Detailed description of the invention
Your further understand and approval, hereby for making juror can inventive feature and its feature be had
Enumerate following preferred embodiment and coordinate graphic being described as follows:
Refer to Fig. 1 to Fig. 5, be the additional of a kind of gantry processor of being provided of a preferred embodiment of the present invention
Axle clamping device 100, in order to a main shaft 91 and an additional shaft 92 are combined and to be separated, it mainly comprises
There are cover body 30 in an outer outlet body 10, some springs 20, some fixture blocks 40 and a locating dowel 50,
Wherein:
Refer to Fig. 1 to Fig. 5, this outer outlet body 10, it is arranged at the room that this main shaft 91 is offered actively
In 911, and position can be pushed up on one by External Force Acting and carry out reciprocal displacement between push position once, this outer housing
It is all from the outer housing of this outer housing roof 11 periphery downward ring-type extension of one that body 10 has an outer housing roof 11 and
Wall 12, has one and pushes inclined-plane 121 inside the ora terminalis of this outer housing perisporium 12.
Refer to Fig. 1 to Fig. 5, this some spring 20, it is connected to diapire and this outer housing of this room 911
Between the outer housing roof 11 of body 10, to be bestowed this outer outlet body 10 1 towards this lower pushing by this some spring 20
The elastic prestressing that set moves.
Refer to Fig. 1 to Fig. 5, this interior cover body 30, there is an inner cover roof 31 and from this inner cover roof 31
The inner cover perisporium 32 of the periphery downward ring-type extension of one, this inner cover roof 31 is positioned at the outer housing of this outer outlet body 10
In perisporium 12, this inner cover perisporium 32 is then fixed on interlocking, and this inner cover perisporium 32 with this main shaft 91 and opens
It is provided with some displacement aperture 321 according to equidistant annular arrangement.
Refer to Fig. 1 to Fig. 5, this some fixture block 40, it is respectively placed in the displacement aperture 321 of this interior cover body 30
In, and can by External Force Acting be carried out in this displacement aperture 321 between a clip position a to release position past
Complex displacement, this fixture block 40 the inner has one towards the clipping cambered surface 41 within this inner cover perisporium 30, this fixture block
Then have one between 40 outer ends and end face and pushed away inclined-plane 42, between this clipping cambered surface 41 and end face, then there is a fixture block
Cammed surface 43.
Refer to Fig. 1 to Fig. 5, this locating dowel 50, there is a head 51, all over the body portion 52 and and be connected to this
Cervical region 53 between head 51 and this body portion 52, and the external diameter of this cervical region 53 is less than this head 51 and this body portion
The external diameter of 52, has a locating dowel cammed surface 54 between this cervical region 53 and this head 51, this body portion 52 interlocking
It is fixed on this additional shaft 92.
Therefore the above-mentioned additional axle clamp being a kind of gantry processor that a preferred embodiment of the present invention is provided
Hold mechanism 100 each portion component and the introduction of assembling mode thereof, the most again its handling characteristics be described as follows:
When being intended to be combined this additional shaft 92 with this main shaft 91, first hydraulic oil is flow into this outer outlet body 10
And between this interior cover body 30, as it is shown on figure 3, now this outer outlet body 10 is past by the pressure effect of this hydraulic oil
Upper top position displacement, makes to be resisted the elastic force of this spring 20 by this outer outlet body 10 and then compress this spring 20, connects
And this locating dowel 50 is penetrated toward inner cover perisporium 32 inside of this interior cover body 30, treat the neck of this locating dowel 50
When portion 53 is positioned at the correspondence position of this displacement aperture 321, just this hydraulic oil can be released, make this outer outlet body 10
Pushed by this spring 20 once again and down push position moves, and moved in this outer outlet body 10 down push position
While, pushing inclined-plane 121 and can push against and pushed away on inclined-plane 32 in this fixture block 40 on this outer outlet body 10,
Make this fixture block 40 be moved toward clip position from release position, and be connected to by the clipping cambered surface 41 of this fixture block 40
On the cervical region 53 of this locating dowel 50, and it is connected to this locating dowel 50 by the fixture block cammed surface 43 of this fixture block 40
Locating dowel cammed surface 54 on (as shown in Figure 4), and outer housing perisporium 12 medial surface of this outer outlet body 10 is also
Gear is butted on the outer end of this fixture block 40, makes fixture block 40 position now fix, and then reaches this additional shaft
92 purposes being combined with this main shaft 91.
Therefore the locating dowel cammed surface 54 of fixture block cammed surface 43 and this locating dowel 50 due to this fixture block 40
Mutually abutting, and now this fixture block 40 is kept off to moving by this outer outlet body 10, this outer outlet body 10 is then
Pushed against by this spring 20, therefore formed self-locking state, taken off with main shaft 91 voluntarily in case this additional shaft 92 has
From the facts occur.
Moreover, owing to relying on fixture block cammed surface 43 and locating dowel cammed surface between this fixture block 40 and this locating dowel 50
54 mutually abut and clamp, can produce clamping effect the most firm hence with cammed surface.Furthermore, this
Stroke needed for invention is shorter, and is effectively reduced volume.
When being intended to separate this additional shaft 92 with this main shaft 91, the most once again hydraulic oil is flow into this outer outlet body
Between 10 and this interior cover body 30, as it is shown in figure 5, now this outer outlet body 10 by this hydraulic oil pressure effect and
Up push up position displacement, make to be resisted the elastic force of this spring 20 by this outer outlet body 10 and then compress this spring 20,
Now this fixture block 40 no longer by this outer outlet body 10 kept off to, and can stress from clip position toward release position move
Dynamic, make this locating dowel 50 depart from the clamping of this fixture block 40, and this additional shaft 92 can be added with this main shaft 91
To separate.
Secondly, although in above-described embodiment, the gabarit moulding of this fixture block is the most cylindrical；But, it practice,
As shown in Figure 6, the gabarit moulding of this fixture block 40 also can be generally in round bead shape, and it also can reach identical effect.
It addition, as shown in Figure 4, have more one between this fixture block 40 outer end and bottom surface and abut against inclined-plane 44；This outer housing
Outer housing perisporium 12 medial surface of body 10 also has a gear and supports inclined-plane 122, when this outer outlet body 10 is positioned at lower pushing
When putting, this gear pushes to inclined-plane 122 and abuts against on inclined-plane 44 in this, so that this fixture block 40 Wei Te is being clamped position
Put place.
Furthermore, in above-described embodiment, this fixture block cammed surface 43 is radiused ramp with this locating dowel cammed surface 54；
This pushes inclined-plane 121 and should be pushed away inclined-plane 42 is radiused ramp；This abuts against inclined-plane 44 and supports inclined-plane 122 with this gear
For radiused ramp.
Described above it is merely exemplary for the purpose of the present invention, and nonrestrictive, ordinary skill people
Member understand, in the case of the spirit and scope limited without departing from claim, can many modifications may be made,
Change or equivalence, but within falling within protection scope of the present invention.
