[0022] The present invention discloses a cutter head for cleaning burrs on a pipe cut, which has the following technical effects:

[0023] When using conventional burr cleaning equipment to clean the pipeline, the cutter head is usually connected to the driver and fixedly set; in order to reduce the cost of the equipment and improve the practicality of the equipment, the conventionally designed cutter head can only be extended and retracted along the extension direction of the driver rotor when in use. In addition, it is also necessary to limit the pipeline so that the pipeline core is aligned with the axis of the cutter head, so as to facilitate the extension of the cutter head to reach the pipeline incision to clean the burrs. In the alignment process, due to the non-standard situation of the pipeline mouth, the pipeline incision has a certain deviation; and when the positioner is used to position the pipeline, when the pipe mouth is bent or the positioning is inaccurate, the relative position between the cutter head and the pipe mouth cannot be determined. In this embodiment, after the pipeline is positioned, the driver drives the cutter head to move toward the pipe mouth; when the pipe head of the pipeline is not aligned with the cutter head or the pipe mouth is non-standard, the inner wall of the pipeline cavity resists the positioner, so that the positioner drives the positioning body to deviate in the inner cavity of the positioning sleeve to adapt to the pipeline incision. Among them, the universal joint is used to limit the farthest travel of the positioning body in the positioning sleeve, and the elastic support is used to support the positioning body and provide a restoring elastic force for the positioning body. When using a cutter head to clean burrs on the inside and outside of the pipe incision, if the pipe is non-standard, it will resist the cutter head and drive the relative displacement of the positioning body, thereby adapting the non-standard pipe. This solves the technical problems in the prior art that the burrs at the pipe incision cannot be cleaned in a standardized or batch manner, the cleaning efficiency is low, and it is difficult to control the burr cleaning effect.

[0033] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0034] See also Figures 1 to 4 , a cutter head 10 for cleaning burrs on a pipe cut provided by an embodiment of the present invention, the cutter head 10 comprises: a positioning sleeve 11, a universal joint 12, a positioning body 13, an elastic support member 14, a blade assembly 15 and a positioner 16;

[0035] The positioning body 13 is disposed in the inner cavity of the positioning sleeve 11, and the outer diameter of the positioning body 13 is smaller than the inner diameter of the positioning sleeve 11;

[0036] The two ends of the universal joint 12 are respectively connected to the positioning body 13 and the positioning sleeve 11, and the universal joint 12 is used to limit the swing range of the positioning body 13 in the inner cavity of the positioning sleeve 11;

[0037] The elastic support member 14 is disposed in the positioning sleeve 11, and its two ends are respectively connected to the positioning sleeve 11 and the positioning body 13;

[0038] The positioner 16 is arranged on a side of the positioning body 13 away from the positioning sleeve 11;

[0039] The blade assembly 15 is disposed on the outer periphery of the positioner 16 and connected to the positioning body 13 .

[0040] Among them, the positioning sleeve 11 is used to connect with an external driver, and when the external driver rotates, the positioning sleeve 11 drives the cutter head 10 to rotate. The universal joint 12 is used to limit the maximum stroke of the positioning body 13 in the positioning sleeve 11, and the universal joint 12 is also used to limit the swing range of the positioning body 13 in the positioning sleeve 11. The elastic support 14 is used to support the positioning body 13 so that the positioning body 13 is in the positioning sleeve 11 and is in the maximum stroke position; when the positioning body 13 is subjected to external force, the elastic support 14 provides the positioning body 13 with elastic potential energy for recovery. It can be clearly seen that the cutting force of the blade group 15 on the burrs at the pipe cut can be changed by changing the elastic coefficient of the elastic support 14. The positioner 16 is used to align the core of the pipe, and the blade group 15 is used to clean the burrs at the inner wall or outer wall port of the pipe cut when the cutter head 10 rotates.

[0041] When using conventional burr cleaning equipment to clean the pipeline, the cutter head 10 is usually connected to an external driver and fixedly set; in order to reduce the cost of the pipeline burr cleaning machine and improve the practicality of the equipment, the conventional design of the cutter head 10 can only be extended and retracted along the axis direction of the external driver rotor. At the same time, the pipeline needs to be limited so that the pipeline core is aligned with the cutter head 10, so as to facilitate the cutter head 10 to reach the pipeline incision to clean the burrs. In the alignment process, due to the non-standard situation of the pipeline mouth, the pipeline incision has a certain deviation; and when the positioner 16 is used to position the pipeline, when the pipe mouth is non-standard or the pipe mouth positioning has a deviation, the relative position between the cutter head 10 and the pipe mouth cannot be determined. In this embodiment, after the pipeline is positioned, the driver drives the cutter head 10 to move toward the pipe mouth of the pipeline; when the pipe mouth of the pipeline is not aligned with the cutter head 10 or the pipe mouth is non-standard, the inner wall of the pipe cavity of the pipeline resists the positioner 16, so that the positioner 16 drives the positioning body 13 to deviate in the inner cavity of the positioning sleeve 11 to adapt to the pipe mouth of the pipeline. Among them, the universal joint 12 is used to limit the farthest travel of the positioning body 13 in the positioning sleeve 11, and the elastic support member 14 is used to support the positioning body 13; at the same time, the elastic support member 14 is also used to provide a restoring elastic force for the positioning body 13. When the cutter head 10 is used to clean the burrs on the inside and outside of the pipe cut, if the pipe is non-standard, it will push against the cutter head 10 and drive the relative displacement of the positioning body 13, and then adapt the non-standard pipe, and the burrs at the pipe cut can be cleaned by the cutter head 10. This solves the technical problems in the prior art that the burrs at the pipe cut cannot be cleaned in a standardized or batch manner, the cleaning efficiency is low, and it is difficult to control the burr cleaning effect.

Therefore, different elastic structures can be set according to specific application scenarios to achieve this effect. In this embodiment, the elastic support member 14 is a support spring 141, which facilitates the installation of the positioning body 13, has a simpler structure, and does not affect the function of the universal joint 12.

[0045] In order to increase the restoring potential of the positioning body 13 returning to the inner cavity center of the positioning sleeve 11 and ensure the cleaning force of the blade assembly 15 connected to the positioning body 13 on the burrs on the inner and outer walls of the pipe cut, a plurality of return spring assemblies 17 are provided.
