[0034] When the operator twists the twisting block 5, since the screw 4 is threadedly connected to the moving block 6, the twisting block 5 will drive the moving block 6 to move through the screw 4. At this time, the moving block 6 will move downward under the limit of the first limit block 3. At this time, the moving block 6 will drive the two moving rods 8 to move through the two moving shafts 7. Then the other ends of the two moving rods 8 will push the round rod 9 to the two gear rods 10. At this time, the two gear rods 10 will move forward under the limit inside the lifting block 1. When the two gear rods 10 release the contact with the square block 11 during the forward movement, the two gear rods 10 will release the locking effect on the square block 11 and the punch 12 as a whole, so that the punch 12 can be easily replaced.

[0035] Among them, movable blocks 13 are fixedly installed on the top of the left and right sides of the lifting block 1, the outer surface of the movable block 13 is movably connected to the second limit block 14, the outer surface of the second limit block 14 is fixedly installed with a fixed plate 15, the top of the fixed plate 15 is fixedly installed with a fixed box 16, and the right side of the fixed box 16 is fixedly installed with a protective shell 17.

[0036] Due to the design of the two second limiting blocks 14 , the movement of the two movable blocks 13 is limited, so that the lifting block 1 can only drive the two movable blocks 13 to move up and down.

[0037] A movable rod 18 is movably sleeved on the outer surface of the top end of the lifting block 1 , and a rotating rod 19 is fixedly sleeved on the inner portion of the top end of the movable rod 18 .

[0038] When the rotating rod 19 rotates, it will drive the movable rod 18 to move. At this time, the bottom end of the movable rod 18 will squeeze the top end of the lifting block 1, causing the lifting block 1 to move downward as a whole.

[0039] Among them, the left and right ends of the rotating rod 19 are movably connected with rotating blocks 20, and there are two rotating blocks 20. The insides of the two rotating blocks 20 are respectively fixedly connected with the first rotating shaft 21 and the second rotating shaft 22, and the other ends of the first rotating shaft 21 and the second rotating shaft 22 are respectively movably connected to the insides of the left and right ends of the fixed box 16.

[0040] Due to the design of the rotating rod 19, the two rotating blocks 20 will be connected. When the second rotating shaft 22 rotates, the second rotating shaft 22 will drive the two rotating blocks 20 to rotate simultaneously through the rotating rod 19. At the same time, the first rotating shaft 21 will rotate under the drive of the rotating block 20. Due to the design of the first rotating shaft 21, the rotating block 20 will be more stable when rotating.

[0041] The other end of the second rotating shaft 22 is fixedly sleeved with a driven gear 23 , and the outer surface of the driven gear 23 is meshedly connected with a driving gear 26 .

[0042] Since the driving gear 26 is meshed with the driven gear 23 , when the driving gear 26 rotates, it drives the driven gear 23 to rotate, and at this time, the driven gear 23 drives the second rotating shaft 22 to rotate.

[0043] A drive motor 24 is fixedly installed at the rear of the left side of the fixed box 16 , and a long shaft 25 is fixedly sleeved on the other end of the output shaft of the drive motor 24 , and the right end of the long shaft 25 is fixedly sleeved on the inside of the drive gear 26 .

[0044] When the driving motor 24 is running, the long shaft 25 will drive the driving gear 26 to rotate.

[0045] Among them, a base 27 is fixedly installed at the bottom end of the front of the fixed plate 15, and a working platform 28 is fixedly installed at the top of the base 27. The back of the working platform 28 is fixedly connected to the front of the fixed plate 15, and a limiting groove 29 is provided at the top of the working platform 28.

[0046] Due to the design of the limiting groove 29, the object located therein will be limited.

[0047] A power motor 30 is fixedly mounted on the bottom end of the working platform 28 , and a rotating shaft 31 is fixedly sleeved on the other end of the output shaft of the power motor 30 .

[0048] When the power motor 30 is running, the rotating shaft 31 will rotate.

[0049] A circular plate 32 is fixedly sleeved on the outer surface of the rotating shaft 31 , and the outer surface of the circular plate 32 is movably connected to the interior of the working platform 28 .

[0050] When the rotating shaft 31 rotates, the circular plate 32 will rotate driven by the rotating shaft 31 .

[0051] The circular plate 32 is movably connected to an extrusion shaft 33 , and a clamping block 34 is fixedly mounted on the top end of the extrusion shaft 33 . The outer surface of the clamping block 34 is movably connected to the inside of the limiting groove 29 .

[0052] When the circular plate 32 rotates, its interior will simultaneously squeeze the outer surfaces of the four extrusion shafts 33, thereby causing the four extrusion shafts 33 to move. At this time, the four clamping blocks 34 will move under the drive of the four extrusion shafts 33. Due to the limitation of the four limiting grooves 29, the four clamping blocks 34 will move inward at this time, and then the four clamping blocks 34 will center and fix the casting during the inward movement.

[0053] The working principle and use process of this utility model:

[0054] First, the operator places the casting on the top of the working platform 28, and then the operator starts the power motor 30. At this time, the rotating shaft 31 will drive the circular plate 32 to rotate. At this time, the inside of the circular plate 32 will squeeze the outer surface of the four extrusion shafts 33 at the same time during rotation, so that the four extrusion shafts 33 drive the four clamping blocks 34 to move. Due to the design of the four limiting grooves 29, the movement of the four clamping blocks 34 will be limited. At this time, the four clamping blocks 34 will move inward along the inside of the four limiting grooves 29 under the drive of the four extrusion shafts 33. Then, the four clamping blocks 34 will clamp the casting at the top of the working platform 28 during the inward movement, thereby realizing the function of automatically centering and fixing the casting. Then the operator starts the driving motor 24. At this time, the long shaft 25 will drive the driving gear 26 to rotate. Since the outer surface of the driving gear 26 is meshed with the outer surface of the driven gear 23, when the driving gear 26 rotates, it will drive the second rotating shaft 2 through the driven gear 23. 2 rotates. Due to the design of the rotating rod 19, the second rotating shaft 22 will drive the two rotating blocks 20 to rotate through the rotating rod 19. At the same time, the first rotating shaft 21 will rotate under the drive of the rotating block 20. Due to the design of the first rotating shaft 21, the overall rotation of the rotating block 20 will be more stable. When the rotating rod 19 rotates, it will drive the movable rod 18 to move. At this time, the bottom end of the movable rod 18 will push the top of the lifting block 1, and the lifting block 1 will drive the two movable blocks 13 to move as a whole. Due to the design of the two second limiting blocks 14, the movement of the two movable blocks 13 will be limited. At this time, the two movable blocks 13 will move downward along the inside of the second limiting block 14 under the drive of the lifting block 1. At this time, the lifting block 1 will drive the punch 12 to move downward as a whole to punch the casting.

[0055] When the operator needs to replace the punch 12, the operator twists the twisting block 5, and the screw 4 will rotate under the drive of the twisting block 5. Since the outer surface of the screw 4 is sleeved with the internal thread of the moving block 6, when the screw 4 rotates, it will drive the moving block 6 to move. Due to the internal design of the first limit block 3, the movement of the moving block 6 will be limited so that it can only move up and down. At this time, the moving block 6 will move downward along the inside of the first limit block 3 driven by the screw 4. At this time, the two moving shafts 7 will move downward under the drive of the moving block 6. When the two moving shafts 7 move downward, they will respectively drive the two moving rods 8 to move. At this time, the two The bottom end of the moving rod 8 will move the round rod 9. At this time, the round rod 9 will push the two gear rods 10 at the same time, so that the two gear rods 10 move forward along the inside of the lifting block 1. Then the two gear rods 10 will release the contact with the square block 11 during the forward movement. At this time, the two gear rods 10 will release the obstruction to the movement of the square block 11, and then cancel the locking effect on the punch 12. Due to the design of the magnet 2, the punch 12 as a whole will not fall under the influence of gravity at this time. Then the operator pulls the punch 12 to separate the punch 12 and the square block 11 as a whole from the lifting block 1, and then places the punch 12 to be replaced, thereby realizing the function of convenient replacement of the punch 12.
