The elastic grinding machine jig has the conical fit and the elastic sleeve structure mounted in the grinding tool equipment jig, and lengthens or shortens the outside diameter of a spring housing through the pressing force of the nut for loosening or clamping the workpiece, thereby effectively avoiding the gap between the jig and the workpiece and reducing the weight of the jig, and the application is convenient.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to frock clamp, particularly a kind of elasticity fixture for grinding machine.
Background technology:
Often need the processing cover parts in the machine-building.The demanding cover parts of dimensional accuracy and roughness, work in-process need just can be finished through grinding.Because the general wall thickness dimension of cover parts is less, the clamping difficulty, and deform easily.In order to guarantee to process the part that adheres to specification, often to manufacture and design a plurality of grindings axle clamp tool diligently.In the prior art, the clamp of cover parts is the cylindrical mandrel frock, owing to inevitably have the gap between cylindrical mandrel and the cover parts, thereby positioning accuracy is lower; Even if adopt the axle of cone shape, though positioning accuracy increases, the axle size is bigger, and consumptive material increases, and weight strengthens, and uses inconvenient.
Summary of the invention:
The purpose of this utility model provides a kind of elasticity fixture for grinding machine, described this elasticity fixture for grinding machine to solve the frock of cover parts in the prior art and workpiece have the gap, frock axle size is big, weight big, use inconvenient technical problem.
This elasticity fixture for grinding machine of the present utility model is made of an axle, wherein, described axle is the multidiameter type, the interlude diameter of axle is greater than the diameter at two ends, be socketed with a resilient sleeve on the excircle of axle interlude, the outer wall of the inwall of described resilient sleeve and axle interlude passes through cone match, the excircle of axle interlude is provided with step, the external diameter of step is greater than the internal diameter of resilient sleeve, the end face of resilient sleeve is outside equipped with a pressing plate, described pressing plate is linked on the axle, the diameter of pressing plate is greater than the internal diameter of resilient sleeve end face, one side of pressing plate is provided with clamp nut, and described clamp nut is connected with axle by screw thread, and the length of resilient sleeve is greater than the projected length of the axle interlude conical surface on axle is axial.
Further, the angle of the described conical surface greater than between described resilient sleeve and the axle from the locking angle.
Further, along the circumferential direction evenly be provided with a plurality of axial gap on described resilient sleeve, the length of any one described gap is all less than the length of resilient sleeve.
Further, the beginning and the closed end of adjacent two described gap are crisscross arranged arbitrarily.
Further, the closed end of any one described gap on resilient sleeve all is circular arc.
Further, described gap quantity is 10.
Further, place, the axle center of described axle two ends end face is provided with center hole respectively.
Operation principle of the present utility model is: sleeve workpiece to be processed is set on the resilient sleeve excircle, driving clamp nut makes axle and resilient sleeve take place axially to relatively move, owing to pass through cone match between axle interlude and the resilient sleeve, so when generation axially relatively moves, the resilient sleeve external diameter becomes big or dwindles, thereby can realize unclamping and clamping of part.The conical surface angle that axle and resilient sleeve cooperate is greater than from the locking angle, the situation of avoiding part to be difficult to unload.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model is arranged at cone match and resilient sleeve structure in the grinding fixture anchor clamps, thrust by nut makes the spring housing external diameter become big or dwindles the clamping that realizes workpiece and loosen, avoid the gap between anchor clamps and the workpiece effectively, alleviated the quality of anchor clamps, easy to use.

The specific embodiment:
As Fig. 1, Fig. 2 and shown in Figure 3, elasticity fixture for grinding machine of the present utility model is made of axle 1, wherein, described 1 axle is the multidiameter of an interlude diameter greater than the two ends diameter, interlude periphery socket in described axle 1 is provided with resilient sleeve 2, cooperate by the conical surface 6 between described resilient sleeve 2 and the described axle 1 interlude outer surface, be provided with not-go-end 5 in described axle 1 interlude one side, the axle 1 that is positioned at described resilient sleeve 2 other ends is provided with clamp nut 3, be provided with pressing plate 4 between described clamp nut 3 and described resilient sleeve 2 other ends, the length of described resilient sleeve 2 is greater than the length of the described axle 1 interlude conical surface 6 along the axle axis direction.
Further, the described conical surface 6 angle [alpha] greater than between described resilient sleeve 2 and the described axle 1 from the locking angle.
Further, along the circumferential direction evenly be provided with a plurality of gap 9 on described resilient sleeve 2, the length of described gap 9 is less than the length of described resilient sleeve 2.
Further, adjacent two described 9 beginnings of gap and closed end are crisscross arranged.
Further, described gap 9 closed end that is arranged in described resilient sleeve 1 body is circular arc.
Further, described gap 9 quantity are 10.
Further, be provided with center hole 7 at described axle 1 two ends.
Tool this, during use, sleeve workpiece 8 is positioned at described resilient sleeve 2 peripheries, is screwed to compress by clamp nut 3 to make resilient sleeve 2 external diameters become big and clamp described workpiece 8; When spin nut 3 outward, resilient sleeve 2 external diameters diminish, and unclamp described workpiece 8.
