Embodiment
Below, with reference to accompanying drawing and embodiment, the utility model is described further, it is necessary to explanation is,
On the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment.
As shown in Figure 1-2, a kind of main shaft pull bar mounting structure, including mounting assembly (figure do not mark), draw-bar seat 6, shaft core 7 with
Pull bar 9.Mounting assembly includes disc spring gland 1, butterfly spring 2, pad 3, back-up ring gland 4 and back-up ring 5.
The pad 3 is used to adjust the decrement of butterfly spring 2, and the pad of different-thickness can be selected to change thickness.Pad 3
Side abuts with butterfly spring 2, and opposite side abuts with back-up ring gland 4.Back-up ring gland 4 is provided with stepped hole, the diameter of stepped hole
More than the diameter of back-up ring 5.Back-up ring 5 is made up of for that can divide back-up ring two identical semicolumns 51.
During installation, mounting assembly is contained in shaft core 7, and pull bar 9 is movably installed in shaft core 7.Peace is offered on pull bar 9
Tankage 91, two semicolumns 51, which fasten, to be installed in mounting groove 91.Back-up ring 5 is installed between back-up ring gland 4 and draw-bar seat 6.Draw
Pole socket 6 is contained in shaft core 7, the embedding sealing circle 8 on draw-bar seat 6, to increase the sealing that draw-bar seat 6 is connected with shaft core 7.The master
Axle pull bar fixed structure one end abuts with draw-bar seat 6.Disc spring gland 1, butterfly spring 2, pad 3 and back-up ring gland 4 are sequentially socketed
On pull bar 9.
In use, knife striking cylinder applies pressure to draw-bar seat 6, draw-bar seat 6 is by pressure transmission to back-up ring 5.Because the card of back-up ring 5 is put
It is installed in mounting groove 91, back-up ring 5 drives pull bar 9 to move down.At disc spring gland 1, there is shaft core support, therefore pull bar 9 moves down
During butterfly spring 2 compressed.Butterfly spring 2 after compression produces bounce, make back-up ring 5 recover to both sides respectively with pull bar
The state that seat 6, back-up ring gland 4 abut.
In the utility model, because the diameter of stepped hole is slightly larger than the diameter of back-up ring 5, in the elastic masterpiece of butterfly spring 2
Under, it is ensured that back-up ring gland 4 presses back-up ring 5, without departing from the mounting groove 91 of pull bar 9.When butterfly spring 2 is produced compared with your writing
When firmly, the cooperation of back-up ring 5, mounting groove 91 and back-up ring gland 4 more fastens.
Above-mentioned embodiment is only preferred embodiment of the present utility model, it is impossible to is protected with this to limit the utility model
