DETAILED DESCRIPTION

[0036] The embodiment of the present application provides an automatic welding device, which effectively solves the problem that during the welding process, manpower is needed to first position the welded parts, and then operate the spray gun to weld the welded parts. This requires continuous movement of materials, resulting in high-intensity labor for the workers. When the workers are tired, the welding processing speed will be reduced. The welded parts are processed by holding the welding gun. In traditional manual welding, the speed of holding the gun and moving the arc is different and unstable, which can easily cause uneven welds and affect the quality of welding. The stepper motor installed inside the base drives the end of the rotating table to rotate, and the rotating table rotates at the top of the base, driving the three-jaw chuck and the welded part body to rotate at a uniform speed. At the same time, the outer side of the welded part body contacts the correction roller, pushing multiple correction rollers to rotate at the side end of the arc plate, and the correction rollers rotate with the welded part body to monitor the rotation distance and rotation posture of the welded part body. Automated welding can not only improve production efficiency, but also effectively reduce labor intensity.

[0043] Working principle:

[0044] In the first step, the main components of the overall control system include three parts, namely the control terminal 1, the fixed frame 15 and the configuration rotating table 12, wherein the control terminal 1 is used to control the movement of the welding machine and the welding movement parameters as well as the automatic control of the welding gun movement and the start-up of the welding machine. The above components can realize automatic work according to the logic control by compiling the ladder diagram program and downloading it to the PLC. The PLC coordinates all components to complete the automatic welding process according to human will. A stepper motor is installed inside the base 11. The stepper motor is an open-loop control element that converts an electrical pulse signal into an angular displacement or a linear displacement. In the case of non-overload, the running speed and stop position of the motor depend on the frequency and number of pulses of the pulse signal, and are not affected by load changes.

[0045] When in use, move the welding part body 13, place the welding part body 13 on the top of the rotating table 12, align the bottom end of the welding part body 13 with the rotating table 12, and clamp the bottom end of the welding part body 13 through the three-jaw chuck 21. The three-jaw chuck 21 is composed of a chuck body, a movable clamping jaw and a clamping jaw driving mechanism, and has a thread that meshes with the flat thread on the back of the disc bevel gear. When the small bevel gear is rotated through the square hole with a wrench, the disc gear rotates, and the flat thread on the back simultaneously drives the three clamping jaws to approach or withdraw from the center to clamp workpieces of different diameters, and then drives the first hydraulic rod 19 to extend and retract inside the fixed frame 15, so that the first hydraulic rod 19 drives the second support seat 17 to slide on the inner side of the fixed frame 15, and at the same time, the second support seat 17 drives the first support seat 16 to move synchronously inside the fixed frame 15 The second support seat 17 moves so that the welding gun body 23 on one side of the first support seat 16 approaches the weld on the side of the welding part body 13. At the same time, the second support seat 17 drives the limit plate 31 to move during the movement, so that the limit plate 31 drives the arc plate 36 on one side to first contact the outer side of the welding part body 13, so that the welding gun body 23 and the weld on the surface of the welding part body 13 have a certain distance. The arc plate 36 drives the correction roller 37 to perform a positioning. At the same time, by rotating the pull rod 38, the pull rod 38 is rotated at the top of the slider 35, and the end of the pull rod 38 rotates around the slider 35, so that the pull rod 38 drives the second clamping plate 39 at the top to slide away from the inside of the first clamping plate 33, and the position of the slider 35 and the arc plate 36 can be finely adjusted. According to different workpieces, the distance between the welding gun body 23 and the weld can be adjusted.

[0046] In the second step, the end of the rotating table 12 is driven to rotate by the stepper motor installed inside the base 11. The rotating table 12 rotates at the top of the base 11, driving the three-jaw chuck 21 and the welding part body 13 to rotate at a uniform speed. At the same time, the outer side of the welding part body 13 contacts the correction roller 37, pushing multiple correction rollers 37 to rotate at the side end of the arc plate 36. The correction roller 37 rotates with the welding part body 13, and the rotation distance and rotation posture of the welding part body 13 are monitored. The transmission line 34 on one side is transmitted to the inside of the control end 1 for real-time control. The welding gun body 23 processes the weld on the surface of the welding part body 13. After the welding is completed, the first hydraulic rod 19 is driven to allow the first hydraulic rod 19 to drive the first support seat 16 and the second support seat 17 to reset, and the rotating table 12 is also stopped. The rotation is stopped, the welding part body 13 is unloaded, and then the U-shaped plug plate 28 is slid to allow the U-shaped plug plate 28 to slide on the top of the plug rod 29. At the same time, the plug rod 29 is retracted at the side end of the positioning plate 27, so that the top of the plug rod 29 leaves the side end of the fixing ring 26, and the fixation of the fixing ring 26 is released. The fixing ring 26 is driven by the motor inside the first support seat 16 to rotate at the side end of the first support seat 16, and the fixing ring 26 synchronously drives the welding gun body 23 to rotate to adjust the use angle of the welding gun body 23. At the same time, a second hydraulic rod 32 is fixedly installed on the top of the second support seat 17. Under the control of the control end 1, the second hydraulic rod 32 is retracted at the top of the second support seat 17 to adjust the position of the first support seat 16 at the top of the second support seat 17, and the height and angle of the welding gun body 23 are adjusted to increase the flexibility of use.

[0047] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
