Description

Technical Field

[0001] The present invention relates to the technical field of shell processing and welding, and particularly to a welding device for processing an automobile engine cooling water pump shell. Background Art

[0002] During the operation of an automobile engine, a large amount of heat is generated, and an effective cooling system is required to maintain an appropriate working temperature. The cooling water pump is one of the key components of the engine cooling system. Its main function is to circulate the coolant within the engine, transfer the heat from the engine components to the radiator for heat dissipation, thereby ensuring the normal operation of the engine and preventing the engine from being damaged due to overheating. The cooling water pump shell is generally composed of multiple components, such as a front shell, a rear shell, a flange, etc. Welding is the key process to connect these components into a whole. Through welding, a firm connection between the components can be achieved, ensuring the sealing performance and strength of the shell.

[0003] When the existing welding equipment welds and connects the flange and the pipeline, it is impossible to keep the flange and the pipeline concentric during welding, and it is also very difficult to ensure that the side of the flange is perpendicular to the axis of the pipeline. If the flange is tilted, there will inevitably be a gap when the two ends of the pipeline are butted, leaving a safety hazard. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: A welding device for processing an automobile engine cooling water pump shell, including a fixing component, and a platform fixedly installed at the bottom of the fixing component; A positioning component, the positioning component is fixedly connected to the top of the platform; A welding component, the welding component is fixedly installed on the top of the platform, and the welding component is located on the side of the fixing component; Among them, the fixing component includes a fixing frame, the bottom of the fixing frame is fixedly connected to the middle of the top of the platform, the top of the fixing frame is fixedly connected to a fixing plate, a motor is fixedly connected to the top of the platform, the output end of the motor penetrates through the fixing plate, place the welding part to be processed on the top of the circular plate, the DC motor is externally powered to work, the DC motor drives the screw to rotate when working, the screw drives the slider to slide inside the square hole, so that the fixing block on the top of the slider is in close contact with the inner wall of the bottom ring of the welding part, thereby fixing the bottom ring of the welding part, and then move the positioning component downward to fix it with the pipe on the top of the welding part, thereby positioning the welding place to prevent the ring and the pipeline from shifting and the axes not being aligned. The top of the fixing plate is rotatably connected to a circular plate, a square hole is opened on the top of the circular plate, a screw is rotatably connected inside the square hole, a slider is arranged on the outer side of the screw, and a DC motor is fixedly connected to the outer side of the circular plate.

[0005] Preferably, the output end of the DC motor is fixedly connected to the screw rod. There are multiple square holes, and the multiple square holes are evenly distributed on the circular plate. A chute is provided in the middle of the top of the circular plate. The screw rod passes through the square hole and extends into the inside of the chute. The inner wall of the square hole is slidably connected to the slider. A fixed block is fixedly connected to the top of the slider close to the chute. One end of the fixed block close to the chute is set as an inclined edge, and a convex block is fixedly connected to the end of the fixed block away from the inclined edge. When the motor works, it drives the screw rod to rotate. The screw rod drives the slider to slide, and the slider drives the fixed block to contact the inner wall of the ring at the bottom of the welded part. By setting the convex block, the friction between the ring and the fixed block is increased, unnecessary movement of the ring in the radial and circumferential directions is restricted, a stable position is ensured during the working process, and at the same time, it helps to distribute the load more evenly and reduce the pressure per unit area. A limiting member is slidably connected inside the chute.

[0006] Preferably, the limiting member includes a sliding cylinder. The sliding cylinder is located inside the chute, and the outer side of the sliding cylinder is slidably connected to the inner wall of the chute. An extension block is fixedly connected to the outer edge of the bottom of the sliding cylinder. After the ring is fixed, the positioning component moves downward. Contact and extrusion occur between the positioning component and the sliding cylinder, causing the sliding cylinder to slide downward inside the chute, so that the cylinder inside the through groove is in close contact with the screw rod. Using the friction between the cylinder and the screw rod, the rotation of the screw rod is avoided during the welding process, thereby preventing the ring from shifting. A plurality of through grooves are provided on the outer side of the sliding cylinder, and the plurality of through grooves are evenly distributed on the sliding cylinder. A cylinder is fixedly connected to the inner wall of the through groove away from the extension block.

[0007] Preferably, the welding assembly includes a cylinder body fixedly connected to the top of the platform. A rotating shaft is rotatably connected inside the cylinder body. A motor is fixedly connected to the top of the cylinder body. The output end of the motor penetrates the cylinder body and extends into the interior of the cylinder body. The output end of the motor is fixedly connected to the rotating shaft. Side grooves are formed on the outer side of the cylinder body. When the welding piece is fixed, the motor is externally powered to work. The motor drives the rotating shaft to rotate, the rotating shaft drives the round block to move up and down, and the round block drives the welding torch to move up and down, so that the welding torch is aligned with the welding position. At the same time, the fixing rods on both sides of the ring block are respectively in contact with the ring and the pipeline, which can accurately determine the position of the welding torch relative to the welding part, ensure the accuracy of the welding position, improve the welding quality, and reduce welding defects caused by position deviation, such as incomplete penetration and misalignment. There are two side grooves, and the two side grooves are symmetrically arranged with the rotating shaft as the center. The inner wall of the side groove is slidably connected with a round block. A notch is formed inside the round block, and the notch is slidably connected with the cylinder body. A welding torch is fixedly connected to the outer side of the round block. A ring block is slidably connected to the outer side of the welding torch. Fixing rods are fixedly connected to the outer side of the ring block. There are two fixing rods, and the two fixing rods are arranged on both sides of the fixing rod and are vertically arranged. A return spring is fixedly connected to the outer side of the ring block axially. By being slidably mounted on the outer side of the welding torch, it can slide along the axial direction of the welding torch. This sliding design allows the fixing rods to flexibly adjust their positions according to the specific positions and dimensions of the pipeline and the ring, better realizing the fitting with the welding part. At the same time, in the natural state, the return spring exerts an outward elastic force on the ring block, making the ring block tend to slide outward, so that the fixing rods always maintain the contact pressure with the pipeline and the ring. The end of the return spring away from the ring block is fixedly connected to the welding torch.

[0008] Preferably, the positioning assembly includes a vertical plate fixedly connected to the top of the platform. A threaded rod is rotatably connected inside the vertical plate. A driving motor is fixedly connected to the top of the vertical plate. The output end of the driving motor penetrates the vertical plate, and the output end of the driving motor is fixedly connected to the threaded rod. A guide rod is fixedly connected inside the vertical plate. A moving plate is slidably connected to the outer side of the guide rod. The inside of the moving plate is threadedly connected to the outer side of the threaded rod. A positioning member is arranged at the end of the moving plate away from the vertical plate. The positioning member and the fixing assembly are located in the same vertical plane.

[0009] Preferably, the positioning member includes a round rod. When the motor operates, it drives the round plate to rotate, and the round plate drives the round rod to rotate, thereby driving the ring and the pipeline to rotate. At this time, the welding torch welds the welding position. The round rod is rotatably connected to the moving plate, and the round rod penetrates through the moving plate. A positioning plate is rotatably connected to the outer side of the round rod. The positioning plate is located below the moving plate. Guide rods are fixedly connected to the top edge of the positioning plate. There are multiple guide rods, and the multiple guide rods are evenly distributed around the round rod. A compression spring is fixedly connected to the top of the positioning plate. One end of the compression spring away from the positioning plate is fixedly connected to the moving plate. A square block is fixedly connected to the outer side of the bottom of the round rod. The driving motor is externally powered to operate. The driving motor drives the threaded rod to rotate, and the threaded rod drives the moving plate to move downward on the outer side of the axial direction of the guide rod, so that the moving plate drives the positioning member to approach the pipeline, and the positioning rod contacts and presses against the pipeline. The positioning rod rotates around the fixed ring under force. Under the relative support between the positioning rod and the rotating rod, the buffer spring is stretched under force, so that the positioning rod drives the baffle to move towards the direction of the round rod, and the inner wall of the baffle is in close contact with the inner wall of the pipeline. At the same time, the square block at the bottom of the round rod is located inside the chute. When the positioning assembly and the fixing assembly slide in the middle, they respectively fix the ring and the pipeline, which can provide relatively accurate positioning, reduce the error during the alignment of the ring and the pipeline, make the gap at the welding position more uniform, and is beneficial to obtaining high-quality welds. There are multiple square blocks, and the multiple square blocks are evenly distributed on the round rod. A fixed ring is fixedly connected to the outer side of the round rod. A positioning rod is rotatably connected to the outer side of the fixed ring. One end of the positioning rod away from the fixed ring is rotatably connected to a rotating rod. A positioning ring is slidably connected to the outer side of the round rod. A buffer spring is fixedly connected to the outer side of the axial direction of the positioning ring. One end of the buffer spring away from the positioning ring is fixedly connected to the fixed ring. One end of the rotating rod away from the positioning rod is rotatably connected to the positioning ring. A baffle is fixedly connected to the outer side of the positioning rod close to the rotating rod. A pressing plate is fixedly connected to the top of the outer side of the baffle. As the moving plate moves downward, the bottom of the pressing plate contacts and presses against the top of the pipeline. At this time, the ring and the pipeline are limited in the vertical direction and the horizontal direction, ensuring that the pipeline is in close fit with the ring, eliminating the gap between the two. During welding, the close contact can ensure that the weld is uniform and continuous, improve the strength and sealing performance of the welded joint, avoid welding defects caused by the existence of gaps, thereby ensuring the normal operation of the pump body and preventing medium leakage. An elastic cord is fixedly connected to the outer side of the positioning rod, and both ends of the elastic cord are fixedly connected to the positioning rod and the rotating rod.

[0010] The present invention provides a welding device for processing an automotive engine cooling water pump housing. It has the following beneficial effects: 1. The welding equipment for processing the housing of the automotive engine cooling water pump limits the ring and the pipe in the vertical and horizontal directions, ensuring the tight fit between the pipe and the ring, eliminating the gap between them. During welding, the tight contact can ensure uniform and continuous weld seams, improve the strength and sealing performance of the welded joint, avoid welding defects caused by the existence of gaps, thus ensuring the normal operation of the pump body and preventing medium leakage.

[0011] 2. The welding equipment for processing the housing of the automotive engine cooling water pump increases the friction between the ring and the fixed block by setting bumps, restricting the unnecessary movement of the ring in the radial and circumferential directions, ensuring a stable position during operation, and at the same time helping to distribute the load more evenly and reducing the pressure per unit area.

[0012] 3.
