Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, and in particular to a stator core using two shapes of silicon steel sheets stacked together. Background Technology

[0002] The stator core is a component in motors, generators and other similar electromagnetic devices. It is made of multiple silicon steel sheets stamped and stacked. This stacking structure is designed to reduce eddy current losses caused by alternating magnetic fields during operation and to provide an effective magnetic circuit path for the stator windings.

[0003] In existing production practices, the stacking height of stator cores is usually preset according to the specific power and performance indicators of the motor. This means that once the design is finalized, the thickness of the core is fixed. When it is necessary to produce motors of different specifications or power levels, it is often necessary to redesign and manufacture stator cores with different stacking heights. This not only increases mold costs and production preparation time, but also reduces the versatility of parts and the flexibility of the production line.

[0004] Furthermore, after the traditional stator core is assembled, the mounting structure used for fixing, such as the position of mounting holes or mounting lugs, is also fixed. This fixed installation method requires that the mounting interface of the motor housing or other supporting equipment must be precisely matched. Once the installation dimensions of the external equipment change, or when the same core needs to be applied to multiple different products, installation difficulties or even failure to install will occur, thus limiting the applicability of the stator core and reducing its installation adaptability in different application scenarios.

[0005] In summary, existing stator core technologies generally suffer from drawbacks in structural design, such as fixed stacking height and inflexible installation positions, making it difficult to meet the requirements of modern production for high efficiency, high versatility, and strong adaptability. Therefore, this utility model proposes a stator core using two shapes of silicon steel sheets stacked together to address the shortcomings of existing technologies. Utility Model Content

[0006] In view of the problems in the existing technology, such as the fixed stacking height of the stator core leading to poor versatility and the fixed installation position leading to insufficient installation adaptability, this utility model aims to provide a stator core with an improved structure that can effectively solve the above problems by using silicon steel sheets of two shapes stacked together.

[0007] This utility model provides a stator core using two shapes of silicon steel sheets stacked together, including: a bottom stator, a silicon steel sheet, a connecting mechanism, and an installation mechanism;

[0008] The connecting mechanism includes a connecting column one and a connecting column two that can be connected in sections, and the mounting mechanism includes an arc plate, a sliding block that can move in the sliding groove of the arc plate, a mounting ring connected to the sliding block, and an adjusting bolt for locking the sliding block.

[0009] Furthermore, the connecting mechanism is located at the top of the bottom stator. The silicon steel sheet is fixed in place by the first connecting post and the second connecting post, which can be detachably connected to the first connecting post to extend its length. The mounting mechanism is located at the bottom of the bottom stator. The installation position of the mounting ring is adjusted by adjusting the position of the sliding block in the sliding groove and locking the adjusting bolt.

[0010] Preferably, the top of the first connecting post is provided with a connecting groove, and the bottom of the second connecting post is inserted into the connecting groove by screwing.

[0011] Preferably, the silicon steel sheet one has fixing blocks on both sides, and the bottom of the fixing blocks has a circular groove for fitting onto the outer wall of the connecting column one or the connecting column two.

[0012] Preferably, the connecting mechanism further includes a top cover, which is threadedly connected to the topmost connecting post 2 for pressing the stacked silicon steel sheets 1.

[0013] Preferably, the top of the silicon steel sheet is provided with a positioning block, and the bottom is provided with a positioning groove adapted to the positioning block for alignment between the stacked silicon steel sheets.

[0014] Preferably, there are two arc-shaped plates, which are symmetrically fixed at the bottom of the bottom stator.

[0015] Preferably, the arc-shaped plate has multiple adjustment holes, and the adjustment bolt passes through the selected adjustment hole and engages with the sliding block through a thread to lock the sliding block.

[0016] Preferably, the mounting ring spans and connects the two sliding blocks.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model solves the problems of fixed stator core stacking height, single specifications, and poor versatility in the prior art by setting a connecting column that can be extended in sections and allowing silicon steel sheets to be stacked on the connecting column through the circular groove on it.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] Example:

[0028] Please refer to Figures 1 to 4This utility model embodiment provides a stator core using two types of silicon steel sheets stacked together, including a bottom stator 1 and silicon steel sheets 203 stacked on top of the bottom stator 1. The bottom stator 1 serves as the basic support platform for the entire stator core, and the silicon steel sheets 203 form the magnetic conductive body of the stator core. The stator core using two types of silicon steel sheets stacked together also includes a connecting mechanism 2 for stacking and fixing the silicon steel sheets 203 onto the bottom stator 1, and an installation mechanism 3 for installing and fixing the entire stator core. The connecting mechanism 2 and the installation mechanism 3 work together to allow the overall structure of the stator core to not only flexibly adjust the stacking height but also conveniently adjust the installation position. Specifically, the connecting mechanism 2 includes a fixing mechanism... The bottom stator 1 has a connecting post 201 at the top and a connecting post 206 that can be detachably connected to the connecting post 201 to extend its length. The silicon steel sheet 203 is installed on the connecting post 201 or the connecting post 206 by sleeve. The mounting mechanism 3 includes an arc plate 301 fixed to the bottom of the bottom stator 1. The arc plate 301 has a sliding groove 302. The mounting mechanism 3 also includes a sliding block 303 that can slide in the sliding groove 302 and a mounting ring 304 connected to the sliding block 303. An adjusting bolt 306 is provided to position and lock the sliding block 303 in the sliding groove 302. The connecting mechanism 2 realizes the stacking function with adjustable height, and the mounting mechanism 3 realizes the installation function with adjustable position.

[0029] Please refer to Figure 2 and Figure 3 In the connecting mechanism 2, the bottom of the connecting post 1 201 is fixedly connected to the top of the bottom stator 1. A connecting groove 202 is provided on the top of the connecting post 1 201 to extend the connection height. The bottom of the connecting post 206 is inserted into the connecting groove 202 by screwing in, thus fixing it to the connecting post 1 201. Fixing blocks 204 are fixedly connected to the left and right sides of the silicon steel sheet 1 203. A circular groove 205 is provided at the bottom of the fixing block 204. During assembly, the circular groove 205 is fitted onto the outer wall of the connecting post 1 201 or the connecting post 206 to ensure the stacking of multiple silicon steel sheets 1 203. To ensure accurate alignment and prevent tilting, a positioning block 208 is fixed to the top surface of each silicon steel sheet 203. At the same time, a positioning groove 209 adapted to the shape and size of the positioning block 208 is opened on the bottom surface of the silicon steel sheet 203, so that the positioning groove 209 of the upper silicon steel sheet 203 and the positioning block 208 of the lower silicon steel sheet 203 can be inserted and engaged with each other. After all the silicon steel sheets 203 are stacked, the connecting mechanism 2 also includes a top cover 207. The top cover 207 is threaded to the top of the connecting post 206 at the top and presses all the stacked silicon steel sheets 203 together.

[0030] In a preferred embodiment, to clarify the structure of silicon steel sheet 203, fixing blocks 204 are fixedly connected to both sides of silicon steel sheet 203. A circular groove 205 is provided at the bottom of the fixing block 204. The inner diameter of the circular groove 205 is adapted to the outer diameter of connecting post 201 or connecting post 206. At the same time, in order to ensure that the multiple stacked silicon steel sheets 203 can be accurately aligned, a positioning block 208 is fixedly provided on the top surface of each silicon steel sheet 203, and a positioning groove 209 adapted to the shape and size of the positioning block 208 is provided on the bottom surface of the silicon steel sheet 203.

[0031] As another preferred embodiment, in order to clarify the connection relationship of each component in the connecting mechanism 2, a connecting groove 202 is opened at the top of the connecting post 1 201 for the bottom of the connecting post 206 to be inserted and fixed by screwing. The connecting mechanism 2 also includes a top cover 207, which is fixed to the topmost connecting post 206 by a threaded connection.

[0032] As another preferred embodiment, to clarify the installation and adjustment structure of the installation mechanism 3, the number of arc plates 301 of the installation mechanism 3 is two, and they are symmetrically fixed to the bottom of the bottom stator 1. The top of the arc plate 301 has multiple adjustment holes 305 along the length direction. The adjustment bolts 306 pass through the selected adjustment holes 305 in sequence and are threadedly connected to the sliding blocks 303. The installation ring 304 spans across and connects between the two sliding blocks 303.

[0033] Working principle:

[0034] When assembling the stator core, first fix the bottom of the connecting post 201 to the top left and right sides of the bottom stator 1. Then take out the silicon steel sheet 203 with the fixing block 204. Using the circular groove 205 opened at the bottom of the fixing block 204, put the silicon steel sheet 203 on the outer wall of the connecting post 201 to complete the installation of the first layer of silicon steel sheet. At this time, the positioning block 208 at the top of the silicon steel sheet 203 protrudes upward. When it is necessary to increase the stacking height of the silicon steel sheet 203, take out the new silicon steel sheet 203, align the bottom positioning groove 209 with the positioning block 208 at the top of the lower silicon steel sheet 203, and make the positioning block 208 fully inserted into the positioning groove 209, so as to achieve precise positioning between the upper and lower silicon steel sheets 203 and prevent tilting or misalignment during stacking. Repeat this step until the preset core thickness is reached.

[0035] If the required stacking height exceeds the height of a single connecting post 201, the bottom of connecting post 206 is screwed into the connecting groove 202 at the top of connecting post 201, fixing connecting post 206 to the top of connecting post 201, thereby extending the total length of the entire connecting post. The subsequently added silicon steel sheet 203 is fitted onto the outer wall of connecting post 206 through the circular grooves 205 on both sides, and is also aligned between layers through the cooperation of positioning block 208 and positioning groove 209. After all silicon steel sheets 203 are stacked, the top cover 207 is screwed into the top of the top connecting post 206 through a threaded connection. During the downward tightening of the top cover 207, pressure is applied to the top silicon steel sheet 203, thereby firmly pressing and fixing the entire silicon steel sheet stack to the bottom stator 1.

[0036] When the assembled stator core needs to be installed, it is operated by the installation mechanism 3. The arc plate 301 of the installation mechanism 3 is pre-fixed on the front and rear sides of the bottom of the bottom stator 1. The installation ring 304 is connected to the arc plate 301 through the sliding block 303. Since the sliding block 303 can slide inside the sliding groove 302 of the arc plate 301, the lateral position of the installation ring 304 can be easily adjusted to adapt to the installation spacing requirements of different equipment. When the sliding block 303 moves to the appropriate position, the adjusting bolt 306 is selected to the adjusting hole 305 at the corresponding position on the top of the arc plate 301. Then the adjusting bolt 306 is screwed into the adjusting hole 305 and further screwed into the interior of the sliding block 303. The sliding block 303 is limited and fixed by the threaded locking force to prevent the sliding block 303 from moving accidentally in the sliding groove 302, thus ensuring the stability and reliability of the entire stator core installation.
