Abstract
The utility model discloses a kind of ball valve clamp for machining, including scroll chuck and tailstock, umbrella-shaped lathe center is installed on tailstock, axis alignment between umbrella-shaped lathe center and scroll chuck, there are multiple radially movable telescopic claws on the end face of scroll chuck, the plurality of telescopic claw circumferential arrangement at regular intervals, fan-shaped clamp body is installed on telescopic claw, the fan-shaped clamp body includes sector disk, sector disk extends outward the jig arm of fan shape close to the position in axle center, multiple jig arm circumferential arrangements form the telescopic clamping bar of external diameter, the tip of umbrella-shaped lathe center is supported in the gap between multiple jig arm end faces.This structure of the present utility model, the fast positioning of workpiece can be completed, realized in the laser cladding process of ball valve sealing face, no comprehensive processing in dead angle, and process is reliable and stable.
Description
Technical field
It the utility model is related to a kind of clamp for machining of ball valve in laser melting coating.
Background technology
At present, obtained in terms of the wear-resisting corrosive nature of valve sealing face is improved using laser melting and coating technique and extensively should
With.But ball valve is a kind of very big Special valve of dosage, is characterized in, there is axis hole on ball valve, the opening both ends of axis hole with
And sphere has the demand of wearability, this special surface is when realizing laser melting coating, if entering luggage by fast positioning
Folder, it is to determine the key point that can laser cladding process be smoothed out, the method most generally used in the prior art is by ball
Valve is fixed by scroll chuck.After being fixed on due to ball valve workpiece by axis hole on scroll chuck, the axis hole end face of ball valve
It is too small with the spacing of scroll chuck so that laser is difficult to be shining into the end face and axis hole of ball valve, and therefore, laser melting coating can not
The dead angle laser melting coating of sphere is realized, this directly influences the yield rate of ball valve laser melting coating.
The content of the invention
To solve the above problems, the purpose of this utility model be to provide a kind of workpiece positioning reliably can be comprehensive to ball valve
Carry out the ball valve laser melting coating clamp for machining of laser melting coating.
To achieve the above object, the utility model provides following technical scheme：A kind of ball valve laser melting coating clamp for machining,
Including scroll chuck and tailstock, push rod, the axis between the push rod and the scroll chuck are installed on described tailstock
Align, there are multiple radially movable telescopic claw, the plurality of telescopic claws to justify at regular intervals on the end face of the scroll chuck
Week arrangement, it is characterised in that fan-shaped clamp body is provided with described telescopic claw, the fan-shaped clamp body includes sector disk, institute
State sector disk and extend outward the jig arm that section is fan shape close to the position in axle center, multiple jig arm circumferential arrangements form outer
The telescopic clamping bar in footpath.
The push rod is umbrella-shaped lathe center, and the umbrella shape tip can be supported in the gap between the multiple jig arm end face.
This structure of the present utility model, the axis hole of ball valve workpiece to be processed are socketed in multiple jig arm circumferential arrangements and formed outside
On the telescopic clamping bar in footpath, by adjusting the outside Slideslip of telescopic claw, the clamping to ball valve workpiece axis hole, while umbrella shape top are realized
The tip of point is supported in the gap between the multiple jig arm end face so that workpiece positioning is reliable, and the axis hole end face of ball valve
There is longer distance with scroll chuck, be easy to laser by carrying out cladding, can carry out laser melting coating comprehensive to ball valve, greatly
Improve yield rate of the ball valve in laser melting coating.
Brief description of the drawings
The utility model is further described with reference to the accompanying drawings and detailed description.
Fig. 1 is the stereogram of the utility model embodiment.
Embodiment
As shown in figure 1, this ball valve clamp for machining, including scroll chuck 1 and tailstock 2, push rod is installed on tailstock 2, should
Push rod is umbrella-shaped lathe center 3, the axis alignment between umbrella-shaped lathe center 3 and scroll chuck 1, has three on the end face of scroll chuck 1
Individual radially movable telescopic claw 11, three circumference of telescopic claw 11, which are divided equally, to be arranged, and fan-shaped fixture is provided with telescopic claw 11
Body 5, the fan-shaped clamp body 5 include sector disk 51, and sector disk 51 extends outward section as fan shape close to the position in axle center
Jig arm 52, three circumferential arrangements of jig arm 52 form the telescopic clamping bar 6 of external diameter, and the tip of umbrella-shaped lathe center 3 is supported into multiple jig arm 52
In gap between end face, sector disk 51 and jig arm 52 are integrated setting.
This structure of the present utility model, the axis hole of ball valve workpiece 7 to be processed are socketed in multiple circumferential arrangement shapes of jig arm 52
Into on the telescopic clamping bar 6 of external diameter, by adjusting 11 outside Slideslip of telescopic claw, the clamping to the axis hole of ball valve workpiece 7 is realized, by
There is certain length in clamping bar 6, after ball valve workpiece 7 is fixed on clamping bar 6, prevents the outermost end of clamping bar 6 from shrinking, cause
Ball valve fixation is not tight, therefore, the tip of umbrella-shaped lathe center 3 is supported in the gap between multiple end faces of jig arm 52, with holding jig
The good rigidity of body.Strut clamping bar 6 so that ball valve workpiece is tightly positioned on clamping bar 6, and ball valve workpiece 7 is due to being fixed on folder
On bar 6, thus, there is larger spacing, now, when laser melting coating is processed, laser is just between ball valve workpiece 7 and scroll chuck
The end face and axis hole end of ball valve can be irradiated to, realizes ball valve without dead angle laser melting coating, the matter of guarantee ball valve laser melting coating
Amount.
