Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness testing technology, specifically an automotive wiring harness tensile testing machine. Background Technology

[0002] As a core connection component of the vehicle's electrical system, the connection strength between the terminals and wires of automotive wiring harnesses directly affects vehicle operational safety, and tensile testing is a crucial step in evaluating this performance. Current testing methods require first inserting the wiring harness terminals into the terminal chuck slots of the testing machine, and then fixing the wiring harness body to the clamping assembly.

[0003] Traditional clamping components mostly use bolt locking or manual clamping plate structures. When fixing, the position of the pressure plate needs to be adjusted manually and the bolts tightened. When removing, the operation needs to be reversed, which is cumbersome. Moreover, automotive wiring harnesses are mostly multi-core soft wires with a soft texture. This fixing method is time-consuming and labor-intensive, reducing testing efficiency. Therefore, we need to propose an automotive wiring harness tensile testing machine. Utility Model Content

[0004] The purpose of this utility model is to provide an automotive wiring harness tensile testing machine to solve the problems mentioned in the background art, which require manual adjustment of the pressure plate position and tightening of bolts when fixing automotive wiring harnesses, and require reverse operation when removing them. The steps are cumbersome, and the fixing method is time-consuming and labor-intensive, reducing testing efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automotive wiring harness tensile testing machine includes: a base plate with a bracket fixedly mounted on its top, and a cylinder fixedly mounted on the bracket; a movable seat fixedly mounted on the telescopic end of the cylinder; a support base fixedly mounted on the top of the bracket, and a fixed clamping block fixedly mounted on the top of the support base; a movable clamping block disposed on the top of the support base, with a push rod fixedly connected to the bottom of the movable clamping block for clamping and fixing the automotive wiring harness in conjunction with the fixed clamping block, and a guide frame for positioning the movable clamping block fixedly mounted on the top of the support base; and a movable groove formed on a mounting plate, the mounting plate also having an inclined actuation groove, and the push rod inserted into the movable groove.

[0007] Preferably, the bottom of the movable clamping block contacts the top of the support base, and the side and top of the movable clamping block both contact the inner side of the guide frame.

[0008] Preferably, it also includes a tension sensor, which is fixedly installed on the side of the movable base. A connecting plate is fixedly installed on the tension sensor, and a locking mechanism for locking the end terminals of the wire harness is installed on the connecting plate.

[0009] Preferably, the locking mechanism includes a fixed base and a terminal block holder. The fixed base is fixedly installed on the connecting plate. A T-shaped block is fixedly connected to the bottom of the terminal block holder. A T-shaped groove adapted to the T-shaped block is opened in the fixed base. The T-shaped block is disposed in the T-shaped block. Multiple sets of locking grooves are opened on the terminal block holder.

[0010] Preferably, a first guide rail is fixedly installed on the top of the bracket, and a first slider is fixedly installed on the bottom of the mounting plate, with the first slider slidably mounted on the first guide rail.

[0011] Preferably, a second guide rail is fixedly installed on the top of the base plate, and a second slider is fixedly installed on the bottom of the movable seat, with the second slider slidably mounted on the second guide rail.

[0012] Preferably, both the fixed clamping block and the movable clamping block have multiple sets of protrusions on their sides.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention utilizes a design incorporating a mounting plate, a movable clamping block, a push rod, and a shifting groove. When a cylinder pushes the movable seat to move, the mounting plate moves, and the push rod moves through the shifting groove to the shifting groove. The inclined shifting groove, in conjunction with the push rod's movement of the movable clamping block, brings the movable clamping block close to the fixed clamping block, automatically clamping and fixing the automotive wiring harness. The entire process requires no manual adjustment of the pressure plate or tightening of bolts, completely simplifying the fixing process. Operators only need to place the wiring harness to complete the fixing, significantly reducing operational difficulty. By eliminating the repetitive steps of manual operation, the fixing time for a single test is significantly shortened, improving overall testing efficiency. Attached Figure Description

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution:

[0022] An automotive wiring harness tensile testing machine includes: a base plate 1, on which a bracket 2 is fixedly mounted, and a cylinder 3 is fixedly mounted on the bracket 2; a movable seat 4, fixedly mounted on the telescopic end of the cylinder 3; a support base 13, fixedly mounted on the top of the bracket 2, and a fixed clamping block 14 is fixedly mounted on the top of the support base 13; a movable clamping block 16, located on the top of the support base 13, with a push rod 17 fixedly connected to the bottom of the movable clamping block 16 for clamping and fixing the automotive wiring harness in conjunction with the fixed clamping block 14, and a guide frame 15 for positioning the movable clamping block 16 fixedly mounted on the top of the support base 13; and a movable groove 18, formed on a mounting plate 10, and the mounting plate 10 also has an inclined actuation groove 19, with the push rod 17 inserted into the movable groove 18.

[0023] In an optional embodiment: such as Figure 1 , Figure 2 and Figure 4 As shown, the bottom of the movable clamping block 16 contacts the top of the support base 13, and the side and top of the movable clamping block 16 are in contact with the inner side of the guide frame 15.

[0024] It should be noted that the support base 13 is provided with a clearance groove for the push rod 17 to avoid. The push rod 17 is located in the clearance groove. The push rod 17 contacts the inner side of the guide frame 15 through the clearance groove, the side and top of the moving clamp 16, and the guide frame 15. This guides the moving clamp 16, allowing it to move stably and preventing it from shifting during adjustment, which would affect the clamping of the automotive wiring harness.

[0025] In an optional embodiment: such as Figure 1 As shown, it also includes a tension sensor 5, which is fixedly installed on the side of the movable base 4. A connecting plate 6 is fixedly installed on the tension sensor 5, and a locking mechanism for locking the end terminals of the wire harness is installed on the connecting plate 6.

[0026] It should be noted that the tension sensor 5 is used to measure the tension of the wire harness. A control panel 22 is fixedly installed on the top of the base plate 1. The tension sensor 5 is electrically connected to the control panel 22, and the control panel 22 is electrically connected to the solenoid valve. The solenoid valve is connected to the cylinder 3 through a pneumatic hose. When the control panel 22 issues a command, the solenoid valve coil is energized, the valve core switches, and the direction of compressed air flow is changed, thereby extending or retracting the cylinder 3. The control method of the tension sensor 5 and the cylinder 3 is common knowledge in the field. This part is not the innovation of this utility model. Furthermore, this application document is mainly used to protect the structure and shape and their combination. Therefore, this application document will not explain the control method and circuit connection in detail.

[0027] In an optional embodiment: such as Figures 2 to 3 As shown, the locking mechanism includes a fixed base 7 and a terminal locking base 8. The fixed base 7 is fixedly installed on the connecting plate 6. A T-shaped block is fixedly connected to the bottom of the terminal locking base 8. A T-shaped groove adapted to the T-shaped block is opened in the fixed base 7. The T-shaped block is located in the T-shaped block. Multiple sets of locking slots 9 are opened on the terminal locking base 8.

[0028] It should be noted that the size of the multiple card slots 9 gradually increases from left to right, which can accommodate different automotive wiring harnesses.

[0029] By engaging the T-slot and the T-block, and by sliding the terminal holder 8, the terminal holder 8 can be moved on the fixed seat 7, thereby allowing the corresponding slot 9 to be rotated according to the diameter of the automotive wiring harness, so as to facilitate the tensile test of the automotive wiring harness.

[0030] Additionally, an anti-detachment groove is provided on the side of the terminal holder 8. During the tensile test of the automotive wiring harness, the end terminals of the automotive wiring harness can be locked in the anti-detachment groove to prevent the end terminals of the automotive wiring harness from falling off the terminal holder 8.

[0031] In an optional embodiment: such as Figure 1 As shown, a first guide rail 11 is fixedly installed on the top of the bracket 2, and a first slider 12 is fixedly installed on the bottom of the mounting plate 10. The first slider 12 is slidably installed on the first guide rail 11.

[0032] It should be noted that the first guide rail 11 and the first slider 12 cooperate to support and guide the mounting plate 10, so that when the moving seat 4 moves the mounting plate 10, the mounting plate 10 can move stably on the bracket 2.

[0033] In an optional embodiment: such as Figure 1and Figure 2 As shown, a second guide rail 20 is fixedly installed on the top of the base plate 1, and a second slider 21 is fixedly installed on the bottom of the movable seat 4. The second slider 21 is slidably installed on the second guide rail 20.

[0034] It should be noted that the second guide rail 20 cooperates with the second slider 21 to guide the movable seat 4, so that the movable seat 4 can stably drive the tension sensor 5 to move. Through the tension sensor 5 dragging the slot 9, the tension sensor 5 measures the tension borne by the wire harness and observes the connection between the terminal and the cable.

[0035] In an optional embodiment: such as Figure 2 and Figure 4 As shown, both the fixed clamping block 14 and the movable clamping block 16 have multiple sets of protrusions on their sides.

[0036] It should be noted that, by setting the protrusions, and by cooperating with the fixed clamping block 14 and the movable clamping block 16, when clamping and fixing the automotive wiring harness, the protrusions can squeeze the automotive wiring harness, thereby fixing the automotive wiring harness.

[0037] The usage process of this utility model is as follows: When it is necessary to test the tensile strength of the car wiring harness, place one end of the car wiring harness inside the slot 9, place the terminal of the end of the car wiring harness in the anti-disengagement slot, straighten the car wiring harness, place the car wiring harness on the top of the support base 13, so that the car wiring harness is placed between the fixed clamp 14 and the movable clamp 16, so that the excessively long part of the car wiring harness hangs down on the side of the support base 13.

[0038] The cylinder 3 is activated via the control panel 22. The extension rod of the cylinder 3 pushes the movable seat 4, causing the movable seat 4 to move the tension sensor 5 and the terminal holder 8. The terminal holder 8 drags the automotive wiring harness. As the movable seat 4 moves, it simultaneously moves the mounting plate 10. The push rod 17 moves within the movable groove 18. When the push rod 17 moves into the actuating groove 19, the inclined actuating groove 19 pushes the push rod 17 to slide the movable clamp 16 under the guidance and positioning of the guide frame 15. After the movable clamp 16 approaches the fixed clamp 14, it automatically clamps and fixes the automotive wiring harness between the fixed clamp 14 and the movable clamp 16. After clamping the automotive wiring harness, the movable seat 4 continues to move the terminal holder 8, causing the tension sensor 5 to measure the tension of the wiring harness until the terminal falls off, completing the test. The tension sensor 5 transmits an electrical signal to the control panel 22 via a signal line, so that the measured value is displayed on the control panel 22.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
