Specific embodiment
As depicted in figs. 1 and 2, the pusher provided in this embodiment with bellows includes push rod 1 and push cylinder 2,
The top of push rod 1, which is fixed with, cuts somebody's hair, and the bottom end of push rod 1 is equipped with workpiece fixing port 12, and the both ends of the push cylinder 2 are fixed with upper end
Lid 21 and bottom end cover 22, push rod 1 pass through upper end cover 21 and bottom end cover 22, bellows component, ripple are provided in the push cylinder 2
Tube assembly includes pressure head 5 and bellows 6, and pressure head 5 is fixedly connected with push rod 1 and is slided with push rod 1, and bellows 6 is actively socketed on
On push rod 1 and between pressure head 5 and bottom end cover 22.
The top of the push rod 1 offers compression and rises as high as the banks 11, and the notch for compressing 11 both ends of rising as high as the banks is located at upper end cover 21 respectively
Both sides up and down, limited by can rise as high as the banks to compression 11 both ends of upper end cover 21, compressing 11 length of rising as high as the banks can be according to need
Design is sought, threaded hole is offered on the anchor ring with compressing 11 corresponding upper end covers 21 of rising as high as the banks, housing screw is combined in threaded hole
3, when push rod 1 pushes in place, the locking of push rod 1 is realized by tightening housing screw 3.
Observation panel 23 is further opened on the housing of the push cylinder 2, graduation mark is provided at observation panel 23, observation panel 23 is used
In the position of observation 5 upstream or downstream of pressure head, while instruction graticule is provided on the anchor ring of pressure head 5, can be obtained according to instruction graticule
Go out the distance of 5 upstream or downstream of pressure head.
The bottom of the bottom end cover 22 is connected with vacuum flange 4, and in the present embodiment, vacuum flange 4 is one with bottom end cover 22
It is body formed, guide flange 7, guide flange 7 and 1 pivot bush unit of push rod, the lower end are installed at the central bore of vacuum flange 4
The center of lid 22 is opened up there are one being more than 1 diameter of push rod and less than the hole of 6 diameter of bellows, the through-hole on 7 end face of guide flange
It is connected by the hole with 6 inner cavity of bellows, seal groove 41 is additionally provided at the bottom nozzle of 4 endoporus of vacuum flange.
The operation principle of the utility model is：By reaction crucible or other workpiece at the workpiece fixing port 12 of push rod 1
It is stretched into vacuum plant after fixing, the flange corresponding on vacuum plant of vacuum flange 4 is mutually locked, as needed pushes away
Distance is sent to push push rod 1, different station is converted in vacuum plant so as to fulfill reaction crucible or other workpiece.
The above is only the utility model preferred embodiment, but the scope of protection of the utility model is not limited to
This, any transformation carried out based on technical solution provided by the utility model and inventive concept and replacement should all be covered in this reality
With in novel protection domain.
