Embodiment
Laser tester for cam profile as shown in Figure 1, comprise pedestal 1, be arranged on servo-drive system 2 on the pedestal 1, by the indexing mechanism 3 of servo-drive system 2 controlled motions, be arranged on laser head 4 on the indexing mechanism 3, the fixing measurement piece 7 that is arranged on tested cam 5 on the indexing mechanism 3, the rotating cam bawl 6 of going up and being meshed with tested cam 5, is connected and is used for the laser beam that reflector laser head 4 launches with cam bawl 6.
Servo-drive system 2 comprise the perpendicular y axle base 22 of x axle base 23, direction of motion and x axle base 23, respectively drag two high precision roller leading screws 24, the control high precision roller leading screw 24 of x axle base 23 and 22 motions of y axle base servomotor 25, intersect and be arranged to four rectilinear orbits 21 of " well " font structure, x axle base 23 and y axle base 22 move along rectilinear orbit 21.
The direction of motion of definition x axle base 23 is the x direction of principal axis, the direction of motion of y axle base 22 is the y direction of principal axis perpendicular with the x direction of principal axis, by the circular motion along the synthetic indexing mechanism 3 of the axial rectilinear motion of y along axial rectilinear motion of x and y axle base 22 of x axle base 23.Servo-drive system 2 comprises two servomotors 25, and one of them servomotor 25 drives the motion of x axle base 23 on the x direction of principal axis, and another servomotor 25 drives the motion of y axle base 22 on the y direction of principal axis, has improved the indexing accuracy of indexing mechanism 3 greatly.
As shown in Figure 1, pedestal 1 is provided with dead axle 9, in the present embodiment, tested cam 5 comprises cam body 52 and 51 two parts of cam base, wherein, cam base 51 is used for to tested cam 5 centering by key and the top that is bolted to dead axle 9, cam body 52 is connected with cam base 51 by bolt, finishes the location positioning of cam body 52.
Servo-drive system 2 control linkages are rotated around dead axle 9 at the laser head 4 of indexing mechanism 3 ends, and, keep laser head 4 and the measurement piece 7 that is connected on the cam bawl 6 to rotate synchronously, like this, the relative motion of laser head 4 and cam bawl 6 only is a rectilinear motion, by Laser Measurement 4 and measure that relative distance changes between the piece 7, determines the change in radius value of tested cam 5, be converted into the rate of change of the contour curve of tested cam 5 by processor unit, promptly determine the machining precision of contour curve.
Laser tester for cam profile shown in Figure 1 comprises that also being used for welding cam roller 6 makes itself and tested cam 5 mesh tight and gapless pneumatic fitting 8, by adjusting air pressure, make between tested cam 5 and the cam bawl 6 and well contact, guarantee the elastic deformation minimum between the two, to reach very high measuring accuracy.
As shown in Figure 3, measure piece 7 and have step structure, corresponding because present embodiment adopts high-precision laser head 4, the limited action distance of its laser beam is just less, measures the step structure of the laser entrance face of piece 7, the measurement range of having amplified laser head 4.
