Description
Technical field
The present invention relates to a kind of cutting frock clamp of the outer eaves of annular, more particularly to a kind of spherical cover body to thin-walled
The outer eaves of annular clamp the cutting frock of cutting.
Background technology
The spherical cover body of the relatively thin outer eaves of band annular of wall thickness, usually forms spherical crown shape with metal sheet after punching press
Cover body, the outer eaves of annular of a loop can be formed in the rounded outer edge of ball corona shield, due in punching press spherical crown shape cover
During body, its edge makes the outside dimension of the outer eaves of annular that is formed after punching press inconsistent, no there occurs outside irregular extension
Meet Product Assembly requirement, it is necessary to cut eaves outside annular, the outside dimension of the outer eaves of annular is reached consistent.It is general to cut pin
Carried out on lathe, in turning, by the medial surface apical grafting of ball corona shield in the lathe spindle side consistent with medial surface
On fixture, the lateral surface of ball corona shield is crimped on the tail stock side fixture consistent with lateral surface, on tail stock
Top apical grafting lathe spindle rotation, drives whole workpiece to be machined and folder on the lateral surface central point of tail stock side fixture
Tool rotation, so as to complete the cutting of the outer eaves of annular of the ring-type in the rounded outer edge to ball corona shield.But when what is be processed
Spherical cover body is relatively large in diameter, and need carry out batch machining when, the tail stock side fixture used in this processing method
Diameter can also increase therewith, cause tail stock side fixture big and heavy, loading and unloading clamp is inconvenient during batch machining, and work is by force
Degree is big；Top positioning on the lateral surface central point of the tail stock side fixture of top institute's apical grafting particularly on tail stock
Hole, top positioning hole can be easily caused due to clamping abrasion, and the downward dragging of bulky tail stock side fixture repeatedly
Skew and damage, after making the top apical grafting workpiece on tail stock, directly contribute workpiece centre axis and glance off, cause annular
Outer eaves cutting is eccentric, produces waste product；In addition, in pin method is cut in this clamping, the top and tail stock side on tail stock
The apical grafting of fixture is to realize that sound coordinates by linking work at selected spots with that in entire areas, and when workpiece and fixture are relatively large in diameter, the sound for putting face is matched somebody with somebody
There is in working angles the problem of stability is poor, and clamped workpiece easily trembles in credit union, have influence on the machining accuracy of workpiece,
Workpiece case accident is also occurred that when serious.
The content of the invention
The invention provides a kind of cutting frock of the outer eaves of annular of the spherical cover body of thin-walled, solve high-volume and process greatly
Top of the spherical cover body of thin-walled of size in the annular outer eaves of cutting on the lateral surface central point of existing tail stock side fixture
The technical problem that sharp positioning hole easily shifts and damaged.
The present general inventive concept is：In workpiece rotary cutting pin, by the lathe centre and work after the piece-holder of routine
The quiet dynamic point face apical grafting of part fixture coordinates, and changes into quiet dynamic face face and coordinates, specifically the tail stock side in clamping workpiece
A pair of radial bearings are installed in the center tube inner chamber of fixture, lathe centre are replaced with radial bearing central shaft, in radial bearing
Outer ring on be fixedly mounted for clamping workpiece tail stock side fixture, pass through the motionless and radial bearing of radial bearing central shaft
Outer ring rotation, realize quiet dynamic face face and coordinate, and tail stock side folder is fixedly mounted on the outer ring for passing through radial bearing
The face contact of tool, realizes the reliable retention to workpiece, overcomes the wobble problem of large-size workpiece in processing.In addition, to two
The hollow out design of holder, also significantly reduce the weight of fixture.
The present invention is that solve above technical problem by the following technical programs：
A kind of cutting frock of the outer eaves of annular of spherical cover body of thin-walled, including the positioning of lathe spindle Three-jaw fixture, tail stock
Taper hole and the spherical cover body of thin-walled, are provided with eaves outside ring-type in the outer rim of the spherical cover body of thin-walled, in the claw clip of lathe spindle three
Support fixture central shaft is clamped with tool, the spherical crown shape support of lathe spindle side is fixedly connected with the outer end of support fixture central shaft
Fixture, the spherical cover body of thin-walled is provided with the spherical crown shape support fixture of lathe spindle side, is set on the spherical cover body of thin-walled
There is tail stock side fixture ring compression circle, tail stock side is provided with the center of tail stock side fixture ring compression circle
Clamp central cylinder, it has been positioned apart from putting between tail stock side fixture ring compression circle and tail stock side clamp central cylinder
Shape fixture rib is penetrated, radial bearing is provided with the lumen orifice of tail stock side clamp central cylinder, is set in radial bearing
There is radial bearing central shaft, the outer end of radial bearing central shaft is provided in tail stock positioning taper hole.
Plate washer on the inside of radial bearing is provided with the interior end side surface of tail stock side clamp central cylinder, in radial bearing
Side plate washer center is provided with band step through-hole, and centripetal stretching screw, centripetal stretching screw are movably set with band step through-hole
Inner face through after with step through-hole with radial bearing central shaft is fixed together；In the inner side of radial fixture rib
Arcwall face is provided with, radial fixture rib is that the arcwall face set by inner side crimps with the lateral surface of the spherical cover body of thin-walled
Together.
Lathe spindle side spherical crown shape support fixture is by annular brace circle, support fixture central shaft and cross supporting rib
Composition, cross supporting rib is connected between annular brace circle and central shaft, the lateral surface of cross supporting rib is
Arcwall face, cross supporting rib is by its arc external side together with the medial surface apical grafting of the spherical cover body of thin-walled.
Clamping device of the present invention is in light weight, and execute-in-place labor intensity is small, particularly realizes the quiet dynamic face face of clamping
Coordinate, the use of radial bearing ensure that in batch cutting workpiece, can keep not glancing off for central axis all the time, carry significantly
The high precision of work pieces process, solves the reliable grip of large scale workpieces processing rotation processing, effectively overcomes in processing and quiver
The defects of dynamic.
