Description

Technical Field

[0001] This utility model relates to the field of MPP power pipe welding technology, and in particular to an automatic welding device for MPP power pipes. Background Technology

[0002] MPP power pipes (modified polypropylene power pipes) are widely used in power cable protection projects due to their excellent electrical insulation, high temperature resistance, and pressure resistance. In actual construction, it is often necessary to perform welding operations on MPP power pipes using a hot melt gun to facilitate cable threading or branch connections. Traditional welding methods mainly rely on manual operation. When manually aligning the welding hole position, deviations are easily caused, requiring repeated adjustments to the pipe position to align the welding hole point. This operation is cumbersome, time-consuming, and can easily lead to inaccurate welding hole positions, affecting subsequent cable installation. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide an automatic welding device for MPP power pipes.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses an automatic welding device for MPP power pipes, comprising a support base. Two horizontal grooves are provided on the top of the support base, and two symmetrically distributed clamping mechanisms are installed on the top of the support base. Each clamping mechanism includes a first electric push rod, a baffle, and a slider. A baffle is fixedly connected to the telescopic end of the first electric push rod, and two sliders are fixedly connected to the bottom of the baffle. A fastening frame is fixedly connected to the baffle, and a limiting frame is slidably fitted onto the outside of the fastening frame. A bolt is threaded to the top of the limiting frame, and a clamping plate is fixedly connected to the limiting frame. A first bracket and a second bracket are fixedly connected to the top of the support base, and a horizontal plate is fixed between the first and second brackets. A second electric push rod is fixedly connected to the bottom center of the horizontal plate, and a carrying plate is fixedly connected to the telescopic end of the second electric push rod. A hot melt gun is fixedly connected to the bottom center of the carrying plate, and two guide rods are fixedly connected to the top of the carrying plate. A positioning mechanism is installed on the carrying plate.

[0006] In a preferred embodiment of this invention, the guide rod passes through the horizontal plate, and the guide rod and the horizontal plate are slidably connected.

[0007] As a preferred technical solution of this utility model, the fastening frame has a "U" shaped structure, and the fixed end of the first electric push rod is fixed to the first bracket.

[0008] As a preferred technical solution of this utility model, the slider and the groove are adapted to each other, and the slider is slidably connected inside the groove.

[0009] As a preferred technical solution of this utility model, the positioning mechanism includes a mounting plate, a servo motor and a transmission shaft. The servo motor is fixedly connected to the mounting plate, and the transmission shaft runs through the inside of the mounting plate. An adjustment frame is fixedly sleeved on the outside of the transmission shaft. The drive end of the servo motor runs through the mounting plate and is fixedly connected to a first gear. A second gear meshes with the first gear. A laser head is fixedly connected to the bottom of the adjustment frame.

[0010] As a preferred technical solution of this utility model, the mounting plate is fixedly connected to the bottom of the carrier plate, the second gear is fixedly sleeved on the outside of the transmission shaft, the first gear and the second gear have the same number of teeth, the center point of the hot melt gun and the center point of the laser head are on the same vertical line, and the mounting plate and the transmission shaft are rotatably connected by bearings.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. The positions of the holes to be melted are marked on the pipe in advance. The positioning mechanism uses a vertically downward laser beam. When the laser point falls on the marked point on the pipe, it is the area of ​​the hole to be melted. This method can quickly align the hot melt gun with the area of ​​the hole to be melted on the pipe, improving the melting accuracy and reducing the melting error. The alignment of the hole can be completed without repeatedly moving the pipe. The positioning mechanism has a high degree of automation, which reduces the positioning time during melting and improves the melting efficiency. When the actual melting is required, the servo motor can drive the first gear and the second gear to mesh, thereby driving the adjustment frame and the laser head to rotate at a certain angle, ensuring that the hot melt gun is aligned with the actual melting hole of the pipe.

[0013] 2. The two sets of clamping mechanisms can adjust the position of the clamping plates, making it convenient to clamp the pipe according to its actual length. This facilitates subsequent welding of the pipe. Moreover, the relative movement of the two sets of clamping mechanisms can clamp both ends of the pipe, resulting in higher clamping efficiency.

[0019] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0020] In the attached diagram, all identical reference numerals refer to the same components.

[0021] like Figure 1-3 As shown, this utility model provides an automatic welding device for MPP power pipes, including a support base 1. Two horizontally oriented grooves 11 are provided on the top of the support base 1, and two symmetrically distributed clamping mechanisms 2 are installed on the top of the support base 1. Each clamping mechanism 2 includes a first electric push rod 21, a baffle 22, and sliders 23. The baffle 22 is fixedly connected to the telescopic end of the first electric push rod 21. Two sliders 23 are fixedly connected to the bottom of the baffle 22, and a fastening frame 24 is fixedly connected to the baffle 22. A limiting frame 25 is slidably sleeved on the outside of the fastening frame 24. Bolt 26 is threaded at the top of 5, and clamping plate 27 is fixed on the limiting frame 25. The fastening frame 24 has a "U" shaped structure. The fixed end of the first electric push rod 21 is fixed on the first bracket 3. The slider 23 and the slide groove 11 are compatible. The slider 23 is slidably connected inside the slide groove 11. The two sets of clamping mechanisms 2 can adjust the position of the clamping plate 27 to make it easy to clamp the pipe according to the actual length of the pipe. It is easy to perform subsequent welding on the pipe. Moreover, the relative movement of the two sets of clamping mechanisms 2 can clamp the front and rear ends of the pipe, which is more efficient.

[0022] A first bracket 3 and a second bracket 4 are fixedly connected to the top of the support base 1. A horizontal plate 5 is fixedly connected between the first bracket 3 and the second bracket 4. A second electric push rod 6 is fixedly connected to the bottom center of the horizontal plate 5. A carrying plate 7 is fixedly connected to the telescopic end of the second electric push rod 6. A hot melt gun 71 is fixedly connected to the bottom center of the carrying plate 7. Two guide rods 8 are fixedly connected to the top of the carrying plate 7. The guide rods 8 pass through the horizontal plate 5 and are slidably connected to the horizontal plate 5. A positioning mechanism 9 is installed on the carrying plate 7. The positioning mechanism 9 includes a mounting plate 91, a servo motor 92, and a transmission shaft 93. The servo motor 92 is fixedly connected to the mounting plate 91, and the transmission shaft 93 passes through the interior of the mounting plate 91. An adjusting frame 94 is fixedly sleeved on the exterior of the transmission shaft 93. The drive end of the servo motor 92 passes through the mounting plate 91 and is fixedly connected to a first gear 95. A second gear 96 meshes with the first gear 95. A laser head 97 is fixedly connected to the bottom of the adjusting frame 94. The mounting plate 91 is fixedly connected to the bottom of the carrying plate 7. Wheel 96 is fixedly sleeved on the outside of transmission shaft 93. The first gear 95 and the second gear 96 have the same number of teeth. The center point of the hot melt gun 71 and the center point of the laser head 97 are on the same vertical line. The mounting plate 91 and the transmission shaft 93 are rotatably connected by bearings. The position of the hole to be melted is marked on the pipe in advance. The positioning mechanism 9 emits a laser beam vertically downward. When the laser point falls on the marked point on the pipe, it is the area of ​​the hole to be melted. This method can quickly align the hot melt gun 71 with the area of ​​the hole to be melted on the pipe, improve the melting accuracy, reduce the melting error, and complete the melting alignment without repeatedly moving the pipe. The positioning mechanism 9 has a high degree of automation, reduces the positioning time during melting, and improves the melting efficiency. When actual melting is required, the servo motor 92 can drive the first gear 95 and the second gear 96 to mesh, thereby driving the adjusting frame 94 and the laser head 97 to rotate at a certain angle, ensuring that the hot melt gun 71 is actually melting the pipe.

[0023] Among them, the model of servo motor 92 is ACSM110-G04030LZ.

[0024] Working principle: When using this device, first adjust the positions of the four limit frames 25, thereby changing the positions of the four clamping plates 27. After the positions of the clamping plates 27 are adjusted, tighten the four bolts 26. At this time, the clamping plates 27 can be fixed on the fastening frame 24. Next, mark the area to be melted on the pipe. Then, place the pipe on the support base 1 and turn on the laser head 97. Since the laser head 97 is vertically distributed, the laser beam emitted by the laser head 97 falls on the pipe to form a laser point. At this time, the center point of the hot melt gun 71 is on the same vertical line as the area to be melted, completing the precise positioning. After positioning, control the two first electric push rods 21 to extend. At this time, the two baffles 22 can be moved relative to each other, thereby bringing the hot melt gun 71 into place. Two of the clamping plates 27 and the other two clamping plates 27 are moved relative to each other to ensure that the clamping plates 27 are in close contact with the pipe and to achieve a stable clamping of the pipe. Then, the servo motor 92 is controlled to reverse, which can drive the first gear 95 to reverse, and then drive the second gear 96 meshing with the first gear 95 to rotate forward, thereby driving the transmission shaft 93, the adjusting frame 94 and the laser head 97 to rotate forward, so that the adjusting frame 94 can be moved to the front of the hot melt gun 71. Then, the second electric push rod 6 is controlled to extend, and the second electric push rod 6 pushes the carrier plate 7 to move downward along the guide rod 8. The hot melt gun 71 contacts the surface of the pipe to melt the hole. After the melting hole is completed, the second electric push rod 6 is reset, the clamping mechanism 2 releases the pipe, and the processed pipe can be taken out.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
