Description

Technical Field

[0001] This utility model belongs to the field of positioning pin technology, and more specifically, it relates to adjustable KCF positioning pins. Background Technology

[0002] In the automotive manufacturing industry, KCF locating pins are used for positioning bolts and nuts during welding, ensuring electrical safety and positioning accuracy. They possess excellent insulation, wear resistance, high-temperature resistance, oxidation resistance, and toughness. They come in two types: round head and pointed head. Round heads are mostly used for manual placement, while pointed heads offer better stability when used with feeders. An existing KCF locating pin for processing automotive parts, with publication number CN208322821U, uses a modular approach, combining locating pins of different diameters based on locating holes of varying diameters. This method is cumbersome, and the large number of models makes it difficult to quickly locate the correct pin. Therefore, an adjustable KCF locating pin is proposed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an adjustable KCF positioning pin. When the inner support plate moves inward, the KCF positioning pin is used in positioning holes with smaller diameters; when the inner support plate moves outward, the KCF positioning pin is used in positioning holes with larger diameters. This solves the problem mentioned in the background technology that, by combining positioning pins of different diameters according to positioning holes of different diameters, the operation is cumbersome and there are too many models, making it difficult to quickly find the positioning pin.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an adjustable KCF positioning pin, comprising a positioning pin body, with multiple mounting grooves on the outer side of the positioning pin body, inner support plates slidably connected to the inner sides of the multiple mounting grooves, inclined surfaces on opposite sides of the multiple inner support plates, two movable grooves on opposite sides of the multiple inner support plates, fitting grooves on the top surfaces of the two movable grooves, a rotating groove inside the positioning pin body, a sleeve rotatably connected inside the rotating groove, two turntables fixed to the outer side of the sleeve, planar threads on the top surfaces of the two turntables, slidably connected to the inner side of the fitting grooves on the outer side of the planar threads, and a groove on the top surface of the positioning pin body, with an external hexagonal nut on the inner side of the groove.

[0005] As a preferred technical solution of this utility model, a mounting base is provided below the positioning pin body, and a connecting stud is fixed on the bottom surface of the mounting base.

[0006] As a preferred embodiment of this utility model, the top surface of the mounting base is provided with multiple connecting grooves, and a connecting rod is slidably connected to the inner side of the connecting groove. The upper end of the connecting rod is fixedly connected to the bottom surface of the positioning pin body.

[0007] As a preferred embodiment of this utility model, a sleeve rod is rotatably connected to the inner side of the sleeve, the upper end of the sleeve rod is provided with an internal hexagonal groove, and the lower end of the sleeve rod is connected to the internal thread of the mounting base.

[0008] As a preferred embodiment of this utility model, the plurality of mounting slots are arranged in a cross shape.

[0009] As a preferred embodiment of this utility model, the interior of the rotating groove is connected to the interior of multiple mounting grooves.

[0010] As a preferred technical solution of this utility model, the inner side of the external hexagonal nut is fixedly connected to the upper outer side of the sleeve.

[0011] This utility model provides an adjustable KCF positioning pin, which has the following beneficial effects:

[0012] The adjustable KCF locating pin allows it to be used in smaller diameter locating holes when the inner support plate moves inward, and in larger diameter locating holes when the inner support plate moves outward. This solves the problem of cumbersome operation and difficulty in quickly finding the right locating pin when combining different diameter locating pins for different diameter locating holes using a modular method.

[0013] 2. The adjustable KCF locating pin engages with the internal hexagonal groove on the sleeve rod via an internal hexagonal wrench, thereby driving the sleeve rod to rotate. The lower end of the sleeve rod is connected to the internal thread of the mounting base, thereby driving the mounting base to move along the connecting rod, thus adjusting the distance between the mounting base and the locating pin body, and improving the applicability.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: an adjustable KCF positioning pin, including a positioning pin body 1, a plurality of mounting grooves 2 on the outer side of the positioning pin body 1, an inner support plate 4 slidably connected to the inner side of each of the plurality of mounting grooves 2, an inclined surface 5 on the opposite side of each of the plurality of inner support plates 4, two movable grooves 6 on the opposite side of each of the plurality of inner support plates 4, a fitting groove 7 on the top surface of each of the two movable grooves 6, a rotating groove 8 inside the positioning pin body 1, a sleeve 9 rotatably connected inside the rotating groove 8, two turntables 10 fixed on the outer side of the sleeve 9, a planar thread 11 on the top surface of each of the two turntables 10, the outer side of the planar thread 11 slidably connected to the inner side of the fitting groove 7, a groove 12 on the top surface of the positioning pin body 1, and an external hexagonal nut 13 on the inner side of the groove 12;

[0023] The external wrench engages with the external hexagonal nut 13 on the sleeve 9, causing the sleeve 9 to rotate. The sleeve 9 then rotates the two turntables 10. During this process, the flat thread 11 on the turntable 10 slides into the fitting groove 7 on the inner support plate 4, thereby pushing or pulling the inner support plate 4 inward or outward along the mounting groove 2 on the locating pin body 1. When the inner support plate 4 moves inward, the KCF locating pin is used in the locating hole with a smaller diameter. When the inner support plate 4 moves outward, the KCF locating pin is used in the locating hole with a larger diameter. Through the above process, the problem of combining locating pins of different diameters according to the locating holes of different diameters in a combined manner is solved, which is cumbersome and makes it difficult to quickly find the locating pins due to the large number of models.

[0024] Furthermore, a mounting base 14 is provided below the positioning pin body 1. A connecting stud 15 is fixed on the bottom surface of the mounting base 14. Multiple connecting grooves 16 are opened on the top surface of the mounting base 14. A connecting rod 17 is slidably connected to the inner side of the connecting groove 16. The upper end of the connecting rod 17 is fixedly connected to the bottom surface of the positioning pin body 1. A sleeve rod 3 is rotatably connected to the inner side of the sleeve 9. An internal hexagonal groove 18 is opened at the upper end of the sleeve rod 3. The lower end of the sleeve rod 3 is threadedly connected to the inside of the mounting base 14. Multiple mounting grooves 2 are arranged in a cross shape. The inside of the rotating groove 8 is connected to the inside of the multiple mounting grooves 2. The inner side of the external hexagonal nut 13 is fixedly connected to the upper outer side of the sleeve 9.

[0025] The sleeve rod 3 is driven to rotate by engaging the hex wrench with the hex socket 18 on the sleeve rod 3. The lower end of the sleeve rod 3 is connected to the internal thread of the mounting base 14, thereby driving the mounting base 14 to move along the connecting rod 17, thereby adjusting the distance between the mounting base 14 and the locating pin body 1, thus improving the applicability.

[0026] The specific usage and function of this embodiment: This utility model uses an external wrench to engage with the external hexagonal nut 13 on the sleeve 9, thereby driving the sleeve 9 to rotate. The sleeve 9 drives the two turntables 10 to rotate. During this process, the planar thread 11 on the turntable 10 is slidably connected to the fitting groove 7 on the inner support plate 4, thereby pushing or pulling the inner support plate 4 to move inward or outward along the mounting groove 2 on the positioning pin body 1. When the inner support plate 4 moves inward, the KCF positioning pin is used in the positioning hole with a smaller diameter. When the inner support plate 4 moves outward, the KCF positioning pin is used in the positioning hole with a larger diameter.

[0027] The sleeve 3 is driven to rotate by engaging the hex wrench with the hex socket 18 on the sleeve 3. The lower end of the sleeve 3 is connected to the internal thread of the mounting base 14, thereby driving the mounting base 14 to move along the connecting rod 17, thereby adjusting the distance between the mounting base 14 and the locating pin body 1.
