Technical field
Chucking device while the invention belongs to a kind of processing parts, is specifically related to a kind of thin-walled major diameter part chucking device that carries location.
Background technology
The thin-walled major diameter External Shape using in some industrial production is bowl-shape, and oral area is thinner, and its required precision is high, processing technology requires strict.
Because institute's processing parts diameter is large, wall is thin, general diameter is greater than 130mm, thickness is 0.5mm left and right, and that part axiality, circularity, wall unevenness evenness require is stricter, so be easy to produce machining deformation in process, affect accessory size and form and position tolerance, difficulty of processing is larger.
Summary of the invention
The present invention proposes in order to overcome the shortcoming existing in prior art, its objective is a kind of thin-walled major diameter part chucking device that carries location is provided.
Technical scheme of the present invention is:
A kind of thin-walled major diameter part chucking device that carries location, comprise positioning core axle and be arranged on the instrument claw assembly on positioning core axle, positioning core axle is connected with machine tool chief axis by through hole, instrument claw assembly is connected with the scroll chuck of machine tool chief axis by shoulder hole, and bowl-type workpiece is arranged in the bowl-type groove on positioning core axle, the inner circle of its lower end cylindrical portions coordinates with the cylindrical on instrument claw assembly top.Described positioning core axle is column type, and upper end forms upper flange, forms bowl-type groove on upper flange, described instrument claw assembly by three shape sizes all identical circular arc type instrument pawl forms, the lower end formation lower flange of instrument pawl.
On the circumference of described flange, form three uniform breach, in the cylindrical shell bottom of positioning core axle corresponding to breach, also form three uniform breach.
On each described instrument pawl, be circumferentially formed two shoulder holes for being connected with the scroll chuck of machine tool chief axis.
The invention has the beneficial effects as follows:
The present invention is simple in structure, easy to operate, part can not deform in process, dimensionally stable, efficiency is high, cost is low, be applicable to the stricter various materials of the Geometrical Tolerance Principle such as dimension precision requirement is large compared with high, diameter, eccentricity, axiality, concentricity major diameter, the processing and forming of thin-walled parts, be applicable to batch machining.

The specific embodiment
Below, the thin-walled major diameter part chucking device that in conjunction with the accompanying drawings and embodiments the present invention is carried to location is elaborated:
As shown in Figure 1, 2, a kind of thin-walled major diameter part chucking device that carries location, comprise positioning core axle 1 and be arranged on the 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, and instrument claw assembly 2 is connected with the scroll chuck (not shown) of machine tool chief axis by shoulder hole 12.Bowl-type workpiece is arranged in the bowl-type groove 6 on positioning core axle 1, the inner circle of its lower end cylindrical portions coordinates with the cylindrical on instrument claw assembly 2 tops.
As shown in Figure 3,4, described positioning core axle 1 is column type, upper end forms upper flange 3, on upper flange 3, form bowl-type groove 6, lower end is formed for the flange fixing with machine tool chief axis 4, on the circumference of flange 4, form three uniform through holes 5, on the circumference of flange 4, also form three uniform breach 9, in the cylindrical shell bottom of the positioning core axle 1 of breach 9 correspondences, also form three uniform breach 9; In upper flange 3, be formed centrally blind hole 7, in the lower end of positioning core axle 1, be formed centrally lower blind hole 8.Cylindrical shell bottom at positioning core axle 1 is to leave space for the scroll chuck to machine tool chief axis when positioning core axle 1 is connected with machine tool chief axis with forming breach 9 on flange 4.
As shown in Figure 5,6, described instrument claw assembly 2 by three shape sizes all identical circular arc type instrument pawl 10 form, the lower end of instrument pawl 10 forms lower flange 11, is circumferentially formed two shoulder holes 12 for being connected with the scroll chuck of machine tool chief axis on each instrument pawl 10.
The effect of positioning core axle 1 is that the workpiece 13 of needs processing is positioned, make workpiece 13 can not be subject to the impact of instrument pawl 10 radial dilatation contractile motions and produce movement, instrument pawl 10 be after workpiece 13 is positioned again by workpiece 13 swellings, be convenient to process.
Positioning core axle 1 is arranged on the main shaft of lathe, is fixed, and instrument claw assembly 2 is connected with the scroll chuck of main shaft by screw, can complete clamping workpiece along with the motion of claw.
Part adds man-hour, first positioning core axle 1 and instrument claw assembly 2 are installed to (as shown in Figure 1), then respectively positioning core axle 1 is connected with machine tool chief axis, instrument claw assembly 2 is connected with the scroll chuck of machine tool chief axis, the end face of positioning core axle 1 is processed into the bowl-type groove 6 identical with the bottom shape of workpiece 13 on lathe; The size that the Excircle machining one-tenth on instrument claw assembly 2 tops is matched with the inner circle of the lower end cylindrical portions of workpiece 13.Finally workpiece 13 use hands are contained in bowl-type groove 6, the lower end cylindrical portions of workpiece 13 with coordinate with the cylindrical on instrument claw assembly 2 tops, by foot pedal driven tool pawl 10, do radial dilatation motion by workpiece 13 swellings (as shown in Figure 2) again, then workpiece is carried out to postorder processing.
