[0025] like Figure 1 and Figure 2 As shown, the waterproof plug insertion fixture in this embodiment includes:

[0026] Mounting base 1 includes two symmetrically arranged rocker arms 101. Each rocker arm 101 has a rotation center hole 102 and a clearance recess 103 on its upper part. A locking pin is installed through the rotation center hole 102, thus mounting the rocker arm 101 on the machine position. The rotation of the rocker arm 101 refers to its opening and closing. When open, the upper part of the rocker arm 101 moves together, and the clearance recess 103 allows for this movement. The rotation center hole 102 is a countersunk hole. The countersunk hole ensures that the locking pin is located within it, preventing it from protruding from the mounting base 1.

[0027] The mounting base 5 is connected to the mounting base 1. The mounting base 5 is L-shaped and is installed at the bottom of the rocker arm 101 by locking screws. It moves with the rocker arm 101. The mounting base 1 has a recessed platform at its lower part, and one side of the mounting base 5 is installed in the recessed platform. The recessed platform design prevents the connecting section of the mounting base 5 and the locking screws from protruding from the mounting base 1.

[0028] A rubber sheet 3 is mounted on a mounting base 5. The contact edge of the rubber sheet 3 has a C-groove, and two rubber sheets 3 together form an O-shaped hole. The rubber sheet 3 comprises a separate double-layer sheet structure, including an upper rubber sheet 301 and a lower rubber sheet 302. A recessed groove is provided on the mounting base 5, and the rubber sheet 3 is placed within the recessed groove, with its upper surface flush with the upper surface of the mounting base 5.

[0029] A fixing block 4 is provided on the mounting base 5. A limiting piece 51 is provided on the side of the mounting base 5 away from the mounting base 1. An entry groove is provided on the fixing block 4, which is located above the O-hole.

[0030] A limiting pin 6 is provided between the mounting base 1 and the bearing base 5. One end of the limiting pin 6 protrudes from the bearing base 5 and is located on both sides of the fixing block 4.

[0031] Mounting base 1, bearing base 5, and fixing block 4 are made of aluminum alloy, which is wear-resistant and has a long service life.

[0032] In use, the equipment is assembled, and then the mounting base 1 is installed in the designated position using locking pins or bolts, allowing the mounting base 1 to open and close. The upper needle-threading device inserts the waterproof plug and moves downwards, passing through the O-hole. The needle presses down to open the mounting base 1, scraping the waterproof plug during this process to center it. The assembly continues downwards, and then the needle moves upwards to return to its original position, driving the connected guide rail. The guide rail engages with the clearance recess 103, closing the mounting base 1, allowing the assembly of the next workpiece to begin. This utility model's waterproof plug insertion fixture can both center and adjust the waterproof plug, and the use of rubber sheets reduces damage to the plug, effectively lowering the defect rate.
