Simple mechanism for detecting and centering arm frame workpiece and detecting and centering method

Abstract

The invention discloses a simple mechanism for detecting and centering an arm frame workpiece. The simple mechanism for detecting and centering the arm frame workpiece comprises a main cross bar, a support, a base, detecting plates and a guiding device fixed on the main cross bar, wherein the main cross bar is horizontally placed, scales are uniformly carved on the surface of the main cross bar, the zero scale is formed in the middle, and readings are increased in sequence towards two sides, the main cross bar is fixed on the base by the support, and the detecting plates comprise a left detecting plate and a right detecting plate which are fixed on sliding seats, are respectively positioned on left and right sides of the zero scale of the main cross bar and slip on the main cross bar to and fro by the sliding seats. By the simple mechanism for detecting and centering the arm frame workpiece and a detecting and centering method, the workpiece can be detected in real time when adjusted, is not required to be subjected to secondary clamping and is convenient to assemble and disassemble, the detecting time is greatly shortened, and production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of detection and alignment, in particular to a simple detection and alignment mechanism and a detection alignment method for boom-like workpieces. Background technique [0002] Boom-type workpieces are large and super-long welded parts, and the deformation after welding is irregular. Before each processing, it is necessary to check whether the workpiece has machining allowance and whether the workpiece is placed in the center, and needs to be quickly loaded and unloaded. The conventional inspection is to use the scale to directly measure the alignment or use the scribing tool to detect the alignment. Although it can meet the requirements, it generally takes two hours to detect a workpiece, and after each adjustment, it needs to be re-inspected, which is very efficient. Low, seriously restricting the production progress. Chinese patent CN 201046892Y discloses a crane jib arc centering and positioning device...
