Abstract
Description
[Technical field]
[0001] The present disclosure relates to a screw locking tool. [Background technology]
[0002] To prevent the bolts from loosening, a thread locking agent is applied to the bolts before they are tightened.
[0003] 10 is a diagram illustrating a conventional application process of a thread locking agent to a bolt. The thread locking agent is contained in, for example, a resin container 2000, and an operator applies the thread locking agent to the periphery of the threaded portion 1100 of a bolt 1000 while squeezing the agent out of the container 2000. Summary of the Invention [Problem to be solved by the invention]
[0004] However, in order to apply the thread locking agent to the entire circumference of the threaded portion, the worker must rotate the container 2000 around the threaded portion 1100 while pushing out the thread locking agent from the container 2000. Therefore, when there are many bolts 1000, the work takes time. Also, there is variation in the application of the thread locking agent between the bolts 1000.
[0005] An object of the present disclosure is to provide a screw locking jig that is capable of reducing variation and improving work efficiency. [Means for solving the problem]
[0006] The thread locking jig according to the first disclosure comprises a placement portion, a first recess, a fluid flow path, and a plurality of first openings. An outlet of a container containing a liquid for thread locking is placed in the placement portion. The threaded portion of a bolt is inserted from its tip into the first recess. A liquid flow path is formed from the placement portion to the periphery of the recess. The plurality of first openings are formed on the inner surface of the recess and are connected to the liquid flow path. Effect of the Invention
[0007] According to the present disclosure, it is possible to provide a screw locking jig that can reduce variation and improve work efficiency. [Brief description of the drawings]

[0009] Hereinafter, a screw locking jig according to an embodiment of the present disclosure will be described with reference to the drawings.
[0010] (Overview of screw lock jig 1) Fig. 1(a) is a perspective view of a screw locking jig 1 according to an embodiment, and Fig. 1(b) is a perspective view showing a state in which a container 2 containing a screw locking agent is attached to the screw locking jig 1.
[0011] The thread locking jig 1 is used when applying a thread locking agent to the threads of a bolt. The thread locking agent is applied around the threads of the bolt to prevent the bolt from loosening. As shown in FIG. 1(b), the thread locking jig 1 is attached to a container 2 containing the thread locking agent.
[0012] Fig. 2 is a front cross-sectional view of the screw locking jig 1. Fig. 3 is a front cross-sectional view of the screw locking jig 1 with the container 2 attached. Fig. 4A is a cross-sectional view of the screw locking jig 1 in a state in which a thread locking agent is being applied to the threads of a bolt.
[0013] As shown in Fig. 2, the screw locking jig 1 includes a placement section 20, a screw insertion section 30, a liquid flow path 40, and a plurality of openings 34a. As shown in Fig. 3, a cap section 52 of a container 2 containing a thread locking agent is placed in the placement section 20. As shown in Fig. 4A, a threaded section 61 of a bolt 60 is inserted into the screw insertion section 30. As shown in Fig. 2, the liquid flow path 40 is formed from the placement section 20 to the periphery of the screw insertion section 30. The plurality of openings 34a are formed on an inner surface 31c of the screw insertion section 30. The plurality of openings 34a are connected to the liquid flow path 40.
[0014] When an operator holds the container 2 and applies pressure to the container 2, the thread locking agent is discharged from the protruding portion 54a (described later) of the cap portion 52. The discharged thread locking agent moves toward the multiple openings 34a through the liquid flow path 40 (see the arrows in FIG. 4A). The thread locking agent discharged from the openings 34a spreads in the gap G between the screw insertion portion 30 and the threaded portion 61 due to the pressure of the discharge, and is applied to a predetermined number of threads, leaving one or two threads from the tip 61a of the threaded portion 61. FIG. 4B is a diagram showing a bolt 60 in a state in which the thread locking agent has been applied. The thread locking agent H covers a predetermined number of threads, leaving one or two threads from the tip 61a of the threaded portion 61. For example, in the case of a bolt of M12 or less, it is preferable to apply the thread locking agent so as to cover three or four threads, leaving one or two threads from the tip 61a. In addition, in the case of a bolt of M14 or more, it is preferable to apply the thread locking agent so as to cover 7 to 8 threads, leaving 1 to 2 threads from the tip 61a.
[0015] 2, the screw locking jig 1 of the present embodiment is formed by combining an outer member 11 (an example of a first member) and an inner member 12 (an example of a second member). The inner member 12 is inserted into the outer member 11. The outer member 11 includes the arrangement portion 20 described above. The inner member 12 includes a screw insertion portion 30 and a plurality of openings 34a. A liquid flow path 40 is formed between the outer member 11 and the inner member 12.
[0016] (Outer member 11) Fig. 5(a) is a perspective view of the outer member 11. Fig. 5(b) is a front cross-sectional view of the outer member 11.
[0017] As shown in Fig. 5(a), the outer member 11 has a generally cylindrical outer shape. As shown in Fig. 5(b), the outer member 11 has a cylindrical portion 21 (an example of a first cylindrical portion), a wall portion 22, an inner member insertion portion 23 (an example of a second recess), an inner protruding portion 24, and an outer protruding portion 25.
[0018] The cylindrical portion 21 is a cylindrical member with both ends open. The cylindrical portion 21 has an end 21a (an example of a first end) and an end 21b (an example of a second end). In Fig. 5(b), a central axis A of the cylindrical portion 21 is shown.
[0019] As shown in Fig. 5(b), the wall portion 22 is disposed inside the cylindrical portion 21. The wall portion 22 is disposed between the ends 21a and 21b of the cylindrical portion 21. The wall portion 22 is disposed along a direction perpendicular to the central axis A of the cylindrical portion 21. In the present embodiment, the wall portion 22 is disposed closer to the end 21a than to the end 21b of the cylindrical portion 21. A through hole 26 is formed in the center of the wall portion 22 along the central axis A of the cylindrical portion 21.
[0020] The above-mentioned arrangement portion 20 is formed by the wall portion 22 and a portion 211 (an example of a second portion) of the cylindrical portion 21 from the wall portion 22 to the end 21a. The arrangement portion 20 is formed in a shape recessed in a direction along the central axis A. As shown in FIG. 4A, a cap portion 52 fits into the arrangement portion 20. As shown in FIG. 5(b), the through hole 26 of the wall portion 22 has an opening 26a on a surface 22a of the wall portion 22 facing the arrangement portion 20. The surface 22a forms the bottom surface of the arrangement portion 20.
[0021] As shown in Fig. 2, the inner member 12 is inserted into the inner member insertion portion 23 along the central axis A. The inner member insertion portion 23 is formed in a shape recessed in a direction along the central axis A. As shown in Fig. 5(b), the inner member insertion portion 23 is formed by a portion 212 (an example of a first portion) of the cylindrical portion 21 from the wall portion 22 to the end 21b, and the wall portion 22. The through hole 26 has an opening 26b in a surface 22b of the wall portion 22 facing the inner member insertion portion 23. The arrangement portion 20 and the inner member insertion portion 23 are arranged with the wall portion 22 sandwiched therebetween.
[0022] As shown in Fig. 5(b), the inner protrusion 24 is disposed around the entire circumferential circumference at the end 21b of the cylindrical portion 21. The inner protrusion 24 protrudes toward the inside in the radial direction of the cylindrical portion 21. As shown in Fig. 2, in a state in which the outer member 11 and the inner member 12 are combined, the inner protrusion 24 protrudes toward the inner member 12.
[0023] 5(b), the outer protrusion 25 is disposed around the entire circumference in the circumferential direction at the end 21b of the cylindrical portion 21. The outer protrusion 25 protrudes toward the outside in the radial direction of the cylindrical portion 21. The outer protrusion 25 is disposed opposite to the inner protrusion 24 with the cylindrical portion 21 in between.
[0024] (Inner member 12) Fig. 6(a) is a perspective view of the inner member 12. Fig. 6(b) is a front cross-sectional view of the inner member 12. Fig. 6(c) is a plan cross-sectional view of the inner member 12. Fig. 6(c) is a cross-sectional view taken along the arrow CC' in Fig. 6(b).
[0025] As shown in Fig. 2, the inner member 12 is inserted into the inner member insertion portion 23 of the outer member 11. As shown in Fig. 6(a) and Fig. 6(b), the inner member 12 has a cylindrical portion 31, a lid portion 32, and an outer protruding portion 33.
[0026] The cylindrical portion 31 is cylindrical. As shown in Fig. 6(b), the cylindrical portion 31 has two ends, an end 31a (an example of a third end) and an end 31b (an example of a fourth end). A central axis B of the cylindrical portion 31 is shown.
[0027] A plurality of through holes 34 are formed in the cylindrical portion 31. As shown in FIG. 6(b), the plurality of through holes 34 have openings 34a on the inner side surface 31c of the cylindrical portion 31 and openings 34b on the outer side surface 31d. As shown in FIG. 6(c), the plurality of through holes 34 are provided at equal angular intervals along the circumferential direction when viewed along the central axis B. In this embodiment, four through holes 26 are provided in the cylindrical portion 31 at 90 degree intervals. Each of the through holes 26 is formed along a direction perpendicular to the central axis B.
[0028] The multiple through holes 34 are arranged at the same position in the direction along the central axis B. That is, the multiple through holes 34 have the same length to the end 31a in the direction along the central axis B. The multiple through holes 34 are provided at a position closer to the end 31b side than to the end 31a in the cylindrical portion 31. The inner diameter of the through holes 34 can be set to 1 to 3 mm. Although four through holes 34 are provided as shown in Figures 6(a) to 6(c), for example, three through holes 34 may be provided at intervals of 120 degrees.
[0029] The lid portion 32 is disposed so as to close the end 31a of the tubular portion 31. The lid portion 32 and the inner member 12 form a cylindrical shape with a bottom. The lid portion 32 is disposed perpendicular to the central axis B.
[0030] The above-mentioned screw insertion portion 30 is formed by the cylindrical portion 31 and the lid portion 32. The threaded portion 61 of the bolt 60 is inserted into the screw insertion portion 30 (see FIG. 4A). The screw insertion portion 30 is formed in a shape concave in a direction along the central axis B. A surface 32a (see FIG. 6(a)) on the end 31b side of the lid portion 32 forms the bottom of the concave screw insertion portion 30. An inner surface 31c of the cylindrical portion 31 forms the inner surface of the screw insertion portion 30.
[0031] 6(b), the outer protrusion 33 is disposed around the entire circumferential direction at the end 31b of the cylindrical portion 31. The outer protrusion 33 protrudes outward in the radial direction of the cylindrical portion 31.
[0032] (Combination of outer member 11 and inner member 12) As shown in Fig. 2, the inner member 12 is inserted into the inner member insertion portion 23 of the outer member 11 from the end 31a side of the tubular portion 31. A central axis A of the outer member 11 and a central axis B of the inner member 12 coincide with each other. Here, the tubular portion 21 and the inward protruding portion 24 of the outer member 11 are bonded to the outward protruding portion 33 of the inner member 12 by an adhesive over the entire circumference (bonding portion D1 in Fig. 2), and the inward protruding portion 24 of the outer member 11 is bonded to the tubular portion 31 of the inner member 12 by an adhesive over the entire circumference (bonding portion D2 in Fig. 2).
[0033] By inserting the inner member 12 into the outer member 11, the lid portion 32 of the inner member 12 faces the wall portion 22 of the outer member 11 with a predetermined gap therebetween. A predetermined space S1 is formed between the wall portion 22 of the outer member 11 and the lid portion 32 of the inner member 12.
[0034] In addition, the outer peripheral surface of the tubular portion 31 of the inner member 12 and the inner peripheral surface of the tubular portion 21 of the outer member 11 face each other with a predetermined gap therebetween. A predetermined space S2 is formed between the tubular portion 31 of the outer member 11 and the tubular portion 21 of the inner member 12. As shown in Fig. 2, the opening 34b of the through hole 34 faces the space S2.
[0035] A liquid flow path 40 through which the thread locking agent flows is formed by the through hole 26, the space S1, and the space S2. The liquid flow path 40 connects the placement portion 20 and the through hole 34 that includes an opening 34a to the screw insertion portion 30.
[0036] 2, the position of an edge 34e of the multiple through holes 34 in the inner member 12 on the end 31b side coincides with the position of an edge 24e of the inward protruding portion 24 on the end 21a side of the outer member 11. The through holes 34 are provided at the end of the space S2 opposite to the space S1.
[0037] With this configuration, the thread locking agent that flows into through hole 26 from opening 26a flows into space S1 from opening 26b. The thread locking agent that flows into space S1 flows into space S2, passes through through hole 34, and is discharged into screw insertion portion 30 from opening 34a.
[0038] (Attachment of container 2 to screw lock jig 1) FIG. 7(a) is a perspective view of container 2 containing a thread locking agent. Container 2 is made of, for example, resin. Container 2 has container body 51 and cap portion 52. Container body 51 contains thread locking agent. Cap portion 52 is attached to container body 51. Cap portion 52 has cap body 53 and protrusion 54. Cap body 53 is the portion of cap portion 52 that is attached to container body 51. Protrusion 54 protrudes from the upper surface of cap body 53. By cutting any part of protrusion 54 and applying pressure (holding) to container 2, the thread locking agent is ejected from the cut part.
[0039] In this embodiment, as shown by the cutting line E in FIG. 7(a), the protrusion 54 is cut near the base. FIG. 7(b) is a diagram showing the container 2 in a state where the protrusion 54 has been cut off. The cut protrusion 54 is shown as a protrusion remaining part 54a. FIG. 7(c) is a diagram showing a state where the cap part 52 has been removed from the container body 51. As shown in FIG. 7(c), the container body 51 has a cylindrical attachment part 51a that opens toward the outside and to which the cap part 52 is attached. A screw shape is formed on the outer periphery of the attachment part 51a. Also, a screw shape is formed on the inner surface of the cap body 53. This allows the cap part 52 to be removed from the container body 51 by rotating it relative to the container body 51 (see arrow J). Also, by rotating it in the opposite direction, the container body 51 can be screwed into the cap part 52 and attached.
[0040] The cap part 52 removed from the container body 51 is placed in the arrangement part 20 of the screw locking jig 1, as shown in Fig. 8(a). The cap part 52 is placed in the arrangement part 20 so that the protruding part 54a faces or is inserted into the through hole 26. The outer surface of the cap body 53 and the inner surface of the arrangement part 20 are bonded with an adhesive (bonding part F in Fig. 8(a)).
[0041] Cap portion 52 fixed by adhesion is attached by screwing together with the screw locking jig 1 into attachment portion 51a of container body 51, as shown in Fig. 8(b). In this way, container 2 is attached to the screw locking jig 1, as shown in Fig. 3. If the thread locking agent inside container 2 runs out, the thread locking agent can be replenished by replacing container body 51 with another one.
[0042] (Application of thread locking agent) Fig. 9 is a diagram showing an example of the work of applying a thread locking agent to the threaded portion 61 of the bolt 60. As shown in Fig. 9, a large number of bolts 60 are arranged inside a container 70 with the threaded portion 61 facing upward.
[0043] The container 2 to which the thread locking jig 1 is attached is grasped, and the thread locking jig 1 is placed over the bolt 60 so that the threaded portion 61 is inserted into the screw insertion portion 30 (see FIG. 4A). Then, by applying pressure to the container 2, the thread locking agent is discharged from the protrusion remaining portion 54a, flows through the through hole 26 in the wall portion 22 into the spaces S1 and S2, and is discharged through the through hole 34 and from the opening 34a toward the threaded portion 61. The thread locking agent discharged from the opening 34a spreads in the gap G between the threaded portion 61 and the inner side surface 31c of the tubular portion 31 due to the discharge pressure, and is applied to the surface of the threaded portion 61.
[0044] In this way, the thread locking agent can be applied to the surface of the threaded portion 61 of the bolt 60 simply by placing the thread locking jig 1 on the bolt 60 and applying pressure to the container 2.
[0045] Also, as shown in FIG. 9, the thread locking agent can be applied to a large number of bolts 60 arranged in a row by simply covering the bolts 60 in sequence with the thread locking jig 1 and discharging the agent.
[0046] (Features, etc.) (1) The screw locking jig 1 of this embodiment includes a placement section 20, a screw insertion section 30 (an example of a first recess), a liquid flow path 40, and a plurality of openings 34a (an example of a first opening). A cap section 52 (an example of an outlet section) of a container 2 containing a screw locking agent (an example of a liquid for screw locking) is placed in the placement section 20. A threaded section 61 of a bolt 60 is inserted into the screw insertion section 30 from its tip 61a. The liquid flow path 40 is formed from the placement section 20 to the periphery of the screw insertion section 30. The plurality of openings 34a are formed on an inner surface 31c of the screw insertion section 30, and are connected to the liquid flow path 40.
[0047] As a result, when an operator pushes out the thread locking agent from the container 2, the thread locking agent coming out of the cap portion 52 arranged in the arrangement portion 20 passes through the liquid flow path 40 and is discharged from the multiple openings 34a toward the threaded portion 61 of the bolt 60 inserted into the screw insertion portion 30. The discharged thread locking agent spreads and is applied around the threaded portion 61 due to the discharge pressure.
[0048] Therefore, as shown in Figure 10, there is no need for the worker to push the liquid out of the container 2000 while rotating around the bolt 1000 to apply the liquid to the threaded portion 1100 of the bolt 1000, and the thread locking liquid can be applied around the threaded portion in a short amount of time.
[0049] In addition, since liquid is ejected from the opening 34a while the threaded portion 61 of the bolt 60 is inserted into the screw insertion portion 30, application can be performed in a stable state with reduced unevenness, and variation in application between the bolts 60 can be reduced.
[0050] (2) In the screw locking jig 1 of the present embodiment, the arrangement portion 20 is formed in a concave shape in which the cap portion 52 is disposed, and has an opening 26a (an example of a second opening) formed in a concave surface 22a (an example of a bottom surface) and connected to the liquid flow path 40. The surface 22a of the arrangement portion 20 is disposed opposite a surface 32a (an example of a bottom surface) of the screw insertion portion 30.
[0051] As a result, the thread locking agent discharged from the cap portion 52 is applied to the threaded portion through the opening 26a, the liquid flow path 40, and the opening 34a.
[0052] (3) In the screw locking jig 1 of the present embodiment, a plurality of openings 34a are formed at equal intervals along the circumferential direction of the screw insertion portion 30.
[0053] This allows the thread locking agent to be applied evenly around the entire circumference of the threaded portion 61 in a short period of time.
[0054] (4) The screw locking jig 1 of the present embodiment includes an outer member 11 (an example of a first member) and an inner member 12 (an example of a second member). The outer member 11 includes a placement portion 20. The inner member 12 includes a screw insertion portion 30 and an opening 34a. A liquid flow path 40 is formed between the outer member 11 and the inner member 12.
[0055] As a result, the screw locking jig 1 can be constructed by combining the outer member 11 and the inner member 12. Even if the screw locking agent becomes clogged, the outer member 11 and the inner member 12 can be disassembled to easily clean them.
[0056] (5) In the screw lock jig 1 of this embodiment, the outer member 11 has a cylindrical portion 21 (an example of a first cylindrical portion), a wall portion 22, and an inner member insertion portion 23 (an example of a second recess). The cylindrical portion 21 has an end 21a (an example of a first end) and an end 21b (an example of a second end). The wall portion 22 is disposed inside the cylindrical portion 21, and a through hole 26 (an example of a first through hole) is formed therein. The inner member insertion portion 23 is formed by a portion 212 (an example of a first portion) of the cylindrical portion 21 from the wall portion 22 to the end 21b, and the wall portion 22. The arrangement portion 20 is formed by a portion 211 (an example of a second portion) of the cylindrical portion 21 from the wall portion 22 to the end 21a, and the wall portion 22. The inner member 12 has a cylindrical portion 31 (an example of a second cylindrical portion), a cover portion 32, and a through hole 34 (an example of a second through hole). The cylindrical portion 31 has an end 31a (an example of a third end) and an end 31b (an example of a fourth end). The lid portion 32 is disposed so as to close the end 31a. The through hole 34 is formed in the cylindrical portion 31 and includes an opening 34a. The screw insertion portion 30 is formed by the cylindrical portion 31 and the lid portion 32. The inner member 12 is inserted into the inner member insertion portion 23 so that the lid portion 32 faces the wall portion 22 with a predetermined gap therebetween, and the cylindrical portion 31 faces the cylindrical portion 21 with a predetermined gap therebetween. The liquid flow path 40 includes a space S1 between the lid portion 32 and the wall portion 22, and a space S2 between the cylindrical portion 21 and the cylindrical portion 31.
[0057] As a result, by inserting the inner member 12 into the inner member insertion portion 23 of the outer member 11, the screw lock jig 1 can be constructed.
[0058] (6) In the screw locking jig 1 of this embodiment, the outer member 11 further has an outer protrusion 25 (an example of a first outer protrusion). The outer protrusion 25 is disposed around the entire circumferential circumference at the end 21b of the tubular portion 21 and protrudes outward. The inner member 12 further has an outer protrusion 33 (an example of a second outer protrusion). The outer protrusion 33 is disposed around the entire circumferential circumference at the end 31b of the tubular portion 31 and protrudes outward. The outer protrusion 25 and the outer protrusion 33 are bonded together.
[0059] This allows a seal to be formed between the outer member 11 and the inner member 12.
[0060] (7) In the screw locking jig 1 of the present embodiment, the outer member 11 further has an inner protrusion 24 (an example of a first inner protrusion). The inner protrusion 24 is disposed around the entire circumferential direction at the end 21b of the cylindrical portion 21 and protrudes inward. In the direction along the cylindrical portion 21, the position of an edge 24e of the inner protrusion 24 on the wall portion 22 side coincides with the position of an edge 34e of the through hole 34 on the end 31b side.
[0061] This allows the liquid to be ejected from the through-hole 34 disposed at the end of the liquid flow path 40.
[0062] (Other embodiments) Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the gist of the invention.
[0063] (A) In the above embodiment, it has been described that three or four through holes 34 are provided at equal intervals in the circumferential direction, but the number is not limited to this, and may be two, or five or more.
[0064] In the above embodiment, the multiple through holes 34 are provided at the same position from the end 31a in the direction along the central axis A, but they do not have to be at the same position.
[0065] In the above embodiment, the multiple through holes 34 are arranged so that the edge 34e on the end 31b side coincides with the edge 24e on the end 21a side of the inner protrusion 24, but in the direction along the central axis A, the edge 34e may be arranged closer to the ends 31a, 21a than the edge 24e.
[0066] In the above embodiment, the through holes 34 are provided in only one row in the direction along the central axis A, but they may be provided in multiple rows.
[0067] In the above embodiment, the through holes 34 are of the same size, but they may be of different sizes.
[0068] In short, the positions, sizes and number of the multiple through holes 34 may be appropriately set so that the thread locking agent can be appropriately applied to the bolt.
[0069] (B) In the above embodiment, the screw locking jig 1 is formed from two members, the outer member 11 and the inner member 12, but this is not limited to two and may be formed from one member or three or more members.
[0070] (C) In the above embodiment, the outer member 11 and the inner member 12 are bonded at both the bonded portion D1 and the bonded portion D2, but they may be bonded at only one of them.
[0071] (D) In the above embodiment, the outer member 11 and the inner member 12 are bonded with an adhesive to ensure sealing against the thread locking agent, but this is not the only option. For example, a seal such as an O-ring may be disposed between the outer protrusion 25 of the outer member 11 and the outer protrusion 33 of the inner member 12 to ensure sealing.
[0072] (E) In the above embodiment, the protrusion remainder 54a is inserted into the through hole 26, but it does not have to be inserted. Even if the protrusion remainder 54a is not inserted into the through hole 26, the thread locking agent discharged from the protrusion remainder 54a can flow into the through hole 26 as long as the inner surfaces of the cap portion 52 and the placement portion 20 are sealed with an adhesive. [Industrial Applicability]
[0073] The thread locking jig of the present disclosure has the effect of reducing variation and improving work efficiency, and is useful when applying a thread locking agent to a large number of bolts. [Explanation of symbols]
