Problems solved by technology

Among them, the first one is the most common and cheap, but it is cumbersome and time-consuming to set up the clamping, and the accuracy is not high
The second method is slightly better than the first one, and the accuracy and time are in the middle of the three, but it cannot be used on machine tools such as wire cutting
The fixture of the third clamping method is expensive and has high precision, but it cannot be used on machine tools such as wire cutting

Abstract

The invention provides a universal clamp applicable to clamping plastic molds on various processing units. The universal clamp comprises a bas and a clamping device. The base comprises a foundation bed, a grooved electromagnetic chuck, a pneumatic device and the like, quick positioning between the base and the clamping device is realized via the pneumatic device, and a workpiece to be machined is supported and fixed by the grooved electromagnetic chuck. The clamping device comprises a push plate, a screw, a support piece, bar-shaped pieces and the like, and the push plate can be translated via the screw so as to lock an end face of the workpiece to be machined. The universal clamp is mainly applicable to continuous machining and measuring processes of mold parts of a numerically controlled machining center, an electric spark machine tool, a line cutting machine tool, a tri-linear coordinates measuring instrument and the like, and automatic continuous production of mold manufacturing in a mold manufacturing automatic production line can be realized by an industrial manipulator or a robot.

Description

technical field [0001] The invention relates to the field of machining fixtures, in particular to a universal fixture suitable for clamping plastic molds on various processing equipment. Background technique [0002] The core and cavity of plastic molds generally need to be processed or inspected by CNC machining centers, electric discharge machine tools, wire cutting machine tools, three-coordinate measuring instruments and other equipment during the processing process. For different types of equipment, different mold fixtures are required In order to realize the processing link between the various processing equipment. At present, most domestic mold companies still use traditional fixtures such as yardsticks. Every time the processing equipment is replaced, it needs to be leveled and centered. This not only has poor precision but also takes time, making it difficult to realize automation and informatization in mold processing. Therefore, a universal fixture suitable for i...
