Description

Technical Field

[0001] This utility model relates to a disassembly and assembly tool, and more specifically, a special kit for flexible and efficient disassembly and assembly of rubber sleeves. Background Technology

[0002] Cigarette manufacturing lines widely employ spring-loaded vibrating troughs for loosening and conveying materials. The eccentric linkage mechanism of the spring-loaded vibrating trough connects to both the trough body and the balance body via rubber sleeves. Because the rubber sleeves are assembled with an interference fit, maintenance personnel, without specialized tools, will find disassembly and assembly time-consuming and laborious, and are highly susceptible to damage to the sleeve itself and its mounting surfaces. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model proposes a flexible and efficient kit for disassembling and assembling rubber sleeves, aiming to minimize the probability of damage to the rubber sleeves and the assembly surfaces of the equipment during maintenance and improve maintenance efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A flexible and efficient kit for assembling and disassembling rubber sleeves, wherein the rubber sleeves are coaxially assembled in the inner hole of the connecting rod, with an interference fit between them and the connecting rod. Its structural features are: The special kit includes a long screw, a fixing nut, a sleeve, an adjusting nut, a washer, and a push block; The sleeve has a hollow interior, with one end sealed by a sealing plate and the other end open. The sealing plate has a through hole coaxial with the sleeve. The push block has a through threaded hole in the center. The long screw has external threads, with a fixing nut fixed at one end and the other end threadedly assembled with the push block through the threaded hole. An adjusting nut is threaded on the rod body. The sleeve is coaxially fitted onto the long screw through the through hole. The end with the sealing plate can be tightened by the adjusting nut, and a washer is placed between the sleeve and the adjusting nut. The position on the long screw is adjustable. The special kit is used for disassembling and assembling rubber sleeves. A long screw can be movably inserted through the inner hole of the rubber sleeve. By adjusting the nut, the position of the sleeve is adjusted so that the open side of the sleeve surrounds the rubber sleeve and abuts against the side of the matching connecting rod along the axial direction of the rubber sleeve. The push block abuts against the rubber sleeve along the axial direction. The push block pushes the rubber sleeve along the axial direction by adjusting the threaded engagement between the nut and the long screw.

[0005] The structural features of this utility model also lie in: The outer diameter of the long screw is smaller than the inner diameter of the rubber sleeve to be removed, the inner diameter of the sleeve is larger than the outer diameter of the rubber sleeve to be removed, and the push block is a short cylindrical structure with an outer diameter smaller than the outer diameter of the rubber sleeve to be removed but larger than the inner diameter of the rubber sleeve to be removed.

[0006] The pusher is made of 45# steel.

[0007] The push block is covered with a rubber sleeve.

[0008] Rubber pads are installed at the parts of the sleeve that are in direct contact with the connecting rod.

[0009] Compared with existing technologies, the beneficial effects of this utility model are reflected in: Traditional rubber sleeve disassembly and assembly operations often use general-purpose maintenance tools to disassemble and assemble the rubber sleeve by axial hammering. This results in irregular and uneven point force on the rubber sleeve, which can easily damage the rubber sleeve and the assembly surfaces of the equipment. This utility model is a special tool for disassembling and assembling rubber sleeves. It utilizes the threaded engagement between the adjusting nut and the long screw, and the long screw, along with the push block, applies a uniform axial thrust to the rubber sleeve to complete the flexible disassembly and assembly. The disassembly and assembly is simple, efficient, time-saving, and labor-saving, and completely eliminates the risk of damage to the rubber sleeve, connecting rod, and related equipment and accessories caused by impact and vibration during the disassembly and assembly process.

[0012] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0013] The rubber sleeve 7 is coaxially assembled in the inner hole of the connecting rod, with an interference fit between it and the connecting rod. Please refer to [reference needed]. Figures 1 to 3 The special kit for flexible and efficient disassembly and assembly of rubber sleeves in this embodiment includes a long screw 1, a fixing nut 2, a sleeve 3, an adjusting nut 4, a washer 5, and a push block 6; The sleeve 3 has a hollow interior, with one end closed by a sealing plate 31 and the other end open. A through hole 32 coaxial with the sleeve 3 is provided on the sealing plate 31. A through threaded hole 61 is provided in the center of the push block 6. The long screw 1 has external threads, with a fixing nut 2 fixed at one end and the other end threadedly assembled with the push block 6 through the threaded hole 61. An adjusting nut 4 is threaded on the rod body. The sleeve 3 is coaxially fitted onto the long screw 1 through the through hole 32. The end with the sealing plate 31 can be pressed against by the adjusting nut 4, and a washer 5 is provided between the sleeve and the adjusting nut 4. The position of the sleeve on the long screw 1 is adjustable. When the special kit is used to disassemble and assemble the rubber sleeve 7, the long screw 1 can be movably inserted through the inner hole of the rubber sleeve 7. The position of the sleeve 3 is adjusted by adjusting the nut 4 so that the open side of the sleeve 3 surrounds the rubber sleeve 7 and abuts against the side of the matching connecting rod along the axial direction of the rubber sleeve 7. The push block 6 abuts against the rubber sleeve 7 along the axial direction. The push block 6 pushes the rubber sleeve 7 along the axial direction by adjusting the threaded engagement between the nut 4 and the long screw 1.

[0014] The structure of the special kit in this embodiment is further modified as follows: The outer diameter of the long screw 1 is smaller than the inner diameter of the rubber sleeve 7 to be removed, the inner diameter of the sleeve 3 is larger than the outer diameter of the rubber sleeve 7 to be removed, and the push block 6 is a short cylindrical structure with an outer diameter smaller than the outer diameter of the rubber sleeve 7 to be removed but larger than the inner diameter of the rubber sleeve 7 to be removed.

[0015] The push block 6, which is in direct contact with the rubber sleeve 7, is made of 45# steel. This is to protect the rubber sleeve 7 and the connecting rod during disassembly and assembly. The push block 6, which is in direct contact with the rubber sleeve 7, is entirely covered with a rubber sleeve 7.

[0016] Additionally, a rubber pad can be provided on the part of the sleeve 3 that is in direct contact with the connecting rod.

[0017] like Figure 4 As shown, the special kit for flexible and efficient disassembly and assembly of the rubber sleeve in this embodiment can be used to disassemble and assemble the rubber sleeve 7 in the following manner: First, assemble the specialized kit; The adjusting nut 4, washer 5, and sleeve 3 are sequentially fitted onto the long screw 1, and then the push block 6 is assembled to complete the assembly of the special set. Then remove and reinstall the rubber sleeve 7; Insert the long screw 1 through the inner hole of the sleeve 7 to be removed, and rotate the adjusting nut 4 to press against the sleeve 3. This pushes the sleeve 3 along the long screw 1 until the open end of the sleeve presses against the side of the connecting rod. Then, using a suitable wrench, continue rotating the adjusting nut 4, causing the long screw 1 to move axially along the through hole 32 of the sleeve 3, along with the push block 6. This causes the push block 6 to press against the sleeve 7 axially. Continue rotating the adjusting nut 4, using the push block 6 to generate a uniform axial thrust to push the sleeve 7, thus achieving flexible and efficient removal of the sleeve 7. The installation of the sleeve 7 and the connecting rod is similar and can be performed in the same manner.

[0018] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
