Abstract
The utility model discloses a gear external spline hobbing clamp which is characterized by comprising a base (1), a mandrel and a check ring (3), wherein the base (1) is of a convex type, the mandrel is arranged in a center hole of the base (1), the mandrel is composed of a polished rod section (2a), a spline section (2b) and a threaded rod section (2c), the polished rod section (2a) is located on the lower portion of the mandrel and is inserted into the center hole of the base (1), the upper end of the polished rod section (2a) extends out of the center hole of the base (1), the spline section (2b) is located between the threaded rod section (2c) and the polished rod section (2a), an external spline is arranged on the spline section (2b), and the lower portion of the mandrel is sleeved with the check ring (3). The gear external spline hobbing clamp is reasonable in design, simple in structure, easy to apply, convenient to use and operate, and high in measuring precision.
Description
Technical field
The utility model relates to a kind of fixture, particularly a kind of gear external splines gear-hobbing clamp.
Background technology
Gear hobbing is the basic operation of Gear Processing, adopts to roll to shave processes gear, and gear hobbing precision plays a decisive role to the final precision of gear, generally adopts at present Digit Control Machine Tool machining gears, effectively raises machining accuracy and the working (machining) efficiency of gear.But current numerical control gear-hobbing clamp complex structure, required precision be high, involve great expense, handling are inconvenient.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of gear external splines gear-hobbing clamp simple in structure.
The technical solution of the utility model is as follows: a kind of gear external splines gear-hobbing clamp, it is characterized in that: comprise base (1), mandrel and back-up ring (3), described base (1) is convex, in the centre bore of base (1), be provided with mandrel, described mandrel is by polished rod section (2a), spline segment (2b) and spiro rod section (2c) form, described polished rod section (2a) is positioned at the bottom of mandrel, in the centre bore of described polished rod section (2a) inserted base (1), and outside the centre bore of the upper end protuberate basic unit (1) of polished rod section (2a), described spline segment (2b) is positioned between spiro rod section (2c) and polished rod section (2a), described spline segment (2b) is provided with external splines, the bottom cover of described mandrel has back-up ring (3).
Adopt technique scheme, base is bolted on gear-hobbing machine, for gear inner surface, be provided with the gear of internal spline, spline segment plays the effect of guide-localization, back-up ring plays the effect of avoiding gear to fall into polished rod section, avoids the too many rear field of conjugate action to be mingled with iron filings or to cause gap and the error that assembling exists.Load onto after gear, by screw rod, coordinate nut to lock.Simple in structure, precision is high.When gear for different size, can change the back-up ring of different size.
In technique scheme, the height of described back-up ring (3) is greater than the length of the outer polished rod section (2a) of protuberate basic unit (1).The model of adjustable back-up ring, so that the processing of the gear of the another kind of gear of the quantity of adaptation clamped one time product of the same race or the internal spline of same specification.
As preferably: the diameter of described spiro rod section (2c) is less than the path of spline segment (2b).
As preferably: the upper cover of described spiro rod section (2c) has pressing plate (4).
As preferably: described pressing plate (4) is provided with the breach (4a) communicating with the centre bore of pressing plate (4).
Beneficial effect: the utility model is reasonable in design, simple in structure, enforcement is easy, and easy to use, easy to operate, measuring accuracy is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of pressing plate of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1-2, gear external splines gear-hobbing clamp of the present utility model mainly contains base 1, and the parts such as back-up ring 3 and mandrel form.Described base 1 forms convex by bottom mount pad and top locating dowel, described bottom mount pad is provided with bolt hole, in the centre bore of base 1, be provided with mandrel, described mandrel is comprised of polished rod section 2a, spline segment 2b and spiro rod section 2c, described polished rod section 2a is positioned at the bottom of mandrel, in the centre bore of the bottom inserted base 1 of described polished rod section 2a, and outside the centre bore of its upper end protuberate basic unit 1, described spline segment 2b is between spiro rod section 2c and polished rod section 2a, described spline segment 2b is provided with external splines, and the diameter of described spiro rod section 2c is less than the path of spline segment 2b.The bottom cover of described mandrel has back-up ring 3, the height of described back-up ring 3 to be greater than the length of the polished rod section 2a outside protuberate basic unit 1.
During use, gear ring is enclosed within to spline segment 2b upper, the lower end of gear ring contacts with back-up ring 3, and the upper end of gear ring locks by the nut on spiro rod section 2c.On described spiro rod section 2c, also cover has pressing plate 4, and described pressing plate 4 is provided with the breach 4a communicating with centre bore.
