Description

Technical Field

[0001] This utility model relates to the field of packaging, specifically to an assembly shaft and gear testing device. Background Technology

[0002] In existing gear inspection technologies, when inspecting gears with different bore diameters, it is usually necessary to machine a mandrel that fits tightly to the bore diameter of each gear. While this mandrel design can meet the inspection requirements of gear bore diameters to some extent, it has several shortcomings. First, since the bore diameter of each gear may be different, a mandrel needs to be machined individually for each gear, which not only increases production costs but also wastes inspection resources. Second, once the traditional mandrel is machined, its diameter remains fixed, making it difficult to adapt to the inspection requirements of gear bore diameters within different tolerance ranges, resulting in poor flexibility. Utility Model Content

[0003] The purpose of this invention is to provide an assembly shaft that can be adapted to gears with different bore diameters, has high stability, and extends service life.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an assembly shaft for assembling gears, the assembly shaft comprising a base having a plurality of grooves, a slider disposed within the grooves, an adjusting sleeve sleeved on the base, an elastic pressure plate disposed between the adjusting sleeve and the slider, and a locking structure for locking the adjusting sleeve onto the base, the grooves and the slider extending along the longitudinal direction of the base, the slider having an insertion section extending into the adjusting sleeve and an assembly section for assembling with the gear, a groove being formed on the insertion section, a locking groove being formed on the adjusting sleeve, the elastic pressure plate having a pressing portion located within the groove and side wings extending from both sides of the pressing portion, the pressing portion abutting the slider radially inward, the side wings being disposed within the locking groove, the base having a first section and a second section extending downward from the first section, the adjusting sleeve being mounted on the second section, the first section having a conical structure.

[0005] Furthermore, an elongated groove extending along the longitudinal direction of the substrate is formed on the substrate, and the bottom end of the bolt is located in the elongated groove.

[0006] This utility model also provides a gear inspection device, including the aforementioned assembly shaft and an inspection probe located in the assembly groove.

[0007] The beneficial effects of this utility model are as follows: The assembly shaft of this application, through the cooperative design of the slider, adjusting sleeve, elastic pressure plate, and the first section of the base in a conical structure, realizes the flexible adjustment of the diameter of the slider assembly section, thereby adapting to the testing needs of gears with different hole diameters. It eliminates the need to process mandrels separately for each gear, reducing production costs and the waste of testing resources. Furthermore, by forming a retaining groove on the adjusting sleeve and placing the side wings of the elastic pressure plate in the retaining groove, the slider is held only by the pressing part, avoiding contact between the elastic pressure plate and the base. This prevents the elastic pressure plate from rubbing against the base when the slider and adjusting sleeve move relative to the base, thus helping to extend the service life of the assembly shaft and improving the smoothness and flexibility of adjustment.

[0008] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0017] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0018] Please combine Figures 1 to 5 The assembly shaft 100 shown in a preferred embodiment of this application is used for assembling a gear 200. The assembly shaft 100 includes a base 10 having a plurality of grooves 11, a slider 20 disposed within the grooves 11, an adjusting sleeve 30 sleeved on the base 10, an elastic pressure plate 40 disposed between the adjusting sleeve 30 and the slider 20, and a locking structure for locking the adjusting sleeve 30 onto the base 10. The grooves 11 and the slider 20 extend along the longitudinal direction of the base 10, wherein the end of the groove 11 that penetrates the base 10 away from the adjusting sleeve 30. The slider 20 has an insertion section 21 extending into the adjusting sleeve 30 and an assembly section 22 for assembling with the gear 200. A groove 23 is formed on the submerged section 21, and a locking groove 31 is formed on the adjusting sleeve 30. The elastic pressure plate 40 has a pressing part 41 located in the groove 23 and side wings 42 extending from both sides of the pressing part 41. The pressing part 41 abuts against the slider 20 in the radial direction, and the side wings 42 are disposed in the locking groove 31. The base 10 has a first section 12 and a second section 13 extending downward from the first section 12. Figure 1 , Figure 3 (As shown in the direction indicated by arrow a, pointing downwards), the adjusting sleeve 30 is installed on the second section 13, and the first section 12 has a conical structure.

[0019] The assembly shaft 100, through the tapered design of the slider 20, adjusting sleeve 30, elastic pressure plate 40, and the first section 12 of the base 10, achieves flexible adjustment of the diameter of the assembly section 22 of the slider 20. This allows it to adapt to the inspection requirements of gears 200 with different bore diameters, eliminating the need to process mandrels individually for each gear 200, thus reducing production costs and the waste of inspection resources. Furthermore, by forming a retaining groove 31 on the adjusting sleeve 30, the side wing 42 of the elastic pressure plate 40 is placed within the retaining groove 31, with the slider 20 held only by the pressing part 41. This avoids contact between the elastic pressure plate 40 and the base 10, preventing the elastic pressure plate 40 from rubbing against the base 10 when the slider 20 and adjusting sleeve 30 move relative to the base 10. This helps extend the service life of the assembly shaft 100 and improves the smoothness and flexibility of adjustment.

[0020] In this embodiment, the assembly section 22 includes an upper assembly section 221 and a lower assembly section 22. In the radial direction, the thickness of the lower assembly section 22 is greater than the thickness of the upper assembly section 221, thus accommodating more gears 200 in size. To improve the compatibility between the slider 20 and the first section 12, in an alternative embodiment, the slider 20 is made of an elastic material.

[0021] To facilitate the assembly of the elastic pressure plate 40 and prevent its displacement, each elastic pressure plate 40 includes a first side wing and a second side wing, which are mirror images of each other. Specifically, the first and second side wings are formed by bending and extending from both sides of the pressing part 41. Each locking groove 31 includes a first locking groove for locking the first side wing and a second locking groove for locking the second side wing, which are also mirror images of each other. Specifically, the first and second locking grooves are slots formed by radially outward extension of the inner wall of the self-adjusting sleeve 30. The side wing 42 is held in the slot. By setting the locking groove 31 as a slot, during assembly, the side wing 42 is inserted into the slot and held directly by the slot. Thus, no additional fixing structure is required, making the overall structure simpler.

[0022] In practical use, to avoid friction between the elastic pressure plate 40 and the base 10, after the assembly shaft 100 is assembled, the elastic pressure plate 40 has a bottom end 43 close to the base 10 in the radial direction, with a gap between the bottom end 43 and the base 10. This gap prevents contact between the elastic pressure plate 40 and the base 10. To facilitate fixing the slider 20 and prevent the slider 20 from wobbling relative to the elastic pressure plate 40, in this embodiment, the cross-section of the pressing part 41 is semi-arc-shaped. Furthermore, this structure of the pressing part 41 allows for more uniform pressure on the slider 20, improving the stability and uniformity of the pressure applied, thereby enhancing the transmission efficiency of the assembly shaft 100.

[0023] A through hole 32 is formed on the side wall of the adjusting sleeve 30, and a protrusion 211 is formed in the submerged section 21 extending radially. The protrusion 211 is inserted into the through hole 32. This design not only achieves precise positioning between the adjusting sleeve 30 and the slider 20, but also enhances the stability of their connection and prevents the assembly shaft 100 from loosening during operation.

[0024] In this embodiment, the locking structure includes a threaded hole (not labeled) on the adjusting sleeve 30 and a bolt 50 inserted into the threaded hole, with the bottom end 43 of the bolt 50 abutting against the base 10. An elongated groove 14 extending along the longitudinal direction of the base 10 is formed on the base 10, and the bottom end 43 of the bolt 50 is located in the elongated groove 14. By providing the elongated groove 14, the displacement range of the adjusting sleeve 30 can be limited, avoiding excessive displacement.

[0025] This application also provides a gear 200 inspection device, including the aforementioned assembly shaft 100 and an inspection probe located in the assembly groove. The base 10 of the assembly shaft 100 has recessed pin holes 15 on both end faces to engage with the pins of the gear 200 inspection device to fix the assembly shaft 100. Using this assembly shaft 100 helps reduce the cost and maintenance difficulty of the inspection device.

[0026] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0027] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
