Abstract
Description
Technical Field
[0001] This application relates to the field of wire harness positioning technology, specifically a wire harness sleeve through-hole positioning device. Background Technology
[0002] Wiring harness sleeves are rubber products used to protect wiring harnesses. They are widely used in the automotive and electronic equipment fields. Commonly used materials for wiring harness sleeves include natural rubber, neoprene rubber, silicone rubber, and EPDM rubber, among which EPDM rubber is the main material for automotive wiring harness sleeves.
[0003] After the outer sleeve is fully opened, when preparing to remove it, the sleeve exerts an inward force on the opening device, making it difficult for the wire harness to come out and causing subsequent processing difficulties. If multiple sets of corresponding roller structures are set inside the gripper, the wire harness can contact the roller structure when it is released. Through the rolling of the internal rollers, the wire harness can be released when the opening device retracts and better engage with the outer sleeve. Therefore, a wire harness sleeve through-hole positioning device is proposed to address the above situation. Utility Model Content
[0004] Technical problems to be solved To address the shortcomings of existing technologies, this application provides a wire harness sleeve through-hole positioning device, which has the advantage of facilitating wire harness removal.
[0005] To achieve the above objectives, this application provides the following technical solution: a wire harness sleeve through-hole positioning device, comprising a worktable, a sleeve support mechanism, a wire pulling mechanism, a wire clamping mechanism, and two support blocks. The sleeve support mechanism includes a square frame fixedly connected to the top of the two support blocks. A first electric push rod is fixedly installed on each of the four sides of the square frame. A support rod is fixedly connected to one end of the first electric push rod. A groove is provided on the side of the support rod, and several rollers are fixedly installed inside the groove. The above solution, by setting up a rubber sleeve support mechanism, enables the first electric push rod to push the support rod outward, thereby bringing the roller into contact with the wire harness. When the support rod retracts, the rolling of the roller reduces the friction between the wire harness and the support rod, thus helping the wire harness to be smoothly released. In addition, the roller structure design ensures that the wire harness remains stable during the release process, avoiding positional displacement caused by external forces. This structure not only improves the efficiency of wire harness release but also enhances the accuracy of the rubber sleeve's connection with the wire harness, providing convenient conditions for subsequent processing.
[0006] Furthermore, two support boxes are fixedly connected to the top of the workbench, and support blocks are inserted into the inside of the support boxes. Several threaded holes are opened inside the support boxes and the support blocks, and bolts are threaded into the inside of the threaded holes. The above solution, by setting up a cooperative structure between the support box and the support block, enables flexible adjustment of the wire harness sleeve through-hole positioning device according to the height of the staff. During adjustment, the connection method between the threaded hole and the bolt inside the support box allows the position of the support block to be fixed or moved according to actual needs, thereby adapting to the height requirements of different staff.
[0007] Furthermore, the cable pulling mechanism includes a support frame fixedly connected to the sides of the two support blocks, a hydraulic cylinder fixedly installed on the side of the support frame, and a hydraulic rod fixedly installed inside the hydraulic cylinder; The above solution, by setting up a wire-pulling mechanism, enables the hydraulic cylinder to achieve precise pulling of the wire harness through the extension and retraction of the hydraulic rod.
[0008] Furthermore, the side of the workbench is threaded with two screws, and the surfaces of the two screws are threaded with L-shaped blocks. The top of the L-shaped blocks is fixedly connected with a support column, and the top of the support column is fixedly connected with a retaining ring. The above solution, through the combination of screws and L-shaped blocks, enables the disassembly and replacement of the support column and fixing ring. The support column and fixing ring also serve to limit the movement of the wire harness.
[0009] Furthermore, four support legs are fixedly connected to the bottom of the workbench, and silicone pads are fixedly connected to the bottom of the support legs. The above solution, by setting up a combination structure of support legs and silicone pads, can effectively improve the overall stability of the device. At the same time, the material properties of the silicone pads can reduce the vibration and noise generated during the operation of the device, thereby providing a more stable working environment for wire harness processing.
[0010] Furthermore, the wire clamping mechanism includes two support plates fixedly connected to one end of the hydraulic rod, and a second electric push rod is fixedly installed inside the support plate, with a clamping block fixedly connected to one end of the second electric push rod; The above solution, by setting up a wire clamping mechanism, enables the second electric push rod and the clamping block to cooperate in a way that allows for stable clamping of the wire harness. When clamping the wire, after the hydraulic rod moves the support plate to the designated position, the second electric push rod can precisely adjust the position of the clamping block to accommodate wire harnesses of different diameters or shapes. This structure improves operational flexibility and effectively prevents damage to the wire harness due to improper clamping force.
[0011] Furthermore, two L-shaped plates are fixedly connected to the top of the frame, and cameras are fixedly installed on the sides of the two L-shaped plates; The above solution, by setting up a combination structure of camera and L-shaped plate, enables real-time monitoring of wire harnesses during the processing.
[0012] Furthermore, the surface of the support rod is provided with a sponge sleeve, handles are fixedly connected to both sides of the frame, and rubber pads are fixedly connected to the surface of the clamping block; The above solution, by setting a sponge sleeve, can protect the rubber sleeve and prevent the supporting force of the support rod from causing cracks on the surface of the rubber sleeve. The handle makes it easier for operators to apply force when moving or adjusting the device, enhancing the overall portability and ease of operation. Finally, the rubber pad provides additional protection when clamping the wire harness, avoiding wear or damage to the wire harness surface due to direct contact, thus improving the safety and practicality of the device.
[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects: This wire harness sleeve through-hole positioning device, through the setting of a sleeve support mechanism, enables the first electric push rod to push the support rod outward, thereby bringing the roller into contact with the wire harness. When the support rod retracts, the rolling of the roller reduces the friction between the wire harness and the support rod, thus helping the wire harness to be smoothly released. In addition, the design of the roller structure also ensures that the wire harness remains stable during the release process, avoiding positional displacement caused by external forces. This structure not only improves the efficiency of wire harness release but also improves the accuracy of the sleeve-wire harness connection, providing convenient conditions for subsequent processing.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0017] Please see Figure 4 and Figure 5 The wire harness sleeve through-hole positioning device in this embodiment includes a workbench 1, a sleeve support mechanism 3, a wire pulling mechanism 4, a wire clamping mechanism 11, and two support blocks 14. The sleeve support mechanism 3 includes a square frame 301 fixedly connected to the top of the two support blocks 14. First electric push rods 302 are fixedly installed on all four sides of the square frame 301. A support rod 303 is fixedly connected to one end of the first electric push rod 302. A groove 304 is opened on the side of the support rod 303. Several rollers 305 are fixedly installed inside the groove 304. By setting the sleeve support mechanism 3, The first electric push rod 302 can push the support rod 303 outward, thereby causing the roller 305 to contact the wire harness. When the support rod 303 retracts, the rolling of the roller 305 can reduce the friction between the wire harness and the support rod 303, thus helping the wire harness to be smoothly released. In addition, the design of the roller 305 structure can also ensure that the wire harness remains stable during the release process and avoid positional displacement caused by external forces. This structure not only improves the efficiency of wire harness release, but also improves the accuracy of the connection between the rubber sleeve and the wire harness, providing convenient conditions for subsequent processing.
[0018] Please see Figure 3 and Figure 6Two support boxes 2 are fixedly connected to the top of the workbench 1. Support blocks 14 are inserted into the inside of the support boxes 2. Several threaded holes 15 are opened inside the support boxes 2 and the support blocks 14. Bolts 16 are threadedly connected inside the threaded holes 15. By setting the cooperation structure between the support boxes 2 and the support blocks 14, the wire harness sleeve through-hole positioning device can be flexibly adjusted according to the height of the staff. During adjustment, the connection method of the threaded holes 15 and the bolts 16 inside the support boxes 2 allows the position of the support blocks 14 to be fixed or moved according to actual needs, thereby adapting to the height needs of different staff. The wire pulling mechanism 4 includes a support frame 401 fixedly connected to the sides of the two support blocks 14. A hydraulic cylinder 402 is fixedly installed on the side of the support frame 401. A hydraulic rod 403 is fixedly installed inside the hydraulic cylinder 402. By setting the wire pulling mechanism 4, the hydraulic cylinder 402 can achieve the effect of precise pulling operation of the wire harness through the extension and retraction movement of the hydraulic rod 403.
[0019] Please see Figure 1 The workbench 1 has two screws 6 threadedly connected to its side. L-shaped blocks 5 are threadedly connected to the surfaces of the two screws 6. A support column 7 is fixedly connected to the top of the L-shaped block 5, and a retaining ring 8 is fixedly connected to the top of the support column 7. This cooperative structure of screws 6 and L-shaped blocks 5 allows for the disassembly and replacement of the support column 7 and retaining ring 8. The support column 7 and retaining ring 8 also serve to limit the movement of the wire harness. Four support legs 9 are fixedly connected to the bottom of the workbench 1. Silicone pads 10 are fixedly connected to the bottom of the support legs 9. This combination of support legs 9 and silicone pads 10 effectively improves the overall stability of the device. Furthermore, the material properties of the silicone pads 10 reduce vibration and noise generated during operation, thus providing a more stable working environment for wire harness processing.
[0020] Please see Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7The wire clamping mechanism 11 includes two support plates 1101 fixedly connected to one end of the hydraulic rod 403. A second electric push rod 1102 is fixedly installed inside the support plate 1101. A clamping block 1103 is fixedly connected to one end of the second electric push rod 1102. By setting the wire clamping mechanism 11, the cooperation structure between the second electric push rod 1102 and the clamping block 1103 can achieve a stable clamping effect on the wire harness. When clamping the wire, after the hydraulic rod 403 drives the support plate 1101 to a designated position, the second electric push rod 1102 can precisely adjust the position of the clamping block 1103 to adapt to wire harnesses of different diameters or shapes. This structure improves the flexibility of operation and can also effectively avoid damage to the wire harness due to improper clamping force. Two L-shaped plates 12 are fixedly connected to the top of the frame 301. A camera 13 is fixedly installed on the side of the L-shaped plate 12. By setting up the combination structure of the camera 13 and the L-shaped plate 12, the wire harness can be monitored in real time during the processing. The surface of the support rod 303 is provided with a sponge sleeve 17. Handles 18 are fixedly connected to both sides of the frame 301. A rubber pad 19 is fixedly connected to the surface of the clamping block 1103. By setting the sponge sleeve 17, the rubber sleeve can be protected to prevent the supporting force of the support rod 303 from causing cracks on the surface of the rubber sleeve. The handle 18 makes it easy for the operator to apply force when moving or adjusting the device, which enhances the overall portability and ease of operation. Finally, the rubber pad 19 provides additional protection when clamping the wire harness, avoiding wear or damage to the surface of the wire harness due to direct contact, thus improving the safety and practicality of the device.
[0021] In this embodiment, the wire harness sleeve through-hole positioning device is characterized by a sleeve support mechanism 3. This mechanism enables the first electric push rod 302 to push the support rod 303 outward, thereby bringing the roller 305 into contact with the wire harness. When the support rod 303 retracts, the rolling motion of the roller 305 reduces the friction between the wire harness and the support rod 303, thus facilitating the smooth release of the wire harness. Furthermore, the design of the roller 305 structure ensures the stability of the wire harness during the release process, preventing positional shifts caused by external forces. This structure not only improves the efficiency of wire harness release but also enhances the accuracy of the sleeve-wire harness connection, providing convenient conditions for subsequent processing.
[0022] The working principle of the above embodiment is as follows: First, the position of the support block 14 in the support box 2 is adjusted according to the height of the worker. Then, the support block 14 is fixed at a suitable height by the cooperation of the bolt 16 and the threaded hole 15 to accommodate workers of different heights. Then, the worker passes one end of the wire harness that needs to pass through the rubber sleeve through the fixing ring 8. The fixing ring 8 plays a preliminary limiting role to ensure that the wire harness enters the device in the correct direction. Subsequently, the rubber sleeve is passed through the surface of the four support rods 303. Then, the rubber sleeve supporting mechanism 3 is activated. The first electric push rod 302 pushes the support rod 303 to move outward and open the rubber sleeve to prepare for the wire harness to be passed through. Then, the wire pulling mechanism 4 starts to work, and the hydraulic cylinder 40 2. The hydraulic rod 403 extends, driving the wire clamping mechanism 11 to move to the position where the wire harness is to be clamped. Then, the second electric push rod 1102 in the wire clamping mechanism 11 pushes the clamping block 1103 to close, stably clamping the wire harness. At the same time, the camera 13 monitors the position of the wire harness wrapping in real time. Finally, the hydraulic cylinder 402 drives the hydraulic rod 403 to retract, pulling the wire harness through the already opened rubber sleeve. When it reaches the wrapping position, the first electric push rod 302 controls the support rod 303 to slowly retract. The rolling of the roller 305 reduces the friction between the wire harness and the support rod 303, allowing the wire harness to smoothly exit the opening mechanism. At the same time, the rubber sleeve tightly fits around the wire harness under its own elasticity, thus completing the entire through-hole positioning process.
