The driving motor 52 is installed on the workbench 3. The driving gear 53 is connected to the output shaft of the driving motor 52. The driving gear 53 is meshed with the inner ring gear 51, so that the operation of the driving motor 52 can drive the inner ring gear 51 to rotate through the driving gear 53, thereby driving the swivel 4 to rotate.

[0035] The discharge mechanism includes a guide rod 61, a supporting seat 62 and a transmission gear 63. A plurality of guide rods 61 are rotatably connected to the swivel 4 at even intervals along the circumferential direction.

The upper right part of the bracket 2 is connected to the L-shaped mounting plate 71, the lower part of the L-shaped mounting plate 71 is installed with a servo motor 72, the left side of the L-shaped mounting plate 71 is rotatably connected to the spline shaft 73, the upper and lower sides of the spline shaft 73 are slidably connected to the connecting plate 74, the connecting plate 74 is slidably connected to the L-shaped mounting plate 71, the connecting plate 74 is rotatably connected to the rotating sleeve 79, and the rotating sleeve 79 is slidably connected to the spline shaft 73. A grinding disc 75 is rotatably connected to the left side of the connecting plate 74, and a belt transmission group 1 76 is wound between the rotating sleeve 79 and the grinding disc 75, so that the grinding disc 75 can be driven to rotate when the spline shaft 73 rotates. A belt transmission group 2 77 is wound between the spline shaft 73 and the output shaft of the servo motor 72, so that the operation of the servo motor 72 can drive the spline shaft 73 to rotate together with the belt transmission group 2 77.

[0037] The adjustment component includes a reduction motor 81 and a bidirectional screw 82. The reduction motor 81 is installed on the top of the L-shaped mounting plate 71. The bidirectional screw 82 is connected to the output shaft of the reduction motor 81. The two sides of the bidirectional screw 82 are respectively threadedly matched with the two connecting plates 74, so that the rotation of the bidirectional screw 82 can drive the two connecting plates 74 to move closer to or away from each other through the threads.

[0038] When the brake disc 100 needs to be polished, the present device can be used. When in use, the brake disc 100 can be placed on the supporting seat 62 first, and the brake disc 100 can be sleeved on the upper part of the guide rod 61. Then, the driving motor 52 can be controlled to drive the driving gear 53 to rotate. The rotation of the driving gear 53 drives the inner gear ring 51 and the rotating ring 4 to rotate, thereby driving the guide rod 61 to move to transport the brake disc 100. When the brake disc 100 is sent between the two polishing discs 75, the transmission gear 63 on the guide rod 61 is also connected with the connecting gear 7 8 is engaged, at this time, the driving motor 52 is controlled to stop operating, and then the servo motor 72 is controlled to operate. When the servo motor 72 is in operation, it can drive the connecting gear 78 and the belt transmission group 2 77 to rotate. When the belt transmission group 2 77 rotates, it drives the spline shaft 73 to rotate. When the spline shaft 73 rotates, it can drive the rotating sleeve 79 to rotate. The rotating sleeve 79 rotates and drives the grinding disc 75 to rotate through the belt transmission group 1 76. The grinding disc 75 is used to grind the brake disc 100. When the connecting gear 78 rotates, it can drive the transmission gear 63 and The guide rod 61 rotates, thereby driving the brake disc 100 to rotate. At this time, the brake disc 100 can be polished by the relative rotation of the brake disc 100 and the polishing disc 75. During the polishing process, the brake disc 100 can be placed on other guide rods 61, and the polished brake disc 100 can be removed. After the polishing is completed, the drive motor 52 is controlled to operate to drive the rotating ring 4 to rotate through the drive gear 53 and the inner ring gear 51, so that a new brake disc 100 can be sent between the two polishing discs 75 for polishing, and this process is repeated. , the brake disc 100 can be polished using the device, and after polishing, the polishing disc 75 can be replaced by only controlling the drive motor 52 to operate, which is more convenient and more efficient. In the actual operation, the distance between the two polishing discs 75 can be adjusted according to the thickness of the brake disc 100. When adjusting, it is only necessary to control the reduction motor 81 to drive the bidirectional screw 82 to rotate, and the two connecting plates 74 can be driven to move closer to or away from each other through the thread, thereby adjusting the distance between the two polishing discs 75.

[0039] The guide rod 61 further comprises a fixing mechanism, which comprises a locking frame 91, a slant plate 92, a contact shaft 93, a piston rod 94, a piston block 1 96, an elastic member 1 97, a piston block 2 98 and an elastic member 2 99. A plurality of piston rods 94 are slidably connected to the upper portion of the guide rod 61 at uniform intervals along the circumferential direction. The locking frame 91 is connected to the piston rod 94. A liquid storage cavity 95 is provided in the guide rod 61. The channels of the liquid storage cavity 95 and the piston rod 94 are filled with hydraulic oil. A piston block 1 96 and a piston block 2 98 are slidably connected to the lower portion of the liquid storage cavity 95. An elastic member 1 97 is connected between the piston block 1 96 and the piston block 2 98. , the elastic member 97 is a compression spring, and the upward movement of the piston block 96 can squeeze the hydraulic oil in the liquid storage chamber 95, so that the hydraulic oil squeezes multiple piston rods 94 and the locking frame 91 away from each other, allowing the locking frame 91 to press against the inner wall of the brake disc 100 to fix the brake disc 100. The bottom of the piston block 98 is connected to the contact shaft 93, and the contact shaft 93 is slidably connected to the guide rod 61. An elastic member 99 is connected between the piston block 98 and the bottom of the guide rod 61. The elastic member 99 is a tension spring. The front and rear sides of the L-shaped mounting plate 71 are connected to the inclined plate 92, and the inclined surface of the inclined plate 92 is located at the moving track of the contact shaft 93.

[0040] When the guide rod 61 rotates, it can drive the contact shaft 93 to move together, and when the contact shaft 93 moves, it can contact the inclined surface of the inclined plate 92. At this time, the contact shaft 93 will be squeezed and moved upward by the inclined surface of the inclined plate 92. When the contact shaft 93 moves upward, it drives the piston block 2 98 to move upward, and the elastic member 2 99 is stretched. The upward movement of the piston block 2 98 can drive the piston block 1 96 to move upward through the elastic member 1 97. The upward movement of the piston block 1 96 can squeeze the hydraulic oil in the liquid storage cavity 95, so that the hydraulic oil squeezes the piston rod 94 outward. When the piston rod 94 moves outward, it can drive the locking frame 91 to move, so that the locking frame 91 presses against the inner wall of the brake disc 100, fixes the brake disc 100, and prevents the position of the brake disc 100 from shifting. After the locking frame 91 presses against the brake disc 100, if the piston block 2 98 continues to move, the elastic member 1 97 will be compressed, thereby buffering through the elastic member 1 97.

[0041] It also includes a cleaning mechanism, which includes a liquid storage cylinder 101, a water pump 102, a sleeve frame 103, a connecting frame 106, a shunt pipe 104 and a nozzle 105.

The water pump 102 is installed in the liquid storage cylinder 101. The connecting frame 106 is connected to the right side of the top of the workbench 3. The sleeve frame 103 is connected to the upper and lower sides of the connecting frame 106. The rotation of the swivel 4 can drive the brake disc 100 to rotate between the two sleeve frames 103. The sleeve frame 103 is installed with a nozzle 105, and the shunt pipe 104 is connected between the nozzle 105 and the liquid outlet end of the water pump 102.

[0042] During the grinding process, the water pump 102 can be controlled to extract the coolant in the liquid storage cylinder 101 and inject it into the nozzle 105 through the shunt pipe 104, and the coolant is sprayed on the grinding disc 75 through the nozzle 105 to cool the grinding disc 75.

[0043] It also includes an air pump 111 and an air blowing pipe 112. The air pump 111 is installed on the right side of the bottom of the workbench 3. The air outlet of the air pump 111 is connected to the air blowing pipe 112. The air blowing pipe 112 passes through the workbench 3 and the connecting frame 106. The air outlet of the air blowing pipe 112 is aimed at the brake disc 100. At this time, the air pump 111 can be controlled to blow air through the air blowing pipe 112, so as to clean the brake disc 100 and avoid debris remaining on the brake disc 100 during the grinding process.

[0044] A cleaning brush 12 is also included. The upper and lower frames 103 are both connected with the cleaning brush 12. The brake disc 100 located between the two frames 103 will contact with the cleaning brush 12. At this time, the brake disc 100 rotates and the cleaning brush 12 can clean the surface of the brake disc 100.

[0045] The utility model also includes a protection mechanism, which includes a side panel 131, a shielding cover 132 and a cylinder 133.

The shielding cover 132 is connected to the telescopic rod of the cylinder 133. The extension of the telescopic rod of the cylinder 133 can drive the shielding cover 132 to cover the brake disc 100 and the grinding disc 75, so as to shield the brake disc 100 and the grinding disc 75 and prevent debris from splashing during the grinding process.

[0046] The working process of the present invention is as follows: the brake disc 100 is placed on the supporting seat 62, so that the brake disc 100 is sleeved on the upper part of the guide rod 61, and the driving motor 52 is controlled to drive the driving gear 53 to rotate. The driving gear 53 rotates to drive the inner gear ring 51 and the rotating ring 4 to rotate, and drives the guide rod 61 to move, so as to transport the brake disc 100. When the guide rod 61 moves, it can drive the contact shaft 93 to move together. When the contact shaft 93 moves, it can contact the inclined surface of the inclined plate 92, and then the contact shaft 93 is When the inclined surface of the inclined plate 92 is squeezed and moved upward, the contact shaft 93 moves upward and drives the piston block 2 98 upward, and the elastic member 2 99 is stretched. The piston block 2 98 moves upward and can drive the piston block 1 96 upward through the elastic member 1 97, squeezing the hydraulic oil in the liquid storage cavity 95, so that the hydraulic oil squeezes the piston rod 94 outward, and the piston rod 94 moves outward and drives the locking frame 91 to move against the inner wall of the brake disc 100 to fix the brake disc 100. When the brake disc 100 moves between the two grinding discs 75, the guide The transmission gear 63 on the rod 61 meshes with the connecting gear 78, controls the driving motor 52 to stop operating, and then controls the servo motor 72 to operate. The servo motor 72 drives the connecting gear 78 and the belt transmission group 2 77 to rotate. The belt transmission group 2 77 drives the spline shaft 73 to rotate when rotating. The rotation of the spline shaft 73 drives the rotating sleeve 79 to rotate.
