Description

Technical Field

[0001] The utility model relates to the field of wire harness crimping, in particular to a wire harness crimping preprocessing device. Background Art

[0002] In contemporary automobile production, electronic control systems are closely related to wiring harnesses. The second production factor of wiring harnesses is crimping. The quality of the wire harnesses after crimping is directly related to the experience of using the car. In order to improve the service life and performance of the wire harnesses, the wire harnesses are usually deoxidized.

[0003] The existing wire harness deoxidation treatment is to immerse the wire harness after opening into an acetic acid solution, so that the acetic acid removes the oxide on the surface of the metal wire to achieve the purpose of deoxidation treatment. However, since the wire harness needs to be handheld by the staff and immersed in the acetic acid solution, it consumes manpower and the staff may accidentally touch the acetic acid solution and burn the skin.

[0004] Therefore, a wire harness crimping pretreatment device has been developed that can automatically press the wire harness into an acetic acid solution for treatment, saving manpower and preventing workers from accidentally touching the acetic acid solution and burning their skin. Utility Model Content

[0005] In order to overcome the shortcomings of the existing wire harness deoxidation treatment, which requires workers to hold the wire harness and immerse it in an acetic acid solution, which is labor-intensive and may cause the workers to accidentally touch the acetic solution and burn their skin, the utility model provides a wire harness crimping pretreatment device that can automatically press the wire harness into the acetic solution for treatment, saving manpower and preventing workers from accidentally touching the acetic solution and burning their skin.

[0006] The technical scheme of the utility model is: a wire harness crimping pretreatment device, comprising a bracket, a pickling box, a drainage pipe and a pressing mechanism, the bracket is provided with two left and right brackets, the pickling box is connected between the upper sides of the brackets, the drainage pipe is connected to the left side of the lower part of the pickling box, and the pickling box is provided with a pressing mechanism capable of pressing the wire harness into an acetic acid solution.

[0007] In one of the embodiments, a reinforcement sheet is provided on the bracket.

[0008] In one of the embodiments, a control valve is provided on the liquid discharge pipe.

[0009] In one embodiment, the pressing mechanism includes a fixed frame, a cylinder, a pressing frame, a roller, a placement plate, a rotating plate and a torsion spring. A fixed frame is connected between the front and rear sides of the upper part of the pickling box, a cylinder is connected to the middle of the fixed frame, a pressing frame is connected to the telescopic end of the cylinder, the lower part of the pressing frame is rotatably connected to the roller, a placement plate is connected to the upper right side of the pickling box, a rotating plate is rotatably connected to the left side of the placement plate, and torsion springs are connected between the front and rear sides of the rotating plate and the placement plate.

[0010] In one embodiment, the roller is a concave wheel structure.

[0011] In one of the embodiments, a stabilizing mechanism is also included, which includes a sliding plate, a stabilizing pressure block and a linear spring. The sliding plate is slidably connected to the press-in frame, a stabilizing pressure block is connected to the right side of the sliding plate, and a linear spring is connected between the sliding plate and the press-in frame.

[0012] The beneficial effects are: 1. The utility model starts the cylinder on the fixed frame to push the pressing frame downward, so that the roller moves downward and the extrusion rotating plate rotates 90 degrees counterclockwise, and the torsion spring is deformed, so that the wire harness is immersed in the acetic acid solution, thereby achieving the effect of automatically pressing the wire harness into the acetic acid solution for treatment, saving manpower and avoiding workers from accidentally touching the acetic acid solution and burning their skin.

[0013] 2.

DETAILED DESCRIPTION

[0019] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0020] A wire harness crimping preprocessing device, such as Figure 1 and Figure 2As shown, it includes a bracket 1, a pickling box 2, a drain pipe 3 and a pressing mechanism 4. There are two brackets 1 on the left and right. The bracket 1 is provided with a reinforcement sheet to enhance stability. The pickling box 2 is connected between the upper sides of the brackets 1. The drain pipe 3 is connected to the lower left side of the pickling box 2. A control valve is provided on the drain pipe 3 to control the opening and closing. The pickling box 2 is provided with a pressing mechanism 4.

[0021] like Figure 1 and Figure 3 As shown, the pressing mechanism 4 includes a fixed frame 41, a cylinder 42, a pressing frame 43, a roller 44, a placement plate 45, a rotating plate 46 and a torsion spring 47. The fixed frame 41 is connected between the front and rear sides of the upper part of the pickling box 2, the cylinder 42 is connected to the middle of the fixed frame 41, the pressing frame 43 is connected to the telescopic end of the cylinder 42, the lower part of the pressing frame 43 is rotatably connected to the roller 44, the roller 44 is a concave wheel structure, which is convenient for pressing the wire harness, the placement plate 45 is connected to the upper right side of the pickling box 2, the placement plate 45 is rotatably connected to the rotating plate 46 on the left side, and the rotating plate 46 is connected to the placement plate 45 on both the front and rear sides with a torsion spring 47.

[0022] When using the utility model, first close the drain pipe 3, pour the acetic acid solution into the pickling box 2, and then immerse the wire harness after the wire is opened in the acetic acid solution, so that the acetic acid removes the oxides on the surface of the metal wire. When the acetic acid solution needs to be replaced, the drain pipe 3 can be opened to discharge the acetic acid solution from the pickling box 2. When the wire harness is immersed in the acetic solution, the wire harness can be placed on the placement plate 45 and the rotating plate 46, and then the cylinder 42 on the fixed frame 41 is started to push the pressing frame 43 to move downward, so that the roller 44 moves downward to squeeze the rotating plate 46 to rotate counterclockwise 90 degrees, and the torsion spring 47 is deformed, so that the wire harness is immersed in the acetic acid solution. When the wire harness is processed, the roller 44 is separated from the rotating plate 46, and restored by the torsion spring 47, driving the rotating plate 46 to reset, thereby playing the role of automatically pressing the wire harness into the acetic solution for processing, saving manpower and avoiding the staff from accidentally touching the acetic solution and burning the skin.

[0023] like Figure 1 and Figure 4 As shown, it also includes a stabilizing mechanism 5, which includes a sliding plate 51, a stabilizing pressure block 52 and a linear spring 53. The sliding plate 51 is slidably connected to the press-in frame 43, the stabilizing pressure block 52 is connected to the right side of the sliding plate 51, and a linear spring 53 is connected between the sliding plate 51 and the press-in frame 43.

[0024] By using the stabilizing mechanism 5 of the device, the stability of the wire harness when pressed into the acetic acid solution can be maintained. When the pressing frame 43 moves downward, the sliding plate 51 is driven to move downward, so that the stabilizing pressure block 52 contacts the wire harness on the placement plate 45. When the roller 44 squeezes the rotating plate 46 to rotate, the sliding plate 51 moves upward on the pressing frame 43. The action of the spring makes the stabilizing pressure block 52 always contact the placement plate 45, thereby pressing the wire harness tightly on the placement plate 45 to prevent the wire harness from moving.

[0025] The above description is only an example of the implementation of the present invention and is not intended to limit the present invention. Any equivalent replacement made within the principle of the present invention shall be included in the protection scope of the present invention. The contents not elaborated in the present invention belong to the existing technology known to the technicians in this professional field.
