Description

Technical Field

[0001] This invention relates to the field of water pump processing technology, specifically a welding device for the production and processing of high-pressure water pumps. Background Technology

[0002] The high-pressure water pump casing welding production and processing equipment is an automated or semi-automated welding equipment specifically used to manufacture high-pressure water pump casings. Its core function is to connect the various components of the pump casing (such as flanges, cylinders, inlets and outlets) into a sealed and pressure-resistant whole through welding processes.

[0003] Chinese patent CN120306896A, authorized and published on July 15, 2025, discloses a magnetic pump housing welding production and processing device, including a box body. A frame is fixedly connected to the top of the box body. A tensioning mechanism is installed inside the box body. A feeding mechanism is provided on the inner wall of the frame. A lifting power cabinet is installed inside the box body. A discharging mechanism is provided on the left side of the box body. During welding, the cylinder wall is tightened to provide radial restraint to resist shrinkage deformation, effectively reducing thermal deformation during welding and improving tool yield. The internal heating components are exposed by opening the heat insulation cover to preheat the workpiece, reducing the temperature difference between the welding zone and the base material, reducing thermal stress, slowing down the cooling rate, preventing cold cracks, and further reducing thermal deformation during welding. After welding, the hydraulic support rod resets, allowing the heat insulation cover to close again to prevent the heating components from injuring the operator. In the aforementioned application, the equipment lacks a fixing device between the top of the pump and the flange to be welded during welding, which can easily cause the flange to shift position during welding by the robotic arm, thus hindering the welding process. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a welding apparatus for the production and processing of high-pressure water pumps, solving the problems mentioned in the background section. To achieve the above objectives, this invention provides the following technical solution: a welding apparatus for the production and processing of high-pressure water pumps, comprising: The base has a worktable on top, a support rod on top of the worktable, a hoisting and unloading device on top of the support rod, and a fixed turntable inside the worktable. Fixed columns are fixedly connected to the top of the front and rear sides of the worktable. A sliding groove is formed on the inner surface of each fixed column, and a slider is movably connected inside the groove. An electric hydraulic cylinder is fixedly connected to the top of the slider. A rotating plate is hinged to the inner side of the slider via a rotating shaft. A pressing plate is fixedly connected to the bottom of the slider, and a hydraulic block is fixedly connected to the bottom of the slider. A push block is movably connected to the bottom of the hydraulic block, and a spring is fixedly connected between the push block and the hydraulic block. The top of the hydraulic block is movably connected to the rotating plate via a transmission component. With the rotating plate and pressing plate in place, after the water pump workpiece is fixed by the fixed turntable device, the pressing plate moves downward, tightening the top of the water pump workpiece against the bottom of the flange. This causes the rotating plate to rotate, supporting the inner side of the water pump workpiece and fixing the position of the flange against the water pump workpiece. This prevents the welding robot arm from misaligning the flange during welding, thus making the welding process smoother.

[0005] Preferably, the transmission component includes a first hose, a second hydraulic block, a second push block, and a rotating block. The top of the first hydraulic block is fixedly connected to one end of the first hose, and the other end of the first hose is fixedly connected to the rear side of the second hydraulic block. The rear side of the second hydraulic block is fixedly connected to the outer side of the slider through a fixing plate. The front side of the second hydraulic block is movably connected to the second push block, and the bottom of the second push block is fixedly connected to the rotating block. The inner side of the rotating block is fixedly connected to the left side of the rotating shaft.

[0006] Preferably, a feeding device is fixedly connected to the right side of the workbench, a water pump workpiece is movably connected inside the fixed turntable device, a welding robotic arm is movably connected to the top of the workbench, a cooling and anti-deformation component is movably connected to the outside of the fixed column, and an auxiliary buffer component is movably connected to the bottom of the extrusion plate.

[0007] Preferably, there are two fixed columns, each symmetrically distributed about the centerline of the worktable; two sliding grooves; two electric hydraulic cylinders; two sliders; two rotating plates; two pressing plates; two push blocks; two springs; two hydraulic blocks; two hoses; two hydraulic blocks; two push blocks; and two rotating blocks.

[0008] Preferably, the cooling and anti-deformation assembly includes a push block three, a spring two, a hydraulic block three, a hose two, an L-shaped fixing plate, a hydraulic block four, a rack, a gear, a fixing frame, a rotating shaft, a rotating plate two, a nozzle, an air inlet pipe, and an air inlet fan. A hydraulic block three is fixedly connected inside the slide groove. A push block three is movably connected to the top of the hydraulic block three. A spring two is fixedly connected between the push block three and the hydraulic block three. The bottom of the hydraulic block three is fixedly connected to one end of the hose two, and the other end of the hose two is fixedly connected to the rear side of the hydraulic block four. The rear side of the fourth hydraulic block is fixedly connected to the outer side of the fixed column via an L-shaped fixing plate. A rack is movably connected to the inner side of the fourth hydraulic block. A fixing frame is fixedly connected to the outer side of the fixed column. A rotating shaft is movably connected between the fixing frames. A gear is fixedly connected to the top of the rotating shaft, meshing with the rack. A second rotating plate is fixedly connected to the outer side of the rotating shaft. A nozzle is fixedly connected to the top of the second rotating plate. The bottom of the second rotating plate is fixedly connected to the top of the air intake fan via an air intake pipe. The inner side of the air intake fan is fixedly connected to the outer side of the fixed column. A cooling and anti-deformation component is provided so that when the equipment is welding, the second rotating plate rotates, activating the air intake fan, causing cold air to be sprayed from the nozzle between the flange and the top of the water pump workpiece. This prevents the outer weld from maintaining a high temperature after heating and welding, reducing weld deformation caused by high temperature. Simultaneously, it allows the molten metal at the weld to cool and solidify rapidly, thereby improving equipment efficiency.

[0009] Preferably, there are two push blocks (three), four springs (two springs), two hydraulic blocks (three), two hoses (two hoses), two L-shaped fixing plates, two hydraulic blocks (four), two racks, two gears, four fixing brackets, two fixing brackets, two rotating shafts, two rotating plates (two nozzles), and two air inlet pipes.

[0010] Preferably, the angle between the nozzle and the horizontal direction is forty-five degrees.

[0011] Preferably, the auxiliary buffer assembly includes a groove, a third spring, a horizontal buffer plate, a fourth spring, and an inclined buffer plate. The bottom surface of the extrusion plate has a groove, the bottom of which is fixedly connected to the third spring. The bottom of the third spring is fixedly connected to the horizontal buffer plate. The inner surface of the rotating plate is fixedly connected to the fourth spring, and the inner side of the fourth spring is fixedly connected to the inclined buffer plate. This auxiliary buffer assembly ensures that when the extrusion plate moves downwards, the horizontal buffer plate contacts the top of the flange first, preventing direct collision between the extrusion plate and the flange, thus protecting the flange. Simultaneously, as the rotating plate rotates, the inside of the pump workpiece does not directly collide with the rotating plate, allowing the inclined buffer plate to contact the inner wall of the pump workpiece, thereby protecting the inside of the pump workpiece and preventing deformation during welding.

[0012] Preferably, there are two grooves, four springs (three), with two springs forming a group, two horizontal buffer plates, four springs (four), with two springs forming a group, and two inclined buffer plates.

[0013] Preferably, the size of the horizontal buffer plate is the same as the size of the groove.

[0014] This invention provides a welding device for the production and processing of high-pressure water pumps. It has the following beneficial effects: This welding device for the production and processing of high-pressure water pumps involves starting an electric hydraulic cylinder during operation. This cylinder works in conjunction with a chute, slider, rotating plate one, extrusion plate, push block one, hydraulic block one, hose one, hydraulic block two, push block two, and rotating block to move the extrusion plate downwards and rotate plate one, thereby fixing the flange to the top of the water pump workpiece and making the welding process smoother.

[0015] This welding device for high-pressure water pump production and processing, when the slider moves downward, works in conjunction with push block three, hydraulic block three, hose two, hydraulic block four, rack, gear, rotating shaft, rotating plate two, and air intake fan to make rotating plate two rotate, causing the nozzle to blow cold air towards the weld, thereby rapidly solidifying the unsolidified metal in the weld, thus improving equipment processing efficiency and reducing thermal deformation.

[0016] The welding device for producing and processing high-pressure water pumps converts the kinetic energy of the collision between the extrusion plate and the flange into the elastic potential energy of spring three when the extrusion plate moves downward. When the rotating plate one rotates, the kinetic energy of the collision between the rotating plate one and the water pump workpiece is converted into the elastic potential energy of spring four 1104, thereby preventing the water pump workpiece from deforming.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Example 1, please refer to Figures 1-4 A welding device for the production and processing of high-pressure water pumps, comprising: The base 100 has a worktable 200 on top, a support rod 300 on top, a hoisting and unloading device 400 on top, a fixed turntable device 500 inside the worktable 200 to fix the outer side of the water pump workpiece 700, a feeding device 600 fixedly connected to the right side of the worktable 200 to automatically feed the water pump workpiece 700, a water pump workpiece 700 movably connected inside the fixed turntable device 500, a welding robot arm 800 movably connected to the top of the worktable 200 to enable automatic welding, a cooling and anti-deformation component 1000 movably connected to the outer side of the fixed column 901, and an auxiliary buffer component 1100 movably connected to the bottom of the extrusion plate 906. Fixed columns 901 are fixedly connected to the top of the front and rear sides of the worktable 200. A slide groove 902 is provided on the inner surface of the fixed column 901. The slide groove 902 allows the slider 904 to move along the direction of the slide groove 902. The slider 904 is movably connected inside the slide groove 902. An electric hydraulic cylinder 903 is fixedly connected to the top of the slider 904. A rotating plate 905 is hinged to the inner side of the slider 904 through a rotating shaft. A pressing plate 906 is fixedly connected to the bottom of the slider 904. A hydraulic block 909 is fixedly connected to the bottom of the hydraulic block 909. A push block 907 is movably connected to the bottom of the hydraulic block 909. A spring 908 is fixedly connected between the push block 907 and the hydraulic block 909. The spring 908 allows the push block 907 to automatically reset. The top of the hydraulic block 909 is movably connected to the rotating plate 905 through a transmission component. The transmission components include a first hose 910, a second hydraulic block 911, a second push block 912, and a rotating block 913. The top of the first hydraulic block 909 is fixedly connected to one end of the first hose 910, and the other end of the first hose 910 is fixedly connected to the rear side of the second hydraulic block 911. The first hose 910 is provided so that the first hydraulic block 909 and the second hydraulic block 911 communicate internally. The rear side of the second hydraulic block 911 is fixedly connected to the outer side of the slider 904 through a fixing plate. The front side of the second hydraulic block 911 is movably connected to the second push block 912, and the bottom of the second push block 912 is fixedly connected to the rotating block 913. The inner side of the rotating block 913 is fixedly connected to the left side of the rotating shaft. There are two fixed columns 901, each symmetrically distributed about the center line of the worktable 200; two slides 902; two electric hydraulic cylinders 903; two sliders 904; two rotating plates 905; two pressing plates 906; two push blocks 907; two springs 908; two hydraulic blocks 909; two hoses 910; two hydraulic blocks 911; two push blocks 912; and two rotating blocks 913. The rotating plate 905 and the pressing plate 906 are configured so that after the water pump workpiece 700 is fixed by the fixed turntable device 500, the pressing plate 906 moves downward to fasten the top of the water pump workpiece 700 to the bottom of the flange. The rotating plate 905 rotates, thereby supporting the inner side of the water pump workpiece 700 and fixing the position of the flange and the water pump workpiece 700. This prevents the welding robot arm 800 from knocking the flange off during the welding process, making the welding process smoother.

[0021] In use, when the equipment starts working, the water pump workpiece 700 is fixed on the fixed turntable device 500. At this time, the electric hydraulic cylinder 903 is activated, causing the slider 904 to move downward along the slide groove 902, so that the pressing plate 906 fixes and presses the flange to the top of the water pump workpiece 700, causing the push block 907 to move upward, increasing the internal pressure of the hydraulic block 909, which is then transmitted to the hydraulic block 911 through the hose 910, increasing the internal pressure of the hydraulic block 911, causing the push block 912 to push outward, and the rotating block 913 to rotate with the push block 912, causing the rotating shaft to rotate, and the rotating plate 905 to rotate outward, thereby supporting the upper inner wall of the water pump workpiece 700, thus fixing the position of the flange and the water pump workpiece 700, so that the welding robot arm 800 will not knock the flange off during the welding process, thus making the welding process smoother.

[0022] Example 2, please refer to Figures 1-6Based on Embodiment 1, the cooling anti-deformation component 1000 includes a push block 3 1001, a spring 2 1002, a hydraulic block 3 1003, a hose 2 1004, an L-shaped fixing plate 1005, a hydraulic block 4 1006, a rack 1007, a gear 1008, a fixing frame 1009, a rotating shaft 1010, a rotating plate 2 1011, a nozzle 1012, an air inlet pipe 1013, an air inlet fan 1014, and an internal fixed connection in the slide groove 902. There is a hydraulic block 3 1003. A push block 3 1001 is movably connected to the top of the hydraulic block 3 1003. A spring 2 1002 is fixedly connected between the push block 3 1001 and the hydraulic block 3 1003. The spring 2 1002 allows the push block 3 1001 to automatically reset. The bottom of the hydraulic block 3 1003 is fixedly connected to one end of a hose 2 1004. The other end of the hose 2 1004 is fixedly connected to the rear side of a hydraulic block 4 1006. The hose 2 1004 allows communication between the interior of the hydraulic block 3 1003 and the interior of the hydraulic block 4 1006. The rear side of the hydraulic block 4 1006 is fixedly connected to the outer side of a fixed column 901 via an L-shaped fixing plate 1005. A rack 1007 is movably connected to the inner side of the hydraulic block 4 1006. A fixing frame 1009 is fixedly connected to the outer side of the fixing column 901. A rotating shaft 1010 is movably connected between the fixing frames 1009. A gear 1 is fixedly connected to the top of the rotating shaft 1010. 008, Gear 1008 meshes with rack 1007, Rotating plate 2 1011 is fixedly connected to the outer side of rotating shaft 1010, Spray head 1012 is fixedly connected to the top of rotating plate 2 1011, Spray head 1012 has an angle of 45 degrees with the horizontal direction, the bottom of rotating plate 2 1011 is fixedly connected to the top of air intake fan 1014 through air intake pipe 1013, and the inner side of air intake fan 1014 is fixedly connected to the outer side of fixed column 901; There are two push blocks 3 1001, four springs 2 1002, with two springs 2 1002 forming a group, two hydraulic blocks 3 1003, two hoses 2 1004, two L-shaped fixing plates 1005, two hydraulic blocks 4 1006, two racks 1007, two gears 1008, four fixing brackets 1009, with two fixing brackets 1009 forming a group, two rotating shafts 1010, two rotating plates 2 1011, two nozzles 1012, and two air inlet pipes 1013. The cooling and anti-deformation component 1000 is set up so that when the equipment is welding, the rotating plate 1011 rotates and the air intake fan 1014 is started, so that cold air is sprayed from the nozzle 1012 onto the top of the flange and the water pump workpiece 700. This prevents the outer weld from maintaining a high temperature after heating and welding, thereby reducing the deformation of the weld caused by high temperature. At the same time, it allows the molten metal at the weld to cool and solidify quickly, thereby improving the working efficiency of the equipment.

[0023] In use, based on Embodiment 1, when the slider 904 on the front side moves downward, the push block 1001 moves downward, increasing the internal pressure of the hydraulic block 1003. This internal pressure is then transmitted to the hydraulic block 1006 via the hose 1004, increasing the internal pressure of the hydraulic block 1006. This causes the rack 1007 to push outward, rotating the gear 1008 and the shaft 1010. The rotating plate 1011 then rotates with the shaft 1010. At this time, the intake fan 1014 is activated, allowing cold air to be sprayed from the nozzle 1012 through the intake pipe 1013 towards the outer weld. This prevents the outer weld from maintaining a high temperature after heating and welding, reducing deformation caused by high temperature. Simultaneously, it allows the molten metal at the weld to cool and solidify rapidly, thereby improving the equipment's working efficiency.

[0024] Example 3, please refer to Figures 1-8 Based on Embodiment 1 and Embodiment 2, the auxiliary buffer assembly 1100 includes a groove 1101, a third spring 1102, a horizontal buffer plate 1103, a fourth spring 1104, and an inclined buffer plate 1105. The bottom surface of the compression plate 906 is provided with a groove 1101. The bottom of the groove 1101 is fixedly connected to the third spring 1102. The third spring 1102 is provided so that the horizontal buffer plate 1103 can automatically reset. The bottom of the third spring 1102 is fixedly connected to the horizontal buffer plate 1103. The size of the horizontal buffer plate 1103 is the same as the size of the groove 1101. The inner surface of the rotating plate 905 is fixedly connected to the fourth spring 1104. The fourth spring 1104 is provided so that the inclined buffer plate 1105 can automatically reset. The inner side of the fourth spring 1104 is fixedly connected to the inclined buffer plate 1105. There are two grooves 1101, four springs 1102, with two springs 1102 forming a group, two horizontal buffer plates 1103, four springs 1104, with two springs 1104 forming a group, and two inclined buffer plates 1105. An auxiliary buffer assembly 1100 is provided. When the extrusion plate 906 moves downward, the horizontal buffer plate 1103 contacts the top of the flange first, thereby preventing the extrusion plate 906 from directly colliding with the flange and protecting the flange. At the same time, the rotating plate 905 rotates, and the inside of the water pump workpiece 700 does not directly collide with the rotating plate 905, so that the inclined buffer plate 1105 contacts the inner wall of the water pump workpiece 700, thereby protecting the inside of the water pump workpiece 700 and preventing deformation of the water pump workpiece 700 during welding.

[0025] In use, based on Embodiment 1 and Embodiment 2, when the extrusion plate 906 moves downward, the horizontal buffer plate 1103 contacts the top of the flange first, thereby converting the kinetic energy of the collision of the extrusion plate 906 into the elastic potential energy of the spring 1102, thus buffering the contact between the extrusion plate 906 and the flange. At the same time, the rotating plate 905 rotates, causing the inclined buffer plate 1105 to contact the upper inner wall of the water pump workpiece 700, thereby converting the kinetic energy of the collision of the rotating plate 905 into the elastic potential energy of the spring 1104, thus buffering the contact between the rotating plate 905 and the water pump workpiece 700, thereby protecting the interior of the water pump workpiece 700 and preventing deformation of the water pump workpiece 700 during welding.

[0026] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
