Description

Technical Field

[0001] The utility model belongs to the technical field of winding devices and relates to an automatic winding device for a motor rotor of a cooling fan of an automobile. Background Art

[0002] The motor rotor is the rotating part in the motor. The motor consists of two parts: the rotor and the stator. It is a device used to realize the conversion of electrical energy into mechanical energy and mechanical energy into electrical energy. The motor rotor is divided into two types: inner rotor rotation mode and outer rotor rotation mode. The inner rotor rotation mode is that the core in the middle of the motor is the rotating body. The outer rotor rotation mode is that the outer body of the motor is the rotating body. Different modes facilitate the application of various occasions. During production and processing, the enameled wire needs to be wound on the rotor through a winding mechanism. A tension system is set at one end of the winding mechanism to adjust the tension of the enameled wire so that the enameled wire is evenly wound on the rotor. Several sets of pulleys are set in the tension system for routing. At the same time, a connecting rod is set at the top to control the tension of the enameled wire. The support rod pulls the connecting rod through the tension spring. The tension of the middle enameled wire is different when processing different rotors.

[0003] When winding the existing rotor, the ordinary adjustment block is generally fixed on the support rod, so that the tension spring is always in a certain stretched state. Processing different rotors requires pulling the enameled wire to different degrees, so that the cross bar rotates to different amplitudes. At the same time, the elastic force of the tension spring pulls the cross bar in the opposite direction to keep the enameled wire in a tensioned state. Since the tension spring itself is in a stretched state under the action of the gravity of the cross bar, it is very likely that an imbalance of traction and elastic force will occur when processing different rotors, causing the enameled wire to deform and break.

[0027] In this embodiment, the winding chamber 2 and the tension system 3 are existing equipment used in the rotor winding process, and the support rod 4 thereof pulls the cross bar 5 through the tension spring 42, and the clamp block 32 is also an existing structure in the tension system 3. When the enameled wire is pulled, the cross bar 5 makes a circular motion at the clamp block 32, and the distance between the device for fixing the rotor in the winding chamber 2 and the tension system 3 is unchanged. When processing different rotors, the enameled wire will be pulled to the right to different degrees, and then the cross bar 5 will also rotate to different degrees, during which the tension spring 42 will also be stretched accordingly.

[0028] Combination Figure 1 , Figure 2As shown, the connecting rod 41 is located at the front of the tension system 3, and the other end of the tension spring 42 is connected to the pin 62. The slide rail 51 is symmetrically arranged on the cross bar 5, and a pulley is installed at the right end of the cross bar 5. The cross bar 5 is inserted in the No. 1 cavity 7, and the limit column 31 can limit the movement range of the cross bar 5.

[0029] Furthermore, a plurality of pulleys are provided on the tension system 3, and the enameled wire is staggered around the corresponding pulleys and finally leads to the winding chamber 2 through the pulley at the end of the cross bar 5. In the winding chamber 2, there is a corresponding device to pull the enameled wire. Each movement of the traction device will cause the enameled wire to be tightened and then the cross bar 5 will move in a circular motion, and the tension spring 42 will also be deformed accordingly.

[0030] Combination Figure 1 , Figure 2 As shown, the pin shaft 62 and the opening 61 are rotatably connected, and the limiting ring 63 is symmetrically installed in the middle of the pin shaft 62, and there is a distance between adjacent limiting rings 63.

[0031] Furthermore, the pin shaft 62 is rotatably installed at the opening 61 , and a limiting ring 63 is provided on the pin shaft 62 . The rotating pin shaft 62 can reduce the friction loss with the tension spring 42 , and the limiting ring 63 can allow the tension spring 42 to move left and right on the pin shaft 62 .

[0032] Combination Figure 2 , Figure 4 As shown, the size of the No. 1 cavity 7 is larger than the cross bar 5, the No. 1 cavity 7 and the No. 2 cavity 71 are located on the same vertical line, and the No. 2 cavity 71 and the No. 3 cavity 72 are located on the same horizontal line. The No. 1 cavity 7 and the No. 2 cavity 71 are connected, the No. 2 cavity 71 and the No. 3 cavity 72 are connected, and the No. 3 cavity 72 is symmetrically arranged at both ends of the No. 2 cavity 71. The slider 74 is slidably connected to the slide rail 51, the movable block 8 is slidably connected to the No. 3 cavity 72, and the length of the movable block 8 is greater than the No. 3 cavity 72, and the sliding rod 82 is slidably connected to the through hole 81. There is a gap between the sliding rod 82 and the bottom of the through hole 81, the diameter of the spring 83 is greater than the through hole 81, the left end of the sliding rod 82 is connected to the support block 73, and one end of the spring 83 is connected to the outer wall of the support block 73. The limit block 84 extends to the tooth block 53, and the limit block 84 is smaller than the size of the area between adjacent tooth blocks 53.

[0033] Furthermore, the length of the movable block 8 is greater than that of the third cavity 72 so that one end thereof can protrude from the adjusting block 6, thereby facilitating pressing the movable block 8; there is a spacing between the slide bar 82 and the bottom of the through hole 81, and the slide bar 82 can move into the through hole 81 when the movable block 8 is pressed; the limit block 84 is smaller than the size of the area between adjacent tooth blocks 53, which means that the limit block 84 can be inserted between adjacent tooth blocks 53, thereby fixing the adjusting block 6 on the cross bar 5.

[0034] Combination Figure 2 , Figure 4 As shown, the distance between the sliding rod 82 and the bottom of the through hole 81 is greater than the length of the tooth block 53 .

[0035] Furthermore, the distance between the slide bar 82 and the through hole 81 is greater than the length of the tooth block 53. When the movable block 8 is pressed, there is enough distance inside the through hole 81 for the movable block 8 to move, thereby separating the limit block 84 and the tooth block 53.

[0036] The working principle of the utility model is:

[0037] The winding chamber 2 and tension system 3 in this case are existing mechanisms for winding the rotor of the cooling fan motor in automobile production. Therefore, the corresponding working methods and principles of the above two are not explained. In this case, corresponding changes are made to the adjustment block 6 on the cross bar 5. By changing the position of the adjustment block 6, the purpose of assisting in adjusting and controlling the tension of the enameled wire is achieved to avoid deformation and breakage of the enameled wire.

[0038] When it is necessary to adjust the position of the adjusting block 6, press the movable block 8 with two fingers to allow the movable block 8 to move along the No. 3 cavity 72, and then the sliding bar 82 moves toward the inside of the through hole 81, and the spring 83 is deformed and compressed to generate a deformation force. As the movable block 8 moves, the upper limit block 84 and the tooth block 53 are separated. After moving to the appropriate position, the pressing of the movable block 8 is stopped. Under the action of the spring 83, the movable block 8 moves outward along the No. 3 cavity 72, and the limit block 84 is again stuck between the corresponding tooth blocks 53. At this time, the adjusting block 6 can be moved on the cross bar 5 along the slide rail 51 through the slider 74. When processing rotors of different sizes, the position of the adjusting block 6 on the cross bar 5 is appropriately changed, so that the force arm of the tension spring 42 pulling the cross bar 5 changes accordingly. As the force arm changes, the tension spring 42 is in different pulling states, and the magnitude of the reverse elastic force generated is also different. Therefore, when processing different rotors, it is avoided that the elastic force of the tension spring 42 is unbalanced when pulling the enameled wire, and the enameled wire is prevented from deformation and breakage during winding.
