Description

Technical Field

[0001] The present application relates to the technical field of auxiliary tools, and in particular to a bolt idling prevention disassembly and assembly device. Background Art

[0002] In the process of production, cigarette enterprises need to use packaging machines to pack cigarette packs. The box mold in the packaging machine is used to complete the rotation and transportation of cigarette packs. Due to the operating conditions, the mold box is an important and easily worn and damaged component in the packaging machine. Figure 1 As shown, a partial structural diagram of the sixth wheel in the packaging machine is shown. The sixth wheel includes a top plate 1-1 and a bottom plate 1-2 spaced apart from each other. A box mold 1-3 is circumferentially arranged in the peripheral space between the top plate 1-1 and the bottom plate 1-2. The cigarette pack is placed in the cavity of the box mold 1-3. When the bottom plate 1-2 rotates, the box mold 1-3 is driven to rotate and transport the cigarette pack. During the long-term operation of the equipment, the box mold 1-3 is prone to wear and damage, so the box mold 1-3 needs to be replaced. One end of the bolt 1-4 connecting the box mold 1-3 and the bottom plate 1-2 extends out of the bottom of the bottom plate 1-2, and the other end of the bolt 1-4 extends into the box mold 1 -3, when the bolts 1-4 are tightened, for the bolts 1-4 extending into the inner part of the box mold 1-3, in actual circumstances, the top plate 1-1 will still be sealed, and only a small window is provided on the box mold 1-3, which is inconvenient for tools such as wrenches to enter. Only hands or small screwdrivers can be inserted through the small window on the box mold 1-3 to press or support the bolts 1-4 on the inner part to prevent the bolts 1-4 from idling. The anti-idling effect of hands or screwdrivers on the bolts 1-4 is limited, and the operation is inconvenient, resulting in a long time-consuming process for replacing the box mold 1-3, which affects production efficiency.

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0024] like Figure 2-Figure 5As shown, the embodiment of the present application provides a bolt idling prevention disassembly and assembly device, which is applied to the disassembly and assembly operation of bolts, and is more used with a function similar to that of a wrench, and is preferably used for the disassembly and assembly of bolts in a narrow space, such as in the YB45 small box packaging machine of a cigarette factory. The small box packaging machine is used to rotate and convey small box cigarette packs. The rotation and conveying of the cigarette packs are mainly achieved by the box mold 90. When the equipment runs for a long time, the box mold 90 will be damaged, and the box mold 90 must be replaced regularly. One end of the bolt fixing the box mold 90 is exposed, and the other end of the bolt is in the inner space of the box mold 90. Moreover, the box mold 90 has only a small window. When disassembling and assembling the bolt, only the small window can be used. The smaller window is used to operate that end of the bolt. Due to space limitations, people can only enter the narrow space manually to press the bolt, or use a tiny screwdriver to enter the narrow space to clamp the bolt. Both methods have a relatively poor limiting effect on the bolt. When screwing the exposed bolt, it is not possible to stably and effectively prevent the inner end of the bolt from idling, which affects the disassembly and assembly efficiency of the bolt, thereby affecting the replacement efficiency of the box mold 90 and also affecting the production efficiency. The anti-bolt idling disassembly and assembly device provided in the present application aims to improve the convenience of disassembly and assembly of the bolts of the box mold 90, and to facilitate the disassembly and assembly of the bolts in the above-mentioned narrow space, thereby improving the efficiency of replacing the box mold 90, thereby facilitating the improvement of production efficiency.

[0025] The anti-bolt idling disassembly and assembly device comprises a first connecting arm 100 and a second connecting arm 200, the first connecting arm 100 and the second connecting arm 200 are movably connected, a wrench opening 201 is arranged on the second connecting arm 200, and the wrench opening 201 can be engaged with a bolt cap or a nut to realize the limit position when the bolt is disassembled and assembled. Since the first connecting arm 100 and the second connecting arm 200 are movably connected, and the size of the second connecting arm 200 is preferably smaller than that of the first connecting arm 100, the second connecting arm 200 can be changed. The state of the first connecting arm 100, and thus the position and direction of the wrench opening 201 on the second connecting arm 200, can be changed, so that the second connecting arm 200 can be easily inserted into the inner space of the box mold 90, and the wrench opening 201 on the second connecting arm 200 and the bolt cap or nut can be engaged with each other to limit the tightening of the two ends of the bolt. The limiting of the bolt is more stable and effective, which is conducive to improving the disassembly and assembly efficiency of the bolt, thereby increasing the replacement speed of the box mold 90 and also helping to improve the production efficiency of the entire production line.

[0026] Preferably, the first connecting arm 100 has a first end and a second end, and the extension direction of the first end of the first connecting arm 100 is different from the extension direction of the second end of the first connecting arm 100. In the present embodiment, the first connecting arm 100 is an elongated member having a certain length, and the two ends along the length of the first connecting arm 100 are respectively the first end and the second end of the first connecting arm 100, and the second connecting arm 200 also has a first end and a second end, and the extension direction of the first end of the second connecting arm 200 is different from the extension direction of the second end of the second connecting arm 200. In the present embodiment, the second connecting arm 200 is an elongated member having a certain length, and the two ends along the length of the second connecting arm 200 are respectively the first end and the second end of the second connecting arm 200, and the first end of the second connecting arm 200 is constituted as a wrench opening 201, and the wrench opening 201 can be a dead end opening, a movable end opening, or a sleeve-type opening, etc. The second end of the second connecting arm 200 and the first end of the first connecting arm 100 The two ends of the first connecting arm 100 are hinged to each other so that the second connecting arm 200 can swing relative to the first connecting arm 100. Preferably, the line between the first end of the first connecting arm 100 and the second end of the first connecting arm 100 is not located in the swing plane of the second connecting arm 200 relative to the first connecting arm 100, that is, when the second connecting arm 200 swings relative to the first connecting arm 100, preferably, the second connecting arm 200 can swing around an axis relative to the first connecting arm 100. When the second connecting arm 200 and the first connecting arm 100 are folded in half, the second connecting arm 200 and the first connecting arm 100 are inclined to each other, and the line between the first end of the first connecting arm 100 and the second end of the first connecting arm 100 is not parallel to the line between the first end of the second connecting arm 200 and the second end of the second connecting arm 200. In this way, when the second connecting arm 200 is folded in half on different sides of the first connecting arm 100, the wrench opening 201 on the second connecting arm 200 is oriented in different directions, which is convenient for adaptation on different sides in a narrow space, so as to facilitate adaptation of the bolts.

[0027] Preferably, the first connecting arm 100 includes a first section 101 and a second section 102, and the first section 101, the second section 102 and the second connecting arm 200 are all elongated members with a certain length. One end of the first section 101 constitutes the first end of the first connecting arm 100 and is hingedly connected to the second end of the second connecting arm 200, the other end of the first section 101 is fixedly connected to one end of the second section 102, and the other end of the second section 102 constitutes the second end of the first connecting arm 100. The connecting line between one end of the first section 101 and the other end of the first section 101 is located in the swing plane of the second connecting arm 200 relative to the first section 101. More preferably, the first section 101 and the second section 102 are an integrally formed structure, and the first section 101 The angle between the connecting line at the two ends and the connecting line between the two ends of the second section 102 is less than 180 degrees and greater than or equal to 90 degrees, that is, the direction of the first section 101 and the direction of the second section 102 are not parallel, and the angle between the direction of the first section 101 and the direction of the second section 102 is less than 180 degrees and greater than or equal to 90 degrees. The second connecting arm 200 can swing around an axis relative to the first section 101. When the second connecting arm 200 and the first section 101 are folded in half, the direction of the second connecting arm 200 is parallel to the direction of the first section 101. In this way, when making the first connecting arm 100, the tilting and swinging angle of the second connecting arm 200 can be determined by the angle between the first section 101 and the second section 102, which is more convenient for limiting the bolts in a narrow space.

[0028] More preferably, a connecting rod 300 is arranged between the first section 101 and the second connecting arm 200, one end of the connecting rod 300 is hinged to the first section 101, and the other end of the connecting rod 300 is hinged to the second end of the second connecting arm 200. Under the action of the connecting rod 300, the second connecting arm 200 and the first section 101 can be more conveniently folded against each other, and the second connecting arm 200 and the first section 101 are misaligned, so as to facilitate the reverse limiting of the bolt. Figure 4 As shown, in another state, Figure 5 As shown, the second connecting arm 200 is folded to the other side relative to the first section 101, so that the inclination direction of the second connecting arm 200 relative to the first section 101 is changed, and the bolts on the other side of the narrow space can be limited. Figure 4 and Figure 5 The device is shown in two different states to limit the bolts at different positions in the packaging machine, so as to replace the box mold 90 of the packaging machine.

[0029] In this embodiment, the second connecting arm 200 can swing to a first preset position relative to the first section 101. In the first preset position, the line between the first end and the second end of the second connecting arm 200 is located in the first plane, the first section 101 and the second section 102 are located in the second plane, the first plane and the second plane are spaced apart and parallel to each other, so that the second connecting arm 200 is misaligned relative to the first connecting arm 100. The first preset position is a state in which the second connecting arm 200 and the first section 101 are folded against each other. In this embodiment, the second connecting arm 200 can also swing relative to the first section 101. By swinging to the second preset position, when in the second preset position, the line between the first end and the second end of the second connecting arm 200 is located in the third plane, and the third plane and the first plane are symmetrical with respect to the second plane. The second preset position is the other folded state of the second connecting arm 200 and the first section 101. By folding the second connecting arm 200 to different sides of the first section 101, the orientation of the second connecting arm 200 after being offset to one side of the first section 101 can be changed, so as to facilitate the adjustment of the position and orientation of the wrench opening 201, so as to limit the bolts at different positions in a narrow space.

[0030] In this embodiment, the second connecting arm 200, the connecting rod 300, the first section 101 and the second section 102 are all long components, which are convenient for extending into a narrow space. The swing plane of the second connecting arm 200 relative to the connecting rod 300 coincides with the swing plane of the connecting rod 300 relative to the first section 101. That is, during swing adjustment, the second connecting arm 200, the connecting rod 300 and the first section 101 are in the same swing plane to increase the torque stability and facilitate the limiting or tightening of the bolt. More preferably, the second connecting arm 200, the first section 101 and the second section 102 are all long plate-shaped components, the connecting rod 300 is also a long plate-shaped component, and the plane where the first connecting arm 100 is located and the plane where the second connecting arm 300 is located The plane where 200 is located is perpendicular to the swinging plane of the second connecting arm 200 relative to the first connecting arm 100. Taking a horizontal plane, the plane where the first section 101 and the second section 102 are located is parallel to the horizontal plane, the plane where the connecting rod 300 is located is perpendicular to the horizontal plane, the plane where the second connecting arm 200 is located is perpendicular to the plane where the connecting rod 300 is located, the second connecting arm 200 swings around the first axis relative to the connecting rod 300, and the connecting rod 300 swings around the second axis relative to the first section 101, the first axis and the second axis are parallel to each other, a first rotating shaft 41 can be set between the second connecting arm 200 and the connecting rod 300 for swing connection, and a second rotating shaft 42 can be set between the connecting rod and the first section 101 for swing connection.

[0031] In this embodiment, the distance between the axis of the first rotating shaft 41 and the axis of the second rotating shaft 42 is greater than the sum of the thickness of the first section 101 and the thickness of the second connecting arm 200, so that the first section 101 and the second connecting arm 200 can be folded in half. The length of the first section 101 is preferably equal to the length of the connecting rod 300, the length of the second connecting arm 200 is 1-3 times the length of the connecting rod 300, and the length of the second section 102 is 1-10 times the length of the first section 101, so that the second connecting arm 200 can be extended into a narrow space to limit the bolt. An enlarged end 5 can be set at the end of the second section 102 away from the first section 101. The width of the enlarged end 5 is greater than the width of the remaining area of ​​the first section 101, which is convenient for the operator to hold. A through hole 6 can also be set on the enlarged end 5, and the through hole 6 is convenient for hanging and storing the device. The enlarged end 5 has a circular outer cross-section, and the through hole 6 is also a hole with a circular cross-section, which makes the appearance smoother and improves the comfort of the operator's holding.
