Abstract
An electric wrench lengthening device applicable to a narrow space comprises a casing. A vertical gear and a horizontal gear matched with each other are arranged in the casing, the horizontal gear is connected with a horizontal shaft, the vertical gear is connected with a vertical shaft, the horizontal shaft and the vertical shaft penetrate a swinging-resisting bearing, two thrust bearings are arranged on the casing and matched with large-diameter faces of the vertical gear and the horizontal gear. By arranging a pair of bevel gears perpendicular to each other, the torque direction is changed while power is transferred, so that the electric wrench can operate in the narrow space. The thrust bearing can improve the working stability of the bevel gears, friction is reduced, the swinging-resisting bearing can reduce vibration of the horizontal shaft and the vertical shaft, and normal work of the electric wrench is guaranteed. By means of the device, the electric wrench can be applicable to the narrow space, possible locking, slipping and damaging of bolts are avoided, materials are saved, working efficiency is improved, and labor resource is saved.
Description
Technical field
The utility model belongs to electric tool technical field, is specifically related to a kind of electric wrench length extension device that is applicable to narrow space.
Background technology
Current electric wrench is mainly divided into three parts: electric gun, extension bar and sleeve.Three parts are by general joint and connect hole and link together, and drive rotation together, thereby reach the effect of tightening or loosering a bolt by electric gun.But because the volume of himself is larger, when run in comparatively narrow space bolt time, electric wrench just cannot play a role, and can only lean on manually operation.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of electric wrench length extension device that is applicable to narrow space, this device can change the direction of moment, can make electric wrench with bolt parallel direction on the smaller volume of part, thereby be convenient to use in narrow space.
The purpose of this utility model is achieved in that a kind of electric wrench length extension device that is applicable to narrow space, comprise housing, in housing, be provided with the vertical gear and the horizontal gear that cooperatively interact, horizontal gear is connected with trunnion axis, vertical gear is connected with vertical axis, trunnion axis and vertical axis through antihunting bearing, are also provided with two thrust bearings respectively on housing, coordinate respectively with the major diameter face of vertical gear and horizontal gear.
Described vertical gear and horizontal gear are a pair of orthogonal conical gear.
Described trunnion axis front end is provided with connecting hole.
Described vertical axis is provided with universal joint.
The electric wrench length extension device of what the utility model provided be applicable to narrow space by a pair of mutually perpendicular conical gear is set, has changed the direction of moment, to adapt to the operation of electric wrench in narrow space in transferring power; Thrust bearing can be strengthened the job stability of conical gear, reduces friction, and antihunting bearing can reduce the vibration of trunnion axis and vertical axis, thereby has ensured the normal work of electric wrench.Can make electric wrench be applicable to narrow space by the utility model, reduce that bolt is contingently killed, slide fastener and damage phenomenon, thereby save material goods and materials, improve operating efficiency, save human resources.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Structure of the present utility model is as shown in Figure 1: a kind of electric wrench length extension device that is applicable to narrow space, comprise housing 5, in housing 5, be provided with the vertical gear 6 and the horizontal gear 7 that cooperatively interact, horizontal gear 7 is connected with trunnion axis 9, and vertical gear 6 is connected with vertical axis 8, and trunnion axis 9 and vertical axis 8 are respectively through antihunting bearing 2,2 ', on housing 5, be also provided with two thrust bearings 3,3 ', coordinate with the major diameter face of vertical gear 6 and horizontal gear 7 respectively.Antihunting bearing and thrust bearing can limit the swing of diaxon.Two thrust bearings 3,3 ' all adopt plain thrust bearing.
Described vertical gear 6 and horizontal gear 7 are a pair of orthogonal conical gear.
Described trunnion axis 9 front ends are provided with connecting hole 4.
Described vertical axis 8 is provided with universal joint 1.
Connecting hole 4 in the utility model is a general connecting hole, when use, the trunnion axis 9 that is provided with connecting hole 4 is connected with electric gun, vertical axis 8 with universal joint 1 is connected with sleeve, electric gun drives trunnion axis 9 to rotate, drive vertical axis 8 to rotate by horizontal gear 7 with vertical gear 6, reach the object of carry-over moment and change aspect, thereby realize the operation of electric wrench at narrow space.
