Abstract
The utility model relates to a gear hobbing die capable of changing a clamping sleeve rapidly. The gear hobbing die comprises a die seat and a die body which are connected axially, and a tubular rapid-changing clamping sleeve. A lower boss of one end of the rapid-changing clamping sleeve is provided with a radial U-shaped positioning groove, the other end of the rapid-changing clamping sleeve is provided with two axial grooves formed axially and uniformly so as to form two clamping sleeve sheets on the upper portion of the rapid-changing clamping sleeve, and the two axial grooves of the rapid-changing clamping sleeve are provided with clamping bolts used for tightening or loosening the two clamping sleeve sheets; the end face of the upper step of the die body is provided with a downward-concave round groove provided with anti-rotating pin; the lower boss of the rapid-changing clamping sleeve is located in the round groove of the upper step of the die body in a matched manner, and the anti-rotating pin is located in the U-shaped positioning groove in the lower boss of the rapid-changing clamping sleeve. When the gear hobbing die is used for machining long shaft parts in different specifications, the entire die change is omitted, producing efficiency is improved, and work intensity of die changing is reduced; the number of dies is decreased, and manufacture cost is reduced.
Description
Technical field
The utility model belongs to equipment Technology field, is specifically related to a kind of gear hobbing mould for the processing of longaxones parts external splines.
Background technology
At the gear-hobbing machine for the processing of longaxones parts external splines, longaxones parts adopts major axis vertical direction to place conventionally, adopts lower end gear hobbing mould location fixing, upper end tail stock for machine tool thimble location.Because major axis series products is more, a lot of long axis workpiece external splines processing is without particular manufacturing craft, and the actual cylindrical that adopts lower end scroll chuck holding workpiece, clamps by flat circle end face location, and upper end lathe center holds out against.The advantage of which is: can realize workpiece and locate fast, clamp, change product also more convenient, as long as regulate the size of scroll chuck.Shortcoming is: grab chuck precision impact due to three, easily cause external splines center and bearing center not to overlap, affect product external splines and each grade of cylindrical concentricity quality.Existing part major axis external splines processing, adopts gear hobbing mould in lower end to fix, and because thimble is placed in mould, die ejector pin can not be realized replacing, and gear hobbing mould is all the corresponding a kind of mould of a kind of product.Existing gear hobbing model point is: accurate positioning, and realize long axis workpiece two ends centre bore and adopt two thimble location, guarantee external splines and each grade of cylindrical concentricity of major axis, improve the quality of products.Shortcoming is: number of molds is too much, due to longaxones parts specification disunity, and the corresponding a kind of mould of a kind of product, die manufacturing cost is haggled over height.In production, number of molds is too much, is not easy to management maintenance.Change product more difficult, the die change time is also longer, needs the Correction Die centre of gyration again after replacing, the waste plenty of time.
Utility model content
In order to improve the versatility for the gear hobbing mould of longaxones parts external splines processing, the utility model provides a kind of gear hobbing mould of fast changeable chuck.
Concrete Structure Improvement Design scheme is as follows: the gear hobbing mould of fast changeable chuck comprises axial die holder and the mould body of connecting; Described die holder is flange-like, and the tube shape bulge that the die holder of flange hole bottom is connecting is provided with thimble in tube shape bulge; Described mould is as the annulus with upper and lower two stage steps, the diameter of subordinate's step is greater than the diameter of higher level's step, subordinate's step of mould body is connecting the die holder on flange hole top, improvement is: the quick change chuck that also comprises tubulose, the lower end of described quick change chuck is provided with the radially lower convex platform of abduction, on described lower convex platform, offer a U-shaped locating slot radially, the outward opening of described U-shaped locating slot; The top of quick change chuck is uniform vertically offers two axial grooves, makes the top of quick change chuck form two chuck sheets, on the quick change chuck at two axial groove places, is respectively equipped with the fishbolt that two chuck sheets are tightened up or unclamped; The end face of higher level's step of described mould body is provided with to recessed circular groove, is provided with stop pin in circular groove; The lower convex platform of quick change chuck coordinates the circular groove of the higher level's step that is positioned at mould body, and described stop pin is positioned at the U-shaped locating slot on the lower convex platform of quick change chuck; The other end of described quick change chuck is provided with the radially convex platform of abduction, is respectively equipped with to recessed groove on the convex platform of every axial groove both sides, two chuck sheets is tightened up or the fishbolt that unclamps is positioned at axial groove grooves on two sides.
The utility model is compared with prior art products has advantages of following aspect:
1. by setting up quick change chuck, during the longaxones parts of processing different size, when longaxones parts length is in the thimble scope of application, do not need to change whole mould, only according to part external diameter, change quick change chuck, reduced mould replacing time, improved production efficiency;
2. use this product, reduce on the one hand die change labour intensity; Reduce on the other hand number of molds, reduced manufacturing cost.
