Tubular workpiece synchronous rotating and clamping mechanism and welding system based on visual inspection

Abstract

The invention provides a tubular workpiece synchronous rotating and clamping mechanism and a welding system based on visual inspection. The tubular workpiece synchronous rotating and clamping mechanism comprises a first clamp, a second clamp, a driving mechanism and a sliding rail base. The first clamp and the second clamp are movably arranged on the sliding rail seat, the sliding rail seat extends in the axial direction of the tubular workpiece, and a clamping opening of the first clamp is opposite to a clamping opening of the second clamp in the axial direction of the tubular workpiece; the first clamp and the second clamp are connected with the driving mechanism, and the driving mechanism is used for synchronously controlling the clamping opening of the first clamp and the clamping opening of the second clamp to be switched between the first state and the second state. According to the device, tubular workpieces with different lengths and different pipe diameters can be conveniently clamped, it is ensured that the tubular workpieces synchronously rotate along with an automatic girth welding machine in a horizontal posture, and the girth welding quality is conveniently ensured by conducting visual inspection on the to-be-welded ends of the tubular workpieces before girth welding and recognizing the diameter and pipe wall defects.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a tubular workpiece synchronously rotating clamping mechanism and a welding system based on visual inspection. Background technique [0002] Currently, circular seam welding is usually used for welding tubular workpieces. For example, circular seam welding can be used to weld opposite ends of two steel pipes, or to weld opposite ends of a steel pipe and a tubular end plug. Among them, circular seam welding is aimed at the welding of various circular and circular welds, and the weld formed by welding is a closed circular ring. [0003] In practical application, girth welding is realized by automatic girth welding machine. Automatic circular seam welding machine is a general automatic welding equipment that can complete various circular and circular seam welding. However, for different types of tubular workpieces, the automatic girth welding machine is often unable to automatica...
