Detailed implementation manners

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0038] Embodiment 1, referring to Figures 1-5 , a ship stern post welding device for ship processing, including a support base 1 and a frame 2 welded to the outer wall of the top of the support base 1;

[0039] In this embodiment, a placement plate 3 is connected to the frame 2 through a welding height adjustment mechanism. A first controller 4 is fixedly installed on the outer wall at the rear of the frame 2, which facilitates the control of the electrical components of the entire embodiment. A plasma arc welding machine 5 is fixedly installed on the outer wall at the front of the placement plate 3, and an inflation mechanism is provided on the top of the placement plate 3;

[0040] Specifically, the inflation mechanism includes a gas mixing component, an argon storage tank 6 and a helium storage tank 7 fixedly arranged on the top outer wall of the placement plate 3 in sequence, a three-way pipe 8, an argon gas release valve 9 and a helium gas release valve 10;

[0041] Furthermore, the gas mixing component includes a mixing box 11 fixedly connected to the top outer wall of the placement plate 3, a support rod 12 fixedly connected to the inner wall at the bottom of the mixing box 11, a shaft body 13 rotatably installed on the support rod 12, and two impellers 14 fixedly sleeved on both ends of the shaft body 13 in sequence. When mixed gas is introduced into the mixing box 11, under the push of the air flow, the two impellers 14 will automatically rotate to improve the mixing effect of the mixed gas, thereby helping to improve the protection effect of the subsequent mixed gas on the plasma arc welding machine 5;

[0042] Furthermore, two ends of the three-way pipe 8 are respectively communicated with the argon storage tank 6 and the helium storage tank 7, the other end of the three-way pipe 8 is communicated with the rear of the mixing box 11, the front of the mixing box 11 is communicated with the plasma arc welding machine 5 through an air delivery pipe, the argon gas release valve 9 is installed at the connection between the argon storage tank 6 and the three-way pipe 8, the helium gas release valve 10 is installed at the connection between the helium storage tank 7 and the three-way pipe 8, and both the argon gas release valve 9 and the helium gas release valve 10 are solenoid valves and are both electrically connected to the first controller 4;

[0043] Specifically, the welding height adjustment mechanism includes a guiding component, a ball screw 15 rotatably installed in the frame 2, a lifting seat 16, a lead screw nut 17 fixedly sleeved in the lifting seat 16 and threadedly connected to the ball screw 15, and a stepping motor 18 fixedly installed on the top outer wall of the frame 2;

[0044] Furthermore, the output shaft of the stepping motor 18 penetrates through the top of the frame 2 and is coaxially and fixedly connected to the top end of the ball screw 15 through a coupling. The guiding component includes two guiding vertical shafts 19 symmetrically welded in the frame 2. Two linear bearings 20 are fixedly embedded in the lifting seat 16, and the two linear bearings 20 are respectively movably connected to the two guiding vertical shafts 19;

[0045] When this embodiment is specifically used: First, the stepping motor 18 is driven to rotate the ball screw 15 forward and backward. Subsequently, under the guidance of the guiding component, the lead screw nut 17 threadedly connected to the ball screw 15 will drive the lifting seat 16 to perform a lifting motion, which facilitates the flexible adjustment of the welding height of the plasma arc welding machine 5;

[0046] Secondly, during the welding process, by separately opening the argon gas release valve 9, the argon gas in the argon gas storage tank 6 can be released into the plasma arc welding machine 5 for use. Also, by separately opening the helium gas release valve 10, the helium gas in the helium gas storage tank 7 can be released into the plasma arc welding machine 5 for use. Additionally, both the argon gas release valve 9 and the helium gas release valve 10 can be opened simultaneously to release the mixed gas of argon and helium into the plasma arc welding machine 5 for use. In this way, the shielding gas can be flexibly switched according to different welding conditions, improving the online switching efficiency of the shielding gas.

[0047] Example 2, referring to Figure 1 and Figures 6-9 , this example is optimized based on Example 1. By providing two workpiece support mechanisms on the support base 1, both of the two workpiece support mechanisms include a hydraulic push component and a distance-adjustable bearing component. A second controller 35 is fixedly installed on the outer wall of the top of the support base 1, which facilitates the control of the electrical components in the entire example;

[0048] Specifically, the hydraulic push component includes two hydraulic push rods 21 fixedly installed on the side wall of the support base 1 and the same sliding seat 22 fixedly connected to the telescopic ends of the two hydraulic push rods 21. The sliding seat 22 forms a sliding fit with the support base 1;

[0049] Specifically, the distance-adjustable bearing component includes an installation groove opened on the top of the sliding seat 22, a positive and negative thread lead screw 23 rotatably installed in the installation groove, two adjusting seats 24 sequentially screwed onto the two threaded ends of the positive and negative thread lead screw 23, a servo motor 25 fixedly installed on the side wall of the sliding seat 22, two slide rails 26 symmetrically fixed on the outer wall of the top of the sliding seat 22, and two workpiece welding auxiliary rotators sequentially arranged on the tops of the two adjusting seats 24;

[0050] Furthermore, the output shaft of the servo motor 25 is coaxially fixedly connected to one end of the positive and negative thread lead screw 23, and both of the two adjusting seats 24 are slidably connected between the two slide rails 26;

[0051] When the distance-adjustable bearing component performs the adjustment operation: the servo motor 25 drives the positive and negative thread lead screw 23 to rotate forward and backward. Subsequently, the two adjusting seats 24 threadedly connected to the positive and negative thread lead screw 23 will slide along the two slide rails 26. That is, the forward and backward rotation of the positive and negative thread lead screw 23 can make the two adjusting seats 24 approach or move away from each other, which facilitates the flexible adjustment of the support distance between the two workpiece welding auxiliary rotators on the two adjusting seats 24, and thus facilitates adapting to the usage requirements of different lengths of ship stern column parts;

[0052] More specifically, the workpiece welding auxiliary rotator includes a control component, a fixed box 27 fixedly connected to the outer wall of the top of the adjusting seat 24, two rotating shafts 28 sequentially rotatably installed in the fixed box 27, and two rollers 29 sequentially fixedly sleeved on the two rotating shafts 28;

[0053] Furthermore, the control component includes two worm wheels 30 sequentially fixedly sleeved on one ends of the two rotating shafts 28, a protective cover 31 fixedly connected to the side wall of the fixed box 27, a driving motor 32 fixedly connected to the front outer wall of the protective cover 31 through a motor support plate, a transmission shaft 33 rotatably installed in the protective cover 31, and two worm gears 34 sequentially fixedly sleeved on the transmission shaft 33;

[0054] Furthermore, the two worm gears 34 are respectively engaged with the two worm wheels 30 and are both located inside the protective cover 31. The spiral directions of the two worm gears 34 are opposite, and the output shaft of the driving motor 32 is coaxially and fixedly connected to one end of the transmission shaft 33 through a coupling;

[0055] When the workpiece welding auxiliary rotator is working: the driving motor 32 drives the two worm gears 34 on the transmission shaft 33 to rotate. Subsequently, the two worm wheels 30 engaged with the two worm gears 34 with opposite spiral directions will drive the two rollers 29 on the two rotating shafts 28 to rotate relatively. In this way, the automatic rotation of the ship stern post parts can be controlled, so that the plasma arc welder 5 can perform uniform welding treatment on the welding joints of the two ship stern post parts, improving the welding quality.

[0056] The usage process of the present invention is as follows: First, the two ship stern post parts to be welded are respectively placed on the workpiece welding auxiliary rotators on the left and right by means of hoisting. Subsequently, the two hydraulic push rods 21 on both sides work synchronously to push the two sliding seats 22 to move closer to the center, thereby facilitating the automatic docking operation of the two ship stern post parts and improving the docking efficiency between the two;

[0057] Secondly, by the synchronous operation of all the workpiece welding auxiliary rotators, the automatic rotation of the two ship stern post parts in the docking state on both sides can be controlled. Subsequently, the welding height of the plasma arc welder 5 is flexibly adjusted through the welding height adjustment mechanism. At this time, the plasma arc welder 5 is used to weld the two rotating ship stern post parts. In this way, the plasma arc welder 5 can perform uniform welding treatment on the welding joints of the two ship stern post parts, effectively improving the welding quality;

[0058] Finally, during the welding process, the argon gas in the argon gas storage tank 6 can be released into the plasma arc welder 5 by separately opening the argon gas release valve 9, and the helium gas in the helium gas storage tank 7 can be released into the plasma arc welder 5 by separately opening the helium gas release valve 10. Also, the argon gas release valve 9 and the helium gas release valve 10 can be opened simultaneously to release the mixed gas of argon and helium into the plasma arc welder 5 for use. In this way, the shielding gas can be flexibly switched according to different welding conditions, improving the online switching efficiency of the shielding gas.
