Titanium alloy thick-wall spherical head scalloped petal longitudinal seam groove milling and fixing device and machining method

Abstract

The invention belongs to the field of titanium alloy thick-wall spherical head scalloped petal longitudinal seam groove milling, and particularly relates to a titanium alloy thick-wall spherical head scalloped petal longitudinal seam groove milling fixing device and a machining method. The fixing device comprises a bottom supporting base and a vertical supporting frame, at least two sets of bottom clamping bases capable of fixedly clamping the large end of the scalloped segment part are installed on the bottom supporting base, and the bottom clamping bases are provided with bottom adjusting mechanisms. The vertical supporting frame is provided with at least two sets of top clamping bases capable of fixedly clamping the small ends of the scalloped segment parts, and the top clamping bases are provided with top adjusting mechanisms. And the height adjusting mechanism is used for adjusting the height of the scalloped segment part. According to the device, the scalloped segment parts are easy to install, position and fix, and positioning is accurate; batched scalloped segment parts of the same specification are convenient to machine and position, the machining efficiency is obviously improved, and efficient and high-precision milling machining of longitudinal seam grooves of the titanium alloy thick-wall spherical end socket scalloped segment parts is facilitated.

Description

technical field [0001] The invention belongs to the field of bevel milling of longitudinal seams of melon petals of titanium alloy thick-walled spherical heads, in particular to a device and method for milling longitudinal seams of melon petals of pressure-bearing heads of deep overseas pressure high-pressure titanium alloy equipment. Background technique [0002] The conventional pressure vessel melon flap splicing head can meet the design requirements after the melon flap is formed and welded in accordance with the corresponding standards. Usually, the melon flap can be spliced, welded, and According to inspection requirements, mechanical processing is generally not used for bevel finishing, and technologies such as wholesale and retail, high-precision, convenient processing and process control methods for the longitudinal seam of the spherical head and melon petals need to be overcome. [0003] The spherical head of titanium alloy thick-walled external pressure and high-p...

AI Technical Summary

Problems solved by technology

[0004] In view of the fact that there are certain shape and size deviations in the results of compression molding and heat treatment of titanium alloy spherical head and melon petal parts, and the melon petal parts have a spatial structure, there are many problems in clamping, positioning, and margin distribution before machining. Great technical difficulty, especially the urgent demand for processing quality and processing efficiency of mass-produced melon petal parts, so a titanium alloy thick-walled spherical head melon petal longitudinal seam bevel milling fixture and method are needed in this field, especially Provide a high-precision and high-efficiency milling method for the groove of the longitudinal seam of the melon petal of the titanium alloy thick-walled spherical head
