Embodiment Construction

[0037] See figure 1 with figure 2 , Processing method of multi-slope taper gauge:

[0038] 1. Blanking: use GCr15 or GrMn as the material and forging the blank, the diameter is 8-10mm, the length is 20mm.

[0039] 2. Rough turning gauge: The gauge leaves 5mm margin for quenching and tempering.

[0040] 3. Tempering: HRC <10.

[0041] 4. Precision car gauge:

[0042] (1) The straight outer circle C, the diameter of the grinding allowance is 0.80mm, and the length is (L 3 -L 2 ) Car Cheng.

[0043] (2) Machining the center hole of the M end, the 60° cone length is 0.8~1.5mm.

[0044] (3) Car cone A, according to diameter Φ 1 Turn into a straight outer circle with a grinding allowance of 1mm, and the length is L 2 Car into, angle α 1 Processing in the later process.

[0045] (4) Car inclined shoulder B, the actual processing angle is greater than α 2 The diameter of the car is the diameter of the straight outer circle C Φ 3 car.

[0046] (5) Car angle α 1 , Starting from the actual big end o...

Abstract

The invention discloses a processing method of a multi-inclination taper gauge which consists of a cone A, a sloping shoulder B and a straight excircle C; the processing steps include blanking, rough lathing of the gauge, hardening and tempering, finish lathing of the gauge, quenching, grinding a centre bore, coarse grinding of two end faces, coarse grinding of the gauge, seasoning, precision grinding of the end face M, bench work grinding of the end face M, precision grinding of the straight excircle C, precision grinding of the cone A, precision grinding of the sloping shoulder B, etc. The key points of processing are as follows: the length of the conical surface of the centre bore at the M end of the base level of the gauge cone A is 0.80mm-1.5mm; the grinding margin of the diameter is0.80mm-1mm; the angle Alpha 2 must be enlarged in lathing; heat treatment includes artificial seasoning and cold treatment. The method can solve the problems of high processing difficulty and easy scrapping of the multi-inclination taper gauge, thus ensuring the normal processing of the multi-inclination taper gauge.

Description

Technical field [0001] The processing method belongs to the field of measuring tool processing, and specifically relates to the processing of a multi-slope taper gauge. Background technique [0002] The general taper gauge is a general-purpose measuring tool with only one slope in structure. It is widely used in equipment and tooling, while the multi-slope taper gauge is a special measuring tool. Its basic structure consists of cone A, oblique shoulder B, and straight outer circle. C composition, high dimensional accuracy, high processing difficulty, problems in any link in the processing, it is easy to cause the product to be scrapped. Summary of the invention [0003] The present invention provides a method for processing a multi-slope taper gauge, which aims to solve the problems of high processing difficulty and easy scrapping of the multi-slope taper gauge, thereby ensuring the normal processing of the multi-slope taper gauge. [0004] The multi-slope taper gauge is composed o...
