For example, they can refer to fixed or detachable connections, or integration; mechanical or electrical connections; direct or indirect connections through an intermediate medium; internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0024] See Figure 1 、 Figure 2 and Figure 3 The automatic feeding device of a metal stamping equipment shown in the figure includes a frame 1, a servo motor 2 is installed inside the frame 1, and a base plate 3 is installed after the output shaft of the servo motor 2 passes through the frame 1. A carrier plate 4 is detachably matched with the base plate 3, and a positioning hole 41 is arranged in a ring on the plate surface of the carrier plate 4, and a positioning rod 31 corresponding to the positioning hole 41 is arranged in a ring on the plate surface of the base plate 3, and a plurality of clamping units 5 are arranged in a ring on the outside of the carrier plate 3.

[0025] In the above technical solution, the frame 1 is installed on the side of the stamping equipment. The rotation of the servo motor 2 can drive the clamping unit 5 to rotate a fixed angle. The servo motor 2 uses a servo reduction motor, which is convenient for more precise control of the rotation amount. The clamping unit 5 is rotated to the stamping workbench. After one stamping, the servo motor 2 drives the carrier plate 4 to rotate a fixed angle, so that the next clamping unit corresponds to the working position of the stamping equipment.

[0026] There are multiple carrier plates 4. When one carrier plate is being punched, the other carrier plates are in a filling state, so as to realize rapid and continuous punching.

[0027] See Figure 4 and Figure 5 As shown, the clamping unit 5 includes a pipe fitting 51, which is installed on the outside of the carrier plate 4 and is located on the diameter line of the carrier plate 4. A nut 52 is rotatably provided at the opening of the pipe fitting 51, and a bearing 53 is fitted between the nut 52 and the pipe fitting 51. A guide block 54 is axially provided at the outer wall of the pipe fitting 51, and a bolt 55 is clearance-fitted in the pipe fitting 51. The bolt 55 has a guide groove 56 that fits the guide block 54. The nut 52 is threadedly fitted with the bolt 55, and a clamping portion 6 is provided at the end of the bolt 55 away from the pipe fitting 51.

[0028] In the above technical solution, the position of the bolt 55 can be adjusted by rotating the nut 52, so that after the clamping portion 6 clamps the plate to be punched, the punched part of the plate can effectively reach the punching area.

[0029] See Figure 4 As shown, the clamping part 6 includes a base plate 61, which is fixed to the bolt 55. A groove 62 is provided on the surface of the base plate 61, and the groove 62 is located on the diameter line of the base plate 61. A mounting hole 63 is radially penetrated at the outer wall of the base plate 61, and the mounting hole 63 and the groove 62 are on the same diameter line. A driving rod 64 is rotatably provided in the mounting hole 63, and a terminal 65 is provided at one end of the driving rod 64. A first bearing 66 is fitted between the driving rod 64 and the mounting hole 63. The driving rod 64 has two threaded portions with opposite rotation directions, and a clamping block 67 is slidably fitted in the groove 62. The threaded portion fits the clamping block 67. When the driving rod 64 rotates, the two clamping blocks 67 are displaced in opposite directions, and a limiting plate 68 is provided at the bottom position of the opposite surfaces of the two clamping blocks 67.

[0030] In the above technical solution, the two clamping blocks 67 are driven to move by the rotation of a single driving rod 64, and the clamping or disassembly of the punched sheet is completed after the movement. The lowering position of the sheet can be limited by the limiting plate 68, and the upper end surface of the limiting plate 68 is consistent with the table height of the stamping workbench.

[0031] See Figure 4 As shown, anti-slip tooth grooves 671 are provided on the opposite surfaces of the two clamping blocks 67.

[0032] The tooth groove 671 can increase the stability after clamping.

[0033] See Figure 3 As shown, a magnet block 331 is embedded in the top of the base plate 3 , and the carrier plate 4 is magnetically attracted to the magnet block 331 .

[0034] The design of the magnet block can achieve the technical effect of magnetically fixing the carrier plate 4.
