Description

Technical Field

[0001] This utility model belongs to the field of pin crimping technology, and particularly relates to an axial positioner for crimping insertion pins. Background Technology

[0002] Wires in aircraft are crucial carriers for signal and energy transmission, and given their wide application, their manufacturing methods are receiving increasing attention. Especially in wire crimping, the quality of the crimp directly affects the performance of the finished product after the electrical connector is mated with it. When crimping pins with crimping pliers, an axial positioner ensures the accuracy of the crimp mark for each pin crimp.

[0003] Patent CN221407931U discloses an axial locator for crimping pins. In its structure, the locator body is cylindrical with a pin mounting hole at its central axis. A locator flange is fixedly mounted on one end face of the locator body, and a pin mounting boss is fixedly mounted on the end face of the locator flange. Both the pin mounting boss and the locator flange have through holes coaxial with the pin mounting hole, used to insert the pin entirely into the pin mounting hole of the pin mounting boss, the locator flange, and the locator body. A positioning recess is provided on one side of the outer edge of the locator flange for positioning with a locator alignment pin on the crimping pliers. The technical solution provided by this utility model solves the problem that when crimping pins with crimping pliers, the operator needs to manually determine the crimping position, which makes it difficult to ensure the quality of the crimping and reduces overall work efficiency.

[0004] In existing technologies, a pin mounting boss can be used to position the pin for crimping by means of the pin's outer platform. However, the following problems still exist in overall use: First, the hole diameter of existing axial positioners is usually fixed. When crimping pins of different sizes, the axial positioner needs to be replaced, resulting in low crimping efficiency. Second, when positioning the pin, the existing pin is positioned by means of an external boss. However, pins come in various styles, and existing devices are not convenient for fixing and adjusting the crimping length, resulting in poor adaptability and extreme inconvenience in use. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this utility model provides an axial positioner for crimping pins. By setting a directional plate that can be tensioned, it solves the problem of frequent replacement of the axial positioner when crimping pins of different sizes, thus improving work efficiency. By setting a limit rod and a knob structure, it solves the problem that the existing device is not convenient for fixing and adjusting the crimping length, thereby improving ease of use and work efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an axial positioner for crimping insertion pins, comprising a connecting ring, an outer shell on the outer surface of the connecting ring, two drive rings rotatably disposed inside the outer shell, the two drive rings being symmetrically disposed inside the outer shell, a plurality of tensionable guide plates slidably disposed between the two drive rings, a positioning block for positioning the pin slidably disposed between the plurality of guide plates, and a knob rotatably disposed at one end of the outer shell, the knob being drively connected to the positioning block.

[0007] Preferably, one end of each of the two drive rings is provided with a damping shaft, one end of the damping shaft is fixedly connected to the outer surface of the connecting ring, and one end of the damping shaft is fixedly connected to the inner wall of the housing.

[0008] Preferably, the outer surfaces of both drive rings are provided with a plurality of drive grooves along the circumferential direction, and a plurality of slide rods are slidably arranged inside the plurality of drive grooves. One end of each of the plurality of slide rods is provided with a movable plate. The plurality of movable plates are fixedly connected to the directional plate. Fixing blocks are provided on the outer surfaces of the plurality of movable plates and the outer surfaces of the drive rings. The plurality of fixing blocks are slidably connected to the movable plates.

[0009] Preferably, the plurality of drive grooves are generally arc-shaped, and one end of the plurality of drive grooves is inclined toward the center of the drive ring.

[0010] Preferably, each of the multiple orientation plates has a positioning groove on its outer surface, and each of the multiple positioning grooves has a limiting rod slidably disposed inside it. One end of each of the multiple limiting rods is fixedly connected to the outer surface of the positioning block.

[0011] Preferably, one end of the knob is provided with a threaded rod, which is threadedly connected to the positioning block.

[0012] Preferably, a fixing groove is provided on the inner wall of the directional plate, and an elastic element is provided inside the fixing groove, with one end of the elastic element extending outward from the inside of the fixing groove.

[0013] Preferably, one end of the elastic element is provided with a deformation adaptation groove, and the protruding end of the elastic element is provided with a groove.

[0014] Preferably, the outer surface of the housing is provided with two sliding grooves, and an adjusting rod is slidably disposed inside the two sliding grooves. The two ends of the adjusting rod are respectively fixedly connected to two drive rings.

[0015] Preferably, one side of one of the grooves is provided with a scale on the outer surface of the housing.

[0016] In summary, compared with existing technologies, the beneficial effects of this solution are as follows:

[0017] (1) By setting up multiple directional plates, movable plates and adjusting rods, this utility model can adjust the distance between each directional plate by rotating the adjusting rod, so that the directional plate adapts to the diameter of the pin, thereby achieving the effect of adjusting the internal diameter of the axial positioner and improving the adaptability of the device;

[0018] (2) By setting a limiting rod, a positioning block, a positioning groove, and a knob, the positioning block can slide inside the shell. The position of the sliding positioning block limits the length of the pin entering the shell, thereby controlling the pressing position of the pin. This device can easily adjust the pressing position of the pin, improve the working efficiency during use, and by setting an elastic element and a groove, the pin is fixed by the elastic potential energy of the elastic element when it enters the shell, preventing the pin from shaking during pressing, thereby improving the pressing quality of the pin.

Detailed Implementation

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] refer to Figure 1 and Figure 2The device includes a connecting ring 10, which is circular in shape. Multiple fixing bolts 11 are provided on the outer surface of the connecting ring 10. The connecting ring 10 is fixedly mounted on the outside of a crimping pliers using the fixing bolts 11. The crimping pliers are a type of pliers specifically designed for crimping operations. By applying strong pressure, they permanently, firmly, and reliably connect metal terminals (connectors) to the conductors of wires or cables. The outer surface of the connecting ring 10 is provided with a housing 12, which is cylindrical in shape. Two damping shafts 27 are provided inside the housing 12. One end of one damping shaft 27 is fixedly connected to the outer surface of the connecting ring 10, and the other end is fixedly connected to the inner wall of the housing 12. The damping shafts 27 are existing technology and can form a self-locking mechanism through their own resistance, thereby preventing the connection parts from rotating arbitrarily and improving the overall stability of the device.

[0027] Further reference Figure 2 , Figure 3 and Figure 4 Two drive rings 17 are rotatably arranged between two damping shafts 27. Multiple drive grooves 18 are provided on the outer surface of each drive ring 17 along the circumferential direction. The multiple drive grooves 18 are generally arc-shaped, with one end inclined towards the center of the drive ring 17. Multiple sliding rods 19 are slidably arranged inside each drive groove 18. A movable plate 20 is provided at one end of each sliding rod 19, and a directional plate 21 is provided at one end of each movable plate 20. The directional plates 21 are generally arc-shaped and can form a circle when they are close together. Fixing blocks 22 are provided on the outer surface of each movable plate 20 and on the outer surface of the drive ring 17. The fixing blocks 22 are slidably connected to the movable plates 20, and both fixing blocks 22 are fixedly connected to the inner wall of the outer shell 12. By setting the fixing blocks 22, the sliding direction of the movable plates 20 can be restricted, allowing the movable plates 20 to slide only in a centripetal direction. By rotating the two drive rings 17... 7. This causes the two drive rings 17 to drive the multiple drive grooves 18 on the outer surface to rotate. After rotation, the multiple drive grooves 18 drive the internal slide rods 19 to move through the inner wall of the drive grooves 18. This causes the slide rods 19 to move along the inner wall of the drive grooves 18. Because the drive grooves 18 are rotating, and the movable plate 20 at one end of the slide rod 19 is restricted by the fixed block 22, the slide rod 19 slides centripetally through the fixed block 22, thereby driving the movable plate 20 at one end to slide centripetally. The multiple movable plates 20 drive the multiple directional plates 21 at one end to move in a tensioned manner towards the center, thereby adjusting the diameter of the inner shell 12. This allows the pins entering the inner shell 12 to move against the inner wall of the directional plates 21, thereby axially positioning the pins. By adjusting the diameter of the inner shell 12, pins of different diameters can be axially positioned, thereby improving the adaptability of the device.

[0028] Further reference Figure 1 , Figure 2 and Figure 3 The outer surface of the outer casing 12 is provided with two sliding grooves 14. An adjusting rod 15 is slidably arranged inside the two sliding grooves 14. The two ends of the adjusting rod 15 are fixedly connected to two drive rings 17 respectively. By setting the adjusting rod 15, the two drive rings 17 can be rotated at the same time, thereby providing a power source for the drive rings 17. A scale 13 is set on one side of the outer surface of the outer casing 12. The angle of rotation of the drive ring 17 can be determined by setting the scale 13. Since the rotation of the drive ring 17 can drive the directional plate 21 to move, the position of multiple directional plates 21 inside the outer casing 12 can be determined by the angle of the drive ring 17, so as to adjust the distance between the directional plates 21.

[0029] Further reference Figure 2 , Figure 3 and Figure 4 The outer surface of multiple directional plates 21 is provided with positioning grooves 23, and the interior of multiple positioning grooves 23 is provided with limiting rods 24. One end of multiple limiting rods 24 is provided with a positioning block 25 that can position the pin. The interior of the positioning block 25 is provided with a threaded rod 26, and one end of the threaded rod 26 is provided with a knob 16 outside the outer shell 12.

[0030] Further reference Figure 2 , Figure 3 and Figure 5 The inner wall of the directional plate 21 is provided with a fixing groove 28, and an elastic element 29 is provided inside the fixing groove 28. The elastic element 29 is made of rubber. One end of the elastic element 29 extends outward from the inside of the fixing groove 28 to abut against the pin entering the inside of the outer shell 12. When the pin enters the inside of the outer shell 12, it will squeeze the protruding end of the elastic element 29, causing the elastic element 29 to deform. One end of the elastic element 29 is provided with a deformation adaptation groove 31. By providing a deformation adaptation groove 31, the elastic element 29 can retract into one end of the deformation adaptation groove 31 when it deforms, thereby providing elasticity. The component 29 provides a space for movement. When squeezed, the adapting groove 31 deforms, allowing the pin on one side to enter the interior of the outer shell 12. At the same time, the deformed adapting groove 31 recovers due to elastic potential energy and pushes the elastic component 29 to reset, so that the protruding end of the elastic component 29 abuts against the outer surface of the pin. The pin is fixed by the friction of the surface of the elastic component 29. The protruding end of the elastic component 29 is provided with a groove 30. By providing the groove 30, the protruding end of the elastic component 29 can be provided with deformation space when squeezed, preventing the protruding end of the elastic component 29 from being squeezed and damaged by the groove opening of the fixing groove 28.
