[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Reference Figures 1-4 As shown, the utility model provides a pipe positioning and cutting device for mining machinery production, including a support plate 1, and a setting drive mechanism 2, a fixing mechanism 4 and a cutting mechanism 3 are provided on the upper end of the support plate 1. The setting drive mechanism 2 is used to place the pipe while driving the pipe to rotate, the fixing mechanism 4 is used to fix the pipe on the upper end of the setting drive mechanism 2 to prevent vibration during cutting, and the cutting mechanism 3 is used to cut the pipe; when working, the pipe is placed on the setting drive mechanism 2, and then the pipe above the setting drive mechanism 2 is fixed by the fixing mechanism 4, and then the pipe is cut by starting the cutting mechanism 3. During the cutting process, the pipe is rotated by the setting drive mechanism 2 to complete the cutting of the pipe, thereby solving the problem that vibration is easily generated when cutting the pipe, making it difficult to achieve an accurate cutting effect.

[0024] In a further embodiment, referring to Figure 2-Figure 4The driving mechanism 2 includes a supporting roller 23 and a driving device 24. The upper ends of the left and right sides of the supporting plate 1 are fixedly connected with mounting seats 21. Two groups of mounting seats 21 are provided and are located on the front and rear sides of the supporting plate 1. The mounting seat 21 is rotatably connected to the internal part of the rotating shaft 22. The side wall of the rotating shaft 22 is fixedly connected to the supporting roller 23. The pipe is placed on the upper end of the supporting roller 23. The driving device 24 includes a first motor 241 and a pulley assembly 242. The upper end of the support plate 1 is fixedly connected to the first motor 241. The output shaft end of the first motor 241 is connected to the left side wall of the supporting roller 23 through the pulley assembly 242.

[0025] In this embodiment, the pipe is placed on the support roller 23 and the fixing mechanism 4 is started before the pipe is cut, so that the pipe is fixed on the support roller 23. Then the first motor 241 is started. Since the output shaft end of the first motor 241 is connected to the left side wall of the support roller 23 through the pulley assembly 242, the support roller 23 is driven to rotate. The rotation of the support roller 23 drives the pipe to rotate, thereby facilitating the cutting of the pipe.

[0026] In a further embodiment, referring to Figure 3-Figure 4 The fixing mechanism 4 includes a support frame 41 and a lifting plate 43. The upper end of the support plate 1 is fixedly connected to the support frame 41, and the support frame 41 is located behind the supporting roller 23 on the left side of the support plate 1. The lower end of the support frame 41 is rotatably connected to the second threaded rod 42, and the lower end of the second threaded rod 42 is rotatably connected to the upper end of the support plate 1. The side wall of the second threaded rod 42 is threadedly connected to the lifting plate 43. The lower end of the support frame 41 is fixedly connected to the limiting rod 45, and the lower end of the limiting rod 45 is fixedly connected to the upper end of the support plate 1. The limiting rod 45 passes through the lifting plate 43 and is slidably connected thereto. The upper end of the support frame 41 is fixedly connected to the third motor 46, and the output shaft end of the third motor 46 is fixedly connected to the upper end of the second threaded rod 42. The lower end of the lifting plate 43 is rotatably connected to the pressure roller 44 through the bearing seat. The pressure roller 44 is provided with two groups and is located at the front and rear sides of the lifting plate 43. The pressure roller 44 is located directly above the support roller 23.

[0027] In this embodiment, by starting the third motor 46, the second threaded rod 42 is driven to rotate, and the rotation of the second threaded rod 42 drives the lifting plate 43 to move downward, and the downward movement of the lifting plate 43 drives the pressure roller 44 to move downward. When the side wall of the pressure roller 44 abuts against the side wall of the pipe, the movement of the pipe can be restricted, thereby solving the problem that vibration is easily generated when cutting the pipe, making it difficult to achieve an accurate cutting effect.

[0028] In a further embodiment, referring to Figure 2-Figure 3The cutting mechanism 3 includes a first threaded rod 32 and a cutter 36. The upper end of the support plate 1 is fixedly connected to the support column 31. The front end surface of the support column 31 is provided with a slide groove 311. The inside of the slide groove 311 is slidably connected to the lifting rod 34. The lower end of the front side of the lifting rod 34 is fixedly connected to the connecting rod 35. The lower end of the connecting rod 35 is provided with a cutter 36. The inside of the slide groove 311 is rotatably connected to the first threaded rod 32. The first threaded rod 32 passes through the lifting rod 34 and is threadedly connected to it. The upper end of the support column 31 is fixedly connected to the second motor 33. The output shaft end of the second motor 33 is fixedly connected to the upper end of the first threaded rod 32.

[0029] In this embodiment, the second motor 33 is started to drive the first threaded rod 32 to rotate, and the rotation of the first threaded rod 32 drives the lifting rod 34 to move downward, and the downward movement of the lifting rod 34 drives the connecting rod 35 to move downward, and the downward movement of the connecting rod 35 drives the cutting machine 36 to move. The cutting machine 36 is started before the cutting machine 36 moves downward, and the cutting machine 36 that moves downward can cut the pipe and cooperate with the rotation of the pipe, so as to achieve the purpose of cutting the pipe.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
