Abstract
The utility model discloses a broaching tool of cone hole internal keyways, wherein the broaching tool comprises a locating sleeve and a guide sleeve. An axial locating end face and an outer cylindrical locating face are arranged on the locating sleeve. The rear section of the guide sleeve is arranged in the locating sleeve. A limiting counter bore is formed at the front end of an inner hole of the locating sleeve. A locating shaft shoulder which is matched with the limiting counter bore is arranged in the middle of the guide sleeve. A cone section which is matched with a cone hole of a workpiece is arranged at the front section of the guide sleeve. The axis of the cone section is crossed with the axis of the outer cylindrical locating face of the locating sleeve, and the included angle between the two axes is equal to the included angle between a bus of the cone hole of the workpiece and the axis of the cone hole. A broach limiting groove which is communicated along the axis direction of the guide sleeve is formed in the guide sleeve. According to the broaching tool of the cone hole internal keyways, the workpiece is located through the cone section on the guide sleeve, and the internal keyways of the workpiece are axially parallel to the locating sleeve, so that a broach is parallel to the internal keyways. The broaching tool of the cone hole internal keyways achieves mass machining of the cone hole internal keyways on a broaching machine, and can ensure accuracy of the internal keyways.

The utility model taper hole internal keyway broaching frock comprises positioning sleeve and guide sleeves, and described positioning sleeve is provided with axial location end face and the outside cylinder locating surface vertical with the axial location end face;
The back segment of described guide sleeves is arranged in the positioning sleeve, and is provided with circumferential positioner between positioning sleeve and the guide sleeves;
The endoporus front end of described positioning sleeve is provided with spacing counterbore, and the middle part of described guide sleeves is provided with the location shaft shoulder that cooperates with spacing counterbore;
The leading portion of described guide sleeves is the conical section that cooperates with the workpiece taper hole, and the axes intersect of the axis of described conical section and positioning sleeve outside cylinder locating surface and the angle of two axial lines equate with the angle of workpiece taper hole bus and taper hole axis;
Described guide sleeves is provided with the broaching tool stopper slot that axially connects along it.
Further, also comprise and be used for the wedge of wedge between workpiece end face and positioning sleeve front end face;
Further, described circumferential positioner is a flat key.
The beneficial effects of the utility model: the utility model taper hole internal keyway broaching frock, it is by the location of the conical section on guide sleeves workpiece, make the internal keyway and the positioning sleeve axially parallel of workpiece, realized the parallel of broaching tool and internal keyway, the broaching tool stopper slot that is provided with on the guide sleeves can limit the position of broaching tool in the broaching process, guarantees the broaching precision; Realize processing taper hole internal keyway in enormous quantities on broaching machine by this frock, and can guarantee the precision of internal keyway.
Description of drawings
Fig. 1 is the sectional structure chart of this taper hole internal keyway broaching frock.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in the figure, present embodiment taper hole internal keyway broaching frock comprises positioning sleeve 1 and guide sleeves 2, and described positioning sleeve 1 is provided with axial location end face 11 and the outside cylinder locating surface 12 vertical with axial location end face 11; After positioning sleeve 1 was contained on the broaching machine, axial location end face 11 and outside cylinder locating surface 12 were used to limit the axial and radial position of positioning sleeve 1; Certainly in concrete enforcement, also be provided with on the positioning sleeve 1 by the position-limit mechanism that limits its circumferential position on broaching machine, in the present embodiment, the groove structure 15 of described position-limit mechanism for radially extending along positioning sleeve, position-limit mechanism also can be other structures such as circular hole or alignment pin certainly;
The back segment of described guide sleeves 2 is arranged in the positioning sleeve 1, and is provided with circumferential positioner 3 between positioning sleeve 1 and the guide sleeves 2, and circumferentially positioner 3 can guarantee positioning sleeve 1 and guide sleeves 2 both can not misplace in a circumferential direction, guarantees that broaching carries out smoothly; Circumferential positioner 3 in the present embodiment is flat key, and is simple in structure, is convenient to make; Certainly in different embodiments, circumferentially positioner 3 can also be the structures such as alignment pin that radially are provided with along positioning sleeve 1;
The endoporus front end of described positioning sleeve 1 is provided with spacing counterbore 13, and the middle part of described guide sleeves 2 is provided with the location shaft shoulder 14 that cooperates with spacing counterbore 13, and this structure is used to guarantee the axial location and the radial position of guide sleeves 2, guarantees the broaching precision;
The leading portion of described guide sleeves 2 is the conical section that cooperates with the taper hole of workpiece 4, the axes intersect of the axis of described conical section and positioning sleeve outside cylinder locating surface 12 and the angle α of two axial lines equate with the angle β of workpiece taper hole bus and taper hole axis, this structure has realized workpiece internal keyway and outside cylinder locating surface 12 axis parallels, makes that the workpiece internal keyway can be by broaching processing on broaching machine;
Described guide sleeves 2 is provided with the broaching tool stopper slot 21 that axially connects along it, and broaching tool stopper slot 21 can limit the position of broaching tool in the broaching process, guarantees the broaching precision.
Realized on broaching machine the purpose of processing work taper hole internal keyway in enormous quantities can improving the workpiece working (machining) efficiency by this frock, improved the internal keyway crudy.
