Quick-changing type jaw vice

Abstract

The invention belongs to a tool clamp, and in particular to relates a quick-changing type jaw vice. The quick-changing type jaw vice comprises sliding chute seats, a support plate and a base, wherein the support plate is arranged on the base; a positioning plate is arranged on the lower part of the support plate; the left sliding chute seat and the right sliding chute seat are arranged on the support plate; movable vice openings are respectively formed in the left sliding chute seat and the right sliding chute seat; a spring is arranged in a space which is formed by the movable vice openings and the sliding chute seats; a backing block is arranged on one clamping side of the movable vice openings; locking screws are also arranged on the sliding chute seats; short pins are arranged on the locking screws; a lever is arranged on the support plate; a handle is arranged at one end of the lever; a short arm is arranged at the other end of the lever; and a sliding pin penetrates through the short arm and is connected with the left movable vice openings and the right movable openings. By the quick-changing type jaw vice, the handle of the lever is pressed downwards or loosened, so that a workpiece can be rapidly released and clamped again.

Description

technical field [0001] The invention relates to a tooling fixture, more specifically to a quick-change vise, which belongs to the technical field of mechanical manufacturing. Background technique [0002] Existing bench vices or table vises rely on the screw pair to drive the movable jaws to open or close relative to the fixed jaws to loosen or clamp the workpiece. Since the pitch of the transmission screw is relatively small, it is difficult to loosen or clamp the workpiece. The number of rotations of the workpiece screw is large, the clamping or releasing of the workpiece is not fast enough, and in the process of clamping the workpiece, in order to prevent the workpiece from loosening, a relatively large torque must be applied to the screw rod, which is not convenient during use. [0003] In view of the current status quo, there is an urgent need for a vise that is relatively labor-saving and can be very convenient to clamp and release the workpiece, so as to realize the q...
