DETAILED DESCRIPTION

[0031] The technical solutions of the application will be described clearly and completely in connection with the embodiments. Obviously, the described embodiments are only some of the embodiments of the application, but not all the embodiments. Based on the embodiments in the application, all the other embodiments obtained by those skilled in the art without creative work are within the protection scope of the application.

[0032] Referring to Figure 3 , at present, the cutting tool of the optical rod 900 shearing device is fixed, and the optical rod 900 is sheared by the cutting tool every time the optical rod 900 moves downward by a certain distance. Since the cutting tool is fixed and the optical rod 900 moves, the cutting tool will generate radial resistance to the optical rod 900, so that the optical rod 900 is prone to cracking. The shearing cut 910 of the sheared optical rod 900 will present Figure 3 in the inclined cut 910, which affects the surface quality of the cut optical rod 900.

[0033] The optical rod 900 shearing device provided by the embodiment of the application will be described below in connection with Figures 1-4 .

[0034] Referring to Figure 1 , Figure 2 , the optical rod 900 shearing device provided by the embodiment of the application includes a fiber breaking barrel 100, a shearing knife 200 and a driving assembly.

The shearing knife 200 is arranged in the fiber breaking barrel 100. The driving assembly can drive the shearing knife 200 to move along the axial direction and the radial direction of the fiber inlet hole 121 to shear the optical rod 900.

[0035] By means of the technical solutions in the above embodiment, when the lower end of the optical rod 900 passes through the fiber inlet hole 121 of the fiber breaking barrel 100, the driving assembly drives the shearing cone cutter 200 to move along the axial and radial directions of the fiber inlet hole 121 to shear the optical rod 900 when the fiber head reaches the shearing length. During the downward movement of the optical rod 900, the shearing cone cutter 200 moves along the radial direction of the fiber inlet hole 121 to cut the optical rod 900 transversely; the shearing cone cutter 200 moves along the axial direction of the fiber inlet hole 121 to keep the shearing cone cutter 200 and the optical rod 900 moving synchronously as far as possible, thereby effectively reducing the radial resistance of the shearing cone cutter 200 to the optical rod 900 and reducing the inclination angle of the cut 910 to ensure the surface quality of the cut optical rod 900.

[0036] In some specific embodiments of the present application, the shearing cone cutter 200 includes a cutter handle 210 and a cutter blade 220, the cutter handle 210 is a cylindrical rod, and the cutter blade 220 is a sheet structure, the cutter blade 220 is arranged obliquely downward, and an acute angle is formed between the plane where the cutter blade 220 is located and the axial direction of the fiber inlet hole 121. In this way, the included angle between the cutter blade 220 and the optical rod 900 can be reduced, which can increase the stability of cutting and reduce the generation of cracks caused by vibration of the optical rod 900.

Specifically, the guide sliding ring 400 is a square ring structure. In this way, the cutter handle 210 can only move along the length direction of the guide sliding ring 400 on the support table 300, so that the cutter blade 220 realizes the feeding and retracting actions.

During the downward movement of the optical rod 900, the cutter blade 220 also moves downward, so that the relative axial movement between the cutter blade 220 and the optical rod 900 is small or even no axial relative movement, at this time, the cutter blade 220 cuts the optical rod 900 transversely, and the cut optical rod 900 presents Figure 4The cut 910 (substantially along the radial direction of the light rod 900) can ensure the surface quality of the cut light rod 900. Specifically, the light rod 900 shearing cone device further comprises a protective cover 500, and the driving assembly is arranged in the protective cover 500.

[0039] In some embodiments, the driving assembly further comprises a base 660 located below the pedal 650, and a return spring 670 is arranged between the base 660 and the pedal 650.
