Description

Technical Field

[0001] The utility model relates to the technical field of solenoid valve production, in particular to a wire winding device for solenoid valve production. Background Technique

[0002] A solenoid valve is a device that uses the action of electromagnetic force to control the flow of liquid or gas. It mainly consists of components such as an electromagnetic coil, a valve core, a valve seat, and a spring. When the electromagnetic coil is energized, a magnetic field is generated, causing the valve core to move under the action of electromagnetic force, thereby changing the opening and closing state of the valve. During the production process of the electromagnetic coil, a wire winding device is required to wind copper wire around the wire winding cylinder of the electromagnetic coil to form the electromagnetic coil. When using the wire winding device, it is necessary to first position the wire winding cylinder and then wind the copper wire around the wire winding cylinder to achieve wire winding during the production process of the electromagnetic coil.

[0032] As Figures 1 - 5As shown in the figure, an embodiment of the utility model provides a wire winding device for solenoid valve production, including a base 1, on which a vertical plate is fixed. On one side of the vertical plate, a servo motor 3 is fixed. On the other side of the vertical plate, a moving mechanism is arranged. The moving mechanism mainly consists of a motor, a screw rod, an internally threaded block and a guide rail. The motor is fixed on the front side of the vertical plate, the guide rail is fixed on the rear side of the vertical plate, the screw rod is rotatably connected in the guide rail, the internally threaded block is threadedly connected to the screw rod, and when the motor drives the screw rod to rotate, the internally threaded block moves along the inner wall of the guide rail. A connecting plate is fixed on the side surface of the internally threaded block. A storage box is arranged on the side surface of the moving mechanism and is fixed on the connecting plate. When the internally threaded block moves, the storage box can be driven to move back and forth through the connecting plate. Copper wire is stored in the storage box, and a rotating shaft is installed in the storage box. The copper wire is wound around the rotating shaft. When the storage box moves back and forth, the position of the copper wire wound around the winding cylinder 4 is changed. It further includes:

[0033] A positioning shaft 5, which is fixed at the output end of the servo motor 3. The winding cylinder 4 is sleeved on the positioning shaft 5. A connecting block 14 is fixed on the positioning shaft 5. The side surface of the connecting block 14 is fixedly connected to the inner wall of the central sleeve 8. The connecting block 14 is used for connecting and fixing the central sleeve 8 and the positioning shaft 5. Rubber rings 7 are fixed at both ends of the central sleeve 8. On one side of the two rubber rings 7 away from the central sleeve 8, a circular ring 6 and a guiding block 9 are respectively fixed. The circular ring 6 is fixedly sleeved on the positioning shaft 5. The circular ring 6 is used for closing the front side direction of the front rubber ring 7. The guiding block 9 is fixed at one end of the positioning shaft 5 away from the servo motor 3. The guiding block 9 is used for closing the rear side direction of the rear rubber ring 7;

[0034] Intake ring 11 is sleeved on the positioning shaft 5. A gas pump 2 is fixed at the bottom of the base 1. The power supply mode of the gas pump 2 is an external power source. A trachea is fixed at the air outlet of the gas pump 2. A rigid tube 19 penetrates through and is fixed at the top of the base 1. One end of the rigid tube 19 is fixedly connected to the end of the trachea. The intake ring 11 is fixed at the other end of the rigid tube 19. The rigid tube 19 is used for fixing the intake ring 11. The gas pump 2 supplies gas into the intake ring 11 through the trachea and the rigid tube 19. An annular groove 12 is formed on the circumferential surface of the positioning shaft 5. Two sealing rings are inlaid on the inner wall of the intake ring 11. The two sealing rings are respectively located on both sides of the annular groove 12. The sealing rings are used for sealing between the intake ring 11 and the positioning shaft 5 to prevent air flow from leaking out through the gap between the intake ring 11 and the positioning shaft 5. A cavity 10 is arranged inside the positioning shaft 5. A plurality of air intake holes are formed on the inner wall of the annular groove 12. The air intake holes are used for communicating the cavity 10 with the annular groove 12. A plurality of air outlet holes 13 are formed on the circumferential surface of the positioning shaft 5 corresponding to the position of the connecting block 14. The air outlet holes 13 are communicated with the cavity 10. A diversion groove 15 is formed on the connecting block 14 corresponding to the position of the air outlet holes 13. After the gas pump 2 operates, the air flow enters the rubber ring 7, causing the rubber ring 7 to expand and fit against the inner wall of the winding drum 4. Anti-slip lines are formed on the circumferential surface of the rubber ring 7. The anti-slip lines are used to increase the friction between the rubber ring 7 and the inner wall of the winding drum 4, enhancing the connection tightness between the expanded rubber ring 7 and the winding drum 4, thereby improving the fixing stability of the winding drum 4.

[0035] As Figure 2 shown, in this embodiment, the side of the guiding block 9 away from the positioning shaft 5 is hemispherical. The hemispherical shape is used to guide the winding drum 4 when it is sleeved on the positioning shaft 5, thus facilitating the sleeving of the winding drum 4 on the positioning shaft 5.

[0036] As Figure 2 shown, in this embodiment, a positioning disk 18 is fixedly sleeved on the positioning shaft 5. The side surface of the positioning disk 18 is in contact with the side surface of the winding drum 4. When the winding drum 4 is sleeved on the positioning shaft 5 and in contact with the positioning disk 18, the initial positioning of the winding drum 4 in the axial direction of the positioning shaft 5 is achieved through the positioning disk 18.

[0037] As Figure 2 shown, in this embodiment, the inner wall of the annular groove 12 is a curved surface that bends towards the inside of the positioning shaft 5. The curved surface is used to guide the air flow when flowing from the intake ring 11 into the cavity 10, making the air flow more smooth.

[0038] As Figure 2As shown in the figure, in this embodiment, a first flow guide block 16 is fixed on the inner wall of the cavity 10 near the servo motor 3. The side surface of the first flow guide block 16 is a first inclined surface, and the inclination angle of the first inclined surface is 45 degrees. After the air flow enters the cavity 10 from the air inlet hole, it is smoothly guided by the first inclined surface on the first flow guide block 16 and flows towards the air outlet hole 13. The cooperation of the first flow guide block 16 and the first inclined surface makes the air flow more smooth.

[0039] As Figure 2 shown in the figure, in this embodiment, a second flow guide block 17 is fixed on the inner wall of the cavity 10 away from the servo motor 3. The second flow guide block 17 is conical. After the air flow flows to the position of the second flow guide block 17, it is automatically guided by the conical second flow guide block 17 and flows towards the air outlet hole 13. The second flow guide block 17 improves the smoothness of the air flow.

[0040] As Figure 3 shown in the figure, in this embodiment, a second inclined surface is provided on the inner wall of the air outlet hole 13. The second inclined surface is used to increase the flow velocity of the air flow flowing through the air outlet hole 13, increase the air flow passing amount from the air outlet hole 13 at the same time, and thus improve the expansion speed of the rubber ring 7.

[0041] As Figure 5 shown in the figure, in this embodiment, a V-shaped flow guide surface is provided on the inner wall of the flow guide groove 15. The flow guide surface is used to guide the air flow passing through the flow guide groove 15, so that the air flow smoothly flows towards both sides of the connecting block 14, realizing the diversion of the air flow.

[0042] Working principle: The winding drum 4 is sleeved on the positioning shaft 5, and the side surface of the winding drum 4 is attached to the side surface of the positioning disk 18. Then, the air pump 2 is started to make the air flow enter the intake ring 11 through the rigid tube 19. Then, the air flow enters the cavity 10 through the air inlet holes in the annular groove 12. After the air flow enters the cavity 10 from the air inlet holes, it flows towards the second flow guide block 17 along the guidance of the first flow guide block 16. The air flow flowing to the position of the second flow guide block 17 is smoothly guided by the second flow guide block 17 and flows towards the air outlet hole 13. When the air flow flows out from the air outlet hole 13, it automatically flows towards both sides of the connecting block 14 along the guidance of the flow guide groove 15, so that the air flow enters the two rubber rings 7, making the rubber rings 7 expand outwards and closely fit with the inner wall of the winding drum 4, realizing the fixation of the winding drum 4. After fixation, after connecting the end of the copper wire in the storage box to the winding drum 4, the servo motor 3 is started. The output shaft of the servo motor 3 drives the positioning shaft 5 to rotate, the positioning shaft 5 drives the winding drum 4 to rotate, and during the rotation of the winding drum 4, the moving mechanism drives the storage box to move back and forth. The winding of the copper wire on the winding drum 4 is realized by the combination of the forward and backward movement of the storage box and the rotation of the winding drum 4, thus completing the production and processing of the electromagnetic coil.

[0043] The present utility model covers any alternatives, modifications, equivalent methods and solutions made on the essence and scope of the present utility model. In order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the above preferred embodiments of the present utility model, and those skilled in the art can fully understand the present utility model without the description of these details.

[0044] The above are only the preferred embodiments of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
