Description

Technical Field

[0001] The utility model relates to the technical field of nut installation equipment, in particular to a deep cavity nut positioning and installation mechanism. Background Art

[0002] Deep cavity nuts are nuts designed to be installed in deep cavities or enclosed housings, typically to secure bearings and other components. The design and installation of these nuts require special techniques and tools to ensure proper installation and locking in tight spaces.

[0003] Currently, installing nuts in deep cavities on parts presents two major challenges: First, deep-cavity nuts are prone to tilting during installation, causing the bolt to misalign with the nut's threaded hole, hindering installation. Second, the depth of deep cavities on parts varies, making nut positioning and installation extremely difficult. These factors lead to the widespread manual installation of deep-cavity nuts, resulting in low efficiency and high costs.

[0004] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a deep cavity nut positioning and delivery mechanism to solve the above problems.

[0005] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solution of the present invention and facilitating the understanding of those skilled in the art. It cannot be assumed that the above contents are well known to those skilled in the art simply because they are explained in the background technology of the present invention. Utility Model Content

[0006] In order to overcome the above-mentioned deficiencies in the prior art, the purpose of the present utility model is to disclose a deep cavity nut positioning and installation mechanism for solving the problem of difficulty in installing nuts in deep cavities of parts.

[0007] The utility model discloses a deep cavity nut positioning and delivery mechanism, comprising a base, a positioning platform and a pressing assembly. The base is provided with a plurality of guide posts and nut delivery push rods. The nut delivery push rods are used to deliver and confine the nut to be installed in the deep cavity of the part, so as to facilitate installation with the corresponding bolt. The guide posts and the nut delivery push rods both pass through the positioning platform and are slidably connected thereto, and the stable lifting and lowering of the positioning platform is ensured by the guide posts. A reset spring is provided on the outer periphery of the guide posts. The reset spring is located between the base and the positioning platform and is used to push the positioning platform upward so as to withdraw the nut delivery push rod from the deep cavity of the part, so as to facilitate the removal and placement of the assembled parts. A guide ejector pin is provided inside the nut delivery push rod so as to slide axially. An elastic member is provided below the guide ejector pin. The guide ejector pin guides and positions the nut to be installed from its inner ring, so as to prevent the nut to be installed from tilting during the process of entering the deep cavity of the part. At the same time, the spring at the lower end of the guide ejector pin prevents it from interfering with the bolt and nut during installation. A contoured positioning groove is provided at the upper end of the positioning platform for placing the parts, which is used to position and place the parts; a nut positioning groove is provided at the penetration position of the nut delivery push rod, which is used to position the nut so that it can correspond to the outer periphery of the deep cavity of the part; a convenient pressing rod is provided on the pressing assembly for restricting the parts and the positioning platform on the base.

[0008] Optimal technical solution: The height of the nut delivery push rod is adapted to the depth of the deep cavity at the corresponding position of the part, so that the deep cavity nut positioning and delivery mechanism can simultaneously deliver nuts to deep cavities of parts with different depths.

[0009] The preferred technical solution: the base includes a bottom plate, which is provided with a base pad for fixing the guide column and the nut delivery and installation ejector rod; the bottom plate is also provided with a fixing seat for fixing the pressing assembly, making the disassembly, assembly and maintenance of the deep cavity nut positioning and installation mechanism more convenient.

[0010] The preferred technical solution is as follows: the nut delivery ejector rod is a stepped columnar ejector rod, which facilitates the processing of an inner cavity inside the nut delivery ejector rod for the placement of the guide ejector pin and the elastic part; the positioning platform is provided with a corresponding stepped slide groove to avoid interference with the nut delivery ejector rod during the lifting and lowering process of the positioning platform.

[0011] Preferred technical solution: The elastic member is a spring, which provides stable elasticity and a large compressible stroke.

[0012] Preferred technical solution: A detachable limit piece is provided on the top of the guide column to prevent the positioning platform from exceeding the limit during the rising process and causing separation from the guide column.

[0013] Due to the application of the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0014] The utility model relates to a deep-cavity nut positioning and installation mechanism, which positions the nut and the part by arranging a contoured positioning groove and a nut positioning groove on a positioning platform, and facilitates the preliminary assembly of the nut and the deep-cavity opening of the part; a spring is used to control the distance between the positioning platform and the base, so as to avoid the part and the nut being affected by the nut installation ejector rod during the preliminary assembly; nut installation ejector rods of different heights are used in conjunction with the guide ejector pins slidably connected thereon to install the nut, so as to avoid the nut being not installed in place and tilting during the installation process; the above design makes the deep-cavity installation of the nut more convenient, improves its installation efficiency, and does not require manual positioning during the installation process, thereby reducing labor costs.

[0027] Example 1:

[0028] like Figure 1 As shown in the figure, a deep cavity nut positioning and feeding mechanism disclosed in the present invention includes a base 1, a positioning platform 2 and a pressing assembly 3. The main components are described in detail below:

[0029] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, two guide posts 11 and three nut delivery rods 12 are provided on the base 1; the guide posts 11 and the nut delivery rods 12 are all passed through the positioning platform 2 and are slidably connected thereto, and a detachable limit member 19 is provided on the top of the guide post 11 to prevent the positioning platform 2 from falling off from it; a reset spring 13 is provided on the outer periphery of the guide post 11; the reset spring 13 is located between the base 1 and the positioning platform 2 and is used to provide an upward thrust for the positioning platform 2; a guide pin 14 is provided inside the nut delivery rod 12 along the axial sliding direction, and an elastic member 15 is provided below the guide pin 14, which is used to pass through the The threaded hole of the nut 4 positions it to prevent the nut 4 to be installed from tilting in the deep cavity of the part during the installation process; the upper end of the positioning platform 2 is provided with a contoured positioning groove 21 for placing the part, and the contoured positioning groove 21 is used to quickly position and place the part; the contoured positioning groove 21 is provided with a nut positioning groove 22 at the penetration position of the nut delivery push rod 12, and the nut positioning groove 22 is used to position and place the nut 4 to be installed so that the corners of the nut 4 to be installed are aligned with the corners of the deep cavity of the part; the pressing component 3 is fixed on the base 1, and the pressing component 3 is provided with a convenient pressing rod 31 for restricting the part and the positioning platform 2 on the base 1.
