Description

Technical Field

[0001] This invention relates to the field of pipeline welding technology, specifically to a molding mechanism and processing line for an automotive turbocharger inlet and outlet water pipe assembly. Background Technology

[0002] In the field of pipeline welding, the clamping devices of traditional processing methods are mostly fixed structures with poor versatility. The alignment of the pipeline axis and the adjustment of the parallelism of the weld end face rely entirely on the operator's experience. The accuracy is difficult to guarantee by visual inspection or simple tools, which can easily lead to defects such as weld misalignment and edge misalignment, seriously affecting the welding quality. For example, the pipe welding processing device disclosed in Chinese Patent Publication No. CN120115911B uses a servo motor drive, a swing adjustment electric cylinder, and clamping rollers to achieve stable clamping of pipes of different diameters and to accurately adjust the height of the pipe axis and the parallelism of the weld end face. At the same time, the device uses a calibration needle and a high-pressure generator to assist in judging the deviation of the pipe axis through the distribution of the electric arc, which effectively improves the docking accuracy and operating efficiency. To a certain extent, it solves the problems of poor versatility and difficulty in manual adjustment of traditional devices. However, the core improvement of this patent is concentrated on the clamping and fixing, axis alignment and calibration before welding. Its axis correction relies on additional calibration components, which has limitations in terms of flexible adjustment to adapt to different assembly requirements. Moreover, it is impossible to continuously calibrate the equipment during docking, and it is necessary to constantly use the calibration components. The equipment has high precision requirements and it is difficult to fully meet the welding processing needs of specific irregular pipe components such as automotive turbocharger inlet and outlet water pipe assemblies. Summary of the Invention

[0003] To address the aforementioned issues, a molding mechanism and processing line for automotive turbocharger inlet and outlet water pipe assemblies are provided. This mechanism enables dynamic and continuous precision calibration during the docking process without relying on additional calibration components. As the second clamping component moves closer to the first clamping component, the cooperation between the first and second guide parts drives and adjusts the position of the pipe workpiece on the second clamping component in real time, gradually correcting axial deviations. This reduces the requirements for overall equipment installation accuracy, making operation simpler and more efficient. It eliminates the need for repeated manual adjustments, simplifying the operation process and improving docking efficiency.

[0004] To address the problems of existing technologies, this invention provides a molding mechanism for an automotive turbocharger inlet and outlet water pipe assembly, including a base and a first clamping assembly disposed on the base. The first clamping assembly has a first through hole for placing a pipe workpiece and a plurality of first clamping heads equidistantly surrounding the first through hole, and each of the plurality of first clamping heads can slide radially along the first through hole. Each first clamping head is provided with a first guide portion. The base also has a second clamping assembly that can slide along the axial direction of the first through hole, and the second clamping assembly has a first clamping head for placing a pipe workpiece. Two through holes and two second clamping heads, the same number of which correspond one-to-one with the first clamping heads. Multiple second clamping heads can slide radially along the second through holes, and the second clamping heads are elastically connected to the second clamping assembly. Each second clamping head is provided with a second guide portion that matches the first guide portion. When the second clamping assembly moves closer to the first clamping assembly, the corresponding first guide portion on the first clamping assembly and the second clamping assembly cooperate with the second guide portion to drive the sliding of the second clamping head, so that the second clamping assembly and the pipe workpiece clamped on the first clamping assembly are coaxial.

[0005] Preferably, the first guide portion includes a mounting block and a tapered guide hole disposed on the mounting block, and the second guide portion is a tapered guide head that matches the guide hole.

[0006] Preferably, the second clamping component is a disc-shaped mounting base, the second through hole is located in the center of the mounting base, the mounting base is provided with the same number of sliding grooves as the second clamping heads and corresponding to each other, the second clamping heads are slidably mounted on the sliding grooves, the sliding grooves extend radially along the mounting base, and an elastic element is provided between the edge of the mounting base and the second clamping head.

[0007] Preferably, the mounting base is provided with a locking mechanism for locking the sliding position of the second clamping head after the position of the second clamping head has been corrected into place.

[0008] Preferably, the locking mechanism includes clamping pieces correspondingly disposed on both sides of each second clamping head, both clamping pieces extending along the length direction of the slide groove, and the two clamping pieces being able to slide relative to each other.

[0009] Preferably, the locking mechanism includes a drive disk, which is slidably mounted on the mounting base along the axial direction of the second through hole. The drive disk has drive blocks on the side facing the clamping piece that correspond one-to-one with the clamping piece, and the drive blocks and the clamping piece are provided with mutually compatible wedge-shaped mating surfaces.

[0010] Preferably, the second clamping assembly further includes an auxiliary support for supporting the pipe assembly, and an adjustment component for adjusting the distance is provided between the auxiliary support and the second clamping assembly.

[0011] Preferably, the first clamping component is provided with a distance sensor for detecting the real-time distance between the first clamping component and the second clamping component.

[0012] Preferably, the base is provided with a lead screw slide for driving the second clamping assembly to slide.

[0013] A processing line for automotive turbocharger inlet and outlet water pipe assemblies includes a forming mechanism for automotive turbocharger inlet and outlet water pipe assemblies as described above.

[0014] The advantages of this invention compared to the prior art are: 1. In the process of aligning the axis of the pipe workpiece, this invention eliminates the need for additional calibration components, enabling dynamic and continuous precision calibration during the docking process. As the second clamping component approaches, the cooperation between the first and second guide parts drives the position of the pipe workpiece on the second clamping component in real time, gradually correcting the axis deviation. This avoids the tedious operation of repeatedly relying on calibration components, while reducing the requirements for the overall installation accuracy of the equipment. The operation is simpler and more efficient, eliminating the need for repeated manual adjustments. This not only simplifies the operation process and improves docking efficiency but also stably ensures the coaxiality of the two components, providing a reliable positioning basis for subsequent welding. This ensures the sealing performance and structural strength of the welded pipe assembly, meeting the usage requirements of automotive turbocharger inlet and outlet water pipes.

[0015] 2. The present invention, through the setting of the locking mechanism, can fix the position of the second clamping head after it has been corrected, so as to avoid the deviation of coaxiality between the pipe body and the elbow caused by the loosening or sliding of the second clamping head during the welding process, thus ensuring the uniformity of the weld and the welding quality, and meeting the stringent requirements of the automotive turbocharger inlet and outlet water pipe assembly for sealing performance and structural strength.

[0016] 3. This invention, through the provision of an auxiliary support base, provides auxiliary support for the portion of the pipe held by the second clamping assembly that is far from the welding end, preventing the pipe from sagging or bending due to its own length or gravity. Simultaneously, the auxiliary support base moves synchronously with the second clamping assembly, providing continuous and stable support throughout the entire docking and welding process, preventing the pipe from swaying during movement, further ensuring positioning accuracy during welding, and ensuring that the structural strength and sealing performance of the welded pipe assembly meet usage requirements.

[0029] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1 to 6As shown: A molding mechanism for an automotive turbocharger inlet and outlet water pipe assembly includes a base 1 and a first clamping assembly 11 disposed on the base 1. The first clamping assembly 11 has a first through hole 111 for placing a pipe workpiece 2 and a plurality of first clamping heads 112 equidistantly surrounding the first through hole 111. Each of the plurality of first clamping heads 112 can slide radially along the first through hole 111, and each first clamping head 112 has a first guide portion 1121. The base 1 also has a second clamping assembly 12 that can slide along the axial direction of the first through hole 111. The second clamping assembly 12 has a second through hole 111 for placing the pipe workpiece 2. 21 and second clamping heads 122, which are the same number as and correspond one-to-one with the first clamping heads 112. The multiple second clamping heads 122 can slide radially along the second through hole 121, and the second clamping heads 122 are elastically connected to the second clamping assembly 12. Each second clamping head 122 is provided with a second guide portion 1221 that matches the first guide portion 1121. When the second clamping assembly 12 approaches the first clamping assembly 11, the corresponding first guide portion 1121 and second guide portion 1221 on the first clamping assembly 11 and the second clamping assembly 12 cooperate to drive the sliding of the second clamping head 122, so that the second clamping assembly 12 is coaxial with the pipe workpiece 2 clamped on the first clamping assembly 11.

[0031] The pipe workpiece 2 includes an elbow and a pipe body. When the forming mechanism is working, the elbow and pipe body to be welded are first placed in the first through hole 111 of the first clamping assembly 11 and the second through hole 121 of the second clamping assembly 12, respectively. Multiple first clamping heads 112 slide radially along the first through hole 111 to clamp the elbow on the first through hole 111, and multiple second clamping heads 122 slide radially along the second through hole 121 to clamp the pipe body. Since the second clamping heads 122 are elastically connected to the second clamping assembly 12, they can flexibly adapt to the dimensional tolerances of the elbow and the pipe body, ensuring stable clamping of the pipe workpiece 2 without causing damage. Subsequently, the second clamping assembly 12 moves closer to the first clamping assembly 11 along the axial direction of the first through hole 111. During this process, the first guide portion 1121 on the first clamping head 112 gradually contacts and engages with the corresponding second guide portion 1221 on the second clamping head 122. The interaction between the first guide portion 1121 and the second guide portion 1221 generates a radial driving force, causing the second clamping head 122 to slide radially along the second through hole 121, thereby adjusting the position of the tube body on the second clamping assembly 12. As the second clamping assembly 12 continues to move closer, the engagement of the first guide portion 1121 and the second guide portion 1221 gradually corrects the posture of the tube body, gradually aligning the tube body with the welding end axis of the elbow, ultimately achieving coaxial docking of the two, providing a precise positioning basis for subsequent welding.

[0032] In the alignment of the pipe workpiece 2 axis, this mechanism can achieve dynamic and continuous precision calibration during the docking process without relying on additional calibration components. As the second clamping component 12 approaches, the position of the pipe workpiece 2 on the second clamping component 12 can be adjusted in real time through the cooperation of the first guide part 1121 and the second guide part 1221, gradually correcting the axis deviation. This avoids the tedious operation of repeatedly relying on calibration components, while reducing the requirements for the overall installation accuracy of the equipment. The operation is simpler and more efficient, without the need for repeated manual adjustments. It not only simplifies the operation process and improves docking efficiency, but also stably ensures the coaxiality of the two, providing a reliable positioning basis for subsequent welding and forming. This ensures the sealing performance and structural strength of the pipe assembly after welding, meeting the usage requirements of the automotive turbocharger inlet and outlet water pipes.

[0033] By setting multiple first clamping heads 112 and second clamping heads 122, the irregularly shaped elbows and straight pipes are uniformly clamped. Through the elastic connection between the second clamping head 122 and the second clamping assembly 12, it can not only adapt to the dimensional tolerances of the elbows and pipes during the processing, but also provide flexible clamping force for thin-walled pipes, effectively preventing pipe wall damage caused by rigid clamping and ensuring the structural integrity of the pipes.

[0034] Furthermore, based on actual production needs and the specific shapes of the first clamping head 112 and the second clamping head 122, the clamping positions of the elbow and the pipe can be flexibly changed. Precise docking is achieved through the same clamping and guiding correction logic, which greatly improves the versatility and applicability of the mechanism and can adapt to the molding requirements of different models and structures of automotive turbocharger inlet and outlet water pipe assemblies.

[0035] like Figures 3 to 8 As shown: the first guide portion 1121 includes a mounting block 11211 and a tapered guide hole 11212 disposed on the mounting block 11211, and the second guide portion 1221 is a tapered guide head 12211 that matches the guide hole 11212.

[0036] As the second clamping assembly 12 approaches the first clamping assembly 11, the tapered guide head 12211 on the second clamping head 122 gradually inserts into the tapered guide hole 11212 on the first clamping head 112. As the approach continues, the tapered surface of the guide head 12211 and the tapered surface of the guide hole 11212 come into contact and generate a radial force, driving the second clamping head 122 to slide radially along the second through hole 121, thereby adjusting the position of the tube body. Through the continuous engagement of the tapered surfaces, the posture of the tube body is gradually corrected, ultimately aligning the tube body with the welding end axis of the elbow, achieving coaxial connection and providing precise positioning for subsequent welding. It should be noted that the engagement method of the guide is not limited to the combination of the tapered guide hole 11212 and the guide head 12211 described above. Other guide structures such as wedge blocks and wedge grooves, convex slide rails and concave slide rails, etc., can also be used. The core of all these methods is to achieve radial driving and correction through the interaction of the mating surfaces.

[0037] By employing a mating structure between the tapered guide hole 11212 and the guide head 12211, the tapered surface contact ensures a smoother guiding process and a more uniform distribution of radial force. This prevents damage to the clamping head or pipe fittings caused by excessive localized force. Simultaneously, the self-centering characteristic of the tapered surface precisely drives the sliding of the second clamping head 122, ensuring the coaxiality correction accuracy of the pipe body and elbow. This guiding method eliminates the need for additional calibration components, achieving dynamic correction through the clamping head's own engagement during the docking process. This simplifies the operation process and reduces the requirements for equipment installation accuracy. Furthermore, the diverse configurations of the guide section allow for flexible selection based on the structural characteristics of different pipe fittings, enhancing the mechanism's adaptability to various irregular elbows and pipe combinations in automotive turbocharger inlet and outlet water pipe assemblies, and ensuring the sealing performance and structural strength of the welded pipe assembly.

[0038] like Figures 3 to 9 As shown: the second clamping assembly 12 is a disc-shaped mounting base 123. The second through hole 121 is located in the center of the mounting base 123. The mounting base 123 is provided with the same number of sliding grooves 1231 as the second clamping heads 122 and corresponding to each other. The second clamping heads 122 are slidably mounted on the sliding grooves 1231. The sliding grooves 1231 extend radially along the mounting base 123. An elastic element 1232 is provided between the edge of the mounting base 123 and the second clamping head 122.

[0039] The disc-shaped structure of the mounting base 123 provides stable support for the second clamping head 122. The second through hole 121 at the center of the mounting base 123 allows the pipe workpiece 2 to pass through. The radially extending groove 1231 on the mounting base 123 guides the sliding of the second clamping head 122, ensuring that the clamping head moves only radially along the second through hole 121. In its natural state, the elastic element 1232 pushes multiple second clamping heads 122 closer to the center of the second through hole 121. When the pipe workpiece 2 is placed into the second through hole 121, the outer wall of the pipe workpiece 2 will squeeze the second clamping head 122, causing the elastic element 1232 to contract and store elastic potential energy, thus achieving elastic clamping of the pipe body. When the second clamping assembly 12 approaches the first clamping assembly 11, the second clamping head 122 can slide flexibly under the guidance of the groove 1231. With the cooperation of the first guide part 1121 and the second guide part 1221, the position of the pipe body is gradually corrected, ultimately achieving precise docking of the pipe workpiece 2.

[0040] Its beneficial effects are as follows: the disc-shaped mounting base 123, combined with the radial groove 1231, provides a stable and precise sliding guide for the second clamping head 122, avoiding clamping head offset or jamming and ensuring the reliability of radial adjustment; the design of the elastic element 1232 pushing the clamping head towards the center in its natural state can automatically adapt to pipes of different diameters. When the pipe is inserted, the elastic element 1232 is squeezed to achieve adaptive clamping, which not only ensures the uniformity of clamping force, but also buffers the clamping force to protect the thin-walled pipe and avoid damage caused by rigid contact; the approximate coaxial setting of the mounting base 123 and the through hole reduces the accuracy requirements during equipment installation, reduces debugging difficulty and cost, and at the same time, with the guidance of the groove 1231 and the cooperation of the elastic element 1232, the dynamic correction is achieved with the help of the guide part, so that the mechanism can still ensure the docking accuracy of the elbow and the pipe while simplifying the installation requirements, further improving the practicality and adaptability of the mechanism.

[0041] By setting the elastic element 1232, it can automatically adapt to pipe workpieces 2 of different diameters. When the pipe workpiece 2 is placed in, it can achieve flexible clamping by squeezing the elastic element 1232. This can ensure the uniformity of clamping force to stabilize and fix the pipe, and also avoid rigid extrusion damage to thin-walled pipes such as the inlet and outlet water pipes of automobile turbochargers by using the buffering effect of the elastic element 1232, thus protecting the structural integrity of the pipes. Meanwhile, the guide of the slide groove 1231 and the cooperation of the elastic element 1232 mean that the mounting base 123 does not need to be strictly coaxial with the first through hole 111 and the second through hole 121. Initial approximate alignment is sufficient, which greatly reduces the accuracy requirements for equipment installation and debugging, and reduces the preparation time and cost. During the docking process, the second clamping head 122 can slide flexibly along the slide groove 1231, and with the help of the first guide part 1121 and the second guide part 1221, dynamic position correction is achieved. Ultimately, the accurate docking of the pipe workpiece 2 can still be guaranteed, effectively balancing the ease of use and docking accuracy of the equipment. It can also better meet the welding processing requirements of the automotive turbocharger inlet and outlet water pipe assembly, which includes irregular elbows and pipe bodies.

[0042] like Figures 3 to 6 and Figures 8 to 11 As shown: The mounting base 123 is provided with a locking mechanism 124 for locking the sliding position of the second clamping head 122 after the position of the second clamping head 122 has been corrected into place.

[0043] When the pipe workpiece 2 is placed into the second through hole 121 and clamped by the second clamping head 122, the second clamping assembly 12 moves closer to the first clamping assembly 11. Through the cooperation of the first guide part 1121 and the second guide part 1221, the second clamping head 122 is driven to slide radially along the slide groove 1231, gradually correcting the position of the pipe body until it is precisely aligned with the elbow. After the coaxiality of the pipe body and the elbow of the pipe workpiece 2 meets the welding requirements and the position of the second clamping head 122 is stable, the locking mechanism 124 on the mounting base 123 is activated, so that the locking mechanism 124 and the second clamping head 122 form a fixed cooperation, restricting the second clamping head 122 from sliding radially along the slide groove 1231, thereby locking the second clamping head 122 and the clamped pipe body in the corrected precise position, ensuring that the pipe body will not be displaced due to external force or vibration during the subsequent welding process.

[0044] The locking mechanism 124 fixes the position of the second clamping head 122 after the position correction is completed, preventing the coaxiality deviation between the pipe and the elbow due to loosening or sliding of the second clamping head 122 during welding. This ensures the uniformity and quality of the weld, meeting the stringent requirements for sealing performance and structural strength of the automotive turbocharger inlet and outlet water pipe assembly. Furthermore, the locking mechanism 124 only activates after the correction is complete, without affecting the elastic clamping adaptation and guiding correction process of the second clamping head 122. This retains the flexibility and dynamic correction capability of the mechanism for adapting to pipes of different sizes, while strengthening the structural stability during welding through the locking function. This allows the mechanism to further improve the reliability of docking positioning while maintaining ease of use and adaptability, effectively reducing weld defects caused by pipe displacement during welding.

[0045] like Figures 3 to 6 and Figures 8 to 11 As shown: The locking mechanism 124 includes clamping pieces 1241 correspondingly disposed on both sides of each second clamping head 122. Both clamping pieces 1241 extend along the length direction of the slide groove 1231, and the two clamping pieces 1241 can slide relative to each other.

[0046] Before the position of the second clamping head 122 is corrected, the clamping plates 1241 on both sides of the second clamping head 122 are in a relatively separated state, which does not affect the elastic clamping adaptation and position adjustment of the second clamping head 122. When the pipe body and the elbow are precisely aligned and the position of the second clamping head 122 is stable, the clamping plates 1241 on both sides are controlled to slide relative to each other until the inner side of the two clamping plates 1241 is tightly attached to the side wall of the second clamping head 122. The clamping force restricts the radial sliding of the second clamping head 122 along the slide groove 1231, thereby achieving reliable locking of the corrected position of the second clamping head 122 and ensuring that the position of the pipe body does not shift during the subsequent welding process.

[0047] By extending the clamping plates 1241 along the length of the slide groove 1231, the radial sliding stroke of the second clamping head 122 can be perfectly matched. This allows the second clamping head 122 to be precisely clamped and locked by the clamping plates 1241 on both sides at any correction position within the slide groove 1231, significantly improving the adaptability and versatility of the locking mechanism 124 and meeting the needs of different locking positions after correction of pipe workpieces 2 of different sizes. At the same time, the extended clamping plates 1241 provide a large-area contact effect, making the force more even during locking and avoiding damage to the second clamping head 122 or the slide groove 1231 due to excessive local pressure. This further enhances the locking stability and effectively resists the displacement of the second clamping head 122 caused by vibration, external forces, and other factors during welding, ensuring that the coaxiality of the pipe body and the elbow always meets the welding requirements. The locking mechanism of the two clamping plates 1241 sliding relative to each other is simple in structure and easy to operate. It can quickly lock and unlock without interfering with the sliding adjustment function of the second clamping head 122 in the early stage, thus taking into account both the adjustment flexibility and positioning reliability of the mechanism.

[0048] like Figures 3 to 6 and Figures 8 to 11 As shown: The locking mechanism 124 includes a drive disk 1242, which is slidably disposed on the mounting base 123 along the axial direction of the second through hole 121. The drive disk 1242 has a drive block 12421 on the side facing the clamping piece 1241, which corresponds to the clamping piece 1241. The drive block 12421 and the clamping piece 1241 are provided with mutually adaptable wedge-shaped mating surfaces.

[0049] The drive disc 1242 is slidably mounted on the mounting base 123 along the axial direction of the second through hole 121. In the initial state, the drive disc 1242 is away from the mounting base 123, and the wedge-shaped mating surfaces of the drive block 12421 and the clamping pieces 1241 do not compress each other. The clamping pieces 1241 on both sides remain separated, without interfering with the radial sliding and position correction of the second clamping head 122. After the second clamping head 122 completes the position correction of the pipe workpiece 2, the drive disc 1242 is driven to move closer to the mounting base 123. The drive block 12421 moves along with it. The wedge-shaped mating surfaces of the drive block 12421 and the wedge-shaped surfaces of the clamping pieces 1241 come into contact with each other and generate a lateral force. This force converts the axial movement of the drive disc 1242 into the sliding of the clamping pieces 1241, pushing the clamping pieces 1241 on both sides of the second clamping head 122 closer together until the second clamping head 122 is clamped and locked. The reset of clamping plate 1241 relies on the sliding fit of drive block 12421 and the constraint of guide member. When unlocking is required, the drive disk 1242 is pushed away from the mounting base 123, and the squeezing force of the wedge-shaped mating surface between drive block 12421 and clamping plate 1241 disappears. Clamping plate 1241 can accurately reset to the separated state along the guide member without deviation or jamming, ensuring that it does not interfere with the radial sliding and position correction of the second clamping head 122 during the next clamping, thus improving the reliability of the mechanism for repeated use. At the same time, the centralized drive mode of drive disk 1242 can synchronously control the movement of all clamping plates 1241, so that multiple second clamping heads 122 are locked or unlocked at the same time, avoiding positioning deviation caused by the delay of the movement of a single clamping plate 1241, and further ensuring the coaxiality stability of the pipe body and the elbow. This integrated structure, which combines wedge motion, guide sliding, and centralized drive, eliminates the need for complex multi-stage drive components. Its compact layout allows it to fully adapt to the spatial structure of the mounting base 123, enhancing both the ease of operation and precision of the locking mechanism 124. It also better meets the stringent requirements for pipe positioning stability during the welding of automotive turbocharger inlet and outlet water pipe assemblies, ensuring consistent welding quality.

[0050] like Figures 1 to 6 and Figure 10 As shown: The second clamping assembly 12 also includes an auxiliary support base 125 for supporting the pipe assembly, and an adjustment component 1251 for adjusting the distance is provided between the auxiliary support base 125 and the second clamping assembly 12.

[0051] An auxiliary support seat 125 is located on the side of the second clamping assembly 12 away from the first clamping assembly 11. It provides auxiliary support to the portion of the pipe held by the second clamping assembly 12 that is far from the welding end, preventing the pipe from sagging or bending due to its length or gravity. The adjusting assembly 1251 between the auxiliary support seat 125 and the second clamping assembly 12 can adjust the distance between them along the axial direction of the pipe. When the lengths of the pipes to be welded are different, the position of the auxiliary support seat 125 is changed by adjusting the assembly 1251, ensuring that the auxiliary support seat 125 is always in contact with the middle or a suitable position of the pipe, forming a stable support. As the second clamping assembly 12 moves the pipe closer to the first clamping assembly 11, the auxiliary support seat 125 moves synchronously with the second clamping assembly 12, continuously providing support to the pipe and ensuring that the pipe maintains the straightness of its axis during butt jointing and welding, preventing deformation of the pipe from affecting the coaxial butt joint with the elbow. The adjusting component 1251, by adjusting the distance between the auxiliary support base 125 and the second clamping component 12, can accommodate pipes of different lengths, significantly improving the adaptability of the mechanism to various specifications of pipe fittings in the inlet and outlet water pipe assembly of automotive turbochargers. This eliminates the need to replace the dedicated support structure for pipes of different lengths, reducing the operating cost of the equipment. Simultaneously, the synchronous movement of the auxiliary support base 125 with the second clamping component 12 provides continuous and stable support throughout the entire docking and welding process, preventing the pipe from wobbling during movement. This further ensures the positioning accuracy during welding, guaranteeing that the structural strength and sealing performance of the welded pipe assembly meet the usage requirements.

[0052] like Figure 1 As shown: A distance sensor 113 is provided on the first clamping component 11 for detecting the real-time distance between the first clamping component 11 and the second clamping component 12.

[0053] When the second clamping assembly 12 approaches the first clamping assembly 11 along the axis of the first through hole 111, the distance sensor 113 on the first clamping assembly 11 is activated simultaneously to detect and provide real-time feedback on the distance data between the first clamping assembly 11 and the second clamping assembly 12. As the second clamping assembly 12 continues to move, the distance sensor 113 compares the detected real-time distance with the preset welding adaptation distance. When the distance reaches the preset value, the distance sensor 113 sends a signal to control the second clamping assembly 12 to stop moving. At this time, the first guide part 1121 and the second guide part 1221 have completed the pipe posture correction, ensuring that the welding end of the pipe and the elbow is at the optimal docking distance, providing a precise position reference for the subsequent locking mechanism 124 action and welding operation.

[0054] The distance sensor 113 can detect the distance between the two clamping components in real time and accurately, avoiding distance deviations caused by manual judgment or mechanical limits. This prevents the components from getting too close and causing collision damage, and also avoids excessive distance affecting welding quality, ensuring that the welded ends of the pipe and elbow are always in the optimal docking state. The signal feedback from the distance sensor 113 enables the automatic start and stop of the second clamping component 12, reducing manual intervention and improving the automation and consistency of operation. Combined with the guide correction and locking mechanism 124, a complete and precise positioning closed loop is formed. At the same time, this design does not rely on the operator's experience judgment, reducing human error and ensuring the welding accuracy of different batches of pipe components. This further improves the product qualification rate of automotive turbocharger inlet and return water pipe components, meeting the stability and efficiency requirements of mass production.

[0055] like Figures 1 to 4 As shown: The base 1 is provided with a lead screw slide 13 for driving the second clamping assembly 12 to slide.

[0056] The sliding speed and stroke of the second clamping component 12 can be precisely controlled by the lead screw slide 13, effectively avoiding problems such as jamming and shaking that may occur in traditional drive methods. This ensures that the second clamping component 12 moves smoothly along the axial direction, providing a stable moving foundation for the guiding and straightening process of the pipe and elbow, and further improving the accuracy of coaxial docking. Through coordinated operation with the distance sensor 113, the lead screw slide 13 can realize the automated and precise start-stop and stroke control of the second clamping component 12, eliminating the need for manual adjustment. This reduces human error, improves processing efficiency, and adapts to the needs of mass production.
