[0010] A fully automatic hole-digging method for square magnetic materials comprises the following steps: Step 1) Preliminary preparation: According to the size of the square magnetic block, adjust the height of the second guide rail seat by turning the first adjusting bolt to align the magnetic cylinder with the square magnetic block, adjust the height of the bottom plate by adjusting the screw to align the magnetic cylinder with the square magnetic block, adjust the height of the discharge platform by the second adjusting bolt to make it flush with the top surface of the bottom plate, and input the displacement of each component and the feed amount of the core drill in the control panel according to the size of the square magnetic block; Step 2) Feeding: Place two rows of square magnetic blocks on the feeding conveyor belt, and move the square magnetic blocks to the left along the feeding conveyor belt; Step 3) Material removal: The control system controls the magnetic cylinder and the push cylinder to start. At this time, the magnetic cylinder is energized to generate magnetism. The push cylinder pushes the hanging plate to move to the right along the supporting top plate, thereby driving the magnetic cylinder to move to the right. After it comes into close contact with the square magnetic material blocks on the feeding conveyor belt, the two magnetic cylinders tightly absorb the two square magnetic material blocks respectively; Step 4) Material transportation: The motor at the front end of the transmission box starts to drive the first lead screw to rotate, and the magnetic cylinder is driven to move forward with two square magnetic blocks through the jacking cylinder frame. When the square magnetic blocks completely pass through the transmission port, the motor at the front end of the transmission box is turned off, and the square magnetic blocks stop moving. Then the magnetic cylinder is powered off and turned off, and the two square magnetic blocks are placed on the bottom plate. The jacking cylinder is powered on and retracted to the initial position. The motor at the front end of the transmission box starts to reversely drive the first lead screw to rotate, and the magnetic cylinder is driven to return to the limit switch position through the jacking cylinder frame and stops. Repeat the above material collection and material transportation steps. While the magnetic cylinder moves forward, the second push plate pushes the square magnetic blocks placed in the previous round forward until the two square magnetic blocks placed for the first time reach the hole-cutting operation position on the bottom plate, and the material collection and material transportation operations are suspended; Step 5) Preparation for hole digging: Start the two clamping cylinders, extend them downward to hold the lower pressure head downward, hold the two square magnetic blocks, and clamp them tightly. Start the second motor and the oil pump. The second motor drives the core drill bit to rotate at high speed through the drill bit seat. At the same time, the oil pump drives the oil in the oil tank into the core drill bit, spraying oil while rotating to lubricate and cool it. Start the first motor to drive the second lead screw to rotate, so that the support bodies on both sides move toward the middle simultaneously along the second guide rail; Step 6) Hole drilling: The coring drills on both sides drill holes on both sides of the square magnetic material block at the same time. When the feed rate of the coring drill reaches the preset value, the first motor on one side is controlled to rotate in the opposite direction, so that the coring drill on one side retreats first, and then the coring drill on the other side continues to advance until the square magnetic material block is completely drilled through. The coring drill retreats again, and the sprayed oil falls into the oil storage tank, returns to the oil tank through the oil pipe, and enters the coring drill again after being filtered and precipitated in the oil tank, forming a cycle; Step 7) Discharging: After the coring drill bit is retracted, the clamping cylinder contracts, and the lower pressure head is reset under the action of the second reset spring, releasing the square magnetic block, and then repeating the material picking and transporting operations to push the next pair of square magnetic blocks into the hole-digging working position. At this time, the previous pair of square magnetic blocks are pushed forward. After the above steps are repeated continuously, the initial pair of square magnetic blocks are pushed to the discharging platform. At this time, the pushing cylinder is started, and a pair of square magnetic blocks are pushed to the right through the first push plate, and then the pushing cylinder drives the first push plate 46 to return to the initial position. When the next pair of square magnetic blocks are pushed to the discharging platform, the pushing cylinder is started again to push the square magnetic blocks to the right, and this process is repeated until the square magnetic blocks fill the discharging platform. The side door on the right side of the outer shell is opened, and the processed square magnetic blocks on the discharging platform are taken out, and the operation is completed.

The present invention designs a fully automatic square magnetic block hole-digging device, which can realize fully automatic hole-digging operation without manual assistance, greatly reducing labor costs and greatly improving operation accuracy, operation efficiency and yield rate; 2.

[0017] A fully automatic hole-digging method for square magnetic materials comprises the following steps: Step 1) Preliminary preparation: According to the size of the square magnetic material block 10, adjust the height of the second guide rail seat 30 by turning the first adjusting bolt 19, so that the magnetic cylinder 31 is aligned with the square magnetic material block 10, and adjust the height of the bottom plate 34 by adjusting the screw 38, so that when the square magnetic material block 10 is placed on the bottom plate 34, the height of the core drill 44 is aligned with the height of the hole in the square magnetic material block 10, and adjust the height of the discharge platform 54 by the second adjusting bolt 56 to make it flush with the top surface of the bottom plate 34, and input the displacement of each component and the feed amount of the core drill 44 in the control panel 3 according to the size of the square magnetic material block 10; Step 2) Feeding: Place two rows of square magnetic blocks 10 on the feeding conveyor belt 9, and move the square magnetic blocks 10 to the left along the feeding conveyor belt 9. The side limit plate 12 can prevent the square magnetic blocks 10 from falling and deviating; the top limit plate 13 can prevent the square magnetic blocks 10 of different heights from mixing in; Step 3) Material collection: First, adjust the horizontal position of the magnetic cylinder 31 by rotating the adjustment knob 28, so that the magnetic cylinder 31 is facing the square magnetic material block 10. The magnetic cylinder 31 can be reset by the first reset spring 29. The control system controls the magnetic cylinder 31 and the push cylinder to start. At this time, the magnetic cylinder 31 is energized to generate magnetism. The push cylinder pushes the hanging plate 24 to move to the right along the supporting top plate 18, thereby driving the magnetic cylinder 31 to move to the right. After coming into close contact with the square magnetic material block 10 on the feeding conveyor belt 9, the two magnetic cylinders 31 tightly absorb the two square magnetic material blocks 10 respectively, and the limit plate 32 can prevent the square magnetic material block 10 from deviating. At the same time, the laser displacement sensor 15 monitors the posture of the magnetic cylinder 31 sucking the square magnetic material block 10 in real time. If a square magnetic material block 10 deviates, the laser displacement sensor 15 recognizes it and feeds back to the control system to remind the operator to correct it; Step 4) Material transportation: The motor at the front end of the transmission box 16 is started, driving the first lead screw 33 to rotate, and the magnetic cylinder 31 is driven to move forward with the two square magnetic blocks 10 through the push cylinder frame 17. When the square magnetic blocks 10 completely pass through the transmission port 21, the motor at the front end of the transmission box 16 is turned off, the square magnetic blocks 10 stop moving, and then the magnetic cylinder 31 is powered off and closed, and the two square magnetic blocks 10 are placed on the bottom plate 34. The push cylinder is powered on and retracted to the initial position, and the motor at the front end of the transmission box 16 is started. The first lead screw 33 is driven in reverse to rotate, and the magnetic cylinder 31 is driven to retreat to the position of the limit switch 20 through the jacking cylinder frame 17, and the above-mentioned material taking and material transporting steps are repeated. While the magnetic cylinder 31 moves forward, the second push plate 53 pushes the square magnetic material blocks 10 placed in the previous round to move forward until the two square magnetic material blocks 10 placed for the first time reach the hole-digging operation position on the bottom plate 34, and the material taking and material transporting operations are suspended. At this time, the core drill bits 44 on both sides are facing the middle position of the two square magnetic material blocks 10; Step 5) Preparation for hole digging: Start the two clamping cylinders 37, extend downward to support the lower pressure head 55 to move downward, support the two square magnetic blocks 10, and clamp them tightly, start the second motor 42 and the oil pump, the second motor 42 drives the core drill 44 to rotate at high speed through the drill seat 43, and at the same time the oil pump drives the oil in the oil tank 6 to enter the core drill 44, and spray oil while rotating to lubricate and cool it, start the first motor 39, drive the second lead screw 50 to rotate, so that the support bodies 40 on both sides move toward the middle simultaneously along the second guide rail 41; Step 6) Hole drilling: The coring drill bits 44 on both sides drill holes on both sides of the square magnetic material block 10 at the same time. Taking the thickness of the square magnetic material block 10 as 15 mm as an example, when the feed amount of the coring drill bits 44 on both sides reaches the preset 7 mm, there is a remaining thickness of 1 mm that has not been drilled. At this time, the first motor 39 on one side is controlled to rotate in the opposite direction, so that the coring drill bit 44 on one side retreats first, and then the coring drill bit 44 on the other side continues to advance until the square magnetic material block 10 is completely drilled through. The coring drill bit 44 retreats again, and the sprayed oil falls into the oil storage tank 51, returns to the oil tank 6 through the oil pipe, and enters the coring drill bit 44 again after being filtered and precipitated in the oil tank 6, forming a cycle; Step 7) Discharging: After the core drill 44 is retracted, the clamping cylinder 37 contracts, and the lower pressure head 55 is reset under the action of the second reset spring 54, releasing the square magnetic block 10, and then repeating the material collection and transportation operations to push the next pair of square magnetic blocks 10 into the hole-digging working position. At this time, the previous pair of square magnetic blocks 10 are pushed forward. After the above steps are repeated continuously, the initial pair of square magnetic blocks 10 are pushed to the discharging platform 45. At this time, the pushing cylinder 47 is started, and the first push plate 46 is used to push the pair of square magnetic blocks 10 to move to the right, and then the pushing cylinder 47 drives the first push plate 46 to return to the initial position. When the next pair of square magnetic blocks 10 are pushed to the discharging platform 45, the pushing cylinder 47 is started again to push the square magnetic blocks 10 to move right, and this process is repeated until the square magnetic blocks 10 fill the discharging platform 45, then the side door 5 on the right side of the outer shell 2 is opened, and the square magnetic blocks 10 processed on the discharging platform 45 are taken out, and the operation is completed.

[0018] When the hole is being dug, the core drill 44 rotates and sprays oil, which may cause oil splashing. At this time, the control system controls the closing cylinder 48 to start contraction, driving the closing door 49 to descend, closing the transmission port 21, and at the same time, the sliding door 5 is opened to prevent the oil from splashing outside. When the parts in the front cavity need to be repaired and replaced, the sliding door 5 and the side doors 4 on both sides are opened to facilitate the repair.

[0019] When it is necessary to perform hole boring operations on square magnetic blocks of different sizes, the height of the second guide rail seat 30 is adjusted by rotating the first adjusting bolt 19 so that the magnetic cylinder 31 is aligned with the corresponding position in the middle of the square magnetic block 10, and the bottom of the square magnetic block 10 matches the different heights of the bottom plate 34. The height of the bottom plate 34 is adjusted by adjusting the screw 38 so that when the square magnetic block 10 is placed on the bottom plate 34, the height of the coring drill bit 44 is aligned with the height of the hole bored in the square magnetic block 10. The height of the discharge platform 54 is adjusted by the second adjusting bolt 56 so that it is flush with the top surface of the bottom plate 34. The displacement of each component and the feed amount of the coring drill bit 44 are input into the control panel 3 according to the size of the square magnetic block 10.

A method for fully automatic hole punching of square magnetic materials using the fully automatic hole punching device for square magnetic materials according to claim 1, characterized in that: The steps include: Step 1) Preliminary preparation: According to the size of the square magnetic material block (10), the height of the second guide rail seat (30) is adjusted by rotating the first adjusting bolt (19) so that the magnetic cylinder (31) is aligned with the square magnetic material block (10); the height of the bottom plate (34) is adjusted by adjusting the screw (38) so that the magnetic cylinder (31) is aligned with the square magnetic material block (10); the height of the discharge platform (54) is adjusted by the second adjusting bolt (56) so that it is flush with the top surface of the bottom plate (34); and the displacement of each component and the feed amount of the core drill (44) are input into the control panel (3) according to the size of the square magnetic material block (10); Step 2) feeding: placing two rows of square magnetic material blocks (10) on the feeding conveyor belt (9), and moving the square magnetic material blocks (10) to the left along the feeding conveyor belt (9); Step 3) Retrieving materials: The control system controls the magnetic cylinder (31) and the push cylinder to start. At this time, the magnetic cylinder (31) is energized to generate magnetism, and the push cylinder pushes the hanging plate (24) to move rightward along the supporting top plate (18), thereby driving the magnetic cylinder (31) to move rightward. After the magnetic cylinder (31) comes into close contact with the square magnetic material blocks (10) on the feeding conveyor belt (9), the two magnetic cylinders (31) respectively tightly absorb the two square magnetic material blocks (10); Step 4) Material transportation: The motor at the front end of the transmission box (16) is started to drive the first lead screw (33) to rotate, and the magnetic cylinder (31) is driven to move forward with the two square magnetic blocks (10) through the push cylinder frame (17). When the square magnetic blocks (10) completely pass through the transmission opening (21), the motor at the front end of the transmission box (16) is turned off, the square magnetic blocks (10) stop moving, and then the magnetic cylinder (31) is powered off and turned off. The two square magnetic blocks (10) are placed on the bottom plate (34), and the push cylinder is powered on to retract and return to the initial position. At the starting position, the motor at the front end of the transmission box (16) starts to reversely drive the first lead screw (33) to rotate, and the magnetic cylinder (31) is driven to return to the limit switch (20) position through the jacking cylinder frame (17) and stops, and the above-mentioned material picking and material transporting steps are repeated. While the magnetic cylinder (31) moves forward, the second push plate (53) pushes the square magnetic material blocks (10) placed in the previous round to move forward until the two square magnetic material blocks (10) placed for the first time reach the hole-cutting operation position on the bottom plate (34), and the material picking and material transporting operations are suspended; Step 5) Preparation for hole digging: Start the two clamping cylinders (37), extend them downward to support the lower pressure head (55) and move it downward, support the two square magnetic blocks (10), and clamp them tightly, start the second motor (42) and the oil pump, the second motor (42) drives the coring drill bit (44) to rotate at high speed through the drill bit seat (43), and at the same time the oil pump drives the oil in the oil tank (6) to enter the coring drill bit (44), and sprays oil while rotating to lubricate and cool it, start the first motor (39), drive the second lead screw (50) to rotate, and make the support bodies (40) on both sides move toward the middle simultaneously along the second guide rail (41); Step 6) drilling holes: the coring drill bits (44) on both sides drill holes on both sides of the square magnetic material block (10) at the same time. When the feed rate of the coring drill bit (44) reaches a preset value, the first motor (39) on one side is controlled to rotate in the opposite direction, so that the coring drill bit (44) on one side first moves backward, and then the coring drill bit (44) on the other side continues to move forward, until the square magnetic material block (10) is completely drilled through. The coring drill bit (44) then moves backward again, and the ejected oil falls into the oil storage tank (51), returns to the oil tank (6) through the oil pipe, and enters the coring drill bit (44) again after being filtered and precipitated in the oil tank (6), thus forming a cycle. Step 7) Discharging: After the coring drill bit (44) is retracted, the clamping cylinder (37) contracts, and the lower pressure head (55) is reset under the action of the second reset spring (54), releasing the square magnetic material block (10), and then repeating the material collection and transportation operations, pushing the next pair of square magnetic material blocks (10) into the hole-digging working position, at which time the previous pair of square magnetic material blocks (10) are pushed forward, and after the above steps are repeated continuously, the first pair of square magnetic material blocks (10) are pushed onto the discharging platform (45), and at this time the pushing cylinder (47) is started, and the first pair of square magnetic material blocks (10) are pushed forward. The push plate (46) pushes a pair of square magnetic material blocks (10) to move to the right, and then the push cylinder (47) drives the first push plate (46) to return to the initial position. When the next pair of square magnetic material blocks (10) are pushed onto the discharge platform (45), the push cylinder (47) is started again to push the square magnetic material blocks (10) to move to the right. This process is repeated until the square magnetic material blocks (10) fill the discharge platform (45). Then, the side door (5) on the right side of the outer shell (2) is opened, and the processed square magnetic material blocks (10) on the discharge platform (45) are taken out, and the operation is completed.
