[0033] The parts to be processed are transmitted to the lower stamping die seat 5 through the transmission structure of the external device, and the automobile parts are pushed to the middle position of the lower stamping die seat 5 through the fixing mechanism 7, so that the fixing mechanism 7 symmetrically arranged on the lower stamping die seat 5 fixes the parts to be processed to prevent displacement during the stamping process, resulting in low product precision and high product defect rate. When the parts to be processed are pushed to the middle position of the lower stamping die seat 5, the edges of the parts to be processed are clamped by the clamping mechanism 8, and the parts to be processed are further fixed and clamped to avoid displacement during the stamping process and prevent warping during the stamping process. After the parts to be processed are fixed, the hydraulic rod 3 is started, and the hydraulic rod 3 drives the upper stamping die seat 4 to move, so as to stamp the parts to be processed.

[0034] See also Figures 3 to 6 The fixing mechanism 7 includes a first slider 9 slidably connected to the mounting groove 6, a rotating rod 10 passes through the first slider 9, the rotating rod 10 is located in the mounting groove 6, both ends of the rotating rod 10 are rotatably connected to the inner wall of the mounting groove 6, a spiral groove 11 is provided on the rotating rod 10, a first gear ring 12 is rotatably connected to the first slider 9, a first sliding block 13 is fixedly connected to the inner wall of the first gear ring 12, the rotating rod 10 passes through the first gear ring 12, the first sliding block 13 is located in the spiral groove 11, a mounting rod 14 is fixedly connected to the first slider 9, a first sliding groove 15 is provided on the mounting rod 14, a connecting rod 16 is slidably connected to the mounting rod 14 near the first sliding groove 15, and a push plate 17 is fixedly connected to the end of the connecting rod 16 away from the mounting rod 14.

[0036] See also Figure 3 , Figure 4 , Figures 7 to 9The clamping mechanism 8 includes a second slider 18 slidably connected to the first sliding groove 15, and the second slider 18 is fixedly connected to a clamping plate 19 at one end extending outside the first sliding groove 15. The rotating rod 10 in the first sliding groove 15 is connected to a threaded rod 20, and the threaded rod 20 passes through the second slider 18 and is threadedly connected to the second slider 18. The mounting rod 14 is provided with a placement groove 21 at a position below the first sliding groove 15, and the threaded rod 20 extends to one end of the placement groove 21 and is rotatably connected to a first gear 22. The first gear 22 is provided with an annular groove 23, and a first annular block 24 is rotatably connected in the annular groove 23.

A second gear 28 is fixedly connected to the rotating shaft 27, and a clamping assembly 29 is slidably connected to the threaded rod 20 near the clamping groove 25.

[0037] When the part to be processed moves to the middle position of the lower stamping die base 5, the mounting rod 14 moves to enable the locking assembly 29 to connect the first gear 22 and the threaded rod 20, and the motor 41 drives the rotating shaft 27 to rotate, and the rotation of the rotating shaft 27 drives the second gear 28 to rotate, and the rotation of the second gear 28 drives the first gear 22 to rotate, and the rotation of the first gear 22 drives the threaded rod 20 to rotate through the locking assembly 29, and the rotation of the threaded rod 20 drives the second slider 18 to move, and the movement of the second slider 18 drives the clamping plate 19 to move, so that the clamping plate 19 moves quickly to fix the upper surface of the part to be processed, thereby further fixing the part to be processed to prevent the part to be processed from shifting during the stamping process, resulting in low precision of the stamped product and a high product defect rate.

[0038] See also Figure 7 and Figure 8 The engaging assembly 29 includes a second annular block 30 slidably connected to the threaded rod 20 near the card slot 25, the threaded rod 20 is provided with a second sliding slot 31 at a position located in the placement slot 21, a second sliding block 32 is provided on the inner wall of the second annular block 30, a card rod 33 is fixedly connected to the side of the second annular block 30 near the first annular block 24, a third sliding slot 34 is symmetrically provided at a position of the mounting slot 6 near the first sliding slot 15, one end of the third sliding slot 34 near the placement slot 21 is connected to the placement slot 21 through a connecting port, a sliding rod 35 is slidably connected in the third sliding slot 34, a push rod 36 is fixedly connected to one end of the sliding rod 35 near the placement slot 21, the push rod 36 extends to one end in the placement slot 21 and abuts against the second annular block 30, and a first abutting rod 37 is hinged to one end of the sliding rod 35 away from the push rod 36.

[0039] When the pushing plate 17 fixes the workpiece to be processed, the motor 41 will continue to drive the fixing mechanism 7 to move through the transmission structure, and the pushing plate 17 will abut against the workpiece to be processed, thereby driving the first abutting rod 37 to move. The movement of the first abutting rod 37 will push the sliding rod 35 to move, and the movement of the sliding rod 35 drives the pushing rod 36 to move. The movement of the pushing rod 36 drives the second annular block 30 to move, and the movement of the second annular block 30 drives the clamping rod 33 to move, so that the clamping rod 33 moves into the clamping groove 25. Therefore, when the first gear 22 rotates, the first gear 22 can drive the clamping rod 33 to rotate, and the rotation of the clamping rod 33 drives the second annular block 30 to rotate, and the rotation of the second annular block 30 drives the second sliding block 32 to rotate, and the rotation of the second sliding block 32 drives the threaded rod 20 to rotate, thereby fixing the clamping plate 19 to fix the upper surface of the workpiece to be processed.

The second sliding block 32 can enable the second annular block 30 to slide at one end of the threaded rod 20, so that when the clamping rod 33 is engaged with the clamping groove 25, the rotation of the clamping rod 33 can drive the second annular block 30 to rotate through the second sliding block 32.

[0041] See also Figure 8 A first spring 39 is fixedly connected to one side of the second annular block 30, and the other end of the first spring 39 is fixedly connected to the first annular block 24. In the initial state, the second annular block 30 and the first annular block 24 are separated from each other by the action of the first spring 39, so that the clamping rod 33 and the clamping groove 25 are disengaged. When the motor 41 drives the threaded rod 20 to rotate, the clamping plate 19 will not move, and at this time the first annular block 24 rotates in the annular groove 23, and the rotation of the first gear 22 will not drive the threaded rod 20 to rotate through the transmission structure.

[0042] See also Figure 5 The connecting rod 16 is located in the third sliding groove 34, and a pushing opening 40 is opened on the connecting rod 16. The first abutting rod 37 is located in the pushing opening 40. When the connecting rod 16 moves, the first abutting rod 37 will be driven to move through the pushing opening 40, thereby driving the sliding rod 35 to move.

[0043] See also Figure 3 The second gear 28 is meshed with the first gear 22 , and the second gear 28 is meshed with the first gear ring 12 .
