Description

Technical Field

[0001] This utility model belongs to the field of automotive wiring harness production technology, and in particular relates to a rubber sleeve machine for automotive wiring harness production. Background Technology

[0002] Automotive wiring harnesses are core components in automotive circuit networks that connect the electrical and electronic parts of a vehicle. During the production process of automotive wiring harnesses, a sleeve-making machine is used to evenly spread the sleeves and cover the wiring harnesses to protect the wires, prevent electromagnetic interference and radio frequency interference, provide dust and water protection, and fire and flame retardancy, thereby improving the safety of the vehicle.

[0003] As disclosed in the utility model with authorization announcement number CN221660081U, a rubber sleeve machine for producing automotive wiring harnesses includes a housing. A control panel is installed on the outer surface of the housing. A fixing plate two is fixedly connected to the inner side wall of the housing. A slot is opened on the front of the fixing plate two. Two sets of expansion mechanisms are slidably connected inside the slot of the fixing plate two. A positioning mechanism that can limit the movement range of the two sets of expansion mechanisms is installed between the inner side walls of the two sides of the housing. A feeding mechanism that can drive the rubber sleeve to move is installed on the top of the inner wall of the housing. The positioning mechanism can limit the movement range of the two sets of expansion mechanisms, thereby avoiding excessive expansion between the two sets of expansion mechanisms and causing deformation and damage to the rubber sleeve. Therefore, the yield of the equipment when producing wiring harnesses is improved. The feeding mechanism pulls the rubber sleeve to move, so that the feeding mechanism replaces manual loading and unloading of rubber sleeves, thereby improving the production efficiency of the equipment. However, in the application of this technical solution, the rubber sleeve becomes more constricted on the expansion plate after it is stretched, making it inconvenient to remove and put on the automotive wiring harness. In addition, the length of the expansion plate is fixed, while the length of the rubber sleeve varies for different wiring harnesses. This presents a technical problem that it is not convenient and quick to remove the expanded rubber sleeve from the wiring harness and adjust the length of the expansion plate to accommodate rubber sleeves of different lengths.

The length of the expansion plate can be easily adjusted by pulling the extension plate to accommodate sleeves of different lengths, which makes it easier to put the sleeve on the wire harness and improves the applicability of the equipment.

[0014] 2. This utility model has a disassembly and assembly component between the front end of one side of the connecting plate and the rear end of the outer side of the expansion plate. When in use, the expansion plate is placed horizontally and the mating square hole is aligned with the positioning square rod. Then, the connecting sleeve is rotated and fixed to the mounting column through the threaded connection. This achieves the purpose of installing and fixing the expansion plate on the front end of one side of the connecting plate, and facilitates the disassembly of the expansion plate. This makes it easy to disassemble and assemble the expansion plate for replacement and maintenance of the expansion components. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-4As shown, this utility model is a rubber sleeve machine for automotive wiring harness production, including a base 1, and further including: a groove 2 provided on the top of the base 1, a synchronous cylinder 4 passing through the middle position of both sides of the groove 2, a connecting plate 3 provided in the groove 2 on one side of the synchronous cylinder 4, and an arc-shaped expansion plate 7 provided at the front end of one side of the connecting plate 3. When using the equipment, the rubber sleeve is fitted between the outside of the unexpanded expansion plate 7, and then the synchronous cylinder 4 is started to drive the expansion plate 7 to move in the opposite direction to expand the rubber sleeve. Then, the automotive wiring harness is passed through the inside of the rubber sleeve and the expansion plate 7 is moved in opposite directions to fit the rubber sleeve onto the wiring harness. A limit rod 6 is provided at the rear end of the other side of the connecting plate 3, and stabilizing holes 5 are provided at the rear ends of both sides inside the groove 2. One end of the limit rod 6 passes through the inside of the stabilizing hole 5, and the diameter of the limit rod 6 is smaller than the diameter of the stabilizing hole 5. When the device is running, the limit rod 6 moves with the connecting plate 3 and moves within the stabilizing hole 5 to stabilize it and the expansion plate 7.

[0024] As a further implementation of this embodiment, such as Figure 1-4 As shown, the expansion plate 7 has a reserved groove 11 inside. A detachment guide wheel 10 is rotatably connected between the two ends of the reserved groove 11. The detachment guide wheels 10 are arranged at equal intervals between the two ends of the reserved groove 11. The edges of the detachment guide wheels 10 are rounded. When fitting the rubber sleeve onto the wire harness, the detachment guide wheels 10 facilitate sliding the wire harness rubber sleeve onto the outside of the expansion plate 7. Furthermore, after the wire harness is inserted into the expanded rubber sleeve, it is easy to remove the rubber sleeve and place it on the outside of the wire harness, thus preventing the expansion plate 7 from expanding and causing the rubber sleeve to become too tight and difficult to remove. The rounded edges of the detachment guide wheels 10 prevent scratching the rubber sleeve or the outer sheath of the wire harness. The expansion plate 7 has limiting guide grooves 12 at both ends inside, and these limiting guide grooves 12 are symmetrically arranged inside the expansion plate 7. An extension plate 9 is embedded on the outside of the limiting guide grooves 12. Moving sliders 13 are provided at both ends of the inner side of the expansion plate 7. The vertical cross section is convex. The outer end of the movable slider 13 passes through the limiting guide groove 12 and is fixedly connected to one end of the inner side of the extension plate 9. The movable slider 13 can slide back and forth in the limiting guide groove 12, so that the extension plate 9 can be pulled out and the length of the expansion plate 7 can be easily adjusted to accommodate different lengths of rubber sleeves, thereby making it easier to install rubber sleeves on the wire harness and improve equipment applicability.

[0025] As a further implementation of this embodiment, such as Figure 1 , Figure 3 and Figure 4As shown, a disassembly and assembly assembly is provided between the front end of one side of the connecting plate 3 and the rear end of the outer side of the expansion plate 7. The disassembly and assembly assembly includes a connecting sleeve 8, which is rotatably connected to the front end of one side of the connecting plate 3. A mounting post 16 is provided at the middle position of the rear end of the outer side of the expansion plate 7. A mating square hole 15 is provided inside the mounting post 16. A positioning square rod 14 is provided at the middle position of one side of the inner side of the connecting sleeve 8. The mounting post 16 is inserted into the inner side of the connecting sleeve 8. An external thread is provided on the outer side of the mounting post 16. An internal thread that matches the external thread of the mounting post 16 is provided on the inner side wall of the connecting sleeve 8. The threaded connection facilitates the connection and fixation of the connecting sleeve 8 and the mounting post 16. The positioning square rod 14 fits into the mating square hole 15. The expansion plate 7 can be positioned and installed using the mating positioning square rod 14 and the mating square hole 15, thereby achieving the effect of convenient disassembly and assembly of the expansion plate 7 for replacement and maintenance of the expansion components.

[0026] Working principle: When using the sleeve fitting machine, first place the expansion plate 7 horizontally and align the mating square hole 15 with the positioning square rod 14. Then, fix the connecting sleeve 8 to the mounting post 16 through the threaded connection. The expansion plate 7 can then be installed and fixed on one front end of the connecting plate 3. Adjust the applicable length of the expansion plate 7 by pulling the extension plate 9 according to the sleeve length. Then, fit the sleeve between the outer sides of the unexpanded expansion plate 7 and start the synchronous cylinder 4. At the same time, the connecting plate 3 drives the expansion plate 7 to move in the opposite direction to expand the sleeve. Then, pass the automotive wiring harness through the inside of the sleeve and move the expansion plate 7 towards each other. The release guide wheel 10 can be used to easily slide the wiring harness sleeve between the outer sides of the expansion plate 7. At the same time, the limiting rod 6 moves with the connecting plate 3 and moves within the stabilizing hole 5 to stabilize it and the expansion plate 7, thereby performing efficient and stable sleeve fitting operation for automotive wiring harnesses.
