Description

Technical Field

[0001] This utility model relates to the technical field of wire harness processing, and in particular to an auxiliary positioning device for wire harness processing. Background Technology

[0002] Automotive wiring harnesses are the core of a vehicle's electrical network; without them, there is no automotive electrical system. A wiring harness is an assembly consisting of copper-plated contact terminals (connectors) crimped to wires and cables, then covered with a molded insulator or an outer metal shell, and bundled together to form a connected circuit. The wiring harness industry chain includes wires and cables, connectors, processing equipment, wiring harness manufacturing, and downstream applications. Wiring harnesses have a wide range of applications, including automobiles, home appliances, computer and communication equipment, and various electronic instruments. Body wiring harnesses connect the entire vehicle body and are generally H-shaped. With the increasing functionality of automobiles and the widespread application of electronic control technology, there are more and more electrical components, resulting in more and more wires, and consequently, thicker and heavier wiring harnesses. Therefore, advanced automobiles have introduced CAN bus configurations, employing multiplexed transmission systems. Compared to traditional wiring harnesses, multi-path wiring devices significantly reduce the number of wires and connectors, simplifying wiring. Automotive wiring harnesses are a crucial component of automobiles, and during production, they require precise positioning to ensure quality meets the requirements of various vehicles. After technicians at the wiring harness factory create wiring harness boards based on the wiring harness diagrams, workers cut and lay wires according to the specifications on the boards. The main wiring harness of a vehicle is generally divided into engine (ignition, electronic fuel injection, generator, starter), instrument panel, lighting, air conditioning, and auxiliary electrical components, consisting of main and branch harnesses. A main vehicle wiring harness has multiple branch harnesses, much like the trunk and branches of a tree. The main vehicle wiring harness often extends forward and backward, with the instrument panel as its core. Due to length constraints or ease of assembly, some automotive wiring harnesses are divided into front harnesses (including instrument panel, engine, front lighting assembly, air conditioning, and battery) and rear harnesses (taillight assembly, license plate light, and trunk light).

[0003] According to the specification of Chinese Utility Model Publication No. CN219426628U, "An auxiliary positioning device for wire harness processing includes a base plate. The top surface of the base plate is provided with two left-right symmetrical main blocks. A screw is threaded into the top surface of the main blocks. A pressure plate is movably sleeved on the surface of the screw. The two main blocks can position and fix the two ends of the wire harness through the cooperation between the pressure plate and the screw. The top surface of the base plate between the two main blocks is provided with two left-right symmetrical sub-blocks. The top surface of the sub-blocks is provided with grooves. Two clamping plates that can move relative to each other are provided in the grooves. The two clamping plates can provide auxiliary positioning and fixation for the wire harness."

[0004] As can be seen from the aforementioned patent, in the current automotive wiring harness manufacturing process, the wiring harness is mostly fixed at both ends. Although this fixing method can meet the basic positioning and reinforcement of the wiring harness, it cannot stably fix each part of the wiring harness, which may cause the wiring harness to shake significantly during the manufacturing process, affecting the normal progress of the wiring harness manufacturing. Therefore, two sets of clamps are set for limiting the position. However, this device requires clamping the wiring harness during use, which is inconvenient to operate and affects the work efficiency. Utility Model Content

[0005] 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.

[0006] The technical solution adopted in this utility model is:

[0007] An auxiliary positioning device for wire harness processing includes a limiting assembly: the limiting assembly includes; a frame symmetrically arranged on the top of a worktable; a fixing plate disposed on the inner side of the frame; a lead screw disposed on the top of the fixing plate and threadedly connected to the fixing plate; a pressure plate rotatably disposed on the bottom of the lead screw; support blocks symmetrically arranged on the top of the worktable; arc-shaped grooves respectively opened on the top of the support blocks and the inner side of the frame; a support rod disposed on the top of the worktable; a spring sleeved on the outer side of the support rod; a connecting plate disposed on the top of the support rod; a through groove opened on the top of the connecting plate; a nut sleeved on the outer side of the support rod and threadedly connected to the support rod; pressure rods symmetrically arranged on the connecting plate; and a wire harness disposed on the inner side of the arc-shaped groove.

[0008] Optionally, the pressure bar is provided with an auxiliary component, the auxiliary component including: a rubber ring sleeved on the outside of the pressure bar.

[0009] Optionally, the auxiliary component further includes a sleeve disposed on the top of the worktable.

[0010] Optionally, the pressure rod and the connecting plate are threaded together.

[0011] Optionally, the auxiliary component further includes a cone disposed at the top of the support rod.

[0012] Optionally, the auxiliary component further includes a sponge pad disposed on the inner side of the arc-shaped groove.

[0013] Optionally, the auxiliary component further includes a stop lever disposed on the top of the support block.

[0014] Optionally, the stop lever is a screw.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] When it is necessary to limit and fix the wire harness, first place the wire harness inside the arc-shaped groove on the top of the support block, then place both ends of the wire harness inside the frame. Next, rotate the lead screw. Since the lead screw is threadedly connected to the fixing plate and has a pressure plate rotatably connected to its bottom, it can drive the pressure plate down to squeeze and fix both ends of the wire harness. After completion, rotate the connecting plate to move the two sets of pressure rods on one side of the connecting plate to the top of the support block, and then press down the pressure rods to squeeze and fix the wire harness. Then rotate the nut to fix the connecting plate, thereby fixing the wire harness. This can prevent the wire harness from shaking significantly during processing. After subsequent processing, simply rotate the nut to release the fixing of the connecting plate, then rotate the connecting plate to rotate the pressure rods to the outside of the equipment. This allows the operator to remove the wire harness. The device has a simple structure, making it easy to fix or disassemble the wire harness, making it more convenient to use and increasing work efficiency. Attached Figure Description

[0023] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Given that in the current technology, most existing automotive wiring harnesses are fixed by fixing both ends during processing, although this method can meet the basic positioning and reinforcement needs, it cannot stably fix every part of the wiring harness. This can lead to significant shaking of the wiring harness during processing, affecting the normal progress of the wiring harness processing. Therefore, two sets of clamps are set up for limiting the movement. However, this device requires clamping the wiring harness during use, which is inconvenient and affects work efficiency.

[0025] like Figure 1-2 As shown, this utility model embodiment provides an auxiliary positioning device for wire harness processing, including a limiting component 1: the limiting component 1 includes: a frame 12 symmetrically arranged on the top of a worktable 11; a fixing plate 121 disposed on the inner side of the frame 12; a lead screw 13 disposed on the top of the fixing plate 121 and threadedly connected to the fixing plate 121; a pressure plate 131 rotatably disposed on the bottom of the lead screw 13; support blocks 14 symmetrically arranged on the top of the worktable 11; and arc-shaped grooves 15 respectively... A support rod 16 is located on the top of the support block 14 and the inner side of the frame 12; a spring 161 is sleeved on the outer side of the support rod 16; a connecting plate 17 is located on the top of the support rod 16; a through groove 171 is opened on the top of the connecting plate 17; a nut 18 is sleeved on the outer side of the support rod 16 and threadedly connected to the support rod 16; pressure rods 181 are symmetrically arranged on the connecting plate 17; and a wire harness 19 is located on the inner side of the arc-shaped groove 15.

[0026] When it is necessary to limit and fix the wire harness 19, first place the wire harness inside the arc-shaped groove 15 opened at the top of the support block 14, then place both ends of the wire harness 19 inside the frame 12, and then rotate the lead screw 13. Since the lead screw 13 is threadedly connected to the fixing plate 121 and the pressure plate 131 is rotatably connected to its bottom, the pressure plate 131 can be driven to press down to squeeze and fix both ends of the wire harness 19. After completion, rotate the connecting plate 17 to move the two sets of pressure rods 181 on one side of the connecting plate 17 to directly above the support block 14, and then press down the pressure rods 181. The wire harness 19 is pressed and fixed, and then the nut 18 is rotated to fix the connecting plate 17, thereby fixing the wire harness 19. This can prevent the wire harness 19 from shaking significantly during processing. After subsequent processing, simply rotate the nut 18 to release the fixing of the connecting plate 17, and then rotate the connecting plate 17 to rotate the pressure rod 181 to the outside of the equipment. This allows the operator to pick up the wire harness 19. The device has a simple structure, which facilitates the fixing or disassembly of the wire harness 19, making it more convenient to use and increasing work efficiency.

[0027] Furthermore, an auxiliary component 2 is provided on the pressure rod 181, the auxiliary component 2 including a rubber ring 21 sleeved on the outside of the pressure rod 181.

[0028] A rubber ring 21 is fitted on the outer wall of the pressure rod 181. When the pressure rod 181 presses and fixes the wire harness 19, the rubber ring 21 can increase the friction between the pressure rod 181 and the wire harness 19, thereby increasing the fixing effect of the wire harness 19 and avoiding indentations on the surface of the wire harness 19.

[0029] Furthermore, the auxiliary component 2 also includes a sleeve 22 disposed on the top of the worktable 11.

[0030] A sleeve 22 is installed on the top of the workbench 11 to cover the spring 161. This prevents the spring 161 from being exposed, protects the spring 161, increases its service life, and enhances the aesthetics of the device.

[0031] Furthermore, the pressure rod 181 is threadedly connected to the connecting plate 17.

[0032] The pressure rod 181 and the connecting plate 17 are connected by a thread. This way, if the pressure rod 181 is damaged or deformed in the future, it can be removed and replaced by screwing, so as not to affect the limiting of the wire harness 19 in the future.

[0033] Furthermore, the auxiliary component 2 also includes a cone 23 disposed at the top of the support rod 16.

[0034] A cone 23 is provided at the top of the support rod 16. This allows the support rod 16 to be connected to the through groove 171 more easily and quickly by using the shape of the cone 23.

[0035] Furthermore, the auxiliary component 2 also includes a sponge pad 24 disposed on the inner side of the arc-shaped groove 15.

[0036] A sponge pad 24 is provided on the inner side of the arc groove 15 to protect the wire harness 19 placed inside the arc groove 15 and prevent scratches from being caused to the surface of the wire harness 19.

[0037] Furthermore, the auxiliary component 2 also includes a stop lever 25 disposed on the top of the support block 14.

[0038] A stop bar 25 is provided on the top of the support block 14 on one side. This can limit the pressure bar 181 on one side through the stop bar 25, making it easier to reset the stop bar 25 later, making it more convenient to use.

[0039] Furthermore, the stop lever 25 is a screw.

[0040] The stop lever 25 is set as a screw and threadedly connected to the support block 14. This allows the stop lever 25 to be disassembled by screwing, so that the damaged stop lever 25 can be replaced, thus avoiding affecting the reset of the pressure rod 181.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
