Next, the transfer mechanism 21 moves the latch 81 and the round bar 82 to the drilling device 4 to drill the round bar 82. After the round rod 82 is drilled, the transfer mechanism 21 moves the latch tongue 81 and the round rod 82 to the insertion and striking device 5, the insertion and striking device 5 moves a pin into the first pipe 521 through the first vibrating disc and controls a pin to move into the second pipe 522 in cooperation with the opening and closing mechanism 55, the pin sequentially falls into the pin hole of the latch tongue 81 and the pin hole of the round rod 82 through the fork 54, and then the second punch of the second punching mechanism 53 pushes the pin to move, so that the pin is riveted into the pin hole of the latch tongue 81 and the pin hole of the round rod 82, the latch tongue 81 and the round rod 82 are fixed, and the assembly of the latch tongue assembly 8 is completed.

To sum up, the utility model discloses a structural design to oblique tongue subassembly automatic assembly equipment and the overall arrangement between each device for oblique tongue subassembly automatic assembly equipment can realize riveting the round bar, boring pin nail hole and inserting the automated processing of beating the pin to the oblique tongue subassembly.

Finally, it should be emphasized that the above-described embodiments are merely preferred examples of the present invention, and are not intended to limit the invention, as those skilled in the art will appreciate that various changes and modifications may be made, and any and all modifications, equivalents, and improvements made, while remaining within the spirit and principles of the present invention, are intended to be included within the scope of the present invention.
