The utility model content
The utility model provides a kind of specific position bolt, gear type bolted instruments that efficient simple in structure, easy to use is high such as fastening turning or dead angle that can be used in order to overcome bolted instrument of the prior art easily and the workpiece peripheral structure interferes and can't fastening turning or the deficiency of the bolt of the specific position such as dead angle.
To achieve these goals, the utility model adopts following technical scheme:
a kind of gear type bolted instrument, comprise housing, described housing comprises upper cover body and the base that is connected with upper cover body, be provided with cavity between described upper cover body and base, be provided with gear train in described cavity, described gear train comprises driving wheel and driven pulley, described driving wheel is provided with power shaft, power shaft one end and base are rotationally connected, the other end passes upper cover body and forms input, described driven pulley is provided with output shaft, described output shaft one end and upper cover body are rotationally connected, the other end passes base and forms output, the input of described power shaft is provided with the spanner joint, the output of described output shaft is provided with muff joint.Muff joint connects corresponding sleeve, whole instrument is stretched into need fastening bolt place, jacket casing is entered on bolt, the spanner joint of input coordinates with pneumatic impact spanner, but open just fastening bolt of pneumatic impact spanner, the power shaft of this kind instrument and output shaft be not on same straight line, and the muff joint of output shaft end can be stretched into some turnings and dead angle place, the bolt that can facilitate fastening turning rapidly or dead angle to locate.
As preferably, be provided with drive between described driving wheel and driven pulley, described drive is provided with power transmission shaft, and an end and the upper cover body of described power transmission shaft are rotationally connected, and the other end and base are rotationally connected.Between driving wheel and driven pulley, drive is installed, is so just made turning to of output shaft consistent with turning to of output shaft, be convenient to judgement and operation.
As preferably, the diameter of described driving wheel is greater than the diameter of drive and driven pulley.Pneumatic impact spanner drives driving wheel and rotates, and the rotating speed of driven pulley is greater than the rotating speed of driving wheel, so the efficient of fastening bolt is high.
As preferably, the junction of described power shaft, power transmission shaft and output shaft and upper cover body and base all is provided with bearing.Bearing is all installed at the place of connecing of power shaft, power transmission shaft and output shaft and upper cover body and base, can effectively reduce like this resistance that gear rotates.
As preferably, the side of described upper cover body is provided with oil filler point.Gear train all needs oiling to reduce the frictional resistance of gear engagement place at set intervals, improves the stability that gear rotates, and therefore has oil filler point in the engagement place of the side of upper cover body corresponding gear.
Therefore, the utlity model has the bolt of specific positions such as can be used for fastening turning or dead angle, the high beneficial effect of efficient simple in structure, easy to use.
