Description

Technical Field

[0001] The utility model belongs to the technical field of stator processing equipment, in particular to a stator turning pre-assembly machine. Background Art

[0002] The stator pre-shaping machine is a pneumatic device that uses hydraulic technology to pre-shape the stator coils that have been embedded with wires. The main principle is to use the upper and lower molds and the center axis mold to perform internal expansion, external contraction, and upper and lower pressure operations to complete the pre-shaping of the ends and the entire stator coil.

[0003] Patent application number CN201120248217.6 discloses a stator pre-assembly machine comprising a frame with two overlapping, centrally open turntables. The turntables house several centripetally retractable pins. Above and below the turntables, respectively, are a core expansion mechanism and a lower assembly aligned with the core expansion mechanism. Both the core expansion mechanism and the lower assembly can be raised and lowered. This patent simultaneously performs the stator coil shrinking, the exposed root shaping of the wire loop, the external turning of the lower winding package, the shaping of the stator end faces, and the internal expansion, reducing the complexity of the process. However, the fully enclosed clamping mechanism on the turntable, achieved through the collaboration of dozens of pin slots, pin pin slots, and pins, is overly complex, resulting in high production costs, prone to malfunction and damage, and difficult to repair. The pre-assembly requires manual handling by workers, resulting in low processing efficiency. Utility Model Content

[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0022] like Figures 1 to 4As shown, the stator rotation pre-assembly machine comprises a housing structure 100, an upper mold structure 200, and a lower mold structure 300. The housing structure 100 is continuous from front to back, comprising a top plate 120, a bottom plate 130, and two side plates. A control box and a power distribution box are located at the bottom, and feet are located at the four corners of the bottom plate 130. The interior of the housing structure 100 houses the upper mold structure 200 and the lower mold structure 300, which are supported and connected by main guide posts 110 located at the four corners.

[0023] like Figure 2 As shown, the upper mold structure 200 mainly includes, from top to bottom, an upper mold core moving cylinder 210, an upper mold core moving plate 220, an upper mold sleeve fixed plate 230, and its upper structure. The upper mold core moving cylinder 210 is vertically fixed to the box top plate 120. The end of its cylinder rod passes through the box top plate 120 and is fixedly connected to the upper mold core moving plate 220, thereby controlling the upper mold core moving plate 220 to move up and down. An upper inner expanding mold core 221 is formed downward at the bottom center of the upper mold core moving plate 220. The upper inner expanding mold core 221 is an elongated cylindrical structure as a whole. It passes through the mold core hole opened in the center of the upper mold sleeve fixed plate 230. An upper moving plate guide column 222 is provided between the upper mold core moving plate 220 and the upper mold sleeve fixed plate 230. When the cylinder rod of the upper mold core moving cylinder 210 extends downward, the upper mold core moving plate 220 moves downward along the upper moving plate guide column 222 and the main guide column 110, thereby driving the upper internal expansion mold core 221 to extend from the top of the stator coil into its interior to expand it.

[0024] At the bottom of the upper die sleeve fixed plate 230, on both sides of the upper inner expansion die core 221, are provided an upper shaping die sleeve 231, an upper die sleeve moving cylinder 232, and an upper die sleeve slide rail 233. The upper shaping die sleeve 231 is movably connected to the bottom of the upper die sleeve fixed plate 230 via the upper die sleeve slide rail 233. The inner sides of the upper shaping die sleeves 231 on both sides are semicircular arc-shaped, and when combined with each other, a complete die sleeve opening is formed. The upper die sleeve moving cylinder 232 is fixedly connected to the outer wall of the upper shaping die sleeve 231 to control the horizontal movement of the upper shaping die sleeve 231. When the upper inner expansion die core 221 expands the upper end of the stator coil inward, the cylinder rods of the upper die sleeve moving cylinders 232 on both sides extend inward, causing the upper shaping die sleeve 231 to move inward and contract along the upper die sleeve slide rail 233, thereby achieving outward contraction shaping of the outer side of the upper end of the stator coil.

[0025] like Figures 3 and 4As shown, the lower mold structure 300 mainly includes a flip table 310, a lower mold sleeve fixing plate 320, a lower mold core moving plate 330, a lower mold core moving cylinder 340 and a finished product table 350. The flip table 310 is movably installed above the top center of the lower mold sleeve fixing plate 320 through a table bracket. A mold core hole is opened in the center of the lower mold sleeve fixing plate 320. A lower shaping mold sleeve 321, a lower mold sleeve moving cylinder 322 and a lower mold sleeve slide rail 323 are arranged on both sides of the mold core hole between the flip table 310 and the lower mold sleeve fixing plate 320. The lower shaping mold sleeve 321, the lower mold sleeve moving cylinder 322 and the lower mold sleeve slide rail 323 and the structure and operation The operation mode is basically the same as the upper shaping mold sleeve 231, the upper mold sleeve moving cylinder 232 and the upper mold sleeve slide rail 233. The lower shaping mold sleeve 321 is movably connected to the top of the lower mold sleeve fixed plate 320 through the lower mold sleeve slide rail 323. The lower mold sleeve moving cylinder 322 is fixedly connected to the outer side wall of the lower shaping mold sleeve 321. The cylinder rod is extended inward to control the lower shaping mold sleeve 321 to move inward and shrink, thereby realizing the outward shrinkage shaping of the outer side of the lower end of the stator coil.

[0026] A lower moving plate guide post 332 is provided between the lower mold core moving plate 330 and the lower mold sleeve fixed plate 320. A lower internal expansion mold core 331 is formed upward from the top center of the lower mold core moving plate 330. This lower internal expansion mold core 331 is a short columnar structure. When the equipment is not in operation, it is located below the lower mold sleeve fixed plate 320. During operation, the lower internal expansion mold core 331 passes through the mold core hole in the center of the lower mold sleeve fixed plate 320 and extends from the bottom of the stator coil into the interior to expand it. Two sets of lower mold core moving cylinders 340 are fixedly connected between the bottom of the lower mold core moving plate 330 and the box bottom plate 130. They serve to move, support, and balance the lower mold core moving plate 330 and the structure above it.

[0027] A stator mounting hole is provided in the center of the flip table 310 for accommodating the stator coil to be processed. The front and rear edges of the mounting hole are formed with an upwardly protruding annular positioning plate 311. The annular positioning plate 311 is used to position and install the stator to prevent it from being displaced by force during inward expansion and outward contraction pre-shaping. The flip table 310 is movably mounted above the top center of the lower mold sleeve fixing plate 320 via a table bracket. The table bracket includes a front table support bracket 312 and a rear table flip bracket 313. The table support bracket 312 is detachably connected to the flip table 310, and the table flip bracket 313 is rotatably connected to the flip table 310, allowing the flip table 310 to perform flip and rotational motion with its rear edge as the central axis.

[0028] A flip connecting bracket 314 is fixedly connected to the top rear side of the flip table 310, and a flip cylinder 315 installed obliquely upward and rearward is provided on the rear side of the lower mold core moving cylinder 340. The cylinder rod end of the flip cylinder 315 is rotatably connected to the flip connecting bracket 314, and a finished product table 350 is provided on the rear side of the flip table 310 on the lower mold sleeve fixing plate 320. When the flip cylinder 315 extends the cylinder rod, the front end of the flip connecting bracket 314 drives the flip table 310 to descend until the front end of the flip table 310 is placed on the table support bracket 312. At this time, the stator can be pre-processed; when the flip cylinder 315 shortens the cylinder rod, the front end of the flip connecting bracket 314 drives the flip table 310 to flip and rise around its rear edge, and the stator coil is transferred to the finished product table 350 through the annular positioning plate 311. After the finished product table 350 is connected to the conveying structure, the stator can be directly sent to the next processing step, reducing the process of workers manually taking it and improving the stator processing efficiency.

[0029] Further explanation is given, the main column 110 is provided with a guide column sleeve 111 at the connection between the upper mold core moving plate 220, the upper mold sleeve fixed plate 230 and the lower mold core moving plate 330. The guide column sleeve 111 is provided with fastening bolts around the main column 110. When loosened, the position of each layer structure inside the box structure 100 can be adjusted, and when tightened, each layer structure can be relatively fixed on the main column 110.
