Description

Technical Field

[0001] This utility model relates to the field of product assembly technology, and more specifically, to an assembly mechanism for assembling aluminum cylindrical products. Background Technology

[0002] Currently, in the manufacturing of electronic equipment such as computer server chassis, aluminum cylinder-type front and rear assembly structures are widely used due to their advantages of lightweight, high thermal conductivity and electromagnetic shielding performance. Such structures are usually composed of components such as front cylinder, relay connectors and rear fixing bases, and multi-section assembly is achieved through threaded fastening or snap-fit.

[0003] During assembly, threaded connections and locating pins are commonly used. Threaded connections rely on bolt and nut pairs for axial fixation, requiring precise control of tightening torque to prevent aluminum stripping. Locating pins require multiple cylindrical pins that engage with holes to achieve radial alignment, demanding extremely high machining precision, which increases assembly complexity and time costs. Therefore, a new type of aluminum cylinder assembly structure is needed that can achieve rapid alignment and reliable locking while reducing machining precision. Utility Model Content

[0004] The technical problem to be solved by this utility model is how to provide a new type of aluminum cylinder assembly structure that can achieve rapid alignment and reliable locking while reducing processing accuracy. In view of the above-mentioned defects of the prior art, an assembly mechanism for front and rear assembly of aluminum cylinder products is provided.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An assembly mechanism for assembling aluminum cylindrical products from the front and rear, comprising a cylindrical assembly body with openings at both ends;

[0007] A front cover that can be detachably connected to the front end of the assembly body has multiple inclined guide parts evenly arranged on the outer circumferential surface of the front cover, and a receiving part is provided on the inner wall of the front cover corresponding to each guide part.

[0008] A detachable rear cover is connected to the rear end of the assembly body. The side wall of the assembly body near the rear cover is provided with multiple limiting strips at intervals along the circumference. The rear cover is provided with limiting grooves corresponding to the limiting strips.

[0009] The inclined direction of the guide part matches the guide surface of the receiving part, which is used to push the front cover to move axially to the assembly position; the cooperation between the limiting strip and the limiting groove is used to restrict the circumferential degree of freedom of the rear cover to achieve rapid installation.

[0010] By adopting the above technical solution, during the assembly of the front cover, the cooperation between the guide part and the receiving part can effectively push the front cover to the assembly position, reducing unnecessary assembly steps. During the assembly of the rear cover, the rear cover can be installed simply by aligning the limiting strip with the limiting groove.

[0012] When the front cover is assembled with the main body, the fixing teeth are squeezed and compressed into the receiving groove. When the fixing teeth move to align with the mating groove, the spring spring drives the fixing teeth to embed into the mating groove to lock the front cover.

[0013] By adopting the above technical solution, during the process of pushing the front cover and the assembly body together, the guide part and the receiving part move relative to each other, the spring is squeezed by the fixing teeth, and the fixing teeth are squeezed and stored in the storage groove. When the front cover moves to the point where the fixing teeth correspond to the engagement groove, the spring pushes the fixing teeth into the engagement groove, thereby limiting the position of the front cover and enabling the front cover and the assembly body to be successfully assembled.

[0014] Preferably, the inner wall of the assembly body is provided with a plurality of assembly positions spaced circumferentially, and a hollow frustum-shaped connecting magnet is embedded in each assembly position. The inner sides of the front cover and the rear cover are provided with magnetic corresponding blocks corresponding to each connecting magnet, and the magnetic pole distribution of the corresponding blocks is complementary to the magnetic pole distribution of the connecting magnet.

[0016] Preferably, the assembly body has an annular receiving platform at the end near the rear cover, the outer wall of the receiving platform has an inclined guide surface, the side of the rear cover has an inclined portion, the end of the inclined guide surface has a positioning hole, and the end of the inclined portion has a snap-fit ​​portion that matches the positioning hole, the snap-fit ​​portion being an elastic protrusion.

[0017] By adopting the above technical solution, during the assembly of the back cover, the inclined part of the back cover is pushed to slide in accordance with the guide surface until the snap-fit ​​part is snapped into the positioning hole. This not only reinforces the back cover but also reduces the possibility of the back cover shifting during the assembly process, making the installation of the back cover more convenient and faster.

[0018] Preferably, annular buffer rings are fitted around the inner circumference of both ends of the assembly body, and annular sealing grooves are provided on the inner side of the buffer rings, with the sealing grooves covering the outer edge of the assembly position.

[0019] By adopting the above technical solution, the buffer ring can not only buffer the front and rear covers during the assembly process, reducing the collision between the front and rear covers and the assembly body, but also protect the assembly position, reduce electrochemical corrosion of the assembly position, and extend its service life.

[0020] Preferably, the outer periphery of the assembly body is provided with an anti-detachment component. The anti-detachment component includes a fixing groove opened in the circumferential direction and an extension portion provided on the outer periphery of the front cover. The extension portion is embedded in the fixing groove, and an installation gap is formed between the extension portion and the front cover body to engage with the side of the assembly body.

[0022] Preferably, the inner wall of the assembly body is provided with multiple reinforcing ridges along the circumferential direction, and the reinforcing ridges are distributed between adjacent assembly positions.

[0023] By adopting the above technical solution, the main body of the assembly can be effectively reinforced, reducing the deformation of the main body of the assembly.

[0024] Preferably, a connecting block is provided on the assembly position, the connecting block has a spiral groove in its axial direction, a spiral rod is correspondingly provided on the inner side of the front cover, the spiral rod is rotatably connected to the front cover through a bearing, and the thread of the spiral rod engages with the spiral groove.

[0025] By adopting the above technical solution, during the assembly of the front cover, the front cover is pushed so that the end of the spiral rod aligns with the opening of the spiral groove. The spiral rod rotates until it gradually fits tightly with the spiral groove. The spiral rod is then fixed by the fixing component to prevent the spiral rod from rotating during normal use of the equipment.

[0026] Preferably, the inner side of the front cover is provided with a rotating groove and a positioning groove communicating with the rotating groove. The end of the spiral rod is rotatably connected in the rotating groove. The end of the spiral rod is provided with a locking groove. A fixing pin is slidably connected in the positioning groove. The end of the fixing pin is inserted into the locking groove to restrict the rotation of the spiral rod.

[0027] By adopting the above technical solution, after the screw rod and the screw groove are tightly fitted, the screw rod is fixed by inserting a fixing pin into the locking groove, thereby restricting the rotation of the screw rod and making the connection between the screw rod and the screw groove even tighter.

[0028] Preferably, the end of the snap-fit ​​part is a hemispherical structure, and the inner wall of the positioning hole is provided with a concave surface that matches the snap-fit ​​part. The engagement of the snap-fit ​​part and the positioning hole forms a self-locking structure.
