Abstract

The invention discloses a bolt tightening device. The bolt tightening device mainly comprises a drive rod system, two same floating devices and an installing base. The section of the installing base is triangular. The drive rod system is installed on one vertex angle of the installing base, the two floating devices are installed on the other two vertex angles of the installing base respectively, and the drive rod system mainly comprises a drive rod, a compression spring and a socket spanner. Each floating device mainly comprises a short shaft, an upper thrust bearing, a lower thrust bearing and a nut. The short shafts are inserted into the installing base, and the diameter of the short shafts is smaller than the inner diameter of the upper thrust bearings and the inner diameter of the lower thrust bearings. Because the floating devices are arranged between the drive rod and a supporting plate, the problem that due to the unadjustable position of the drive rod, a bolt fails to be tightened is solved, and the success rate of tightening the bolt at a time is greatly increased.

Description

technical field [0001] The invention relates to the field of automobile assembly equipment, in particular to a 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 above techni...
