Description
Technical Field
[0001] This utility model relates to the field of automotive wiring harness testing technology, and in particular to an automotive wiring harness testing device. Background Technology
[0002] Automotive wiring harnesses are the core of a vehicle's electrical network; without them, there is no automotive electrical system. A wiring harness is an assembly consisting of copper-formed contact terminals (connectors) crimped to wires and cables, then covered with a molded insulator or an outer metal shell, and bundled together to form a connected circuit. The wiring harness industry chain includes wires and cables, connectors, processing equipment, wiring harness manufacturing, and downstream application industries. Wire harnesses have a wide range of applications, and during wiring harness production, testing devices are needed to inspect them. However, general testing devices have some drawbacks, such as:
[0003] General testing devices cannot effectively test the strength of wire harnesses during use, resulting in poor quality wire harnesses and affecting their later use. Utility Model Content
[0004] The purpose of this invention is to provide an automotive wiring harness testing device to solve the problems mentioned in the background art.
[0005] An automotive wiring harness testing device includes a frame and a hydraulic push rod: a testing mechanism is provided on one side of the frame, and a hydraulic push rod is provided on the other side of the frame; clamping mechanisms are respectively provided on the opposing sides of the hydraulic push rod and the testing mechanism.
[0006] Preferably, the detection mechanism includes a fixed shaft, a support column, and a fixed spring. The fixed shaft is disposed on the inner side of the frame, the support column is slidably disposed inside the fixed shaft, and the fixed spring is sleeved on the outer side of the support column. The fixed spring is located inside the fixed shaft.
[0007] Preferably, the outer side of the support column is marked with graduations.
[0008] Preferably, the outer side of the fixed shaft is threaded with a fixed sleeve, the inner side of the fixed sleeve is in contact with the fixed spring, and the support column passes through the fixed sleeve and is connected to the clamping mechanism.
[0009] When the device is in use, it is connected to the wire harness via the clamping mechanism. The wire harness is then straightened for easy testing. Simultaneously, when testing the strength of the wire harness, the clamping mechanism and the support column are pulled outward at the same time. The side of the support column is marked with a scale. The extension of the fixed spring can be monitored by the length of the support column extending from the fixed sleeve. The extension length of the support column can be accurately and effectively monitored by means of a motion camera installed on the inside of the frame. A shim is installed at the bottom of the fixed shaft to reduce the impact force caused by the support column and improve the buffering effect of the device.
[0010] Since the fixed sleeve and the fixed shaft are connected by threads, the fixed sleeve can be rotated to separate them from the fixed shaft, thereby opening the fixed shaft to inspect and replace the internal support column.
[0011] Preferably, the clamping mechanism is provided in two sets. The clamping mechanism includes a fixed frame, a motor, a lead screw, and a clamping frame. The two fixed frames are respectively arranged on the sides of the support column and the hydraulic push rod. The lower end of the fixed frame is provided with a motor, and the output end of the motor is connected to the lead screw. The lead screw is rotatably arranged inside the fixed frame. The two sides of the lead screw have opposite thread directions. The two sides of the lead screw are threaded to the clamping frame. One side of the clamping frame is connected to the lead screw, and the other side of the clamping frame is penetrated by a positioning post. The positioning post is arranged inside the fixed frame.
[0012] When the device is in use, the motor drives the lead screw to rotate. Since the lead screw and the clamping frame are connected by threads, and the other end of the clamping frame is limited by the positioning post, the clamping frame can be prevented from rotating during use. Thus, when the lead screw rotates, it will drive the clamping frames on both sides to move inward or outward at the same time, thereby achieving the clamping of the wire harness.
[0013] After the wire harness is clamped, the hydraulic push rod will pull the wire harness to straighten it for testing. Due to the buffer of the fixed spring, the wire harness can be prevented from being damaged. When testing the strength of the wire harness, the hydraulic push rod will continuously pull the wire harness until the wire harness breaks.
[0014] Preferably, a buffer pad is provided on the opposite side of the clamping frame.
[0015] The buffer pad allows the clamp to fit better against the wire harness, increasing the clamping force of the device and preventing damage to the wire harness.
[0016] The beneficial effects of this utility model are:
[0017] 1. When the device is in use, the motor drives the lead screw to move the clamping frame, which clamps and fixes the wire harness. Then, the hydraulic push rod is used to straighten the wire harness for easy inspection.
[0018] When it is necessary to test the strength of the wire harness, the hydraulic push rod will pull the wire harness until it breaks. The support column can be monitored by a motion camera to determine the extension length of the support column and the compression of the fixing spring, thereby determining the force when the wire harness breaks.
[0019] When it is necessary to test whether the strength of the wire harness meets the requirements, simply stretch the support post to the fixed elongation. Attached Figure Description

[0025] 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.
[0026] In practical implementation: such as Figure 1-3 As shown, an automotive wiring harness testing device includes a frame 1 and a hydraulic push rod 11: a testing mechanism is provided on one side of the interior of the frame 1, and a hydraulic push rod 11 is provided on the other side of the interior of the frame 1. Clamping mechanisms are respectively provided on the opposing sides of the hydraulic push rod 11 and the testing mechanism.
[0027] The testing mechanism includes a fixed shaft 2, a support column 3, and a fixed spring 4. The fixed shaft 2 is located inside the frame 1. The support column 3 is slidably arranged inside the fixed shaft 2. The fixed spring 4 is sleeved on the outside of the support column 3 and is located inside the fixed shaft 2.
[0028] The outer side of the support column 3 is marked with graduations.
[0029] The outer side of the fixed shaft 2 is threaded with a fixed sleeve 5. The inner side of the fixed sleeve 5 is in contact with the fixed spring 4. The support column 3 passes through the fixed sleeve 5 and is connected to the clamping mechanism.
[0030] When the device is in use, it is connected to the wire harness through the clamping mechanism. The wire harness is then straightened for easy testing. At the same time, when testing the strength of the wire harness, the clamping mechanism and the support column 3 are pulled outward simultaneously. The side of the support column 3 is marked with a scale. The extension of the fixed spring 4 can be monitored by the length of the support column 3 extending from the fixed sleeve 5. The extension length of the support column 3 can be accurately and effectively monitored by means of a motion camera installed on the inside of the frame 1. In addition, a shim is installed at the bottom of the fixed shaft 2. The shim can reduce the impact force caused by the support column 3 and improve the buffering effect of the device.
[0031] Meanwhile, the fixed sleeve 5 and the fixed shaft 2 are connected by threads, so the fixed sleeve 5 can be rotated to separate it from the fixed shaft 2, thereby opening the fixed shaft 2 to inspect and replace the internal support column 3.
[0032] The clamping mechanism is provided in two sets. The clamping mechanism includes a fixed frame 6, a motor 7, a lead screw 8, and a clamping frame 9. The two fixed frames 6 are respectively set on the side of the support column 3 and the hydraulic push rod 11. The motor 7 is set at the lower end of the fixed frame 6. The output end of the motor 7 is connected to the lead screw 8. The lead screw 8 is rotatably set inside the fixed frame 6. The two sides of the lead screw 8 have opposite thread directions. The clamping frame 9 is threaded to both sides of the lead screw 8. One side of the clamping frame 9 is connected to the lead screw 8, and the other side of the clamping frame 9 is penetrated by a positioning post 12. The positioning post 12 is set inside the fixed frame 6.
[0033] When the device is in use, the motor 7 drives the lead screw 8 to rotate. Since the lead screw 8 and the clamping frame 9 are connected by threads, and the other end of the clamping frame 9 is limited by the positioning post 12, the clamping frame 9 can be prevented from rotating during use. Thus, when the lead screw 8 rotates, it will drive the clamping frames 9 on both sides to move inward or outward at the same time, thereby achieving the clamping of the wire harness.
[0034] After the wire harness is clamped, the hydraulic push rod 11 will pull the wire harness to straighten it for testing. Due to the buffering effect of the fixed spring 4, the wire harness can be prevented from being damaged. When testing the strength of the wire harness, the hydraulic push rod 11 will continuously pull the wire harness until the wire harness breaks.
[0035] A buffer pad 10 is provided on the opposite side of the clamping frame 9.
[0036] The buffer pad 10 allows the clamping frame 9 to fit better against the wire harness, increasing the clamping force of the device and preventing damage to the wire harness.
