DETAILED DESCRIPTION

[0019] The following is combined with Figure 1-4 This application is described in further detail.

[0020] The present application discloses a wire cutting machine tool wire breaking prevention device. Figure 1-4A wire cutting machine anti-breaking device comprises two mounting parts 1 symmetrical in upper and lower parts, a filament 2 is mounted between the two mounting parts 1, a fixing frame 3 is fixedly mounted at the bottom of the outer surface of the filament 2 at the bottom end of the mounting part 1, a plurality of first slide grooves 4 are opened on the upper surface of the fixing frame 3, a driven gear ring 5 is rotatably mounted at the bottom end of the inner wall of the fixing frame 3, a driving gear 6 is rotatably mounted near the driven gear ring 5 inside the fixing frame 3, the volume of the driven gear ring 5 is larger than that of the driving gear 6, the driven gear ring 5 and the driving gear 6 are meshed with each other, a driving motor 7 is mounted on the bottom end of the driving gear 6 extending to the outside of the fixing frame 3, a plurality of movable support plates 8 are rotatably mounted on the top edge of the driven gear ring 5, the top end of the movable support plate 8 passes through the first slide groove 4 and a movable frame 11 is welded to the outside, and a friction structure is also arranged inside the movable frame 11.

[0021] By starting the driving motor 7 to drive the active gear 6 to rotate, the active gear 6 drives the driven gear ring 5 to rotate, and drives the movable support plate 8 to rotate. At the same time, the rotating movable support plate 8 drives the movable frame 11 to move along the first slide groove 4 and the second slide groove 10, so that the movable movable frame 11 moves close to the outer surface of the filament 2, reflecting the overall movable adjustment effect of multiple movable frames 11.

[0022] Reference Figure 2 and Figure 4 The friction structure includes a fixed rod 12, which is fixedly mounted at the upper and lower ends of the inner wall of the movable frame 11. A movable block 13 is movably mounted on the outer surface of the fixed rod 12. A through hole is penetrated through the middle of one end of the movable block 13. The outer diameter of the fixed rod 12 is smaller than the inner diameter of the through hole. The fixed rod 12 and the through hole are fitted with each other. One end of the movable block 13 extends to the outside of the movable frame 11 and is welded with an insulating friction block 14. Springs 15 are movably sleeved at the upper and lower ends of the outer surface of the fixed rod 12.

[0023] By making the insulating friction block 14 close to the outer surface of the filament 2, when the filament 2 is pulled by force, the moving filament 2 drives the insulating friction block 14 to move by friction, and then the insulating friction block 14 and the movable block 13 move along the outer surface of the fixed rod 12, so that the movable block 13 pushes the spring 15 to be compressed, and the spring 15 resists and buffers the moving movable block 13, which reflects the supporting effect of the insulating friction block 14 on the filament 2.

[0024] Reference Figure 1 The top of the fixed frame 3 is located on the outer surface of the filament 2 and is fixedly connected to a fixed sleeve 9. A plurality of second slide grooves 10 are provided on the top of the fixed sleeve 9. The top of one side of the movable frame 11 is located inside the second slide groove 10. The second slide groove 10 and the movable frame 11 are coupled with each other. The movable movable frame 11 is supported by the fixed sleeve 9, so that the movable frame 11 can move stably along the first slide groove 4 and the second slide groove 10, which reflects the overall stability of the movable frame 11 during adjustment.

[0025] The implementation principle of the wire cutting machine tool anti-breaking device in the embodiment of the present application is as follows: by starting the driving motor 7 to drive the active gear 6 to rotate, the input end of the driving motor 7 power supply is electrically connected to the output end of the external power supply, so that the active gear 6 drives the driven gear ring 5 to rotate, and drives the movable support plate 8 to rotate, and at the same time, the rotating movable support plate 8 drives the movable frame 11 to move along the first slide groove 4 and the second slide groove 10, so that the movable movable frame 11 drives the insulating friction block 14 to be close to the outer surface of the filament 2. When the filament 2 is pulled by force, the movable filament 2 drives the insulating friction block 14 to move frictionally, and then the insulating friction block 14 and the movable block 13 move along the outer surface of the fixed rod 12, so that the movable block 13 pushes the spring 15 to compress, so that the spring 15 resists and buffers the movable movable block 13; compared with the prior art, this scheme has the effect of facilitating the limiting and fixing of the filament 2 under tension, thereby improving the overall service life of the filament 2 and solving the problem of the filament 2 being broken under tension during use.
