Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness production technology, specifically to a hole-expanding device for automotive wiring harness production. Background Technology

[0002] Existing enlarging devices for automotive wiring harness production typically enlarge the holes in rubber waterproof rings using a pair of enlarging plates. These plates move relative to each other via an electrically operated telescopic rod. In practice, the rubber waterproof ring is placed on the plates, and the telescopic rod is manually retracted to enlarge the hole in the ring. The rod is then stopped extending. After inserting the wiring harness into the ring, the rod is extended again to close the plates, facilitating the removal of the ring and wiring harness. This process requires constant manual adjustment of the electric telescopic rod, which is cumbersome and reduces the device's enlarging efficiency.

[0003] Utility model CN222301263U discloses a hole-expanding device for automotive wiring harness production, comprising a base plate, a frame vertically mounted on the upper part of the base plate, a through-groove on the right end of the frame, a movable plate slidably connected within the groove, a U-shaped clamp plate in contact with the movable plate mounted on the upper right side of the groove, and arc-shaped plates with opposing arc grooves mounted on the upper right sides of the frame and the movable plate, respectively. A lifting assembly connected to the movable plate is mounted at the rear end of the frame, and an adjusting assembly is mounted at the lower end of the frame. The advantages of this utility model are: through the cooperation of the lifting assembly, motor, half-gear, gear, and movable plate, a pair of arc-shaped plates move up and down relative to each other and cyclically open and close, thereby facilitating hole expansion of rubber waterproof rings and insertion of automotive wiring harnesses, and making it easy to remove both together without the need for continuous manual control of the telescopic rod, thus improving the hole-expanding efficiency of the device.

[0004] However, the above-mentioned existing technology still has shortcomings in use: after the rubber waterproof ring and wire harness are tied together, they are still in close contact with a pair of arc plates, which makes it inconvenient to separate the rubber waterproof ring and the arc plates.

[0005] Therefore, this utility model provides a hole-expanding device for automotive wiring harness production. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a hole-expanding device for automotive wiring harness production, thereby solving the problems mentioned in the background art. This utility model has the function of assisting in the feeding of rubber waterproof rings, making it easier to separate the wiring harness and rubber waterproof rings from the device after they are joined, eliminating the need for manual operation and saving more effort.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a hole-expanding device for automotive wiring harness production, comprising a base, an annular positioning disk above the base, at least three rotating shafts distributed around the center on the annular positioning disk, one end of each rotating shaft being connected to an eccentric shaft via a connecting plate, a control assembly for controlling all rotating shafts to rotate synchronously in the same direction on one side of the annular positioning disk, and a material feeding auxiliary mechanism on the annular positioning disk.

[0008] Furthermore, the control assembly includes a turntable and a transmission gear. The transmission gear is fixedly sleeved on the other end of the rotating shaft, and the turntable is rotatably connected to the rear plate surface of the annular positioning plate and meshes with the transmission gear.

[0009] Furthermore, the control assembly includes a control motor and a drive gear. The control motor is fixedly mounted on one side of the annular positioning disk, and its output shaft is fixedly connected to the drive gear that meshes with the turntable.

[0010] Furthermore, a side plate is fixedly connected to the outer peripheral wall of the annular positioning disk, the control motor is fixedly mounted on one side of the side plate, and the driving gear is a bevel gear structure.

[0011] Furthermore, the feeding auxiliary mechanism includes a push plate and a connecting ring. The push plate is sleeved on the eccentric shaft and the two slide in a circumferential manner. One end of the push plate is fixedly connected to a guide shaft that is sleeved inside the rotating shaft and is slidably arranged. The connecting ring is located on the back of the annular positioning disk and one side of it is rotatably connected to one end of the guide shaft.

[0012] Furthermore, the material feeding auxiliary mechanism also includes an electric telescopic rod, which is fixedly mounted on the outer periphery of the annular positioning plate and its output shaft is fixedly connected to one side of the connecting ring.

[0013] Furthermore, the number of the electric telescopic rods is two, and they are symmetrically distributed relative to the annular positioning disc.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, at least three eccentric shafts for hole enlargement are provided, and a feeding auxiliary mechanism is provided on the annular positioning plate. The feeding auxiliary mechanism is provided with a push plate and a connecting ring. Each eccentric shaft is fitted with a push plate. When the rubber waterproof ring and the wire harness are connected, the push plate can push the rubber waterproof ring on the eccentric shaft away when the connecting ring is pushed. This arrangement has the advantages of making feeding easier and more convenient after hole enlargement and connection.

[0016] 2. In this utility model, at least three rotating shafts are arranged around the annular positioning plate. The rotating shafts are connected by a connecting plate and an eccentric shaft. The eccentric shaft and the rotating shaft connected to it are eccentrically distributed. By rotating all the rotating shafts synchronously in the same direction, the holes of the rubber waterproof ring can be uniformly enlarged as a whole, which makes it easier for the wire harness to pass through. The high red setting has the advantage of making wire harness docking more convenient. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1 to 3This utility model provides a technical solution: a hole-expanding device for automotive wiring harness production, including a base 1, an annular positioning disk 2 above the base 1, and at least three rotating shafts 3 arranged around the center on the annular positioning disk 2. In this embodiment, the number of rotating shafts 3 is three. The surface of the annular positioning disk 2 has circumferentially evenly distributed positioning holes that are rotatably connected to the rotating shafts 3. The axis of the rotating shaft 3 is parallel to the axis of the annular positioning disk 2. One end of the rotating shaft 3 is connected to an eccentric shaft 4 through a connecting plate 7. The axis of the eccentric shaft 4 is parallel to the axis of the rotating shaft 3. When the rotating shaft 3 rotates, the eccentric shaft 4 and the annular positioning disk 2 are connected to each other. The distance between the positioning discs 2 will vary. During use, ensure that the three eccentric shafts 4 are evenly distributed circumferentially relative to the axis of the annular positioning disc 2. When the distance between the eccentric shafts 4 and the annular positioning disc 2 is at its minimum, the rubber waterproof ring can be placed on the outside of the three eccentric shafts 4. Then, control the three rotating shafts 3 to rotate synchronously in the same direction. At this time, the three eccentric shafts 4 will evenly expand the rubber waterproof ring. Then, insert the wire harness into the evenly expanded rubber waterproof ring. When the rotating shafts 3 continue to rotate or rotate in the opposite direction, the inner hole of the rubber waterproof ring will be reduced. Then, when the rubber waterproof ring and the wire harness are removed together, the rubber waterproof ring is placed on the outside of the wire harness.

[0023] Furthermore, a control assembly 5 is provided on one side of the annular positioning disk 2 to control all rotating shafts 3 to rotate synchronously in the same direction.

[0024] Specifically, the control assembly 5 includes a turntable 51 and a transmission gear 53. The transmission gear 53 is fixedly sleeved on the other end of the rotating shaft 3. The turntable 51 is rotatably connected to the rear plate surface of the annular positioning disk 2 and meshes with the transmission gear 53. In specific implementation, a support ring can be welded to the rear plate surface of the annular positioning disk 2. A mating sleeve that is rotatably connected to the support ring is welded to one side of the turntable 51. An internal gear ring that meshes with the transmission gear 53 is fixedly sleeved on the inner peripheral wall of the turntable 51. Thus, when the control turntable 51 rotates, it can simultaneously drive the three rotating shafts 3 to rotate.

[0025] Furthermore, the control assembly 5 includes a control motor 52 and a drive gear 54. The control motor 52 is fixedly mounted on one side of the annular positioning disk 2, and its output shaft is fixedly connected to the drive gear 54 that meshes with the turntable 51. In a specific implementation, it is preferred that a side plate 21 is fixedly connected to the outer peripheral wall of the annular positioning disk 2, the control motor 52 is fixedly mounted on one side of the side plate 21, and the drive gear 54 is a bevel gear structure. A bevel gear ring that meshes with the drive gear 54 is fixedly connected to one side of the turntable 51. This drive arrangement can reduce the structure on the front and rear sides of the annular positioning disk 2 and avoid interference with the insertion operation of the wiring harness.

[0026] In addition, the annular positioning plate 2 is also equipped with a feeding auxiliary mechanism 6. The function of the feeding auxiliary mechanism 6 is to push the rubber waterproof ring in the expanded hole tension state away from the eccentric shaft 4, so that manual feeding is not required, making it more convenient to feed the rubber waterproof ring and wire harness after they are connected.

[0027] Specifically, the feeding auxiliary mechanism 6 includes a push plate 61 and a connecting ring 62. The push plate 61 is sleeved on the eccentric shaft 4 and the two slide in a circumferential manner. Specifically, a connecting hole that slides in a eccentric shaft 4 can be opened at one end of the push plate 61. When the push plate 61 slides, it can push the rubber waterproof ring on the eccentric shaft 4. One end of the push plate 61 is fixedly connected to a guide shaft 611 that is sleeved in the rotating shaft 3 and is slidably arranged. The rotating shaft 3 is a sleeve structure. The guide shaft 611 and the rotating shaft 3 slide in a slidable manner. The connecting ring 62 is located on the back of the annular positioning disk 2 and one side of it is rotatably connected to one end of the guide shaft 61. Thus, by pushing the connecting ring 62, the overall back-and-forth movement of all the push plates 61 can be controlled.

[0028] Furthermore, the unloading auxiliary mechanism 6 also includes an electric telescopic rod 63. The electric telescopic rod 63 is fixedly mounted on the outer periphery of the annular positioning disk 2, and its output shaft is fixedly connected to one side of the connecting ring 62. The electric telescopic rod 63 provides driving force to the movement of the connecting ring 62, and this arrangement eliminates the need for manual force application. In a specific implementation, it is preferable that there are two electric telescopic rods 63, which are symmetrically distributed relative to the annular positioning disk 2. This arrangement makes the movement of the connecting ring 62 smoother.

[0029] In use, a control box is installed on the base 1. The control box is electrically connected to the control motor 52 and the electric telescopic rod 63. The control box has a built-in controller, which sets the timing and sequence of the actions of the control motor 52 and the electric telescopic rod 63. An operation panel is set on the outside of the control box, and the operator controls the hole enlarging operation through the operation panel.

[0030] Working principle: In operation, first, control the eccentric shaft 4 to be in the position closest to the axis of the annular positioning disk 2. Then, manually pull the rubber waterproof ring onto the outside of the three eccentric shafts 4. Then, control the turntable 51 to rotate, and the rubber waterproof ring is stretched into a triangular hole. Then, insert the wire harness into this triangular hole. Then, control the turntable 51 to continue rotating, and the rubber waterproof ring shrinks. Then, control the electric telescopic rod 63 to move, and the connecting ring 62 moves and pushes the push plate 61 on the three eccentric shafts 4 to move synchronously and push the rubber waterproof ring away. At this time, the wire harness and the rubber waterproof ring attached to it can be easily removed as a whole.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
