specific Embodiment approach 1

[0048] Specific embodiment 1: A method for inspecting marking lines of round and multi-angle shape forgings, which includes the following steps:

[0049] Step 1: Grind and burr the forgings that meet the marking requirements, paint the forgings with colored dye liquid, clamp the forgings by combining the square box and the top or by using the top alone, and fix the forgings on the marking inspection platform superior;

[0050] Step 2: Calibrate and level the workpiece with a height gauge, and draw a reference line on the forging according to the drawing;

[0051] Step 3: Fix the workpiece on the universal indexing head on the platform with the inner and outer jaws of the workpiece shape. When the jaws cannot be assembled, punch the center of the workpiece and assemble it with a special assembly axis;

[0052] Step 4: Calculate all the indexing data according to the universal indexing head used, and record the number of revolutions of the required handle;

[0053] Step 5: Rotat...

specific Embodiment approach 2

[0057] Specific embodiment two: the colored dye in the step one is gentian violet dye.

[0058] Other implementation manners are the same as the specific implementation manner 1.

[0059] Other implementation manners are the same as the specific implementation manner 1.

specific Embodiment approach 3

[0060] Embodiment 3: The reference line in step 2 includes a height reference line, a circle center and a dimension line.

[0061] Other implementation manners are the same as the specific implementation manner 1.

Abstract

The invention relates to the field of outline dimension lineation detection of aluminum and aluminum alloy die forgings, and magnesium and magnesium alloy die forgings, in particular to a lineation inspection method for round and multi-angle outline forgings. The method comprises the following steps of: calculating all indexing data according to a universal indexing head during indexing calculation, and recording the number of revolutions of a required handle, and sequentially rotating the handle to a required degree, calculating according to the shaking turns of the handle of the universal dividing head, the equal score of the dividing head and the equal score of the workpiece, and drawing a required dimension line by using a height gauge. According to the invention, the method thoroughly changes the original method for checking such forgings by scribing, and effectively overcomes the complicated and cumbersome operation; some auxiliary accessories are designed and processed by using the original idle equipment, so that the cost investment is low, and the effect is quick; and the checking method for forgings with similar shapes is developed and extends, under the state that the workshop quality inspection task is heavy and the requirement is high, the lineation task of the die forgings of various specifications is completed, and a user identifies and accepts the inspection result.

Description

technical field [0001] The invention relates to the field of line-scribing detection of the external dimensions of die forgings of aluminum, aluminum alloys, magnesium, and magnesium alloys, in particular to a line-scribing inspection method of circular and multi-angle external forgings. Background technique [0002] Die forgings of aluminum and aluminum alloys, magnesium and magnesium alloys are widely used in civil and military aerospace fields, and the scribing detection of die forgings is particularly important. It cannot meet the existing precision requirements, and the operation steps are complicated. [0003] The line marking inspection process is a key link in the quality inspection of aluminum and magnesium alloy forgings. It mainly involves the inspection of forging dies, the line marking inspection of free forgings, die forgings, forging rings and other products, and the guidance and inspection of mold repairing. [0004] Work object forgings are roughly divided ...
