The spherical hole radius measuring tool comprises a measuring anvil , a dial gauge, a probe and a measuring rod, wherein the measuring anvil is provided with a through hole; the through hole is arranged along the axial direction of the measuring anvil; one end of the measuring anvil is connected with the dial gauge; the other end of the measuring anvil is provided with a flange; the flange extends towards the axial direction of the measuring anvil; the probe of the dial gauge extends into the through hole of the measuring anvil; one end of the measuring rod extends into the through hole of the measuring anvil and is connected with the probe; the other end, disposed out of the through hole, of the measuring rod, is provided with an radial projection; and the radius of the radial projection is smaller than the radius of the flange on the measuring anvil. By using the spherical hole radius measuring tool, the spherical radius and deviation can be quickly measured after a workpiece is processed, thus whether the workpiece is qualified can be determined.

Description

The survey instrument of sphere hole radius
Technical field
The utility model relates to a kind of survey instrument of sphere hole radius.
Background technology
Measurement to the radius size of the inside and outside circular arc of incomplete part damaging and sphere at present, the chord length of employing measurement arc, action value are again by calculating conventionally.Owing to limit by survey instrument and measurement means, often there is deviation in the chord length recording, action data and physical size, affects the accuracy of final radius calculation result, affects part mapping.
Summary of the invention
Fundamental purpose of the present utility model is to provide a kind of survey instrument of sphere hole radius, the utlity model has and can after workpiece processing, promptly measure radius and the deviation of sphere, thereby judge that whether workpiece is qualified.
The survey instrument of sphere hole radius, comprise gage button, dial gauge, gauge head and measuring staff, described gage button is provided with through hole, this through hole is axial arranged along gage button, one end of gage button is connected with dial gauge, the other end flange of gage button, this flange is to the radially extension of gage button, the gauge head of dial gauge extend in the through hole on gage button, one end of measuring staff extend in the through hole of gage button and is connected with gauge head, the other end that is positioned at the measuring staff of through hole outside is provided with radial protrusion, and the radius of this radial flange is less than the radius of gage button upper flange.
In the through hole of described gage button, be provided with sleeve, described measuring staff and sleeve are slidably matched.
The periphery of described gage button is provided with threaded hole, and one end of a holding screw locks the axial location of measuring staff after being threaded with threaded hole.
Adopted such scheme, by the basic size of spherical radius, calculated t value, and with gauge block to good t value, guarantee that dial gauge has certain decrement, writes down the indicating value t of dial gauge 1.During measurement, gage button is extend in sphere hole and with the wall of sphere hole and contacted, the radial protrusion of measuring staff is extend in sphere hole and with the wall of sphere hole contact (because the radius of radial flange is less than the radius of gage button upper flange, therefore, the diameter at the position that radial flange is received is less than the diameter at the position that flange touches), the indicating value of dial gauge is t 2, dial gauge change in size is Δ t=t 1-t 2, according to following formula, calculate spherical radius R:
R = D 2 4 - ( t + Δt ) - d 2 4 2 ( t + Δt ) + D 2 4
In above formula, D is protruding diameter, the diameter that d is radial protrusion.
The utlity model has and can after workpiece processing, promptly measure radius and the deviation of sphere, thereby judge that whether workpiece is qualified.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
1 is gage button, and 1a is flange, and 2 is dial gauge, and 3 is gauge head, and 4 is measuring staff, and 4a is radial flange, and 5 is sleeve, and 6 is holding screw, and 7 is workpiece.
Embodiment
With reference to Fig. 1, the survey instrument of a kind of sphere hole radius of the present utility model, comprises gage button 1, dial gauge 2, gauge head 3 and measuring staff 4.Described gage button 1 is provided with through hole, and this through hole is axial arranged along gage button 1.One end of gage button 1 is connected with dial gauge 2, the other end flange 1a of gage button 1, and this flange 1a is to the radially extension of gage button.The gauge head 3 of dial gauge 2 extend in the through hole on gage button 1.One end of measuring staff 4 extend in the through hole of gage button 1 and is connected with gauge head 3, is provided with sleeve 5 in the through hole of described gage button 1, and described measuring staff 4 is slidably matched with sleeve 5, by sleeve, can increase the precision that measuring staff moves.The periphery of described gage button 1 is provided with threaded hole, and one end of a holding screw 6 locks the axial location of measuring staff 4 after being threaded with threaded hole.The other end that is positioned at the measuring staff 4 of through hole outside is provided with radial protrusion 4a, and the radius of this radial flange 4a is less than the radius of gage button upper flange.
During use, by the basic size of spherical radius, calculate t value, and with gauge block to good t value, assurance dial gauge 2 has certain decrement, writes down the indicating value t of dial gauge 2 1.During measurement, gage button 1 is extend in workpiece 7 sphere holes and with the wall of sphere hole and contacted, the radial protrusion of measuring staff 4 is extend in sphere hole and with the wall of sphere hole contact (because the radius of radial flange is less than the radius of gage button upper flange, therefore, the diameter at the position that radial flange is received is less than the diameter at the position that flange touches), the indicating value of dial gauge is t 2, dial gauge change in size is Δ t=t 1-t 2, according to following formula, calculate spherical radius R:
R = D 2 4 - ( t + Δt ) - d 2 4 2 ( t + Δt ) + D 2 4
In above formula, D is protruding diameter, the diameter that d is radial protrusion.
In addition, the utility model does not need to know the physical size of R, only need measure R whether in margin tolerance, so, in advance by the deviometer up and down of R, calculate the upper lower deviation of corresponding Δ t, according to the Δ t numerical value recording, just can determine whether out-of-size of spherical radius.
