Abstract

The invention discloses a seam tracking device with double tracking probes, and relates to a seam tracking device. The seam tracking device comprises a box body, bolt connecting blocks, displacement sensors, guide rod connectors, sensor mounting flanges, an upper box cover, springs, adjusting bolts, spring hooks, probe fixing bolts, the tracking probes, guide rods, a cantilever beam, a rolling bearing and a shaft sleeve, wherein the cantilever beam is arranged on the inner wall of the box body; two guide rods are arranged on the cantilever beam; through holes are formed in the centers of the two guide rods; two springs are arranged on each of the left and right parts of the guide rods; and the tail ends of the springs are connected to the adjusting bolts through the spring connecting blocks and the spring hooks. Inclination angles of the guide rods are adjusted by screwing and unscrewing left and right nuts, so that the two tracking probes at the tail ends of the two guide rods cling to the inner wall of a seam. The displacement sensor connected to the upper ends of the guide rods is used for processing deviation information through a singlechip microcomputer, and controlling an executor to correct a deviation between the trajectory of a welding gun and the seam, so that the tracking accuracy and reliability are improved, the working efficiency is improved, and the cost is reduced.

Description

technical field

[0001] The invention relates to a seam tracking device, in particular to a seam tracking device with double tracking probes. Background technique

[0002] The existing narrow-gap seam tracking methods generally include laser scanning, computer image recognition and so on. The disadvantage is that the principle is more complicated, and it is more difficult to repair once a fault occurs. Moreover, the anti-interference ability is poor and the cost is high. Contents of the invention

[0003] The object of the present invention is to provide a double-tracking probe weld seam tracking device, which adopts the tracking method of mechanical probes and sensors, does not need to replace the mechanical probes according to the shape of the weld seam, can be used in conjunction with welding tools, and can Overcome the influence of the defect of the narrow gap weld track on the welding accuracy, and improve the welding quality.

[0004] The purpose of the present inv...
