Technical Field

[0001] The utility model relates to a pressing mechanism, in particular to a pressing mechanism with adjustable wire harness width. Background Art

[0002] Automotive electronics has always played an important role in automotive manufacturing. With the development of the automotive industry, the requirements for automotive electronics are becoming increasingly strict. To ensure that each functional component of automotive electronics realizes its function, an automotive wire harness is needed as a bridge to connect various electronic parts of the vehicle, and two wire harnesses need to be butted.

[0003] At present, the conventional wire harness butting method uses manual welding. Manual welding is not only inconvenient to operate, but also the welding process is prone to jitter, resulting in relative displacement of the two wire harnesses and the need for re-welding, which affects the welding quality. Therefore, it is necessary to design a wire harness welding machine that can automatically weld wire harnesses. Among them, the pressing mechanism for the lateral width of the wire harness is a relatively important mechanism. However, the current width pressing mechanisms are either complex in structure or single in structure, and cannot effectively adjust the width of the wire harness, resulting in poor adaptability and inability to meet the development needs of enterprises.

Specific embodiments

[0030] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0031] The present utility model provides a pressing mechanism with adjustable wire harness width to solve the problems in the prior art that when manual welding is used for wire harness welding, the width of the welded wire harness cannot be adjusted, the welding efficiency is low, and it does not meet the requirements of batch processing by enterprises.

[0032] For the convenience of understanding, the specific process in the embodiments of the present application will be described below. Please refer to Figures 1 to 4 A pressing mechanism with adjustable wire harness width in the embodiments of the present application includes a placing plate 1, a left wire pressing mechanism 2, a right wire pressing mechanism 3 and an adjusting mechanism 4; the placing plate 1 is horizontally arranged in a long strip shape; the left wire pressing mechanism 2 is fixedly arranged on one side of the placing plate 1; the right wire pressing mechanism 3 is arranged on the other side of the placing plate 1 with adjustable width relative to the left wire pressing mechanism 2 through the adjusting mechanism 4. The adjusting mechanism 4 includes a base 40, and a through sliding groove 400 is opened in the base 40; the transverse moving block 41 is slidably arranged in the sliding groove 400, and an inclined slot 410 is opened on the upper surface of the transverse moving block 41, and the inclination direction of the inclined slot 410 is towards the side close to the left wire pressing mechanism 2; the sliding column 42 is slidably arranged in the inclined slot 410; the reference block 43 is arranged above the base 40, and the right wire pressing mechanism 3 is horizontally slidably arranged above the reference block 43; both ends of the connecting rod assembly 44 are respectively connected with the sliding column 42 and the right wire pressing mechanism 3.

[0033] The pressing mechanism with adjustable harness width of the present utility model. When the transverse block 41 slides to drive the sliding column 42 to move transversely in the inclined groove 410, the sliding column 42 drives the right wire pressing mechanism 3 to slide on the opposite side of the left wire pressing mechanism 2 through the connecting rod assembly 44.

[0034] Furthermore, in this embodiment, the transverse block 41 is driven by a driving cylinder 44 to move transversely in the sliding groove 400, and the sliding column 42 is vertically slidably arranged in the inclined groove 410. When the driving cylinder 44 drives the transverse block 41 to move forward, the sliding column 42 correspondingly moves obliquely in the inclined groove 410, and its movement trajectory is a transverse approaching movement relative to the left wire pressing mechanism 2, thereby converting the linear movement of the sliding column 42 into a transverse movement.

[0035] Specifically, based on Figure 2 and Figure 4 , in this embodiment, the connecting rod assembly 44 includes a sliding seat 440, a connecting rod 441, a connecting shaft 442 and a middle rotating shaft 443; the sliding seat 440 is installed above the base 40 and is connected to the sliding column 42. In this way, when the sliding column 42 slides in the inclined groove 410 and moves transversely, the sliding seat 440 synchronously follows the sliding column 42 to move transversely.

[0036] One end of the connecting rod 441 is rotatably arranged on the connecting shaft 442, the connecting shaft 442 is transversely installed inside the sliding seat 440, and the other end passes through the sliding seat 440 and the reference block 43 and is connected to the right wire pressing mechanism 3; the middle rotating shaft 443 is installed at the middle part of the connecting rod 441, and both ends of the middle rotating shaft 443 are exactly transversely arranged at both ends of the reference block 43.

[0037] When the sliding seat 440 and the sliding column 42 move transversely in a follow-up manner, the connecting rod 441 is synchronously driven to rotate around the middle rotating shaft 443. Specifically, when the sliding seat 440 moves forward, the connecting rod 441 at this time deflects to the left around the middle rotating shaft 443, thereby driving the right wire pressing mechanism 3 connected to the connecting rod 441 to slide to the left in the reference block 43. The right wire pressing mechanism 3 and the left wire pressing mechanism 2 cooperate with each other to transversely press the harness located on the placement plate 1, which is convenient and labor-saving to operate, and is mechanically driven, and the operation stability is reliable.

[0038] Further, if there is no limit on the sliding position of the transverse movement block 41 within the sliding groove 400, the transverse movement block 41 may disengage from the base 40 during transverse movement. Therefore, a limiting mechanism 9 is provided to limit the forward movement position of the transverse movement block 41. The limiting mechanism 9 includes a connecting rod 93 perpendicularly connected to the transverse movement block 41; the connecting rod 93 extends downward after passing through the base 40 to the front end of a blocking block 92; and the blocking block 92 is arranged on a screw rod 91; the screw rod 91 drives the blocking block 92 to move horizontally at the front end of the connecting rod 93 via a limiting motor 90.

[0039] During operation, the limiting motor 90 starts to work. The limiting motor 90 drives the blocking block 92 to move to a set position in front of the connecting rod 93 through the screw rod 91. When the transverse movement block 41 is driven by a driving cylinder 44 to move forward horizontally, at this time, the connecting rod 93 moves synchronously with the transverse movement block 41. When the connecting rod 93 moves to the set position, the blocking block 92 blocks the connecting rod 93 from continuing to move forward, thereby limiting the forward movement position of the transverse movement block 41, preventing the transverse movement block 41 from directly sliding out of the base 40, and ensuring the reliability and stability during operation.

[0040] Further, the opposite sides of the left wire pressing block and the right wire pressing block on the opposite sides of the left wire pressing mechanism 2 and the right wire pressing mechanism 3 are both serrated, so that the pressing of the wire harness is more firm and no sliding will occur.

[0041] Based on Figures 1 to 4 , the specific usage process is described as follows.

[0042] Manually place the wire harness on the placement plate 1 and make the wire harness located between the left wire pressing mechanism 2 and the left wire pressing mechanism 3.

[0043] At this time, start the driving cylinder 44. The driving cylinder 44 drives the transverse movement block 41 to slide within the sliding groove 400 of the base 40. During the sliding, it synchronously drives the sliding column 42 to move horizontally relative to the left wire pressing mechanism 2. The sliding seat 440 follows the sliding column 42. After the sliding seat 440 slides horizontally, it drives the connecting rod 441 to tilt towards the left wire pressing mechanism 2, thereby causing the right wire pressing mechanism 3 to slide horizontally to the right within the reference block 43. The right wire pressing mechanism 3 and the left wire pressing mechanism 2 approach each other, thereby clamping the wire harness.

[0044] For the wire harness width-adjustable pressing mechanism of the present utility model, the driving cylinder drives the sliding column to slide within the inclined groove, and the sliding column drives the right wire pressing mechanism to slide relatively within the reference block through the connecting rod, so that the width between the right wire pressing mechanism and the left wire pressing mechanism is adjustable to adapt to wire harnesses of different widths to be welded. The operation is convenient and simple, the operation is stable and reliable, and it meets the requirements of batch production and processing.

[0045] As described above, the above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
