Description

Technical Field

[0001] The utility model relates to the technical field of laser pipe welding machines, and particularly relates to a full-automatic laser pipe welding machine. Background Technique

[0002] Welding, also known as fusion welding, is a manufacturing process and technology for joining metals or other thermoplastic materials such as plastics by means of heating, high temperature or high pressure. There are many energy sources for modern welding, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasonic waves. In addition to being used in factories, welding can also be carried out in various environments, such as in the wild, underwater, and in space. Currently, for pipes, a full-automatic laser pipe welding machine is generally used for processing operations.

[0003] For example, in a Chinese authorized patent, a pipe welding machine with high safety, with the publication number CN215546619U, includes a welding mechanism and a feeding mechanism. The steel coil is sent to the coil welding pipe in the welding mechanism through the feeding mechanism. The retainer provided on the coil welding pipe clamps the steel coil, the pressing roller group in the feeding mechanism presses the steel coil, the controller controls the stepping motor to drive the coil welding pipe to rotate, and at the same time, the ball screw drive mechanism drives the coil welding pipe to move. At the same time, the laser welding head starts welding. The grinding device grinds the welded point after welding on the right side of the laser welding head, and the blowing device blows away the grinding dust. The housing provided on the base in the welding mechanism can prevent the arc light radiation during welding from causing damage to the operator. The utility model can effectively prevent the arc light radiation during welding from causing harm to the operator through the protection device, improve the production safety of the enterprise, and reduce the risk of harm.

[0004] When the above traditional pipe welding machine is used, it presses and feeds through the pressing rollers. However, when welding small-sized pipes, the distance between the upper and lower pressing rollers is too large, which easily causes the pipe to fall off from them. When the pressing rollers rotate for feeding, it is easy to cause the pipe to roll in place, resulting in the problem of inability to feed. Content of the Utility Model

[0028] Embodiment

[0029] Refer to Figures 1-6 As shown in the figure, a fully automatic laser pipe welding machine includes a fuselage 1. A feeding plate 211 is fixed at the rear end of the fuselage 1. Four groups of brackets 212 symmetrically distributed in the front, rear, left, and right directions are fixed at the top of the feeding plate 211. A first conveying roller 213 is rotatably connected between every two adjacent lateral brackets 212. The top of the fuselage 1 is connected to a connecting frame 216 through an elastic mechanism. A second conveying roller 214 corresponding to the first conveying roller 213 is rotatably connected to the inner wall of the connecting frame 216. The second conveying roller 214 and the first conveying roller 213 are respectively distributed up and down, and can press the upper and lower ends of the pipe. A plurality of grooves 215 are formed on the outer walls of the first conveying roller 213 and the second conveying roller 214. The pipe is located between the upper and lower grooves 215. The setting of the grooves 215 can achieve the purpose of limiting, avoiding the rolling and falling off of the pipe. The setting of multiple grooves 215 can insert multiple pipes, achieving high-efficiency pipe welding processing efficiency. Under the action of the elastic mechanism, the second conveying roller 214 is continuously pressed down, thereby increasing the friction force with the pipe, avoiding the problem of idling of the first conveying roller 213 and the second conveying roller 214, and ensuring that the pipe can be stably horizontally conveyed into the fuselage 1. The first conveying roller 213 and the second conveying roller 214 can be made of silica gel material, having a rough surface physical property, which can better avoid the falling off of the pipe.

[0030] The elastic mechanism includes a mounting plate 220, a fixed cylinder 221, a movable rod 222, and a spring 223. The mounting plate 220 is fixed at the rear end of the fuselage 1. The fixed cylinder 221 is fixed at the bottom of the mounting plate 220. The movable rod 222 fixed to the top of the connecting frame 216 is slidably connected to the inner wall of the fixed cylinder 221. The movable rod 222 is connected to the inner wall of the fixed cylinder 221 through the spring 223. By pulling up the connecting frame 216, the movable rod 222 is inserted into the fixed cylinder 221, and the spring 223 is driven to be compressed. After releasing the connecting frame 216, under the elasticity of the spring 223, the connecting frame 216 and the second conveying roller 214 can be driven to rebound and achieve the pressing purpose. An opening groove 225 is formed on the outer wall of the fixed cylinder 221. A pushing plate 224 corresponding to the opening groove 225 is fixed on the outer wall of the movable rod 222. The setting of the pushing plate 224 and the opening groove 225 can facilitate the up and down movement of the connecting frame 216 and improve the comfort of the device operation.

[0031] The outer walls of the two groups of first conveying rollers 213 are connected by a transmission mechanism. A first motor 217 is installed on the outer wall of any group of brackets 212. The output end of the first motor 217 is connected to any group of first conveying rollers 213. By turning on the first motor 217, the two groups of first conveying rollers 213 can be driven to rotate synchronously under the transmission mechanism, thereby achieving the purpose of conveying loading or unloading, and using it more efficiently.

[0032] The transmission mechanism includes a belt 219 and two sets of pulleys 218. The two sets of pulleys 218 are rotatably connected to the outer wall of the same side bracket 212 and are fixedly connected to the first conveying roller 213. The two sets of pulleys 218 are connected through the belt 219. When any set of pulleys 218 rotates, the belt 219 can be driven to drive the other set of pulleys 218 to rotate, thereby achieving the purpose of conveying.

[0033] The laser pipe welding machine also includes a laser welding machine 311, a laser welding head 312, a welding port 318 and an adjustment mechanism. The welding port 318 is opened inside the fuselage 1. The laser welding machine 311 is installed on the top of the fuselage 1 and is connected to the laser welding head 312. The laser welding machine 311 and the laser welding head 312 can be connected through a wire. The specific principle is: Laser emission: The laser welding machine 311 generates a laser beam through a laser. After the working material in the laser, such as Nd:YAG crystal, is excited by energy, it can emit a laser beam. Optical system: The laser welding machine 311 adjusts and controls the laser beam through the optical system. The optical system includes components such as a collimator, a reflector, and a lens, which can adjust the parameters such as the direction, focusing degree and shape of the laser beam. Welding process: The laser welding machine 311 focuses the laser beam on the welding part, so that the welding part is irradiated with a high-energy laser beam, thereby generating high temperature and high pressure conditions, so that the welding materials are melted and fused together. Control system: The laser welding machine 311 also needs to be equipped with a control system to control parameters such as welding temperature, depth and speed by adjusting parameters such as laser power, wavelength, pulse, etc., so as to obtain the desired welding effect. The laser welding head 312 is connected to the inner wall of the welding port 318 through an adjustment mechanism, and the laser welding head 312 is driven to move back and forth horizontally through the adjustment mechanism, so that multiple pipelines can be welded.

[0034] The adjusting mechanism includes a sliding block 313, a sliding groove 314, a threaded sleeve 315, a lead screw 316 and a second motor 317. The sliding groove 314 is formed in the inner wall of the top end of the welding joint 318. The sliding block 313 is slidably connected to the inside of the sliding groove 314 and a threaded sleeve 315 is fixed to the bottom end. The laser welding head 312 is installed at the bottom of the threaded sleeve 315.

The second motor 317 is installed on the outer side wall of the fuselage 1. The output end of the second motor 317 is connected to the lead screw 316. By turning on the second motor 317 to drive the rotation of the lead screw 316, under the action of the thread, the threaded sleeve 315 and the laser welding head 312 slide horizontally back and forth, achieving the purpose of automatically controlling the welding station of the laser welding head 312. The automatic use is more time-saving and labor-saving.

[0035] Working principle: When feeding is required, by pulling up the push plate 224 to make it slide along the inner wall of the slot 225, the push plate 224 drives the movable rod 222, the connecting frame 216 and the two groups of second conveying rollers 214 to move upward, and drives the spring 223 to be compressed. Subsequently, the staff inserts the pipe into the groove 215 in the first conveying roller 213. After releasing the push plate 224, under the elasticity of the spring 223, the two groups of second conveying rollers 214 are driven to press down. The groove 215 in the second conveying roller 214 fits the top of the pipe, achieving a pressing effect. Subsequently, turn on the first motor 217 to drive any one of the first conveying rollers 213 to rotate, and make the pulley 218 and the belt 219 rotate, driving the other first conveying roller 213 to rotate, achieving the effect of synchronous feeding.

[0036] When welding at different positions needs to be adjusted, by turning on the second motor 317 to drive the rotation of the sliding groove 314, under the action of the thread, the threaded sleeve 315 and the laser welding head 312 are driven to move horizontally, so that the laser welding head 312 corresponds to different positions of the pipe. By turning on the laser welding machine 311 to make the laser welding head 312 work, the welding requirements are met.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention.
