For achieving the above object, this utility model is by the following technical solutions:
A kind of valve rod clamping mechanism for valve stem packing ring kludge described in the utility model, including dividing
Scale and be installed on the fixture on described index dial, described fixture includes chuck body, clamping plate and clamping bullet
Spring, described clamping plate are hinged with described chuck body, are formed with use between described clamping plate and described chuck body
In the clamping gap of clamping valve rod, described fastening spring supports and is located between described chuck body and described clamping plate；
The outer end of described clamping plate stretches out in the outside of described chuck body, and the side of described index dial is provided with and institute
State the triggering device of the outer end corresponding matching of clamping plate；
When the outer end of described clamping plate contacts with described triggering device, described clamping plate are at described triggering device
Rotate relative to described chuck body under conflict effect, promote described clamping gap to increase, and described folder
Tight spring is compressed；When the outer end of described clamping plate separates with described triggering device, described clamping plate are described
Reset under the elastic force effect of fastening spring, promote described clamping gap shrinks.
Further, described chuck body includes fixing the pedestal being connected, described clamping plate with described index dial
Hinged with described pedestal, described fastening spring supports and is located between described pedestal and described clamping plate；Described pedestal
Inside it is provided with and the fixture block of described clip board engagement, between described fixture block and described clamping plate, is formed with described clamping
Gap.
Further, described triggering device include lift cylinder and with the outer end corresponding matching of described clamping plate
Limit assembly, described limit assembly is in transmission connection with the outfan of described lift cylinder.
Further, described limit assembly includes mounting seat, installs axle and Limit Bearing, described installation axle
Being in transmission connection with described lift cylinder by described mounting seat, described Limit Bearing is installed in described installation axle
On.
The beneficial effects of the utility model are: this utility model provide for valve stem packing ring kludge
Valve rod clamping mechanism, during work, is driven fixture to rotate by index dial, when outer end and the triggering device of clamping plate
During contact, clamping plate rotate relative to chuck body under the barrier effect triggering device so that clamping gap
Increase, the most just can put into or take out valve rod；When the outer end of clamping plate separates with triggering device, clamping plate
Then reset under the elastic force effect of fastening spring so that clamping gap shrinks, the most just can be by valve lever clamp
Fasten.
In sum, this utility model is simple and reasonable, and manufacturing cost is relatively low, it is possible to it is right effectively to realize
The clamping of valve rod workpiece or unclamp, automaticity is higher, controls more convenient.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.
A kind of valve rod clamping mechanism for valve stem packing ring kludge as shown in Figure 1, including index dial 1
And it being installed on the fixture on index dial 1, fixture includes that chuck body 2, clamping plate 3 and fastening spring are (in figure
Not shown), clamping plate 3 are hinged with chuck body 2, are formed for pressing from both sides between clamping plate 3 and chuck body 2
The clamping gap 4 of tight valve rod 9, fastening spring supports and is located between chuck body 2 and clamping plate 3.
Specifically, chuck body 2 includes the pedestal 21 that be connected fixing with index dial 1, clamping plate 3 and base
Seat 21 is hinged, and fastening spring supports and is located between pedestal 21 and clamping plate 3；It is provided with and clamping plate in pedestal 21
3 fixture blocks 22 coordinated, are formed with clamping gap 4 between fixture block 22 and clamping plate 3.
The outer end of clamping plate 3 stretches out in the outside of chuck body 2, and the side of index dial 1 is provided with and clamping plate 3
The triggering device of outer end corresponding matching.Trigger device and include lift cylinder 5 and the outer end pair with clamping plate 3
The limit assembly that should coordinate, limit assembly is in transmission connection with the outfan of lift cylinder 5.Limit assembly bag
Include mounting seat 6, axle 7 and Limit Bearing 8 are installed, axle 7 is installed and is passed with lift cylinder 5 by mounting seat 6
Being dynamically connected, Limit Bearing 8 is installed on installation axle 7.By using Limit Bearing 8, it is possible to effectively reduce
Frictional force during limit assembly lifting moving and between clamping plate 3, reduces the vibrations that clamping plate 3 are subject to, and protects
Demonstrate,prove the stability of valve rod 9 clamping.
When the outer end of clamping plate 3 contacts with triggering device, clamping plate 3 are phase under the conflict effect triggering device
Chuck body 2 is rotated, promotes clamping gap 4 to increase, and fastening spring is compressed；When clamping plate 3
Outer end with trigger device separate time, clamping plate 3 reset under the elastic force effect of fastening spring, promote clamping
Gap 4 reduces.
Specifically, during work, index dial 1 drive fixture to rotate, when fixture rotates with index dial 1
To during close to corresponding station position, lift cylinder 5 is driven by mounting seat 6 and moves on Limit Bearing 8, promotees
Making clamping plate 3 contact with Limit Bearing 8, now chuck body 2 continues motion (until transporting with index dial 1
Move to processing stations), in the process, clamping plate 3 are by the stop of Limit Bearing 8 so that clamping plate 3
Being broken into two with one's hands, clamping plate 3 rotate relative to chuck body 2, and now clamping gap 4 increases, and just can realize
The clamping of valve rod 9 or taking-up；After valve rod 9 clamping, lift cylinder 5 drives Limit Bearing 8 times
Moving so that the backstop relation between Limit Bearing 8 and clamping plate 3 is released from, now clamping plate 3 are at clamping bullet
Homing under the elastic force effect of spring, clamping gap 4 reduces, thus by valve rod 9 Quick-clamped.
The above is only better embodiment of the present utility model, therefore all according to this utility model patent application
The equivalence that structure, feature and principle described in scope is done changes or modifies, and is all included in this utility model
In patent claim.
