Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail with reference to the following embodiments and accompanying drawings.

As shown in fig. 1-4, the utility model relates to an automatic centering device that compresses tightly of rotor balancing machine, lift cylinder 2 is vertical to be installed on base 2. And two support rods 3 are provided, one support rod is connected with the lifting cylinder 2 through a lifting shaft 203, is hinged with the work-shaped plate 4 through a bolt, and is hinged with the work-shaped plate 4 through a bolt and is fixed on a workbench 9 of the balancing machine. Two ends of the I-shaped plate 4 are provided with shaft hole convex blocks 402, and guide rails 401 are arranged below two sides in the I-shaped plate. The telescopic cylinder 5 is arranged on the I-shaped plate 4 and is connected with the pressure plate 6 through a telescopic shaft 503. The pressing plate 6 is arranged on the I-shaped plate 4 through an I-shaped plate rail 605, two groups of symmetrical pressing arms 602 are arranged at the front end of the pressing plate 6, an arc-shaped pressing block 601 is arranged at the front end of each pressing arm 602, and a displacement sensor 603 and a buffer rod 304 are arranged on the side surface of the pressing plate 6. Two groups of arched embedded pieces 7 are symmetrically arranged on the rotor seat 8, the middle of each arched embedded piece 7 is provided with a rectangular groove 701 and an arc slope 702, and the distance between the two groups of arched embedded pieces 7 is adjustable. The photoelectric sensor 801 is mounted on the rotor base, on one side of the arcuate insert 7.
