Detailed Description
The utility model is further illustrated by the following examples in conjunction with the accompanying drawings.
In the embodiment, the radial runout detection mechanism suitable for the multi-diameter carrier roller comprises a detection head, a spring reset mechanism and a displacement detector 11, wherein the detection head is connected with the displacement detector 11 through the spring reset mechanism; the detection head comprises a roller 1, a pin shaft 2, an installation seat 3 and a guide pillar connecting plate 4, wherein the roller 1 is fixed on the installation seat 3 through the pin shaft 2, and the installation seat 3 and the guide pillar connecting plate 4 are connected with each other by using screws and pins; the spring reset mechanism comprises two guide posts 5, springs 6, linear bearings 7, linear bearing mounting plates 8 and displacement measuring plates 9, wherein the number of the guide posts 5 is two, the guide posts 5 sleeved with the springs 6 are inserted into the linear bearings 7 according to clearance fit, the linear bearings 7 are fixed in the linear bearing mounting plates 8 by using screws, the left ends of the two guide posts 5 are connected with the guide post connecting plates 4 by using screws, the right ends of the two guide posts 5 are connected with the displacement measuring plates 9 by using screws, and adjusting screws 13 are arranged at two ends of the displacement measuring plates 9 and used for manually adjusting the distance and the flatness of the displacement measuring plates relative to the displacement detector 11; the linear bearing mounting plate 8 is fixed to the base plate 12 by screws and pins, the displacement detector 11 is mounted on the detector mounting plate 10, and then fixed to the base plate 12 by screws and pins.
In practical application, the roller of the precision detection head with the diameter of 10-30mm, the thickness of 5-10mm and the diameter jump of less than or equal to 0.02mm is tightly propped against the surface of a roller workpiece rotating on a workbench after one end is pushed out by a cylinder, and after the roller contacts with a rotating phi 89-phi 219mm roller, the roller extrudes the roller 1, and the roller can generate displacement to do linear motion due to radial change from a point on the surface of the roller to a rotating shaft, and because the right end of the detection head is connected with a spring reset mechanism, the displacement measurement plate 9 can do reciprocating linear motion together with the roller 1. The displacement detector 11 propped against the right end of the displacement measuring plate 9 continuously outputs a real-time displacement value to the PLC of the automatic equipment; after the carrier roller rotates once, the radial runout value of the carrier roller at the position is obtained by subtracting the minimum value from the highest value of the reading displayed by the displacement detector.
