A flexible clamping device for multifunctional and complex curved surfaces used in field treatment

Abstract

The invention discloses a multifunctional and complex curved surface flexible clamping device for external field treatment, which comprises a first clamping unit and a second clamping unit which are identical in structure and arranged symmetrically, the first clamping unit / the second clamping unit The unit includes a motion control component, a flexible clamping component and a clamping force adjustment component. The motion control component includes a motor, a transmission mechanism and a movable ejector connected in sequence. The motor drives the movable ejector through the transmission mechanism to perform telescopic movement; the flexible clamping component includes The clamping block and several fasteners connected to the end of the movable mandrel, the two ends of the curved surface sample are respectively placed in the two clamping blocks, and the fasteners are installed on the clamping block and fixed to the upper and lower surfaces of the curved surface sample. Fixing; the clamping force adjustment assembly includes a hydraulic system, and the clamping force of the fastener on the curved surface part is adjusted through the hydraulic system. The complex curved surface clamping device has a simple structure, can be applied to samples with various curved surface shapes, has strong practicability, and is 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...
