Description

Technical Field

[0001] This utility model relates to the field of exhaust component welding technology, and specifically to an exhaust component welding device. Background Technology

[0002] Exhaust assembly welding equipment is a specialized automated or semi-automated equipment for welding exhaust-related components in various mechanical devices. It is widely used in the automotive, construction machinery, aerospace, and home appliance industries. Its core function is to form a sealed and robust overall structure through precise welding, ensuring stable operation in high-temperature, high-pressure, and corrosive exhaust gas environments.

[0003] Chinese Patent Publication No. CN222327142U discloses a welding fixture for engine exhaust components. This patent, through the setting of a clamping device, allows the engine component to be fitted onto the top of the base during installation, with its central connecting rod placed in the round hole and connected to the base, ensuring the concentricity of the mounting edge and the inner ring. Then, tightening the adjusting screw causes the expansion block to press down into place, pushing the support block outward in the inner wall of the slide groove, fixing the shape of the mounting edge. Finally, tightening the pressing screw further abuts and fixes the pushed-out support block, thus fixing and limiting the mounting seat and mounting edge of the component for easy welding, reducing welding deformation, and improving the quality of welding. At the same time, the expansion operation is simple, requiring only the tightening of the adjusting screw to press the expansion block into place, saving a lot of operation time.

[0004] The adjustment device in the above-mentioned device adjusts the position of the screw hole mounting block by manually rotating the threaded rod. This not only results in low operating efficiency, but also makes the positioning accuracy entirely dependent on the operator's experience. It lacks a mechanical positioning reference and makes it difficult to ensure consistency across multiple devices or multiple installations.

[0005] Based on this, the present invention designs a welding device for exhaust components to solve the above problems. Utility Model Content

A large inner diameter support assembly is installed at the end of the support rod away from the collar, and a small inner diameter support assembly is installed at the middle of the outer side of the support rod.

[0009] In one embodiment, the large inner diameter support assembly includes multiple abutment rods.

The T-shaped slider is locked in the T-shaped groove by a sliding connection. A mounting seat is fixedly mounted on the upper end of the abutment rod away from the support rod, and a first arc-shaped abutment plate is rotatably mounted on the opposite end of the mounting seat.

[0010] In one embodiment, the small inner diameter support assembly includes multiple fixing sleeves, which are fixedly fitted onto the middle of the outer side of the support rod. A rectangular frame is fixedly installed at the ends of the fixing sleeves that are far apart from each other. An L-shaped abutment rod is rotatably installed inside the rectangular frame. The L-shaped abutment rod is located at the lower end of the rectangular frame. A second arc-shaped abutment plate is rotatably installed at the ends of the L-shaped abutment rods that are far apart from each other.

[0011] In one embodiment, the welding mechanism includes a longitudinal electric slide rail, which is fixedly connected to the upper end of a first electric slider.

[0012] In one embodiment, a hydraulic cylinder is fixedly installed at the rear end of the second electric slider, and an abutment block is fixedly installed at the output end of the hydraulic cylinder. A slot is provided at the middle of the front end of the abutment block, and a limiting block is inserted into the rear end of the slot. The limiting block is L-shaped, and a welding head body is fixedly inserted into the upper rear end of the limiting block.

[0013] In one embodiment, a limiting groove is provided at the middle of the upper and lower ends of the slot, and a locking block is fixedly installed at the upper and lower ends of the front end of the limiting block.

During welding, the pressure sensor detects the pressure signal of the limit block in real time. If the pressure exceeds the preset range, the controller can adjust the extension and retraction of the hydraulic cylinder in time to avoid the welding head body from excessively pressing the exhaust component or the distance from the welding head being too far, which would affect the welding quality. The elastic pad can buffer the collision between the limit block and the front end of the slot, and at the same time protect the pressure sensor, thus ensuring the welding quality and extending the service life of the equipment components.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] In one embodiment, please refer to the appendix to the specification. Figure 1-5 A welding device for exhaust components includes a disc 1, a circular electric slide rail 3 fixedly embedded on the outer side of the upper end of the disc 1, a first electric slider 411 slidably installed inside the circular electric slide rail 3, the first electric slider 411 being electrically connected to the circular electric slide rail 3, a controller 5 fixedly installed on the right side of the disc 1, and a plurality of T-shaped grooves 11 arranged in a ring array on the upper end of the disc 1, and further includes: Limiting mechanism 2 is installed at the middle of the upper end of the disc 1. Limiting mechanism 2 is used to center and limit the exhaust assembly. Welding mechanism 4 is installed on the upper end of the first electric slider 411 and is used to weld the exhaust assembly.

[0023] In this embodiment of the utility model, the electrical structure consists of a circular electric slide rail 3, a first electric slider 411, and a controller 5. The circular electric slide rail 3 and the first electric slider 411 are electrically connected and both are controlled by the controller 5. When the equipment is in operation, the exhaust assembly is first placed in the center of the upper part of the disc 1. The exhaust assembly is centered and limited by the limiting mechanism 2. After positioning, the operator starts the circular electric slide rail 3 through the controller 5. The first electric slider 411, which is compatible with the circular electric slide rail 3, slides along the trajectory of the circular electric slide rail 3, thereby driving the welding mechanism 4 mounted on the upper part of the first electric slider 411 to perform a circular motion. During the movement of the welding mechanism 4, the sliding speed and stopping position of the first electric slider 411 can be adjusted by the controller 5 according to the welding requirements of the exhaust assembly, so that the welding mechanism 4 accurately reaches the designated welding position, thereby completing the welding operation of the exhaust assembly. The multiple T-shaped grooves 11 arranged in a circular array on the upper part of the disc 1 provide a sliding mounting base for the components of the subsequent limiting mechanism 2, ensuring the stable execution of the limiting action.

[0024] In one embodiment of this utility model, the controller 5 provides a stable mechanical positioning reference for the welding mechanism 4 by precisely controlling the circular electric slide rail 3 and the first electric slider 411. The T-shaped slide groove 11 on the disc 1 provides a standardized installation and sliding trajectory for the limiting mechanism 2. Combined with the centering limiting function of the limiting mechanism 2, the positioning accuracy of the exhaust assembly during welding is further improved, providing a basic guarantee for the subsequent welding quality.

[0025] In one embodiment, such as Figure 1-5 As shown, this is a preferred embodiment of the present invention: The limiting mechanism 2 includes a servo motor 21 and a lead screw 22. The servo motor 21 is fixedly connected to the middle of the upper end of the disk 1. The lead screw 22 is fixedly connected to the output end of the servo motor 21. A threaded block 23 is threadedly installed on the upper outer side of the lead screw 22. The threaded block 23 is circular in shape. A bearing 24 is fixedly installed on the outer side of the threaded block 23. A collar 25 is fixedly installed on the outer side of the bearing 24. Support rods 26 are rotatably installed on all four ends of the outer side of the collar 25. A large inner diameter support component 27 is installed on the end of the support rod 26 away from the collar 25. A small inner diameter support component 28 is installed on the middle of the outer side of the support rod 26.

[0026] The large inner diameter support assembly 27 includes multiple abutment rods 271. The abutment rods 271 are installed at the lower end of the support rod 26 by a rotatable connection. A T-shaped slider 272 is fixedly installed at the lower end of the abutment rod 271. The T-shaped slider 272 is locked in the T-shaped groove 11 by a sliding connection. A mounting seat 273 is fixedly installed on the upper end of the abutment rod 271 away from the support rod 26. A first arc-shaped abutment plate 274 is rotatably installed at the end of the mounting seat 273 that is away from each other.

[0027] The small inner diameter support assembly 28 includes multiple fixing sleeves 281. The fixing sleeves 281 are fixedly fitted on the middle of the outer side of the support rod 26. A rectangular frame 282 is fixedly installed at the ends of the fixing sleeves 281 that are far apart from each other. An L-shaped abutment rod 283 is rotatably installed on the inner side of the rectangular frame 282. The L-shaped abutment rod 283 is located at the lower end of the inner side of the rectangular frame 282. A second arc-shaped abutment plate 284 is rotatably installed at the ends of the L-shaped abutment rods 283 that are far apart from each other.

[0028] In this embodiment of the invention, when performing the exhaust assembly limiting operation, the servo motor 21 is started by the controller 5. The output end of the servo motor 21 drives the fixedly connected lead screw 22 to rotate. When the lead screw 22 rotates, it drives the threaded block 23, which is threaded on the outside, to move up and down along the axis of the lead screw 22. The threaded block 23 drives the bearing 24 and collar 25, which are fixed on the outside, to move synchronously. The movement of the collar 25 causes the support rod 26, which is rotatably mounted on the four ends of the outside, to deflect at an angle. The abutment rod 271 at the lower end of the support rod 26 slides in the T-shaped groove 11 of the disc 1 through the T-shaped slider 272, which drives the first arc-shaped abutment plate 274 on the mounting base 273 to move outward or inward, adapting to the support and limiting of the large inner diameter exhaust assembly. At the same time, the rectangular frame 282 on the fixed sleeve 281 in the middle of the support rod 26 drives the L-shaped abutment rod 283 to rotate, causing the second arc-shaped abutment plate 284 to move synchronously, thereby achieving the support and limiting of the small inner diameter exhaust assembly. By adjusting the speed and direction of the servo motor 21 using the controller 5, the moving distance of the first arc-shaped abutment plate 274 and the second arc-shaped abutment plate 274 can be precisely controlled.

[0029] In one embodiment of this utility model, a transmission combination of servo motor 21 and lead screw 22, along with precise control by controller 5, is used to achieve automated adjustment of the limit mechanism 2. Compared with traditional manual adjustment, the positioning accuracy is greatly improved, and the operation is convenient and efficient. The integrated large inner diameter support component 27 and small inner diameter support component 28 can adapt to exhaust components of different inner diameter specifications, exhibiting strong versatility and eliminating the need to replace dedicated limit components.

[0030] The sliding engagement between the T-shaped slider 272 and the T-shaped groove 11, as well as the rotational connection of components such as the bearing 24 and the support rod 26, ensure the smoothness and stability of the limiting action. The arc design of the first arc-shaped abutment plate 274 and the second arc-shaped abutment plate 284 can fit tightly against the outer wall of the exhaust assembly, improving the firmness of the limiting action and preventing the components from shifting during welding.

[0031] In one embodiment, such as Figure 1-5 As shown, this is a preferred embodiment of the present invention: The welding mechanism 4 includes a longitudinal electric slide rail 41, which is fixedly connected to the upper end of the first electric slider 411. A second electric slider is slidably mounted at the rear end of the longitudinal electric slide rail 41 and is electrically connected to the longitudinal electric slide rail 41. A hydraulic cylinder 42 is fixedly mounted at the rear end of the second electric slider. An abutment block 43 is fixedly mounted at the output end of the hydraulic cylinder 42. A slot is provided in the middle of the front end of the abutment block 43. A limit block 44 is inserted into the slot at the rear end. The limit block 44 is L-shaped. A welding head body 45 is fixedly inserted into the upper rear end of the limit block 44.

[0032] Limiting grooves 4301 are provided at the middle of the upper and lower ends of the slot. The upper and lower ends of the front end of the limiting block 44 are fixedly installed with locking blocks 441. The locking blocks 441 are movably locked in the limiting grooves 4301. An elastic pad 431 is fixedly installed at the front end of the slot. The elastic pad 431 is rectangular. A pressure sensor 432 is fixedly installed at the middle of the front end of the slot. The pressure sensor 432 is located inside the elastic pad 431. The rear end of the elastic pad 431 abuts against the front end of the limiting block 44.

[0033] In this embodiment of the utility model, the electrical structure includes a longitudinal electric slide rail 41, a second electric slider, and a pressure sensor 432. The longitudinal electric slide rail 41 is electrically connected to the second electric slider, and the pressure sensor 432 is electrically connected to the controller 5. They also work in conjunction with the circular electric slide rail 3 and the first electric slider 411. During welding, the controller 5 first activates the longitudinal electric slide rail 41, driving the second electric slider to move the hydraulic cylinder 42 back and forth, adjusting the position of the welding head body 45. The hydraulic cylinder 42 is then activated, its output end pushing the abutment block 43 to move, bringing the welding head body 45 closer to the welding station. The welding head body 45 is installed in the slot of the abutment block 43 via an L-shaped limiting block 44. The locking block 441 of the limiting block 44 is engaged in the limiting groove 4301, ensuring installation stability. The pressure sensor 432 inside the slot detects the pressure signal at the front end of the limiting block 44 in real time and transmits the signal to the controller 5. When the pressure value exceeds the preset range, the controller 5 can adjust the extension and retraction of the hydraulic cylinder 42 to prevent the welding head body 45 from being excessively pressed or too far away. The elastic pad 431 acts as a buffer between the limiting block 44 and the front end of the slot, and works with the pressure sensor 432 to achieve pressure feedback adjustment. In addition, the first electric slider 411 drives the longitudinal electric slide rail 41 to move along the circular electric slide rail 3 to achieve the ring welding operation.

[0034] In one embodiment of this utility model, the cooperation between the longitudinal electric slide rail 41 and the second electric slider realizes the automatic adjustment of the front and rear positions of the welding head body 45. Combined with the precise extension and retraction of the hydraulic cylinder 42, the position adjustment accuracy of the welding head body 45 is greatly improved, solving the problem of inaccurate positioning in traditional manual adjustment.

[0035] The electrical connection between the pressure sensor 432 and the controller 5 establishes a real-time feedback mechanism for welding pressure, which can adjust the contact force of the welding head body 45 in a timely manner. The elastic pad 431 plays a buffering and protective role, which not only avoids damage to the exhaust assembly and the welding head body 45, but also ensures the stability of welding quality.

[0036] The limiting block 44 is detachably connected to the limiting groove 4301 of the abutment block 43 via the locking block 441, which facilitates the replacement and maintenance of the welding head body 45. The slot design makes the limiting block 44 easy to install, while ensuring the stability of the welding head body 45 during operation, and improving the maintenance efficiency and service life of the equipment.

[0037] The working principle of this utility model is as follows: When the equipment is working, the exhaust assembly is first placed in the middle of the upper end of the disc 1. The servo motor 21 in the limit mechanism 2 is started by the controller 5. The output end of the servo motor 21 drives the lead screw 22 to rotate, driving the threaded block 23 to move axially along the lead screw 22. Then, the bearing 24 drives the collar 25 to move synchronously, causing the support rod 26 on the outer side of the collar 25 to deflect at an angle. The abutment rod 271 at the lower end of the support rod 26 slides in the T-shaped groove 11 of the disc 1 through the T-shaped slider 272, driving the first arc-shaped abutment plate 274 on the mounting base 273 to move to adapt to the limit of the large inner diameter exhaust assembly. At the same time, the middle fixed sleeve 28 of the support rod 26 is fixed. The rectangular frame 282 on 1 drives the L-shaped abutment rod 283 to rotate, causing the second arc-shaped abutment plate 284 to move synchronously to adapt to the limit of the small inner diameter exhaust component, thereby achieving the centering positioning of the exhaust component. After positioning, the controller 5 starts the circular electric slide rail 3, and the first electric slider 411 slides along the circular electric slide rail 3, driving the upper longitudinal electric slide rail 41 to move to the vicinity of the welding station. Then, the controller 5 starts the longitudinal electric slide rail 41, driving the second electric slider to drive the hydraulic cylinder 42 to move back and forth, adjusting the front and back position of the welding head body 45. Then, the hydraulic cylinder 42 is started again, and its output end pushes the abutment block 43 to move, so that the welding head body 45 is close to the welding point.

[0038] During the welding process, the pressure sensor 432 in the slot of the abutment block 43 detects the pressure signal at the front end of the limit block 44 in real time and transmits it to the controller 5. If the pressure exceeds the preset range, the controller 5 adjusts the extension and retraction of the hydraulic cylinder 42 to adjust the abutment force of the welding head body 45. The elastic pad 431 in the slot plays a buffering and protective role. At the same time, the first electric slider 411 continuously drives the longitudinal electric slide rail 41 to slide along the circular electric slide rail 3, so that the welding head body 45 completes the annular welding operation of the exhaust component.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
