Description

Technical Field

[0001] This utility model relates to the field of brazing fixture technology, and in particular to a brazing oxygen lance nozzle fixture. Background Technology

[0002] Brazing is a welding method in which a filler metal with a flux that is below the melting point of the workpiece and the workpiece are heated to the melting temperature of the filler metal, and the liquid filler metal is used to fill the gaps in the solid workpiece to connect the metals.

[0003] There are many commonly used brazing processes, mainly distinguished by the equipment used and their working principles. For example, based on the heat source, there are infrared, electron beam, laser, plasma, and glow discharge brazing; based on the working process, there are contact reaction brazing and diffusion brazing. Contact reaction brazing utilizes the reaction between the filler metal and the base metal to generate a liquid phase that fills the joint gap. Diffusion brazing increases the holding and diffusion time, allowing the weld to become fully homogenized with the base metal, thus obtaining a joint with properties identical to the base metal. Almost all heating sources can be used as brazing heat sources.

[0004] In the existing technology, the existing brazing oxygen lance nozzle fixture may lack flexible angle adjustment function, making it difficult to operate in some complex welding positions; in traditional brazing operations, operators usually need to hold the welding torch to weld the workpiece, but it is difficult to ensure the relative positional accuracy between the torch and the workpiece when welding by hand, resulting in unstable brazing quality and easy deviation. Utility Model Content

[0015] The clamping assembly is movably mounted on the third sliding structure and is used to clamp the brazing oxygen lance nozzle.

[0016] Furthermore, the base includes a support member, a support plate disposed on the top of the support member, and a rotating member rotatably disposed on the top center of the support plate. A bearing hole is provided in the center of the support plate, and a rotating bearing is disposed in the bearing hole. The rotating member is fixedly connected to the rotating bearing, and the rotating bearing is smoothly connected to the inner wall of the bearing hole.

[0017] Furthermore, the support structure includes a T-shaped bracket threaded to the top of the rotating component, and reinforcing members for strengthening the T-shaped bracket are provided on both sides of the T-shaped bracket.

[0018] Furthermore, a water injection hole and a drain hole are provided on one side of the support plate, and the water injection hole and the drain hole are connected through a water cooling channel inside the support plate.

[0019] Furthermore, the X-axis adjustment assembly also includes a first drive motor disposed at the end of the first slide rail away from the support structure, the first drive motor being used to drive the first sliding structure.

[0023] The beneficial effects of this utility model are as follows: By rotating the support structure on the base, the brazing oxygen lance nozzle is directed toward the workpiece to be brazed. By sliding the first sliding structure on the first slide rail, the second sliding structure is simultaneously driven to slide on the second slide rail, allowing the brazing oxygen lance nozzle to move to the top of the workpiece to be welded. By sliding the third sliding structure on the third slide rail, the distance between the brazing oxygen lance nozzle and the workpiece to be welded can be adjusted. This allows the support structure, the X-axis adjustment component, and the Y-axis adjustment component to meet the requirements of brazing at complex angles, achieving flexible angle adjustment. At the same time, by clamping the brazing oxygen lance nozzle with the clamping component, the relative positional accuracy between the brazing oxygen lance nozzle and the workpiece can be ensured, increasing the brazing quality and avoiding deviations.

[0034] Support structure 20;

[0035] The support structure 20 is rotatably mounted on the base 10;

[0036] Specifically, the support structure 20 is rotatably mounted on the support plate 12 via the rotating member 13.

[0037] Furthermore, the support structure 20 includes a T-shaped bracket 21 threadedly connected to the top of the rotating member 13, and reinforcing members 22 for reinforcing the T-shaped bracket 21 are provided on both sides of the T-shaped bracket 21.

[0038] X-axis adjustment assembly 30;

[0039] The X-axis adjustment assembly 30 includes a first connecting plate 31 connected to the end of the support structure 20 away from the base 10, a first slide rail 32 arranged along the length direction of the first connecting plate 31, a first sliding structure 33 slidably arranged on the first slide rail 32, a second slide rail 34 arranged along the length direction of the first connecting plate 31 and parallel and spaced apart from the first slide rail 32, and a second sliding structure 35 slidably arranged on the second slide rail 34.

[0040] Specifically, the first connecting plate 31 is disposed at the end of the T-shaped bracket 21 away from the rotating member 13.

[0041] Furthermore, the X-axis adjustment assembly 30 also includes a first drive motor 36 disposed at the end of the first slide rail 32 away from the support structure 20, the first drive motor 36 being used to drive the first sliding structure 33.

[0042] Y-axis adjustment component 40;

[0043] The Y-axis adjustment assembly 40 includes a second connecting plate 41 connected to the first sliding structure 33 and the second sliding structure 35, a third slide rail 42 arranged along the length direction of the second connecting plate 41, and a third sliding structure 43 slidably arranged on the third slide rail 42.

[0044] Furthermore, the Y-axis adjustment assembly 40 also includes a second drive motor 44 disposed at the end of the third slide rail 42 away from the base 10, the second drive motor 44 being used to drive the third sliding structure 43.

[0045] Clamping component 60;

[0046] The clamping assembly 60 is movably disposed on the third sliding structure 43, and the clamping assembly 60 is used to clamp the brazing oxygen lance nozzle 62.

[0047] Understandably, by rotating the rotating component 13 on the support plate, the orientation of the brazing oxygen torch nozzle 62 can be adjusted to align with the workpiece to be welded; the first drive motor 36 drives the first sliding structure 33 to slide on the first slide rail 32, thereby causing the second connecting plate 41 to slide on the first sliding structure 33 and the second sliding structure 35, thus the first drive motor 36 can move the brazing oxygen torch nozzle 62 to the top of the workpiece to be welded; the second drive motor 44 drives the third sliding structure 43 to slide on the third slide rail, thus the second drive motor 44 can adjust the distance between the brazing oxygen torch nozzle 62 and the workpiece to be welded, thereby enabling the cooperation between the base 10, the support structure 20, the X-axis adjustment component 30, and the Y-axis adjustment component 40 to meet the requirements of complex angle brazing and achieve flexible angle adjustment function.

[0048] Furthermore, an angle adjustment component 50 is provided between the clamping component 60 and the Y-axis adjustment component 40. The angle adjustment component 50 includes a fixing member 51 connected to the third sliding structure 43 and a third drive motor 52 disposed on the fixing member 51 facing the base 10. The output end of the third drive motor 52 passes through the fixing member 51 and extends towards the base 10.

[0049] Furthermore, the clamping assembly 60 includes a clamping member 61 detachably disposed on the output end of the third drive motor 52 and a brazing oxygen lance nozzle 62 detachably disposed on the side of the clamping member 61 away from the output end of the third drive motor 52.

[0050] Understandably, by clamping the brazing oxygen lance nozzle 62 with the clamping member 61, the relative positional accuracy between the brazing oxygen lance nozzle 62 and the workpiece can be ensured, increasing the brazing quality and avoiding deviations. By driving the third drive motor 52, the clamping member 61 rotates around the output end of the third drive motor 52 as the center, thereby causing the brazing oxygen lance nozzle 62 to rotate around the output end of the third drive motor 52 with the distance between the output end of the third drive motor 52 and the brazing oxygen lance nozzle 62 as the radius, thus enabling the present invention to complete circular arc welding. Furthermore, the clamping member 61 is detachable, allowing for the adaptation to circular arc welding of different radii by replacing clamping members 61 of different lengths. At the same time, the detachable brazing oxygen lance nozzle 62 allows the operator to use different brazing oxygen lance nozzles 62 according to different situations.

[0051] Furthermore, a water injection hole 16 and a drain hole 17 are provided on one side of the support plate 12, and the water injection hole 16 and the drain hole 17 are connected through a water cooling channel inside the support plate 12.

[0052] Understandably, by continuously injecting coolant into the water inlet 16 and injecting coolant discharged from the drain hole 17 into the water inlet 16, the coolant circulates within the water cooling channel, absorbing heat and improving heat dissipation.

[0053] In summary, the brazing oxygen lance nozzle fixture in the above embodiments of this utility model, by rotating the support structure on the base, allows the brazing oxygen lance nozzle to face the workpiece to be brazed. By sliding the first sliding structure on the first slide rail, simultaneously driving the second sliding structure to slide on the second slide rail, the brazing oxygen lance nozzle can be moved to the top of the workpiece to be welded. By sliding the third sliding structure on the third slide rail, the distance between the brazing oxygen lance nozzle and the workpiece to be welded can be adjusted. This allows the support structure, the X-axis adjustment component, and the Y-axis adjustment component to meet the requirements of brazing at complex angles, achieving flexible angle adjustment. Simultaneously, by clamping the brazing oxygen lance nozzle with the clamping component, the relative positional accuracy between the brazing oxygen lance nozzle and the workpiece can be ensured, increasing brazing quality and preventing deviations.
