Description

Technical Field

[0001] This utility model belongs to the field of gasket assembly technology, specifically relating to a metal gasket gripper. Background Technology

[0002] Automation technology is becoming increasingly widespread in modern industrial production, especially in the assembly field. To improve efficiency and accuracy, every step on an automated assembly line must be meticulously designed to ensure smooth processes and product safety. In ammunition assembly lines, primer assembly is a crucial step. The correctness of primer gasket assembly directly affects the quality of the final product.

[0003] Under current technology, primer gasket assembly is still done manually. Because the gasket is extremely thin, even slight external force can deform it. The inner diameter of the gasket is similar to the diameter of the primer, so manual operation requires extra care when installing the gasket into the primer to prevent deformation. Although manual assembly is flexible, it is difficult to guarantee the efficiency and consistency of quality. Utility Model Content

A transmission belt is fitted onto the main pulley and the driven pulley.

[0008] Preferably, a pulley adjusting sleeve is fitted onto the upper end of the rotating shaft, and the driven pulley is fitted and fixed onto the pulley adjusting sleeve.

[0009] Preferably, the telescopic pin assembly has three or more circumferentially spaced around the axis of rotation.

[0010] Preferably, the negative pressure suction plate has an air supply hole in the middle for connecting to the negative pressure air hole, and a connector for connecting to an air source is installed on the air supply hole. The connector is located on the upper side of the negative pressure suction plate and spaced apart on the lower side of the floating connecting plate.

The flexible contact is achieved by the telescopic pin assembly, which provides cushioning and prevents the gasket from deforming. This facilitates the improvement of assembly efficiency and quality consistency, and is especially suitable for ring gaskets.

[0017] 2. The negative pressure vents are arranged in a ring shape to ensure uniform negative pressure distribution and stable adsorption force, thereby improving the reliability and stability of the gasket gripping and ensuring assembly accuracy.
