Description

Technical Field

[0002] The rotor punching refers to a metal or plastic sheet fixed on the motor rotor, attached to the stator, and used to reduce the friction and wear between the rotor and the stator when the rotor rotates. It consists of two parts: a static ring and a dynamic ring. The static ring is installed on the inner shell of the motor, and the dynamic ring is fixed on the end face of the rotor. The main function of the rotor punching is to control the friction and wear of the rotor during operation. When the rotor rotates, because the gap between the rotor and the stator is very small, a lot of friction will be generated, which will cause energy loss, overheating of the motor and wear of mechanical parts. The role of the rotor punching is to adjust the position of the rotor within a small range through the friction of the static ring and the dynamic ring to ensure the normal operation of the motor. In addition, the rotor punching can also improve the efficiency of the motor.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 4 As shown, the utility model provides a loading and unloading device for rotor punching, including a box body 1, a motor 2 is fixedly connected to the bottom of the box body 1, support columns 3 are fixedly connected to the four corners of the bottom of the box body 1, the output end of the motor 2 passes through the interior of the box body 1 and is fixedly connected to a transmission shaft 4, a transmission assembly 5 is arranged at the bottom of the box body 1, a lifting assembly 6 is arranged inside the box body 1, and a limiting assembly 7 is arranged at the top of the box body 1.

[0022] refer to Figure 3 The transmission assembly 5 includes a driving gear 51, which is fixedly connected to the surface of the transmission shaft 4. A threaded rod 52 is slidably connected to the bottom of the inner wall of the box body 1. There are three threaded rods 52. A planetary gear 53 is fixedly connected to the bottom of the surface of the threaded rod 52. The planetary gear 53 is meshed with the driving gear 51.

[0023] As a technical optimization solution of the utility model, the setting of the transmission component 5 can make the loading and unloading operations after the installation and limiting are completed more convenient, avoiding the cost increase and resource waste caused by manual loading and unloading operations.

[0024] refer to Figure 2 The lifting assembly 6 includes a threaded sleeve rod 61 , which is threadedly connected to the surface of the threaded rod 52 , and a moving plate 62 is fixedly connected to the top of the threaded sleeve rod 61 .

[0025] As a technical optimization solution of the utility model, through the setting of the lifting component 6, the movable plate 62 can be lifted and lowered when the transmission component 5 is in operation, so as to complete the loading and unloading operations of the rotor that has been installed and limited on the top of the movable plate 62.

[0026] refer to Figure 4 The limiting assembly 7 includes an electric rod 71, which is fixedly connected to the top of the movable plate 62. The top of the electric rod 71 is fixedly connected to the limiting frame 72. The top of the limiting frame 72 is provided with a limiting hole 73. The top of the movable plate 62 is fixedly connected to a fixed block 74. There are four fixed blocks 74. Both sides of the fixed block 74 are slidably connected to the limiting plate 75 through a pin shaft. The top of the limiting plate 75 is slidably connected to the limiting column 76 through a pin shaft. The top of the surface of the limiting column 76 is slidably connected to the inside of the limiting hole 73. The top of the limiting column 76 is fixedly connected to the limiting block 77.

[0027] As a technical optimization scheme of the utility model, through the setting of the limit assembly 7, after the electric rod 71 is started, the electric rod 71 drives the limit frame 72 to move downward, so that the limit plate 75 flips and drives the limit column 76 and the limit block 77 to slide outward inside the limit hole 73, so that rotors of different sizes can be installed and limited, avoiding the situation that the original equipment cannot install and limit the rotor larger than the second through groove and the movable groove.

[0028] refer to Figure 3 A fixing groove 8 is provided at the bottom of the inner wall of the box body 1 , and the number of the fixing grooves 8 is three. The bottom of the threaded rod 52 is slidably connected to the inside of the fixing groove 8 .

[0029] As a technical optimization solution of the utility model, the threaded rod 52 can be limited by setting the fixed groove 8 to avoid position deviation when the threaded rod 52 rotates, which causes the planetary gear 53 at the bottom of the threaded rod 52 to be out of meshing with the driving gear 51.

[0030] refer to Figure 2 The bottom of the inner wall of the box body 1 is fixedly connected with a slide rod 9, the number of the slide rod 9 is three, and the top of the slide rod 9 penetrates to the top of the moving plate 62.

[0031] As a technical optimization solution of the utility model, the movable plate 62 can be positioned and fixed by setting the slide rod 9, thereby preventing the threaded sleeve 61 and the movable plate 62 from rotating with the threaded rod 52 and being unable to move up and down along the surface of the threaded rod 52.

[0032] refer to Figure 4 The outer side of the pin shaft is fixedly connected with a limit ring 10, and the limit ring 10 is used in conjunction with the limit assembly 7.

[0033] As a technical optimization solution of the utility model, through the setting of the limit ring 10, the limit plate 75 and the limit column 76 can be limited and fixed when the limit assembly 7 is running, so as to avoid the limit plate 75 and the limit column 76 being separated from the pin shaft surface when the limit assembly 7 is operating, causing the limit assembly 7 to stop running.

[0034] The working principle and use process of the utility model are as follows: when in use, the user first places the rotor to be installed and limited on the top of the limit block 77, starts the electric rod 71, and the electric rod 71 drives the limit frame 72 to move downward. When the limit frame 72 moves downward, the limit plate 75 flips over. When the limit plate 75 flips over, it drives the limit column 76 to slide outward inside the limit hole 73. When the limit column 76 slides outward inside the limit hole 73, it drives the limit block 77 to slide outward on the surface of the limit frame 72. Rotors of different sizes are installed and limited on the top of the limit block 77, and the motor 2 is started. The output end of 2 drives the driving gear 51 to start rotating. When the driving gear 51 rotates, it drives the meshing planetary gear 53 to rotate. When the planetary gear 53 rotates, it drives the threaded rod 52 to rotate inside the fixing groove 8. When the threaded rod 52 rotates, under the positioning and fixing action of the slide bar 9, the threaded sleeve rod 61 moves upward along the surface of the threaded rod 52. When the threaded sleeve rod 61 moves upward along the surface of the threaded rod 52, it drives the moving plate 62 to move upward. When the moving plate 62 moves upward, it drives the rotor that has been installed and limited to move upward, completing the loading and unloading operations of the rotor, and achieving the effect of efficient limiting.

[0035] To sum up: the loading and unloading device of the rotor punching sheet, through the box body 1, motor 2, support column 3, transmission shaft 4, transmission assembly 5, driving gear 51, threaded rod 52, planetary gear 53, lifting assembly 6, threaded sleeve rod 61, movable plate 62, limiting assembly 7, electric rod 71, limiting frame 72, limiting hole 73, fixed block 74, limiting plate 75, limiting column 76, limiting block 77, fixed groove 8, slide rod 9 and limiting ring 10, solves the problem that the operation process of the original equipment is too cumbersome when installing and limiting rotors of different sizes, and the rotors of different sizes that can be installed and limited are limited by the size of the second through slot and movable slot of the original equipment, and the rotor larger than the second through slot and movable slot cannot be installed and limited, which reduces the practicality and work efficiency.
