Problems solved by technology

[0002] The JLG company of the United States uses the connecting parts between the arms of the single-arm lifting platform. Due to its high degree of difficulty in mechanical processing, JLG company has found 9 suppliers in China for trial production. Due to the use of conventional mechanical processing methods, the workpiece samples provided Or because the welding deformation and stress are greater than the requirements, or because of the poor concentricity of the concentric holes, all failures
[0003] Therefore, there are above-mentioned inconveniences and problems in the processing method of the connecting parts between the arms of the known lifting platform.

Embodiment Construction

[0037] The present invention will be further described below in conjunction with embodiment and accompanying drawing.

[0038] see now figure 1 and figure 2 , figure 1 It is a front view of parts assembled in the embodiment of the present invention, figure 2 for figure 1 side view. The method for processing the connecting parts between the arms of the lifting platform of the present invention is characterized in that it comprises the following steps:

[0039] a. Cutting

[0040] According to the requirements of the drawings, select Q420 or Q550 steel plates. Laser cutting is used for steel plates with a thickness of less than 12mm, and high-precision plasma cutting is used for plates with a thickness of more than 12mm; the bent parts are bent by a CNC bending machine to make the bent parts reach 105 o Radian, processed into various special-shaped parts including side plates and pipes; when the steel plate is made by laser cutting, a margin of 2mm is placed in the direc...

Abstract

A processing method for an inter-arm connection component of a lifting platform is characterized by mainly comprising following steps a, feeding; b, assembling; c, welding; thermally treating; e, rectifying; f, machining and g, detecting. The processing method for the inter-arm connection component of the lifting platform has the advantages of being reasonable in processing step design, simple to operate, capable of using high scientific equipment to process, high in component processing accuracy and capable of providing examples for processing components with high difficulty coefficient.

Description

technical field [0001] The invention relates to a processing method for mechanical parts, in particular to a processing method for connecting parts between arms of a lifting platform. Background technique [0002] The JLG company of the United States uses the connecting parts between the arms of the single-arm lifting platform. Due to its high degree of difficulty in mechanical processing, JLG company has found 9 suppliers in China for trial production. Due to the use of conventional mechanical processing methods, the workpiece samples provided Or because the welding deformation and stress are greater than the requirements, or because of the poor concentricity of the concentric holes, all of them fail. [0003] Therefore, there are above-mentioned inconveniences and problems in the known processing method of the connecting parts between the arms of the lifting platform. Contents of the invention [0004] The object of the present invention is to propose a processing metho...
