Abstract
The utility model relates to an electric wrench which comprises a machine shell which is in a T-shaped structure and a power source component which is connected with the bottom of the machine shell. A motor, a motor gear which is connected with a motor shaft rod, a gear case, an impacting assembly, and an output shaft are mounted in a lateral cavity of the machine shell, wherein the gear case is meshed with the motor gear. A switch driving lever which is connected with the motor and a switch which is connected with the switch driving lever are mounted in the machine shell. An outlet is arranged at the bottom of the machine shell, and the outlet is connected with the switch. The motor shaft rod is connected with one end of the outlet shaft through the impacting assembly. According to the electric wrench, the design of the gear case is adopted, so output torque of a motor shaft is increased, impact of the motor shaft is increased, and nuts are easy to demount under the effect of the impact.
Description
Technical field
The utility model relates to the field of electric tool, especially a kind of electric wrench.
Background technology
Electric wrench be exactly power supply or battery be the spanner of power, be a kind of instrument that tights a bolt.Mainly be divided into impact wrench, turn round and cut spanner, constant torque wrench, corner spanner, angle spanner, hydraulic spanner, torque spanner, charged electric spanner.Electric wrench is mainly used in the Steel Structure Installation industry, and the steel construction high-strength bolt is installed specially, and high-strength bolt is used for connecting the steel construction contact, and normally the mode with the bolt group occurs.
The electric impact wrench that uses mainly is just tight bolt at present, and its use is very simple, aims at bolt exactly and pulls power switch just.Electronicly turn round that to cut spanner mainly be whole tight torque-shear type high-strength bolt, its use is exactly to aim at bolt to pull power switch, till the wabbler of torque-shear type high-strength bolt is interrupted.Electronic constant torque wrench not only can be just tightly but also can be tight eventually, its use is to regulate moment of torsion, fastening bolt more earlier.Electronic corner spanner mainly also belongs to a kind of of constant torque wrench, and its use is to regulate the rotation number of degrees, fastening bolt more earlier.Electronic angle spanner is the electric wrench of a kind of special fastening steelframe angle position bolt, and its use turns round with electronic that to cut the spanner principle the same.
Because its impulsive force of employed electric wrench is not enough in above-mentioned, be easy to generate and turn round not that Broken bolt causes the motor burnout phenomenon, cause damage.
The utility model content
The technical problems to be solved in the utility model is: in order to overcome the above-mentioned middle problem that exists, provide a kind of electric wrench, its project organization is reasonable, easy to use and impulsive force is big, moment of torsion is big.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of electric wrench, comprise the casing with T type structure and the power supply module that is connected bottom of shell, in the transverse chambers of described casing motor is installed, be connected the motor gear on the motor axostylus axostyle, the gear-box that is meshed with motor gear and impact assembly and output shaft, the switch driving lever that is connected with motor and the switch that is connected with the switch driving lever are installed on the described casing, described bottom of shell is provided with supply socket, supply socket is connected with switch, and described motor axostylus axostyle links to each other with output shaft one end by impacting assembly.
Power brick in described power supply module comprises shell and shell is set and the battery lead plate that is connected with power brick, shell are plugged on the casing below and are electrically connected by battery lead plate and supply socket.
Described impact assembly comprises striker and the spring that is installed in the casing, and an end of spring is embedded in the striker, and the other end peaks on the gear-box.
In order to strengthen the intensity of casing front end, to avoid damaging, described casing front end sleeve is equipped with the aluminium head capsule, and output shaft one end passes the aluminium head capsule.
The beneficial effects of the utility model are that a kind of electric wrench of the present utility model adopts the design of gear-box, and the motor shaft output torque is increased, and increases its impulsive force, makes nut easily unloading under impact force action.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
1. casings among the figure, 21. shells, 22. power brick, 23. battery lead plates, 3. motor, 4. motor gear, 5. gear-box, 61. strikers, 62. springs, 7. output shaft, 8. switch driving lever, 9. switch, 10. supply socket.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of electric wrench as shown in Figure 1, comprise the casing 1 with T type structure, be equipped with aluminium head capsule 11 at casing 1 front end sleeve, be provided with supply socket 10 in casing 1 bottom, at casing 1 bottom plant power supply module, power supply module and supply socket 10 are electrically connected, motor 3 is installed in the transverse chambers of casing 1 successively, be connected the motor gear 4 on motor 3 axostylus axostyles, the gear-box 5 that is meshed with motor gear 4 and impact assembly and output shaft 7, motor 3 axostylus axostyles link to each other with output shaft 7 one ends by impacting assembly, output shaft 7 one ends pass aluminium head capsule 11, the switch driving lever 8 that is connected with motor 3 and the switch 9 that is connected with switch driving lever 8 are installed in the outside of casing 1, switch 9 is electrically connected with supply socket 10
A kind of electric wrench of the present utility model impacts assembly and comprises striker 61 and the spring 62 that is installed in the casing 1, and an end of spring 62 is embedded in the striker 61, and the other end peaks on the gear-box 5.
