Abstract
Description
Technical Field
[0001] This utility model relates to the field of electromagnet technology, specifically a novel electromagnet structure. Background Technology
[0002] Solenoid valves are a major branch of actuators in automated instrumentation. They are electromagnetic components that convert electromagnetic energy into mechanical energy. These valves are automatic control valves that are operated by command signals to energize or de-energize an electromagnetic coil, using electromagnetic attraction to complete opening and closing actions. Due to their advantages such as small size, sensitive action, reliable performance, and ease of computer connection, they are widely used in various industries and daily life facilities. The electromagnet is the key to the reliable operation of the entire solenoid valve. The electromagnet mainly relies on the electromagnetic force generated in the electromagnetic system to make the armature move mechanically, overcoming the resistance of the mechanical load to do work. Therefore, the design structure of the electromagnet is crucial. In existing technology, electromagnets can convert input electrical signals into force and displacement. When energized, the on / off electromagnet attracts the armature from one extreme position to another. After de-energization, it quickly returns to the initial extreme position under the action of spring force. However, ensuring the dimensional accuracy of the armature during actual processing is currently a major hurdle. Ensuring the straightness of axial movement requires controlling the gap between the spacer and the armature. If it is too large, it will affect the attraction force; if it is too small, it will cause the armature to work inflexibly, leading to the solenoid valve malfunctioning. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-2 This embodiment provides a technical solution: a novel electromagnet structure, including a welding assembly 9. The welding assembly 9 includes a welding shell for easy welding to external components. An armature 6 is slidably connected inside the welding assembly 9. An actuating shaft 11 is located in the middle of the armature 6, and a shoe stop 3 is located at the left end of the actuating shaft 11. The shoe stop 3 is used to enhance the magnetic field strength, adjust the sensitivity, and expand the measurement range. A coil assembly 10 is located inside the welding assembly 9. The coil assembly 10 includes a coil, which is disposed inside the welding assembly 9. The armature 6 is located inside the coil. When the coil is energized, the armature 6 moves under the action of the magnetic field. The left end of the actuator 11 is threaded with a screw plug 1, which restricts the position of the shoe stop 3 on the actuator 11. The outer arc surface of the screw plug 1 is provided with an O-ring 2, which fits against the left side of the shoe stop 3 to seal between the screw plug 1 and the shoe stop 3. The outer arc surface of the shoe stop 3 is provided with an O-ring 5, which fits against the inner wall of the welding assembly 9 to seal between the shoe stop 3 and the welding assembly 9. The welding assembly 9 is laterally slidably connected with a limiting piece 7, which blocks the armature 6 and restricts the movement range of the armature 6. The feature is that it also includes a bushing 4 and a bushing 8.
[0020] Bushing 4: It is set in the groove of the inner arc surface of the shoe stop 3. Bushing 4 is movably sleeved on the left end of the outer arc surface of the actuator shaft 11, providing guide support for the left end of the actuator shaft 11.
[0021] Bushing 2 8: It is located in the mounting groove in the middle of the welding assembly 9. Bushing 2 8 is movably sleeved on the right end of the outer arc surface of the actuator shaft 11, providing guide support for the right end of the actuator shaft 11. Both bushing 1 4 and bushing 2 8 have sliding grooves 12 on their inner arc surfaces. Limiting slip rings 13 are laterally slidably connected inside the sliding grooves 12. Connecting slip rings 14 are provided on the inner arc surface of the limiting slip rings 13. The connecting slip rings 14 are fixedly sleeved on the outer arc surface of the actuator shaft 11. During the movement of the actuator shaft 11, the limiting slip rings 13 are within the sliding grooves 12. The sliding mechanism provides guiding support for the movement of the actuator shaft 11 and the armature 6, reducing the axial positioning distance of the armature 6. The inner arc surface of the connecting slip ring 14 is provided with rubber pads 15 to fill the gap between the connecting slip ring 14 and the outer arc surface of the actuator shaft 11. Both the limiting slip ring 13 and the connecting slip ring 14 are ceramic slip rings, which makes their surface finish better than that of machined parts, reducing the jamming phenomenon that occurs when the armature 6 moves. The inner arc surface of the rubber pads 15 is a conical arc surface, which facilitates the insertion of the actuator shaft 11 into the rubber pads 15.
[0022] The working principle of the novel electromagnet structure provided by this utility model is as follows: When the electromagnet is energized and receives a signal, the armature 6 will move. During the movement of the armature 6 and the actuator shaft 11, the friction between the connecting slip ring 14 and the actuator shaft 11 is increased by the filling of the rubber pad 15, which causes the actuator shaft 11 to move the connecting slip ring 14 and the limiting slip ring 13 to slide in the slide groove 12. This provides guiding support for the movement of the actuator shaft 11 and the armature 6, and reduces the axial positioning distance of the armature 6. Moreover, both the connecting slip ring 14 and the limiting slip ring 13 are ceramic slip rings, and their surface finish is better than that of machined parts, which can reduce the jamming phenomenon that occurs when the armature 6 moves.
[0023] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
