Description

Technical Field

[0001] This invention relates to the field of industrial pump processing technology, and in particular to an automatic laser welding equipment for industrial pump bodies. Background Technology

[0002] As a core piece of equipment in the field of fluid transportation, the sealing performance and structural strength of industrial pumps directly determine the operational stability and service life of the equipment, and the welding process is a key link in ensuring the quality of pump body forming.

[0003] Currently, industrial pump body welding is mostly carried out manually or semi-automatically. Manual welding not only requires a high level of skill from the operators, but is also susceptible to human error and fatigue during the welding process, resulting in low welding precision, uneven welds, and defects such as incomplete welds and weak welds. This affects the sealing performance and structural strength of the pump body. Furthermore, manual welding is inefficient and cannot meet the needs of large-scale pump body production. Secondly, existing semi-automatic welding equipment often lacks sufficient adjustment flexibility, making it difficult to achieve multi-dimensional angle adjustments and precise alignment during pump body welding. For complex industrial pump bodies, it cannot fully cover all welding areas, requiring multiple adjustments to the pump body or welding head position, which is cumbersome and time-consuming, further reducing welding efficiency and production capacity.

[0029] The welding adjustment assembly 6 is used to achieve multi-angle adjustment of the laser welding head 7, ensuring that the welding head can be accurately aligned with the welding part of the pump body. Specifically, it includes: a second adjustment shaft 61, a third transmission unit 62, an adjustment arm 63, an adjustment sleeve 64, and a fourth transmission unit 65.

The gear meshing transmission drives the adjusting sleeve 64 to rotate, thereby adjusting the welding angle of the laser welding head 7.

[0032] Please continue reading. Figures 1-5 The specific usage process of this embodiment is as follows: First, control the opening of the pump body clamp 8, place the pump body to be welded into the pump body clamp 8, and after the pump body clamp 8 completes the clamping and fixing, start the equipment to start the welding operation; by controlling the opening of the electric telescopic rod 12, when the electric telescopic rod 12 extends and retracts, it drives the support plate 13 to move up and down linearly along the cooperation direction of the limiting slide rod 14 and the limiting slide sleeve 15. At the same time as the support plate 13 moves, it drives the material platform 3 to move up and down synchronously, thereby driving the clamped and fixed pump body to complete the vertical linear lifting and lowering, realizing the adjustment of the pump body welding height.

[0033] By controlling the activation of the Y-axis motor 221, the Y-axis motor 221 drives the Y-axis lead screw 222 to rotate. The Y-axis lead screw 222 generates a horizontal driving force through its threaded engagement with the lead screw nut at the bottom of the Y-axis slide plate 225, causing the Y-axis slide plate 225 to move horizontally in a linear fashion along the Y-axis direction along the Y-axis slide rail 223, thereby synchronously driving the welding arm 4 to move in a linear fashion along the Y-axis direction. At the same time, the X-axis motor 231 is activated, driving the X-axis lead screw 232 to rotate. The X-axis lead screw 232, through its threaded engagement with the lead screw nut at the bottom of the welding arm 4, drives the welding arm 4 to move horizontally in a linear fashion along the X-axis slide rail 233. Through the coordinated adjustment of the X-axis and Y-axis, the laser welding head 7 can be adjusted to any position on the horizontal plane. Combined with the lifting action of the pump body, precise alignment of the welding position is achieved.

[0034] By controlling the activation of the first drive motor 521, the first drive motor 521 drives the first drive gear 522 to rotate. The first drive gear 522 meshes and drives the half-tooth disk 523 to rotate. The half-tooth disk 523 drives the first adjusting shaft 51 to rotate synchronously. When the first adjusting shaft 51 rotates, it drives the material seat 53 to swing up and down, which in turn drives the clamped pump body to swing up and down synchronously, adjusting the tilt welding angle of the pump body. At the same time, the second drive motor 541 is activated. After the second drive motor 541 is activated, it drives the second drive gear 542 to rotate. The second drive gear 542 meshes and drives the gear ring 543 to rotate. The gear ring 543 drives the adjusting disk 55 to rotate synchronously, which in turn drives the clamped pump body to rotate, realizing the adjustment of the welding angle in the circumferential direction of the pump body, ensuring that all welding parts of the pump body can be accurately connected to the laser welding head.

[0035] By controlling the activation of the third drive motor 621, the third drive motor 621 drives the first synchronous pulley 622 to rotate. The first synchronous pulley 622 drives the second synchronous pulley 623 to rotate via a synchronous belt. The second synchronous pulley 623 drives the second adjusting shaft 61 to rotate synchronously. When the second adjusting shaft 61 rotates, it drives the adjusting arm 63 to swing up and down, thereby synchronously driving the laser welding head 7 to swing and adjust to the tilt welding angle of the pump body. At the same time, the fourth drive motor 651 is activated. After the fourth drive motor 651 is activated, it drives the third gear 652 to rotate. The third gear 652 meshes with and drives the fourth gear 653 to rotate. The fourth gear 653 drives the adjusting sleeve 64 to rotate synchronously, thereby driving the laser welding head 7 to rotate. This adjusts the welding orientation of the laser welding head, realizing multi-angle and all-round laser welding operations, effectively improving welding efficiency and welding quality.

[0036] Example 1 The core difference between this embodiment and the above-described embodiments lies in the optimized transmission structure, which improves adjustment accuracy and operational stability, and adapts to the welding requirements of high-precision industrial pump bodies (such as high-pressure chemical pump bodies). The specific structure is as follows: In the material support assembly 1, the electric telescopic rod 12 is replaced by a servo electric push rod. The servo electric push rod is fixedly installed on the upper surface of the material base 11 by bolts. Its telescopic end is fastened to the pallet 13 by screws. Compared with the original electric telescopic rod, the servo electric push rod can achieve millimeter-level telescopic precision adjustment. With the sliding limit of the limit slide rod 14 and the limit slide sleeve 15, the lifting stability of the pallet 13 and the material platform 3 is further improved, avoiding the impact of lifting deviation on welding accuracy. At the same time, a buffer pad is added between the pallet 13 and the material platform 3. The buffer pad is made of high-temperature resistant silicone material and is fixed by screws. It can effectively absorb the vibration generated during equipment operation and reduce the impact of vibration on the pump body clamping stability and welding quality.

[0037] In the Y-axis adjustment unit 22 and X-axis adjustment unit 23 of the welding support assembly 2, the Y-axis lead screw 222 and X-axis lead screw 232 are both replaced with ball screws. The ball screw and lead screw nut use ball transmission, which can significantly reduce transmission friction and transmission clearance compared to the original ordinary lead screw, and improve the accuracy of horizontal movement of the welding arm 4. At the same time, high-temperature resistant grease is applied to the surface of the Y-axis slide rail 223 and X-axis slide rail 233. Regular lubrication can extend the service life of the slide rails and avoid movement deviation caused by slide rail wear. In addition, a reinforcing plate is added at the connection between the Y-axis slide plate 225 and the X-axis slider 234. The reinforcing plate is fastened to the Y-axis slide plate 225 and the X-axis slider 234 respectively by screws, which improves the installation stability of the welding arm 4 and prevents the welding arm from shaking during the welding process.

[0038] In the first transmission unit 52 of the material adjustment assembly 5, the half-tooth disk 523 is replaced with a full-tooth disk. The full-tooth disk is fixed to the side end of the first adjustment shaft 51 by a key connection and meshes with the first transmission gear 522. At the same time, the original limit block is removed and replaced by an angle encoder installed at the end of the first adjustment shaft 51. The angle encoder is fixed to the upper surface of the material platform 3 by screws and is connected to the first adjustment shaft 51 for transmission. It can detect the rotation angle of the first adjustment shaft 51 in real time and feed the signal back to the control system to realize precise closed-loop control of the pump body's up and down swing angle, which is suitable for the multi-angle welding requirements of complex welds in high-pressure chemical pump bodies. In the second transmission unit 54, a positioning pin is added between the gear ring 543 and the adjustment disk 55. The positioning pin is evenly distributed in the circumferential direction of the gear ring 543 and fixed by interference fit, which further improves the connection stability between the gear ring 543 and the adjustment disk 55 and avoids relative displacement during gear meshing transmission.

[0039] In the third transmission unit 62 of the welding adjustment assembly 6, the synchronous belt is replaced by a synchronous chain, and the first synchronous pulley 622 and the second synchronous pulley 623 are replaced by synchronous sprockets. The synchronous chain meshes with the synchronous sprocket for transmission. Compared with the synchronous belt transmission, the synchronous chain transmission has a stronger load-bearing capacity and higher transmission accuracy, which can avoid adjustment deviations caused by the aging and slippage of the synchronous belt. In the fourth transmission unit 65, a wear-resistant coating is added to the tooth surfaces of the third gear 652 and the fourth gear 653. The wear-resistant coating is made of titanium nitride, which can improve the wear resistance and service life of the gears, reduce the transmission gap caused by gear wear, and ensure that the rotation angle of the laser welding head 7 is precise and controllable.

[0040] The usage process of this embodiment is basically the same as that of the above-described implementation method. The difference lies in the synergistic effect of the servo electric push rod, ball screw, angle encoder and other structures, which can achieve higher precision position adjustment and angle control, meet the welding requirements of high-precision industrial pump bodies such as high-pressure chemical pumps, and further improve welding quality and pass rate.

[0041] Example 2 The core difference between this embodiment and the above-described embodiments lies in the optimized adaptation structure and the addition of auxiliary functions to meet the batch welding needs of miniaturized, multi-specification industrial pump bodies (such as small household water pumps and micro industrial pump bodies). The specific structure is as follows: In the material support assembly 1, the material base 11 adopts a movable structure. Four casters with brakes are installed on the lower end face of the material base 11. The casters are fixed by screws, which can facilitate the overall movement and fixation of the equipment and adapt to the layout requirements of different production stations. At the same time, the number of electric telescopic rods 12 is increased to two. The two electric telescopic rods 12 are symmetrically installed on both sides of the upper end face of the material base 11. Synchronous extension and retraction can further improve the lifting stability of the pallet 13 and avoid the instability of the small pump body due to the shift of the center of gravity.

[0042] In the welding support assembly 2, a protective railing is added to the upper surface of the welding base 21. The protective railing is fixedly installed on the edge of the welding base 21 with screws, and has a height of 80cm. This can effectively prevent laser radiation and sparks from causing injury to operators during the welding process, and improve the safety of equipment use. At the same time, a travel limit switch is added to the X-axis slider 234 of the X-axis adjustment unit 23. The travel limit switch is fixedly installed with screws and is set at both ends of the X-axis slide rail 233. When the X-axis slider 234 moves to the limit position, the travel limit switch is triggered, automatically cutting off the power to the X-axis motor 231 to avoid structural damage caused by excessive movement of the equipment. The Y-axis slide plate 225 of the Y-axis adjustment unit 22 adopts the same structure and is equipped with a travel limit switch to achieve bidirectional limit protection.

[0043] In the material adjustment assembly 5, the pump body clamp 8 is replaced with a quick-change modular clamp. The modular clamp includes a clamp base and a clamping head. The clamp base is fixedly installed on the side of the adjustment plate 55 with screws, and the clamping head is detachably connected to the clamp base with a snap-fit. The clamping head is available in various specifications to adapt to small industrial pump bodies of different sizes and structures. When changing, there is no need to disassemble the clamp base; only the clamping head needs to be replaced, which greatly improves the switching efficiency of multiple pump body specifications and meets the needs of mass production. At the same time, a clamping detection sensor is added to the side of the material seat 53. The clamping detection sensor is fixedly installed with screws and is set corresponding to the pump body clamp 8. It can detect the clamping status of the pump body in real time. When the clamping force is insufficient or the pump body is not clamped in place, the sensor sends a signal, and the equipment cannot start the welding operation, thus avoiding welding deviations and equipment failures caused by unstable clamping.

[0044] In the welding adjustment assembly 6, a laser positioner is added to the top of the adjustment arm 63. The laser positioner is fixedly installed on one side of the adjustment sleeve 64 with screws, and is consistent with the welding direction of the laser welding head 7. It can accurately position the welding part before welding, and facilitate the operator to quickly adjust the position of the pump body and the laser welding head, thereby improving the alignment efficiency. At the same time, a dustproof protective cover is added to the outside of the laser welding head 7. The dustproof protective cover is connected to the adjustment sleeve 64 by threads, which can prevent dust and spatter generated during the welding process from adhering to the lens of the laser welding head, affecting the welding accuracy and the service life of the equipment. The dustproof protective cover is removable, which is convenient for regular cleaning and maintenance.

[0045] In addition, this embodiment adds a control system, which includes a PLC controller and a touch operation panel. The PLC controller is fixedly installed on the side of the welding base 21 with screws, and the touch operation panel is embedded in the surface of the PLC controller. It can realize centralized control of various motors, sensors and laser welding heads of the equipment. Operators can set welding parameters, adjust movement speed and angle through the touch panel, and display the equipment operating status and fault information in real time, which is convenient for operation and maintenance. The control system also supports parameter storage function, which can store welding parameters of various pump body specifications. When switching pump body specifications later, it can be directly called up to further improve the efficiency of mass production.

[0046] Based on the above implementation method, this embodiment adds steps such as quick fixture replacement, laser positioning, and status detection, which can efficiently adapt to the batch welding needs of miniaturized and multi-specification industrial pump bodies, while improving the safety, operability, and maintenance convenience of the equipment, and expanding the scope of application of the equipment.

[0047] Example 3 The core difference between this embodiment and the above-described embodiments and the previous two embodiments lies in strengthening the structural load-bearing capacity and optimizing heat dissipation performance. It adapts to the welding requirements of large industrial pump bodies (such as large centrifugal pumps and axial flow pump bodies), and solves problems such as equipment deformation and reduced welding quality caused by the large weight of large pump bodies and concentrated welding heat. The specific structure is as follows: In the material support assembly 1, the material base 11 is integrally formed from thickened steel, with a thickness 30% greater than the original base. Reinforcing ribs are added to the bottom, and these ribs are welded to the material base 11 to form a stable support structure that can effectively bear the weight of the large pump body and prevent base deformation. The electric telescopic rod 12 is replaced with a high-load hydraulic telescopic rod. The hydraulic telescopic rod is bolted through and fixed to the center of the upper end face of the material base 11. Its telescopic end is fastened to the support plate 13 via a flange. Compared to servo electric push rods and ordinary electric telescopic rods, the high-load hydraulic telescopic rod has a stronger load-bearing capacity and better telescopic stability, enabling smooth lifting and lowering of heavy-duty pump bodies. Simultaneously, the limit slide rod 14 is replaced with a thickened stainless steel slide rod, and the limit sleeve 15 is replaced with a wear-resistant alloy sleeve. A clearance fit is used between the slide rod and the sleeve, and high-temperature grease is applied to improve sliding smoothness and enhance the load-bearing capacity of the limit structure, preventing damage to the limit structure during the lifting and lowering of the large pump body.

[0048] In welding support assembly 2, the welding base 21 adopts a concrete casting + steel reinforcement structure, and the bottom is fixed to the ground by expansion bolts, which further improves the overall support stability and avoids the overall shaking of the equipment during the welding of large pump bodies; in Y-axis adjustment unit 22 and X-axis adjustment unit 23, Y-axis slide rail 223 and X-axis slide rail 233 are replaced with heavy-duty linear slide rails, the slide rail cross-sectional size is increased, and the number of sliders is increased to 2 per set of slide rails, symmetrically distributed, which improves the load-bearing capacity of welding arm 4 and ensures that the welding arm moves smoothly without shaking when driving the laser welding head; at the same time, Y-axis motor 221 and X-axis motor 231 are replaced with high-power servo motors, which are used with gearboxes. The gearboxes are connected to the motor output end and the lead screw respectively through couplings, which can provide greater driving force to meet the heavy-load movement requirements of the welding arm driving the laser welding head and related components, while improving the adjustment accuracy.

[0049] In the material adjustment assembly 5, the first adjustment shaft 51 is made of high-strength alloy shaft with a diameter 25% larger than the original adjustment shaft. The bearing seats at both ends are replaced with heavy-duty rolling bearing seats, which enhances the load-bearing capacity and rotational stability of the adjustment shaft, enabling the large pump body to swing smoothly. The material seat 53 is made of cast steel and is integrally formed. It is double-fixed to the first adjustment shaft 51 by key connection and locking nut, which improves the connection firmness and prevents the material seat from loosening due to the weight of the large pump body. The pump body clamp 8 is replaced with a large heavy-duty chuck clamp. The chuck clamp is fixed to the side of the adjustment plate 55 by high-strength bolts. The clamp is made of wear-resistant alloy steel and can flexibly adjust the clamping range according to the outer diameter of the large pump body. The clamping force is increased by 50% compared to the original clamp, ensuring that no displacement occurs during the welding of the large pump body. At the same time, a thrust bearing is added at the shaft connection between the adjustment plate 55 and the material seat 53, which can effectively withstand the axial pressure of the large pump body and extend the service life of the shaft.

[0050] In the welding adjustment assembly 6, the adjustment arm 63 is welded from thickened steel plate to enhance structural strength and load-bearing capacity, providing stable support for the laser welding head and related transmission components. A reinforcing sleeve is added to the connection between the second adjustment shaft 61 and the adjustment arm 63. This sleeve is fixed to the adjustment shaft and arm via an interference fit, improving connection stability. The laser welding head 7 is replaced with a high-power laser welding head, doubling the power of the original head, meeting the welding requirements of thick-walled welds in large pump bodies. A water-cooling device is added to the rear end of the laser welding head 7, fixed to the adjustment arm 63 via a bracket and connected to the laser welding head 7 via a water pipe. This allows for the real-time removal of the large amount of heat generated during welding, preventing damage to the laser welding head due to overheating and reducing the impact of welding heat on the pump body material, thus improving welding quality. In the fourth transmission unit 65, both the third gear 652 and the fourth gear 653 are replaced with high-strength helical gears. The helical gears have a larger tooth surface contact area, resulting in better transmission smoothness and stronger load-bearing capacity, preventing gear damage under heavy loads.

[0051] In addition, an anti-sway bracket is added to the top of the welding arm 4 in this embodiment. The anti-sway bracket is fixedly installed on one side of the adjusting arm 63 with screws and connected to the water cooling heat dissipation device of the laser welding head 7. This can further improve the stability of the laser welding head and avoid welding deviation caused by equipment vibration during the welding process. A positioning reference block is added to the upper surface of the material table 3. The positioning reference block is fixedly installed with screws and is set correspondingly to the pump body clamp 8. It can be accurately positioned before clamping large pump bodies, reducing clamping and alignment time and improving welding efficiency. At the same time, temperature sensors are added to each transmission part of the equipment. The temperature sensors are fixedly installed with screws and can detect the temperature of the transmission components in real time. When the temperature exceeds the set threshold, a heat dissipation reminder is automatically triggered to avoid equipment failure caused by high temperature.

[0052] The usage process of this embodiment is basically the same as that of the above-described implementation method. The difference lies in the design of strengthening the structural load-bearing capacity, optimizing heat dissipation, and improving clamping force. It can stably support and weld large industrial pump bodies, solving the pain points such as equipment shaking, concentrated welding heat, and unstable clamping during the welding of large pump bodies. It ensures the welding accuracy and structural strength of the weld seam of large pump bodies, adapts to the large-scale production needs of large industrial pumps, further expands the application scope of the equipment, and enhances the practicality and market competitiveness of the equipment.

[0053] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
