CN205325561U - A power spanner for narrow and small space - Google Patents

The utility model discloses a power spanner for narrow and small space, including the power supply, the power supply output is connected with rather than axis vertically power transmission conversion equipment, power transmission conversion equipment includes the casing and sets up the power input that is connected with the power supply output respectively and keep away from the power take off that the power supply is connected with the sleeve and hold on casing both ends, be provided with the gear drive system in the casing. The utility model provides an in narrow and small space, the spanner is unable to get into the operation space and the unable problem that realizes the operation, the operating efficiency of can improving production simultaneously reduces the human cost.

A kind of power operated wrench for small space

Technical field

This utility model relates to machine tool, particularly to a kind of power operated wrench for small space。

Background technology

Power operated wrench is mainly used in Steel Structure Installation industry, installs or removes steel structure high strength bolt specially, the spanner that it is is power with power supply, hydraulic pressure or wind regime, is a kind of instrument for tightening or loosening bolt。It is broadly divided into impact wrench, turns round and cut spanner, constant torque wrench, corner spanner, angular spanner, hydraulic spanner, torque spanner, rechargeable electric wrench etc.。

Currently used spanner is widely applied in mechanical work field, but all there is a common shortcoming in this type of spanner, rotating shaft axial distance longer (power source output shaft shaft length adds length sleeve), at the working space that some are narrow and small, owing to its power transmission rotating shaft axial distance is longer, spanner cannot be introduced into working space and cannot realize operation, and operating personnel has to carry out manual work。

Utility model content

The purpose of this utility model is to overcome deficiency of the prior art, it is provided that a kind of small space (spanner powered by conventional energy cannot be carried out operation) that is applicable to, raising production operation efficiency, reduces the power operated wrench of human cost。

In order to solve above-mentioned technical problem, this utility model provides a kind of power operated wrench for small space, including power source, described power source outfan is connected to the power transmitting and converting device vertical with its axis, described power transmitting and converting device includes housing, and is separately positioned on housing two ends the power intake being connected with power source outfan and the clutch end being connected away from power source with sleeve；It is provided with gear train assembly in described housing。

Described gear train assembly includes being arranged on the power input gear of power intake and being arranged on the power output gear of clutch end。

The gear ratio of described power input gear and power output gear is 1:1。

Described gear train assembly also includes at least one travelling gear being arranged between power input gear and power output gear。

Gear ratio between described power input gear, power output gear and travelling gear is 1:1:1。

Described power input gear is provided with the power intake interface being connected with power source outfan, described power output gear is provided with the clutch end interface being connected with sleeve。

The thickness of described power transmitting and converting device is 16-30mm。

The one of which that described power source is accumulator or wind regime is constituted

The beneficial effects of the utility model are: this utility model is provided with gear train assembly, by increasing travelling gear, torsion is delivered to effect end from power end (source), realizing dynamic torque lateral transport, indirectly shortening axial transmission distance, thus making up the shortcoming that existing power operated wrench instrument rotating shaft axial distance is longer, power operated wrench can be made to enter smaller job space, realization in the purpose of small space torsion transmission, can improve production operation efficiency, reduces human cost。

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model will be further described。

As shown in accompanying drawing 1-5, a kind of power operated wrench for small space, including power source 1, the one of which that described power source 1 is accumulator or wind regime is constituted；Described power source 1 outfan is connected to the power transmitting and converting device 2 vertical with its axis, and the thickness A of described power transmitting and converting device is 16-30mm, adds length sleeve less than power source 1 output shaft shaft length, to be adapted to operation in narrow space；Described power transmitting and converting device 2 includes the housing 3 being made up of steel, and described housing 3 is formed by connecting through fixing connecting hole 7 by bolt by upper and lower casing；Described housing 3 two ends are respectively arranged with the power intake 4 being connected with power source 1 outfan and the clutch end 5 being connected away from power source 1 with sleeve；It is provided with gear train assembly in described housing 3。

Described gear train assembly includes the power input gear 8 being arranged on power intake 4 and the power output gear 9 being arranged on clutch end 5, described power input gear 8 is provided with the power intake interface 11 being connected with power source 1 outfan, described power output gear 9 is provided with the clutch end interface 12 being connected with sleeve, one end input torque, other end output moment of torsion, it is achieved in the purpose of small space torsion transmission；Described gear train assembly may also include at least one travelling gear 10 being arranged between power input gear 8 and power output gear 9, by increasing equal proportion travelling gear 10, power source 1 torsion is delivered to the other end。Wherein, described power input gear 8, power output gear 9 and travelling gear 10 gear ratio each other are 1:1；Additionally, described power input gear 8, power output gear 9 and travelling gear 10 are high-strength gear, and it is fixed in housing and with it for center of rotation by rotary gear axis 6。
