Description

Technical Field

[0001] The utility model relates to the technical field of wire harness manufacturing, in particular to an auxiliary fixture for terminal installation. Background Technique

[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 is composed of an insulating sheath, a wiring terminal, a wire, 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 connecting the circuit.

[0003] Contact terminals made of copper material are arranged in sequence along the length direction of the connecting belt. When installing the terminals, first place the wire harness and the terminals in coincidence, and then use a hydraulic device to strip the terminals from the connecting belt and simultaneously press-fit them with the wire harness, so that the terminals are tightly fastened on the wire harness. When the placement position of the wire harness is not in place, the part where the terminals fasten the wire harness is small, and the connection tightness is greatly reduced. In severe cases, the two may even be stripped and disconnected, and the installation quality needs to be further improved. Content of the Utility Model

[0004] The purpose of the utility model is to provide an auxiliary fixture for terminal installation.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] It includes a substrate. A plurality of wire grooves are opened on the top wall of the substrate. A limiting plate for truncating one end of the wire groove is fixedly arranged on one side of the substrate. A terminal groove perpendicular to the wire groove is opened on the top wall of the substrate. The terminal groove is arranged in contact with the side wall of the limiting plate. A terminal connecting belt is slidably arranged in the terminal groove. A plurality of metal terminals are arranged along the length direction of the terminal connecting belt. A driving device is arranged in a matching manner with the terminal connecting belt. An installation plate is fixedly installed on the top wall of the limiting plate. The outer edge of the installation plate extends out of the limiting plate and is arranged above the terminal groove. A hydraulic device for aligning the metal terminals is installed on the installation plate. A roller rack is fixedly installed on the side wall of the substrate parallel to the wire groove. A first motor is fixedly installed on the outer wall of the roller rack. An alignment roller is fixedly sleeved on the rotating shaft of the first motor. The rim of the alignment roller is spaced and aligned with the wire groove.

[0007] By adopting the above technical solution, when in use, the wire harness is placed in the wire groove, the first motor is started to drive the alignment roller to rotate, the alignment roller contacts the outer edge of the wire harness, and the rotation of the alignment roller pushes the wire harness to move towards the terminal groove until the wire harness abuts against the limit plate. At this time, the wire harness reaches the designated position. Due to the limiting effect of the limit plate, the alignment roller slips on the surface of the wire harness. At this time, the first motor is turned off, and the hydraulic device is started to press-fit the metal terminal onto the wire harness to complete the installation operation. The alignment roller combined with the limit plate can effectively transport the wire harness and align the end of the wire harness at the same time. The size of the part where the metal terminal clamps the wire harness is appropriate, ensuring that the metal terminal is firmly installed and not easily detached, facilitating the subsequent welding process. The setting of several wire grooves facilitates the batch processing of a large number of wire harnesses and improves the installation efficiency of metal terminals.

[0008] Further, a sub-bracket is hingedly installed on the roller frame. The sub-bracket is arranged parallel to the upper wall of the base. A second motor is fixedly installed on the outer wall of the end of the sub-bracket. The rotating shaft of the second motor is arranged parallel to the rotating shaft of the first motor. A sub-roller is fixedly arranged on the rotating shaft of the second motor. The rim of the sub-roller is spaced and aligned with the wire groove. The first motor and the second motor are externally connected to a power supply.

[0009] By adopting the above technical solution, the second motor combined with the sub-roller forms a second contact point with the wire harness, and at the same time, the force application points are distributed at both ends of the length direction of the wire groove, exerting force on the head and tail of the wire harness at two points to avoid bending and twisting of the wire harness during the movement process, improving the alignment effect and ensuring the installation quality.

[0010] Further, the roller frame is hingedly arranged on the outer wall of the substrate. An arc-shaped plate extending along the hinged rotation route is arranged at the bottom wall of the roller frame. A positioning block cooperating with the arc-shaped plate is fixedly arranged on the outer wall of the substrate. A sliding groove for the arc-shaped plate to slide is opened on the positioning block. A positioning column is threadedly connected to the top wall of the positioning block. The positioning column penetrates into the sliding groove and abuts against the arc-shaped plate. A rotating handle is fixedly arranged at the end of the positioning column.

[0011] By adopting the above technical solution, when the rotating handle is loosened, the arc-shaped plate slides freely along the sliding groove, facilitating the adjustment of the installation height of the alignment roller. When the wire harness is thicker, the installation height is increased; when the wire harness is too thin, the installation height is decreased. After the height adjustment is completed, the rotating handle is tightened again to lock the position of the roller frame and the alignment roller, which has a good adjustment effect.

[0012] Further, the hydraulic device includes a hydraulic telescopic rod fixedly arranged through the mounting plate. A pressing plate for aligning the metal terminal is fixedly arranged at the end of the hydraulic telescopic rod. A pressing groove is opened on the surface of the pressing plate close to the metal terminal. The hydraulic telescopic rod is externally connected to a hydraulic system.

[0013] By adopting the above technical solution, when pressing the metal terminal, the pressing groove wraps and fixes the metal terminal, and the pressing plate drives the metal terminal to be peeled off and tighten the wire harness under the drive of the hydraulic telescopic rod, which has a good positioning and pressing effect.

[0014] Further, the auxiliary brackets are arranged in pairs, a gripping handle is connected to the top wall of the auxiliary brackets, and a first control button electrically connecting the first motor and the second motor and a second control button electrically connecting the hydraulic system are fixedly installed on the outer wall of the gripping handle.

[0015] By adopting the above technical solution, the setting of the gripping handle facilitates the operator to pull and adjust the roller frame and align the heights of the alignment roller and the auxiliary roller. The settings of the first control button and the second control button facilitate the operator to select and control the operation of the first motor, the second motor and the hydraulic device according to the actual working conditions. When in use, first feed the wire harness into the wire groove, press the first control button to align the wire harness, then press the second control button to control the hydraulic system to start pressing the metal terminal, and finally press the first control button to reverse the alignment roller and the auxiliary roller to withdraw the wire harness, completing a cycle of installation.

[0016] In summary, the beneficial technical effects of the present utility model are as follows:

[0017] 1. The limit plate, the first motor and the alignment roller are adopted, so that while effectively transporting the wire harness, the end of the wire harness can be aligned, and the size of the part where the metal terminal tightens the wire harness is appropriate, ensuring the effect of firmly installing the metal terminal;

[0018] 2. The second motor and the auxiliary roller are adopted, so that double-point head and tail force are generated on the wire harness to avoid bending and twisting during the movement of the wire harness, improving the alignment effect and ensuring the installation quality;

[0019] 3. The arc-shaped plate, the positioning block, the positioning column and the rotating handle are adopted, so that the heights of the alignment roller and the auxiliary roller can be adjusted adaptively according to the thickness of the wire harness to achieve the best fit for installation.
