Abstract

The embodiment of the invention provides a device and a method based on magnetic field force for realizing peg-in-hole assembly. The device comprises a shell and a rotary sleeve arranged outside the shell in a sleeving mode. When jamming occurs between an assembly shaft and an assembly hole, the driving effect of the magnetic field force to the assembly shaft can be used for realizing peg-in-hole assembly, the problems that the assembly work fails because of low position control precision and uncontrollable contact force in the position control mode and assembled work-pieces are even damaged can be avoided, the assembly problem of the work-pieces with rough assembly hole walls or with high assembly precision requirements is solved, the magnetic field force is adopted in the assembly work, the shortcomings of traditional position control in high-quality and high-accuracy assembly work are overcome, and the assembly quality and the work efficiency are greatly improved.

Description

Technical field: [0001] The invention relates to the application field of industrial robots, in particular to a device for realizing shaft hole assembly based on magnetic field force and a method for using the device to realize shaft hole assembly. Background technique: [0002] At present, in the field of machinery, industrial robots are mainly used to assemble shaft holes, most of which are aimed at the smoothness of the assembly hole wall. When assembling workpieces with rough assembly hole walls or high assembly precision requirements, the assembly task can only be completed manually. , work efficiency is low. [0003] The patent with publication number CN102218652B discloses a device and method for using the compliance of the robot to realize shaft hole assembly, but it relies on position control to realize shaft hole assembly, and cannot control the contact force. For rough assembly hole walls or assembly When a workpiece with high precision requirements is assembled,...
