Abstract
The present invention relates to a kind of herringbone helical teeth keyway processing technology, comprise the following steps：Look for gear centre line：So that the junction point and gear centre line of tooth space centerline and facewidth center line are found out using probe in the heart as positioning reference plane, work in-process close to tooth axle teeth portion step side；Repetition measurement：Machining center clamps centering tooling, has a detection probe stretched into teeth groove on centering tooling, and detection probe is placed on the junction point detected, detects distance of the detection probe both sides away from tooth wall, if two lateral extents are consistent, can determine that the position having detected that is correct；Keyseat reference center line：Certain angle is biased clockwise using positioning reference plane as the plane of reference on gear centre line obtains keyway datum line, keyseat：Centering keyway datum line, and keyseat.The advantage of the invention is that：The position that machining center can not be indicated borrows centering tooling and represented, and simple to operate, and precision is higher, substantially increases the reliability and stability of production.
Description
Technical field
The present invention relates to a kind of field of machining, more particularly to a kind of herringbone helical teeth keyway processing technology.
Background technology
When processing herringbone angular gear, because the gear teeth of gear have certain gradient, in processing gear internal key
Need to set benchmark during groove, to be more accurately processed, machining center reference centering function, but during processing, its
The position of centering is without specific instruction, it is impossible to its accuracy is judged, certain difficulty is caused to processing.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of herringbone helical teeth keyway processing technology.
In order to solve the above technical problems, the technical scheme is that：A kind of herringbone helical teeth keyway processing technology, it is innovated
Point is：Comprise the following steps：
(1) gear centre line is looked for：To utilize spy in the heart as positioning reference plane, work in-process close to tooth axle teeth portion step side
Pin finds out the joint of tooth space centerline and facewidth center line, and determines gear centre line using joint；
(2) repetition measurement：Machining center clamps centering tooling, has a detection probe stretched into teeth groove on centering tooling, examines
Probing head is placed on the joint detected, distance of the detection probe both sides away from tooth wall is detected using clearance gauge, if two lateral extents
Unanimously, then it can determine that the position having detected that is correct, if two lateral extents are inconsistent, need to find joint accurately again；
(3) keyseat reference center line：Using positioning reference plane as the plane of reference, biasing is certain clockwise on gear centre line
Angle obtains keyway datum line, in tooth root center keyseat datum line, and leads to the two sides including positioning reference plane and does
Mark；
(4) keyseat：Centering keyway datum line, and keyseat.
Further, need to do magnetic powder inspection after the keyseat.
Further, the centering tooling includes a grip shank and a detection probe, and the detection probe is to be arranged on
The round shape thing of grip shank end.
The advantage of the invention is that：The position that machining center can not be indicated borrows centering tooling and represented, and simple to operate,
Precision is higher, substantially increases the reliability and stability of production；The structure of centering tooling is simple, easy to use.
Embodiment
Lifting reduction box in can often use herringbone helical teeth, its Making programme is generally divided into, welded gear, destressing tempering,
The steps, wherein keyseat step such as ultrasonic examination, rough turn, gear hobbing, line centering, keyseat, magnetic powder inspection, because herringbone is oblique
The particularity of tooth, keyway datum line are difficult to determine, as shown in figure 1, the invention discloses a kind of herringbone helical teeth keyway processing technology,
Comprise the following steps：
(5) gear centre line 2 is looked for：So that close to tooth axle teeth portion step side, as positioning reference plane 5, work in-process utilizes in the heart
Probe finds out the joint 4 of tooth space centerline 1 and facewidth center line, and determines gear centre line 2 using joint 4；
(1) repetition measurement：As shown in Fig. 2 centering tooling includes a grip shank 6 and a detection probe 7, detection probe 7 is to set
Put the round shape thing in grip shank end；Machining center clamps centering tooling grip shank 6, and detection probe 7 stretches into tooth on centering tooling
In groove, detection probe 7 is placed on the joint 4 detected, and distance of the both sides of detection probe 7 away from tooth wall is detected using clearance gauge,
It if two lateral extents are consistent, can determine that the position having detected that is correct, if two lateral extents are inconsistent, need to find joint accurately again
4；
(2) keyseat datum line 3：Certain angle is biased with positioning reference plane 5 clockwise for the plane of reference on gear centre line 2
Degree obtains keyway datum line, and during implementation, deflection angle can be set as the case may be, in tooth root center keyseat benchmark
Line, and lead to the two sides including positioning reference plane 5 and make marks；
(3) keyseat：Centering keyway datum line 3, and keyseat.
The general principle and principal character of the present invention has been shown and described above.It should be understood by those skilled in the art that
The present invention is not limited to the above embodiments, merely illustrating the principles of the invention described in above-described embodiment and specification,
Without departing from the spirit and scope, various changes and modifications of the present invention are possible, and these changes and improvements all fall
Enter in scope of the claimed invention.The scope of the present invention is defined by the appended claims and its equivalents.
Claims (3)
