Bench vice mechanism

Abstract

The invention discloses a bench vice mechanism. The bench vice mechanism solves the problem of workpiece clamping. The bench vice mechanism comprises a vice body, a fixed vice block, a movable vice block, a floating assembly, a rotating plate, a rotating block, a push rod and a push head. Through cooperation between the rotating plate and the floating assembly and dual action of abutting of the push head and the movable vice block, the stability of the clamped workpiece is guaranteed, and the clamping precision and clamping firmness are guaranteed; besides, the bench vice mechanism can lock the clamped piece and effectively prevent the clamped workpiece from shaking and guarantees that demands of follow-up operation can be met; and the whole process is easy to operate, the structure is precise, and the clamping operation can be completed at a high standard.

Description

technical field [0001] The invention relates to the field of fixtures, and more specifically, relates to a multifunctional bench vise mechanism. Background technique [0002] Fixtures have a very important impact on the accuracy and efficiency of various processed and manufactured products. Bench vise is a commonly used clamping device no matter in the field of mechanical processing or other fields, and it is also an indispensable processing tool in the operation of specimens in medical orthopedics. [0003] For the application of vise in the production of human specimens, the second edition of "Anatomy Technique" edited by Li Zhonghua and Wang Xinghai has introduced the chapter on bone sawing. Some bone blocks are often sawn. Commonly used tools are fitter steel silver, carpentry saw, steel wire silver, circular saw blade or craniotomy. It is better to have a narrow sawing path, less damage to the bone, and a smooth silver cut. Fixed bone specimens should be equipped wi...

Problems solved by technology

For example, when making a pelvic midsagittal section specimen, fix both sides of the soft tissue of the hip bone with vise, and then perform technical operations after the specimen is clamped and fixed. The error of the applied force is relatively large, and it is easy to touch the weak part of the bone piece and even damage the entire specimen. Moreover, when sawing the bony part in the follow-up, the vise needs to be tightened. The operation makes the specimen swing excessively, which leads to the deviation of the cutting plane, and also affects the exposure of the anatomical structure, which is not clear and incomplete.

[0005] Although there are currently some devices that can clamp bone-like workpieces, the control accuracy of these devices is relatively lacking, the clamping stability cannot meet the requirements, the general performance is poor, the control system is complicated, and the cost is too high
