Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness processing technology, specifically to an assembly fixture for automotive wiring harnesses. Background Technology

[0002] The assembly fixtures for automotive wiring harnesses are called automotive wiring harness fixtures, automotive wiring harness fixture plates, automotive wiring harness wiring fixture plates, automotive wiring harness fixture frames, etc. The plates are equipped with drawings, and the node positions are equipped with wiring harness jigs, which makes it easy for workers to perform wiring, install connectors, and cover sleeves according to the drawings.

[0003] There are generally three types of existing assembly fixtures for automotive wiring harnesses. One type has a fixture plate set on a metal bracket, which is placed on the ground and remains stationary. This type has a simple structure and low cost. Another type has multiple fixtures connected to a chain conveyor structure. The chain conveyor structure allows multiple fixtures to circulate and form an assembly line, with multiple workers performing multiple processes to speed up assembly efficiency. The last type is a larger metal bracket with several storage spaces inside. This makes it convenient to store accessories such as wires, connectors, tapes, and corrugated tubing used in assembling wiring harnesses. Compared to the first two types, this type has more storage space and does not require workers to walk further to the shelves to retrieve goods.

[0004] Existing fixture plates typically use surface openings to allow wire harness jigs to be mounted on the fixture plate via their tail screws. This structure presents two problems: First, disassembly and assembly are cumbersome, requiring operators to rotate the jig multiple times before tightening it with a wrench. Excessive torque can damage the substrate and drawings, while insufficient torque can cause loosening and affect subsequent assembly. Second, there is the issue of jig orientation. Due to thread precision and jig insertion methods, the orientation of the jig may deviate after tightening. If the orientation deviation is too large, it can cause interference during subsequent wiring, affecting the continuity of wiring. Therefore, operators need to remove and reinstall the jig. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an assembly tooling for automotive wiring harnesses to solve the technical problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an assembly fixture for automotive wiring harnesses, comprising a base plate, an adsorption block embedded on the surface of the base plate, a strong magnet connected to the outer surface of the adsorption block, and a support rod connected to the outer surface of the strong magnet; an insertion rod penetrating through the middle of the back of the support rod, and a spring connecting the insertion rod and the support rod; a lever penetrating through the top of the insertion rod; and a sliding groove formed at the top of the support rod.

[0007] By adopting the above technical solution, during on-site assembly and debugging before the tooling is used, the worker pulls the lever to retract the insert rod into the support rod and compress the spring. Then, the worker slowly places the strong magnet so that it adheres to the adsorption block. After that, the worker can release the lever. When the worker adjusts the position of the fixture so that the strong magnet is completely aligned with the adsorption block, the lever is driven by the spring to pass through the adsorption block. Then, the worker can use both hands to forcefully twist and adjust the orientation of the fixture head so that the orientation of the fixture head corresponds to the wiring direction, which facilitates subsequent adjustments. At this time, the insert rod bears the radial force to prevent the strong magnet from sliding on the plane, while the strong magnet bears the axial force to prevent the support rod from separating from the tooling, thus improving structural stability.

[0008] Furthermore, the strong magnet is an N42 neodymium iron boron magnet, and the surface of the strong magnet is coated with an epoxy resin layer.

[0009] By adopting the above technical solution, N42 neodymium iron boron magnets achieve a high balance between cost and magnetic attraction, i.e., a high cost-performance ratio. Higher grade magnets have greater magnetic attraction but higher costs, while lower grade magnets have less magnetic attraction but less cost savings. Furthermore, using N42 neodymium iron boron magnets can ensure magnetic attraction strength, prevent structural loosening and detachment, and allow the fixture to be disassembled by workers using both hands. During this process, the epoxy resin coating provides a protective effect, reducing the occurrence of damage to the strong magnets from impacts.

[0010] Furthermore, the strong magnet is detachably connected to the adsorption block, and both the strong magnet and the adsorption block are circular.

[0011] By adopting the above technical solution, a strong magnet is used to attract the fixture to the surface of the adsorption block, thereby achieving quick assembly and disassembly. The orientation of the fixture head can be adjusted by twisting it with both hands to make the fixture head face the wiring direction, and subsequent adjustments are convenient.

[0012] Furthermore, the insertion rod is slidably connected to the support rod, and the insertion rod is detachably connected to the adsorption block.

[0013] By adopting the above technical solution, when the staff adjusts the position of the fixture so that the strong magnet is completely aligned with the adsorption block, the lever is driven by the spring to pass through the adsorption block.

[0014] Furthermore, the lever is slidably connected to the slide groove.

[0015] By adopting the above technical solution, when the fixture needs to be replaced during subsequent maintenance, or when the drawings need to be changed, the staff can pull the lever to retract the insert rod into the support rod. Then, they can grasp the support rod and apply both radial and axial forces to disassemble it. Compared with axially pulling the support rod to disassemble it, it is more labor-saving and convenient.

[0016] Furthermore, multiple adsorption blocks, strong magnets, support rods, insertion rods, levers, springs, and sliding grooves are provided.

[0017] By adopting the above technical solution, multiple different types of wire harness fixtures can be provided, thereby enabling the disassembly, replacement, maintenance, and debugging of wire harness fixtures.

[0018] Furthermore, the outer surface of the substrate is connected with a drawing, and the outer surface of the support rod is fixed with a jig head, which is one of the following: U-shaped head, L-shaped head, plastic clip head, three-needle head, hanging hook, and three-pronged branch head.

[0019] By adopting the above technical solution, when the tooling is used, the staff will lay the cables according to the drawings. During this process, various types of jig heads will be used to position and guide the cables. Afterwards, the staff will install components, terminals and other parts according to the assembly information on the drawings, and fix the wire harness with structures such as tape, cable ties and corrugated tubes, thereby completing the assembly of the wire harness.

[0020] Furthermore, a nut is fixed to the outer surface of the support rod, and the strong magnet is detachably connected to the support rod by bolts, and the adsorption block is detachably connected to the substrate by bolts.

[0021] By adopting the above technical solution, when the adsorption block and the strong magnet are damaged, the bolts can be removed to disassemble and replace the adsorption block and the strong magnet.

[0022] Furthermore, the top of the lever has a hexagonal groove, and the bottom of the lever is detachably connected to the insert rod by means of a thread.

[0023] By adopting the above technical solution, when the insert rod is damaged, the lever can be loosened and removed with an Allen wrench, thereby ending the limitation on the insert rod. After that, the insert rod and the spring can be directly removed from the support rod. During assembly, the spring and the insert rod are placed into the support rod in sequence. During this process, the insert rod is pressed to compress and pre-tighten the spring. Then, the operator inserts the lever into the insert rod and tightens it with an Allen wrench, thereby completing the replacement operation.

[0024] Furthermore, the adsorption block is made of galvanized steel.

[0025] By adopting the above technical solution, the factory environment used for wire harness assembly has strict requirements to ensure that the inside of the wire harness is not contaminated or damaged. Therefore, the requirements for corrosion resistance are usually not high. The use of galvanized steel material fully meets the requirements of the usage environment, and the galvanized steel material can be attracted by permanent magnets.

[0026] In summary, the present invention has the following main advantages:

[0027] 1. This utility model uses an adsorption block and a strong magnet. The strong magnet uses magnetic attraction to adhere to the surface of the adsorption block, thereby achieving quick assembly and disassembly. The orientation of the jig head can be adjusted by twisting it with both hands to make the jig head face the wiring direction, which is convenient for subsequent adjustments. It facilitates the disassembly and assembly of the structure and the adjustment of the jig head orientation.

[0028] 2. This utility model, through the arrangement of a plug rod, a lever, a spring, and an adsorption block, allows the strong magnet to attract the adsorption plate while the plug rod, pushed by the spring, penetrates the center of the adsorption block. At this time, the plug rod bears the radial force, preventing the strong magnet from sliding on the plane, while the strong magnet bears the axial force, preventing the support rod from separating from the tooling, thus improving structural stability. When disassembly is required, simply pull the lever to retract the plug rod into the support rod, and then grasp the support rod to apply both radial and axial forces to disassemble it. Compared with axially pulling the support rod for disassembly, this method is more labor-saving and convenient, and improves structural stability.

[0029] 3. This utility model uses a spring with a pre-tight assembly, meaning the spring is compressed once during assembly. Therefore, even if the insertion rod extends from the back of the support rod, the spring can still apply a pushing force to the insertion rod, ensuring its stability. Due to the long stroke of the insertion rod, combined with the continuous force applied by the pre-tight spring, the phenomenon of the insertion rod being affected by vibration and falling out of the adsorption block, thus affecting the stability of the strong magnet, is effectively reduced.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] The embodiments of this utility model will be described below based on its overall structure.

[0038] Example 1:

[0039] An assembly fixture for automotive wiring harnesses, such as Figures 1-5 As shown, the device includes a substrate 1, with an adsorption block 3 embedded on its surface. A strong magnet 4 is connected to the outer surface of the adsorption block 3. Both the strong magnet 4 and the adsorption block 3 are annular. The strong magnet 4 is an N42 neodymium iron boron magnet, and its surface is coated with an epoxy resin layer. The strong magnet 4 is detachably connected to the adsorption block 3. A support rod 5 is connected to the outer surface of the strong magnet 4. An insertion rod 7 passes through the middle of the back of the support rod 5 and is slidably connected to the support rod 5. The insertion rod 7 is detachably connected to the adsorption block 3. A spring 9 connects the insertion rod 7 and the support rod 5. A lever 8 passes through the top of the insertion rod 7. A groove 10 is formed at the top of the support rod 5, and the lever 8 is slidably connected to the groove 10. The adsorption block 3, the strong magnet 4, the support rod 5, the insertion rod 7, the lever 8, the spring 9, and the groove 10 are all... Multiple fixtures are configured. During on-site assembly and debugging before use, the operator pulls lever 8 to retract insert 7 into support rod 5 and compress spring 9. Then, the operator slowly places strong magnet 4 so that it adheres to adsorption block 3. The operator can then release lever 8. When the operator adjusts the fixture position so that strong magnet 4 is fully aligned with adsorption block 3, spring 9 drives lever 8 to pass through adsorption block 3. The operator can then use both hands to forcefully twist and adjust the orientation of fixture head 6 so that it aligns with the wiring direction, facilitating subsequent adjustments. At this time, insert 7 bears radial force to prevent strong magnet 4 from sliding on the plane, while strong magnet 4 bears axial force to prevent support rod 5 from separating from fixture, thus improving structural stability.

[0040] See Figures 1-5 In the above embodiment, the outer surface of the substrate 1 is connected to the drawing 2, and the outer surface of the support rod 5 is fixed with a jig head 6. The jig head 6 is one of the following: U-shaped head, L-shaped head, plastic clip head, three-pin head, wire hook, and three-pronged wire splitter head. When the tooling is used, the operator lays the cable according to the drawing 2. During this process, the cable is positioned and guided by various types of jig heads 6. Then, the operator installs the components, terminals and other parts according to the assembly information on the drawing 2, and fixes the wire harness with structures such as tape, cable ties and corrugated tubes, thereby completing the assembly of the wire harness.

[0041] Example 2:

[0042] Based on the above embodiment one, the following settings are now made for ease of maintenance.

[0043] See Figures 2-5In the above embodiment, a nut is fixed to the outer surface of the support rod 5, the strong magnet 4 is detachably connected to the support rod 5 by bolts, the adsorption block 3 is detachably connected to the base plate 1 by bolts, the top of the lever 8 has a hexagonal groove, and the bottom of the lever 8 is detachably connected to the insertion rod 7 by threads. When the adsorption block 3 and the strong magnet 4 are damaged, the bolts can be removed to disassemble and replace the adsorption block 3 and the strong magnet 4. When the insertion rod 7 is damaged, the lever 8 can be loosened and removed by an Allen wrench, thereby ending the limitation on the insertion rod 7. Then the insertion rod 7 and the spring 9 can be directly removed from the support rod 5. During assembly, the spring 9 and the insertion rod 7 are placed into the support rod 5 in sequence. During this process, the insertion rod is pressed to compress and pre-tighten the spring 9. Then the operator inserts the lever 8 into the insertion rod 7 and tightens it by an Allen wrench to complete the replacement operation.

[0044] Example 3:

[0045] Based on the above embodiment 1, the following settings are made to facilitate the adsorption of the strong magnet 4.

[0046] See Figure 2 and Figure 3 In the above embodiments, the adsorption block 3 is made of galvanized steel. The factory environment used for wire harness assembly has strict requirements to ensure that the inside of the wire harness is not contaminated or damaged. Therefore, the requirements for corrosion resistance are usually not high. The use of galvanized steel fully meets the requirements of the operating environment, and the galvanized steel material can be adsorbed by permanent magnets.

[0047] The implementation principle of this utility model is as follows: First, the base plate 1 is installed on a metal bracket. The metal bracket can be a bracket placed on the ground or a bracket connected to the chain conveyor mechanism and equipped with casters. During production, the fixture head 6 can be a U-shaped head, an L-shaped head, a plastic clip head, a three-needle head, a wire hook, a three-pronged wire splitter head, etc., corresponding to the head of the U-shaped fixture, the head of the L-shaped fixture, the head of the P-shaped fixture, the head of the plastic clip fixture, etc. The difference from the existing fixture is that the rod is not a threaded structure, but a strong magnet 4, a plug rod 7, a lever 8, a spring 9 and a slide groove 10. Furthermore, since the drawings 2 of different wire harnesses are different, the fixture position needs to follow the arrangement of the drawings 2, and different types of fixtures need to be selected according to different scenarios. The tooling is a customized structure, so it is only briefly described in the figure and the instruction manual.

[0048] During on-site assembly and debugging before the tooling is used, the worker pulls lever 8 to retract the insert 7 into the support rod 5 and compress the spring 9. Then, the worker slowly places the strong magnet 4 so that it fits against the adsorption block 3. The worker can then release lever 8. When the worker adjusts the position of the fixture so that the strong magnet 4 is fully aligned with the adsorption block 3, the lever 8 is driven by spring 9 to pass through the adsorption block 3. The worker can then use both hands to forcefully twist and adjust the orientation of the fixture head 6 so that it aligns with the wiring direction, facilitating subsequent adjustments. At this time, the insert 7 bears the radial force to prevent the strong magnet 4 from sliding on the plane, while the strong magnet 4 bears the axial force to prevent the support rod 5 from separating from the tooling, thus improving structural stability.

[0049] When using the tooling, the workers lay out the cables according to drawing 2. During this process, various types of jig heads 6 are used to position and guide the cables. Afterwards, the workers install components, terminals and other parts according to the assembly information on drawing 2, and fix the wire harness with structures such as tape, cable ties and corrugated tubing, thereby completing the assembly of the wire harness. The specific process flow varies depending on the different models of wire harnesses, so this technical solution only describes the general process.

[0050] When the fixture needs to be replaced during subsequent maintenance, or when drawing 2 needs to be replaced, the operator can pull the lever 8 to retract the insert 7 into the support rod 5. Then, the operator can grasp the support rod 5 and apply both radial and axial forces to disassemble it. Compared with axially pulling the support rod 5, this method is more labor-saving and convenient, making it easier to remove the damaged fixture or to recycle the fixture for the next drawing 2.

[0051] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
