Description

Technical Field

[0001] The present invention relates to the technical field, and in particular to a terminal crimping auxiliary wire threading device for a new energy charging gun. Background Art

[0002] The connection between the charging gun terminal and the cable is mostly hexagonal crimping. There are two main production methods in the industry. The first is manual operation, which usually involves manually inserting the stripped cable into the terminal tail, and then manually inserting it into the press mold to start crimping to achieve the connection of the terminal cable. Manual threading is inefficient and can easily cause wire breakage, affecting product quality.

[0003] The second method uses equipment for automatic threading and crimping. Automatic threading and crimping uses tapered hole to guide the threading. During the threading process, high requirements are placed on the state of the cable after stripping. If the wire is slightly larger, it is not easy for the cable to be fully threaded into the hole at the tail of the terminal, which affects the quality of the terminal crimping and makes the product quality uneven.

[0004] To this end, a new energy charging gun terminal crimping auxiliary wire threading device is proposed. Summary of the invention

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] Embodiment 1:

[0024] See also Figure 1-2 , the present invention provides a technical solution:

[0025] A new energy charging gun terminal crimping auxiliary harness threading device, comprising a pressing cylinder 1, a harness mechanism, and a lifting cylinder 13. The harness mechanism is composed of an upper harness block 2, a left cylinder 6, a left harness block 8, a right harness block 9, a right cylinder 11, a limit bolt 12, and a guide rod 14;

[0026] The output end of the left cylinder 6 is connected to the left harness block 8, and the output end of the right cylinder 11 is connected to the right harness block 9, which can drive the two harness blocks (left harness block 8, right harness block 9) to clamp the cable 4. At the same time, the output end of the downward pressure cylinder 1 is connected to the upper harness block 2, and the upper harness block 2 descends to the gap formed by the closure of the left harness block 8 and the right harness block 9, so that the left harness block 8 and the right harness block 9 clamp the terminal 3, and the output end of the lifting cylinder 13 is connected to the wiring harness mechanism, wherein the wiring harness mechanism includes a left bracket 5, a mounting base plate 7, and a right bracket 10. The left bracket 5 and the right bracket 10 are respectively installed on the surface of the mounting base plate 7. The output end of the lifting cylinder 13 is connected to the mounting base plate 7, the left cylinder 6 is installed on the left bracket 5, and the right cylinder 11 is installed on the right bracket 10. The left cylinder 6 and the right cylinder 11 are both provided with guide rods 14, and the two are connected to the left harness block 8 and the right harness block 9 through the guide rods 14.

[0027] Working principle:

[0028] When the device is placed in conjunction with the servo wire feeding mechanism, it can realize the fully automatic threading and crimping process of the terminal. The wire feeding mechanism is composed of an upper wire harness block 2, a left bracket 5, a left cylinder 6, a mounting base 7, a left wire harness block 8, a right wire harness block 9, a right bracket 10, a right cylinder 11, a limit bolt 12 and a guide rod 14. In the initial state, the left wire harness block 8 and the right wire harness block 9 are in a retracted state driven by the left cylinder 6 and the right cylinder 11. At this time, the wire harness port is in an open state, and the two cylinders, the pressing cylinder 1 and the lifting cylinder 13, are in a retracted state. When the cable 4 is delivered to the top of the wire harness port, the lifting cylinder 13 drives Figure 2 The whole mechanism is pushed upward, so that the stripped part of the cable is in the cable harness opening. The left cylinder 6 and the right cylinder 11 are ventilated to push the left harness block 8 and the right harness block 9 to clamp the cable 4, and the exposed copper wires of the cable 4 after stripping are gathered to the center. Then the cylinder 1 is pressed down to ventilate to drive the upper harness block 2 to descend. The harness block 2 descends into the gap formed by the closure of the left harness block 8 and the right harness block 9, and presses down against the inner wall of the left harness block 8 and the right harness block 9 to gather the copper wires scattered up and down to the middle. The cable is slightly withdrawn to straighten the wire head, and the cable harness arrangement is completed.

[0029] The cable 4 is fed forward, and the copper wire of the half-length exposed part is guided through the cable hole and inserted into the hole at the tail of the terminal. Then, the left cable block 8 and the right cable block 9 are retracted under the drive of the left cylinder 6 and the right cylinder 11, and the lower pressure cylinder 1 is ventilated to drive the upper cable block 2 to rise, and the lifting cylinder 13 drives the upper cable block 2 to rise. Figure 2 The entire mechanism retracts downward, opening the entire cable bundling mechanism, and the cable 4 moves forward to insert all the exposed copper wires into the tail hole of the terminal. At this point, the mechanism completes the entire cable bundling and threading action.
