Detailed Description

The utility model is described in detail below with reference to the figures and the specific embodiments.

As shown in fig. 1 to 3, a gear ring diameter height measuring device includes a bottom plate 1, a positioning block 2, a guide rail 3, a measuring slide table 4, a positioning column 5, a pressing cylinder 6, two elastic bodies 7, two outer diameter measuring heads 8, two measuring blocks 9, two height measuring heads 10, two displacement sensors 11, a differential rod 12, and a distance sensor 13. Locating piece 2 and guide rail 3 set up respectively at the both ends of bottom plate 1, reference column 5 sets up in the top of locating piece 2, locating piece 2 and reference column 5 fixed connection, measure 4 horizontal slip settings of slip table on guide rail 3, measure 3 reciprocating motion of slip table 4 ability edge guide rail, guide rail 3 sets up along 1 length direction of bottom plate.

Two elastomers 7 set up on measuring slip table 4, and two elastomers 7 corresponding one end respectively with two external diameter gauge heads 8 fixed connection, two elastomers 7 other one end respectively with differential rod 12 and distance sensor 13 fixed connection, differential rod 12 pushes up on distance sensor 13, two measuring block 9 slide from top to bottom respectively and set up in the upper end and the lower extreme of measuring slip table 4, two high gauge heads 10 fixed mounting respectively on two measuring block 9, two equal fixed mounting of displacement sensor 11 are on measuring slip table 4, and two displacement sensor 11 are used for collecting the data of the vertical displacement distance of two high gauge heads 10 respectively.

The pressing cylinder 6 is arranged above the positioning block 2.

The positioning block 2 is vertically and fixedly connected with the positioning column 5.

The two elastic bodies 7 are arranged between the measuring sliding table 4 and the positioning column 5.

When the utility model is used for measurement, firstly, the gear ring 14 is sleeved on the positioning column 5 and then the gear ring 14 is placed on the positioning block 2. Then the telescopic rod of the pressing cylinder 6 extends outwards to press the gear ring 14, so that the gear ring 14 is fixed. The measuring sliding table 4 slides and approaches to the gear ring 14 along the guide rail 3, so that the two outer diameter measuring heads 8 move along the outer wall of the gear ring 14, the distance between the two outer diameter measuring heads 8 is constantly changed, the two elastic bodies 7 are elastically deformed, the two elastic bodies 7 respectively drive the differential rod 12 and the distance sensor 13 to move, the distance sensor 13 measures the maximum value of the distance between the distance and the differential rod 12 and transmits data to an SPC measuring workstation, and the maximum value of the distance between the original distance between the two outer diameter measuring heads 8 and the distance between the distance and the differential rod 12 measured by the distance sensor 13 is the data of the diameter of the gear ring 14.
