The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-5, an automatic fault stopping device for a large-scale numerical control band sawing machine comprises a base plate 1, a side plate 2 is fixedly installed at the edge of the upper surface of the base plate 1, a supporting leg 3 is fixedly installed at the upper surface of one side of the base plate 1, a cross rod 4 is fixedly installed at the inner wall of the side plate 2, the supporting leg 3 is fixedly installed at the lower surface of the cross rod 4, a hanging plate 5 is fixedly installed at one end of the upper surface of the cross rod 4, a rotating shaft 6 is fixedly installed at the middle part of the hanging plate 5, a rotating wheel 7 is movably connected to the rotating shaft 6, a saw blade 8 is movably connected to the rotating wheel 7, a hollow rotating shaft 9 is movably connected to the middle part of the base plate 1, a first tooth-biting 10 is fixedly installed at the outer side of the hollow rotating shaft 9, a fixed sleeve buckle 11 is fixedly installed at the back of the rotating wheel 7, a first clamping pin, the second card needle 14 is movably connected with the fixed sleeve buckle 11, an arc-shaped block 15 is fixedly mounted at one end of the second card needle 14, and a second engaging tooth 16 is fixedly mounted on one side of the arc-shaped block 15.
Wherein, the telescoping device 13 includes the flexible chamber wall 131, the inside swing joint of flexible chamber wall 131 has the fly leaf 132, one side fixed mounting of fly leaf 132 has first card needle 12, the opposite side fixed mounting of fly leaf 132 has second card needle 14, swing joint has spring 133 between one side of fly leaf 132 and the inner wall of flexible chamber wall 131, can realize through flexible chamber wall 131 when the fracture appears in saw blade 8 or the not hard up condition, can push away second card needle 14 and first card needle 12 to the outside of runner 7 through the effect of spring 133, thereby make second bite 16 and first bite 10 break away from the interlock state, thereby realize runner 7 automatic stop pivoted purpose.
The number of the first clamping needle 12, the telescopic device 13, the second clamping needle 14, the arc-shaped block 15 and the second engaging teeth 16 is two, the automatic stopping devices formed by the structures are arranged into two groups, and the two groups are arranged at two ends of the rotating wheel 7 in central symmetry, so that the second engaging teeth 16 in at least one automatic stopping device are in an engaging state with the first engaging teeth 10, the normal operation of the device is ensured, and if the two automatic stopping devices are separated from the engaging state, the rotating wheel 7 can be automatically stopped.
Wherein, the one end of fixed box 11 and the contact of saw blade 8 is the arc the same with runner 7 outer lane shape, and is not the straight line, can guarantee to have not had the bulge when fixed box 11 stretches out and draws back its end and runner 7's outer lane coincidence to guaranteed can not cause wearing and tearing to saw blade 8 owing to long-time operation, avoided the fracture condition of saw blade 8.
The size of the first tooth 10 is larger than that of the second tooth 16, and the second tooth 16 can be well guaranteed to be compressed on the first tooth 10 through the telescopic device 13 by the first clamping pin 12 through different sizes, so that the second tooth 16 cannot be meshed with the first tooth 10 due to the fact that the second tooth 10 rotates when contacting the first tooth 10 due to overlarge teeth, and the practicability of the device is embodied.
The working principle is as follows: when the saw blade 8 in normal operation is suddenly broken, the movable plate 132 is pushed towards the outer ring direction of the rotating wheel 7 through the spring 133 due to the fact that the pressure of the saw blade 8 on the first clamping pin 12 is suddenly reduced to zero, so that the second clamping pin 14 on the other side is pushed towards the other side, the second engaging teeth 16 on the arc-shaped block 15 are driven to move towards the outer ring direction through the movement of the second clamping pin 14, the second engaging teeth 16 are separated from the first engaging teeth 10, the rotating wheel 7 slowly stops rotating after power is lost, the first clamping pin 12 also moves towards the outer ring of the rotating wheel 7 through the pushing of the movable plate 132 and protrudes out of the rotating wheel 7, and therefore the automatic stopping function of the device is achieved.
