Expansion sleeve clamping device

Abstract

The invention relates to an expansion sleeve clamping device. The expansion sleeve clamping device comprises a pedestal, a shifting fork, inner hexagon screws, a cylindrical pin with an internal thread, a clamp bottom plate, a stop pin, a pressing plate, a cover plate, a rotating handle, a push rod, clamp plates, an external cone-shaped expansion sleeve, an internal supporting expansion sleeve, a cushion block, a supporting vertical plate and a fixed support. The pressing plate is pressed by rotating the rotating handle, so that the tail end of the pressing plate is in contact with the stop pin; by taking the fixed support as a pivot, according to the lever principle, the shifting fork will push the push rod to move upward in the perpendicular direction and push the internal supporting expansion sleeve to move upward, so that circular conical surfaces of the external cone-shaped expansion sleeve and the internal supporting expansion sleeve are matched, and the excircle of a workpiece is clamped. The clamping device provided by the invention has the beneficial effects that the workpiece is quickly clamped and loosened and detached by skillfully utilizing the lever principle, the device is simple and feasible, the production efficiency of an enterprise is improved, and the production and manufacturing costs are lowered.

Description

technical field [0001] The invention belongs to the field of mechanical processing and manufacturing, and in particular relates to an expansion sleeve clamping device.
