DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 2 As shown, an aluminum tube welding positioning device includes a first electric cylinder 1. The first electric cylinder 1 is a prior art and will not be described in detail. The setting of the first electric cylinder 1 can effectively promote the movement of subsequent components. The other end of the first electric cylinder 1 is fixedly connected to one side of the second limiting vertical plate 14. The setting of the second limiting vertical plate 14 can effectively ensure that the first electric cylinder 1 always remains stable during the movement.

[0025] like Figure 1 and Figure 2 As shown, the bottom of the second limiting vertical plate 14 is fixedly connected to the top of the first base disc 5, there are two groups of first base discs 5, and a reinforcing guide single rod 19 is fixedly connected between the two groups of first base discs 5. There are two groups of reinforcing guide single rods 19, and the outer circumferential surfaces of the two groups of first base discs 5 are respectively fixedly connected with triangular support frames 15. The purpose of setting multiple groups of first base discs 5 is to position the two groups of pipe fittings, thereby ensuring that the joints of the pipe fittings remain neat.

[0026] like Figure 1 and Figure 2 As shown, the outer circumferential surface of the first base disc 5 is fixedly connected with a triangular support frame 15. The setting of the triangular support frame 15 can effectively ensure that the first base disc 5 remains stable. The bottom of the triangular support frame 15 is fixedly connected to the top of the first workbench 16. The bottom of the first workbench 16 is fixedly connected to the top of the first balancing base 17. There are four groups of first balancing bases 17. The four groups of first balancing bases 17 are evenly distributed at the bottom of the first workbench 16. The purpose of setting multiple groups of first balancing bases 17 is to effectively ensure the stability of the positioning device during operation and not prone to tilting.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, the top of the first workbench 16 is fixedly connected to the bottom of the waste collection box 18. The setting of the waste collection box 18 saves the time of subsequent staff in cleaning up the waste. One end of the first electric cylinder 1 is rotatably connected to the middle part of the U-shaped limit block 2. The bottom of the U-shaped limit block 2 is fixedly connected to the top of the first sliding plate 3. The top of the first sliding plate 3 is fixedly connected to the bottom of the first limit vertical plate 8. There are two groups of first limit vertical plates 8. A second guide single plate 9 is fixedly connected between the two groups of first limit vertical plates 8. The purpose of setting multiple groups of first limit vertical plates 8 is to effectively ensure the stability of other components.

[0028] like Figure 2and Figure 4 As shown, the top of the second guide plate 9 is slidably connected to the groove at the bottom of the U-shaped positioning module 10. The setting of the second guide plate 9 can effectively ensure that the U-shaped positioning module 10 remains stable at all times during the movement. The bottom of the U-shaped positioning module 10 is rotatably connected to the second positioning roller 11. There are two groups of second positioning rollers 11. The middle part of the U-shaped positioning module 10 is provided with a control guide groove 12. The purpose of setting multiple groups of second positioning rollers 11 is to effectively push the pipe to move and clamp the pipe, thereby ensuring that the pipe always remains stationary.

[0029] like Figure 2 As shown, the bottom of the second guide single plate 9 is fixedly connected to the top of the first sliding plate 3, and the middle of the first limiting vertical plate 8 is fixedly connected with a guide control single rod 13. There are two groups of guide control single rods 13. The guide control single rods 13 are existing technologies and will not be described in detail. The guide control single rods 13 themselves are elastic to avoid collisions between components.

[0030] like Figure 2 As shown, the groove at the bottom of the first sliding plate 3 is slidably connected to the top of the first guide single plate 4, the bottom of the first guide single plate 4 is fixedly connected to one side of the first base disc 5, one side of the first base disc 5 is fixedly connected to one side of the L-shaped limit module 6, and the middle part of the L-shaped limit module 6 is rotatably connected to the first positioning roller 7. The mutual cooperation between the L-shaped limit module 6 and the first positioning roller 7 can effectively ensure the stability of the pipe fitting.

[0031] It should be noted that in actual use of the device, the pipe fitting is first placed in the groove in the first base disc 5, and the first electric cylinder 1 is started to work, so as to push the first sliding plate 3 under the U-shaped limit block 2 to slide on the first guide single plate 4, thereby driving the second guide single plate 9 on the first limit vertical plate 8 to move synchronously, so that the second positioning roller 11 under the U-shaped positioning module 10 moves, so that the second positioning roller 11 gradually clamps the pipe fitting, and the mutual cooperation between the first positioning roller 7 and the second positioning roller 11 at the bottom can effectively position the pipe fitting, and when the second positioning roller 11 positions the pipe fitting and thus encounters resistance, the U-shaped positioning module 10 can slide horizontally on the second guide single plate 9, so that the U-shaped positioning module 10 touches the guide control single rod 13, and under the action of the elasticity of the guide control single rod 13 itself, the U-shaped positioning module 10 is gradually reset, thereby driving the pipe fitting to reset, so that the joints of the pipe fittings can be kept neat, which greatly improves the welding efficiency and welding quality of the staff.
