Left and right tooth lead screw type automatic centering clamp system

Abstract

The invention discloses a left and right tooth lead screw type automatic centering clamp system, which comprises a seat body and a lead screw, wherein two ends of the lead screw are rotationally connected with two ends of the seat body; left and right clamping arms for clamping a workpiece are arranged on the lead screw; the lead screw is connected with the left and right clamping arms by screw threads; the lead screw is divided into a left lead screw and a right lead screw; the screw threads of the left lead screw and the right lead screw have equal thread pitch and opposite rotating directions; and when the lead screw is rotated in the nonuse rotating direction, two movable chucks generate synchronous relative movement or synchronous opposite movement. The system can be automatically adapted to automatic centering of the workpieces of different sizes, has wide application in automatic production lines, particularly has quite obvious application advantage under the condition that the requirement of the central line is higher than that of the outline, and does not need manual metering for correction and centering; and the system has a simple and reasonable structure, is convenient and quick to operate, and has good application and popularization values.

Description

technical field [0001] The invention relates to a clamping device in the industrial field, in particular to a left and right screw rod type automatic centering clamp system. Background technique [0002] Clamping or vices of current industrial machines, automation equipment, etc. such as figure 1 or figure 2 As shown, its action principle is to fix one of the clamping surfaces, and then pass the screw ( figure 1 ), cylinder or cylinder ( figure 2 ) and so on to push the other clamping surface to move to the fixed clamping surface, so as to achieve the purpose of clamping the workpiece. However, in the actual production process, there is a tolerance M on the outer contour (or clamping surface) of the upper difference workpiece and the lower difference workpiece, such as image 3 As shown, in such a case, if the next process is to process on the centerline of the workpiece (such as drilling, milling, etc.), the outer contour tolerance M of the two workpieces will be brou...
