Sensors on the master and positioning cylinder 451 and the rocker arm cylinder 44 to obtain the positions of the piston rods of the positioning cylinder 451 and the rocker arm cylinder 44, respectively.
After the double-sided lapping machine is assembled, the clamp 7, the sun gear assembly 22 and the outer gear ring assembly 24 form a planetary gear mechanism, the fixed outer teeth 241 and the movable outer teeth 242 form an outer gear ring of the planetary gear mechanism, the clamp 7 is a planetary gear of the planetary gear mechanism, and the sun gear assembly 22 forms a sun gear of the planetary gear mechanism.
As shown in fig. 3 and 4, when the double-sided grinder is used for feeding and discharging, the piston rod of the positioning cylinder 451 is retracted, so that the positioning pin 452 is separated from the positioning pin hole 4531 of the positioning seat 453, and the positioning assembly 45 cannot lock the rocker arm mechanism 4; the piston rod of the rocker arm cylinder 44 extends out, the pivot lug 414 and the positioning frame 413 push the rotating shaft 412 of the rotating arm assembly 41 to rotate, the rotating shaft 412 is linked with the cantilever 42 to swing, the upper grinding disc mechanism 1 swings to the upper side of the water receiving frame 34, the upper grinding disc mechanism 1 is not aligned with the lower grinding disc mechanism 2 at the moment, and a larger space is reserved above the lower grinding disc mechanism 2 for operators to perform feeding and discharging operations.
When an operator performs feeding and discharging operations, the piston rod of the outer tooth cylinder 243 of the outer tooth ring assembly 24 retracts to enable the movable outer tooth 242 to descend, then the piston rod of the sliding cylinder 64 extends to enable the table top 633 of the sliding table top 63 to be close to the lower grinding disc body 231 of the lower grinding disc mechanism 2, the table top 633 and the lower grinding layer 232 are located on the same horizontal plane, during discharging, a worker can directly drag the clamp 7 with the product to be ground into the table top 633 from the lower grinding layer 232 of the lower grinding disc mechanism 2, after discharging is completed, the next batch of product to be ground can be fed, and during feeding, the worker can directly drag the clamp 7 with the product to be ground into the lower grinding layer 232 of the lower grinding disc mechanism 2 from the table top 633.
As shown in fig. 1 and 2, after the loading and unloading operations are completed, the piston rod of the sliding cylinder 64 is retracted, so that the table surface 633 of the sliding table surface 63 is separated from the lower disc body 231 of the lower disc mechanism 2, the piston rod of the external tooth cylinder 243 of the external tooth ring assembly 24 extends, the movable external tooth 242 is lifted, and when the movable external tooth 242 is lifted, the round table portion at the top end of the movable external tooth 242 is contacted with the fixture 7 first, so that the movable external tooth 242 can smoothly slide over the edge of the fixture 7 without lifting the fixture 7, and after the movable external tooth 242 is lifted, both the movable external tooth 242 and the fixed external tooth 241 can be meshed with the fixture 7.
When the double-sided grinder is in grinding work, the piston rod of the rocker arm cylinder 44 is retracted, the pivot lug 414 and the positioning frame 413 pull the rotating shaft 412 of the rocker arm assembly 41 to rotate, the rotating shaft 412 is linked with the cantilever 42 to swing, the upper grinding disc mechanism 1 swings to the upper part of the lower grinding disc mechanism 2, when the upper grinding disc mechanism 1 is about to be aligned with the lower grinding disc mechanism 2, the edge of the positioning frame 413 contacts the top end of the buffer 46, and the buffer 46 acts and buffers the action of the rocker arm cylinder 44, so that the rocker arm mechanism 4 cannot collide rigidly. When the upper grinding disc mechanism 1 and the lower grinding disc mechanism 2 are accurately aligned, the piston rod of the positioning cylinder 451 extends out, so that the positioning pin 452 is inserted into the positioning pin hole 4531 of the positioning seat 453, thereby locking the rocker arm mechanism 4 and further locking the position of the upper grinding disc mechanism 1; if the upper grinding disc mechanism 1 and the lower grinding disc mechanism 2 are not aligned, even if the piston rod of the positioning cylinder 451 extends out, the positioning pin 452 cannot be inserted into the positioning pin hole 4531 of the positioning seat 453, and the rocker arm mechanism 4 cannot be locked; a program can be set, if the piston rod of the rocker arm cylinder 44 is fully retracted and the piston rod of the positioning cylinder 451 is fully extended, that is, it means that the positioning pin 452 has been inserted into the positioning pin hole 4531, at this time, the upper grinding disc mechanism 1 and the lower grinding disc mechanism 2 can be started, and grinding starts, otherwise, neither the upper grinding disc mechanism 1 nor the lower grinding disc mechanism 2 can be started.
After the upper millstone mechanism 1 is started, the upper millstone cylinder 113 acts to enable the upper millstone assembly 12 to descend, after the altimeter 18 contacts the reference block 25, information is fed back to the main control, the main control clears the height information of the upper millstone assembly 12 and redefines the current height as the reference height, the upper millstone cylinder 113 continues to act to enable the upper millstone assembly 12 to continue to descend, the altimeter 18 feeds back the displacement information of the upper millstone assembly 12 to the main control, and the main control can know the height of the upper millstone 123 of the upper millstone assembly 12 relative to the reference block 25; when the altimeter 18 detects that the height of the upper grinding layer 123 reaches the preset height, the main control controls the upper grinding disc cylinder 113 to stop acting, and the upper grinding disc assembly 12 stops pressing down.
When the double-sided grinder grinds, the sun gear motor 261 is started, and the sun gear reducer 262 and the sun gear transmission shaft 263 are sequentially transmitted to rotate the sun gear body 222 and the sun gear teeth 221, and at this time, the sun gear assembly 22 serves as a driving wheel in the planetary gear mechanism, so that the clamp 7 rotates around the shaft thereof. The lower grinding disc motor 211 is started and sequentially driven by the lower grinding disc speed reducer 212 and the lower grinding disc transmission shaft 213 to rotate the lower grinding disc assembly 23; the upper grinding disc motor 111 is started, and the first transmission teeth 131 of the ball hinge 13 are meshed with the second transmission teeth 125 of the flange 122, so that the upper grinding disc motor 111 can sequentially transmit through the upper grinding disc speed reducer 114, the upper grinding disc transmission shaft 112 and the ball hinge 13, and the upper grinding disc assembly 12 can rotate. The upper grinding layer 123 of the upper grinding disc assembly 12 and the lower grinding layer 232 of the lower grinding disc assembly 23 move relative to the upper and lower surfaces of the product to be ground on the clamp 7, so that the upper and lower surfaces of the product to be ground are rubbed, and grinding processing of the product is realized.
During the grinding process, the ball hinge 13 not only can drive, but also can make the upper grinding disc assembly 12 in a floating state, namely, when the upper grinding layer 123 of the upper grinding disc assembly 12 is not parallel to the lower grinding layer 232 of the lower grinding disc assembly 23, the angle of the upper grinding disc assembly 12 is changed by the outer cambered surface of the ball hinge 13 and the inner cambered surface of the flange 122, so that the angle of the lower grinding layer 232 of the lower grinding disc assembly 23 is adapted, and the upper grinding layer 123 of the upper grinding disc assembly 12 and the lower grinding layer 232 of the lower grinding disc assembly 23 are kept parallel to each other.
The foregoing examples are provided for the purpose of illustration only and are not intended to be limiting, and all equivalent changes or modifications made by the method described in the claims are intended to be included within the scope of the present invention.
