Description

Technical Field

[0001] The invention relates to the technical field of pressure tank body welding processing, in particular to a positioning processing device for a pressure container body. Background Art

[0002] As industrial production continues to increase the safety and sealing requirements of pressure tanks, how to achieve high-precision, automated positioning and welding of pressure vessel tanks on the production line has become a hot topic in the industry. Since pressure tanks usually have thick walls, diverse shapes, and complex forces, the welding process needs to fully consider the reserved space of the welding parts, the clamping stability, and the control of high-temperature deformation. Especially in large-scale production situations, if positioning and clamping cannot be performed reasonably, problems such as weld position offset or uneven welding pool will often occur, which will affect the safety of the tank and the product qualification rate.

[0003] At present, most common pressure tank welding technologies use only a single welding device to perform circumferential welding on the tank. Its advantages are simple structure and low layout cost, but in actual application, it is easy to have problems such as concentrated heat input and uneven cooling. Since the different positions of the weld are in different heating states, there will be a large temperature difference in the welding part, and the tank structure will often be deformed at the welding position, which will have an adverse effect on the welding quality.

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Please see attached Figure 1 - Attachment Fig.10 The embodiment of the present invention provides a positioning processing device for a pressure vessel body, comprising:

[0043] Please see attached Figure 3, the loading and conveying mechanism 2 is fixedly connected to the middle upper surface of the mounting base plate 1, and its function is to drive the pressure tank body to move forward and backward to perform loading and unloading operations. The loading and conveying mechanism 2 includes a supporting pad 201 and a loading slide rail 202. The supporting pad 201 is fixedly connected to the middle upper surface of the mounting base plate 1, and the supporting pad 201 is fixedly connected to the middle upper surface of the mounting base plate 1. The lower side of the loading slide rail 202 is fixedly connected to the upper side of the supporting pad 201. The internal rotation of the loading slide rail 202 is connected to the first driving screw 203, and the rear side of the loading slide rail 202 is fixedly connected to the first driving motor 204, and the power output end of the first driving motor 204 is fixedly connected to the rear end of the first driving screw 203. The outer surface of the first driving screw 203 is threadedly connected to a conveying slider 205.

[0044] Specifically, the support pad 201 is fixedly connected to the upper surface of the middle part of the installation base plate 1, providing support and installation position for the loading slide rail 202. The loading slide rail 202 is fixedly connected to the upper side of the support pad 201 at its lower side, providing a movable space for the conveying slider 205, and cooperates with the first driving screw 203 to realize the forward and backward conveying of the pressure tank body. The first driving screw 203 drives the conveying slider 205 to perform linear reciprocating motion on the loading slide rail 202 through thread transmission, thereby realizing the loading or unloading of the pressure tank body. The first driving motor 204 is used to drive the first driving screw 203 to rotate, so as to realize the precise movement of the conveying slider 205. The conveying slider 205 is threadedly connected to the outer surface of the first driving screw 203, and can slide forward and backward along the loading slide rail 202.

[0045] Please refer to the attached Figure 4 The tank body clamping mechanism 3 is divided into two parts, the upper part of which is arranged on the rear side of the feeding and conveying mechanism 2 and is fixedly connected to the upper surface of the mounting base plate 1, and provides an installation position for other mechanisms, and the lower part of which is fixedly connected to the upper side of the feeding and conveying mechanism 2 and moves with the moving parts of the feeding and conveying mechanism 2, and its function is to clamp and fix the pressure tank to be processed. The tank body clamping mechanism 3 includes a fixed bracket 301 and a hydraulic clamping push rod 302. The lower side of the fixed bracket 301 is fixedly connected to the upper surface of the mounting base plate 1, the upper end of the upper hydraulic clamping push rod 302 is fixedly connected to the lower surface of the middle part of the fixed bracket 301, and the lower end of the lower hydraulic clamping push rod 302 is fixedly connected to the upper side of the conveying slider 205, and the adjacent ends of the hydraulic clamping push rod 302 are fixedly connected to the tank body clamping base 303, and the adjacent sides of the tank body clamping base 303 are fixedly connected to the clamping pad 304.

[0046] Specifically, the fixed bracket 301 provides a stable installation position and support structure for the upper hydraulic clamping push rod 302 and other upper components. The hydraulic clamping push rod 302 realizes the extension and retraction of the push rod through the hydraulic system, thereby driving the tank body clamping base 303 to clamp or loosen the pressure tank body. The tank body clamping base 303 is used to receive the clamping pad 304 and is adapted to the outer surface of the pressure tank body. The pressure tank body is compressed or loosened by the driving force of the hydraulic clamping push rod 302. The clamping pad 304 is a component that is in direct contact with the pressure tank body. The material used to make it has certain wear resistance and anti-slip properties, which can ensure the clamping effect and prevent damage to the tank body.

[0047] Since the positioning processing of the pressure tank body by this device requires the upper and lower cooperation of the tank body clamping mechanism 3, the tank body clamping mechanism 3 is divided into two parts, the upper part is a fixed part, with the fixed bracket 301 as the main support point, and does not move with the conveying mechanism; the lower part is a movable part, and the lower end of the lower hydraulic clamping push rod 302 is connected to the first driving screw 203 through the conveying slider 205, and can move back and forth with the feeding conveying mechanism 2. After the processing personnel places the pressure tank body on the lower clamping base 303, the processing personnel issues a command through the control mechanism 10, starts the first drive motor 204 to drive the conveying slider 205 and the lower half of the tank body clamping mechanism 3 to move backward together, and cooperates with the detection mechanism 9 to send the pressure tank body to the set position for preliminary alignment. Then, when the loading position detection device 901 and related sensors in the detection mechanism 9 confirm that the tank body has reached the predetermined position, the automatic control device 1002 issues a command, and the hydraulic clamping push rod 302 starts to move. The hydraulic clamping push rods 302 on the upper and lower sides extend, driving the tank body clamping base 303 and the clamping pad 304 to close to the surface of the tank body, applying sufficient clamping force to achieve clamping and fixing of the pressure tank body. After completing the entire set of welding processing procedures, the above operation is performed in reverse, and the processed pressure tank body is sent back to the front loading area, and then the processing personnel complete the unloading step and repeat the loading step.

[0048] Please see attached Figure 5, the side clamping drive mechanism 4 is fixedly connected to the upper surface of the rear side of the mounting base plate 1, and its function is to drive the side clamping feeding mechanism 5 to move to perform side feeding operation, the side clamping drive mechanism 4 includes a bottom slide 401 and a bottom driving screw 402, the side clamping drive mechanism 4 includes a bottom slide 401 and a bottom driving screw 402, the lower side of the bottom slide 401 is fixedly connected to the upper surface of the mounting base plate 1, and the left and right ends of the bottom driving screw 402 are rotatably connected to the inner surfaces of the left and right sides of the bottom slide 401, and the bottom A middle limit support block 403 is fixedly connected to the middle part of the bottom slide groove 401, and the middle part of the middle limit support block 403 is rotatably connected to the middle outer surface of the bottom driving screw 402. The bottom driving screw 402 is respectively provided with left and right sections of threads, and the threads rotate in opposite directions. The left and right outer surfaces of the bottom driving screw 402 are both threadedly connected with bottom sliders 404. The right side of the bottom driving screw 402 is fixedly connected with a second driving motor 405, and the power output end of the second driving motor 405 is fixedly connected to the right end of the bottom driving screw 402.

[0049] Specifically, the bottom slide 401 provides an installation position for the bottom drive screw 402, the bottom slider 404 and other components, provides a linear sliding guide rail for the bottom slider 404, and limits the rotational freedom of the bottom slider 404 during the movement, so that it can only make linear movements in the left and right directions, ensuring that the side clamping and feeding mechanism 5 can operate smoothly in the horizontal direction. The bottom drive screw 402 is provided with left and right sections of threads and the threads rotate in opposite directions. When the second drive motor 405 drives the bottom drive screw 402 to rotate in a certain direction, the threads at the left and right ends of the screw will cause the bottom sliders 404 on the left and right sides to move toward the middle simultaneously in relative directions, thereby achieving the clamping of the left and right sides of the tank body. If the bottom drive screw 402 rotates in opposite directions, the left and right bottom sliders 404 will move outward at the same time to loosen the side clamping of the tank body. The middle limit support block 403 provides additional support in the middle section of the screw, effectively preventing the screw from bending or swinging, thereby ensuring the synchronization and reliability of the clamping movement.

[0050] Please see attached Figure 6 , the side clamping and feeding mechanism 5 is fixedly connected to the upper side of the side clamping driving mechanism 4, and its function is to clamp and feed the left and right sides of the pressure tank body under the drive of the side clamping driving mechanism 4. The side clamping and feeding mechanism 5 includes a support rod 501 and a side clamping device 502. The lower ends of the support rods 501 are fixedly connected to the upper side of the bottom slider 404, and the lower sides of the side clamping devices 502 are fixedly connected to the upper ends of the support rods 501. The adjacent sides of the side clamping devices 502 are fixedly connected with three-jaw chucks 503, and the adjacent sides of the three-jaw chucks 503 are slidably connected with multiple sets of calibration movable blocks 504.

[0051] Specifically, the side clamping and feeding mechanism 5 is connected to the bottom slider 404 through the support rod 501, and the bottom slider 404 is threadedly connected to the bottom driving screw 402. When the second driving motor 405 drives the bottom driving screw 402 to rotate forward or reverse, the bottom slider 404 will move inward and outward in the horizontal direction along the bottom slide 401. As a result, the support rod 501 and the side clamping device 502 move synchronously inward or outward to achieve side feeding or side release of the pressure tank body. A three-jaw chuck 503 is set in the side clamping device 502, and the side clamping device 502 can drive the three-jaw chuck 503 and the calibration movable block 504 to tighten or loosen according to control requirements.

[0052] When the processing personnel load the side welding parts of the pressure tank body, the control personnel operate the side clamping device 502 to drive the three-jaw chuck 503 to clamp and fix the side welding parts. At this time, the side welding parts of the pressure tank body are tightly clamped to ensure its stability during subsequent welding or testing. The calibration movable block 504 on the three-jaw chuck 503 can be slid and positioned within a certain range, and the side welding parts and the pressure tank body are accurately positioned by manually or automatically cooperating with multiple sets of side laser positioning devices 902. The specific adjustment method is to adjust the upper and lower telescopic lengths of the two sets of hydraulic clamping push rods 302 through the data of multiple sets of side laser positioning devices 902 to achieve the purpose of clamping and positioning the pressure tank body. Since the multiple sets of side laser positioning devices 902 are arranged on the calibration movable block 504 according to the circumference and have a certain calibration range, the multiple sets of side laser positioning devices 902 cooperate with each other to determine that the pressure tank body and the side welding parts are in the same center, which is convenient for subsequent precise welding processing.

[0053] Please refer to the attached Figure 7, an annular welding support mechanism 6, the annular welding support mechanism 6 is arranged on the outside of the side clamping feeding mechanism 5, and its function is to provide an installation position for the annular welding movable mechanism 7, and cooperate with the annular welding movable mechanism 7 to weld the pressure tank body, the annular welding support mechanism 6 includes an alignment threaded drive rod 601, a third drive motor 602, the left and right ends of the alignment threaded drive rod 601 are rotatably connected to the left and right sides of the fixed bracket 301, the third drive motor 602 is fixedly connected to the right side of the fixed bracket 301, and the power output end of the third drive motor 602 is fixedly connected to the right end of the alignment threaded drive rod 601 The threads on the aligned threaded driving rod 601 are divided into left and right sections and rotate in opposite directions. The outer surfaces of the left and right ends of the aligned threaded driving rod 601 are threadedly connected with driving sliders 603. The front side of the driving slider 603 is fixedly connected with an outer supporting slip ring 606. The upper side of the outer supporting slip ring 606 is fixedly connected with an upper sliding connecting block 605. The middle part of the upper sliding connecting block 605 is slidably connected with an upper supporting sliding rod 604. The left and right ends of the upper supporting sliding rod 604 are fixedly connected to the upper left and right sides of the fixed bracket 301. The rear side of the upper sliding connecting block 605 is provided with a rear transmission port 607.

[0054] Specifically, the alignment thread drive rod 601 realizes the synchronous centripetal or centrifugal movement of the drive slider 603 through the structure in which the left and right sections of the thread rotate in opposite directions, thereby driving the annular welding movable mechanism 7 to move to a suitable position for welding. The third drive motor 602 is used to provide power to drive the alignment thread drive rod 601 to rotate forward or reverse, thereby realizing the synchronous movement of the drive slider 603. Driven by the third drive motor 602, the drive slider 603 reciprocates along the thread of the alignment thread drive rod 601, and transmits the movement to the outer support slip ring 606, thereby driving the outer support slip ring 606 or fine-tuning the position. The outer support slip ring 606 is used to provide an installation position for the annular welding movable mechanism 7, so that the annular welding movable mechanism 7 can perform positioning annular seam welding operations around the processing position of the pressure tank body.

[0055] The upper sliding connection block 605 is fixedly connected to the upper side support sliding ring 606, and the middle part thereof is slidingly connected to the upper side support sliding rod 604, and cooperates with the upper side support sliding rod 604 to form the main support mechanism of the outer side support sliding ring 606 and the annular welding movable mechanism 7, providing guidance and support for the movement of the outer side support sliding ring 606, so that the annular welding movable mechanism 7 can maintain stability and accurate positioning when moving in the activity area. The rear transmission port 607 is located at the rear side of the upper sliding connection block 605, and provides an installation and meshing transmission channel for the power transmission between the annular welding movable mechanism 7 or the welding drive mechanism 8 and the inner sliding gear ring 701.

[0056] Please refer to the attached Figure 8, an annular welding movable mechanism 7, the annular welding movable mechanism 7 is rotatably connected to the inner side of the annular welding support mechanism 6, and its function is to align the welding position under the drive of the annular welding support mechanism 6, and to weld the pressure tank body under the drive of the welding drive mechanism 8, the annular welding movable mechanism 7 includes an inner sliding gear ring 701 and an inner connecting ring 702, the inner sliding gear ring 701 is arranged inside the outer support slip ring 606, the outer side of the inner connecting ring 702 is fixedly connected to the inner side of the inner sliding gear ring 701, the outer edge of the inner connecting ring 702 is slidably connected to the inner side of the outer support slip ring 606, the inner side of the inner connecting ring 702 is fixedly connected to multiple groups of welding push rods 703, and the relatively movable ends of the welding push rods 703 are fixedly connected with welding devices 704.

[0057] Specifically, the inner sliding gear ring 701 is located inside the outer supporting slip ring 606, that is, the inner ring space of the outer supporting slip ring 606, and is meshed with the transmission gear 806 in the welding drive mechanism 8 through its outer tooth structure, so that the inner sliding gear ring 701 can be circularly rotated or positioned around the pressure tank body, providing a reliable circular motion path for the welding process. The outer side of the inner connecting ring 702 is fixedly connected to the inner side of the inner sliding gear ring 701, and the outer edge is slidably connected to the inner side of the outer supporting slip ring 606. As a supporting carrier between the inner sliding gear ring 701 and the tank body, it can not only rotate circumferentially with the inner sliding gear ring 701, but also maintain a certain sliding or positioning relationship with the outer supporting slip ring 606.

[0058] Multiple groups of welding push rods 703 are evenly distributed and fixed on the inner side of the inner connecting ring 702. By telescoping, the welding device 704 is pushed toward or pulled away from the welding surface of the pressure tank, providing power for precise adjustment and welding control of the welding device 704. The welding device 704 is fixedly connected to the relatively movable end of the welding push rod 703. Different types of welding heads are configured as needed to perform circumferential seam welding on the designated position of the pressure tank body. By cooperating with the welding push rod 703, the distance between the welding gun and the tank body can be finely adjusted.

[0059] The inner sliding gear ring 701 and the inner connecting ring 702 together form an annular structure, which can enclose the welding position of the pressure tank body. The annular structure can adapt to the circumferential welding requirements of different positions and sizes of the tank body. The outer edge of the inner connecting ring 702 is slidingly connected to the inner side of the outer support slip ring 606 and can rotate freely in the circumferential direction. When the outer support slip ring 606 is driven by the annular welding support mechanism 6 to adjust its position, the inner sliding gear ring 701 and the inner connecting ring 702 are also positioned for the corresponding welding processing position.

[0060] Please see attached Fig. 9, welding drive mechanism 8, the welding drive mechanism 8 is arranged on the rear side of the annular welding support mechanism 6, and its function is to provide power for the operation of the annular welding movable mechanism 7, the welding drive mechanism 8 includes a transmission cypress shaft 801 and a fourth drive motor 802, the left and right ends of the transmission cypress shaft 801 are rotatably connected to the left and right sides of the fixed bracket 301, the fourth drive motor 802 is fixedly connected to the right side of the fixed bracket 301, the power output end of the fourth drive motor 802 is fixedly connected to the right end of the transmission cypress shaft 801, and the transmission cypress shaft The middle part of 801 is fixedly connected with a limited position fixing sleeve 803, and the left and right outer surfaces of the transmission spline shaft 801 are slidably connected with transmission spline sleeves 804, and the left and right ends of the transmission spline sleeves 804 are rotatably connected with connecting toggle plates 805, and the front ends of the connecting toggle plates 805 are fixedly connected to the rear side of the outer support slip ring 606, and the middle outer surfaces of the transmission spline sleeves 804 are fixedly connected with transmission gears 806, and the outer edges of the transmission gears 806 pass through the rear transmission opening 607 and mesh with the outer edges of the inner sliding gear ring 701.

[0061] Specifically, the left and right ends of the transmission yoke shaft 801 are rotatably connected to the left and right sides of the fixed bracket 301, respectively, and serve as the core transmission shaft of the welding drive mechanism 8, transmitting the rotational power of the fourth drive motor 802 to the transmission spline sleeve 804 and the transmission gear 806 thereon, thereby driving the annular welding movable mechanism 7 to rotate or adjust the angle. The fourth drive motor 802 is fixedly connected to the right side of the fixed bracket 301, and its power output end is fixedly connected to the right end of the transmission yoke shaft 801 to provide rotational power for the welding drive mechanism 8. By adjusting the forward and reverse rotation, speed and torque of the motor, the speed and direction control of the circumferential welding of the pressure tank body can be achieved. The limiting fixing sleeve 803 is fixedly connected to the middle part of the transmission yoke shaft 801, which limits the middle position of the transmission yoke shaft 801, so that the transmission spline sleeve 804 is limited in the axial sliding position.

[0062] The outer surfaces of the left and right sides of the transmission spline shaft 801 are slidably connected with transmission spline sleeves 804, which cooperate with the transmission spline shaft 801 through the spline structure to achieve synchronous rotation while allowing the transmission spline sleeve 804 to slide moderately in the axial direction or a small range of radial direction, so that the spatial position change of the annular welding movable mechanism 7 can be adapted to the welding process for continuous power transmission. The function of the connecting toggle plate 805 is to drive the transmission spline sleeve 804 to follow the outer support slip ring 606 for synchronous movement and position adjustment. The transmission gear 806 is fixedly connected to the middle outer surface of the transmission spline sleeve 804, and its outer edge passes through the rear transmission port 607 and meshes with the outer edge of the inner sliding gear ring 701. It serves as the core meshing component between the welding drive mechanism 8 and the annular welding movable mechanism 7. By matching the tooth shape of the inner sliding gear ring 701, the rotational power provided by the fourth drive motor 802 is transmitted to the inner sliding gear ring 701, thereby driving the inner connecting ring 702, the welding push rod 703 and the welding device 704 to perform circumferential or segmented rotation welding on the surface of the tank body.

[0063] When the control mechanism 10 completes the front pressure tank loading step, the control mechanism 10 controls the side clamping drive mechanism 4, the side clamping loading mechanism 5, the annular welding support mechanism 6, and the annular welding movable mechanism 7 to move synchronously and relatively close to each other. After the side clamping drive mechanism 4 and the side clamping loading mechanism 5 complete the side clamping loading, the side loading clamping alignment is performed through the side laser positioning device 902, and the control mechanism 10 continues to issue the next welding adjustment instruction.

[0064] The third driving motor 602 starts to work, aligns the threaded driving rod 601 for fine-tuning rotation, drives the slider 603 to move toward the middle or outward, drives the outer supporting slip ring 606 and the upper sliding connecting block 605 to make corresponding positioning adjustments, so that the annular welding movable mechanism 7 and the weld position of the tank body are better aligned. In this process, the weld positioning and alignment device 903 arranged on the inner connecting ring 702 is used to assist the welding device 704 in the annular welding movable mechanism 7 to align the weld.

[0065] Once the appropriate alignment position is determined, the third drive motor 602 can be temporarily stopped or kept locked at a low speed torque to maintain the current position of the alignment threaded drive rod 601, and the outer support slip ring 606 and the upper sliding connection block 605 form a stable support structure. In this way, the annular welding movable mechanism 7 can be ensured to be in an ideal spatial position during the subsequent welding process, and then the welding push rod 703 pushes the welding device 704 close to the weld to a suitable distance.

[0066] After completing the above steps, the fourth driving motor 802 starts to run, and directly drives the transmission yoke shaft 801 to rotate through its power output end. By adjusting the speed and direction of the motor, the welding speed, rotation angle and rotation direction can be accurately controlled. A spline structure is provided on the transmission yoke shaft 801, so that the transmission spline sleeve 804 and the yoke shaft 801 can continue to transmit while maintaining a certain sliding freedom in the horizontal direction. The connecting toggle plate 805 is used to drive the transmission spline sleeve 804 and the transmission gear 806 to move synchronously with the outer support slip ring 606. When the transmission yoke shaft 801 rotates, the transmission spline sleeve 804 rotates together, driving the transmission gear 806 to rotate, thereby driving the inner sliding gear ring 701 to perform circumferential motion.

[0067] During the welding process, if the weld positioning and alignment device 903 or other sensors in the detection mechanism 9 detect weld deviation, improper welding speed, etc., the automatic control device 1002 can adjust the welding position and welding speed by adjusting the third drive motor 602 and the fourth drive motor 802 to provide the necessary fault tolerance space for the device.

[0068] After welding is completed, the side clamping drive mechanism 4 and the side clamping feeding mechanism 5 release the clamping of the pressure tank body and open towards each other first, and then the annular welding support mechanism 6 and the annular welding movable mechanism 7 are also opened towards each other to make way for the unloading channel of the pressure tank body that has completed the welding process. Then the hydraulic clamping push rod 302 contracts, and the feeding and conveying mechanism 2 sends the processed pressure tank body back to the front loading area, and then the processing personnel complete the unloading step and repeat the loading step.

[0069] Please see attached Figure 4 , Attachment Figure 6 , Attachment Figure 8 , detection mechanism 9, the detection mechanism 9 is respectively arranged on the tank clamping mechanism 3, the side clamping and feeding mechanism 5, and the annular welding movable mechanism 7. Its function is to cooperate with other mechanisms of the device to detect and position the pressure tank before welding. The detection mechanism 9 includes a feeding position detection device 901, a side laser positioning device 902, and a weld positioning and alignment device 903. The feeding position detection device 901 is fixedly connected to the upper lower surface of the fixed bracket 301, and the setting position of the feeding position detection device 901 corresponds to the setting position of the upper hydraulic clamping push rod 302. The side laser positioning device 902 is fixedly connected to the left and right adjacent sides of the calibration movable block 504. The weld positioning and alignment device 903 is fixedly connected to the inner side of the inner connecting ring 702, and the setting position of the weld positioning and alignment device 903 is set on the same rotation axis of the welding device 704.

[0070] Specifically, the main function of the feeding position detection device 901 is to detect and determine the actual position of the tank body during the feeding and conveying process, and to help determine when to start or stop the feeding and conveying mechanism 2 and when to perform the action of the tank body clamping mechanism 3. The main function of the side laser positioning device 902 is to detect the relative position of the side of the tank body by means of laser scanning. The specific adjustment method is to adjust the upper and lower telescopic lengths of the two groups of hydraulic clamping push rods 302 through the data of multiple groups of side laser positioning devices 902 to achieve the purpose of clamping and positioning the pressure tank body. The main function of the weld positioning and alignment device 903 is to detect and track the weld position of the pressure tank body, and to assist the automatic control device 1002 in real-time alignment and correction of the welding point or welding ring seam during the rotation of the annular welding movable mechanism 7 to ensure the quality and accuracy of the weld.

[0071] Please see attached Fig.10 , control mechanism 10, the control mechanism 10 is fixedly connected to the front upper surface of the mounting base 1, and its function is to automatically control the device. The control mechanism 10 includes a console fixing seat 1001 and an automatic control device 1002. The console fixing seat 1001 is fixedly connected to the front upper surface of the mounting base 1, the lower side of the console fixing seat 1001 is fixedly connected to the front upper surface of the mounting base 1, the lower side of the automatic control device 1002 is fixedly connected to the right upper surface of the console fixing seat 1001, and the upper side of the automatic control device 1002 is provided with The operation panel 1003 and the communication device 1004 are fixedly connected to the upper right surface of the console fixing base 1001, and the automatic control device 1002 is electrically connected to the first drive motor 204, the hydraulic clamping push rod 302, the second drive motor 405, the three-jaw chuck 503, the third drive motor 602, the welding push rod 703, the welding device 704, the fourth drive motor 802, the loading position detection device 901, the side laser positioning device 902, the weld positioning and alignment device 903, the operation panel 1003, and the communication device 1004.

[0072] Specifically, the console fixing seat 1001 provides a stable installation support position for the automatic control device 1002, the operation panel 1003, and the communication device 1004, ensuring that the equipment operator can easily set up or monitor. As the main control component of the device, the automatic control device 1002 is electrically connected to other actuators and detection mechanisms of the device, and semi-automatically controls the device through data acquisition, personnel instructions and internal programs. The operator uses the operation panel 1003 to perform operations such as parameter setting, manual control, fault diagnosis or process adjustment, and can also view the system status, alarm information and operating data in real time. The communication device 1004 is used to realize data communication between the device and the external system, and can upload real-time data through a wired network, a wireless network or other communication methods.

[0073] The first drive motor 204, the second drive motor 405, the third drive motor 602, and the fourth drive motor 802 correspond to key actions such as feeding and conveying, side clamping, annular welding support, and welding drive, respectively. The automatic control device 1002 sends start / stop, speed, and direction commands to them through electrical connections, and obtains real-time feedback through sensors or detection devices, thereby achieving precise closed-loop control.

[0074] The hydraulic clamping push rod 302, the three-jaw chuck 503, the welding push rod 703, and the welding device 704 are respectively responsible for the clamping of the tank body, the side clamping, the welding head feeding, and the welding operation. The automatic control device 1002 controls their working status through electrical connection. The feeding position detection device 901, the side laser positioning device 902, and the weld positioning and alignment device 903 respectively detect the position of the tank body during the feeding process, the accuracy of the side clamping, and the alignment of the weld during the welding process, and transmit the detection signal to the automatic control device 1002. The automatic control device 1002 combines these sensor data to adjust each actuator in real time. Through the operation panel 1003, the operator can view the current motor speed, clamping state, welding current, positioning error and other key information during the program running, and can manually correct important parameters. The communication device 1004 uploads the key data inside the automatic control device 1002 to the host computer or remote server.

[0075] Working principle: First, the operator places the pressure tank to be processed on the lower clamping base 303 of the feeding conveying mechanism 2, and starts the first driving motor 204 through the control mechanism 10 to rotate the first driving screw 203, driving the conveying slide 205 and the lower part of the tank body clamping mechanism 3 to move backward along the feeding slide rail 202. The feeding position detection device 901 monitors the current position of the pressure tank in real time. When the tank reaches the predetermined feeding position, the hydraulic clamping push rod 302 extends, pressing the clamping pad 304 against the outer surface of the pressure tank to achieve clamping and fixing in the up and down directions.

[0076] After completing the preliminary positioning, the side clamping drive mechanism 4 and the side clamping feeding mechanism 5 start to work together. The second drive motor 405 drives the bottom drive screw 402 to rotate forward or reverse, so that the bottom slider 404 moves toward the middle or both sides through relative movement, thereby driving the support rod 501 and the side clamping device 502 to move inward or outward synchronously. At this time, the three-jaw chuck 503 and the multiple groups of calibration movable blocks 504 arranged thereon will make fine adjustments according to the data provided by the side laser positioning device 902, so that the welded parts and the sides of the pressure tank body are concentric or clamped. In this way, not only can the side parts be effectively fixed during welding, but also precise alignment can be achieved through the three-jaw chuck 503 and the calibration movable block 504, ensuring the welding requirements of the side welded parts and the tank body.

[0077] When the tank body is firmly clamped in the up-down and left-right directions, the third drive motor 602 is started, and the threaded drive rod 601 is aligned for fine-tuning and rotating, so that the drive slider 603 moves inward or outward along the thread direction, driving the outer support slip ring 606 and the upper sliding connection block 605 to make fine adjustments in the horizontal direction, preparing for the subsequent welding position calibration of the annular welding movable mechanism 7. Subsequently, the weld positioning and alignment device 903 detects and aligns the tank body surface and the welding annular seam position. Once the precise positioning is completed, the third drive motor 602 can be stopped or kept locked at a low speed to maintain the required welding space position.

[0078] On this basis, the welding drive mechanism 8 starts to work, and the fourth drive motor 802 drives the transmission yoke shaft 801 to rotate. While the transmission spline sleeve 804 rotates synchronously on the yoke shaft 801, it is allowed to slide axially within a small range, so as to adapt to the changes of the annular welding movable mechanism 7 during the position adjustment process. As the transmission gear 806 and the inner sliding gear ring 701 mesh and rotate, the inner connecting ring 702 moves in a circle around the pressure tank body, and the welding push rod 703 pushes or pulls the welding device 704 radially to a suitable working distance, completing various forms of welding operations such as annular seam or spot welding at the required welding position.

[0079] During the entire welding stage, the detection mechanism 9 continuously collects the positioning information of the tank body and the real-time status of the weld: if there is a slight deviation in position or inappropriate welding speed during the welding process, the automatic control device 1002 will correct the motion parameters of the third drive motor 602 or the fourth drive motor 802 based on the feedback signals of the side laser positioning device 902 and the weld positioning and alignment device 903 to ensure the accuracy and quality of the welding action.

[0080] After all the circumferential seam welding is completed, the hydraulic clamping push rod 302 and the three-jaw chuck 503 release the clamping of the tank body in turn, and the side clamping drive mechanism 4 drives the side clamping feeding mechanism 5 to separate outward to make way for the tank body. Then, the first driving screw 203 rotates in the opposite direction, and the conveying slide 205 and the lower half of the tank body clamping mechanism 3 move forward again, and the welded pressure tank body is sent back to the loading area. After the operator removes the welded pressure tank body, the next welding operation cycle can be started.

[0081] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
