Technical Field

[0001] This application relates to the technical field of automotive wire harness detection, and specifically relates to a combined wire harness detection bench for new energy vehicles. Background Art

[0002] The combined wire harness of new energy vehicles is a very important component in new energy vehicles, responsible for transmitting electrical energy and signals to ensure the normal operation of each vehicle system. After production, it is necessary to conduct tensile tests on it. If the wire harness falls off from the terminal, it indicates that the test is unqualified, and there is a risk of falling off during actual use, affecting the normal use of new energy vehicles.

[0003] Application No. 202122160065.0 discloses a combined wire harness detection device for energy vehicles, including a detection bench, a tensile rod, a moving block, a mold cavity, a pulling rod, etc. The lower clamping seat and the upper clamping seat are used to clamp the wire harness by pressing, and at the same time, different mold cavities are provided on one side of the terminal, and the upper clamping plate is used to clamp the terminal by pressing. Therefore, the clamping and loosening of this application are relatively convenient and fast.

[0004] However, in use, it has the following defects:

[0005] Although the upper and lower clamping seats are used to clamp the wire harness, the lengths and thicknesses of the wire harnesses are different, which may result in the inability to uniformly clamp all wire harnesses, and the sizes of the mold cavities on one side of the terminal are relatively fixed, unable to adapt to various different-sized terminals for clamping, affecting the practicability. Utility Model Content

[0006] The purpose of this application is to provide a combined wire harness detection bench for new energy vehicles, which solves the problems raised in the background art that although the upper and lower clamping seats are used to clamp the wire harness, the lengths and thicknesses of the wire harnesses are different, which may result in the inability to uniformly clamp all wire harnesses, and the sizes of the mold cavities on one side of the terminal are relatively fixed, unable to adapt to various different-sized terminals for clamping, affecting the practicability.

[0007] To achieve the above object, the present application provides the following technical solutions: A combined wire harness detection platform for new energy vehicles, including a detection platform main body, a limit block, a support plate and a turntable. A strip-shaped groove is opened on the right side of the top of the detection platform main body. A lead screw is fixedly installed inside the strip-shaped groove, and a threaded block is threadedly connected to the surface of the lead screw. The top of the threaded block is fixedly connected to the support plate. Clamping grooves are opened on the top surface of the support plate, and telescopic grooves are opened on the left and right inner side walls of the clamping grooves. A telescopic clamping block is horizontally slidably connected inside the telescopic grooves, and a spring is fixedly installed inside the telescopic grooves. The other end of the spring is fixedly connected to the telescopic clamping block. A limit groove is opened on the side wall of the support plate, and the limit groove communicates with the clamping groove. The limit block is horizontally slidably connected inside the limit groove, and the limit block is fixedly connected to the side wall of the telescopic clamping block.

[0008] In this technical solution, through the support plate, the telescopic clamping plate and the cover plate, terminals of various sizes and shapes can be clamped. Press the telescopic clamping block into the telescopic groove, then place the terminal into the clamping groove. After releasing the telescopic clamping block, the telescopic clamping block will slide out of the telescopic groove under the action of the spring, thereby clamping the terminal. Then, clamp the cover plate from above. The soft pad can protect and buffer the terminal at the top, improving the adaptability of the device. At the same time, through the turntable, the pressure plate, the fixing holes and the fixing rods, the wire harness can be fixed. Wind the wire harness directly around the threaded column, and then rotate the pressure plate to move it downward, thereby pressing the wire harness tightly. At this time, slide the slider so that the fixing rod on the side wall of the slider extends into the fixing hole to fix the turntable. In this way, each cable in the wire harness can generate friction due to winding and will not slide easily, improving the fixing effect of the wire harness of the device. After the fixing is completed, the motor is powered on and starts to drive the lead screw to rotate, so that the threaded block drives the support rod to move to the right, thereby completing the tensile test of the wire harness.

[0009] As an optional solution of the technical solution of the present application, a turntable is movably installed on the left side of the top of the detection platform main body. A threaded column is fixedly installed at the center of the top of the turntable, and a pressure plate is threadedly connected to the side wall of the threaded column.

[0010] As an optional solution of the technical solution of the present application, a number of fixing holes are opened in a circle on the side wall of the turntable, and a sliding groove is opened on the top of the detection platform main body on one side of the turntable. A slider is horizontally slidably connected to the surface of the sliding groove, and a fixing rod is fixedly connected to the surface of the slider facing the turntable.

[0011] As an optional solution of the technical solution of the present application, a fixing bolt is threadedly connected to the top of the slider.

[0012] As an optional solution of the technical solution of the present application, a cover plate is hingedly connected to the top edge of the support plate, and a soft pad is fixedly installed at the bottom of the cover plate.

[0013] As an alternative solution of the technical solution of this application, a motor is fixedly installed on the right side wall of the main body of the inspection table, and the tail end of the transmission shaft of the motor is fixedly connected to the right end of the lead screw.

[0014] Compared with the prior art, the beneficial effects of this application are as follows:

[0015] 1. In this application, through the support plate, the telescopic clamping plate and the cover plate, terminals of various sizes and shapes can be clamped. Press the telescopic clamping block into the telescopic groove, then put the terminal into the clamping groove. After releasing the telescopic clamping block, the telescopic clamping block will slide out of the telescopic groove under the action of the spring, thereby clamping the terminal. Then, clamp the cover plate from above. The soft pad can protect and buffer the terminal at the top, improving the adaptability of the device.

[0016] 2. In this application, through the turntable, the pressure plate, the fixing holes and the fixing rods, the wire harness can be fixed. Wind the wire harness directly around the threaded post, and then rotate the pressure plate to move it downward, thereby pressing the wire harness tightly. At this time, slide the slider so that the fixing rod on the side wall of the slider extends into the fixing hole to fix the turntable. In this way, each cable in the wire harness can generate friction due to winding and will not slide easily, improving the fixing effect of the wire harness of the device.

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the following will be further described in conjunction with specific embodiments.

[0023] As Figure 1 shown, a combined wire harness detection platform for new energy vehicles includes a detection platform main body 1, a limit block 8, a support plate 6 and a turntable 13. A strip-shaped groove 2 is opened on the right side of the top end of the detection platform main body 1. A lead screw 4 is fixedly installed inside the strip-shaped groove 2. A motor 3 is fixedly installed on the right side wall of the detection platform main body 1. The tail end of the transmission shaft of the motor 3 is fixedly connected to the right end of the lead screw 4. After the motor 3 is connected to an external power supply and starts, it drives the lead screw 4 to rotate.

[0024] As Figure 1 shown, a turntable 13 is movably installed on the left side of the top end of the detection platform main body 1. A threaded column 14 is fixedly installed in the center of the top end of the turntable 13. And a pressure plate 15 is threadedly connected to the side wall of the threaded column 14. A number of fixing holes 131 are opened in a circle on the side wall of the turntable 13. The pressure plate 15 can squeeze the wire harness wound around the threaded column 14.

[0025] As Figure 1 shown, a chute 16 is opened on the top end of the detection platform main body 1 on one side of the turntable 13. A slider 17 is horizontally slidably connected to the surface of the chute 16. And a fixing rod 19 is fixedly connected to the surface of the slider 17 facing the turntable 13. A fixing bolt 18 is threadedly connected to the top end of the slider 17. The top edge of the support plate 6 is hinged to a cover plate 11. And a soft pad 12 is fixedly installed at the bottom of the cover plate 11. The soft pad 12 can adapt to the protruding part of the terminal and ensure that it will not fly out of the clamping groove 9 during the tensile test.

[0026] As Figure 2 and Figure 3 shown, a threaded block 5 is threadedly connected to the surface of the lead screw 4. The top end of the threaded block 5 is fixedly connected to the support plate 6. A clamping groove 9 is opened on the top surface of the support plate 6. And telescopic grooves 101 are opened on the left and right inner side walls of the clamping groove 9. A telescopic clamping block 10 is horizontally slidably connected to the inside of the telescopic groove 101. And a spring 102 is fixedly installed inside the telescopic groove 101. The other end of the spring 102 is fixedly connected to the telescopic clamping block 10. The spring 102 is always in a compressed state, so that the telescopic clamping block 10 moves towards the center of the support plate 6.

[0027] As Figure 2 shown, a limit groove 7 is opened on the side wall of the support plate 6. And the limit groove 7 communicates with the clamping groove 9. The limit block 8 is horizontally slidably connected to the inside of the limit groove 7. And the limit block 8 is fixedly connected to the side wall of the telescopic clamping block 10.

[0028] During actual use, through the support plate 6, the telescopic clamping plate, and the cover plate 11, terminals of various sizes and shapes can be clamped. Press the telescopic clamping block 10 into the telescopic groove 101, then place the terminal into the clamping groove 9. After releasing the telescopic clamping block 10, the telescopic clamping block 10 will slide out of the telescopic groove 101 under the action of the spring 102, thereby clamping the terminal. Then, clamp the cover plate 11 from above. The soft pad 12 can protect and buffer the terminal at the top, improving the adaptability of the device. At the same time, through the turntable 13, the pressure plate 15, the fixing hole 131, and the fixing rod 19, the wire harness can be fixed. Directly wind the wire harness around the threaded column 14, and then rotate the pressure plate 15 to make it move downward, thereby pressing the wire harness tightly. At this time, slide the slider 17 so that the fixing rod 19 on the side wall of the slider 17 extends into the fixing hole 131 to fix the turntable 13. In this way, each cable in the wire harness can generate friction due to winding and will not slide easily, improving the fixing effect of the wire harness of the device. After the fixing is completed, the motor 3 is powered on and starts to drive the lead screw 4 to rotate, so that the threaded block 5 drives the support rod to move to the right, thereby completing the tensile test of the wire harness.
