Steel wire preloading crimping device

Abstract

The invention discloses a steel wire preloading crimping device, and belongs to the technical field of medical instrument auxiliary devices. The steel wire preloading crimping device comprises a mounting plate and a plurality of preloading assemblies mounted on the mounting plate, each preloading assembly is used for preloading a steel wire and comprises a first loading air cylinder, a second loading air cylinder, a wire clamp structure and a first guide rail, the wire clamp structure is slidably connected to the first guide rail, the first guide rail is arranged on the mounting plate, and the wire clamp structure is used for clamping the steel wire; and a first telescopic rod of the first loading air cylinder is in sliding connection with the wire clamp structure, a limiting piece on the first telescopic rod is matched with the first telescopic rod to drive the wire clamp structure to slide in the preset direction and tension the steel wire, and a second telescopic rod of the second loading air cylinder is fixedly connected with the wire clamp structure and drives the wire clamp structure to slide along the first guide rail, wherein the first loading air cylinder is used for driving the wire clamp structure to calibrate the primary tension of the steel wire, and the second loading air cylinder is used for driving the wire clamp structure to calibrate the secondary tension of the steel wire.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a steel wire preload crimping device. Background technique [0002] The soft tissue robot is equipped with a multi-functional channeler. The adjustable vertebral component of the multi-functional channeler uses steel wires to achieve up, down, left and right bending movements. In order to ensure that each steel wire achieves the same action effect under the same force, It is necessary to ensure that the length of the steel wire is consistent and the preload is consistent. Therefore, a certain force should be loaded on the steel wire when the steel wire is crimped, and at the same time, it is necessary to ensure that the loaded force is equal in magnitude. [0003] In the prior art, various forms of vertebral segments are used to form an adjustable vertebral assembly, and then steel wires are used for traction or the steel wires of the vertebral segments are us...
