Electric machine vise with dual movable jaws

Abstract

The invention relates to an electric machine vise with dual movable jaws. The electric machine vise comprises a rotary base, a clamping mechanism, an angle adjusting structure and a control box, wherein the clamping mechanism is arranged at one end of the rotary base through a hinge, the angle adjusting structure is arranged at the other end of the rotary base and used for adjusting the angle of the clamping mechanism, and the control box is used for controlling the clamping mechanism and the angle adjusting structure. The clamping mechanism comprises a vise seat and two movable vise bodies, and the two movable vise bodies are slidably arranged on the vise seat symmetrically. Driving lead screws arranged along the long edge of the vise seat are arranged on two sides of the vise seat respectively, threads on two sides of each driving lead screw are opposite in turning direction, a driving motor is connected to one end of each driving lead screw, and the driving lead screws are in threaded connection with two sides of the two movable vise bodies. The electric machine vise with the dual movable jaws has the advantages that a workpiece machining operation range becomes wider through the rotary base and the angle adjusting mechanism, time waste during workpiece clamping is reduced through the dual movable vise bodies, and clamping efficiency and reliability are both improved throughmotor driving.

Description

technical field [0001] The invention relates to an electric double-movable jaw vise, in particular to a clamping, supporting and positioning device for a workpiece or a tool, and at the same time has a rotating or tilting device, in particular to an electric double-moving jaw vise. Background technique [0002] At present, China is a big manufacturing country, and it is moving from a big manufacturing country to a powerful country. Machining is widely used, and flat-nose pliers are generally used to clamp workpieces in machining. Most of the original flat-nose pliers for clamping are manually clamped, which is inconvenient for operators to operate. The workpiece needs to be tightened by hand and flat-nose pliers on one side. The labor intensity is large and difficult to operate, such as a new type of anti-upturning double-jaw flat-nose pliers disclosed in the document of application number CN201720297705.3 or disclosed in the document of CN201220456166.0 Precision machining...

Machining is widely used, and flat-nose pliers are generally used to clamp workpieces in machining. Most of the original flat-nose pliers for clamping are manually clamped, which is inconvenient for operators to operate. The workpiece needs to be tightened by hand and flat-nose pliers on one side. The labor intensity is large and difficult to operate, such as a new type of anti-upturning double-jaw flat-nose pliers disclosed in the document of application number CN201720297705.3 or disclosed in the document of CN201220456166.0 Precision machining of self-centering vise, the above-mentioned scheme improves some problems of the prior art to a certain extent, but this scheme also has at least the following defects, such as the movement of the pliers body still needs to be driven by manpower, while the vise The angle can not be adjusted so that the processing of the workpiece is limited. For example, the universal vise disclosed in the document of application number CN96221597.X, the above-mentioned scheme has improved some problems of the prior art to a certain extent, but There are also at least the following defects. The adjustment of the angle of the vise requires manual operation, which is time-consuming and laborious, and the accuracy of the angle adjustment cannot be accurately controlled. Pliers, the above-mentioned scheme has improved some problems of the prior art to a certain extent, but the scheme also has at least the following defects, such as only one movable tong body, and too much time will be wasted when the workpiece is clamped. A screw used to drive the movable clamp body will cause uneven force on the workpiece clamped on both sides of the clamp body. In summary, the flat-nose pliers cannot accurately perceive the clamping force of the workpiece, and human error may occur. Workpiece damage due to excessive force
