[0033] The left rivet assembly 24 includes a left rivet block 24a, which is mounted on the upper mold base 21a; the left rivet assembly 24 also includes a left ejector seat 24b mounted on the lower mold base 21b, and a left ejector 24c mounted on the left ejector seat 24b; one end of the left ejector 24c is mounted on the left ejector seat 24b, and the other end of the left ejector 24c is mounted on the product seat 26, and one end of the left ejector 24c is against the bottom end of the left rivet block 24a. The left rivet assembly 24 also includes a left elastic member (not shown in the figure), one end of the left elastic member is mounted on the product seat 26, and the other end of the left elastic member is mounted on the left ejector pin 24c. The left ejector pin 24c is t ransmittedly mounted on the product seat 26 through the left elastic member; the left ejector pin 24c is provided with a left limiting groove 24d, and the product seat 26 is provided with a left mounting hole 26b. A left limiting column (not shown in the figure) is installed in the left mounting hole 26b. The left limiting column is located in the left limiting groove 24d and is used to limit the movement stroke of the left rivet assembly 24.

[0034] The right rivet assembly 25 includes a right rivet block 25a, which is mounted on the upper mold base 21a; the right rivet assembly 25 also includes a right ejector seat 25b mounted on the lower mold base 21b, and a right ejector 25c mounted on the right ejector seat 25b; one end of the right ejector 25c is mounted on the right ejector seat 25b, and the other end of the right ejector 25c is mounted on the product seat 26, and one end of the right ejector 25c is against the bottom end of the right rivet block 25a.

[0035] like Figures 9 and 10 As shown, the product being riveted (not shown) includes a terminal block 30 with a wire and a housing 40. The housing 40 has a first riveting portion 41, a second riveting portion 42, and a third riveting portion 43 for riveting and fixing. The first riveting portion 41 is located on the second curved surface 23a of the lower rivet cutter 23, the second riveting portion 42 is located on the movement stroke of the left ejector 32, and the third riveting portion 63 is located on the transport stroke of the right ejector 42.

[0036] The working principle of the present invention is as follows: first, the shell 40 with the wire terminal 30 is placed in the product limiting groove 26a for positioning, the first riveting portion 41 of the shell 40 is placed on the second curved surface 23a of the lower rivet cutter 23, and then the driving element 12 is started. The driving element 12 drives the hanging platform 13 to move downward, and the hanging platform 13 drives the hanging platform seat 28 to move. Since the hanging platform seat 28 and the upper mold base 21a are integrated, the upper mold base 21a is driven to operate downward, and the pre-pressing block 27 on the upper mold base 21a first contacts the shell 40 to further fix the shell 40. Then the upper rivet cutter 22 operates downward and cooperates with the lower rivet cutter 23 to rivet the first riveting portion 41 on the wire terminal, thereby fixing the wire terminal 30. At the same time, the left rivet block 24a and the right rivet block 25a operate downward to drive the left ejector 24c and the right ejector 25c to operate, so that the left ejector 24c rivets the second riveting part 42, and the right ejector 25c rivets the third riveting part 43. The riveting will stop for a while, and then the driving element 12 drives the riveting mechanism 20 to operate upward, the upper rivet cutter 22 is separated from the lower rivet cutter 23, and the left ejector 24c and the right ejector 25c are reset due to the action of the left elastic member and the right elastic member respectively. Since the preset length of the bottom end of the pre-pressing block 27 exceeds the preset length of the bottom end of the upper rivet cutter 22, the riveted wire will not separate from the product seat 26 as the upper rivet cutter 22 rises. Finally, the product can be taken out after the pre-pressing block 27 separates from the product. Since the riveting mechanism 20 is installed on the frame 11 by matching the hanging base 28 and the hanging base 13, and then further fixed to the frame 11 by the action of screws, the riveting mechanism 20 can be easily disassembled and assembled on the frame 11. When replacing the riveted product, the riveting mechanism 20 can be removed, and then the upper rivet knife 22, the lower rivet knife 23, the left rivet assembly 24 and the right rivet assembly 25 on the riveting mechanism 20 can be replaced. This structural setting facilitates the replacement of the riveting mechanism 20 and is suitable for riveting a variety of products. At the same time, the products that are easy to disassemble at this time are easy to migrate. Compared with the machines on the market that integrate wires and riveting machines, the power socket provided on the distribution box 14 can avoid the clutter caused by wire entanglement during migration.

[0037] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
