Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically to a high-efficiency welding device for automotive air conditioning liquid receiver dryer. Background Technology

[0002] In automotive air conditioning systems, the receiver-dryer plays a crucial role in removing impurities, absorbing excess moisture, storing excess refrigerant, and separating liquid from gas. Therefore, the welding quality of the receiver-dryer directly affects the performance and reliability of the entire air conditioning system. Welding the automotive air conditioning receiver-dryer is a critical process, affecting its structural integrity, sealing, and overall performance. Poor welding can lead to refrigerant leakage, decreased system performance, or even system failure.

[0003] In existing technologies, such automotive air conditioning receiver dryers are generally cylindrical. Welding mainly involves welding the bottom cover and the top cover. In existing technologies, one end of the receiver dryer is clamped and fixed first, and the bottom cover or the top cover is welded. After welding, the receiver dryer is flipped and fixed, and then the other end is welded. This process results in low overall work efficiency. Therefore, an improved high-efficiency welding device for automotive air conditioning receiver dryers is needed to address this problem. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency welding device for automotive air conditioning liquid receiver dryers to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency welding device for an automotive air conditioning liquid receiver dryer, comprising a fixed plate, wherein two fixed plates are provided, and a welding mechanism for welding work is provided on the outer surface of the fixed plate. The welding mechanism includes an annular groove, a rotating gear ring, a driving gear, a driven gear, a transmission gear, and a welding head. The outer surface of the fixed plate is provided with an annular groove, and a rotating gear ring is provided on the outer surface of the fixed plate. A driving gear is movably mounted on the upper end of the rotating gear ring via a rotating shaft on the surface of the fixed plate. Driven gears are movably mounted on both sides of the lower end of the driving gear via rotating shafts on the outer surface of the fixed plate. Transmission gears are movably mounted on both sides of the driven gear via rotating shafts on the surface of the fixed plate. A welding head is fixedly mounted on one side of the rotating gear ring.

[0006] Preferably, the driving gear and the driven gear mesh with each other, and the driven gear and the transmission gear mesh with each other. The driving gear rotates to transmit power to the driven gear, which in turn drives the transmission gear to rotate. This ultimately drives the rotating gear ring and the welding head to rotate 360 ​​degrees, thus enabling 360-degree circumferential welding of the workpiece to be welded.

[0007] Preferably, an electric motor is fixedly installed on one side of the surface of the fixed plate. The power output shaft of the electric motor is connected to the rotating shaft where the drive gear is located. The electric motor can drive the drive gear to rotate. The two drive gears on the two fixed plate surfaces share one electric motor. One electric motor can drive the two rotating gear rings to rotate simultaneously.

[0008] Preferably, the rotating toothed ring is engaged with the annular groove via a slider. The annular groove limits the rotation of the toothed ring, ensuring that it can only rotate around the annular groove and cannot disengage.

[0009] Preferably, limit gears are movably provided on both sides of the lower end of the fixed plate via a rotating shaft. The limit gears mesh with the rotating gear ring, and the limit gears can stabilize the rotating gear ring.

[0010] Preferably, a clamping device is fixedly arranged between the fixing plates. The clamping device clamps the workpiece to be welded in the middle. The clamping mechanism of this device can fix the workpiece to be welded until the welding mechanism performs the welding work. The bottom cover and top cover on both sides of the workpiece to be welded can be temporarily fixed together with adhesive to facilitate the subsequent welding work and prevent the bottom cover and top cover from falling off immediately after welding. Since there are many clamping structures available in the prior art, this application will not elaborate on the specific structure of the clamping device.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model uses an electric motor to drive two driving gears to rotate at once. The driving gears then transmit power to the driven gears, which in turn drive the transmission gears to rotate. This ultimately drives the rotating gear ring and the welding head to rotate 360 ​​degrees, allowing for 360-degree circumferential welding of the workpiece. This device can perform double-end welding at once, enabling the simultaneous welding of the top and bottom covers of the liquid storage dryer, thus greatly improving the processing efficiency of the device.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a high-efficiency welding device for an automotive air conditioning liquid receiver dryer, including a fixed plate 1, of which two are provided. The outer surface of the fixed plate 1 is provided with a welding mechanism for welding work. The welding mechanism includes an annular groove 2, a rotating gear ring 3, a driving gear 4, a driven gear, a transmission gear 6, and a welding head 7. The outer surface of the fixed plate 1 has an annular groove 2. The rotating gear ring 3 is provided on the outer side of the fixed plate 1. The driving gear 4 is movably arranged on the upper end of the rotating gear ring 3 on the surface of the fixed plate 1 through a rotating shaft. The driven gear is movably arranged on both sides of the lower end of the driving gear 4 on the outer surface of the fixed plate 1 through a rotating shaft. The transmission gear 6 is movably arranged on both sides of the driven gear on the surface of the fixed plate 1 through a rotating shaft. The welding head 7 is fixedly arranged on one side of the surface of the rotating gear ring 3.

[0020] The driving gear 4 meshes with the driven gear, and the driven gear meshes with the transmission gear 6. The driving gear 4 rotates to transmit power to the driven gear, which in turn drives the transmission gear 6 to rotate. This ultimately drives the rotating gear ring 3 and the welding head 7 to rotate 360 ​​degrees, thus enabling the workpiece 11 to be welded to undergo 360-degree circumferential welding.

[0021] An electric motor 8 is fixedly installed on one side of the surface of the fixed plate 1. The power output shaft of the electric motor 8 is connected to the rotating shaft where the drive gear 4 is located. The electric motor 8 can drive the drive gear 4 to drive. The two drive gears 4 on the surfaces of the two fixed plates 1 share one electric motor 8. The two rotating gear rings 3 can be driven to rotate simultaneously by one electric motor 8.

[0022] The rotating toothed ring 3 is engaged with the annular groove 2 by the slider. The annular groove 2 can limit the rotating toothed ring 3 so that the rotating toothed ring 3 can only rotate around the annular groove 2 and cannot disengage.

[0023] The lower ends of the fixed plate 1 are movably provided with limit gears 9 on both sides via rotating shafts. The limit gears 9 mesh with the rotating gear ring 3, and the limit gears 9 can stabilize the rotating gear ring 3.

[0024] A clamping device 10 is fixedly arranged between the fixed plates 1. The clamping device 10 clamps the workpiece 11 to be welded in the middle. The clamping mechanism of this device can fix the workpiece 11 to be welded, so that the welding mechanism can carry out the welding work. The bottom cover and top cover on both sides of the workpiece 11 to be welded can be temporarily fixed by adhesive to facilitate the subsequent welding work and prevent the bottom cover and top cover from falling off when welding is performed. Since there are many clamping structures in the prior art, this application will not elaborate on the specific structure of the clamping device 10.

[0025] Working principle: When using this device, the clamping device 10 can fix the workpiece 11 to be welded. At this time, the welding positions at both ends of the workpiece 11 can be aligned with the welding heads 7 on both sides. Then, the motor 8 can drive the two drive gears 4 to rotate at one time. The drive gears 4 transmit power to the driven gears, and the driven gears drive the transmission gears 6 to rotate. In the end, the rotating gear ring 3 and the welding heads 7 can rotate 360 ​​degrees. Thus, the workpiece 11 can be welded 360 degrees. In this way, the device can perform double-end welding at one time. This allows the top and bottom covers of the liquid storage dryer to be welded at the same time, which can greatly improve the processing efficiency of the device.
