In the initial state, the discs 37 are not clamped on both clamping mechanisms 5, and the two guide rails 18 on each clamping mechanism 5 are combined into a complete circular ring, the two semicircular plates 22 on each clamping mechanism 5 are combined into a complete circular plate, and the two semi-cylinders 24 on each clamping mechanism 5 are combined into a complete cylinder. The complete cylinders in the two clamping mechanisms 5 are distributed up and down. The two positioning posts 28 in each clamping mechanism 5 are 180 degrees apart circumferentially and the spring B26 is in a compressed state, the two clips 35 on each clamping mechanism 5 are both in a state of not locking the disc 37, and the spring C36 is in a stretched state. The spring a16 in each clamping mechanism 5 is in a compressed state, and the two lock bars 40 are inserted into the lock grooves 21 on the corresponding guide rails 18 to lock the corresponding two guide rails 18.

When the disc 37 is required to be turned and ground by using the invention, the glass door 3 is opened to respectively mount the disc 37 on the two semi-cylinders 24 of each clamping mechanism 5, so that the two positioning posts 28 on each clamping mechanism 5 are respectively inserted into the two bolt holes 39 on the corresponding disc 37, and the two clamping blocks 35 on each clamping mechanism 5 are positioned in the range of the axle holes 38 on the corresponding disc 37.

Then, a motor C46 in the upper clamping mechanism 5 is started, the motor C46 drives the corresponding two semicircular plates 22 to rotate rapidly through the shaft sleeve 44, the ejector rod 17, the gear C42 and the gear ring 41, the two semicircular plates 22 drive the two semi-cylinders 24 to rotate synchronously and rapidly, the disc 37 is kept stationary due to inertia hysteresis of the two semi-cylinders 24, the two positioning columns 28 respectively drive the corresponding sliding seat B27 to slide to the limit position around the axis of the semicircular plates 22 and compress the spring B26 further, and the two sliding seats B27 respectively pull the corresponding sliding seat C30 to slide to the limit position along the radial direction of the semicircular plates 22 through the corresponding pull ropes 29 and stretch the corresponding spring C36 further.

The two sliding seats C30 drive the corresponding clamping blocks 35 to synchronously move to the limit positions through the corresponding guide seats B31 and the sliding seats D34 respectively, and lock the disc 37 through the wheel shaft holes 38 in the middle of the disc 37.

When the two clamping blocks 35 lock the disc 37, the disc 37 is driven to start to rotate synchronously and rapidly due to the fact that the two positioning columns 28 move to the limit in the corresponding sliding grooves C25. Then, the motor D51 and the motor E55 are started to drive the turning tool 53 on the slide F52 to turn the upper side of the disc 37. After the turning mechanism 48 finishes turning the disc 37, the turning tool 53 on the sliding seat F52 is driven by the starting motor D51 and the motor E55 to reset and separate from the disc 37. Then, the motor F59 and the motor G64 are started to drive the grinding wheel a61 and the grinding wheel B62 on the carriage H60 to grind the lower side and the upper side of the disc 37, respectively. After the grinding mechanism 56 finishes grinding the disc 37, the starting motor F59 and the motor G64 drive the grinding disc A61 and the grinding disc B62 on the sliding seat H60 to reset and separate from the disc 37.

After the upper disc 37 is processed, a motor C46 in the clamping mechanism 5 where the upper disc 37 is positioned is stopped, after the corresponding two semi-cylinders 24 stop rotating, the two sliding seats B27 drive the disc 37 to rotate and reset relative to the two semi-cylinders 24 through the positioning columns 28 under the reset action of the corresponding springs B26, and the two sliding seats C30 drive the clamping blocks 35 to radially separate from the disc 37 through the corresponding guide seats B31 and the sliding seats D34 under the reset action of the corresponding springs C36, so that the unlocking of the disc 37 is completed.

Then, after the upper circular disc 37 is taken down from the corresponding two semi-cylinders 24, the two motors B15 in the clamping mechanism 5 where the upper circular disc 37 is located are started, the two motors B15 drive the corresponding rod sleeve B11 to shrink inwards towards the corresponding rod sleeve A10 through the corresponding gears B14, the gears A13 and the racks 12 respectively, and the two rod sleeves B11 drive the semi-cylinders 24 to move towards the corresponding guide seats A6 through the corresponding springs A16, the ejector rods 17, the guide rails 18, the guide bars 23 and the semicircular plates 22 respectively. The two half cylinders 24 in the chuck 5 on which the upper disc 37 is located are separated by a sufficient distance. During the separation of the two half cylinders 24, the two locking bars 40 are respectively disengaged from the locking grooves 21 on the respective rails 18 and unlock the locking of the two rails 18.

Then, four motors A9 in the two clamping mechanisms 5 are started simultaneously, and the two motors A9 in the clamping mechanism 5 where the upper semicircular plate 22 is located drive corresponding sliding seats A7 to move downwards through corresponding screw rods A8, and the two sliding seats A7 drive corresponding semi-cylinders 24 to move downwards synchronously for a certain distance through corresponding rod sleeves A10, rod sleeves B11, ejector rods 17, guide rails 18, guide bars 23 and semicircular plates 22. Simultaneously, two motors A9 in the clamping mechanism 5 where the lower circular disc 37 is positioned drive the circular discs 37 on the two semi-cylinders 24 to synchronously move upwards by a certain amplitude through a series of transmission respectively.

After the semi-cylinders 24 in the two clamping mechanisms 5 finish the up-down position alternation, a motor C46 in the clamping mechanism 5 where the disc 37 positioned above is positioned is started, and the motor C46 drives the corresponding disc 37 to rotate quickly through a series of transmission and finishes the automatic locking of the disc 37 when the disc 37 starts to rotate and starts to start.

During the process of grinding the disc 37 by the turning mechanism 48 and the grinding mechanism 56, the motor C46 in the clamping mechanism 5 where the lower semi-cylinder 24 is located is started, the motor C46 drives the corresponding two semi-cylinders 24 to be combined into a complete cylinder through a series of transmission, and the two lock rods 40 are reinserted into the lock grooves 21 on the corresponding guide rails 18 to lock the two guide rails 18. Then, the disks 37 are mounted on the two half cylinders 24 downward, so that the two positioning posts 28 are respectively inserted into the two bolt holes 39 on the disks 37 to complete the mounting.

Thus, the two clamping mechanisms 5 are used for finishing the installation of the other disc 37 on the clamping mechanism 5 below in the process of processing the disc 37 in a reciprocating and alternating mode, and the clamping mechanism 5 is used for finishing the locking of the disc 37 on the two semi-cylinders 24 in the process of driving the disc 37 to rotate at a high speed.

After the disc is replaced by the brake disc, the double sides of the brake disc can be efficiently machined.
