Sensor is distributed on the turntable 11 of testing agency, the spy for detecting tooth-face roughness can be used in the present embodiment
Needle 14, specifically, using surfagauge SJ-210 to flank profil surface carry out roughness concentration, 300 μm of measurement range
(± 150 μm), measurement process surfagauge SJ-210 carry out roughness inspection to flank profil surface using micro- induction mode
It surveys, firstly, second support arm 9 is mobile to tooth profile by surfagauge SJ-210 detection probe, until detection
Probe 14 stops movement after issuing effective detecting distance；Secondly, by the appearance profile in the theoretical model in computer, to the
The stroke of two support arms 9 is planned and is controlled, thus realize to surfagauge SJ-210 detection probe 14 with
The control of flank of tooth detecting distance.Control module rotates turntable 2 with certain speed, and realizes that detection is used
Probe 14 and gear rotation amount be linked detection, the data after detection import in computer, and most to experimental data progress
Small square law and process of fitting treatment, thus obtain tooth-face roughness value, non-of the least square method and process of fitting treatment of specific computer
Case protection is crucial, does not do burdensome description herein.Further, multiple sensors can also be distributed on turntable 11, such as can also be same
When include for profile tolerance detection probe 15, profile information etc. is obtained by the detection to flank of tooth echo.Due to turntable 11
It is coaxially connected with turn-button 12, therefore corresponding sensor can be allowed to keep contour with gear 7 to be detected under the control of turn-button 12
Degree, and then realize the conversion of detection device difference detection function.
Above-mentioned apparatus is taken, gear teeth face detection will be carried out by following steps:
Step 1: it is lain in a horizontal plane on scroll chuck 3 by gear 7 and device alcohol wipe, and by gear 7, passes through circle
Heart detector 6 realizes scroll chuck 3 and 1 center shaft alignement of pedestal, is adjusted in synchronism three buckles of scroll chuck 3, realizes tooth
Take turns 7 centers and 1 center shaft alignement of pedestal and clamping gear 7；
Step 2: distance between probe 14 and gear 7 is adjusted by second support arm 9, it is ensured that probe 14, which is not interfered, does not collide tooth
Face, adjusts the height and angle of scanner 4, and sticks the patch for constructing coordinate system in patch notch 5；
Step 3: turntable 11 is adjusted by turn-button 12, so that profile tolerance detection probe 15 is directed at the flank of tooth, is examined by profile tolerance
Probing head 15 obtains gear teeth face shape, and determines the path of probe 14；
Step 4: controlling turntable 2 by control module and rotate, and turntable 2 often turns over a unit angle, and probe 7 is flat
Platform 10 constantly moves up and down under driving, and realizes to gear teeth face roughness measurement；
Step 5: gear profile graph data is obtained by scanner 4 simultaneously；
