Retractable clamping jaw with changeable pitch

Abstract

The invention relates to a retractable clamping jaw with the changeable pitch. A Z-axis mechanism of the clamping jaw can adjust the vertical position of the whole device. A pitch adjusting motor transmits the power to a synchronous wheel b through a synchronous wheel a and a synchronous belt, the synchronous wheel b drives a lead screw b, the lead screw b rotates to drive a lead screw a to rotate, the distance between a first connecting plate and a fourth connecting plate can be adjusted through two reverse nuts, the distance between a second connecting plate and a third connecting plate can be driven by a connecting rod to be adjusted equally, and therefore the horizontal distance of each set of connecting plates can be adjusted within a certain range. A pneumatic finger drives two clamping jaw heads, the unfolding or folding of the finger can drive the two clamping jaw heads to move together, and therefore the function of placing and taking products can be achieved. The distance between the two clamping jaw heads can be manually adjusted. Each set of vertical lifting air cylinders can be independently operated to drive the clamping jaw connecting plates to ascend or descend and to enable each set of clamping jaw heads to be independently lifted. The clamping jaw can clamp different types of products with the size within a certain range, the distance between clamping jaws can be adjusted, and production efficiency is high.

Description

Technical field: [0001] The invention relates to the field of clamping jaw equipment, and more specifically relates to a clamping jaw whose horizontal distance can be freely changed within a certain range and which can be independently extended and contracted in the vertical direction. Background technique: [0002] Gripper devices in the prior art are generally only equipped with one set of grippers, which can only grip a set of products, and the grippers need the cooperation of other mechanisms to change positions in the three-axis direction, and the grippers do not have a detection function. Whether the product is clamped can not be determined, and the clamping jaws of the prior art can no longer adapt to the clamping work of multi-station and more complicated processes, and need to be improved. Invention content: [0003] The object of the present invention is to address the shortcomings of the prior art, to provide a variable-pitch telescopic gripper, which is a gripp...
