Detailed Implementation

[0029] The technical solutions of this application will be further described below with reference to specific embodiments, but this application is not limited to these embodiments.

[0030] like Figures 1 to 5 As shown, this embodiment proposes a pipe chamfering mechanism, including:

[0031] Drive element 11, drive element 11 has a rotatable output shaft;

[0032] Rotary disk 12 is fixed on the output shaft of drive component 11, and chamfering plate assembly 13 is fixed on rotary disk 12;

[0033] The linear motion assembly 14 has a moving platform 15 that moves in a straight line, and a clamping assembly 16 is fixed on the moving platform 15 for clamping the pipe 17.

[0034] In this design, the clamping assembly 16 clamps the tube 17, and the linear motion assembly 14 pushes the tube 17 forward, allowing the tube 17 to fully contact the chamfering plate assembly 13. The driving component 11 drives the chamfering plate assembly 13 to rotate fully via the rotating disk 12, thereby grinding the end of the tube 17 and chamfering the edge of the tube 17.

[0035] In this solution, the drive component 11 can be a motor, a geared motor, or a combination of a geared motor and a geared motor, which are existing technologies. Since this pertains to existing technology, its specific structure will not be described in detail.

[0036] The linear motion component 14 in this solution can be a linear motor, a rodless cylinder, or a lead screw and slider mechanism.

[0037] Furthermore, it also includes a mounting plate 35 for mounting the linear motion component 14, and a support frame 36 is provided on the mounting plate 35 for mounting the drive component 11.

[0038] When the linear motion component 14 adopts a lead screw and slider mechanism, a drive motor is needed to drive the lead screw to rotate. This part is also existing technology. For the specific working principle and specific structure, please refer to the existing technology.

[0039] In one embodiment of this invention, the axis of the rotating disk 12 and the axis of the tube 17 are on the same straight line.

[0040] The chamfering plate assembly 13 includes a first chamfering plate 18 and a second chamfering plate 19. The first chamfering plate 18 and the second chamfering plate 19 are respectively mounted on the rotating disk 12 by fixing blocks 20. The first chamfering plate 18 has a first grinding bevel 32 for grinding the outer edge of the tube 17, and the second chamfering plate 19 has a second grinding bevel 33 for grinding the inner edge of the tube 17.

[0041] Furthermore, the first chamfering piece 18 and the second chamfering piece 19 are mounted on the same or different fixing blocks 20 by means of threaded parts or welding. The technical advantage of this solution is that it can simultaneously chamfer the inner and outer rings of the pipe 17 in one operation.

[0042] The rotating disk 12 is provided with a mounting groove for mounting the fixing blocks 20. There are three fixing blocks 20. The three fixing blocks 20 can be arranged separately, and the ends of the three fixing blocks 20 near the axis of the rotating disk 12 can also be connected together.

[0043] The three fixing blocks 20 are respectively welded into the mounting slots of the rotating disk 12.

[0044] As one embodiment of this invention, the clamping assembly 16 includes:

[0045] Support base, which is fixed on the mobile platform 15;

[0046] Positioning component 21 is fixed on the support base, and the top of the positioning component 21 is provided with a notch 22 for installing the pipe 17.

[0047] The clamping member 23 is mounted on the support base. The clamping member 23 has a pressure plate 24, which is located above the recess 22 and is used to clamp the pipe material 17 in the recess 22.

[0048] The support base includes a first horizontal plate 25, a first vertical plate 26, and a second horizontal plate 27. The second horizontal plate 27 is fixed to the upper surface of the first horizontal plate 25 through the first vertical plate 26. The first horizontal plate 25 is fixed on the mobile platform 15.

[0049] As one embodiment of this invention, the clamping member 23 includes:

[0050] Telescopic member 28 is mounted on the second transverse plate 27 and has a piston rod 29 that moves in the vertical direction. The top of the piston rod 29 is hinged to one end of the pressure plate 24.

[0051] The second vertical plate 37 is fixed on the second horizontal plate 27;

[0052] The hinge plate 30 is hinged at one end to the middle or one-third of the pressure plate 24, or it can be installed at other positions on the pressure plate 24, but these positions are spaced apart from the end of the pressure plate 24 away from the telescopic member 28. The other end of the hinge plate 30 is hinged to the second vertical plate 37.

[0053] The telescopic component 28 in this design uses a pneumatic cylinder, hydraulic cylinder, or electric cylinder.

[0054] When the piston rod 29 in the telescopic component 28 moves vertically, it will cause the pressure plate 24 to rotate and swing, which facilitates the clamping of the tube 17 in the notch 22.

[0055] As one embodiment of this invention, the linear motion assembly 14 is provided with two moving platforms 15. One moving platform 15 is used to install the clamping assembly 16, and the other moving platform 15 is fixed with a clamping plate 31, which is used to clamp the end of the tube 17.

[0056] Furthermore, the clamping plate 31 is provided with a collar 34, which is used for inserting and installing the pipe 17.

[0057] Additionally, this solution can include two moving platforms 15. When the linear motion component 14 is a lead screw and slider mechanism, a drive motor is needed to drive the lead screw. To facilitate understanding of this part, this paper provides a detailed explanation of the existing technology, as follows:

[0058] The linear motion assembly 14 includes a base plate with fixed plates at both ends. A lead screw is rotatably mounted between the two fixed plates. A drive motor is mounted on the fixed plates, and the output shaft of the drive motor is connected to the lead screw via a coupling to drive the lead screw to rotate in the forward or reverse direction. Two nuts are mounted on the lead screw, and a moving platform 15 is fixed to each nut. Each moving platform 15 is mounted on the base plate via a guide rail assembly. When the drive motor rotates in the forward or reverse direction, it can drive the two moving platforms 15 to move synchronously.

[0059] Alternatively, a larger moving platform 15 can be provided, in which case the clamping assembly 16 and the abutment plate 31 are mounted on the same larger moving platform 15.

[0060] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
