Abstract
Applicant has disclosed a chamfer gage with interchangeable anvil assemblies which can measure the diameter of chamfered holes and the chamfer angle (up to 135°). In the preferred embodiment, the chamfer gage comprises: an indicator housing; a compression fitting, attached to the housing, for securing an indicator spindle for movement inside the housing; and an interchangeable anvil assembly, having an anvil body with a depressible anvil or plunger inside, which can be detachably connected to the indicator housing by a threaded thumb ring rotatably mounted on the housing. Another interchangeable anvil assembly can be swapped within thirty seconds to measure the chamfer of a different hole size.
Claims8
A method of substituting an interchangeable anvil assembly in a chamfer gage, the method comprising:
- a. an end-user removing an interchangeable first anvil assembly, having a first anvil body with a depressible first anvil, from an indicator housing of the chamfer gage by unscrewing a threaded ring, rotatably attached to the housing, from a threaded first collar in a top portion of the first anvil body;
- b. the end-user attaching an interchangeable second anvil assembly, having a second anvil body with a depressible second anvil;
- to the housing by screwing the threaded ring onto a threaded second collar of the second anvil body;
- and
- c. wherein the threaded first collar and the threaded second collar are substantially identical.
A method of substituting interchangeable anvil assemblies in a chamfer gage, the method comprising:
- a. an end-user removing an interchangeable first anvil assembly from a remainder of the chamfer gage by unscrewing a threaded ring, rotatably attached to the remainder, from a threaded first collar of the first anvil assembly;
- i. wherein the first anvil assembly includes a first anvil body with a depressible first anvil housed in the anvil body;
- and
- ii. wherein the first anvil body includes the first threaded collar;
- b. the end-user attaching a second interchangeable anvil assembly, having a second anvil body with a depressible second anvil to the housing by screwing the threaded ring onto a threaded second collar of the second anvil body;
- and
- c. wherein the threaded first collar and the threaded second collar are substantially identical.
A chamfer gage comprising:
- a. an indicator housing of the chamfer gage;
- b. a compression fitting to secure an indicator spindle to the housing;
- and
- c. an interchangeable anvil assembly having an anvil body, with a depressible anvil housed inside the body, detachably connected to the indicator housing by an internally threaded ring threaded onto a threaded collar of the anvil body.
