claw main body is width is higher than the pillar top less than card body seat rectangular aperture groove depth, top less than gap, length between the supporting plate a cube.The outer facade top of this claw is outward-dipping inclined-plane, and facade is provided with perpendicular open slot in this claw, is provided with small pressure spring in the groove.Be provided with slotted eye in the claw bottom, this slotted eye is corresponding with the supporting plate pin hole, establishes pin in both holes.Be provided with in the outside of above-mentioned card body and claw and be placed in them in it and the top is stuck in cylindrical shape cutting ferrule on the claw inclined-plane, the periphery of this cutting ferrule is provided with and block corresponding three screws of three rectangular aperture grooves of body seat, is provided with the other end in this screw and is positioned at screw on the big stage clip.
The utility model mainly is to utilize the spring force of the relative motion of claw inclined-plane and cutting ferrule and big small pressure spring to be installed and discharge workpiece.The utility model is when holding workpiece, and the elastic force of big stage clip is pressed in cutting ferrule on the inclined-plane of claw, and the horizontal component of generation makes the claw clamping work pieces, and the while small pressure spring also is impaction state can outwards open claw around the straight pin rotation on the card body.But because the elastic force of big stage clip is much larger than the elastic force of small pressure spring, so following three the uniform claws of nature clamping work pieces under the thrust of cutting ferrule.When external force overcame big stage clip elastic force cutting ferrule is moved down, cutting ferrule no longer was subjected to spring force to compress the claw inclined-plane, and claw outwards opens the release workpiece under the effect of small pressure spring.
The utility model compared with prior art has following advantage:
1, be installed fast, make things convenient for, simple to operate, human factor is few, the production efficiency height.
2, workpiece can guarantee the axiality between itself and jig substantially when being installed, and is installed accurately the machining accuracy height.
3, jig is light small and exquisite, dismounting adjustment easily.
