Specific embodiment
The utility model is described in further detail below with reference to embodiment:
Embodiment
As shown in FIG. 1 to FIG. 2, a kind of hole size measuring device of hole class workpiece, including measuring cylinder 1, the first clamp 2,
Second clamp 3 and dial gauge 8, along its length through axis hole is provided with, 1 side of measuring cylinder is provided with to be connected measuring cylinder 1 with axis hole
Loose slot 10, be successively arranged transmission shaft 6 and spring lever 4 in the axis hole of measuring cylinder 1,4 end of spring lever is fixed with nut 41, spiral shell
Mother 41 and the axis hole inside thread of measuring cylinder 1 are connected and fixed, and spring 5 is set on spring lever 4, and the first clamp 2 have clamp handle
A22, clamp handle A22 are across loose slot 10 and are held on transmission shaft 6 and spring 5.Dial gauge 8 includes gauge head cylinder 9 and percentage
Table gauge head 81, gauge head cylinder 9 are fixed on measuring cylinder 1 close to 7 one end of axle sleeve, 81 end activity of dial indicator measuring head pass through gauge head cylinder 9 with
The corresponding contact of transmission shaft 6.There is second clamp 3 clamp handle B32, clamp handle B32 to be fixed in the loose slot 10 of measuring cylinder 1.This
Preferred first clamp 2 of utility model and the second clamp 3 are arranged in parallel.One end end of first clamp 2 far from clamp handle A22
The first measuring rod 21 is fixed on the outside of portion, the second clamp 3 are fixed with the second measuring rod far from one end end outside of clamp handle B32
31, the first measuring rod 21 is located along the same line with the second measuring rod 31.
As shown in Figure 1, be provided with the sliding slot 11 being parallel to each other with axis hole inside measuring cylinder 1, clamp handle A22 end bosses have with
