[0027] In specific implementation, the terminal crimping machine is a device that presses and connects the terminal with the end of the wire, which can improve the production efficiency of the wiring harness. When the pressing block 3 is limitedly installed, the conical positioning block 9 on the top of the pressing block 3 is docked with the conical groove at the bottom of the connecting plate 8. The conical structure can facilitate the docking of the two. When the positioning block 9 contacts the inclined surface on one side of the clamping block 10, the clamping block 10 will move. When the clamping block 10 moves, it will squeeze the first spring 11 on one side to make it shrink. When the clamping block 10 contacts the clamping groove inside the positioning block 9, the first spring 11 will reset, pushing the clamping block 10 to move and engage with the positioning block 9, completing the limited installation of the pressing block 3;

[0028] When the pressing block 3 needs to be disassembled, by pressing the two groups of pressing rod bodies 12, the pressing rod body 12 will squeeze the second spring 13 on one side when it moves, causing it to shrink, and the pressing rod body 12 will push the connecting rod 14 to rotate.

When the card block 10 is disengaged from the engagement with the positioning block 9, the pressing block 3 can be moved out. In this way, the above operation can facilitate the auxiliary limiting of the pressing block 3 of the terminal crimping machine, so that the pressing block 3 can be fixed to the terminal crimping machine.

[0029] See also Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 One side of the material box 5 is movably connected with a bidirectional threaded rod 18 through a bearing, and the outer side of the bidirectional threaded rod 18 is threadedly connected with a threaded block 19; one side of the threaded block 19 is movably connected with a connecting rod 20 through a rotating shaft, and one side of the connecting rod 20 is movably connected with a moving rod 21 through a rotating shaft, and a moving plate 22 is welded and fixed to one side of the moving rod 21; a limiting groove matching the moving rod 21 is opened inside the material box 5, and the moving rod 21 is slidably connected to the limiting groove, the bidirectional threaded rod 18 and the threaded block 19 constitute a threaded transmission structure, and the material box 5 and the moving rod 21 constitute a sliding structure.

[0030] In specific implementation, the terminal crimping machine is a device that presses and connects the terminal to the end of the wire, which can improve the production efficiency of the wiring harness. When transporting the terminals of the terminal crimping machine, in order to adapt to the sizes of terminals in different batches, the size of the blanking box 5 needs to be adjusted. The two-way threaded rod 18 and the two groups of threaded blocks 19 are threadedly transmitted by rotating the two-way threaded rod 18. The number of a group of threaded blocks 19 is two. The two threaded blocks 19 will move in relative directions when the two-way threaded rod 18 rotates. Through the movement of the two groups of threaded blocks 19, the two groups of connecting rods 20 can also rotate. The connecting rod 20 can drive the moving plate 22 to move inside the blanking box 5 through the moving rod 21, so that the space inside the blanking box 5 changes to adapt to terminals of different sizes. In this way, the above operation can facilitate the adjustment of the size inside the blanking box 5 to adapt to terminals of different sizes.

[0031] To sum up: when using a terminal crimping machine that is easy to assist in limiting, first the terminals are unloaded through the unloading box 5. When the terminals move to the opening on one side of the unloading box 5, the electric push rod 6 will push a group of terminals through the opening and move them to the fixed block 4. At this time, the wires can be inserted into the terminals in the fixed block 4, and then the hydraulic rod 2 is started to drive the pressing block 3 to move downward.
