captive screw is a commonly used pressure riveting part. Usually the captive screws are directly riveted on the motherboard, so as to play the role of fixing the components, and there is a high requirement for the distance between the opening holes on the component. Once the distance between the through holes on the component and the If the distances between the riveting holes on the motherboard do not match, the components cannot be riveted on the motherboard, which will result in defective or scrapped products, thereby increasing production costs and reducing production efficiency.
In the riveting connection of various structural parts, waterproof lantern rivets have been widely used in riveting environments that require waterproofing. After the riveting parts are riveted, the waterproof structure area of the mandrel and the waterproof structure of the rivet body There is no complete close fit between the areas. In some riveting ranges, the waterproof performance of the rivet is affected. The main reason is that the traditional processing technology of the mandrel and the materials used bring many troubles to the riveting process. is a problem to be solved at present.
The tie rod and joint of the high-voltage isolating switch are often connected by driving an elastic cylindrical pin into the connecting pin hole. The traditional assembly method is to prevent the tie rod and joint from the V-block, and hold the elastic cylindrical pin to align the connecting pin hole. Then hit it with a hammer. Since the elastic cylindrical pin is small, it is easy to injure people's hands by adopting this assembly method, and at the same time, the elastic cylindrical pin is not positioned accurately, which causes large assembly errors and low assembly efficiency.
