Embodiment Construction

[0014] like Figure 1-2 As shown, a floating bolt tightening device described in the embodiment of the present invention mainly includes two sets of identical transmission rods, two sets of identical floating devices, and mounting seats 3. The rod system is respectively installed on one pair of corners of the mounting base 3, and two sets of floating devices are respectively installed on the other opposite corner of the mounting base 3. Each transmission rod system mainly includes a transmission rod 1, a compression spring 2 and a socket wrench 5, The socket wrench 5 is fixed on the top of the transmission rod 1, and the bottom end of the transmission rod 1 is provided with a hexagonal column head 4. The transmission rod 1 is inserted on the mounting seat 3 and can slide up and down along the mounting seat 3. The compression spring 2 is sleeved on the transmission rod 1 The upper two ends rest between the socket wrench 5 and the mounting seat 3. Each set of floating devices ma...

Abstract

The invention discloses a floating bolt tightening device, which mainly includes two sets of identical transmission rods, two sets of identical floating devices and mounting seats. On one pair of corners of the mounting seat, two sets of floating devices are respectively installed on the other opposite corner of the mounting seat. Including short shaft, upper thrust bearing, lower thrust bearing and nut. The present invention is provided with a floating device on the mounting seat, which can effectively solve the problem that the bolt tightening failure is easily caused due to the non-adjustable position of the transmission rod, and greatly improves the first-time success rate of bolt tightening.

Description

technical field [0001] The invention relates to the field of automobile assembly equipment, in particular to a floating bolt tightening device. Background technique [0002] In the automobile assembly process, bolt tightening is one of the important processes. When the car is assembled, most of the car parts are pre-assembled on the pallet first, and then re-assembled. During pre-installation, the tightening of the bolts on the auto parts is done by the operator using the transmission rod on the pallet to align the bolts. However, generally the position of the transmission rod in the horizontal direction is fixed, and when the transmission rod is out of axis with the corresponding bolt due to assembly or manufacturing errors, it will lead to tightening failure. Therefore, if the horizontal position of the transmission rod can be adjusted, the first-time success rate of bolt tightening will be greatly improved. Contents of the invention [0003] In order to solve the abo...
