Description

Technical Field

[0001] The present invention relates to the technical field of automotive wire harness processing, and particularly to an automotive wire harness cutting device and method with an automatic clamping function. Background Art

[0002] As an object for transmitting internal signals of an automobile, an automotive wire harness needs to go through multiple steps during the processing, including the cutting step of the automotive wire harness; For example, in the patent of an automotive wire harness cutting device for automotive wire harness production with the publication number CN218744594U, including a bottom plate, a first connecting plate is fixedly connected to the left side of the top of the bottom plate. First, through the setting of a driving motor, the rotating rod is driven to rotate. The rotating rod rotates in cooperation with a first gear, a threaded rod, and a second gear. The threaded rod drives a threaded sleeve, a connecting rod, a housing, a second support plate, a connecting block, a fixing plate, and a blade to move downward, solving the problem that the existing wire harness cutting device does not have a buffering function, and it is easy to cause damage to the blade during the process of cutting the automotive wire harness by the blade, resulting in the blade being unable to cut the wire harness completely, thus affecting the working efficiency and greatly reducing the production efficiency and quality. Another example is the patent of a cutting device for automotive wire harness production with the publication number CN222020581U. A limiting component is arranged at the upper left end of the workbench for limiting and fixing the automotive wire harness. A support frame is arranged on the right side of the limiting component. A cutting component is arranged at the lower left end of the transmission component for cutting the automotive wire harness. A chute is opened on the right inner wall of the workbench. A falling hole is opened through the upper wall of the chute. A collecting component is arranged inside the chute for collecting and classifying the wire harness. A correcting plate is arranged on the right side of the falling hole. The bottom end of the correcting plate is fixedly connected to the upper wall of the workbench; In the technical field of an automotive wire harness cutting device for automotive wire harness production with the publication number CN220278148U, an automotive wire harness cutting device for automotive wire harness production is proposed, including a cutting machine. The cutting machine is located in the middle of the device. A conveying table is arranged at the bottom end of the cutting machine. The front and rear ends of the middle part of the conveying table are fixedly connected to the bottom end of the cutting machine. The conveying table is located on the left and right sides of the bottom end of the cutting machine. A storage tank is fixedly connected to the right side of the conveying table. The storage tank is in a rectangular shape as a whole. The storage tank is located on the left side of the device. By providing a grid fence and a conveying device, materials are sent to the lower part of the cutting device through multiple lines, avoiding the problem that only one wire harness can be processed each time, and the grid fence arranges the materials, so there is no need to worry about problems such as overlapping or inclined cuts, improving the production efficiency and the usage efficiency of the device; Most of the above-mentioned prior arts have improved their overall structures. However, the existing automobile wire harness cutting devices need auxiliary positioning processing during the working process due to the relatively round shape of the wire harness. Most of them are positioned through cumbersome manual operations in conjunction with mechanical structures. They cannot stably and quickly perform automatic two-way clamping work to ensure their cutting accuracy and stability, and thus have certain usage limitations. Summary of the invention

[0003] The purpose of the present invention is to provide an automobile wire harness cutting device and method with an automatic clamping function, so as to solve the problem raised in the above background technology that due to the relatively round shape of the wire harness, it needs auxiliary positioning processing during the cutting process, and most of the positioning work is carried out through cumbersome manual operation and mechanical structure, and it is impossible to stably and quickly perform automatic two-way clamping work to ensure its cutting accuracy and stability.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automobile wire harness cutting device and method with an automatic clamping function, comprising a preset lower base, a preset upper base is nested on the upper end of the preset lower base, and reserved cutting components are respectively installed between the preset upper base and the preset upper base for cutting the wire harness; a built-in supporting liquid capsule is adhesively connected to the lower end of the outer side of the preset upper base, and the built-in supporting liquid capsule is arranged on the inner side of the outer end of the preset lower base, a first return spring is arranged on the outer side of the built-in supporting liquid capsule, and the first return spring is butt-jointed with the inner side of the preset lower base, a reserved steel wire rope is butt-jointed at the upper end of the preset lower base, and an auxiliary guiding structure is arranged on the inner side of the preset lower base, and the limit range of the reserved steel wire rope is controlled by the auxiliary guiding structure.

[0005] Furthermore, the auxiliary guide structure is provided with a supply through tube, and the supply through tube is connected to the inside of the lower end of the built-in support liquid capsule, and the supply through tube passes through the inner side of the preset lower base, and a vertical guide groove is opened on the inner side of the preset lower base, and the upper end of the vertical guide groove is connected to an external support liquid capsule, and the external support liquid capsule and the supply through tube are connected to each other.

[0006] Furthermore, the lower end of the external supporting liquid bag is docked with a resistance docking piece, and the resistance docking piece is arranged on the inner side of the vertical guide groove, the upper end of the resistance docking piece is docked with a movable traction piece, and the movable traction piece and the outer side of the reserved steel wire rope are docked with each other; the outer side of the reserved steel wire rope is docked with a reserved guide rod, and the reserved guide rod is arranged on the inner side of the preset lower base, and a torsion spring is docked between the reserved steel wire rope and the reserved guide rod.

[0007] Further, the reserved cutting assembly forms a vertical moving structure along the inner side of the preset lower base through the built-in support liquid sac and the first reset spring. The built-in support liquid sac is pressurized to supply the inside of the external support liquid sac through the supply pipe, and the external support liquid sac expands to push the contact docking part downward.

[0008] Further, the contact docking part and the movable traction part are of an integrated structure. The movable traction part moves downward synchronously with the downward movement of the contact docking part, and the movable traction part drives the reserved steel wire rope to move downward and deform along the inner side of the preset lower base.

[0009] Further, an auxiliary limiting structure is arranged inside the preset lower base to perform horizontal positioning processing on the contacted wire harness. The auxiliary limiting structure is provided with a horizontal guiding groove, and the horizontal guiding groove is opened on the inner side of the preset lower base. An movable positioning part is nested and installed on the inner side of the preset lower base, and a second reset spring is fixedly connected to the outer side of the movable positioning part, and the second reset spring is mutually docked with the inner side of the horizontal guiding groove.

[0010] Further, the movable positioning part is in an "L" shape when viewed from the front. When the lower end of the movable positioning part contacts the downward moving contact docking part, it is synchronously pressurized, and the contact docking part forms a horizontal sliding structure along the inner side of the horizontal guiding groove through the second reset spring.

[0011] Further, the movable positioning parts are symmetrically distributed about the center point of the preset lower base, and two movable positioning parts are arranged facing each other, and the movable positioning parts cooperate with the reserved steel wire rope to perform multi-directional positioning processing on the contacted wire harness.

[0012] An automobile wire harness cutting device with an automatic clamping function also discloses a cutting method for the automobile wire harness cutting device. The specific method steps are as follows: S1: Place the automobile wire harness to be cut through its inner side. Under the condition of finger pressure, the wire harness can be cut by the reserved cutting components distributed in an alternating manner at its inner end. With the cooperation of the auxiliary guiding structure, there is no need to perform positioning work by cumbersome manual operation and mechanical structure during the cutting process; S2: As the outer end of the preset upper base moves downward, it will contact and press the built-in support liquid sac. Thus, through pressure, it supplies the inside of the external support liquid sac through the supply pipe. The external support liquid sac expands to push the contact docking part, and drives the reserved steel wire rope to move downward and deform along the inner side of the preset lower base through the movable traction part, thereby performing adaptive locking processing on the contacted wire harness; S3: During the process that the abutting and docking member moves downward along the inner side of the preset lower base under force, it will press on the contacting "L"-shaped movable positioning member through the outer inclined surface-like structure, and cooperate with the oppositely arranged movable positioning members to stably synchronously position the lower end of the contacting wire harness, and cooperate with the reserved steel wire rope for linear positioning to perform multi-directional locking treatment on the contacting wire harness.

[0013] Compared with the prior art, the beneficial effects of the present invention are: The automobile wire harness cutting device and method with an automatic clamping function are provided with an auxiliary guiding structure to control the limiting range of the reserved steel wire rope. After the user holds the finger sleeve between the preset lower base and the preset upper base, the automobile wire harness to be cut can be placed through its inner side. Under the pressure of the finger, the reserved cutting components distributed in a staggered manner at its inner end can be used to cut the wire harness. With the cooperation of the auxiliary guiding structure, there is no need to perform cumbersome manual operations to cooperate with the mechanical structure for positioning work during the cutting process, and the automatic two-way clamping work can be carried out stably and quickly. Thus, while the device is simple, compact and convenient to operate, its cutting accuracy and stability are ensured; Furthermore, as the outer end of the preset upper base moves downward, it will contact and press the built-in support liquid sac, and thus supply work is carried out to the inside of the external support liquid sac through the supply pipe under pressure. The external support liquid sac expands to push the abutting and docking member. Since the abutting and docking member and the movable traction member are integrally connected, the movable traction member moves downward synchronously with the downward movement of the abutting and docking member, and drives the reserved steel wire rope to move downward and deform along the inner side of the preset lower base through the movable traction member, thereby performing adaptive locking treatment on the contacting wire harness. Through firm linear positioning, the situation of loosening is avoided, and adaptive locking treatment is carried out while cutting, enabling the user to accurately perform the cutting work and improving the practicability of the device; Furthermore, an auxiliary limiting structure is provided to perform lateral positioning treatment on the contacting wire harness. During the process that the abutting and docking member moves downward along the inner side of the preset lower base under force, it will press on the contacting "L"-shaped movable positioning member through the outer inclined surface-like structure, so that the lower end of the movable positioning member is synchronously pressed, and the second return spring forms a lateral sliding structure along the inner side of the horizontal guiding groove, and then cooperates with the oppositely arranged movable positioning members to stably synchronously position the lower end of the contacting wire harness, and cooperate with the reserved steel wire rope for linear positioning to perform multi-directional locking treatment on the contacting wire harness, ensuring its subsequent cutting stability.
