Abstract
The utility model relates to a sleeve grinding clamp, which consists of a mandrel. A conical mandrel body is arranged at one end of the mandrel and a clamping cone and a handling nut are arranged at the other end of the mandrel in a sleeved way; the handling nut is connected with the mandrel by a screw pair; the clamping cone is arranged between the conical mandrel body and the handling nut, and a short-diameter end of the clamping cone is opposite to the short-diameter end of the conical mandrel body. A circular hole is arranged on the end surface of a long-diameter end of the clamping cone and an annular groove is arranged on the internal wall of the circular hole; two radial grooves are arranged on the annular groove. Two bumps are arranged on the external circumference of one end of the handling nut and the two bumps are both arranged in the annular groove. The workpiece can be fixed by placing the workpiece to be machined between the clamping cone and the conical mandrel body, and hiring the handling nut to place stress on the clamping cone. The bump at one end of the handling nut is arranged in the annular groove in the internal wall of the end surface hole of the clamping cone; when the workpiece is unloaded, the handling nut can pull the clamping cone out of the workpiece. The sleeve grinding clamp can ensure the coaxiality between the internal hole and an external circle of the workpiece.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to the machine cut servicing unit, particularly a kind of sleeve clamp.
Background technology:
Sleeve part all needs to carry out to foreign round grinding usually, and needs to guarantee the axiality of cylindrical and endoporus, because the clamping difficulty is difficult to the Geometrical Tolerance Principle that proposes in the assurance design.In the prior art, usually the axle with anchor clamps is designed to cylindrical, but its cylindrical of cylindrical mandrel and part endoporus certainly exist the gap, this gap directly causes the coaxiality error of endoporus and cylindrical after the part processing, therefore to improve machining accuracy, just must reduce this gap, and the too little loading and unloading difficulty that causes in gap; Also there is technology that axle is designed to taper shape, though conical axle has an end and workpiece very close to each other, but there is the gap in the other end, this gap still influences the coaxial accuracy after the part processing, improve machining accuracy, just must reduce the tapering of axle, can cause axle oversize like this, not only cost improves, and uses inconvenient.
Summary of the invention:
The purpose of this utility model provides a kind of sleeve clamp, and the grinding fixture that described this sleeve clamp will solve prior art middle sleeve class part can not guarantee the technical problem of the axiality of endoporus and cylindrical effectively.
This sleeve clamp of the present utility model is made of axle, wherein, one end of described axle is provided with the conical mandrel body, be arranged with one on the other end of axle and clamp cone and a loading and unloading nut, described loading and unloading nut is connected with axle by screw thread pair, described clamping cone body is positioned between conical mandrel body and the loading and unloading nut, and the minor axis end of clamping cone and the minor axis end of conical mandrel body are in opposite directions.
Further, be provided with circular hole in the end face of the major diameter end of described clamping cone, be provided with cannelure in the inwall of described circular hole, described cannelure is provided with two radial slots, one end excircle of described loading and unloading nut is provided with two projections, and described two projections all are positioned at cannelure.
The tapering that further clamps cone equates with the tapering of described conical mandrel body.
Operation principle of the present utility model is: workpiece to be processed is placed between clamping cone and the conical mandrel body, utilizes the loading and unloading nut clamping the cone pressurization, and can fixation workpiece.The projection of loading and unloading nut one end is arranged in the cannelure that clamps cone end-face hole inwall, and when unloading workpiece, the loading and unloading nut can be pulled out in workpiece clamping cone.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model promotes to clamp cone by the loading and unloading nut in the sheathed clamping cone of the other end of conical mandrel, can realize the clamping to the cylinder barrel shaped workpiece, has guaranteed the axiality of workpiece endoporus and cylindrical.
Description of drawings:
Fig. 1 is the structural representation of sleeve clamp of the present utility model.
Fig. 2 is the left view of sleeve clamp of the present utility model.
The specific embodiment:
As depicted in figs. 1 and 2, sleeve clamp of the present utility model is made of axle 1, described axle 1 one ends are provided with conical mandrel body 2, wherein, be provided with clamping cone 3 and loading and unloading nut 4 at described axle 1 other end, the tapering of described clamping cone 3 equates that with the tapering of described conical mandrel body 2 small end of described conical mandrel body 2 and described clamping cone 3 is towards described axle 1 middle part, and described loading and unloading nut 4 is arranged at described axle 1 other end by screw thread pair.
Further, large-diameter end in described clamping cone 3 is provided with porose, be provided with cannelure 31 in the inwall in hole, two radial slots 32 are set on described cannelure 31, described loading and unloading nut 4 is provided with two projections 41 near described clamping cone 3 one distolateral walls, and described two projections 41 are positioned on same the diameter line.
Further, described projection 41 is along the thickness of the axial thickness of described loading and unloading nut 4 less than described cannelure 31.
Concrete, add man-hour, rotate loading and unloading nut 4, promote to clamp cone 3 by loading and unloading nut 4 front end face A workpiece 5 is clamped; Backward rotation loading and unloading nut 4 unclamps workpiece 5 by the rear end face B that loads and unloads nut 4 convex platforms 41, and the conical surface that clamps cone 3 and axle body 2 passes through loading and unloading nut 4 with workpiece 5 location and clamping, and guarantees the axiality of endoporus and cylindrical.
