Description

Technical Field

[0001] The utility model relates to the technical field of motor maintenance auxiliary equipment, in particular to a motor maintenance and disassembly tool. Background Art

[0002] After the motor of the cigarette conveyor chain plate runs for a long time, it is easy to cause the reducer seal ring to wear, the bearing on the shaft to be damaged, and the motor to leak oil. The requirements for high-altitude operations are strict and there are certain safety hazards. A lift is required for maintenance. Because the motor reducer shaft is rusted, the motor needs to be rust-proofed before disassembly. The motor can only be removed when the rust remover completely penetrates into the motor shaft and sleeve. A motor plus a reducer weighs about 160 pounds. Only two people can work on the lift car. A pad needs to be installed in the middle and fixed on the lift car at the same distance from the bottom of the motor. The lift is small, and there are restrictions on the disassembly, replacement, maintenance, and repair and installation of the motor. Without special tooling, the motor that is disassembled in one and a half hours often cannot be disassembled in three or four hours. Under normal circumstances, it cannot be repaired during production, because the multi-channel conveyor chain plates are on the same axis, and maintenance will cause a section of cigarette conveying to stop. Due to the lack of special tooling, the difficulty of motor disassembly and installation is often time-consuming and laborious. Therefore, how to conveniently and efficiently repair and disassemble the motor is of great significance. Utility Model Content

[0026] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present utility model, the embodiments of the present utility model are further described in detail below in conjunction with the accompanying drawings and implementation methods.

[0027] In view of the problems existing in the maintenance and disassembly of the motor of the current cigarette conveyor chain plate, the utility model provides a motor maintenance and disassembly tool to solve the problems of the existing motor maintenance and disassembly of the cigarette conveyor chain plate, such as inconvenient high-altitude work and long maintenance time and affecting production efficiency. The utility model can improve the efficiency of motor maintenance and disassembly and reduce the maintenance difficulty for maintenance personnel.

[0028] like Figures 1 to 6 As shown, a motor maintenance and disassembly tool comprises: a pull code disc 1 and a pull code screw 3. The pull code disc 1 is provided with a plurality of connecting through holes 11 and a central through hole, and the pull code disc 1 is detachably connected with the end face bolt of the motor reducer through the connecting through holes 11, and the central through hole is coaxially arranged with the fastening screw hole of the motor reducer shaft end face, and the aperture of the central through hole is larger than the aperture of the fastening screw, and the fastening screw hole is provided with a hexagon socket screw;

[0029] When the motor reducer is disassembled, one end of the code pulling screw 3 passes through the central through hole of the code pulling disc and is connected to the hexagonal groove on the top surface of the fastening screw, so that the motor 4 can be disengaged from the motor shaft 5 by rotating the code pulling screw.

[0030] Specifically, during maintenance and repair, the disc pull code is first connected and locked with the thread hole on the motor reducer through screws, and then the screw is screwed in. Since the motor weighs nearly 200 pounds, manpower cannot support its weight when it is disassembled. The motor end face adopts the principle of triangle non-deformation. As long as three M8×40 screws are locked on the motor end face, the motor can be disassembled by rotating the pull code screw. When maintenance and disassembly are required, the screws on the motor reducer shaft must be loosened first and then a hexagonal screw equal to the original screw is inserted to prevent the nut in the screw on the damaged shaft from being damaged. The six long holes on the disc correspond to the screw holes on the motor reducer, and are connected to the reducer end face through 3 M8×40 screws. The pull code screw thread is screwed in and contacts the groove of the hexagonal screw. As the screw is screwed in clockwise, the motor is separated from the motor shaft. Finally, the motor lands safely on the platform. This tooling can improve the efficiency of motor maintenance and disassembly and reduce the difficulty of maintenance personnel.

[0031] like Figure 2 As shown, the tooling also includes: a code pulling and pressing device 2; the code pulling and pressing device 2 is a flange structure, with a threaded through hole 23 in the middle, and the code pulling and pressing device includes: a tube neck 21 and a disc 22, the tube neck 21 matches the reducer shaft hole, the tube neck 21 and the disc 22 intersect vertically, and the threaded through hole 23 extends axially along the tube neck 21 and penetrates the disc 22. When installing the motor reducer, the code pulling and pressing device is threadedly connected to the code pulling screw through the threaded through hole, passed through the reducer shaft hole and screwed into the thread hole on the installation shaft, and the ratchet wrench is rotated to press the reducer onto the installation shaft.

[0032] In actual applications, when the reducer needs to be installed on the motor shaft, it is necessary to ensure that the reducer hole is at the same height as the shaft, and the keyway on the reducer corresponds to the keyway on the shaft. The pull-code pressing device is installed on the pull-code screw rod, and it is screwed into the threaded hole on the shaft through the reducer shaft hole. The reducer is pressed onto the shaft by rotating it with an M24 ratchet wrench. The installation process is as follows: place the motor on the platform in a straight line with the installed motor shaft, and the pull-code screw rod 3 passes through the pull-code pressing device 2 and enters the screw hole of the motor shaft to connect with it. The pull-code pressing device 2 rotates clockwise to tighten the outer circle of the motor shaft hole, and then the pull-code pressing device 2 is rotated clockwise with a ratchet wrench to allow the key on the motor shaft to smoothly enter the groove that matches the reducer hole until the motor is installed in place. This completes the installation of the motor.

[0033] Furthermore, the tube neck is a hexahedral tubular structure.

[0034] Furthermore, the connecting through hole has an elliptical cross section.

[0035] like Figure 5As shown, four connecting through holes 11 are arranged in a semicircular area of ​​the pull code disc 1, and the angle between two adjacent connecting through holes is 60°.

[0036] Furthermore, at least two of the connecting through holes are arranged in the other semicircular area of ​​the pull code disc.

[0037] Furthermore, the pulling screw 3 is an M16 screw.

[0038] like Figure 6 As shown, one end of the pull-code screw rod 3 is a pointed structure, and the other end of the pull-code screw rod 3 is a hexahedral structure.

[0039] Furthermore, the code pulling disc, the code pulling screw rod and the code pulling and pressing device are made of #45 steel.

[0040] It can be seen that the utility model provides a motor maintenance and disassembly tool, which adopts a pull code disc provided with multiple connecting through holes and a central through hole, and the pull code screw rod is threadedly connected to the pull code disc through the central through hole. When the motor reducer is disassembled, the pull code disc is connected and locked with the thread hole on the motor reducer by screws, and the motor reducer is removed from the connecting shaft by rotating the pull code screw rod. The existing problem of motor maintenance and disassembly of cigarette conveying chain plates, which is inconvenient and time-consuming in high-altitude operations, resulting in long maintenance time and affecting production efficiency, can improve the efficiency of motor maintenance and disassembly, and reduce the maintenance difficulty of maintenance personnel.

[0041] The above describes in detail the structure, features and effects of the utility model based on the embodiments shown in the drawings. The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation as shown in the drawings. Any changes made in accordance with the concept of the utility model, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and the drawings, should be within the protection scope of the utility model.
