Description

Technical Field

[0001] This utility model relates to motor stator processing equipment and a double-insertion paper protection mechanism for motor stator insulation paper. Background Technology

[0002] The insulating paper on the electronic stator wires plays a crucial role in the operation of the motor. Its main functions and purposes can be summarized as follows:

[0003] Electrical insulation (to prevent short circuits);

[0004] Core function: Isolate adjacent wires or windings to prevent short circuits or leakage caused by direct contact.

[0005] Dielectric strength: The insulating paper must have high dielectric strength to withstand the working voltage and prevent breakdown.

[0006] High temperature stability;

[0007] Thermal protection: The motor generates high temperatures during operation (especially in high-power or high-frequency scenarios), and the insulating paper must be able to withstand high temperatures (such as polyimide and other materials) to avoid melting or decomposition.

[0008] Long-term reliability: Maintains chemical stability at high temperatures, ensuring long-term insulation performance.

[0009] Mechanical protection;

[0010] Protection during winding process: During the manufacturing process, prevent physical damage to the conductor caused by friction, compression or vibration.

[0011] Structural support: Some insulating paper helps to fix the winding, maintain the shape of the coil, and enhance the overall structural stability.

[0012] The current stator wire needs to be twisted and shaped. During twisting, the deformation of the wire will damage the insulating paper wrapped around the stator wire.

[0013] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a double-insertion paper protection mechanism for motor stator insulation paper, making it more valuable for industrial applications. Utility Model Content

[0014] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a double insert paper protection mechanism for motor stator insulation paper.

[0015] This utility model discloses a double-insertion paper protector mechanism for motor stator insulation paper, including a support, a lower paper protector disc inside a through hole in the middle of the support, and an upper paper protector disc installed on top of the support.

[0016] The support has guide rails on both sides, and a transverse frame is mounted on the guide rails via a slider. A clamping cylinder is mounted on the transverse frame, and a pressure block is fixed on the telescopic rod of the clamping cylinder.

[0017] A double-insertion paper-protecting mechanism for motor stator insulation paper uses an upper paper-protecting disc and a lower paper-protecting disc to support and clamp the wire bundle on the stator wire. When the wire is twisted, the deformed part of the wire does not directly contact the insulation paper, thus protecting the insulation paper.

[0018] Furthermore, the lower protective paper tray includes a limiting plate that is recessed in the middle of the support. The limiting plate consists of multiple lower guide blocks arranged in a ring. The gap between the lower guide blocks is used to place multiple lower ejector pins. Each lower ejector pin has a vertical sliding post that is inserted into the corresponding arc-shaped groove in the lower turntable. Above the lower turntable is a lower cover plate fixed to the surface of the support.

[0019] The lower protective paper tray is used to clamp and position the lower end of the stator coil, facilitating the twisting operation of the wire.

[0020] Furthermore, a lower connecting rod is fixed to one side of the lower turntable. The end of the lower connecting rod has a waist-shaped groove. A lower connector is movably installed in the waist-shaped groove through a pin. The lower connector is fixedly connected to the telescopic rod of the lower cylinder. The lower cylinder is fixed to the support through an adapter block.

[0021] The lower turntable is driven by the lower cylinder to rotate, which in turn drives the lower ejector pin to be inserted between the wires, so as to facilitate the limiting of the lower end of the stator coil.

[0022] Furthermore, the upper paper tray includes an upper support plate for support, with a recessed limiting plate in the middle of the upper support plate. The limiting plate consists of multiple upper guide blocks arranged in a ring. The gaps between the upper guide blocks are used to place multiple upper ejector pins. Each upper ejector pin has a vertical sliding post, which is inserted into the corresponding arc-shaped groove in the upper turntable. Above the upper turntable is an upper cover plate fixed to the surface of the upper support plate.

[0023] The upper protective paper tray is used to clamp and position the upper end of the stator coil, facilitating the twisting operation of the wire.

[0024] Furthermore, an upper connecting rod is fixed to one side of the upper turntable. The end of the upper connecting rod has a waist-shaped groove. An upper connector is movably installed in the waist-shaped groove through a pin. The upper connector is fixedly connected to the telescopic rod of the upper cylinder. The upper cylinder is fixed to the upper support plate through an adapter block.

[0025] The upper turntable is driven by the lower cylinder to rotate, which in turn drives the upper pin to be inserted between the wires, so as to facilitate the limiting of the lower end of the stator coil.

[0026] Furthermore, four guide pillars are fixed on the support, and guide sleeves are fitted on the guide pillars at the four corners of the upper support plate. There are pads between the support and the upper support plate, and the pads are stuck in the slots on the lower side of the upper support plate.

[0027] The height of the upper support plate is adjustable to accommodate the processing needs of motor stators of different lengths.

[0028] Furthermore, a translation cylinder frame is fixed to one side of the support, and a translation cylinder is fixed on the translation cylinder frame. The telescopic rod of the translation cylinder is fixedly connected to the slider on the guide rail on one side.

[0029] The horizontal movement frame is moved back and forth by the translation cylinder, which makes it easy to adjust the relative position of the clamping cylinder and facilitates the clamping operation of the motor stator wire.

[0030] By means of the above solution, the present invention has at least the following advantages: This double-insertion paper protection mechanism for motor stator insulation paper drives the corresponding pins to extend through the upper and lower sets of paper protection discs, and they are locked between the corresponding wires of the motor stator. Subsequently, in conjunction with other wire twisting devices, the insulation paper protecting the wires will not be damaged during the twisting of the stator wires, thus achieving the purpose of protecting the insulation paper.

In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this invention are described in detail below with reference to the accompanying drawings.

[0041] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0042] See Figure 1 This type of motor stator insulation paper uses a double-insertion paper protection mechanism. The connecting rods at the four corners of the lower end of the support 1 are used for support and fixation. The upper end of the support 1 is a flat mounting plate. The lower paper protection plate 2 is installed in the circular through hole in the middle of the support 1. The lower paper protection plate 2 is used to clamp and limit the lower end of the stator wire. At the same time, there is an upper paper protection plate 3 above the support 1. The upper paper protection plate 3 is used to clamp and limit the upper end of the stator wire. By limiting the wire with the upper and lower sets of paper protection plates, the insulation paper protecting the wire will not be damaged when the wire is twisted and bent.

[0043] Meanwhile, a transverse frame 5 is movably mounted on the support 1 via a guide rail 4 and a slider. A clamping cylinder 6 is mounted on the transverse frame 5. The clamping cylinder 6 is used to drive the pressure block 7 to move down, which is used to assist in the clamping operation of the stator wire.

[0044] See Figures 2-4 The diagram shows the structure of the lower protective paper tray 2. There is a limiting plate in the middle of the support 1. The surface of the limiting plate is a ring of raised lower guide blocks 8. The lower ejector pins 9 are inserted into the gaps between adjacent lower guide blocks 8. The sliding pins on the lower ejector pins 9 are inserted into the arc-shaped grooves of the lower turntable 10. When the lower turntable 10 rotates, it can drive the lower ejector pins 9 to extend and retract. The lower ejector pins 9 can be inserted into the gaps between the stator wires and are located at the lower end of the insulating paper to provide protection for the lower insulating paper.

[0045] The lower turntable 10 is connected to the lower cylinder 13 via the lower connecting rod 11 and the lower connector 12. When the lower cylinder 13 is working, it can drive the lower turntable 10 to rotate within the gap between the lower cover plate 18 and the support 1.

[0046] See Figures 5-7 The diagram shows the structure of the upper protective paper tray 3. There is a limiting plate in the middle of the upper support plate 14.

The sliding pins on the upper ejector pins 16 are inserted into the arc-shaped grooves of the upper turntable 17. When the upper turntable 17 rotates, it can drive the upper ejector pins 16 to extend and retract. The upper ejector pins 16 can be inserted into the gaps between the stator wires and are located at the upper end of the insulating paper to provide protection for the upper insulating paper.

[0047] The upper turntable 117 is connected to the upper cylinder 22 via the upper connecting rod 20 and the upper connector 21. When the upper cylinder 22 is working, it can drive the upper turntable 17 to rotate within the gap between the upper cover plate 19 and the upper support plate 14.

[0048] See Figure 1 The support 1 and the upper support plate 14 are movably installed through the guide post 23 and the guide sleeve 24. Different height shims 25 are selected according to different height stator coils and are inserted between the support 1 and the upper support plate 14. There is also a slot at the lower end of the upper support plate 14 for inserting the shims 25, which facilitates positioning and installation.

[0049] See Figure 1 The translation cylinder 27, which is mounted on the support 1 via the translation cylinder frame 26, is fixedly connected to a slider on the guide rail 4. When the translation cylinder 27 is working, it can drive the transverse frame 5 to move back and forth, thereby driving the corresponding pressing cylinder 6 and the pressing block 7 to move into / out of the pressing position.
