Description
Technical field
The utility model belongs to machining tools art, and in particular to a kind of diagonal tools for bolts ' pretension device of adjustable pitch formula.
Background technology
Currently, many device connections with sealing ring are frequently with the connection type of symmetrical bolt group, this symmetrical bolt
Group is arranged in machinery, hydraulic pressure assembly, vehicle and aerospace etc. using especially prominent.The pre- tight end of symmetrical bolt group
It often needs by diagonally installing each bolt, to ensure that the seals and other component stress below each bolt and contact surface is good,
Using traditional approach, using common spanner, efficiency is often relatively low, and operation is also inconvenient, it is difficult to satisfy the use demand.
Utility model content
To solve problem of the prior art, the utility model provides a kind of diagonal tools for bolts ' pretension device of adjustable pitch formula, this
Utility model can be such that the bolt being arranged symmetrically synchronizes to screw, achieve the purpose that bolt group is made uniformly to carry.
In order to achieve the above objectives, the utility model adopts the following technical solution：
A kind of diagonal tools for bolts ' pretension device of adjustable pitch formula, includes the main shell for the font of falling bifurcation, main shell include main channel and
Two branched bottoms of main channel bottom are symmetrically connected to, primary transmission axis, the bottom of primary transmission axis are interspersed on main channel
By the connection of level-one Bevel Gear Transmission group there are two secondary drive shaft, two secondary drive shafts are separately positioned on two branched bottoms
In, two secondary drive shafts are separately connected a three-level transmission shaft, and three-level transmission shaft is connected to by two level Bevel Gear Transmission group
The bottom of level Four transmission shaft, level Four transmission shaft is connected with sleeve, and time shell is equipped on the outside of three-level transmission shaft and level Four transmission shaft, and
Secondary shell is connected with main shell by adjusting screw.
Further, primary transmission axis is connect by angular contact ball bearing seat group with main channel.
Further, secondary drive shaft is connected with three-level transmission shaft by spline.
Further, secondary drive shaft, three-level transmission shaft and level Four transmission shaft are carried out by shaft end with time shell axial
It is fixed.
Compared with prior art, the utility model has technique effect beneficial below：
The utility model is simple in structure, reasonable design, and bolt that can be diagonal to two simultaneously carries out operation, is suitable for needing
Want the place of diagonal screw while fastening, in addition the device can by adjusting the relative position relation of time shell and main shell,
And then the spacing between two sleeves is adjusted, different screw pitch environment are suitable for, and using simply, conveniently, improve working efficiency.

It being wrapped up by secondary shell 4 outside grade transmission shaft 11 and level Four transmission shaft 7, secondary shell 4 is fixed with main shell 3 by adjusting screw 8, and two
Grade transmission shaft 10, three-level transmission shaft 11 and level Four transmission shaft 7 carry out axial restraint by shaft end and time shell 4.
The utility model is described in detail using process with reference to embodiment：
Before use, suitable sleeve 6 is changed, by adjusting adjusting screw 8 and then change time 4 extension elongation of shell, into
And distance between two sleeves 6 is adjusted, so that it is met real work needs.In use, being passed to level-one by using tools such as spanners
Moving axis 1 is rotated, and primary transmission axis 1 drives secondary drive shaft 10 to be rotated by level-one Bevel Gear Transmission group 2, and two level passes
Moving axis 10 drives three-level transmission shaft 11 to rotate by spline fitted, and three-level transmission shaft 11 is driven by two level Bevel Gear Transmission group 5
Level Four transmission shaft 7 is rotated, and band moving sleeve 6 rotates level Four transmission shaft 7 in turn, and then completes the preload mesh to corner bolt
's.
