Description

Technical Field

[0001] This invention belongs to the field of welding equipment technology, and in particular relates to a welding error prevention device for welding components of new energy vehicles. Background Technology

[0002] Welding of pipeline components in new energy vehicles is a key process for ensuring vehicle performance and safety. The welding objects cover components such as cooling systems and fuel delivery pipelines. Advanced technologies such as laser welding and TIG welding are commonly used in welding. Laser welding offers concentrated energy and a small heat-affected zone, enabling high-precision welding; TIG welding features a stable arc and high-quality welds. During the welding process, parameters such as current, voltage, and welding speed must be strictly controlled to ensure the strength, sealing, and corrosion resistance of the weld. Simultaneously, rigorous quality inspections, including non-destructive testing, are conducted on the welded components to ensure that each component meets the high standards required for new energy vehicles.

[0003] A Chinese patent application (or patent) with publication number CN220462832U discloses a pipe welding error prevention device, including a base plate, a support column fixedly installed on the surface of the base plate, two sets of electric lifting rods fixedly installed on the surface of the base plate, the two sets of electric lifting rods being electrically connected to a controller, a controller fixedly installed on one side of the support column, and a rotating component set on one side of the support column. By setting the rotating component, the pipe can be firmly fixed under the action of the pipe fixing part. Driven by a motor, it solves the problem that currently, because the pipes being welded are cylindrical, workers need to twist their bodies with the curvature of the pipe to perform welding work, and it needs to be divided into two sections to completely weld a circle, which not only affects the strength and sealing of the pipe, but also increases labor intensity and reduces welding efficiency.

[0004] However, the above-mentioned device still has the following problems during implementation:

[0005] When clamping pipes, only a single pipe can be fixed. However, during welding, it is often necessary to splice and weld two sets of pipes. But the clamp lacks an effective alignment function during the welding process. When workers connect two pipes, slight carelessness can easily lead to eccentricity. Once eccentricity occurs, the uniformity and quality of the weld are difficult to guarantee, which may result in insufficient weld strength, poor sealing, and other problems, seriously affecting the normal operation and overall performance of the subsequent new energy vehicle pipeline system.

[0006] To address these issues, we provide a welding error prevention device for welding components in new energy vehicles. Summary of the Invention

[0034] The technical solutions of the present invention will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present invention, and not all embodiments. Example 1

[0035] Please see Figures 1-9 This invention relates to a welding error prevention device for welding components of new energy vehicles, comprising a base 1, an adjusting ring 2 on the top of the base 1, and a laser welding head 3 installed inside the adjusting ring 2; a detection component 4 on the top of the base 1, comprising a support shell 401 installed on one side of the adjusting ring 2, a pressure sensor 402 installed inside the support shell 401, and a pulley 403 on one side of the support shell 401, the detection component 4 being used to detect the fit of the pipe workpiece; and an adjusting component 5 on the top of the base 1, comprising a first hydraulic rod 501 installed on the top of the base 1, an adjusting shell 502 installed at the output end of the first hydraulic rod 501, and movably connected to the adjusting shell 502. The driven shaft 503 inside the 02, the gear 504 mounted on the surface of the driven shaft 503, and the gear ring 505 mounted on the bottom of the adjusting ring 2 are used to adjust the detection angle of the pipeline through the adjusting component 5; a reset component 6 is provided on the top of the base 1. The reset component 6 includes a processing table 601 mounted on the top of the base 1, a second hydraulic rod 602 mounted inside the processing table 601, a fixed shell 603 set on the top of the processing table 601, a screw 604 movably connected inside the fixed shell 603, a moving block 605 threadedly connected to the surface of the screw 604, and a clamping plate 606 fixedly connected to the top of the moving block 605. The position of the pipeline workpiece is fixed through the reset component 6.

[0036] Specifically: the base 1 provides a stable support platform for the entire device; the adjusting ring 2 flexibly adjusts the position of the laser welding head 3 to adapt to the welding requirements of pipes with different diameters and angles through its rotatable and lifting characteristics; the detection component 4 detects the fit of the two sets of pipe workpieces in real time through the pressure sensor 402 and pulley 403 in the support shell 401 and feeds back the force data to detect eccentricity or misalignment problems; the adjusting component 5 drives the adjusting shell 502 through the first hydraulic rod 501 to drive the gear 504 to mesh with the gear ring 505, so as to realize the rotation and lifting of the adjusting ring 2 to accurately adjust the welding angle and height. Example 2

[0037] Please see Figures 1-9 Based on Embodiment 1, a support shaft 7 is movably connected to the axis of pulley 403. A bracket 8 is fixedly connected to one side of the support shaft 7, and the other side of the bracket 8 extends into the interior of the support housing 401 and is fixedly connected to the pressure sensor 402. The bracket 8 is slidably connected to the inner wall of the support housing 401. Two sets of pulleys 403 and two sets of pressure sensors 402 are provided, respectively contacting the surfaces of two sets of pipe workpieces. One side of the gear ring 505 meshes with the gear 504. The surface of the driven shaft 503 is movably connected to the inner wall of the adjusting housing 502 through the first bearing. An opening is provided at the top of the adjusting ring 2, the width of which is greater than the diameter of the pipe workpiece. Screw 604 A rotating wheel 9 is fixedly connected to one side. The surface of the screw 604 is movably connected to the inner wall of the fixed housing 603 through the second bearing. A clamping groove is opened on one side of the clamping plate 606. The clamping groove is coaxial with the adjusting ring 2. There are eight clamping plates 606. A drive assembly 10 is provided on one side of the adjusting housing 502. The drive assembly 10 includes a drive motor 1010 installed inside the adjusting housing 502, a first pulley 1020 installed at the output end of the drive motor 1010, and a second pulley 1030 installed on the surface of the driven shaft 503. A conveyor belt 1040 is sleeved on the surface of the first pulley 1020 and the second pulley 1030.

[0038] Specifically: The reset assembly 6 drives the clamping plate 606 to move via the second hydraulic rod 602 to fix and fine-tune the position of the pipe workpiece, and achieves uniform distribution of clamping force through the cooperation of the screw 604 and the moving block 605. The pulley 403 transmits the force to the pressure sensor 402 through the support shaft 7 and the bracket 8. The symmetrical design of the two sets of pulleys 403 can simultaneously detect the contact status of the two pipes to improve alignment accuracy. The drive assembly 10 drives the driven shaft 503 to rotate via the drive motor 1010 and the pulley to provide stable power output for the drive gear 504 and the gear ring 505. The sliding connection between the guide ring 11 and the annular guide rail 12 provides guidance support for the rotation of the adjusting ring 2 to enhance motion stability. Example 3

[0039] Please see Figures 1-9Based on Embodiments 1 and 2, guide rail rings 11 are fixedly connected to both sides of the adjusting ring 2. An annular guide rail 12 is slidably connected to the surface of the guide rail ring 11. One side of the annular guide rail 12 is fixedly connected to the adjusting shell 502. A column 13 is fixedly connected to the top of the base 1. A vision inspection probe 14 is fixedly connected to the top of the column 13. A moving plate 15 is fixedly connected to the output end of the second hydraulic rod 602. A sliding rod 16 is slidably connected inside the moving plate 15. The bottom of the sliding rod 16 is fixedly connected to the inner wall of the processing table 601. An adjusting rod 17 is fixedly connected to the top of the moving plate 15. The other end of the adjusting rod 17 passes through the processing table 601 and is fixedly connected to the fixed shell 603. A slider is fixedly connected to the bottom of the moving block 605. The bottom of the slider is slidably connected to the inner wall of the fixed shell 603. A groove is opened on the top of the fixed shell 603.

[0040] Specifically: the visual inspection probe 14 monitors the welding process and pipe alignment status in real time, and assists in calibrating the welding position through image feedback. The moving plate 15 slides along the slide rod 16 under the drive of the second hydraulic rod 602, driving the fixed shell 603 and the clamping plate 606 to move, so as to ensure the linear motion accuracy of the clamping mechanism. The clamping groove of the clamping plate 606 is coaxially designed with the adjusting ring 2, and the eight sets of clamping plates 606 are evenly distributed to provide multi-point fixing force, ensuring that the pipe does not shift during the welding process, thereby solving the alignment problem in pipe welding.

[0041] The working principle of this invention is as follows: The worker places the two sets of pipe workpieces to be welded on the top of the two sets of processing tables 601 and between the two sets of clamping plates 606. The two sets of pipe workpieces are moved relative to each other to fit together. Then, the worker manually rotates the rotating wheel 9. The rotating wheel 9, together with the screw 604, drives the moving block 605 to move. The moving block 605 drives the clamping plate 606 to move, thereby clamping and fixing the pipe workpieces.

[0042] After the pipe is initially clamped and fixed, the first hydraulic rod 501 can be activated. The first hydraulic rod 501, together with the adjusting shell 502, drives the adjusting ring 2 to move. The adjusting ring 2, together with the support shell 401, drives the two sets of pulleys 403 to move upward synchronously, so that the adjusting ring 2 moves to the surface of the two sets of pipe workpieces and the two sets of pulleys 403 contact the two sets of pipe workpieces at the same time.

[0043] Then, the drive motor 1010 is started. The drive motor 1010, together with the first pulley 1020, drives the conveyor belt 1040 to rotate. The conveyor belt 1040 drives the second pulley 1030 to rotate. The second pulley 1030, together with the driven shaft 503, drives the gear 504 to rotate. The gear 504, together with the gear ring 505, drives the adjusting ring 2 to rotate. The adjusting ring 2, together with the adjusting shell 502, drives the pulley 403 to rotate, so that the two sets of pulleys 403 slide on the surfaces of the two sets of pipe workpieces. When the pulleys 403 rotate, together with the support shaft 7 and the bracket 8, the thrust generated by the sliding of the pulleys 403 is transmitted to the pressure sensor 402. When the two sets of pipe workpieces are completely aligned, the thrust on the pulleys 403 is the same. When the pressure values ​​fed back by the two sets of pulleys 403 deviate, it can be determined that there is a deviation in the alignment of the pipes.

[0044] At this time, the rotating wheel 9 can be manually rotated to adjust the position of the clamping plate 606 and adjust the alignment angle of the two sets of pipes. At the same time, the second hydraulic rod 602 can be activated. The second hydraulic rod 602, together with the moving plate 15, drives the adjusting rod 17 to move. The adjusting rod 17 pushes the fixed shell 603 to move, thereby adjusting the docking height of the pipe workpiece, eliminating errors during pipe docking, and improving the welding effect.

[0045] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
