A clamshell grab welding equipment

Abstract

The invention relates to a welding device for a clamshell bucket. The welding device comprises a bottom plate base, a shovel fixing device, a jaw plate fixing device, a welding groove clearing device and an overlap flattening device, wherein the shovel fixing device is located on the left side of the bottom plate base and fixedly connected with the bottom plate base, the jaw plate fixing device is located on the right side of the shovel fixing device, the welding groove clearing device is located between the jaw plate fixing device and the overlap flattening device, and the overlap flattening device is fixedly connected with the bottom plate base. The welding device can fix shovels and jaw plates before welding, and the problem of malposition in the welding process due to instable fixation is solved; paint, rust, impurities and other substances at a welding groove can be cleared, the mechanical automation degree is high, and a large amount of labor force is reduced, and the clearing effect is excellent; meanwhile, the welded overlap can be flattened, three-degrees-of-freedom space movement of one translation and two rotations can be realized by means of a flattening grinding head in the overlap flattening process, the movement adjustment is good, and the appearance attractiveness of the bucket is improved.

Description

technical field [0001] The invention relates to the field of grab welding machinery, in particular to clamshell grab welding equipment. Background technique [0002] The grab bucket is a bucket that can be opened and closed by grabbing sand, gravel and various bulk goods. It is a spreader that mainly relies on the opening and closing of two combined buckets on the left and right or multiple jaw plates to grab and discharge bulk materials. According to the classification of the shape, the grab can be divided into a shell-shaped grab and a orange-shaped grab. The former is composed of two complete buckets, and the latter is composed of three or more jaw plates; according to the driving method, it can be divided into hydraulic There are two types of grabs and mechanical grabs. [0003] Welding, also known as welding or welding, is a manufacturing process and technology that uses heat, high temperature or high pressure to join metal or other thermoplastic materials such as plas...

AI Technical Summary

Problems solved by technology

[0004] (1) The bucket and the jaw plate are too large, heavy and irregular in shape, so they are not easy to fix during the welding process, and often cause misalignment during the welding process due to unstable fixation;

[0005] (2) Before welding, it is necessary to clean paint, rust and impurities on the welding groove. Whether the groove is cleaned or not directly affects the quality of welding. At present, manual cleaning is mostly used, which takes up a lot of labor and The cleaning effect is not obvious;

[0006] (3) During the welding process, a large amount of welding slag, waste material and a large number of welding burrs will be produced. After the welding, the welding burrs need to be leveled. However, due to the large amount of heat generated during the welding process, the temperature around the welding joint is very high, which is not easy Manually smooth the welding bump, the existence of the welding bump greatly affects the appearance of the entire grab
