Description
Technical field
The present invention relates to field of machining, specifically a kind of thin cylinder port turnery processing internal stay tool.
Technical background
Certain cylinder part is one of important parts of certain solid rocket motor case, finally welds with other parts
Assembling, this solid propellant rocket has strict requirements to the welding quality between cylinder, and the weldering of the port position of cylinder
Connect retaining wall on slope precision welding quality and have considerable influence.
This cylinder part belongs to thin-walled cylindrical workpiece, and cylinder uses rotary press modelling technology, barrel bore Ф 744, wall thickness of cylinder
For 3mm, overall barrel length 1450mm.Design drawing requires that, at cylinder port Vehicle Processing bevel for welding, the gradient of bevel for welding is wanted
Asking is 45 °, and root face is a size of
Traditional thin cylinder port position has two kinds, and a kind of method is by cylinder clamping, clamping by internal stay tool
Mode is manually to regulate the some screws on a kind of annular steel forgings, thus reaches the purpose of clamping centering, the most again
Carry out turnery processing, but this method is it is difficult to ensure that the structure of cylinder end port part realizes the elastic deformation of constant speed, clamping essence
Degree can not reach technological requirement, and in Tutrning Process, cylinder end port part removal amount is uneven, impact welding cut processing essence
Degree.Another kind of method is that pincers worker utilizes angle grinding machine that bevel for welding carries out polishing removal material, and the shortcoming of the method is artificial one-tenth
This is relatively big, and the production cycle is longer.
Summary of the invention
For overcoming clamping precision present in prior art can not reach the deficiency of technological requirement, the present invention proposes one
Cylinder port turnery processing internal stay tool.
The present invention includes mandrel dish, big nut, drive link, push rod, jacking block and slip cap.Wherein: described big nut is set with
On the external screw thread face of the dish post upper end of mandrel dish, slip cap is sleeved on the periphery of dish post lower end of mandrel dish, and makes this
The endoporus of slip cap and described dish post matched in clearance.Two end face bearings are set in bearing groove and the cunning of described big nut
In the bearing groove of dynamic set.Disk cover is sleeved on the external peripheral surface of this big nut, and is fixed on the disk cover erecting bed of described slip cap
Upper surface.Multiple contiguous blocks are separately fixed in the outer rim of connection dish of this slip cap.Multiple push rods are respectively charged into described mandrel
In the jogger hole of plate edge, and one end of each push rod is made to link with each contiguous block respectively；It is that the other end of each push rod is respectively mounted
There is jacking block.The quantity of described contiguous block is identical with the quantity of push rod and jacking block.The inner hole sleeve of handle is contained on big nut.
There is axially projecting dish post at the center of described mandrel dish upper surface, and the external peripheral surface of this dish post is flank.?
There is the annular boss that axis protrudes at the edge of this mandrel dish upper surface, and this annular boss is evenly equipped with multiple jogger hole.
The inner threaded surface of described slip cap coordinates with the external screw thread face of dish post on mandrel dish.Cylindrical in this slip cap upper end
Perimeter surface has the connection dish of radially protruding；Upper surface in the middle part of this connection dish has axially projecting disk cover erecting bed, by this disk cover
The mounting groove that cannelure is end face bearing formed between erecting bed inner surface and this slip cap external peripheral surface.In this slip
Put surface periphery and be evenly equipped with the installing hole of multiple disk cover.
Described big nut inner threaded surface coordinate with the external screw thread face of dish post on mandrel dish.The profile of this big nut upper end
For square or hexagon, it is used for installing the handle of interior cubic or interior six sides；In the middle part of this big nut and following profile is ladder
Shape is circular, and the maximal side that the external diameter at one section of middle part is square more than upper end, the external diameter of lower end and the dish in described slip cap
Lid erecting bed internal diameter is identical.
The inner circumferential surface of described disk cover disk cover coordinates with the external peripheral surface in the middle part of big nut.The limit of this disk cover lower surface
There is axially projecting connection boss at edge, this connection boss is evenly equipped with multiple connecting hole.
One surface of described jacking block is cambered surface, and another surface is plane.Described jacking block plane has " U " of protrusion
Shape auricle, has coaxial installing hole on this auricle.The described curvature of jacking block cambered surface matches with the curvature of work piece inner surface.
Described contiguous block be cross section be the bulk of " L " shape.The termination of this contiguous block vertical plate has for twisting with drive link
The pin shaft hole connect；There is connecting hole the termination of the horizontal plate of this contiguous block, by this connecting hole by the company of this contiguous block Yu slip cap
Flange is connected.
Described drive link has many, and all there is pin shaft hole at the two ends of each drive link.Described push rod has many, one end of each push rod
Having and the pin shaft hole of drive link hinge joint, the other end of each push rod has a jacking block installing hole, and the centrage of described pin shaft hole and institute
The centrage stating jacking block installing hole is mutually perpendicular to.
The present invention disclosure satisfy that the turnery processing of thin cylinder port bevel for welding, and the product indices processed is the fullest
Foot design requirement.In processing, pass through swing handle so that big nut moves down, and promote slip cap by end face bearing
Moving down, drive contiguous block to move down during slip cap moves down, drive link occurs centered by bolt
Turning clockwise, push rod is displaced outwardly, and driving jacking block to be displaced outwardly, until moving to theoretical position, thus realizing cylinder port
Position hold round tensioner, to be processed after, rotating handles, drive jacking block, push rod to contract, unclamp cylinder and take out.
Product to be processed in the present invention is the thin cylinder of rotary press modelling, and the cylinder after rotary press modelling is due to internal stress
The multiple reasons such as release can occur irregular deformation, and the circle of the position to be processed of cylinder end port part is beated more than 5mm, it is difficult to full
The high-precision turnery processing of foot, after using clamping of the present invention, tensioner cylinder, linearity and the circularity of position to be processed cylinder are equal
Less than 0.2mm.
This thin cylinder port position internal stay tool also achieves the clamping of product while tensioner cylinder, after clamping
Cylinder rigidity is obviously improved, and does not occurs trembling, loosens, the situation such as deformation in the course of processing, the bevel for welding of cylinder end port part
Turnery processing result meets design drawing requirement.
Compared with prior art, the invention have the advantages that
1, quality of fit is high, and frock error is little, product uniform force during use.
2, the scope of application is relatively wide, and the position that only need to adjust big nut can be realized as the height of different-diameter cylinder end port part
The clamping of precision.
3, rigidity and the machining accuracy of thin cylinder port position can be effectively improved, solve thin cylinder port part
The technical barrier of position turning.
4, the present invention is aiming at the processing difficulties of the said goods, by a kind of thin cylinder port turnery processing internal stay work
Dress is arranged on inside spinning cylinder port, it is achieved the school shape of spinning cylinder, holds round, ensure clamping, machining accuracy, reduces artificial behaviour
Make intensity, improve production efficiency.
