Description

Technical Field

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

[0002] With the rapid development of high-speed rail, the safe and stable operation of high-speed trains, as the core equipment of modern rail transit, is of paramount importance. The wheel-mounted brake discs of high-speed trains, as critical safety components, directly affect the braking performance and operational safety of the train. Therefore, regular inspection, maintenance, and, when necessary, efficient disassembly of the wheel-mounted brake discs are indispensable links in ensuring the safe operation of high-speed trains. In the high-speed train maintenance workshop, the disassembly of wheel-mounted brake discs is frequent and critical; its efficiency, quality, and working environment all have a profound impact on the maintenance progress and overall operational efficiency of the high-speed trains. Currently, in the EMU maintenance workshop, the disassembly of wheel-mounted brake discs for EMU trains mainly relies on manual labor using mechanical wrenches, which is labor-intensive. Because these are old wheels, the workpiece surface is covered with iron filings and impurities, and the site lacks necessary dust collection and cleaning facilities, resulting in a harsh working environment. Workpiece markings and models are manually recorded, lacking data traceability during the operation. Some brake discs with severely rusted edges require manual grinding of the outer circumference because the part markings are not visible, causing iron filings to fly everywhere and further complicating the workers' working conditions. Manually removed brake disc fixing bolts, nuts, and locating pins must be picked up manually as they cannot be automatically recycled, leading to a large workload due to the large quantity involved. Summary of the Invention

[0003] In view of the above-mentioned defects or improvement needs of the existing technology, the present invention provides an automated disassembly equipment and method for wheeled brake discs. Through automatic transportation, automatic disassembly, automatic recovery of bolts and nuts, automatic separation of discs and calipers, automatic grinding of brake discs, and automatic rotation of calipers, the equipment automates the transportation, bolt removal, disc disassembly, grinding, and conveying operations of brake discs.

[0004] To achieve the above objectives, according to one aspect of the present invention, an automated disassembly device for wheeled brake discs is provided, comprising a feeding and automatic disassembly line, a wheel disc receiving and conveying line connected to the end of the feeding and automatic disassembly line for receiving disassembled wheel discs, a wheel disc transfer and reversing mechanism installed at the end of the wheel disc receiving and conveying line for adjusting the direction of the wheel discs, a wheel disc 180° flipping mechanism installed at the end of the wheel disc transfer and reversing mechanism, a wheel disc buffer line installed at the end of the wheel disc 180° flipping mechanism, a brake disc grinding conveying line, and an automatic brake disc gripping and hoisting mechanism;

[0005] The feeding and automatic disassembly line includes a ground rail conveyor line, which includes a bottom rail and a workpiece positioning area, a workpiece buffer position, a brake disc disassembly position, and a disc separation position arranged in sequence. The brake disc grinding conveyor line is connected to the disc separation position. The brake disc automatic gripping and hoisting mechanism is connected across the disc separation position of the ground rail conveyor line and part of the brake disc grinding conveyor line.

[0006] The feeding and automatic disassembly line also includes a hollow wheel disc flipper installed at the starting position of the ground rail conveyor to switch between vertical and horizontal workpiece postures, a retractable wheel disc positioning mechanism installed on the inner top of the workpiece positioning area, a brake disc disassembly machine located on the side of the brake disc disassembly position, an automatic bolt and nut recycling mechanism located in the lower space of the brake disc disassembly machine, a wheel disc transfer car and a disc separation transfer car moving on the bottom rail.

[0007] Furthermore, the brake disc disassembly machine includes a frame, a vertical lead screw slide rail rigidly fixed to the side of the frame, an L-shaped fixing plate slidably connected thereon, and a disassembly head installed on the fixing plate.

[0008] Furthermore, the disassembly head includes a disassembly head horizontal rotation mechanism fixed to the side plate of the L-shaped fixing plate, a dual-axis brake disc disassembly loosening mechanism, a nut adsorption mechanism, and a nut automatic ejection and recycling mechanism that ejects the adsorbed nuts into the recycling pipe.

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

[0010] Furthermore, the automatic bolt and nut recycling mechanism includes a support frame with slide rails on both sides, a horizontal feeding mechanism with slide rails on the top, a receiving tray that slides on the slide rails of the horizontal feeding mechanism, and a brake disc bottom bolt anti-reaction anti-rotation mechanism with one end connected to the receiving tray and the other end sliding on the slide rails on both sides of the support frame.

[0011] Furthermore, the 180° rotating mechanism of the disc includes a gantry truss mechanism, on which a vertical bidirectional slide rail is provided, and a connecting plate is slidably connected. A disc rotating mechanism is installed on the connecting plate, and a disc fork positioning mechanism is fixedly connected to one end of the disc rotating mechanism.

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

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

[0014] Furthermore, the automatic gripping and hoisting mechanism for the brake disc includes a column fixed to the ground. The top of the column is connected by two first connecting beams and two second connecting beams with slide rails. A first sliding beam is vertically slidably connected to the top of the two second connecting beams. A second sliding beam that can slide up and down is slidably connected to the side of the first sliding beam. A pneumatic three-jaw opening and closing mechanism is connected to the end of the second sliding beam.

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

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

[0017] S200: The wheel disc transfer cart moves to directly below the wheel disc positioning mechanism, and after being lifted, 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 disc positioning mechanism retracts, and the wheel disc transfer cart transports the workpiece to directly below 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 disc transfer cart returns to the workpiece buffer position. Subsequently, the hollow wheel disc flipper rotates 90° in the opposite direction and returns to the loading posture.

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

[0019] S400: After the brake disc bolts are removed, the automatic bolt and nut recovery mechanism under the brake disc dismantling machine is retracted; the disc separation and transfer vehicle moves to the bottom of the brake disc dismantling machine, positions and grips the workpiece, and lifts and transfers the workpiece to the disc separation station;

[0020] S500: At the disc separation station, after the disc separation transfer car clamps the disc through the first center positioning clamping mechanism, the brake disc automatic gripping and hoisting mechanism moves to the top of the workpiece, grabs the brake disc on the upper part of the workpiece and puts it into the brake disc grinding conveyor line, enters the brake disc automatic grinding process and unloads the material.

[0021] S600: The disc separation and transfer vehicle continues to lift the middle disc and the lower brake disc. After clamping the lower brake disc through the hollow brake disc three-jaw positioning and clamping mechanism, it is pulled down together with the disc separation and transfer vehicle. The middle disc is transported to the disc receiving and conveying line to continue to flow backward. It passes through the disc transfer and reversing mechanism, the disc 180° flipping mechanism and the disc buffer line in sequence to enter the next process.

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

[0023] In summary, compared with the prior art, the above-described technical solutions conceived by this invention can achieve the following beneficial effects:

[0024] 1. The present invention discloses an automated disassembly equipment for wheel-mounted brake discs. The equipment utilizes a hollow wheel disc turning machine in the feeding and automatic disassembly line to feed the workpiece, a brake disc disassembly machine to loosen the brake disc nuts, and an automatic nut and bolt recycling mechanism to classify and recycle the nuts and bolts. After removing the bolts and nuts, the wheel-mounted brake discs are picked up by a disc-disc separation and transfer vehicle in conjunction with an automatic brake disc grabbing and hoisting mechanism, and then transported to a brake disc grinding conveyor line for grinding and unloading. The intermediate wheel discs are then separated by a wheel disc connection conveyor line and transported backwards for unloading. This completes the transportation, bolt removal, disc separation, grinding, and conveying operations of the wheel-mounted brake discs, achieving fully automated assembly line operation, saving labor resources, and reducing the operation time from 15 minutes per disc to 5 minutes per disc, thus improving maintenance efficiency.

[0025] 2. The automated disassembly equipment for wheel-mounted brake discs of the present invention achieves precise positioning of the center hole of the wheel disc and the fixing bolt hole of the brake disc by designing a central positioning clamping mechanism and a three-jaw chuck mechanism. Compared with the prior art, it eliminates the steps of visual camera image recognition calculation and image analysis, saves operation time and improves work efficiency.

[0026] 3. The automated disassembly equipment for wheeled brake discs of the present invention is equipped with an operation control system. By introducing information technology, it eliminates the drawbacks of manual recording of workpiece numbers, which led to loss of operation data and inability to trace operation process data. It realizes data connection between various mechanisms and modules, and achieves fully digital automatic operation and data traceability. Attached Figure Description

[0048] Example 1

[0049] like Figure 1As shown, this embodiment of the invention provides an automated disassembly device for wheel-mounted brake discs, including a feeding and automatic disassembly line 1, a wheel disc connection conveyor line 2, a wheel disc transfer and reversing mechanism 3, a wheel disc 180° flipping mechanism 4, a wheel disc buffer line 5, a brake disc grinding conveyor line 6, and a brake disc automatic gripping and hoisting mechanism 7. The feeding and automatic disassembly line 1 serves as the starting station, responsible for the initial feeding and disassembly of the wheel-mounted brake discs. The wheel disc connection conveyor line 2 is connected to the end of the feeding and automatic disassembly line 1 by fastening screws, receiving the disassembled wheel discs and conveying them to the wheel disc transfer and reversing mechanism 3, which is connected to the end of the wheel disc connection conveyor line 2, to complete the disassembly of the wheel discs. The direction of the disc is adjusted, and the 180-degree disc flipping mechanism 4 is connected to the end of the disc transfer and reversing mechanism 3. This mechanism continues to receive the disc and completes a 180° flip. The flipped disc is then buffered by the disc buffer line 5, which is connected to it. The feeding and automatic disassembly line 1 includes a disc separation position 145. The brake disc grinding conveyor line 6 is installed corresponding to the disc separation position 145. The automatic brake disc gripping and hoisting mechanism 7 is connected across the disc separation position 145 and the brake disc grinding conveyor line 6, gripping the brake disc and transporting it to the brake disc grinding conveyor line 6. The brake disc grinding conveyor line 6 grinds the disassembled brake disc. Each mechanism is leveled and fixed to the ground using adjustable anchor bolts to ensure the overall stability of the equipment. Through the coordinated operation of each mechanism, a streamlined operation is achieved for the disc brake disc, from transportation, bolt removal, disc disassembly, grinding, and conveying.

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

[0051] like Figure 3As shown, the hollow wheel disc turning machine 11 is set at the workpiece starting position at one end of the ground rail conveyor line 14. It includes a fixed frame 111, a turning mechanism 112, a fixing mechanism 113, a hollow wheel disc support structure 114, and a wheel disc horizontal transfer mechanism 115. The fixed frame 111 serves as the main support, and the turning mechanism 112 is hinged to its upper part. The turning mechanism 112 can switch between a 0° vertical posture and a 90° horizontal posture. The hollow wheel disc support structure 114 is fixed on both sides of its upper surface, and the wheel disc horizontal transfer mechanism 115 is installed in the middle. The fixing mechanism 113 is installed on both sides of the hollow wheel disc support structure 114. When material needs to be loaded, the flipping mechanism 112 rotates to a 0° vertical position, loads the material onto the hollow wheel disc support structure 114, and fixes the wheel brake disc through the fixing mechanism 113. Then, the flipping mechanism 112 flips 90° to a horizontal position, and the wheel disc horizontal transfer mechanism 115 transports the workpiece to the center position of the wheel disc positioning mechanism 12 for 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 buffer position 143, a brake disc disassembly position 144, and a disc separation position 145. The bottom rail 141 is provided with a linear slide rail and a linear rack. The disc positioning mechanism 12 is installed at the top of the workpiece positioning area 142 for positioning the outer circle of the disc. The brake disc disassembly position 144 is provided with a workpiece clamping mechanism at the top for clamping the workpiece.

[0053] The disc positioning mechanism 12 is located on the top inner side of the workpiece positioning area 142 of the ground rail conveyor line 14, and is V-shaped. It works in conjunction with the hollow disc turning machine 11. When the hollow disc turning machine 11 transports the workpiece to the center of the workpiece positioning area 142, the disc positioning mechanism 12 extends under the drive of the cylinder to clamp and position the workpiece.

[0054] like Figure 5As shown, the wheel-shaped transport vehicle 13 includes a first slide rail drive mechanism 131, a first vertical lifting mechanism 132, a first center positioning and clamping mechanism 133, a pneumatic brake mechanism 134, and a bolt hole circumferential positioning mechanism 135. The bottom of the wheel-shaped transport vehicle 13 engages with the bottom rail 141 of the track conveyor line 14 via a linear slide rail and a gear and rack mechanism. The first slide rail drive mechanism 131 drives the vehicle body to move on the track conveyor line 14. The vertical lifting mechanism 132 is installed below the vehicle body, and a lifting platform and servo motor are used to lift the vehicle. The motor enables the vertical lifting and lowering of the workpiece. The guide column lifting platform is equipped with the first center positioning clamping mechanism 133 and the pneumatic three-grip positioning chuck. The first center positioning clamping mechanism 133, the pneumatic three-grip positioning chuck and the positioning boss are used to position and clamp the center hole of the workpiece. The pneumatic brake mechanism 134 is installed on the side of the first center positioning clamping mechanism 133 to brake and position the workpiece. The bolt hole circumferential positioning mechanism 135 is set at a 45° inclination angle on the guide column lifting platform to position the brake disc fastening bolt in the circumferential direction.

[0055] like Figure 6 As shown, the brake disc disassembly machine 15 is located on the side of the brake disc disassembly position 144, and includes a frame 151, a vertical screw slide rail 152, a vertical screw slide rail drive mechanism 157, and a disassembly head. 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 an automatic nut ejection and recycling mechanism 156. The frame 151, as an integral support structure, has an open space at its lower part for cooperating with the track conveyor line 14 to install the automatic bolt and nut recycling mechanism 17. The upper part, facing the track conveyor line 14, has two vertical screw slide rails 152 rigidly fixed on its surface. The L-shaped fixing plate is slidably connected to it and serves as the support base for the disassembly head. The upper end of the disassembly head is connected to the top plate of the L-shaped fixing plate, and the side is fixed to the side plate of the L-shaped fixing plate by the horizontal rotation mechanism 153 of the disassembly head. The disassembly head is driven to move up and down along the vertical screw slide rail by the vertical screw slide rail by the vertical screw slide rail. The horizontal rotation mechanism 153 of the disassembly head rotates the disassembly head horizontally. The disassembly head is also equipped with the dual-axis brake disc disassembly machine loosening mechanism 154 for loosening the workpiece nut, the nut adsorption mechanism 155 for adsorbing the loosened nut, and the nut automatic ejection and recycling mechanism 156 for ejecting the adsorbed nut into the recycling pipe.

[0056] When the disc transfer cart 13 transports the workpiece to the area below the disassembly head and clamps it with the workpiece clamping mechanism at the brake disc disassembly position 144 on the track conveyor line 14, the disassembly head moves down, and the dual-axis brake disc disassembly machine loosening mechanism 154 loosens the fixing nut on the brake disc. Then, the disassembly head horizontal rotation mechanism 153 rotates to a fixed angle and continues to tighten and loosen the next set of nuts. At the same time, the nut adsorption mechanism 155 aligns with the nut position loosened in the previous process and adsorbs the nut. After the second set of nuts is loosened, the entire disassembly head is raised, and the nut automatically pops out of the recycling mechanism 156. The push rod feeding mechanism inside the nut adsorption mechanism 156 pops the nut below the nut adsorption mechanism 155 into the nut recycling pipe, completing the automated recycling of the loosened nuts. This cycle repeats continuously.

[0057] like Figure 7 As shown, the disc-and-panel separation and transfer vehicle 16 includes a second slide rail drive mechanism 161, a second vertical lifting mechanism 162, a second center positioning and clamping mechanism 163, and a hollow brake disc three-jaw positioning and clamping mechanism 164. The bottom of the disc-and-panel separation and transfer vehicle 16 engages with the bottom rail 141 of the track conveyor line 14 via a linear slide rail and a gear and rack mechanism. The second slide rail drive mechanism 161 drives the vehicle body to move on the track conveyor line 14. The second vertical lifting mechanism 162 is installed below the vehicle body, and is raised and lowered by a lift and guide column. The platform and servo motor enable the vertical lifting of the workpiece. The guide column lifting platform is equipped with the second center positioning and clamping mechanism 163, the pneumatic three-jaw positioning chuck, and the hollow brake disc three-jaw positioning and clamping mechanism 164. The second center positioning and clamping mechanism 163, the pneumatic three-jaw positioning chuck, and the positioning boss enable the positioning and clamping of the workpiece's center hole. The hollow brake disc three-jaw positioning and clamping mechanism 164 enables the positioning and clamping of the lower brake disc of the workpiece. It cooperates with the second vertical lifting mechanism 162 to enable the disassembly of the lower brake disc.

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

[0059] When the wheel disc transfer cart 13 transports the workpiece to the brake disc disassembly position 144 of the track conveyor line 14 and the transfer cart leaves, the receiving tray 174 extends from the cabinet of the brake disc disassembly machine 15 frame 151 through the horizontal feeding mechanism 172. Then, the third vertical lifting mechanism 171 rises and contacts the bolt head at the bottom of the workpiece through the anti-reaction mechanism 173 of the bottom bolt of the brake disc. After 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 retracts 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 disc transfer cart 13 can pass through the track below the brake disc disassembly position 144 and transport the brake disc and wheel disc workpiece with the bolts removed to the next process.

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

[0061] The disc transfer and reversing mechanism 3 includes a base, a horizontal turntable, a disc positioning mechanism, and a disc driving mechanism. The horizontal turntable rotates to achieve smooth connection with the disc connection conveyor line 2 and the disc 180° flipping mechanism 4. Specifically, the discs that arrive at the disc connection conveyor line 2 are connected through the disc transfer and reversing mechanism 3. After the discs are transferred to this mechanism, the horizontal turntable rotates 90°, the disc driving mechanism reverses its operation, aligns the discs with the disc 180° flipping mechanism 4, and connects with it. The discs are then transferred to the disc 180° flipping mechanism 4. The mechanism then rotates 90° in the opposite direction to return to its original position, ready for the next connection.

[0062] like Figure 9As shown, the 180° rotating mechanism 4 is used when the workpiece is in a position with the wheel rim facing down. When the workpiece passes through this mechanism, the wheel rim is rotated 180° so that the wheel rim faces up, facilitating transportation to the wheel rim buffer line 5 for robotic arm hoisting and clamping. It includes a wheel rim conveyor line 41, a gantry truss mechanism 42, a bidirectional slide rail 43, a wheel rim fork positioning mechanism 44, and a wheel rim rotating mechanism 45. The wheel rim conveyor line 41 spans over the two long sides of the bottom of the gantry truss mechanism 42, and the vertical support is provided on the column of the gantry truss mechanism 42. A straight bidirectional slide rail 43 has two connecting plates slidably connected to it. The disc rotating mechanism 45 is fixed on the connecting plates, and the disc fork positioning mechanism 44 is installed at one end of the plate. This mechanism connects the disc to the disc transfer and reversing mechanism 3 and is transported to the center position by the disc conveyor line 41. The disc fork positioning mechanism 44 slides down the vertical bidirectional slide rail 43 to clamp and position the disc. Under the action of the disc rotating mechanism 45, it rotates 180° and continues to be transported by the disc conveyor line 41 to the disc buffer line 5 for the next process.

[0063] like Figure 10 As shown, the top of the disc buffer line 5 is equipped with a roller structure, surrounded by a steel structure. Multiple rollers are driven to rotate by a chain mechanism to transport the discs conveyed from the disc 180° flipping mechanism 4. The rollers have a steel structure inside and are wrapped with polyurethane rubber on the outside. They are thin in the middle and thick at both ends, shaped like a dumbbell. The thin part in the middle is used to avoid the outer circular stepped surface of the center hole of the disc, ensuring that the disc is horizontal and easy to pass through.

[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 chamber 63, and a brake disc connecting and tilting unloading mechanism 64. The brake disc conveyor line 61 is a belt-driven system with one set of belts on each side and an overhead section in the middle for mounting the brake disc grinder 62. The brake disc dust removal chamber 63 is fitted around the brake disc grinder 62. The bottom of the brake disc conveyor line 61 is a steel structure, driven by a servo motor and synchronous belt, ensuring smooth and reliable operation. It passes through the interior of the brake disc dust removal chamber 63. The brake disc grinder 62 is located inside the brake disc dust removal chamber 63, in the middle of the brake disc conveyor line 61. The brake disc connecting and tilting unloading mechanism 64 is located at the end of the brake disc conveyor line 61, connecting the ground brake discs.

[0065] like Figure 13As shown, the brake disc grinding machine 62 includes a base 621, a fourth vertical lifting platform 622, a brake disc rotation mechanism 623, a brake disc clamping and positioning mechanism 624, a grinding head rotation mechanism 625, and a grinding head moving mechanism 626. The fourth vertical lifting platform 622 is mounted on the base 621. The brake disc rotation 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, which fixes the brake disc, is mounted on the upper part of the brake disc rotation mechanism 623. 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 placed onto the brake disc conveyor line 61 by the automatic brake disc gripping and hoisting mechanism 7, it is transported to the brake disc dust removal chamber 63. At this time, the fourth vertical lifting platform 622 rises, and the three-jaw mechanism of the brake disc clamping and positioning mechanism 624 passes through the center hole of the brake disc and clamps it. The brake disc is rotated by the lower brake disc rotation mechanism 623. The grinding head moves closer to the edge of the brake disc via the grinding head moving mechanism 626. The grinding head rotates under the power of the grinding head rotating mechanism 625 to perform grinding operations on the outer circle of the brake disc. After the operation is completed, the grinding head stops rotating, the grinding head moving mechanism 626 retracts, the fourth vertical lifting platform 622 descends, and the brake disc conveyor line 61 continues to operate, transporting the brake disc to the brake disc connecting and flipping unloading mechanism 64.

[0067] like Figure 14 As shown, the brake disc connecting and flipping unloading mechanism 64 includes a fixed frame 641, a rotating disk 642, a rotary drive mechanism 643, a brake disc positioning mechanism 644, and a brake disc transfer and rolling mechanism 645. The rotating disk 642 is installed on the top of the fixed frame 641 and is driven to rotate 90° by the rotary drive mechanism 643 installed in the middle of the fixed frame 641. The brake disc transfer and rolling mechanism 645 is arranged on the upper part of the rotating disk 642, and the brake disc positioning mechanism 644 is installed on the side. After the brake disc is polished, the brake disc connecting and flipping unloading mechanism 64 connects the brake disc workpiece from the brake disc conveyor line 61, and the brake disc transfer and rolling mechanism 645 transfers the workpiece to the rotating disk 642. The brake disc positioning mechanism 644 positions the brake disc workpiece, and the rotary drive mechanism 643 rotates the brake disc workpiece 90°, making it convenient for workers to lift, pack, and transport it to the next process.

[0068] like Figure 15As shown, the automatic brake disc gripping and hoisting mechanism 7 is in the form of a gantry truss, including columns 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-jaw opening and closing mechanism 76. This mechanism is fixed to the ground by the four columns 71. The top of the columns 71 is connected by the two first connecting beams 72 and the two second connecting beams 73. The first connecting beams 72 and the second connecting beams 73 are provided with slide rails. 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, which can slide up and down. The first sliding beam 74 and the second sliding beam 75 enable movement at any point within the coverage area of ​​the gantry truss. The pneumatic three-jaw opening and closing mechanism 76 is connected to the end of the second sliding beam 75. The brake disc fixing claw is connected to the bottom of each moving claw by fastening screws for gripping the brake disc.

[0069] The device in this embodiment of the 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 traceability and query of subsequent operation results.

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

[0071] S100: The workpiece with wheeled brake disc is fed by the hollow wheel disc turning machine 11 and then turned 90° to change the workpiece from a vertical posture to a horizontal posture. The wheel disc horizontal transfer mechanism 115 transports the workpiece to the wheel disc positioning mechanism 12 in the workpiece positioning area 142. The wheel disc positioning mechanism 12 clamps the outer circle of the workpiece by extending a V-block to achieve the center positioning of the workpiece.

[0072] S200: The wheel disc transfer cart 13 moves to directly below the wheel disc positioning mechanism 12, the first vertical lifting mechanism 132 rises, inserts the first center positioning clamping mechanism 133 into the center inner hole of the workpiece, the pneumatic three-jaw mechanism opens to clamp the workpiece, the V-block of the wheel disc positioning mechanism 12 retracts, and the wheel disc transfer cart 13 transports the workpiece to directly below the brake disc dismantling machine 15 at the brake disc dismantling position 144 (if the work at the brake disc dismantling machine 15 station is not completed, the wheel disc transfer cart 13 transports the workpiece to the workpiece buffer position 143 for buffering), clamps the workpiece through the workpiece clamping mechanism at the top of the brake disc dismantling position 144, and the wheel disc transfer cart 13 returns to the workpiece buffer position 143; subsequently, the hollow wheel disc flipper 11 rotates 90° in the opposite direction and returns to the loading posture.

[0073] S300: The automatic bolt and nut recycling mechanism 17 extends and retracts the receiving tray 174 to directly below the workpiece to prepare for receiving materials; the dual-axis brake disc dismantling machine loosening mechanism 154 descends to loosen the brake disc nuts; the nut adsorption mechanism 155 attracts the nuts with a magnet, and the nut automatic ejection recycling mechanism 156 inside the mechanism ejects the nuts below the magnet into the nut recycling pipe, realizing the recycling 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 recycling box, realizing the automatic recycling of bolts;

[0074] S400: After the brake disc bolts are removed, the automatic bolt and nut recovery mechanism 17 under the brake disc dismantling machine is retracted; the disc separation and transfer vehicle 16 moves to the bottom of the brake disc dismantling machine 15, and inserts the middle three-jaw telescopic mechanism of the pneumatic three-jaw positioning chuck into the center hole of the workpiece, lifting the workpiece and transferring it to the disc separation station 145.

[0075] S500: At the disc separation station 145, after the disc separation transfer car 16 clamps the disc through the first center positioning clamping mechanism 133, the brake disc automatic gripping and hoisting mechanism 7 moves to directly above the workpiece, grabs the top brake disc and puts it into the brake disc grinding conveyor line 6, and enters the brake disc automatic grinding process.

[0076] S600: The disc separation and transfer vehicle 16 continues to lift the middle disc and the lower brake disc. After clamping the lower brake disc of the disc through the hollow brake disc three-jaw positioning and clamping mechanism 164, it is pulled down together with the disc separation and transfer vehicle 16. The middle disc is transported to the disc receiving and conveying line 2 and continues to flow backward. It passes through the disc transfer and reversing mechanism 3, the disc 180° flipping mechanism 4 and the disc buffer line 5 in sequence to enter the next process.

[0077] S700: The disc separation and transfer vehicle 16 transports the lower brake disc to the disc separation station 145, lifts it up, releases the grippers, and cooperates with the brake disc automatic gripping and hoisting 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 recycling of the disc cake.

[0079] Those skilled in the art will readily understand that the above description is merely 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 within the scope of protection of the present invention.
