Abstract
The invention relates to a machining process for a herringbone oblique tooth key groove. The machining process comprises the following steps that a gear center line is found out, specifically, the side which is close to a gear shaft tooth part step serves a positioning datum surface, and the intersection point of a tooth groove center line and a tooth width center line as well as the gear center line are found out on a machining center through a probe; repeated measurement is conducted, specifically, the machining center clamps a centering tool which is provided with a detection probe stretching into a tooth groove, the detection probe is placed on the detected intersection point, the distances of the two sides of the detection probe to a tooth wall are detected, and if the distances of the two sides of the detection probe to the tooth wall are consistent, the situation that the detected position is correct can be determined; a key groove datum center line is milled, specifically, clockwise biasing by a certain angle is conducted on the gear center line with the positioning datum surface being a reference surface, so that a key groove datum line is obtained; and the key groove is milled, specifically, the key groove datum line is aligned, and the key groove is milled. The machining process for the herringbone oblique tooth key groove has the advantages that the position which cannot be indicated by the machining center is shown through the centering tool, operation is easy, the precision is high, and the production reliability and stability are greatly improved.
Description
Technical field
The present invention relates to a kind of field of machining, particularly to a kind of herringbone helical teeth keyway processing technique.
Background technology
When processing herringbone angular gear, owing to the gear teeth of gear have certain gradient, at processing gear internal key
Need during groove to set benchmark, in order to be processed more accurately, machining center reference centering function, but add man-hour, its
The position of centering is without concrete instruction, it is impossible to judge its accuracy, causes certain difficulty to processing.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of herringbone helical teeth keyway processing technique.
For solving above-mentioned technical problem, the technical scheme is that a kind of herringbone helical teeth keyway processing technique, its innovation
Point is: comprise the steps:
(1) gear centre line is looked for: using close tooth axle teeth portion step side as positioning reference plane, work in-process utilizes probe to look in the heart
Go out the junction point of tooth space centerline and facewidth centrage, and utilize joint to determine gear centre line；
(2) repetition measurement: machining center clamping centering tooling, centering tooling has the detection probe stretching in teeth groove, and detection is visited
Head is placed on the junction point detected, utilizes the clearance gauge detection detection probe both sides distance away from tooth wall, if two lateral extents are consistent,
Then can determine that the position having detected that is correct, if two lateral extents are inconsistent, then need again to find junction point accurately；
(3) keyseat reference center line: bias certain angle on gear centre line with positioning reference plane for the plane of reference clockwise
Obtain keyway datum line, at tooth root center keyseat datum line, and cause and include that the two sides of positioning reference plane make marks；
(4) keyseat: centering keyway datum line, and keyseat.
Further, need to do magnetic powder inspection after described keyseat.
Further, described centering tooling includes a grip shank and a detection probe, and described detection probe is for being arranged on
The round shape thing of grip shank end.
It is an advantage of the current invention that: centering tooling is used in the position that machining center cannot indicate and represents, and simple to operate,
Precision is higher, substantially increases the reliability and stability of production；The simple in construction of centering tooling, easy to use.
Detailed description of the invention
Promoting in reduction box and often can use herringbone helical teeth, its Making programme is generally divided into, welded gear, destressing tempering,
The steps such as ultrasonic examination, rough turn, gear hobbing, line centering, keyseat, magnetic powder inspection, wherein keyseat step, owing to herringbone is oblique
The particularity of tooth, keyway datum line is difficult to determine, as it is shown in figure 1, the invention discloses a kind of herringbone helical teeth keyway processing technique,
Comprise the steps:
(5) gear centre line 2 is looked for: using close tooth axle teeth portion step side as positioning reference plane 5, work in-process utilizes probe in the heart
Find out the junction point 4 of tooth space centerline 1 and facewidth centrage, and utilize joint 4 to determine gear centre line 2；
(1) repetition measurement: as in figure 2 it is shown, centering tooling includes grip shank 6 and a detection probe 7, detection probe 7 is for being arranged on
The round shape thing of grip shank end；Machining center clamping centering tooling grip shank 6, on centering tooling, detection probe 7 stretches in teeth groove,
Detection probe 7 is placed on the junction point 4 detected, utilizes clearance gauge detection detection probe 7 both sides distance away from tooth wall, if both sides
Distance is consistent, then can determine that the position having detected that is correct, if two lateral extents are inconsistent, then need again to find junction point 4 accurately；
(2) keyseat datum line 3: bias certain angle clockwise with positioning reference plane 5 for the plane of reference on gear centre line 2 and obtain
To keyway datum line, during enforcement, deflection angle can set as the case may be, at tooth root center keyseat datum line,
And cause and include that the two sides of positioning reference plane 5 make marks；
(3) keyseat: centering keyway datum line 3, and keyseat.
Ultimate principle and the principal character of the present invention have more than been shown and described.Skilled person will appreciate that of the industry,
The present invention is not restricted to the described embodiments, the principle that the present invention is simply described described in above-described embodiment and description,
Without departing from the spirit and scope, the present invention also has various changes and modifications, and these changes and improvements all fall
Enter in scope of the claimed invention.Claimed scope is defined by appending claims and equivalent thereof.
