Description

Device that small-size special snap ring of gold utensil was assembled that absorbs Technical Field The invention relates to the technical field of snap ring assembly special for small-sized absorbing hardware fittings, in particular to a device for assembling the snap ring special for the small-sized absorbing hardware fittings. Background In the field of automated production, the process of taking out the molded product is accomplished by relying on the clamp plate assembly. The suction fitting on the clamp plate is matched with the suction disc, so that a molded product in the die can be taken out, and separation of the product and the die is realized. And then cutting the product and the water gap by using pneumatic scissors to complete an automatic pick-up process. In order to solve the problem that the product falls due to the operation vibration of the manipulator, the tail end of the sucker of the clamp plate is usually provided with a suction fitting, so that the stability of the workpiece taking is improved. The component is widely applied in automation equipment, particularly in a small die scene within 100t, the application requirement of a small-sized absorbing fitting is particularly urgent due to the limited die opening space, the popularization of the component can obviously improve the production efficiency, and the frequency of manual intervention is reduced. The current snap ring assembly mode of the small-sized absorbing hardware fitting has a plurality of defects, and the industrialization level is uneven.
