[0002] An explosion-proof three-phase asynchronous motor is a type of electric motor specifically designed for flammable and explosive environments. Its core function is to prevent internal electrical sparks or high temperatures from igniting surrounding flammable gases or dust through a special structure, thereby ensuring safe operation in hazardous locations.
[0003] The stator and rotor of an explosion-proof three-phase asynchronous motor are its core components. They are similar in structure to ordinary three-phase asynchronous motors, but they are specially reinforced in design to meet explosion-proof requirements.
[0004] The stator and rotor lamination processing technology of explosion-proof three-phase asynchronous motors is a key part of their manufacturing process, involving high-precision stamping, material selection and explosion-proof design.
[0005] Conventional stator and rotor lamination processing equipment often faces numerous limitations when processing stator and rotor laminations for explosion-proof three-phase asynchronous motors. Conventional equipment lacks stability, struggling to maintain stability in complex processing environments. This can lead to vibrations during processing, affecting the machining accuracy and compromising the quality of the laminations. Furthermore, conventional equipment lacks flexibility, unable to adjust the position and angle of the processed components according to different processing requirements, making it difficult to adapt to the processing of stator and rotor laminations of various specifications and shapes for explosion-proof three-phase asynchronous motors. Utility Model Content
[0006] The purpose of this invention is to provide an explosion-proof three-phase asynchronous motor stator and rotor lamination processing device to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an explosion-proof three-phase asynchronous motor stator and rotor lamination processing device, comprising a device frame and a lifting mechanism. The lifting mechanism is vertically installed on one vertical side of the device frame, and a grinding mechanism is connected and installed in the middle of the lifting mechanism. A lamination fixing frame assembly is installed at the horizontal end of the device frame. The lifting mechanism includes a lifting screw, an upper stabilizing frame, a servo motor, and a lower stabilizing frame. The upper stabilizing frame is provided at the upper end of the lifting screw, and the servo motor is vertically installed at the top of the upper stabilizing frame. The lower stabilizing frame is installed at the lower end of the lifting screw.
[0008] Furthermore, the device structure includes a base, a bracket, a first guide rail, and a second guide rail. The bracket is vertically mounted on the top of one end of the base, and the first guide rail is vertically mounted on the front surface of the bracket. The second guide rail is horizontally mounted symmetrically on the top surface of the base.
[0009] Furthermore, the base and the bracket are welded together, and both ends of the base are provided with holes for bolt installation and fixing. The lifting screw and the first guide rail are parallel to each other.
[0010] Furthermore, the power output end at the bottom of the servo motor is connected to the top of the lifting screw via a coupling, and the upper and lower ends of the lifting screw are connected to the upper and lower stabilizers via bearing seat structures. The upper and lower stabilizers are respectively installed at the upper and lower ends of the bracket.
[0011] Furthermore, the grinding mechanism includes a movable seat, an electric rotary seat, an electric joint, a shock absorber, a direct drive motor, and a grinding wheel. The electric rotary seat is installed on the front side of the movable seat, and the electric joint is connected to the front side of the electric rotary seat. The shock absorber is installed at the end of the electric joint away from the electric rotary seat, and the direct drive motor is vertically installed through the top of the shock absorber. At the same time, the grinding wheel is connected to the bottom power output end of the direct drive motor through a coupling.
[0012] Furthermore, the shock absorber frame is made of damping alloy material, and four diagonal holes for bolt installation are provided at the connection between the shock absorber frame and the electric joint. The movable seat is connected to the first guide rail and the lifting screw by a slotted embedded structure and a threaded connection.
[0013] Furthermore, the lamination fixing frame assembly includes an electric rotating table, a rotating column, a fixed plate, a movable table, and positioning bolts. The top power output end of the electric rotating table is vertically connected to the rotating column via a coupling, and the upper and lower ends of the rotating column are threadedly connected to the fixed plate. The movable table is installed at the bottom of the electric rotating table, and the bottom front and rear ends of the movable table are symmetrically and vertically threaded with positioning bolts.
[0014] Furthermore, the moving stage and the second guide rail are connected to each other using a slotted embedded structure, and the moving stage and the electric rotating stage are fixedly connected.
[0015] This utility model provides an explosion-proof three-phase asynchronous motor stator and rotor lamination processing device, which has the following beneficial effects: 1. This utility model, through the coordinated operation of the device frame and the lifting mechanism, achieves precise vertical lifting control of the grinding mechanism. The device frame, as the basic support structure of the entire device, provides a stable mounting platform for other components. Its design directly affects the processing accuracy and stability of the entire device. The lifting screw in the lifting mechanism, driven by a servo motor, can precisely control the lifting height of the grinding mechanism. The upper and lower stabilizing frames ensure the stability of the lifting screw during operation, avoiding processing errors caused by vibration. This precise lifting control allows the grinding mechanism to meet different processing requirements, including those for explosion-proof three-dimensional grinding machines. The stator and rotor laminations of the asynchronous motor undergo precise grinding, effectively improving the processing quality of the laminations. Furthermore, the base and support are connected by welding, ensuring the overall strength and rigidity of the device's structural components. This allows the entire device to withstand significant external forces during processing without deformation. Holes at both ends of the base facilitate bolt installation, ensuring the device's stability during operation. The lifting screw and the first guide rail are parallel to each other, guaranteeing the linear motion accuracy of the grinding mechanism during lifting and avoiding jamming or offset caused by non-parallelism between the screw and guide rail, further improving processing accuracy.
[0016] 2. This utility model utilizes the combined use of a grinding mechanism and a punch fixing frame assembly. The movable seat in the grinding mechanism can move horizontally on the first guide rail, and combined with the vertical lifting function of the lifting mechanism, the grinding mechanism can flexibly adjust its position in three-dimensional space, thereby comprehensively grinding different parts of the punch. The electric rotary seat and electric joint further increase the flexibility of the grinding mechanism, enabling the grinding wheel to grind the punch at different angles to meet various complex processing requirements. The shock absorption frame is made of damping alloy material, which can effectively absorb the vibration generated during the grinding process, reduce the impact of vibration on processing accuracy, and also reduce noise and improve the working environment. The direct drive motor directly drives the grinding wheel to rotate, which has the advantages of high transmission efficiency and fast response speed, ensuring the stability of the grinding wheel when rotating at high speed and improving grinding efficiency and quality.
[0017] 3. In this utility model, the lamination fixing frame assembly is responsible for fixing and positioning the stator and rotor laminations of the explosion-proof three-phase asynchronous motor. The electric rotary table can drive the rotating column to rotate, thereby causing the laminations fixed on the rotating column to rotate, which facilitates the grinding mechanism to grind each surface of the laminations. The fixing plate is installed on the rotating column through a threaded connection, which can firmly fix the laminations and prevent the laminations from shifting during the grinding process. The moving table can move horizontally on the second guide rail, which facilitates the adjustment of the position of the laminations and makes them better match the grinding mechanism. The positioning bolt is used to fix the position of the moving table and ensure the stability of the laminations during the grinding process. This design of the lamination fixing frame assembly can adapt to the processing needs of laminations of different sizes and shapes, and improves the versatility and practicality of the device.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0021] like Figures 1 to 5As shown, an explosion-proof three-phase asynchronous motor stator and rotor lamination processing device includes a device frame 1 and a lifting mechanism 2. The lifting mechanism 2 is vertically installed on the vertical side of the device frame 1, and a grinding mechanism 3 is connected and installed in the middle of the lifting mechanism 2. A lamination fixing frame group 4 is installed on the horizontal end of the device frame 1. The lifting mechanism 2 includes a lifting screw 201, an upper stabilizer 202, a servo motor 203, and a lower stabilizer 204. The upper stabilizer 202 is provided at the upper end of the lifting screw 201, and the top of the upper stabilizer 202... A servo motor 203 is vertically mounted on the base. A lower stabilizer 204 is mounted on the lower end of the lifting screw 201. The power output end of the servo motor 203 is connected to the top end of the lifting screw 201 via a coupling. The upper and lower ends of the lifting screw 201 are connected to the upper stabilizer 202 and the lower stabilizer 204 via bearing seats. The upper stabilizer 202 and the lower stabilizer 204 are respectively mounted on the upper and lower ends of the bracket 102. The device frame component 1 includes a base 101, a bracket 102, a first guide rail 103, and... The second guide rail 104, the support 102 is vertically installed at the top of one end of the base 101, and the first guide rail 103 is vertically installed on the front surface of the support 102. The second guide rail 104 is horizontally installed symmetrically on the top surface of the base 101. The base 101 and the support 102 are welded together, and both ends of the base 101 are provided with holes for bolt installation and fixing. The lifting screw 201 and the first guide rail 103 are parallel to each other. The lifting screw 201 rotates under the drive of the servo motor 203. Its rotational motion is converted into linear motion through the bearing seat structure between the upper stabilizer 202 and the lower stabilizer 204, thereby driving the grinding mechanism 3 to accurately lift and lower in the vertical direction. This ensures that the grinding mechanism 3 can accurately adjust its height position according to different processing requirements to achieve precise grinding of different parts of the stator and rotor laminations of the explosion-proof three-phase asynchronous motor. At the same time, the first guide rail 103 provides a horizontal track for the moving seat 301, so that the grinding mechanism 3 can also be flexibly adjusted in the horizontal direction. The movable base 301 and the first guide rail 103 are connected by a slotted embedded structure. This connection method not only ensures the stable sliding of the movable base 301 on the first guide rail 103, but also facilitates disassembly and maintenance.
[0022] like Figures 1 to 5As shown, the grinding mechanism 3 includes a movable base 301, an electric rotary base 302, an electric joint 303, a shock absorber 304, a direct drive motor 305, and a grinding wheel 306. The electric rotary base 302 is mounted on the front side of the movable base 301, and the electric joint 303 is connected to the front side of the electric rotary base 302. A shock absorber 304 is mounted on the end of the electric joint 303 away from the electric rotary base 302, and the direct drive motor 305 is vertically mounted through the top of the shock absorber 304. The grinding wheel 306 is connected to the bottom power output end of the direct drive motor 305 via a coupling. The shock absorber 304… Made of damping alloy material, the shock absorber 304 and the electric joint 303 are provided with holes at the four opposite corners for bolt installation. The moving seat 301 is connected to the first guide rail 103 and the lifting screw 201 by a slotted embedded structure and a threaded connection. The rotation function of the electric rotary seat 302 can drive the electric joint 303 and its end shock absorber 304, direct drive motor 305 and grinding wheel 306 to rotate in the horizontal plane, thereby changing the grinding direction of the grinding wheel 306 to meet the grinding needs of different angles. The electric joint 303 further enhances the flexibility of the grinding mechanism 3. It can drive the shock absorber 304, the direct drive motor 305 and the grinding wheel 306 to swing at a certain angle in the vertical plane, so that the grinding wheel 306 can grind at an angle that is closer to the surface of the stamping. Especially for some stampings with complex curved shapes, this swing function can ensure that the grinding wheel 306 maintains better contact with the surface of the stamping, thereby improving the grinding effect and processing quality.
[0023] like Figures 1 to 5As shown, the lamination fixing frame assembly 4 includes an electric rotary table 401, a rotating column 402, a fixed plate 403, a movable table 404, and positioning bolts 405. The top power output end of the electric rotary table 401 is vertically connected to the rotating column 402 via a coupling, and the upper and lower ends of the rotating column 402 are threadedly connected to the fixed plate 403. The movable table 404 is installed at the bottom of the electric rotary table 401, and the bottom front and rear ends of the movable table 404 are symmetrically and vertically threaded with positioning bolts 405. The movable table 404 and the second guide rail 104 are connected to each other using a slotted embedded structure, and the movable table 404 and the electric rotary table 401 are fixedly connected. The rotation function of the electric rotary table 401 can drive the rotating column 402 and the laminations fixed on the rotating column 402 to rotate. In this way, the grinding mechanism 3 can uniformly grind all surfaces of the punch, eliminating the need for frequent manual adjustments to the punch position and improving processing efficiency. The fixed plate 403 is securely mounted on the rotating column 402 via a threaded connection. Its design allows it to fit tightly against the punch, effectively preventing displacement or loosening of the punch during grinding and ensuring grinding accuracy and stability. The moving table 404 is connected to the second guide rail 104 using a slotted embedded structure, allowing the moving table 404 to move smoothly and horizontally on the second guide rail 104. This facilitates adjusting the position of the punch according to processing requirements, ensuring better alignment and cooperation with the grinding mechanism 3. The positioning bolt 405 is used to securely fix the moving table 404 to the second guide rail 104 after the position of the moving table 404 has been adjusted, preventing the moving table 404 from moving due to vibration during grinding.
[0024] In summary, as Figures 1 to 5 As shown, when using the explosion-proof three-phase asynchronous motor stator and rotor lamination processing device, the explosion-proof three-phase asynchronous motor stator and rotor laminations to be processed are first placed on the rotating column 402 of the lamination fixing frame group 4, and then the two sets of fixing plates 403 are rotated up and down to fix them firmly to prevent displacement during the grinding process. Next, according to the processing requirements of the stamping, the servo motor 203 is started to drive the lifting screw 201 to rotate. Through the bearing seat structure between the upper stabilizer 202 and the lower stabilizer 204, the rotational motion is converted into linear motion, thereby driving the grinding mechanism 3 to perform precise lifting and lowering in the vertical direction and adjust to the appropriate height position. Meanwhile, the movable seat 301 can move horizontally on the first guide rail 103. Combined with the vertical lifting function of the lifting mechanism 2, the grinding mechanism 3 can flexibly adjust its position in three-dimensional space to perform comprehensive grinding on different parts of the punch. During the grinding process, the electric rotary seat 302 and the electric joint 303 further increase the flexibility of the grinding mechanism 3, enabling the grinding wheel 306 to grind the punch at different angles to meet various complex processing requirements. Since the shock absorber 304 is made of damping alloy material, it effectively absorbs the vibration generated during the grinding process and reduces the impact of vibration on the processing accuracy. At the same time, the direct drive motor 305 directly drives the grinding wheel 306 to rotate, ensuring the stability of the grinding wheel 306 when rotating at high speed. If it is necessary to grind different surfaces of the punch, the electric rotary table 401 can be started to drive the rotating column 402 to rotate, thereby causing the punch fixed on the rotating column 402 to rotate, which facilitates the grinding mechanism 3 to perform comprehensive processing. If it is necessary to adjust the position of the stamping in the horizontal direction, it can be achieved by moving the moving table 404 horizontally on the second guide rail 104. After adjusting to the appropriate position, the moving table 404 is fixed with the positioning bolt 405 to ensure the stability of the stamping during the grinding process. The entire processing process is simple to operate and can adapt to the processing needs of stampings of different sizes and shapes, thus improving the versatility and practicality of the device.
