Description

Technical Field

[0001] This utility model relates to the technical field of pipe fitting flatness testing equipment, and in particular to an automotive pipe fitting flatness testing device. Background Technology

[0002] Automotive pipe fittings often need to be connected to other components via flanges, clips, or welding. The flatness of the pipe fittings directly affects the fit of the assembly. If the end face or connection surface of the pipe fitting is uneven, gaps may appear between it and the mating component, potentially leading to air or oil leaks or pressure loss. For welded pipe fittings, uneven contact surfaces can cause uneven distribution of welding stress, resulting in defects such as incomplete welds and cracks, reducing connection strength, and potentially causing breakage after long-term use. To ensure assembly accuracy, prevent pipe fitting connection failures, guarantee fluid transmission efficiency and stability, reduce vibration and noise, and mitigate after-sales risks, it is essential to conduct flatness testing on automotive pipe fittings to ensure their reliability in assembly, function, safety, and durability.

[0003] Chinese utility model patent CN220489952U discloses a device for detecting the flatness of automotive pipe fittings, but this device has the following problems in use:

[0004] First, it can only inspect the circular cross-section in one direction at a time, and cannot inspect the entire outer circumference. When it is necessary to inspect the circular cross-section in a different direction, it must be manually adjusted, resulting in low inspection efficiency.

[0005] Secondly, the device is not applicable to the flatness testing of automotive pipe fittings of different sizes, and therefore lacks versatility. Utility Model Content

[0006] The purpose of this invention is to provide an automotive pipe flatness testing device that can test the outer circumference of the pipe by rotating it, eliminating the need for multiple manual adjustments. It is applicable to the flatness testing of critical automotive parts of various sizes and has high testing efficiency.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a flatness detection device for automotive pipe fittings, including a support mechanism, the support mechanism including a worktable, a placement mechanism provided in the middle of the worktable, a lifting mechanism provided below the placement mechanism, clamping mechanisms for clamping automotive round pipe fittings provided on both sides of the placement mechanism, and a detection mechanism for detecting the flatness of automotive round pipe fittings provided above the placement mechanism.

[0008] The clamping mechanism includes a sliding assembly that is slidably disposed above the worktable, a rotating assembly that is fixedly disposed on the sliding assembly, a push-pull assembly that is fixedly disposed on the rotating assembly, and a tensioning assembly for constraining the automotive round tube that is fixedly disposed on the side of the push-pull assembly near the placement mechanism.

[0009] By adopting the above technical solution, the rotating component rotates, thereby realizing the rotation of the push-pull component and the tensioning component, which drives the round pipe to rotate continuously 360°. In conjunction with the laser scanner of the testing mechanism, the circumference of the pipe can be scanned in all directions.

[0010] The lifting mechanism can adjust the center height of the pipe fitting, aligning the central axis of pipe fittings of different diameters with the clamping mechanism, making it suitable for round pipe fittings of different diameters. The sliding component can adjust the distance between the tensioning components on both sides according to the length of the pipe fitting, making it suitable for round pipe fittings of different lengths. The tensioning component can adapt to the clamping requirements of pipe fittings of different diameters through its own structural changes. The multi-dimensional adjustment allows the device to detect automotive round pipe fittings of various specifications and sizes, significantly improving the applicability of the device. A further feature of this invention is that the placement mechanism includes a placement seat, and the lifting mechanism includes a lifting cylinder fixedly installed below the worktable, with the telescopic shaft of the lifting cylinder passing through the worktable and fixedly connected to the lower part of the placement seat.

[0011] By adopting the above technical solution, the placement seat can effectively prevent round pipe fittings from rolling off, providing a stable foundation for subsequent testing work and reducing testing errors caused by unstable placement. The lifting mechanism can adjust the center height of the pipe fittings, aligning the central axis of pipe fittings of different diameters with the clamping mechanism, making it suitable for round pipe fittings of different diameters.

[0012] A further feature of this invention is that: slide bars are fixedly provided on the upper part of both sides of the workbench, and the sliding assembly includes a slide plate and a slide rail provided on the lower part of the slide plate to slide in cooperation with the slide bars.

[0013] By adopting the above technical solution, the sliding component in the clamping mechanism can slide on the worktable. The adjustment of the position of the sliding component will drive the synchronous movement of the entire clamping mechanism. The ultimate goal is to adjust the spacing of the tensioning components in the clamping mechanisms on both sides according to the length of the automotive round tube, so as to achieve the clamping of automotive round tubes of different lengths.

[0014] A further feature of this invention is that the rotating assembly includes a motor and a rotating drum. A gear is fixed to the end of the output shaft of the motor, and a rack is fixedly connected to the middle position of the outer circumference of the rotating drum. The gear meshes with the rack.

[0015] By adopting the above technical solution, the rotating component is driven by an electric motor to mesh with the rack on the outer circumference of the rotating drum, thereby realizing the rotation of the rotating drum and the tensioning component, and driving the round tube to rotate continuously 360°.

[0016] A further feature of this invention is that the push-pull assembly includes a push-pull cylinder located inside the rotating cylinder, and a tensioning assembly is fixedly connected to the end of the telescopic shaft of the push-pull cylinder.

[0017] By adopting the above technical solution, the push-pull cylinder in the push-pull assembly can push the tensioning assembly into the round tube, thereby achieving precise positioning of the round tube, ensuring that the round tube will not be displaced during the inspection process, and improving the inspection accuracy.

[0018] A further feature of this invention is that the tensioning assembly includes a tensioning cylinder, a column located above the tensioning cylinder, and a retainer located above the column.

[0019] The piston rod of the tensioning cylinder passes through a cylinder mounting plate fixedly connected to the upper end face of the tensioning cylinder. The cylinder mounting plate is fixedly connected to the lower end of the column. The retainer includes a fixing ring fixedly connected to the upper end of the column and a vertical cylinder fixedly set on the upper part of the fixing ring. Several sliding grooves are opened on the fixing ring. Several vertical holes are opened on the side wall of the vertical cylinder. A moving rod passes through the vertical cylinder. The moving rod includes an upper rod and a lower rod. The top end of the piston rod is fixedly connected to the bottom end of the lower rod. Several first connecting positions are fixedly set on the side of the upper rod corresponding to the vertical holes. Several tensioning blocks are set along the outer circumference of the vertical cylinder. The position of the tensioning blocks corresponds to the position of the vertical holes and the number of tensioning blocks is the same as the number of vertical holes. A second connecting position is fixedly set on the tensioning block corresponding to the position of the first connecting position. The tensioning block and the moving rod are connected by a connecting block. The two ends of the connecting block are respectively set with a first mounting position connected to the first connecting position and a second mounting position connected to the second connecting position. A sliding column that slides with the sliding groove is fixedly set at the lower end of the tensioning block.

[0020] By adopting the above technical solution, the tensioning component drives the moving rod through the tensioning cylinder, and drives the tensioning block to expand or contract synchronously along the slide groove through the connecting block, so as to achieve uniform tensioning of the inner wall of the round pipe fitting and avoid local deformation or loosening that may be caused by traditional clamping methods.

[0021] The present invention is further configured as follows: support frames are provided at both ends of the workbench, and crossbeams are fixedly provided on the support frames; the detection mechanism includes a lifting assembly and a scanning assembly located below the lifting assembly; the lifting assembly includes a lifting cylinder fixedly provided in the middle of the crossbeam; a hanging rod is fixedly connected to the end of the telescopic shaft of the lifting cylinder; an electric slide rail is fixedly connected to the bottom end of the hanging rod; and stops are provided at both ends of the electric slide rail; the scanning assembly includes a slider slidably connected to the electric slide rail; and a laser scanner is fixedly connected to the lower part of the slider.

[0022] By adopting the above technical solution, the lifting cylinder in the lifting assembly can drive the laser scanner to lift as a whole. Combined with the adjustment of the center height of the round tube by the pushing mechanism, it can ensure that the laser scanner is always at the optimal detection height that matches the surface of the round tube, avoiding the problem of scanning distance being too far or too close due to the difference in diameter of the round tube, and ensuring the accuracy of the detection data.

[0023] The beneficial effects of this utility model are:

[0024] 1. The rotating component of this application achieves the rotation of the rotating drum and the tensioning component by driving the gear of the electric motor to mesh with the rack on the outer circumference of the rotating drum, thereby driving the round pipe to rotate continuously 360°. With the laser scanner of the inspection mechanism, the circumferential surface of the pipe can be scanned in all directions, breaking through the limitations of traditional fixed angle inspection, ensuring no blind spots in inspection, and fully capturing surface flatness defects.

[0025] 2. The tensioning assembly expands and contracts synchronously through the tensioning blocks, applying a uniform force to the inner wall of the round pipe fitting. This avoids localized deformation or loosening caused by traditional clamping methods, ensuring that the pipe fitting remains undisplaced during testing and protecting it from damage.

[0026] 3. The lifting mechanism can adjust the center height of the pipe fitting, aligning the center axis of pipe fittings of different diameters with the clamping mechanism, making it suitable for round pipe fittings of different diameters; the sliding component can adjust the distance between the tensioning components on both sides according to the length of the pipe fitting, making it suitable for round pipe fittings of different lengths; the tensioning component can adapt to the clamping requirements of pipe fittings of different diameters through its own structural changes. The multi-dimensional adjustment allows the device to detect automotive round pipe fittings of various specifications and sizes, significantly improving the applicability of the device.

[0027] 4. The lifting cylinder in the lifting assembly can drive the laser scanner to lift and lower as a whole. Combined with the adjustment of the center height of the pipe by the pushing mechanism, it can ensure that the laser scanner is always at the optimal detection height that matches the surface of the pipe, avoiding the problem of scanning distance being too far or too close due to the difference in pipe diameter, and ensuring the accuracy of the detection data.

[0048] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. 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.

[0049] like Figures 1 to 4 This utility model embodiment specifically provides an automotive pipe flatness detection device, including a support mechanism 1, the support mechanism 1 including a worktable 101, a placement mechanism 2 for placing an automotive round pipe 4 is provided in the middle of the worktable 101, a lifting mechanism 3 for pushing the placement mechanism 2 to rise is provided below the placement mechanism 2, clamping mechanisms 5 for clamping the automotive round pipe 4 are provided on both sides of the placement mechanism 2, and a detection mechanism 6 for detecting the flatness of the automotive round pipe 4 is provided above the placement mechanism 2.

[0050] Furthermore, the clamping mechanism 5 includes a sliding component 51 that is slidably disposed above the worktable 101, a rotating component 52 that is fixedly disposed on the sliding component 51, a push-pull component 53 that is fixedly disposed on the rotating component 52, and a tensioning component 54 for constraining the automotive round tube 4 that is fixedly disposed on the side of the push-pull component 53 near the placement mechanism 2.

[0051] Furthermore, the placement mechanism 2 includes a placement seat 201 for placing the automotive round tube 4, such as... Figure 2 As shown, the placement seat 201 is arc-shaped, with high sides and low middle, which can effectively prevent the round pipe 4 from rolling off, providing a stable foundation for subsequent testing work and reducing testing errors caused by unstable placement.

[0052] Furthermore, the lifting mechanism 3 includes a lifting cylinder 301 fixedly installed below the worktable 101. The telescopic shaft of the lifting cylinder 301 passes through the worktable 101 and is fixedly connected to the lower part of the placement seat 201. It is used to push the placement seat 201 to rise. For automotive round tube parts 4 of different sizes, the height of the central axis of the round tube parts 4 is different. The placement seat 201 rises to support the automotive round tube parts 4 on it, so that the central axis of the automotive round tube parts 4 coincides with the central axis of the clamping mechanism 5, so as to better constrain the automotive round tube parts 4 and ensure that the device can perform flatness detection on round tube parts 4 of various diameters, thereby improving the versatility and applicability of the device.

[0053] Furthermore, slide bars 511 are fixedly installed on the upper parts of both sides of the workbench 101. The sliding assembly 51 includes a slide plate 512 and a slide rail 513 disposed on the lower part of the slide plate 512 and slidingly engaging with the slide bars 511.

[0054] Specifically, the sliding component 51 in the clamping mechanism 5 can slide on the worktable 101, making it easy to adjust its position according to the length of the round tube 4. Since the sliding component 51 is the basic component of the clamping mechanism 5, the rotating component 52, the push-pull component 53 and the tensioning component 54 are all fixed on the sliding component 51. Therefore, the adjustment of the position of the sliding component 51 will drive the synchronous movement of the entire clamping mechanism 5. The ultimate goal is to adjust the spacing of the tensioning components 54 in the clamping mechanisms 5 on both sides according to the length of the round tube 4 of the automobile, so as to achieve the clamping of round tubes 4 of different lengths and improve the applicability of the device.

[0055] Furthermore, the rotating assembly 52 includes a motor 521 and a rotating drum 522, such as Figure 4 As shown, the rotating drum 522 is located above the motor 521. The output shaft of the motor 521 is fixedly connected to a gear 523. A rack 524 is fixedly installed at the middle position of the outer circumference of the rotating drum 522. The drum is driven to rotate by the meshing of the gear 523 and the rack 524.

[0056] Specifically, the rotating component 52 drives the gear 523 to mesh with the rack 524 on the outer circumference of the rotating drum 522 through the electric motor 521, thereby realizing the rotation of the rotating drum 522 and the tensioning component 54, and driving the round tube 4 to rotate continuously 360°.

[0057] Furthermore, the push-pull assembly 53 includes a push-pull cylinder 531 located inside the rotating cylinder 522, and a tensioning assembly 54 is fixedly connected to the end of the telescopic shaft of the push-pull cylinder 531.

[0058] Specifically, the push-pull cylinder 531 in the push-pull assembly 53 can push the tensioning assembly 54 into the round tube 4, thereby achieving precise positioning of the round tube 4, ensuring that the round tube 4 will not be displaced during the inspection process, and improving the inspection accuracy.

[0059] like Figures 4 to 7 As shown, the tensioning assembly 54 includes a tensioning cylinder 541 fixedly connected to the end of the output shaft of the push-pull cylinder 531, a plurality of columns 542 located above the tensioning cylinder 541, and a retainer 543 located above the columns 542.

[0060] Specifically, the piston rod 544 of the tensioning cylinder 541 passes through the cylinder mounting plate 545 which is bolted to the upper end face of the tensioning cylinder 541. The cylinder mounting plate 545 is bolted to the lower end of the column 542. The column 542 can play a supporting role. The retainer 543 includes a fixing ring 546 which is fixedly connected to the upper end of the column 542 and a vertical cylinder 547 which is fixedly set on the upper part of the fixing ring 546.

[0061] Specifically, the upper end face of the tensioning cylinder 541 is provided with several threaded holes, and the cylinder mounting plate 545 is also provided with several threaded holes corresponding to the positions of the threaded holes of the tensioning cylinder 541. The tensioning cylinder 541 and the cylinder mounting plate 545 are fixedly connected by bolts.

[0062] The cylinder mounting plate 545 has several threaded holes on the circumference of its upper end face, and the column 542 has threaded holes at its bottom. The cylinder mounting plate 545 and the lower end of the column 542 are fixedly connected by bolts. The lower end face of the fixing ring 546 has several grooves that correspond to the position of the column, which serve to limit the position of the column 542.

[0063] The column 542 can provide stable support for the cage 543, so that the cage 543 can be stably positioned above the tensioning cylinder 541, forming the overall structural frame of the tensioning assembly 54.

[0064] The fixed ring 546 has several sliding grooves 548, the side wall of the vertical cylinder 547 has several vertical holes 549, and the moving rod 550 passes through the vertical cylinder 547.

[0065] The movable rod 550 includes an upper rod 551 and a lower rod 552 fixedly connected to the upper rod 551. The top end of the piston rod 544 is engaged with the bottom end of the lower rod 552. Several first connection positions 553 are fixedly provided on the side of the upper rod 551 corresponding to the vertical hole 549.

[0066] Several tensioning blocks 554 are arranged along the outer circumference of the vertical cylinder 547. The positions of the tensioning blocks 554 correspond to those of the vertical holes 549, and the number of tensioning blocks 554 is the same as the number of vertical holes 549. A second connecting position 555 is fixedly arranged on the tensioning block 554 at the position corresponding to the first connecting position 553. The tensioning block 554 and the moving rod 550 are connected by a connecting block 556. One end of the connecting block 556 is provided with a first mounting position 557 that is hinged to the first connecting position 553, and the other end of the connecting block 556 is provided with a second mounting position 558 that is hinged to the second connecting position 555. A sliding column 559 that slides in cooperation with the sliding groove 548 is fixedly arranged at the lower end of the tensioning block 554.

[0067] The first connection bit 553 and the second connection bit 555 are the common connectors available today.

[0068] Specifically, the tensioning assembly 54 drives the moving rod 550 through the tensioning cylinder 541. When the moving rod 550 moves upward, the angle of the connecting block 556 gradually becomes horizontal, and the outer end of the connecting block 556 supports the tensioning block 554 to expand away from the moving rod, thus achieving a tensioning effect. When the moving rod 550 moves downward, the angle of the connecting block 556 gradually becomes vertical, and the outer end of the connecting block 556 drives the tensioning block 554 to move closer to the moving rod 550, thus achieving a contraction effect.

[0069] This achieves uniform tension on the inner wall of the round tube fitting 4, avoiding localized deformation or loosening that may occur with traditional clamping methods.

[0070] The specific working process of the tensioning assembly 54 is as follows: In the initial state, the piston rod 544 of the tensioning cylinder 541 is in a contracted state, and the moving rod 550 moves down accordingly. The connecting block 556 drives the tensioning block 554 to contract inward along the slide groove 548 of the fixed ring 546. The tensioning block 554 is in the minimum diameter state, which is convenient for insertion into the inside of the automotive round tube 4.

[0071] When it is necessary to clamp the round tube 4, the tensioning cylinder 541 is activated, the piston rod 544 extends upward, and pushes the moving rod 550 to move upward as a whole; the first connecting position 553 of the upper section of the moving rod 550 drives the second connecting position 555 of the tensioning block 554 to move synchronously through the connecting block 556.

[0072] Because the sliding pin 559 at the lower end of the tensioning block 554 slides into the groove 548 of the fixing ring 546, and the angle of the connecting block 556 changes as the moving rod 550 rises, the tensioning block 554 expands outward along the groove 548 until it comes into close contact with the inner wall of the round pipe fitting 4, thus achieving uniform tensioning constraint on the pipe fitting.

[0073] After the test is completed, the piston rod 544 of the tensioning cylinder 541 retracts, the moving rod 550 moves down, and the connecting block 556 drives the tensioning block 554 to retract inward along the slide groove 548, releasing the pipe fitting and completing one clamping cycle.

[0074] During the tensioning of the automotive round tube component 4, the coordinated action of the mechanical structure enables the synchronous expansion and contraction of the tensioning block 554, ensuring a uniform force on the inner wall of the round tube component 4 and avoiding localized deformation.

[0075] Furthermore, support frames 102 are provided at both ends of the workbench 101, and crossbeams 103 are fixedly provided on the support frames 102. The detection mechanism 6 includes a lifting assembly 61 and a scanning assembly 62 located below the lifting assembly 61. The lifting assembly 61 includes a lifting cylinder 611 fixedly provided in the middle of the crossbeam 103. A hanging rod 612 is fixedly connected to the end of the telescopic shaft of the lifting cylinder 611. An electric slide rail 613 is fixedly connected to the bottom end of the hanging rod 612. Stops 614 are provided at both ends of the electric slide rail 613. The scanning assembly 62 includes a slider 621 that is slidably connected to the electric slide rail 613. At least one slider 621 is provided on each side of the electric slide rail 613 of the hanging rod 612. A laser scanner 622 is fixedly connected to the lower part of the slider 621.

[0076] The lifting cylinder 611 in the lifting assembly 61 can drive the laser scanner 622 to lift as a whole. Combined with the adjustment of the center height of the round tube 4 by the pushing mechanism 3, it can ensure that the laser scanner 622 is always at the optimal detection height that matches the surface of the round tube 4, avoiding the problem of scanning distance being too far or too close due to the difference in diameter of the round tube 4, and ensuring the accuracy of the detection data.

[0077] The scanning component 62, through the cooperation of the electric slide rail 613 and the slider 621, can drive the laser scanner 622 to move smoothly along the length of the round tube 4. Combined with the circumferential rotation drive of the rotating component 52, it can perform full-length and full-circumference flatness detection on the round tube 4, completely eliminate the detection blind zone, and fully capture the defects such as unevenness and bending on the surface of the round tube 4.

[0078] The precise transmission of the electric slide rail 613, combined with the limiting stop 614, enables the uniform speed movement and positioning control of the laser scanner 622, ensuring the continuity and consistency of the scanning data and improving the accuracy level of flatness detection. The height adjustment of the lifting cylinder 611 and the horizontal movement of the slider 621 can be automated through program control, eliminating the need for manual intervention to adjust the scanning position. This significantly shortens the auxiliary time for single-piece inspection, making it suitable for the high-efficiency inspection needs of batch round pipe parts 4, while reducing the error risk caused by manual operation.

[0079] The electric slide rail 613 and slider 621 are existing technologies. The main body of the electric slide rail 613 is a high-precision aluminum alloy track, which integrates a transmission mechanism and a drive motor (the internal details are omitted in the figure). After receiving the control signal, the motor converts the power into the linear motion of the slider 621 through the rotation of the lead screw or belt drive. The slider 621 and the electric slide rail 613 are in contact through bearings to ensure low friction and high stability.

[0080] The control system adjusts the motor speed and direction via pulse signals to precisely control the slider's movement speed and position. End stops 614 provide mechanical limits, working in conjunction with electronic sensors to form a double protection system, preventing the slider from overtraveling. When inspecting the circular tube 4, the motor drives the slider 621, which in turn moves the laser scanner 622 along the track at a constant speed. Combined with the tube's rotation, this achieves full-surface scanning. Its automated control characteristics ensure continuous and consistent scanning data, meeting the requirements for high-precision inspection.

[0081] The laser scanner 622 is existing technology. In this automotive pipe flatness inspection device, it mainly emits a laser beam to irradiate the surface of the round pipe 4, receives the reflected beam, and calculates the propagation time difference or phase difference to accurately capture the three-dimensional coordinate data of the surface of the round pipe 4. Combined with the movement of the electric slide rail 613 and the rotation of the round pipe 4, the overall contour of the round pipe 4 can be quickly scanned, and surface morphology parameters can be generated in real time to determine whether there are uneven defects such as dents, bends, etc. Its high resolution and fast response characteristics can ensure the accuracy and efficiency of the inspection. At the same time, in conjunction with scanners deployed at multiple positions, it can realize the all-round inspection of pipes of different diameters and lengths, providing objective data support for flatness determination.
