RIVETING TRANSMISSION DEVICE AND ELECTRIC RIVETING GUN

摘要

The invention relates to the technical field of riveting transmission, and provides a riveting transmission device. The riveting transmission device includes a bearing rear seat, a bearing front seat and a ball screw rod assembly. The bearing front seat includes a vertical portion, a first horizontal portion and a second horizontal portion. The ball screw rod assembly includes a screw rod assembly, a support member, a screw sleeve gear, a first bearing, and a second bearing. The screw rod assembly is disposed at the first horizontal portion. One end of the support member abuts against the first bearing, and the screw sleeve gear is sleeved at the other end of the support member, and is located outside the bearing rear seat. A first limiting structure is arranged on the bearing rear seat, and a second limiting structure is arranged on the support member. Two ends of the second bearing respectively abut against the first limiting structure and the second limiting structure. The bearing front seat, the bearing rear seat and the ball screw rod assembly are sequentially sleeved, and the overall assembly structure is simple. Moreover, the screw sleeve gear is arranged outside the bearing rear seat, so that the riveting transmission has a shortened overall length, a compact structure, and a smaller occupied space.
