Abstract
The utility model discloses a kind of novel biaxial tightening device, including metal shell, electric wrench connecting shaft, driven helical gear, first output shaft, active oblique gear and the second output shaft, the electric wrench connecting shaft is connected with the active oblique gear, the driven helical gear is two, the first output driven helical gear of axis connection one, another described driven helical gear of the second output axis connection, the ratcheting connection in both sides with the active oblique gear respectively of two driven helical gears, the driven helical gear and the active oblique gear are respectively positioned in the metal shell.Compared with prior art, the utility model using when be used together with electric wrench, electric wrench drives tightening device to realize that twin shaft rotates with power in the same direction, it is simple in construction, by adjust three helical gears, complete working shaft away from change, so as to add the usable range of twin shaft spanner；Value with popularization and application.
Description
Technical field
A kind of U-bolt or double bolt and nuts while the device tightened are the utility model is related to, more particularly to it is a kind of new
Twin shaft tightening device.
Background technology
For a long time, the accessory that U-bolt or double bolt and nuts are tightened simultaneously in electrification railway contact net construction is relative
Increase, it is a very important job that double bolts, which are tightened,.At present, tighten used tool be can only the bilateral alternately spanner tightened
The twin shaft spanner of instrument and inflexible wheel base.Existing instrument is tightened bolt both sides when using common wrench and alternately fastened, easily
Cause both sides bolt to appear inequality, cause fastening torque of bolt different, accessory is easily damaged, and increase is dangerous, and common twin shaft is pulled
The pitch of hand is fixed, and when the pitch of bolts of accessory is improper, twin shaft spanner can not use, these instruments necessarily improve,
Innovate, it is necessary to which a kind of new adjustable shaft is away from twin shaft tightening device.
Utility model content
The purpose of this utility model is that to solve the above problems and provides a kind of novel biaxial tightening device.
The utility model is achieved through the following technical solutions above-mentioned purpose：
The utility model includes metal shell, electric wrench connecting shaft, driven helical gear, the first output shaft, active helical teeth
Wheel and the second output shaft, the electric wrench connecting shaft are connected with the active oblique gear, and the driven helical gear is two, institute
State the driven helical gear of the first output axis connection one, another described driven helical gear of the second output axis connection, two
The ratcheting connection in both sides with the active oblique gear, the driven helical gear and the active are oblique respectively for the individual driven helical gear
Gear is respectively positioned in the metal shell.
The beneficial effects of the utility model are：
The utility model is a kind of novel biaxial tightening device, compared with prior art, when the utility model uses and electronic
Spanner is used together, and electric wrench drives tightening device to realize that twin shaft rotates with power in the same direction, simple in construction, by adjusting three helical teeth
Wheel, complete working shaft away from change, so as to add the usable range of twin shaft spanner；Value with popularization and application.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1- metal shells, 2- electric wrenches connecting shaft, the driven helical gears of 3-, the output shafts of 4- first, 5- active helical teeth
Wheel, the output shafts of 6- second.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in Figure 1：It is defeated that the utility model includes metal shell 1, electric wrench connecting shaft 2, driven helical gear 3, first
Shaft 4, the output shaft 6 of active oblique gear 5 and second, the electric wrench connecting shaft 2 is connected with the active oblique gear 5, described
Driven helical gear 3 is two, and first output shaft 4 connects a driven helical gear 3, and second output shaft 6 connects
Another described driven helical gear 3, the ratcheting connection in both sides with the active oblique gear 5 respectively of two driven helical gears 3,
The driven helical gear 3 and the active oblique gear 5 are respectively positioned in the metal shell 1.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within claimed the scope of the utility model.The utility model
Claimed scope is by appended claims and its equivalent thereof.
