Technical field
The utility model belongs to chucking device during a kind of processing parts, is specifically related to a kind of thin-walled major diameter part chucking device carrying location.
Background technology
The thin-walled major diameter External Shape used in some industrial production is bowl-shape, and oral area is thinner, and its required precision is high, processing technology requires strict.
Because processed diameter of part is large, wall is thin, general diameter is greater than 130mm, thickness is about 0.5mm, and part axiality, circularity, wall unevenness evenness require comparatively strict, 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 utility model proposes to overcome the shortcoming existed in prior art, its objective is and provides a kind of thin-walled major diameter part chucking device carrying location.
The technical solution of the utility model is:
A kind of thin-walled major diameter part chucking device carrying 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 in the bowl-type groove of bowl-type trade union college on positioning core axle, the inner circle of its lower end cylinder part coordinates with the cylindrical on instrument claw assembly top.Described positioning core axle is column type, upper end forms upper flange, and upper flange is formed bowl-type groove, and lower end is formed and is used for the flange fixing with machine tool chief axis, described instrument claw assembly is made up of the circular arc type instrument pawl that three shape sizes are all identical, and the lower end of instrument pawl forms lower flange.
Circumferentially form three uniform breach at described flange, also form three uniform breach in the cylindrical shell bottom of positioning core axle corresponding to breach.
Described each instrument pawl is circumferentially formed two shoulder holes for being connected with the scroll chuck of machine tool chief axis.
The beneficial effects of the utility model are:
The utility model structure is simple, 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, thin-walled parts processing and forming, be applicable to batch machining.

Detailed description of the invention
Below, in conjunction with the accompanying drawings and embodiments a kind of thin-walled major diameter part chucking device carrying location of the utility model is described in detail:
As shown in Figure 1, 2, a kind of thin-walled major diameter part chucking device carrying location, the instrument claw assembly 2 comprising positioning core axle 1 and be arranged 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.In the bowl-type groove 6 of bowl-type trade union college on positioning core axle 1, 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, upper end forms upper flange 3, upper flange 3 is formed bowl-type groove 6, lower end is formed and is used for the flange 4 fixing with machine tool chief axis, circumferentially form three uniform through holes 5 at flange 4, circumferentially also form three uniform breach 9 at flange 4, also form three uniform breach 9 in the cylindrical shell bottom of the positioning core axle 1 of breach 9 correspondence; In upper flange 3, be formed centrally blind hole 7, form lower blind hole 8 at the lower center of positioning core axle 1.It is in order to the scroll chuck when positioning core axle 1 is connected with machine tool chief axis to machine tool chief axis leaves space that the cylindrical shell bottom of positioning core axle 1 with flange 4 are formed breach 9.
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 all identical, the lower end of instrument pawl 10 forms lower flange 11, and each instrument pawl 10 is circumferentially formed two shoulder holes 12 for being connected with the scroll chuck of machine tool chief axis.
The effect of positioning core axle 1 to need the workpiece 13 of processing to position, make workpiece 13 can not produce movement by the impact of instrument pawl 10 radial dilatation contractile motion, instrument pawl 10 be then after workpiece 13 is had good positioning again by workpiece 13 swelling, 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 come clamping workpiece along with the motion of claw.
Part adds man-hour, first positioning core axle 1 and instrument claw assembly 2 are installed (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 by lathe; By the size that the Excircle machining on instrument claw assembly 2 top becomes to match with the inner circle of the lower end cylinder part of workpiece 13.Finally be contained in bowl-type groove 6 by workpiece 13 hand, the lower end cylinder part of workpiece 13 coordinates with the cylindrical on instrument claw assembly 2 top, then does radial dilatation motion by workpiece 13 swelling (as shown in Figure 2) by foot pedal driven tool pawl 10.Again postorder processing is carried out to workpiece.
