Self-centering floating driving device

Abstract

The invention relates to the technical field of clamps, in particular to a self-centering floating driving device which comprises a chuck body, a tip, a clamping jaw assembly, a main piston, an auxiliary piston, a base, a tailstock and a driving device body. The self-centering floating driving device provided by the invention has a reasonable and compact structure, the driving device drives the main piston to move leftwards, one end of a to-be-machined workpiece is placed to abut against the right end of the tip, the tip achieves a centering effect on the to-be-machined workpiece, and then, the main piston moves rightwards; since each clamping jaw is hinged and connected to the outer side of the chuck body, so that the clamping jaws can float according to the specification of a workpiece to be machined in the clamping process; finally, the workpiece to be machined is clamped under the effect of a reset elastic piece, the clamping position can be automatically adjusted, over-positioning of the clamping jaws is avoided, and high-precision clamping positioning is achieved; and the connecting plate can be prevented from deviating in the process of rotating along with the chuck body through the limiting groove, the stability of the self-centering floating driving device in use is enhanced. The self-centering floating driving device has the advantages of small clamping precision deviation, multi-procedure one-time clamping capability, positioning accuracy, stability and high efficiency.

Description

technical field [0001] The invention relates to the technical field of fixtures, and is a self-centering floating driving device. Background technique [0002] Gripper is one of the important process equipment in the traditional machinery manufacturing industry. After the 1980s, its application has been expanded horizontally to various production fields such as inspection, welding and assembly automation, and it has greater development prospects. [0003] In the production of automatic assembly equipment, jaws are usually used to assist production, such as the positioning of the outer cylinder, spring and gasket of the airtight cylinder. Generally speaking, the outer cylinder, spring and gasket of the airtight cylinder are made of The pallets are transported to the assembly stations on double-speed chains. During assembly, the gaskets and springs on the tray need to be placed in the cylinder of the outer cylinder one by one. Since the springs and gaskets are placed on the t...
