Embodiment
1-8 describes a kind of embodiment of the present utility model below in conjunction with the accompanying drawings.
For the cubing of annular groove depth survey, there is matrix 1, described matrix 1 is placed in the endoporus of workpiece 2 and the right side of matrix 1
The arc surface of outer wall is bonded after being matched with the inner hole wall of workpiece 2, is formed with described matrix 1 in stepped hole 3 and stepped hole 3 and is provided with elasticity
Measurement apparatus, the stepped top of hole 3 are provided with the pressing device for being used for controlling elasticity measuring device, made by adjusting pressing device
Elasticity measuring device right-hand member probes into and pushed against the survey realized after the inwall of annular groove 4 on the inner hole wall of workpiece 2 to the depth of annular groove 4 automatically
Amount；Specifically, the elasticity measuring device includes measuring staff 5, spacing back-up ring 6 and spring 7, the measuring staff 5 is placed in stepped hole 3
And coordinate with the stepped gap of hole 3, the left end of measuring staff 5 is formed with the mounting groove 8 being adapted with spacing back-up ring 6 and spacing back-up ring 6 fills
In in mounting groove 8, the limited step 10 and gauge head 9 of the right-hand member of measuring staff 5 are located at the stepped right-hand member of hole 3, and the spring 7 is sheathed on
On measuring staff 5 and spring 7 is located between limited step 10 and the step surface 11 at the middle part of stepped hole 3, will be surveyed by adjusting pressing device
Bar 5 compresses or gauge head 9 is probeed into automatically after unclamping and push against measurement of the realization to the depth of annular groove 4 after the inwall of annular groove 4；Specifically,
The end of gauge head 9 is less than the 0.1-0.2mm of the gullet radius of annular groove 4 for the spherical radius of spherical structure and gauge head 9,
Distance of the end of gauge head 9 away from the right side of limited step 10 is more than the 2-3mm of the depth of annular groove 4, the middle part of mounting groove 8 to survey
The distance of the left side of bar 5 is more than the 2-3mm of the depth of annular groove 4；Specifically, the pressing device is annular knurl housing screw 12, it is described
Screwed hole 13 that is vertical with stepped hole 3 and connecting is formed with matrix 1, the annular knurl housing screw 12 will after being screwed with screwed hole 13
Elasticity measuring device compresses or realizes measurement of the elasticity measuring device to the depth of annular groove 4 after unclamping.
In this structure, the structure of measuring staff 5 is step, and shaft part coordinates with the stepped left end of hole 3 for small―gap suture, measuring staff 5
