After the pressure plate is cast, it needs to be rough machined on both sides first, and then it needs to be precision machined. During the machining process, multiple machine tools are required to process the automotive clutch pressure plate.

During the waiting time intervals, the waiting intervals cannot be effectively utilized, and the stress generated during processing cannot be effectively removed.

[0023] According to the above technical solution, the flipping motor, inner diameter electric push rod, pressure sensor, outer diameter electric push rod, clamping vibration motor, infusion pump, swing motor, transverse electric slide rail, lifting electric push rod, longitudinal electric slide rail, electric cutting tool, suspension electric slide rail, discharge motor, guide electric push rod, adjusting electric push rod, palletizing electric push rod, discharge vibration motor, driven gear, drive motor, heating wire and air pump input terminal are electrically connected to the external power supply output terminal through the controller.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. Equipped with a pressure plate processing component, the inner and outer diameter electric push rods in the middle of the flipping plate fix the pressure plate. The transverse electric slide rail, lifting electric push rod, and longitudinal electric slide rail on one side of the flipping plate run, and the electric cutting tool cuts one side of the pressure plate. After one side of the pressure plate is processed, the flipping motor drives the flipping plate to rotate, transferring the other side of the pressure plate to the processing element corresponding to the fixed frame for processing. Compared with the existing processing device, there is no need to use a separate flipping mechanism to flip the pressure plate, and there is no need for multiple transfers in the middle. The pressure plate processing speed is faster and the production efficiency is higher.

[0026] When the processing element corresponding to the fixed frame processes the other side of the pressure plate, the pneumatic gripper can transport the pressure plate conveyed by the conveyor belt to the processing element corresponding to the flipping plate for processing, ensuring the continuity of pressure plate processing. When processing the pressure plate, the side of the pressure plate with a longer processing time is placed on the processing element corresponding to the fixed frame, and the side of the pressure plate with a shorter processing time is placed on the processing element corresponding to the flipping plate. Through intelligent control, the processing time is rationally planned. The clamping vibration motor corresponding to the middle of the flipping plate can eliminate some of the stress generated during pressure plate processing, making full use of the processing gap. In conjunction with the discharge vibration motor, the stress generated during subsequent processing is eliminated. The overall processing efficiency is high, and the product quality is also higher.

[0027] After the top and bottom surfaces of the pressure plate are machined, the clamping vibration motor corresponding to the fixed frame is started. The clamping vibration motor drives the clamped pressure plate to vibrate. Under the action of vibration, most of the cutting fluid remaining on the surface of the pressure plate can be separated from the pressure plate. When drying the pressure plate in the subsequent process, there is less cutting fluid remaining on the surface of the pressure plate, which speeds up the drying speed of the pressure plate and improves the overall production efficiency of the pressure plate.

[0028] During cutting, cutting fluid is sprayed from nozzles connected to the upper and lower gooseneck tubes. The sprayed cutting fluid washes the top and bottom surfaces of the pressure plate. Driven by the connection between the oscillating gear and the arc rack, the rotating frame and the ring box rotate back and forth through the oscillating motor. The cutting fluid sprayed from the nozzles can fully cover the top and bottom surfaces of the pressure plate, washing away the debris generated during cutting, resulting in better cleaning and improved product quality.

[0029] 2. Equipped with a finished product discharge assembly, the pneumatic gripper places the pressure plate on top of the four nearest support plates. Then, the stacking electric push rod descends by the thickness of one pressure plate. After the next pressure plate is processed, the pneumatic gripper stacks the next pressure plate on top of the original pressure plate, and repeats the process. Under the limit guidance of the guide rod, the processed pressure plates are neatly stacked, which facilitates the subsequent handling of the pressure plates by the robotic arm. When the pressure plates on the top of an assembly plate are stacked, the discharge motor drives the rotary table to rotate 90 degrees, resulting in high production continuity.

[0030] During the stacking of pressure plates, the corresponding heating wire and air pump operate. The air pump supplies air into the heating tank. After being heated by the heating wire, the air enters the rotating air pipe and is finally ejected from the air jet. The rotating air pipe is driven by the drive motor to rotate. The hot air ejected from the air jet blows on the surface of the pressure plate, drying the pressure plate and improving product quality. During the drying process of the pressure plate, the discharge vibration motor also operates at the same time, using vibration to eliminate the stress generated during processing, further improving product quality.

[0031] In summary, the inner and outer diameter electric actuators in the pressure plate processing assembly can clamp and fix pressure plates of various sizes. Combined with the upper and lower gooseneck tubes, the nozzle direction can be flexibly adjusted according to the pressure plate size, enabling the processing of pressure plates of various sizes. In the finished product discharge assembly, adjusting the electric actuator drives the adjusting slider and stacking electric actuator, and the guide electric actuator drives the guide rod, enabling the stacking, drying, and stress relief of pressure plates of various sizes. The combination of these two components is suitable for better intelligent manufacturing and has a wider range of applications. Attached Figure Description

[0061] The input terminals of the flipping motor 203, inner diameter electric push rod 207, pressure sensor 208, outer diameter electric push rod 211, clamping vibration motor 213, infusion pump 222, swing motor 225, transverse electric slide rail 233, lifting electric push rod 234, longitudinal electric slide rail 235, electric cutting blade 236, suspension electric slide rail 237, discharge motor 302, guide electric push rod 306, adjusting electric push rod 310, palletizing electric push rod 311, discharge vibration motor 313, driven gear 317, drive motor 319, heating wire 321, and air pump 322 are electrically connected to the external power supply output terminal through the controller. The controller can control each electrical component, enabling the device to achieve intelligent automatic control.

[0062] The working principle and usage process of this invention are as follows: First, the pressure plate is placed on top of the conveyor belt 240. The conveyor belt 240 moves the pressure plate to the suspended electric slide rail 237. The suspended electric slide rail 237 drives the pneumatic gripper 239 to move to the top of the pressure plate. The lifting cylinder 238 drives the pneumatic gripper 239 to descend, clamping and fixing the pressure plate on top of the conveyor belt 240. The suspended electric slide rail 237 drives the clamped pressure plate to move to the top of the tilting plate 202. Subsequently, the lifting cylinder 238 drives the pressure plate to descend. When the pressure plate descends to the middle of the inner diameter clamping plate 209 and the outer diameter clamping plate 214, the corresponding inner diameter electric push rod 207 and outer diameter electric push rod 211 in the middle of the tilting plate 202 are activated. The inner diameter clamping plate 209 and the outer diameter clamping plate 214 fix the pressure plate. The pressure sensor 208 feeds back the pressure data to the controller, ensuring that the pressure plate can be stably fixed while avoiding excessive pressure that could damage the pressure plate.

[0063] After the pressure plate is fixed, the transverse electric slide rail 233, the lifting electric push rod 234, and the longitudinal electric slide rail 235 on one side of the tilting plate 202 are activated. These three components work together, and the electric cutting tool 236 cuts one side of the pressure plate. Simultaneously, a fluid pump 222 corresponding to the tilting plate 202 is activated. The cutting fluid inside the cutting fluid tank 221 flows through the corresponding fluid hose 223 and fluid connector 220 into the annular box 216 at the bottom of the tilting plate 202. Subsequently, the cutting fluid is sprayed from the nozzle 219 connected to the upper gooseneck tube 218 and the lower gooseneck tube 217. The sprayed cutting fluid washes the top and bottom surfaces of the pressure plate, cutting the cutting fluid... The generated debris is washed away to prevent it from scratching the pressure plate and improve product quality. At the same time, the swing motor 225 starts. Driven by the swing gear 226 and the arc rack 224, the swing motor 225 drives the rotating frame 215 and the ring box 216 to rotate back and forth, which in turn drives the nozzle 219 to swing back and forth. This allows the cutting fluid sprayed from the nozzle 219 to fully cover the top and bottom surfaces of the pressure plate, resulting in better cleaning. Under the action of gravity, the cutting fluid generated during cleaning flows through the connecting port 205 and the isolation ring 228 into the drain hopper 231, and finally into the collection tank 232 for subsequent recycling.

[0064] After one side of the pressure plate is processed, the flipping motor 203 drives the flipping plate 202 to rotate. The flipping plate 202 rotates towards the top of the fixed frame 204. When the flipping plate 202 moves directly above the fixed frame 204, the pressure plate also moves to the middle of the inner diameter clamping plate 209 and the outer diameter clamping plate 214 in the middle of the fixed frame 204. Then, the inner diameter electric push rod 207 and the outer diameter electric push rod 211 in the middle of the fixed frame 204 are activated to fix the pressure plate. Then, the inner diameter electric push rod 207 and the outer diameter electric push rod 211 in the middle of the flipping plate 202 are activated, and the inner diameter clamping plate 209 and the outer diameter clamping plate 214 in the middle of the flipping plate 202 are disengaged from the pressure plate. After disengagement, the flipping motor 203 drives the flipping plate 202 to return to its original position.

[0065] Repeat the above processing steps for one side of the pressure plate. Then, the processing element corresponding to the fixing frame 204 can process the other side of the pressure plate. After the top and bottom surfaces of the pressure plate are processed, the clamping vibration motor 213 corresponding to the fixing frame 204 is started. The clamping vibration motor 213 drives the clamped pressure plate to vibrate. Under the action of vibration, most of the cutting fluid remaining on the surface of the pressure plate can be separated from the pressure plate. When drying the pressure plate in the subsequent process, there is less cutting fluid remaining on the surface of the pressure plate, which speeds up the drying speed of the pressure plate and improves the overall production efficiency of the pressure plate.

[0066] The inner diameter electric actuator 207 and the outer diameter electric actuator 211 work together to clamp and fix pressure plates of various sizes. With the upper gooseneck tube 218 and the lower gooseneck tube 217, the direction of the nozzle 219 can be flexibly adjusted according to the size of the pressure plate. The device can process pressure plates of various sizes and has a wide range of applications.

[0067] Subsequently, the clamping vibration motor 213 stops running, and the suspended electric slide rail 237, lifting cylinder 238, and pneumatic gripper 239 operate. The pneumatic gripper 239 moves to the pressure plate corresponding to the top of the fixed frame 204 and fixes the pressure plate after cutting. The inner diameter clamping plate 209 and outer diameter clamping plate 214 corresponding to the fixed frame 204 disengage from the pressure plate. The pneumatic gripper 239 places the pressure plate on top of the four nearest support plates 314. Then, the stacking electric push rod 311 descends by the thickness of one pressure plate. After the next pressure plate is processed, the pneumatic gripper 239 stacks the next pressure plate on top of the original pressure plate. The above steps are repeated. Under the limiting guidance of the guide rod 307, the processed pressure plates are neatly stacked to facilitate the subsequent handling of the pressure plates by the handling robot arm. When the pressure plates on the top of an assembly plate 304 are stacked, the discharge motor 302 drives the rotating disk 301 to rotate 90 degrees to ensure the continuity of processing.

[0068] During the stacking of pressure plates, the corresponding heating wire 321 and air pump 322 operate. The air pump 322 supplies air into the heating tank 320. After being heated by the heating wire 321, the air enters the rotating air pipe 315 and is finally ejected from the air jet hole 316. At the same time, the drive motor 319 drives the rotating air pipe 315 to rotate. The hot air ejected from the air jet hole 316 blows on the surface of the pressure plate, drying the pressure plate and improving product quality. During the drying process of the pressure plate, the discharge vibration motor 313 also operates at the same time, using vibration to eliminate the stress generated during processing and further improve product quality.

[0069] When the size of the pressure plate changes, the adjusting slider 309 and the stacking electric push rod 311 are moved by adjusting the electric push rod 310, and the guide electric push rod 306 moves the guide rod 307. The device can stack, dry and relieve stress on pressure plates of various sizes, and has a wider range of applications.

[0070] When the processing element corresponding to the fixed frame 204 processes the other side of the pressure plate, the suspended electric slide rail 237 drives the pneumatic gripper 239 back to the top of the conveyor belt 240, and transports the pressure plate conveyed by the conveyor belt 240 to the processing element corresponding to the flip plate 202 for processing, ensuring the continuity of pressure plate processing. When processing the pressure plate, the side of the pressure plate with a longer processing time is placed on the processing element corresponding to the fixed frame 204 for processing, and the side of the pressure plate with a shorter processing time is placed on the processing element corresponding to the flip plate 202 for processing. When the processing element corresponding to the fixed frame 204 processes the other side of the pressure plate, the pressure plate corresponding to the flip plate 202 has been processed. At this time, the clamping vibration motor 213 corresponding to the middle of the flip plate 202 drives the pressure plate to vibrate. By utilizing the processing gap, the vibration eliminates part of the stress generated during the processing of the pressure plate, making full use of the processing gap. In conjunction with the discharge vibration motor 313 to eliminate processing stress, the production continuity is high, the overall processing efficiency is high, and the product quality is also higher.
