Description

Technical Field

[0001] The present application relates to the field of mechanical processing, and in particular to a root canal file fixture and grinding equipment. Background Art

[0002] The root canal file has a main body and a tip that are coaxially connected. In order to grind the tip of the root canal file, a staff member usually holds the main body of the root canal file to expose the conical tip, and grinds the tip with a grinding assembly to grind the outer surface of the tip smooth. However, this easily causes the central axis of the grinded tip to shift, resulting in the central axis of the grinded tip not coinciding with the central axis of the main body, the coaxiality of the tip and the main body is low, and the central axis of the grinded root canal file is offset. Utility Model Content

[0003] In view of this, it is necessary to provide a root canal file fixture and grinding equipment, which can obtain a root canal file with a smooth outer surface and a high coaxiality between the main body and the tip.

[0004] In one embodiment of the present application, a root canal file clamp is provided, comprising a base, a bearing member and a moving member, wherein the bearing member is connected to the base and rotates around a rotation axis, the bearing member has a bearing surface, the bearing surface is used to bear a portion of the root canal file and make the central axis of the root canal file coincide with the rotation axis; the moving member is connected to the bearing member, the moving member has a positioning surface arranged opposite to the bearing surface, the positioning surface moves toward the bearing surface, so that the positioning surface and the bearing surface clamp a portion of the root canal file.

[0005] In the above-mentioned clamp, the base is rotatably connected to the supporting member, so that the supporting member can drive the moving member to rotate relative to the base around the rotation axis, the moving member and the supporting member clamp part of the root canal file through the positioning surface and the supporting surface, and make the central axis of the root canal file coincide with the rotation axis, and the supporting member and the root canal file are kept coaxially arranged, at this time, the moving member and the supporting member clamp the main body of the root canal file, and the tip of the root canal file is exposed from the moving member and the supporting member. When the root canal file rotates around the rotation axis with the supporting member, the outer surface of the tip can be polished to obtain a tip with a smooth outer surface, and the central axis of the polished tip can be kept coincident with the rotation axis. Since the central axis of the root canal file before polishing coincides with the rotation axis, the central axis of the polished tip coincides with the central axis of the root canal file before polishing, and the central axis of the root canal file after polishing is not offset compared with the central axis of the root canal file before polishing, and the polished tip is coaxial with the main body.

[0006] In some embodiments, the cross-section of the bearing surface is arc-shaped, and the center of the cross-section of the bearing surface falls on the rotation axis. When the bearing surface carries the root canal file, the center of the cross-section of the bearing surface falls on the central axis of the root canal file, so that the central axis of the root canal file coincides with the rotation axis.

[0007] In some embodiments, the cross section of the positioning surface is in the shape of an arc.

[0008] In some embodiments, the radius of the cross section of the positioning surface is the same as the radius of the cross section of the bearing surface, and the cross section of the portion of the root canal file sandwiched by the bearing surface and the positioning surface is the same as the radius of the cross section of the positioning surface.

[0009] In some embodiments, the base includes a first side frame and a second side frame spaced apart along the axial direction of the support member, the first side frame is connected to the second side frame, and the rotation axis is parallel to the axial direction of the support member; the support member includes a coaxially connected rotating part and an extension part, the rotating part is rotatably connected to the first side frame and the second side frame, the extension part is located on the side of the first side frame away from the second side frame, and the bearing surface is arranged on the extension part.

[0010] In some embodiments, the driving assembly includes a motor coaxially connected to an end of the rotating portion away from the extending portion.

[0011] In some embodiments, the clamp further includes two bearings, the first side frame and the second side frame are both provided with through holes, each through hole is connected to a bearing, and the rotating part is passed through the bearings, so that the base and the bearing are rotatably connected through the bearings.

[0012] In some embodiments, the clamp further includes a stopper connected to the rotating portion and located on a side of the second side frame away from the first side frame to limit the rotating portion from moving relative to the base in an axial direction parallel to the bearing member.

[0013] In some embodiments, the moving part includes a bracket, a cylinder and a pressure block. The bracket is connected to the rotating part and is located on the side of the first side frame away from the second side frame. The cylinder is arranged on the bracket, the pressure block is connected to the cylinder, and the positioning surface is arranged on the side of the pressure block away from the cylinder. The cylinder drives the pressure block to move so that the positioning surface moves close to or away from the bearing surface.

[0014] In some embodiments, an end of the extension portion away from the first side frame and an end of the pressing block away from the first side frame are located in the same plane.

[0015] The present application also provides a grinding device, including a driving component, a grinding component and the above-mentioned clamp, the grinding component having a grinding surface with a preset angle, the driving component being connected to a carrier to drive the carrier to rotate around a rotation axis, so that the portion of the root canal file exposed from the clamp rotates through the grinding surface to grind the outer surface of the portion of the root canal file exposed from the clamp.

[0016] In the above-mentioned grinding device, a part of the root canal file is clamped by a clamp and a part of the root canal file is exposed, that is, the clamp clamps the main body of the root canal file and exposes the tip of the root canal file. The grinding component presets the grinding surface to a certain angle according to the shape of the tip, so that the contact surface fits the outer surface of the tip. The driving component drives the carrier to rotate around the rotation axis, so that the clamp drives the root canal file to rotate around the rotation axis, and the tip rotates through the grinding surface, so that the grinding surface grinds the outer surface of the tip through friction. When the root canal file rotates around the rotation axis with the carrier, the outer surface of the tip can be polished to obtain a tip with a smooth outer surface, and the central axis of the polished tip can remain coincident with the rotation axis. Since the central axis of the root canal file before grinding coincides with the rotation axis, the central axis of the polished tip coincides with the central axis of the root canal file before grinding, and the central axis of the root canal file after grinding does not deviate from the central axis of the root canal file before grinding, and the polished tip is coaxial with the main body.

[0030] The technical solution of the present application will be described below in conjunction with the drawings in the implementation modes of the present application. Obviously, the described implementation modes are only part of the implementation modes of the present application, rather than all the implementation modes.

[0031] It should be noted that when a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a component centered. When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may also be a component centered. When a component is considered to be "set on" another component, it may be directly set on the other component or there may also be a component centered. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0032] In addition, the term "perpendicular" is used to describe an ideal state between two components. In actual production or use, the two components may be approximately perpendicular to each other. The two components described as "perpendicular" may not be absolutely straight lines or planes, but may be roughly straight lines or planes. From a macroscopic point of view, the components can be considered "straight lines" or "planes" if the overall extension direction is a straight line or a plane.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0034] During the production and processing of the root canal file, in order to grind the end of the root canal file, a worker usually holds the main body of the root canal file, exposing the tip of the tapered root canal file, and grinds the tip with a grinding assembly to grind the outer surface of the tip smooth. However, such grinding of the tip easily causes uneven force on the outer surface of the tip, thereby causing the axis of the tip to deviate from the central axis of the root canal file, and the coaxiality of the tip and the main body is low.

[0035] In view of this, it is necessary to provide a root canal file fixture and a grinding device that can prevent the axis of the tip from deviating from the central axis of the root canal file.

[0036] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0037] See also Figure 1 and Figure 4In one embodiment of the present application, a root canal file 200 fixture 100 and a grinding device are provided, wherein the grinding device includes the fixture 100. The grinding device is used to grind the portion of the root canal file 200 held by the fixture 100 that is exposed from the fixture 100.

[0038] As an illustrative example, see Figure 5 The root canal file 200 includes a main body 210 and a tip 220, which are coaxially arranged along the central axis 200a of the root canal file. The clamp 100 clamps the main body 210 to expose the tip 220, and the grinding device grinds the outer surface of the tip 220 to make the outer surface of the tip 220 smooth and of qualified quality.

[0039] In some embodiments, the grinding device further includes a driving component and a grinding component. The grinding component has a grinding surface with a preset angle. The grinding component can preset the grinding surface to a certain angle according to the shape of the tip 220, so that the contact surface fits the outer surface of the tip 220. The driving component is used to drive the root canal file 200 clamped by the clamp 100 to rotate around the rotation axis 20a, so that the part of the root canal file 200 exposed from the clamp 100 rotates through the grinding surface, so as to grind the outer surface of the part of the root canal file 200 exposed from the clamp 100. That is, the tip 220 rotates through the grinding surface, and the grinding surface grinds the outer surface of the tip 220 through friction, thereby achieving the effect of grinding the outer surface of the tip 220.

[0040] As an illustrative example, see Figure 2 The side of the tip 220 is an isosceles triangle. The waist of the isosceles triangle falls on the polishing surface. When the tip 220 rotates around the rotation axis 20a, the outer surface of the tip 220 rotates through the polishing surface, and the outer surface of the tip 220 can be polished smooth.

[0041] In some embodiments, see Figures 1 to 4 The fixture 100 includes a base 10, a bearing member 20 and a moving member 30. The base 10 is fixedly arranged. The base 10 is used to mount the bearing member 20 so that the bearing member 20 is connected to the base 10 to rotate around the rotation axis 20a. The bearing member 20 is used to carry the root canal file 200. The driving assembly is connected to the bearing member 20 to drive the bearing member 20 to rotate around the rotation axis 20a relative to the base 10. The moving member 30 is connected to the bearing member 20 to move with the bearing member 20. The moving member 30 is used to fix the root canal file 200 to the bearing member 20. Among them, the bearing member 20 carries the main body 210, and the moving member 30 fixes the main body 210 to the bearing member 20, so that the tip 220 is exposed to the bearing member 20 and the moving member 30.

[0042] See also Figure 4The bearing member 20 has a bearing surface 221. The bearing surface 221 is used to bear part of the root canal file 200, and make the central axis 200a of the root canal file coincide with the rotation axis 20a. The moving member 30 has a positioning surface 331 arranged opposite to the bearing surface 221. The positioning surface 331 moves toward the bearing surface 221, so that the positioning surface 331 and the bearing surface 221 clamp part of the root canal file 200. The bearing member 20 and the moving member 30 clamp and fix the main body 210 of the root canal file 200 through the bearing surface 221 and the positioning surface 331, so that the tip 220 of the root canal file 200 is exposed.

[0043] When in use, the driving assembly drives the carrier 20 to rotate around the rotation axis 20a, so that the tip 220 rotates around the rotation axis 20a. The tip 220 rotates through the polishing surface to polish the outer surface of the tip 220, and the central axis of the polished tip 220 can remain coincident with the rotation axis 20a.

[0044] Since the outer circumference of the main body 210 clamped by the clamp 100 has not been processed and does not need to be polished using a polishing device, the central axis of the main body 210 always remains in a state of coinciding with the rotation axis 20 a.

[0045] Since the central axis 200a of the root canal file before grinding coincides with the rotation axis 20a, the central axis of the tip 220 after grinding can keep coinciding with the rotation axis 20a, so the central axis of the tip 220 after grinding coincides with the central axis 200a of the root canal file before grinding. The central axis 200a of the root canal file after grinding does not deviate from the central axis 200a of the root canal file before grinding. The tip 220 after grinding is coaxial with the main body 210.

[0046] In some embodiments, the clamp 100 clamps the entire body 210, leaving only the tip 220 exposed. This allows a larger portion of the root canal file 200 to be clamped, and the clamping is more stable.

[0047] In some embodiments, see Figure 1 The fixture 100 clamps two-thirds of the main body 210, and exposes one-third of the main body 210 and the tip 220. This allows the root canal file 200 to be stably clamped by the fixture 100, and exposes more for processing the tip 220.

[0048] In some embodiments, see Figure 3 and 4 The cross section of the bearing surface 221 is in an arc shape. The center of the cross section of the bearing surface 221 falls on the rotation axis 20a. When the bearing surface 221 carries the root canal file 200, the center of the cross section of the bearing surface 221 falls on the central axis 200a of the root canal file, so that the central axis 200a of the root canal file coincides with the rotation axis 20a.

[0049] It can be understood that the bearing surface 221 is a concave arc surface. Such a bearing surface 221 can position the root canal file 200 to prevent the root canal file 200 from rolling on the bearing surface 221, and can also adapt to the outer periphery of the root canal file 200 to fit the root canal file 200, and can cooperate with the positioning surface 331 to stably clamp the root canal file 200.

[0050] In some embodiments, the cross section of the positioning surface 331 is in an arc shape. It is understandable that the bearing surface 221 is a concave arc surface, and such a positioning surface 331 can position the root canal file 200 to prevent the root canal file 200 from rolling relative to the positioning surface 331, and can also adapt to the outer periphery of the root canal file 200 to fit the root canal file 200.

[0051] See also Figure 3 The positioning surface 331 with an arc-shaped cross section moves toward the bearing surface 221 with an arc-shaped cross section, so that the bearing surface 221 and the positioning surface 331 can form a channel 60 that can accommodate the root canal file 200. The root canal file 200 passes through the channel 60 and is clamped in the channel 60 by the bearing surface 221 and the positioning surface 331.

[0052] In some embodiments, see Figure 4 The end of the carrier 20 is provided with a chamfer 222 connected to the carrier surface 221. The chamfer 222 is used to guide the root canal file 200 into the channel 60.

[0053] In some embodiments, the radius of the cross section of the positioning surface 331 is the same as the radius of the cross section of the bearing surface 221. The cross section of the portion of the root canal file 200 clamped by the bearing surface 221 and the positioning surface 331 is the same as the radius of the cross section of the positioning surface 331. The bearing surface 221 and the positioning surface 331 both fit the outer circumference of the root canal file 200, can stably clamp the root canal file 200, can drive the root canal file 200 to rotate around the rotation axis 20a, and prevent the root canal file 200 from moving relative to the bearing member 20 and the moving member 30.

[0054] It can be understood that when the radius of the cross section of the bearing surface 221 is the same as the radius of the main body 210 of the root canal file 200, the bearing surface 221 can position the root canal file 200 by bearing the root canal file 200, and can prevent the root canal file 200 from rolling on the bearing surface 221. When the radius of the cross section of the positioning surface 331 is the same as the radius of the main body 210 of the root canal file 200, the positioning surface 331 can position the root canal file 200, and can prevent the root canal file 200 from rolling relative to the positioning surface 331. When the radius of the cross section of the bearing surface 221, the radius of the cross section of the positioning surface 331, and the radius of the main body 210 of the root canal file 200 are the same, the root canal file 200 can be better clamped and positioned.

[0055] In some embodiments, the cross-sections of the positioning surface 331 and the bearing surface 221 may also be larger than the radius of the root canal file 200 so as to clamp the root canal files 200 of different sizes.

[0056] In some embodiments, see Figure 1 and Figure 2 The base 10 includes a first side frame 11 and a second side frame 12 which are arranged at intervals along the axial direction X of the bearing member 20. The first side frame 11 is connected to the second side frame 12. The first side frame 11 and the second side frame 12 are connected by a bottom plate 13, and the bottom plate 13 extends along the axial direction X. The rotation axis 20a is parallel to the axial direction X of the bearing member 20. The central axis of the bearing member 20 coincides with the rotation axis 20a. The bearing member 20 includes a rotating part 21 and an extending part 22 which are coaxially connected. The rotating part 21 is rotatably connected to the first side frame 11 and the second side frame 12. The base 10 can support both ends of the rotating part 21, so that the rotating part 21 can be rotatably connected to the base 10 more stably. The extending part 22 is provided on the side of the first side frame 11 away from the second side frame 12, and the bearing surface 221 is provided on the extending part 22 to prevent the base 10 from hindering the moving part 30 from abutting the root canal file 200 against the bearing surface 221.

[0057] In some embodiments, see Figure 1 The fixture 100 further includes two bearings 40. Through holes are provided on the first side frame 11 and the second side frame 12. Each through hole is connected to a bearing 40. The rotating portion 21 is passed through the bearing 40, so that the base 10 and the bearing 20 are rotatably connected through the bearing 40. The bearing 20 is connected to the base 10 through the bearing 40, which can limit the bearing 20 from being separated from the base 10, so that the bearing 20 can only rotate around the rotation axis 20a, and the bearing 40 can make the rotation of the bearing 20 more stable.

[0058] In some embodiments, see Figure 1 and Figure 2 The movable member 30 includes a bracket 31, a cylinder 32 and a pressing block 33. The bracket 31 is connected to the rotating portion 21 and is located on the side of the first side frame 11 away from the second side frame 12, so that the pressing block 33 can be arranged opposite to the extension portion 22, and the bracket 31 can also limit the rotation portion 21 from moving along the axial direction X relative to the base 10. The cylinder 32 is arranged on the bracket 31, the pressing block 33 is connected to the cylinder 32, and the positioning surface 331 is arranged on the side of the pressing block 33 away from the cylinder 32, so that the positioning surface 331 can be arranged opposite to the bearing surface 221 arranged on the extension portion 22. The cylinder 32 drives the pressing block 33 to move, so that the positioning surface 331 moves close to or away from the bearing surface 221, so that the positioning surface 331 and the bearing surface 221 clamp or release the root canal file 200.

[0059] In some embodiments, the fixture 100 further includes a stopper 50. The stopper 50 is connected to the rotating portion 21 and is located on a side of the second side frame 12 away from the first side frame 11 to limit the rotating portion 21 from moving relative to the base 10 in the axial direction X parallel to the bearing member 20. Specifically, the stopper 50 limits the rotating portion 21 from moving relative to the base 10 in the opposite direction of the axial direction X.

[0060] As an illustrative example, the stopper 50 is a nut, and the nut is threadedly connected to the rotating part 21 .

[0061] In some embodiments, the end of the extension 22 away from the first side frame 11 and the end of the pressing block 33 away from the first side frame 11 are located in the same plane. The root canal file 200 is subjected to force balance, and the central axis of the main body 210 always coincides with the rotation axis X to prevent the central axis of the main body 210 from deflecting.

[0062] It can be understood that the positioning surface 331 abuts against the upper surface of the root canal file 200, so that the lower surface of the root canal file 200 abuts against the bearing surface 221. In the axial X direction, the abutting length of the extension surface is the same as the abutting length of the bearing surface 221, which can prevent the root canal file 200 from being damaged due to uneven force.

[0063] In addition, those skilled in the art should recognize that the above embodiments are only used to illustrate the present application and are not intended to be limiting of the present application. As long as they are within the spirit and scope of the present application, appropriate changes and modifications to the above embodiments are within the scope of the present application.
