[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 This utility model provides a technical solution: a depth difference detection component, including a test component 1. The test component 1 is further provided with a translational push cylinder 3 connected to it for driving its translation. The test component 1 includes a test guide sleeve 10 and a push rod 11 that is limited and slidably engaged with one end of the test guide sleeve 10. The test component 1 also includes a slider 12 connected to the push rod 11. A magnetic scale 13 is correspondingly provided above the slider 12. The test component 1 includes a first sliding seat 14 connected to the drive end of the translational push cylinder 3. The first sliding seat 14 is provided with a first slide rail 15 connected to it. The test component 1 includes a second sliding seat 16 that is limited and slidably engaged with the first slide rail 15. The second sliding seat 16 is connected to the test guide sleeve 10. The test component 1 includes a second slide rail 17 connected to the second sliding seat 16. The second slide rail 17 is limited and slidably engaged with the slider 12. The magnetic scale 13 is located above the second sliding seat 16. When it is necessary to test the depth difference of the wire harness end, the translational push cylinder 3 pushes the first sliding seat 14 forward. This causes all the structures mounted on the first sliding seat 14 to slide synchronously, thereby inserting the wire harness end into the test guide sleeve 10. When the wire harness end is inserted into the test guide sleeve 10, since the probe is compressible inside the wire harness end, the wire harness end begins to push the test guide sleeve 10. At this time, because the push rod 11 abuts against the probe, the push rod 11 will compress the probe inside the wire harness end. Since the diameter of the wire harness end is larger than the aperture of the end of the test guide sleeve 10, when the end of the wire harness end and the end of the test guide sleeve 10... Upon contact, the wire harness end pushes the test guide sleeve 10, thereby causing the second sliding seat 16 to slide on the first slide rail 15. Meanwhile, the push rod 11 drives the slider 12 to slide on the second slide rail 17. Since the push rod 11 is inserted into the inside of the wire harness end, the distance that the push rod 11 drives the slider 12 to slide is the depth difference of the wire harness end. By using the magnetic scale 13 to calculate the sliding distance of the slider 12, the depth difference inside the wire harness end can be obtained. Compared with the prior art, the present invention has a smaller test error and higher test accuracy.

[0020] Test assembly 1 includes a drive cylinder 18 connected to a first sliding seat 14. The drive end of the drive cylinder 18 is provided with a first connecting rod 180 connected thereto. One end of the first connecting rod 180 is provided with a push seat 19 that slides thereto. The slider 12 is connected to the push seat 19. A first spring 181 is sleeved on the first connecting rod 180. The two ends of the first spring 181 abut against the drive end of the drive cylinder 18 and the push seat 19, respectively. The slider 12 drives the push seat 19 to slide, thereby compressing the first spring 181. After the test is completed, the first spring 181 rebounds and can drive the push seat 19 and the slider 12 to reset.

[0021] The first sliding seat 14 is provided with a second connecting rod 140 that is limited and slidably engaged with it. One end of the second connecting rod 140 is connected to the second sliding seat 16. The second connecting rod 140 is fitted with a second spring 141. The two ends of the second spring 141 abut against the first sliding seat 14 and the second sliding seat 16 respectively. When the first sliding seat 14 slides on the first slide rail 15 and compresses the second spring 141, the second spring 141 rebounds after the test and can drive the first sliding seat 14 to reset.

[0022] To adjust the horizontal height of test component 1, test component 1 is equipped with a lifting drive device 2 that is driven to move it up and down. A translation push cylinder 3 is equipped with a lifting plate 20 connected to it. The lifting plate 20 is equipped with a third slide rail 21 connected to it. The first sliding seat 14 and the third slide rail 21 are in a limiting sliding fit. The lifting drive device 2 includes a transmission screw 23 that is driven to move the lifting plate 20. One end of the transmission screw 23 is equipped with a servo motor 24 that is driven to move it up and down. The lifting plate 20 is equipped with a longitudinal slide rail 25 that is in a limiting sliding fit. By causing the servo motor 24 to drive the transmission screw 23 to rotate, the lifting plate 20 can be driven to move up and down along the transmission screw 23, thereby driving the test component 1 on the lifting plate 20 to move up and down synchronously to adjust the horizontal height.

[0023] A limiting screw 22 is also provided on one side of the lifting plate 20. The limiting screw 22 is set corresponding to the first sliding seat 14. By providing the limiting screw 22, the maximum sliding distance of the translation push cylinder 3 driving the first sliding seat 14 can be limited.

[0024] To improve testing efficiency, the test component 1 is equipped with several units on the lifting plate 20.

[0025] The working principle of this utility model is as follows: When it is necessary to test the depth difference of the wire harness end, the wire harness end is inserted into the test guide sleeve 10. At this time, the probe inside the end pushes the push rod 11 to drive the slider 12 to slide. By using the magnetic scale 13 to calculate the sliding distance of the slider 12, the depth difference value inside the wire harness end can be obtained. Compared with the prior art, this utility model has a smaller test error and higher test accuracy.
