Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be an intervening element at the same time. When an element is referred to as being "disposed on" another element, it can be directly disposed on the other element or intervening elements may also be present.

[0025] Unless otherwise defined, all technical and scientific terms used here...

Abstract

The invention provides a hand riveter. The hand riveter comprises a gun body and a gun head. The gun body is axially provided with a negative-pressure air chamber and a hydraulic chamber which are incommunication. The gun head is detachably connected with the gun body and comprises a communication chamber communicating with the hydraulic chamber and a gun nozzle fixedly connected with the communication chamber. The side, close to the gun nozzle, in the communication chamber is coaxially provided with a clamping claw chamber. A conical top end is arranged on the clamping claw chamber, and a clamping claw part is formed by the conical top end and used for clamping a blind rivet. An elastic piece and a piston are arranged in the hydraulic chamber, one end of the elastic piece is connected with the negative-pressure air chamber, and the other end is connected with the piston. The clamping claw chamber is driven by the piston to axially move along the communication chamber. Since the automatic hand riveter is provided with the negative-pressure air chamber and the hydraulic chamber at the same time, under cooperation of the negative-pressure air chamber and the hydraulic chamber, automation of different stages such as rivet feeding, rivet pulling and rivet discharging of the hand riveter is achieved. The automatic hand riveter is high in riveting efficiency and speed; and manual blind rivet placement is not needed, rivet arranging and rivet feeding are finished at the same time, and accordingly the production efficiency is improved.

Description

technical field [0001] The invention relates to a riveting gun, in particular to a riveting gun which integrates automatic nail insertion, riveting and nail output. Background technique [0002] Riveting guns are used for fastening and riveting of various metal sheets and pipes, and are currently widely used in steel connections in electromechanical and light industries such as automobiles, aviation, railways, refrigeration, elevators, etc. Developed to solve the shortcomings of metal sheet and thin tube welding nuts are easy to melt, and inner nuts are easy to slip. [0003] In the prior art, during the use of the riveting gun, it is necessary to manually use the vacuum negative pressure to suck the gun nozzle against the nail rod, and then complete the riveting. Manual suction and nailing consumes physical strength, long working hours, low efficiency and low production capacity, and cannot be applied in the field of automation. Contents of the invention [0004] In vie...
