Abstract
The utility model relates to a clamping driving plate for a shaft with threads at two ends. The utility model is characterized in that the clamping driving plate comprises a nut-shaped plate body, a movable pressing key, a compression screw and a suspender screw, an axial key slot is arranged on the inner wall of the plate body, the movable pressing key is matched by clearance with the radial direction of the key slot, threads consistent with the inner wall of the plate body are arranged on the internal surface of the movable pressing key, the threaded through hole of the compression screw is arranged on the plate body corresponding to the center of the movable pressing key, symmetrical step-shaped blind holes communicated with the movable pressing key are respectively arranged on the plate body on the two sides of the threaded through hole, the suspender screw is arranged in the blind holes after the suspender screw is sheathed in a compression spring, the lower end of the suspender screw is screwed and fixed in the threaded hole of the movable pressing key, and a driving lever is connected with the other side of the plate body symmetrical with the compression screw. When in use, the shaft end of a workpiece is screwed in the nut of the plate body and the workpiece can be processed after the compression screw is screwed in to tightly lock the nut and the workpiece. After processing, the compression screw is loosened and the workpiece is taken out. The utility model has the advantages that the workpiece is firmly and reliably clamped during the processing and the threads at the end of the workpiece are not damaged.
Description
Technical field
The utility model relates to a kind of clamping tool for machine work, the clamping dial of the screwed axle in particularly a kind of two ends.
Background technology
At present, the screwed axle in two ends is being processed, when keeping in repair, generally is being to adopt pressing plate or heart carrier clamping work pieces that cause the workpiece threaded portion to damage easily, clamping workpiece is not firm.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned weak point, and provides a kind of solid and reliable to clamping workpiece, not the clamping dial of the screwed axle in the two ends of defective work piece end screw thread.
In order to realize the foregoing invention purpose; the technical solution adopted in the utility model is: the clamping dial of the screwed axle in a kind of two ends; the disk body that comprises nut type; the movable key of pressing; housing screw; the hang spring screw rod; have an axial keyway on the disk body inwall; the movable key of pressing places in the keyway; both radially between matched in clearance; guarantee that the movable key of pressing can radially slide in keyway; the movable key inner face of pressing has and the corresponding to screw thread of disk body inwall; have tapped through hole on the disk body at corresponding movable pressure key center; housing screw screws in the tapped through hole; on the disk body of tapped through hole both sides, have the straight-through movable blind hole of pressing in the key of symmetry; blind hole is that the outer end is big; inner little step-shaped hole; there is screw thread the inner; the hang spring screw rod is inserted in the compression spring and is placed in the blind hole, by fixing in the movable screwed hole of pressing in key of its lower end screw-in, and is connected with driving lever on the disk body another side of housing screw symmetry.
The utility model, screws in the workpiece axle head in the nut of disk body during use owing to adopt above design, and precession housing screw drive activity presses key to press to workpiece, will can carry out workpiece processing after nut and the workpiece locking.After machining, unclamp housing screw, the movable key original position of being sling back under the compression spring action on the hang spring screw rod of pressing can be taken out workpiece.Solid and reliable in the process to clamping workpiece, defective work piece end screw thread not.
