Problems solved by technology

[0002] The three-jaw chuck is a machine tool accessory that uses the radial movement of three movable jaws evenly distributed on the chuck body to clamp and position the workpiece. Before processing, the opening of the three-jaw chuck is often much larger than the size of the workpiece to be processed or When the opening of the three-jaw chuck is much smaller than the size of the processed workpiece, the operator usually needs to manually use the three-jaw chuck wrench to shrink or expand the three-jaw chuck, which not only consumes the labor of the operator, but also reduces the work efficiency.

Abstract

The invention discloses a quick expansion and quick contraction auxiliary clamping device. The device comprises a lathe body, wherein a cutting cavity provided with a forward opening is formed in thelathe body, a three-jaw chuck cavity is arranged at the left side of the cutting cavity in a communicating mode, a wide tooth cavity is arranged at the upper side of the cutting cavity, a clamping block moving cavity extending upwards is arranged at the upper side of the wide tooth cavity, a clamping block limiting cavity is arranged at the upper side of the clamping block moving cavity in a communicating mode, a clamping block cavity is arranged at the upper side of the clamping block limiting cavity in a communicating mode, and a speed-changing cavity is arranged at the left side of the widetooth cavity. According to the device, a motor big gear drives a driven shaft to rotate through a driven small gear, finally high-speed rotation of a clamping shaft with low torque is realized, therefore, quick clamping is realized, and machining efficiency is improved; after clamping jaws make contact with a workpiece, gear shifting is performed through a torque detector, a motor small gear drives the driven shaft to rotate through a driven big gear after gear shifting, finally low-speed rotation of the clamping shaft with high torque is realized, and therefore low-speed clamping is realized; and during clamping, a fan works to clean cuttings, so that the locating precision of clamping is improved.

Description

technical field [0001] The invention relates to the technical field related to lathes, in particular to a quick expansion and quick contraction auxiliary clamping device. Background technique [0002] The three-jaw chuck is a machine tool accessory that uses the radial movement of three movable jaws evenly distributed on the chuck body to clamp and position the workpiece. Before processing, the opening of the three-jaw chuck is often much larger than the size of the workpiece to be processed or When the opening of the three-jaw chuck is much smaller than the size of the processed workpiece, the operator usually needs to manually use the three-jaw chuck wrench to shrink or expand the three-jaw chuck, which not only consumes the labor of the operator, but also reduces the work efficiency. Contents of the invention [0003] In view of the deficiencies of the above-mentioned technologies, the present invention proposes a quick-expanding and fast-retracting auxiliary clamping d...
