Technical Field

[0001] The utility model relates to the technical field of disassembly and assembly mechanisms, in particular to a portable motor disassembly and assembly mechanism. Background Technique

[0002] In the motor manufacturing industry, an electric motor, also known as a motor (commonly known as a motor), is represented by the letter "M" in a circuit (the old standard uses "D"). Its main function is to generate driving torque and serve as a power source for electrical appliances or various machines.

[0003] At present, the commonly used motor disassembly and assembly methods at home and abroad mostly rely on manual lifting or non-fixed disassembly. Manual lifting not only wastes manpower but also is not safe, easily causing safety accidents and having a great impact on production. Moreover, the operating space is limited and the environmental requirements are high. For non-fixed disassembly, using a general disassembly method, after removing the screws of the motor base, the motor base is placed on a certain plane, and the motor is moved manually or the plane is moved, driving the motor to move accordingly. During the movement, due to not being fixed, the motor is likely to fall or tilt, causing accidents and irreparable losses.

[0004] Therefore, it is urgent to design a portable motor disassembly and assembly mechanism to solve the above defects, which is particularly important. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the utility model designs a portable motor disassembly and assembly mechanism, which aims to solve the technical problems that the existing motor disassembly and assembly methods are inconvenient to operate manually, easily cause safety accidents, and non-fixed disassembly is likely to cause the motor to fall or tilt, resulting in accidents.

[0006] To achieve the above object, the utility model provides the following technical solutions:

[0007] A portable motor disassembly and assembly mechanism includes a frame. Buffer mechanisms are fixedly installed at both the left and right ends of the bottom of the frame. Mounting seats are fixedly installed at the bottoms of the two buffer mechanisms. Guide rails are fixedly installed at both the left and right ends inside the frame. A moving table is slidably connected between the two guide rails. A one-way lead screw is rotatably connected to the middle of the inner side of the frame. Limit frames are fixedly installed at both the front and rear ends of the top of the moving table. Positioning components are fixedly installed inside the two limit frames.

[0008] As a preferred solution of the utility model, the buffer mechanism includes a first sliding rod fixedly connected to the inside of the mounting seat. Buffer springs are sleeved at both the front and rear ends of the first sliding rod. Sliding sleeves are slidably connected to the outer side of the first sliding rod at the opposite ends of the two buffer springs. Transmission rods are rotatably connected to the tops of the two sliding sleeves. A connecting seat is installed between the two transmission rods, and the top of the connecting seat is fixedly connected to the frame.

[0009] As a preferred solution of the present utility model, a connecting sleeve is fixedly connected to the middle of the first sliding rod, a rubber buffer pad is fixedly connected to the outside of the connecting sleeve and below the connecting seat, and the tops of the two transmission rods are rotatably connected to the connecting seat.

[0010] As a preferred solution of the present utility model, the bottom of the moving table is slidably connected to the guide rail through a sliding seat, a hand wheel is fixedly connected to the front end of the one-way lead screw and on the front of the frame, a first lead screw nut is installed on the outside of the one-way lead screw, the outside of the first lead screw nut is fixedly connected to the bottom of the moving table through a nut seat, and both the front and rear ends of the one-way lead screw are rotatably connected to the frame through bearing seats.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. In the present utility model, through the design of the buffer mechanism, the frame is made according to the dimensions of the lifting vehicle and is fixed to the lifting vehicle through the mounting seat.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment:

[0023] Please refer to Figures 1 - 3 , the present utility model provides a technical solution:

[0024] A portable dismountable motor mechanism includes a frame 1. At the left and right ends of the bottom of the frame 1, buffer mechanisms 2 are fixedly installed. At the bottom of the two buffer mechanisms 2, mounting seats 3 are fixedly installed. At the left and right ends inside the frame 1, guide rails 4 are fixedly installed. A moving platform 5 is slidably connected between the two guide rails 4. At the middle of the inner side of the frame 1, a one-way lead screw 6 is rotatably connected. At the front and rear ends of the top of the moving platform 5, limit frames 7 are fixedly installed. Inside the two limit frames 7, positioning components 8 are fixedly installed.

[0025] First, the buffer mechanism 2 includes a first sliding rod 201 fixedly connected to the inner side of the mounting seat 3. Buffer springs 202 are sleeved on the front and rear ends of the first sliding rod 201. On the outer side of the first sliding rod 201 and at the opposite ends of the two buffer springs 202, sliding sleeves 203 are slidably connected. At the top of the two sliding sleeves 203, transmission rods 204 are rotatably connected. A connecting seat 205 is installed between the two transmission rods 204, and the top of the connecting seat 205 is fixedly connected to the frame 1. The frame 1 is made according to the size of the lift truck and is fixed on the lift truck through the mounting seat 3. When the lift truck moves to drive the motor, when the lift truck jolts, vibrations will be generated. The moving platform 5 pushes the transmission rod 204 under the connection of the connecting seat 205, causing the sliding sleeve 203 to slide on the outer side of the first sliding rod 201, so that the sliding sleeve 203 pushes the buffer spring 202 to buffer the vibrations. This not only improves the convenience of the motor dismounting and assembling process, but also ensures the stability of the motor dismounting and assembling process, avoiding damage to the motor.

[0026] Furthermore, a connecting sleeve 206 is fixedly connected to the middle of the first sliding rod 201. A rubber buffer pad 207 is fixedly connected to the outer side of the connecting sleeve 206 and below the connecting seat 205. The top ends of the two transmission rods 204 are rotatably connected to the connecting seat 205. When the connecting seat 205 moves downward, the outer side of the first sliding rod 201 is protected by the rubber buffer pad 207 on the outer side of the connecting sleeve 206, preventing the connecting seat 205 from hitting the first sliding rod 201 and being damaged.

[0027] Then, the bottom of the moving platform 5 is slidably connected to the guide rail 4 through a sliding seat 501. At the front end of the one-way lead screw 6 and on the front side of the frame 1, a hand wheel 601 is fixedly connected. A first lead screw nut 602 is installed on the outer side of the one-way lead screw 6. The outer side of the first lead screw nut 602 is fixedly connected to the bottom of the moving platform 5 through a nut seat 603. The front and rear ends of the one-way lead screw 6 are rotatably connected to the frame 1 through bearing seats 604. After placing the motor on the moving platform 5, the one-way lead screw 6 is rotated through the hand wheel 601 to make the first lead screw nut 602 move left and right. Under the connection of the nut seat 603, the motor on the top of the moving platform 5 is driven to move left and right. At the same time, when the moving platform 5 moves, the sliding seat 501 slides on the guide rail 4, supporting the motor and protecting and reducing the pressure on the one-way lead screw 6, improving its service life.

[0028] Secondly, the positioning component 8 includes a bidirectional lead screw 801 rotatably connected to the inner side of the limit frame 7. Second lead screw nuts 802 are installed at both the left and right ends of the bidirectional lead screw 801. A moving seat 803 is fixedly installed on the outer side of the second lead screw nut 802. The moving seat 803 is slidably connected to the limit frame 7 through a second slide bar 804. A positioning rod 805 is fixedly connected to the outer side of the moving seat 803. A crank 806 is fixedly connected to the right end of the bidirectional lead screw 801 and located outside the limit frame 7. A rubber sleeve 807 is sleeved on the outer side of the positioning rod 805. After placing the motor on the top of the moving platform 5, rotate the bidirectional lead screw 801 through the crank 806 to drive the two groups of second lead screw nuts 802 to move relatively. Under the sliding cooperation of the second slide bar 804, drive the moving seat 803 to move outward from the motor, use the positioning rod 805 to position and fix the outer side of the motor, and at the same time use the rubber sleeve 807 on the outer side of the positioning rod 805 to protect between the positioning rod 805 and the motor to prevent damage to the outer side of the motor. By positioning the outer side of the motor, the stability of the motor during the moving process is improved, and thus the safety of the motor disassembly and assembly is improved.

[0029] Finally, a fixed gear 808 is fixedly connected to the outer side of the crank 806. A pull rod 809 is slidably connected to the outer side of the limit frame 7. One end of the pull rod 809 close to the fixed gear 808 is engaged with the fixed gear 808 through a fixed tooth block 810. A return spring 811 is sleeved on the outer side of the pull rod 809 and located on the side where the fixed tooth block 810 is away from the fixed gear 808. The top end of the fixed tooth block 810 is slidably connected to the limit frame 7 through a slide post 812. When positioning the outer side of the motor, first pull the pull rod 809. Under the connection of the slide post 812, stably drive the fixed tooth block 810 to disengage from the fixed gear 808, thereby releasing the fixation of the crank 806. Then rotate the crank 806 to position the outer side of the motor. After the motor positioning is completed, release the pull rod 809. Under the extrusion of the return spring 811, the fixed tooth block 810 continuously fixes the fixed gear 808, thereby preventing the positioning rod 805 from loosening during the disassembly and assembly of the motor, and further ensuring the stability of the motor disassembly and assembly process.

[0030] In this embodiment, the implementation scenario is specifically as follows: The frame 1 is manufactured according to the size of the lifting vehicle and fixed to the lifting vehicle through the mounting seat 3. When the lifting vehicle moves with the motor driven, vibrations will be generated when the lifting vehicle jolts. The moving table 5 pushes the transmission rod 204 under the connection of the connecting seat 205, causing the sliding sleeve 203 to slide on the outside of the first sliding rod 201, so that the sliding sleeve 203 pushes the buffer spring 202 to buffer the vibrations. By rotating the one-way lead screw 6 with the handwheel 601, the first lead screw nut 602 moves left and right, and under the connection of the nut seat 603, the motor on the top of the moving table 5 is driven to move left and right. At the same time, when the moving table 5 moves, the sliding seat 501 slides on the guide rail 4, supporting the motor and protecting and reducing the pressure on the one-way lead screw 6, improving the service life. After the motor is placed on the top of the moving table 5, the two-way lead screw 801 is rotated by the crank 806, driving the two groups of second lead screw nuts 802 to move relatively. Under the sliding cooperation of the second sliding rod 804, the moving seat 803 is driven to move outward from the motor, and the outer side of the motor is positioned and fixed by the positioning rod 805. The whole operation process is simple and convenient. Compared with the existing motor disassembly and assembly methods, the present utility model can improve the overall convenience and stability of motor disassembly and assembly through the design, and improve the safety of motor disassembly and assembly.

[0031] Although the embodiments of the present utility model have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
