Abstract
The utility model relates to a three-jaw axial tensioning-type tool jig which is provided with a body fixedly connected onto a tool flange. Three radial jaw grooves are evenly formed on an end face of a machining side of the body; the body is sleeved outside an adapter fixedly connected with a machine tool main shaft hydraulic draw bar; a connecting block is fixedly connected onto the adapter, and the connecting block is embedded in the body along an axis of the body; three pulling jaws which are evenly distributed are rotatably connected onto a lateral wall of the connecting block; a location spindle which is coaxial with the body is fixedly connected with the end face of the machining side of the body, three axial clamping grooves corresponding to the pulling jaws are formed on a lateral wall of the location spindle, and the clamping grooves are connected with a long-shaped chute on middle sections of the pulling jaws through pin shafts; a location shaft is arranged on an end face of a machining side of the location spindle, and a rubber washer and a floating location taper are sequentially sleeved on the location shaft; and sliding grooves correspondingly matched with the pulling jaws are formed on lateral walls of both the rubber washer and the floating location taper. The three-jaw axial tensioning-type tool jig is convenient to clamp and stable in clamping, and effectively improves product accuracy.
Description
Technical field
The utility model relates to a kind of jig, a kind of three-jaw axial tightening of special design formula jig.
Background technology
Pawl level product can often be used in actual life, but due to its form and position tolerance axiality, perpendicularity require very high, so must clamped one time Vehicle Processing mesopore, pit, inclined-plane and cylindrical.At present this class part of processing normally adopts the hydraulic pressure scroll chuck, processes take the boss plane of pawl level workpiece as benchmark clamping boss cylindrical.Owing on pawl utmost point boss cylindrical, tapering being arranged, when causing scroll chuck to clamp, pawl utmost point locating surface is uneven, and after processing, gauge is unstable, and perpendicularity can't guarantee, affect product quality.
The utility model content
The purpose of this utility model is to provide a kind of three-jaw axial tightening formula jig for the processing of pawl level clamping workpiece, and this fixture can to pawl level workpiece clamped one time processing mesopore, pit, inclined-plane and cylindrical, guarantee the machining accuracy of workpiece.
The technical scheme that realizes the utility model purpose is: the utlity model has the body that is fixedly connected on the lathe ring flange, evenly offer three pawl grooves radially on the end face of body process side; It is characterized in that: described body is set in the outside of the adapter that is fixedly connected with the machine tool chief axis hydraulic pressure draw-bar; Be fixed with contiguous block on described adapter, contiguous block embeds in body along body axis; Be rotatably connected to three equally distributed pulling claws on the sidewall of described contiguous block, the bottom correspondence of pulling claw is embedded in the pawl groove of body; Be fixedly connected with the apotting spindle coaxial with body on the end face of described body process side, the sidewall of apotting spindle is provided with three axial draw-in grooves corresponding with pulling claw, and draw-in groove links together by the microscler skewed slot of bearing pin and pulling claw interlude; Described apotting spindle process side end face is provided with locating shaft, is arranged with successively rubber washer and floating locator cone body on locating shaft; Be equipped with the chute with the pulling claw corresponding matching on the sidewall of described rubber washer and floating locator cone body.
The sidewall of above-mentioned contiguous block is provided with the axial draw-in groove corresponding with body dewclaw groove, and the draw-in groove on contiguous block links together by the bottom of bearing pin and pulling claw; The center of described contiguous block is provided with fixing hole, and bolt passes fixing hole contiguous block is embedded in body and is fixedly connected on adapter along body axis.
Microscler skewed slot on above-mentioned pulling claw interlude is J-shaped.
Above-mentioned packing ring is elastomeric material.
The utlity model has positive effect: (1) the utility model is simple in structure, is convenient to assembling; (2) the convenient and swift and clamping of the utility model clamping workpiece is stable; (3) the utility model can to pawl level workpiece clamped one time processing mesopore, pit, inclined-plane and outside, when enhancing productivity, can also improve the machining accuracy of workpiece.
