The circular tube welding seam detecting and positioning mechanism solves the problem of low detecting efficiency of an existing welding seam detecting device. The circular tube welding seam detecting and positioning mechanism comprises a base, and a worktable and a positioning seat are arranged on the base; a feeding bin is provided with a bottom plate capable of conveying a workpiece, the positioning seat is provided with a limiting groove for allowing the workpiece to be placed, and the workpiece can rotate in the limiting groove; the base is provided with a rotating motor, a proximity switch and a clamping air cylinder, and the rotating motor is arranged on one side of the workpiece; one end of the rotating motor is provided with a rotating groove for allowing the end part of the workpiece to be embedded, and the clamping air cylinder can push the workpiece until one end of the workpiece is embedded in the rotating groove; and the feeding bin is provided with a sensor, when the approaching switch detects that the workpiece is located in the limiting groove, the rotating motor can be driven to drive the workpiece to rotate, and the sensor can conduct welding seam detecting on the workpiece. The circular tube welding seam detecting and positioning mechanism can improve the efficiency of workpiece welding seam detecting.

Description

technical field [0001] The invention belongs to the technical field of processing equipment, and relates to a circular pipe welding seam detection and positioning mechanism. Background technique [0002] With the improvement of industrial automation level, there are more and more applications of manipulators for loading and unloading of workpieces. However, when round pipes have angle requirements for welds during arc punching of elbows, welds should be installed on the feed bin. The detection and positioning mechanism can facilitate the identification and positioning of the weld seam, and it is convenient for the manipulator to take the pipe fittings to determine the direction of the weld seam. [0003] Therefore, people have developed a variety of pipe fitting weld detection devices: [0004] For example, Chinese patent application (patent application number: 201410168380.X) discloses a polygonal tube inscribed weld detection device, which discloses a sensor bracket for d...

Problems solved by technology

[0005] Although the above structure realizes the detection of welds to a certain extent, in the detection process, multiple welding detection sensors are used, so that the whole detection process has more data, and the observation is more responsible. The manipulator needs to perform multiple screenings and judgment, resulting in low efficiency of pipe fitting weld detection
