Rotatable pneumatic gripping tool

Abstract

The invention relates to a rotatable pneumatic gripping tool, which comprises a rotary head, a thimble, a cylinder body, a piston, a cylinder cover shaft, a shaft sleeve assembly and an air supply source, wherein three clamping jaws are connected to the rotary head; the tail parts of the clamping jaws extend into the rotary head; the tail parts of the clamping jaws are provided with small holes; the clamping jaws are connected through the small holes on the tail parts by using a circular tension spring; the front end of the thimble extends into the rotary head; the front end of the thimble has a conical shape which is matched with the tail contact surface of each clamping jaw; the thimble is connected with the piston through a screw; the piston is arranged in the cylinder body; a spring is arranged between the inner front end face of the cylinder body and the piston; the front end of the cylinder body is in threaded connection with the rotary head; the back end of the cylinder body is connected with one end of the cylinder cover shaft; the other end of the cylinder cover shaft passes through a ventilation disk in a shaft sleeve seat, and is locked through a shaft coupling; the shaft sleeve seat is provided with a ventilation hole; and the air supply source is communicated with the ventilation disk. Synchronous clamping of the three clamping jaws is realized through one-way air supply, 360-degree revolving during air supply is realized through a coaxial air path, clamping of the three clamping jaws and the revolving action do not influence each other, and the overall dimensions of the three clamping jaws are small.

Description

technical field [0001] The invention relates to a grabbing tool, in particular to a rotatable pneumatic grabbing tool. Background technique [0002] The assembly of various workpieces in industrial production is mostly carried out on the assembly line, such as the processing and assembly industry of auto parts, home appliance industry, etc. During the assembly process, the workpiece needs to be picked up and moved a certain distance to make it reach the corresponding position. Most of the lighter cylindrical workpieces are manually operated, but the efficiency of manual operation is low, the working time is long, and it is not suitable for continuous production in large quantities. At present, there is no special grabbing tool for picking up such small workpieces. The general grabbing tool has a large volume, and the gripping action of the jaws is not flexible, and it cannot rotate 360°, which is inconvenient to operate.

Problems solved by technology

For cylindrical workpieces with light weight, manual operation is mostly used, but the efficiency of manual operation is low, the working time is long, and it is not suitable for continuous production in large quantities.

At present, there is no special grabbing tool for picking up such small workpieces. The general grabbing tool is large in size, the gripping action of the jaws is not flexible, and it cannot rotate 360°, which is inconvenient to operate.
