Multifunctional complex curved surface flexible clamping device for external field treatment

Abstract

The invention discloses a multifunctional complex curved surface flexible clamping device for external field treatment. A first clamping unit and a second clamping unit which have the completely samestructure and are symmetrically arranged are included, and the first clamping unit / the second clamping unit comprises a motion control assembly, a flexible clamping assembly and a clamping force adjusting assembly; the motion control assembly comprises a motor, a transmission mechanism and a movable ejector rod which are connected in sequence, and the motor drives the movable ejector rod to do thetelescopic motion through the transmission mechanism; the flexible clamping assembly comprises clamping blocks connected with the tail end of the movable ejector rod and a plurality of fasteners, thetwo ends of a curved surface test sample are placed in the two clamping blocks respectively, and the fasteners are installed on the clamping blocks and fix the upper surface and the lower surface ofthe curved surface test sample; and the clamping force adjusting assembly comprises a hydraulic system, and the clamping force of the fasteners to a curved surface part is adjusted through the hydraulic system. The complex curved surface clamping device is simple in structure, capable of being suitable for samples of various curved surface forms, high in practicability and worthy of popularization.

Description

technical field [0001] The invention belongs to the technical field of flexible clamps, and in particular relates to a multi-functional complex curved surface flexible clamping device for external field treatment. Background technique [0002] The external field treatment technology of materials is to place metal materials in external physical fields such as electric fields, magnetic fields, and ultrasonic fields. After a period of time, the internal microstructure, microstructure and residual stress of the material will be changed, thereby improving the performance of the material. Methods. The implementation of this technology is not affected by factors such as the type, shape, and size of the material, so the parts to be processed have diverse characteristics. Tremors will occur during the processing of magnetic fields and ultrasonic fields, which will affect the correct position of the parts during processing. This puts forward strict requirements for the clamping of pa...
