Description
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, it is one of important technique that bolt is tightened.During automobile assembling, auto parts are first pre-installed mostly on supporting plate, the most again secondary assembling.During prepackage, the tightening of bolt on auto parts, is that operator utilizes the drive link alignment bolt on supporting plate urgent.But, the position of general drive link horizontal direction is fixing, when drive link due to assembling or the reason of foozle the most coaxial with respective bolt time, will cause tightening unsuccessfully.So, if can make, the horizontal level of drive link is adjustable will be greatly improved the one-time success rate that bolt is tightened.
Summary of the invention
In order to solve above-mentioned technical problem, the present invention provides a kind of fastener for bolt, and this apparatus structure is simple, easy to operate, solves and is easily caused, because drive link position cannot be adjusted, the problem that failure tightened by bolt.
The purpose of the present invention implements by the following technical programs:
nullA kind of fastener for bolt，Mainly include one group of transmission leverage、Two groups of identical floating installations and mounting seat，The cross section of described mounting seat is triangular in shape，Described transmission leverage is arranged on a mounting seat wherein drift angle，Two groups of floating installations are separately mounted on other two drift angles of mounting seat，Described drive link owner drive link to be included、Compression spring and box spanner，Described box spanner is fixed on drive link top，Drive link bottom is provided with hexagonal stigma，Described drive link is plugged in mounting seat and can slide up and down along mounting seat，Described compression spring is socketed in two ends on drive link and is resisted against between box spanner and mounting seat，Described often group floating installation mainly includes short axle、Up-thrust bearing、Lower thrust-bearing and nut，Described short axle is plugged in mounting seat，Described nut is positioned at the top of short axle and is connected with short male thread，Up-thrust bearing、Lower thrust-bearing is all set on short axle，Up-thrust bearing is between mounting seat and nut，Lower thrust-bearing is between mounting seat and short shaft end head，Minor axis diameter is less than up-thrust bearing and the internal diameter of lower thrust-bearing.
Further, between described drive link and mounting seat, sliding sleeve is installed.
Further, described box spanner is connected with drive link by resilient key.
Further, it is provided with pad between described up-thrust bearing and nut.
One fastener for bolt of the present invention, is provided with floating installation between drive link and supporting plate, solves and is easily caused bolt tightens the problem of failure because drive link position cannot be adjusted, greatly improves the one-time success rate that bolt is tightened.

Detailed description of the invention
nullAs shown in Figure 1-2，A kind of fastener for bolt described in the embodiment of the present invention，Mainly include one group of transmission leverage、Two groups of identical floating installations and mounting seat 3，The cross section of mounting seat 3 is triangular in shape，Transmission leverage is arranged on a mounting seat 3 wherein drift angle，Two groups of floating installations are separately mounted on other two drift angles of mounting seat 3，Drive link owner drive link to be included 1、Compression spring 2 and box spanner 5，Box spanner 5 is fixed on drive link 1 top，Drive link 1 bottom is provided with hexagonal stigma 4，Drive link 1 is plugged in mounting seat 3 and can slide up and down along mounting seat 3，Compression spring 2 is socketed in two ends on drive link 1 and is resisted against between box spanner 5 and mounting seat 3，Often group floating installation mainly includes short axle 8、Up-thrust bearing 9a、Lower thrust-bearing 9b and nut 11，Short axle 8 is plugged in mounting seat 3，Nut 11 is positioned at the top of short axle 8 and threadeds with short axle 8，Up-thrust bearing 9a、Lower thrust-bearing 9b is all set on short axle 8，Up-thrust bearing 9a is between mounting seat 3 and nut 11，Lower thrust-bearing 9b is between mounting seat 3 and short axle 8 termination，Short axle 8 diameter is less than up-thrust bearing 9a and the internal diameter of lower thrust-bearing 9b.
One preferred embodiment, is provided with sliding sleeve 6 between drive link 1 and mounting seat 3, box spanner 5 is connected with drive link 1 by resilient key 7, is provided with pad 10 between up-thrust bearing 9a and nut 11.
During use, the present invention is fixed on the supporting plate of automobile chassis, due to the relative localization relation of supporting plate Yu bodywork parts, near the box spanner 5 on drive link 1 is always positioned at waiting tighting a bolt, when tightening, the hand-held hexagonal stigma 4 tightening rifle alignment drive link 1 bottom of operator, slowly pull floating installation, until box spanner 5 is directed at bolt, presses and tighten rifle switch, power passes to wait to tight a bolt from drive link 1, completes bolt and tightens.
During use, the present invention is fixed on supporting plate, due to the relative localization relation of supporting plate Yu bodywork parts, near the box spanner 5 on drive link 1 is always positioned at waiting tighting a bolt, when tightening, the hand-held hexagonal stigma 4 tightening rifle alignment drive link 1 bottom of operator, slowly pull floating installation, until box spanner 5 is directed at bolt, presses and tighten rifle switch, power passes to wait to tight a bolt from drive link 1, completes bolt and tightens.
Last it is noted that the foregoing is only the preferred embodiments of the present invention; it is not limited to the present invention; for a person skilled in the art; technical scheme described in foregoing embodiments still can be adjusted by it; or wherein portion of techniques feature is carried out equivalent; all within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
