Description

Technical Field

[0001] The utility model relates to the technical field of linear motor iron cores, and more particularly to an assemblable linear motor iron core. Background Art

[0002] With the rapid development of industries such as industrial automation, precision machining, and semiconductor manufacturing, the demand for high-precision, high-speed, and high-responsive linear motion equipment is increasing. Linear motors have emerged as the times require, and their performance depends largely on the internal structural design of the motor. The iron core is a key component, which is usually a metal part with a certain shape and structure. However, existing linear motor iron cores still have some problems in practical application, such as:

[0003] First, in actual production, linear motor cores are produced by one-piece stamping. Extending the product requires additional molds, production processes, and handling processes, which increases inventory types. Furthermore, the copper wire inserted into the core during production is easily scratched.

[0004] Second, if Figure 7 As shown, conventionally produced linear motor cores are all one-piece, and the length of conventional linear motor cores is adjusted in multiples of three. A new mold must be developed for each additional linear motor core of a different length, which results in a considerable investment in mold costs and machine equipment. At the same time, when the linear motor core with an one-piece structure is too long, due to its large size, it is often deformed during transportation due to excessive weight.

[0005] In view of the above problems, the present invention provides an assemblable linear motor core. Utility Model Content

[0008] A further preferred solution is that the cross section of the first sliding block is a trapezoidal structure.

[0009] A further preferred solution is that the cross section of the second slider is a dovetail structure.

[0010] A further preferred solution: the main iron core and the sub-iron core are both plate-shaped structures.

[0011] A further preferred solution is that a plurality of grooves are provided through one end of the main core away from the first chute.

[0024] The following is a combination of the appended examples of the present invention Figures 1-6 , clearly and completely describe the technical solutions in the embodiments of the present utility model.

[0025] See also Figure 1-6 In an embodiment of the present invention, an assemblable linear motor core includes a linear motor core body, which is composed of a main core 1 and multiple sub-cores 2. The first end of the main core 1 is integrally formed with a second slider 4, and the second end of the main core 1 is provided with a second slide groove 3. The main core 1 between two adjacent linear motor core bodies can be clamped by the second slider 4 and the second slide groove 3. The sub-core 2 is fixedly connected with a first slider 21, and the main core 1 is provided with a first slide groove 6 for the first slider 21 to be clamped. The three sub-cores 2 are arranged along the length direction of the main core 1.

[0026] Specifically, when assembling the linear motor core, first connect the sub-core 2 to the main core 1 through a buckle, and install three sub-cores 2 on each main core 1. The installation of the two can be achieved by snapping the first slider 21 of the sub-core 2 with the first slide 6 to realize the installation of the linear motor core body. Then, according to the required length of the linear motor core, the main cores 1 on multiple linear motor core bodies are connected in sequence by snapping the second slider 4 with the second slide 3. In the process of connecting adjacent main cores 1, pay attention to accurately match the second slider 4 with the corresponding second slide 3 to ensure a firm connection, so that the sub-core 2 on each main core 1 Located in the same direction, the overall installation steps are simple. It only needs to open the mold once according to the shape of the linear motor core body, and then it can be extended in combination as needed, reducing the investment in molds and production costs. At the same time, it avoids the problem of additional investment in molds, production processes and transportation processes due to product extension, avoiding the increase in inventory types and the phenomenon that the copper wire is easily scratched when it is placed in the core during production. Secondly, since the linear motor core can be realized by connecting multiple linear motor core bodies according to the required length, this makes the transportation process of the linear motor core before assembly more convenient, reduces the transportation volume, and improves convenience.

[0027] It should be noted that the linear motor core body can be used in existing production line handling, packaging and arranging, automatic laser welding machines, conveyor belts, linear guides, micro water grinders and other fields. It can replace the traditional conveyor belts and linear guides of linear assembly lines, and can be assembled on site to the required length. Compared with the traditional integrated linear motor core, it is faster and more accurately positioned; secondly, since the traditional linear motor core is an one-piece molded structure, it is necessary to manually coat the sub-core 2 during the production process. Because the length of the main core 1 varies, there is no way to use automated mechanical equipment. When coating the linear motor core in this example, each linear motor core body can be split, and the linear motor core body can be split into the main core 1 and the sub-core 2. Since the sub-core 2 has the same shape and structure, the split sub-core 2 can be batch coated with glue using automated equipment, eliminating the manual coating process.

[0028] In the embodiment of the present utility model, Figures 1 to 5 As shown, the cross-section of the first slider 21 is a trapezoidal structure. Specifically, along the extension direction of the first slide groove 6, the cross-section of the first slider 21 is a trapezoidal structure. The first slider 21 with a trapezoidal structure can ensure that the sub-core 2 is accurately positioned in the direction perpendicular to the slide groove when installed on the main core 1. Compared with other simple shapes such as a rectangle, the hypotenuse of the trapezoid can form a more accurate fit with the slide groove wall, reduce installation deviation, and ensure the position accuracy of the sub-core 2 on the main core 1, thereby improving the consistency of the electromagnetic performance of the entire core. During the operation of the motor, due to factors such as vibration, the first slider 21 with a trapezoidal structure can generate a certain self-locking force in the slide groove; it should be noted that, in this embodiment, the shape of the first slider 21 can be adjusted according to actual conditions, and there is no limitation here.

[0029] In the embodiment of the present utility model, Figures 1 to 4 As shown, the cross-section of the second slider 4 is a dovetail structure. Specifically, along the extension direction of the second slide groove 3, the cross-section of the second slider 4 is a dovetail structure. For the second slider 4, the dovetail structure can withstand greater tension and shear force after clamping than other shapes. During the operation of the linear motor, especially under high load or high acceleration conditions, this structure can ensure that the main iron core 1 between adjacent linear motor core bodies is firmly connected without loosening or detachment, thereby maintaining the normal operation of the motor. Secondly, the dovetail structure itself has a certain guiding property. When assembling the main iron core 1 of adjacent linear motor core bodies, it can more accurately guide the second slider 4 into the second slide groove 3, which helps to improve assembly efficiency and quality and reduce assembly errors caused by improper clamping. Furthermore, in this embodiment, the shape of the second slider 4 can be adjusted according to actual conditions and is not limited here.

[0030] In the embodiment of the present utility model, Figures 1 to 6 As shown, both the main core 1 and the sub-core 2 are plate-shaped structures. Specifically, this makes the cores easier to manufacture, assemble, and install in linear motors. Plate-shaped structures are relatively easy to process and can be manufactured using conventional methods such as stamping and cutting. Compared to complex three-dimensional cores, the processing technology for plate-shaped cores is more mature, resulting in lower costs and higher production efficiency.

[0031] In the embodiment of the present utility model, Figure 2 and Figure 3 As shown, a plurality of grooves 5 are provided through the end of the main core 1 away from the first slide groove 6, and the plurality of grooves 5 are arranged at equal intervals. Specifically, the design of the grooves 5 can reduce the weight of the core without affecting the main function of the core.

[0032] Working principle: When assembling the linear motor core, first connect the sub-core 2 to the main core 1 through a buckle. Each main core 1 is installed with three sub-cores 2. The installation of the two can be achieved by snapping the first slider 21 of the sub-core 2 with the first slide 6 to realize the installation of the linear motor core body. Then, according to the required length of the linear motor core, the main cores 1 on multiple linear motor core bodies are connected in sequence by snapping the second slider 4 with the second slide 3. In the process of connecting adjacent main cores 1, pay attention to accurately match the second slider 4 with the corresponding second slide 3 to ensure a firm connection, so that the sub-core 2 on each main core 1 Located in the same direction, the overall installation steps are simple. It only needs to open the mold once according to the shape of the linear motor core body, and then it can be extended in combination as needed, reducing the investment in molds and production costs. At the same time, it avoids the problem of additional investment in molds, production processes and transportation processes due to product extension, avoiding the increase in inventory types and the phenomenon that the copper wire is easily scratched when placed in the core during production. Secondly, since the linear motor core can be connected to multiple linear motor core bodies according to the required length, this makes the transportation process of the linear motor core body before assembly more convenient, reduces the transportation volume, and improves convenience.
