A plurality of first rivet through holes 62a are arranged on the limiting block 61 and communicated with the limiting groove 62, and the plurality of first rivet through holes 62a are always one-to-one corresponding to the plurality of riveting channels 32a in the upper and lower directions.

[0040] A translation plate 63 is slidingly arranged on the connecting plate 31, and the translation plate 63 is inserted into the limiting groove 62. The width of the limiting groove 62 is greater than the width of the translation plate 63. A plurality of second rivet through holes 63a are arranged on the translation plate 63, and the plurality of second rivet through holes 63a can be one-to-one corresponding to the plurality of riveting channels 32a in the upper and lower directions.

[0041] A translation cylinder 64 is fixed on the upper end surface of the connecting plate 31, and drives the translation plate 63 to move back and forth in the limiting groove 62, so as to block or communicate the first rivet through hole 62a and the riveting channel 32a.

[0042] The working principle of the embodiment is that when the flat valve plate jig is moved to between the riveting pipe 32 and the positioning needle 51, the positioning cylinder 52 drives the positioning needle 51 to ascend, and the positioning needle 51 is inserted into two groups of corresponding riveting holes 16 on the flat valve plate assembly (valve plate 11, valve piece 12, limiting piece 13) from the middle part of the flat valve plate jig, so that the flat valve plate assembly is precisely positioned, and after precise positioning, the positioning cylinder 52 drives the positioning needle 51 to descend and reset; then, the riveting cylinder 33 drives the connecting plate 31 to descend, and during the descending process of the connecting plate 31, when the jaw hole 46 moves to the maximum outer diameter formed by the pair of jaws 41, the inner wall of the jaw hole 46 forces the pair of jaws 41 to move towards each other, and the pair of rivet grooves 43 always clamps the rivet 15 at the lower end of the riveting pipe 32; until the connecting plate 31 descends and the two rivet channels 32a are aligned with the two groups of riveting holes 16, then the jaw cylinder 44 drives the sliding plate 45 to ascend until the jaw hole 46 moves to the minimum outer diameter formed by the pair of jaws 41, the pair of jaws 41 is reset by elasticity, the pair of jaws 41 moves reversely, the pair of rivet grooves 43 releases the rivet 15 at the lower end of the riveting pipe 32, and the two rivets 15 respectively fall into the two groups of riveting holes 16, so that the positioning and feeding of the rivet are completed.
