A combination device of large and small stators

Abstract

This invention relates to the field of fan motor technology, specifically to a large and small stator assembly device, including a machine base. The machine base has a lower fixture for supporting the large stator and an upper fixture for supporting the small stator. The upper fixture is driven to move up and down by a first vertical moving device, and the lower fixture is driven to move up and down by a second vertical moving device. This achieves the pressing of the small stator on the upper fixture and the large stator on the lower fixture. The first and second vertical moving devices, by setting a downward pressing stroke and retaining a margin, prevent the enameled wire on the small stator from breaking or the large and small stators from deforming. With this structural arrangement, the small stator on the upper fixture and the large stator on the lower fixture are pressed together, and the first and second vertical moving devices, by setting a downward pressing stroke and retaining a margin, prevent the enameled wire on the small stator from breaking or the large and small stators from deforming.

Description

Technical Field

[0001] This invention relates to the field of fan motor technology, and specifically to a combination device of large and small stators. Background Technology

[0002] As is well known, a fan motor can be divided into a rotor and a stator, and the stator can be further divided into a large stator and a small stator. In order to improve winding efficiency, the existing technology uses the method of first winding the small stator and then pressing the large stator and small stator together. The method is to fix the large stator and then directly press the small stator together with a cylinder. However, this method has defects and shortcomings such as the enameled wire being easily broken at the beginning, generating a lot of noise during production, and low work efficiency. In addition, existing stator assembly devices are mostly composed of pneumatic parts, which requires both electricity and air supply during production, which is very troublesome. Summary of the Invention

[0003] To address the above problems, the present invention provides a large and small stator combination device, which effectively solves the shortcomings of the prior art.

[0004] To achieve the above objectives, the technical solution applied in this invention is as follows:

[0005] A device for assembling large and small stators includes a machine base. The machine base is equipped with a lower fixture for supporting the large stator and an upper fixture for supporting the small stator. The upper fixture is driven to move up and down by a first up-and-down moving device, and the lower fixture is driven to move up and down by a second up-and-down moving device, thereby pressing the small stator on the upper fixture and the large stator on the lower fixture together. The first and second up-and-down moving devices are set with a downward pressing stroke and a margin to prevent the enameled wire on the small stator from breaking or the large and small stators from deforming.

[0006] According to the above scheme, the lower fixture is provided with large and small stator fixing seats. The large and small stator fixing seats are provided with a bottom cylinder, a middle cylinder and an upper cylinder. The outer diameter of the bottom cylinder is larger than the outer diameter of the large stator. The outer diameter of the middle cylinder is equal to the inner diameter of the large stator. The middle cylinder is provided with a large stator positioning pin. The outer diameter of the upper cylinder is equal to the inner diameter of the small stator. The upper cylinder is provided with a small stator positioning pin.

[0007] According to the above scheme, the large and small stator fixing seats are driven to move back and forth by a forward and backward moving device, so as to send the large and small stator fixing seats onto the lower fixture or send the large and small stator fixing seats out of the lower fixture.

[0008] According to the above scheme, the lower fixture is provided with insulating frame clamping block devices on both sides. The insulating frame clamping block devices are driven to move left and right by a driving member on the up and down moving device, so that the shape formed by the insulating frame clamping block devices on the left and right sides is equal to the inner diameter of the large stator.

[0009] According to the above scheme, the machine tool is also equipped with a sensor detector for detecting whether the large and small stators are in position and a grating device for confirming that the operator's hands have been removed.

[0010] According to the above scheme, the machine base is also equipped with a control unit for operating the up-down moving device 1, the up-down moving device 2, and the forward-backward moving device by means of electrical control.

[0011] According to the above scheme, the bottom of the machine tool is provided with multiple rollers for moving the machine tool and multiple positioning support feet for positioning the machine tool.

[0012] Beneficial effects of this invention:

[0013] The present invention employs a structure in which the large stator is mounted on the lower fixture and the small stator is mounted on the upper fixture. The lower fixture is driven to move the large stator upward by the second vertical moving device, and the upper fixture is driven to move the small stator downward by the first vertical moving device. This achieves the pressing of the small stator on the upper fixture and the large stator on the lower fixture. The first and second vertical moving devices are designed with a set pressing stroke and a margin to prevent the enameled wire on the small stator from breaking or the large and small stators from deforming.

[0021] The technical solution of the present invention will be described below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1 to 6 As shown, the present invention provides a large and small stator assembly device, including a machine base 10. The machine base 10 is provided with a lower fixture 11 for carrying the large stator and an upper fixture 12 for carrying the small stator. The upper fixture 12 is driven to move up and down by a vertical moving device 3, and the lower fixture 11 is driven to move up and down by a vertical moving device 2 13, so as to press the small stator on the upper fixture 12 and the large stator on the lower fixture 11 together. The vertical moving device 3 and the vertical moving device 2 13 prevent the enameled wire on the small stator from breaking or the large and small stators from deforming by setting the downward stroke and leaving a margin. With this structural arrangement, the large stator is mounted on the lower fixture 11, and the small stator is mounted on the upper fixture 12. The lower fixture 11 is driven upwards by the second vertical moving device 13, and the upper fixture 12 is driven downwards by the first vertical moving device 3, thus pressing the small stator on the upper fixture 12 and the large stator on the lower fixture 11 together. The first and second vertical moving devices 13 are configured with a set downward stroke and allowance to prevent the enameled wire on the small stator from breaking or the large and small stators from deforming. It should be noted that the stroke of the first and second vertical moving devices 13 can be adjusted according to the different stator sizes (different inner diameters and heights).

[0023] In this embodiment, the lower fixture 11 is provided with large and small stator fixing seats 6. The large and small stator fixing seats 6 are provided with a bottom cylinder 61, a middle cylinder 62 and an upper cylinder 63. The outer diameter of the bottom cylinder 61 is larger than the outer diameter of the large stator. The outer diameter of the middle cylinder 62 is equal to the inner diameter of the large stator. The middle cylinder 62 is provided with a large stator positioning pin 64. The outer diameter of the upper cylinder 63 is equal to the inner diameter of the small stator. The upper cylinder 63 is provided with a small stator positioning pin 65. With this structural arrangement, the outer diameter of the bottom cylinder 61 is larger than that of the large stator, protecting it from deformation due to impact. The outer diameter of the middle cylinder 62 is equal to the inner diameter of the large stator, securing it in place. The middle cylinder 62 has a large stator positioning pin 64 to confirm correct orientation. The outer diameter of the top cylinder 63 is equal to the inner diameter of the small stator, securing it in place. The top cylinder 63 also has a small stator positioning pin 65 to confirm correct orientation. In other words, this design prevents the large and small stators from shifting during the pressing process. It should be noted that the appropriate large and small stator fixing seats 6 can be replaced depending on the specific product (different inner diameters and heights of the stators).

[0024] In this embodiment, the large and small stator fixing seats 6 are driven to move back and forth by the forward and backward moving device 7, so as to feed the large and small stator fixing seats 6 onto the lower fixture 11 or to send the large and small stator fixing seats 6 off the lower fixture 11. With this structural arrangement, the forward and backward moving device 7 can feed the large and small stator fixing seats 6 onto the lower fixture 11, which facilitates the pressing of the small and large stators. After the pressing is completed, the forward and backward moving device 7 can send the large and small stator fixing seats 6 off the lower fixture 11, which is convenient for the operator to remove the finished product. That is to say, the forward and backward moving device 7 can move the large and small stator fixing seats 6 back and forth between the loading position and the pressing position. It should be noted that the stroke of the forward and backward moving device 7 can be adjusted according to the different products of the actual stator sizes (different inner diameters and heights).

[0025] In this embodiment, insulating frame clamping devices 1 are respectively provided on both sides of the lower fixture 11. The insulating frame clamping devices 1 are driven to move left and right by the driving member 2 provided on the vertical moving device 3, so that the shape formed by the insulating frame clamping devices 1 on the left and right sides is equal to the inner diameter of the large stator. With this structure, when the vertical moving device 3 presses down, it drives the driving member 2 to move the insulating frame clamping devices 1 on the left and right sides towards the middle, so that the shape formed by the insulating frame clamping devices 1 on the left and right sides is equal to the inner diameter of the large stator. This makes it easier to limit the small stator when the vertical moving device 3 drives the upper fixture 12 to move downward, so as to press the small stator into the large stator. In other words, since the outer diameter of the smaller stator is equal to the inner diameter of the larger stator, semi-circular grooves with the same inner diameter as the larger stator are provided on the left and right insulating frame clamping block devices 1. When the left and right insulating frame clamping block devices 1 are closed towards the center, the semi-circular grooves on the left and right insulating frame clamping block devices 1 form a circular hole with the same inner diameter as the larger stator. In practical applications, when the up-and-down moving device 3 presses down, the driving component 2 drives the left and right insulating frame clamping block devices 1 to move towards the center, saving one set of power devices. It should be noted that the corresponding clamping blocks can be replaced according to different products of different stator sizes (different inner diameters and heights).

[0026] In this embodiment, the machine 10 is also equipped with a sensor for detecting whether the large and small stators are in the correct position, and a grating device 8 for confirming that the operator's hands have been removed. This structural arrangement allows the sensor to detect whether the large and small stators are in the correct position, increasing product output and enhancing the practicality of the device. The grating device 8 confirms that the operator's hands have been removed, preventing their hands from being crushed and improving safety.

[0027] In this embodiment, the machine base 10 is also equipped with a control unit 9 for electrically operating the vertical moving device 3, the vertical moving device 13, and the forward and backward moving device 7. This structural arrangement, with electrical control, reduces the need for gas and oil distribution devices, saves costs, and lowers noise, increasing the practicality and environmental friendliness of the device.

[0028] In this embodiment, the bottom of the machine platform 10 is provided with multiple rollers 4 for moving the machine platform 10 and multiple positioning support feet 5 for positioning the machine platform 10. With this structural arrangement, the multiple rollers 4 facilitate the movement of the machine platform 10, and once in position, the multiple positioning support feet 5 achieve positioning of the machine platform 10. It should be noted that the positioning support feet 5 are height-adjustable.

[0029] The operation process of this invention:

[0030] 1) The operator first installs the large stator onto the lower fixture 11 on the machine base 10 according to the positioning direction;

[0031] 2) Then install the small stator on the upper fixture 12 on the machine tool 10 according to the positioning direction. The fixture has large and small stator fixing seats 6 and a sensor. The large and small stator fixing seats 6 have a large stator positioning pin 64 and a small stator positioning pin 65, so the large and small stators will not be offset.

[0032] 3) Once the sensor confirms that the stator has been positioned (a grating device 8 can be added to confirm that the operator's hands have been removed), the fixture will be automatically moved inward by the forward and backward moving device 7 until it is positioned.

[0033] 4) Next, the insulating frame clamping block device 1 slides inward so that the insulating frame clamping block device 1 is equal to the inner diameter of the large stator;

[0034] 5) The up-and-down moving device 13 and the up-and-down moving device 213 will press the wound small stator into the large stator. The up-and-down moving device 13 and the up-and-down moving device 213 have a set pressing stroke and a margin to prevent the enameled wire from breaking or the large and small stators from deforming.

[0035] 6) After being pressed into place, the forward and backward moving device 7 will automatically push the finished product outward;

[0036] 7) After the operator takes the finished product, the above actions can be repeated.

[0037] Compared to existing technologies, which previously involved three steps—mold entry, mold closing, and mold pressing—these steps have now been combined into one, saving considerable production time and improving work efficiency.

[0038] The technical solutions in the embodiments of the present invention have been described above. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims. All of these are within the scope of protection of the present invention.
