Grabbing gripper for three-way valve bodies

Abstract

The invention relates to a grabbing gripper for three-way valve bodies. The grabbing gripper comprises a box body base and a main driving wheel. The main driving wheel is provided with wheel teeth and pin teeth, the wheel teeth are meshed with a rack, and the rack is connected with an air cylinder. Three gear sets are arranged below the main driving wheel and each comprises an outer ring gear and an inner ring gear, each outer ring gear is connected with a first rotating shaft, each inner ring gear is connected with a second rotating shaft, each first rotating shaft is connected with a first rotary connection gear, each second rotating shaft is connected with a second rotary connection gear, each first rotary connection gear is meshed with a first rack, each second rotary connection gear is meshed with a second rack, the first racks and the second racks are fixedly connected to first hinge bases, a second sliding groove is formed between every two first sliding grooves, second hinge bases are installed in the second sliding grooves, planar four-link mechanisms are connected between the second hinge bases and the first hinge bases, and clamping blocks are installed at the lower ends of the second hinge bases. According to the grabbing gripper, the three pairs of clamping blocks can be automatically controlled to slide in opposite directions, and therefore the three-way valve bodies can be clamped in multiple directions.

Description

technical field [0001] The invention relates to a mechanical device for processing a valve body, in particular to an extraction gripper for a three-way valve body. Background technique [0002] Generally speaking, in the process of highly automated processing of the three-way valve body, due to the heavy weight of the valve body itself, robots are often used for handling. However, due to the large volume of the three-way valve body, before handling, it is necessary to The three-way valve body needs to be clamped and grasped in at least three positions, but in actual operation, conventional robot grippers often have complex structures and control methods, and are inconvenient to operate. Contents of the invention [0003] Aiming at the defects of the traditional robot gripper, the present invention proposes an extraction gripper for a three-way valve body which is easy to control and has a higher degree of automation.
