Problems solved by technology

[0003] However, in the current tightening equipment for the valve body and spool, the bolts of the workpiece are usually tightened by hand-held tightening guns. Not only is the work efficiency low and the labor intensity is high, but also prone to missing tightening of the bolts, and the value of the bolt tightening torque cannot be controlled. The problem that the quality cannot be guaranteed

Abstract

The invention relates to the technical field of mechanical equipment, in particular to an anti-pinch automatic tightening machine. The anti-pinch automatic tightening machine comprises a machine frame; the machine frame is provided with at least one set of automatic tightening mechanisms and a set of anti-pinch clamps for clamping workpieces; the automatic tightening mechanisms tighten the workpieces in the anti-pinch clamps; each anti-pinch clamp comprises a fixed clamp and a sliding clamp slidably arranged on one side of the fixed clamp; a cavity for holding the workpieces is formed betweeneach sliding clamp and the corresponding fixed clamp; limiting strips for limiting the positions of the workpieces are arranged in the cavities; the workpieces fall from the cavities when the slidingclamps slide down; and by designing the anti-pinch clamps, operators can be effectively prevented from being pinched in the workpiece placing process, and after the workpieces are machined, the sliding clamps slide down, so that the qualified workpieces are automatically dropped and centralized.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to an anti-pinch automatic tightening machine. Background technique [0002] The tightening machine is a kind of electric wrench tool. The tightening machine can automatically control the size of the torque. During the assembly process of the workpiece, it can not only improve the work efficiency, but also play a role in preventing mistakes in the sequence of bolt tightening and preventing mistakes in bolts. Ensure that the pressing force of the product is accurate during the tightening assembly without breaking and deforming due to excessive torque. [0003] However, in the current tightening equipment for the valve body and spool, the bolts of the workpiece are usually tightened by hand-held tightening guns. Not only is the work efficiency low and the labor intensity is high, but also prone to missing tightening of the bolts, and the value of the bolt tightening torqu...
