Description

Technical Field

[0001] This utility model relates to the field of heat pump production and processing technology, specifically a welding device for heat pump production. Background Technology

[0002] A heat pump is a highly efficient energy conversion device that cleverly utilizes the energy contained in the air to generate heat. The condenser is an indispensable main component of a heat pump. Its core function is to transfer the heat absorbed from the low-temperature environment, along with the heat generated by the compressor, to the space that needs to be heated. The condenser's outer shell consists of a cylinder and two end caps, both of which need to be sealed and welded to both ends of the cylinder to form a sealed structure.

[0003] The current welding process for the condenser shell in heat pumps typically involves first limiting the relative positions of the cylinder and end cap, then initially fixing them together by manual spot welding, and finally sending them into a welding machine to complete continuous welding of the weld seam to achieve a sealed connection. This method is not only inconvenient for aligning the cylinder and end cap coaxially, but also has poor welding efficiency, and requires further development and improvement. Utility Model Content

[0004] The purpose of this invention is to provide a welding device for heat pump production, which addresses the problems of inconvenient coaxial alignment of the cylinder and end cap during the welding process of the condenser shell in current heat pumps, as well as the poor welding efficiency.

A collaborative linkage mechanism is arranged between the fixed limiting mechanisms of the rotating support sleeves. The coordinated linkage mechanism includes a U-shaped fixed mounting plate, which is fixedly connected to the outer circumferential surface of the rotating support sleeve. A second rotating shaft is arranged radially along the rotating support sleeve on the U-shaped fixed mounting plate.

A second guide plug-in rod is arranged on the side of the coordinated limiting plate located on the second telescopic device. The second guide plug-in rod is plugged into and connected to the rotating support plate.

[0006] Furthermore, a linear transmission mechanism is provided between the second support rotating seat and the T-shaped support base. The linear transmission mechanism is a transmission mechanism in which a drive motor is equipped with a transmission gear and a transmission rack that mesh.

A first rotating shaft is provided on both the first support rotating seat 2 and the second support rotating seat 3. The two first rotating shafts are coaxially arranged. A rotating support sleeve 4 is provided at the inner side of each of the first rotating shafts. The two rotating support sleeves 4 are coaxially arranged. A drive motor 5 is provided on the outer surface of the horizontal side of the first support rotating seat 2. The output end of the drive motor 5 is connected to one end of the first rotating shaft.

A collaborative linkage mechanism 9 is provided between the fixed limiting mechanisms 8 of the rotating support sleeves 4. The collaborative linkage mechanism 9 includes a U-shaped fixed mounting plate 901, which is fixedly connected to the outer circumferential surface of the rotating support sleeve 4. A second rotating shaft is radially arranged on the U-shaped fixed mounting plate 901 along the rotating support sleeve 4. A rotating support plate 902 is located at the end of the second rotating shaft away from the rotating support sleeve 4. A rotary motor 903 is located inside the U-shaped fixed mounting plate 901, and its output end is connected to one end of the second rotating shaft. A second telescopic device 904 is located at the end of the rotating support plate 902 away from the second rotating shaft. A collaborative limiting plate 905 is installed through the rotating support plate 902 at the output end of the second telescopic device 904. The surface of the collaborative limiting plate 905 is provided with a rubber anti-slip protective layer. A [missing information - likely a design feature] is located on one side of the collaborative limiting plate 905 near the second telescopic device 904. The second guide plug-in rod 906 is plugged into the rotating support plate 902. The rotating motor 903 drives the second rotating shaft to rotate the rotating support plate 902, which can accurately deliver the cooperating limiting plate 905 between the end cap and the cylinder. The second telescopic device 904 pushes the cooperating limiting plate 905 to contact the two synchronously. The rubber anti-slip protective layer on its surface enhances the friction and ensures that the cylinder rotates synchronously with the end cap, which facilitates the welding of the circumferential weld. The second guide plug-in rod 906 ensures that the cooperating limiting plate 905 moves smoothly and accurately. After part of the welding (spot welding) is completed, the cooperating limiting plate 905 can quickly avoid interference with subsequent welding operations through the telescopic movement of the second telescopic device 904 and the rotation driven by the rotating motor 903, which greatly improves the welding continuity and processing efficiency.

Several bullseye balls are embedded in the surface of the supporting rotating rollers 604 to facilitate loading, unloading, and axial movement of the cylinder. The top output end of the lifting device 603 passes through the U-shaped fixed support base 601 and connects to the bottom of the U-shaped lifting support frame 602. By synchronously adjusting the height of the U-shaped lifting support frame 602 through the lifting devices 603 at both ends, the support requirements of cylinders of different specifications can be precisely matched. This, combined with the rotating support sleeve 4, achieves coaxial positioning of the cylinder and the end cap. The supporting rotating rollers 604 and the bullseye balls on the surface of the top of the U-shaped lifting support frame 602 provide stable support for the cylinder and significantly reduce friction during loading, unloading, and axial movement of the cylinder.

The arc-shaped limiting bearing plate 802 is provided with first guide plug-in rods 803 on both sides of the first telescopic device 801. The first guide plug-in rods 803 are plugged into the rotating support sleeve 4. The arc-shaped limiting bearing plate 802 is driven to extend and retract into the rotating support sleeve 4 by the first telescopic device 801 to achieve a circumferential limiting and fixing of end caps of different diameters.

[0018] A linear transmission mechanism 10 is provided between the second support rotating seat 3 and the T-shaped support base 1. The linear transmission mechanism 10 is a transmission mechanism in which a drive motor is equipped with a transmission gear and a transmission rack to drive the second support rotating seat 3 to move laterally. A control device 11 is provided at one end of the T-shaped support base 1. The drive motor 5, welding robot 7, lifting device 603, first telescopic device 801, rotary motor 903, second telescopic device 904 and the drive motor in the linear transmission mechanism 10 are all electrically connected to the control device 11 to control the working status of each drive component. The lifting device 603, the first telescopic device 801 and the second telescopic device 904 are one of electric telescopic rods, hydraulic cylinders or servo electric cylinders. The drive motor 5, the rotary motor 903 and the drive motor in the linear transmission mechanism 10 are all servo motors.

[0019] Working principle: First, the two end caps are installed in the rotating support sleeves on both sides. The first telescopic device in the fixed limiting mechanism drives the arc-shaped limiting bearing plate to move inward, and the end caps are fixed from the inside. Then, the cylinder is placed on the supporting rotating roller of the lifting support mechanism. The height of the U-shaped lifting support frame is adjusted by the lifting device so that the axis of the cylinder coincides with the rotation axis of the two end caps, so as to achieve coaxial positioning of the three.

[0020] Next, the linear transmission mechanism drives the second support rotating seat to move laterally, causing the end cover to fit precisely with the end face of the cylinder. Then, the coordinated linkage mechanism starts to work: the rotary motor drives the rotary support plate to rotate, causing the coordinated limiting plate to rotate to the joint between the end cover and the cylinder. The second telescopic device pushes the coordinated limiting plate forward, so that it makes close contact with both the end cover and the outer surface of the cylinder.

[0021] After positioning is completed, the drive motor drives the rotating support sleeve and end cap to rotate at a constant speed through the first rotating shaft. Under the transmission action of the cooperative limiting plate, the cylinder rotates synchronously. The welding robot then performs preliminary spot welding of the circumferential weld at the connection between the end cap and the cylinder. After completing the preliminary spot welding of part of the weld, the second telescopic device drives the cooperative limiting plate to move backward, and the rotating motor drives the rotating support plate to rotate 90 degrees to avoid interference, so that the welding robot can complete the continuous welding of the remaining weld without interference.
