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.

Technical field
The present invention relates to automobile and attach together equipment field, be specifically related to a kind of fastener for bolt.
Background technology
In Automobile Assembling Technology, bolt tightening is one of important technique.During automobile assembling, auto parts are first pre-installed mostly on supporting plate, and then secondary assembling.During prepackage, the tightening of bolt on auto parts, it is urgent to be that operator utilizes the drive link on supporting plate to aim at bolt.But the position of general drive link horizontal direction is fixing, when drive link is due to assembling or the reason of foozle and respective bolt disalignment, will cause tightening unsuccessfully.So the horizontal level of drive link is adjustable will greatly improve the one-time success rate of bolt tightening if can make.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of fastener for bolt, this apparatus structure is simple, easy to operate, solves the problem easily causing bolt tightening failure because drive link position cannot be adjusted.
Object of the present invention carrys out specific implementation by the following technical programs:
A kind of fastener for bolt, mainly comprise one group of transmission leverage, two groups of identical floating installations and mount pad, the cross section of described mount pad is triangular in shape, described transmission leverage is arranged on mount pad wherein on a drift angle, two groups of floating installations are arranged on other two drift angles of mount pad respectively, described drive link owner will comprise drive link, Compress Spring and box spanner, described box spanner is fixed on drive link top, drive link bottom is provided with hexagonal column cap, described drive link is plugged on mount pad and also can slides up and down along mount pad, described Compress Spring is socketed in two ends on drive link and is resisted against between box spanner and mount pad, described floating installation of often organizing mainly comprises minor axis, up-thrust bearing, lower thrust-bearing and nut, described minor axis is plugged on mount pad, the top that described nut is positioned at minor axis is threaded with minor axis, up-thrust bearing, lower thrust-bearing is all set on minor axis, up-thrust bearing is between mount pad and nut, lower thrust-bearing is between mount pad and minor axis termination, minor axis diameter is less than the internal diameter of up-thrust bearing and lower thrust-bearing.
Further, between described drive link and mount pad, sliding sleeve is installed.
Further, described box spanner is connected with drive link by resilient key.
Further, pad is provided with between described up-thrust bearing and nut.
A kind of fastener for bolt of the present invention, is provided with floating installation, solves the problem easily causing bolt tightening failure because drive link position cannot be adjusted, greatly improve the one-time success rate of bolt tightening between drive link and supporting plate.
