[0028] In the three-dimensional contour measuring device for gears based on line laser scanning of the present utility model, a plurality of support blocks 7 are provided on the bottom outer wall of the base 1. The plurality of support blocks 7 are evenly distributed at the four corners of the bottom of the base 1, which can provide a stable supporting effect and ensure the stability of the device during use.

[0032] During use, first place the gear on a fixing seat 8 and ensure that an arc-shaped plate 13 is located inside the gear ring. Then start a first motor 11 to drive the gear 12 to rotate. Since the arc-shaped plate 13 is meshed with the gear 12 through a rack 15, the arc-shaped plate 13 can be driven to move until the outer wall of the arc-shaped plate 13 contacts the inner wall of the gear, so as to fix the gear and ensure that the gear is located at the center position of the fixing seat 8. Then start an electric lifting rod 5 to drive a pressing plate 6 to descend, providing a further fixing effect for the gear from the top to ensure that the gear is in a horizontal state, thereby ensuring the measurement accuracy of the gear. Then start the third motor 21 and the fourth motor 27 respectively to drive the first screw rod 22 and the second screw rod 28 to rotate. Since the fixing plate 3 is threadedly connected to the first screw rod 22 through the guide block 23 and the fixing block 25 is threadedly connected to the second screw rod 28, the positions of the fixing plate 3 and the fixing block 25 can be adjusted, and thus the position of the measuring head 26 can be adjusted until it is adjusted to a suitable position. Then start a second motor 18 to drive a second bevel gear 19 to rotate. Since a first bevel gear 17 is meshed with the second bevel gear 19, the fixing seat 8 can be driven to rotate, so as to drive the gear to rotate, and further facilitate the measurement of the gear by the measuring head 26.
