[0002] A motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. As a power source for electrical appliances or various machines, its main function is to convert electrical energy into mechanical energy.
[0003] At present, the existing motors usually include an upper end cover and a lower end cover, the stator and the rotor are arranged inside the upper end cover and the lower end cover, an upper flange is arranged on the upper end cover, a lower flange is arranged on the lower end cover, and a plurality of through holes are opened on the upper flange and the lower flange. When assembling the motor, the upper flange and the lower flange can be fitted together so that the through holes are aligned, and then rivets are passed through to fix them. However, since the upper end cover and the lower end cover are not pre-positioned before fixing, the aligned through holes are easily offset under external force collision, resulting in skewness. When the through holes are skewed, passing the rivets through and fixing them is likely to cause deformation of the through holes, thereby causing unstable connection and making the structure of the motor unstable.

Then, due to the limitation of the second flange by the limiting cover, the second flange can only rotate relative to the first flange and cannot shift. Then, rotate the limiting cover so that the positioning piece rotates until it abuts against the stop piece. Due to the restriction of the stop piece on the positioning piece, the limiting cover cannot continue to rotate. At this time, the first through hole and the second through hole are exactly aligned and communicated, and the rivet can be directly passed through the first through hole and the second through hole for fixation. Since the first through hole and the second through hole are pre-positioned before connection, they are not easily deformed, thus ensuring the stable connection between the first flange and the second flange and the structural stability of the motor.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.
[0022] Please refer to Figure 1 、 Figure 2 As shown, a motor for kitchen appliances includes an upper end cover 1 and a lower end cover 2. Both the upper end cover 1 and the lower end cover 2 are made of stainless steel material, with high strength and hardness, and are corrosion-resistant, making the motor have better durability. A first flange 3 is provided on the upper end cover 1, and a second flange 4 is provided on the lower end cover 2. A number of first through holes 5 are formed in the first flange 3, and a number of second through holes 6 for communicating with the first through holes 5 are formed in the second flange 4. A limiting cover 7 for the second flange 4 to be embedded is provided on the first flange 3. A positioning piece 8 is provided on the inner peripheral wall of the limiting cover 7, and a stop piece 9 for abutting against the positioning piece 8 is provided on the second flange 4. When the positioning piece 8 abuts against the stop piece 9, the first through holes 5 and the second through holes 6 are aligned and communicated. Before combining the upper end cover 1 and the lower end cover 2, the first flange 3 and the second flange 4 can be first fitted together, so that the second flange 4 is embedded inside the limiting cover 7. Then, through the limitation of the second flange 4 by the limiting cover 7, the second flange 4 can only rotate relative to the first flange 3 and cannot shift. Then, the limiting cover 7 is rotated, so that the positioning piece 8 makes a circular motion accordingly until the positioning piece 8 abuts against the stop piece 9. Through the limitation of the positioning piece 8 by the stop piece 9, the limiting cover 7 cannot continue to rotate. At this time, the first through holes 5 and the second through holes 6 are exactly aligned and communicated, and the rivets can be directly passed through the first through holes 5 and the second through holes 6 for fixation. Since the first through holes 5 and the second through holes 6 are pre-positioned before connection, they are not easily deformed, thus ensuring the stable connection between the first flange 3 and the second flange 4 and the structural stability of the motor. Among them, a number of anti-slip ridges 17 are uniformly provided on the outer peripheral wall of the limiting cover 7, thus greatly increasing the friction coefficient on the outer peripheral wall of the limiting cover 7, making it not easy to slip when rotating the limiting cover 7, and the operation is relatively easy and convenient.
[0023] Please refer to Figures 3 - 5As shown, a positioning pin 10 is provided on the positioning piece 8, and a positioning hole 11 for the positioning pin 10 to penetrate is formed in the stop piece 9. When the positioning piece 8 abuts against the stop piece 9, the positioning pin 10 will penetrate through the positioning hole 11 accordingly. Through the limitation of the positioning pin 10 by the positioning hole 11, the connection between the positioning piece 8 and the stop piece 9 can be realized, and the separation between the positioning piece 8 and the stop piece 9 can be restricted, making the pre-positioning of the first through hole 5 and the second through hole 6 more stable. A threaded rod 12 is provided on the positioning pin 10, and a threaded sleeve 13 is threadedly connected to the threaded rod 12. After the positioning pin 10 penetrates through the positioning hole 11, the threaded rod 12 will penetrate through the positioning hole 11 accordingly. Then the threaded sleeve 13 can be threadedly connected to the threaded rod 12 until it abuts against the stop piece 9 to achieve locking, thereby realizing the stable connection between the positioning piece 8 and the stop piece 9 and preventing detachment, further improving the stability of the pre-positioning of the first through hole 5 and the second through hole 6. An elastic washer 14 is connected to the threaded sleeve 13, and the elastic washer 14 is made of rubber material. After the threaded sleeve 13 is threadedly connected to the threaded rod 12, the elastic washer 14 will abut against the stop piece 9 and generate elastic deformation, thus reversely applying a thrust to the threaded sleeve 13, making the threaded engagement between the threaded sleeve 13 and the threaded rod 12 more stable, thereby improving the firmness of the connection. An embedding groove 15 for the elastic washer 14 to be embedded is formed in the stop piece 9. Through the limitation of the elastic washer 14 by the embedding groove 15, the stability when the threaded sleeve 13 abuts against the stop piece 9 can be improved. Among them, a plurality of anti-slip grooves 16 are evenly formed on the outer peripheral wall of the threaded sleeve 13, thus greatly increasing the friction coefficient on the outer peripheral wall of the threaded sleeve 13. When screwing the threaded sleeve 13 to be threadedly connected to the threaded rod 12, it is not easy to slip, and the operation is relatively easy and labor-saving.
