[0016] Figure 2 is a schematic structural diagram of the driving mechanism, the cutting mechanism and the track assembly of the utility model. Detailed Embodiments

[0017] In order to make the technical means, creative features, achieved purposes and effects of the utility model easy to understand, the utility model will be further described below in conjunction with specific embodiments.

[0018] Please refer to Figure 1 and Figure 2 , the utility model provides a technical solution for a device for cutting thin-walled pipe fittings without chips: including a driving mechanism 1, a cutting mechanism 2, and a track assembly 3;

[0019] The driving mechanism 1 includes two rotating rollers 11 rotating in the same direction, a driving motor 12, a conveyor belt 14, a base 13, and a placement opening 17; the two rollers 11 act on the pipe fitting 4 to rotate the pipe fitting 4; specifically, the rollers 11 are installed on the base 13 through bearings; the driving motor 12 drives the two rollers 11 to rotate through the conveyor belt 14, thereby rotating the pipe fitting 4.

[0020] To prevent the rollers 11 from slipping with the conveyor belt 14, a first guide wheel 15 and a second guide wheel 16 are provided on the base 13; the first guide wheel 15 is located between the rollers 11 and is offset outward, and the conveyor belt 14 passes through the first guide wheel 15; thus, the contact area between the conveyor belt 14 and the rollers 11 is increased, and the friction force is increased accordingly. The second guide wheel 16 is slidably installed on the base 13; the second guide wheel 16 presses against the conveyor belt 14 and is fixed to the base 13 through hardware components; thus, the sliding position of the second guide wheel 16 on the base 13 can be used to adjust the tightness of the conveyor belt 14 on the rollers 11.

[0021] One side of the base 13 corresponding to the cutting mechanism 2 is provided with a placement opening 17; the placement opening 17 corresponds to the central axis between the two rollers 11; the placement opening 17 is used to place the pipe fitting 4, and the placement opening 17 is semi-circular; since the radius of the placement opening 17 is greater than the radius of the pipe fitting 4, the pipe fitting 4 can be easily placed in the placement opening 17, and the radius of the placement opening 17 is less than the radius of the rollers 11, so that the rollers 11 can act on the pipe fitting 4.

[0022] Preferably, the cutting mechanism 2 includes a plurality of cutters 21, rollers 22, a spring (not shown in the figure), and 23; the cutters 21 act on the pipe fitting 4; the rollers 22, cutters 21, and spring are all installed on 23; the cutters 21 are wheel-shaped; the spring acts on the rollers 22; on the side facing the driving mechanism 1, the protruding length of the rollers 22 is greater than the protruding length of the cutters 21; thus, when cutting operations are performed, the rollers 22 first press against the pipe fitting 4 in combination with the placement opening 17 to stabilize the pipe fitting 4, and then as the cutting mechanism 2 approaches continuously, the cutters 21 squeeze and cut the pipe fitting 4.

[0023] The track assembly 3 includes a linear slide rail 31, a first slide seat 32 for installing the driving mechanism 1, and a second slide seat 33 for installing the cutting mechanism 2; the first slide seat 32 is fixedly installed on the linear slide rail 31 through hardware components, so that the second slide seat 33 can slide, and thus the cutters 21 can operate on the pipe fitting 4.

[0024] Further, to prevent the cutting knife 21 from sliding too deep and contacting the rotating roller 11, a limiting plate 34 is provided on the surface of the first sliding seat 32 facing the second sliding seat 33. On the surface of the limiting plate 34 facing the cutting mechanism 2, the protruding length of the limiting plate 34 is greater than the protruding length of the roller 22. In this way, the limiting plate 34 can limit the sliding distance of the second sliding seat 33 and the operating depth of the cutting knife 21, preventing the cutting knife 21 from contacting the rotating roller 11.

[0025] In one embodiment, the cutting mechanism 2 is pushed manually or by a cylinder, so that the cutting mechanism 2 is displaced on the linear slide rail 31 relying on the second sliding seat 33.

[0026] Working principle: Manually place the pipe fitting 4 in the placement opening 17 and hold it. Then, push the cutting mechanism 2 towards the driving mechanism 1 (pipe fitting 4). During this process, when the roller 22 abuts against the pipe fitting 4, release the pipe fitting 4 manually, and then the cutting mechanism 2 continues to move forward. In this way, the cutting knife 21 contacts the rotating pipe fitting 4 (the pipe fitting 4 is driven by the rotating roller 11 to rotate) to perform circumferential cutting.
