Abstract

The utility model relates to a pneumatic or electric wrench auxiliary tool which comprises a seat, a driving shaft and a driven shaft respectively arranged at both ends of the seat, a transmission cover and a driving gear arranged on the driving shaft, and a rotating jacket and a driven gear arranged on the driven shaft. The transmission cover is provided with a square inner hole which engages with the head part of the transmission shaft of a pneumatic or electric wrench. The rotating jacket is provided with cavities engaging with the head parts of a nut and a bolt respectively. When in use, the head part of the transmission shaft of the pneumatic or electric wrench is inserted into the square inner hole of the transmission cover and the head part of the nut or the bolt to be disassembled is embedded in the cavity of the rotating jacket, the pneumatic or electric wrench is operated and the rotational torque is transferred to the rotating jacket by means of the gear engagement, and the rotating jacket drives the nut or the bolt to rotate, thereby fastening or loosening the nut or the bolt. The pneumatic or electric wrench auxiliary tool allows the pneumatic or electric wrench to easily assemble or disassemble the nut and the bolt under the condition that the spatial position of the wrench is small.

Description

Pneumatic or electric wrench aid
Technical field
The utility model relates to pneumatic or the electric wrench technical field, especially a kind of pneumatic or electric wrench aid.
Background technology
Pneumatic or electric wrench is a kind of common tool of installing and removing bolt and nut, because of its moment of torsion big, high efficiency and being widely used, common bolt and nut connection has bigger spanner space, can directly use pneumatic or electric wrench is installed and removed bolt and nut, but also can be subjected to the restriction of locus sometimes, as the foundation bolt of plant equipment, the connection between some member, because claimed structure compactness, the position is special, can not stay very big spanner space, thereby just can not directly use pneumatic or electric wrench is installed and removed bolt and nut, and adopt manual wrench to install and remove bolt and nut, efficient is low, the trouble effort, furthermore people's strength is limited, what may cause that bolt and nut twists is tight inadequately, influence is the normal use of equipment later on, also might damage the profile of nuts and bolt head, dismounting difficulty after causing.
The utility model content
The technical problems to be solved in the utility model is: a kind of pneumatic or electric wrench aid is provided, and it can be less in the spanner space, under the special situation in position, also can use pneumatic or electric wrench is installed and removed bolt and nut efficiently and easily.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of pneumatic or electric wrench aid, has pedestal, driving shaft and driven shaft are separately positioned on the two ends of pedestal, driving shaft is provided with driving gear, the input of driving shaft is provided with the drive sleeve that but air feed is moving or electric wrench power transmission shaft head stretches into, driven shaft is provided with driven gear, and the output of driven shaft is provided with dismountable rotational sleeve.
When described driving gear and driven gear are spur gear, be provided with a transition axis at least between driving shaft and driven shaft, transition axis is provided with transition gear, and driving gear drives driven gear by transition gear and rotates; When described driving gear and driven gear adopt Bevel Gear Transmission, can realize the central vertical break-in of driving shaft and driven shaft.
Described drive sleeve has and cubic endoporus pneumatic or that electric wrench power transmission shaft head matches; rotational sleeve has the cavity identical with the nuts and bolt head configuration; be provided with lining between rotational sleeve and the driven shaft output; the three connects by pin; the drive sleeve outer periphery is equipped with protective sleeve, protective sleeve by bolting on pedestal.
Described pedestal two opposites are provided with dust cover.
The beneficial effects of the utility model are after the utility model adopts above scheme, can have specific position, under the less situation in spanner locus, can use pneumatic easily or electric wrench is installed and removed bolt and nut, reach time saving and energy saving, safely and efficiently purpose.
