Description

Technical Field

[0001] The utility model relates to the technical field of motor coil winding, in particular to a skeleton structure for winding the coil of a three-phase asynchronous motor. Background Art

[0002] The three-phase asynchronous motor (also known as the three-phase induction motor) is a type of electric motor widely used in industries such as industry and agriculture. Its operating principle and structure are relatively simple, and it has good reliability and economy. The three-phase asynchronous motor uses three-phase alternating current as its power source. The three-phase power supply consists of three currents with a phase difference of 120 degrees, which can provide smoother operation. Unlike synchronous motors, the rotor speed of the asynchronous motor is not synchronized with the power supply frequency, that is, the rotor speed is lower than the synchronous speed of the motor. This difference is called slip. The three-phase asynchronous motor is an efficient, reliable and widely used type of motor. With its good performance and adaptability, it has become one of the indispensable power equipment in modern industry.

[0003] The existing process of winding the coil on the winding frame is usually very cumbersome, and there is no limit fixation measure for the coil that has been wound before it is completely wound. This causes the wound coil to fall off when the worker winds the coil next time, thereby reducing the worker's efficiency in winding the coil, and the coil may be offset, thereby affecting the final performance of the three-phase asynchronous motor.

[0004] Therefore, in order to solve the problems of the existing coil falling off and the low efficiency of coil winding, a skeleton structure for winding the coil of a three-phase asynchronous motor is needed to solve the above problems. Utility Model Content

[0008] As a further improvement of the present invention, the locking assembly includes a moving block located in the moving groove, the moving block is slidably connected in the moving groove, and a plurality of anti-slip protrusions are fixedly connected to the periphery of the moving block.

[0009] As a further improvement of the present invention, fixing holes are provided at both ends of the rubber ring, bolts are provided in the fixing holes, one end of the rubber ring is fixedly connected to the winding frame by the bolts, and the other end of the rubber ring is connected to the clamping block by the bolts.

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without making any creative efforts shall fall within the scope of protection of the present application.

[0025] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0026] In the description of this application, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the product of the application is usually placed when in use. It is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, it cannot be understood as a limitation on this application.

[0029] Example 1:

[0030] The outer wall of the winding frame 1 is provided with a plurality of winding grooves 4, and the outer wall of the winding frame 1 is provided with a plurality of movable grooves 9 and a plurality of clamping grooves 5. A movable block 2 is provided in the movable groove 9, and the movable block 2 is slidably connected in the movable groove 9. By moving the movable block 2 from one end of the movable groove 9 to the other end, the clamping block 6 can be limited. The outer periphery of the movable block 2 is fixedly connected with a plurality of anti-slip protrusions. By providing a plurality of anti-slip protrusions, the friction between the staff's hand and the movable block 2 can be increased, thereby facilitating the staff to slide the movable block 2. A clamping block 6 is provided in the clamping groove 5, and the rubber ring 3 can be installed by inserting the clamping block 6 into the clamping groove 5. A plurality of rubber rings 3 are provided at the front and rear ends of the winding frame 1. By providing a plurality of rubber rings 3, the coil wound on the winding frame 1 can be limited to prevent the coil from deviating when it is not fixed, thereby affecting the performance of the motor.

[0031] Example 2:

[0032] As one of the optimized structural designs for Example 1, Figure 2-Figure 4 As shown, both ends of the rubber ring 3 are provided with fixing holes, each of which is fitted with bolts 8. These fixing holes and the bolts 8 allow the rubber ring 3 to be secured to the winding frame 1 and to the clamping block 6. One end of the rubber ring 3 is fixedly connected to the winding frame 1 via the bolts 8, while the other end is connected to the clamping block 6 via the bolts 8. The outer periphery of the clamping block 6 is provided with a slot that matches the specifications of the movable block 2. By providing the slot and moving the movable block 2 into the slot, the movable block 2 can be used to position the clamping block 6, thereby securing the clamping block 6 within the clamping slot 5. A gasket 7 is provided on the inner periphery of the rubber ring 3 to reduce wear between the coil and the rubber ring 3, thereby extending the service life of the rubber ring 3 and, consequently, the motor. The specifications of the clamping slot 5 are compatible with the clamping block 6, and the rubber ring 3 can be installed by inserting the clamping block 6 into the clamping slot 5. The moving slot 9 and the clamping slot 5 are in communication. By making the moving slot 9 and the clamping slot 5 in communication, the moving block 2 can slide into the slot on the clamping block 6, thereby limiting the clamping block 6 by using the moving block 2.

[0033] Working principle: First, wind the coil on the winding frame 1. When the coil winding is completed, use the bolt 8 to fix one end of the rubber ring 3 on the winding frame 1, and fix the other end of the rubber ring 3 to the block 6. Then, insert the block 6 into the slot 5, and make the rubber ring 3 wrap the wound coil so that the rubber ring 3 can limit the coil. Then move the moving block 2 from one end of the moving slot 9 to the other end, and insert the moving block 2 into the slot on the block 6, so that the moving block 2 can limit the block 6, thereby preventing the block 6 from detaching from the slot 5 and ensuring the stability of the block 6 in the slot 5. By setting the gasket 7, the wear between the coil and the rubber ring 3 can be reduced, and the service life of the rubber ring 3 can be extended.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
