Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Please refer to fig. 1-4, an accurate measuring device of bearing outer diameter, including bottom plate 1, bottom plate 1 top fixedly connected with backup pad 2, and backup pad 2 top fixedly connected with square shell 3, square shell 3 all runs through all around by round bar 4, and round bar 4 outside all welds has spacing plectane 5, round bar 4 inboard all welds has arc splint 6, round bar 4 surface all overlaps and is equipped with spring 7, 7 one end of spring all fixed connection are the 3 inner walls of square shell, 7 other ends of spring all fixed connection are on arc splint 6, 5 right side welding of spacing plectane at square shell 3 top have pointer 8, and the 8 rear sides of pointer are provided with measuring plate 9, measuring plate 9 bottom fixed connection is at 3 tops of square shell.
Specifically, round hole 10 has all been seted up all around to square shell 3, and the inner wall diameter that round hole 10 set up and round bar 4 surface diameter phase-match for inside round bar 4 can insert round hole 10, reached round bar 4 can be at the inside gliding purpose of round hole 10.
Specifically, all fixedly connected with stereoplasm rubber board 11 in the inboard of arc splint 6, when pressing from both sides the dress bearing, because the roughness of stereoplasm rubber board 11 is great for the bearing presss from both sides more stably firm of dress, the distance that four group's stereoplasm rubber boards 11 and 3 central points of square shell put equals for the location bearing makes the bearing centre of a circle and the center of square shell 3 on same straight line.
