Abstract
The utility model discloses a cylindrical gear clamp which comprises a mandrel provided with a positioning end plate. The cylindrical gear clamp is characterized in that the mandrel is sleeved with a taper-lock and a pressing plate in a sliding mode, the inner wall and the outer wall of the taper-lock are provided with annular grooves distributed in a crossed mode, the mandrel is provided with a gland nut through threads, the positioning end plate, the taper-lock, the pressing plate and the gland nut are sequentially and axially distributed, and a pressing sleeve is arranged on the outer side of the gland nut. The cylindrical gear clamp has the advantages that clamping is firm, workpieces are not prone to rotation, and machining quality is improved.
Description
Technical field
The utility model relates to a kind of fixture for roller gear, carries out the fixture of Shaving Process especially for roller gear.
Background technology
Existing roller gear is when carrying out Shaving Process, and the fixture using comprises that mandrel, the slip with locating end plate is loaded on the pressing plate on mandrel mostly, and its adopts the mode that both ends of the surface are compressed to complete the clamping to workpiece; But the fixture of this structure, the fastness of its clamping is poor, and workpiece easily rotates, and crudy is difficult to guarantee.
Utility model content
The purpose of this utility model is for prior art above shortcomings, and a kind of roller gear fixture is provided, and it has advantages of, and clamping is firm, workpiece is difficult for rotating, and can improve crudy.
For achieving the above object, a kind of roller gear fixture of the present utility model, comprise the mandrel that is provided with locating end plate, it is characterized in that the cover sliding has expansion set and pressing plate on mandrel, the inside and outside wall of expansion set is provided with the annular groove of cross arrangement, on mandrel, by screw thread, be provided with clamp nut, locating end plate, expansion set, pressing plate, clamp nut are successively in axially-aligned; At clamp nut, be also provided with gland outward.
During use, on the expansion set that workpiece is placed on, and one end is near locating end plate, and rotates clamp nut, promotes pressing plate extruding expansion set, makes expansion set distortion, expands, and by workpiece swelling, gland presses the other end of workpiece simultaneously; The utility model not only compresses workpiece both ends of the surface, and by expansion set, workpiece is carried out to swelling, centering, and clamping is more firm, and workpiece is difficult for rotating, and can improve crudy;
As further improvement of the utility model, pressing plate is provided with axial groove, is provided with anti-turn screw on mandrel, and the head of this screw is positioned at groove; Can avoid the rotation of pressing plate, reduce wearing and tearing;
In sum, the utlity model has the advantage that clamping is firm, workpiece is difficult for rotation, can improve crudy.
Accompanying drawing explanation
Fig. 1 is the front view of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, this roller gear fixture, comprise the mandrel 1 that is provided with locating end plate 2, the cover sliding on mandrel 1 has expansion set 3 and pressing plate 4, and the inside and outside wall of expansion set 3 is provided with annular groove 3a and the 3b of cross arrangement, on mandrel 1, by screw thread, is provided with clamp nut 5, locating end plate 2, expansion set 3, pressing plate 4, clamp nut 5 are successively in axially-aligned, pressing plate 4 is provided with axial groove 4a, is provided with anti-turn screw 7 on mandrel 1, and the head of this screw 7 is positioned at groove 4a; Outside clamp nut 5, be also provided with gland 6.
During use, on the expansion set 3 that workpiece 8 is placed on, and one end is near locating end plate 2, and rotate clamp nut 5, promote pressing plate 4 extruding expansion sets 3, annular groove 3a and 3b can make expansion set 3 distortion, expand, by workpiece 8 swellings, simultaneously by the top other end that makes gland 6 press workpiece 8 on tail stock for machine tool; The utility model not only compresses workpiece both ends of the surface, and carries out swelling, centering by 3 pairs of workpiece of expansion set, and clamping is more firm, and workpiece is difficult for rotating, and can improve crudy.
