Description

Technical Field

[0001] This utility model relates to the technical field of wire end processing equipment, and more specifically, it relates to a wire harness terminal crimping machine. Background Technology

[0002] A wire harness terminal crimping machine, also known as a terminal crimping machine, is a type of wire end processing equipment developed for common terminals both domestically and internationally. Its function is to crimp the terminal onto the wire end, so that the wires can be connected without welding. When disassembling the wire, simply pull out the terminal.

[0003] Chinese Patent No. CN104577628B discloses a terminal crimping machine for wires, including a workbench and an outer support housing, with a terminal placement rack connected to the side of the support housing; it also includes a cutting module for crimping terminals, a drive device for driving the cutting module, and a conveying mechanism for conveying terminal strips.

[0004] In existing technologies, terminal crimping machines similar to those described above typically use a conveying mechanism to transport terminal strips so that the terminals can remain in the cutting module. Then, a worker places the tooling end of the wire into the terminal slot, and finally, a drive device drives the cutting module to crimp the terminal onto the tooling end of the wire. However, the wire needs to be manually held and aligned with the cutting module to place it into the tooling position of the cutting module to complete the wire positioning. The existing wires are relatively thin, and it is easy for the wire to be misplaced due to the worker's poor eyesight or shaking. Utility Model Content

[0005] To address the existing technical problems, the purpose of this utility model is to provide a wire harness terminal crimping machine, which has the advantage of being able to position the tooling end of the wire.

[0006] To achieve the above objectives, this utility model provides the following technical solution: including a workbench, a support housing, a terminal placement rack, a cutting module, a driving device, and a conveying mechanism, and also including...

[0007] A guide block is horizontally set on the worktable, and the upper side of the guide block is provided with a guide groove that communicates with the groove of the cutting module.

[0008] A cylinder, the cylinder body of which is mounted on the worktable, the cylinder is located at the end of the guide block away from the cutting module, the piston rod of which extends into the upper part of the guide groove, and a pusher block that is slidably connected to the guide groove is provided on the piston rod of the cylinder.

[0009] A vacuum pumping assembly includes a pump, a pumping pipe connected to the pump, an airflow channel disposed within a guide block and connected to the pumping pipe, and multiple vacuum holes disposed within the guide block and connected at both ends to a guide groove and an airflow channel, respectively.

[0010] By adopting the above technical solution, when it is necessary to place the wire, simply place the wire in the guide block, ensuring that the tooling end of the wire is positioned on the guide groove near the die-cutting assembly. During operation, the piston rod of the control cylinder extends to its full stroke, thereby controlling the pusher block to push the tooling end of the wire into the cutting module. While the cylinder is working, the vacuum pump is simultaneously controlled to evacuate air from the airflow channel and vacuum holes, ensuring that each vacuum hole is under negative pressure. At this time, the wire can be adsorbed in the guide groove, preventing it from sliding out an extra distance due to inertia when the piston rod of the cylinder stops moving. Through the above steps, the positioning of the wire tooling can be easily completed, effectively overcoming problems such as inaccurate positioning caused by hand tremors or blurred vision, and ensuring the processing quality of the wire terminals.

[0011] The present invention is further configured such that: the guide block includes a support block whose upper surface is horizontally arranged with the groove of the cutting module, and two adjusting blocks that are respectively slidably connected to both sides of the support block; the guide groove is formed by the two adjusting blocks and the support block; and the upper end of the vacuum hole is connected to the support block.

[0012] By adopting the above technical solution, and through the sliding connection between the adjusting block and the support block, the width of the guide groove can be adjusted according to the diameter of the wire, effectively improving the range of applications.

[0013] The present invention is further configured such that: each of the two adjusting blocks is provided with multiple adjusting grooves arranged along the length direction of the adjusting block, and the length direction of each adjusting groove is perpendicular to the length direction of the adjusting block; both sides of the support block are provided with multiple bolts arranged along the length direction of the support block and passing through each adjusting groove; each bolt is threaded with a nut.

[0014] By adopting the above technical solution, the adjustment block can be clamped and fixed on the support block by the cooperation between the bolt and nut that passes through the adjustment groove, so that the adjustment groove is not easy to move or misalign due to collision after being positioned.

[0015] The present invention is further configured such that: each of the two adjusting blocks has a beveled surface on one side facing each other to form a guide channel in the shape of a trumpet.

[0016] By adopting the above technical solution, the funnel-shaped guide channel makes it easier for workers to place the wire between the two adjustment blocks.

[0017] The present invention is further configured such that the junction of the inner wall of each vacuum hole and the upper surface of the support block is rounded.

[0018] By adopting the above technical solution, the wire will rub against the connection between the vacuum hole and the support block when it slides in the guide groove. Rounding the corners at the junction of the inner wall of the vacuum hole and the upper surface of the support block can prevent the wire from being scratched by the vacuum hole when it moves.

[0019] The present invention is further configured such that: a screw rod arranged parallel to the cylinder is rotatably connected to the worktable; a bushing threadedly connected to the screw rod is provided on the cylinder body of the cylinder; and the cylinder body of the cylinder is snap-fitted and slidably connected to the worktable.

[0020] By adopting the above technical solution, through the cooperation between the screw and the bushing and the snap-fit ​​sliding relationship between the cylinder and the worktable, the working position of the cylinder along the length of the guide groove can be adjusted when the screw rotates, so that the cylinder can perform pushing work according to wires of different lengths, effectively improving the scope of application.

[0021] The present invention is further configured such that a rotating handle is provided at the end of the screw away from the guide block.

[0022] By adopting the above technical solution, the screw can be easily rotated by the operator by turning the handle.

[0023] The present invention is further configured such that: a sliding groove is provided on the workbench along the length direction of the cylinder and the cross-section is in the shape of a "T"; multiple sliding blocks with the cross-section in the shape of a "T" are provided on the cylinder body; and each sliding block is engaged with the sliding groove.

[0024] By adopting the above technical solution, the T-shaped guide block and the guide groove are engaged and cooperated, which not only restricts the horizontal displacement of the guide block relative to the guide groove, but also restricts the vertical displacement of the guide block relative to the guide groove, so that the sliding of the first outer support block and the second outer support block on the guide sleeve is more stable.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] (1) The tooling part of the wire can be automatically pushed into the groove of the cutting module through the cooperation between the guide block, cylinder and vacuum pumping assembly, without the need for manual positioning, thus reducing the workload of the workers;

[0027] (2) The adjustable working position adjustment block and the cylinder can be adjusted for wires of different diameters and lengths, and have a wide range of applications. Attached Figure Description
