Description

Technical Field

[0001] This utility model belongs to the field of wire harness testing technology, and in particular relates to a wire harness fixing test structure. Background Technology

[0002] Wire harnesses are the overall system of service equipment for a certain load source group, such as trunk lines, switching devices, and control systems. Wire harnesses play an important role in industry. With the continuous development of wire harnesses and the improvement of product safety, various industries have higher and higher requirements for the quality of wire harnesses. Therefore, testing equipment is used to test wire harnesses.

[0003] The existing wire harness fixing test structure fixes the ends of industrial wire harnesses in four directions using clamping components. By setting up several lifting components that can drive the middle of the industrial wire harness to rise, it can simultaneously perform tensile tests on multiple industrial wire harnesses of different lengths and diameters, which not only improves testing efficiency but also enhances practicality.

[0004] While existing test structures can fix and stretch wire harnesses, their clamping and lifting components use different drive structures, and the clamping components have drive components installed in all four directions. This makes the overall design of the test structure complex and cumbersome, which is not conducive to maintenance and repair, and will increase the additional cost of the test structure.

[0005] Therefore, in view of the above situation, there is an urgent need to develop a wire harness fixing test structure to overcome the shortcomings in current practical applications. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model embodiment is to provide a wire harness fixing test structure to solve the problems in the background technology mentioned above.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A wire harness fixing test structure includes a structural base, wherein sliding grooves are symmetrically formed on both sides of the structural base, and further includes:

[0009] A fixed module includes a moving unit, a rotating unit, a control cylinder, and a guide post. One end of the moving unit is located at the bottom of the structural base, and the other end of the moving unit passes through a sliding groove and is connected to two rotating units and a control cylinder symmetrically arranged on both sides of the structural base. The rotating unit is rotatably mounted on the moving unit. One end of the rotating unit is slidably engaged with the guide post fixed on the structural base, and the other end of the rotating unit is slidably engaged with an eccentric groove distributed circumferentially inside the control cylinder. The control cylinder is fixed on the moving unit.

[0010] A test module is installed in the middle of the structural base and between two rotating units, and a pressure sensor is installed inside the test module;

[0011] The moving unit moves its two rotating units and two control cylinders away from each other by telescopic movement. The rotating units fix the wire harness inside the device circumferentially by moving and sliding with the guide post and eccentric groove, and stretch the two ends of the circumferentially fixed wire harness in the opposite direction. The middle part of the wire harness in the stretched state is located on the test module and squeezes the pressure sensor.

[0012] As a further technical solution of this utility model, the moving unit includes a driving component and an L-shaped block. The driving component is fixed to the bottom of the structural base. The driving component adopts a bidirectional hydraulic telescopic structure. The output ends on both sides of the driving component are fixed with L-shaped blocks. The L-shaped blocks are slidably installed in the slide groove. One end of the L-shaped block extends to the top of the structural base and is equipped with a rotating unit and a control cylinder.

[0013] As a further technical solution of this utility model, the rotating unit includes a rotating cylinder, a support, a spiral block, a fixed block, a V-shaped rod, a telescopic component, and a slider. The rotating cylinder is rotatably mounted on the support, and the support is fixed on the L-shaped block. A spiral block that slides and engages with a guide post is spirally arranged on the outer wall of the rotating cylinder. A fixed block and a V-shaped rod are circumferentially distributed on one side of the rotating cylinder. The V-shaped rod is coaxial with the fixed block, and one end of the V-shaped rod is rotatably connected to the fixed block. A telescopic component is installed on the other end of the V-shaped rod, and a slider that slides and engages with an eccentric groove is fixed on the telescopic component.

[0014] As a further technical solution of this utility model, the telescopic component adopts a telescopic structure composed of a spring and a telescopic rod.

[0015] As a further technical solution of this utility model, the test module includes a fixed base, a support column, a mounting groove, a sliding column, a spring, and an arc-shaped test plate. The fixed base is fixed to the structural base by the support column and is located between two rotating units. The fixed base has a vertically opened mounting groove. A pressure sensor is installed at the bottom of the mounting groove. A sliding column is slidably installed in the mounting groove. A spring is installed between the sliding column and the pressure sensor. One end of the sliding column extends outside the fixed base and is fixedly connected to the arc-shaped test plate. The height of the arc-shaped test plate is higher than the height of the rotating cylinder.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] The two ends of the wire harness are respectively inserted into two rotating units. The moving unit, through telescopic movement, can drive the two rotating units and two control cylinders on it to move away from each other. The rotating units, through movement and sliding cooperation with the guide post and eccentric groove, can not only circumferentially fix the wire harness inside, making it stable within the rotating unit and preventing the wire harness from shifting during the test, thus ensuring the accuracy of the wire harness test data, but also reverse-stretch the two ends of the circumferentially fixed wire harness, so that the middle of the wire harness is located on the test module and squeezes the pressure sensor, thereby completing the tensile strength test of the wire harness. Only one driving element is needed to complete the fixing and stretching of the wire harness, improving the testing efficiency and quality of the test structure, simplifying the test structure, and reducing the cost of the test structure.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] like Figures 1 to 4 As shown, a wire harness fixing test structure provided as an embodiment of this utility model includes a structural base 1, on which sliding grooves 5 are symmetrically opened on both sides, and further includes:

[0027] The fixed module 4 includes a moving unit 41, a rotating unit 42, a control cylinder 43, and a guide post 44. One end of the moving unit 41 is located at the bottom of the structural base 1, and the other end of the moving unit 41 passes through the slide groove 5 and is connected to two rotating units 42 and control cylinders 43 symmetrically arranged on both sides of the structural base 1. The rotating unit 42 is rotatably mounted on the moving unit 41. One end of the rotating unit 42 is slidably engaged with the guide post 44 fixed on the structural base 1, and the other end of the rotating unit 42 is slidably engaged with the eccentric groove 431 distributed circumferentially inside the control cylinder 43. The control cylinder 43 is fixed on the moving unit 41.

[0028] Test module 3 is installed in the middle of the structural base 1 and between two rotating units 42. A pressure sensor 34 is installed inside the test module 3.

[0029] The two ends of the wire harness 2 are respectively inserted into the two rotating units 42. The moving unit 41 can move the two rotating units 42 and the two control cylinders 43 away from each other by telescoping. The rotating unit 42 can not only fix the wire harness 2 circumferentially and stably place it in the rotating unit 42 by moving and sliding with the guide post 44 and the eccentric groove 431, thus preventing the wire harness 2 from shifting during the test and ensuring the accuracy of the test data of the wire harness 2, but also stretch the two ends of the circumferentially fixed wire harness 2 in the opposite direction, so that the middle part of the wire harness 2 is located on the test module 3 and squeezes the pressure sensor 34, thereby completing the tensile strength test of the wire harness 2. The fixing and stretching of the wire harness 2 can be completed with only one driving element, which improves the test efficiency and test quality of the test structure, simplifies the test structure, and reduces the cost of the test structure.

[0030] like Figures 1 to 3 As shown, in a preferred embodiment of the present invention, the moving unit 41 includes a driving component 411 and an L-shaped block 412. The driving component 411 is fixed to the bottom of the structural base 1. The driving component 411 preferably adopts a bidirectional hydraulic telescopic structure. The output ends on both sides of the driving component 411 are fixed with L-shaped blocks 412. The L-shaped blocks 412 are slidably installed in the slide groove 5. One end of the L-shaped blocks 412 extends to the top of the structural base 1 and is equipped with a rotating unit 42 and a control cylinder 43.

[0031] In this embodiment, the driving component 411 can drive the two L-shaped blocks 412 away from each other through bidirectional synchronous extension and retraction. The two L-shaped blocks 412 drive their respective rotating units 42 and control cylinders 43 away from each other. During the movement, the rotating unit 42 slides in cooperation with the guide post 44. The guide post 44 controls the rotating unit 42 to rotate, so that the rotating unit 42 can rotate and move simultaneously, thereby completing the fixing and stretching of the wire harness 2, improving the testing efficiency and quality of the test structure, simplifying the test structure, and reducing the cost of the test structure.

[0032] In a preferred embodiment, the drive component 411 is preferably a telescopic structure consisting of a bidirectional hydraulic telescopic cylinder and a telescopic rod.

[0033] like Figures 1 to 3 As shown, in a preferred embodiment of this utility model, the rotating unit 42 includes a rotating cylinder 421, a bracket 422, a spiral block 423, a fixing block 424, a V-shaped rod 425, a telescopic member 426, and a slider 427. The rotating cylinder 421 is rotatably mounted on the bracket 422, and the bracket 422 is fixed on the L-shaped block 412. The outer wall of the rotating cylinder 421 is spirally provided with a spiral block 423 that slides in cooperation with the guide post 44. The fixing block 424 and the V-shaped rod 425 are circumferentially distributed on one side of the rotating cylinder 421. The V-shaped rod 425 is coaxial with the fixing block 424, and one end of the V-shaped rod 425 is rotatably connected to the fixing block 424. The other end of the V-shaped rod 425 is equipped with a telescopic member 426, and a slider 427 that slides in cooperation with the eccentric groove 431 is fixed on the telescopic member 426.

[0034] like Figures 1 to 3 As shown, in a preferred embodiment of this utility model, the telescopic member 426 preferably adopts a telescopic structure composed of a spring 36 and a telescopic rod, so that the telescopic member 426 has a certain telescopic capacity. This can avoid the fixing block 424 from excessively clamping the wire harness 2, meet the conditions for effectively fixing the thicker wire harness 2, and thus ensure the clamping stability of the wire harness 2. The telescopic member 426 can also adopt a rod-shaped structure without telescopic function, which can facilitate the fixing block 424 to effectively fix the thinner wire harness 2 and improve the applicability of the test structure.

[0035] In this embodiment, the L-shaped block 412 simultaneously drives the rotating cylinder 421, the spiral block 423, the fixed block 424, the V-shaped rod 425, the telescopic member 426, the slider 427, and the control cylinder 43 to move. During the movement, the spiral block 423 can drive the rotating cylinder 421 to rotate by slidingly engaging with the guide post 44. The rotating cylinder 421 simultaneously drives the fixed block 424, the V-shaped rod 425, the telescopic member 426, and the slider 427 to rotate. The slider 427 can drive the V-shaped rod 425 to deflect by rotating and slidingly engaging with the eccentric groove 431. The V-shaped rod 425 drives the fixed block 424 to deflect. The fixed block 424 can complete the circumferential fixation of the wire harness 2 by deflection, so that it is stably placed in the rotating unit 42, avoiding the wire harness 2 from shifting during the test, thereby ensuring the accuracy of the test data of the wire harness 2.

[0036] In a preferred embodiment, the eccentric groove 431 is preferably an arc-shaped groove that is eccentric to the rotating cylinder 421.

[0037] like Figure 2 and Figure 4 As shown, in a preferred embodiment of this utility model, the test module 3 includes a fixed base 31, a support column 32, a mounting groove 33, a sliding column 35, a spring 36, and an arc-shaped test plate 37. The fixed base 31 is fixed to the structural base 1 by the support column 32 and is located between two rotating units 42. The mounting groove 33 is vertically opened in the fixed base 31. A pressure sensor 34 is installed at the bottom of the mounting groove 33. The sliding column 35 is slidably installed in the mounting groove 33. A spring 36 is installed between the sliding column 35 and the pressure sensor 34. One end of the sliding column 35 extends outside the fixed base 31 and is fixedly connected to the arc-shaped test plate 37. The height of the arc-shaped test plate 37 is higher than the height of the rotating cylinder 421.

[0038] In this embodiment, when both ends of the wire harness 2 are stretched, the middle part of the wire harness 2 moves downward and squeezes the arc-shaped test plate 37. The arc-shaped test plate 37 drives the sliding column 35 to move into the mounting groove 33. The sliding column 35 squeezes the pressure sensor 34 through the spring 36. The pressure sensor 34 senses the force generated by the squeezing and transmits the sensing signal to the terminal device, thereby completing the test of the tensile strength of the wire harness 2 and improving the test efficiency and test quality of the test structure.

[0039] In a preferred embodiment, the spring 36 may be retained or removed, depending on the actual testing requirements, but the safety of the pressure sensor 34 and the accuracy of data measurement must be ensured.

[0040] The working principle of this utility model is as follows:

[0041] The driving component 411 can drive the two L-shaped blocks 412 to move away from each other through bidirectional synchronous telescopic extension. The L-shaped blocks 412 simultaneously drive the rotating cylinder 421, the spiral block 423, the fixed block 424, the V-shaped rod 425, the telescopic component 426, the slider 427, and the control cylinder 43 to move. During the movement, the spiral block 423 can drive the rotating cylinder 421 to rotate through sliding engagement with the guide post 44. The rotating cylinder 421 simultaneously drives the fixed block 424, the V-shaped rod 425, the telescopic component 426, and the slider 427 to rotate. The slider 427 can drive the V-shaped rod 425 to deflect through rotation and sliding engagement with the eccentric groove 431. The V-shaped rod 425 drives the fixed block 424 to deflect. The fixed block 424 can complete the circumferential fixation of the wire harness 2 through deflection, so that it is stably placed in the rotating unit 42, preventing the wire harness 2 from shifting during the test, thereby ensuring the accuracy of the test data of the wire harness 2.

[0042] When both ends of the wire harness 2 are stretched, the middle part of the wire harness 2 moves downward and squeezes the arc-shaped test plate 37. The arc-shaped test plate 37 drives the sliding column 35 to move into the mounting groove 33. The sliding column 35 squeezes the pressure sensor 34 through the spring 36. The pressure sensor 34 senses the force generated by the squeeze and transmits the sensing signal to the terminal device, thereby completing the test of the tensile strength of the wire harness 2.

[0043] The above describes the working principle of this wire harness fixing test structure.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
