Gun head for hand riveter and using method

Abstract

The invention discloses a gun head for a hand riveter and a using method, and belongs to the field of riveting tools. The gun head comprises a body and an adjusting assembly, a through hole for inserting a rivet is formed in the body and penetrates through the body, a counter bore is formed in the first end of the body, the counter bore and the through hole are coaxially arranged, and the other end of the body is used for being connected with the hand riveter; the adjusting assembly comprises a first shaft pipe, a second shaft pipe and a third shaft pipe, a first boss is arranged on the outer wall of the middle of the first shaft pipe and protrudes out of the body, the first end of the first shaft pipe is coaxially and detachably inserted into the counter bore, and the second end of the first shaft pipe is coaxially inserted into the first end of the second shaft pipe; and the first end of the third shaft pipe is coaxially inserted into the second end of the second shaft pipe, and the first shaft pipe and the third shaft pipe are in threaded fit with the second shaft pipe. According to the gun head for the hand riveter, the riveting strength can be guaranteed, and the application range of the gun head can be widened.

Description

technical field [0001] The invention belongs to the field of riveting tools, and more specifically relates to a gun head for a riveting gun and a use method thereof. Background technique [0002] Riveting is a riveting method that uses manual or compressed air as power to deform a special rivet through a riveting gun to rivet the riveted parts. It is a kind of cold riveting. The main materials and tools used in riveting include riveting guns and rivets. [0003] In the related art, in order to increase the strength of the composite material, the alloy material is usually arranged on the upper surface of the composite material, and then the alloy material and the composite material are riveted by riveting with a riveting gun. [0004] However, the surface of the alloy material has an inverted T-shaped hole (to reduce weight and avoid solid drilling). The diameter of the inverted T-shaped hole is small and the length in the vertical direction is different. The installation m...

Problems solved by technology

[0004] However, the surface of the alloy material has an inverted T-shaped hole (to reduce weight and avoid solid drilling). The diameter of the inverted T-shaped hole is small and the length in the vertical direction is different. installed, so that the riveting strength is low (alloy material is easy to be squeezed and deformed), and the riveting cannot be effectively riveted

In addition, it is necessary to open holes in the alloy material or use other processing methods to complete the connection, resulting in a greatly reduced connection efficiency between the alloy material and the composite material
