Description

Technical Field

[0001] This application relates to the technical field of welding support devices, and particularly to a pipe fitting welding support and positioning device. Background Technique

[0002] Pipe fitting welding is a method of connecting pipe fittings into a complete structure through welding technology. Before welding the pipe fittings, it is necessary to support and position the welded pipe fittings to maintain the stability of welding. The existing support and positioning device is composed of a support base and a positioning mechanism arranged at the upper end of the support base. When welding, the two pipes are spliced together, then positioned, and then welded.

[0003] The existing welding support and positioning device still has certain drawbacks during welding. Since the pipe fittings may be circular or rectangular, they are clamped and positioned in a unified manner during welding. Different pipe fittings are positioned by the same positioning mechanism, which is likely to damage the pipe fittings during welding positioning (due to different stress methods). And the existing positioning device is not convenient to change the positioning angle and cannot be flexibly used according to the welding requirements. Therefore, this application proposes a pipe fitting welding support and positioning device. Utility Model Content

[0034] Embodiment

[0035] As Figures 1-4 shown, a pipe fitting welding support and positioning device proposed in the present application includes a support base 1 and a first support plate 2 fixedly connected to the upper end thereof. Support legs are fixedly connected to the four corners of the bottom end of the support base 1, and an anti-slip pad is fixedly connected to the bottom end of each support leg. One end of the first support plate 2 is rotatably connected to a second support plate 3, and positioning mechanisms 4 for positioning welding parts are provided on one side of the first support plate 2 and the second support plate 3; the two positioning mechanisms 4 do not interfere with each other during use.

[0036] Furthermore, an angle adjustment mechanism 5 for controlling the angles of the first support plate 2 and the second support plate 3 is provided on the side surface of the support base 1. During welding, the support and positioning angles of the first support plate 2 and the second support plate 3 can be adjusted according to the welding angle of the two pipe fittings, making the device more flexible to use.

[0037] Specifically, a first directional support groove 21 and a first variable-direction support groove 22 are formed on the upper surface of the first support plate 2, and a second directional support groove 31 and a second variable-direction support groove 32 are formed on the side surface of the second support plate 3. The second directional support groove 31 and the second variable-direction support groove 32 correspond to the first directional support groove 21 and the first variable-direction support groove 22 respectively. The width of the second variable-direction support groove 32 is the same as that of the first variable-direction support groove 22, and the positioning arcs of the second directional support groove 31 and the first directional support groove 21 also match.

[0038] Among them, the first directional support groove 21 and the second directional support groove 31 are both arc-shaped, and the first variable-direction support groove 22 and the second variable-direction support groove 32 are both rectangular. A support block 33 is fixedly connected to the side of the second support plate 3 away from the second directional support groove 31 and the second variable-direction support groove 32. The outer end surface of the support block 33 is arc-shaped. When the second support plate 3 is horizontal with the first support plate 2, the outer arc surface of the support block 33 contacts the support base 1 for supporting the second support plate 3.

[0039] Specifically, the positioning mechanism 4 includes a cylinder 41 installed on the outer surface of the first support plate 2 or the second support plate 3. A control plate 42 is fixedly connected to the telescopic end of the cylinder 41. Both ends of the control plate 42 are connected with connecting plates 43. One end of one connecting plate 43 is fixedly connected with an arc-shaped positioning block 44, and the end of the other connecting plate 43 is fixedly connected with a rectangular positioning block 45. The arc-shaped positioning block 44 corresponds to the arc-shaped groove, and the rectangular positioning block 45 corresponds to the rectangular groove.

[0040] Further, the angle adjustment mechanism 5 includes a pair of rotating shafts 51 for connecting the first support plate 2 and the second support plate 3. The second support plate 3 is fixedly connected to the rotating shafts 51, and the rotating shafts 51 are rotatably connected to the first support plate 2. Driven gears 52 are fixedly sleeved on the outer ends of the two rotating shafts 51. A transmission shaft 53 is rotatably connected through the side surface of the support base 1. Driving gears 54 are fixedly sleeved on both ends of the transmission shaft 53. The two driving gears 54 are respectively meshed with the two driven gears 52 for transmission. A motor base 6 is fixedly connected to the side surface of the support base 1. A servo motor 7 is installed at the outer end of the motor base 6. The output shaft of the servo motor 7 is fixedly connected to one end of the transmission shaft 53. By controlling the rotation state of the transmission shaft 53 through the servo motor 7, the support angle between the second support plate 3 and the first support plate 2 is controlled.

[0041] The working principle of this embodiment is as follows: This device can support and fix circular pipe fittings or rectangular pipe fittings. When the pipe fittings to be welded are circular pipe fittings, the two pipe fittings to be welded are respectively placed in the first directional support groove 21 and the second directional support groove 31; when the pipe fittings to be welded are rectangular pipe fittings, the two pipe fittings to be welded are respectively placed in the first variable-direction support groove 22 and the second variable-direction support groove 32; then, adjust the angles of the first support plate 2 and the second support plate 3 according to the welding angle requirements. The specific adjustment method is to start the servo motor 7. The output shaft of the servo motor 7 rotates to drive the transmission shaft 53 to rotate. The rotation of the transmission shaft 53 causes the two sets of driving gears 54 to mesh and drive with the two sets of driven gears 52 respectively, thereby driving the two rotating shafts 51 to rotate, and finally changing the angle of the second support plate 3. When adjusted to the appropriate angle, the close ends of the two pipe fittings placed on the upper ends of the first support plate 2 and the second support plate 3 are in contact. Next, start the two cylinders 41. The telescopic ends of the two cylinders 41 retract, driving the two control plates 42 to move closer to the first support plate 2 and the second support plate 3 respectively. Further, the two sets of arc-shaped positioning blocks 44 and the rectangular positioning blocks 45 move closer to the first support plate 2 and the second support plate 3 respectively to fix the pipe fittings on the first support plate 2 and the second support plate 3, and then welding operations are carried out. By opening the first directional support groove 21 and the first variable-direction support groove 22 on the side of the first support plate 2, and opening the second directional support groove 31 and the second variable-direction support groove 32 on the side of the second support plate 3, and with the cooperation of the two positioning mechanisms 4, the fixing of pipe fittings of different shapes is completed. The targeted positioning can avoid excessive extrusion of the pipe fittings during welding positioning and damage to the pipe fittings. By rotatably connecting the second support plate 3 to one end of the first support plate 2 and arranging an angle adjustment mechanism 5 on the side of the support base 1, the support angle of the second support plate 3 is adjusted through the angle adjustment mechanism 5, so that welding at different angles can be completed, and the operation is convenient and practical.

[0042] The above specific embodiments are only the preferred embodiments of the present application. Based on the technical solutions of the present application and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments; the above specific embodiments are only explanations of the present application and do not limit the present application.
