Description

Technical Field

[0001] This utility model relates to the field of wire harness auxiliary positioning technology, specifically an auxiliary positioning device for wire harness processing. Background Technology

[0002] With the diversification of electronic devices, wire harnesses are becoming increasingly diverse, including various shapes and specifications such as round, flat, and multi-core. During wire harness processing, auxiliary positioning devices are used to accurately fix and guide the wire harness in position, facilitating subsequent processing operations such as cutting, stripping, welding, and assembly. Existing positioning devices typically have fixed positioning blocks, often only suitable for a specific type of wire harness. When processing different types of wire harnesses, additional positioning devices must be purchased, which not only wastes time and money but also reduces production efficiency.

[0003] To address this issue, we designed an auxiliary positioning device for wire harness processing. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary positioning device for wire harness processing to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides an auxiliary positioning device for wire harness processing, including a base. A movable plate is symmetrically arranged on the top of the base, and the base and the movable plate are slidably connected. A handwheel is installed on one side of the base, and a bidirectional lead screw is fixedly connected to the side of the handwheel. The bidirectional lead screw passes through the movable plate and is threadedly connected to the movable plate. A locking part is fixedly connected to the top of the movable plate, and a locking plate is fixedly connected to the locking part. The locking plates are spaced apart, and a flat plate is locked to the locking part. A through groove is vertically opened on the flat plate, and the through groove locks to the locking plate. An arc-shaped plate is fixedly connected to one side of the flat plate, and the side of the arc-shaped plate away from the flat plate is an arc surface.

[0006] Furthermore, the card plate is made of electrical pure iron, and the flat plate is made of neodymium iron boron.

[0007] Furthermore, the card plate is fixedly connected to two card blocks with a triangular cross-section on both sides, and the through groove is provided on both sides to cooperate with the card blocks, and the card slots are engaged with the card blocks.

[0008] Furthermore, a limiting rod is fixedly connected to the base. The limiting rod is located on one side of the bidirectional lead screw, and the limiting rod passes through the moving plate and is slidably connected to the moving plate.

[0009] Furthermore, a first telescopic rod is fixedly installed on one side of the movable plate, and the end of the first telescopic rod away from the movable plate is fixedly installed on the side of the snap-fit ​​part. A knob-type positioner is fixedly installed around the periphery of the first telescopic rod.

[0010] Furthermore, an anti-slip layer is bonded to the side of the curved plate that is far from the flat plate.

[0011] Furthermore, the limiting rod is made of stainless steel.

[0012] Furthermore, a second telescopic rod is fixedly connected to the top of the movable plate, and the top end of the second telescopic rod is fixedly connected to the inner cavity of the snap-fit ​​part.

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

[0014] 1. The device uses fixedly spaced clamping plates on the clamping part. A through groove is opened on the flat plate to clamp the clamping plate. An arc-shaped plate is connected to one side of the flat plate. When fixing a cylindrical wire harness, the flat plate is clamped onto the clamping part, so that the arc-shaped plates are far apart. The cylindrical wire harness is fixed by using the opposite surfaces of the flat plates. When fixing a flat wire harness, the flat plate is pulled out and flipped, and then re-clamped with the clamping plate. The flat wire harness is fixed by using the arc-shaped plate. This facilitates switching of positioning modules, allowing the same positioning device to adapt to different types of wire harness processing, improving the versatility and flexibility of the equipment, and increasing production efficiency.

[0015] 2. By manually loosening the knob-type positioner, the locking part is pulled to a suitable height. The extension length of the first telescopic rod is fixed by tightening the knob-type positioner, thereby locking the position of the locking part. This meets the needs of processing wire harnesses of different specifications and enhances the adaptability of the entire auxiliary positioning device. Attached Figure Description

[0021] 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.

[0022] Please see Figures 1-4 This utility model provides a technical solution: an auxiliary positioning device for wire harness processing, including a base 1, with movable plates 8 symmetrically arranged on the top of the base 1, the base 1 and the movable plates 8 being slidably connected, a handwheel 2 installed on one side of the base 1, and a bidirectional lead screw 3 fixedly connected to the side of the handwheel 2 by a key to ensure that the two rotate synchronously, the two ends of the bidirectional lead screw 3 are respectively mounted on the base 1 through bearing seats, and the thread directions of the bidirectional lead screw 3 are opposite to realize the relative or opposite movement of the two movable plates 8, the bidirectional lead screw 3 passes through the movable plates 8 and is threadedly connected to the movable plates 8, a snap-fit ​​part 4 is fixedly connected to the top of the movable plates 8, a snap-fit ​​plate 9 is fixedly connected to the snap-fit ​​part 4, the snap-fit ​​plates 9 are spaced apart, a flat plate 5 is snapped into the snap-fit ​​part 4, a through groove 10 is vertically opened on the flat plate 5, the through groove 10 is snapped into the snap-fit ​​plate 9, an arc plate 6 is fixedly connected to one side of the flat plate 5, the side of the arc plate 6 away from the flat plate 5 is an arc surface.

[0023] In practice, to fix a cylindrical wire harness, first attach the flat plate 5 to the snap-fit ​​part 4 through the through slot 10, ensuring that the two flat plates 5 are on the inside, while the connected arc plates 6 are far apart. Then, turn the handwheel 2, which drives the bidirectional screw 3 to rotate synchronously. The two moving plates 8 move the snap-fit ​​part 4, the flat plate 5, and the arc plates 6 closer together, thus fixing the cylindrical wire harness. When fixing a flat wire harness, first pull the flat plate 5 out of the snap-fit ​​part 4 and flip it over, then snap the flat plate 5 into the snap-fit ​​part 4, bringing the two arc plates 6, which were originally far apart, closer together. Then, turn the handwheel 2 again, which drives the moving plate 8 to move through the bidirectional screw 3, using the adjusted arc plates 6 to fix the flat wire harness.

[0024] See Figures 1-2 As shown, the flat plate 5 is made of neodymium iron boron, and the card plate 9 is made of electrical pure iron, which gives the card plate 9 a high magnetic permeability. It can be magnetized under the magnetic field of the flat plate 5, thereby generating an attraction force with the flat plate 5 and enhancing the stability of the connection between the flat plate 5 and the card connector 4. The curved plate 6 and the side of the flat plate 5 that are far away from each other are both bonded with an anti-slip layer. The anti-slip layer is made of rubber and has raised particles on the surface to increase the friction between it and the wire harness.

[0025] See Figure 2 The card plate 9 is fixedly connected to the card blocks 14 with a triangular cross-section on both sides. The through groove 10 has slots 15 on both sides that cooperate with the card blocks 14. The slots 15 engage with the card blocks 14 to further stabilize the connection between the flat plate 5 and the card plate 9, assist in magnetic adsorption, and prevent the flat plate 5 from accidentally loosening or shifting during use.

[0026] See Figure 1 A limiting rod 7 is fixedly connected to the base 1. The limiting rod 7 is made of stainless steel with a smooth surface to reduce frictional resistance between it and the moving plate 8. The limiting rod 7 is located on one side of the bidirectional lead screw 3. The limiting rod 7 passes through the moving plate 8 and is slidably connected to the moving plate 8, restricting the moving direction of the moving plate 8 so that it can only move along the axial direction of the limiting rod 7, preventing it from shifting or shaking during movement, and improving the accuracy of the moving plate 8 after position adjustment.

[0027] See Figure 4 A first telescopic rod 11 is fixedly installed on one side of the movable plate 8. The end of the first telescopic rod 11 away from the movable plate 8 is fixedly installed on the side of the snap-fit ​​part 4. A knob-type positioner 12 is fixedly installed on the periphery of the first telescopic rod 11 by bolts. The knob-type positioner 12 is used to fix the telescopic length of the first telescopic rod 11. When processing flat wire harnesses of different specifications, the position of the snap-fit ​​part 4 needs to be adjusted due to the different dimensions such as the width and thickness of the wire harnesses. At this time, the knob-type positioner 12 is manually loosened, the snap-fit ​​part 4 is pulled to a suitable height, and the telescopic length of the first telescopic rod 11 is fixed by tightening the knob-type positioner 12, thereby locking the position of the snap-fit ​​part 4.

[0028] See Figure 3 A second telescopic rod 13 is fixedly connected to the top of the movable plate 8. The top end of the second telescopic rod 13 is fixedly connected to the inner cavity of the locking part 4, assisting the first telescopic rod 11 and further enhancing the stability of the connection between the locking part 4 and the movable plate 8.

[0029] Working principle:

[0030] To process a cylindrical wire harness, the flat plate 5 is inserted into the locking part 4 via the through groove 10, with the two flat plates 5 facing inwards and the curved plate 6 naturally separated. To process a flat wire harness, the flat plate 5 is pulled out, flipped, and then inserted back in, bringing the curved plate 6 closer together. Then, the handwheel 2 is turned, causing the bidirectional lead screw 3 to rotate synchronously. Because the threads at both ends of the lead screw are opposite, the moving plate 8 moves the locking part 4, the flat plate 5, and the curved plate 6 to fix the wire harness. The moving plate 8 is restricted by the limiting rod 7 and can only move along its axial direction.

[0031] If different specifications of flat wire harnesses require adjustment of the position of the locking part 4, loosen the knob-type positioner 12, pull the locking part 4 to the appropriate height, and then tighten the position. The second telescopic rod 13 assists the first telescopic rod 11 to secure the connection between the locking part 4 and the moving plate 8. The neodymium iron boron flat plate 5 and the electrical pure iron locking plate 9 are magnetized to generate an attraction force, enhancing the stability of the locking between the locking plate 9 and the flat plate 5. The rubber anti-slip layer on the outer side of the arc plate 6 and the flat plate 5 increases the friction with the wire harness, ensuring stable fixing and processing.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
