Rotor assembly, solenoid valve, ir-cut switch and iris aperture

Abstract

The invention discloses a rotor component, an electromagnetic valve, an IR-CUT switcher and an IRIS aperture, and relates to the technical field of electromagnets, IR-CUT switchers and IRIS aperture driving devices. The rotor component comprises a crank, a shaft core and a permanent magnet, wherein the shaft core is fixed on the crank or passes through the crank and is fixedly connected with a device outside the rotor component; a block is arranged on the crank and is coaxial to the shaft core; the permanent magnet has an annular structure; two planes are arranged on the outer side wall of the permanent magnet and are relatively parallel; and when the permanent magnet is arranged on the crank in a sleeving manner, the plane on the side wall of the permanent magnet is in direct contact with the plane on the inner wall of the permanent magnet. According to the rotor component, a dispensing process between the permanent magnet and the crank can be reduced, fool-proofing spacing is carried out for the permanent magnet structurally, the magnetic poles of the permanent magnet are marked, and the rotation pulling force between the crank and the permanent magnet is large. The rotor component has the advantages of high stability, high uniformity, high accuracy, simple process, high efficiency, good operability and excellent automation.

Description

technical field [0001] The invention relates to the technical field of a solenoid valve, an IR-CUT switcher and an IRIS aperture driving device, in particular to a rotor assembly and a solenoid valve using the rotor assembly, an IR-CUT switcher and an IRIS aperture. Background technique [0002] In the prior art, whether it is a solenoid valve, an IR-CUT switch or an IRIS aperture, a rotor will be used. The rotor used in the above devices generally includes a crank handle, a shaft core and a permanent magnet. The shaft core is fixed on the crank handle or worn The crank handle is fixedly connected with components other than the rotor assembly, and the permanent magnet is sleeved on the rock handle. In the prior art, the rocker and the permanent magnet are fixedly connected through the bonding process, resulting in the following disadvantages: 1) The assembly process is complicated, the efficiency is low, the workability is poor, and the automation cost is high (difficult dis...

Problems solved by technology

In the prior art, the rocker and the permanent magnet are fixedly connected by bonding process, resulting in the following disadvantages: 1) The assembly process is complicated, the efficiency is low, the workability is poor, and the automation cost is high (difficult dispensing operation, efficiency low, easy to leave glue, more glue, less glue); 2) dispensing control pull-off force, poor control of glue volume, small pull-off force, low pull-off force stability, and poor consistency; 3) Assembly between permanent magnet and rocker Low precision, the N pole and S pole of the permanent magnet are on the circumference, which cannot be marked, and the assembly precision is low
