Description

Technical Field

[0001] The utility model relates to the technical field of wire harness production detection, in particular to a tension detection device for wire harness production. Background Art

[0002] A wiring harness is the overall set of equipment that serves a specific group of load sources, such as trunk lines, switching devices, and control systems. Traffic theory fundamentally studies the relationship between traffic volume, call loss, and wiring harness capacity. Therefore, the wiring harness is a crucial concept in traffic theory. After production, wiring harnesses often undergo various tests, including tensile testing, which often requires the use of a testing machine.

[0003] A Chinese patent application CN202021665721.1 discloses a tensile testing device for wire harness production testing. The key points of its technical solution are: the utility model arranges two symmetrical superimposed protective covers inside the upper end of the slider slot under the tensile measuring slide. The two superimposed protective covers can be stretched and superimposed back and forth as the tensile measuring slide is tested. The semicircular arc structure of the superimposed protective cover can push fallen foreign objects to both sides along the arched arc surface, thereby preventing them from falling into the slider slot and being difficult to remove. The outer end of the superimposed protective cover is sleeved in the folding cover. Since the folding cover has a similar structure to the superimposed protective cover, the superimposed protective cover can be fixed and stored by the folding cover, thereby realizing the extension and contraction of the superimposed protective cover.

[0004] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when the staff needs to test a large number of wire harnesses, the wire harnesses are clamped too firmly or even stuck, causing the staff to use tools or violently dismantle them to replace the old wire harnesses, thereby affecting the staff's work efficiency and possibly causing damage to the detection machine itself; therefore, in response to the above problems, a tensile testing device for wire harness production is proposed.

[0028] Reference Figure 1 As shown, the utility model provides a technical solution: a tension testing device for wire harness production, comprising a testing machine body 1, a dynamometer 2 is installed on the surface of the testing machine body 1, a sliding table 3 is installed in the testing machine body 1, a sliding groove is opened on one side of the testing machine body 1, and a replacement device 4 is provided on the inner surface of the sliding groove of the testing machine body 1. By providing the replacement device 4, the effect of quickly releasing the clamping and replacing the wire harness is achieved, avoiding the situation where the wire harness is clamped too firmly or even stuck when the staff needs to test a large number of wire harnesses, causing the staff to have to use tools or violent disassembly to replace the old wire harness, thereby affecting the work efficiency of the staff and possibly causing damage to the testing machine body 1, thereby improving the use of the device, and a protective device 5 is provided on one side of the testing machine body 1. By providing the protective device 5, the surface buttons of the dynamometer 2 are dust-proof, avoiding dust falling on the surface of the dynamometer 2 when the testing machine body 1 is idle for a long time, causing dust to enter the gap of the buttons on the surface of the dynamometer 2, thereby causing the buttons of the dynamometer 2 to malfunction, thereby improving the protection of the device.

[0029] The specific settings and functions of the replacement device 4 and the protective device 5 are described in detail below.

[0030] Reference Figure 2 and Figure 3As shown, in this embodiment: the replacement device 4 includes a square plate 401, the square plate 401 is slidably connected to the inner surface of the sliding groove of the detection machine body 1, a sliding block 402 is slidably inserted in the square plate 401, and a clamping block 403 is fixedly connected to one side of the sliding block 402. The clamping block 403 is slidably connected to the surface of the sliding table 3, and a support plate 404 is fixedly connected to the upper surface of the square plate 401. A driving rod 405 is inserted into the inner thread of the support plate 404. One end of the driving rod 405 is rotatably connected to a connecting block 406, which abuts against the surface of the sliding block 402. A positioning rod 407 is fixedly connected to the side of the connecting block 406 close to the driving rod 405. The positioning rod 40 The arc surface of 7 is slidably connected to the support plate 404. When the staff rotates the driving rod 405, the driving rod 405 moves in the internal thread of the support plate 404. At the same time, the driving rod 405 drives the connecting block 406 to move, and the connecting block 406 drives the positioning rod 407 to slide in the support plate 404. At this time, the positioning rod 407 has the effect of limiting the connection block 406 to follow the rotation of the driving rod 405, so as to increase the stability of the connecting block 406 when it abuts against the surface of the sliding block 402. The side of the clamping block 403 away from the sliding block 402 is fixedly connected with an anti-skid pad 408. The anti-skid pad 408 is slidably connected to the surface of the sliding table 3. When the staff pushes the sliding block 402, the sliding block 402 The sliding block 402 slides in the square plate 401, and the sliding block 402 drives the clamping block 403 to move. The clamping block 403 drives the anti-skid pad 408 to slide on the surface of the sliding table 3 until the anti-skid pad 408 is clamped with the wiring harness. At this time, the anti-skid pad 408 achieves an anti-skid effect, preventing the wiring harness from sliding off from the clamping of the sliding table 3 and the clamping block 403, thereby affecting the test results. The sliding block 402 is fixedly connected to a strip plate 409 on the side away from the clamping block 403. A sliding rod 410 is slidably inserted in the strip plate 409. One end of the sliding rod 410 is fixedly connected to the square plate 401. The arc surface of the sliding rod 410 is covered with a first spring 411. The two ends of the first spring 411 are respectively connected to the The square plate 401 and the strip plate 409 are fixedly connected. When the staff releases the limit of the connecting block 406 on the sliding block 402, the rebound force of the first spring 411 drives the strip plate 409 to slide on the arc surface of the slide rod 410. At the same time, the strip plate 409 drives the sliding block 402 to slide in the square plate 401. At the same time, the sliding block 402 drives the clamping block 403 to move, and the clamping block 403 drives the anti-slip pad 408 to slide on the surface of the sliding table 3 until the anti-slip pad 408 releases the clamping of the wire harness. At this time, the first spring 411 achieves the effect of automatically releasing the clamping of the anti-slip pad 408 on the wire harness, so as to reduce the staff's operating steps for the device and improve the staff's work efficiency.

[0031] Reference Figure 4As shown, specifically, the protective device 5 includes a fixed rod 51, which is fixedly connected to one side of the detection machine body 1, and an operating plate 52 is slidably connected to the circular arc surface of the fixed rod 51. The operating plate 52 is fixedly connected to the side of the detection machine body 1 close to the detection machine body 1. Two protective grooves are provided on the side of the detection machine body 1 close to the dynamometer 2. The inner surfaces of the two protective grooves of the detection machine body 1 are slidably connected to a protective cover 54. A slot is provided on one side of the protective cover 54. The end of the fixed rod 51 away from the detection machine body 1 is fixedly connected to a limit plate 55. The size of the plugging rod 53 is adapted to the size of the slot of the protective cover 54. When the staff pulls the operating plate 52, the operating plate 52 slides on the circular arc surface of the fixed rod 51. At this time, the limit plate 55 achieves the effect of limiting the maximum sliding distance of the operating panel 52 on the arc surface of the fixed rod 51, avoiding the situation that the operating panel 52 is separated from the arc surface of the fixed rod 51 due to excessive pulling force when the staff pulls the operating panel 52. The arc surface of the fixed rod 51 is sleeved with a second spring 56, and the two ends of the second spring 56 are fixedly connected to the operating panel 52 and the detection machine body 1 respectively. When the staff releases the operating panel 52, the rebound force of the second spring 56 drives the operating panel 52 to slide on the arc surface of the fixed rod 51. At the same time, the operating panel 52 drives the insertion rod 53 to move until the insertion rod 53 is inserted into the slot of the protective cover 54. At this time, the second spring 56 improves the stability of the insertion rod 53 when limiting the protective cover 54.

[0032] Working principle: when the staff needs to replace the detection harness, they rotate the driving rod 405, and the driving rod 405 moves in the inner thread of the support plate 404. At the same time, the driving rod 405 drives the connecting block 406 to move, and the connecting block 406 drives the positioning rod 407 to slide in the support plate 404 until the connecting block 406 no longer abuts the surface of the sliding block 402. At this time, the rebound force of the first spring 411 drives the strip plate 409 to slide on the arc surface of the sliding rod 410. At the same time, the strip plate 409 drives the sliding block 402 to slide in the square plate 401. At the same time, the sliding block 402 drives the clamping block 403 to move, and the clamping block 403 drives the anti-slip pad 408 to slide on the surface of the sliding table 3 until the anti-slip pad 408 releases the clamping of the harness. At this time, one end of the new harness is placed on the surface of the sliding table 3, and the other end is fixed on the dynamometer 2. At this time, the strip plate 409 is pushed, and the strip plate 4 09 slides on the arc surface of the slide rod 410, the first spring 411 is compressed, and at the same time the strip plate 409 drives the sliding block 402 to slide in the square plate 401, and at the same time the sliding block 402 drives the clamping block 403 to move, and the clamping block 403 drives the anti-slip pad 408 to slide on the surface of the sliding table 3 until the anti-slip pad 408 clamps the new wiring harness. At this time, the sliding table 3 is pulled, and the sliding table 3 drives the new wiring harness to gradually straighten, and the data is displayed on the dynamometer 2. At this time, the effect of quickly releasing the clamping and replacing the wiring harness is achieved, avoiding the situation where the wiring harness is clamped too firmly or even stuck when the staff needs to test more wiring harnesses, causing the staff to have to use tools or violent disassembly to replace the old wiring harness, thereby affecting the staff's work efficiency and may cause damage to the detection machine body 1, thereby improving the use of the device.

[0033] When the staff needs to protect the surface of the dynamometer 2 from dust, they pull the operating plate 52 to make the operating plate 52 slide on the arc surface of the fixed rod 51, the second spring 56 is stretched, and the operating plate 52 drives the insertion rod 53 to move until the insertion rod 53 no longer blocks the movement of the protective cover 54. At this time, the protective cover 54 is pushed, and the protective cover 54 slides in the protective groove of the detection machine body 1 until the protective cover 54 covers the buttons of the dynamometer 2. At this time, the operating plate 52 is released, and the rebound force of the second spring 56 drives the operating plate 52 to slide on the arc surface of the fixed rod 51, and the operating plate 52 drives the insertion rod 53 to move until the insertion rod 53 is inserted into the slot of the protective cover 54. At this time, the dust-proof effect of the surface buttons of the dynamometer 2 is achieved, which avoids dust falling on the surface of the dynamometer 2 when the detection machine body 1 is idle for a long time, causing dust to enter the gaps between the buttons on the surface of the dynamometer 2, thereby causing the buttons of the dynamometer 2 to malfunction, thereby improving the protection of the device.
