Abstract

The invention relates to a bar clamping mechanism, which includes a clamping part, a housing and a driving part, and is characterized in that: the clamping part includes a transmission gear connected with the driving part, and upper clamps respectively linked with the transmission gear Holding arm, lower clamping arm, left clamping arm, right clamping arm, and four clamping hands respectively installed on the above four clamping arms; Four directions constitute a clamping cavity, and the upper clamping arm, the lower clamping arm, the left clamping arm and the right clamping arm can drive the four clamping hands to approach and move away from the clamping arm as the transmission gear rotates. Movement to maintain the center position of the cavity. The rotation of the motor drives the rotation of the transmission gear, and then drives the movement of the four clamping arms up, down, left, and right, and then drives the four clamping hands to perform the clamping action to achieve the purpose of clamping. This bar clamping mechanism has a simple structure , easy to control, reliable clamping and can clamp rods of different diameters.

Description

technical field [0001] The invention relates to the field of screw forming and manufacturing equipment, in particular to a rod clamping mechanism. Background technique [0002] The screw forming machine is a processing and forming machine for rod-shaped fasteners such as bolts and screws, which involves a bar clamping mechanism, which is mainly used to clamp the bar for shearing, feeding and other processes. At present, the manipulator is usually used as the clamping mechanism on the screw forming machine, which imitates the action of human fingers to clamp the bar. However, the manipulator is often complex in structure, inconvenient to control, and has low clamping reliability. [0003] Therefore, how to design a bar clamping mechanism that can clamp the bar more reasonably and reliably is a problem to be solved urgently by those skilled in the art. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a rod clampin...
