Positioning and clamping tooling for assembly and welding of torsion cylinder components of mining dump trucks

Abstract

The invention provides a positioning and clamping tool for assembling and welding a torsion barrel assembly of a mining dump truck. The tool comprises a base plate. First supports used for supporting a torsion barrel and a pair of second supports used for supporting a lifting cylinder sleeve are fixedly arranged on the top face of the base plate, a first positioning reference assembly used for longitudinally fixing the torsion barrel is fixedly arranged on the portion, outside the first supports, of the top face of the base plate, and a second positioning reference assembly used for longitudinally fixing the lifting cylinder sleeve is fixedly arranged outside the second supports. A thrust frame support is further arranged between the first supports and the second supports. The base plate is fixedly provided with a first support supporting assembly used for supporting a first lifting cylinder support and a second support supporting assembly used for supporting a second lifting cylinder support. The tool can achieve one-time clamping and positioning of all components in the torsion barrel assembly, brings convenience to operation, improves the quality of a finished torsion barrel assembly, and effectively reduces errors caused by fixture clamping.

Description

technical field [0001] The invention relates to mechanical manufacturing technology, in particular to a positioning and clamping tool for assembly and welding of a torsion barrel assembly of a mining dump truck. Background technique [0002] Mining dump trucks are key equipment commonly used in open-pit mining and civil engineering sites. They have the characteristics of heavy load and high efficiency. Due to their harsh working environment, they have high requirements for the strength, rigidity and reliability of the frame. [0003] The frame of a mining dump truck is generally welded by steel plates, castings and steel pipes. The torsion tube assembly set in the middle is an important part of the frame. It not only connects and supports other important parts such as cargo boxes, rear axles, etc. , but also bear the weight of the vehicle itself and the dynamic load of the vehicle. figure 1 is a schematic diagram of the structure of the torque cylinder assembly; figure 1 A...

AI Technical Summary

Problems solved by technology

[0004] Depend on figure 1 It can be seen that the shape of the first lift cylinder support 13 and the second lift cylinder support 14 in the torque cylinder assembly is irregular, and they are three-dimensional after assembly. Therefore, in the prior art, it is necessary to place each component in the Welding is performed on the operating platform and fixed with steel plates and bolts one by one. Not only is the operation cumbersome, but also the positioning is inaccurate, which affects the quality of the final torque tube assembly.
