Description

Technical Field

[0001] This utility model relates to the field of dental drill bit testing technology, and in particular to a dental drill bit performance testing device doped with copper hydroxyapatite. Background Technology

[0002] In dental surgery, the drill bit is a key treatment tool. Its performance stability and shape regularity are directly related to the safety and treatment effect of the operation. However, during long-term use and wear, the irregular shape of the drill bit may lead to operational instability. Furthermore, the irregular shape of the drill bit may generate vibration when rotating, which may affect the accuracy of the operation and may even cause unnecessary damage to the patient's teeth.

[0003] Therefore, it is necessary to design a dental drill performance testing device that can detect the regularity of drill bit shape and avoid operational instability or tooth damage caused by irregular shape. Summary of the Invention

[0004] To overcome the drawbacks of irregular shapes in dental drills that can lead to operational instability during prolonged use and wear, and the vibrations that can affect surgical precision and even cause unnecessary damage to the patient's teeth, this invention provides a copper-doped hydroxyapatite dental drill performance testing device that can detect the regularity of drill shape and avoid operational instability or tooth damage caused by irregular shape.

[0005] The technical implementation scheme of this utility model is as follows: a dental drill bit performance testing device with copper doped hydroxyapatite, comprising a base frame, a first motor, a one-way lead screw, guide posts, a top plate, a rotating assembly, a clamping assembly, and a testing assembly. The first motor is connected to the upper left part of the base frame, and the one-way lead screw is connected to the output shaft of the first motor. Guide posts are connected to the upper sides of the front and rear parts and the upper right part of the base frame. The top plate is slidably connected between the guide posts. The top plate is threadedly connected to the one-way lead screw. The top plate is provided with a rotating assembly that can simulate the rotation of a dental drill bit. The rotating assembly is provided with a clamping assembly that can clamp and fix the dental drill bit. The base frame is provided with a testing assembly that can test the stability of the dental drill bit.

[0006] Optionally, the bottom of both the left and right sides of the base frame is provided with two pads, one at the front and one at the back.

[0007] Optionally, the rotating assembly includes a second motor and a rotating plate, with the second motor connected to the upper side of the center of the top plate and the rotating plate connected to the output shaft of the second motor.

[0008] Optionally, it also includes a clamping assembly, which includes a bidirectional lead screw, a third motor, a sleeve, a clamping frame, and a first spring. The bidirectional lead screw is rotatably connected to the lower part of the rotating plate, and the third motor is connected to the right side of the rotating plate. The output shaft of the third motor is connected to the bidirectional lead screw. Sleeves are threadedly connected to both the left and right sides of the bidirectional lead screw. The sleeves are in contact with the lower side of the rotating plate. The clamping frame is slidably connected to the lower part of each sleeve. A first spring is connected between the clamping frame and the adjacent sleeve.

[0009] Optionally, it also includes a detection component, which includes a fixed frame, a sliding frame, a contact wheel, a second spring, and a pressure sensing ring. Fixed frames are connected to the upper sides of both the left and right sides of the base frame. Sliding frames are slidably connected to the upper parts of the fixed frames. Contact wheels are rotatably connected to the adjacent parts of the sliding frames. Pressure sensing rings are connected to the adjacent sides of the fixed frames.

[0010] Optionally, it also includes a placement frame and a simulation block, with the placement frame connected to the upper side of the middle of the base frame, and the simulation block snapped into the placement frame.

[0011] The present invention has the following advantages: 1. The present invention detects the pressure received by the drill bit during the rotation process through the pressure sensing ring. When the shape of the drill bit is irregular, the pressure value detected by the pressure sensing ring will be different. The greater the change in the pressure value detected by the pressure sensing ring, the more unstable the use of the drill bit will be. This achieves the effect of detecting the regularity of the drill bit shape and avoiding the instability of operation or damage to teeth caused by irregular shape.

[0012] 2. This utility model uses the downward movement of the drill bit to drive the contact wheel to rotate, causing the drill bit to drill into the simulated block. The simulated block simulates the material of teeth, and the wear resistance is tested by drilling into the simulated block. This achieves the effect of testing the wear resistance of the drill bit by drilling into the tooth material, which is convenient for detecting the wear of the drill bit in actual operation.

It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0020] A device for testing the performance of copper-doped hydroxyapatite dental drill bits, such as... Figures 1-5As shown, it includes a base frame 1, a first motor 2, a one-way lead screw 3, guide posts 4, a top plate 5, a placement frame 18, a simulation block 19, a rotating assembly, a clamping assembly, and a detection assembly. The base frame 1 has two feet on its left and right sides for support. The first motor 2 is connected to the upper left of the base frame 1, and the one-way lead screw 3 is connected to the output shaft of the first motor 2. Guide posts 4 are connected to the upper sides of the front and rear sections and the upper right side of the base frame 1. The top plate 5 is slidably connected between the guide posts 4. A single-direction lead screw 3 is threadedly connected to the base frame 1. A placement frame 18 is connected to the upper middle part of the base frame 1. A simulation block 19 is snapped into the placement frame 18. A rotating assembly is provided on the top plate 5. The rotating assembly includes a second motor 6 and a rotating plate 7. The second motor 6 is connected to the upper middle part of the top plate 5. The rotating plate 7 is connected to the output shaft of the second motor 6. A clamping assembly is provided on the rotating assembly. The clamping assembly includes a double-direction lead screw 8, a third motor 9, a sleeve 10, a clamping frame 12, and a first spring 11. The rotating plate... The lower part of the rotating plate 7 is rotatably connected to a bidirectional lead screw 8. The right side of the rotating plate 7 is connected to a third motor 9. The output shaft of the third motor 9 is connected to the bidirectional lead screw 8. Both the left and right sides of the bidirectional lead screw 8 are threadedly connected to sleeves 10. Both sleeves 10 are in contact with the lower side of the rotating plate 7. Both sleeves 10 are slidably connected to a clamping frame 12. Both clamping frames 12 and adjacent sleeves 10 are connected to a first spring 11. The base frame 1 is equipped with a detection assembly, which includes a fixed frame 13, a sliding frame 14, a contact wheel 15, a second spring 16, and a pressure sensing ring 17. Both the left and right sides of the base frame 1 are connected to fixed frames 13. Both fixed frames 13 are slidably connected to sliding frames 14. Both sliding frames 14 are rotatably connected to contact wheels 15 on their adjacent sides. Both fixed frames 13 are connected to pressure sensing rings 17 on their adjacent sides. Both sliding frames 14 pass through adjacent pressure sensing rings 17. Both pressure sensing rings 17 and adjacent sliding frames 14 are sleeved with a second spring 16.

[0021] When using this device, first place the base frame 1 in the dental drill performance testing area, then place the drill bit in the middle of the rotating plate 7, so that the drill bit is positioned between the clamping frames 12. Then start the third motor 9, which drives the bidirectional lead screw 8 to rotate, causing the sleeve 10 to move under the action of the thread, so that the clamping frames 12 move closer to each other. When the clamping frames 12 contact the drill bit and continue to move, they will move on the sleeve 10, and the first spring 11 will be compressed and contracted. Under the action of the first spring 11, the clamping frames 12 will be pressed against the drill bit. After clamping and fixing, turn off the third motor 9, and then start the second motor 6, which drives the rotating plate 7 to rotate, so that the drill bit rotates. At the same time, start the first motor 2, which drives the unidirectional lead screw 3 to rotate, so that the top plate 5 moves downward along the guide post 4 under the action of the thread, so that the drill bit contacts the compression contact wheel 15. The sliding frame 14 will move on the fixed frame 13, and the second spring 16 will be compressed and contracted. When the drill bit moves downward... The contact wheel 15 is rotated, causing the drill bit to drill into the simulation block 19. The simulation block 19 simulates the material of teeth. The wear resistance is tested by the drill bit drilling into the simulation block 19. This allows for the testing of the drill bit's wear resistance by drilling into the tooth material, facilitating the detection of the drill bit's wear during actual operation. During the rotation of the drill bit, the pressure is detected by the pressure sensing ring 17. When the drill bit shape is irregular, the pressure value detected by the pressure sensing ring 17 will be different. The greater the change between the two pressure values ​​detected by the pressure sensing ring 17, the more unstable the use of the drill bit will be. This allows for the detection of the drill bit's shape regularity, avoiding operational instability or damage to teeth due to irregular shape. After the test is completed, the first motor 2 is started in reverse, driving the one-way lead screw 3 to rotate, causing the top plate 5 to move upward under the action of the thread, so that the drill bit no longer contacts the pressure contact wheel 15. The second spring 16 returns to its original state, driving the sliding frame 14 to move and reset.
