Description

Background
The fixture is an indispensable auxiliary device in the machining and manufacturing processes and mainly plays a role in positioning and clamping. Under the action of external force, in order to keep the workpiece at a predetermined position without displacement and ensure the processing quality and production safety, the workpiece must be firmly fixed by a clamping device.
Generally, the clamping device mainly comprises a force source device, an intermediate force transmission mechanism and a clamping element, and is classified according to the source of the clamping force, and generally comprises the following parts: manual clamping, motorized clamping and automatic clamping; the clamping mechanism is classified according to the complex and simple conditions of the clamping mechanism and can be divided into a simple clamping mechanism and a composite clamping mechanism; the clamping mechanism can clamp the workpieces at one time according to the number of the workpieces which can be clamped by the clamping mechanism at one time, and can be divided into single-piece clamping, double-piece clamping and multi-piece clamping; in addition, the clamping mechanism is divided into self-locking and non-self-locking.
At present, the clamping mechanism which is applied more is the traditional thread type clamping mechanism, has the advantages of large clamping force, good self-locking property, simple operation, convenient manufacture, long service life and the like, and is widely applied to various fields, such as G-shaped clamps, bench vices and the like. The traditional clamping device forces the clamp teeth to approach the center of the workpiece by means of the advancing and retreating of the threads, and the workpiece is clamped by means of the action of the clamp teeth, so that the clamping device can adapt to the large diameter change range to a certain extent and clamp the workpiece; however, with the action of the external force on the workpiece in the machining process, the cutting force borne by the workpiece is rapidly increased, so that the workpiece vibrates or moves, the accurate positioning of the workpiece is affected, and the machining error of the workpiece is caused. The above-mentioned influence is reflected especially obviously in the cylindrical fuze clamping process, because the periphery of the fuze needs to be clamped when the fuze is clamped, in order to prevent the fuze from rotating, a larger clamping force needs to be provided, so that the fuze has the risk of being clamped and deformed or damaged, and the clamping mode can not fully ensure that the fuze does not displace in the processing and assembling processes. In addition, the existing clamping mechanism is often fixed on an indoor workbench, the work of the clamping mechanism is often limited by the field, and certain application limitation exists.
