Description

Technical Field

[0001] This utility model relates to an important structure for welding, and in particular to a welding fixture for an air conditioning air guide ring. Background Technology

[0002] When welding the air guide ring to the outer ring of an air conditioner, the air guide ring is relatively large, making it difficult to fix and align with the outer ring when welding one end to it. In practice, the operator needs to fix the air guide ring to the outer ring first, then weld a portion of it; subsequently, they need to rotate the air guide ring to fix the remaining part to the outer ring, and then continue welding. This entire welding process is labor-intensive and inefficient. Summary of the Invention

[0003] The purpose of this utility model is to provide a welding fixture for an air conditioning air guide ring that can solve at least one of the above problems.

[0004] According to one aspect of the present invention, a welding fixture for an air conditioner air guide ring is provided, including a mounting frame, a guide cylinder and a pressure rod. The guide cylinder is disposed on the mounting frame, and the pressure rod is rotatably connected to the mounting frame. The pressure rod and the guide cylinder are correspondingly arranged. The guide cylinder is a cylinder and is composed of multiple guide blocks. The bottom of the guide block is provided with an adjustment groove, and the guide block is connected to the mounting frame through the adjustment groove.

[0005] The beneficial effects of this utility model are as follows: By providing a guide cylinder, which is cylindrical, the air guide ring can be fitted onto the outside of the guide cylinder, and then the outer ring can be fitted onto the bottom of the air guide ring, thus fixing the air guide ring relative to the outer ring to be welded. Simultaneously, the pressure rod can further compress the air guide ring, preventing it from moving during welding, facilitating welding, greatly saving labor, and improving welding efficiency. The adjustment groove allows for easy adjustment of the guide block's installation position on the mounting frame, thereby adjusting the outer diameter of the guide cylinder. This allows the guide cylinder to be used with air guide rings of different inner diameters, increasing its applicability and facilitating tensioning of the air guide ring, preventing movement during welding and ensuring welding quality.

[0006] In some embodiments, the guide block includes a base plate, a vertical plate, and a top plate. Both the base plate and the top plate are horizontally positioned, with the top plate located above the base plate. The base plate is mounted on a mounting frame, and an adjustment groove is located on the base plate. One end of the vertical plate is fixed to the top plate, and the other end is fixed to the base plate. Thus, the various structures of the guide block ensure that it possesses a certain level of strength.

[0007] In some implementations, both the base plate and the top plate are provided with insertion holes, and the upper and lower ends of the vertical plate are provided with insertion posts that mate with the insertion holes. This facilitates the installation of the vertical plate through the mating of the insertion posts and holes.

[0008] In some implementations, each guide block contains multiple vertical plates. Therefore, the supporting function can be ensured through these multiple vertical plates.

[0009] In some embodiments, both the base plate and the top plate have protrusions on their outer sides, with all protrusions having the same radius of curvature. Therefore, by providing protrusions, the contact area between the entire guide cylinder and the air guide ring can be reduced, facilitating the removal and fitting of the air guide ring from the guide cylinder and reducing the friction between the guide cylinder and the air guide ring.

[0010] In some embodiments, the outer edge of the vertical plate is flush with the outer edge of the corresponding protrusion. Thus, the vertical plate can support the inner wall of the air guide ring, preventing deformation during welding and fixing.

[0011] In some embodiments, a mounting rod is provided on one side of the mounting bracket, and one end of the pressure rod is rotatably connected to the mounting rod. Thus, the mounting rod facilitates the installation of the pressure rod.

[0012] In some embodiments, a crossbar is provided on the outer side of the pressure rod, and the bottom end of the pressure rod is flush with the bottom end of the crossbar. Therefore, by providing the crossbar, the area of ​​the pressure rod pressing down on the air guide ring can be increased, improving the stability of the air guide ring during welding.

[0013] In some embodiments, a welding fixture for an air conditioning air guide ring further includes multiple cylinders, each corresponding to a guide block. The cylinder is located inside the guide tube, its body is fixed to a mounting bracket, and its piston rod is connected to the corresponding guide block. The extension / retraction direction of the piston rod is consistent with the length direction of the corresponding adjusting groove. Therefore, by incorporating cylinders, the guide tube can be easily fixed in the appropriate position to meet different usage requirements.

[0014] In some embodiments, a welding fixture for an air conditioning air guide ring further includes a fixing device. The fixing device includes a rotating and pressing cylinder, a connecting rod, and a pressing rod. The rotating and pressing cylinder is vertically fixed to the other side of the mounting bracket. The connecting rod is connected to the piston rod of the rotating and pressing cylinder, and the pressing rod is connected to the connecting rod, corresponding to the pressing rod. Thus, the fixing device facilitates pressing onto the pressing rod, which is beneficial for further tightening the air guide ring. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] Reference Figures 1-4 A welding fixture for an air conditioner air guide ring includes a mounting frame 1, a guide cylinder 2, and a pressure rod 3. The guide cylinder 2 is mounted on the mounting frame 1, and the pressure rod 3 is rotatably connected to the mounting frame 1. The pressure rod 3 is correspondingly positioned to the guide cylinder 2. The guide cylinder 2 is cylindrical and consists of multiple guide blocks 21. The bottom of each guide block 21 has an adjustment groove 211, through which the guide block 21 is connected to the mounting frame 1. Because of the adjustment groove 211, the guide block 21 can be adjusted along the length of the groove, thereby increasing or decreasing the outer diameter of the guide cylinder 2. This allows it to accommodate air guide rings with different apertures and facilitates tensioning of the air guide ring.

[0021] In use, the welding fixture for the air conditioner air guide ring of this utility model involves placing the air guide ring on the outside of the guide cylinder 2, and then placing the outer ring to be welded to the air guide ring on the bottom outside of the air guide ring. Next, the pressure rod 3 is pressed down, clamping it tightly onto the top of the air guide ring to further prevent movement and complete the fixing of the air guide ring. Welding can then be performed using external welding equipment. Therefore, this fixture greatly facilitates the fixing and welding of the air guide ring, saves labor, and improves welding efficiency.

[0022] The guide block 21 includes a base plate 212, a vertical plate 213 and a top plate 214. The base plate 212 and the top plate 214 are both horizontally arranged. The top plate 214 is located above the base plate 212. The base plate 212 is mounted on the mounting frame 1. The adjustment groove 211 is located on the base plate 212. One end of the vertical plate 213 is fixed to the top plate 214 and the other end is fixed to the base plate 212.

[0023] During installation, the guide block 21 is fixed to the mounting bracket 1 by external bolts passing through the adjustment groove 211 and the mounting bracket 1. When the guide block 21 needs to be adjusted, the corresponding bolts are loosened, the guide block 21 is moved to the corresponding position, and then the bolts are tightened to fix it, which facilitates the adjustment of the position of the guide block 21, that is, facilitates the adjustment of the outer diameter of the guide cylinder 2.

[0024] By providing a vertical plate 213, the entire guide cylinder 2 can have a certain height, which can support the air guide ring along the axial position of the air guide ring and prevent the air guide ring from deforming during the pressing and welding process.

[0025] Both the base plate 212 and the top plate 214 are provided with sockets 215, and both the upper and lower ends of the vertical plate 213 are provided with posts 216. The posts 216 (sockets 216 are inserted into the sockets 215 in the figure, but are not shown) cooperate with the sockets 215. Therefore, the two ends of the vertical plate 213 are fixed between the base plate 212 and the top plate 214 by means of the posts and sockets 215 respectively.

[0026] Each guide block 21 contains multiple vertical plates 213. This ensures the strength of the entire guide block 21 and meets the support requirements for the air guide ring.

[0027] Both the base plate 212 and the top plate 214 have protrusions 217 formed on their outer sides, and the radius of the arc where each protrusion 217 is located is the same.

[0028] The outer edge of the vertical plate 213 is flush with the outer edge of the corresponding protrusion 217.

[0029] When the air guide ring is fitted on the outside of the guide cylinder 2, the outer edges of each protrusion 217 and the vertical plate 213 abut against the inner wall of the air guide ring. Therefore, while ensuring the support of the air guide ring, the contact area between the guide cylinder 2 and the inner wall of the air guide ring is reduced, the friction between the air guide ring and the guide cylinder 2 is reduced, making it easier for the air guide ring to be fitted on the guide cylinder 2 and for the air guide ring to be easily removed from the guide cylinder 2.

[0030] One side of the mounting bracket 1 is provided with a mounting rod 4, and one end of the pressure rod 3 is rotatably connected to one end of the mounting rod 4 via a rotating shaft 7. In actual use, the pressure rod 3 can rotate around the rotating shaft 7. When the air guide ring needs to be fitted onto the guide cylinder 2, external force rotates the pressure rod 3, causing the pressure rod 3 to rotate outward and open; after the air guide ring is fitted onto the guide cylinder 2, the pressure rod 3 rotates towards the guide cylinder 2, causing the pressure rod 3 to press onto the air guide ring, further fixing the air guide ring.

[0031] A crossbar 31 is welded and fixed to the outside of the pressure rod 3, and the bottom end of the pressure rod 3 is flush with the bottom end of the crossbar 31. The crossbar 31 is set perpendicular to the pressure rod 3, which can increase the area of ​​the pressure rod 3 acting on the air guide ring, and facilitate the pressure rod 3 to press the air guide ring tightly.

[0032] This utility model provides a welding fixture for an air conditioner air guide ring, which also includes multiple cylinders 5, each corresponding to a guide block 21. The cylinder 5 is located inside the guide cylinder 2, and its body is fixed to the mounting bracket 1. Its piston rod is connected to the corresponding guide block 21, and the extension / retraction direction of the piston rod is consistent with the length direction of the corresponding adjustment groove 211. By providing the cylinders 5, the piston rods can be pressed against the inner side of the base plate 212. Therefore, when the guide block 21 is adjusted and fixed, to prevent the air guide ring from squeezing the guide cylinder 2 inward and to prevent the guide cylinder 2 from moving inward, the piston rods of the cylinders 5 extend outward, creating a force that pushes the guide block 21 outward. This ensures that the guide cylinder 2 can always keep the air guide ring taut, guaranteeing that the air guide ring is fixed on the guide cylinder 2.

[0033] A welding fixture for an air conditioner air guide ring also includes a fixing device 6. The fixing device 6 includes a rotating downward pressing cylinder 61, a connecting rod 62, and a pressing rod 63. The rotating downward pressing cylinder 61 is vertically fixed on the other side of the mounting bracket 1. The connecting rod 62 is connected to the piston rod of the rotating downward pressing cylinder 61. The pressing rod 63 is connected to the connecting rod 62. The pressing rod 63 corresponds to the pressing rod 3. That is, when the pressing rod 63 rotates on the side of the pressing rod 3, the bottom end of the pressing rod 63 presses against the pressing rod 3.

[0034] When the fixing device 6 is in operation, rotating the pressing cylinder 61 drives the connecting rod 62 to rotate, so that the pressing rod 63 can press against the pressure rod 3, and the pressure rod 3 further presses the air guide ring to prevent the air guide ring from moving during welding. After the air guide ring is welded, rotating the pressing cylinder 61 in the opposite direction causes the connecting rod 62 to drive the pressing rod 63 away from the pressure rod 3, so that the pressure rod 3 can be opened by external force and the air guide ring can be removed.

[0035] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
