Description
【Technical field】
The present invention relates to a kind of technical field of mixed-flow stator auxiliary processing device, particularly a kind of mixed-flow stator adds
The technical field of work counter weight device.
【Background technology】
At present, Francis turbine is one of widely used hydraulic turbine pattern in countries in the world, its compact conformation, efficiency
It is higher, adapt to very wide head scope.Francis turbine is main by spiral case, top cover, seat ring, draft tube, base ring, control
Ring, stator, main shaft, runner etc..Wherein stator is the part for being used in Francis turbine adjust flow.
Because the low microcephaly's stator design structure of mixed-flow is that blade face is roomy, two end axles are slender axles, and airfoil surface is laid particular stress on
It is larger, in turning and grinding process, larger winding degree can be produced, typically by reducing on airfoil surface plus bascule
The winding degree produced in turning and grinding process, of the prior art, the weight of bascule can not be carried out according to the need for counterweight
Regulation, and it is fixed inconvenient.
【The content of the invention】
The purpose of the present invention is exactly to solve the problems of the prior art, proposes a kind of mixed-flow stator processing with refitting
Put, weight adjustment can be carried out as needed, is fixed conveniently.
To achieve the above object, the present invention proposes a kind of mixed-flow stator processing counter weight device, including at least one U
Shape bolt, grip slipper and balance weight body, the front end of the grip slipper are provided with the V-shaped groove being engaged with the Balance weight end of the blade of stator,
The upper and lower ends of the grip slipper are equipped with connection shirt rim and groove, and the connection shirt rim is located at the front of groove, the U-shaped spiral shell
Two straight-bars of bolt are each passed through two connection shirt rims, and two straight-bars of the U bolt are connecting the rear side of shirt rim provided with tight
Gu nut, the front end of the balance weight body is provided with two connectors up and down, and the leading inside of the connector is equipped with and groove phase
The projection of cooperation.
Preferably, being equipped with the fastening bolt of threaded connection on a wherein connector, the connector passes through tight
Fixing bolt is fixedly connected with grip slipper.
Preferably, the inwall of the V-shaped groove is covered with one layer of plastic protection pad.
Preferably, the upper end of the grip slipper is provided with lifting bolt.
Preferably, the curved portions of the U bolt are arranged with plastic sheath.
Beneficial effects of the present invention：The present invention is enclosed in the Balance weight end of the blade of stator in use, slinging grip slipper, then
It is fixed on by U bolt on the blade of stator, balance weight body is then selected as needed, balance weight body is fixed on grip slipper,
Grip slipper is in assembling, it is ensured that raised corresponding with the end of groove, then promotes grip slipper, protrudes out into groove, treats counterweight
Body fastens fastening bolt, compared with prior art, weight adjustment can be carried out as needed to after certain position, fixed
It is convenient.
The feature and advantage of the present invention will be described in detail by embodiment combination accompanying drawing.
【Brief description of the drawings】
Fig. 1 is a kind of structural representation of mixed-flow stator processing counter weight device of the invention.
