Embodiment

[0019] Such as figure 1 As shown, the method for processing and positioning elbow parts of the present invention includes the following sequential steps:

[0020] 1) Take the elbow 1 and clamp it on the elbow positioning tool 2, and make the flange surface A3 and flange surface B4 of the two ports of the elbow 1 face outward horizontally, and keep the flange surface A3 and flange surface B4 in line with the horizontal plane vertical;

[0021] 2) With the flange surface A3 as the reference, use the probe to detect and correct the center reference aa of the flange surface A3;

[0022] 3) Use the corrected flange surface A3 center datum to convert the theoretical flange surface B4 center datum ba;

[0023] 4) Use the converted theoretical flange surface B4 center reference ba as a reference, use the probe to detect the flange surface B4 center reference bb, and calculate the difference between the detected flange surface B4 center reference bb and the theoretical flange surface...

Abstract

The invention discloses a positioning method for elbow parts and provides a machining and positioning method for the elbow parts. According to the machining and positioning method for the elbow parts, the positioning method for the elbow parts is simple and high in positioning accuracy and efficiency, and the technical problems that the positioning accuracy is low, defective products are prone to be produced, and consequently the rejection rate of the parts is increased during machining of the elbow parts in the prior art are solved. The machining and positioning method for the elbow parts generally includes the steps that firstly, center data of flanges at the two ends of an elbow are detected out through a probe; then the data are compared and compensated; the compensated data are verified; and finally, procedural machining is performed through the compensated data.

Description

technical field [0001] The invention relates to a positioning method for bent pipe parts, in particular to a simple and accurate processing and positioning method for bent pipe parts. Background technique [0002] Accurate positioning is required when processing bent pipe parts, especially for casting bent pipe parts. The traditional positioning method is to clamp after scribing. Due to the increase of scribing process, not only the labor cost is increased, but also the production efficiency is low. The processing of existing casting elbow parts is generally based on the shape positioning. Due to the large deviation of the casting shape and size, the clamping error is large, so many defective products are produced in the actual production of the parts, such as the thickness of the flange after processing. Unevenness, when the parts are used for assembly, the outer circle of the flange is misaligned, the center distance is out of tolerance, and the deviation of the flange hol...
