Description

Technical Field

[0001] The invention relates to the technical field of grinder equipment, in particular to a medical nickel-titanium material grinder and a processing method thereof. Background Art

[0002] As a shape memory alloy, nickel-titanium alloy has been widely used in the medical field due to its unique superelasticity and shape memory properties, especially in orthopedic medical devices. For example, bone plates, stents and other devices made of nickel-titanium materials can adapt to the complex anatomical structure of the human body and show excellent performance during surgery. However, in order to ensure the safety and functionality of these medical devices, their surfaces must be precisely polished. Unpolished nickel-titanium materials may have burrs, rough surfaces or processing marks, which not only affect the performance of the device, but may also cause potential harm to patients. Therefore, efficient and high-precision polishing of medical nickel-titanium materials has become a key link in the production process.

[0003] In the prior art, a cylinder-driven grinder is usually used to grind nickel-titanium alloy bone plates. The grinding head of this type of equipment is generally fixedly mounted on the output end of the cylinder through a connector, so that the height of the grinding head can be adjusted by the cylinder to meet the processing requirements of materials of different thicknesses. However, for some bone plates with complex designs, such as products with micropores or porous structures, the existing grinding methods have obvious shortcomings. Due to the limitations of the grinding head size and the cylinder height adjustment range, it is difficult to accurately insert the grinding head into tiny holes or porous structures for fine processing. This results in some areas relying on manual grinding to achieve the required precision requirements. However, manual grinding is not only inefficient, but also difficult to ensure consistency, which significantly reduces the overall processing efficiency and increases production costs.

[0037] By controlling the cross slide 2 to cooperate with the cylinder 3, bone plates of different thicknesses can be polished, and different positions can also be polished, which improves the convenience of polishing. When it is necessary to finely process the tiny holes or porous structures of the bone plates, first remove the original polishing head 8, and then install the fine polishing head 8 at the bottom of the rotating shaft 7. At this time, the output end of the electric cylinder 5 can be extended by controlling the output end of the electric cylinder 5. Since one end of the connecting frame 6 is fixedly connected to the output end of the electric cylinder 5, the sliding pin 17 fixedly sleeved on the other end of the connecting frame 6 slides and is engaged in the annular groove 18 provided on the rotating shaft 7, thereby pushing the rotating shaft 7.

[0039] When the fine grinding head 8 needs to be replaced, first pull the limit pins 27 on both sides of the threaded sleeve 19 in reverse order to make the limit pins 27 drive the spring 26 to stretch, so that the limit pins 27 are pulled out of the recessed holes 24. At this time, the original grinding head 8 can be disassembled by twisting the connecting column 23, and then the connecting column 23 of the fine grinding head 8 is installed in the threaded sleeve 19 through a threaded connection. Then, the limit pins 27 are loosened to be inserted into the recessed holes 24 opened on the connecting column 23, thereby further limiting the installed grinding head 8. The above operation facilitates the replacement of the grinding head 8 and improves the processing efficiency.

[0040] Embodiment 4: On the basis of embodiment 3, one side of the clamping block 12 is fixedly connected to the anti-skid soft block 13. The anti-skid soft block 13 increases the friction with the workpiece on the one hand and prevents the workpiece from being damaged on the other hand. The other side of the clamping block 12 is fixedly connected to one end of the driven rod 28. The other end of the driven rod 28 is meshed with the lower side of the half gear 30 through the tooth groove 29 provided. The upper side of the half gear 30 is meshed with the tooth groove 29 provided at one end of the driving rod 31 for transmission. The half gear 30 is used for the transmission of the driving rod 31 and the driven rod 28. The other end of the driving rod 31 is slidably connected between the inclined surface 32 provided and the inclined surface 32 provided at one end of the pressure rod 33. One end of the driving rod 31 and one end of the pressure rod 33 are squeezed and slid by the inclined surface 32 provided. The other end of the pressure rod 33 is fixedly installed with a limited bearing 34. The limited bearing 34 adopts an installation method in which the inner ring rotates and the outer ring is fixed. The limited bearing 34 The inner ring surface is fixedly connected to the bottom end of the threaded rod 35, so that when the threaded rod 35 rotates, it will not drive the pressure rod 33 to rotate, but only drive the pressure rod 33 to move up and down. The threaded rod 35 is sleeved in the support frame 36, and a hand wheel is fixedly connected to the top of the threaded rod 35. The support frame 36 limits the threaded rod 35. The support frame 36 is fixedly connected to one side of the fixed block 37, and the other side of the fixed block 37 is fixedly connected to the upper surface of the processing table 11. A round block 38 is fixedly connected in the fixed block 37, and the round block 38 is slidably connected to the inner ring surface of the half gear 30. The round block 38 limits the half gear 30. The driving rod 31 and the driven rod 28 are both slidably installed in the fixed block 37. A pin is fixedly connected in the fixed block 37. The outer rings of the driving rod 31 and the driven rod 28 are provided with sliding grooves, and the sliding grooves are slidably connected to the pins, thereby improving the stability of the driving rod 31 and the driven rod 28 sliding in the fixed block 37.

[0041] Before grinding the bone plate, place the workpiece in the middle of the upper surface of the processing table 11, and twist the hand wheel fixedly connected to the top of the threaded rod 35 to drive the threaded rod 35 to rotate. Due to the threaded connection between the threaded rod 35 and the support frame 36, the threaded rod 35 moves vertically downward, and the bottom of the threaded rod 35 is fixedly sleeved on the inner ring surface of the limit bearing 34. The limit bearing 34 adopts an installation method in which the inner ring rotates and the outer ring is fixed. Therefore, when the threaded rod 35 moves downward, the pressure rod 33 is driven downward through the connection of the limit bearing 34. The pressure rod 33 then squeezes the inclined surface 32 opened at its bottom end and the inclined surface 32 opened at one end of the driving rod 31, thereby pushing the driving rod 31 to slide into the fixed block 37. The other end of the driving rod 31 is connected to the semi-toothed groove 29 by the tooth groove 29 The upper side of the wheel 30 is meshed for transmission, and the half gear 30 rotates under the limit of the round block 38, so that the lower side of the half gear 30 is meshed with the tooth groove 29 opened at one end of the driven rod 28, and then drives the driven rod 28 to slide to the outside of the fixed block 37, and then drives the clamping block 12 to move. There are four clamping blocks 12, and the four clamping blocks 12 are arranged in a square, so that the four clamping blocks 12 move to the four corners of the bone plate until the anti-slip soft block 13 abuts against the side wall of the bone plate, and finally fixes the bone plate on the processing table 11, which is convenient for subsequent grinding. By adjusting the depth of the threaded rod 35 screwed into the support frame 36, it is convenient to adapt to bone plates of different sizes, thereby expanding the scope of use and improving the practicality of the entire device. When the bone plate needs to be disassembled, the threaded rod 35 can be twisted in the opposite direction.

[0042] In actual use: S1, place the bone plate to be polished on the upper surface of the processing table 11, and drive the threaded rod 35 to rotate by twisting the hand wheel, so that the threaded rod 35 moves vertically downward, and the threaded rod 35 drives the pressure rod 33 to move downward through the limit bearing 34, and the pressure rod 33 pushes the driving rod 31 to slide through the inclined surface 32, and the driving rod 31 is meshed with the half gear 30 through the tooth groove 29, and the half gear 30 drives the driven rod 28 to slide, and the driven rod 28 pushes the clamping block 12 to move toward the four corners of the bone plate until the anti-skid soft block 13 abuts against the side wall of the bone plate to fix the bone plate;

[0043] S2, the output end of the control cylinder 3 extends out, driving the fixed frame 4 to move downward, thereby indirectly driving the grinding head 8 to approach the surface of the bone plate, and the driving gear 9 is driven by the motor 14 to rotate, and the driving gear 9 is meshed with the driven gear 10 for transmission, so that the rotating shaft 7 drives the grinding head 8 to rotate, and the surface of the bone plate is polished, and the movement of the cross slide 2 is coordinated to facilitate the grinding head 8 to polish different positions;

[0044] S3. When fine grinding is required, first remove the original grinding head 8, pull the limit pin 27, twist the connecting column 23 to remove it, then install the connecting column 23 of the fine grinding head 8, loosen the limit pin 27 to make it inserted into the recessed hole 24, and complete the replacement; extend the output end of the electric cylinder 5, push the connecting frame 6 to drive the rotating shaft 7 to move downward, and the rotating shaft 7 drives the fine grinding head 8 to extend into the tiny holes or porous structures for fine grinding, and finally realize the comprehensive grinding operation of the bone plate.
