Description

Technical Field

[0001] The utility model relates to the technical field of automobile wiring harness assembly, in particular to an expander for automobile wiring harness rubber parts. Background Art

[0002] In order to achieve the insulation and shielding effect of the wire harness or to protect the wire harness, a wire harness hose will be sheathed on the outside of the wire harness. In addition to the wire harness hose, the outside of the automobile air-conditioning wire harness will also be sheathed with rubber parts to make the connection between the wire harness and the automobile frame simpler and faster, and the fixation more convenient and firm. At present, in the process of automobile wire harness assembly, an expander is required to expand the rubber parts.

[0003] The existing expander only has the functions of expansion and closing. When expanding, the rubber part of the wire harness is stretched open by the expansion claws, and the wire harness is assembled inside the rubber ring. Then, when the expansion claws are closed, the wire harness and the rubber ring are assembled. At this time, the inner wall of the rubber ring fits tightly with the outer wall of the expansion claws. The employee needs to use the strength of both arms to keep the rubber part open and take it off forcefully, otherwise the wire harness will be clamped in the clamping mechanism of the expander. When the quality of the rubber part is poor, there is also a phenomenon of breaking open and popping out. If it bounces onto the operator's body, it will cause varying degrees of injury.

[0017] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0018] Example 1

[0019] An expansion machine for automotive wiring harness rubber parts, such as Figure 1 to Figure 2 As shown, it includes an operating platform 1, an operating button 9 is provided on the front side of the operating platform 1, an expansion seat 2 is provided on one side of the upper surface of the operating platform 1, and a power-assisting mechanism for removing the rubber member is slidably provided on the other side, and an expansion claw 3 is provided on the expansion seat 2;

[0020] The power-assisting mechanism includes a mounting frame 8 slidably arranged on the operating platform 1. Specifically, tracks 6 are respectively arranged on the front and rear sides of the upper surface of the operating platform 1. Slide grooves 12 corresponding to the tracks 6 are respectively provided on the bottom sides of the mounting frame 8. The mounting frame 8 is slidably clamped on the tracks 6 through the slide grooves 12. A plurality of fixing plates 7 are arranged at one end of the mounting frame 8 close to the expansion seat 2. A limit baffle 4 is respectively arranged on each fixing plate 7. An oblong hole 13 is provided on the limit baffle 4. The limit baffle 4 is fixed to the fixing plate 7 by bolts arranged in the oblong hole 13. The oblong hole 13 can be used to adjust the position of the limit baffle 4 so that it can better cooperate with the rubber part in limiting position and expand its general range. A power-assisting cylinder 5 is arranged on the rear side of the mounting frame 8. An air inlet pipe and an air outlet pipe are connected to the power-assisting cylinder 5. The telescopic end of the power-assisting cylinder 5 is connected to one side of the expansion seat 2. After the rubber piece is sleeved on the expansion claw 3, the limit baffle 4 is located on the right side of the rubber piece. The limit baffle 4 can limit and block the assembled wiring harness rubber piece, and then remove it from the expansion claw 3 under the action of the booster cylinder 5, which can reduce the labor intensity of the employees;

[0021] In order to further improve the safety of the rubber member during expansion, a transparent protective cover 11 is hinged on the rear side of the operating platform 1 to prevent the rubber member from being broken and ejected during expansion. A handle 10 is provided on the transparent protective cover 11 to facilitate opening or closing the protective cover 11.

[0022] The working method of the utility model is as follows: when in use, the staff puts the rubber piece on the expansion claw 3, the limit baffle 4 limits and blocks the expansion claw 3, and then the expansion claw 3 is moved to open the rubber piece, the wire harness is passed into the rubber ring, and then the transparent protective cover 11 is opened. When the expansion claw 4 is closed, the rubber ring and the wire harness are assembled, and the power-assisting cylinder 5 is started at the same time, the entire mounting frame 8 moves to the left, and the staff holds the wire harness in their hands, so that the limit baffle 4 drives the blocked rubber ring to move horizontally to the left, and then the rubber ring is removed from the expansion claw 4. In this process, the rhythm of the power-assisting cylinder 5 and the expansion claw 4 when closed is consistent.

[0023] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
