Utility model content
In view of the shortcomings of the prior art, the purpose of this utility model aims to provide a kind of middle hanging axis for being easy to maintenance and installation and connected
Binding structure.
To achieve the above object, the utility model adopts the following technical scheme that：
For hanging axis attachment structure in the wafer type of screw machine, including
Outer tube；
Mandrel, it is accordingly nested in outer tube, and a groove is provided with the end face of mandrel；
Middle hanging axis component, it includes middle hanging axis, and the boss corresponding with mandrel groove is designed with the both ends of middle hanging axis, convex
Platform is nested in the groove of mandrel, through bearing pin is provided with the nested position of boss and groove, by middle hanging axis component both ends
Mandrel link together；
Hanging axis adpting flange in outer tube, it is symmetrically disposed in outer tube both sides；
Middle hanging axis support, it is installed in outer tube on hanging axis adpting flange, is led between middle hanging axis support and middle hanging axis component
Cross and folder mode is attached.
The middle hanging axis component also includes being nested in middle hanging axis outer wall upper copper sheathing and hanging in being nested on copper sheathing outer wall
Axle bed, one is formed between the middle hanging axis, copper sheathing and middle hanging axis seat three.
Oilhole is provided with the middle hanging axis support, the oil being connected with oilhole is provided with copper sheathing and middle hanging axis seat
Groove.
The middle hanging axis support, which is adopted, to be tightened by bolts in outer tube on hanging axis adpting flange.
Oil sealing is installed in the oil groove.
The beneficial effects of the utility model are：
Middle hanging axis attachment structure of the present utility model is due to middle hanging axis with the connection of mandrel using with bumps nested ten
Middle hanging axis and two mandrels are connected to form one by the form that couplet connects, and rotary torsion are transmitted by the nested form of convex-concave, with convex
Recessed axial end positions axial gap, and is rotated by 90 ° the vertical plane in direction at its convex-concave nested position with bearing pin locking notch footpath
To motion, hanging axis support can adjust position of the mandrel in outer tube, when installation and debugging are repaired, Ke Yi surely to clamping in utilization
In the case of not dismantling outer tube and mandrel, by unloading middle hanging axis support and bearing pin, it is possible to middle hanging axis component is removed, from
And make it that installation and debugging are convenient, use cost is lower.

Embodiment
Below, with reference to accompanying drawing and embodiment, the utility model is described further：
Shown in Figure 2, the structure of hanging axis attachment structure is shown in the wafer type for screw machine provided for the present embodiment
It is intended to, hanging axis attachment structure includes outer tube 1 in this；Mandrel 2, mandrel 2 are accordingly nested in outer tube 1, are set in the end face of mandrel 2
It is equipped with a groove；Middle hanging axis component, it includes middle hanging axis 3, is designed with the both ends of middle hanging axis 3 corresponding with mandrel groove convex
Platform 31, boss 31 are nested in the groove of mandrel, run through being provided with bearing pin 4 at the nested position of boss 31 and groove, will
The mandrel 2 at middle hanging axis component both ends links together；Hanging axis adpting flange 5 in outer tube, it is symmetrically disposed in 1 liang of outer tube
Side；Middle hanging axis support 6, it is installed in outer tube on hanging axis adpting flange 5, is passed through between middle hanging axis support 6 and middle hanging axis component
Clip-on mode is attached, and is locked after connection with bolt 9, in order to the assembly and disassembly of middle hanging axis support 6.
As can be seen here, middle hanging axis attachment structure of the present utility model is because the both ends of middle hanging axis are using with concavo-convex nested
The mandrel 2 at middle hanging axis group both ends is connected to form one by the form of cross connector, is rotated by the nested form transmission of convex-concave
Torsion, axial gap is positioned with convex-concave axial end, and the vertical plane in direction is rotated by 90 ° with bearing pin at its convex-concave nested position
Locking notch radial motion, by using such structure, when installation and debugging are repaired, outer tube 1 and mandrel 2 can not dismantled
In the case of, by unloading middle hanging axis support 6 and bearing pin 4, it is possible to remove middle hanging axis component, so that installation and debugging side
Just, use cost is lower.Meanwhile hanging axis support 6 can adjust position of the mandrel 2 in outer tube 1 surely to clamping in can utilizing, with
Convenient adjustment concentricity.
Specifically, above-mentioned middle hanging axis component also includes the copper sheathing 7 being nested on the middle outer wall of hanging axis 3 and is nested in copper sheathing
Middle hanging axis seat 8 on 7 outer walls, hanging axis 3, copper sheathing 7 and middle hanging axis seat 8 three in can causing in the presence of middle hanging axis support 6
