Description

Technical Field

[0001] The present invention belongs to the technical field of rail transit train component maintenance, and more specifically, relates to an automated disassembly device and method for wheel-mounted brake discs. Background Art

[0002] With the rapid development of high-speed rail, EMUs, as core equipment for modern rail transit, are crucial for their safe and stable operation. The wheel-mounted brake discs on EMUs, as critical safety components, are directly related to the train's braking performance and driving safety. Therefore, regular inspection, maintenance, and, when necessary, efficient disassembly of these discs are essential to ensuring the safe operation of EMUs. In EMU maintenance workshops, disassembly of wheel-mounted brake discs is a frequent and critical operation, and factors such as operational efficiency, quality, and the working environment have a profound impact on the EMU's maintenance progress and overall operational efficiency. At present, the disassembly of EMU wheel-mounted brake discs in EMU maintenance workshops mainly relies on manual force using mechanical wrenches, which is labor-intensive. Since the wheels are old, the surface of the workpiece is covered with iron filings and impurities, and the site lacks the necessary dust collection and decontamination facilities, resulting in a poor working environment. The workpiece numbers and models are recorded manually, and the operation process lacks data traceability. Some brake discs with severe rust on the edges require manual hand-held grinders to grind the outer circle because the part numbers cannot be seen, causing iron filings to fly everywhere and a poor working environment for workers. The manually removed brake disc fixing bolts, nuts, and locating pins need to be picked up manually and cannot be automatically recycled. Due to the large number, the workload is high. Summary of the Invention

[0009] Furthermore, the hollow wheel cake turning machine includes a fixed frame, a turning mechanism connected to the upper part of the fixed frame, hollow wheel cake supporting structures fixed on both sides of the upper surface of the turning mechanism, a wheel cake horizontal transfer mechanism installed in the middle, and fixed mechanisms connected to both sides of the hollow wheel cake supporting structure.

[0010] Furthermore, the automatic recovery mechanism for bolts and nuts includes a support frame with sliding rails on both sides, a horizontal feeding mechanism with sliding rails on the top, a receiving tray slidingly connected to the sliding rails of the horizontal feeding mechanism, and a brake disc bottom bolt anti-reaction force and anti-rotation mechanism with one end connected to the receiving tray and the other end slidingly connected to the sliding rails on both sides of the support frame.

[0011] Furthermore, the wheel cake 180° flipping mechanism includes a gantry truss mechanism, a vertical bidirectional slide rail is provided on the column of the gantry truss mechanism, a connecting plate is slidably connected thereon, a wheel cake rotation mechanism is installed on the connecting plate, and one end of the wheel cake rotation mechanism is fixedly connected to a wheel cake fork positioning mechanism.

[0012] Furthermore, the brake disc grinding conveyor line includes a brake disc dust removal room, an overhead brake disc conveyor line passing through the inside of the brake disc dust removal room, a brake disc grinder installed in the middle of the brake disc conveyor line and inside the brake disc dust removal room, and a brake disc docking and flipping unloading mechanism docked and installed at the end of the brake disc conveyor line.

[0013] Furthermore, the brake disc grinder includes a machine base, a fourth vertical lifting platform is installed on the machine base, a brake disc rotating mechanism and a grinding head moving mechanism are installed on the fourth vertical lifting platform, a brake disc clamping and positioning mechanism for fixing the brake disc is installed on the upper part of the brake disc rotating mechanism, and a grinding head rotating mechanism is fixedly installed on the side of the grinding head moving mechanism.

[0015] According to another aspect of the present invention, the present invention provides an automated disassembly method for a wheel-mounted brake disc, comprising the following specific steps:

[0016] S100: After the workpiece is loaded by the hollow wheel turning machine, it is turned 90 degrees, and the workpiece is converted from a vertical posture to a horizontal posture. The wheel horizontal transfer mechanism transports the workpiece to the wheel positioning mechanism position in the workpiece positioning area. The wheel positioning mechanism extends a V-shaped block to clamp the outer circle of the workpiece;

[0017] S200: The wheel cake transfer vehicle moves to the bottom of the wheel cake positioning mechanism, and after jacking, it clamps the workpiece through the first center positioning clamping mechanism and the pneumatic three-jaw positioning chuck. At the same time, the V-block of the wheel cake positioning mechanism is retracted, and the wheel cake transfer vehicle transports the workpiece to the bottom of the brake disc disassembly machine at the brake disc disassembly position. The workpiece is clamped by the workpiece clamping mechanism at the top of the brake disc disassembly position, and the wheel cake transfer vehicle returns to the workpiece cache position; then, the hollow wheel cake turning machine rotates 90 degrees in the opposite direction and returns to the posture for loading;

[0018] S300: The automatic bolt and nut recovery mechanism retracts the receiving tray to directly below the workpiece to prepare for receiving the material. The loosening mechanism of the dual-axis brake disc dismantling machine descends to loosen the brake disc nuts. The nut adsorption mechanism attracts the nuts with magnets, and the automatic nut ejection recovery mechanism ejects the nuts under the magnets into the nut recovery pipe to recover the nuts on the top of the brake disc. The bottom bolts are received by the receiving tray and automatically fall into the recovery box, realizing automatic bolt recovery.

[0019] S400: After the brake disc bolts are disassembled, the bolts and nuts are automatically retracted by the brake disc disassembly machine. The disc-to-cake separation and transfer vehicle moves to the bottom of the brake disc disassembly machine, locates and grasps the workpiece, and lifts and transfers it to the disc-to-cake separation station.

[0020] S500: At the disc-cake separation station, the disc-cake separation transfer vehicle clamps the wheel cake via the first center positioning clamping mechanism. The brake disc automatic grabbing and lifting mechanism then moves to directly above the workpiece, grabs the brake disc on top of the workpiece, and places it on the brake disc grinding conveyor line, entering the brake disc automatic grinding process and unloading.

[0021] S600: The wheel cake separation and transfer vehicle continues to lift the middle wheel cake and the brake disc below. The hollow brake disc three-claw positioning and clamping mechanism clamps the brake disc below the wheel cake and then pulls it down, still together with the wheel cake separation and transfer vehicle. The middle wheel cake is transported to the wheel cake connection conveyor line and continues to flow backward. It passes through the wheel cake transfer and reversing mechanism, the wheel cake 180° flipping mechanism and the wheel cake buffer line in sequence to enter the next process.

[0022] S700: After the disc-to-cake separation transfer vehicle transports the lower brake disc to the disc-to-cake separation station, the lifting clamp is released, and the automatic brake disc grabbing and lifting mechanism moves to directly above the workpiece, transferring the lower brake disc to the brake disc grinding conveyor line, entering the brake disc automatic grinding process and unloading, realizing the automatic disassembly, separation, grinding, transportation and nut and bolt recovery of the disc.

[0023] In general, the above technical solutions conceived by the present invention can achieve the following beneficial effects compared with the prior art:

[0024] 1. The present invention relates to an automated disassembly equipment for wheel-mounted brake discs. The equipment loads the workpiece through a hollow wheel cake turning machine of a loading and automatic disassembly line, loosens the brake disc nuts and bolts through a brake disc disassembly machine, and classifies and recovers the nuts and bolts through an automatic nut recovery mechanism. After the nuts and bolts are removed, the wheel-mounted brake disc is grabbed by a disc cake separation and transfer vehicle in cooperation with an automatic brake disc grabbing and lifting mechanism, and transported to a brake disc grinding conveyor line for grinding and unloading the brake disc. The wheel cake is then separated by a wheel cake connecting conveyor line, and the wheel cake is transported backward for unloading, completing the operations of transporting the wheel-mounted brake disc, removing bolts, separating the wheel disc, grinding, and conveying, thereby realizing fully automatic flow operation, saving labor resources, and reducing the operation time from the original 15 minutes for manual disassembly to 5 minutes for each, thereby improving the efficiency of maintenance operations.

[0025] 2. The automated disassembly equipment for wheel-mounted brake discs of the present invention realizes the precise positioning of the center hole of the wheel cake and the fixing bolt hole of the brake disc by designing mechanical positioning mechanisms such as a center positioning clamping mechanism and a starting three-claw mechanism. Compared with the existing technology, it eliminates the steps of visual camera photography, recognition calculation and image analysis, thus saving operation time and improving work efficiency.

[0026] 3. The automated disassembly equipment for wheel-mounted brake discs of the present invention is provided with an operation control system. By introducing information technology, the disadvantages of manual recording of workpiece numbers in the past, which resulted in loss of operation data and inability to trace operation process data, are eliminated. Data interconnection of various mechanisms and modules is achieved, and digital automatic operation and data traceability of the entire process are realized. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] Example 1

[0049] like Figure 1As shown, an embodiment of the present invention provides an automated disassembly equipment for wheel-mounted brake discs, including a loading and automatic disassembly line 1, a wheel cake connecting conveyor line 2, a wheel cake transfer and reversing mechanism 3, a wheel cake 180° flipping mechanism 4, a wheel cake buffer line 5, a brake disc grinding conveyor line 6, and a brake disc automatic grabbing and lifting mechanism 7. The loading and automatic disassembly line 1 serves as a starting station and is responsible for the initial loading and disassembly of the wheel-mounted brake disc; the wheel cake connecting conveyor line 2 is connected to the end of the loading and automatic disassembly line 1 by fastening screws, receives the disassembled wheel cakes and conveys them to the wheel cake transfer and reversing mechanism 3 docked and installed at the end of the wheel cake connecting conveyor line 2, completing the wheel The direction of the cake is adjusted, and the 180-degree wheel cake flipping mechanism 4 is installed at the end of the wheel cake transfer and reversing mechanism 3, which continues to receive the wheel cake and completes the 180° flip. The flipped wheel cake is cached by the wheel cake cache line 5 installed with it, and the loading and automatic disassembly line 1 includes a disc-cake separation position 145, and the brake disc grinding conveyor line 6 is installed corresponding to the disc-cake separation position 145. The brake disc automatic grabbing and lifting mechanism 7 is connected across the disc-cake separation position 145 and the brake disc grinding conveyor line 6, grabs the brake disc and transports it to the brake disc grinding conveyor line 6, and the brake disc grinding conveyor line 6 grinds the disassembled brake disc. Each mechanism is fixed to the ground after being leveled by adjustable anchor bolts to ensure the overall stability of the equipment. Through the coordinated operation of each mechanism, the flow operation of wheel cake brake discs from transportation, bolt removal, wheel disc disassembly, grinding and conveying operations is realized. Among them,

[0050] like Figure 2 As shown, the loading and automatic disassembly line 1 includes a hollow wheel cake turning machine 11, a wheel cake positioning mechanism 12, a wheel cake transfer vehicle 13, a ground rail conveyor line 14, a brake disc disassembly machine 15, a disc cake separation transfer vehicle 16, and a bolt and nut automatic recovery mechanism 17.

[0051] like Figure 3As shown, the hollow wheel cake turning machine 11 is arranged at the workpiece starting position at one end of the ground rail conveyor line 14, and includes a fixed frame 111, a turning mechanism 112, a fixing mechanism 113, a hollow wheel cake supporting structure 114 and a wheel cake horizontal transfer mechanism 115. The fixed frame 111 serves as the main support, and the turning mechanism 112 is hingedly installed on the upper part. The turning mechanism 112 can be turned and switched between a 0° vertical posture and a 90° horizontal posture. The hollow wheel cake supporting structure 114 is fixed on both sides of the upper surface, and the wheel cake horizontal transfer mechanism 115 is installed in the middle. The fixing mechanism 113 is installed on both sides of the hollow wheel cake supporting structure 114. When loading is required, the flipping mechanism 112 turns to a 0° vertical posture, loads the material onto the hollow wheel cake support structure 114 and fixes the wheel-mounted brake disc through the fixing mechanism 113, then the flipping mechanism 112 flips 90° to a horizontal posture, and the wheel cake horizontal transfer mechanism 115 transports the workpiece to the center position of the wheel cake positioning mechanism 12 to enter the next process.

[0052] like Figure 4 As shown, the ground rail conveyor line 14 includes a bottom rail 141, a workpiece positioning area 142, a workpiece cache position 143, a brake disc disassembly position 144 and a disc-cake separation position 145. The bottom rail 141 is provided with a linear slide rail and a linear rack. The wheel-cake positioning mechanism 12 is installed on the top of the workpiece positioning area 142 for positioning the outer circle of the wheel cake. The top of the brake disc disassembly position 144 is provided with a workpiece clamping mechanism for clamping the workpiece.

[0053] The wheel cake positioning mechanism 12 is arranged on the inner side of the top of the workpiece positioning area 142 of the ground rail conveyor line 14 and is V-shaped. It cooperates with the hollow wheel cake turning machine 11. When the hollow wheel cake turning machine 11 transports the workpiece to the center of the workpiece positioning area 142, the wheel cake positioning mechanism 12 is extended by the drive of the cylinder to clamp the workpiece in position.

[0054] like Figure 5As shown, the wheel cake transfer vehicle 13 includes a first slide rail driving mechanism 131, a first vertical lifting mechanism 132, a first center positioning clamping mechanism 133, a pneumatic brake mechanism 134 and a bolt hole circumferential positioning mechanism 135. The bottom of the wheel cake transfer vehicle 13 is engaged with the bottom rail 141 of the track conveying line 14 through a linear slide rail and a gear rack mechanism. The first slide rail driving mechanism 131 drives the vehicle body to move on the track conveying line 14. The vertical lifting mechanism 132 is set under the vehicle body. Through the elevator, guide column lifting platform and servo The motor realizes the vertical lifting of the workpiece, and the guide column lifting platform is provided with the first center positioning clamping mechanism 133 and the pneumatic three-grip positioning chuck. The center hole of the workpiece is positioned and clamped by the first center positioning clamping mechanism 133, the pneumatic three-grip positioning chuck and the positioning boss. The pneumatic brake mechanism 134 is installed on the side of the first center positioning clamping mechanism 133 to realize the brake positioning of the workpiece, and the bolt hole circumferential positioning mechanism 135 is provided at a 45° inclination position on the guide column lifting platform table to realize the circumferential positioning of the brake disc fastening bolts.

[0055] like Figure 6 As shown, the brake disc disassembly machine 15 is arranged on the side of the brake disc disassembly position 144, including a frame 151, a vertical screw slide 152, a vertical screw slide drive mechanism 157 and a disassembly head, and the disassembly head includes a disassembly head horizontal rotation mechanism 153, a dual-axis brake disc disassembly machine loosening mechanism 154, a nut adsorption mechanism 155, and a nut automatic pop-up recovery mechanism 156. The lower part of the frame 151 as an overall supporting structure is set as an open space for cooperating with the track conveyor line 14 to install the bolt and nut automatic recovery mechanism 17, and the upper part facing the track conveyor line 14 is rigidly fixed with two vertical screw slides 152. An L-shaped fixed plate is slidably connected thereon and serves as a bearing base for the disassembling head. The upper end of the disassembling head is connected to the top plate of the L-shaped fixed plate, and the side is fixed to the side plate of the L-shaped fixed plate through the disassembling head horizontal rotation mechanism 153. The disassembling head is driven to move up and down along the vertical screw rail by the vertical screw rail driving mechanism 157. The disassembling head is driven to rotate horizontally by the rotation of the disassembling head horizontal rotation mechanism 153. The disassembling head is also provided with the dual-axis brake disc disassembling machine loosening mechanism 154 for loosening the workpiece nut, the nut adsorption mechanism 155 for adsorbing the loosened nut, and the nut automatic ejection recovery mechanism 156 for ejecting the adsorbed nut into a recovery pipe.

[0056] When the wheel cake transfer vehicle 13 transports the workpiece to the bottom of the disassembly head and is clamped by the workpiece clamping mechanism of the brake disc disassembly position 144 on the track conveyor line 14, the disassembly head moves down, and the double-axis brake disc disassembly machine loosens the mechanism 154 to loosen the fixed nuts on the brake disc; then the disassembly head horizontal rotation mechanism 153 rotates a fixed angle to continue tightening and loosening the next group of nuts. At the same time, the nut adsorption mechanism 155 aligns with the position of the nuts loosened in the previous process to adsorb the nuts. When the second group of nuts is loosened and the entire disassembly head is lifted, the nuts automatically pop out of the recovery mechanism 156. The push rod unloading mechanism inside the recovery mechanism ejects the nuts below the nut adsorption mechanism 155 into the nut recovery pipe, completing the automatic recovery of the loosened nuts, and the cycle is repeated.

[0057] like Figure 7 As shown, the pancake separation transfer vehicle 16 includes a second slide rail drive mechanism 161, a second vertical lifting mechanism 162, a second center positioning clamping mechanism 163, and a hollow brake disc three-claw positioning and clamping mechanism 164. The bottom of the pancake separation transfer vehicle 16 is engaged with the bottom track 141 of the track conveying line 14 through a linear slide rail and a gear rack mechanism. The second slide rail drive mechanism 161 drives the vehicle body to move on the track conveying line 14. The second vertical lifting mechanism 162 is set under the vehicle body, and the vehicle body is lifted and lowered by the elevator and guide column. The platform and the servo motor realize the vertical lifting of the workpiece. The guide column lifting platform is provided with the second center positioning clamping mechanism 163, the pneumatic three-grip positioning chuck and the hollow brake disc three-claw positioning and the clamping mechanism 164. The second center positioning clamping mechanism 163, the pneumatic three-grip positioning chuck and the positioning boss are used to realize the positioning and clamping of the center hole of the workpiece. The positioning and clamping of the brake disc under the workpiece are realized through the hollow brake disc three-claw positioning and the clamping mechanism 164, and the disassembly of the lower brake disc is realized in cooperation with the second vertical lifting mechanism 162.

[0058] like Figure 8 As shown, the automatic bolt and nut recovery mechanism 17 is located in the lower internal space of the brake disc disassembly machine 15 and is usually in a retracted state. It includes a support frame, a third vertical lifting mechanism 171, a horizontal feeding mechanism 172, a brake disc bottom bolt anti-reaction force and anti-rotation mechanism 173 and a receiving tray 174. Slide rails are provided on both sides of the support frame and the surface of the horizontal feeding mechanism 172. One end of the brake disc bottom bolt anti-reaction force and anti-rotation mechanism 173 is slidably connected to the slide rails on both sides of the support frame, and the other end is connected to the end of the receiving tray 174. The slightly inclined bottom of the receiving tray 174 is slidably connected to the slide rail of the horizontal feeding mechanism 172. The two form a whole and are extended and retracted through the slide rail at the bottom of the horizontal feeding mechanism 172 and the slide rails on both sides of the support frame.

[0059] After the wheel cake transfer car 13 transports the workpiece to the brake disc disassembly position 144 of the track conveyor line 14 and when the transfer car leaves, the receiving tray 174 extends out from the cabinet of the brake disc disassembly machine 15 frame 151 through the horizontal feeding mechanism 172, and then the third vertical lifting mechanism 171 rises and contacts the bolt head at the bottom of the workpiece through the anti-reaction force and anti-rotation mechanism 173 of the bolt at the bottom of the brake disc. When the brake disc disassembly machine 13 has removed all the nuts, the third vertical lifting mechanism 171 descends, and all the bolt heads fall to the receiving tray 174 under the influence of gravity and slide down into the waste recycling box; finally, the receiving tray 174 is retracted through the horizontal feeding mechanism 172, and the entire mechanism returns to the lower interior of the brake disc disassembly machine 15 frame 151. At this time, the wheel cake transfer car 13 can pass through the track below the brake disc disassembly position 144, and transport the brake disc and wheel cake workpiece whose bolts have been disassembled to the next process.

[0060] The bottom of the wheel cake connecting conveyor line 2 is connected to the wheel loading and brake disc automatic disassembly line 1, and the middle is an open space for parking the disc cake separation transfer vehicle 16. Two rows of cantilevered drive rollers are designed on both sides. After the disc cake separation transfer vehicle 16 transports the workpiece to the middle position of the wheel cake connecting conveyor line 2, it cooperates with the disc cake separation transfer vehicle 16 to separate the wheel cake from the lower brake disc.

[0061] The wheel cake transfer and reversing mechanism 3 includes a base, a horizontal turntable, a wheel cake positioning mechanism and a wheel cake driving mechanism. The horizontal turntable is rotated to achieve smooth connection with the wheel cake connecting conveyor line 2 and the wheel cake 180° flipping mechanism 4. Specifically, the wheel cake on the wheel cake connecting conveyor line 2 is connected by the wheel cake transfer and reversing mechanism 3. After the wheel cake is transferred to this mechanism, the horizontal turntable rotates 90°, the wheel cake driving mechanism reverses and aligns the wheel cake with the wheel cake 180° flipping mechanism 4 and connects with it. The wheel cake is transferred to the wheel cake 180° flipping mechanism 4, and this mechanism rotates 90° in the opposite direction and returns to its original position, ready for the next connection.

[0062] like Figure 9As shown, the wheel cake 180° flipping mechanism 4 is used for the workpiece posture with the wheel cake rim facing downwards. When the workpiece passes through this mechanism, the wheel cake is flipped 180° so that the wheel cake rim faces upwards, which is convenient for transporting to the wheel cake buffer line 5 for robot lifting and clamping. It includes a wheel cake conveyor line 41, a gantry truss mechanism 42, a two-way slide rail 43, a wheel cake fork positioning mechanism 44 and a wheel cake rotating mechanism 45. The wheel cake conveyor line 41 spans over the two long sides of the bottom of the gantry truss mechanism 42, and the vertical A straight bidirectional slide rail 43 has two connecting plates slidingly connected thereon, and the wheel cake rotating mechanism 45 is fixed on the connecting plate, one end of which is equipped with the wheel cake fork positioning mechanism 44. This mechanism receives the wheel cake from the wheel cake transfer and reversing mechanism 3, and transports it to the center position by the wheel cake conveyor line 41. The wheel cake fork positioning mechanism 44 slides down along the vertical bidirectional slide rail 43 to clamp the wheel cake for positioning, and after flipping 180° under the action of the wheel cake rotating mechanism 45, it continues to be transported by the wheel cake conveyor line 41 to the wheel cake cache line 5 for the next process.

[0063] like Figure 10 As shown, a roller structure is provided on the top of the wheel cake cache line 5, and a steel structure is provided around it. A plurality of rollers are driven to rotate by a chain mechanism to realize the transportation of the wheel cake delivered from the wheel cake 180° flipping mechanism 4; the inside of the roller is a steel structure and the outside is wrapped with polyurethane rubber. It is thin in the middle and thick at both ends, and is shaped like a dumbbell. The thin part in the middle is used to avoid the outer circular step surface of the center hole of the wheel cake, ensuring that the wheel cake is level and easy to pass.

[0064] like Figure 11-12 As shown, the brake disc grinding conveyor line 6 includes a brake disc conveyor line 61, a brake disc grinder 62, a brake disc dust removal room 63 and a brake disc connecting and flipping unloading mechanism 64. The brake disc conveyor line 61 adopts a belt type, with a group of belts on each side and an overhead structure in the middle for installing the brake disc grinder 62. The brake disc dust removal room 63 is sleeved on the outer periphery of the brake disc grinder 62. The bottom of the brake disc conveyor line 61 is a steel structure, which is driven by a servo motor and a synchronous belt, and runs smoothly and reliably. It passes through the inside of the brake disc dust removal room 63. The brake disc grinder 62 is arranged inside the brake disc dust removal room 63 and in the middle of the brake disc conveyor line 61. The brake disc connecting and flipping unloading mechanism 64 is arranged at the end of the brake disc conveyor line 61 to connect the polished brake disc. Among them,

[0065] like Figure 13As shown, the brake disc grinding machine 62 includes a machine base 621, a fourth vertical lifting platform 622, a brake disc rotating mechanism 623, a brake disc clamping and positioning mechanism 624, a grinding head rotating mechanism 625, and a grinding head moving mechanism 626. The fourth vertical lifting platform 622 is mounted on the machine base 621, and the brake disc rotating mechanism 623 and the grinding head moving mechanism 626 are mounted on the fourth vertical lifting platform 622. The brake disc clamping and positioning mechanism 624 is mounted on the top of the brake disc rotating mechanism 623 to fix the brake disc. The grinding head rotating mechanism 625 is fixedly mounted on the side of the grinding head moving mechanism 626 to drive the grinding head to rotate and grind the brake disc.

[0066] After the brake disc workpiece is automatically grasped and lifted by the brake disc and placed on the brake disc conveyor line 61 by the brake disc automatic grasping and lifting mechanism 7, it is conveyed to the inside of the brake disc dust removal room 63. At this time, the fourth vertical lifting platform 622 rises, passes through the center hole of the brake disc and clamps it through the three-claw mechanism of the brake disc clamping and positioning mechanism 624, and rotates the brake disc through the lower brake disc rotating mechanism 623. The grinding head approaches the edge of the brake disc through the grinding head moving mechanism 626. The grinding head rotates under the power of the grinding head rotating mechanism 625 to perform the grinding operation on the outer circle of the brake disc. After the operation is completed, the grinding head stops, the grinding head moving mechanism 626 retreats, the fourth vertical lifting platform 622 descends, and the brake disc conveyor line 61 continues to operate to transport the brake disc to the brake disc connection flipping and unloading mechanism 64.

[0067] like Figure 14 As shown, the brake disc connection, turnover and unloading mechanism 64 includes a fixed frame 641, a rotating disc 642, a rotary drive mechanism 643, a brake disc positioning mechanism 644 and a brake disc transfer and rolling mechanism 645. The rotating disc 642 is mounted on top of the fixed frame 641 and is driven by the rotary drive mechanism 643 mounted in the middle of the fixed frame 641 to rotate 90 degrees. The brake disc transfer and rolling mechanism 645 is arranged on the top of the rotating disc 642, and the brake disc positioning mechanism 644 is mounted on the side. After the brake disc is polished, the brake disc connection, turnover and unloading mechanism 64 receives the brake disc workpiece from the brake disc conveyor line 61, transfers the workpiece to the rotating disc 642 via the brake disc transfer and rolling mechanism 645, positions the brake disc workpiece via the brake disc positioning mechanism 644, and rotates the brake disc workpiece 90 degrees via the rotary drive mechanism 643, making it easier for workers to lift and pack the entire workpiece for transportation to the next process.

[0068] like Figure 15As shown, the brake disc automatic grasping and lifting mechanism 7 is in the form of a gantry truss as a whole, including a column 71, a first connecting beam 72, a second connecting beam 73, a first sliding beam 74, a second sliding beam 75, and a pneumatic three-claw opening and closing mechanism 76. This mechanism is fixed to the ground through the four columns 71. The top of the column 71 is connected by the two first connecting beams 72 and the two second connecting beams 73. Slide rails are provided on the first connecting beam 72 and the second connecting beam 73. A first sliding beam 74 is vertically slidably connected to the top of the two second connecting beams 73. The side of the first sliding beam 74 is slidably connected to the second sliding beam 75 that can slide up and down. The first sliding beam 74 and the second sliding beam 75 are used to realize movement to any point within the coverage range of the gantry truss. The pneumatic three-claw opening and closing mechanism 76 is connected to the end of the second sliding beam 75. The brake disc fixing clamp is connected to each moving claw by a fastening screw for the brake disc grasping operation.

[0069] The device of the embodiment of the present invention also includes an operation control system, which connects the data of various mechanisms and modules, realizes digital management of the process, and records workpiece data to facilitate data tracing and query of later operation results.

[0070] Example 2, as Figure 16 As shown, an embodiment of the present invention provides an automated disassembly method for a wheel-mounted brake disc, comprising the following specific steps:

[0071] S100: The workpiece with a wheel-mounted brake disc is loaded by the hollow wheel-cup turning machine 11 and turned 90°, converting the workpiece from a vertical position to a horizontal position. The wheel-cup horizontal transfer mechanism 115 transports the workpiece to the wheel-cup positioning mechanism 12 in the workpiece positioning area 142; the wheel-cup positioning mechanism 12 extends a V-shaped block to clamp the outer circle of the workpiece, thereby achieving center positioning of the workpiece.

[0072] S200: The wheel cake transfer vehicle 13 moves to the bottom of the wheel cake positioning mechanism 12, the first vertical lifting mechanism 132 rises, the first center positioning clamping mechanism 133 is inserted into the center inner hole of the workpiece, the pneumatic three-claw mechanism opens to clamp the workpiece, the V-block of the wheel cake positioning mechanism 12 is retracted, and the wheel cake transfer vehicle 13 transports the workpiece to the bottom of the brake disc disassembly machine 15 at the brake disc disassembly position 144 (if the operation of the brake disc disassembly machine 15 is not completed, the wheel cake transfer vehicle 13 transports the workpiece to the workpiece cache position 143 for cache), the workpiece is clamped by the workpiece clamping mechanism at the top of the brake disc disassembly position 144, and the wheel cake transfer vehicle 13 returns to the workpiece cache position 143; then, the hollow wheel cake turning machine 11 rotates 90 degrees in the opposite direction and returns to the posture for loading;

[0073] S300: The automatic bolt and nut recovery mechanism 17 extends the receiving tray 174 to the bottom of the workpiece to prepare for receiving the material; the dual-axis brake disc dismantling machine loosening mechanism 154 descends to loosen the brake disc nuts; the nut adsorption mechanism 155 adsorbs the nuts through the magnet, and the nut automatic ejection recovery mechanism 156 inside it ejects the nuts under the magnet into the nut recovery pipe to achieve the recovery of the nuts on the top of the brake disc; the bottom bolts are received by the receiving tray 174 and automatically fall into the recovery box, achieving automatic recovery of the bolts;

[0074] S400: After the brake disc bolts are disassembled, the bolt and nut automatic recovery mechanism 17 below the brake disc disassembly machine retracts them; the disc-to-cake separation and transfer vehicle 16 moves to the bottom of the brake disc disassembly machine 15, inserts the middle three-claw telescopic mechanism of the pneumatic three-claw positioning chuck into the center hole of the workpiece, and lifts the workpiece and transfers it to the disc-to-cake separation station 145;

[0075] S500: At the disc-cake separation station 145, the disc-cake separation transfer vehicle 16 clamps the wheel cake via the first center positioning clamping mechanism 133. The brake disc automatic grabbing and lifting mechanism 7 moves to the top of the workpiece, grabs the top brake disc, and places it on the brake disc grinding conveyor line 6, entering the brake disc automatic grinding process.

[0076] S600: The wheel cake separation and transfer vehicle 16 continues to lift the middle wheel cake and the brake disc below. The hollow brake disc three-claw positioning and clamping mechanism 164 clamps the brake disc below the wheel cake and then pulls it down together with the wheel cake separation and transfer vehicle 16. The middle wheel cake is transported to the wheel cake connecting conveyor line 2 and continues to flow backward. It passes through the wheel cake transfer and reversing mechanism 3, the wheel cake 180° flipping mechanism 4 and the wheel cake buffer line 5 in sequence to enter the next process.

[0077] S700: The disc-to-cake separation transfer vehicle 16 transports the lower brake disc to the disc-to-cake separation station 145, lifts it, releases the clamping claws, and cooperates with the brake disc automatic gripping and lifting mechanism 7 to transfer the lower brake disc to the brake disc grinding conveyor line 6, and then flows into the next process;

[0078] S800: Repeat steps S100 to S800 to achieve automatic disassembly, separation, grinding, transportation and nut and bolt recovery of the plate.

[0079] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
