Front frame positioner

Abstract

The invention discloses a front frame position changing machine which comprises a mounting seat. A motor and an L-shaped supporting arm are arranged in the mounting seat, and a through hole is formed in the vertical part of the L-shaped supporting arm. An output shaft of the motor penetrates through the through hole to be connected with the L-shaped supporting arm, and a DC motor is fixedly mounted on the horizontal part of the L-shaped supporting arm. A rotating table is connected to the output end of the DC motor, a plurality of internal threaded grooves are formed in the rotating table, the internal threaded grooves are annular bodies which are formed by a plurality of adjacent through holes, and the internal threaded grooves radiate in the radial direction along the circle center of the rotating table. The front frame position changing machine further comprises pressing plates, the pressing plates are connected with the internal threaded grooves through bolts, and a damping structure is arranged on the through hole. When the motor drives the L-shaped supporting arm to rotate, radial run-out can happen to the output shaft of the motor, so that the L-shaped supporting arm moves up and down. The damping structure is mounted on the through hole, the output end of the motor penetrates through the damping structure so that the radial run-out influence can be removed, the stability of a front frame in the welding process can be further guaranteed, and the welding quality of the front frame is improved.

Description

technical field [0001] The invention relates to a welding auxiliary tool, in particular to a front frame positioner. Background technique [0002] Welding technology has been widely used in light and heavy industries such as aviation and aerospace. The quality of welding directly affects the quality of products and the performance of the whole machine. Therefore, improving welding technology and improving welding quality play an important role in industrial modernization. Among them, improving the level of welding mechanization and automation and realizing the modernization of welding technology and equipment are an important aspect of improving welding quality. Generally speaking, in welding production, there will be When encountering welding displacement and selecting a suitable welding position, in response to this actual need, there are many positioners on the market, which can rotate the various welds of the workpiece to be welded to the best position, thereby avoiding ...

AI Technical Summary

Problems solved by technology

The positioner can make the weld seam on the workpiece be welded in the ideal boat-shaped position or flat welding position, which improves the welding efficiency and reduces the labor intensity; however, in the actual operation process, the weld seam is often Repeated welding or missing welding occurs. The reason is that under the long-term working load, the rotation of the motor is often unstable, sometimes fast and sometimes slow. Whether it is manual welding or mechanical intelligent welding, the solder joints are easy to gather together or the intervals are very small. A long distance, which will cause repeated welding or missing welding of the weld seam
