Description

Technical Field

[0001] This invention belongs to the technical field of water pump guide vane welding equipment, specifically referring to a water pump guide vane welding production equipment. Background Technology

[0002] As a core component of fluid machinery such as centrifugal pumps and mixed-flow pumps, the guide vane of a water pump functions to guide and regulate fluid flow, efficiently converting kinetic energy into pressure energy, directly affecting the overall efficiency, stability, and lifespan of the pump. Currently, water pump guide vanes are still welded using spot welding for positioning, followed by continuous welding for fixation. This traditional welding method leads to errors in the production of water pump guide vanes. Structural improvements should be made to the current guide vane welding equipment to enhance the fixation effect and reduce production and maintenance costs. Summary of the Invention

[0003] In response to the above situation, in order to improve the welding operation process and reduce equipment production and maintenance costs while ensuring the fixation of parts, this invention provides a water pump guide vane welding production equipment. It adopts an automatic pressing and fixing method to fix the vane to the support plate. The equipment can continuously supply materials to ensure the continuity of welding production. It changes the traditional manual positioning welding method, improves production efficiency, avoids the use of sensor equipment, and reduces the manufacturing cost and subsequent maintenance cost of welding equipment.

[0004] The technical solution adopted by the present invention is as follows: The present invention provides a water pump guide vane welding production equipment, including an equipment box, a blade feeding device, a telescopic gripping welding device, a lifting automatic limiting structure, fixed blades and guide vane support plates. The blade feeding device is snapped into the equipment box, the telescopic gripping welding device is snapped into and rotatably installed in the equipment box, the lifting automatic limiting structure is snapped into the equipment box, the guide vane support plates are pressed on the lifting automatic limiting structure, and the fixed blades are placed on the blade feeding device, and the fixed blades are in contact with and connected to the telescopic gripping welding device.

[0005] Furthermore, the telescopic gripping welding device includes a pressing automatic gripping device and a wall-adhering welding device. The pressing automatic gripping device is snapped into the equipment housing, and the wall-adhering welding device is snapped into and slidably mounted on the pressing automatic gripping device. The pressing automatic gripping device includes a rotary motor, a rotary support, a pressing cylinder, an annular pressing plate, a side extension baffle, a pressing lifting support, a deflection support, a clamping plate, a support limiting side plate, and a support limiting protrusion. The rotary motor is fixedly mounted in the equipment housing, the rotary support is fixedly mounted on the rotary motor, the pressing cylinder is fixedly mounted on the rotary support, the annular pressing plate is fixedly connected to the pressing cylinder, and the side extension baffle is fixedly mounted on the annular pressing plate. On the side wall of the shaped pressing plate, the pressing and raising bracket is slidably engaged on the side extension baffle, and the pressing and raising bracket and the side extension baffle are connected by a spring. The bracket limiting side plate is fixedly engaged on the side extension baffle, and the bracket limiting protrusion is engaged and slidably engaged on the bracket limiting side plate. The deflection bracket is engaged and rotatably mounted on the bracket limiting side plate, and the clamping plate is engaged and rotatably mounted on the side extension baffle. The bottom wall of the pressing and raising bracket collides with the top wall of the fixed blade, so that the pressing and raising bracket rises and impacts the bottom wall of the deflection bracket. The deflection bracket rotates and squeezes the clamping plate, so that the clamping plate clamps the fixed blade. The fixed blade is fixed relative to the annular pressing plate under the synergistic action of the clamping plate and the annular pressing plate.

[0006] Furthermore, a spring connection is provided between the bracket limiting side plate and the bracket limiting protrusion, and an electromagnet is provided on both the bracket limiting side plate and the bracket limiting protrusion. The electromagnet is used to adjust the position of the bracket limiting protrusion on the bracket limiting side plate.

[0007] Furthermore, the wall-mounted welding device includes a welding torch slide, an annular rack, a movable gear, a gear limiting plate, a motor assembly, a motor limiting slide, and a welding torch. The welding torch slide is fixedly mounted on an annular pressing plate, and the annular rack is fixedly mounted inside the welding torch slide. The movable gear meshes with the annular rack, and the gear limiting plate slides along the annular rack. The movable gear is rotatably mounted inside the gear limiting plate. The motor assembly is connected to the movable gear, and the motor limiting slide is fixedly connected to the welding torch slide. The motor assembly slides along the motor limiting slide, and the welding torch is rotatably mounted on the gear limiting plate. The welding torch can adjust its rotation angle via a motor for welding and fixing blades and guide vane support plates.

[0008] Furthermore, the automatic lifting and limiting structure includes a limiting base plate, a lifting sliding plate, a limiting rack, an adjusting gear, a bevel gear assembly, a side wall pressing plate, and a feedback deflection clamp. The limiting base plate is fixedly installed on the equipment housing. The lifting sliding plate engages and slides relative to the limiting base plate in the vertical direction. The lifting sliding plate and the limiting base plate are connected by a spring. The limiting rack is fixedly installed on the bottom wall of the lifting sliding plate. The adjusting gear meshes with the limiting rack. The bevel gear assembly and the adjusting gear are fixedly connected by a bracket. The side wall pressing plate and the bevel gear assembly are fixedly connected by a bracket. The feedback deflection clamp is rotatably installed on the upper wall of the limiting base plate by engaging with the bracket. The side wall pressing plate and the feedback deflection clamp are in contact. When the side wall pressing plate deflects, one end of the feedback deflection clamp is squeezed by the side wall pressing plate and rotates simultaneously. The side wall at the end of the fixed blade is fixed by the side wall pressing plate and the feedback deflection clamp.

[0009] Furthermore, a housing is provided on the bottom wall of the limiting base plate, and the adjusting gear and bevel gear assembly are both engaged and installed inside the housing.

[0010] Furthermore, the limiting base plate is provided with a rack groove, and the limiting rack passes through the limiting base plate and meshes with the adjusting gear below the limiting base plate.

[0011] Furthermore, the blade feeding device includes a feeding platform, an end push plate, a diverting boss, and a lifting cylinder. The feeding platform is installed inside the equipment housing. The end push plate is engaged and slidably installed on the feeding platform. The diverting boss is engaged and slidably installed on the feeding platform. The lifting cylinder is fixedly installed on the equipment housing. The diverting boss is connected to the lifting cylinder.

[0012] Furthermore, the end push plate is connected to the feeding table by a spring. The end push plate pushes the fixed blade on the diversion boss to move forward, which facilitates the automatic gripping device to automatically grab the fixed blade.

[0013] Furthermore, the upper wall of the diversion boss is provided with a protrusion of a triangular prism structure, which separates the fixed blades when the diversion boss moves up.

[0014] Preferably, the protrusions of the triangular prism structure are arc-shaped to better push and fix the blades.

[0015] The water pump guide vane welding production equipment provided in this solution has the following advantages:

[0016] (1) After the pressing and lifting bracket and the fixed blade are pressed and contacted, the pressing and lifting bracket is raised and presses one end of the deflection bracket, further changing the rotation angle of the deflection bracket. After the deflection bracket rotates, it squeezes the clamping plate, thereby pressing and fixing the side wall of one end of the fixed blade. When the annular pressing plate presses and lifts the sliding plate, the mutual meshing relationship of the gear and rack is used to realize the deflection effect of the side wall pressing plate. With the help of the feedback deflection clamping plate, the side wall of the other end of the fixed blade is pressed and fixed, so as to ensure the accuracy of the positioning when welding the fixed blade later, and avoid using the time-consuming and inaccurate operation method of spot welding positioning again.

[0017] (2) The triangular protrusions on the surface of the diversion boss effectively separate the array of fixed blades, avoiding the accumulation of fixed blades and affecting the ring pressing plate to clamp the fixed blades. Attached Figure Description

[0034] like Figures 1-12As shown, the present invention provides a pump guide vane welding production equipment, including an equipment housing 1, a blade feeding device 2, a telescopic gripping welding device 3, a lifting automatic limiting structure 4, a fixed blade 5, and a guide vane support plate 6.

Deflection bracket 15 is engaged and rotatably mounted on bracket limiting side plate 17. Clamping plate 16 is engaged and rotatably mounted on side extension baffle 13.

[0039] A spring connection is provided between the bracket limiting side plate 17 and the bracket limiting protrusion 18. Both the bracket limiting side plate 17 and the bracket limiting protrusion 18 are equipped with electromagnets, which are used to adjust the position of the bracket limiting protrusion 18 on the bracket limiting side plate 17.

[0040] The wall-mounted welding device 8 includes a welding torch slide 19, an annular rack 20, a moving gear 21, a gear limiting plate 22, a motor assembly 23, a motor limiting slide 24, and a welding torch 25. The welding torch slide 19 is fixedly mounted on the annular pressing plate 12, and the annular rack 20 is fixedly mounted inside the welding torch slide 19. The moving gear 21 meshes with the annular rack 20. The gear limiting plate 22 slides along the annular rack 20 and is rotatably mounted inside the gear limiting plate 22. The motor assembly 23 is connected to the moving gear 21, and the motor limiting slide 24 is fixedly connected to the welding torch slide 19. The motor assembly 23 slides along the motor limiting slide 24 and the welding torch 25 is rotatably mounted on the gear limiting plate 22.

[0041] The automatic lifting limit structure 4 includes a limit base plate 26, a lifting sliding plate 27, a limit rack 28, an adjusting gear 29, a bevel gear assembly 30, a side wall pressing plate 31, and a feedback deflection clamping plate 32. The limit base plate 26 is fixedly installed on the equipment housing 1. The lifting sliding plate 27 is engaged and slid relative to the limit base plate 26 in the vertical direction. The lifting sliding plate 27 and the limit base plate 26 are connected by a spring. The limit rack 28 is fixedly installed on the bottom wall of the lifting sliding plate 27. The adjusting gear 29 meshes with the limit rack 28. The bevel gear assembly 30 and the adjusting gear 29 are fixedly connected by a bracket. The side wall pressing plate 31 and the bevel gear assembly 30 are fixedly connected by a bracket. The feedback deflection clamping plate 32 is engaged and rotatably installed on the upper wall of the limit base plate 26 by a bracket. The side wall pressing plate 31 and the feedback deflection clamping plate 32 are in contact.

[0042] The bottom wall of the limiting base plate 26 is provided with a housing 33, and the adjusting gear 29 and the bevel gear assembly 30 are both engaged and installed in the housing 33.

[0043] The limiting base plate 26 is provided with a rack and pinion groove, and the limiting rack 28 passes through the limiting base plate 26 and meshes with the adjusting gear 29 below the limiting base plate 26.

[0044] In practical use, the fixed blade 5 is placed on the feeding table 34. Under the pushing action of the end push plate 35, the fixed blade 5 moves to one end of the feeding table 34. In order to avoid the fixed blade 5 from piling up and making it difficult for the clamping device to clamp the fixed blade 5 from the feeding table 34, it is necessary to control the extension of the lifting cylinder 37. When the diversion boss 36 rises, the triangular protrusion on its surface effectively separates the fixed blade 5 to both sides of the triangular protrusion, thereby changing the spacing between the fixed blades 5.

[0045] The rotating bracket 10 rotates under the action of the rotating motor 9. The pressing cylinder 11 moves to the center position of the four feeding platforms 34. The pressing cylinder 11 extends, and the annular pressing plate 12 presses down. The side wall of the annular pressing plate 12 contacts the fixed blade 5 on the feeding platform 34. The bottom wall of the pressing lifting bracket 14 contacts the top wall of the fixed blade 5. The pressing lifting bracket 14 rises, causing the deflection bracket 15 to rotate. When the deflection bracket 15 rotates, it presses one side of the clamping plate 16. The clamping plate 16 deflects. With the cooperation of the clamping plate 16 and the annular pressing plate 12, the fixed blade 5 is fixed between the annular pressing plate 12 and the clamping plate 16.

[0046] When the deflection bracket 15 rotates, the bracket limiting protrusion 18 is no longer supported by the side wall of the deflection bracket 15. The bracket limiting protrusion 18 pops out from the bracket limiting side plate 17. The bracket limiting protrusion 18 prevents the deflection bracket 15 from rotating in the opposite direction, ensuring that the deflection bracket 15 is always in the state of pressing the clamping plate 16.

[0047] When it is necessary to release the clamping plate 16, the electromagnets on the bracket limiting side plate 17 and the bracket limiting protrusion 18 are energized, the two sets of electromagnets are attracted, the bracket limiting protrusion 18 is hidden inside the bracket limiting side plate 17, the deflecting bracket 15 rotates under the action of the torsion spring, the clamping plate 16 loses the pressure of the deflecting bracket 15, and the fixed blade 5 is released from between the deflecting bracket 15 and the annular pressing plate 12.

[0048] After clamping and fixing the blade 5, the rotating bracket 10 rotates, causing the annular pressing plate 12 to move above the limiting base plate 26. The operator places the lifting sliding plate 27 on the limiting base plate 26, and then the annular pressing plate 12, carrying the fixing blade 5, presses against the guide vane support plate 6. After being pressed, the lifting sliding plate 27 slides downward, and the limiting rack 28 on the bottom wall of the lifting sliding plate 27 moves downward. The adjusting gear 29 rotates under meshing action, and the bevel gear assembly 30 transmits power to... On the side wall pressing plate 31, the side wall pressing plate 31 deflects and presses one side of the fixed blade 5. When the side wall pressing plate 31 rotates, the feedback deflection clamp 32 is pressed on one side. The feedback deflection clamp 32 rotates synchronously. The feedback deflection clamp 32 and the side wall pressing plate 31 work together to clamp and fix one end of the fixed blade 5. At this time, the two ends of the fixed blade 5 are fixed by the side wall pressing plate 31, the feedback deflection clamp 32, the clamping plate 16, and the annular pressing plate 12, respectively.

[0049] Then, the motor connected to the welding gun 25 is controlled to work. The welding gun 25 rotates and the gun head is aligned with the gap between the fixed blade 5 and the guide vane support plate 6. The welding gun 25 works, and at the same time, the moving gear 21 rotates. Under the locking action of the gear limiting plate 22 on the annular rack 20 and the limiting action of the motor limiting slide groove 24, the moving gear 21 rotates along the annular rack 20. Since the annular rack 20 is concentric with the side wall of the fixed blade 5, the welding gun 25 slides and welds along the side wall of the fixed blade 5, realizing the design effect of welding the fixed blade 5 to the guide vane support plate 6.

[0050] After welding is completed, the electromagnet is energized and attracted, the welded guide vane is separated from the equipment, and the guide vane is removed from the lifting sliding plate 27.
