A lifting driving mechanism for driving the air outlet pipeline 11 to reciprocate up and down is arranged below the workbench 2, a base is connected to the driving output end of the lifting driving mechanism, the air outlet pipeline 11 is rotatably arranged on the base, a rotary driving assembly for driving the air outlet pipeline 11 to rotate is arranged on the base, and the air outlet pipeline 11 is connected to the lifting output end of the lifting driving mechanism. The air outlet duct 11 and the air outlet cap 33 move up and down and simultaneously rotate, and the air discharged from the air outlet passage 331 is blown to various positions on the table 2 by the air outlet cap 33, so that the chips falling on the table 2 are blown off.
When the brake disc 4 is used, the brake disc 4 is placed on the positioning boss 3 which is moved to the feeding station at the feeding station, the positioning column 5 is penetrated in the inner hole of the brake disc 4, then the brake disc 4 rotates to the clamping and positioning station along with the workbench 2, the lifting cylinder II 15 drives the pushing plate 16 to move downwards, the pushing plate 16 pushes the movable piece 6 to move downwards, the pushing inclined surface 605 on the pushing block 603 pushes the limiting block 27 out of the accommodating groove 501, the outer end of the limiting block 27 moves to the position above the brake disc 4, the subsequent pushing block 603 continuously moves downwards to drive the positioning column 5 to move downwards, and the limiting block 27 compresses the brake disc 4 on the positioning boss 3 from top to bottom along with the downward movement of the positioning column 5. When the positioning column 5 moves downwards, the first connecting ring 18 is driven to move downwards, the arc-shaped elastic piece 19 is bent, and the arc-shaped elastic piece 19 outwards protrudes and presses the inner wall of the brake disc 4. When the movable member 6 moves down to the state that the brake disc 4 is supported tightly by the arc-shaped elastic member 19, the latch 261 is inserted into the corresponding clamping groove 604, so that the position of the movable member 6 in the up-down direction is fixed, and when the pushing plate 16 leaves the movable member 6, the movable member 6 does not move upwards any more, and the brake disc 4 is kept in a tightly supported and fixed state.
Then the brake disc 4 rotates to a drilling station along with the workbench 2, the trigger block 20 moves between two clamping heads of the double-head clamping cylinder at the drilling station and is clamped by the double-head clamping cylinder, the rotary driving mechanism II 10 drives the positioning bulge to drive the brake disc 4 to rotate, the rotation of the brake disc 4 is stopped after each rotation of the brake disc 4 by a set angle, and the drill bit 102 moves downwards to drill the assembly hole at a preset position on the brake disc 4 when the rotation of the brake disc 4 is stopped until the assembly hole on the brake disc 4 is completely machined.
The double-end clamping cylinder at the drilling station loosens the trigger block 20, the brake disc 4 rotates to the chip removing station along with the workbench 2, the lifting cylinder I13 drives the chip blocking cover 14 to move downwards, the chip blocking cover 14 moves to the bottom end to be in contact with the workbench 2, the structures on the brake disc 4, the positioning boss 3 and the positioning boss 3 are completely blocked on the inner side of the chip blocking cover 14, the rotary driving mechanism I9 is started, and the brake disc 4 is driven to rotate at a higher speed, so that chips on the brake disc 4 and the positioning boss are thrown out under the centrifugal action.
The brake disc 4 rotates to the feeding station along with the workbench 2, the trigger block 20 is contacted with the inclined plate section 801 and pushed by the inclined plate section 801 to move upwards, the unlocking ring 23 is driven to move upwards, the two toothed plates 26 are pushed away from each other, the clamping teeth 261 leave the clamping grooves 604, unlocking of the movable piece 6 is achieved, the movable piece 6 moves upwards to reset, the limiting block 27 leaves the brake disc 4, and the arc-shaped elastic piece 19 loosens the brake disc 4, so that the brake disc 4 can be taken down. After the brake disc 4 with the hole drilled is removed, a new brake disc 4 to be processed is put in the station, and the steps are repeated to perform a new round of processing.
When a certain number of brake discs 4 are processed, and more chips are accumulated on the workbench 2, the workbench 2 is stopped to be driven to rotate, the cleaning mechanism is started, the air outlet pipeline 11 and the air outlet cap 33 are driven to reciprocate up and down, meanwhile, the air exhausted by the air outlet channel 331 blows onto the workbench 2 in the process, the blown air contacts with all areas above the workbench 2 along with the rotation and the up-down movement of the air outlet cap 33, and the chips above the workbench 2 are blown down, so that the space above the workbench 2 is cleaned.
The clamping device can better clamp and fix the brake disc 4, and avoid surface damage to the edge of the brake disc 4. The multi-station drilling machine is used for drilling the brake disc 4, so that the machining efficiency can be improved. The invention can effectively clean all the places above the workbench 2 by arranging the cleaning mechanism.
