Embodiment Construction

[0025] The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.

[0026] Such as Figure 1-2 As shown, a precision machining method for a flame stabilizer includes the following steps:

[0027] Step 1, argon arc welding precision casting and plug 11;

[0028] Step 2, milling the ear seat, removing the ear seat allowance, and ensuring the wall thickness and position of the ear seat;

[0029] Step 3, drilling and processing the ear seat hole 12 to ensure the position of the ear seat hole 12;

[0030] Step 4, spraying a high temperature resistant coating on the surface of the part;

[0031] Step 5, reaming, remove the 12 margins of the ear seat hole, and ensure the precise ear seat hole size;

[0032] Step 6, according to the diameter and arc radius of the oil delivery pipe 2 and the arc length of the annular channel of the stabilizer, a detection device is manufactured, and the detection device...

Abstract

A precision machining method and a detection device for a flame stabilizer, including processes such as argon arc welding and high-temperature coating spraying, and after each step of heat treatment process, the shaping and correction of the parts are carried out, and finally the annular channel is carried out by the detection device. Detection, the invention fundamentally solves the influence of the spraying high temperature coating process on the size of the precision ear seat hole, and the precision castings are machined after the high temperature thermal process such as the high temperature coating to remove the allowance, which improves the delivery of the precision ear seat hole size of the parts. The pass rate of the annular channel can be effectively detected, the channel interference points can be removed in time during the product processing process, the product technical requirements and assembly requirements are guaranteed, the product quality is stable, and the consistency is good. It is popularized and used in various parts that need to be processed by annular channel parts.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a precision processing method and a detection device for a flame stabilizer. Background technique [0002] Such as figure 1 As shown, it is a partial schematic diagram of the processed parts. The welded assembly of thin-wall precision castings and sheet metal parts presents a complex spatial distribution due to the structure of the parts, the main body wall is thin, there are many welded joints, and the precision of the machined ear seat holes is high. Finally, Parts are sprayed with high-temperature coating, and the high spraying temperature leads to large deformation after coating, resulting in unqualified precision hole size and unqualified precision ear seat hole processing when the parts are delivered to the warehouse, which is likely to cause interference in the later assembly process and poor assembly consistency . This type of stabilizer annula...
