Description

Technical Field

[0001] This invention relates to the field of stator core equipment technology, specifically to an automated pressing device for motor stator cores. Background Technology

[0002] The automated pressing equipment for motor stator cores is an automated pressing device for multi-layer silicon steel sheet laminations in motor stators. This equipment can uniformly and physically press and shape multiple sets of laminated silicon steel sheets. Simultaneously, the equipment primarily uses uniform and controlled physical compaction to ensure tight adhesion between the layers of silicon steel sheets, thereby maintaining the integrity of the inter-sheet insulation coating, effectively blocking eddy current generation paths, significantly reducing eddy current losses and heat generation during motor operation, and improving motor efficiency. Furthermore, the equipment can compact and shape loosely stacked silicon steel sheets into a high-strength, rigid whole, enhancing the overall mechanical structural strength of the stator core. This resists the impact of electromagnetic forces, mechanical vibrations, and thermal deformation during motor operation, preventing long-term issues such as silicon steel sheet shifting, loosening, deformation, or even sheet breakage.

[0003] However, existing automated press-fitting equipment for motor stator cores still lacks sufficient integration in the feeding, pressing, positioning, and unloading of silicon steel sheets when pressing and shaping batches of stator cores. This reduces the efficiency of the equipment in pressing and shaping batches of silicon steel sheets. At the same time, the accuracy of real-time positioning feedback for each process in existing automated press-fitting equipment for motor stator cores is also insufficient. Therefore, an automated press-fitting equipment for motor stator cores is needed to solve the problems mentioned above. Summary of the Invention

[0004] The purpose of this invention is to provide an automated pressing device for motor stator cores to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automated pressing device for motor stator cores, comprising a guide slide for supporting and guiding materials, a feeding bin fixedly disposed at the feeding end of the guide slide, a feeding assembly equidistantly slidably engaged inside the feeding bin, and stator silicon steel sheets equidistantly disposed inside the feeding assembly.

[0006] The processing component is fixedly mounted on the upper end face of the guide slide near the middle via an aluminum profile column and a feeding bin. The processing component is used to shape and press-fit the stator silicon steel sheets inside the feeding component.

[0007] The material guiding assembly is fixedly installed on the lower end face of the material guiding slide, and is used to simultaneously feed the shaped stator silicon steel sheet and the feeding assembly.

[0008] Specifically, inside the guide slide, two sets of opposing slotted photoelectric switches are installed opposite the loading component to be pressed. Each set of slotted photoelectric switches has a three-axis cylinder at its upper part, and the power output end of the three-axis cylinder is fixedly connected to both sides of the loading component through a positioning plate. A proximity switch two is installed on the upper end face of the guide slide near the aluminum profile column, and a material guide groove for guiding material is opened in the middle of the inner end face of the guide slide. Proximity switches three are fixedly snapped on both sides of the loading bin near the bottom, and two sets of reinforcing ribs for support are installed on both sides of the loading bin. Two sets of proximity switches one are installed inside the guide slide near the unloading end.

[0009] Specifically, the processing components include a support bracket, an electric cylinder fixedly mounted on the upper part of the support bracket, and a pressing component fixedly mounted on the power output end of the electric cylinder. A transmission component is rotatably engaged at the rear of the support bracket. The electric cylinder drives the transmission component to rotate through the pressing component. The transmission component drives the guide push plate to move linearly back and forth through the guide slide rail and the docking guide seat. Five sets of guide partitions are fixedly arranged at equal intervals at the rear of the guide push plate.

[0010] Specifically, the press assembly includes a press guide seat, five sets of press fixtures fixedly arranged at equal intervals at the bottom of the press guide seat, and a sliding shaft guide seat that is slidably engaged inside the press guide seat through three sets of linear sliding shafts. Both ends of the sliding shaft guide seat are rotatably engaged with limit shafts, and two sets of positioning baffles are provided at the front of the lower end of the press guide seat.

[0011] The transmission assembly includes a transmission shaft and docking flanges fixedly attached to both ends of the transmission shaft. A first swing arm is detachably fixedly attached to the upper part of the docking flange, and a second swing arm is detachably fixedly attached to the lower part of the docking flange. A positioning guide shaft is rotatably attached to the bottom end of the second swing arm.

[0012] Specifically, the feeding assembly includes a feeding fixture, five sets of shaping grooves equidistantly opened on the upper part of the feeding fixture, and positioning slots opened on the upper part of both sides of the feeding fixture. Each positioning slot has two sets of positioning chamfers at its opening, and positioning baffles are provided on both sides of the feeding fixture near the bottom of the positioning slots. A limit slot is opened at the center of the lower end face of the feeding fixture.

[0013] Specifically, the material guiding assembly includes a rodless cylinder, a linear slide rail located on the side of the rodless cylinder, and a linear slider slidably engaged with the lower part of the linear slide rail. The power output end of the rodless cylinder drives the alignment seat to move back and forth at the bottom of the linear slide rail through the cylinder slide and the linear slider. A pen-shaped cylinder is fixedly installed at the bottom of the alignment seat, and a feeding plate is fixedly installed at the power output end of the pen-shaped cylinder.

[0014] Specifically, the electric cylinder drives the pressing guide seat to move up and down at the bottom of the support bracket. The pressing guide seat is adapted to the rotation of the first swing arm through the limiting shaft, and then uses the docking flange as a lever to move the second swing arm back and forth. The second swing arm is adapted to the sliding of the positioning guide shaft and the guide slide rail, and then drives the guide push plate to move back and forth at the bottom of the support bracket. When the pressing guide seat moves down, the pressing guide seat can be engaged with the rotation of the first swing arm through the limiting shaft, thereby driving the second swing arm and the positioning guide shaft to swing, which improves the stability of the subsequent transmission.

[0015] Specifically, the electric cylinder drives five sets of pressing fixtures to position and press the stator silicon steel sheet inside the molding groove through the pressing guide seat. The transmission shaft is rotated and locked to the bottom of the support seat through the bearing seat. When the electric cylinder drives the pressing guide seat to move to the bottom limit, the proximity switch two is directly opposite the positioning baffle one. When the pressing guide seat moves down to the limit, the proximity switch two can detect the positioning baffle one's position. This can improve the stability of the pressing fixture pressing the stator silicon steel sheet and prevent over-limit. It can also facilitate the subsequent detection basis for the pen-shaped cylinder to be positioned and unloaded. This makes it convenient for the pen-shaped cylinder to drive the unloading plate to be inserted into the limit slot to complete the unloading preparation.

[0016] Specifically, the front part of the guide plate is fitted and connected to the feeding fixture, and the guide partition is fitted and connected to the bottom of the feeding bin. The feeding fixture is aligned with the detection opening of the slotted photoelectric switch through the positioning baffle two. The two sets of three-axis cylinders are adapted to the positioning slot through the positioning plate and then slide and insert with the feeding fixture. This can prevent multiple sets of feeding fixtures from simultaneously guiding materials at the bottom of the feeding bin, thus improving the stability of the equipment for feeding.

[0017] Specifically, the rodless cylinder drives the unloading plate to insert into the limiting slot through the pen-shaped cylinder, thereby driving the loading fixture to move inside the guide slide. The unloading plate does not contact the unloading guide groove, which can effectively improve the accuracy of the equipment in unloading and positioning the press-fitted stator silicon steel sheets, and also improve the stability of the unloading from the forming groove.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. This invention is an integrated motor stator core pressing mechanism. When pressing batches of stator silicon steel sheets synchronously, the electric cylinder can drive the pressing guide and pressing fixture to circulate and press and shape the stator silicon steel sheets at the bottom of the support base. At the same time, the pressing guide can be limited by the rotation of the limiting shaft and the first swing arm, thereby synchronously driving the second swing arm and the positioning guide shaft to swing. This allows the positioning guide shaft to simultaneously complete the feeding operation of the feeding fixture when the pressing fixture presses the stator silicon steel sheets, effectively improving the efficiency and stability of the pressing equipment for pressing batches of stator silicon steel sheets.

[0020] 2. This invention is a closed-loop detection device. Proximity switch one, proximity switch two, slotted photoelectric switch and proximity switch three can respectively perform real-time detection of the equipment during material loading, positioning, pressing, unloading positioning, unloading positioning and empty material. This allows the above equipment to maximize the accuracy of the equipment in processing positioning and equipment positioning in each process without increasing the bottleneck time of the pressing process, thereby effectively improving the efficiency and accuracy of the equipment in batch processing of stator silicon steel sheets.

[0021] 3. During transmission, the electric cylinder drives the pressing guide seat to move up and down, allowing the pressing guide seat to drive the pressing fixture to cyclically press the stator silicon steel sheets inside the feeding fixture. Simultaneously, as the pressing guide seat moves up and down, it is limited by the rotation of the limiting shaft and the first swing arm, which in turn synchronously drives the second swing arm and the positioning guide shaft to swing around the transmission clamp shaft. This allows the second swing arm to synchronously drive the guide push plate to feed the feeding fixture and the stator silicon steel sheets one by one through the positioning guide shaft and the limitation of the stator silicon steel sheets. This reduces the processing time of the equipment, improves the power utilization efficiency of the equipment, and thus reduces processing costs. Attached Figure Description

[0040] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments.

[0041] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0042] The invention will be further described below with reference to the accompanying drawings.

[0043] Example 1

[0044] Please see Figure 1-7 The present invention provides an embodiment of an automated pressing device for motor stator cores, comprising a guide slide 10 for supporting and guiding materials, a feeding bin 7 fixedly disposed at the feeding end of the guide slide 10, a feeding assembly 3 equidistantly slidably engaged inside the feeding bin 7, and stator silicon steel sheets 5 equidistantly disposed inside the feeding assembly 3.

[0045] The front end of the guide slide 10 is curved, which facilitates the automatic export of the loading fixture 34 after it has been unloaded into place by gravity, thereby improving the convenience and stability of unloading the loading fixture 34.

[0046] Processing component 2 is fixedly installed on the upper end face of the guide slide 10 near the middle via aluminum profile column 1 and feeding bin 7. Processing component 2 is used to shape and press the stator silicon steel sheet 5 inside the feeding component 3. Processing component 2 is also equipped with four sets of linear bearings, the model of which is LHFCD10, which can provide sufficient linear guidance for the vertical displacement of the pressing guide 221.

[0047] The material guiding component 4 is fixedly installed on the lower end face of the material guiding slide 10, and is used to simultaneously feed the shaped stator silicon steel sheet 5 and the feeding component 3.

[0048] Inside the guide slide 10, directly opposite the loading assembly 3 to be pressed, are two sets of opposing slotted photoelectric switches 14. The model of the slotted photoelectric switch 14 is ZJF38-677-ND. When the guide push plate 27 pushes the loading fixture 34 to the pressing position, the slotted photoelectric switch 14 can detect the position of the positioning baffle 33, and then activate the two sets of three-axis cylinders 12 to facilitate pressing and limiting the loading fixture 34.

[0049] Each set of slotted photoelectric switches 14 is equipped with a three-axis cylinder 12 at its upper part. The power output end of the three-axis cylinder 12 is fixedly connected to both sides of the feeding assembly 3 through a positioning plate 13. A proximity switch 9 is located on the upper end face of the guide slide 10 near the aluminum profile column 1. Two sets of proximity switches 8 are located inside the guide slide 10 near the unloading end.

[0050] Proximity switches 1-8 and 2-9 are fixed on the guide slide 10 by the sensor bracket, while proximity switch 3-15 is locked to the side of the loading bin 7 by a nut. The models of proximity switches 1-8, 2-9 and 3-15 are CR18-8DN, which can improve the accuracy of loading, unloading and positioning detection of internal components of the equipment.

[0051] Furthermore, a material guide groove 11 for guiding materials is provided at the middle of the inner end face of the material guide slide 10. Proximity switches 3 15 are fixedly snapped onto both sides of the feeding bin 7 near the bottom. The proximity switches 3 15 can detect the feeding fixture 34 inside the feeding bin 7 in real time, thereby preventing the feeding bin 7 from being empty and improving the stability of equipment operation.

[0052] Furthermore, two sets of reinforcing ribs 6 are provided on both sides of the feeding hopper 7 for support.

[0053] like Figure 8 and Figure 9 The processing component 2 includes a support bracket 24, an electric cylinder 21 fixedly mounted on the upper part of the support bracket 24, and a pressing component 22 fixedly mounted on the power output end of the electric cylinder 21. The electric cylinder 21 is an economical electric cylinder EMB30, which can effectively improve the accuracy of the electric cylinder 21 driving the pressing guide seat 221 to move up and down, and can also provide sufficient pressure for the pressing fixture 222 to shape.

[0054] The rear of the support bracket 24 is rotatably connected to the transmission component 23. The electric cylinder 21 drives the transmission component 23 to rotate through the pressing component 22. The transmission component 23 drives the guide push plate 27 to move linearly back and forth through the guide slide rail 25 and the docking guide seat 26. Five sets of guide partitions 28 are fixedly arranged at equal intervals at the rear of the guide push plate 27.

[0055] like Figure 10 and Figure 11The press assembly 22 includes a press guide 221, five sets of press fixtures 222 equidistantly fixed at the bottom of the press guide 221, and a slide guide 224 slidably engaged inside the press guide 221 by three sets of linear slide shafts 223.

[0056] The linear slide shaft 223 is fixed inside the press-fit guide seat 221 by a retaining seat. At the same time, the slide shaft guide seat 224 is also provided with a linear bearing adapted to the linear slide shaft 223. The linear bearing is used to improve the stability of the slide shaft guide seat 224 sliding outside the linear slide shaft 223. Meanwhile, the sliding limit between the slide shaft guide seat 224 and the linear slide shaft 223 can provide sufficient guiding space when the limit rotating shaft 225 and the swing arm 232 swing up and down.

[0057] Both ends of the sliding shaft guide seat 224 are rotatably engaged with the limit shaft 225, and two sets of positioning baffles 226 are provided at the front of the lower end of the press-fit guide seat 221.

[0058] like Figure 12 The transmission assembly 23 includes a transmission shaft 231 and mating flanges 233 that are fixedly engaged with both ends of the transmission shaft 231.

[0059] The mating flange 233 is fixed to both sides of the transmission shaft 231 by bolts and threads, which facilitates the subsequent installation and disassembly of the mating flange 233;

[0060] A swing arm 232 is detachably fixed to the upper part of the mating flange 233, and a swing arm 234 is detachably fixed to the lower part of the mating flange 233. A positioning guide shaft 235 is rotatably fixed to the bottom end of the swing arm 234.

[0061] The docking flange 233 can be fixedly installed to the first swing arm 232 and the second swing arm 234 respectively by bolts. This allows subsequent workers to adjust the swing distance between the second swing arm 234 and the first swing arm 232 according to the diameter of the press-fit stator silicon steel sheet 5, thereby adjusting the distance between the guide plate 27 and the feeding fixture 34, and improving the adaptability of the equipment.

[0062] like Figure 13 and Figure 14 The feeding assembly 3 includes a feeding fixture 34, five sets of shaping grooves 35 equidistantly opened on the upper part of the feeding fixture 34, and positioning slots 31 opened on the upper part of both sides of the feeding fixture 34. Multiple sets of positioning ribs are also equidistantly arranged inside the shaping grooves 35. The positioning ribs are used to radially limit the batch stacking of stator silicon steel sheets 5 to prevent the stator silicon steel sheets 5 inside the shaping grooves 35 from rotating radially during subsequent feeding or pressing, which would affect the pressing accuracy.

[0063] Two sets of positioning chamfers 32 are provided at the opening of each set of positioning slots 31, and positioning baffles 33 are provided on both sides of the loading fixture 34 near the bottom of the positioning slots 31. A limit slot 36 is provided at the center of the lower end face of the loading fixture 34. The positioning chamfers 32 can provide sufficient guiding foundation for the insertion and positioning of the positioning plate 13, and improve the fault tolerance and convenience of the positioning plate 13 being inserted into the positioning slot 31.

[0064] like Figure 15 and Figure 16 The material guiding assembly 4 includes a rodless cylinder 41, a linear slide rail 46 disposed on the side of the rodless cylinder 41, and a linear slider 45 slidably engaged with the lower part of the linear slide rail 46. The model of the rodless cylinder 41 is CY1S10H-300_CY1S6. The rodless cylinder can effectively reduce the installation space occupied and improve the compactness of the equipment.

[0065] The power output end of the rodless cylinder 41 drives the alignment seat 43 to move back and forth at the bottom of the linear slide rail 46 through the cylinder slide 42 and the linear slider 45. The linear slider 45 and the linear slide rail 46 are model HGH20CA.

[0066] Furthermore, a pen-shaped cylinder 44 is fixedly installed at the bottom of the positioning card holder 43, and a feeding card plate 47 is fixedly installed at the power output end of the pen-shaped cylinder 44. The model of the pen-shaped cylinder 44 is: MSBL aluminum alloy mini cylinder [MSBL20×50-SUFA].

[0067] like Figure 9 and Figure 10 The electric cylinder 21 drives the pressing guide 221 to move up and down at the bottom of the support bracket 24. The pressing guide 221 is adapted to the rotation of the first swing arm 232 through the limiting shaft 225, and then uses the docking flange 233 as a lever to move the second swing arm 234 back and forth. When the pressing guide 221 moves down, the pressing guide 221 can be engaged with the rotation of the first swing arm 232 through the limiting shaft 225, thereby driving the second swing arm 234 and the positioning guide shaft 235 to swing, which improves the stability of subsequent transmission.

[0068] The second swing arm 234 drives the guide push plate 27 to reciprocate back and forth at the bottom of the support seat 24 through the sliding adaptation of the positioning guide shaft 235 and the guide slide rail 25. The thickness of the guide push plate 27, the thickness of the feeding fixture 34, and the height from the feeding bin 7 to the bottom of the guide slide 10 are all equal, which can improve the stability of the subsequent feeding of materials by the guide push plate 27 driving the feeding fixture 34 to feed materials one by one.

[0069] like Figure 3The front part of the guide plate 27 is fitted and connected to the feeding fixture 34, and the guide partition 28 is fitted and connected to the bottom of the feeding bin 7. This can prevent multiple sets of feeding fixtures 34 from simultaneously guiding materials at the bottom of the feeding bin 7, thus improving the stability of the equipment for feeding.

[0070] like Figure 4 and Figure 13 The loading fixture 34 is aligned with the detection opening of the slotted photoelectric switch 14 via the positioning baffle 2 33, and the two sets of three-axis cylinders 12 are adapted to the positioning slot 31 via the positioning insert plate 13 and then slide into the loading fixture 34. The slotted photoelectric switch 14 can detect the position of the positioning baffle 2 33, thereby detecting the loading position of the loading fixture 34. Subsequently, under the control of the external touch screen module, the three-axis cylinders 12 can be inserted into the positioning slot 31 via the positioning insert plate 13, thereby improving the stability of the loading fixture 34 and improving the stability and accuracy of the subsequent pressing fixture 222 pressing the stator silicon steel sheet 5 inside the molding groove 35.

[0071] The rodless cylinder 41 drives the unloading plate 47 to be inserted into the limiting slot 36 through the pen-shaped cylinder 44, thereby driving the loading fixture 34 to move inside the guide slide 10. The unloading plate 47 does not contact the unloading guide groove 11, which can improve the stability of the unloading transmission of the equipment.

[0072] like Figure 1 and Figure 10 The electric cylinder 21 drives five sets of pressing fixtures 222 to position and press the stator silicon steel sheet 5 inside the forming groove 35 via the pressing guide seat 221. The electric cylinder 21 can drive the pressing guide seat 221 to move stably downward at the bottom of the support bracket 24, improving the accuracy and stability of pressing the stator silicon steel sheet 5.

[0073] like Figure 9 The transmission shaft 231 is rotatably engaged with the bottom of the support base 24 through the bearing seat. The bearing seat can provide sufficient rotation limit for the transmission shaft 231 and improve the transmission stability of the transmission shaft 231.

[0074] like Figure 2 and Figure 10 When the electric cylinder 21 drives the pressing guide 221 to move to the bottom limit, the proximity switch 29 is directly opposite the positioning baffle 226. When the pressing guide 221 moves down to the limit, the proximity switch 29 can detect the positioning baffle 226 in place. This can improve the stability of the pressing fixture 222 pressing the stator silicon steel sheet 5 and prevent over-limit. It can also provide a detection basis for the subsequent unloading positioning of the pen-shaped cylinder 44, making it convenient for the pen-shaped cylinder 44 to drive the unloading plate 47 to be inserted into the limit slot 36 to complete the unloading preparation.

[0075] Working principle: Before use, the operator can guide the feeding assembly 3, which contains a batch of stator silicon steel sheets 5, into the feeding hopper 7. This facilitates the simultaneous pressing of multiple sets of stator silicon steel sheets 5 in the same batch. During the pressing operation of the stator silicon steel sheets 5, if... Figure 8 The operator can activate the electric cylinder 21 via an external touchscreen module. The electric cylinder 21 then drives the bottom pressing guide 221 to move downwards. When the pressing guide 221 moves downwards in a straight line, as... Figure 9 and Figure 11 At this time, the limiting shaft 225 inside the press-fit guide seat 221 can be engaged with the first swing arm 232, thereby driving the docking flange 233 and the transmission shaft 231 to rotate, so that the second swing arm 234 and the positioning guide shaft 235 can oscillate around the transmission shaft 231 as the axis. Figure 8 and Figure 12 When the second swing arm 234 drives the positioning guide shaft 235 to swing backward, the positioning guide shaft 235 can be limited by sliding with the guide slide rail 25, thereby synchronously driving the docking guide seat 26 and the guide push plate 27 to move backward along the inside of the guide slide seat 10. When the guide push plate 27 drives the guide partition 28 to move backward, the guide partition 28 can support the last set of loading fixtures 34 at the bottom of the loading bin 7 until the electric cylinder 21 drives the five sets of pressing fixtures 222 to completely press the stator silicon steel sheets inside the loading fixture 34. At 5 o'clock, the positioning guide shaft 235 drives the guide slide rail 25 and the guide push plate 27 to move backward to the limit position. At the same time, the guide push plate 27 can completely release the limit on the lower opening of the loading bin 7, so that the last set of shaping grooves 35 can fall to the upper part of the guide slide 10 to complete the reserve loading of the next set of shaping grooves 35. Meanwhile, the electric cylinder 21 can continuously press the stator silicon steel sheet 5 inside the shaping groove 35 until the pressing operation of the stator silicon steel sheet 5 inside the loading fixture 34 is completed.

[0076] like Figure 4 and Figure 10 When unloading the press-fitted stator silicon steel sheet 5, when the press-fitting guide 221 is pressed down to the upper part of the stator silicon steel sheet 5 by the electric cylinder 21, the proximity switch 9 can detect the pressing position of the press-fitting fixture 222 through the positioning baffle 226. After sensing that the press-fitting fixture 222 is in place, the proximity switch 9 outputs an electrical signal to the external touchscreen module. Figure 14 and Figure 16 The external touchscreen module can activate the pen-shaped cylinder 44 via the corresponding solenoid valve. At this time, the pen-shaped cylinder 44 can complete the unloading and positioning by inserting the unloading plate 47 into the limiting slot 36. When the pressing fixture 222 completes the pressing of the stator silicon steel sheet 5, and the electric cylinder 21 drives the pressing guide 221 and the pressing fixture 222 to reset, then... Figure 4The proximity switch 9 can again synchronously activate the solenoid valves corresponding to the three-axis cylinder 12 and the rodless cylinder 41 via the external touch screen module. The solenoid valves first activate the two sets of three-axis cylinders 12 to reset the positioning plate 13, thereby releasing the positioning plate 13 from limiting the positioning slot 31. Then, the rodless cylinder 41 is activated. At this time, the rodless cylinder 41 can drive the cylinder slide 42 and the unloading plate 47 to move synchronously towards the unloading port of the guide slide 10. This allows the unloading plate 47 to drive the loading fixture 34 to move to the unloading port of the guide slide 10 via the limiting slot 36. When the loading fixture 34 moves to the unloading port of the guide slide 10, at this time... Figure 3 The proximity switch 8 can detect the position of the loading fixture 34 and then transmit an electrical signal to the touch screen module. The touch screen module can then activate the pen-type cylinder 44 and the rodless cylinder 41 through the solenoid valve to reset, so that the unloading plate 47 first releases the limit on the loading fixture 34, and then the rodless cylinder 41 drives the alignment plate 43 and the unloading plate 47 to reset, which is convenient for the next unloading.

[0077] like Figure 6 and Figure 8 When the feeding fixture 34 is feeding material, the electric cylinder 21 drives the pressing fixture 222 to move down to its limit to press the stator silicon steel sheet 5. At this time, the guide push plate 27 and the guide partition 28 are both located behind the lower opening of the feeding bin 7. When the pressing fixture 222 completes the pressing and reset, the electric cylinder 21 drives the pressing fixture 222 and the pressing guide seat 221 to move up. At this time, the pressing guide seat 221 can connect with the swing arm through the limit pivot 225. The rotation limit of 232, and then the transmission pin 231 as the axis, drives the swing arm 234 and the positioning guide shaft 235 to move forward circumferentially. At this time, the positioning guide shaft 235 drives the guide slide rail 25 to move from back to front, so that the guide slide rail 25 can drive the guide push plate 27 and the guide partition 28 to move forward through the docking guide seat 26. The guide push plate 27 can push the feeding fixture 34 on the upper part of the guide slide 10 forward, such as Figure 1 , Figure 3 and Figure 4 Until the loading fixture 34 is positioned inside the slotted photoelectric switch 14 by the positioning baffle 2 33, the slotted photoelectric switch 14 detects the arrival signal and can simultaneously start the solenoid valves of the two sets of three-axis cylinders 12 through the external touch screen module, so that the two sets of three-axis cylinders 12 can be inserted into the positioning slot 31 through the positioning insert plate 13, thereby completing the rigid limit of the loading fixture 34 and improving the accuracy of the subsequent pressing fixture 222 and the shaping groove 35 coaxial positioning and pressing.

[0078] Both swing arms 232 and 234 can be adjusted to their positions outside the mating flange 233. The feeding distance between swing arms 232 and 234 can be adjusted according to different diameters and sizes of stator silicon steel sheets 5, as well as the feeding fixture 34 that carries the stator silicon steel sheets 5 and the feeding bin 7 used for feeding. This facilitates the processing of other models of stator silicon steel sheets 5. At the same time, the proximity switches 315 on both sides of the feeding bin 7 can provide an empty material warning for the feeding fixture 34 inside the feeding bin 7 to prevent the machine from running idle.

[0079] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
