Abstract
The utility model discloses a kind of rotary spanner, it is sleeve-shaped, and is along the circumferential direction evenly equipped with four afterburning holes in wherein one end, and is provided with two relative pin-and-holes on the end face of this end vertically.By this utility model, only need a people to rotate rotary spanner with a boosting-rod when bearing flange is installed and screw is become linear motion, can shift onto bearing flange specify position.Period, it is not necessary to many people coordinate, laborsaving and safety.
Description
Technical field
This utility model relates to installation tool field, particularly relates to a kind of rotary spanner.
Background technology
Prior art is installed short stress rolling mill and supports the bearing flange of seat, it is common that use hand hammer to tap bearing flange,
The most laborious, and it is easily damaged bearing flange.
Summary of the invention
The technical problems to be solved in the utility model is to be installed simply, easily by bearing flange to short stress rolling mill support
On seat.
For reaching above-mentioned purpose, this utility model provides a kind of rotary spanner, and it is sleeve-shaped, and in wherein one end circumferentially
Direction is evenly equipped with four afterburning holes, and is provided with two relative pin-and-holes on the end face of this end vertically.
It is also preferred that the left a diameter of 10.5mm of described pin-and-hole, the degree of depth vertically is 30mm, and the centre-to-centre spacing between two pin-and-holes
For 125mm.
When utilizing above-mentioned rotary spanner that the bearing flange that short stress rolling mill supports seat is installed, its mounting arrangement from inside to outside
Order is: flange, cylinder sleeve, aforesaid rotary spanner, pin and the rotary copper nut of rotation turnback, wherein said rotary copper spiral shell
Female end face is provided with two relative pin-and-holes, and described pin is placed in the pin-and-hole on described rotary spanner and rotary copper nut
In pin-and-hole, insert afterburning hole by boosting-rod and rotate rotary spanner, rotate rotary spanner and copper nut is rotated by pin, push away
Bearing flange to travel forward.
It is also preferred that the left a diameter of 10.5mm of pin-and-hole on described rotary copper nut end face, the degree of depth is 20mm.
It is also preferred that the left the size of described pin is 10mm × 35mm.
This utility model difference from prior art is that this utility model achieves following technique effect:
By this utility model, during installation, only need a people to rotate rotary spanner with a boosting-rod and screw is become
Linear motion, can shift onto bearing flange specify position.Period, it is not necessary to many people coordinate, laborsaving and safety.
The utility model is described in further detail below in conjunction with the accompanying drawings.

Detailed description of the invention
Below in conjunction with embodiment, to this utility model, above-mentioned and other technical characteristic and advantage are made in more detail
Bright.
Referring to Fig. 1, rotary spanner 3 of the present utility model, it is sleeve-shaped, and the most uniform in wherein one end
There are four afterburning holes 32, and on the end face of this end, are provided with two relative pin-and-holes 34 vertically, pin-and-hole 34 a diameter of
10.5mm, the degree of depth vertically is 30mm, and the centre-to-centre spacing between two pin-and-holes is 125mm.
When installing the bearing flange that short stress rolling mill supports seat, mounting arrangement order from inside to outside is: flange 5, cylinder sleeve
4, rotary spanner 3, pin 2 and the rotary copper nut 1 of rotation turnback, wherein the end face of rotary copper nut is provided with two relatively
Pin-and-hole, in pin-and-hole 34 that pin 2 is placed on rotary spanner and the pin-and-hole of rotary copper nut, insert afterburning hole by boosting-rod
32 rotate rotary spanner 3, copper nut 1 are rotated by pin 2, push bearing flange 5 and travel forward.Period, only need a people
Operation can complete installment work, it is not necessary to many people coordinate.In this embodiment, on rotary copper nut end face, pin-and-hole is a diameter of
10.5mm, the degree of depth is 20mm；The size of pin is 10mm × 35mm.
Embodiment described above is only to be described preferred implementation of the present utility model, not to this practicality
Novel scope is defined, and on the premise of without departing from this utility model design spirit, those of ordinary skill in the art are to this
Various deformation that the technical scheme of utility model is made and improvement, all should fall into the protection that this utility model claims determine
In the range of.
