Automatic seaming device of cylinder straight seam welding machine

Abstract

The invention discloses an automatic seaming device of a cylinder straight seam welding machine. The automatic seaming device comprises a base, a sliding plate, a sliding plate drive mechanism, a clamp mechanism supporting piece, a sliding plate limiting piece, a pin roller and a clamp mechanism. The clamp mechanism supporting piece can slide front and back along the base. A first sliding groove is formed in the lower portion of the clamp mechanism supporting piece. The position, corresponding to the first sliding groove, of the sliding plate limiting piece is provided with a second sliding groove. The sliding plate penetrates the first sliding groove and the second sliding groove and can move left and right along the first sliding groove and the second sliding groove. The second sliding groove is used for limiting the front-back movement of the sliding plate. Third sliding grooves are obliquely formed in the two ends of the sliding plate, the pin roller penetrates the third sliding grooves, the pin roller is connected with the clamp mechanism supporting piece and used for driving the clamp mechanism supporting piece to slide front and back, and the sliding plate drive device is connected with the sliding plate and used for driving the sliding plate to slide left and right. The clamp mechanism comprises a clamp installing mechanism capable of being adjusted front and back, and a driven roller type clamp arranged on the clamp installing mechanism. The clamp mechanism is arranged on the clamp mechanism supporting piece through the clamp installing mechanism.

Description

technical field [0001] The invention relates to the field of cylindrical straight seam welding machines, in particular to an automatic seam closing device for cylindrical straight seam welding machines. Background technique [0002] Straight seam welding machine (Straight seam welding machine) is an automatic welding equipment that realizes the automatic completion of the straight line weld of the welding workpiece through automation and mechanization. Straight seam welding machine is also called straight seam automatic welding machine, longitudinal seam automatic welding machine, which is a kind of automatic welding machine. It can replace labor in large quantities, greatly improve production efficiency and welding quality, reduce labor costs, and improve the working environment of welders. For example, the shell corner seam welding of large transformers, the straight seam welding of large cylinders, the straight seam welding of solar water heater cylinders, the straight s...

AI Technical Summary

Problems solved by technology

The existing synchronous mechanism is expensive and takes up a lot of space; at present, the seam clamps of the unmanned automatic straight seam welding machines produced internationally and domestically all use imitation block clamps (imitation circular arc shape), which have the following defects: 1. In the production of multi-variety and small-batch products, when the diameter changes greatly, it is necessary to replace the profiling clamping block, which increases labor intensity and downtime, and reduces production efficiency; There will be relative sliding between the cylinder and the imitation clamping block, and the sliding friction coefficient between the clamping block and the cylinder is large (the resistance is very large), resulting in poor seam accuracy and forming, and affecting welding quality
