Therefore, at least two operators are required to perform welding and welding position detection respectively, with relatively low efficiency and numerous processes. Based on this, the utility model proposes a jig mechanism for wire harness welding. This kind of jig mechanism integrates a welding tooling and a wire harness fixing tooling, and can automatically detect the strength of the welding position after welding, without the need to configure an additional detection jig, which improves the efficiency and reduces the labor cost at the same time.

Among them, a track 2 is integrated on the bottom plate 1, the jig bench 3 is installed at the rear side of the bottom plate 1, a handle 4 is installed on the outer side of the jig bench 3, and a cover plate is provided on the top side of the jig bench 3; the welding tooling is installed on the cover plate, and the welding tooling includes an upper air cylinder 5, a top frame 6, a welding cover 7 and a welding head. Among them, the shaft end of the upper air cylinder 5 is connected to the top frame 6, the welding cover 7 is installed inside the top frame 6 through a telescopic rod, a welding head is provided inside the welding cover 7, and the welding cover 7 can move downward with the top frame 6 and approach the wire harness fixing tooling when the upper air cylinder 5 is started; the wire harness fixing tooling includes a lower air cylinder 8, a tooling table 9, elastic guide posts 10, a tooling top plate 11, a test plate 12 and a card slot tooling. Among them, the bottom side of the tooling table 9 can be slidably connected to the track 2 through a slide table.

[0020] In this embodiment, a sensor (not shown in the figure) for detecting whether the wire harness fixing tooling is in place is further provided inside the jig bench 3.

[0021] In this embodiment, the lower air cylinder 8 is fixed on one side of the bottom plate 1 and its piston rod end is connected to the tooling table 9. The lower air cylinder 8 can push the tooling table 9 to move forward along the track 2 and approach the welding tooling.

[0022] In this embodiment, the elastic guide posts 10 are vertically fixed on both sides of the end face of the tooling table 9, and the test plate 12 is fixed on the end face of the tooling table 9 and located between the two elastic guide posts 10.

[0023] In this embodiment, the tooling top plate 11 can be sleeved on the elastic guide posts 10 through a sliding sleeve, and a card slot tooling can be fixed on the tooling top plate 11 through screws. The card slot tooling includes a panel 13 and a card seat module 14.

[0024] In this embodiment, openings corresponding to the test plate 12 are provided in the middle of both the panel 13 and the tooling top plate 11. Two groups of card seat modules 14 are integrated on the panel 13, and each card seat module 14 includes a bottom card seat and a top card seat hinged on the side of the bottom card seat. Card slots for fixing the wire harness are provided on both the bottom card seat and the top card seat; both ends of the bottom side of the top frame 6 are integrally connected with pressing plates 15, and the pressing plates 15 can move downward with the top frame 6 and press against the tooling top plate 11.

[0025] When the tooling is working, the specific process is as follows:

[0026] 1. The equipment is initialized. The tooling table 9 is driven by the lower cylinder 8 to move outward along the track 2 to reset and feed materials.

[0027] 2. The operator places the two wire harnesses to be welded on the bottom card seat of the card seat module 14 respectively, and then rotates the top card seat to press and fix the wire harnesses. At this time, the welding ends of the two wire harnesses are arranged oppositely and close to each other.

[0028] 3. The tooling table 9 is driven by the lower cylinder 8 to move along the track 2 to the position directly below the wire harness fixing tooling. The sensor detects that it is in place, and the lower cylinder 8 is closed. Then, the upper cylinder 5 drives the top frame 6 and the welding cover 7 to move downward.

[0029] 4. The welding cover 7 is further driven to move downward by the telescopic rod to drive the welding head to weld the welding ends of the two wire harnesses. When the welding cover 7 is implemented, it can be equipped with a smoke exhaust or flue gas treatment device to prevent welding fumes from overflowing.

[0030] 5. After the welding is cooled, the telescopic rod drives the welding cover 7 to reset. At this time, the height of the welding cover 7 is lower than the height of the bottom pressing plate 15 of the top frame 6.

[0031] 6. The upper cylinder 5 drives the top frame 6 and the pressing plate 15 to continue moving downward. The pressing plate 15 will press down the tooling top plate 11, causing the tooling top plate 11 to move downward along the elastic guide post 10. At this time, the test plate 12 will pass through the panel 13 and the opening on the tooling top plate 11 and contact the welding ends of the two wire harnesses. The test plate 12 can press against the welding ends with a certain force to detect whether there are welding quality problems at the welding ends.

[0032] It should be noted that: the entire device is controlled by the total control box (which can be installed on the top of the bench during implementation). Since the equipment matched with the control box is a common equipment and belongs to the existing mature technology, the electrical connection relationship and the specific circuit structure are not described in detail here.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
