Adjustable-type nail feeding device in stud welding machine

Abstract

The invention discloses an adjustable-type nail feeding device in a stud welding machine. The adjustable-type nail feeding device comprises a nail feeding shell. A nail feeding channel is formed in the nail feeding shell. The side wall of the nail feeding shell is further provided with a nail stopping air cylinder and a nail falling air cylinder from top to bottom. A spraying-blowing opening is further formed in the position, below the nail falling air cylinder, of the nail feeding shell. An annular proximity switch is further arranged at the position, between the spraying-blowing opening andthe nail feeding channel, of the nail feeding shell. The nail feeding shell is formed by stacking of an upper module, a middle module and a lower module. Locking rods sequentially penetrate through the upper module, the middle module and the lower module from top to bottom, and after pair-lock nuts are tightly screwed correspondingly at the two ends of the locking rods, the upper module, the middle module and the lower module can be stacked and tightly locked to form the nail feeding shell. The upper module is provided with a nail feeding channel inlet and the nail stopping air cylinder, and the lower module is provided with the nail falling air cylinder, the spraying-blowing opening, the annular proximity switch and a nail feeding channel outlet. The adjustable-type nail feeding device can be applied to conveying of studs with different heights and different diameters by replacing the middle modules with different heights and wear-proof sleeves with different inner diameters.

Description

technical field [0001] The invention relates to the field of welding equipment, in particular to an adjustable nail feeding device in a stud welding machine. Background technique [0002] The stud welding machine is a kind of welding equipment that can weld studs quickly. There is a vibrating plate in the stud welding machine. The device transports the studs one by one into the welding gun for stud welding. The structure of the conventional nail feeding device includes: a nail feeding shell, a nail feeding channel is arranged on the nail feeding shell, the entrance of the nail feeding channel and a vibrating plate After the output end of the machine is docked, the studs conveyed by the vibrating plate can enter the nail feeding channel against each other end to end. There is also a nail stop cylinder and a nail dropping cylinder on the side wall of the nail feeding housing from top to bottom. After the piston rod of the nail cylinder is stretched out, it can pass through th...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned nail feeding device can only transport studs of a specific height, because the described nail feeding device cannot adjust the distance between the nail stop cylinder and the nail dropping cylinder according to the height of the stud, and the distance between the stud height and the nail stop cylinder, the nail dropping cylinder When the distance between the nail cylinders does not match, the nail stop cylinder will not be able to stand on the second stud from bottom to top supported by the piston rod of the nail drop cylinder, so the nail feeding device will not work properly
