Automatic milling and grinding machine for welding bead machining and using method

Abstract

The invention discloses an automatic milling and grinding machine for welding bead machining and a using method, and relates to the technical field of welding bead machining. The automatic milling andgrinding machine comprises a workbench, a power fixing plate is fixedly arranged on one side of the bottom of the workbench, a power transverse-moving assembly is installed on the inner side of the power fixing plate, a lifting assembly is arranged on the inner side of the power transverse-moving assembly, a grinding power set is arranged on one side in the lifting assembly, and a milling power set is arranged on the other side in the lifting assembly; and the workbench comprises a working plate, a first steel channel is vertically arranged on one side of the working plate, a second steel channel is horizontally arranged on the inner side of the upper end of the first steel channel, air cylinder supporting plates are fixedly arranged on the two sides of the bottom of the second steel channel correspondingly, clamping air cylinders are installed on the side walls of the air cylinder supporting plates, and welding bead base plates are arranged at the bottoms of the clamping air cylinders. According to the automatic milling and grinding machine for welding bead machining and the using method, the problems that in welding bead machining in the prior art, a handheld grinding machine isgenerally adopted to manually remove a welding bead, or a belt sander is adopted to grind the welding bead, the efficiency is low, and the labor intensity is high are solved.

Description

technical field [0001] The invention relates to the technical field of weld bead processing, in particular to an automatic milling machine for weld bead processing and a usage method. Background technique [0002] Welding bead, metal welding, a single weld seam formed by each deposition, through the inspection of the welding bead, we can know the selected welding current and electric undercut; the arc is too long, the amount of filler metal is too much, and it overflows to the base metal , resulting in overflow, the welding sequence of each weld in the metal welded joint is different, resulting in different residual stress, according to the welding sequence shown in the figure, the residual stress is the smallest. [0003] The existing weld bead processing generally uses a hand-held grinder to manually remove the weld bead, or uses an abrasive belt machine to smooth the weld bead, which is low in efficiency and labor-intensive. Therefore, the present invention proposes an au...

Problems solved by technology

[0003] The existing weld bead processing generally uses a hand-held grinder to manually remove the weld bead, or uses an abrasive belt machine to smooth the weld bead, which is low in efficiency and labor-intensive. Therefore, the present invention proposes an automatic milling machine for weld bead processing. The milling machine and its usage method can solve the above problems. The device mills the weld bead first and then grinds it. The two processes are processed continuously on the same machine, which reduces labor intensity and loss of production materials, and controls the feed rate of the cutter head to achieve good results. surface finish
