specific Embodiment approach 1

[0014] Specific implementation mode one: combine figure 1 and figure 2 Describe this embodiment, the inspection method for the bending deformation of the pocket beam of the square hole cage, the steps are as follows:

[0015] 1. Place the square hole cage on the detection table of the three-dimensional optical measuring instrument, so that the pocket 2 of the square hole cage is perpendicular to the projection direction;

[0016] Two, according to the image characteristics of the computer after projection by the three-dimensional optical measuring instrument, collect the positions of the two crossbeam projections 30 of the pocket hole in the computer, and make corresponding calculations with respect to the inner edge lines of the pocket projection through the two crossbeam projections 30 Crossbeam auxiliary line 10, crossbeam auxiliary line 10 is the line connecting the two intersection points of the crossbeam projection relative to the pocket projection's inner edge line an...

specific Embodiment approach 2

[0025] Specific implementation mode two: combination figure 1 and figure 2 To illustrate this embodiment, the beam auxiliary line 10 in step 2 is made by two intersection points of the inner edge line of the beam projection relative to the pocket projection and the side beam projection. Such a design can avoid error in the position of the auxiliary line due to the bending of the beam, thereby affecting the final detection result. Other compositions and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0026] Specific implementation mode three: combination figure 1 and figure 2 Describe this embodiment, measure the distance between the first auxiliary line 11 and the second auxiliary line 21 described in step 4, take multiple measurements of different positions between the first auxiliary line 11 and the second auxiliary line 21 measurements. This design avoids errors caused by silver plating on the surface of the cage or other special conditions. Other compositions and connections are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The invention provides a method for inspecting bending deformation of a square hole holding frame packet cross beam. The method settles the defects of low inspection result accuracy and easy original structure damage of a holding rack in inspection in an existing method for inspecting the bending deformation of the square hole holding frame packet cross beam. Corresponding cross beam auxiliary lines are drawn through projected inner edge lines of two cross beams relatively to a pocket. The middle positions of two cross beam auxiliary lines are selected and connected. A first auxiliary line which is vertical to the pocket beam is drawn at the middle position of the connecting line. Corresponding split claw auxiliary lines are drawn along the inner edge lines of two split claw projections which are projected relative to the pocket. The middle positions of the two split claw auxiliary lines are selected and connected. A second auxiliary line which is vertical to the pocket side beam is drawn at the middle position of the connecting line. On condition that a distance between the first auxiliary line and the second auxiliary line is larger than or equal with 0.1mm, relatively bending of the square hole holding frame packet cross beam is proved. The method is used for testing holding frame deformation.

Description

technical field [0001] The invention relates to an inspection method, in particular to an inspection method for bending deformation of a pocket beam of a square hole cage. Background technique [0002] Usually, the beam of the cage is easily bent during the processing of the locking point of the cage, and the qualified cage pockets are in surface contact with the rolling elements, but the cage pockets with curved beams are in contact with the rolling elements. The abnormal contact between bodies is point contact, figure 1 Shown is a schematic diagram of the distribution of contact point 1 during abnormal contact. In order to ensure the machining accuracy of the square hole cage pocket, it should be controlled from two aspects; one is the parallel difference between the pocket side beam and the base surface, and the other is the pocket hole. The vertical difference between the beam and the base surface; but sometimes these two inspection methods cannot effectively detect the...
