Problems solved by technology

[0003] In the manufacturing factory, if the products are connected by rivet nuts, there will be a large number of rivet nut operations. Manual hand-held rivet nut guns are used to operate, which has low operating efficiency and poor product consistency; the other is to use a three-dimensional mobile device to control the rivet nuts. The automatic rivet nut device of the gun, but the current automatic rivet nut device is not highly automated, and the assembly efficiency and quality are still not high, which needs further improvement
In addition, the current automatic rivet nut device using a three-dimensional moving device can only deal with straight workpieces, and cannot deal with curved workpieces
[0004] like image 3 As shown, the automobile luggage rack workpiece 31 is a square tubular metal piece with a curved arc, and the rivet nuts need to be riveted on the multiple round holes 31B arranged on the pipe wall 31A with a curved arc, and the manual hand-held rivet nut gun is used for operation. Not only the working efficiency is low, but also the consistency of the product cannot be guaranteed due to the existence of the curved arc of the pipe wall 31A; the current automatic rivet nut device using a three-dimensional moving device is obviously not competent

Abstract

The invention provides an automatic nut riveting device and an automobile luggage carrier workpiece tube wall round hole nut riveting method. The device comprises a pneumatic nut riveting gun (20), a two-dimensional moving device, a rotating device and a second cylinder (21), the pneumatic nut riveting gun vertically and bilaterally moves by the aid of the two-dimensional moving device and rotates by the aid of the rotating device, the second cylinder (21) pushes a switch piece (20A) of the pneumatic nut riveting gun, a vibrating disk device capable of automatically supplying riveting nuts (24) is arranged beside the second cylinder, a first workpiece shelf (32) for placing a single automobile luggage carrier workpiece (31) is arranged in front of the second cylinder and can bilaterally move, the pneumatic nut riveting gun (20) sucking the riveting nuts (24) rotates along with a rotating plate (11) before the riveting nuts (24) are pulled, and the axis of an opening of the pneumatic nut riveting gun is consistent with that of a round hole (31B). The device is high in automation degree and nut riveting operation efficiency, fine in product consistency and particularly suitable for automatic nut riveting operation of the automobile luggage carrier workpiece with a bending radian.

Description

technical field [0001] The invention relates to an automatic riveting nut device and a method for riveting nuts in round holes of tube walls of automobile luggage rack workpieces. Background technique [0002] Such as figure 1 As shown, the rivet nut 24 is a standard connector commonly used in engineering. Such as figure 2 As shown, the pneumatic rivet nut gun 20 is a special tool for rivet nuts, and a standard screw 20B of corresponding specifications can be loaded into the gun muzzle. There is an elastic part in the gun muzzle and drives the main shaft to rotate, and the rivet nut 24 is set on the outside of the screw 20B and pushed upward. There will be an elastic feeling when moving, and the main shaft will rotate to screw the screw 20B into the lower threaded hole of the rivet nut 24, and push the switch piece 20A, and the pneumatic rivet nut gun 20 will pull the rivet nut 24 to make it compress and deform, and continue to push Its switch piece 20A, its main shaft c...
