Description

Technical Field

[0001] This utility model relates to the field of manifold welding fixtures, and in particular to a welding fixture for an automotive air conditioning condenser manifold. Background Technology

[0002] The air conditioning condenser manifold is an important component of the air conditioning system. Its main function is to transfer heat from the cooling process to the external environment to achieve a cooling effect. The design and manufacturing quality of the manifold directly affects the performance and efficiency of the entire air conditioning system. The air conditioning condenser manifold requires a welding process during production, and automotive air conditioning condenser manifold welding fixtures are needed for welding.

[0003] According to the description in the patent application CN220445487U, "This utility model discloses a welding fixture for an automotive air conditioning condenser manifold, relating to the field of welding fixtures. The welding fixture includes a workbench body, a rotator on the outer surface of the workbench body, a welding pen on the outer surface of the workbench body, a clamping plate slidably connected to the outer surface of the workbench body, and a clamping mechanism on the outer surface of the clamping plate for conveniently clamping the welding pen. The clamping mechanism includes a rotating plate rotatably connected to the outer surface of the clamping plate, the welding pen being disposed on the outer surface of the clamping plate, and the outer surface of the rotating plate abutting against the outer surface of the welding pen."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In use, this utility model involves pushing a push plate, which in turn causes a sliding plate to slide on the outer surface of a sliding rod. The welding pen then contacts the outer surface of the manifold as the sliding plate moves. By using the sliding plate and clamping plate, the welding pen can be stably delivered to the outer surface of the manifold for welding. However, during welding, the position of the welding gun needs to be adjusted depending on the welding location. Because the range of motion of the welding gun is small, it cannot effectively weld large parts during welding adjustments, thus limiting welding efficiency. Therefore, an improved welding fixture for automotive air conditioning condenser manifolds is needed to solve these problems. Utility Model Content

[0006] To overcome the problem that the welding fixture for automotive air conditioning condenser manifolds requires adjusting the position of the welding gun to weld different parts during the welding process, the limited range of motion of the spray gun makes it difficult to effectively weld large parts, thus limiting the welding efficiency.

[0007] The technical solution of this utility model is as follows: a welding fixture for an automotive air conditioning condenser manifold, including a welding base, a threaded rotating rod and a rotating fixing assembly, a support connecting seat fixedly connected to the top of the welding base, a fixing base fixedly connected to the bottom of the welding base, a pusher provided inside the support connecting seat, a fixer fixedly connected to the top of the welding base, a support fixing seat fixedly connected to the top of the welding base, a welding torch provided inside the welding base, a fixing assembly provided inside the support connecting seat, a threaded rotating rod rotatably connected inside the welding base, a rotating handle fixedly connected to the right side of the threaded rotating rod, a sliding threaded block threadedly connected to the threaded rotating rod, and a support connecting plate fixedly connected to the top of the sliding threaded block.

[0008] Preferably, the welding base has a groove at the corresponding position of the sliding threaded block, and the sliding threaded block slides inside the groove.

[0010] Preferably, the sliding limit plate has a groove at the corresponding position of the sliding limit seat, and the sliding limit plate slides outside the sliding limit seat through the groove.

[0011] Preferably, the second extrusion plate has a groove at the corresponding position of the fixed connecting column, and the second extrusion plate slides outside the fixed connecting column through the groove.

[0012] Preferably, the rotating fixing assembly includes a drive motor, which is located on the left side of the support connecting seat. The output end of the drive motor is fixedly connected to a first rotating shaft, which is rotatably connected inside the support connecting seat. A first gear is fixedly connected to the outside of the first rotating shaft. A second rotating shaft is rotatably connected inside the support connecting seat.

A fixing limit block is slidably connected inside the fixing pawl and meshes with the front of the rotating adjusting disc.

[0013] Preferably, the fixed claw disc has a groove at the corresponding position of the fixed limit block, and the drive motor slides inside the groove.

[0014] The beneficial effects of this utility model are as follows: Compared with the welding fixture for automotive air conditioning condenser manifolds, the rotation of the handle drives the threaded rotating rod to rotate inside the welding base. The rotation of the threaded rotating rod, through the threaded connection between the threaded rotating rod and the sliding threaded block, drives the support connecting plate to move left and right inside the welding base. The movement of the welding base allows the welding gun to be adjusted in multiple directions, which provides comprehensive adjustment of the welding gun and improves the welding efficiency. This effectively prevents the limitation of welding large parts caused by the small range of motion of the spray gun. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-5 This utility model provides an embodiment of a welding fixture for an automotive air conditioning condenser manifold, including a welding base 1, a threaded rotating rod 801, and a rotating fixing assembly. A support connecting seat 2 is fixedly connected to the top of the welding base 1, and a fixing base 3 is fixedly connected to the bottom of the welding base 1. A pusher 4 is disposed inside the support connecting seat 2. A fixing device 5 is fixedly connected to the top of the welding base 1, and a support fixing seat 6 is fixedly connected to the top of the welding base 1. A welding torch 7 is disposed inside the welding base 1. The fixing assembly is disposed inside the support connecting seat 2. The threaded rotating rod 801 is rotatably connected inside the welding base 1. A rotating handle 802 is fixedly connected to the right side of the threaded rotating rod 801. A sliding threaded block 803 is threadedly connected to the threaded rotating rod 801. A support connecting plate 804 is fixedly connected to the top. By turning the rotating handle 802 by hand, the rotation of the rotating handle 802 drives the threaded rotating rod 801 to rotate inside the welding base 1. The rotation of the threaded rotating rod 801, and the threaded connection between the threaded rotating rod 801 and the sliding threaded block 803, causes the sliding threaded block 803 to slide inside the welding base 1. The sliding of the sliding threaded block 803 drives the welding torch 7 set on the top of the support connecting plate 804 to perform welding work on the position to be welded. The welding base 1 has a groove at the corresponding position of the sliding threaded block 803. The sliding threaded block 803 slides inside the groove. The groove at the corresponding position of the sliding threaded block 803 inside the welding base 1 limits the sliding threaded block 803 when it slides in the groove.

[0023] Please see Figures 2-3In this embodiment, a sliding limiting seat 805 is fixedly connected to the top of the supporting connecting plate 804. A sliding limiting plate 806 is slidably connected to the outside of the sliding limiting seat 805. A push rod 807 is fixedly connected to the front of the sliding limiting plate 806. A connecting fixing seat 808 is fixedly connected to the top of the sliding limiting plate 806. A first pressing plate 809 is fixedly connected to the inside of the connecting fixing seat 808. A fixing connecting post 810 is fixedly connected between the first pressing plate 809 and the connecting fixing seat 808. A limiting ring 811 is slidably connected to the outside of the fixing connecting post 810. A return spring 812 is fixedly connected between the limiting ring 811 and the connecting fixing seat 808. A second pressing plate 813 is fixedly connected to the bottom of the return spring 812. The second pressing plate 813 is slidably connected to the fixing plate 804. Outside the connecting post 810, the second pressing plate 813 at the bottom of the return spring 812 is pushed by the return spring 812 to fix the welding torch 7. The sliding limit plate 806 has a groove at the corresponding position of the sliding limit seat 805. The sliding limit plate 806 slides outside the sliding limit seat 805 through the groove. The groove inside the sliding limit plate 806 corresponding to the position of the sliding limit seat 805 limits the sliding limit plate 806 when it slides. The second pressing plate 813 has a groove at the corresponding position of the fixed connecting post 810. The second pressing plate 813 slides outside the fixed connecting post 810 through the groove. The groove inside the second pressing plate 813 corresponding to the position of the fixed connecting post 810 limits the second pressing plate 813 when it slides.

[0024] Please see Figures 4-5In this embodiment, the rotating fixing assembly includes a drive motor 901, which is disposed on the left side of the support connecting seat 2. A first rotating shaft 902 is fixedly connected to the output end of the drive motor 901. The first rotating shaft 902 is rotatably connected inside the support connecting seat 2. A first gear 903 is fixedly connected to the outer side of the first rotating shaft 902. A second rotating shaft 904 is rotatably connected inside the support connecting seat 2. A second gear 905 is fixedly connected to the outer side of the second rotating shaft 904, meshing with the outer side of the first gear 903. A fixing pawl 906 is fixedly connected to the right side of the second rotating shaft 904. An adjusting knob groove 907 is rotatably connected inside the fixing pawl 906. A rotating bevel gear 908 is fixedly connected to the inner side of the adjusting knob groove 907. The rotating bevel gear 908 is rotatably connected to the first gear 903. Inside the fixed claw disk 906, a rotating adjusting disk 909 is rotatably connected. The rotating adjusting disk 909 is meshed with the outside of the rotating bevel gear 908. Inside the fixed claw disk 906, a fixed limiting block 910 is slidably connected. The fixed limiting block 910 is meshed with the front of the rotating adjusting disk 909. A drive motor 901 drives the first rotating shaft 902 to rotate. The first gear 903 on the first rotating shaft 902 meshes with the second rotating shaft 904, driving the second gear 905 to rotate. The fixed claw disk 906 has a groove at the corresponding position of the fixed limiting block 910. The drive motor 901 slides inside the groove. The groove inside the fixed claw disk 906 corresponding to the position of the fixed limiting block 910 limits the fixed limiting block 910 when it slides in the groove.

[0025] During operation, the manifold is placed inside the fixed limiting block 910. Twisting the adjusting knob 907 causes the rotating bevel gear 908 to rotate inside the fixed claw disk 906. The rotation of the bevel gear 908 causes the rotating adjusting disk 909 to rotate, which in turn causes the fixed limiting block 910 to extend and retract inwards and outwards, thus squeezing and fixing the manifold. The pusher 4 limits the other end of the manifold, the supporting fixing seat 6 provides support, and the fixing device 5 secures the manifold. The drive motor 901 drives the first rotating shaft 902 to rotate. The rotation of the first rotating shaft 902, through the meshing of the second gear 905 and the first gear 903, drives the second rotating shaft 904 to rotate in the supporting connection... The internal rotation of the receiving seat 2 drives the rotation of the manifold on the fixed claw plate 906 to rotate for welding via the rotation of the second rotating shaft 904. By manually turning the rotating handle 802, the rotation of the rotating handle 802 drives the threaded rotating rod 801 to rotate inside the welding base 1. The rotation of the threaded rotating rod 801, and the threaded connection between the threaded rotating rod 801 and the sliding threaded block 803, drives the supporting connecting plate 804 to move left and right inside the welding base 1, so that the welding torch 7 can reach the appropriate welding position. By inserting the welding torch 7 into the interior of the second extrusion plate 813 and the first extrusion plate 809, the reset spring 812 pushes the second extrusion plate 813 at the bottom of the limiting ring 811 to fix the welding torch 7 under the limitation of the fixed connecting column 810.

[0026] Through the above steps, the rotation of the handle 802 drives the threaded rotating rod 801 to rotate inside the welding base 1. The rotation of the threaded rotating rod 801, and the threaded connection between the threaded rotating rod 801 and the sliding threaded block 803, drives the support connecting plate 804 to move left and right inside the welding base 1. This solves the problem that during the welding process of the automotive air conditioning condenser manifold welding fixture, due to different welding positions, we need to adjust the position of the welding gun to weld the part. Because the range of motion of the spray gun position of this device is small, it cannot effectively weld large parts during welding adjustment, which has limitations and affects the welding efficiency.
