specific Embodiment approach 1

[0019] Specific implementation mode one: combine figure 1 and figure 2 Describe this embodiment, a kind of steam seal measuring tool processing method, it comprises the following steps:

[0020] Step 1: Roughly turn each part on an ordinary lathe, each outer circle and end face should be heavy-duty on one side by 3mm, and the inner hole and the tooth surface of the steam seal should be heavy-weight on one side by 3mm;

[0021] Step 2: heat treatment, the workpiece is heat treated to HRC31-35;

[0022] Step 3: Finish turning each part of the CNC lathe, end face A2, end face B3, end face C4 and end face D5, each end face has a volume of 0.3 mm, and the rest of the parts are fine-turned to the specified size;

[0023] Step 4: Grinding on a surface grinder, grinding the end face C4 and the end face D5;

[0024] Step 5: The fitter draws the center line;

[0025] Step 6: Wire cutting machine, cut the gas seal measuring tool along the middle split surface line;

[0026] Step 7:...

specific Embodiment approach 2

[0029] Specific implementation mode two: combination figure 1 To illustrate this embodiment, the cutting parameters in step 1 are: rotational speed 180r / min, feed rate 0.3mm / r, cutting depth 2mm. Beneficial effects of this embodiment: good cutting effect. Others are the same as the first embodiment.

specific Embodiment approach 3

Abstract

The invention discloses a vapor seal measuring tool machining method, and solves the problem of difficult precision guarantee in a traditional vapor seal measuring tool. The vapor seal measuring toolmachining method comprises the following steps: all parts are roughly turned on a general lathe; the single-surface release quantity of each outer circle and end surface is 3 mm; the single-surface release quantity of each inner hole and vapor seal tooth surface is 3 mm; heat treatment: workpieces are heated to HRC 31-35; all the parts are finely turned by a numerical control lathe; the release quantity of each surface of an end surface A, an end surface B, an end surface C and an end surface D is 0.3 mm; the rest parts are finely turned to stated sizes; the end surface C and the end surface Dare grinded on a plane grinding machine; middle surface lines are drawn by bench workers; a linear cutting machine tool cuts off vapor seal measuring tools along the middle surface lines; a broach grinding machine grinds a surface A firstly, and then, grinds a surface B, so that the surface A and the surface B meet the standards; and each edge is rounded to finish machining. The vapor seal measuring tool machining method is used for machining of the vapor seal measuring tools.

Description

technical field [0001] The invention relates to a processing method of a steam seal measuring tool. Background technique [0002] The steam seal measuring tool is a special tool for testing the tooth pitch of the steam seal. The current processing technology is difficult to ensure the accuracy of the workpiece. Failure to meet the requirements for use also causes greater losses. Contents of the invention [0003] The invention aims to solve the problem that the accuracy of the existing steam seal measuring tools is difficult to guarantee. [0004] Technical scheme of the present invention is: [0005] A method for processing a steam seal measuring tool, comprising the steps of: [0006] Step 1: Roughly turn each part on an ordinary lathe, each outer circle and end face should be heavy-duty on one side by 3mm, and the inner hole and the tooth surface of the steam seal should be heavy-weight on one side by 3mm; [0007] Step 2: heat treatment, the workpiece is heat treat...
