Description

Technical Field

[0001] This utility model relates to the field of wire harness assembly technology, and in particular to an adaptive clamp, wire harness carrier and wire harness assembly equipment based on wire core separation. Background Technology

[0002] In the assembly and production of multi-core wire harnesses, one end typically needs to be stripped to expose the internal core wires. The processed harness is then transferred to the next process for subsequent processing such as number tube sheathing, secondary stripping, or crimping terminals. However, existing technologies suffer from the following prominent problems: After stripping, the unseparated core wires are often in a disordered state. This disordered arrangement not only makes the core wires prone to tangling or misalignment during transport but also significantly increases the difficulty of core wire positioning and organization when switching to the next processing step. Especially in automated production scenarios, loose multi-strand core wires can easily interfere with the gripping action of robotic arms, causing poor process transitions. Furthermore, traditional fixed clamps are difficult to adapt to the clamping requirements of core wires with different diameters. Insufficient clamping force can lead to core wire displacement, while excessive clamping may damage the wire insulation layer. These problems severely restrict the production efficiency and quality stability of wire harness assembly. Utility Model Content

[0027] Reference Figures 1 to 3This utility model embodiment provides an adaptive clamp 1 based on core separation.

[0028] like Figure 1 and Figure 2 As shown, the adaptive clamp 1 includes a fixed base 100 and a clamping mechanism. The fixed base 100 has a receiving cavity, and the clamping mechanisms are disposed within the receiving cavity. Multiple clamping mechanisms are arranged at equal intervals along the radial direction of the receiving cavity. Each clamping mechanism includes a first clamping block 200 and a second clamping block 300. The first clamping block 200 is fixedly connected to the fixed base 100, and the second clamping block 300 is movably connected to the fixed base 100. The first clamping block 200 and the second clamping block 300 are arranged opposite to each other to form a clamping cavity 11. The second clamping block 300 can move away from or closer to the first clamping block 200 to adjust the opening range of the clamping cavity 11.

[0029] Understandably, when the core wire 3 enters the clamping cavity 11, the second clamping block 300 moves outward under external force, and the opening of the clamping cavity 11 expands to accommodate the wire diameter. After the external force is removed, the movable connecting mechanism resets the second clamping block 300, forming a stable clamp together with the fixed first clamping block 200. The radially arranged clamping mechanism forms multiple independent clamping points, and the spacing between adjacent clamping points is ensured by equidistant arrangement, keeping the core wire 3 parallel during separation. Among them, the fixed first clamping block 200 serves as a unified reference plane to eliminate the positioning error of the split clamp, and the movable second clamping block 300 compensates for the wire diameter tolerance through displacement, avoiding wire damage caused by rigid clamping.

[0030] This application achieves dynamic adjustment while maintaining a unified reference by combining fixed and movable clamping blocks. The radially equidistant layout ensures synchronized action of each clamping point, preventing core wire twisting and enabling automatic separation and stable clamping of multi-core wire bundles. The dynamic adjustment function of the movable clamping blocks is compatible with core wires of different diameters, eliminating the need for manual adjustment of clamp spacing. The cooperation between the fixed and movable clamping blocks forms a self-centering clamping structure, ensuring that the core wires remain parallel after separation. Furthermore, the radially equidistant clamping mechanism provides a precise positioning reference for subsequent processes.

[0031] Specifically, such as Figures 1 to 3 As shown, the second clamping block 300 includes a clamping portion 310, and a clamping cavity 11 for clamping the core wire 3 is formed between the clamping portion 310 and the first clamping block 200. Further, the second clamping block 300 and the fixing base 100 are hinged together by a hinge structure. Specifically, the hinge structure includes a hinge hole provided on the second clamping block 300 and a hinge shaft provided on the fixing base 100.

[0032] Understandably, the second clamping block 300 forms a rotating pair through the clearance fit between the hinge shaft and the hinge hole, causing the clamping part 310 to undergo linear displacement changes during rotation around the axis, thereby adjusting the opening width of the clamping cavity 11. When an external force is applied to the second clamping block 300, the frictional force generated between the inner wall of the hinge hole and the contact surface of the hinge shaft creates a self-locking effect, preventing the clamping cavity 11 from accidentally expanding in the absence of external force.

[0033] Preferably, the clamping part 310 and the second clamping block 300 are manufactured using an integrated molding process to ensure that they maintain structural rigidity during repeated opening and closing actions and avoid deformation problems caused by stress concentration.

[0034] As a further improvement to the plan, such as Figure 2 As shown, a telescopic member 400 is provided between the second clamping block 300 and the fixed base 100. It can be understood that the telescopic member 400 in this application refers to an elastic element with axial telescopic function, specifically implemented as a spring or pneumatic telescopic rod. Its two ends are connected to the movable clamping block and the fixed component respectively, generating a continuous retraction force through elastic deformation. That is, when the second clamping block 300 is opened by an external force, the telescopic member 400 undergoes tensile deformation, storing elastic potential energy; after the external force disappears, the elastic restoring force drives the second clamping block 300 to return to its original position towards the first clamping block 200, thereby maintaining the continuous clamping pressure of the clamping cavity 11 on the wire core.

[0035] Preferably, the retractable component 400 of this application is a spring, specifically a helical spring or a disc spring. The compression or stretching of the spring generates an elastic restoring force, enabling the second clamping block 300 to automatically adapt to changes in the core size.

[0036] In some other embodiments of this application, a hinge spring is provided between the hinge hole and the hinge shaft. It can be understood that the hinge spring in this application refers to a rotational elastic element installed inside the hinge pair, specifically a torsion spring or a coil spring. It is sleeved on the hinge shaft and forms a torque transmission relationship with the hinge hole, generating a rotational torque that causes the clamping block to close through elastic deformation. That is, when the second clamping block 300 rotates around the hinge shaft, it forces the hinge spring to undergo torsional deformation, and the reverse torque generated by the spring causes the clamping block to automatically return to the closed position without external force.

[0037] The advantage is that the application utilizes the dynamic balancing effect of the elastic element to ensure that the clamping cavity 11 maintains a stable clamping state on the wire core even when subjected to vibration or external force interference during the transfer process. This achieves adaptive adjustment of the opening and closing range of the clamping cavity 11, continuously applying elastic clamping force during the transfer process to prevent the wire core from shifting or scattering due to loose clamping, ensuring that the wire core maintains a predetermined arrangement in subsequent processes, thereby improving the processing efficiency of processes such as sleeve and terminal crimping.

[0038] As a further improvement to the solution, the adaptive clamp 1 provided in this application is also provided with an adjustment drive (not shown in the figure). Specifically, the adjustment drive (not shown in the figure) is fixed on the fixed base 100, and the output end of the adjustment drive (not shown in the figure) is connected to the second clamping block 300. The adjustment drive (not shown in the figure) can drive the second clamping block 300 to rotate, so as to adjust the clamping force of the clamping cavity 11 on the workpiece.

[0039] Understandably, when the wire core enters the clamping cavity 11, the elastic force of the spring pushes the second clamping block 300 to move towards the first clamping block 200, forming a basic clamping force. The output end of the adjusting drive (not shown) is connected to the second clamping block 300 through a connecting mechanism. When it is necessary to adjust the clamping force, the adjusting drive (not shown) drives the second clamping block 300 to rotate around the hinge axis, changing the closing angle of the clamping cavity 11, thereby actively increasing or decreasing the clamping pressure on the core wire 3. The passive adjustment mechanism of the spring and the active control mechanism of the adjusting drive (not shown) form a combined effect, enabling the clamping force to both adapt to fluctuations in the core wire size and be precisely adjusted according to process requirements.

[0040] The adaptive clamp 1 provided in this application, through the synergistic action of a spring and an adjusting drive (not shown in the figure), achieves dynamic adjustment of the clamping force while maintaining basic clamping stability. It can adjust the clamping pressure in real time during the core clamping process, preventing core deformation or insulation damage due to excessive clamping force, while also preventing core slippage caused by insufficient clamping force. For cores of different diameters or materials, the optimal clamping force can be quickly matched by adjusting the drive (not shown in the figure), ensuring clamping stability during the core separation process while reducing the risk of damage. This overcomes the shortcomings of uncontrollable clamping force from a single elastic element or lag in response from a single drive device.

[0041] Preferably, the adjustment drive (not shown) can be a cylinder.

[0042] According to some embodiments of this application, the adaptive clamp 1 provided in this application is further provided with a first limiting structure to limit the opening range of the clamping cavity 11 and constrain the rotation path of the second clamping block 300.

[0043] like Figure 2 As shown, specifically, the first limiting structure includes a first limiting part 210 disposed on the first clamping block 200 and a second limiting part 320 disposed on the second clamping block 300, wherein the first clamping block 200 is provided with a first curved surface to form the first limiting part 210, and the second clamping block 300 is provided with a second curved surface to form the second limiting part 320.

[0044] In some embodiments of this application, the first surface is a convex surface and the second surface is a concave surface.

[0045] Understandably, the first limiting structure constrains the rotation trajectory of the second clamping block 300 through the engagement of concave and convex curved surfaces. When the second clamping block 300 is displaced by an external force, sliding friction occurs between the contact surfaces of the second limiting part 320 and the first limiting part 210, forcing the second clamping block 300 to move along a preset arc trajectory. During this process, the abutment action of the first limiting part 210 against the second limiting part 320 forms a mechanical limit, preventing the second clamping block 300 from shifting laterally due to inertia or external vibration. Simultaneously, the elastic tendency force applied by the second limiting part 320 against the first limiting part 210 ensures that the telescopic member 400 is always subject to a reverse constraint during extension and retraction, thereby limiting the opening range of the clamping cavity 11 within a controllable range. For example, when the clamping cavity 11 needs to be expanded to accommodate wire cores of different diameters, the rotation angle of the second clamping block 300 is precisely limited by the curved surface contact relationship between the first limiting part 210 and the second limiting part 320, avoiding a sudden drop in clamping force due to excessive opening.

[0046] This application establishes a bidirectional motion constraint through the rigid contact between the first limiting part 210 and the second limiting part 320. This synchronously corrects the displacement trajectory of the clamping block during the driving process of the telescopic component 400, improving the linearity of the clamping action and suppressing unexpected displacement of the clamping mechanism during adaptive adjustment. This ensures consistent symmetrical opening and closing of each clamping cavity 11 during core separation. Under conditions of clamping cores of different diameters, the limiting structure maintains a uniform distribution of clamping force, preventing core slippage or twisting deformation caused by excessive deflection of one side of the clamping block, thereby improving the accuracy and reliability of core wire separation during wire harness assembly.

[0047] As a further improvement to the plan, such as Figure 1 and Figure 2 As shown, a limiting cavity 12 is formed between two adjacent first clamping blocks 200. The clamping part 310 is located within the limiting cavity 12, which further constrains the range of motion of the clamping cavity 11. It can be understood that the limiting cavity 12 refers to a semi-enclosed space formed between the side walls of two adjacent first clamping blocks 200. The distance between the side walls of the two first clamping blocks 200 is a fixed value, which determines the maximum expansion range of the clamping cavity 11. The movement of the clamping part 310 is restricted within the boundary range of the limiting cavity 12, thus limiting the displacement of the clamping component to a predetermined range. When the second clamping block 300 moves outward, the clamping part 310 stops moving after contacting the side wall of the adjacent first clamping block 200.

[0048] That is, when the second clamping block 300 rotates outward under the action of an external force, the clamping part 310 moves synchronously with the second clamping block 300 until the outer surface of the clamping part 310 contacts the side wall of the adjacent first clamping block 200. At this time, the side wall of the limiting cavity 12 forms a rigid barrier, preventing the second clamping block 300 from continuing to rotate outward, so that the opening width of the clamping cavity 11 is forcibly limited within a set threshold. In this process, the cooperation between the clamping part 310 and the limiting cavity 12 forms a multiple limiting mechanism: on the one hand, the clamping width is limited by the rotation angle of the hinge structure, and on the other hand, secondary limiting is achieved by the contact of the side wall of the limiting cavity 12.

[0049] This application utilizes a limiting cavity 12 structure formed by adjacent clamping blocks to construct a physical barrier boundary within the clamping mechanism. This eliminates the need for additional limiting components, enabling precise control of the clamping amplitude and effectively preventing wire core slippage caused by excessive opening of the clamping cavity 11 during wire core transfer. This ensures stable clamping of wire cores of different diameters. The limiting cavity 12 structure automatically triggers its limiting function when the clamping mechanism operates, maintaining consistent clamping amplitude without manual intervention, thereby ensuring the stability of the wire core separation state in subsequent processes.

[0050] According to some embodiments of this application, the clamping structure for clamping the core wire 3 consists of a first clamping surface 220 disposed on the first clamping block 200 and a second clamping surface 330 disposed on the second clamping block 300.

[0051] Among them, such as Figure 3 As shown, the second clamping surface 330 is provided with a slot 331, which improves the clamping stability of the clamping structure on the workpiece. Alternatively, in some other embodiments of this application, the first clamping surface 220 is also provided with a slot 331.

[0052] It is understandable that the first clamping surface 220 refers to the pressure-bearing area on the fixed clamping block used for contacting the wire core, the second clamping surface 330 refers to the pressure-bearing area on the movable clamping block opposite to the first clamping surface 220, and the slot 331 refers to the recessed structure set on the clamping surface, which can be implemented by using a V-shaped slot, a U-shaped slot or a sawtooth slot. Its function is to constrain the displacement of the wire core through local deformation and enhance the mechanical interlocking effect.

[0053] That is, when the wire core is clamped in the clamping cavity 11, the first clamping surface 220 and the second clamping surface 330 form multi-point contact with the surface of the wire core through the slot 331. For example, when the slot 331 is only provided on the first clamping surface 220, the wire core is pressed into the slot and undergoes local deformation, thereby limiting its sliding along the clamping direction; when both clamping surfaces are provided with slots 331, the wire core is simultaneously embedded in the symmetrical slots on both sides, forming a bidirectional interlocking structure, which can accommodate wire cores of different diameters. For example, wire cores with smaller diameters can fall into the bottom of the slot 331 for stable clamping, while wire cores with larger diameters generate greater contact pressure through the inclined surface of the slot edge.

[0054] Optionally, the surfaces of the first clamping surface 220 and the second clamping surface 330 are both knurled or have anti-slip textures added, which increases the coefficient of friction with the wire core.

[0055] This application transforms the clamping method of the wire core from surface contact to partial line contact or point contact by setting a slot 331 on the clamping surface. This significantly increases the pressure per unit area under the same clamping force. At the same time, the slot structure provides geometric restraint for the core wire 3, effectively suppressing lateral displacement and solving the problem of wire core displacement caused by insufficient friction on the clamping surface. The slot 331 structure enhances the mechanical interlocking effect, ensuring that the wire core maintains a stable posture during transportation and processing, avoiding process interruptions caused by loosening, thereby improving the assembly efficiency of multi-core wire bundles 3.

[0056] According to some embodiments of this application, the bottom of the clamping cavity 11 is provided with an anti-drop structure. Specifically, as shown in the figure... Figure 2 As shown, the anti-drop structure includes a first abutting part 230 on the first clamping block 200 and a second abutting part 340 on the second clamping block 300. The two abutting parts contact each other during the clamping action to form a closed support surface.

[0057] It is understandable that the anti-drop structure refers to the blocking structure located below the opening of the clamping cavity 11, which is used to constrain the longitudinal displacement of the wire core in the clamping state.

[0058] Specifically, the first abutment portion 230 refers to a protruding structure integrally formed with the first clamping block 200. Its surface can be processed into a flat or curved surface to provide basic support, maintain a fixed position during clamping, and form a reference surface to prevent falling. The second abutment portion 340 refers to a protruding structure integrally formed with the second clamping block 300. Its surface can be processed into a flat or curved surface. During clamping, it always abuts against the first abutment portion 230 to form a support structure for the core wire 3 when it is clamped, so as to prevent the core wire 3 from falling between the first clamping block 200 and the second clamping block 300 due to clamping force.

[0059] This application enables the formation of a bottom physical limit during the core clamping process, preventing accidental detachment due to clamp vibration, the weight of the core 3, or excessive clamping force. The anti-drop function is automatically triggered by the clamping action, avoiding the complexity introduced by manual intervention or additional drive components, ensuring the core remains stably clamped during transport and processing, thereby improving the efficiency of subsequent processes.

[0060] As a further improvement to the plan, such as Figure 3 As shown, a second limiting structure is provided between the first clamping block 200 and the second clamping block 300. Specifically, the second limiting structure includes a third limiting part 240 provided on the first clamping block 200 and a fourth limiting part 350 provided on the second clamping block 300. When the first clamping block 200 rotates, the third limiting part 240 can move away from or closer to the fourth limiting part 350.

[0061] It is understood that the third limiting part 240 refers to a physical limiting component provided on the first clamping block 200, which can be implemented using a protrusion or groove structure. The fourth limiting part 350 refers to a corresponding limiting component provided on the second clamping block 300, which can be implemented using a groove or protrusion structure with a shape complementary to the third limiting part 240. The second limiting structure refers to a rigid limiting assembly composed of the third limiting part 240 and the fourth limiting part 350, which achieves mechanical constraint on the range of motion through the contact surface between the two.

[0062] That is, when the first clamping block 200 rotates relative to the second clamping block 300, the relative position between the third limiting part 240 and the fourth limiting part 350 changes. During the rotation, the contact surfaces between the third limiting part 240 and the fourth limiting part 350 gradually move closer or further apart. When they come into contact, they form a rigid stop, which, in conjunction with the limiting cavity 12, further restricts the opening range of the clamping cavity 11.

[0063] This application achieves precise control of the opening and closing amplitude of the clamping cavity 11 by using the dynamic coordination of the rigid limiting structure, while maintaining the adaptive adjustment capability and using the geometric relationship of the contact surface to precisely control the range of motion, preventing structural damage caused by excessive rotation of the clamping block. This avoids the problem of wire core falling off or insufficient clamping force caused by excessive displacement of the clamping block during the clamping process.

[0064] As a further improvement to the plan, such as Figure 2 As shown, a guide structure is provided at the opening of the clamping cavity 11. Specifically, the guide structure includes a guide portion 250 provided on the first clamping block 200. Preferably, the guide portion 250 is an inclined surface or an arc-shaped surface provided on the end of the first clamping block 200, so as to guide the core wire 3 to accurately enter the clamping cavity 11.

[0065] Optionally, the end of the second clamping block 300 may also be provided with the same inclined or arc-shaped surface to form a guide portion 250.

[0066] like Figure 4 As shown, this application also provides a wire harness carrier 2, which applies the aforementioned adaptive clamp 1.

[0067] Furthermore, this application also provides a wire harness assembly device that uses the wire harness carrier 2 described above or only uses the adaptive clamp 1 described above.

[0068] The adaptive clamp 1 provided in this application can stably clamp multiple core wires 3 of a wire harness simultaneously during wire harness assembly production. Furthermore, the core wires 3 are spaced equally, effectively avoiding repetitive positioning in subsequent processing steps. The displacement of the movable second clamping block 300 compensates for differences in wire diameter, while maintaining the fixed first clamping block 200 as a unified reference plane. The movable second clamping block 300 and the fixed first clamping block 200 form a dynamic clamping pair, achieving flexible adjustment while maintaining a fixed reference, thus balancing positioning accuracy and adaptability.
