Description

[0002] A trailer is a vehicle towed by a truck but without its own power drive. It consists of a truck (or tractor-trailer / forklift) and one or more trailers. The truck and tractor are the driving sections of the trailer, called the tractor unit, and the driven sections towed by the tractor unit are called trailers. The tensioner, an indispensable component for loading cargo onto a trailer, tightens the steel cables binding the cargo, thus securing the cargo, tarpaulins, etc. Its production requires welding.

[0041] Working principle:

[0042] When welding is required on the rope tensioner, the rope tensioning drum is first fixedly placed on the workpiece placement seat 32, and the fine teeth are fixedly placed on the workpiece gear support plate 33. The indexing motor 35 is started, and after rotating a certain angle, it stops, thereby driving the indexing plate 31 to rotate a certain angle. When the workpiece placement seat 32 with the workpiece placed on it rotates to the bottom of the welding torch barrel 221, the welding torch barrel 221 rotates under the action of the steering motor 223. At this time, the welding torch head set at the bottom of the welding torch barrel 221 rotates circumferentially to weld the workpiece. When the steering motor 223 is started, the clamping cylinder 2210 is started at the same time. The extension rod of the clamping cylinder drives the clamping top plate 2211 to extend forward and hold the workpiece in place to prevent the workpiece from moving during welding.

[0043] After welding, the clamping cylinder 2210 retracts the telescopic rod, bringing back the clamping top plate 2211, and no longer squeezing and fixing the workpiece. The welded workpiece leaves the bottom of the welding gun barrel under the rotation of the indexing plate. At this time, the workpiece placement seat 32 rotates to the position of the unloading cylinder 38, the unloading cylinder 38 starts, driving the telescopic rod to extend. At the same time, the telescopic rod drives the unloading top plate 39 to move towards the unloading through hole on the workpiece placement seat 32, pushing out the welded workpiece.

[0044] In the above embodiments and working principles, the movable component allows for convenient vertical and horizontal movement of the welding torch. Simultaneously, the wire feeder delivers the welding wire to the torch head in real-time for welding the workpiece. Furthermore, the rotating torch barrel assembly facilitates rotation of the torch barrel, enabling the torch to perform circular welding around the workpiece. The indexing plate divides the workpiece into equal sections, and the stepping motor of the indexing motor rotates the workpiece by a fixed angle with each rotation, achieving automatic feeding. The clamping cylinder further enhances the welding torch's ability to... To facilitate workpiece fixation during welding and prevent workpiece shaking during the welding process; the set-up unloading component allows for automatic unloading of the welded workpiece; in addition, a light-blocking curtain bracket is fixed on the main unit base for easy hanging of the light-blocking curtain to prevent light from damaging the operator's eyes during welding; through the set-up PLC control box, the actions of the indexing motor, clamping cylinder, steering motor, and unloading cylinder can be programmed according to actual needs to achieve automated welding; at the same time, a foot switch can be used to start all programs at once, thereby achieving semi-automated operation.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
