Description

Technical Field

[0001] The utility model relates to the technical field of automotive wire harnesses, and specifically relates to a special wrapping machine for wire harnesses with terminals. Background Art

[0002] Wire harnesses are widely used in current industrial production. A wire harness is a wiring component that connects various electrical devices in a circuit and consists of an insulating sheath, wiring terminals, wires, etc. A wire harness refers to a component formed by pressing a contact terminal made of copper material onto a wire and cable, and then plastically pressing an insulator or adding a metal shell outside, etc., and bundling the wire harness to form a component for connecting the circuit. A winding wrapping machine is required for bundling the wire harness.

[0003] There is a prior art wire harness terminal parallel winding wrapping machine with a publication number of CN213705885U, which includes a support frame. The support frame includes a limit plate, a threaded sleeve, and an installation ring. The support frame is integrally welded by a vertical support frame and two ground contact mounting plates symmetrically welded at the bottom. A vertical support plate is welded in the middle section of the top crossbeam of the vertical support frame. A toothed disc is rotatably inserted in the middle section of this vertical support plate, and an installation ring is welded and fixed at the top of the vertical support plate. In the utility model, the bolt can apply a pressing braking force to the winding disc through the arc-shaped brake pad at its tail end, so that the winding disc tightens the wrapping tape on it and winds it around the wire harness, increasing the winding tightening force of the wire harness and preventing the wrapping tape from loosening.

[0004] The above prior art solution has the following defects: The winding disc vertically surrounds the wire harness. When winding and wrapping the wire harness, the winding tape on the winding disc is vertically wound. During the movement of the wire harness, the winding tape is driven to fold at a small angle, resulting in creases. There are gaps and holes in the winding of the winding tape at the crease, greatly reducing the sealing effect of the winding tape wrapping, and the quality is effectively improved. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a special wrapping machine for wire harnesses with terminals.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] It includes a base. On the top wall of the base, a pair of supporting legs are fixedly arranged. On the top wall of the supporting legs, a mounting plate is supported. The mounting plate is penetrated with a wire harness through groove. A wire harness plate is slidably arranged in the wire harness through groove. At both ends in the length direction of the wire harness plate, wire harness clamping devices are fixedly arranged. On the outer wall of the mounting plate, a connecting plate parallel to the wire harness plate extends. The connecting plates are arranged in pairs and parallel to each other up and down. At the end of the connecting plate, a winding plate is rotatably connected. On the side of the winding plate away from the connecting plate, a covering plate is rotatably connected. On the outer wall of the winding plate, a first motor for driving the covering plate to rotate is fixedly installed. On the outer wall of the covering plate, a winding disc with a winding tape is fixedly installed. In the center of the winding plate and the covering plate which are in a disc shape, an activity groove for wrapping the wire harness through groove is opened. The wire harness plate is provided with a sliding device. On the side of the winding plate away from the covering plate, a tensioning device for controlling the rotation angle of the winding plate is fixedly installed.

[0008] By adopting the above technical solution, the wire harness clamping device on the wire harness plate can effectively clamp the wire harness. Combined with the sliding device, during the process of the winding tape winding the wire harness, the wire harness can be automatically moved to achieve the effect of full-section wrapping. The tensioning device combined with the rotatably connected winding plate can adjust the angle between the winding disc and the wire harness by controlling the tensioning length. During the winding process, the winding tape can wind the wire harness obliquely to avoid generating creases that cause gap holes in the winding and affect the winding sealing effect, thereby improving the winding quality.

[0009] Furthermore, the tensioning device includes tensioning ropes fixedly connected to the winding disc. The tensioning ropes are arranged in pairs horizontally. On the outer wall of the mounting plate, a pair of buckles for cooperating with the tensioning ropes are fixedly arranged. The tensioning ropes are respectively buckled to the buckles.

[0010] By adopting the above technical solution, when it is necessary to adjust the angle of the winding disc, untie the two tensioning ropes, rotate the winding disc and then tighten the two tensioning ropes simultaneously to maintain the adjusted angle of the winding disc, and then buckle the tensioning ropes to the corresponding buckles, the winding disc can be fixed at the specified angle. The included angle between the winding disc and the wire harness can be adjusted according to actual needs to ensure that the winding tape can closely fit the surface of the wire harness during winding to avoid generating crease gaps, and it has good adjustability.

[0011] Further, the wire harness clamping device is fixedly arranged on the upper plate of the top wall of the wire harness board. The upper plates are arranged in pairs at both ends of the wire harness board. On one side of the upper plate near the wire harness through groove at one end, a first connecting column extends. At the end of the first connecting column, a first wire twisting disc is fixedly connected. On one side of the upper plate near the wire harness through groove at the other end, a second connecting column extends. At the end of the second connecting column, a second wire twisting disc is rotatably connected. The first wire twisting disc and the second wire twisting disc are in a disc shape, and a number of wire harness engaging grooves are equidistantly arranged at the edge. The second wire twisting disc is provided with a pin hole penetrating through it. The upper plate is provided with a pin inserted into the pin hole. An elastic binding ring is fitted on the outer edges of the first wire twisting disc and the second wire twisting disc.

[0012] By adopting the above technical solution, during use, both ends of a single wire harness are respectively fixed in the wire harness engaging grooves on the first wire twisting disc and the second wire twisting disc, and then the elastic binding ring is put on to fix the whole wire harness. Then, the second wire twisting disc is rotated to twist and tighten the whole wire harness. After reaching the specified number of turns, the pin is inserted to fix the second wire twisting disc. At this time, the wire harness can be successfully tightened and fixed, facilitating the subsequent winding process to proceed smoothly.

[0013] Further, the sliding device includes a pair of lower plates fixedly arranged at both ends in the length direction of the bottom wall of the wire harness board. A threaded rod is fixedly arranged between the lower plates. The mounting plate is snap-fitted and rotatably provided with a rotating cylinder threadedly engaged with the threaded rod. A rotating ring penetrating into the outer wall of the mounting plate is arranged around the outer edge of the rotating cylinder. A second motor for driving the rotating ring to rotate is fixedly installed on the outer wall of the mounting plate.

[0014] By adopting the above technical solution, the first motor and the second motor can be connected to the control system or controlled at a specified rotational speed. When the second motor rotates, it drives the rotating cylinder inside the mounting plate to rotate. Since the rotating cylinder is threadedly connected to the threaded rod, the threaded rod is driven to move along the length direction, achieving the effect of driving the wire harness board to slide.

[0015] In summary, the beneficial technical effects of the present utility model are as follows:

[0016] 1. By adopting the tensioning rope, buckle ring and the winding plate with a rotating connection, the angle between the winding disc and the wire harness can be adjusted, avoiding the generation of creases that may cause gap holes in the winding and affecting the winding sealing effect, and improving the winding quality.

[0017] 2. By adopting the first wire twisting disc, the second wire twisting disc and the elastic binding ring, the wire harness can be tightened and fixed, facilitating the subsequent winding process to proceed smoothly.

[0018] 3. By adopting the threaded rod, the rotating cylinder and the second motor, the threaded rod is driven to move along the length direction, achieving the effect of driving the wire harness board to slide. Description of the Drawings
