[0027] Figure 2 It is a schematic diagram of the structure of the template in the embodiment of the present invention.

[0028] The high-voltage wire harness includes a wire harness body, a terminal and a connector. The terminal and the connector are respectively arranged at both ends of the high-voltage wire harness.

[0029] Figure 3 Schematic diagram of the structure of the press-in structure in the embodiment of the present invention.

[0030] like Figure 3 As shown, the pressing structure 30 includes a guide rail 31, a slider 32 and a pressure block assembly 33. The guide rail 31 is arranged on the template 10, the slider 32 is slidably arranged on the guide rail 31, and the pressure block assembly 33 is arranged on the slider 32. The two guide rails 31 are arranged parallel to each other and are respectively located on both sides of the detection slot 20, so that the pressure block assembly 33 can slide along the guide rail 31.

[0031] The pressing block assembly 33 includes a connecting rod 331, a movable rod 332 and a pressing block 333. The end of the connecting rod 331 is connected to the slider 32, and the two ends of the connecting rod 331 are respectively connected to the two sliders 32 on the two guide rails 31, so that the connecting rod 331 can be slidably set on the two guide rails 31. The connecting rod 331 and the guide rails 31 are perpendicular to each other, so that the connecting rod 331 can slide along the guide rails 31. A movable groove 3311 is provided on the connecting rod 331, and the movable groove 3311 is a waist-shaped groove. The movable rod 332 can be movably arranged in the movable groove 3311, so that the movable rod 332 can move in a direction perpendicular to the guide rail 31, and the pressure block 333 is arranged on the movable rod 332 at one end close to the detection groove 20. The size of the pressure block 333 is adapted to the size of the wiring harness body detection groove 21. The pressure block 333 is cylindrical, and the outer peripheral surface of the pressure block 333 abuts against the inner wall of the wiring harness body detection groove 21, so that when the connecting rod 331 slides along the guide rail 31, the pressure head 333 can slide along the inner wall of the wiring harness body detection groove 21. During this process, the movable rod 332 can adaptively slide in the movable groove 3311 according to the path of the pressure head 333, so that the pressure head 333 can slide smoothly along the inner wall of the wiring harness body detection groove 21, and effectively press the wiring harness body of the high-voltage wiring harness into the wiring harness body detection groove 21.

[0032] like Figure 1 As shown, two groups of pressing block assemblies 33 are arranged on the guide rail 31 , which can facilitate the quality inspector to press the wire harness body into the wire harness body detection groove 21 .

[0033] A sliding sleeve 334 is provided between the movable groove 3311 and the movable rod 332. The sliding sleeve 334 is sleeved on the movable rod 332, reducing the friction between the movable rod 332 and the movable groove 3311, so that the movable rod 332 slides more smoothly and steadily in the movable groove 3311. The sliding sleeve 334 and the movable rod 332 are connected by a clearance fit, so that the movable rod 332 can rotate in the movable sleeve 334 and can also slide along the movable groove 3311, so that the pressure head 333 can slide more smoothly and steadily along the inner wall of the wire harness body detection groove 21. Limiting flanges 3341 are provided at both ends of the sliding sleeve 334, and the limiting flanges 3341 abut against the connecting rod 331, so as to prevent the sliding sleeve 334 from slipping out of the movable groove 3311, thereby improving the reliability of the structure.

[0034] A counterweight block 335 is provided at the other end of the movable rod 332 away from the pressure block 333. The counterweight block 335 can press the pressure head 333 against the surface of the harness body, thereby effectively pressing the harness body of the high-voltage harness into the harness body detection groove 21 to ensure the reliability of the detection process.

[0035] Figure 4 Schematic diagram of the structure of the clamping assembly in an embodiment of the present invention.

[0036] like Figure 4 As shown, the high-voltage wire harness detection device provided by the present invention also includes a clamping assembly 40, which includes a fixed rod 41, a flip rod 42 and a pressure head 43. A section of the fixed rod 41 is arranged on the template 10, and one end of the flip rod 42 is rotatably connected to the fixed rod 42 by a hinged manner. The pressure head 43 is arranged at the other end of the flip rod, and the pressure head 43 abuts against the harness body of the high-voltage wire harness. The clamping assembly 40 is arranged between two groups of pressing structures 30, and the pressure head 43 abuts against the middle part of the harness body to clamp and fix the middle part of the harness body. The pressing structure 30 moves from the middle part of the harness body to the two ends of the harness body, thereby improving the detection efficiency.

[0037] The clamping assembly 40 also includes a locking rod 44, one end of which is arranged on the template 10, and the other end of the locking rod 33 is provided with a first locking hole 441, and the flip rod 42 is provided with a second locking hole 421 adapted to the first locking hole 441, and locking pins are passed through the first locking hole 441 and the second locking hole 421, so as to fix the locking rod 44 and the flip rod 42, thereby ensuring that the pressure head 43 can clamp and fix the wiring harness body, preventing the wiring harness body from moving or loosening during the detection process, affecting the detection results, and improving the accuracy of the detection results.

[0038] The present invention also provides a high-voltage wire harness detection method, which can detect the angular size of the high-voltage wire harness through the high-voltage wire harness detection device provided by the present invention, comprising the following steps:

[0039] Step S1, the press-in structure 30 is reset, and the two sets of press-in structures 30 are moved to the two ends of the guide rail 31 respectively to provide space for the initial placement of the high-voltage wiring harness.

[0040] Step S2, initially place the high-voltage wire harness in the detection slot 20, fix the middle of the wire harness body by the pressing head 43 of the clamping assembly 40, lift the pressing block 333 and move the pressing structure 30, and move the two sets of pressing structures 30 to the two ends of the clamping assembly 40.

[0041] Step S3, move the pressing structure 30, press the high-voltage wire harness into the detection groove 20, and the quality inspector holds the movable rod 332 and moves the two movable rods 332 toward the two ends of the wire harness body, so as to press the wire harness body of the high-voltage wire harness into the wire harness body detection groove 21, and the pressing blocks 333 on both sides stay at the two ends of the wire harness body. The quality inspector then manually presses the terminal, connector and mounting bracket into the terminal detection groove 22, connector detection groove 23 and mounting bracket detection groove 24 respectively. If it cannot be pressed into the terminal detection groove 22, connector detection groove 23 and mounting bracket detection groove 24, the angle dimension of the high-voltage wire harness is unqualified.

[0042] Step S4, re-inspection of the plug gauge. If the terminals, connectors and mounting brackets in step S3 can be pressed into the terminal detection groove 22, connector detection groove 23 and mounting bracket detection groove 24, then use a 0.1mm plug gauge to detect the gap between the wiring harness body and the inner wall of the wiring harness body detection groove 23. If the 0.1mm plug gauge cannot be inserted and the wiring harness body itself is not warped, the angle dimension is qualified, which further improves the accuracy of the test results.

[0043] Functions and Effects of the Embodiments

[0044] The high-voltage wire harness detection device provided by the present invention includes a template 10, on which is provided a detection groove 20 adapted to the high-voltage wire harness, the detection groove 20 is opened according to the standard size of the high-voltage wire harness, and the template 10 is also provided with a pressing structure 30, which can press the high-voltage wire harness into the detection groove. After the high-voltage wire harness is pressed into the detection groove, the state of the high-voltage wire harness in the detection groove is observed to directly judge whether the angle dimension is qualified, thereby improving the detection efficiency of the angle dimension of the high-voltage wire harness and reducing the workload of quality inspectors.

[0045] The pressing structure 30 is reset, and the two groups of pressing structures 30 are moved to the two ends of the guide rail 31 respectively to provide space for the initial placement of the high-voltage wire harness. The high-voltage wire harness is initially placed in the detection groove 20, the middle of the wire harness body is fixed by the pressure head 43 of the clamping assembly 40, the pressure block 333 is lifted and the pressing structure 30 is moved, and the two groups of pressing structures 30 are moved to the two ends of the clamping assembly 40. The pressing structure 30 is moved to press the high-voltage wire harness into the detection groove 20, and the quality inspector holds the movable rod 332 and moves the two movable rods 332 to the two ends of the wire harness body, thereby pressing the wire harness body of the high-voltage wire harness into the wire harness body detection groove 21, and the pressure blocks 333 on both sides stay at the two ends of the wire harness body. The quality inspector then manually presses the terminal, connector and mounting bracket into the terminal detection groove 22, connector detection groove 23 and mounting bracket detection groove 24 respectively. If they cannot be pressed into the terminal detection groove 22, connector detection groove 23 and mounting bracket detection groove 24, the angle dimension of the high-voltage wire harness is unqualified. The plug gauge is re-inspected. If the terminal, connector and mounting bracket can be pressed into the terminal detection groove 22, connector detection groove 23 and mounting bracket detection groove 24 in step S3, the gap between the wire harness body and the inner wall of the wire harness body detection groove 23 is then detected by a 0.1mm plug gauge. If the 0.1mm plug gauge cannot be inserted and the wire harness body itself is not warped, the angle dimension is qualified, which further improves the accuracy of the test results.
