Description

Technical Field

[0001] The present disclosure relates to the technical field of nail art tools, and particularly to a grinding tool and a forming method thereof. Background Art

[0002] In the nail art industry, the use of photocurable glue is extremely common. After the photocurable glue is cured, it needs to be polished to be effectively removed. Currently, nail art grinding tools rely on manual operation, which may cause damage to the nails and have poor grinding safety. Summary of the Invention

[0003] Embodiments of the present disclosure propose a grinding tool and a forming method thereof to improve the safety during the grinding process. Even if the pressure of the grinding head on the nail surface is large or the grinding head is tilted to a certain extent, the true nail part will not be damaged.

The size of the mounting opening is determined to be suitable for accommodating the mounting assembly and the base, and the first mounting portion is mounted on the mounting protrusion.

[0009] In some embodiments, the mounting assembly includes a first part and a second part that are fixedly connected. The first part extends along the direction of the rotation axis of the grinding head, and the second part extends along a direction perpendicular to the extension direction of the first part. The first part is connected to the grinding head, and the second part is rotatably connected to the base.

[0010] In some embodiments, the base includes a first opening and a second opening. In a direction perpendicular to the direction of the rotation axis of the grinding head, the size of the first opening is smaller than that of the second opening. The size of the first opening is determined to be suitable for accommodating the first part, and the size of the second opening is determined to be suitable for accommodating the second part.

[0011] In some embodiments, at one end of the grinding head close to the base, a first mounting structure and a second mounting structure are provided. The first part passes through the first opening and the second opening and is fixedly connected to the first mounting structure, and the second mounting structure is adapted to the base.

[0012] In some embodiments, the grinding tool further includes a washer, and the washer is disposed on the surface of the base facing the grinding head.

[0013] In some embodiments, the driving member includes a transmission shaft and a power source. The transmission shaft is integrally formed with the grinding head. One end of the transmission shaft away from the grinding head is connected to the power source, and the power source drives the transmission shaft to rotate.

[0014] In a second aspect, an embodiment of the present disclosure provides a method for forming a grinding tool, including: mounting the grinding head on the driving member; and using a mounting assembly to mount the base on one end of the grinding head away from the driving member so that the base is rotatably connected to the grinding head; wherein: the grinding head rotates under the drive of the driving member, and when the grinding head grinds the object to be ground, the base does not rotate with the grinding head.

[0015] In some embodiments, the grinding head includes a mounting opening and a mounting protrusion. The mounting opening is recessed in a direction away from the base, and the mounting protrusion is located in the mounting opening; and the mounting assembly includes a first mounting portion and a second mounting portion, and the first mounting portion and the second mounting portion are rotatably connected. Using the mounting assembly to mount the base on one end of the grinding head away from the driving member includes: mounting the first mounting portion on the mounting protrusion, and placing the second mounting portion in the mounting opening and fixedly connecting the second mounting portion to the base.

[0016] In some embodiments, the grinding head includes a first mounting structure and a second mounting structure; the base includes a first opening and a second opening; and the mounting assembly includes a first part and a second part fixedly connected. The first part extends along the direction of the rotation axis of the grinding head, and the second part extends along a direction perpendicular to the extension direction of the first part. Using the mounting assembly to mount the base on one end of the grinding head away from the driving member includes: passing the first part through the first opening and the second opening and fixedly connecting it to the first mounting structure, and placing the base in the second mounting structure so that the base is rotatably connected to the second part.

[0017] In some embodiments, the method for forming the grinding head further includes: forming a washer on the surface of the base facing the grinding head.

[0018] In some embodiments, the circumferential surface of the grinding head is the grinding surface. After installing the base to one end of the grinding head away from the driving member using the installation component, it further includes: hardening or rust-proofing the grinding surface.

[0019] For the grinding tool provided by the present disclosure, the installation component is used to achieve the rotatable connection between the base and the grinding head. The base does not rotate with the grinding head during the process of the grinding head grinding the object to be ground. For example, when grinding the photocuring glue on the nail surface, the base can be in contact with the nail surface. The setting of the base can improve the safety during the grinding process. Even if the pressure of the grinding head on the nail surface is relatively large or the grinding head is tilted to a certain extent, it will not cause damage to the real nail part. In addition, the setting of the installation component can enable the rotatable connection between the rotating grinding head and the non-rotating base, and can limit the unnecessary shaking of the grinding head during the grinding process.

[0020] It should be understood that the content described in this part is not intended to identify the key or important features of the embodiments of the present disclosure, nor is it used to limit the scope of the present disclosure. Other features of the present disclosure will become easily understood through the following description of the specification. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] By reading the detailed description of the non-limiting embodiments with reference to the following drawings, other features, objects, and advantages of the present disclosure will become more apparent: Figure 1 Schematic structural diagram of a grinding tool provided by an embodiment of the present disclosure; Figure 2 Exploded structural diagram of the grinding tool according to the first embodiment provided by the embodiment of the present disclosure; Figure 3a [[ID=2**]]And Figure 3b Specific structural diagram of the grinding tool according to the first embodiment provided by the embodiment of the present disclosure; Figure 4 An exploded structural diagram of the grinding tool according to the second embodiment provided by the embodiment of the present disclosure; Figure 5 Another exploded structural diagram of the grinding tool according to the second embodiment provided by the embodiment of the present disclosure; Figure 6a And Figure 6b Specific structural diagram of the grinding tool according to the second embodiment provided by the embodiment of the present disclosure; Figure 7 Schematic structural diagram of the grinding tool provided by the embodiment of the present disclosure when grinding the photocuring glue on the nail surface; Figure 8 Flowchart of the formation method of the grinding tool provided by the embodiment of the present disclosure. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The exemplary embodiments of the present disclosure will be described below with reference to the accompanying drawings. Although various detailed descriptions are provided in these embodiments for ease of understanding, those of ordinary skill in the art should understand that these embodiments and their detailed descriptions are merely exemplary, and various modifications can be made to these embodiments without departing from the teachings of the present disclosure. Similarly, for clarity and conciseness, the following description will omit the detailed descriptions of well-known functions and structures. In addition, the embodiments in the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0023] Current nail grinding tools rely on manual operation when grinding photocuring glue, making it difficult to ensure the grinding accuracy and prone to uneven grinding, which affects the nail art effect. In addition, the stability of current nail grinding tools is poor, and they may shake during the grinding process, not only reducing the grinding efficiency but also possibly damaging the nails.

[0024] Based on the problems existing in current nail grinding tools, such as poor stability, possible shaking during the grinding process, low grinding efficiency, and the grinding process may damage the nails, etc., the present disclosure provides a new grinding tool for nail art to enhance the stability during the grinding process, reduce the shaking during the grinding process, and improve the grinding efficiency and safety.

[0025] The present disclosure provides a grinding tool, including a driving member, a grinding head, a base, and a mounting assembly. The driving member is used to drive the grinding head to rotate. The grinding head is connected to the driving member and rotates under the drive of the driving member. The base is located at one end of the grinding head away from the driving member, and the base does not rotate with the grinding head when the grinding head grinds the object to be ground. The mounting assembly is used to rotatably mount the base to the grinding head.

[0026] It should be noted that the object to be ground can be the photocuring glue on the nail surface. Before grinding, a hole can be drilled in the photocuring glue at a selected position on the nail surface, so that the base 14 and the lower part of the grinding head 13 can extend into the hole during subsequent grinding to achieve the abutment of the base with the nail surface during grinding. The outer wall surface of the grinding head can be used as the grinding surface, and the grinding surface of the grinding head can grind the photocuring glue on the nail surface. In addition, before grinding, the photocuring glue at a selected position can also be ground with the grinding surface of the grinding head to expose the nail surface to achieve the abutment of the base with the nail surface during grinding.

[0027] It should be noted that when the grinding surface of the grinding head grinds the photocuring glue on the nail surface, the base does not rotate with the grinding head. The non-rotating base can be rotatably connected to the rotating grinding head through the mounting assembly, and the mounting assembly can limit the unnecessary shaking of the grinding head during the grinding process.

[0028] The grinding tool provided by the present disclosure uses an installation component to realize the rotatable connection between the base and the grinding head. The base does not rotate with the grinding head during the process of the grinding head grinding the object to be ground. For example, when grinding the photocuring glue on the nail surface, the base can be abutted against the nail surface. The setting of the base can improve the safety during the grinding process. Even when the pressure of the grinding head on the nail surface is large, the rotation speed of the grinding head is fast, there are jitters and heat generated during the grinding process, or the grinding head is inclined to a certain extent, the real nail part will not be damaged. In addition, the setting of the installation component can enable the rotatable connection between the rotating grinding head and the non-rotating base, and can limit the unnecessary shaking of the grinding head during the grinding process.

[0029] As Figures 1 to 6b shown, the grinding tool provided by the present disclosure includes a driving member, a grinding head 13, a base 14, and an installation component 15. The driving member is used to drive the grinding head 13 to rotate. The grinding head 13 is connected to the driving member and rotates under the drive of the driving member. The base 14 is located at one end of the grinding head 13 away from the driving member. When the grinding head 13 grinds the object to be ground, the base 14 does not rotate with the grinding head 13. The installation component 15 is used to rotatably install the base 14 on the grinding head 13.

[0030] In some embodiments, as Figures 1 to 6b shown, in the direction of the rotation axis of the grinding head 13, the base 14 protrudes from the grinding head 13, that is, in the Figure 1 vertical direction in, the base 14 protrudes from the grinding head 13. When grinding the photocuring glue on the nail surface, since the base 14 protrudes from the grinding head 13, during the grinding process, the end face of the grinding head 13 close to the nail surface will not directly contact the nail surface, effectively avoiding the chipping of the high-speed rotating grinding head 13 on the nail surface, and also avoiding the heat generated by the high-speed rotating grinding head 13 on the nail surface, thereby improving the user experience.

[0031] Due to the setting of the base in the present disclosure, the shape of the grinding head 13 can be not limited, and the grinding head 13 can be designed in various shapes. Exemplarily, the shape of the grinding head 13 can be cylindrical. Along the rotation axis direction of the grinding head 13 (i.e., along the Figure 1 vertical direction in), the cross-sectional shape of the grinding head 13 can also be rectangular. When using the grinding head 13 to grind the photocuring glue on the nail surface, the corners of the grinding head 13 close to the nail surface are relatively sharp, which is easier to cut into the photocuring glue, thereby improving the grinding efficiency. In addition, during the actual grinding process, due to the setting of the base 14, even if the grinding head 13 runs out of control and drills towards the nail surface, the base 14 can block the grinding head 13, so that the grinding head 13 will not damage the user's nail surface.

[0032] In some embodiments, as Figure 1As shown, the driving member includes a transmission shaft 12 and a power source 11. The transmission shaft 12 and the grinding head 13 can be integrally formed. One end of the transmission shaft 12 away from the grinding head 13 can be connected to the power source 11, and the power source 11 can drive the transmission shaft 12 to rotate. In the present disclosure, a rotatable connection is achieved between the rotating grinding head 13 and the non-rotating base 14 through the mounting assembly 15, which can ensure the smooth sliding of the transmission shaft 12 during rotation.

[0033] It should be noted that the power source 11 can be a motor. Exemplarily, the power source 11 can be a DC servo motor or an AC servo motor.

[0034] Exemplarily, the transmission shaft 12 can be fixed to a jaw capable of high-speed rotation. The transmission shaft 12 can be connected to the motor through the jaw, and the grinding head 13 can achieve high-speed rotation under the drive of the motor. The high-speed rotating grinding head 13 can grind the object to be ground. Exemplarily, the grinding surface of the grinding head 13 can grind the photocuring glue on the nail surface.

[0035] It should be noted that the transmission shaft 12 and the grinding head 13 can also be separately manufactured, and after manufacturing, the transmission shaft 12 and the grinding head 13 can be welded together by, for example, welding.

[0036] It should be noted that in one embodiment, the grinding head 13 can be a solid cylinder. In another embodiment, the grinding head 13 can include two parts. For example, the grinding head 13 includes a first part close to the transmission shaft 12 and a second part away from the transmission shaft 12. The first part can be a hollow structure, and the second part can be a solid structure, that is, the grinding head 13 does not need to adopt a fully solid structure. The first part of the grinding head 13 can adopt a hollow structure, and the second part of the grinding head 13 can adopt a solid structure.

[0037] [[ID=e15]]In some embodiments, as Figures 1 to 6b shown, the grinding surface of the grinding head 13 includes a grinding portion, and the shape of the grinding portion is spiral. When using the grinding head 13 to grind the photocuring glue on the nail surface, the spiral grinding portion is more likely to cut into the photocuring glue, can efficiently discharge the photocuring glue debris generated during grinding, and can closely fit the curvature of the nail surface to achieve precise grinding of the photocuring glue and effectively remove the residual glue.

[0038] Exemplarily, the upper part of the outer wall side of the grinding head 13 can also not be used as the grinding surface, and only the lower part is used as the grinding surface. At this time, the upper part of the outer wall side of the grinding head 13 can be a smooth surface. Of course, the entire outer wall side of the grinding head 13 can be used as the grinding surface. The grinding surface includes a grinding portion, and the grinding portion can be spiral cutting teeth. The spiral directions of multiple spiral cutting teeth can be the same, and the intervals between adjacent spiral cutting teeth can be the same.

[0039] In some embodiments, such as Figure 2 , Figure 3a and Figure 3b shown, the mounting assembly 15 includes a first mounting portion 151 and a second mounting portion 152. The first mounting portion 151 and the second mounting portion 152 are rotatably connected. The first mounting portion 151 is connected to the grinding head 13, and the second mounting portion 152 is connected to the base 14.

[0040] In some embodiments, such as Figure 2 , Figure 3a and Figure 3b shown, the second mounting portion 152 can surround the outer periphery of the first mounting portion 151. Exemplarily, in a plane perpendicular to the rotation axis of the grinding head 13, the cross-sectional shape of the first mounting portion 151 can be circular, and the cross-sectional shape of the second mounting portion 152 can also be circular, and the diameter of the first mounting portion 151 is smaller than the diameter of the second mounting portion 152.

[0041] Exemplarily, the mounting assembly 15 can be a bearing. The first mounting portion 151 can be the inner ring of the bearing, and the second mounting portion 152 can be the outer ring of the bearing. The inner ring and the outer ring of the bearing are rotatably connected. The outer ring of the bearing can be connected to the base 14, and the inner ring of the bearing can be connected to the grinding head 13. The rotatable connection between the base 14 and the grinding head 13 can be achieved through the bearing. The connection between the inner ring and the outer ring of the bearing is realized by the rolling of rolling elements (such as balls and rollers) in the raceway. Herein, the raceway is the surface on the inner ring and the outer ring of the bearing for the rolling elements to roll.

[0042] In some embodiments, such as Figure 2 , Figure 3a and Figure 3b shown, at one end of the grinding head 13 close to the base 14, there are provided a mounting opening 131 and a mounting protrusion 132. The mounting opening 131 is recessed in a direction away from the base 14, and the mounting protrusion 132 is located within the mounting opening 131. The size of the mounting opening 131 is determined to be suitable for accommodating the mounting assembly 15 and the base 14, and the first mounting portion 151 is mounted on the mounting protrusion 132.

[0043] Exemplarily, the grinding head 13 can be a solid structure. A mounting opening 131 can be drilled on the end face of the grinding head 13 close to the base 14, that is, a mounting opening 131 can be drilled on the end face of the grinding head 13 away from the transmission shaft 12. The size of the hole during drilling can be determined according to the sizes of the mounting assembly 15 and the base 14. Exemplarily, in the direction of the rotation axis of the grinding head 13, the size of the mounting opening 131 at the position close to the mounting protrusion 132 is smaller than the size at the position away from the mounting protrusion 132, that is, the mounting opening 131 can be a stepped mounting opening. After the mounting protrusion 132 and the first mounting part 151 are in interference fit, in the direction of the rotation axis of the grinding head 13, there can be a certain gap between the second mounting part 152 and the base 14 and the grinding head 13, so as to better ensure that the second mounting part 152 and the base 14 do not rotate with the grinding head 13.

[0044] Exemplarily, when drilling the end face of the grinding head 13 close to the base 14, the drilling force at the middle position of the grinding head 13 can be less than the drilling force at the edge position, so that a mounting protrusion 132 is formed at the middle position. Exemplarily, the mounting assembly 15 is a bearing, and the size of the mounting protrusion 132 can be set according to the size of the inner ring of the bearing. The formed mounting protrusion 132 can be adapted to the inner ring of the bearing, so that the inner ring of the bearing can be mounted on the mounting protrusion 132.

[0045] Exemplarily, the mounting protrusion 132 and the first mounting part 151 can be connected by welding. Additionally, an external thread can be formed on the outer wall of the mounting protrusion 132, and an internal thread can be formed on the inner wall of the first mounting part 151. The mounting protrusion 132 and the first mounting part 151 can be connected by screw threads.

[0046] Exemplarily, the base 14 can include a base connection part 141 and a base opening 142. The base connection part 141 can be connected to the second mounting part 152. For example, the base connection part 141 and the second mounting part 152 can be connected by welding. Additionally, the base opening 142 can also be in interference fit with the second mounting part 152 to realize the connection between the base connection part 141 and the second mounting part 152.

[0047] In some embodiments, as Figure 4 、 Figure 5 、 Figure 6a and Figure 6b shown, the mounting assembly 15 includes a first part 151 and a second part 152 that are fixedly connected. The extending direction of the first part 151 is along the rotation axis direction of the grinding head 13, that is, the extending direction of the first part 151 is along Figure 6b the vertical direction, and the extending direction of the second part 152 is perpendicular to the extending direction of the first part 151, that is, the extending direction of the second part 152 is along Figure 6bIn the horizontal direction. Among them, the first part 151 is connected to the grinding head 13, and the second part 152 is rotatably connected to the base 14. In the direction perpendicular to the direction of the rotation axis of the grinding head 13, the size of the first part 151 is smaller than that of the second part 152, and a step is formed at the connection position between the first part 151 and the second part 152.

[0048] Exemplarily, the mounting component 15 can adopt a screw, and the screw is fixedly connected to the grinding head 13.

[0049] In some embodiments, such as Figure 6b shown, the base 14 includes a first opening 141 and a second opening 142. In the direction perpendicular to the direction of the rotation axis of the grinding head 13 (i.e., Figure 6b the horizontal direction in Figure 6b ), the size of the first opening 141 is smaller than that of the second opening 142, and the stepped opening formed by the first opening 141 and the second opening 142 penetrates the base along the extension direction of the grinding head 13 (i.e., along the

[0050] vertical direction in

[0051] In some embodiments, such as Figure 6b shown, at one end of the grinding head 13 close to the base 14, a first mounting structure 133 and a second mounting structure 134 are provided. The first part 151 passes through the first opening 141 and the second opening 142 and is fixedly connected to the first mounting structure 133. The second mounting structure 134 is adapted to the base 14, and there can be a clearance fit between the base 14 and the grinding head 13.

[0052] Exemplarily, the first mounting structure 133 can be a threaded hole, and the second mounting structure 134 can be a mounting groove surrounding the first mounting structure 133, and the mounting groove is concave in the direction away from the base 14. For example, the first mounting structure 133 and the second mounting structure 134 can be formed by drilling holes in the end face of the grinding head 13 close to the base 14.

[0053] It should be noted that the second mounting structure 134 being adapted to the base 14 can mean that the base 14 can be installed in the second mounting structure 134.

[0054] Exemplarily, internal threads may be formed on the surface of the first mounting structure 133, and external threads may be formed on the first part 151. The first mounting structure 133 and the first part 151 may be fixedly connected by means of threaded connection. After the first mounting structure 133 and the first part 151 are fixedly connected, the base 14 with a stepped opening may abut against the step at the connection position between the first part 151 and the second part 152. In the direction of the rotation axis of the grinding head 13, the second part 152 may prevent the base 14 from falling off.

[0055] It should be noted that the base 14 may be made of a smooth wear-resistant material. For example, the material of the base 14 may be polytetrafluoroethylene (PTFE).

[0056] Exemplarily, during the grinding process, the lower surface of the base 14 abuts against the nail surface, and the upper surface of the base 14 contacts the grinding head 13. The upper surface of the base 14 may be ground to make the upper surface of the base 14 smooth. The frictional force on the upper surface of the base 14 may be less than the frictional force on its lower surface. Furthermore, during the grinding process, the base 14 may not rotate, and the mounting assembly rotates with the grinding head 13.

[0057] In some embodiments, the grinding tool may further include a washer 16, and the washer 16 may be disposed on the surface of the base 14 facing the grinding head 13.

[0058] It should be noted that the washer 16 may be made of a smooth wear-resistant material. For example, the material of the washer 16 may be PTFE. In a specific embodiment, the material of the washer 16 may be the same as the material of the base 14. Of course, the material of the washer 16 may also be different from the material of the base 14. When the materials of the two are different, the material of the washer 16 may be selected to be more wear-resistant and have a smaller frictional force than the material of the base 14.

[0059] Exemplarily, the washer 16 may be disposed on the upper surface of the base 14. For example, a thin sheet of smooth PTFE material may be selected, and a through hole penetrating the thin sheet may be formed at the middle position of the thin sheet. The size of the through hole may be the same as the size of the first opening 141, or the size of the through hole may be slightly larger than the size of the first opening 141. Then, the thin sheet with the through hole may be sleeved on the base 14. The specific size of the thin sheet may be set according to the actual design, as long as it is ensured that the thin sheet can cover part or all of the upper surface of the base 14.

[0060] Exemplarily, the base 14 and the grinding head 13 can be assembled with a gap, that is, there can be a certain gap between the side surface of the base 14 and the grinding head 13. For example, in the direction perpendicular to the extension direction of the grinding head 13, the size of the second mounting structure 134 is larger than the size of the base 14. At this time, the side surface of the base 14 does not contact the grinding head 13, which can improve the smoothness of the rotation of the base 14 and the grinding head 13.

[0061] Exemplarily, at the stepped opening position formed by the first opening 141 and the second opening 142, the base 14 forms stepped portions on both sides of the stepped opening. The second portion 152 abuts against the stepped portion of the base 14. In the direction of the rotation axis of the grinding head 13, the second portion 152 can prevent the base 14 from falling off.

[0062] The grinding tool in the present disclosure can be integrated with a robotic arm to achieve automatic grinding, or can be manually ground by a manicurist operating the grinding tool.

[0063] Taking the photocuring glue on the nail surface as an example of the object to be ground in the present disclosure, the specific working process of the grinding tool in the present disclosure will be described in detail below.

[0064] Before grinding the photocuring glue 22 on the nail surface 21, the photocuring glue at a selected position on the nail surface can be drilled so that the base 14 and the lower part of the grinding head 13 can extend into the hole during subsequent grinding.

[0065] When starting the grinding tool to grind the photocuring glue 22 on the nail surface 21, the transmission shaft 12 starts to rotate under the drive of the power source 11, and then can drive the grinding head 13 to rotate. The manicurist or the automatic manicure device brings the grinding tool close to the nail surface and aligns it with the position of the hole drilled in the photocuring glue before, so that the base 14 and the lower part of the grinding head 13 can abut against the nail surface 21. As Figure 7 shown, there is a certain gap between the grinding head 13 and the nail surface 21, and the lower part of the grinding head 13 can be used to grind the photocuring glue 22. The non-rotating base 14 is rotatably connected to the grinding head 13 through the mounting assembly. During the grinding process, the non-rotating base 14 can improve the safety during the grinding process. Even if the pressure of the grinding head on the nail surface is large or the grinding head is tilted to a certain extent, it will not cause damage to the real nail part. And the non-rotating base 14 can provide stable support for the entire grinding tool, making the grinding process proceed smoothly. And the setting of the mounting assembly can ensure the stability of the transmission shaft 12 during rotation. When grinding the photocuring glue 22, since there is a certain gap between the grinding head 13 and the nail surface 21, the heat generated by the high-speed rotation of the grinding head 13 on the nail surface can be reduced, and thus the customer experience can be improved. In addition, the grinding tool in the present disclosure reduces the skill requirements for the manicurist's operation and can also be integrated with an automatic nail grinding machine.
