[0034] An electromagnet is installed on the inner wall of the storage hole 6, and the electromagnet is electrically connected to a power supply;

[0035] A second pressure sensor is installed in the storage hole 6;

[0036] The slider 4 is electrically connected to the first driving member;

[0037] A grinding device for a femoral intramedullary nail instrument kit includes a processing rod detection process unit, a processing rod processing drive unit, and a processing rod process control unit;

[0038] The processing rod detection process unit includes a processing rod aperture detection module, a polishing rod pre-calibration module, and a polishing timing module;

[0039] The processing rod processing drive unit includes a pump first motion module, a pump second motion module, a rack motion module, an endless conveyor motion module, a polishing rod motion module, and a detection rod motion module;

[0040] The rod processing process control unit includes a grinding intensity control module and a pump operation intensity control module;

[0041] The diameters of the two ends of the processed rod are inconsistent. One end has a small diameter and is shaped like a thin rod, while the other end has a large diameter and is shaped like a thick rod. There is a hole at the thick end of the processed rod.

[0042] The first embodiment is how to grind a processing rod:

[0043] In the first step, the personnel directs one end of the thin rod of the processing rod toward the storage hole 6 and places the processing rod into the storage hole 6. The personnel applies a certain amount of pressure on the processing rod to push the processing rod into the storage hole 6. This pressure application is a continuous pressure action until the processing rod is pushed into the bottom of the storage hole 6. At this time, the processing rod triggers the second pressure sensor. The second pressure sensor senses that the processing rod has reached the set position and sends a command to the rack motion module. The rack motion module drives the electromagnet to energize, and the electromagnet is energized to adsorb the processing rod. Through the dual fixation of the electromagnet and the storage hole, the processing rod can be tightly locked in the storage hole 6, ensuring that the processing rod is always in a stable state when the grinding rod 10 is grinding the processing rod;

[0044] In the second step, the rack 5 is provided with a plurality of storage holes 6, that is, a plurality of processing rods are provided. The personnel fill the storage holes 6 on the rack 5 in sequence according to the process of the first step. This step is used to place multiple processing rods that need to be polished at one time. The subsequent polishing and inspection processes do not require human supervision. The personnel can fill the processing rods on the next device, saving time and improving polishing efficiency.

[0045] After all the storage holes 6 are filled, all the second pressure sensors are activated, and the endless conveyor belt motion module is in a start-up standby state;

[0046] In the third step, the personnel input the original hole diameter value H1 on the processing rod into the system, and the processing rod diameter detection module records the input original hole diameter value on the processing rod, and inputs the hole diameter value H2 after grinding. The processing rod diameter detection module compares H1 and H2. H1 is greater than H2. The processing rod diameter detection module is connected to the camera component. After the grinding head 16 completes the grinding, the camera component detects the hole diameter of the processing rod after the processing, and records the hole diameter value at this time as H3. The processing rod diameter detection module compares H3 with H2. If H3 is consistent with H2, it means that the first process of grinding the hole diameter is completed. If H3 is inconsistent with H2, the grinding head 16 grinds the processing rod hole again.

[0047] In the fourth step, the polishing rod motion module drives the polishing rod 10 to extend and drives the polishing head 16 to move toward the processing rod. The polishing head 16 approaches the processing rod and polishes the processing rod. After the polishing head 16 completes polishing of one processing rod, the polishing rod motion module drives the polishing rod 10 to retract and drives the polishing head 16 to reset. The annular conveyor belt motion module drives the annular conveyor belt 17 to operate, remove the completed processing rod, and move the adjacent unpolished processing rod to the polishing position to facilitate the subsequent polishing process.

[0048] The second embodiment is a detailed process of polishing the processing rod:

[0049] Step 5: Set the first polished rod as N1, the nth polished rod as Nn, and set i rods between the polishing head 16 and the detection head 11, with one rod position being one unit.

[0050] That is, when the first processing rod is polished, the annular conveyor belt 17 drives the processing rod to move one unit. After the first processing rod moves (i+1) units, the first processed processing rod is just located at the position corresponding to the detection head 11. At this time, the detection rod motion module drives the detection rod 9 to extend. The extension of the detection rod 9 drives the detection head 11 to extend. The extension of the detection head 11 drives it to gradually extend into the hole of the processing rod. When the detection head 11 moves, it drives the induction coil 12 to move. The induction coil 12 moves to contact with the processing rod. It is set that M induction coils 12 are provided from the front end of the detection head 11 to the back, divided into M1-M5. The diameter of the M1th induction coil 12 is the smallest, and the diameter of the M5th induction coil 12 is the largest. From the M1th induction coil 12 to the M5th induction coil 12, the diameter of the induction coil 12 increases successively, indicating that the diameter of the processing rod hole contacted with the corresponding induction coil 12 is larger. In the third step of the first embodiment, The staff inputs the hole diameter value H2 after grinding. H2 is divided into H21-H25. H21 has the smallest hole diameter length value, and H25 has the largest hole diameter length value. M1-M5 correspond to H21-H25 one by one. By monitoring the status of the induction coil 12, it is determined which induction coil 12 is in contact with the processing rod. If the induction coil 12 in contact is not the induction coil 12 that matches the set hole diameter length value, the processing rod is determined to be unqualified. At the same time, the electromagnetic valve on the induction coil 12 in contact with the processing rod is opened for 1 second, and the paint flows out and stains the surface of the processing rod. When the staff removes the processing rod later, they only need to identify whether it is stained with paint to distinguish between qualified processing rods and unqualified processing rods. If the induction coil 12 in contact matches the set hole diameter length value, the processing rod is determined to be qualified. This cooperates with the processing rod aperture detection module in the first embodiment to form a multiple detection process to maximize the guarantee of grinding accuracy.

[0051] The grinding timing module sets the grinding head 16 to grind the processing rod for K time, and after grinding for K time, the holes of the processing rod are inspected;

[0052] K is divided into K1-K5, K1 has the shortest duration and K5 has the longest duration. K1-K5 correspond to H21-H25 one by one.

[0053] Step 6: Before the grinding head 16 grinds the first processing rod, the grinding rod pre-calibration module drives the grinding rod 10 to extend and moves the grinding head 16 close to the processing rod. The grinding head 16 contacts the processing rod but does not grind. At this time, the camera assembly detects whether the grinding head 16 is at the center of the processing rod. If the grinding head 16 is at the center of the processing rod, grinding begins directly.

[0054] If the grinding head 16 is not at the center of the processing rod, the camera assembly detects and determines whether the grinding head 16 is higher or lower than the center of the processing rod. If the grinding head 16 is higher than the center of the processing rod, the rack motion module drives the slider 4 to drive the rack 5 to slide upward on the lifting rail 13. The rack 5 moves upward and drives the processing rod upward until the grinding head 16 is aligned with the center of the processing rod. If the grinding head 16 is lower than the center of the processing rod, the rack motion module drives the slider 4 to drive the rack 5 to slide downward on the lifting rail 13 until the grinding head 16 is aligned with the center of the processing rod.

[0055] By setting up a pre-calibration process, batch grinding errors can be avoided during the grinding process of the processed rods;

[0056] In the seventh step, the first motion module of the pump drives the pump to collect the debris on the surface of the grinding head 16 through the dust suction hole 15;

[0057] The second motion module of the pump drives the pump to discharge the collected debris to the surface of the grinding head 16 through the dust suction hole 15;

[0058] The pump operation intensity control module sets the pump operation intensity to F, with a total of 5 levels from F1 to F5. F1 indicates the lowest pump operation intensity, and F5 indicates the highest pump operation intensity. F1-F5 correspond to H21-H25 one by one. As the diameter of the machining rod to be polished increases, the generated debris increases, that is, the pump operation intensity increases, ensuring that the waste debris generated by polishing can be collected in time to improve the utilization rate of debris. This pump operation intensity control only applies to the first motion module of the pump, and the power of the second motion module of the pump is constant.

[0059] The grinding intensity control module sets the rotation speed of the grinding head 16 to be constant. When the hole processing level of the processing rod is H24 and H25, the first motion module of the pump machine is not running. Then, when the grinding starts, the second motion module of the pump machine starts to run to discharge the debris. A layer of debris adheres to the surface of the grinding head 16. The debris is used to increase the grinding intensity of the grinding head 16 and reduce the wear of the grinding head 16. When the grinding time reaches K / 2, the second motion module of the pump machine is turned off, and the first motion module of the pump machine is operated to collect the debris.

[0060] During the grinding period of H21-H23, if the debris is not collected in time, there will be scratches on the inner wall of the rod hole during the grinding process;

[0061] Grinding to K / 2 time length and then collecting debris, ensure that the surface of the grinding head 16 is clean, the inner wall of the processing rod hole is finely ground, and the inner wall of the processing rod hole is ground out relatively smooth.
