Problems solved by technology

[0003] Existing involute spline plug gauges for machining inspection (such as figure 1 , figure 2 As shown), the tooth material is usually made of alloy tool steel CrMn, and the quenching hardness is HRC60~63. Since the involute plug gauge needs to be inserted and pulled out continuously during use, the plug gauge of this kind The service life is extremely limited, because its surface cannot be titanium-plated, so once it is worn out, it cannot be repaired, but can only be scrapped, resulting in great waste

Embodiment Construction

[0023] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, but not for limiting the protection scope of the present invention.

[0024] Such as image 3 As shown, the gauge body 1 of the involute spline inspection plug gauge of the present invention is made of scrapped high-speed steel hobbing cutters, and the gauge body 1 is covered with a titanium-coated hard film, and the titanium-coated hard film can be nitrogen Titanium hard film, titanium carbide hard film, titanium carbonitride hard film or titanium oxide hard film, titanium nitride hard film is used in this embodiment, and the thickness of the titanium-coated hard film is between 0.001-0.005.

[0025] The method for manufacturing the involute spline inspection plug gauge of the present invention comprises the following steps:

Abstract

The invention discloses an involute spline inspection plug gauge comprising a gauge body and a handle. The gauge body is formed by adopting a waste high-speed steel hob and a layer of titanizing hard coating which is covered thereon. The invention not only sufficiently utilizes waste resource, but also enhances hardness of the plug gauge to HRC63-66, greatly improving service life, and the plug gauge can be reused when the primary precision is recovered by titanizing technique after abrasion limit is reached. The invention also relates to a method for processing involute spline inspection plug gauge by using a waste high-speed steel hob.

Description

technical field [0001] The invention relates to a measuring tool, in particular to an involute spline inspection plug gauge and a manufacturing method thereof. Background technique [0002] The involute spline plug gauge is a common measuring tool used to check whether the spline hole meets the requirements. [0003] Existing involute spline plug gauges for machining inspection (such as figure 1 , figure 2 As shown), the tooth material is usually made of alloy tool steel CrMn, and the quenching hardness is HRC60~63. Since the involute plug gauge needs to be inserted and pulled out continuously during use, the plug gauge of this kind The service life is extremely limited, and since its surface cannot be titanium-plated, it cannot be repaired once it is worn out, and it can only be scrapped, thereby causing great waste. [0004] In processing enterprises, a large number of scrapped gear hobbing cutters can be produced every year. Most of the gear hobbing cutters are proces...
