Technical Field

[0001] The utility model relates to the technical field of automobile wire harness crimping, in particular to a wire feeding device for an automobile wire harness crimping machine. Background Art

[0002] The crimping machine is a necessary tool for crimping wires. The wires are fed into the crimping machine through the wire-laying equipment to complete the reliable connection between the wires and terminals or other connectors.

[0003] At present, when a wire harness is crimped by a crimping machine, an operator usually pushes the wires manually, and during the pushing process, the wires are guided by a wire-releasing device to prevent the wires from bending. However, the existing device requires manual pushing of the wires during the crimping process, which is more troublesome to operate.

[0004] Therefore, in order to solve the above problems, a wire feeding device for an automotive wire harness crimping machine which can automatically convey wires and is convenient to operate has been developed. Utility Model Content

DETAILED DESCRIPTION

[0018] The present invention is further described below in conjunction with specific embodiments. It should also be noted that, unless otherwise clearly specified and limited, terms such as: setting, installing, connecting, and connecting should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] A wire feeding device for an automobile wire harness crimping machine, such as Figure 1-Figure 3 As shown, it includes a mounting frame 1, a rotating wheel 2, a lifting frame 3, an adjusting rod 4, a guide frame 5 and a conveying mechanism 6. The mounting frame 1 is rotatably connected to three rotating wheels 2, the upper part of the mounting frame 1 is slidably connected to the lifting frame 3, and the lifting frame 3 is also rotatably connected to three rotating wheels 2. The front part of the mounting frame 1 is rotatably connected to the adjusting rod 4, the lifting frame 3 is threadedly connected to the adjusting rod 4, the left and right sides of the mounting frame 1 are connected to the guide frames 5, and the mounting frame 1 is provided with a conveying mechanism 6.

[0020] like Figure 1 , Figure 2 and Figure 4 As shown, the conveying mechanism 6 includes a fixed frame 61, a motor 62, a gear set 63, a connecting shaft 64, a telescopic component 65, a transmission member 66, a first belt 67 and a second belt 68. The front right side of the mounting frame 1 is connected to the fixed frame 61, and the motor 62 is connected to the fixed frame 61. The output shaft of the motor 62 is connected to the rightmost rotating wheel 2 on the mounting frame 1. The right front part of the mounting frame 1 is rotatably connected to the connecting shaft 64, and the gear set 63 is connected between the connecting shaft 64 and the output shaft of the motor 62. The first belt 67 is wound between the connecting shaft 64 and the rightmost rotating wheel 2 on the lifting frame 3, the second belt 68 is wound between the rotating wheels 2 on the lifting frame 3, and the second belt 68 is also wound between the rotating wheels 2 on the mounting frame 1.
