DETAILED DESCRIPTION

[0031] The technical solution of the present application is further described below in conjunction with specific embodiments, but the present application is not limited to these embodiments.

[0032] like Figures 1 to 6 As shown, this embodiment provides a pipe cutting device, comprising:

[0033] A workbench 11, the upper end of which is provided with a supporting surface 12,

[0034] a cutting mechanism 13 , the cutting mechanism 13 being mounted on the support surface 12 and having a cutting portion 15 for cutting the tube material 14 ;

[0035] A clamping mechanism 16 includes a rotating cylindrical shell 17 and a clamping assembly 18. The clamping assembly 18 is disposed in the rotating cylindrical shell 17 and is used to clamp the pipe material 14. The rotating cylindrical shell 17 is rotatably mounted on the support surface 12 via a mounting seat 19.

[0036] The rotary drive mechanism 20 is installed on the support surface 12 and is used to drive the rotating shell 17 to rotate.

[0037] The technical effect of this solution is that the clamping mechanism 16 is used to clamp the pipe material 14, and the rotary drive mechanism 20 drives the rotating cylinder shell 17 to rotate, thereby driving the pipe material 14 to rotate, making it easier for the cutting mechanism 13 to perform circular cutting on the pipe material 14, thereby making the cutting of the pipe material 14 more uniform.

[0038] Furthermore, the cutting portion 15 may adopt a laser cutting head or a saw blade in the prior art.

[0039] As an implementation of this embodiment, a driven gear 21 is provided on the outer periphery of the rotating cylindrical shell 17 , and the rotation driving mechanism 20 is used to drive the driven gear 21 to rotate.

[0040] Furthermore, the rotation drive mechanism 20 includes a driving gear 22 and a reduction motor 23. The reduction motor 23 is mounted on the support surface 12 via a support. The driving gear 22 is fixed on the driving shaft of the reduction motor 23. The driving gear 22 is transmission-connected to the driven gear 21.

[0041] In addition, the rotation drive mechanism 20 can also be in the form of a rack, such as the rack is meshed with the driven gear 21, and the rack is driven by a cylinder, so that the rack can reciprocate in a straight line direction, thereby driving the driven gear 21 to rotate.

[0042] As an implementation of this embodiment, an inner cylindrical shell 24 is provided inside the rotating cylindrical shell 17. The inner cylindrical shell 24 is coaxially arranged with the rotating cylindrical shell 17. One end of the inner cylindrical shell 24 along its own axial direction is fixedly connected to the rotating cylindrical shell 17 through an annular plate 25.

[0043] As an implementation of this embodiment, the clamping assembly 18 includes:

[0044] An intermediate cylindrical shell 26, which is sleeved on the outer periphery of the inner cylindrical shell 24;

[0045] A clamping plate 27, one end of which is rotatably mounted on an end of the inner cylindrical shell 24 away from the annular plate 25, wherein the clamping plate 27 is mounted via a rotating shaft, and the other end of the clamping plate 27 is provided with an escape channel 28;

[0046] a limiting rod 29 , which passes through the avoidance passage 28 and is fixed to an end of the intermediate cylinder shell 26 away from the annular plate 25 ;

[0047] A notch is provided on one side of the avoidance channel 28 away from the axis of the pipe material. The notch is used to avoid rotation. When the clamping plate 27 rotates, the rotating shaft can be separated from the notch to avoid interference.

[0048] The telescopic member 30 has one end hingedly mounted on the intermediate cylindrical shell 26 , and the other end hingedly mounted on the inner wall of the rotating cylindrical shell 17 .

[0049] Wherein the telescopic member 30 adopts an electric cylinder, which has the advantages of simple driving and fast reaction efficiency. In addition, the telescopic member 30 can also adopt an air cylinder.

[0050] As an implementation of this embodiment, the clamping plate 27 is arranged on the inner cylindrical shell 24 through a mounting shaft. The clamping plate 27 is arc-shaped.

[0051] In one embodiment of this invention, there are multiple clamping plates 27, each of which is evenly distributed in a circular array about the axis of the inner cylindrical shell 24. The central portions of the multiple clamping plates 27 form a receiving opening, through which the pipe 14 is passed. The movement of the intermediate cylindrical shell 26 causes each clamping plate 27 to move, causing the opening area of ​​the receiving opening to change.

[0052] The clamping plates 27 have avoidance notches 33 to prevent interference between adjacent clamping plates 27 during movement. Between two adjacent clamping plates 27, the avoidance notch 33 on one clamping plate 27 can effectively provide movement space for the other clamping plate 27.

[0053] As an implementation of this embodiment, a pushing mechanism is further included, and the pushing mechanism is used to drive the pipe material 14 to move along its own axis direction.

[0054] As an implementation of this embodiment, the pushing mechanism includes a reciprocating motion mechanism 31 and a clamping module 32. The clamping module 32 is used to clamp the pipe material 14. The reciprocating motion mechanism 31 is used to drive the clamping module 32 to perform reciprocating linear motion along the axial direction of the pipe material 14.

[0055] Furthermore, the reciprocating motion mechanism 31 adopts a linear motor in the prior art, which has a mobile platform capable of reciprocating motion, on which a clamping module 32 is mounted. The clamping module 32 has the same structure as the clamping mechanism 16 .

[0056] In addition, the reciprocating motion mechanism 31 adopts the existing technology solution content to supplement the description, specifically including a screw slider, and the screw slider is driven by a servo motor.

[0057] Furthermore, a control system is included, which is used to control the operation of the clamping module 32, the clamping mechanism 16, the linear motor, the rotary drive mechanism 20 and the cutting mechanism 13. The control system can adopt a PLC control system or a single-chip microcomputer control system in the prior art to control the cutting and feeding automation operations.

[0058] This solution works as follows:

[0059] Step 1: Manually insert the pipe 14 into the receiving openings of the clamping module 32 and the clamping mechanism 16. The controller controls the clamping mechanism 16 and the clamping module 32 to simultaneously clamp the pipe 14. In this embodiment, only one rotary drive mechanism 20 is provided. The rotary drive mechanism 20 drives the driven gear 21 on the rotating cylindrical shell 17 of the clamping mechanism 16 in a forward direction to adjust the rotation of the pipe 14, thereby facilitating the cutting mechanism 13 to cut the pipe 14. Since the length of the first pipe 14 cut may not meet the standard, the first cut pipe 14 is deemed waste.

[0060] Step 2: The clamping mechanism 16 releases the pipe 14, and the linear motor drives the clamping module 32 to move a specified distance toward the clamping mechanism 16. The clamping mechanism 16 then clamps the pipe 14, and the clamping module 32 releases the pipe 14. At the same time, the linear motor drives the clamping module 32 back to its initial position, and the clamping module 32 clamps the pipe 14 again. The rotary drive mechanism 20 drives the driven gear 21 on the rotating cylindrical shell 17 in the clamping mechanism 16 in the opposite direction to adjust the rotation of the pipe 14, so that the cutting mechanism 13 can cut the pipe 14. After cutting is completed, step 2 is repeated. The length of each pipe 14 cut in step 2 is the same as the length of the linear motor movement, which can ensure the processing quality of the pipe 14.

[0061] In addition, since the pipe 14 is relatively long, a support frame is provided at one end of the pipe 14 and the cutting mechanism 13 .

[0062] In addition, the rotation drive mechanism 20 drives the rotating cylindrical shell 17 to rotate forward and reverse alternately, and the angle of each unidirectional rotation is 360°.

[0063] For those skilled in the art, several variations and improvements can be made without departing from the inventive concept of the present invention, and all of these fall within the scope of protection of the present invention.
