Open ratchet two-purpose wrench groove milling clamp

Abstract

The invention discloses an open ratchet two-purpose wrench groove milling clamp, which can perform clamping and fixing conveniently. The clamp comprises a bottom plate, wherein a frame is arranged on the bottom plate; a fixed jaw is reserved on the frame; a groove matched with the handle of an open ratchet two-purpose wrench is formed on the jaw; a sliding block is arranged on one side of the groove; the sliding block is connected with one end of an adjusting screw arranged on the frame; an adjusting hand wheel is arranged on the other end of the adjusting screw; a pressing block matched withthe groove is arranged above the groove; the pressing block is arranged on a movable jaw connected with the piston of a hydraulic cylinder arranged on the upper end of the frame fixedly; a lower bracket is fixedly arranged on one side of the frame; the adjusting screw is arranged on the lower bracket through an adjusting nut; and the end part of the adjusting screw is pressed against an open wrench head on one end of the handle of the open ratchet two-purpose wrench.

Description

technical field [0001] The invention relates to a clamping device, in particular to a special clamp for groove milling of an open ratchet dual-purpose wrench. Background technique [0002] The structure of the open-ended ratchet dual-purpose wrench mainly includes: a handle, an open-ended wrench arranged at one end of the handle, and a ratchet wrench arranged at the other end of the handle. A connecting groove is arranged on the other end of the handle, and the ratchet wrench is fixedly arranged in the connecting groove by a pin. In the process of processing the connecting groove of the ratchet wrench, the workpiece to be processed needs to be fixed on the workbench first. The clamping method currently used is mostly manual clamping, that is, the workpiece is fixed on the workbench with tools such as pressure plates and bolts, which is very inconvenient to operate, and in the process of milling the groove of the ratchet wrench, it is necessary to perform multiple operations...

AI Technical Summary

Problems solved by technology

The clamping method currently used is mostly manual clamping, that is, the workpiece is fixed on the workbench with tools such as pressure plates and bolts, which is very inconvenient to operate, and in the process of milling the groove of the ratchet wrench, it is necessary to perform multiple operations on the workpiece. One-time clamping, in the process of multiple clamping, because the position of the workpiece is different each time, the tool must be re-set after each clamping, the operation is cumbersome, the processing efficiency is low, and the machining accuracy of the parts is affected by human factors Large impact, poor precision stability
