Embodiment 1

[0040] Such as Figure 1 to Figure 3 As shown, the embodiment of the present invention provides a welding seam reinforcement processing device, which includes a base frame 1, a milling unit, a polishing unit, and a grinding unit arranged between the milling unit and the polishing unit;

[0041] The milling unit comprises a milling cutter 2-1, a milling buffer floating part 2-3, a milling cutter fixed plate 2-4 and a milling driving part 2-2 arranged on the milling cutter fixing plate 2-4; the milling driving part 2-2 and The milling cutter 2-1 is connected to drive the milling cutter 2-1 to rotate; one end of the milling buffer floating part 2-3 is connected to the milling cutter fixed plate 2-4, and the other end is connected to the base frame 1, and the milling buffer floating part 2- 3 is used to drive the milling cutter fixing plate 2-4 to move up and down according to the residual height of the weld to be milled;

[0042] The grinding unit includes a louver wheel 3-1, a ...

Embodiment 2

[0055] The present invention also provides a welding seam processing method based on the above-mentioned welding seam reinforcement processing device, the method includes the following steps:

[0056] Install the base frame 1 on the moving mechanism of the automation equipment, and make the milling cutter 2-1 close to the starting end of the weld seam to be milled

[0057] Adjust the height of the guide adjustment plate 2-5 relative to the milling cutter 2-1, specifically: when the preset weld residual height is high, first loosen the bolt 2-7, and then move the guide adjustment plate 2-5 upwards Tighten the bolt 2-7 until the distance between the limit roller 2-6 and the milling cutter 2-1 is equal to the preset weld residual height. Conversely, when the preset welding seam residual height is low, after loosening the bolt 2-7, move the guide adjustment plate 2-5 downward until the gap between the limit roller 2-6 and the milling cutter 2-1 Tighten the bolts 2-7 after the dis...

Abstract

The invention relates to the technical field of weld joint processing and provides a weld joint excess weld metal processing device and a weld joint processing method. The device comprises a base frame, a milling unit, a polishing unit and a burnishing unit; the milling unit comprises a milling cutter, a milling buffer floating part, a milling cutter fixing board and a milling drive part arrangedon the milling cutter fixing board; the milling buffer floating part is used for driving the milling cutter fixing board to vertically move according to the excess weld metal of a weld joint to be milled; the polishing unit comprises a flap disc, a polishing drive part and a polishing buffer floating part; the polishing buffer floating part is used for driving the polishing drive part to vertically move according to the excess weld metal of the weld joint to be polished; and the burnishing unit comprises a brush head, a burnishing drive part and a burnishing buffer floating part which is usedfor driving the burnishing drive part to vertically move according to the excess weld metal of the weld joint to be burnished. Through the method, super-long weld joints of twenty meters or longer canbe processed continuously without interruption, milling, polishing and burnishing procedures can be finished at a time, and the processing quality can also be ensured.

Description

technical field [0001] The invention relates to the technical field of weld seam treatment, in particular to a weld seam reinforcement treatment device and a weld seam treatment method. Background technique [0002] In the machinery manufacturing industry, the local surfaces of many large-scale mechanical structures need to be finished to meet certain flatness and roughness requirements. At present, the weld reinforcement of aluminum alloy rail vehicle bodies at home and abroad is mainly ground by hand-held electric or pneumatic grinders, angle grinders and other tools, so multiple workers are required to manually perform the steps of milling, grinding, and polishing. Thereby not only labor intensity is big, work efficiency is low, but also can't guarantee the milling, grinding and polishing quality of weld seam surface. Contents of the invention [0003] (1) Technical problems to be solved [0004] The present invention aims to solve the technical problems of high labor...
