Description

Technical Field

[0001] The present invention relates to the technical field of drill bit processing, and specifically to a finishing device and a processing technology for drill bit production. Background Art

[0002] When performing operations such as root canal reaming of teeth or bone drilling in the human body, drill bits are required for drilling. When drill bits are produced, burrs are present on their surfaces. Due to the high precision requirements of root canal reaming of teeth and bone drilling in the human body, the drill bits used must undergo polishing and deburring treatment.

[0003] Since the volume of such drill bits is relatively small, the workmanship is precise, and the spiral groove gaps on the drill bits are small, it is inconvenient to polish them. Traditionally, the polishing of such drill bits is usually completed by introducing abrasive flow. The drill bit is fixed in a container, and then abrasive flow is introduced from one end of the container, so that the abrasive flow circulates in the container and finally flows out from the other end of the container. Since the drill bit is relatively small, if the drill bit is perpendicular to the direction of the abrasive flow, the drill bit will be subjected to a large pressure and is easily bent by the abrasive flow. If the drilling position of the drill bit is directly facing the direction of the abrasive flow, the tip position of the drill bit is relatively easy to be ground flat by the abrasive flow. Therefore, fixing the drill bit at a position where the drilling direction is the same as the direction of the abrasive flow can achieve the best polishing effect on the drill bit and prevent the drill bit from being damaged. However, due to the small volume of the drill bit, it is inconvenient to adjust multiple drill bits into one direction and fix them in the container. Summary of the Invention

A reset mechanism is provided on the clamping plate. The reset mechanism is used to drive the clamping plate to reset after the clamping plate is separated from the pressing plate.

[0014] A finishing process for drill bit production, and the specific steps of this process are as follows:

[0015] Step 1: Start the feeding box on the left or right side, and transport the drill bits to be polished into the adjustment frame of the conveyor belt at one time.

[0016] Step 2: After the drill bit enters the adjustment frame, start the driving mechanism. The driving mechanism drives the adjustment mechanism to operate, and the drill bit is adjusted to a state where the drilling part faces upward through the adjustment mechanism.

[0017] Step 3: The driving mechanism drives the polishing mechanism to operate. The polishing mechanism fixes the adjusted drill bits one by one and drives the drill bits to move to the polishing position in sequence.

[0018] Step 4: Start the abrasive flow box, and complete the polishing of all drill bits through the abrasive flow in sequence.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. In the present invention, by starting the feeding box on the left or right side, the drill bits are transported to the adjustment frame in sequence. At this time, start the driving mechanism. The driving mechanism can drive the adjustment mechanism to operate, and through the adjustment mechanism, all the drill bits on the adjustment frame can be adjusted to a state where the drilling position faces upward, and the drill bits are discharged while maintaining the state where the drilling position faces upward. At the same time, the driving mechanism will drive the rod polishing mechanism to operate. The polishing mechanism fixes the drill bits adjusted by the adjustment mechanism and drives the drill bits to move to the polishing position. At this time, start the abrasive flow box, and complete the polishing of the drill bits through the abrasive flow discharged from the abrasive flow box. After the polishing of the drill bits is completed, the polishing mechanism will release the drill bits. This device is simple to operate and convenient to use. It can automatically adjust the disordered drill bits to the state where the drilling position faces upward, then fix the drill bits, and polish the drill bits by making the abrasive flow flow upward from the bottom position of the drill bits, which can effectively improve the polishing effect of the drill bits and will not damage the drill bits at the same time.

[0021] 2. In the present invention, the first driving frame pushes the drill bit to move on the adjustment plate and the support rod. When the drill bit moves to the downward concave position on the adjustment plate, since the weight of the tail of the drill bit is heavier than that of the head of the drill bit, the tail of the drill bit will rotate downward along the support rod, and the head of the drill bit will tilt upward. When the drill bit is pushed to the middle position of the adjustment plate, the drill bit will fall into the discharge pipe in a state where the tail is downward and the head is upward, and then directly fall into the polishing cylinder from the discharge pipe. Then, during the movement of the polishing cylinder, the two pressing plates squeeze the clamping plate, so that the clamping plate can clamp the drill bit; thus, the drill bit can be fixed in a state where the drilling position faces upward.

[0036] Please refer to Figures 1-12, the present invention provides a technical solution: a finishing device for drill bit production and its processing technology, including an operating table 1, on which two abrasive flow boxes 2 and two feeding boxes 3 are fixedly connected; an adjusting frame 4 is arranged between the two feeding boxes 3, and the adjusting frame 4 is fixedly connected with the two abrasive flow boxes 2; an adjusting mechanism is arranged inside the adjusting frame 4, and the adjusting mechanism is used to adjust all the drill bits transported into the adjusting frame 4 to a position where the drilling position is upward; a polishing mechanism is arranged at the bottom of the adjusting frame 4, and the polishing mechanism is used to fix the drill bits adjusted by the adjusting mechanism in a position where the drilling direction is upward and then polish them by flowing the abrasive flow upward from the bottom position of the drill bits; a driving mechanism is arranged on the operating table 1, and the driving mechanism is used to drive the adjusting mechanism and the clamping mechanism to operate;

[0037] As Figure 1 shown, during operation, when it is necessary to polish the drill bits, by starting the left or right feeding box 3, the drill bits are sequentially transported onto the adjusting frame 4. At this time, the driving mechanism is started, and the driving mechanism can drive the adjusting mechanism to operate. Through the adjusting mechanism, all the drill bits on the adjusting frame 4 can be adjusted to a state where the drilling position is upward, and the drill bits are discharged while maintaining the state where the drilling position is upward; at the same time, the driving mechanism will drive the rod polishing mechanism to operate. The polishing mechanism fixes the drill bits adjusted by the adjusting mechanism and drives the drill bits to move to the polishing position. At this time, the abrasive flow box 2 is started, and the abrasive flow discharged from the abrasive flow box 2 completes the polishing of the drill bits. After the drill bits are polished, the polishing mechanism will release the drill bits; the device is simple to operate and convenient to use. It can automatically adjust the disordered drill bits to a state where the drilling position is upward, then fix the drill bits and polish the drill bits by flowing the abrasive flow upward from the bottom position of the drill bits, which can effectively improve the polishing effect of the drill bits and will not damage the drill bits at the same time.

[0038] As Figures 6-7 shown, as a further solution of the present invention, the adjusting mechanism includes an annular plate 5, which is located inside the adjusting frame 4 and fixedly connected with the adjusting frame 4. The middle parts of the front and rear sides of the annular plate 5 are concave downward; a support rod 6 is fixedly connected to the middle position of the annular plate 5, and the support rod 6 is at the same height as the annular plate 5; receiving rods 7 are symmetrically and fixedly connected to the left and right sides of the annular plate 5, and the receiving rods 7 are in contact with the discharging positions of the feeding boxes 3; drill bits are arranged on the support rod 6 and the annular plate 5; a first driving frame 8 is arranged on the upper side of the support rod 6, and the first driving frame 8 has a clearance fit with the support rod 6 and the drill bits; discharge pipes 9 are symmetrically and fixedly connected to the front and rear sides of the middle part of the adjusting frame 4;

[0039] During operation, when the feeding box 3 discharges the drill bits onto the receiving rod 7, in this process, the drill bits will exactly directly insert into the empty slots of the first driving frame 8, and then drive the first driving frame 8 to move left or right. When the first driving frame 8 moves, it will drive the drill bits to move to the adjusting plate and the support rod 6. When the drill bits move to the sunken position on the adjusting plate, since the weight of the tail of the drill bit is greater than the weight of the drilling part of the drill bit, the tail of the drill bit will gradually rotate downward along the support rod 6, and the drilling part of the drill bit will gradually tilt upward; when the first driving frame 8 drives the drill bits to move to the middle position of the adjusting plate, at this time, the tail of the drill bit rotates to the bottommost position and is exactly located at the position of the discharge pipe 9. At this time, the tail of the drill bit loses the block of the adjusting frame 4 and thus directly slides into the discharge pipe 9, and in the discharge pipe 9, it drops downward while maintaining the state of the tail downward and the drilling position upward.

[0040] As Figures 8-9 shown, as a further solution of the present invention, the polishing mechanism includes a second driving frame 10. On the front and rear sides of the second driving frame 10, a plurality of rotating frames 11 are symmetrically rotatably connected. A polishing cylinder 12 is fixedly connected to the rotating frame 11. The inner diameter of the polishing cylinder 12 is larger than the diameter of the drill bit, and the polishing cylinders 12 at the front and rear positions are respectively located at the bottom positions of the discharge pipes 9 at the front and rear sides; a clamping mechanism is provided on the rotating frame 11. The clamping mechanism is used to clamp the drill bit when the drill bit enters the polishing cylinder 12 and release the drill bit after the drill bit in the polishing cylinder 12 is polished; a detection mechanism is provided on the second driving frame 10. The detection mechanism is used to drive the abrasive flow tank 2 to inject abrasive flow into the polishing cylinder 12 to polish the drill bit when it detects that the polishing cylinder 12 located directly below the discharge pipe 9 contains a drill bit;

[0041] During operation, when the drill bits fall from the discharge pipe 9, they can directly fall into the polishing cylinder 12 located at the bottom position of the discharge pipe 9. At this time, drive the rotating frame 11 to drive the polishing cylinder 12 to move left or right. During the movement, the clamping mechanism will automatically clamp to fix the drill bit in the polishing cylinder 12; before the rotating frame 11 drives the polishing cylinder 12 to move, first detect whether the polishing cylinder 12 located at the bottom position of the discharge pipe 9 contains a drill bit through the detection mechanism. If there is no drill bit, when the polishing cylinder 12 moves to the polishing position, the abrasive flow tank 2 will not discharge abrasive flow; if the polishing cylinder 12 contains a drill bit, when the polishing cylinder 12 moves to the polishing position, it will drive the abrasive flow tank 2 to discharge abrasive flow to complete the polishing of the drill bit. After the drill bit is polished, as the rotating frame 11 drives the polishing cylinder 12 to continue moving, the clamping mechanism will release the drill bit and automatically discharge the drill bit.

[0042] As Figures 9-12As shown in the figure, as a further solution of the present invention, the clamping mechanism includes four pressing plates 13. Two pressing plates 13 are symmetrically distributed on the front and rear sides of the front-side rotating frame 11, and the other two pressing plates 13 are symmetrically distributed on the front and rear sides of the rear-side rotating frame 11; a connecting rod 14 is fixedly connected to the adjusting frame 4, and the connecting rod 14 is fixedly connected to the two pressing plates 13 at the middle position; the pressing plates 13 at the front and rear sides are respectively fixedly connected to the abrasive flow boxes 2 at the front and rear sides; the distance between the middle position and the left and right sides of the two pressing plates 13 at the front and rear sides is greater than the distance between other parts; symmetrically sliding connections are provided at the front and rear sides of the rotating frame 11 with clamping plates 15, the clamping plates 15 are attached to the bottom end of the polishing cylinder 12, and the clamping plates 15 at the front and rear sides are respectively attached to the pressing plates 13 at the front and rear sides of the rotating frame 11; a reset mechanism is provided on the clamping plate 15, and the reset mechanism is used to drive the clamping plate 15 to reset after the clamping plate 15 is separated from the pressing plate 13; a guiding mechanism is provided on the abrasive flow box 2, and the guiding mechanism is used to guide the polishing cylinder 12 to complete polishing. After the drill bit in the polishing cylinder 12 is polished, it guides the rotating frame 11 to drive the polishing cylinder 12 to rotate to the bottom position to discharge the drill bit and the abrasive flow;

[0043] The reset mechanism includes two sliders 16. The two sliders 16 are symmetrically distributed on the left and right sides of the rotating frame 11, and the sliders 16 are slidably connected to the rotating frame 11; a spring 17 is fixedly connected to the slider 16, and the other end of the spring 17 is fixedly connected to the rotating frame 11; connecting rods 18 are rotatably connected to the front and rear sides of the slider 16, and the front and rear connecting rods 18 are respectively rotatably connected to the front and rear clamping plates 15;

[0044] The guiding mechanism includes a first guiding rod 19 and two second guiding rods 20. The first guiding rod 19 is fixedly connected to the abrasive flow box 2, and the two second guiding rods 20 are symmetrically distributed on the left and right sides of the first guiding rod 19, and the second guiding rod 20 is fixedly connected to the first guiding rod 19; the second guiding rod 20 is in a spiral shape with a half turn of the thread; a torsion spring 21 is fixedly connected to the rotating frame 11 at the position where it is connected to the second driving frame 10, and the other end of the torsion spring 21 is fixedly connected to the rotating frame 11; the front-side polishing cylinder 12 is attached to the front-side first guiding rod 19 and the second guiding rod 20, and the rear-side polishing cylinder 12 is attached to the rear-side first guiding rod 19 and the second guiding rod 20; feeding pipes 22 are symmetrically and fixedly connected to the left and right sides of the abrasive flow box 2, a receiving pipe 23 is fixedly connected to the bottom position of the polishing cylinder 12, the feeding pipe 22 and the receiving pipe 23 are at the same height and the feeding pipe 22 is in snap-fit connection with the receiving pipe 23; a sealing plate 24 is fixedly connected to the first guiding rod 19 above the feeding pipe 22, and a discharge hole 25 is opened on the sealing plate 24; the sealing plate 24 is attached to the upper end of the polishing cylinder 12;

[0045] During operation, when the drill bit drops downward from the discharge pipe 9, the polishing cylinder 12 located at the bottom of the discharge pipe 9 is in contact with the first guiding rod 19 under the action of the torsion spring 21. Supported by the first guiding rod 19, the polishing cylinder 12 remains vertical, so that the dropped drill bit can directly fall into the polishing cylinder 12. Then, the second driving frame 10 is driven to drive the rotating frame 11 and the polishing cylinder 12 to move left or right. When the rotating frame 11 moves, the clamping plates 15 on the front and rear sides of the rotating frame 11 will be squeezed by the pressing plates 13 on the front and rear sides of the rotating frame 11, so that the two clamping plates 15 will move towards each other. When the two clamping plates 15 move to the position where they are in contact with each other, the two clamping plates 15 can clamp the tail of the drill bit in the polishing cylinder 12 and seal the bottom end of the polishing cylinder 12 at the same time. The first driving frame 8 continues to drive the polishing cylinder 12 to move. When the receiving pipe 23 on the polishing cylinder 12 moves to the position where it is clamped to the feeding pipe 22 on the abrasive flow box 2, the sealing plate 24 above the feeding pipe 22 just seals the upper end of the polishing cylinder 12. Then, the driving of the second driving frame 10 is stopped and the abrasive flow box 2 is started. The abrasive flow box 2 injects the abrasive flow into the polishing cylinder 12 through the feeding pipe 22 and the receiving pipe 23. After the abrasive flow enters the polishing cylinder 12, it flows from bottom to top, so that the polishing of the drill bit can be completed. When the drill bit is polished, the second driving frame 10 is continuously driven to move. During the movement of the rotating frame 11 and the polishing cylinder 12, since the distance between the two pressing plates 13 at this part is getting larger and larger, the two clamping plates 15 fixing the drill bit gradually separate under the action of the two connecting rods 18 of the spring 17, so that the drill bit is no longer fixed. When the polishing cylinder 12 moves to the position where it is in contact with the second guiding rod 20, the rotating frame 11 will gradually rotate downward along with the second guiding rod 20 under the action of the torsion spring 21, so that the abrasive flow and the drill bit in the polishing cylinder 12 can be poured out.

[0046] As Figure 9As shown in the figure, as a further solution of the present invention, the detection mechanism includes an infrared emitter 26 and two infrared receivers 27; the infrared emitter 26 is fixedly connected to the connecting rod 14 and the infrared emitter 26 has emission ports in the front and rear directions; the two infrared receivers 27 are distributed on the front and rear sides of the infrared emitter 26, and the infrared receivers 27 on the front and rear sides are respectively fixedly connected to the abrasive flow boxes 2 on the front and rear sides; the infrared emitter 26 is located at the bottom of the clamping plate 15 and above the bottom side of the rotating frame 11; the infrared emitter 26 and the infrared receivers 27 are at the same height; during operation, since only one drill bit can fall from the drill bits in the adjustment frame 4 at a time, the infrared emitter 26 emits infrared rays in the front and rear directions, and the infrared rays will irradiate the infrared receivers 27 through the rotating frame 11. When a drill bit falls from one of the discharge pipes 9, the drill bit will block the infrared rays on the front side or the rear side, and the infrared receivers 27 on the front side or the rear side will not be able to receive the infrared rays, so that it can be detected that the polishing cylinder 12 at the front side or the rear side contains a drill bit, and then the corresponding abrasive flow box 2 can be started to discharge the abrasive flow to polish the drill bit.

[0047] As Figures 3-4 shown in the figure, as a further solution of the present invention, the driving mechanism includes a support frame 28, and the support frame 28 is fixedly connected to the operating table 1; the first driving frame 8 and the second driving frame 10 are both slidably connected to the support frame 28; a motor 29 is fixedly connected to the left side position on the operating table 1, the right end of the output shaft of the motor 29 is fixedly connected to a first pulley 30, and a belt 31 is provided on the first pulley 30; threaded rods 32 are symmetrically provided at the upper and lower positions of the support frame 28, and the threaded rods 32 at the upper and lower sides are respectively in threaded cooperation with the first driving frame 8 and the second driving frame 10; the left end of the threaded rod 32 is fixedly connected to a second pulley 33, and the belt 31 is meshed with the first pulley 30 and the two second pulleys 33 at the same time; during operation, when it is necessary to drive the first driving frame 8 and the second driving frame 10 to move, the motor 29 is started to drive the first pulley 30 to rotate. When the first pulley 30 rotates, the belt 31 can drive the second pulleys 33 at the upper and lower sides to rotate, and the second pulley 33 drives the threaded rod 32 to rotate.
