Description

Technical Field

[0001] This utility model relates to the field of rotor lamination technology, specifically a rotor lamination for an electric motor. Background Technology

[0002] Rotor laminations for motors are one of the key components in motor manufacturing. They are mainly used to form the rotor core of motors and have excellent magnetic properties and mechanical strength, which can ensure the stability and reliability of motors during high-efficiency operation.

[0003] According to Chinese Publication No. CN221828694U, a rotor lamination for an electric motor includes a rotor lamination body, a shaft hole, and toothed grooves. The shaft hole is located at the center of the rotor lamination body, and toothed grooves are formed on the outer wall of the rotor lamination body. A limiting mechanism is also provided on the outer wall of the rotor lamination body. In use, the limiting mechanism limits the rotor lamination body, preventing it from shifting. This limits the lamination body when stacked together, eliminating the need for individual alignment of the shaft holes during installation, saving time and facilitating installation. An auxiliary mechanism provides rapid heat dissipation, preventing overheating and ensuring proper operation. It also lubricates the motor shaft, preventing the rotor lamination body from obstructing lubrication. Therefore, the invention facilitates heat dissipation and lubrication during use.

[0004] During the stacking process, the limiting device can ensure the accuracy of stacking multiple sets of rotor laminations. However, when the stacked rotor laminations are moved to the installation area, they may tip over due to shaking. This can cause the stacked rotor laminations to fall off, requiring them to be stacked again, which is time-consuming. Utility Model Content

[0005] The purpose of this invention is to provide a rotor lamination for an electric motor, thereby solving the problem mentioned in the background art that requires stacking multiple sets of rotor laminations again, which is time-consuming.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rotor lamination for an electric motor, comprising: a rotor lamination body and a fixing assembly, wherein the fixing assembly is disposed on the outer wall of the rotor lamination body for fixing multiple stacked rotor lamination bodies; the fixing assembly includes a sliding groove formed on the top outer wall of the rotor lamination body, a groove formed on one side of the top of the sliding groove, a positioning groove formed on one side of the bottom of the sliding groove, a circular tube welded to the bottom of the outer wall of the rotor lamination body at the positioning groove, a protrusion welded to the outer wall of the circular tube, a positioning plate welded inside the circular tube, a circular hole formed inside the positioning plate, a guide rod vertically slidably disposed in the circular hole of the positioning plate, and an insertion block welded to the bottom end of the guide rod.

[0007] By adopting the above technical solution, it is possible to fix multiple sets of rotor lamination bodies during the stacking process.

[0008] Preferably, the fixing component further includes a through hole formed at the bottom of the positioning groove, the through hole connecting the positioning groove to the round tube.

[0009] By adopting the above technical solution, the guide rod inside the circular tube can be moved through the through hole.

[0010] Preferably, the fixing component further includes a spring sleeved on the guide rod, with both ends of the spring welded to the outer walls of the plug block and the positioning plate, respectively.

[0011] By adopting the above technical solution, the insertion block can be inserted into the positioning groove by the compression of the spring.

[0012] Preferably, the size of the protrusion is adapted to the size of the groove.

[0013] By adopting the above technical solution, the protrusion can slide vertically into the interior of the groove through the groove, thereby providing the protrusion with subsequent horizontal arc-shaped displacement inside the groove.

[0014] Preferably, the width of the groove is adapted to the diameter of the circular tube, and the top view of the groove is arc-shaped.

[0015] By adopting the above technical solution, the circular tube can stably achieve arc-shaped sliding displacement inside the groove.

[0016] Preferably, the plug-in block consists of two sets of cylindrical blocks with a T-shaped cross-section, and the cylindrical block at the bottom of the plug-in block is adapted to the inner diameter of the positioning groove.

[0018] In summary, this utility model has the following beneficial effects: by providing a fixing component, when multiple sets of rotor lamination bodies are stacked, the fixing component can quickly position and fix the multiple sets of rotor lamination bodies. By fixing the multiple sets of rotor lamination bodies to each other, when the stacked multiple sets of rotor lamination bodies are tilted due to shaking, the multiple sets of rotor lamination bodies fixed to each other by the fixing component can still maintain their original stacked state during the tilting process, providing stable fixation before the multiple sets of rotor lamination bodies are installed and connected.

[0026] 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.

[0027] The following is in conjunction with the appendix Figure 1-6 The embodiments of this utility model will be described in further detail.

[0028] Please see Figures 1-6 This embodiment provides a technical solution: a rotor lamination for an electric motor, comprising: a rotor lamination body 1 and a fixing assembly 2;

[0029] The rotor lamination body 1 is mainly used to form the rotor core of the motor. The lamination is made of high-quality cold-rolled silicon steel sheet material, which has excellent magnetic properties and mechanical strength, and can ensure the stability and reliability of the motor during high-efficiency operation. The above is the existing technology, and will not be repeated below.

[0030] The fixing assembly 2 is disposed on the outer wall of the rotor lamination body 1 for fixing multiple stacked rotor lamination bodies 1. The fixing assembly 2 includes a groove 201 formed on the top outer wall of the rotor lamination body 1, a recess 202 formed on one side of the top of the groove 201, a positioning groove 203 formed on one side of the bottom of the groove 201, a circular tube 205 welded to the bottom of the outer wall of the rotor lamination body 1 at the positioning groove 203, a protrusion 206 welded to the outer wall of the circular tube 205, and a protrusion 206 welded to the outer wall of the circular tube 205. The positioning plate 207 inside the 05 has a round hole. A guide rod 208 and a plug block 209 welded to the bottom of the guide rod 208 are vertically slidably installed in the round hole of the positioning plate 207. A through hole 204 is opened at the bottom of the positioning groove 203, which connects the positioning groove 203 to the round tube 205. A spring 210 is sleeved on the guide rod 208. The two ends of the spring 210 are welded to the plug block 209 and the outer wall of the positioning plate 207, respectively.

[0031] The dimensions of the protrusion 206 are matched with the dimensions of the groove 202, the width of the slide 201 is matched with the diameter of the round tube 205, and the top view of the slide 201 is arc-shaped. The plug block 209 is composed of two sets of cylindrical blocks with a T-shaped cross section, and the cylindrical block at the bottom of the plug block 209 is matched with the inner diameter of the positioning groove 203.

[0032] The implementation principle of this utility model for a rotor lamination for an electric motor is as follows:

[0033] First, during the stacking of multiple sets of rotor lamination bodies 1, the protrusion 206 of one set of rotor lamination bodies 1 is inserted into the groove 202 of another set of rotor lamination bodies 1. After the protrusion 206 slides into the groove 202, the protrusion 206 and the round tube 205 welded to the outer wall of the protrusion 206 slide together in the slide groove 201 by rotating clockwise. At this time, the slide groove 201 can be used to limit the protrusion 206, thereby positioning the round tube 205 inside the slide groove 201.

[0034] Secondly, when the circular tube 205 in the slide groove 201 rotates to the positioning groove 203, the spring 210 at the bottom of the positioning plate 207 inside the circular tube 205 uses its own elastic force to squeeze and push the insertion block 209. At this time, the insertion block 209 moves vertically downward in a stable manner inside the circular hole of the positioning plate 207 through the guide rod 208, so that the insertion block 209 can be inserted into the positioning groove 203 for fixation during the movement, so that the two sets of stacked rotor lamination bodies 1 can be fixed together. The multiple sets of rotor lamination bodies 1 can be connected to each other in the same way during the stacking process.

[0035] Finally, when one of the rotor lamination bodies 1 is damaged and needs to be disassembled and replaced, the guide rod 208 inside the round tube 205 can be observed through the through hole 204 opened in the positioning groove 203. The guide rod 208 is moved by vertically pulling it through the through hole 204. At this time, the plug block 209 connected to the guide rod 208 is no longer pulled by the spring 210. The plug block 209 is no longer inserted into the positioning groove 203. By rotating the round tube 205 and the protrusion 206 connected to the outer wall counterclockwise, the protrusion 206 and the round tube 205 are removed from the groove 202 of the slide groove 201, so that the two sets of rotor lamination bodies 1 can be separated.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
