Description

Technical Field

[0001] The utility model relates to the technical field of chain motors, and particularly relates to a stator core of a chain motor. Background Art

[0002] A chain motor usually refers to a chain-type electric motor, which is a motor that converts electrical energy into mechanical energy. Its basic working principle is electromagnetic induction. When an electric current passes through a coil, a magnetic field will be generated. This magnetic field interacts with the magnetic field of a permanent magnet or an electromagnet in the motor to generate a torque, thereby driving the rotation of the motor rotor.

[0003] The stator of a motor is an important part of the motor. It works together with the motor rotor to jointly complete the conversion between electrical energy and mechanical energy. The stator is usually fixed inside the motor housing and does not rotate with the rotor. In an AC motor, the stator includes windings that generate a rotating magnetic field. These windings are usually wound around an iron core to form stator coils. However, since the iron core of the stator is often integrally produced, when the stator core is damaged and the iron core sheets need to be disassembled, it is often necessary to remove the coil windings, which is very inconvenient.

[0004] In view of this, a stator core of a chain motor is proposed. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problem that the coil windings need to be disassembled when repairing or disassembling the stator core, and to provide a stator core of a chain motor.

[0006] To solve the above technical problems, the utility model adopts the following technical scheme: A stator core of a chain motor includes a mounting base, on which a plurality of mutually spliced mounting blocks are arranged. An installation groove is provided on the mounting block, and a plurality of installation bars are slidably arranged in the installation groove. Iron core sheets are fixedly connected to the plurality of installation bars. A first limiting frame for limiting the spliced mounting blocks and a second limiting frame for limiting the iron core sheets after installation are arranged on the mounting base. A plurality of elastic telescopic rods are fixedly connected to the mounting base, and two locking blocks for locking the first limiting frame and the second limiting frame respectively are fixedly connected to the elastic telescopic rods.

[0007] Further, a plug block arranged in a T shape is fixedly connected to the mounting block, and a slot adapted to the size of the plug block is provided on the mounting block. The plug block is used to insert the mounting block into the slot of another mounting block to complete the connection of adjacent mounting blocks.

[0008] Further, a limiting bar for limiting the mounting block is slidably arranged in the installation groove. A sliding bar is fixedly connected to the limiting bar, and a sliding groove adapted to the size of the sliding bar is provided in the installation groove. The sliding bar is used to extract the iron core sheet after its disassembly.

[0009] Further, the elastic telescopic rod includes a main rod provided with a hollow interior and a sub-rod inserted into the main rod. The bottom of the sub-rod and the inner bottom wall surface of the main rod are elastically connected by a spring.

[0010] Further, a first channel for the locking block to pass through is formed on the first limiting frame, a second channel for the locking block to pass through is formed on the second limiting frame, locking grooves for limiting the locking block are arranged at both the first channel and the second channel, and the locking grooves are used to limit the first limiting frame and the second limiting frame so as to fix the mounting block and the iron core chip.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] For the stator core of the chain motor provided by the utility model, through the arrangement of the limiting strip, when the iron core chip needs to be disassembled during the subsequent use of the device, the limiting strip can be directly pulled out, and then the iron core chip can be pulled out from the coil winding, solving the problem that the coil winding needs to be removed during the repair or disassembly of the traditional stator core;

[0013] For the stator core of the chain motor provided by the utility model, through the assembled setting of the mounting block, the repair or disassembly of the stator core is very convenient, solving the problem that the integrated setting of the traditional stator core is inconvenient for repair or disassembly;

[0014] For the stator core of the chain motor provided by the utility model, through the arrangement of the locking block and the locking groove, it is very convenient to release the limitation of the first limiting frame and the second limiting frame on the mounting block and the iron core chip.

Detailed implementation manners

[0026] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figure 1-8 .

[0028] The stator core of the chain motor of the present utility model includes a mounting base 1, a plurality of mutually spliced mounting blocks 2 are arranged on the mounting base 1, a mounting groove 23 is opened on the mounting block 2, a plurality of mounting strips 61 are slidably arranged in the mounting groove 23, iron chips 6 are fixedly connected to the plurality of mounting strips 61, a first limit frame 3 for limiting the spliced mounting blocks 2 and a second limit frame 4 for limiting the iron chips 6 after installation are arranged on the mounting base 1, a plurality of elastic telescopic rods 5 are fixedly connected to the mounting base 1, and two locking blocks 54 for locking the first limit frame 3 and the second limit frame 4 respectively are fixedly connected to the elastic telescopic rods 5.

[0029] In addition, an insert block 22 arranged in a T shape is fixedly connected to the mounting block 2, a slot 21 adapted to the size of the insert block 22 is opened on the mounting block 2, and the insert block 22 is used to insert the mounting block 2 into the slot 21 of another mounting block 2 to complete the connection of adjacent mounting blocks 2.

[0030] As Figure 1 or Figure 2 shown, after the mounting blocks 2 are spliced together, the inner wall surfaces of the mounting blocks 2 together form a circle, and this circle should exactly fit the mounting seat 1. In this embodiment, there are 18 mounting blocks 2, and each mounting block 2 is provided with 25 iron chips 6.

[0031] In addition, a limiting strip 231 for limiting the mounting block 2 is slidably arranged in the mounting groove 23. A sliding strip 2311 is fixedly connected to the limiting strip 231. A sliding groove 2312 adapted to the sliding strip 2311 is formed in the mounting groove 23. The sliding strip 2311 is used to draw out the iron chip 6 after its disassembly, as Figure 3 or Figure 4 shown. The sliding strip 2311 is a long strip with an L-shaped cross section, and its length is the same as that of the limiting strip 231. When both limiting strips 231 of a mounting groove 23 are removed, the mounting groove 23 can no longer limit the mounting strip 61. That is to say, the two limiting strips 231 and the mounting groove 23 together form a T-shaped channel to complete the fixation of the mounting strip 61 and the iron chip 6.

[0032] Secondly, as Figure 8 shown, the elastic telescopic rod 5 includes a hollow main rod 51 and a sub-rod 52 inserted into the main rod 51. The bottom of the sub-rod 52 and the inner bottom wall surface of the main rod 51 are elastically connected by a spring 53. Moreover, a first channel 31 for the locking block 54 to pass through is formed in the first limiting frame 3, and a second channel 41 for the locking block 54 to pass through is formed in the second limiting frame 4. Locking grooves 42 for limiting the locking block 54 are arranged at both the first channel 31 and the second channel 41. The locking grooves 42 are used to limit the first limiting frame 3 and the second limiting frame 4 to fix the mounting block 2 and the iron chip 6.

[0033] It should be noted that during specific setting, after the first limiting frame 3 and the second limiting frame 4 are installed, the locking block 54 is rotated so that the locking block 54 can just pass through the first channel 31 and the second channel 41, and then the locking block 54 is rotated so that the locking block 54 can just be limited by the locking groove 42, so as to complete the fixation of the first limiting frame 3 and the second limiting frame 4. When disassembling the iron chip 6, it is necessary to first pull out the sub-rod 52 and rotate the sub-rod 52 so that the locking block 54 can just pass through the first channel 31 and the second channel 41 to complete the disassembly of the first limiting frame 3 and the second limiting frame 4, and then the limiting strip 231 can be pulled out. At this time, the mounting groove 23 no longer limits the mounting block 2, and the iron chip 6 can be directly pulled out.

[0034] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model.
