Description

Technical Field

[0001] This application relates to the field of motor component processing equipment technology, and in particular to a motor component press-fitting machine. Background Technology

[0002] Motor component press fitting machines are specialized equipment used for the precision press fitting of key components such as motor stators and rotors. By applying pressure, they ensure a tight fit between components to improve motor performance and reliability. This industry originated in the early 20th century with manual operation, featuring simple structures and single functions. After the 1980s, it entered a period of rapid growth with the development of industrial automation, resulting in improved press fitting accuracy and efficiency. In the 21st century, driven by the demands of new energy vehicles, wind power generation, and industrial automation, it has gradually formed a high-end, intelligent, and green industrial structure.

[0003] The technical classifications of press machines include general-purpose, special-purpose, and automated types. Their core principles rely on power and drive transmission systems, using actuators to achieve linear or rotary pressing, and on control systems to adjust parameters. However, general-purpose press machines still have significant drawbacks: traditional mechanical positioning methods result in insufficient precision in pressing displacement control and difficulty in adjustment; reliance on manual positioning and pushing reduces automation and increases workload; the pressing process lacks real-time monitoring, making it impossible to synchronously detect the pressing force-displacement change curve, requiring additional quality inspection equipment; after pressing, uneven stress distribution often leads to uneven mating surfaces, necessitating repeated pressing and affecting efficiency; high heat generated during motor braking exacerbates component wear, shortens equipment lifespan, and increases maintenance costs; and semi-automated designs cannot support simultaneous dual-station operation, limiting capacity increases. Summary of the Invention

[0004] This application aims to address the technical problems of insufficient accuracy and difficulty in adjusting the press-in displacement control caused by traditional mechanical positioning methods; reliance on manual positioning and pushing, which reduces automation and increases workload; lack of real-time monitoring during the pressing process, which makes it impossible to synchronously detect the pressing force-displacement change curve and requires additional quality inspection equipment; uneven stress distribution of pressed parts often leads to uneven mating surfaces, requiring repeated pressing and affecting efficiency; high heat generated during motor braking exacerbates component wear, shortens equipment life, and increases maintenance costs; and semi-automated designs cannot support dual-station synchronous operation, limiting capacity improvement.

[0038] Example 1

[0039] A press-fitting machine for motor components, the press-fitting machine performing a press-fitting operation on workpieces, the press-fitting machine comprising:

[0040] Machine base 1, the top of which is the processing surface;

[0041] The press frame 3 includes a press bracket 301, a press cylinder 302, and an output shaft 303.

[0042] The press-fit bracket 301 is disposed on the processing surface, the press-fit cylinder 302 is disposed on the top of the press-fit bracket 301, one end of the output shaft 303 is disposed on the press-fit cylinder 302, and the other end of the output shaft 303 passes through the top of the press-fit bracket 301 and extends downward toward the processing surface.

[0043] The limiting device includes a press-fit lower mold 304, a side limiting pusher 305, and a rear limiting pusher 306;

[0044] The pressing lower mold 304 includes a bottom side clamping plate 3041, a rear side abutting plate 3043, and a front side rotating buckle 3042. With the side closest to the worker as the front side, the rear side abutting plate 3043 is located on the rear side of the bottom of the pressing bracket 301. The bottom side clamping plates 3041 are respectively located on the left and right sides of the bottom of the pressing bracket 301 and are perpendicular to the rear side abutting plate 3043. The front side rotating buckle 3042 is located on the bottom side clamping plate 3041 and is located at the end facing the worker. The rear side abutting plate 3043, the bottom side clamping plates 3041 on both sides, and the front side rotating buckle 3042 form a rectangular recessed structure that surrounds three sides.

[0045] The side limiting pusher 305 and the rear limiting pusher 306 are respectively located on the left and right sides and the rear side of the press-fit bracket 301.

[0046] The processing module includes a base plate 307, a lower positioning component 308, an upper positioning component 309, a side support rod 310, a movable pressure plate 314, a first elastic component 311, a second elastic component 313, and a buffer pressure plate 312.

[0047] The base plate 307 is embedded in the press-fit lower mold 304 and fixed. The side support rods 310 are respectively disposed on both sides of the base plate 307 and are perpendicular. The buffer plate 312 is connected to the side support rods 310 and is parallel to the base plate 307. The two ends of the first elastic member 311 are respectively connected to the base plate 307 and the buffer plate 312.

[0048] The movable pressure plate 314 is disposed on the buffer pressure plate 312, the second elastic member 313 is disposed between the movable pressure plate 314 and the buffer pressure plate 312, the lower positioning member 308 is disposed on the base plate 307, the upper positioning member 309 is disposed on the movable pressure plate 314, the lower positioning member 308 and the upper positioning member 309 face each other and are aligned, the output shaft 303 is connected to the movable pressure plate 314, and the pressing cylinder 302 drives the output shaft 303 to move the movable pressure plate 314 and the buffer pressure plate 312 up and down.

[0049] The bottom side plates 3041 on both sides are arranged in a parallel structure, and the opposite side of the bottom side plates 3041 on both sides has a fitting space, which is adapted to the bottom of the processing module to limit the lifting space.

[0050] Specifically, the worker embeds the entire processing module into the pressing frame 3 from the front. During the embedding process, the base plate 307 of the processing module is correspondingly embedded in the lower pressing mold 304, wherein:

[0051] During the process of the base plate 307 abutting against the rear abutting plate 3043, it first passes through the bottom side clamping plates 3041 on both sides. When passing through the bottom side clamping plates 3041, it needs to pass through the fitting space of the bottom side clamping plates 3041 and then abut against the rear abutting plate 3043. At this time, the base plate 307 has its side and rear space fixed by the bottom side clamping plates 3041 on both sides and the rear abutting plate 3043, and its up and down swaying position is restricted by the fitting space on the bottom side clamping plates 3041. At this time, the front rotating buckle 3042 is rotated to the front of the base plate 307 to achieve the purpose of restricting the front side, thereby achieving the purpose of restricting the front, rear, side and up and down space of the base plate 307 in all directions.

[0052] In this embodiment, the side limiting pusher 305 includes a fixed base 3051, a side limiting cylinder 3052, a top shaft 3053, and a limiting lever 3055;

[0053] The fixed seat 3051 is disposed on the press-fit bracket 301 and located outside the press-fit lower mold 304. The side limiting cylinder 3052 is disposed on the fixed seat 3051. The top shaft 3053 is connected to the output end of the side limiting cylinder 3052. The limiting rod 3055 is disposed on the base plate 307. The end of the limiting rod 3055 facing the workpiece has a recessed abutment block 3056. The other end of the limiting rod 3055 is provided with an elastic connecting plate 3054. The side limiting cylinder 3052 drives the top shaft 3053 to push the connecting plate 3054, causing the abutment block 3056 to abut against the workpiece.

[0054] Specifically,

[0055] The top shaft 3053 is extended by the side limiting cylinder 3052. During the extension process, the top shaft 3053 will abut against the receiving plate 3054. The receiving plate 3054 will be forced to move the abutment block 3056 toward the workpiece. The abutment block 3056 abuts against the workpiece to achieve the purpose of side limiting.

[0056] In this embodiment, the rear limiting pusher 306 includes a rear limiting cylinder 3061, a vertical rod 3062, a fixing frame 3063, a telescopic stop plate 3064, a slot 3065, a limiting block 3066, and a stop block 3067.

[0057] The rear limiting cylinder 3061 is located on the rear side of the press-fit bracket 301, the upright 3062 is located at the output end of the rear limiting cylinder 3061 facing the workpiece, the fixing bracket 3063 is located on the buffer plate 312, and the slot 3065 is located at one end of the telescopic abutment 3064 near the rear limiting cylinder 3061. The slot 3065 is adapted to the upright 3062.

[0058] The limiting block 3066 is disposed on the telescopic abutment 3064, and the stop block 3067 is disposed on the fixing frame 3063.

[0059] Specifically,

[0060] The telescopic stop plate 3064 abuts against one end of the workpiece to restrict the rear side. The side limiting pusher 305 restricts the lower positioning member 308, and the rear limiting pusher 306 restricts the upper positioning member 309. These restrictions are implemented before press-fitting. During press-fitting, the restrictions need to be released to prevent wear between the workpiece and the limiting components or deformation of the limiting components due to pressure. The process of releasing the restrictions is as follows:

[0061] When the pressing cylinder 302 drives the output shaft 303, the output shaft 303 gradually moves downward and will first abut against the movable pressure plate 314. The movable pressure plate 314 drives the workpiece in the upper working position to continue to move downward, and will first squeeze the second elastic element 313. When the elastic potential energy of the second elastic element 313 is compressed to the limit, it will drive the buffer pressure plate 312 to compress the elastic potential energy of the first elastic element 311, so as to gradually press the workpiece in the upper working position and the workpiece in the lower working position together. At the same time as the elastic potential energy of the second elastic element 313 is compressed to the limit, the side limiting cylinder 3052 will drive the top shaft 3053 to retract, and the connecting plate 3054 will cause the abutment block 3056 to move away from the workpiece due to the elastic rebound of the limiting rod 3055, so as to release the side limiting of the workpiece in the lower working position.

[0062] Most importantly, when the rear limit is released, that is, when the elastic potential energy of the second elastic element 313 is compressed to the limit and the first elastic element 311 is slowly compressed, the fixing frame 3063 will descend with the buffer plate 312, and the telescopic abutment 3064 on the fixing frame 3063 will also descend. When the telescopic abutment 3064 descends, it will drive the slot 3065 on the limit abutment to descend. During the descent, the slot 3065 will be gradually inserted by the upright rod 3062 on the rear limit cylinder 3061. When the upright rod 3062 is inserted into the slot 3065, the rear limit cylinder 3061 will drive the upright rod 3062 to move away from the workpiece. The upright rod 3062, through its adaptation with the slot 3065, will drive the telescopic abutment 3064 away from the workpiece, so as to achieve the purpose of releasing the rear limit on the workpiece.

[0063] In the above, the limiting block 3066 on the telescopic stop plate 3064 will abut against the stop block 3067 on the fixed frame 3063. Therefore, the telescopic stop plate 3064 cannot extend continuously toward the workpiece, but can only be driven by the rear limiting cylinder 3061 to move away from the workpiece.

[0064] In summary, the process achieves the purpose of embedding the processing module into the press frame 3 for different processing, and improves the accuracy and efficiency of press-fitting between workpieces by limiting and releasing the workpieces. The overall structure is precise and complete, which can improve production efficiency and yield.

[0065] It should also be noted that, in Figure 1 In the diagram, marking 2 represents a simple press-fit assembly without side and rear limiting pushers, while marking 3 represents a press-fit assembly with both side and rear limiting pushers. In practical applications, marking 2 is used for simple press-fit steps such as press-fitting the rotor into the rear bearing, the rotor into the end cover, and the magnetic ring. Marking 3 is typically used for press-fitting complex workpieces, such as press-fitting the stator and rotor, riveting, etc. Since marking 3 is a complex press-fit assembly that is included in marking 2, this paper will only provide a detailed description of marking 3's complex press-fit assembly.
