Description

Technical Field

[0001] The present application relates to the technical field of automobile wiring harnesses, and in particular to a positioning device for automobile wiring harnesses. Background Art

[0002] Automotive wiring harness refers to the combination of cables used in the automotive electrical system, which is mainly used to connect and transmit power, signals and data, and complete the communication and control between various electrical equipment in the vehicle. Automotive wiring harness is generally composed of wires, insulating sheaths, terminal blocks and wrapping materials.

[0003] Automotive wiring harnesses require positioning (i.e., compression and limiting) during the production and processing process. After being compressed, wrinkles may form near the compressed area. These wrinkles may become areas of stress concentration, increasing the risk of cable wear and breakage at bends, while increasing the difficulty of processing and assembling the wiring harnesses. Utility Model Content

[0004] In view of this, the purpose of the present invention is to solve the shortcomings of the background technology and to propose a positioning device for an automobile wiring harness to solve the problems existing in the prior art.

[0005] To achieve the above purpose, the utility model provides a positioning device for an automotive wiring harness, comprising a base, the top of the base is fixedly connected to a positioning lower bracket, the top of the positioning lower bracket is fixedly connected to a guide rod, the outer surface of the guide rod is slidably connected to a positioning upper bracket, the top of the positioning lower bracket is rotatably connected to a screw, and the outer surface of the screw is threadedly sleeved with the inner surface of the positioning upper bracket, a knob is provided on the top of the screw, a guide rail is provided inside the base, the outer surface of the guide rail is slidably connected to a slide through a driving mechanism, and a wrinkle removal mechanism is provided on the slide.

[0006] Preferably, the driving mechanism includes a motor fixedly installed inside the base, the output end of the motor is fixedly connected to a rotating frame, and both ends of the rotating frame are fixedly penetrated by end shafts. The wrinkle removal mechanism can be displaced by the driving mechanism to smoothly remove wrinkles.

[0007] Preferably, the outer surface of the end shaft is rotatably connected to a connecting frame, a central shaft is fixedly penetrated through the inner side of the slide, and the outer surface of the central shaft is rotatably connected to an end of the connecting frame away from the end shaft.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The positioning device for automotive wiring harnesses uses springs and slide bars to achieve flexible clamping of the wiring harness. When the upper and lower sets of clamps slide along the surface of the wiring harness, they actually physically smooth the wiring harness. This treatment can eliminate tiny wrinkles and uneven parts on the wiring harness, making it smoother and neater, and further improving its appearance quality and reliability.

[0013] 2. The positioning device for automotive wiring harnesses uses the knob and screw in conjunction with the relative positioning of the guide rod.

Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0018] See also Figure 1-2A positioning device for an automotive wiring harness comprises a base 1, the top of the base 1 is fixedly connected to a positioning lower bracket 2, the top of the positioning lower bracket 2 is fixedly connected to a guide rod 3, the outer surface of the guide rod 3 is slidably connected to a positioning upper bracket 4, the top of the positioning lower bracket 2 is rotatably connected to a screw rod 5, and the outer surface of the screw rod 5 is threadedly sleeved with the inner surface of the positioning upper bracket 4, a knob 6 is provided on the top of the screw 5, a guide rail 11 is provided inside the base 1, the outer surface of the guide rail 11 is slidably connected to a slide 12 through a driving mechanism, and a wrinkle removal mechanism is provided on the slide 12.

[0019] Through the above technical solution, during use of the device, the automobile wiring harness needs to be placed in the arc groove on the surface of the positioning lower bracket 2. In the process of rotating the knob 6 to drive the screw 5 to rotate, the positioning upper bracket 4 can gradually approach the wiring harness under the relative limiting action of the guide rod 3 until it is stably squeezed. During this period, the surface of the wiring harness can be wrinkled by cooperating with the wrinkle removal mechanism through the driving mechanism.

[0020] Specifically, the driving mechanism includes a motor 7 fixedly installed inside the base 1 , an output end of the motor 7 is fixedly connected to a rotating frame 8 , and end shafts 9 are fixedly passed through both ends of the rotating frame 8 .

[0021] Through the above technical solution, the end shaft 9 will make a circular motion during the rotation of the rotating frame 8, and due to the symmetrical distribution of the end shaft 9, it can synchronously drive the corresponding connecting frame 10.

[0022] Specifically, the outer surface of the end shaft 9 is rotatably connected to the connecting frame 10, the inner side of the slide 12 is fixedly penetrated by a central shaft 13, and the outer surface of the central shaft 13 is rotatably connected to the end of the connecting frame 10 away from the end shaft 9.

[0023] Through the above technical solution, both ends of the connecting frame 10 are concave in design so as to smoothly rotate between the end shaft 9 and the central shaft 13 , and the central shaft 13 is designed to be in the middle position of the slide 12 .

[0024] Specifically, the wrinkle removal mechanism includes a support rod 14 fixedly connected to the top of the slide 12 , and a lower clamping plate 15 is fixedly connected to the top of the support rod 14 .

[0025] Through the above technical solution, strip-shaped holes are opened on the upper surface of the base 1, and the support rods 14 pass through these strip-shaped holes and are fixedly connected to the corresponding lower clamping plates 15 respectively.

[0026] Specifically, the top of the lower clamping plate 15 is fixedly connected to a slide rod 16 , and the outer surface of the slide rod 16 is slidably connected to the upper clamping plate 17 .

[0027] Through the above technical solution, the same number of arc grooves are opened on the corresponding sides of the positioning lower clamping frame 2, the positioning upper clamping frame 4 and the lower clamping plate 15 and the upper clamping plate 17. The positions of the arc grooves correspond to each other in order to clamp the automobile wiring harness.

[0028] Specifically, a spring 18 is movably sleeved on the outer surface of the slide bar 16 , and two ends of the spring 18 are fixedly connected to the upper surface of the lower clamping plate 15 and the lower surface of the upper clamping plate 17 respectively.

[0029] Through the above technical solution, the spring 18 is designed to enable the upper clamping plate 17 and the lower clamping plate 15 to squeeze and clamp the automobile wiring harness with a flexible force, and the two sets of clamping plates can slide along the surface of the wiring harness during movement.

[0030] Working principle: In the process of positioning the automobile wiring harness, the device needs to place the automobile wiring harness belt clamping part in the arc groove on the surface of the positioning lower clamp 2, and then in the process of rotating the knob 6 to drive the screw 5, the positioning upper clamp 4 can be gradually approached to the wiring harness under the relative limiting action of the guide rod 3, until the wiring harness is stably squeezed by cooperating with the positioning lower clamp 2, and the automobile wiring harness is stably positioned. During this period, in order to reduce the wrinkles near the wiring harness positioning, it is necessary to first pull up the upper clamp 17 and make it slide along the slide bar 16, thereby stretching the spring 18, and then place the front and rear parts near the wiring harness positioning on the corresponding lower clamp 15 respectively (the wiring harness is in the arc groove on the surface of the lower clamp 15), and finally release the upper clamp 17. Under the elastic reset action of the spring 18, the upper clamp 17 will slide down along the slide bar 16, thereby pressing on the wiring harness with an appropriate force. At this time, the wiring harness is held by the lower clamp 15 is flexibly clamped with the upper card plate 17, and then the motor 7 is turned on to drive the rotating frame 8 to rotate. The corresponding connecting frame 10 can be synchronously driven through the end shafts 9 at both ends, that is, the central axis 13 is pushed by the connecting frame 10, so that the slide 12 is driven during the rotation of the connecting frame 10 along the central axis 13, so that the slide 12 slides along the guide rail 11, and then the lower card plate 15 is linked to move synchronously through the support rod 14. In the process of the upper and lower sets of card plates flexibly clamping the wire harness and sliding along its surface, the elastic force of the spring 18 not only improves the clamping stability of the wire harness, but also can fine-tune the wire harness to a certain extent to adapt to the change of its shape. In the process of the upper and lower sets of card plates sliding along the surface of the wire harness, the wire harness is actually physically smoothed. This sliding smoothing effect helps to eliminate tiny wrinkles and uneven parts on the wire harness, making the wire harness smoother and tidier.
