Description

Technical Field

[0001] This utility model relates to the field of wire harness assembly technology, and in particular to a multi-station rotary wire harness pre-assembly and positioning device. Background Technology

[0002] A wire harness is the main network component in a circuit. It connects various electrical components in the circuit to achieve a closed circuit. Wire harnesses are usually made by crimping copper contact terminals (i.e., connectors) with wires and cables, and then molding an insulator or an external metal shell to bundle the wire harness into a component that connects the circuit. During the production of wire harnesses, both ends of the wire harness need to be crimped into the terminals, and the tightness of the crimping determines the production quality of the wire harness.

[0003] In existing wire harness production, pre-assembly is typically performed. This involves threading silicone tubes through both ends of the wire harness before crimping terminals. The silicone tubes prevent water ingress and protect the wire harness at the metal hole edge of the terminal after crimping. However, since both ends of the wire harness require pre-assembly with silicone sleeves, and the wire harness is unloaded and fed from a winding reel, the existing process requires operators to first thread the cut ends of the wire harness through the silicone tubes before crimping. This slows down the process of threading the wire harness through the silicone tubes, affecting the overall efficiency of wire harness production. Therefore, this application proposes a multi-station rotary wire harness pre-assembly and positioning device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a multi-station rotary wire harness pre-assembly and positioning device.

[0005] The purpose of this utility model is achieved through the following technical solution: a multi-station rotary wire harness pre-assembly and positioning device, including a base, a lower ring frame that rotates by a motor is installed above the base, an upper ring frame that can reciprocate up and down is installed directly above the lower ring frame, and multiple circumferential array fixing frames are installed on the inner sides of the lower ring frame and the upper ring frame. Each of the multiple fixing frames has a reciprocating gripper installed inside, which corresponds one-to-one and is divided into multiple groups.

[0006] Optionally, the bottom surface of the base is equipped with a plurality of uniformly arranged support legs.

[0007] Optionally, an upper assembly plate is installed below the lower ring frame. The bottom surface of the upper assembly plate is provided with an annular groove, and the top surface of the base is provided with multiple ball grooves. Rolling balls are rotatably installed inside the multiple ball grooves and roll along the annular grooves.

[0008] Optionally, a lower assembly plate is installed in the middle of both the lower ring frame and the upper ring frame. The two lower assembly plates are respectively connected to multiple fixed frames, and a first telescopic cylinder is installed between the two lower assembly plates.

[0009] Optionally, each of the plurality of fixing frames is equipped with a second telescopic cylinder, and each of the output ends of the plurality of second telescopic cylinders is equipped with a mounting plate, and the plurality of grippers are respectively mounted on the outside of the mounting plate.

[0010] This utility model has the following advantages: This multi-station rotary wire harness pre-assembly and positioning equipment uses a base as its main body. A lower ring frame is rotatably mounted on top of the base, and an upper ring frame that can reciprocate up and down is mounted above the lower ring frame. The two have the same structure. Multiple circumferentially arrayed fixing frames are installed inside the lower and upper ring frames. Each fixing frame has reciprocating grippers installed inside. In use, the upper and lower grippers in the same group hold the wire harness. By moving the upper ring frame up and down, the wire harness can be straightened or positioned. This facilitates the simultaneous processing of multiple wire harnesses in the next step and is suitable for wire harnesses of various specifications.

[0011] Multiple rolling balls are rotatably mounted on the top surface of the base, and an annular groove is opened on the bottom surface of the lower ring frame. The multiple rolling balls roll along the annular groove, which can reduce the friction between the two parts and play a certain role in limiting movement. Attached Figure Description

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0015] like Figures 1 to 5 As shown, the multi-station rotary wire harness pre-assembly and positioning equipment includes a base 1. A lower ring frame 2, which is driven to rotate by a motor 7, is installed above the base 1. An upper ring frame 3, which can move up and down, is installed directly above the lower ring frame 2. Multiple circular array fixing frames 12 are installed on the inner sides of both the lower ring frame 2 and the upper ring frame 3. The interior of each fixing frame 12 is equipped with a reciprocating gripper 6, which corresponds one-to-one and is divided into multiple groups.

[0016] As an optional technical solution of this utility model, the bottom surface of the base 1 is equipped with a plurality of uniformly arrayed support legs 10, which makes it easy to place the entire device stably.

[0017] As an optional technical solution of this utility model, an upper assembly plate 13 is installed below the lower ring frame 2. The bottom surface of the upper assembly plate 13 is provided with an annular groove 15, and the top surface of the base 1 is provided with multiple ball grooves 11. Rolling balls 8 are rotatably installed inside the multiple ball grooves 11, and they all roll along the annular grooves 15. This reduces the friction between the ring frame and the base 1 and can limit the rotation of the ring frame.

[0018] As an optional technical solution of this utility model, a lower assembly plate 14 is installed in the middle of both the lower ring frame 2 and the upper ring frame 3. The two lower assembly plates 14 are connected to multiple fixed frames 9 respectively. A first telescopic cylinder 9 is installed between the two lower assembly plates 14, which facilitates the installation of the first telescopic cylinder 9 and enables the upper ring frame 3 to move up and down.

[0019] As an optional technical solution of this utility model, a second telescopic cylinder 4 is installed inside the multiple fixing frames 9, and an mounting plate 5 is installed at the output end of the multiple second telescopic cylinders 4. Multiple grippers 6 are respectively installed on the outside of the mounting plate 5, so that the grippers 6 can be moved to adjust the position of the clamped wire harness.

[0020] In summary, the features, assembly method, usage process, and functions of each component in this utility model are as follows: The base 1 serves as the main body of the device. A lower ring frame 2 is rotatably mounted above the base 1, and an upper ring frame 3, capable of reciprocating up and down, is mounted above the lower ring frame 2. Both have the same structure. Multiple circumferentially arrayed fixing frames 12 are installed inside the lower ring frame 2 and the upper ring frame 3. Each fixing frame 12 contains reciprocating grippers 6. During use, the grippers 6 in the same upper and lower group clamp the wire harness. The up and down movement of the upper ring frame 3 allows for straightening or positioning of the wire harness, facilitating simultaneous tooling of multiple wire harnesses and applicability to various specifications of wire harnesses. Multiple rolling balls 8 are rotatably mounted on the top surface of the base 1. An annular groove 15 is formed on the bottom surface of the lower ring frame 2, and the multiple rolling balls 8 roll along the annular groove 15, reducing friction between the two components and providing a certain degree of limiting.
