Bench vice with five degrees of freedom

Abstract

The invention discloses a bench vice with five degrees of freedom. The bench vice comprises a bench vice body, a movable vice stand, a vice body lead screw and a rocking handle. The lower portion of the bench vice body is of a circular arc-shaped structure, the lower portion of the bench vice body is matched with a rotating disc with a circular arc-shaped clamping groove, the bottom of the rotating disc is matched with a rotating base in a rotating mode, and a pressing block and a fixing bolt used for fixing the bench vice body are arranged on the rotating disc. The rotating base is fixed on a vice stand base plate. An X-axis moving mechanism which is mainly composed of first guide rails, a first guide rail sliding block and a first lead screw and a Y-axis moving mechanism which is mainly composed of second guide rails, a second guide rail sliding block and a second lead screw are arranged below the vice stand base plate. The X-axis moving mechanism and the Y-axis moving mechanism are perpendicularly arranged, the vice stand base plate is in linkage fit with the first guide rail sliding block, and the X-axis moving mechanism is in linkage fit with the second guide rail sliding block. A lifting mechanism which is mainly composed of scissor jacks is arranged below the Y-axis moving mechanism. The bench vice with five degrees of freedom has the advantages of being simple in structure and high in machining efficiency.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a five-degree-of-freedom bench vise. Background technique [0002] For decades, driven by the development of CNC machine tools in the direction of high speed, high efficiency, precision, compound, intelligence and environmental protection, the corresponding fixture technology is developing in the direction of high precision, high efficiency, module, combination, general purpose and economy. Fixtures are one of the indispensable parts of mechanical processing; in mechanical processing, bench vise is a very common clamping tool. It uses two jaws as positioning reference, and the principle of transmitting mechanical force by screw and nut for work. Bench vise is divided into machine use and manual use. The structure of the bench vise is simple, and the clamping is fast; the processing process saves time and effort, which not only improves work efficiency and processin...

AI Technical Summary

Problems solved by technology

The main function of the ordinary bench vise is to clamp the workpiece. During the processing, it can only complete the fixing function and only have one degree of freedom; when processing multiple surfaces of the workpiece, it is very inconvenient. After processing one surface, It is necessary to remove the workpiece from the bench vise, change the angle of the workpiece and then clamp it to the bench vise

In actual production, mold processing is not limited to single-sided workpiece processing, but for parts with complex shapes, it is completed through four-axis or five-axis CNC machining centers, and CNC machining centers have a large investment in equipment. High processing requirements

The machine tool equipment in the machining center is dangerous. For example, during the drilling process, the bench vise is often not fixed at the lower end of the bed. If the cutting force is large, the bench vise will rotate with the rotation of the part. Cause processing difficulties or even cause personal injury or death
