Description
Technical Field
[0001] This utility model relates to the field of pipe splicing technology, and in particular to a pipe splicing device with positioning function. Background Technology
[0002] Pipe splicing devices are specially designed for connecting pipelines, enabling rapid and secure connections while ensuring the sealing and stability of the pipeline system. These devices are widely used in various fields such as water conservancy, petroleum, natural gas, chemical industry, construction, and household appliances. Pipe splicing devices with positioning functions have broad application prospects in engineering construction and pipeline installation. Through special structural design and working principles, they achieve precise positioning and splicing of pipelines, improving construction efficiency and project quality.
[0003] Existing pipe splicing devices with positioning functions mainly include a base and a support frame. The support frame supports the pipe, and the pipe is pushed from two directions to achieve splicing. However, in actual use, it is difficult to adjust the support frame to suit the size of the pipe, and when splicing two pipes with different sizes, it is impossible to ensure that the axes of the two pipes are in the same horizontal position. As a result, there are great limitations to the splicing of pipes, and the practicality is not high.
[0004] Therefore, a pipe splicing device with positioning function is proposed to address the above problems. Utility Model Content
[0005] To address the shortcomings of existing technologies, such as the difficulty in adjusting support frames to accommodate pipe sizes and the inability to ensure that the axes of two pipes are at the same horizontal level when splicing two pipes of different sizes, the proposed solution addresses these limitations and low practicality.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] A pipe splicing device with positioning function includes a base, a positioning structure fixedly installed at the top of the base, and an adjustment structure fixedly installed at the middle of the top of the base. The positioning structure includes a bracket and a toothed disc fixedly connected to the top of the base. The bracket has three sliding grooves extending through the middle of the bracket. Each of the three sliding grooves is slidably connected to a sliding rod. Each of the three sliding rods is fixedly connected to a pressure plate on the side that is close to each other.
[0008] Preferably, the bracket has three through holes on one side, each through hole extending into the interior of three sliding grooves. Limiting rods are fixedly connected to the side of the three sliding rods near the through holes. The outer walls of the three limiting rods are slidably connected to the inner walls of the three through holes. Limiting discs are fixedly connected to the side of the three limiting rods away from the sliding rods.
[0009] Preferably, three oblique holes are provided on one side of the gear disk, the inner walls of the three oblique holes are slidably connected to the outer walls of the three limiting rods, the diameter of the three limiting plates is slightly larger than the width of the three oblique holes, and the three limiting plates are all located on the side of the gear disk away from the bracket.
[0010] Preferably, a dual-axis servo motor is fixedly installed at the center of the top of the base. The output end of the dual-axis servo motor passes through the bottom of the bracket, and a gear is fixedly connected to the output end of the dual-axis servo motor. The outer wall of the gear is meshed with the outer wall of the gear plate.
[0011] Preferably, the adjustment structure includes a housing fixedly connected to the middle of the top of the base, an adjustment ring rotatably connected inside the housing, and two clamping plates slidably connected to the middle of the adjustment ring, with a fixing plate fixedly connected to the side of each clamping plate that is close to each other.
[0012] Preferably, a bidirectional lead screw is rotatably connected to the bottom of the inner wall of the adjusting ring, and a drive motor is fixedly installed at the bottom inside the adjusting ring.

[0013] Preferably, a gear ring is fixedly connected to the middle of the outer wall of the adjusting ring, a dual-axis servo motor II is fixedly installed at the middle of the top of the base, a retainer is fixedly connected to the middle of the top of the base, the outer wall of the output end of the dual-axis servo motor II passes through the retainer, and a gear II is fixedly connected to the output end of the dual-axis servo motor II, with the outer wall of the gear II meshing with the outer wall of the gear ring.
[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0015] 1. This utility model provides a pipe splicing device with positioning function. Through the positioning structure, three sliding rods slide synchronously inside the slide groove, which can cause three pressure plates to slide synchronously towards each other, thereby accurately positioning the pipe. At the same time, the gears on both sides of the base are individually controlled by the output shafts on both sides of the dual-axis servo motor, so that even if there is a slight difference in the diameter of the two pipes to be spliced, the axis of the two pipes can be kept in the same position, which facilitates docking and improves the practicality of the device.
[0016] 2. This utility model provides a pipe splicing device with positioning function. After the pipe is fixed by the fixing plate through the adjustment structure, the dual-axis servo motor drives the gear to rotate, which in turn drives the gear ring to rotate, which in turn drives the adjustment ring to rotate. This allows the angle and position of the pipe to be adjusted, thereby enabling the two pipes to be quickly aligned at the docking position. At the same time, the two pipes rotate synchronously, which facilitates the splicing operation and improves the splicing efficiency. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Specific implementation examples are given below.
[0024] Please see Figure 1 - Figure 4This utility model provides a technical solution: a pipe splicing device with positioning function, including a base 1, a positioning structure 2 fixedly installed at the top of the base 1, and an adjustment structure 3 fixedly installed at the middle of the top of the base 1. The positioning structure 2 includes a bracket 21 and a gear plate 26 fixedly connected to the top of the base 1. The bracket 21 has three sliding grooves 22 extending through the middle of the bracket 21. Each of the three sliding grooves 22 is slidably connected to a sliding rod 23. Each of the three sliding rods 23 is fixedly connected to a pressure plate 24 on the side of each sliding rod that is close to each other. The three sliding rods 23 slide synchronously in the sliding grooves 22, thereby causing the three pressure plates 24 to slide synchronously towards each other, thereby enabling precise positioning of the pipe. At the same time, the gears 28 on both sides of the base 1 are individually controlled by the output shafts on both sides of the dual-axis servo motor 29, so that even if there is a slight difference in the diameter of the two pipes to be spliced, the axis of the two pipes can be kept in the same position, thus facilitating docking.
[0025] like Figure 2 As shown, the bracket 21 has three through holes 221 on one side, which extend into the interior of the three sliding grooves 22. The three sliding rods 23 are fixedly connected to the side of the through holes 221 with limit rods 25. The outer walls of the three limit rods 25 are slidably connected to the inner walls of the three through holes 221. The side of the three limit rods 25 away from the sliding rods 23 is fixedly connected to a limit plate. The limit plate can limit the toothed disc 26 to prevent it from falling off.
[0026] like Figure 2 As shown, three oblique holes 27 are provided on one side of the gear disk 26, and the inner walls of the three oblique holes 27 are slidably connected to the outer walls of the three limiting rods 25 respectively. The diameter of the three limiting disks is slightly larger than the width of the three oblique holes 27, and the three limiting disks are all located on the side of the gear disk 26 away from the bracket 21. When the gear disk 26 rotates, the oblique holes 27 press against the limiting rods 25. At this time, the oblique rods and the sliding rods 23 are simultaneously limited by the sliding grooves 22, which causes the three sliding rods 23 to slide synchronously inside the sliding grooves 22.
[0027] like Figure 1 and Figure 2 As shown, a dual-axis servo motor 29 is fixedly installed at the center of the top of the base 1. The output end of the dual-axis servo motor 29 passes through the bottom of the bracket 21, and a gear 28 is fixedly connected to the output end of the dual-axis servo motor 29. The outer wall of the gear 28 meshes with the outer wall of the gear disk 26. The rotation of the dual-axis servo motor 29 drives the gear 28 to rotate, which in turn drives the gear disk 26 to rotate. At the same time, the gears 28 on both sides of the base 1 are individually controlled by the output shafts on both sides of the dual-axis servo motor 29. This ensures that even if there is a slight difference in the diameter of the two pipes to be spliced, the axis of the two pipes can be kept in the same position, which facilitates docking.
[0028] like Figure 3 and Figure 4 As shown, the adjustment structure 3 includes a housing 31 fixedly connected to the middle of the top of the base 1. An adjustment ring 32 is rotatably connected inside the housing 31. Two clamping plates 35 are slidably connected to the middle of the adjustment ring 32. A fixing plate 36 is fixedly connected to the side of the two clamping plates 35 that are close to each other. The two clamping plates 35 slide towards each other, thereby driving the two fixing plates 36 to fix the pipe, thus ensuring the stability of the pipe during the splicing process. At the same time, it is convenient to adjust the angle of the pipe.
[0029] like Figure 4 As shown, a bidirectional lead screw 34 is rotatably connected to the bottom of the inner wall of the adjusting ring 32. A drive motor 33 is fixedly installed inside the bottom of the adjusting ring 32. The output end of the drive motor 33 is fixedly connected to one end of the bidirectional lead screw 34. The bottoms of the two clamping plates 35 are connected to the outer wall of the bidirectional lead screw 34, and the two clamping plates 35 are symmetrically distributed relative to the bidirectional lead screw 34. The drive motor 33 drives the bidirectional lead screw 34 to rotate, thereby causing the two clamping plates 35 to slide towards each other. The thread action between the bidirectional lead screw 34 and the clamping plates 35 can fix the clamping plates 35, thereby ensuring the fixing effect of the fixing plate 36 on the pipeline.
[0030] like Figure 3 As shown, a gear ring 321 is fixedly connected to the middle of the outer wall of the adjusting ring 32. A dual-axis servo motor 37 is fixedly installed at the middle of the top of the base 1. A retainer 38 is fixedly connected to the middle of the top of the base 1. The outer wall of the output end of the dual-axis servo motor 37 passes through the retainer 38, and a gear 39 is fixedly connected to the output end of the dual-axis servo motor 37. The outer wall of the gear 39 meshes with the outer wall of the gear ring 321. The dual-axis servo motor 37 drives the gear 39 to rotate, which in turn drives the gear ring 321 to rotate, which in turn drives the adjusting ring 32 to rotate. This allows for adjustment of the angle position of the pipe, enabling rapid alignment of the two pipes. Simultaneous synchronous rotation of the two pipes facilitates splicing operations and improves splicing efficiency.
[0031] The working principle of this utility model is as follows: In use, two pipes to be spliced are passed through the supports 21 on both sides, and then the dual-axis servo motor 29 is driven to rotate, which in turn drives the gear 28 to rotate, which in turn drives the gear plate 26 to rotate. When the gear plate 26 rotates, the inclined hole 27 presses against the limiting rod 25. At this time, the inclined rod and the sliding rod 23 are simultaneously limited by the sliding groove 22, which causes the three sliding rods 23 to slide synchronously inside the sliding groove 22, thereby causing the three pressure plates 24 to slide synchronously towards each other, thus positioning the pipes. At the same time, the gears 28 on both sides of the base 1 are individually controlled by the output shafts on both sides of the dual-axis servo motor 29, so that even if there is a slight difference in the diameter of the two pipes to be spliced, the axis of the two pipes can be guaranteed. With the two pipes aligned, they are easier to connect. Once the pipes are in contact, their ends are located inside the two adjusting rings 32. At this point, the drive motor 33 is activated, which in turn drives the bidirectional lead screw 34 to rotate. This causes the two clamping plates 35 to slide towards each other, which in turn drives the two fixing plates 36 to fix the pipes, thus ensuring the stability of the pipes during the splicing process. Simultaneously, the dual-axis servo motor 37 is driven to rotate, which in turn drives the gear 39 to rotate, which in turn drives the gear ring 321 to rotate, which in turn drives the adjusting ring 32 to rotate. This allows for adjustment of the pipe's angle and position, enabling the two pipes to be quickly aligned. The synchronous rotation of the two pipes facilitates the splicing operation and improves splicing efficiency.
