Fig. 3 is a schematic structural view (sectional view) of the present invention.
Detailed Description
The device 100 for measuring the outer diagonal diameter of the ball cage as shown in fig. 1 to 3 comprises an inclined platform 110, wherein the periphery of the inclined platform 110 is connected with a planar platform 130 through a circumferential connecting surface 120, and the centers of the inclined platform 110 and the planar platform 130 are connected through a through groove structure 140. In addition, a positioning block 131 is further disposed on the central axis of the planar platform 130. The top end of the positioning block 131 is provided with a chamfer structure.
The surface of the inclined platform 110 is made of a tungsten-inlaid steel structure, and the inclination angle of the inclined platform 110 is 27 °.
The through groove structure 140 includes a first through groove 141, a second through groove 142 and a third through groove 143 connected to each other, the diameter of the second through groove 142 is larger than that of the first through groove 141, and the third through groove 143 is inclined.
Because of possessing the above structure, the utility model discloses a theory of operation lies in:
a cage (not shown) is placed on the ramp platform 110 to find the maximum and minimum inflection points of the cage, which are the inner diagonal diameters of the cage, and the next set of outer diagonal diameters is measured at 60 ° rotation.
