Description

Technical Field

[0001] This utility model relates to the field of wire harness processing, specifically to a wire harness clamping device. Background Technology

[0002] When processing wire harnesses (such as conductive wires), a wire harness clamping device is often required to clamp and fix them to achieve positioning. Existing wire harness clamping devices have the following structure: two clamping components are hinged together and driven by linear actuators such as cylinders to swing, achieving opening and closing in a swinging manner, as shown in a clamp for clamping wire harnesses disclosed in CN205312212U. Using this method, the two clamping components have movement in two directions. After fully opening, the clamping components can retract to make room, without affecting the subsequent translation of the wire harness. However, for processing wire harnesses with large spans in cross-sectional area (i.e., large variations in wire diameter), the clamping process initially contacts the lower half of the wire harness, which can easily lead to significant changes in the clamping center, affecting subsequent processing. Utility Model Content

[0003] Therefore, to solve the above problems, this utility model provides a wire harness clamping device.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] A wire harness clamping device includes a fixed plate, a drive plate, and two sets of clamping assemblies. The fixed plate is provided with two guide rails, each of which includes an arc-shaped segment and a first straight segment extending towards each other from the front end of the arc-shaped segment. The two sets of clamping assemblies are arranged opposite each other and each includes a guide rod, a slider, a jaw clamp, and a drive unit. The guide rod is hinged to the fixed plate, the slider is slidably mounted on the guide rod, the jaw clamp and the drive unit are both mounted on the slider, and the drive unit also cooperates with the guide rail of the fixed plate. The drive plate is slidably mounted on the fixed plate and drives the drive units of the two sets of clamping assemblies, thereby causing the drive units of the two sets of clamping assemblies to reciprocate on the two guide rails respectively.

[0006] The driving part of the clamping assembly moves on the arc section of the guide rail, causing the clamping assembly to swing around the hinge point of the guide rod; the driving part of the clamping assembly moves on the first straight section of the guide rail, causing the slider of the clamping assembly to translate on the guide rod, thereby causing the jaws of the two sets of clamping assemblies to form a linear opening and closing action.

[0007] Furthermore, the two guide rails on the fixed plate are arranged symmetrically, and the two sets of clamping components are also arranged symmetrically.

[0008] Furthermore, the direction toward the central axis between the two guide rails is defined as inward, and the direction away from the central axis between the two guide rails is defined as outward. The arc-shaped segment of the guide rail extends inward from front to back.

[0009] Furthermore, the inner end of the guide rod facing the central axis between the two guide rails is hinged to the fixed plate.

[0010] Furthermore, the two guide rails of the fixing plate are through guide rail slots; the driving part of the clamping assembly is a driving rod, which passes through the guide rail slot.

[0011] Furthermore, the fixing plate has a limiting recess on the side away from the slider, around the guide rail slot, and a limiting ring is mounted on the drive rod, with the limiting ring abutting against the limiting recess.

[0012] Furthermore, the drive plate and the clamping assembly are respectively disposed on opposite sides of the fixed plate, and the drive rod passes through the guide rail slot and engages with the drive plate on the other side.

[0013] Furthermore, the drive plate has a drive track that cooperates with the drive unit. The drive track includes a second straight section located at the front end and an inclined section that connects to the outer end of the second straight section, extends rearward, and is inclined inward. The forward movement of the drive plate relative to the fixed plate pushes the drive unit to move within the arcuate section of the fixed plate and transition to the first straight section through the second straight section. As the drive plate continues to move forward, the inclined section drives the drive unit to translate inward along the first straight section of the fixed plate.

[0014] Furthermore, the drive track is a drive slot hole opened on the drive plate, and the drive part passes through the drive slot hole of the drive plate to achieve drive engagement.

[0015] Furthermore, it also includes a driver, which is fixed to the rear end of the fixed plate and drives the connection to the drive plate.

[0016] The technical solution provided by this utility model has the following beneficial effects:

[0017] The wire harness clamping device of this application enables the two sets of clamping components to simultaneously possess the functions of swinging clearance and translational opening and closing. Specifically, the driving part of the clamping component moves on the first straight section of the guide rail, driving the slider of the clamping component to translate on the guide rod, thereby causing the jaws of the two sets of clamping components to form a linear opening and closing action, ensuring accurate positioning of the wire harness and preventing the center position of the wire harness from shifting. At the same time, after the two sets of clamping components open a certain distance in a straight line, the driving part of the clamping component moves on the arc section of the guide rail, causing the clamping component to swing around the hinge point of the guide rod as the center, realizing swing retraction to achieve clearance. It also has the advantages of simple structure and easy implementation. Attached Figure Description

These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0028] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0029] Reference Figures 1 to 8As shown, this embodiment provides a wire harness clamping device, including a fixing plate 10, a drive plate 20, and two sets of clamping assemblies 30. The fixing plate 10 is provided with two guide rails 11. For clarity in describing this solution, as shown... Figure 3 As shown, the front and rear ends of the wire harness clamping device are defined. The direction towards the central axis I between the two guide rails 11 is defined as inward, and the direction away from the central axis I between the two guide rails 11 is defined as outward. Each guide rail 11 includes an arc-shaped segment 112 and a first straight segment 111 extending inward from the front end of the arc-shaped segment 112; that is, the first straight segment 111 connects to the front end of the arc-shaped segment 112 and extends inward in a straight line. The two opposing first straight segments 111 are parallel or on the same straight line; in this specific embodiment, the two first straight segments 111 are on the same straight line. The arc-shaped segment 112 of the guide rail 11 curves inward from front to back.

[0030] Two sets of clamping assemblies 30 are arranged opposite each other, and each includes a guide rod 31, a slider 32, a jaw clamp 34, and a drive unit 33. The guide rod 31 is hinged to the fixed plate 10. In this embodiment, both guide rods 31 are hinged to the fixed plate 10 at their inner ends facing the central axis I between the two guide rails 11. The slider 32 is slidably mounted on the guide rod 31. The jaw clamp 34 and the drive unit 33 are both mounted on the slider 32. Specifically, the jaw clamp 34 and the drive unit 33 are respectively mounted on opposite ends of the slider 32. The drive unit 33 is also fitted onto the guide rail 11 of the fixed plate 10. The drive plate 20 is slidably mounted on the fixed plate 10 and drives the drive units 33 of the two sets of clamping assemblies 30, thereby driving the drive units 33 of the two sets of clamping assemblies 30 to reciprocate on the two guide rails 11 respectively. The driving part 33 of the clamping assembly 30 moves on the arc-shaped section 112 of the guide rail 11, causing the clamping assembly 30 to swing around the hinge point of the guide rod 31. The driving part 33 of the clamping assembly 30 moves on the first straight section 111 of the guide rail 11, causing the slider 32 of the clamping assembly 30 to translate on the guide rod 31. At this time, the first straight section 111 and the guide rod 31 are parallel, thereby causing the jaws 34 of the two sets of clamping assemblies 30 to form a linear opening and closing action.

[0031] The specific operation can be broken down as follows: When performing clamping operations, the drive plate 20 slides forward relative to the fixed plate 10, simultaneously driving the drive parts 33 of the two sets of clamping components 30 to slide from back to front on the arc-shaped segments 112 of the two guide rails 11, thereby driving the clamping components 30 to swing inward around the hinge point of the guide rod 31. While the guide rod 31 is swinging, the slider 32 will slide on the guide rod 31 to adaptively adjust its position. When the drive part 33 slides to the front end of the arc-shaped segment 112, as the drive plate 20 continues to move forward, it drives the drive part 33 to translate from the outside to the inside on the first straight segment 111, thereby causing the claws 34 of the two sets of clamping components 30 to form a straight line and finally clamp the wire harness 100; ensuring that the wire harness 100 will not deviate and achieving precise positioning. When released, the drive plate 20 slides backward relative to the fixed plate 10, simultaneously driving the drive parts 33 of the two sets of clamping assemblies 30 to slide from the inside to the outside on the first straight sections 111 of the two guide rails 11. This drives the sliders 32 of the two sets of clamping assemblies 30 to move away from each other until they reach the outer end of the first straight section 111. Then, as the drive plate 20 continues to move backward, it drives the drive parts 33 to slide from front to back on the arc-shaped section 112, causing the two sets of clamping assemblies 30 to swing outward around the hinge point of the guide rod 31, thereby achieving swing retraction and making way. It also has the advantages of simple structure and easy implementation.

[0032] Furthermore, in this embodiment, the two guide rails 11 on the fixing plate 10 are arranged axially symmetrically, and the two sets of clamping components 30 are also arranged axially symmetrically; the movements are unified, which is beneficial for production and processing. Of course, in other embodiments, an axially symmetrical structure may not be used. For example, in the arc segments 112 of the two guide rails 11, one arc segment 112 can have a larger arc than the other arc segment 112, so that the clamping component 30 corresponding to the arc segment 112 with the larger arc can retract faster. One guide rail 11 can also be enlarged or reduced proportionally based on the other guide rail 11; as long as it can be ensured that a straight line is formed when clamping and that the two sets of clamping components 30 can be flipped and retracted after opening, it is acceptable.

[0033] The inner end of the guide rod 31, facing the central axis I between the two guide rails 11, is hinged to the fixed plate 10, which makes assembly simple and rotation more flexible. Of course, in other embodiments, the guide rod 31 can also be hinged at other positions (such as the middle position).

[0034] Furthermore, in this embodiment, the drive plate 20 has a drive rail 21 that cooperates with the drive part 33. The drive part 33 is driven to perform corresponding movements on the guide rail 11 through the cooperation of the drive rail 21. One preferred embodiment is that the drive rail 21 includes a second straight section 211 located at the front end and an inclined section 212 that connects to the outer end of the second straight section 211 and extends rearward and inward, resembling a "7"-shaped structure. The forward movement of the drive plate 20 relative to the fixed plate 10 pushes the drive part 33 to move within the arc-shaped section 112 of the fixed plate 10 through the second straight section 211 and transitions to the first straight section 111. As the drive plate 20 continues to move forward, the inclined section 212 drives the drive part 33 to translate inward along the first straight section 111 of the fixed plate 10. The inclined section 212 can push the drive part 33 to move laterally within the first straight section 111. Moreover, when the drive plate 20 is continuously subjected to driving force, the inclined section 212 can continuously apply a holding force to the drive part 33, making the clamping more stable. This setup results in a simple structure and is easy to implement.

[0035] The two guide rails 11 of the fixing plate 10 are through guide rail slots 1; the driving part 33 of the clamping assembly 30 is a driving rod 3, which passes through the guide rail slot 1. The driving plate 20 and the clamping assembly 30 are respectively arranged on opposite sides of the fixing plate 10. The driving rail 21 of the driving plate 20 is a driving slot 2 opened on the driving plate 20. The driving rod 3 passes through the guide rail slot 1 and fits into the driving slot 2 of the driving plate 20 on the other side. In this way, the linkage assembly of the fixing plate 10, the driving plate 20 and the clamping assembly 30 is well realized, and the driving plate 20 and the clamping assembly 30 will not interfere with each other.

[0036] Preferably, the fixing plate 10 has a limiting recess 12 recessed around the guide rail slot 1 on the side opposite to the slider 32. A limiting ring 331 is mounted on the drive rod 3, and the limiting ring 331 abuts against the limiting recess 12. This ensures stable assembly of the clamping component 30 and prevents the clamping component 30 from wobbling or shifting relative to the fixing plate 10, thus avoiding movement jamming. Simultaneously, a pulley 332 is also mounted on the drive rod 3, which engages with the guide rail slot 1 and the drive slot 2, reducing friction and making the movement smoother.

[0037] The above discloses a preferred mating structure of the fixing plate 10, the drive plate 20 and the clamping assembly 30. Of course, it is not limited to this in other embodiments. For example, the drive plate 20 and the clamping assembly 30 can also be arranged on the same side, and the drive rail 21 that cooperates with the drive part 33 can also adopt other structures such as ">".

[0038] The fixed plate 10 is provided with a slide rail 13 extending forward and backward in the middle position and slide grooves 14 on both sides. The drive plate 20 cooperates with the slide rail 13 and slide grooves 14 to achieve guided assembly.

[0039] It also includes a driver 40, which is fixed to the rear end of the fixing plate 10 and drives the drive plate 20, thereby making the wire harness clamping device a whole; specifically, the driver 40 is a device capable of linear drive, such as a cylinder, hydraulic cylinder, or electric push rod. Of course, in other embodiments, the driver 40 may also be separate from the fixing plate 10.

[0040] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
