[0046] The support assembly 4 includes a transmission circular plate 41 movably mounted on the top of the base 1 through a support rod 43. The transmission circular plate 41 is provided with a first slot 42 and a through slot 44.

[0047] The fixing assembly 5 includes a support plate 51 mounted in the first slot 42 by bolts. The top ends of the support plate 51 are fixed with limit frames 53. A clamping plate 55 is movably provided between the two limit frames 53.

[0048] A rectangular frame 57 is fixedly mounted on one end of the clamping plate 55. The rectangular frame 57 is sleeved inside the through slot 44. A return spring 56 is provided inside the through slot 44 to support the clamping plate 55 upward. A spring telescopic rod 58 is provided at the bottom of the rectangular frame 57. The stabilizing plate 50 is fixedly mounted on the bottom of the spring telescopic rod 58. A protrusion 59 is fixedly mounted on the top of the stabilizing plate 50.

[0049] The protrusion 59 is in an arc shape. The workpiece is placed between the support plate 51 and the clamping plate 55. The transmission circular plate 41 is rotated to place the workpiece at the bottom of the stamping assembly 3. The transmission frame 8 contacts the protrusion 59 and pulls the clamping plate 55 downward to fix the workpiece.

[0050] A rectangular through slot 54 is formed on the clamping plate 55, and a circular hole is formed in the middle of the support plate 51. The circular hole cooperates with the stamping assembly 3 to realize the stamping of the workpiece;

After the stamping of the workpiece is completed, the transmission circular plate 41 is rotated to rotate the next workpiece to the bottom of the stamping assembly 3 for stamping. The workpiece is continuously stamped in this reciprocating manner. In this process, the workpiece is avoided from being held by hand, which causes the workpiece to be offset during stamping and affects the stamping quality. The safety of the workpiece stamping can be improved.

[0055] like Figure 1 、 Figure 5-Figure 9 As shown, the stabilizing assembly 7 includes a support ring 71 mounted on the bottom of the transmission circular plate 41 through a connecting frame 45. The support ring 71 is provided with a vertical slot 73. A sliding rod 76 is movably sleeved inside the vertical slot 73. A first limiting ring 75 and a second limiting ring 79 are respectively mounted on the upper and lower ends of the sliding rod 76.

[0056] A guide rod 77 is fixed to the outside of the sliding rod 76, and a guide groove for the guide rod 77 to slide vertically is opened on the inner wall of the vertical groove 73;

[0057] A first magnet 74 is fixed to the top of the sliding rod 76, and a second slot 78 is formed in the middle of the sliding rod 76;

[0058] The stabilizing assembly 7 further includes an L-shaped plate 72 fixed to the bottom of the support ring 71 , and a spring 70 is provided between the L-shaped plate 72 and the sliding rod 76 ;

[0059] The sliding rod 76, under the action of the spring 70, makes the first limiting ring 75 contact the top of the support ring 71;

[0060] The clamping assembly 6 includes a fixing frame 61 fixed to the top of the base 1, a clamping block 63 is movably sleeved inside the fixing frame 61, and a spring 62 is provided inside the fixing frame 61 to support the clamping block 63 outwards;

[0061] Under the action of the spring 62, one end of the clamping block 63 contacts the outside of the support ring 71, and the support ring 71 rotates along with the transmission circular plate 41, so that the support ring 71 is engaged with the inside of the second clamping groove 78;

[0062] The punching assembly 3 further includes a docking rod 34 mounted on the punching head 33 via a connecting plate 32 , and the connecting plate 32 and the punching head 33 are detachably connected;

[0063] A second magnet is fixed to the bottom of the docking rod 34, and the docking rod 34 and the first magnet 74 remain coaxial and vertical;

[0064] The punch head 33 moves downward to punch the workpiece, and the second magnet at the bottom of the docking rod 34 contacts the first magnet 74 . The punch head 33 and the docking rod 34 move upward to pull the sliding rod 76 , so that the clamping block 63 is disengaged from the second clamping groove 78 .

[0065] By placing the workpiece on the support plate 51 and rotating the transmission circular plate 41 so that the workpiece is located at the bottom of the stamping assembly 3, the support ring 71 rotates accordingly. When the workpiece is located at the bottom of the stamping assembly 3, the block 63 engages with the inside of the second slot 78 to limit the support ring 71, the transmission circular plate 41 and the workpiece. The punching head 33 moves downward to stamp the workpiece. After the stamping is completed, the second magnet at the bottom of the docking rod 34 contacts and adsorbs the first magnet 74. When the punching head 33 and the docking rod 34 move upward, the sliding rod 76 is driven to move up and stretch the spring 70. During the upward movement of the sliding rod 76, the block 63 gradually disengages from the inside of the second slot 78. At this time, the transmission circular plate 41 and the support ring 71 can rotate, and the block 63 always conflicts with the outside of the support ring 71. When the transmission circular plate 41 rotates, it drives the sliding rod 76 and the first magnet 74 to disengage from the second magnet at the bottom of the docking rod 34, and the next workpiece can be stamped by rotating the transmission circular plate 41.

[0066] The working principle and use process of the present invention:

[0067] The workpiece is placed between the clamping plate 55 and the support plate 51, and the rotating transmission circular plate 41 rotates with the support rod 43 as the central axis, and the workpiece rotates to the bottom of the stamping assembly 3. During the rotation, the transmission frame 8 guides the protrusion 59, so that the protrusion 59 pulls the spring telescopic rod 58, the rectangular frame 57 and the clamping plate 55 to move downward, fixing the workpiece on the top of the support plate 51. At the same time, the support assembly 4 is fixed by the clamping assembly 6 on the stabilizing assembly 7 to ensure the accuracy of the stamping of the workpiece by the stamping assembly 3. The workpiece can be stamped by the stamping assembly 3. After the stamping of the workpiece is completed, the transmission circular plate 41 can be rotated to rotate the next workpiece to the bottom of the stamping assembly 3 for stamping. The workpiece is continuously stamped in this reciprocating manner.

[0068] By rotating the transmission circular plate 41, the workpiece is positioned at the bottom of the stamping assembly 3, and the support ring 71 rotates accordingly. When the workpiece is at the bottom of the stamping assembly 3, the block 63 engages with the inside of the second slot 78 to limit the support ring 71, the transmission circular plate 41 and the workpiece. The punching head 33 moves downward to stamp the workpiece. After the stamping is completed, the second magnet at the bottom of the docking rod 34 contacts and adsorbs the first magnet 74. When the punching head 33 and the docking rod 34 move upward, the sliding rod 76 is driven to move up and stretch the spring 70. During the upward movement of the sliding rod 76, the block 63 gradually disengages from the inside of the second slot 78. At this time, the transmission circular plate 41 and the support ring 71 can rotate, and the block 63 always conflicts with the outside of the support ring 71. When the transmission circular plate 41 rotates, it drives the sliding rod 76 and the first magnet 74 to disengage from the second magnet at the bottom of the docking rod 34, and the next workpiece can be stamped by rotating the transmission circular plate 41.
