Description

Technical Field

[0001] This utility model relates to the field of brazing machine technology, and in particular to a two-station brazing machine. Background Technology

[0002] Traditionally, flame brazing machines typically consist of a flame brazing fixture and a workpiece fixture. During welding, the workpiece fixture holds the workpiece to be welded, while the flame brazing fixture is usually movable for welding. The disadvantage of this type of welding machine is that the position of the flame nozzle and the workpiece fixture may be mismatched, resulting in inaccurate positioning, over-welding of the workpiece, or weak welds, leading to poor welding results.

[0003] Therefore, this application proposes a two-station brazing machine to improve welding performance. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A two-station brazing machine includes a worktable and a positioning assembly fixed on the upper surface of the worktable. The positioning assembly is used to position two workpieces simultaneously. The worktable surface is provided with two sets of welding assemblies for welding the workpieces. The welding positions of the two sets of welding assemblies are adjusted by an adjustment assembly. The adjustment assembly includes a moving assembly for moving the welding gun closer to the workpiece and a lifting assembly for adjusting the height of the welding gun. Multiple welding guns are mounted on the surface of the lifting assembly via two connecting rods.

[0006] In some embodiments, the welding assembly includes a plurality of welding guns, the tail ends of which are connected to a multi-port connector via hoses, and the plurality of welding guns are located on both sides of the workpiece.

[0007] In some embodiments, the positioning assembly includes a mounting beam fixed to the upper surface of the worktable and two positioning fixtures detachably mounted on the surface of the mounting beam.

[0008] In some embodiments, the movable component includes a housing fixed to the upper surface of a workbench and a first threaded post rotating inside the housing, the surface of the first threaded post being threadedly connected to a first movable block, the first movable block sliding on the surface of the housing.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-6 A two-station brazing machine includes a worktable 1 and a positioning component 2 fixed on the upper surface of the worktable 1. The positioning component 2 is used to position two workpieces 7 at the same time. The surface of the worktable 1 is provided with two sets of welding components 3 for welding the workpieces 7. The welding positions of the two sets of welding components 3 are adjusted by the adjusting component 4 respectively. The welding assembly 3 includes multiple welding guns 303. The tail ends of the multiple welding guns 303 are connected to a multi-port connector 302 via hoses. The multiple welding guns 303 are located on both sides of the workpiece 7. The air inlet of the multi-port connector 302 is connected to a pipe connector 301 via hoses. The pipe connector 301 is connected to the gas premixing system.

[0026] Understandably, by placing the workpiece 7 on the surface of the positioning component 2, the welding component 3 welds the workpiece 7. During welding, the gas premixing system mixes the gas with air and then sprays it out through multiple welding guns 303 and ignites it, so that the multiple welding guns 303 heat and weld multiple welding points on the workpiece 7.

[0027] Specifically, the positioning component 2 includes a mounting beam 201 fixed to the upper surface of the workbench 1 and two positioning fixtures 202 detachably mounted on the surface of the mounting beam 201. The two positioning fixtures 202 are mounted on the upper surface of the mounting beam 201 by bolts.

[0028] It is understandable that by setting up the positioning component 2, under the action of the two positioning fixtures 202, it is convenient to place two workpieces 7 at the same time and weld the two workpieces 7 at the same time, thus saving working time.

[0029] Specifically, the adjustment assembly 4 includes a moving assembly 401 for moving the welding gun 303 closer to the workpiece 7 and a lifting assembly 402 for adjusting the height of the welding gun 303. Multiple welding guns 303 are mounted on the surface of the lifting assembly 402 via two connecting rods 403. The moving component 401 includes a housing 4011 fixed to the upper surface of the worktable 1 and a first threaded post 4012 rotating inside the housing 4011. The first threaded post 4012 is driven to rotate by a drive motor, which is fixed to the tail of the housing 4011. A first moving block 4013 is threadedly connected to the surface of the first threaded post 4012, and the first moving block 4013 slides on the surface of the housing 4011.

[0030] It is understandable that by adjusting the position of multiple welding guns 303 by adjusting component 4, different workpieces 7 can be welded. By setting the moving component 401, during welding, the first threaded column 4012 drives the moving block and multiple welding guns 303 to move towards the workpiece 7, moving the welding guns 303 to both sides of the workpiece 7 for welding. After welding, the first threaded column 4012 drives the welding guns 303 away from the workpiece 7, making it easier to pick up the workpiece 7.

[0031] Specifically, the lifting assembly 402 includes a vertical plate 4021 fixed to the upper surface of the first moving block 4013 and two guide rods 4022 vertically fixed to the back of the vertical plate 4021. A second moving block 4023 slides on the surface of the two guide rods 4022. A second threaded post 4024 rotates on the back of the vertical plate 4021. The second threaded post 4024 is threadedly connected to the surface of the second moving block 4023. A handwheel is fixed at the upper end of the second threaded post 4024. A lifting block 4025 slides on the surface of the two guide rods 4022. The lifting block 4025 is located above the second moving block 4023. The lifting block 4025 is movably connected to the second moving block 4023 through a reciprocating assembly 404. Multiple welding guns 303 are installed on the surface of the lifting block 4025 through two connecting rods 403. A multi-port pipe is fixed to the upper surface of the lifting block 4025.

[0032] It is understandable that the second threaded column 4024 is rotated by the handwheel, thereby causing the second moving block 4023 to drive the lifting block 4025 and multiple welding guns 303 to adjust their height to adapt to welding positions at different heights.

[0033] Specifically, an adjusting block 4031 is fixed to the tail end of the connecting rod 403, and a sliding groove 4032 is provided at the end of the lifting block 4025. The adjusting block 4031 slides on the surface of the sliding groove 4032. Multiple mounting holes are provided on the surface of the sliding groove 4032, and an elongated hole is provided on the surface of the adjusting block 4031. The welding gun 303 is fixed to the surface of the connecting rod 403 by a clamp 304. The clamp 304 is existing technology and will not be described in detail.

[0034] It is understandable that by setting the adjusting block 4031 and the slide 4032, the adjusting block 4031 can be adjusted in position on the inner wall of the slide 4032, thereby adjusting the distance between the welding gun 303 and the workpiece 7. Under the action of the elongated hole and the mounting hole, the adjusting block 4031 can be fixed to the surface of the slide 4032 with bolts. By setting the clamp 304, the welding gun 303 can be easily fixed to the surface of the connecting rod 403, and the angle of the welding gun 303 can be adjusted so that it can be accurately oriented towards the welding position.

[0035] Specifically, the reciprocating assembly 404 includes a connecting plate 4041 fixed to the back of the second moving block 4023 and an eccentric wheel 4042 rotating on the surface of the connecting plate 4041. The eccentric wheel 4042 is driven to rotate by a drive motor. Two stops 4043 are fixed to the back of the lifting block 4025. The two stops 4043 are located above and below the eccentric wheel 4042, respectively.

[0036] It is understandable that by setting the reciprocating component 404, the drive motor drives the eccentric wheel 4042 to rotate, causing the eccentric wheel 4042 to rotate eccentrically. Under the action of the two stop blocks 4043, the eccentric wheel 4042 drives the lifting block 4025 to reciprocate up and down on the surfaces of the two guide rods 4022, thereby driving multiple welding guns 303 to reciprocate and swing, increasing the heating range and thus improving the welding effect. When the second moving block 4023 rises and falls, the connecting plate 4041 and the eccentric wheel 4042 drive the lifting block 4025 to rise and fall.

[0037] Specifically, two air blowing pipes 5 are provided on the surface of the workbench 1, and a high-pressure air source is connected to the lower end of the two air blowing pipes 5; Two water tanks 6 are fixed on the surface of the workbench 1.

[0038] It is understandable that by setting up the air blowing pipe 5, the workpiece 7 can be initially cooled by the air blowing pipe 5 after welding is completed; by setting up the water tank 6, after the workpiece 7 is initially cooled, the workpiece 7 is placed in the water tank 6 for thorough cooling.

[0039] In this invention, the workpiece 7 is placed on the surface of the positioning fixture 202. The position of the welding gun 303 is adjusted by the adjusting component 4. The handwheel drives the second threaded column 4024 to rotate, causing the second moving block 4023 to drive the lifting block 4025 and multiple welding guns 303 to adjust their height to accommodate welding positions at different heights. The position of the adjusting block 4031 is adjusted on the inner wall of the slide groove 4032, thereby adjusting the distance between the welding gun 303 and the workpiece 7. With the help of the elongated hole and the mounting hole, the adjusting block 4031 is fixed to the surface of the slide groove 4032 with bolts. With the help of the clamp 304, the welding gun 303 is fixed to the surface of the connecting rod 403, and the angle of the welding gun 303 is adjusted so that it can be accurately oriented towards the welding position. During the welding operation, the first threaded column 4012 drives the moving block and multiple welding guns 303 to move towards the workpiece 7. The welding guns 303 are moved to both sides of the workpiece 7, so that the gas premixing system mixes the gas with air and sprays it out through multiple welding guns 303 for combustion. The multiple welding guns 303 heat and weld multiple welding points on the workpiece 7, and the welding work is carried out. At the same time, the drive motor drives the eccentric wheel 4042 to rotate, so that the eccentric wheel 4042 rotates eccentrically. Under the action of the two stops 4043, the eccentric wheel 4042 drives the lifting block 4025 to move up and down on the surface of the two guide rods 4022, thereby driving the multiple welding guns 303 to swing back and forth, thereby increasing the heating range and improving the welding effect. After welding, the first threaded column 4012 moves the welding guns 303 away from the workpiece 7. Under the action of the air blowing pipe 5, the air blowing pipe 5 performs preliminary cooling on the workpiece 7. After the workpiece 7 is initially cooled by setting up the water tank 6, the workpiece 7 is placed in the water tank 6 for thorough cooling.
