Description

Technical Field

[0001] The present invention relates to tobacco machinery, and in particular to an assembly and disassembly device. Background Art

[0002] The efficient operation and regular maintenance of mechanical equipment are essential. However, due to reasons such as bolt corrosion and over-tightening, the removal and installation of external nuts of mechanical equipment often become a bottleneck restricting maintenance efficiency and safety.

[0003] For example, the TG80 taff press is a fully automatic hydraulic taff press that compresses the dust collected by the dust removal equipment into a cylindrical, dense dust taff of a certain size. It is a commonly used mechanical equipment in tobacco production. The TG80 taff press is mainly composed of a frame, a storage bin, a spiral feed assembly, a dust pressing cylinder, a clamp and a hydraulic system.

[0004] like Figure 1 As shown, the clamp 1' of the TG80 type rod press is mainly composed of an upper clamping seat 11', a lower clamping seat 12' and two single-acting cylinder bodies 2'. The clamp 1' is generally installed on the forming head of the TG80 type rod press to clamp the forming head. The piston rod 21' in the cylinder body 2' passes through the upper clamping seat 11' and the lower clamping seat 12', and the upper clamping seat 11' and the lower clamping seat 12' are fastened together in the up and down direction by two left-right symmetrical nuts 101', so that the clamp 1' clamps the forming head and pushes out the compressed dense dust material rod through the forming head.

[0005] In actual production, the forming head is easy to be damaged and needs to be replaced and repaired frequently. Based on the structure of the above-mentioned clamp 1', to repair and replace the forming head, it is necessary to first remove the nut 101' of the clamp 1' to loosen the upper clamping seat 11' and the lower clamping seat 12', and the nut 101' needs to be installed after replacement. However, due to the poor working environment and high dust content of the clamp 1', dust will enter the threaded connection of the nut 101' and it is easy to rust. The traditional disassembly method uses a crescent wrench, and it is difficult to loosen the nut 101' using manpower. In addition, when installing the clamp 1' after maintenance, it is also difficult to tighten the nut 101' to the original tightness using a crescent wrench, which is inconvenient for frequent installation and removal of the nut 101'. Utility Model Content

[0006] The purpose of the present invention is to provide an assembly and disassembly device, aiming to solve the problem that it is difficult to manually assemble and disassemble the nuts of mechanical equipment using traditional disassembly tools.

[0007] A first aspect of the present disclosure provides an assembly and disassembly device for assembling and disassembling a nut, wherein the outer side surface of the nut includes a non-cylindrical surface, and the assembly and disassembly device includes: a nut sleeve, including an accommodating space, at least a portion of the inner wall of the accommodating space is matched in shape with at least a portion of the outer side surface of the nut including the non-cylindrical surface; and two or more handles, wherein the handles are connected to the outer side wall of the nut sleeve, and at least two of the two or more handles are spaced apart from each other along the circumference of the nut sleeve and have different lengths.

[0008] In some embodiments of the assembly and disassembly device, the length of at least one of the handles is configured to be adjustable.

[0009] In some embodiments of the assembly and disassembly device, at least one of the handles is detachably connected to the outer side wall of the nut sleeve.

[0010] In some embodiments of the assembly and disassembly device, the two or more handles are spaced apart from each other at the same distance along the circumferential direction of the outer side wall of the nut sleeve.

[0011] In some embodiments of the assembly and disassembly device, the inner wall of the accommodating space matches the outer wall of the nut in shape.

[0012] In some embodiments of the assembly and disassembly device, the outer wall of the nut has at least one strip-shaped groove extending along the thickness direction of the nut, and the inner wall of the nut sleeve is provided with at least one strip-shaped protrusion extending along the thickness direction of the nut sleeve, and the at least one strip-shaped protrusion is arranged corresponding to the at least one strip-shaped groove of the nut, and the at least one strip-shaped protrusion is matched in shape with the at least one strip-shaped groove.

[0013] In some embodiments of the assembly and disassembly device, the outer wall of the nut has at least one convex strip extending along the thickness direction of the nut, and the inner wall of the nut sleeve is provided with at least one groove along the thickness direction of the nut sleeve, and the at least one groove is arranged corresponding to the at least one convex strip of the nut, and the at least one groove matches the shape of the at least one convex strip.

[0014] In some embodiments of the assembly and disassembly device, the assembly and disassembly device further includes an auxiliary device, which is detachably connected to a side of at least one of the handles that is away from the nut sleeve.

[0015] Based on the assembly and disassembly device provided by the present disclosure, the assembly and disassembly device includes a nut sleeve and two or more handles, the inner wall of the accommodating space of the nut sleeve is matched with the outer side surface of the nut including at least part of the non-cylindrical surface, the handle is connected to the outer side wall of the nut sleeve, and at least two of the two or more handles are spaced apart from each other along the circumference of the nut and have different lengths. On the one hand, the structural setting of the inner wall of the accommodating space is conducive to the assembly and disassembly device to stably apply torque to the nut. On the other hand, at least two handles spaced apart from each other along the circumference of the nut sleeve are conducive to the user to assemble and disassemble the nut with both hands, which is convenient for the user to operate, and is also conducive to increasing the torque, thereby facilitating the assembly and disassembly of the nut on the mechanical device. In addition, setting more than two handles is conducive to allowing the user to apply force from different angles, especially in occasions where space is limited or torque needs to be applied from a specific angle. Setting at least two handles with different lengths is conducive to using a shorter handle to assemble and disassemble the nut when the position of the nut is not convenient for the longer handle to be assembled and disassembled, thereby facilitating the assembly and disassembly of the nuts arranged in pairs on the mechanical device or the nuts that are close to other structural positions.

[0030] The present disclosure provides an assembly and disassembly device for assembling and disassembling Figure 3 The nut 101' is shown. The outer side surface of the nut 101' includes a non-cylindrical surface. The assembly and disassembly device includes: a nut sleeve 11 and two or more handles 12. The nut sleeve 11 includes an accommodating space, and the inner wall of the accommodating space matches the shape of the outer side surface of the nut 101' including at least a portion of the non-cylindrical surface. The handle 12 is connected to the outer side wall of the nut sleeve 11, and at least two of the two or more handles 12 are spaced apart from each other along the circumference of the nut 101' and have different lengths.

[0031] The assembly and disassembly device of the disclosed embodiment includes a nut sleeve 11 and two or more handles 12. The inner wall of the accommodating space of the nut sleeve 11 matches the outer side surface of the nut 101' including at least part of the non-cylindrical surface. The handle 12 is connected to the outer side wall of the nut sleeve 11, and at least two of the two or more handles 12 are spaced apart from each other along the circumference of the nut sleeve 11 and have different lengths. On the one hand, the setting of the inner wall of the accommodating space is conducive to the assembly and disassembly device to stably apply torque to the nut 101'. On the other hand, at least two handles 12 spaced apart from each other along the circumference of the nut sleeve 11 are conducive to the user to assemble and disassemble the nut 101' with both hands, which is convenient for the user to operate and is also conducive to increasing the torque, thereby facilitating the assembly and disassembly of the nut 101' on mechanical equipment, especially large mechanical equipment. In addition, the provision of two or more handles 12 is conducive to allowing the user to apply force from different angles, especially in situations where space is limited or torque needs to be applied from a specific angle. Providing at least two handles 12 with different lengths is beneficial for using a shorter handle 12 to install and remove the nut 101' when the position of the nut 101' is not convenient for installing and removing a longer handle 12, thereby facilitating the installation and removal of nuts 101' arranged in pairs on mechanical equipment or nuts 101' located close to other structures.

[0032] In some embodiments, the handle 12 may be a straight handle, a curved handle, or any other structure that can be held by a user. Providing two or more handles 12 is not only convenient for the user to operate with both hands, but also convenient for multiple users to simultaneously install and remove the nut 101' to increase the torque, thereby facilitating the effective installation and removal of the nut 101' of the mechanical device and improving the installation and removal efficiency.

[0033] In some embodiments, the accommodation space of the nut sleeve 11 can be as follows: Figure 4 The through hole along the thickness direction of the nut sleeve 11 shown in the figure can avoid limiting the use direction of the assembly and disassembly device, so that the nut 101' can enter the accommodating space from any side of the two sides of the hole, which is conducive to accelerating assembly and disassembly. In other embodiments, the accommodating space of the nut sleeve 11 can also be a hole with one end opening along the thickness direction of the nut sleeve 11, so as to facilitate positioning of the nut 101' in the accommodating space, so as to limit the freedom of the nut 101' along the thickness direction of the nut sleeve 11, thereby facilitating the user to apply torque to the nut 101' more stably.

[0034] In some embodiments, the dimension of the accommodation space of the nut sleeve 11 along the thickness direction of the nut sleeve 11 may be greater than, less than, or equal to the thickness of the nut 101 ′.

[0035] In actual use, it is difficult for the user to apply only torque on the handle 12. Generally, the user will also apply force along the thickness direction of the nut sleeve 11, which will cause the assembly and disassembly device to move relative to the nut 101' along the thickness direction of the nut sleeve 11, which is easy to affect the assembly and disassembly effect. Setting the size of the accommodating space along the thickness direction of the nut sleeve 11 to be larger than the thickness of the nut 101' is conducive to maintaining the contact area between the inner wall of the nut sleeve 11 and the outer wall of the nut 101' during actual use, so as to facilitate the user to use the assembly and disassembly device to stably apply torque to the nut 101'. Especially for large-scale mechanical equipment, the size of the nut is generally large, which causes the size and weight of the matching assembly and disassembly device to increase accordingly, making it inconvenient to use and take and place. Setting the size of the accommodating space of the nut sleeve 11 along the thickness direction of the nut sleeve 11 to be less than or equal to the thickness of the nut 101' is conducive to facilitating production and manufacturing, reducing manufacturing costs, and also helping to reduce the weight of the assembly and disassembly device for easy handling by users.

[0036] In some embodiments, the length of at least one handle 12 is configured to be adjustable.

[0037] For example, the handle 12 may be configured to be retractable along the length direction of the handle 12. For another example, the handle 12 may also be composed of a plurality of handle units detachably connected along the length direction of the handle 12, so that the user can change the length of the handle 12 by adding or removing handle units. Both methods are conducive to conveniently and quickly adjusting the length of the handle 12.

[0038] Providing at least one handle 12 with an adjustable length is beneficial for lengthening the length of the handle 12 to increase the torque of the assembly and disassembly device on the nut 101', saving manpower, and is also beneficial for shortening the length of the handle 12 to prevent other devices and structures near the nut 101' from interfering with the movement of the handle 12 and affecting the assembly and disassembly efficiency of the assembly and disassembly device.

[0039] In some embodiments, at least one handle 12 is detachably connected to the outer side wall of the nut sleeve 11 .

[0040] This arrangement is conducive to replacing different types of nut sleeves 11 with the assembly and disassembly device, thereby facilitating the assembly and disassembly device to assemble and disassemble different types of nuts 101', thereby improving the applicable scope and operating efficiency of the assembly and disassembly device, and also facilitating improving the efficiency of manufacturing the assembly and disassembly device and saving manufacturing costs. In addition, this arrangement is conducive to quickly adjusting the number and style (length, shape, etc.) of the handles 12 connected to the nut sleeve 11, so that the assembly and disassembly device can adapt to various working spaces and forces.

[0041] In some embodiments, the two or more handles 12 are spaced apart from each other at the same distance along the circumferential direction of the outer side wall of the nut sleeve 11 .

[0042] For example, Figure 4 As shown, the assembly and disassembly device includes two handles 12 , and the two handles 12 are spaced 180° apart from each other along the circumferential direction of the outer side wall of the nut sleeve 11 (ie, the distance between them is the same).

[0043] This arrangement helps to distribute the force applied to the two or more handles 12 more evenly on the nut sleeve 11, reduces local stress concentration, helps to improve the efficiency of torque transmission, and helps to extend the service life of the assembly and disassembly device.

[0044] In some embodiments, the inner wall of the accommodating space matches the outer wall of the nut 101 ′ in shape.

[0045] This arrangement is beneficial to improving the stability of the assembly and disassembly device in use, and is beneficial for the user to evenly apply torque to the nut 101 ′ through the assembly and disassembly device.

[0046] In some embodiments, Figure 3 As shown, the outer wall of the nut 101' has at least one strip groove 101a extending in the thickness direction of the nut 101'. The inner wall of the nut sleeve 11 is provided with at least one strip protrusion 111 extending in the thickness direction of the nut sleeve 11. The at least one strip protrusion 111 is provided corresponding to the at least one strip groove 101a of the nut 101'. The at least one strip protrusion 111 is matched in shape with the at least one strip groove 101a.

[0047] In some embodiments, the outer wall of the nut has at least one convex strip extending in the direction of the thickness of the nut. The inner wall of the nut sleeve 11 is provided with at least one slot along the thickness direction of the nut sleeve 11, and the at least one slot is provided corresponding to the at least one convex strip of the nut. The at least one slot is matched with the at least one convex strip in shape.

[0048] Arranging at least one strip-shaped protrusion 111 of the nut sleeve 11 and at least one strip-shaped groove 101a of the nut 101' to be arranged correspondingly and in shape, or arranging at least one slot of the nut 11 and at least one protrusion of the nut to be arranged correspondingly and in shape, is conducive to improving the interaction force between the assembly and disassembly device and the nut to be assembled and disassembled, effectively transmitting the torque from the assembly and disassembly device to the nut to be assembled and disassembled, and preventing slipping during the process of tightening or loosening the nut, thereby facilitating improving the efficiency of the user to assemble and disassemble the nut using the assembly and disassembly device. In addition, this arrangement is conducive to guiding the nut, making it easy to quickly place the nut in the accommodating space of the nut sleeve 11.

[0049] In some embodiments, the assembly and disassembly device further comprises an auxiliary device which is detachably connected to a side of at least one handle 12 which is away from the nut sleeve 11 .

[0050] This arrangement is beneficial to increasing the torque applied by the user, thereby saving manpower and improving work efficiency.

[0051] The following combination Figures 1 to 5 The assembly and disassembly device of the embodiment of the present disclosure is described in detail. The assembly and disassembly device of the embodiment of the present disclosure is used to assemble and disassemble Figure 3 The nut 101' shown in FIG. 1 can be installed on a Figure 1 and Figure 2 The clamp of the TG80 type rod press shown in FIG. Figure 1 The nut 101 is spaced apart from another nut 101' in the left-right direction as shown.

[0052] The nut 101 ′ is cylindrical in shape as a whole, and has four strip-shaped grooves 101 a extending along the thickness direction of the nut 101 ′ on its outer wall, and the four strip-shaped grooves 101 a are spaced 90 degrees apart from each other along the circumference of the nut 101 ′.

[0053] like Figure 4As shown, the assembly and disassembly device of this embodiment includes a nut sleeve 11, two handles 12 (a first handle 121 and a second handle 122) and an auxiliary device (not shown). The nut sleeve 11 is a hollow cylinder, and the inner wall of the nut sleeve 11 forms an accommodating space. The inner wall of the nut sleeve 11 includes four strip-shaped protrusions 111 extending along the thickness direction of the nut sleeve 11, and the four strip-shaped protrusions 111 are spaced 90 degrees from each other along the circumference of the nut sleeve 11, so that the inner wall of the nut sleeve 11 matches the shape of the outer wall of the nut 101'.

[0054] The first handle 121 and the second handle 122 are respectively connected to opposite sides of the outer side wall of the nut sleeve 11. The length of the first handle 121 is less than the length of the second handle 122. This arrangement is conducive to the first handle 121 rotating smoothly without being blocked by the other nut 101' when the assembly and disassembly device is used to assemble and disassemble one of the nuts 101', and at the same time, the torque of the assembly and disassembly device acting on the nut 101' is increased by the second handle 122.

[0055] The auxiliary device cooperates with the handle 12, so as to help extend the distance from the point of application of the force of the user on the handle 12 to the rotation center, so as to help increase the torque when the force size remains unchanged or maintain the torque unchanged to reduce the artificial force.

[0056] In another embodiment, the length of the first handle 121 is less than or equal to half of the distance between the two nuts 101 ′, so that it is convenient to use two assembly and disassembly devices to assemble and disassemble the two nuts 101 ′ at the same time, thereby improving assembly and disassembly efficiency.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present disclosure rather than to limit it. Although the present disclosure has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present disclosure can still be modified or some technical features can be replaced by equivalents, which should all be included in the scope of the technical solution for protection requested by the present disclosure.
