Description

Technical Field

[0001] This invention relates to the field of turbocharger welding technology, specifically to an automatic welding equipment for turbocharger processing. Background Technology

[0002] As a core component of modern internal combustion engines, the performance of turbochargers directly affects the engine's power output and fuel economy. The core components of a turbocharger consist of a turbine shaft, compressor impeller, and turbine impeller. These components need to be precisely welded into an integral structure. In the manufacturing process of turbochargers, the welding quality between the turbine shaft and turbine impeller is particularly critical. Its connection strength, coaxiality, and dynamic balance performance directly determine the reliability and service life of the entire turbocharger.

[0003] Traditional welding equipment uses a split clamping device, requiring the turbine shaft and turbine impeller to be clamped and positioned separately. Due to the lack of an effective automatic centering mechanism, the coaxiality of the workpiece depends entirely on the operator's experience and skill level, resulting in poor product consistency. Under high-speed rotation conditions, even a small coaxiality deviation can cause serious dynamic balance problems, generating vibration and noise, and affecting the working performance of the turbocharger. Therefore, an automatic welding equipment for turbocharger processing is proposed to solve the above-mentioned problems. Summary of the Invention

[0009] Preferably, the driven clamping mechanism further includes: Two circular rings, number two, are respectively set on both sides of circular ring one, and circular rails, number three, are fixedly connected to both sides of circular ring one; A rotating ring four is fixedly connected to the left circular ring two and rotates on the circular track three located on one side; The second ring on the right side is rotatably connected to the first ring by two rotating rings, and the two rotating rings are fixedly connected by a connecting rod; Each of the two rings has two arc-shaped plates on its outer wall, and a push rod is fixedly connected to the inner wall of the arc-shaped plate and extends movably through the ring into its interior. An arc-shaped clamp is fixedly connected to the extension end of the push rod and is used to clamp the connecting shaft on the turbine. A bidirectional screw is rotatably connected to the mounting block on the outer wall of the ring, and threaded through the two arc-shaped plates respectively, for synchronously driving the arc-shaped plates to move.

[0010] Preferably, an arc-shaped extension clamp is fixedly connected to one side of the arc-shaped clamp near the turbine shaft, for clamping the end of the turbine shaft, and the arc-shaped extension clamp extends into the interior of the ring to push the ring down.

[0020] The active clamping mechanism 2 also includes: Mounting base 27 is fixedly connected above rotating ring 22, and a motor 28 is mounted on one side of mounting base 27. The output end of motor 28 moves through both mounting bases 27. A gear 29 is installed at the output end of the motor 28 and meshes with the gear ring 25 to drive the gear ring 25 to rotate.

[0022] The driven clamping mechanism 4 includes: The support base 44 is fixedly connected to the top of the welding table 1, and two sliding columns 45 are slidably connected on the support base 44. The support ring 43 is fixedly connected to the top of the two sliding columns 45, and the outer wall of the sliding column 45 is fitted with a spring 46 for pushing the support ring 43 upward. An annular ring 41 is positioned above the support ring 43, and two rails 42 are fixedly connected to the outer wall of the annular ring 41, allowing it to rotate within the support ring 43 via the rails 42.

[0023] The driven clamping mechanism 4 also includes: Two circular rings 47 are respectively set on both sides of circular ring 41, and circular rails 414 are fixedly connected to both sides of circular ring 41. A rotating ring 415 is fixedly connected to the left circular ring 2 47 and rotates on the annular rail 3 414 located on one side; The second ring 47 on the right side is rotatably connected to the first ring 41 by two rotating rings 412, and the two rotating rings 412 are fixedly connected by a connecting rod 413. Each of the two rings 47 has two arc-shaped plates 48 on its outer wall, and the inner wall of the arc-shaped plate 48 is fixedly connected to a push rod 49, which extends into the ring 47 through it. The arc-shaped clamp 410 is fixedly connected to the extension end of the push rod 49 and is used to clamp the connecting shaft on the turbine 6; A bidirectional screw 411 is rotatably connected to the mounting block on the outer wall of the second annulus 47, and is threaded through the two arc-shaped plates 48 respectively, for synchronously driving the arc-shaped plates 48 to move.

[0024] An arc-shaped extension clamp 416 is fixedly connected to one side of the arc-shaped clamp 410 near the turbine shaft 5, for clamping the end of the turbine shaft 5, and the arc-shaped extension clamp 416 extends into the inside of the ring 41 for pushing the ring 41 downward.

[0025] Positioning mechanism 3 includes: A sliding hole is provided on one side of the top of welding station 1; The adjusting screw 32 is rotatably connected to the inner wall of the sliding hole and moves outward through it. The positioning seat 31 slides within the sliding hole and is threadedly connected to the outer wall of the adjusting screw 32, and is used to abut against the turbine 6 for positioning.

[0026] Positioning mechanism 3 also includes: The positioning rod 33 is movably connected to the positioning seat 31, and one side is in contact with the shaft center of the turbine 6; A tension spring 34 is sleeved on the outer wall of the positioning rod 33 and is used to pull the positioning rod 33 to fit against the shaft of the turbine 6.

[0027] Working principle: First, the middle part of the turbine shaft 5 is placed in the clamping assembly 26 of the active clamping mechanism 2, while both ends of the turbine shaft 5 are placed on the two arc-shaped extension clamps 416. During placement, the arc-shaped extension clamps 416 push the ring 41 downward, compressing the spring 46 on the slide column 45. Then, the motor 28 is started, driving the gear ring 25 to rotate through the gear 29. The gear ring 25 drives the adjusting ring 262 to rotate, and the arc-shaped hole 263 on the adjusting ring 262 pushes the slide rod 265, causing multiple clamping rods 264 to move radially synchronously along the positioning block 261, thereby achieving automatic centering and clamping of the turbine shaft 5. Subsequently, the two turbines 6 are placed in the driven clamping mechanisms 4 on both sides respectively. The outer bidirectional screw 411 is rotated to drive the two arc plates 48 to move towards each other. The push rod 49 drives the arc clamping plate 410 to clamp the connecting shaft of the turbine 6. At the same time, the position of the positioning seat 31 is adjusted by the adjusting screw 32 of the positioning mechanism 3, so that the positioning rod 33 automatically fits the turbine shaft under the action of the tension spring 34 to ensure accurate positioning. When the arc-shaped clamping plate 410 of the driven clamping mechanism 4 clamps the turbine 6, the arc-shaped extension clamping plate 416 at its front end is simultaneously clamped at the end of the turbine shaft 5. This design realizes the automatic alignment of the turbine 6 and the turbine shaft 5. During the clamping process, the turbine shaft 5 no longer bears force on the arc-shaped extension clamping plate 416. At this time, during the clamping process, the spring force of the spring 46 will push the support ring 43 to move upward, thereby realizing the self-adjustment process to adapt to the clamping and positioning of turbine shafts 5 with different diameters. Start the welding equipment (not shown in the figure). Insert the welding torch between the two rotating rings 412 to weld the connection between the drive shafts of the turbine shaft 5 and the turbine 6. During welding, rotate the entire turbine shaft 5 to achieve self-deflection, so that the entire active clamping mechanism 2 deflects on the fixed seat 21 via the annular rail 23 to achieve uninterrupted welding. This keeps the welding head fixed and allows for continuous and uniform circumferential welding of the connection between the rotating turbine 6 and the turbine shaft 5.

[0028] After welding is completed, the clamping component 26 of the active clamping mechanism 2 moves in the opposite direction to release the turbine shaft 5, and the bidirectional screw 411 of the driven clamping mechanism 4 reverses to release the turbine 6. By pulling away the turbine shaft 5, the turbine shaft 5 and the turbine 6 can be removed. Here, the diameter of the turbine 6 is smaller than the maximum diameter of the entire clamping area, so the turbine shaft 5 can be easily removed. Under the restoring force of the spring 46, the support ring 43 drives the ring 41 to move upward and reset, so as to facilitate the second replacement of the turbine shaft 5 for clamping and positioning.

[0029] This invention provides an automatic welding device for turbocharger processing. Many methods and approaches exist for implementing this technical solution; the above description is merely a preferred embodiment of the invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention. All components not explicitly stated in this embodiment can be implemented using existing technologies.
