Description

Technical Field

[0001] The utility model relates to the technical field of wire harness detection, in particular to a wire harness measuring and checking tool. Background Art

[0002] Some wiring harnesses include shielding rings and terminals connected to the shielding rings. A positioning hole structure is provided on the terminals. In terms of product size requirements, it is necessary to ensure that the distance from the positioning hole structure on the terminal to one end face of the shielding ring is 54±1mm. Currently, the shielding ring and the terminal connected to the shielding ring are usually placed directly into a gauge of a certain size. If they can be placed in, the product is of qualified size.

[0003] After searching, the Chinese patent announcement number is CN213841924U, which discloses a wire harness measuring and checking fixture. When testing the product, the wire harness measuring and checking fixture provided by the patent will put the shielding ring into the shielding ring positioning mechanism, and then put the terminal into the terminal positioning mechanism. If it can be put in, it is a product with qualified size. Therefore, the utility model can accurately and quickly detect whether the product size is qualified, which not only realizes the detection, but also ensures the speed and accuracy of the detection.

[0004] However, in the above patent, two shielding ring positioning blocks are fixed on a substrate. If the size of the shielding ring is too large, the gap between the shielding ring and the shielding ring positioning block will be too small, making it inconvenient to remove the shielding ring from the positioning groove.

The fixed seat 402 can slightly move left and right in the socket of the slide seat 401, so that products within the tolerance range can be placed in the inspection fixture.

[0028] An adjusting mechanism is arranged in the workbench 1, and the adjusting mechanism is used for driving the two shielding ring positioning blocks 301 to move synchronously in the direction of approaching or moving away from each other. The adjusting mechanism comprises a stepping motor 501 bolted to the rear side of the workbench 1, and the output end of the stepping motor 501 is connected with a bidirectional lead screw 502 through a coupling, and a mounting groove is arranged in the workbench 1, and the bidirectional lead screw 502 is rotatably connected in the mounting groove, and two sliders 503 are threadedly connected on the bidirectional lead screw 502, and the sliders 503 are slidably connected in the mounting groove, and a slide bar 504 is fixedly connected to the top of the slide bar 504, and the shielding ring positioning block 301 is fixedly connected to the top of the slide bar 504, and the stepping motor 501 is started, and the stepping motor 501 drives the bidirectional lead screw 502 to rotate, and the bidirectional lead screw 502 drives the two sliders 503 to move in the direction of moving away from each other, and the slider 503 drives the slide bar 504 to drive the shielding ring positioning block 301 to move in the direction of moving away from each other, thereby increasing the gap between the shielding ring positioning block 301 and the shielding ring, and facilitating the removal of the shielding ring.
