Detecting, milling and polishing equipment for workpiece welding seams

Abstract

The invention provides detecting, milling and polishing equipment for workpiece welding seams, and belongs to the field of milling of large-allowance welding seams. The detecting, milling and polishing equipment comprises a manipulator, a polishing part, a workpiece detection assembly, a milling assembly, an abrasive belt polishing assembly and a chain rotating assembly, wherein the polishing part is connected to the head end of a manipulator body and used for polishing the surfaces of workpieces under the driving of the manipulator body so as to control the removal depth of welding seams, and the polishing part comprises a polishing mechanism and a protection mechanism; the polishing mechanism comprises a rack; the workpiece detection assembly is used for detecting the surfaces of the workpieces; the milling assembly is used for milling the surfaces of the workpieces according to detection results of the workpiece detection assembly; the abrasive belt polishing assembly is used for polishing the surfaces of the workpieces according to the detection results of the workpiece detection assembly; and the chain rotating assembly is used for driving the abrasive belt polishing assembly in real time according to the detection results of the workpiece detection assembly. By means of the treatment scheme, fine milling and polishing are conducted on the large-allowance welding seams in a targeted mode.

Description

technical field [0001] The invention relates to the field of milling of large margin welds, in particular to a workpiece weld inspection, milling and grinding equipment. Background technique [0002] In large-scale manufacturing industries such as high-speed rail, heavy industry and shipbuilding, there are a large number of large-scale component welding. Although the welding of large components has been gradually automated, due to the processing tolerances of large components, clamping positioning errors, welding thermal deformation and unstable welding processes, etc., there are large gaps in the weld position and margin after welding of large components. deviation.

Although the welding of large components has been gradually automated, due to the processing tolerances of large components, clamping positioning errors, welding thermal deformation and unstable welding processes, etc., there are large gaps in the weld position and margin after welding of large components. deviation

At present, for this type of weld, ordinary special-purpose equipment is not competent, and it mainly relies on manual grinding of related welds.

[0003] However, manual grinding has disadvantages such as large grinding workload, harsh environment, low efficiency, difficult to guarantee product quality, and poor product consistency; even if the cylinder floating method is forced to mill the weld seam, the equipment generally needs to be installed on the component and then the component Milling and grinding, the grinding parameters are difficult to control (grinding force, grinding disc wear interpolation and grinding disc contact pressure, etc.) and the grinding allowance of the large margin weld itself is inconsistent, resulting in poor grinding quality and consistency, and finally still needs to be done manually lots of tinkering
