Description

Technical Field

[0001] The utility model relates to the technical field of disassembly and assembly tools, in particular to an M5 large pressure plate connecting shaft disassembly and assembly device. Background Art

[0002] During the tobacco rod rolling and forming process, the working surface of the bottom plate of the cigarette gun is combined with the working surfaces of the cigarette tongue, small pressing plate and large pressing plate to form a rolling and forming channel. The cloth belt uses this channel as its running track, carrying the cigarette paper and the tobacco rod it supports. After three compressions and expansions by the cigarette tongue, small pressing plate and large pressing plate, the tobacco rod is gradually processed into a continuous tobacco rod that meets the circumferential specification requirements.

[0003] The large pressing plate is one of the important mechanisms for rolling tobacco rods. In order to reduce the temperature of the large pressing plate and maintain the continuous operation of the equipment and good circumferential quality, the large pressing plate of the M5 rolling press uses a water cooling device. During actual use, maintenance personnel found that there was a hidden danger of coolant leakage in the connecting shaft of the large pressing plate, and it was necessary to disassemble and maintain the large pressing plate regularly, such as Figure 1 As shown, the large pressure plate mainly includes connector A, connector B, connector C, connector D and connector E. There are many connectors. During the disassembly and installation of these connectors, the connectors are often not concentric with the connecting shaft F, resulting in installation difficulties. When disassembling the connecting shaft F, since the shaft and the connector fit tightly, it is necessary to use a copper rod and a hammer to knock out the connecting shaft F, which can easily damage the connecting shaft F and is time-consuming. In order to ensure that the connecting shaft F is not damaged and reduce maintenance time, it is urgently necessary to design an M5 large pressure plate connecting shaft disassembly and assembly device.

[0006] The fixing frame has coaxial through holes on both sides, and the area between the two through holes is a receiving groove, which is integrally matched with the large pressing plate. When in use, one end of the large pressing plate for mounting the connecting shaft (i.e., the end of each connecting member with a mounting hole) is located in the receiving groove;

[0007] A screw rod is arranged on the fixing frame and is coaxial with the through hole, one end of the screw rod facing the receiving groove is a connecting end, the connecting end is used to be connected to the connecting shaft, and the other end of the screw rod is a fixed end, which is used to limit the rotation of the screw rod;

[0026] The present invention is further described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0027] Example 1

[0028] like Figure 2 As shown, this embodiment provides an M5 large pressure plate connecting shaft disassembly and assembly device, including: a fixed frame 1, a screw rod 2 and a nut 3. The side view of the fixed frame 1 is L-shaped to adapt to the shape of the connecting member A, so that the accommodating groove 13 in the middle of the fixed frame 1 can accommodate the lower connecting member A. Coaxial through holes 11 are provided on both sides of the fixed frame 1, and the area between the two through holes is the accommodating groove 13. The front side of the fixed frame 1 is an opening, and the rear side is provided with a positioning plate 14. When in use, the positioning plate 14 is used as a baffle to fit the large pressure plate to determine the back position of the connecting member A. At the same time, under the action of the fixed frame 1, the connecting member A is restricted inside the accommodating groove 13.

[0029] The nut 3 is arranged outside the fixing frame 1, and is coaxial with the through hole 11. The screw rod 2 is threadedly connected with the nut 3. A limiting portion 21 and a connecting portion 22 are provided at one end of the screw rod 2 facing the receiving groove 13, and the other end is a fixed end 23. The limiting portion 21 is used to limit the distance of the screw rod 2 to withdraw, so as to prevent the screw rod 2 from withdrawing too much and separating from the nut 3, causing the screw rod 2 and the nut 3 to need to be reassembled. The connecting portion 22 is provided with an external thread, and its diameter is adapted to the screw hole of the connecting shaft F, and is used to connect the screw hole of the connecting shaft F, so that the connecting shaft F can be driven to move when the screw rod 2 moves in a straight line. The fixed end 23 is used to limit the radial rotation of the screw rod 2. In this embodiment, it is a clampable block. When fixed, a tool such as a wrench that can clamp the fixed end 23 can be used to prevent the screw rod 2 from rotating, so that the screw rod 2 can be driven to move in a straight line when the nut 3 rotates.

[0030] like Figure 3 As shown, a receiving box 12 is provided on one side of the fixed frame 1 close to the nut 3, and the nut 3 is located outside the receiving box 12. When the screw rod 2 is withdrawn, its limiting portion 21 and connecting portion 22 move into the receiving box 12, thereby avoiding interference of the connecting end of the screw rod 2 with the large pressure plate, so as to facilitate the connection between the fixed frame 1 and the large pressure plate.

[0031] like Figure 4-5 As shown, when installing the connecting shaft F, first simply assemble the connecting parts A, B, C, D and E into an assembly, and then place the fixing frame 1 on the assembled assembly, so that the connecting part A is completely placed in the receiving groove 13, and the mounting holes of the connecting parts B, C, D and E are partially located in the receiving groove 13, and the mounting holes of the connecting parts are as opposite to the through holes 11 of the fixing frame 1 as possible, and then fix the fixed end 23 of the screw rod 2 so that the screw rod 2 will not rotate radially, and then rotate the nut 3 so that the screw rod 2, which is restricted in radial rotation, can only move linearly along the axial direction, and then pass through the mounting holes of each connecting part (screw rod 2) in turn. When passing through each mounting hole in a straight line, it is necessary to pay attention to whether the screw rod 2 is aligned with the mounting hole. If it is not aligned, it is necessary to fine-tune the position of the connector), and finally extend it from the through hole 11 at the other end of the fixed frame 1, and then connect the connecting part 22 with the screw hole of the connecting shaft F, and then rotate the nut 3 in the opposite direction to gradually retract the screw rod 2, and at the same time drive the connecting shaft F to move in a straight line, so that the connecting shaft F passes through each mounting hole in turn. After the connecting shaft F is in place, disconnect the connecting shaft F from the screw rod 2 (after fixing the connecting shaft F, rotate the screw rod 2 to unscrew the connecting part 22 from the screw hole of the connecting shaft F), remove the fixed frame 1 to complete the installation of the connecting shaft F.
