Embodiment
Below, with reference to accompanying drawing and embodiment, the present invention is described further, it is necessary to which explanation is, not
Under the premise of afoul, new implementation can be formed between various embodiments described below or between each technical characteristic in any combination
Example.
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 for the decrement for adjusting butterfly spring 2, can select the pad of different-thickness to change thickness.Pad 3
Side is abutted with butterfly spring 2, and opposite side is abutted 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 are fastened, 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 is abutted 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 is moved 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 are abutted.
In the invention, because the diameter of stepped hole is slightly larger than the diameter of back-up ring 5, under the resilient force of butterfly spring 2,
It can ensure 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 noticeable effort
When, the cooperation of back-up ring 5, mounting groove 91 and back-up ring gland 4 is more fastened.
Above-mentioned embodiment is only the preferred embodiment of the present invention, it is impossible to limit the scope of protection of the invention with this,
The change and replacement for any unsubstantiality that those skilled in the art is done on the basis of the present invention belong to institute of the present invention
Claimed scope.
