Description

Technical Field

[0001] This utility model relates to the field of pipe cutting technology, and in particular to an angle adjustment and positioning device for pipe bevel cutting. Background Technology

[0002] In the field of fluid transportation, pipelines, as tubular infrastructure used to transport various fluid media such as water, oil, and gas, are widely used in industries such as manufacturing, construction, and energy. Their materials include metals and non-metals, and they are assembled into complex transportation systems through welding, flange connections, and threaded connections. Pipelines require beveling because during pipeline installation and connection, when it is necessary to change the fluid flow direction, achieve transitions between pipes of different diameters, or arrange them compactly within a specific space, vertically cut pipe ends often cannot meet the requirements for angled connection, reduced fluid resistance, or optimized installation layout. Beveling creates a beveled surface at the pipe end and increases the contact area, improving connection strength and sealing during welding or flange connections. Furthermore, beveling in drainage pipelines can optimize water flow direction and prevent water stagnation. Therefore, beveling is an important technological means to ensure the functionality, stability, and ease of installation of pipeline systems.

[0003] Existing pipe beveling involves cutting pipes into ports with a specific angle according to engineering design requirements. During this process, the beveling angle directly affects the sealing of pipe connections and the smoothness of fluid transport. If the angle deviation is too large, it will cause gaps at the pipe joints.

[0004] To address this, an angle adjustment and positioning device for oblique pipe cutting is proposed. Utility Model Content

Detailed Implementation

[0024] 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.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] An angle adjustment and positioning device for pipe bevel cutting includes a placement platform 1, an auxiliary structure 2 bolted to the inner side of the placement platform 1, a support frame 3 bolted to the rear side of the top of the placement platform 1, and a positioning structure 4 fixedly connected to the top of the placement platform 1.

[0027] The positioning structure 4 includes a fixed post 41, a dial 42, a rotating rod 43, a support rod 44, a positioning element 45, and a fastener 46. The bottom of the fixed post 41 is fixedly connected to the rear side of the top of the placement platform 1. The top of the placement platform 1 is bolted to the bottom of the dial 42. The inner wall of the dial 42 is rotatably connected to the outer wall of the rotating rod 43. The top of the rotating rod 43 is fixedly connected to the bottom of the support rod 44. The outer side of the support rod 44 is movably connected to the inner side of the positioning element 45. The inner wall of the positioning element 45 is threadedly connected to the outer wall of the fastener 46. The right side of the fastener 46 is movably connected to the left side of the support rod 44.

[0028] In this embodiment: The placement platform 1 serves as the foundation of the entire device, providing a stable mounting platform for the auxiliary structure 2, support frame 3, and positioning structure 4. The support frame 3 provides support points for the pipes and, together with the auxiliary structure 2, forms a multi-point support frame. The positioning structure 4, with its fixed column 41 providing the mounting base for components such as the dial 42 and rotating rod 43, securely mounts the positioning structure 4 onto the placement platform 1. The dial 42 has markings on its surface to display the rotation angle of the rotating rod 43, providing an intuitive angle reference for the operator. The rotating rod 43 is fixed to the dial 4 on its support. The pointer, when rotated, drives the support rod 44 and the positioning element 45 to rotate, thereby positioning the pipe cutting angle. The support rod 44 transmits the rotational motion of the rotating rod 43 to the positioning element 45 and provides support for the positioning element 45. The positioning element 45 can slide up and down on the outside of the support element to adapt to pipes of different diameters. The rotation of the positioning element 45 can stop at the predetermined cutting angle position. The user can use the positioning element 45 to mark the pipe by pointing it at the top of the pipe. The fastener 46 can be used to firmly fix the positioning element 45 to the support rod 44 by rotating the fastener 46.

[0029] Specifically, such as Figure 3 , Figure 4 , Figure 5 As shown, the auxiliary structure 2 includes a stabilizing block 21, the outer side of which is inserted into the inner side of the placement platform 1.

[0030] Specifically, such as Figure 3 , Figure 4 , Figure 5 As shown, a threaded rod 22 is rotatably connected to the inner wall of the stabilizing block 21, and a mounting block 23 is rotatably connected to the outer wall of the threaded rod 22. The outer side of the mounting block 23 is bolted to the inner side of the placement platform 1.

[0031] Specifically, such as Figure 3 , Figure 4 , Figure 5 As shown, a movable block 24 is threadedly connected to the outer wall of the threaded rod 22, and a stabilizing frame 25 is bolted to the top of the movable block 24.

[0032] In this embodiment: by setting up an auxiliary structure 2, in which the inner wall of the stabilizing block 21 is rotatably connected to the threaded rod 22, the threaded rod 22 is provided with a foundation for installation and rotational stability. By rotating the threaded rod 22, the rotational motion can be converted into the linear motion of the moving block 24, thereby driving the stabilizing frame 25 to move, realizing auxiliary support and position adjustment for the pipeline. The mounting block 23 firmly installs the auxiliary structure 2 on the placement platform 1, and at the same time provides rotational support for the threaded rod 22. Driven by the threaded rod 22, the moving block 24 can move linearly along the axis of the threaded rod 22, driving the top stabilizing frame 25 to move, realizing the adjustment of the pipeline support position. The stabilizing frame 25 provides clamping support for the pipeline, preventing the pipeline from shaking or displacing due to uneven force during the cutting process.

[0033] Specifically, such as Figure 2 As shown, a threaded hole 5 is provided on the left side of the positioning member 45, and the fastener 46 is threaded through the left side of the positioning member 45 and contacts the left side of the support rod 44.

[0034] Specifically, such as Figure 1 As shown, a T-shaped groove 6 is provided on the front side of the placement platform 1. The inner side of the T-shaped groove 6 is movably connected to the outer side of the stabilizing block 21, and the inner side of the T-shaped groove 6 is bolted to the outer side of the mounting block 23.

[0035] In this embodiment: the threaded hole 5 of the positioning member 45 allows the fastener 46 to be threadedly connected to the inner wall of the positioning member 45, thereby positioning the positioning member 45. The T-slot 6 of the placement platform 1 connects to the stabilizing block 21 and the mounting block 23 in the auxiliary structure 2, thereby enabling the installation and position adjustment of the auxiliary structure 2.

[0036] Specifically, such as Figure 1 , Figure 5 As shown, anti-slip blocks 7 are fixedly connected to the inner sides of both the support frame 3 and the stabilizer 25, and a rectangular hole is opened on the top of the positioning component 45.

[0037] Specifically, such as Figure 1 , Figure 5 As shown, a support block 8 is fixedly connected to the bottom of the placement platform 1. There are four support blocks 8, which are respectively set at the bottom of the placement platform 1.

[0038] In this embodiment: by setting the anti-slip block 7 to be made of rubber, the friction of clamping the pipe is increased, preventing the pipe from shaking or displacing due to uneven force during the cutting process. The rectangular hole opened by the positioning member 45 can be used to install the positioning member 45 on the outside of the support rod 44. By setting the support block 8, the stability of the device is enhanced, preventing the device from tilting or shifting during operation.

[0039] Working Principle: When cutting pipes, the pipe is first placed between the support frame 3 and the stabilizing frame 25 of the auxiliary structure 2. The anti-slip blocks 7 on the inner sides of both increase friction and prevent the pipe from shaking. For the positioning structure 4, the operator can rotate the rotating rod 43, which drives the support rod 44 and the positioning piece 45 to rotate around the scale 42. The pointer on the rotating rod 43 cooperates with the scale 42 to visually display the rotation angle, thereby adjusting to the required pipe cutting angle. The positioning piece 45 can slide up and down on the outside of the support rod 44 to adapt to pipes of different diameters. After adjusting the position and angle, the fastener 46 is rotated to pass through the threaded hole 5 of the positioning piece 45 and press against the support rod 44 to firmly fix the positioning piece 45. The user then marks the top of the pipe with the positioning piece 45 to provide a clear mark for cutting. Regarding the auxiliary structure 2, rotating the threaded rod 22 converts its rotational motion into linear motion of the moving block 24 along the axial direction, which drives the stabilizing frame 25 to move, thereby adjusting the pipe support position and ensuring that the pipe is stably supported, completing the positioning and stabilizing support before the pipe is cut at an angle.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
