Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, and in particular to a pipeline beveling device. Background Technology

[0002] When connecting some plastic pipes, it is necessary to bevele the pipes so that they can be joined together. During the beveling process, the pipe and the cutter are rotated relative to each other, and the cutter applies force to complete the beveling. However, because plastic pipes have low strength, the force exerted on the pipe when the cutter forms the bevel can cause the pipe to deform, thus affecting the beveling process. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where the cutting blade exerts force on the pipe when forming a bevel, causing pipe deformation and thus affecting the beveling process. Therefore, this invention proposes a pipe beveling device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A pipe beveling device is designed, comprising a base, a side plate fixedly connected to the base, a rotating shaft rotatably connected to the side plate via bearings, a plurality of connecting sleeves fixedly connected at equal intervals around the circumference of the rotating shaft, a connecting post provided inside each of the plurality of connecting sleeves, an abutment strip fixedly connected to each of the plurality of connecting posts, a hinge rod hinged to each of the plurality of abutment strips, a movable sleeve hinged to each of the plurality of hinge rods, the movable sleeve being moved by a moving mechanism, a telescopic rod fixedly connected to the base, a cutter fixedly connected to the telescopic rod, and a motor mounted on the side plate, the motor being drively connected to the rotating shaft.

[0006] Preferably, a collection box is placed on the base.

[0007] Preferably, the moving mechanism includes a threaded rod, which is rotatably connected to the rotating shaft via a bearing, and the thread on the threaded rod passes through the moving sleeve.

[0008] Preferably, the motor is a low-speed motor.

[0009] Preferably, a rotating block is fixedly connected to the threaded rod, an abutting block is abutted on the rotating block, a spring is fixedly connected to the abutting block, a fixing lug is fixedly connected to the spring, and the fixing lug is fixedly connected to the rotating shaft.

[0010] Preferably, a pull rod is fixedly connected to the abutment block, and the pull rod passes through the fixed lug.

[0011] Preferably, a pulling block is fixedly connected to the pulling rod.

[0012] The beneficial effects of the pipe beveling device proposed in this utility model are as follows: by moving the position of the moving sleeve through the moving mechanism, the inclination of the adjusting hinge rod is adjusted, so that the hinge rod drives multiple abutment strips to move, and the multiple abutment strips abut against the inner wall of the pipe. During beveling, it plays a supporting role for the internal part of the pipe and prevents the cutting blade from causing the pipe to deform and affecting the processing effect.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example 1: Refer to Figure 1-4A pipe beveling device includes a base 1, a side plate 2 fixedly connected to the base 1, a rotating shaft 5 rotatably connected to the side plate 2 via bearings, and multiple connecting sleeves 9 fixedly connected at equal intervals around the rotating shaft 5. Each connecting sleeve 9 contains a connecting post 8, which, along with the connecting sleeves 9, limits the movement of an abutment strip 7, ensuring that the abutment strip 7 can only move radially along the rotating shaft 5. Each connecting post 8 has an abutment strip 7 fixedly connected to it, and each abutment strip 7 is hinged to a hinge rod 10. Each hinge rod 10 is hinged to a movable sleeve 12, which is connected to a movable sleeve via a sliding mechanism. The moving mechanism moves, and a telescopic rod 4 is fixedly connected to the base 1. A cutter 18 is fixedly connected to the telescopic rod 4. The moving mechanism moves the position of the moving sleeve 12, thereby adjusting the tilt of the hinge rod 10. This causes the hinge rod 10 to drive multiple abutment strips 7 to move, and the multiple abutment strips 7 to abut against the inner wall of the pipe. During beveling, this provides support for the inside of the pipe and prevents the cutter 18 from causing deformation of the pipe and affecting the processing effect. At the same time, it also fixes the pipe so that it can rotate.

[0020] A motor 3 is installed on the side plate 2. The motor 3 is a low-speed motor. The motor 3 is connected to the rotating shaft 5. When the motor 3 rotates, it drives the rotating shaft 5 to rotate, thereby driving the pipe to rotate.

[0021] A collection box 6 is placed on the base 1 to collect the generated debris.

[0022] The moving mechanism includes a threaded rod 11, which is rotatably connected to the rotating shaft 5 via a bearing. The threaded rod 11 has a thread that passes through the moving sleeve 12. By rotating the threaded rod 11, the position of the moving sleeve 12 on the threaded rod 11 is adjusted, thereby driving the moving sleeve 12 to move. The moving sleeve 12 is sleeved on the rotating shaft 5.

[0023] Example 2: In Example 1, when the shaft 5 rotates, the threaded rod 11 is prone to rotate, affecting the contact effect of the abutment strip 7 on the pipe. (Refer to...) Figure 1-4 In another preferred embodiment of this utility model, based on embodiment 1, a rotating block 14 is fixedly connected to the threaded rod 11, an abutting block 15 is abutted on the rotating block 14, and a spring 13 is fixedly connected to the abutting block 15. The spring 13 is in a compressed state, and a fixing ear 17 is fixedly connected to the spring 13. The fixing ear 17 is fixedly connected to the rotating shaft 5. Through the restoring force of the spring 13, the abutting block 15 is firmly abutted against the rotating block 14, which increases the friction when the rotating block 14 rotates, thereby preventing the threaded rod 11 from rotating when the rotating shaft 5 rotates.

[0024] A pull rod 16 is fixedly connected to the abutment block 15. The pull rod 16 passes through the fixed lug 1. A pull block is fixedly connected to the pull rod 16. When it is necessary to release the rotation of the threaded rod 11, the pull block is pulled to drive the pull rod 16 to move, so that the abutment block 15 and the rotating block 14 are separated, so as to grasp the rotating block 14 to drive the threaded rod 11 to rotate.

[0025] During beveling, the pipe is fitted onto the abutment strip 7, and the pulling block is pulled to move the pulling rod 16, causing the abutment block 15 to move away from the rotating block 14. The rotating block 14 is held to rotate the threaded rod 11, and the position of the adjusting sleeve 12 on the threaded rod 11 is adjusted to move the adjusting sleeve 12. The inclination of the hinge rod 10 is adjusted so that the hinge rod 10 moves multiple abutment strips 7, which then abut against the inner wall of the pipe. The motor 3 rotates, causing the pipe to rotate, and the telescopic rod 4 extends, causing the cutter 18 to abut against the end of the pipe, thus beveling the pipe.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
