A New Type of Compressor for Welding Oval Flanges

Abstract

The invention discloses a novel pressing device for welding of an elliptic flange plate. The novel pressing device comprises a pressing rod placed vertically, wherein a stop ring is arranged at the lower end of the pressing rod; the upper end of the pressing rod is connected with a base plate placed horizontally; a cross-shaped sliding groove is formed in the base plate; two movable sliding blocks are mounted on the sliding groove, and are connected with the two ends of a rotary rod respectively; a plurality of threaded holes are evenly formed in the rotary rod; the middle of the rotary rod is hinged to one end of a crank through a pin shaft; the lower part of the other end of the crank is rotationally connected with the base plate in the center of the cross-shaped sliding groove; a second handle is fixedly arranged at the upper part of the other end of the crank; any one threaded hole in the rotary rod can be in threaded connection with the threaded rod; a first handle is arranged at the upper end of the threaded rod; and a pressing block is arranged at the lower end of the threaded rod. By employing the elliptic trammel principle, the pressing block of the novel pressing device can form an elliptic motion track, and the purpose of effectively pressing the elliptic flange plate is reached. Elliptic tracks having different parameters can be formed as required; the positioning is reliable and precise; the structure is simple; and the operation is convenient.

Description

Background technique [0001] Oval steel pipe has beautiful appearance and excellent structural performance, and is widely used in construction and other industries. If they are connected for use, they are generally connected by flanges at the ends. With the wide application of robots in the field of welding, in order to ensure welding requirements and improve productivity, some manufacturers are currently trying to replace manual welding with robotic hands. After the flange plate and the pipe body are aligned, a compression device is required to be compressed before welding, but a simple and practical compression device has not been developed yet. Contents of the invention [0002] In order to meet the user's compaction requirements for the welding of oval steel pipes and oval flanges, the invention provides a new type of compactor for welding oval flanges. [0003] The technical solution adopted by the present invention to solve its technical problems is as follows: [00...
