Technical Field

[0001] The present invention relates to the technical field of welding jigs, and more particularly, to a welding jig and a welding device. Background Art

[0002] During the production process of air conditioners, the welding process is often used for production and processing of some parts of the air conditioner. However, in the actual welding process, since the existing three-way pipe welding jigs often fix three pipes; therefore, for different three-way pipes in the air conditioner components, the existing welding jigs cannot adjust the jig size according to different pipe sizes. Thus, different welding jigs need to be replaced during the actual welding process, resulting in poor general performance of the welding jig and affecting the welding efficiency and production efficiency. Summary of the Invention

[0003] The problem solved by the present invention: The problem that the shape of the welding jig cannot be adjusted.

[0004] To solve the above problems, an embodiment of the present invention provides a welding jig for an air conditioner, including: a bottom plate, on which a plurality of slots are provided; a first moving member, a part of which is located in the slot; a second moving member, at least a part of which is located in the slot; a support plate assembly, connected to the bottom plate; wherein, at least a part of the first moving member and the second moving member can move in the slot respectively, and at least a part of the support plate assembly can move relative to the bottom plate.

[0005] The setting of the first moving member and the second moving member enables the two connection points of the pipes of the three-way welding jig to change the positions of the two connection points according to the positions of the first moving member and the second moving member. The setting of the support plate member enables the position of the third connection point to be adjusted, reducing the number of times of replacing the welding jig, improving the work efficiency, enabling the welding jig to be adjusted according to different pipes.

[0032] To make the above - mentioned objects, features, and advantages of the present invention more obvious and understandable, the following will describe in detail the specific embodiments of the present invention with reference to the accompanying drawings.

[0033]

First Embodiment

[0034] Refer to Figures 1 to 4 , in a specific embodiment, there is a base plate 110, and a plurality of notches 111 are provided on the base plate 110; a first moving member 120, and a part of the first moving member 120 is located in the notch 111; a second moving member 130, and at least a part of the second moving member 130 is located in the notch 111; a pallet assembly 140, and the pallet assembly 140 is connected to the base plate 110; wherein, at least a part of the first moving member 120 and the second moving member 130 can respectively move in the notch 111, and at least a part of the pallet assembly 140 can move relative to the base plate 110.

[0035] The notch 111 includes a first notch 111, a second notch 111 and a third notch 111. The first notch 111 and the second notch 111 are coaxial. The third notch 111 and the first notch 111 are located on both sides of the base plate 110. A part of the first moving member 120 is located in the first notch 111 and can move along the first notch 111 as a whole. At least a part of the second moving member 130 is located in the second notch 111 and can move along the second notch 111 as a whole. The pallet assembly 140 is located between the third notch 111 and the second notch 111 and has a certain distance from the base plate 110. At least a part of the pallet assembly 140 can move relative to the base plate 110.

[0036] During work, the positions of the 120 and the second moving member 130 can be adjusted according to the positions where the corresponding pipelines need to be installed. First, place the welding tooling on the workbench 410 and fix the welding tooling with fixing screws. Subsequently, according to the pipelines to be installed, adjust the positions of the 120, the second moving member 130, and the pallet, and fix the positions. Connect the corresponding pipelines according to the fixed positions. When different spacings are required, the 120 or the second moving member 130 can be slid and moved to a suitable position for fixing. When the distance from the pallet needs to be changed, a part of the pallet component can be moved to achieve the corresponding effect.

[0037] Preferably, when two pipelines need to be fixed, the three notches 111 can cooperate with each other to form three welding toolings 100 for the cooperation of two pipelines, improving the practicality of the device.

[0038] The settings of the 120 and the second moving member 130 enable the two connection points of the pipelines of the tee welding tooling 100 to change the positions of the two connection points according to the positions of the 120 and the second moving member 130. The setting of the pallet component enables the position of the third connection point to be adjusted, reducing the number of times of replacing the welding tooling 100, improving the work efficiency, and enabling the welding tooling 100 to be adjusted according to different pipelines. The three notches 111 can be paired in pairs to form three toolings for fixing two pipelines, increasing the versatility of the welding tooling 100.

[0039]

Second Embodiment

[0040] In a specific embodiment, the welding tooling 100 includes: a tee joint 300, and the tee joint is provided with three interfaces 320; branch pipes 310, and there are three branch pipes 310. One ends of the three branch pipes 310 are respectively connected to the three interfaces 320. The other ends of two of the three branch pipes 310 are respectively connected to the first moving member 120 and the second moving member 130, and the other end of the remaining one branch pipe 310 is placed above the pallet assembly 140.

[0041] There are usually three branch pipes 310, two of which are respectively connected to the 120 and the second moving member 130, and the other one is placed on the pallet component. The tee joint 300 is provided with three interfaces 320, each branch pipe 310 is respectively connected to one interface 320, and at least part of the branch pipe 310 enters the inside of the tee joint 300.

[0042] During work, the positions of 120 and the second moving member 130 are determined according to the pipeline to be welded. After moving 120 and the second moving member 130 to the corresponding positions and fixing them, one end of each of the two branch pipes 310 is connected to 120 and the second moving member 130 respectively, and the other end is connected to the interface 320 of the three-way joint 300. One end of the third branch pipe 310 is connected to the interface 320 of the three-way joint 300, and the other end is placed on the pallet member. When the position of the pipeline changes, first remove all the branch pipes 310, then adjust the positions of 120 and the second moving member 130. After fixing again, adjust the position of the pallet, and finally reconnect the branch pipes 310 to form a new pipeline. When the length of the branch pipe 310 is sufficient and meets the welding requirements, the branch pipe 310 can be directly moved as a whole within the notch 111 together with 120 or the second moving member 130, and the position of the branch pipe 310 placed on the pallet member can be adjusted accordingly, making the adjustment of the working position more convenient.

[0043] After the branch pipes 310 are respectively connected to the connection points on the welding tooling 100 and then connected to the three-way joint 300 to form a three-way pipeline, the way that the branch pipes 310 move as a whole with 120 and / or the second moving member 130 enables the welding tooling 100 to transform more quickly when adapting to the welding of new three-way components, improving the work efficiency.

[0044]

The nitrogen filling and positioning component can be adjusted left and right relative to the bottom plate 110 within the waist-shaped groove for the positioning of three-way components with different spans. The first positioning block 122 is provided with a connection hole. One end of one of the branch pipes 310 is inserted into the connection hole, and the other end is connected to the three-way joint 300 to ensure that nitrogen can be transmitted to the three-way joint 300 through the branch pipe 310. The nitrogen joint is provided with internal threads, the first positioning block 122 is provided with external threads, and the first positioning block 122 passes through the bottom plate 110 and is threadedly connected to the nitrogen joint, clamping the bottom plate 110 between the nitrogen joint and the positioning block.

[0047] During work, move 120 and the second moving member 130 to the corresponding positions. After connecting the branch pipe 310 to the first positioning block 122, start to supply nitrogen into the branch pipe 310. The bottom plate 110 is clamped between the nitrogen joint and the positioning block to ensure that the entire welding tooling 100 does not shake during nitrogen supply. After the nitrogen supply is completed, weld the corresponding positions to obtain the three-way component accordingly.

[0048] Preferably, the first positioning block 122 is detachably connected to the nitrogen gas joint. When the pipe diameter of the three-way component to be welded is changed, different first positioning blocks 122 can be replaced to ensure the smooth progress of nitrogen filling, guarantee the smooth progress of the welding process, reduce the inconvenience caused by replacing the welding tooling and the workbench 410, and improve work efficiency.

[0049] The setting of the first positioning block 122 makes the connection between the nitrogen filling positioning component and the bottom plate 110 more stable, ensuring that there is no jitter during the process of passing nitrogen gas. The detachable connection of the first positioning block 122 enables the welding tooling to be applicable to various different pipe diameters. The first positioning block 122 is connected to the branch pipe 310 to ensure that nitrogen gas can enter the inside of the three-way joint 300 through the branch pipe 310, prevent the weld metal from reacting with oxygen during the welding process, and at the same time, the welding tightness can be judged according to whether there is gas, which plays a role in quality inspection while ensuring work safety.

The second positioning block 131 passes through the bottom plate 110 and is threadedly connected to the plug 132, and the bottom plate 110 is clamped between the plug 132 and the second positioning block 131.

[0053] During work, move the 120 and the second moving member 130 to the corresponding positions, connect the two ends of one branch pipe 310 to the connection hole and the three-way joint 300 respectively, then connect the plug 132 to the second positioning block 131 to ensure that the nitrogen gas does not escape along the second positioning block 131 after entering the three-way joint 300 from the nitrogen gas joint, and finally perform the welding tooling. After the welding tooling is completed, a three-way component is obtained. When the work is completed, simply rotating can separate the plug 132 from the second positioning block 131, quickly enter the production of the next three-way component, reduce the conversion time, and improve work efficiency.

[0054] The setting of the second positioning block 131 makes the connection between the head positioning component and the bottom plate 110 more stable. The setting of the plug 132 prevents nitrogen from flowing out after entering the three-way joint 300 from the nitrogen filling joint, ensuring that the branch pipe 310 and the inside of the three-way joint 300 are filled with nitrogen during the welding process, guaranteeing the work safety of the welding personnel.

The movable frame 500 passes through the round hole 141a and is connected to the second bracket 141. The setting of the round hole 141a makes the connection between the second bracket 141 and the movable frame 500 more firm, ensuring that when the height of the part of the movable frame 500 increases with the height of the fixed sleeve 220, the second bracket 141 can also be lifted by the corresponding height.

[0063] The setting of the round hole 141a connects the second bracket 141 and the movable frame 500 together, ensuring that the second bracket 141 can be driven to move when the fixed sleeve 220 is moved. The round hole 141a is provided between the first support plate 142 and the second support plate 143, which also limits the moving distance of the second support plate 143 on the second bracket 141, preventing the distance between the first support plate 142 and the second support plate 143 from being too small and causing the branch pipe 310 to be placed not smoothly enough.

[0064]

Seventh Embodiment

[0065] In a specific embodiment, the movable frame 500 further includes: a first bracket 200, the first bracket 200 is vertically arranged on the bottom plate 110; a fixed sleeve 220, the fixed sleeve 220 is sleeved on the first bracket 200; a third bracket 210, the third bracket 210 is connected in cooperation with the fixed sleeve 220, wherein, the support plate assembly 140 is connected to the third bracket 210, and the fixed sleeve 220 can slide relative to the first bracket 200.

[0066] A part of the first bracket 200 is located in the third notch 111. The fixed sleeve 220 is sleeved on the first bracket 200 and can slide relative to the first bracket 200, thereby adjusting the height of the support plate assembly 140 relative to the bottom plate 110. The third bracket 210 is connected to the fixed sleeve 220 through its own thread. The support plate part moves along the direction of the third bracket 210 and can also move along the direction of the first bracket 200 under the drive of the fixed sleeve 220.

[0067] During work, when the length and angle of the tee component need to be adjusted, loosen the screw on the fixing sleeve 220, slide the fixing sleeve 220 to the corresponding position. During the sliding process of the fixing sleeve 220, the height of the third support 210 also rises. The third support 210 is fixedly connected to the second support 141 through the round hole 141a. During the sliding process of the fixing sleeve 220, the height of the second support 141 also changes accordingly. After adjusting the supporting plate to the corresponding position, tighten the screw of the fixing sleeve 220 to make the supporting plate more stable. Then place the branch pipe 310 on the supporting plate, and introduce nitrogen into the branch pipe 310 to complete the welding of the tee joint 300. When the distance between the supporting plate assembly 140 and the first notch 111 and the second notch 111 is insufficient, the supporting plate assembly 140 can be moved along the third support 210 to reach the required distance, ensuring that the welding tooling can adapt to different tee components.

[0068] After moving the first moving part 120 and the second moving part 130 to the corresponding positions and connecting the branch pipe 310, when the position of the supporting plate assembly 140 is too close to the tee component and the branch pipe 310 cannot be placed on the supporting plate assembly 140, the entire supporting plate assembly 140 can be moved along the third support 210 to adjust the supporting plate assembly 140 to a suitable position to place the branch pipe 310. When the height of the tee component needs to be adjusted, the fixing sleeve 220 can be moved. When the fixing sleeve 220 moves on the first support 200, the height of the third support 210 connected to the fixing sleeve 220 also changes accordingly. The third support 210 is connected to the second support 141, and the height of the second support 141 also changes accordingly. The height of the supporting plate sleeved on the second support 141 also changes. The fixing sleeve 220 can be locked at any position on the first support 200 by screws. When moved to the height required by the tee component, tighten the screws, then introduce nitrogen into the branch pipe 310 and weld at the socket position of the tee joint 300 and the branch pipe 310 to obtain the welded tee component.

[0069] The setting of the third support 210 enables the second support 141 to slide along the third support 210, and the supporting plate assembly 140 on the second support 141 also moves with the movement of the second support 141, realizing the movement of the supporting plate assembly 140 in the horizontal direction.

[0070] The setting of the first support 200 and the fixing sleeve 220 enables the second support 141 connected to the fixing sleeve 220 to slide when the fixing sleeve 220 slides on the first support 200, changing the height of the supporting plate assembly 140 connected to the second support 141, enabling the supporting plate assembly 140 to change its height in the vertical direction.

[0071]
