Description

Technical Field

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

[0002] There is a sealed cavity in the solenoid valve, with through holes opened at different positions. Each hole is connected to a different oil pipe. In the middle of the cavity is a piston, and on both sides are two electromagnets. Whichever side's magnet coil is energized, the valve body will be attracted to that side. By controlling the movement of the valve body, different oil discharge holes can be opened or closed. The magnet coil is a relatively important component in the solenoid valve, which includes a coil cylinder and a wire wound around its surface. When winding the magnet coil, a wire winding device is required. For example, in the patent (CN215528830U3), a wire winding device for a motor coil, through the provided wire cylinder and limiting structure, when the wire on the surface of the wire cylinder is not fully used, the wire can be fixed by the limiting structure, avoiding the loss of tension at one end of the wire and thus preventing it from loosening and falling off, which may affect subsequent operations. It can assist in fixing the wire while not affecting the winding, reducing unnecessary troubles. However, during the wire winding process of the solenoid valve coil, the wire rubs against the limiting plate, and the generated high temperature is likely to damage the external insulation layer of the wire, resulting in coil leakage. Content of the Utility Model

A motor is installed on the base, and the power shaft of the motor is connected to the rotating shaft of the second winding roller. Winding cylinders are sleeved on both the first winding roller and the second winding roller, and a wire is wound around the winding cylinders. A fixed frame is fixed on the base, and a linear slide rail is fixedly installed on the fixed frame. A wire clamping device is slidably arranged on the linear slide rail, and the wire passes through the wire clamping device and is in rolling connection.

[0006] Preferably, a threaded hole is opened at the end of the rotating shaft, and a butting cylinder is threadedly connected to the end of the rotating shaft. A screw rod is coaxially arranged in the inner cavity of the butting cylinder, and the end of the butting cylinder abuts against the winding cylinder.

[0007] Preferably, a clamping groove is opened on the outer wall of the power shaft of the motor.

[0008] Preferably, the wire clamping device includes a fixed seat, and linear bearings are fixedly connected to both sides of the fixed seat. The linear slide rail passes through the linear bearings.
