Description
Technical field
The invention belongs to a kind of chucking device when processing part, be specifically related to a kind of thin-walled major diameter zero carrying location
Part chucking device.
Background technology
The thin-walled major diameter External Shape used in some commercial production is bowl-shape, and oral area is relatively thin, its required precision height,
Processing technique requires strict.
Owing to processed diameter of part is big, wall is thin, general diameter is about 0.5mm more than 130mm, thickness, and part is same
Axle degree, circularity, wall unevenness evenness require relatively strict, so being easy to produce machining deformation in the course of processing, affect part
Size and form and position tolerance, difficulty of processing is bigger.
Summary of the invention
The present invention proposes to overcome shortcoming present in prior art, its objective is to provide one to carry location
Thin-walled major diameter part chucking device.
The technical scheme is that
A kind of thin-walled major diameter part chucking device carrying location, including positioning core axle and being arranged on positioning core axle
Instrument claw assembly, positioning core axle is connected with machine tool chief axis by through hole, and instrument claw assembly is by shoulder hole and the three of machine tool chief axis
Dog chuck connects, in the bowl-type groove that bowl-type workpiece is arranged on positioning core axle, inner circle and the instrument pawl group of its lower end cylinder part
The cylindrical on part top coordinates.Described positioning core axle is column type, and upper end forms upper flange, forms bowl-type groove on upper flange, under
End is formed for the flange fixing with machine tool chief axis, and described instrument claw assembly is the circular arc type work the most identical by three shape sizes
Tool pawl composition, the lower end of instrument pawl forms lower flange.
The circumference of described flange forms three uniform breach, in the cylinder bottom of positioning core axle corresponding to breach
Also three uniform breach are formed.
Described each instrument pawl is circumferentially formed two ladders for being connected with the scroll chuck of machine tool chief axis
Hole.
The invention has the beneficial effects as follows:
Present configuration is simple and convenient to operate, and part will not deform in the course of processing, dimensionally stable, efficiency height,
Low cost, it is adaptable to dimension precision requirement is compared with Geometrical Tolerance Principle such as high, diameter big, eccentricity, axiality, concentricitys relatively
Strict various materials major diameter, the processing and forming of thin-walled parts, it is adaptable to batch machining.

Detailed description of the invention
Below, the thin-walled major diameter part chucking device that the present invention carries location in conjunction with the accompanying drawings and embodiments is carried out in detail
Illustrate:
As shown in Figure 1, 2, a kind of thin-walled major diameter part chucking device carrying location, including positioning core axle 1 and installation
Instrument claw assembly 2 on positioning core axle 1, positioning core axle 1 is connected with machine tool chief axis (not shown) by through hole 5, instrument pawl group
Part 2 is connected with the scroll chuck of machine tool chief axis (not shown) by shoulder hole 12.Bowl-type workpiece is arranged on the bowl on positioning core axle 1
Shape groove 6 is interior, the inner circle of its lower end cylinder part coordinates with the cylindrical on instrument claw assembly 2 top.
As shown in Figure 3,4, described positioning core axle 1 is in column type, and upper end forms upper flange 3, forms bowl-type on upper flange 3
Groove 6, lower end is formed for the flange 4 fixing with machine tool chief axis, forms three uniform through holes 5 on the circumference of flange 4,
Also form three uniform breach 9 on the circumference of flange 4, also form three in the cylinder bottom of the positioning core axle 1 of breach 9 correspondence
Uniform breach 9；Being centrally formed blind hole 7 at upper flange 3, the lower center at positioning core axle 1 forms lower blind hole 8.Fixed
Formed on the cylinder bottom of mandrel 1, position and flange 4 breach 9 be in order to when positioning core axle 1 is connected with machine tool chief axis to lathe master
The scroll chuck of axle leaves space.
As shown in Figure 5,6, described instrument claw assembly 2 is made up of the circular arc type instrument pawl 10 that three shape sizes are the most identical
, the lower end of instrument pawl 10 forms lower flange 11, is circumferentially formed for the three-jaw with machine tool chief axis on each instrument pawl 10
Two shoulder holes 12 that chuck connects.
The effect of positioning core axle 1 is to need the workpiece 13 of processing to position, and makes the workpiece 13 will not be by instrument pawl 10 footpath
Producing movement to the impact of expansion contractile motion, instrument pawl 10 is then again by swollen for workpiece 13 after workpiece 13 is positioned
Tightly, it is simple to be processed.
Positioning core axle 1 is arranged on the main shaft of lathe, is fixed, and instrument claw assembly 2 is by screw and main shaft
Scroll chuck connects, and can complete clamping workpiece along with the motion of claw.
Part adds man-hour, first positioning core axle 1 and instrument claw assembly 2 is installed (as shown in Figure 1), the most respectively will be fixed
Position mandrel 1 is connected with machine tool chief axis, is connected with the scroll chuck of machine tool chief axis by instrument claw assembly 2, by locating core on lathe
The end face of axle 1 is processed into the bowl-type groove 6 identical with the bottom shape of workpiece 13；The Excircle machining on instrument claw assembly 2 top is become
The size matched with the inner circle of the lower end cylinder part of workpiece 13.Finally workpiece 13 hand pressure is contained in bowl-type groove 6, workpiece
The lower end cylinder part of 13 coordinates with the cylindrical with instrument claw assembly 2 top, then drives instrument pawl 10 to do footpath by foot pedal
To extensional motion by workpiece 13 swelling (as shown in Figure 2), then workpiece is carried out postorder processing.
