The internal thread of the screw sleeve 17 is penetrated by a screw rod 2 16. The end of the screw rod 2 16 away from the main body 1 of the coring and repairing device is transmission-connected to a motor 1 fixed on the inner wall of the shell 2. The motor 1 is a forward and reverse stepping motor. A stopper 21 with a diameter larger than the inner diameter of the screw sleeve 17 is fixed to the other end of the screw rod 2 16. The interior of the shell 2 is slidably connected to a receiving box 18 located below the main body 1 of the coring and repairing device. When the main body 1 of the core taking and core repairing device is idle, the motor 1 can be used to drive the screw rod 2 16 to rotate, and the screw rod 2 16 and the screw thread 17 can be matched to drive the screw sleeve 17 and the loading block 10 to move. At this time, the displaced loading block 10 will drive the mounting plate 12 and the loading block 2 11 to move, and drive the main body 1 of the core taking and core repairing device to move. When the displaced main body 1 of the core taking and core repairing device enters the interior of the shell 2, the displaced loading block 2 11 will close the opening of the shell 2. At this time, the idle main body 1 of the core taking and core repairing device is temporarily stored in the interior of the shell 2. When the displaced loading block When the first threaded column 10 contacts the second threaded column 14, the second threaded column 14 will pass through the connecting hole and enter the interior of the driving sleeve 13. The second threaded column 14 entering the interior of the driving sleeve 13 will drive the driving sleeve 13 and the mounting plate 12 to rotate, thereby driving the coring and core repairing equipment body 1 to rotate. When the rotating coring and core repairing equipment body 1 rotates, the slag inside the coring and core repairing equipment body 1 will fall into the interior of the receiving box 18 along with the rotating coring and core repairing equipment body 1 and be received by the receiving box 18, thereby preventing the fallen slag from scattering everywhere and making it convenient for users to recycle the slag, which is easy to use.
[0035] The inner walls at both ends of the bottom of the shell 2 are provided with sliding grooves, and the inside of the sliding grooves is slidably connected to a sliding block fixed to the bottom of the receiving box 18. Through the sliding cooperation between the sliding grooves and the sliding blocks, the stability of the receiving box 18 can be improved, and the receiving box 18 can be prevented from sliding inside the shell 2.
[0036] A guide groove is provided on the inner wall of the top of the shell 2, and a guide block sliding inside the guide groove is fixed on the top of the loading block 10. Through the sliding cooperation between the guide groove and the guide block, the displacement of the loading block 10 can be limited to prevent the loading block 10 from being offset during the displacement process.
[0037] A fixing block is fixed on the side of the loading block 2 11 away from the main body 1 of the coring and core repairing equipment. A plurality of universal wheels 20 whose bottoms are at the same level as the bottom of the shell 2 are fixed at the bottom of the fixing block. The universal wheels 20 can be used for flexible displacement of the loading block 2 11 .
[0038] A slot is provided at the bottom of the loading block 10 , and the receiving box 18 slides in cooperation with the slot. The slot facilitates the displacement of the loading block 10 and prevents the receiving box 18 from interfering with the displacement of the loading block 10 .
[0039] One end of screw rod 1 is transmission connected to motor 2 fixed on the inner wall of one side of the adjacent mounting block 4. Motor 2 is a forward and reverse stepping motor. The other end of screw rod 1 is rotationally connected to the inner wall on the other side of the adjacent mounting block 4. The operation of motor 2 can drive screw rod 1 to rotate.
[0040] The length of the shell 2, the screw rod 16 and the receiving box 18 is greater than the length of the core removal and repairing equipment body 1. A movable door 19 is hinged on the outside of the shell 2. By opening the movable door 19, the user can conveniently inspect and maintain the components inside the shell 2.
[0041] Working principle: After the core making is completed, the upper and lower molds of the core box are opened, and the lower mold is moved to the back through the shuttle mechanism. The coring and core repairing device in the front is synchronously moved to the original lower mold position, and then the ejector mechanism of the core making equipment moves upward. After contacting the top column of the coring and core repairing equipment, the coring and core repairing equipment moves upward, and the top core plate also moves upward until the limit block contacts the upper mold of the core box. At this time, the spring on the top core plate guide column has been compressed, and then the top core plate of the upper core box moves downward, and the coring and core repairing equipment moves downward synchronously to take the sand core out of the upper core box. The core repairing plate installed on the top core plate completes the core repairing function at the moment when the spring on the top core plate guide column is released. Through the operation of motor 2, the screw rod 1 is driven to rotate, which drives the sliding block 22 to move, and drives the hydraulic cylinder 6 to The displacement drives the slider 5 to be displaced, drives the bearing block 7 and the main body 1 of the coring and core repairing equipment to be displaced, and the horizontal position of the main body 1 of the coring and core repairing equipment can be adjusted at this time. The operation of the hydraulic cylinder 6 can drive the slider 5 to be vertically displaced, drives the bearing block 7 and the main body 1 of the coring and core repairing equipment to be vertically displaced, and the vertical position of the main body 1 of the coring and core repairing equipment can be adjusted at this time. The angle of the main body 1 of the coring and core repairing equipment can be adjusted by operating the hydraulic cylinder 6 at one end of the main body 1 of the coring and core repairing equipment. When the main body 1 of the coring and core repairing equipment needs to be disassembled from the device, the threaded sleeve 9 can be rotated, and the threaded sleeve 9 can be driven to be vertically displaced by the threaded cooperation of the threaded sleeve 9 and the threaded column 8. When the threaded sleeve 9 is separated from the threaded column 8 After the outside of the core taking and core repairing device, the main body 1 of the core taking and core repairing device can be pulled to drive the main body 1 of the core taking and core repairing device to move vertically. When the perforation on the main body of the core taking and core repairing device 1 is separated from the threaded column 18, the main body 1 of the core repairing device is detached from the device. When the main body of the core taking and core repairing device 1 is idle, the motor 1 can be operated to drive the screw rod 2 16 to rotate. The rotation of the screw rod 2 16 and the threaded cooperation of the screw sleeve 17 drive the screw sleeve 17 and the loading block 10 to move. At this time, the displaced loading block 10 will drive the mounting plate 12 and the loading block 2 11 to move, and drive the main body 1 of the core taking and core repairing device to move. When the displaced main body 1 of the core taking and core repairing device enters the interior of the shell 2, the displaced loading block 2 11 will close the shell The opening of the body 2 is formed, and the idle coring and core repairing equipment body 1 is temporarily stored inside the shell body 2. When the displaced loading block 10 contacts the threaded column 2, the threaded column 2 14 will pass through the connecting hole and enter the interior of the driving sleeve 13. At this time, the threaded column 2 14 entering the interior of the driving sleeve 13 will drive the driving sleeve 13 and the mounting plate 12 to rotate, thereby driving the coring and core repairing equipment body 1 to rotate. When the rotating coring and core repairing equipment body 1 rotates, the slag inside the coring and core repairing equipment body 1 will fall into the interior of the receiving box 18 along with the rotating coring and core repairing equipment body 1 and be received by the receiving box 18, thereby avoiding the fallen slag from being scattered everywhere and being convenient for users to recycle the slag, which is easy to use.
