Description
Technical Field
The utility model relates to a chamfering clamp, in particular to a chamfering clamp for a gear with an inner taper hole.
Background
The existing clamp for processing the gear mostly performs gear hobbing, gear shaping or gear milling, and a workpiece bears larger cutting force, so that the requirement on locking force is high, the structure of the clamp is complex, the clamping is inconvenient, and the centering precision of the workpiece is poor due to multiple straight holes in the inner hole, thereby affecting the processing precision.
Disclosure of Invention
The utility model aims to provide a chamfering clamp aiming at the defects in the prior art, and the chamfering clamp has the advantages of simple structure, convenience in clamping and high centering precision and can improve the processing efficiency and precision.
The chamfering clamp comprises a clamp body, a base plate and a pull rod which are connected, and is characterized in that the clamp body is fixedly connected with a shaft sleeve penetrating through the base plate, the outer end of the shaft sleeve is provided with a section of positioning outer cone, the pull rod penetrates through the shaft sleeve and the clamp body in a sliding manner, the pull rod positioned on the outer side of the shaft sleeve is fixedly provided with two shaft shoulders, an elastic expansion sleeve is fixedly provided with a radial convex ring clamped between the two shaft shoulders, the elastic expansion sleeve on the inner side of the radial convex ring is provided with a section of inner cone matched with the positioning outer cone, and the elastic expansion sleeve is provided with an expansion outer cone.
When the elastic expansion sleeve is used, a workpiece is placed on the base plate, the pull rod is pulled down, the positioning outer cone is matched with the inner cone to enable the elastic expansion sleeve to expand, the expansion outer cone is matched with an inner taper hole of the workpiece, the workpiece can be expanded, and the positioning requirement can be met due to the fact that the cutting force of the chamfer is small and the requirement on the locking force is low;
as a further improvement of the utility model, the outer end of the backing plate is provided with an inner taper hole; the method can be suitable for workpieces with more shapes;
in conclusion, the utility model has the advantages of simple structure, convenient clamping and high centering precision, and can improve the processing efficiency and precision.
