Description

Technical Field

[0001] This invention relates to the field of aluminum alloy forging processing technology, specifically a turning device for processing high-strength aluminum alloy forgings for aerospace applications. Background Technology

[0002] Aluminum alloy forgings refer to metal parts made from aluminum alloys through forging processes. The aerospace industry is highly sensitive to aircraft weight; lightweighting can reduce fuel consumption, increase payload capacity, and extend range. High-strength aluminum alloys possess high strength and low density, allowing for weight reduction in aircraft while meeting strength requirements. During machining, high-strength aluminum alloy forgings are cut using cutting tools to achieve precise dimensions and shapes. In the aerospace field, the dimensional accuracy requirements for parts are extremely high, and turning can meet these requirements.

[0003] In the existing technology, the cutting tools used in the turning equipment for machining high-strength aluminum alloy forgings for aerospace are generally bolted to the tool holder. When other cutting tools are needed, the bolts need to be unscrewed, a new tool needs to be replaced, and then the bolts need to be used again.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. In use, the present invention selects other cutting tools via a PLC controller. The PLC controller then activates a cylinder to pull the mounting block into the replacement box. Next, it controls a hydraulic rod to activate, pushing the top block upwards so that the top rod inserts into the cylindrical slot. Then, it activates two electric actuators to pull two triangular inserts into the inner groove. Driven by the hydraulic rod, the mounting block enters the rotating ring. The servo motor then activates, driving the rotating rod, connecting rod, and rotating ring to rotate intermittently. When the camera detects the target cutting tool, the servo motor shuts off, and the hydraulic rod activates again, pushing the top block through the arc-shaped hole upwards so that the top rod inserts into the cylindrical slot. This further pushes the mounting block into the connecting block. The two electric actuators are then activated again to push the triangular inserts into the triangular slot. The hydraulic rod then pulls the top block and top rod downwards to reset. Finally, the cylinder is activated to move the connecting block and mounting block onto the support plate, thus achieving automatic and rapid replacement of different cutting tools, saving manpower and time.

[0019] 2. When this invention is in use, the cylinder pushes the mounting block to move, and one end of each of the two fixing rods passes through the slide groove and enters the slot, abutting against the inner wall of the slot. The cylinder and fixing rods cooperate to firmly fix the mounting block, improving the stability of the mounting block and the cutting tool. This prevents the cutting tool from shaking when the mounting block shakes during subsequent cutting of the aluminum alloy forging, thus affecting the cutting accuracy. Then, the connecting block and the cutting tool both pass through the protective hole, and the inlet and outlet holes are protected by a protective cover to prevent the debris generated by the aluminum alloy forging during the cutting process from accidentally entering the replacement box through the inlet and outlet holes and affecting the normal operation of the equipment in the replacement box.

[0020] 3. When using this invention, one end of the aluminum alloy forging is clamped and fixed by the gripper. The drive motor is started by the operation button on the PLC controller, which drives the spindle to rotate, then drives the gripper to rotate, and further drives the aluminum alloy forging to rotate. At the same time, the feed mechanism is started, which drives the moving block to move inside the moving groove, drives the replacement component to move, and thus drives the cutting tool to move, so as to cut and process one end of the aluminum alloy forging.

A cylindrical block 228 is fixedly installed on the bottom of each of the four mounting blocks 221. Three cylindrical slots 229 are opened at the bottom of each of the four cylindrical blocks 228. An arc-shaped hole 226 is opened on the bottom surface inside the annular groove 217. A hydraulic rod 224 is fixedly installed on the bottom surface of the replacement box 201 near the rear surface wall. A top block 225 is fixedly installed on the top of the hydraulic rod 224, and three top rods 227 are fixedly installed on the top of the top block 225. A detection hole 210 is opened on the top of the replacement box 201 near the rear surface. A detection cover 204 is bolted to the top of the replacement box 201 near the detection hole 210. A camera 209 is fixedly installed on the top surface inside the detection cover 204. An inlet / outlet hole 215 is opened on the rear surface of the replacement box 201. A support plate 205 is fixedly installed on the rear surface of the replacement box 201 near the inlet / outlet hole 215. Two fixing rods 206 are fixedly installed on the rear surface of the replacement box 201 near the support plate 205. The inlet / outlet hole 215 is movably embedded inside. There are two support rods 211. A cylinder 212 is fixedly installed on the front wall near the top surface inside the replacement box 201. A connecting block 213 is fixedly installed on the output end of the cylinder 212. Support blocks 214 are fixedly installed on the top of the connecting block 213 near both sides. An embedded groove 231 is opened on both sides inside the connecting block 213. An electric push rod 232 is fixedly installed inside the two embedded grooves 231. A triangular insert 233 is fixedly installed at one end of each of the two electric push rods 232. One end of each of the two support rods 211 is fixedly installed on the top surface inside the replacement box 201. The outer surfaces of the two support rods 211 are movably embedded in the two support blocks 214. Triangular slots 222 are opened on both outer surfaces of the four mounting blocks 221. Both sides of the outer surface of block 221 near the bottom are provided with sliding grooves 223. Each side of the sliding grooves 223 has a slot 230. The top of the replacement box 201 has a movable cavity 202. A transparent protective cover 203 is movably embedded inside the movable cavity 202. The transparent protective cover 203 is rotatably connected to the replacement box 201 via a hinge. Four connecting rods 218 are fixedly installed on the outer surface of the annular track 216. One end of each of the four connecting rods 218 is fixedly installed inside the replacement box 201. The outer surface of the rotating rod 208 is movably embedded inside the annular track 216. The outer surfaces of the four cylindrical blocks 228 are movably embedded inside the annular groove 217. The bottoms of the four mounting blocks 221 are in contact with the top of the annular track 216.

[0034] In this embodiment, during use, the feeding mechanism 103, drive motor 110, servo motor 207, camera 209, cylinder 212, hydraulic rod 224, electric push rod 232, and PLC controller 108 are electrically connected. Opening the transparent protective cover 203 and starting the servo motor 207 causes the rotating rod 208 and four connecting rods 218 to rotate via the output of the servo motor 207, which in turn drives the four rotating rings 220 to rotate. After each 90-degree rotation of the rotating rings 220, the servo motor 207 pauses for a few seconds before resuming operation, causing the four rotating rings 220 to rotate intermittently. Simultaneously, the rotation of the four rotating rings 220 drives the four mounting blocks 221 to rotate on the top of the circular track 216. When the mounting blocks... When 221 is rotated to the movable cavity 202 and paused for a few seconds, the mounting block 221 is removed, thereby removing all four mounting blocks 221 from the replacement box 201. The operator installs different cutting tools into the four mounting blocks 221 one by one with bolts, and then puts the mounting blocks 221 with cutting tools into the rotating ring 220, so that the cylindrical block 228 is inserted into the annular groove 217, and the bottom of the four mounting blocks 221 is in contact with the top of the annular track 216. At this time, the four corners of the mounting blocks 221 near the bottom are in contact with the inner wall of the rotating ring 220. With the intermittent rotation of the rotating rod 208, the reinforcing rod 219 and the rotating ring 220, four mounting blocks 221 with different cutting tools are put in. When a specific cutting tool is needed, the user selects it via the operation button on the PLC controller 108 and activates the camera 209. The servo motor 207 drives four rotating rings 220 to rotate, which in turn rotates four mounting blocks 221 on which the cutting tools are mounted. When the mounting blocks 221 and the cutting tools rotate to below the detection hole 210, they pause for a few seconds. During this time, the camera 209 captures an image of the mounting blocks 221 and the cutting tools at that location and transmits the detected image information to the PLC controller 108 via an electrical signal. The PLC controller 108 has pre-stored images of the cutting tools to be used. The PLC controller 108 then identifies and compares the received image information to determine which cutting tool is required. When the cutting tool is in operation, the PLC controller 108 controls the servo motor 207 to shut down, and then controls the hydraulic rod 224 to start. The hydraulic rod 224 pushes the top block 225 and the push rod 227 through the arc-shaped hole 226 upwards, so that the top of the top block 225 contacts the bottom of the cylindrical block 228. The three push rods 227 are inserted into the three cylindrical slots 229. As the hydraulic rod 224 continues to push, it pushes the cylindrical block 228 out of the annular groove 217, so that the mounting block 221 enters the connecting block 213. Then the hydraulic rod 224 automatically pauses for a few seconds, and then controls the two electric actuators 232 to start, pushing the two triangular inserts 233 to move relative to each other and insert into the triangular slots 222 in the corresponding positions, thereby connecting the mounting block 221 and the connecting block 213 together.Then, hydraulic rod 224 resumes operation. At this time, hydraulic rod 224 pulls top block 225 and top rod 227 downward to reset. Next, control cylinder 212 starts, pushing connecting block 213 to move towards inlet / outlet hole 215, causing two support blocks 214 to slide on the outer surface of two support rods 211, further pushing mounting block 221 and cutting tool through inlet / outlet hole 215 and moving onto support plate 205. Meanwhile, cylindrical block 228 moves together to the inner recess of support plate 205. As mounting block 221 continues to move, one end of two fixed rods 206 gradually enters two sliding grooves 223, and then enters two retaining grooves 230. When cylinder 212 starts moving... When the device is closed, one end of each of the two fixing rods 206 is inserted into the two slots 230 and abuts against the inner wall of the slots 230. The cylinder 212 and the fixing rods 206 cooperate to firmly fix the mounting block 221, improving the stability of the mounting block 221 and the cutting tool. This prevents the cutting tool from shaking when the mounting block 221 is used to cut the aluminum alloy forging, thus affecting the cutting accuracy. After the cutting tool is fixed, the aluminum alloy forging can be cut using the cutting assembly 1. When it is necessary to change to another cutting tool, the PLC controller 108 selects another cutting tool. Then, the PLC controller 108 will restart the cylinder 212 and pull the mounting block 221. The mounting block 221 passes through the inlet / outlet hole 215 into the replacement box 201. When the cylinder 212 automatically closes, the control hydraulic rod 224 starts, pushing the top block 225 upward, causing the top rod 227 to re-insert into the cylindrical slot 229. Then, the two electric actuators 232 are activated, pulling the two triangular inserts 233 from inside the triangular slot 222 into the inner groove 231. At this time, the mounting block 221 loses its connection with the connecting block 213. Then, the hydraulic rod 224 moves downward, driving the mounting block 221 downward into the rotating ring 220, and the cylindrical block 228 enters the annular groove 217. When the top rod 227 resets, the servo motor 207 is activated, driving the rotating ring. 220 continues to rotate and, with the assistance of camera 209, detects the target cutting tool. Once the target cutting tool is detected, servo motor 207 shuts off again, and hydraulic rod 224 restarts, repeating the above operation process. This achieves automatic and rapid tool changing, eliminating the need for manual unscrewing of bolts, tool replacement, and retightening of bolts, saving manpower and time. This solves the problem of cumbersome and time-consuming processes in machining high-strength aluminum alloy forgings for aerospace applications, where tool replacement requires unscrewing bolts, removing the original tool, installing a new tool, and retightening the bolts—a process that affects processing progress and reduces production efficiency.

[0035] Example 2: Figures 1-5As shown, the assembly includes a cutting component 1 for machining aluminum alloy forgings. A replacement component 2 is mounted on the top of the cutting component 1 for quick tool changing. The cutting component 1 includes a frame 101, with a mounting plate 102 fixedly installed at the bottom. A feed mechanism 103 is located inside the mounting plate 102, and a moving block 104 is mounted on the top of the feed mechanism 103. A moving slot 105 is formed on the top of the frame 101, and the outer surface of the moving block 104 is movably embedded in the moving slot 105. A drive box 106 is bolted to one side of the top of the frame 101, and one side of the outer surface of the drive box 106 is bolted... The drive box 106 is equipped with an inspection door 107. Inside the drive box 106, a drive motor 110 is installed with screws. A spindle 111 is fixedly installed at the output end of the drive motor 110. A gripper 109 is provided at one end of the spindle 111. A mounting hole 113 is provided on the outer surface of the other side of the drive box 106. A bearing 112 is installed inside the mounting hole 113. The outer surface of the spindle 111 is fixedly installed inside the bearing 112. A PLC controller 108 is installed on the front surface of the drive box 106 with screws. The bottom of the replacement box 201 is fixedly installed on the top of the moving block 104. A protective cover 3 is fixedly installed on the rear surface of the replacement box 201. A protective hole 4 is provided on the rear surface of the protective cover 3.

[0036] In this embodiment, the feeding mechanism 103 is a mature existing technology, mainly composed of a motor, lead screw, limit rod, and movable block, as follows: Figure 3 As shown, the bottom of the moving block 104 is mounted on top of the movable block in the feed mechanism 103. After the appropriate cutting tool is replaced by the replacement assembly 2, one end of the aluminum alloy forging is clamped and fixed by the gripper 109. The drive motor 110 is started by the operation button on the PLC controller 108. The output end of the drive motor 110 drives the spindle 111 to rotate, which in turn drives the gripper 109 to rotate, further driving the aluminum alloy forging to rotate. At the same time, the feed mechanism 103 is started, driving the moving block 104 to move inside the moving groove 105, driving the replacement assembly 2 to move, thereby driving the cutting tool to move and cut one end of the aluminum alloy forging. After the replacement assembly 2 replaces the appropriate tool, both the connecting block 213 and the cutting tool pass through the protective hole 4. Figure 4 As shown, the protective cover 3 protects the inlet and outlet hole 215 to prevent the chips generated during the cutting process of the aluminum alloy forging from accidentally entering the replacement box 201 through the inlet and outlet hole 215 and affecting the normal operation of the equipment in the replacement box 201, thereby achieving the protective effect.

[0037] The overall mechanism works as follows: When a specific cutting tool is needed, the required tool is selected via the operation button on the PLC controller 108. The camera 209 is then activated, and the servo motor 207 drives the rotating rod 208, reinforcing rod 219, and four rotating rings 220 to rotate intermittently. This, in turn, causes the four mounting blocks 221, on which the cutting tools are mounted, to rotate intermittently. When the mounting blocks 221 and the cutting tools rotate to below the detection hole 210, the rotation pauses for a few seconds. At this time, the camera 209 captures an image of the mounting blocks 221 and the cutting tools at that location and transmits the detected image information to the PLC controller 108 via electrical signals for identification and comparison. If the captured cutting tool is the one required, the camera detects the error. The PLC controller 108 then controls the servo motor 207 to shut down, and then controls the hydraulic rod 224 to start. The hydraulic rod 224 pushes the top block 225 and the push rod 227 through the arc-shaped hole 226 upward, so that the top of the top block 225 contacts the bottom of the cylindrical block 228. The three push rods 227 are inserted into the three cylindrical slots 229. As the hydraulic rod 224 continues to push, it pushes the cylindrical block 228 out of the annular groove 217, so that the mounting block 221 enters the connecting block 213. Then the hydraulic rod 224 automatically pauses for a few seconds, and then controls the two electric actuators 232 to start, pushing the two triangular inserts 233 to move relative to each other and insert into the triangular slots 222 in the corresponding positions, thereby connecting the mounting block 221 and the connecting block 213 together. Then, the hydraulic rod 224 resumes operation. At this time, the hydraulic rod 224 pulls the top block 225 and the top rod 227 downward to reset. Next, the control cylinder 212 starts, pushing the connecting block 213 to move towards the inlet / outlet hole 215, causing the two support blocks 214 to slide on the outer surface of the two support rods 211, further pushing the mounting block 221 and the cutting tool through the inlet / outlet hole 215 and moving onto the support plate 205. Meanwhile, the cylindrical block 228 moves together to the inner recess of the support plate 205. As the mounting block 221 continues to move, it will pass through the protective hole 4, and the protective cover 3 will protect the inlet / outlet hole 215. One end of the two fixed rods 206 gradually enters the two sliding grooves 223, and then enters the two slots 230. When the cylinder 212... When automatically shutting off, one end of each of the two fixing rods 206 inserts into the two slots 230 and abuts against the inner wall of the slots 230. The cylinder 212 and the fixing rods 206 cooperate to firmly fix the mounting block 221, improving the stability of the mounting block 221 and the cutting tool. Then, the gripper 109 clamps and fixes one end of the aluminum alloy forging. The drive motor 110 is started by the operation button on the PLC controller 108, which drives the spindle 111 and the gripper 109 to rotate, further driving the aluminum alloy forging to rotate. At the same time, the feed mechanism 103 is started, driving the moving block 104 to move inside the moving groove 105, driving the replacement component 2 to move, thereby driving the cutting tool to move and cut one end of the aluminum alloy forging. When it is necessary to change to another cutting tool,The PLC controller 108 selects other cutting tools, then restarts the cylinder 212, pulling the mounting block 221 through the inlet / outlet hole 215 into the replacement box 201. When the cylinder 212 automatically closes, the hydraulic rod 224 is activated, pushing the top block 225 upward, causing the top rod 227 to re-insert into the cylindrical slot 229. Then, the two electric actuators 232 are activated, pulling the two triangular inserts 233 from inside the triangular slot 222 into the inner groove 231. At this point, the mounting block 221 and... When the connection between connecting blocks 213 is lost, the hydraulic rod 224 moves downward, causing the mounting block 221 to move downward into the rotating ring 220. The cylindrical block 228 enters the annular groove 217. When the push rod 227 resets, the servo motor 207 is activated, driving the rotating ring 220 to continue rotating. With the assistance of the camera 209, the target cutting tool is detected. Once the target cutting tool is detected, the servo motor 207 shuts off again, and the hydraulic rod 224 restarts, repeating the above operation process to achieve rapid replacement of different cutting tools.
