Abstract

The embodiment of the invention provides equipment for achieving shaft hole assembly and a method for achieving shaft hole assembly through the equipment. The equipment comprises a support and a power device fixedly arranged on the support. The support is provided with a lead screw capable of being driven by the power device to rotate. The lead screw is sleeved with a lead screw nut capable of vertically moving along the lead screw. A connecting plate is arranged on one side of the lead screw nut. The connecting plate is provided with a smoothening device for achieving shaft hole assembly based on magnetic field force, and a clamping mechanism connected with the smoothening device is arranged below the smoothening device. When the lead screw is driven by the power device to rotate, the lead screw nut can vertically move along the lead screw and meanwhile drives the smoothening device connected with the lead screw nut to move downwards. The jamming problem generated when an assembly hole wall is smooth or coarse is mainly solved, the magnetic field force is integrated in assembly work, the defects of traditional position control in high-quality and high-precision assembly work are overcome, and the assembly quality and working 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 and a method for realizing shaft hole assembly by using the device. Background technique: [0002] In industrial production in the 21st century, under the circumstances of rising labor costs and the transformation and upgrading of traditional manufacturing industries, it is of great significance for enterprises to realize highly automated production of assembly operations. In the assembly operation, the shaft hole assembly is the most basic task in mechanical assembly. The quality of assembly has a great impact on the application process of the product. The processing and assembly of some fine parts relying on the ordinary control system can no longer meet the demand. . For example, in the high-precision shaft hole assembly operation, due to many uncertainties and emergencies in the environment, the assembly operation often...
