Description

Technical Field

[0001] This utility model relates to the field of electromagnet technology, specifically a bidirectional electromagnet. Background Technology

[0002] In numerous fields such as automation control, precision machinery, and medical devices, bidirectional electromagnets serve as core components for reciprocating motion control, and their performance directly impacts equipment operating efficiency and control accuracy. As industrial production demands increasing automation, more stringent requirements are being placed on bidirectional electromagnets' rapid commutation capabilities, structural simplification, and ease of operation.

[0003] In existing technologies, traditional bidirectional electromagnets often achieve bidirectional motion control through complex mechanical transmission structures or multiple independently controlled electromagnetic components. For example, some bidirectional electromagnets use two independent drive systems to control the left and right movements of the moving iron core separately. This structure not only makes the overall device bulky and increases the number of parts, but also increases assembly difficulty and manufacturing costs. Furthermore, because the two drive systems require precise coordinated control, response delays can easily occur during commutation, making it difficult to meet the demands of high-speed commutation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a bidirectional electromagnet that solves the problem that traditional bidirectional electromagnets often rely on complex mechanical transmission structures or multiple independently controlled electromagnetic components to achieve bidirectional motion control.

[0022] This utility model discloses a bidirectional electromagnet, which has the following beneficial effects:

[0023] This invention utilizes the cooperation between a bidirectional moving mechanism and a coil mechanism. Since two connecting rods are respectively connected to both ends of the moving iron core, the three components form a unified whole and move simultaneously.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] This application provides a bidirectional electromagnet that solves the problem that traditional bidirectional electromagnets often rely on complex mechanical transmission structures or multiple independently controlled electromagnetic components to achieve bidirectional motion control. It enables the moving iron core 21 to move to the left or right, with a simple structure, convenient operation, and the ability to quickly change direction.

[0031] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0032] This utility model provides, for example Figure 1-3 The bidirectional electromagnet shown includes: a mounting mechanism 1; a bidirectional moving mechanism 2, which is movably disposed inside the mounting mechanism 1; a coil mechanism 3, which is mounted on both sides of the inner cavity of the mounting mechanism 1, and the coil mechanism 3 and the bidirectional moving mechanism 2 are in a movable fit; and a terminal block 4, which is mounted on the mounting mechanism 1, and the terminal block 4 facilitates the selective power supply of the two electromagnetic coils 32.

[0033] The installation mechanism 1 includes: a protective shell 11, which is a cylindrical structure with openings at both ends; a fixed iron core 12, which is fixedly installed at the openings at both ends of the protective shell 11 and is movably fitted with the bidirectional moving mechanism 2; and a sleeve 13, which is fixedly installed in the middle of the inner cavity of the protective shell 11 and is used to limit the sliding of the bidirectional moving mechanism 2. The protective shell 11 facilitates the installation of the fixed iron core 12 and the terminal block 4. The end of the fixed iron core 12 is provided with a tapered groove to facilitate its interaction with the end of the moving iron core 21. The sleeve 13 facilitates the limiting of the linear sliding of the moving iron core 21, making the linear sliding of the moving iron core 21 more stable.

[0034] Specifically, the bidirectional moving mechanism 2 includes: a moving iron core 21, which is slidably disposed inside the sleeve 13; and connecting rods 22, which are fixedly installed at both ends of the moving iron core 21 and are movably engaged with the fixed iron core 12. Both ends of the moving iron core 21 are tapered, and the two connecting rods 22 are fixedly installed at both ends of the moving iron core 21, thereby allowing the moving iron core 21 and the two connecting rods 22 to move as a whole, facilitating bidirectional movement.

[0035] The coil mechanism 3 includes: a mounting cylinder 31, which is located inside the protective shell 11 and fixedly mounted on the fixed iron core 12; and an electromagnetic coil 32, which is wound around the mounting cylinder 31. The two electromagnetic coils 32 are connected in parallel through terminals 4. Since the two connecting rods 22 are respectively connected to the two ends of the moving iron core 21, the three components are integrated and move simultaneously. By selectively energizing one of the two electromagnetic coils 32, a magnetic field is generated by the electromagnetism principle, which attracts the moving iron core 21, thereby controlling the moving iron core 21 to move to the left or right. The structure is simple, the operation is convenient, and it can achieve rapid reversal. The control logic of this invention is simple and clear. Bidirectional motion control can be achieved simply by selectively energizing one of the two electromagnetic coils 32, without the need for complex circuit control modules. This not only simplifies the control process and reduces the technical requirements for operators, but also reduces potential failure points due to circuit complexity, improves the stability and reliability of the electromagnet's operation, and reduces maintenance costs.
