DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] Referring to Figure 1As shown in the figure, this embodiment discloses a welding fixture for processing metal elbows, which includes a workbench 1, a reinforcement device 4 and an auxiliary device 5. A chuck 2 is fixedly connected to the surface of the workbench 1. Two fixing blocks 3 are arranged on one side surface of the chuck 2. The reinforcement device 4 is installed on the surface of the workbench 1 by means of the auxiliary device 5.

[0029] Referring to Figure 1 and Figure 2 as well as Figure 3 As shown in the figure, this embodiment discloses that the reinforcement device 4 includes a mounting frame 41. The mounting frame 41 is fixedly connected to the surface of the workbench 1 by means of the auxiliary device 5. A rotating plate 42 is rotatably connected to the surface of the mounting frame 41. A screw rod 43 is threadedly connected through the surface of the rotating plate 42. One end of the screw rod 43 is rotatably connected to a reinforcement plate 44. The cross section of the reinforcement plate 44 is arc-shaped. When welding and processing a metal elbow, first, a short pipe is sleeved on the surfaces of the two fixing blocks 3, and then the fixture is started to make the two fixing blocks 3 move away from each other and simultaneously contact and squeeze the inner wall of the short pipe to limit and fix it. Then, the elbow head is sleeved and fixed on the surface of the fixing block 3. Then, the screw rod 43 on the rotating plate 42 is rotated. Through the rotation of the screw rod 43, the reinforcement plate 44 at one end of the screw rod 43 approaches the elbow head until it contacts and squeezes the arc surface of the elbow head. Then, during the welding process, the fixture will rotate, and at the same time, the rotating plate 42 will rotate on the surface of the mounting frame 41. At this time, when using the fixture to limit the position of the metal elbow during welding, the elbow head can be made more stable, not prone to looseness and deviation, thereby making the welding position more neat and efficient, improving the forming quality of the workpiece, and further improving the use effect of the fixture and the welding efficiency of the elbow.

[0030] Referring to Figure 1 and Figure 2 as well as Figure 3 As shown in the figure, this embodiment discloses that a sliding hole 46 is formed on the surface of the rotating plate 42. A limiting rod 45 is slidably connected to the inner wall of the sliding hole 46. The limiting rod 45 is fixedly connected to one side surface of the reinforcement plate 44. Through the sliding arrangement of the limiting rod 45 and the sliding hole 46, when the reinforcement plate 44 contacts and squeezes the elbow head, the position of the reinforcement plate 44 can be better maintained stable, so that the elbow is more stable during welding. A reinforcement pad 48 is fixedly connected to the inner wall of the reinforcement plate 44. The reinforcement pad 48 is a rubber pad. Through the setting of the reinforcement pad 48, the friction force between the reinforcement plate 44 and the elbow head during contact extrusion is increased, so that the position of the elbow head is more stable, and the use effect of the reinforcement device 4 is improved.

[0031] Referring to Figure 1 and Figure 2 as well as Figure 3As shown, in this embodiment, one end of the mounting bracket 41 is fixedly connected to a bearing 49 on the arc surface. The inner ring of the bearing 49 is fixedly connected to the mounting bracket 41, and the outer ring of the bearing 49 is fixedly connected to the rotating plate 42. Through the setting of the bearing 49, the rotation of the rotating plate 42 on the mounting bracket 41 is smoother, thereby better performing real-time limiting on the elbow head, reducing the frictional damage between the rotating plate 42 and the mounting bracket 41. One end of the screw 43 away from the reinforcement plate 44 is fixedly connected to an operation block 47, and the surface of the operation block 47 is provided with a plurality of anti-slip protrusions. Through the setting of the operation block 47, the screw 43 is more convenient to rotate during use, and thus it is more convenient to make the reinforcement plate 44 contact and press the elbow head, making it more convenient to limit and fix it.

[0032] Referring to Figure 1 and Figure 4 As shown, in this embodiment, the auxiliary device 5 includes a mounting frame 51. The mounting frame 51 is fixedly connected to the surface of the workbench 1. The mounting bracket 41 is clamped with the inner wall of the mounting frame 51. One side surface of the mounting bracket 41 is fixedly connected to a fixing frame 52. The inner wall of the fixing frame 52 is fixedly connected to an insertion block 57, and the insertion block 57 is clamped with the surface of the mounting bracket 41. The surface of the mounting frame 51 is penetrated and inserted with a bolt 53. The bolt 53 is threadedly connected through the surface of the fixing frame 52, and the bolt 53 is penetrated and inserted through the surface of the mounting bracket 41. When installing the reinforcement device 4, first, the mounting bracket 41 is clamped in the inner wall of the mounting frame 51 on the surface of the workbench 1, then the fixing frame 52 is clamped on the surface of the mounting bracket 41, and the insertion block 57 on the inner wall of the fixing frame 52 is clamped on the surface of the mounting bracket 41. Then the bolt 53 is inserted through the surfaces of the mounting frame 51 and the mounting bracket 41, and the bolt 53 is threadedly connected to the surface of the fixing frame 52 to make the position of the mounting bracket 41 stable. At this time, the reinforcement device 4 can be used more conveniently, and thus it is more convenient to fix the elbow head, improving the convenience of using the reinforcement device 4 and further improving the use effect of the fixture.

[0033] Referring to Figure 1 and Figure 4 As shown, in this embodiment, a nut 56 is threadedly connected to the arc surface of the bolt 53, and the nut 56 abuts against the surface of the fixing frame 52. Through the setting of the nut 56, the bolt 53 is more stably installed on the fixing frame 52 and is not easily rotated and loosened, thereby ensuring the stable connection of the fixing frame 52 and making the assembly of the reinforcement device 4 more stable. Two sides of the surface of the fixing frame 52 are respectively fixedly connected to clamping blocks 55, and two sides of the surface of the mounting frame 51 are respectively provided with clamping grooves 54. The clamping blocks 55 are clamped with the inner walls of the clamping grooves 54. Through the clamping setting of the clamping blocks 55 and the clamping grooves 54, the connection between the mounting frame 51 and the fixing frame 52 is more stable and firm, thereby making the position of the mounting bracket 41 more stable and firm, improving the use effect of the auxiliary device 5.

[0034] Working principle: When welding a metal elbow pipe, first sleeved a short pipe on the surfaces of the two fixed blocks 3, then start the fixture to move the two fixed blocks 3 away from each other and simultaneously contact and squeeze the inner wall of the short pipe to limit and fix it. Then sleeve and fix the elbow pipe head on the surface of the fixed block 3. Then rotate the operating block 47 fixedly connected to the screw rod 43 to rotate the screw rod 43 on the rotating plate 42. Through the rotation of the screw rod 43, the reinforcement plate 44 at one end of the screw rod 43 approaches the elbow pipe head until it contacts and squeezes the arc surface of the elbow pipe head. Then during the welding process, the fixture will rotate, and at the same time, the rotating plate 42 will rotate on the surface of the mounting frame 41. At this time, when using the fixture to limit the welding of the metal elbow pipe, the elbow pipe head can be made more stable and not easily loosen and shift, thereby making the welding position more neat and efficient, improving the forming quality of the workpiece, further improving the use effect of the fixture, and the welding efficiency of the elbow.

[0035] When installing the reinforcement device 4, first snap the mounting frame 41 into the inner wall of the mounting frame 51 on the surface of the workbench 1, then snap the fixed frame 52 onto the surface of the mounting frame 41, and make the insertion block 57 on the inner wall of the fixed frame 52 snap onto the surface of the mounting frame 41, and make the clamping block 55 on the fixed frame 52 snap into the clamping groove 54 on the surface of the mounting frame 51. Then insert the bolt 53 through the surfaces of the mounting frame 51 and the mounting frame 41 to thread the bolt 53 with the surface of the fixed frame 52, and then thread the nut 56 onto the bolt 53 to stabilize the position of the mounting frame 41. At this time, the reinforcement device 4 can be used more conveniently, and thus it is more convenient to fix the elbow pipe head, improving the convenience of using the reinforcement device 4 and further improving the use effect of the fixture.
