[0002] At present, the heater core assemblies adopted by many vehicles are equipped with complex heater water pipe assemblies. These water pipe assemblies present irregular bending shapes to effectively connect the heater core with the automobile engine. It should be noted that the heater water pipes adopt an eccentric design inside the assembly to adapt to the complex space layout requirements. However, the connection method between the heater core and the heater water pipes mostly relies on traditional fixed welding technology. In the installation practice, this connection method exposes significant defects: there are no effective fixing measures between the heater core and the heater water pipes, resulting in the heater water pipes being prone to position deviation under the extreme environment of high-temperature brazing, thereby reducing the stability of the overall structure; this problem not only seriously weakens the firmness of the installation, but also greatly increases the difficulty of quality control in the manufacturing process and increases unnecessary cost expenditures.

The heater core water pipe assembly assembly 4 and the tooling plate 3 are connected movably, facilitating adjustment of position and angle to adapt to different assembly requirements. The structure and function of the heater core water pipe assembly assembly 4 are as follows: a support plate 401 is inclined to provide a stable support surface for the heater core 6; one end of the support plate 401 is connected to the tooling plate 3 via a hinge 402.

[0023] Please refer to the following: Figure 2a , 2b and Figure 3 , Figure 4 As an embodiment of this utility model, a dual-axis cylinder 10 is provided below the support plate 401, wherein the cylinder body of the dual-axis cylinder 10 is fixedly connected to the lower end of the support plate 401; a cylinder connecting plate 11 is installed at the top of the piston rod of the dual-axis cylinder 10, wherein the cylinder connecting plate 11 has a "T" shaped structure; the cylinder connecting plate 11 is located at the opening of the "U" shaped limiting groove 7, wherein the lower end of the cylinder connecting plate 11 is fixedly connected to the top of the piston rod, and the upper end of the cylinder connecting plate 11 is located above the support plate 401; an avoidance groove 12 is provided on the side of the support plate 401 near the cylinder connecting plate 11, wherein a buffer pad 13 is provided on the side of the upper end of the cylinder connecting plate 11 near the heater core 6.

[0024] In the above-described scheme, the tooling trolley 1 provides a stable support platform, and the panel 2 above it provides a working surface for subsequent assembly operations; the tooling plate 3 is equipped with a heater core water pipe assembly assembly 4, which is connected to the tooling plate 3 via a movable connection, facilitating adjustment of position and angle; the support plate 401 is inclined and connected to the tooling plate 3 via a hinge 402, allowing the support plate 401 to rotate relative to the tooling plate 3 at a certain angle to adapt to different assembly requirements; the limiting seat 403 above the support plate 401 together form a "U"-shaped limiting groove 7 with an opening on one side, used to stably place and position the heater core 6; a dual-axis cylinder 10 is provided below the support plate 401, wherein the cylinder body of the dual-axis cylinder 10 is fixedly connected to the lower end of the support plate 401, providing... The entire assembly assembly provides a power source; a cylinder connecting plate 11 is installed at the top of the piston rod of the dual-axis cylinder 10. The cylinder connecting plate 11 has a "T" shape and is located at the opening of the "U"-shaped limiting groove 7; the lower end of the cylinder connecting plate 11 is fixedly connected to the top of the piston rod, while the upper end of the cylinder connecting plate 11 is located above the support plate 401 for performing specific assembly actions; in order to accommodate the movement of the cylinder connecting plate 11, a clearance groove 12 is provided on the side of the support plate 401 near the cylinder connecting plate 11 to ensure that the cylinder connecting plate 11 does not interfere with the support plate 401 during movement; a buffer pad 13 is provided on the upper end of the cylinder connecting plate 11 near the heater core 6 to reduce the impact on the heater core 6 during assembly and protect the heater core 6 from damage.

[0025] In use, the heater core 6 is placed in the "U"-shaped limiting groove 7 formed by the limiting seat 403 to ensure that the heater core 6 is stable and accurately positioned. The dual-axis cylinder 10 is activated, which drives the piston rod of the dual-axis cylinder 10 to move the cylinder connecting plate 11. Since the cylinder connecting plate 11 is located at the opening of the "U"-shaped limiting groove 7, it can gradually approach and contact the heater core 6 as the cylinder connecting plate 11 moves. When the cylinder connecting plate 11 contacts the heater core 6, the buffer pad 13 will play a buffering role. This reduces the impact on the heater core 6 and protects it from damage. After the cylinder connecting plate 11 contacts and stabilizes with the heater core 6, the air heater vertical pipe with the water pipe flange 9 is placed at the end of the heater core 6 with the water pipe interface. At the same time, the water pipe flange 9 is inserted into the contour groove 8 opened on the contour seat 405, so that the contour seat 405 provides stable support and positioning for the heater water pipe 16, ensuring that the heater water pipe 16 can be accurately and stably welded and fixed to the water pipe interface of the heater core, which greatly improves work efficiency.

[0026] Please refer to the following: Figure 2a , 2b and Figure 5As an embodiment of the present utility model, the support plate 401 is provided with two sets of laser sensors 14 at one end near the contour seat 405. The laser sensors 14 are fixedly connected to the support plate 401 through the sensor fixing seat 15, and the laser sensors 14 are respectively corresponding to the water pipe interface on the warm air core 6.

[0027] In the above-described scheme, two sets of laser sensors 14 are provided at one end of the support plate 401 near the contour base 405. The laser sensors 14 are firmly connected to the support plate 401 through sensor fixing bases 15. Each set of laser sensors 14 corresponds to the water pipe interface on the heater core 6, which means that the laser sensors 14 can accurately point to and detect the position of the water pipe interface on the heater core 6. The laser sensors 14 can monitor the position of the water pipe interface on the heater core 6 in real time, including the precise position, direction, and any slight positional changes of the interface. Due to the high precision of the laser sensors 14, they can ensure that the heater water pipe 16 and the water pipe interface on the heater core 6 are precisely aligned during the assembly process. The laser sensors 14 also provide a quality control function. If the position of the water pipe interface deviates during the assembly process, the laser sensors 14 can immediately detect it and issue an alarm, thereby preventing assembly errors and quality problems. This not only achieves efficient and precise assembly of the heater core 6 and the heater water pipe 16, but also further improves the quality control level and automation of the assembly process.

[0028] Please refer to the following: Figure 2a , 2b as well as Figure 3 and Figure 5 As an embodiment of this utility model, the angle adjustment component 5 includes a right-angle plate 501, wherein the horizontal end of the right-angle plate 501 is fixedly connected to the tooling plate 3, and the vertical end of the right-angle plate 501 is provided with a long strip groove 502 along its length direction; an adjustment rod 503 is provided above the right-angle plate 501, wherein the lower end of the adjustment rod 503 is provided with a movable shaft 504, and the movable shaft 504 is disposed in the long strip groove 502 and slidably connected thereto; a hinge seat 505 is provided at the upper end of the adjustment rod 503, wherein the hinge seat 505 is fixedly connected to the bottom of the support plate 401, and the hinge seat 505 is hinged to the adjustment rod 503 by a pin.

[0029] In the above-described scheme, the angle adjustment component 5 includes a right-angle plate 501, the horizontal end of which is fixedly connected to the tooling plate 3 to ensure the stability of the entire component; the vertical end of the right-angle plate 501 has a long strip groove 502 along its length, providing a track for the movement of the adjustment rod 503; the lower end of the adjustment rod 503 is provided with a movable shaft 504, which is set in the long strip groove 502 of the right-angle plate 501 and slidably connected to it. This design allows the adjustment rod 503 to move freely in the vertical direction within the groove, thereby adjusting the angle of the support plate 401; the upper end of the adjustment rod 503 is provided with a hinge seat 505, which is fixedly connected to the bottom of the support plate 401. The hinge seat 505 is hinged to the adjustment rod 503 by a pin. This connection method allows the support plate 401 to rotate at a certain angle relative to the adjustment rod 503, further increasing the flexibility of angle adjustment.

[0030] Place the heater core 6 into the "U"-shaped limiting groove 7 formed by the limiting seat 403 to ensure the heater core 6 is stable and accurately positioned. Before assembly begins, ensure that the right-angle plate 501 is firmly connected to the tooling plate 3, and that the movable shaft 504 of the adjusting rod 503 is in its initial position within the slide groove. Simultaneously, check that the connection between the hinge seat 505 and the support plate 401 is secure and that the pin is properly installed. According to assembly requirements, the angle of the support plate 401 relative to the tooling plate 3 can be adjusted by moving the position of the adjusting rod 503 within the slide groove. Because the hinge seat 505 is hinged to the adjusting rod 503, the support plate 401 can be tilted within a certain range to adapt to the assembly requirements of different heater cores 6. When adjusting the angle of the support plate 401... During the process, the laser sensor 14 monitors the position changes of the water pipe interface on the heater core 6 in real time. If the position deviates, it can be corrected by fine-tuning the position of the adjusting rod 503 or the angle of the support plate 401 to ensure that the heater water pipe 16 is precisely aligned with the water pipe interface on the heater core 6. After confirming that the heater water pipe 16 is precisely aligned with the water pipe interface on the heater core 6, the final assembly and fixing operation is performed to firmly connect the heater water pipe 16 to the heater core 6. After the assembly is completed, the laser sensor 14 is used again for quality inspection to ensure that the assembly quality meets the design requirements. At the same time, necessary tests and acceptance work are carried out to ensure that the heater core 6 assembly can work normally and meet the performance requirements of the automotive air conditioning system.
