[0016] The bottom side clamping plates 3041 on both sides are arranged in parallel, and the opposite surfaces of the bottom side clamping plates 3041 on both sides have fitting spaces which are matched with the bottom of the machining module to limit the lifting space.

[0017] Specifically, the staff embeds the whole machining module into the pressing frame 3 from the front, and in the embedding process, the bottom plate 307 of the machining module is correspondingly embedded in the pressing lower die 304. In the process that the bottom plate 307 abuts against the rear abutting plate 3043, the bottom plate 307 first passes through the bottom side clamping plates 3041 on both sides, passes through the fitting spaces in the bottom side clamping plates 3041, and then abuts against the rear abutting plate 3043. At this time, the bottom plate 307 is fixed by the bottom side clamping plates 3041 on both sides and the rear abutting plate 3043, and the position of the up and down movement is limited by the fitting spaces in the bottom side clamping plates 3041. At this time, the front side rotating buckle 3042 is rotated to the front side of the bottom plate 307 to limit the front side, so as to achieve the purpose of limiting the front side, the back side, the side surface and the up and down space of the bottom plate 307.

[0018] In the embodiment, the side limiting pushing member 305 includes a fixed seat 3051, a side limiting cylinder 3052, a top shaft 3053 and a limiting clamping rod 3055. The fixing base 3051 is arranged on the pressing support 301 and located outside the pressing lower die 304, the side limiting air cylinder 3052 is arranged on the fixing base 3051, the top shaft 3053 is connected with the output end of the side limiting air cylinder 3052, the limiting clamping rod 3055 is arranged on the bottom plate 307, one end of the limiting clamping rod 3055 towards the workpiece is provided with the abutting block 3056 arranged in a recess, the other end of the limiting clamping rod 3055 is provided with the elastic connecting plate 3054, and the side limiting air cylinder 3052 drives the top shaft 3053 to push the connecting plate 3054 and drive the abutting block 3056 to abut against the workpiece.

[0019] Specifically, The top shaft 3053 is driven by the side limiting air cylinder 3052 to extend out, and the top shaft 3053 abuts against the connecting plate 3054 in the process of extending out, the connecting plate 3054 is forced to drive the abutting block 3056 to move towards the workpiece, and the abutting block 3056 abuts against the workpiece to achieve the purpose of side limiting.

[0020] In the embodiment, the rear limiting pushing piece 306 includes a rear limiting air cylinder 3061, a vertical rod 3062, a fixing frame 3063, a telescopic abutting plate 3064, a clamping groove 3065, a limiting block 3066 and a stop block 3067. The rear limiting air cylinder 3061 is arranged on the rear side of the pressing support 301, the vertical rod 3062 is arranged on the output end of the rear limiting air cylinder 3061 and faces the workpiece, the fixing frame 3063 is arranged on the buffer pressing plate 312, the clamping groove 3065 is arranged on one end of the telescopic abutting plate 3064 close to the rear limiting air cylinder 3061, and the clamping groove 3065 is matched with the vertical rod 3062. The limiting block 3066 is arranged on the telescopic abutting plate 3064, and the stop block 3067 is arranged on the fixing frame 3063.

[0021] Specifically, One end of the telescopic abutting plate 3064 towards the workpiece abuts to achieve the purpose of limiting the rear side, the side limiting pushing piece 305 limits the lower positioning piece 308, and the rear limiting pushing piece 306 limits the upper positioning piece 309, so that the workpiece is limited before pressing, and the limiting is released during the pressing process, so that the workpiece is not worn or deformed by the limiting part during the pressing process, and the limiting is released as follows during the releasing process. When the press-fit cylinder 302 drives the output shaft 303, the output shaft 303 gradually moves downward, and the movable pressing plate 314 is preferentially abutted, so that the workpiece in the upper working position is continuously moved downward by the movable pressing plate 314, and the second elastic member 313 is first extruded. When the elastic potential energy of the second elastic member 313 is compressed to the limit, the buffer pressing plate 312 drives the first elastic member 311 to compress the elastic potential energy, 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 when the elastic potential energy of the second elastic member 313 is compressed to the limit, the side limiting cylinder 3052 drives the top shaft 3053 to retract, and the connecting plate 3054 is elastically rebounded from the limiting clamping rod 3055, so that the connecting plate 3054 drives the abutting block 3056 to move away from the workpiece, so as to achieve the purpose of releasing the side limiting of the workpiece in the lower working position. Especially important is that when the rear side limiting is released, that is, when the elastic potential energy of the second elastic member 313 is compressed to the limit and the first elastic member 311 is slowly compressed, the fixed frame 3063 descends with the buffer pressing plate 312, and the telescopic abutting plate 3064 on the fixed frame 3063 also descends. When the telescopic abutting plate 3064 descends, the clamping groove 3065 on the limiting abutting plate is driven to descend, and the clamping groove 3065 is gradually inserted into the vertical rod 3062 on the rear limiting cylinder 3061 in the descending process. When the vertical rod 3062 is inserted into the clamping groove 3065, the rear limiting cylinder 3061 drives the vertical rod 3062 to move away from the workpiece, and the vertical rod 3062 drives the telescopic abutting plate 3064 to move away from the workpiece through the matching of the clamping groove 3065, so as to achieve the purpose of releasing the rear side limiting of the workpiece. In the above, the limiting block 3066 on the telescopic abutting plate 3064 abuts against the stop block 3067 on the fixed frame 3063, so that the telescopic abutting plate 3064 cannot continuously extend toward the workpiece, but can only be driven by the rear limiting cylinder 3061 to move away from the workpiece. In summary, the purpose of assembling different processing by embedding the processing module into the press-fit frame 3 is achieved, and how to limit the workpiece and release the limiting is improved, the accuracy and efficiency of the press-fit between the workpieces are improved, the overall structure linkage is precise and complete, and the production efficiency and yield are improved.

[0022] It should be further pointed out that in Figure 1 , mark 2 is a simple press-fit assembly, and does not have a side limiting push member and a rear limiting push member. In the press-fit assembly of mark 3, the side limiting push member and the rear limiting push member are provided. In actual application scenarios, the press-fit assembly of mark 2 is used for press-fitting a rotor into a rear bearing, press-fitting a rotor into an end cover, and press-fitting a magnetic ring, and the like simple press-fitting steps. In the press-fit assembly of mark 3, it is usually necessary to press-fit complex workpieces, such as press-fitting of a stator and a rotor, and riveting. Since the complex press-fit assembly of mark 3 is included in the simple press-fit assembly of mark 2, only the complex press-fit assembly of mark 3 is described in detail in this document.
