Description
Technical field
The utility model relates to automobile and attaches together equipment field, is specifically related to a kind of bolt tightening servicing unit.
Background technology
In Automobile Assembling Technology, bolt tightening is one of important technique, and traditional Bolt Screw Down Method mainly contains high-precision rifle automatic tightening and manually hand-heldly tightens two kinds.High-precision rifle automatic tightening, automaticity is high but flexibility is poor, compare, manually hand-held adaptability of tightening is stronger, but it is large that shortcoming is labor strength, and especially when running into small space, tightening tool is difficult to enter, and acquire a certain degree of difficulty by manually coming to aim at bolt in time, valuable work tempo will be consumed like this.So if a kind of servicing unit can be had to help raising manually tighten efficiency, reducing labor intensity, is very necessary.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of bolt tightening servicing unit, and this assistant apparatus structure is simple, easy to operate, solves and causes manually tightening inefficient problem because of narrow space.
The purpose of this utility model carrys out specific implementation by the following technical programs:
A kind of bolt tightening servicing unit, mainly comprise power shaft, output shaft, transmission device, box spanner and fixed mount, described power shaft is parallel with output shaft to be staggeredly arranged, power shaft is connected by transmission device with output shaft, power shaft is all flexibly connected with fixed mount by rolling bearing with output shaft, described box spanner is fixed on output shaft top, and described power shaft bottom is provided with hexagonal column cap.
Further, described transmission device mainly comprises input belt wheel, cog belt and output pulley, and described input belt wheel is connected with input axle key, and described output pulley is connected with output axle key.
Further, described fixed mount mainly comprises upper plate, contiguous block and lower plate, and described contiguous block is arranged in the middle of upper plate and lower plate, and is fixedly connected with lower plate with upper plate.
Further, described box spanner is connected with output shaft by resilient key.
A kind of bolt tightening servicing unit of the utility model, power shaft is parallel with output shaft to be staggeredly arranged and to be in transmission connection by cog belt, the position of manually tightening is shifted out from small space is parallel, has both solved the problem cannot placing spanner, turn improve manually tighten convenience, flexibility.

Detailed description of the invention
As shown in Figure 1-2, a kind of bolt tightening servicing unit described in the utility model embodiment, mainly comprise power shaft 1, output shaft 2, transmission device, box spanner 5 and fixed mount, power shaft 1 is parallel with output shaft 2 to be staggeredly arranged, power shaft 1 is connected by transmission device with output shaft 2, power shaft 1 is all flexibly connected with fixed mount by rolling bearing 9 with output shaft 2, and box spanner 5 is fixed on output shaft 2 top, and power shaft 1 bottom is provided with hexagonal column cap 10.
Further, transmission device mainly comprises input belt wheel 3, cog belt 11 and output pulley 4, and input belt wheel 3 is connected with power shaft 1 key, and output pulley 4 is connected with output shaft 2 key.
Preferred embodiment, fixed mount mainly comprises upper plate 6, contiguous block 8 and lower plate 7 to one, and contiguous block 8 is arranged in the middle of upper plate 6 and lower plate 7, and is fixedly connected with lower plate 7 with upper plate 6.Box spanner 5 is connected with output shaft 2 by resilient key 12.
During use, the utility model is fixed on the supporting plate of automobile chassis, due to the relative positioning relation of supporting plate and bodywork parts, output shaft 2 is aimed at treating above supporting plate all the time and is tighted a bolt, when tightening, operator is hand-held tightens the hexagonal column cap 10 that power shaft 1 bottom aimed at by rifle, presses and tightens rifle switch, power passes to output shaft 2 from power shaft 1, and the box spanner 5 on output shaft 2 just starts urgent bolt.
Last it is noted that the foregoing is only preferred embodiment of the present utility model; be not limited to the utility model; for a person skilled in the art; it still can regulate the technical scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
