Description

Technology Field

[0001] The present invention relates to an auxiliary tool for pin coupling that assists in precisely coupling a pin to an object of a different diameter and a pin coupling method using the same. More specifically, the invention relates to an auxiliary tool for simple pin coupling and a pin coupling method using the same, wherein the tool is structured such that a hole of a set diameter for temporarily fixing the object and a hole that guides an accurate vertical path for the pin to enter the upper center of the object are interconnected to assist in the mutual coupling between the object and the pin, and in particular, the tool actively suppresses the movement of the pin vertically intervening above the temporarily fixed object to maximize the precision of the coupling between the object and the pin, thereby maximizing convenience or efficiency of use due to ease of handling, use, maintenance, and repair resulting from a structure differentiated from existing ones. Background Technology

[0003] Typically, when connecting or joining pins to objects of different diameters, the process is carried out by holding and fixing the object with one hand and grasping the pin with the other hand to insert it into a hole formed at one end of the object.

[0004] This method is mainly used in tooth polishing handpieces that use a grinding stone directly attached to a shank.

[0006] For example, regarding technology related to a handpiece for polishing teeth, Registered Patent Publication No. 10-2085108, "Dental groove bur capable of polishing at various angles," is disclosed, and the technology comprises a head part for polishing teeth; and a connecting part to which one end is connected to the head part and the other end is connected to a dental handpiece.

[0007] In particular, the head portion is formed with a polygonal shape and is composed of a body that is sharply formed; and a plurality of protrusions arranged at set intervals on the outer circumference of the body; and due to this structure, the tooth can be polished into various shapes suitable for the procedure with only a single groove bur, thereby maximizing efficiency during implant surgery.

[0009] Another technology similar or identical to the above technology is disclosed in Korean Patent Publication No. 10-2013-0035347, "Rotary Grinding Tool for Dental Use," which enables the convenient formation of the margin of an abutment tooth for crown prosthetic treatment to restore the external shape of a damaged tooth, while also allowing the margin shape to be accurately formed by a single tool.

[0010] The above prior art is based on a dental grinding tool that is provided in a rod shape having a certain length and has a grinding stone at its tip for grinding teeth and removing a portion thereof. In particular, the grinding tool comprises a body having a straight section that is extended to have a certain diameter; and a protruding tip formed integrally to protrude from the end of the body, formed in a rounded state from the end of the straight section. Here, the protruding tip has a structure consisting of a curved section rounded from the end of the straight section of the body and an inclined straight section extending from the curved section to the tip.

[0011] According to the above-described prior art having such a structure, when removing a tooth with a round end bur, the formation of an enamel layer is prevented, and at the same time, a separate additional step to remove the enamel layer is eliminated, thereby shortening the procedure time. In addition, it prevents the shortening of the lifespan of the prosthesis due to the enamel layer, and at the same time, the tooth can be polished into various shapes with only a single tool, making it highly efficient during implant procedures.

[0013] Meanwhile, grinding stones attached to dental handpieces are classified into products in which the shank and grinding stone are integrated, and products in which the user assembles the shank and grinding stone themselves. In the case of products where the user assembles the shank and grinding stone themselves, the user must hold and secure the grinding stone with one hand and hold the shank with the other hand, inserting it precisely into the center of one end of the grinding stone.

[0014] However, with the artificial joining method described above, it is difficult to assemble the shank to align with the precise vertical line of the grinding stone, and this problem causes vibration in the handpiece, making precise grinding impossible.

[0015] Therefore, there is a pressing need for a tool that can easily and conveniently align objects and pins of different diameters, such as the shank of a handpiece and a grinding stone, on an accurate vertical line. Prior art literature

[0017] Registered Patent Publication No. 10-2085108 "Dental groove bur capable of grinding at various angles" Published Patent Publication No. 10-2013-0035347 "Dental rotary grinding tool" The problem to be solved

[0018] The present invention was created to more actively resolve the aforementioned problems, and the main objective is to provide an auxiliary tool that can easily, conveniently, and precisely combine objects and pins of different diameters by aligning them on the same vertical line.

[0020] In addition, another problem addressed by the present invention is to provide an auxiliary tool that allows for more convenient assembly of an object and a pin by configuring the structure to stand upright on its own, and which has a very simple overall structure that facilitates manufacturing and storage.

[0022] In addition, another problem addressed by the present invention is to provide an auxiliary tool with a structure capable of actively preventing damage to an object or a pin caused by external force during the process of assembling the object and the pin. means of solving the problem

[0024] To achieve the above-mentioned problem, the auxiliary tool for simple pin coupling and the pin coupling method using the same proposed in the present invention are as follows.

[0026] The auxiliary tool of the present invention is characterized by allowing vertical intervention of an object (1) at the bottom to temporarily fix it, and allowing vertical intervention of a pin (2) with a diameter smaller than that of the object at the top to guide a path so as to be coupled to the upper surface of the object, wherein the movement of the object and the pin is suppressed through the insertion path of the temporarily fixed object and the pin, thereby inducing a precise coupling between them.

[0028] Additionally, the auxiliary tool of the present invention comprises: a body (10) having an external shape that is easy to stand on its own and has a set length; a fixing hole (20) formed by being recessed to a set depth from the bottom surface of the body to allow the intervention of an object (1); and a coupling hole (30) that is vertically penetrated from the top surface of the body to the fixing hole and has a diameter smaller than that of the fixing hole to guide the insertion path of a pin (2).

[0030] Additionally, the fixed hole (20) and the coupling hole (30) are configured as at least one within the range allowed by the body (10).

[0032] In addition, the pin coupling method using the auxiliary tool of the present invention is characterized by comprising: a target object restraint step (S10) in which a target object (1) is inserted into a fixing hole (20) and a body is placed on the ground; a pin coupling step (S20) in which a pin (2) is inserted into a coupling hole (30) and a pin exposed above the body is struck vertically to connect the pin to the target object; and an auxiliary tool removal step (S30) in which the target object with the pin connected is pushed into the fixing hole to be separated. Effects of the invention

[0034] According to the present invention, which is configured as described above, the object is temporarily restrained by a fixing hole so that movement is completely suppressed during assembly, and the pin is temporarily restrained in the lateral direction by a coupling hole so that movement is suppressed during assembly, thereby enabling the pin to be assembled precisely on a vertical line at the upper center of the object.

[0036] In addition, the present invention has another effect of minimizing damage to the object or pin even when the pin is struck vertically to insert it into the object, because the auxiliary tool protects the object and the pin, such as when assembly is performed with the object and the pin fully or partially inserted into the auxiliary tool.

[0039] Hereinafter, the structure of the present invention and the resulting operation and effects will be described collectively with reference to the attached drawings.

[0041] The advantages and features of the present invention and the methods for achieving them will become clear by referring to the embodiments described below in detail together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but can be implemented in various different forms. These embodiments are provided merely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims. Furthermore, throughout the entire specification, the same reference numerals refer to the same components.

[0043] The present invention relates to an auxiliary tool for pin joining that assists in precisely joining a pin to an object of a different diameter and a pin joining method using the same.

[0045] Above all, the present invention relates to an auxiliary tool for simple pin coupling and a pin coupling method using the same, wherein the tool is structured such that a hole of a set diameter for temporarily fixing an object and a hole guiding a pin to enter the upper center of the object are interconnected to assist in the mutual coupling between the object and the pin, and particularly, the tool actively suppresses the movement of the pin vertically intervening above the temporarily fixed object to maximize the precision of the coupling between the object and the pin, thereby maximizing convenience or efficiency of use due to ease of handling, use, maintenance, and repair derived from a structure differentiated from existing ones.

[0047] FIG. 1 is a perspective view of an auxiliary tool configured according to a preferred embodiment of the present invention, FIG. 2 is a cross-sectional view of an auxiliary tool proposed by the present invention, FIG. 3 to 5 are state diagrams sequentially showing the process of joining an object and a pin using the auxiliary tool of the present invention, and FIG. 6 is a flowchart showing the process of joining a pin using the auxiliary tool of the present invention in steps.

[0049] Before describing the present invention, the object (1) may have a cylindrical shape, with a diameter of about 7 to 8 mm and a length of about 25 to 27 mm. The pin (2) may have a cylindrical shape similar to the object (1), with a diameter of about 2 to 3 mm and a length of about 25 to 30 mm.

[0050] In particular, according to one embodiment of the present invention, the object (1) may be a grinding stone used in a dental handpiece, and the pin (2) may be a shank used in a dental handpiece.

[0052] The configuration of the auxiliary tool for easy pin coupling of the present invention is as follows.

[0053] First, the bottom allows for the vertical insertion of the object (1) to be temporarily fixed, and the top allows for the vertical insertion of a pin (2) with a diameter smaller than that of the object, thereby guiding the path so that the pin can be inserted and restrained in a precise vertical position at the center of the upper surface of the object. The object (1) and the pin (2), thus temporarily fixed, have their movement suppressed through their respective inserted paths, allowing for precise assembly between them.

[0055] As shown in FIG. 1, the auxiliary tool for easy pin coupling of the present invention has the following detailed structure.

[0056] The above auxiliary tool comprises: a body (10) having an external shape that is easy to stand on its own and has a set length; a fixing hole (20) formed by being recessed to a set depth from the bottom surface of the body to allow the intervention of an object (1); and a coupling hole (30) that is vertically penetrated from the top surface of the body to the fixing hole and has a diameter smaller than that of the fixing hole to guide the insertion path of a pin (2).

[0057] As described above, the auxiliary tool proposed by the present invention is composed of a rod-shaped body (10), a counter bore fixing hole (20) and a coupling hole (30) on the body, and assists in enabling precise assembly between an object (1) and a pin (2).

[0058] The above body (10) may be formed in the shape of a cylinder with a set diameter, or in the shape of a triangular prism, or in the shape of a polygonal prism including a square prism.

[0059] The above body (10) has a vertical length set so that a part of the pin (2) can be inserted while the object (1) is fully accommodated, and according to a preferred embodiment of the present invention, it can be configured to be about 35 to 45 mm.

[0061] The above fixing hole (20) is formed by being recessed to a set depth from the bottom surface of the body (10). This fixing hole (20) is formed with a diameter that corresponds one-to-one with the object (1), and according to an embodiment of the present invention, it may be formed with a diameter of about 6 to 8 mm and may be formed by being recessed to a depth of about 24 to 26 mm starting from the bottom surface of the body (10).

[0062] These fixing holes (20) contribute to the temporary fixation of the object (1) by allowing its insertion, and also completely prevent movement to the left and right during the assembly process with the pin. Subsequently, they also serve to provide a position so that the pin (2), which is inserted through the coupling hole (30) formed on the upper part of the body (10), can be placed in the exact center of the upper surface of the object (1) during assembly.

[0064] The above coupling hole (30) is formed vertically through the upper surface of the body (10) to the fixing hole (20). This coupling hole (30) is formed with a diameter that corresponds one-to-one with the pin (2), and according to a preferred embodiment of the present invention, it may be formed with a diameter of about 2 to 3 mm.

[0065] Additionally, the coupling hole (30) has an entry surface into which the pin (2) is inserted that is chamfered in a tapered shape to provide convenience for the pin to be inserted more effectively. This coupling hole (30) allows the insertion of the pin (2) and, at the same time, provides a vertical path so that the pin can enter the object (1) received in the fixing hole (20) exactly vertically. In addition, it guides the pin (2) to an accurate entry path so that it does not enter in a tilted or eccentric direction while reaching the object (1).

[0067] For example, when assembling a pin (2) to the end of an object (1), the pin is placed on the upper surface of the object and the end of the pin is struck several times to insert it into the object. Here, since the object (1) is made of a cylinder with a diameter of about 6 to 8 mm and the pin (2) is made of a cylinder with a diameter of about 2 to 3 mm, problems may occur in which the pin bends or the pin or the object is damaged during the process of striking the pin.

[0068] However, since the auxiliary tool of the present invention completely accommodates the object (1) in the fixing hole (20) of the body (10) and strikes the pin (2) in the coupling hole (30), it can actively prevent bending or damage that occurs during the process of coupling the object and the pin.

[0070] In addition, the auxiliary tool of the present invention may assemble multiple objects and pins at once by configuring at least one fixing hole (20) and a coupling hole (30) within the range allowed by the body (10).

[0072] As shown in FIG. 6, the pin coupling method using the auxiliary tool of the present invention is as follows.

[0073] The pin coupling method using the auxiliary tool of the present invention may be composed of: a target body restraint step (S10) in which a body (10) is inserted while the target body (1) is inserted into the fixing hole (20) of the auxiliary tool; a pin coupling step (S20) in which a pin (2) is inserted into the coupling hole (30) and then the pin exposed above the body is struck vertically to retract the pin into the interior of the target body; and an auxiliary tool removal step (S30) in which the target body with a portion of the pin retracted is removed from the fixing hole and separated.

[0075] According to the auxiliary tool of the present invention configured as described above, the object is temporarily restrained by a fixing hole so that movement is completely suppressed during assembly, and the pin is temporarily restrained in the lateral direction by a coupling hole so that movement is suppressed during assembly, thereby allowing the pin to be assembled precisely on a vertical line at the upper center of the object.

[0076] In addition, since the auxiliary tool protects the object and the pin, such as when assembly is performed with the object and the pin fully or partially inserted into the auxiliary tool, damage to the object or the pin can be minimized even if the pin is struck vertically to insert it into the object.

[0078] The present invention described above has been explained with reference to an exemplary embodiment illustrated in the drawings, but this is merely illustrative, and it should be made clear to those skilled in the art that various modifications and equivalent alternative embodiments are possible therefrom. Accordingly, the true technical scope of protection of the present invention should be interpreted by the appended claims, and all technical ideas within an equivalent scope should be interpreted as being included within the scope of rights of the present invention.
