[0027] like Figures 1 to 6 As shown, the utility model provides a mechanical automatic cutting device, comprising:

[0028] A base 1, a fixing frame 2 is fixedly installed on the upper surface of the base 1, a limit rod 3 is movably sleeved on the bottom of the right surface of the fixing frame 2, the left end of the limit rod 3 penetrates the fixing frame 2 and extends to the inside of the fixing frame 2 and is fixedly installed with a rectangular block 4;

[0029] A long groove 5, which is provided in the middle of the top of the base 1;

[0030] A driving mechanism, the driving mechanism is arranged inside the long slot 5;

[0031] Among them, the driving mechanism includes a No. 1 motor 6, which is fixedly installed on the left side of the inner surface of the long slot 5. The other end of the output shaft of the No. 1 motor 6 is fixedly sleeved with a rotating shaft 7. The right end of the rotating shaft 7 extends to the right end of the inner surface of the long slot 5. The outer surface of the rotating shaft 7 is fixedly sleeved with a gear 8. The upper end of the outer surface of the gear 8 is meshed with a tooth plate 9. The tooth plate 9 is fixedly connected to the bottom end of the rectangular block 4. The rotation of the rotating shaft 7 and the gear 8 drives the tooth plate 9 to move to the left.

[0032] When motor No. 1 6 is running, shaft 7 drives gear 8 to rotate, and the outer surface of gear 8 will be meshed with the bottom of tooth plate 9, so that tooth plate 9 and rectangular block 4 move to the left, so as to facilitate the subsequent truncation of different parts of the mechanical parts.

[0033] A pneumatic cylinder 10 is fixedly installed in the middle of the top of the fixing frame 2 , and a connecting plate 11 is fixedly installed at the bottom end of the pneumatic cylinder 10 which penetrates the fixing frame 2 and extends to the inside of the fixing frame 2 .

[0034] When the pneumatic cylinder 10 is running, the connecting plate 11 will move up and down.

[0035] A second motor 12 is fixedly mounted on the right side of the inner surface of the connecting plate 11 , a round shaft 13 is fixedly sleeved on the other end of the output shaft of the second motor 12 , and a cutting blade 14 is fixedly connected to the left end of the round shaft 13 .

[0036] When the second motor 12 is running, the circular shaft 13 will drive the cutting blade 14 to rotate.

[0037] Among them, a threaded rod 15 is threadedly sleeved in the middle of the top of the rectangular block 4, and the bottom end of the threaded rod 15 passes through the rectangular block 4 and extends to the inside of the rectangular block 4 and is movably connected to a fixed block 16, which is movably connected to the inside of the rectangular block 4.

[0038] The threaded rod 15 is rotated to drive the fixing block 16 to clamp and fix the mechanical parts placed inside the rectangular block 4 .

[0039] Among them, a No. 3 motor 17 located on the right side of the back side of the fixing frame 2 is fixedly installed on the upper surface of the base 1, a long shaft 18 is fixedly sleeved on the other end of the output shaft of the No. 3 motor 17, a winding wheel 19 is fixedly sleeved on the outer surface of the long shaft 18, a connecting rope 20 is fixedly connected to the middle part of the outer surface of the winding wheel 19, the other end of the connecting rope 20 is fixedly connected to a baffle 21, and the bottom of the baffle 21 is movably connected to the top of the base 1.

[0040] When the third motor 17 is running, the long shaft 18 drives the winding wheel 19 to rotate, so that the outer surface of the winding wheel 19 can continuously wind the connecting rope 20, so that the connecting rope 20 pulls the baffle 21 to move to the right.

[0041] Among them, limiting grooves 22 are opened on the front and rear sides of the upper surface of the base 1, the left end of the limiting groove 22 is located at the bottom end of the baffle 21, the internal movably connected limiting block 23 of the limiting groove 22, the top end of the limiting block 23 is fixedly installed on the bottom end of the baffle 21, and the top of the base 1 is fixedly installed with a positioning block 24 located on the right side of the limiting groove 22.

[0042] When the baffle 21 moves to the right, the limit block 23 will move to the right inside the limit groove 22. When the baffle 21 moves to the left end of the positioning block 24, the baffle 21 will stop moving, thereby blocking the baffle 21, thereby ensuring that the cutting blade 14 is located directly above the inside of the baffle 21.

[0043] A notch 25 is formed at the bottom of the left side of the fixing frame 2 , a spring 26 is fixedly connected to the left end of the notch 25 , and a right end of the spring 26 is fixedly connected to the left side of the baffle 21 .

[0045] The working principle and use process of this utility model:

[0046] First, the operator inserts the mechanical parts to be processed from the bottom of the right side of the fixing frame 2 into the interior of the rectangular block 4, and then rotates the threaded rod 15 to make the fixing block 16 move downward inside the rectangular block 4, so that the mechanical parts can be clamped and fixed. Then the operator starts the No. 3 motor 17 to make the long shaft 18 drive the winding wheel 19 to rotate. The outer surface of the winding wheel 19 will continuously wrap around the connecting rope 20, so that the connecting rope 20 has a pulling effect on the baffle 21, so that the baffle 21 drives the limit block 23 to move to the right inside the limit groove 22, and when it moves to the left end of the positioning block 24, it stops moving, and at this time the inside of the baffle 21 is located directly below the cutting blade 14.

[0047] Then, the operator starts the No. 1 motor 6, so that the rotating shaft 7 drives the gear 8 to rotate, thereby driving the toothed plate 9 to move to the left, and then the rectangular block 4 and the mechanical parts move to the left, and then the pneumatic cylinder 10 and the No. 2 motor 12 are started, the connecting plate 11 will move downward, and the circular shaft 13 will cause the cutting blade 14 to rotate, and then the cutting blade 14 will enter the interior of the baffle 21 to cut the mechanical parts. Due to the design of the baffle 21, sparks and debris are effectively prevented from flying, which provides good protection for the operator.
