Description

Technical Field

[0001] This utility model relates to the field of composite pipe drilling and positioning technology, and in particular to an easily adjustable positioning device for drilling holes in rust-proof steel-aluminum composite pipes. Background Technology

[0002] Rust-resistant steel-aluminum composite pipe, as a high-performance pipe material, has broad application prospects in many industries. Its unique corrosion resistance, thermal conductivity, and excellent mechanical strength enable the composite pipe to exhibit outstanding performance in fields such as conveying systems and heat exchange systems. With the continuous advancement of technology and the continuous optimization of processes, the application fields of rust-resistant steel-aluminum composite pipe will become even wider. When drilling holes in steel-aluminum composite pipe, precise positioning and efficient operation have always been the focus of technological development.

[0003] In the current market, when processing circular pipes, it is sometimes necessary to drill holes. However, due to the relatively smooth outer surface of the pipe and its circular structure, it is not convenient to drill holes. This can easily lead to misalignment, affecting the processing speed and efficiency, and can also damage the pipe, increasing the difficulty of the work and, to some extent, the cost.

[0004] An existing patent (publication number: CN213944969U) discloses a circular annular pipe positioning and drilling fixture, comprising a fixed bracket, a protective sleeve fixedly installed on the outer side of the fixed bracket, a positioning hole pre-drilled inside the protective sleeve, an installation joint fixedly installed at one end of the fixed bracket, a connecting rod movably installed on the installation joint, a protective clamping plate movably installed inside the fixed bracket, a protective spring movably installed between the protective clamping plate and the fixed bracket, a connecting shaft movably installed on the fixed bracket, a protective spring sheet movably installed on the connecting rod, a limit plate fixedly installed on the connecting rod, a connecting spring movably installed between the limit plate and the protective spring sheet, an installation thread fixedly pressed at the lower end of the connecting rod, and a connecting nut movably installed on the outer side of the installation thread. This circular annular pipe positioning and drilling fixture improves working speed and efficiency, reduces working difficulty, reduces working costs, and also reduces damage to the pipeline.

[0005] To address the aforementioned issues, existing patents offer solutions, but these solutions present the problem of inconvenience in adjusting the drilling position of the positioned pipe. When drilling at different locations on the pipe, existing positioning devices require repeated disassembly of the positioning device to limit the pipe before the drilling position can be adjusted. Additionally, they are not convenient for clamping and positioning pipes of different diameters.

[0006] To address this, an easily adjustable positioning device for drilling holes in rust-proof steel-aluminum composite pipes is proposed. Utility Model Content

[0028] 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.

[0029] Please see Figures 1 to 5 This utility model provides a technical solution:

[0030] A rust-proof steel-aluminum composite pipe drilling device with easy adjustment includes a base plate 1, a support positioning mechanism 2 for positioning the composite pipe is provided on the top of the base plate 1, an anti-slip clamping positioning mechanism 3 is provided on the top of the base plate 1, and a pre-support component 4 is provided on the top of the base plate 1.

[0031] The support positioning mechanism 2 includes a sliding frame 21, a bidirectional lead screw 22, a slider 23, a mounting frame 24, a support roller 25, a mounting bracket 26, an electric push rod 27, a top frame 28, a pressing roller 29, and a drive motor 210. The two sliding frames 21 are respectively fixedly connected to the top of both ends of the base plate 1. The bidirectional lead screw 22 is bearing-connected to the middle of the sliding frame 21. The two sliders 23 are movably disposed inside the sliding frame 21 and threadedly connected to the bidirectional lead screw 22. The mounting frame 24 is fixedly connected to the top of the slider 23. The support roller 25 is disposed in the middle of the mounting frame 24. The mounting bracket 26 is fixedly connected to the top of the slider 23. The electric push rod 27 is disposed on the top of the mounting bracket 26. The top frame 28 is fixedly connected to the output end of the electric push rod 27. The drive motor 210 is bolted to the side wall of the sliding frame 21 and its output end is fixedly connected to the bidirectional lead screw 22.

[0032] Specifically, such as Figure 1 As shown, the pre-support assembly 4 includes a mounting base 41 and a support block 42. The mounting base 41 is fixedly connected to the top of the base plate 1, and the support block 42 is fixedly connected to the top of the mounting base 41.

[0033] Specifically, such as Figure 1 As shown, a groove 8 is provided in the middle of the support block 42, and the top of the groove 8 is inclined.

[0034] Specifically, such as Figure 3 As shown, mounting feet 9 are fixedly connected to both ends of the base plate 1, and mounting grooves 10 are provided at both ends of the mounting feet 9.

[0035] Specifically, such as Figure 1 As shown, the bottom of the base plate 1 is provided with multiple reinforcing ribs 11, which are fixedly connected to the mounting feet 9.

[0036] In use, the mounting base 41 and support block 42 can pre-support and position the pipe. Connecting to an external power source starts the drive motor 210, which drives the bidirectional lead screw 22 to rotate. The bidirectional lead screw 22 moves threadedly through the slider 23, causing the slider 23 to slide inside the sliding frame 21. The movement of the slider 23 and the mounting frame 24 causes the support roller 25 to contact the pipe. Then, the electric push rod 27 pushes the top frame 28 downwards, causing the clamping roller 29 to contact the pipe. This process enables clamping and positioning of pipes of different sizes. When adjusting the drilling position of the pipe, the operator... The operator can simply hold and rotate the pipe. The support rollers 25 and clamping rollers 29 allow the pipe to be rotated and its position adjusted. The groove 8 allows the debris generated during drilling to be discharged from the center of the support block 42. The mounting feet 9 and mounting groove 10 allow the base plate 1 to be installed. In this way, pipes of different sizes can be supported and clamped for positioning. The angle of the clamped and positioned pipe can be adjusted, making it easy to adjust the drilling operation at different positions of the pipe. This improves the flexibility and efficiency of auxiliary pipe drilling.

[0037] Specifically, such as Figure 1 As shown, the anti-slip clamping and positioning mechanism 3 includes two electric push rods 31, a moving groove 32, a moving block 33, a clamping block 34, and a V-groove 35. The two electric push rods 31 are bolted to the bottom of the base plate 1. The two electric push rods 31 are located at both ends of the base plate 1 and are arranged opposite to each other. The two moving grooves 32 are opened at the top of the base plate 1. The moving block 33 is fixedly connected to the output end of the electric push rod 31 and is movably arranged inside the moving groove 32. The clamping block 34 is fixedly connected to the top of the moving block 33. The V-groove 35 is opened on the side wall of the clamping block 34.

[0038] Specifically, such as Figure 1 As shown, multiple anti-slip strips 5 are embedded on the side wall of the V-groove 35, and the multiple anti-slip strips 5 are set at equal intervals.

[0039] Specifically, such as Figure 1 As shown, the clamping block 34 is threadedly connected to a threaded rod 6 in the middle, and a tapered head 7 is provided at the top of the threaded rod 6.

[0040] In use, after the pipe is clamped and positioned, two electric push rods 31 are simultaneously activated to pull the moving block 33 to move inside the moving groove 32. This process drives the clamping block 34 to clamp and position the pipe through the V-groove 35. Since the two clamping blocks 34 apply opposing pulling forces to both ends of the pipe, it can effectively prevent the pipe from rotating and shifting when being drilled. The anti-slip strip 5 can increase the friction between the clamping block 34 and the pipe. Pushing the threaded rod 6 to make the conical head 7 contact the pipe can also increase the friction between the clamping block 34 and the pipe. In this way, after the pipe is supported and clamped and positioned, opposing clamping forces are applied to both ends of the pipe, which can effectively prevent the pipe from sliding and shifting when being drilled, thus improving the stability of the pipe clamping and positioning.

[0041] By adopting the above technical solution, the problem of existing circular pipe positioning and drilling fixtures being inconvenient to adjust the drilling position of the positioned pipe is solved. When drilling at different positions of the pipe, the existing positioning device needs to be disassembled repeatedly to limit the pipe before the drilling position of the pipe can be adjusted. At the same time, it is inconvenient to clamp and position pipes of different diameters.

[0042] Working principle: In use, this application firstly pre-supports and positions the pipe through the mounting base 41 and support block 42. Connecting to an external power source starts the drive motor 210, which drives the bidirectional lead screw 22 to rotate. The bidirectional lead screw 22 moves threadedly through the slider 23, causing the slider 23 to slide inside the sliding frame 21. The movement of the slider 23 and the mounting frame 24 causes the support roller 25 to contact the pipe. Then, the electric push rod 27 pushes the top frame 28 downwards, causing the clamping roller 29 to contact the pipe. This process enables clamping and positioning of pipes of different sizes. Next, two electric push rods 31 are simultaneously activated, pulling the moving block 33 to move inside the moving groove 32. This process drives the clamping block 34 through a V-shaped path. The groove 35 clamps and positions the pipe. Since the two clamping blocks 34 apply opposing pulling forces to both ends of the pipe, it can effectively prevent the pipe from rotating and shifting when being drilled. When adjusting the drilling position of the pipe, the electric push rod 31 drives the moving block 33 to reset and release the clamping limit on the pipe. The operator can then hold the pipe and rotate it. The support roller 25 and the clamping roller 29 allow the pipe to rotate and adjust its position. This allows for the support and clamping of pipes of different sizes, and facilitates the rotation and adjustment of the pipe after clamping and positioning. This makes it easy to adjust the drilling position of the pipe, improving the flexibility and efficiency of auxiliary pipe drilling.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
