The traditional synchronizer for precision parts processing and assembly equipment has more parts to the centerline to ensure that when the arc is picked up from the conveyor belt, it can be in a well-known place. However, in some applications, forcing parts to align with the centerline may damage parts and equipment. When the part is very small and some collision may cause scratch, when its position is fixed by the machine tool spindle or lead screw, or the tolerance is very small, it is better to make the clamp match the position of the part rather than reverse. For these tasks, Guangdong machining plant Elyria has created a GPN asynchronous series, which is compatible with clamping. Because the force and clamp synchronization system is independent, the synchronization system can be taken by a precise anti-skid system without affecting the clamping force. Clip sizes range from 51B clamping force and 0.2 inch stroke to 40Gb clamping force and 6 inch stroke. Clip products are characterized by smaller and smaller batch size and more diversified products. As the last step of production, assembly is easy to change in batch size and product design. In the past, under such circumstances, many enterprises were forced to put more energy into extensive rationalization and automatic assembly. Although in the context of flexible processing systems such as industrial robots, the development of elastic fixture is rapidly declining, it is possible to try to increase the elastic fixture.
The fact that precision parts processing fixture is a necessary product investment has intensified the necessity of making the fixture more flexible in economy. Fixture can be divided into single fixture, modular fixture, modular fixture and high flexible fixture according to their flexibility. The characteristics of flexible fixture are high adaptability to different workpieces, less transformation time and lower price.
In the production task, the workpiece of Guangdong machining factory is fixed in the fixture, and there are several necessary steps to fix a workpiece. The first step is to determine the position of the workpiece on the fixture, considering the unprocessed surface and working characteristics. After that, the fixed face must be selected. The workpiece is fixed on the fixed surface in the determined position, and the necessary force and torque are added to ensure the necessary working characteristics. Finally, the necessary adjustment position or combination fixture factors should be considered, adjustment or assembly, so that the workpiece is firmly fixed on the fixture. Precision parts processing through such a program, process and process card, fixture assembly can be automatically carried out. The task of structural modeling is to produce the combination of several stable planes, so that the clamping forces on these planes will make the workpiece and fixture stable. By convention, this task can be accomplished by human-computer conversation, which is almost completely automated. The advantages of man-machine dialogue, that is, to determine the fixture structure modeling in an automatic way, are that the fixture design can be organized and planned, the number of designers required can be reduced, the research period can be shortened, and the working conditions can be better configured. In short, it can achieve significant improvement of fixture production efficiency and economic benefits
