Quick-action multipurpose bench clamp

Abstract

The invention discloses a quick-action multipurpose bench clamp which comprises a movable clamp body, a screw rod, a fixed clamp body, a support, an end cover and a quick-action device. The screw rod meshed with a nut is arranged on the movable clamp body; a handle in the quick-action device is of a bent shape; the turned position in the middle of the quick-action device is matched with a rotating shaft arranged on a convex lug; the other end of the quick-action device is in running fit with the nut penetrating through a fin; a torsion spring sleeves the rotating shaft; a nut handle sleeved with a spring and the nut are of an integrated structure; the nut and the nut handle are arranged in the radial direction and are vertical to the screw rod arranged in the axial direction; when the fin is pressed and the handle is pulled out, the nut and the screw rod can be separated in a screw thread manner; when the handle is loosened, the nut and the screw rod can be meshed in a screw thread manner under the action of the spring and the torsion spring. The quick-action multipurpose bench clamp has all functions of a common multipurpose bench clamp, and an additional function of quick movement of the movable clamp body and a quick-action function of rapidly pushing the movable clamp body when the screw rod and the nut are meshed in a screw thread manner, is flexible to operate and convenient, has high working efficiency and is low in labor intensity.

Description

Technical field [0001] The invention relates to the technical field of fitter clamping tools, in particular to a quick-action multi-purpose vise. Background technique [0002] Multi-purpose vise is a rotary multi-purpose clamping tool for fitter, mainly used for clamping and fixing work pieces of different shapes during fitter's processing. [0003] The existing common multi-purpose vise includes a movable pliers body, a fixed pliers body, a support, a chassis, a shift rod, a screw rod, a nut and an end cap. The specific structure is: a screw rod is installed on the movable pliers body, and the screw rod A shift lever is installed at one end of the caliper; the movable pliers body is installed on the fixed pliers body, and the fixed pliers body is installed on the support and fixedly connected with the end cover; the support is installed on the chassis. A nut which is an integral structure is arranged at the center of the end cover, and the nut is engaged with the screw rod. The ...

AI Technical Summary

Problems solved by technology

[0004] Without a quick-action device, the nut and screw thread cannot be separated, so the fast movement of the movable pliers cannot be realized, and the movable pliers cannot be quickly pushed toward the fixed pliers.

[0005] When the screw nut is engaged with the thread of the screw rod, turning the lever and the screw rod can only drive the movable pliers to move slowly; for workpieces with large size differences and frequent replacement, it is necessary to rotate the screw rod frequently and for a long time. The relative displacement between the movable pliers and the fixed pliers will make the heavy work of the fitter more clumsy, increase the labor intensity of the fitter, and reduce the work efficiency.
