Description

Technical Field

[0001] This utility model relates to the field of tobacco equipment machinery technology, and in particular to a tooling for disassembling a ring-shaped locking nut. Background Technology

[0002] In the cigarette production process, the cigarette machine prints colored steel stamps on the cigarette paper using an ink spreader. The ink spreader mainly consists of an ink transfer roller, an ink transfer cylinder, an ink spreading roller, and an ink spreading roller. The ink transfer cylinder and the ink transfer roller are used to transfer and spread ink, while the ink spreading roller evenly coats the steel stamping roller with ink. Both the ink transfer roller and the ink spreading roller are elastically supported and eccentrically mounted, fixed to the eccentric flange by a ring locking nut. When there are defects in the steel stamp quality or when performing routine maintenance, it is necessary to disassemble each ink roller for cleaning. Because the ring locking nut of the ink roller has a left-hand thread structure, the tightening degree will become tighter and tighter during the production process, making disassembly very difficult. Currently, the common disassembly method used by operators is to use a screwdriver or hammer to tap the groove of the ring nut for disassembly. This disassembly method results in uneven force and is very easy to damage the locking nut, which may even damage the servo motor at the rear in severe cases.

[0003] In conclusion, developing a tooling for disassembling a ring-shaped locking nut is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a tooling for disassembling annular locking nuts, which solves the technical problem that annular locking nuts gradually tighten during the operation of a cigarette machine and are difficult to disassemble.

[0005] To achieve the above objectives, this utility model provides a tooling for disassembling annular locking nuts, comprising:

[0006] The first locking part has a locking tooth inside, which can engage with the groove on the edge of the annular locking nut to fix the annular locking nut to the first locking part. The first locking part has a first handle, which drives the first locking part to rotate.

[0007] The second locking part has a locking element threaded to its side wall. The second locking part and the eccentric flange cooperate with each other, and the locking element locks the relative positions of the two. The second locking part is provided with a second handle, and the second locking part can be fitted into the first locking part.

[0008] Preferably, there are two locking teeth, each symmetrically distributed at both ends of the diameter of the first locking part. The extension direction of the locking teeth is parallel to the axis of the first locking part, and the locking teeth are of the same length as the first locking part.

[0009] Preferably, the side wall of the first locking part is provided with an arc-shaped groove, the symmetry plane of the arc-shaped groove coincides with the symmetry plane of each locking tooth, a locking member can be inserted in the arc-shaped groove, and the locking member can slide in the arc-shaped groove, the arc corresponding to the arc angle is less than 180°.

[0010] Preferably, both the first locking part and the second locking part are cylindrical tubes, and the second locking part is provided with a top plate at one end, and a boss is provided on the top plate. The boss is coaxially arranged with the second locking part, and second handles are provided on both sides of the boss. The extension direction of the second handles is the diameter direction of the second locking part, and the extension direction of the first handles is the diameter direction of the first locking part.

[0011] Preferably, the inner cavity of the first locking part is fitted with an annular locking nut, and the inner cavity of the second locking part is fitted with an eccentric flange. After the locking part is screwed on, the locking part holds and fixes the eccentric flange.

[0012] Preferably, the diameter of the boss is smaller than the diameter of the second locking part, and the distance between the end face of the boss and the second locking part is greater than the length of the first locking part, so that after the first locking part and the second locking part are fitted together, the boss extends out of the port of the first locking part away from the annular locking nut.

[0013] Preferably, the first locking part is integrally formed with the first handle and the locking teeth, and the second locking part is integrally formed with the boss and the second handle.

[0014] Preferably, the second locking part has a plurality of threaded holes on its side wall that mate with the locking member, and the threaded holes are evenly arranged along the circumference of the second locking part.

The end of the locking member abuts against the side wall of the eccentric flange, locking the second locking part and the eccentric flange in position. Then, fit the first locking part on the outside of the second locking part. The first locking part is locked and fixed to the ring lock nut by snapping teeth. The operator holds the second handle with one hand to prevent the eccentric flange from rotating, and turns the first handle with the other hand. Since the eccentric flange is locked in position, the first locking part causes the ring lock nut and the eccentric flange to rotate relative to each other, thus disassembling the tightened ring lock nut.

[0017] The ring lock nut disassembly fixture provided in this application can quickly and easily disassemble the ring lock nut, improving work efficiency. Moreover, the disassembly method is gentle, extending the service life of the ring lock nut and the servo motor. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] This application provides a ring-shaped locking nut disassembly tool, which includes a first locking part 1. The inner wall of the first locking part 1 is provided with engaging teeth 11, which can engage with the grooves on the edge of the ring-shaped locking nut to fix the first locking part 1 to the ring-shaped locking nut. First handles 3 are provided at both ends of the outer wall of the first locking part 1. Turning the first handles 3 causes the first locking part 1 to rotate the ring-shaped locking nut. Furthermore, the ring-shaped locking nut disassembly tool also includes a second locking part 2. A locking element 5 is threadedly connected to the side wall of the second locking part 2. The inner cavity of the second locking part 2 can engage with the outer wall of an eccentric flange. Tightening the locking element 5 causes it to move towards the side extending into the inner cavity of the second locking part 2. The end of the locking element 5 abuts against the side wall of the eccentric flange within the inner cavity, thus locking the second locking part. Part 2 is fixedly connected to the eccentric flange. Second handles 4 are also provided at both ends of the side wall of the second locking part 2. The position of the eccentric flange can be locked by holding the second handles 4. When using this utility model to disassemble the annular locking nut, the inner cavity of the second locking part 2 is aligned with the eccentric flange, and then the locking member 5 is screwed on so that the end of the locking member 5 presses against the side wall of the eccentric flange, locking the position of the eccentric flange and the second locking part 2. The first locking part 1 is sleeved on the outer periphery of the second locking part 2, and the snap-fit ​​teeth 11 of the first locking part 1 are aligned with the groove of the annular locking nut and fixed. At this time, the second handle 4 is locked to prevent the eccentric flange from rotating when only the first handle 3 is rotated, which would cause the tightened annular locking nut to rotate and make it difficult to separate the eccentric flange from the annular locking nut. After fixing the position of the eccentric flange, the first handle 3 is turned to remove the annular locking nut from the eccentric flange.

[0025] Please refer to the instruction manual appendix. Figure 1The first handle 3 is symmetrically arranged at both ends of the diameter of the first locking part 1. The first handle 3 is arranged in this way to apply the maximum torque to the first locking part 1. Similarly, there are two locking teeth 11 in the inner cavity of the first locking part 1. The first handle 3 and the locking teeth 11 are located in the same plane, that is, each locking tooth 11 is symmetrically arranged at both ends of the diameter of the first locking part 1. The sum of the torques applied by each locking tooth 11 to the annular locking nut is the maximum, so that the first locking part 1 can be tightened more easily. Preferably, the extension direction of the locking teeth 11 is parallel to the axial direction of the first locking part 1, and the length of the locking teeth 11 is the same as the length of the first locking part 1. That is, both ends of the first locking part 1 can be engaged with the annular locking nut, making the disassembly operation more convenient.

[0026] Furthermore, an arc-shaped groove 12 is provided on the side wall of the first locking part 1. The extension direction of the arc-shaped groove 12 is the circumferential direction of the first locking part 1, and the symmetry plane of the arc-shaped groove 12 coincides with the symmetry plane of the locking tooth 11. The width of the arc-shaped groove 12 is slightly larger than the diameter of the locking member 5. The locking member 5 can be inserted into the arc-shaped groove 12 and can slide within the arc-shaped groove 12. Preferably, a plurality of threaded holes 6 that cooperate with the locking member 5 are provided on the outer wall of the second locking part 2. The threaded holes 6 are evenly arranged along the circumferential direction of the second locking part 2. When the first locking part 1 and the second locking part 2 are nested together and their end faces are flush, each threaded hole 6 corresponds to the arc-shaped groove 12, and the locking member 5 passes through the arc-shaped groove 12 and cooperates with the threaded hole 6.

[0027] Please refer to the instruction manual appendix. Figure 1 With appendix Figure 2 The arc angle corresponding to the arc groove 12 is less than 180° to avoid excessive extension of the arc groove 12, which would create a large gap and reduce the maximum torque load and service life of the first locking part 1. The arc angle between each adjacent threaded hole 6 is less than or equal to the arc angle of the arc groove 12. In one embodiment of this application, the disassembled annular locking nut is a left-handed nut. The second locking part 2 is connected to the eccentric flange, and the first locking part 1 is connected to the annular locking nut. At this time, the ports of the first locking part 1 and the second locking part 2 are on the same plane, and each threaded hole 6 corresponds to the position of the arc groove 12. The first locking part 1 is rotated to align the arc groove 12 towards the right-hand direction. One end is aligned with the threaded hole 6, and a locking element 5 is installed in the threaded hole 6. The locking element 5 abuts against the eccentric flange, locking the second locking part 2 to the eccentric flange. Hold the second handle 4 and rotate the first handle 3 to turn the annular locking nut. At the same time, the locking element 5 located in the arc groove 12 slides to the other end. If the annular locking nut is still tightly connected to the flange ring after being turned, unscrew the locking element 5. Rotate the second locking part 2 to align the threaded hole 6 adjacent in the right-hand direction with the end of the arc groove 12 in the right-hand direction again. Set the locking element 5 in the threaded hole 6 and repeat the above turning process until the annular locking nut can be easily unscrewed from the eccentric flange.

[0028] Preferably, both the first locking part 1 and the second locking part 2 are cylindrical, and the second locking part 2 is smaller than the first locking part 1. When the first locking part 1 and the second locking part 2 are nested together, relative rotation can occur between them, with the rotation axes coinciding. In addition, a top plate is provided at the end of the second locking part 2 facing away from the eccentric flange, and a boss 21 is provided on the end face of the top plate facing away from the second locking part 2. The boss 21 is coaxially arranged with the second locking part 2, and the straightness of the boss 21 is... The diameter is smaller than the diameter of the second locking part 2. A second handle 4 is provided on both sides of the end of the boss 21. The distance between the end face of the boss 21 away from the eccentric flange and the port of the second locking part 2 is greater than the length of the first locking part 1. That is, after the first locking part 1 is engaged with the annular locking nut and the second locking part 2 is engaged with the eccentric flange, the second locking handle located at the end of the boss 21 is located outside the first locking part 1. When disassembling the annular locking nut, the operator can more easily hold the first handle 3 to lock the position of the eccentric flange.

[0029] Preferably, the locking tooth 11 can be any one of a cuboid, cube, or cylinder. The first locking part 1 is integrally formed with the locking tooth 11 and the first handle 3, and the second locking part 2 is integrally formed with the boss 21 and the second handle 4, which ensures the load strength and service life of the annular locking nut disassembly tool.

[0030] The annular locking nut disassembly fixture provided by this utility model uses a second locking member 5 to fix the eccentric flange and a first locking member 5 to engage the annular locking nut. The annular locking nut is then unscrewed from the rotatable eccentric flange. During disassembly, this fixture ensures that the annular locking nut is subjected to more even force, enabling quick disassembly or installation of the annular locking nut, improving work efficiency and reducing labor intensity. At the same time, the good fit with the annular locking nut prevents deformation of the locking nut groove, extends the service life of the annular locking nut, and better protects the rear servo motor.

[0031] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0032] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
