In each drawing, some members may be omitted in order to clarify the drawing. Here, in the following description, in order to clarify the description, description will be made using an orthogonal coordinate (xyz) system.

  As shown in FIGS. 1 and 2, the multi-axis temporary fastening tool 1 of the present embodiment includes a plurality of (four in the illustrated example) socket 2, a base portion 3, a gear mechanism 4, an input portion 5, and a rotation suppression mechanism 6. And is used to simultaneously temporarily tighten bolts 8 as screwing members into screw holes 7a as a plurality of screwed parts of the work 7.

  In addition, although the multi-axis temporary fastening tool 1 of this Embodiment is provided with the four sockets 2, if it is plurality, the number will not be limited. In this embodiment, the screwed portion is the screw hole 7a and the screwing member is the bolt 8. The screwed portion is a bolt (for example, a stud bolt), and the screwing member is a nut. There may be.

  A bolt head 8 a of the bolt 8 is inserted into the socket 2 and engaged. As shown in FIG. 3, the socket 2 of the present embodiment includes a main body portion 2a and an engaged portion 2b. For example, the main body 2a is made of resin (however, the material is not limited) in order to suppress damage to the work 7 even if it contacts the work 7 and to reduce the weight of the multi-axis temporary fastening tool 1. It is. And the main-body part 2a makes columnar shape (for example, cylindrical shape) a basic form, and is provided with the to-be-inserted part 2c.

  The inserted portion 2c is, for example, a concave portion formed on the z-axis-side surface of the socket 2, and includes a tapered portion 2d and an accommodating portion 2e as shown in FIG. The taper portion 2d extends in the z-axis + direction from the z-axis-side surface of the main body portion 2a, decreases in diameter toward the z-axis + side, and continues to the housing portion 2e. As shown in FIG. 5, the accommodating portion 2e is a circular hole having a diameter L2 larger than the diagonal distance L1 of the bolt head 8a, and extends in the z-axis + direction.

  Here, the depth D1 (FIG. 4) of the inserted portion 2c is such that, for example, the surface of the main body 2a on the z-axis side protrudes from the bolt head 8a in a state where the bolt head 8a is inserted into the inserted portion 2c. It is good to set so that the surface on the z axis | shaft + side of the bolt head 8a may contact the flange part 8b to perform, and the bottom face of the accommodating part 2e.

  As shown in FIGS. 4 and 5, the engaged portion 2 b is a protruding portion that protrudes in the radial direction from the peripheral surface of the accommodating portion 2 e. The engaged portion 2b of the present embodiment is made of a substantially cylindrical metal pin, and is fixed to the main body portion 2a so as to extend in the z-axis direction. The engaged portion 2b is arranged so that the bolt head 8a can be inserted into the inserted portion 2c and the corner portion of the bolt head 8a is hooked (engaged) when the socket 2 is rotated. ing. For example, the engaged portions 2b are arranged at two locations so as to face each other. Incidentally, although the detailed function will be described later, the z-axis-side end portion of the engaged portion 2b is preferably tapered so as to become narrower toward the z-axis-side.

  Such a socket 2 is supported by a base 3 as shown in FIGS. 1 and 6. For example, a bar screw 9 is screwed into the surface on the z axis + side of the socket 2. The bar screw 9 extends substantially in the z-axis direction, and is passed through a through hole 3a formed in the base 3 via a bearing (not shown). At this time, the inner diameter of the bearing is larger than the outer diameter of the bar screw 9 in order to allow the socket 2 to swing.

  A first nut 10 is screwed into the z-axis-side portion of the bar screw 9 with the base 3 interposed therebetween. The first nut 10 is disposed so as to substantially contact the surface of the socket 2 on the z axis + side.

  On the other hand, a second nut 11 is screwed into a portion on the z axis + side across the base 3 of the bar screw 9. The second nut 11 is arranged at a predetermined interval from the first nut 10 in the z-axis direction. For example, as shown in the right diagram of FIG. 7, in a state where the socket 2 is moved in the z axis − direction most with respect to the base 3 and the second nut 11 is in contact with the z axis + side surface of the base 3. The second nut 11 is arranged so that a gap G1 corresponding to about two pitches of the bolt 8 is secured between the z-axis + side surface of the first nut 10 and the z-axis-side surface of the base 3. Has been placed. As a result, as shown in FIGS. 6 and 7, the socket 2 is supported by the base 3 so as to be able to swing (that is, the socket 2 can tilt) and to be movable in the z-axis direction.

  The base 3 is a plate member. As will be described in detail later, the base 3 has a plurality of screw holes 7a in which the bolts 8 are temporarily tightened simultaneously with the multi-axis temporary tightening tool 1 in the work 7 in a state where the bolts 8 are temporarily tightened with the socket 2 by a predetermined amount. It is made into the shape which contacts the inner wall 7b surrounding at least one part of area | region A1 containing.

  The base 3 of the present embodiment is made of resin (however, in order to reduce damage to the inner wall 7b even if it contacts the inner wall 7b of the workpiece 7 and to reduce the weight of the multi-axis temporary fastening tool 1) Is not limited). The base 3 has a substantially rectangular shape when viewed from the z-axis direction (however, any shape that can contact the inner wall 7 b) is inclined so that the side surface corresponds to the inner wall 7 b of the workpiece 7.

  The gear mechanism 4 transmits the driving force input from the input unit 5 to each socket 2. As shown in FIGS. 2 and 8, the gear mechanism 4 according to the present embodiment includes an input gear 4a, an output gear 4b, and an intermediate gear 4c.

  For example, as shown in FIG. 9, the input gear 4 a is a spur gear made of resin (however, the material is not limited), and includes a through hole 4 d that penetrates in the center in the z-axis direction. A shaft portion 12 a of a bolt 12 screwed into a screw hole 3 b formed in the approximate center of the surface on the z axis + side of the base portion 3 is passed through the through hole 4 d through a bearing 13. Thereby, the input gear 4a can rotate around the shaft portion 12a extending in the z-axis direction of the bolt 12.

  Incidentally, in the present embodiment, the nut 14 screwed into the shaft portion 12a of the bolt 12 is pressed against the base portion 3, and the bolt 12 is fixed by a double nut structure of the nut 14 and the screw hole 3b of the base portion 3. In the bolt 12, loosening from the screw hole 3b of the base 3 is suppressed.

  The output gear 4b is, for example, a spur gear made of resin (however, the material is not limited), and includes a through hole (not shown) that penetrates in the center in the z-axis direction. The z-axis + side end of the bar screw 9 screwed into the socket 2 is passed through a through hole of the output gear 4b through a bearing (not shown), and the output gear 4b is passed through the second nut 11. A third nut 15 is screwed into the bar screw 9 so as to be sandwiched between. As a result, the output gear 4 b can rotate around the bar screw 9.

  The intermediate gear 4c is, for example, a spur gear made of resin (however, the material is not limited), and includes a through hole 4e penetrating in the center in the substantially z-axis direction. The intermediate gear 4c is meshed with the input gear 4a and the output gear 4b. A rotation shaft 4f protruding from the base portion 3 in the z-axis + direction is passed through the through hole 4e of the intermediate gear 4c. Thus, the intermediate gear 4c can transmit the driving force of the input gear 4a to the output gear 4b while rotating about the rotation shaft 4f.

  Here, as shown in FIG. 6, when the socket 2, and hence the bar screw 9, tilts, the output gear 4 b swings in conjunction with the bar screw 9. At this time, if the position of the intermediate gear 4c is fixed, the swing of the output gear 4b is hindered. Therefore, although detailed operation will be described later, as shown in FIG. 8, the diameter of the through hole 4e of the intermediate gear 4c is made larger than the diameter of the rotary shaft 4f so as not to hinder the swinging of the output gear 4b. 4c can move substantially parallel to the xy plane. That is, the gear mechanism 4 has a play that allows the base 2 to swing the socket 2.

  Further, when the socket 2 moves to the z-axis + side most with respect to the base 3, the output gear 4b also moves to the x-axis + side, but at this time, the intermediate position is not released so that the engagement with the output gear 4b is not released. The thickness of the gear 4c is set.

  The input unit 5 is operated by an operator to input driving force to the input gear 4a. As shown in FIG. 9, the input unit 5 of the present embodiment is connected to the input gear 4 a via a bolt 16. Specifically, the bolt 16 passed through the through hole 4g formed in the input gear 4a is screwed into a screw hole formed in the z-axis-side surface of the input unit 5 and integrated.

  The input unit 5 has, for example, a pillar shape (in the illustrated example, a cylindrical shape, but may be a polygonal shape) as a basic form, and includes a through hole 5a and a knob portion 5b. Such an input unit 5 is preferably made of urethane so that the operator's hand is familiar and the weight of the multi-axis temporary fastening tool 1 can be reduced.

  The through-hole 5a extends in the z-axis direction at the center of the input portion 5, is disposed on the z-axis + side with respect to the small-diameter portion 5c on the z-axis side and the small-diameter portion 5c, and is formed on the small-diameter portion 5c. On the other hand, a large diameter portion 5d having a large diameter is provided. The shaft portion 12a of the bolt 12 is passed through the small diameter portion 5c of the through hole 5a, and the bolt head 12b of the bolt 12 is accommodated in the large diameter portion 5d. At this time, as shown in FIG. 10, the multi-axis temporary fastening tool 1 is mounted on the mounting table 17, and the input unit 5 and the input gear 4 a are arranged on the z axis + side most with respect to the base 3. A predetermined gap G2 is secured between the z-axis-side surface of the bolt head 12b of the bolt 12 and the step portion between the small diameter portion 5c and the large diameter portion 5d of the through hole 5a. When the worker lifts the multi-axis temporary fastening tool 1 via the input unit 5, as shown in FIG. 1, the z-axis-side surface of the bolt head 12b of the bolt 12 is the small diameter portion 5c of the through hole 5a. The input unit 5 and the input gear 4a move in the z-axis + direction until they come into contact with the stepped portion between the large diameter portion 5d and the large diameter portion 5d. Thus, the input unit 5 and the input gear 4a are movable in the z-axis direction.

  As shown in FIG. 11, the knob 5 b is a groove formed on the outer peripheral surface of the input unit 5 at a predetermined interval in the circumferential direction of the input unit 5. The knob portion 5b extends in the z-axis direction, and the depth and width are set so that the operator's finger can be satisfactorily hooked.

  The rotation suppression mechanism 6 locks the gear mechanism 4 when the multi-axis temporary fastening tool 1 is conveyed. As shown in FIG. 1, the rotation suppression mechanism 6 of the present embodiment includes a claw portion 6a and a support portion 6b. The claw portion 6 a is disposed on the gear mechanism 4 side with respect to the base portion 3. For example, as shown in FIG. 12, the claw portion 6a has an isosceles triangle (provided that the shape can be meshed with the input gear 4a) as viewed from the z-axis direction, and the support portion 6b. It is connected to the base 3 via

  In such a claw portion 6a, the input portion 5 and the input gear 4a are moved to the z axis + side with respect to the base portion 3, that is, the z axis − side surface of the bolt head 12b of the bolt 12 is a through hole. 5a is engaged with the input gear 4a while being in contact with the stepped portion between the small diameter portion 5c and the large diameter portion 5d, and the input portion 5 and the input gear 4a are disposed closest to the z-axis with respect to the base portion 3. Thus, it is not meshed with the input gear 4a. Therefore, the above-mentioned gap G2 is at least larger than the thickness of the input gear 4a.

  However, as shown in FIG. 13, the claw portion 6 a may have a triangular shape in which a corner portion is arranged on the z axis − side when viewed from the direction orthogonal to the z axis. In this case, the corner portion of the claw portion 6a is engaged with the input gear 4a on the z axis + side of the input gear 4a.

FIG. 21 is a bottom view schematically showing the positional relationship between the engaged portion of the socket and the bolt head of the bolt when the bolt is temporarily tightened with the socket of the multi-axis temporary tightening tool of the present embodiment. FIG. 22 is a front view schematically showing a state immediately after the side surface of the base portion of the multi-axis temporary fastening tool of the present embodiment contacts the inner wall of the workpiece. FIG. 23 is a front view schematically showing a state in which the socket has moved most to the z-axis side with respect to the base after the side surface of the base of the multi-axis temporary fastening tool of the present embodiment has contacted the inner wall of the workpiece. . FIG. 24 is a front view schematically showing a state in which the bolts are temporarily tightened using the multi-axis temporary tightening tool of the present embodiment.

  Here, as shown in FIG. 1, the workpiece 7 according to the present embodiment surrounds a region A <b> 1 including a plurality of screw holes 7 a into which bolts 8 are simultaneously screwed using the multi-axis temporary fastening tool 1 in the workpiece 7. An inner wall 7b is provided. The inner wall 7b is an inclined surface that is inclined so as to approach the region A1 side toward the z-axis-side.

  First, as shown in FIG. 1, the shaft 8c of the bolt 8 is inserted into the bolt insertion hole 7c communicated with the screw hole 7a in the workpiece 7, and the bolt 8 is set up. Then, the operator lifts the multi-axis temporary fastening tool 1 from the state where the multi-axis temporary fastening tool 1 is placed on the mounting table 17 via the input unit 5, and the rotation axis AX 1 of each bolt 8 and the socket 2 The multi-axis temporary fastening tool 1 is moved to the z axis + side with respect to the region A1 so that the rotation axis AX2 is arranged substantially coaxially.

  Next, as shown in FIG. 14, the multi-axis temporary fastening tool 1 is moved in the z-axis direction to try to insert the bolt head 8 a of the bolt 8 into the inserted portion 2 c of the socket 2. The gear 4a is moved in the z-axis direction. Thus, until the socket 2 contacts the bolt 8, the input portion 5 and the input gear 4a are arranged on the z axis + side with respect to the base portion 3, and the claw portion 6a of the rotation suppression mechanism 6 is engaged with the input gear 4a. Thus, the gear mechanism 4 is locked. Therefore, relative rotation between the base 3 and the input unit 5 is suppressed, and the multi-axis temporary fastening tool 1 is easy to use. On the other hand, when the input unit 5 and the input gear 4a are pushed in the z-axis direction after the socket 2 contacts the bolt 8, the input unit 5 and the input gear 4a are arranged on the z-axis side most with respect to the base unit 3. Thus, the meshing state between the claw portion 6a of the rotation suppression mechanism 6 and the input gear 4a is released. As a result, the lock of the gear mechanism 4 is released, the input gear 4 a can rotate, and the driving force can be transmitted to the socket 2 via the gear mechanism 4.

  At this time, as shown in FIG. 15, the bolt head 8 a of the bolt 8 is guided to the accommodating portion 2 e along the inclination of the tapered portion 2 d of the inserted portion 2 c in the socket 2. 16, when the engaged portion 2b of the socket 2 is disposed between the corners of the bolt head 8a of the bolt 8, the engaged portion 2b of the socket 2 Since the insertion of the socket 2 into the accommodating portion 2e of the bolt head 8a of the bolt 8 is not hindered, when the operator further pushes the socket 2 in the z-axis direction via the input portion 5 or the base portion 3, the upper diagram of FIG. And the bolt head 8a of the volt | bolt 8 is accommodated in the accommodating part 2e of the socket 2, as shown in FIG. Here, since the tip of the engaged portion 2b of the socket 2 is tapered, the bolt head 8a of the bolt 8 can be smoothly inserted into the accommodating portion 2e of the socket 2.

  On the other hand, as shown in FIG. 17, when the bolt head 8a of the bolt 8 interferes with the engaged portion 2b of the socket 2, the tip of the engaged portion 2b in the socket 2 is tapered as shown in FIG. Therefore, when the socket 2 is pushed in the z-axis direction, as shown in FIG. 19, at least one of the bolt 8 and the socket 2 is rotated. As a result, the engaged portion 2b of the socket 2 is It arrange | positions between the corner | angular part of the bolt head 8a. When the operator further pushes the socket 2 in the z-axis direction via the input unit 5 and the base 3, the bolt head 8a of the bolt 8 accommodates the socket 2 as shown in the upper diagram of FIG. It is accommodated in the part 2e.

  At this time, when the bolt head 8 a of the bolt 8 is inserted into the inserted portion 2 c of the socket 2, the side surface of the base 3 is not yet in contact with the inner wall 7 b of the workpiece 7. Then, in a state where the socket 2 is moved most to the z axis + side with respect to the base 3, the z axis + side surface of the bolt head 8 a in the bolt 8 is the accommodating portion in the socket 2 as shown in the upper diagram of FIG. The surface of the bolt 8 is in surface contact with the surface on the z axis + side of the flange portion 8b of the bolt 8 and is in surface contact with the surface on the z axis − side of the main body portion 2a of the socket 2. Accordingly, as shown in FIG. 20, the rotation axis AX1 of the bolt 8, the rotation axis AX2 of the socket 2 of the multi-axis temporary fastening tool 1, and the central axis AX3 of the screw hole 7a of the workpiece are substantially on the same axis. The rotation axes AX1 and AX2 and the center axis AX3 are substantially orthogonal to the xz plane.

  Further, the portion on the z axis + side (that is, the bar screw 9) sandwiching the socket 2 is passed through the through hole 3a of the base portion 3 through a bearing, and the portion on the z axis − side (that is, the bolt is sandwiched between the socket 2). Since 8) is inserted into the bolt insertion hole 7c of the workpiece 7, the socket 2 is supported at both ends in the z-axis direction, and the tilt of the socket 2 can be suppressed.

  When the operator rotates the input unit 5, the driving force of the input unit 5 is transmitted to the socket 2 via the input gear 4a, the intermediate gear 4c, and the output gear 4b, and the socket 2 rotates. Then, as shown in FIG. 21, the engaged portion 2 b of the socket 2 is engaged with the bolt head 8 a of the bolt 8, and the bolt 8 rotates and is screwed into the screw hole 7 a of the workpiece 7.

  When the operator rotates the input unit 5, the bolt 8 is further screwed into the screw hole 7 a of the work 7. Accordingly, the socket 2 moves together with the bolt 8 in the z-axis direction. At this time, the base 3 is in a state of being placed on the z-axis + side surface of the first nut 10, and the base 3 is moved in the z-axis − direction as the socket 2 moves in the z-axis − direction. The side surface of the base 3 comes into contact with the inner wall 7b of the work 7 as shown in FIG. Thereby, the movement to the z-axis negative direction of the base 3 is suppressed. At this time, the operator can recognize that the completion of the temporary tightening of the bolt 8 is approaching soon because the side surface of the base 3 is in contact with the inner wall 7 b of the workpiece 7. Therefore, the side surface of the base portion 3 functions as a movement suppressing portion that suppresses movement of the base portion 3 in the z-axis direction.

  Here, when the side surface of the base portion 3 comes into contact with the inner wall 7b of the workpiece 7, the moment when the operator rotates the input portion 5 can be received by the inner wall 7b of the workpiece 7, and the input gear 4a, the output gear 4b, The gear ratio can be increased. Therefore, when the bolt 8 is temporarily tightened, the rotational speed of the input unit 5 can be reduced.

  When the operator rotates the input unit 5, the bolt 8 is further screwed into the screw hole 7 a of the work 7. Accordingly, the socket 2 moves together with the bolt 8 in the z-axis direction, and the z-axis-side surface of the second nut 11 contacts the z-axis + side surface of the base 3 as shown in FIG. . Thereby, the movement of the socket 2 in the z-axis direction is suppressed.

  When the operator rotates the input unit 5, the bolt 8 is further screwed into the screw hole 7 a of the work 7. Accordingly, the bolt 8 moves in the z-axis direction with respect to the socket 2, and the engagement between the bolt head 8a of the bolt 8 and the engaged portion 2b of the socket 2 is released. Thereby, the temporary fastening to the screw hole 7a of the workpiece | work 7 of the volt | bolt 8 is completed. Thus, when the engagement between the bolt head 8a of the bolt 8 and the engaged portion 2b of the socket 2 is released, the load for rotating the input portion 5 is reduced. It can be recognized that the temporary fastening to the hole 7a has been completed.

  Here, as described above, the gap G1 between the first nut 10 and the base 3 is, for example, about two pitches of the bolt 8, so that the screw thread between the bolt 8 and the screw hole 7a of the workpiece 7 is reduced. Even if the bolt 8 is not immediately screwed into the screw hole 7a of the workpiece 7, the bolt 8 can be reliably screwed into the screw hole 7a of the workpiece.

  Next, the flow of temporarily tightening the bolt 8 inserted into the bolt insertion hole 7c of the workpiece 7 in a tilted state using the multi-axis temporary tightening tool 1 of the present embodiment will be described.

  FIG. 25 is a front view schematically showing a state in which a bolt inserted in a tilted state into a bolt insertion hole of a workpiece is temporarily tightened with the multi-axis temporary tightening tool of the present embodiment. FIG. 26 is a front view schematically showing a state in which the socket in the multi-axis temporary fastening tool of the present embodiment is in contact with the bolt. FIG. 27 is a diagram schematically illustrating how the intermediate gear escapes from between the input gear and the output gear so as to allow the socket to tilt. FIG. 28 is a diagram schematically showing a state in which the bolt head of the bolt is inserted into the socket of the multi-axis temporary tightening tool of the present embodiment. The upper diagram shows a front view and the lower diagram shows a bottom view. ing. FIG. 29 is a front view schematically showing a bolt whose inclination is corrected in the socket of the multi-axis temporary fastening tool of the present embodiment. FIG. 30 is a diagram schematically illustrating a state in which the escaped intermediate gear is drawn between the input gear and the output gear.

  As shown in FIG. 25, when the shaft portion 8c of the bolt 8 is tilted and inserted into the bolt insertion hole 7c of the workpiece 7, when the multi-axis temporary fastening tool 1 is moved in the z-axis direction, it is shown in FIG. As described above, the bolt head 8 a of the bolt 8 is inserted into the inserted portion 2 c of the socket 2 in a tilted state. At this time, since the diameter of the through hole 4e of the intermediate gear 4c is larger than the diameter of the rotating shaft 4f, the bolt head 8a of the bolt 8 comes into contact with the tapered portion 2d of the insertion hole 2c in the socket 2 so that the socket 2 tilts. When the output gear 4b pushes in the intermediate gear 4c, the intermediate gear 4c escapes from between the input gear 4a and the output gear 4b as shown in FIG. Thereby, tilting of the socket 2 is permitted.

  When the operator moves the multi-axis temporary tightening tool 1 in the z-axis-direction via the base 3 or the input unit 5, the bolt head 8a of the bolt 8 is connected to the inserted portion 2c of the socket 2 as shown in FIG. It guide | induces to the accommodating part 2e along the taper part 2d, and as shown in FIG. 29, the inclination of the volt | bolt 8 is corrected.

  When the worker moves the multi-axis temporary fastening tool 1 in the z-axis-direction via the base 3 or the input unit 5, the engaged portion 2 b of the socket 2 becomes the corner portion and the corner portion of the bolt head 8 a of the bolt 8. The surface of the bolt 8 on the z axis + side of the bolt head 8 is in surface contact with the bottom surface of the housing portion 2e of the socket 2 and the surface of the flange 8b of the bolt 8 on the z axis + side is the socket. 2 is in surface contact with the z-axis-side surface of the body 2a.

  When the operator rotates the input unit 5, as shown in FIG. 30, the intermediate gear 4c is drawn between the input gear 4a and the output gear 4b as the input unit 5 rotates, and the input gear 4a and the output gear 4b. Thereby, the driving force of the input part 5 is transmitted to the socket 2, the socket 2 rotates, and the bolt 8 is temporarily tightened. The subsequent flow until the temporary tightening of the bolt 8 is completed is the same as that shown in FIGS.

  Next, when the multi-axis temporary fastening tool 1 of the present embodiment is arranged on the z-axis + side with respect to the area A1, the rotation axis AX2 of the socket 2 and the rotation axis AX1 of the bolt 8 are displaced from the bolt. The flow of temporarily tightening 8 will be described.

  FIG. 31 is a front view schematically showing a state in which the rotation axis of the socket and the rotation axis of the bolt are displaced when the multi-axis temporary fastening tool of the present embodiment is arranged on the z axis + side with respect to the bolt. It is. FIG. 32 is a front view schematically showing a state in which the socket of the multi-axis temporary tightening tool of the present embodiment is in contact with being inclined with respect to the bolt. FIG. 33 is a front view schematically showing a state in which the side surface of the base portion of the multi-axis temporary fastening tool of the present embodiment contacts the inner wall of the workpiece and the base portion moves to the x-axis side.

  As shown in FIG. 31, in the state where the rotation axis AX2 of the socket 2 of the multi-axis temporary tightening tool 1 is displaced from the rotation axis AX1 of the bolt 8, the multi-axis temporary tightening tool 1 is z-axis + When the multi-axis temporary fastening tool 1 is moved in the z-axis direction, a part of the bolt head 8a of the bolt 8 comes into contact with the socket 2 as shown in FIG. It will be tilted. At this time, the socket 2 tilts and the intermediate gear 4c escapes from between the input gear 4a and the output gear 4b.

  When the operator moves the multi-axis temporary fastening tool 1 in the z-axis direction via the base 3 or the input unit 5, the rotation axis AX <b> 2 of the socket 2 in the base 3 is shifted from the rotation axis AX <b> 1 of the bolt 8. As shown in FIG. 33, the side surface of the side (in the present embodiment, the x-axis + side) contacts the inner wall 7b of the workpiece 7, and the side of the base 3, and thus the multi-axis temporary fixing tool 1, is shifted. Is pushed in the opposite direction (x-axis direction in this embodiment).

  At the same time, the bolt head 8a of the bolt 8 is guided to the accommodating portion 2e along the tapered portion 2d of the inserted portion 2c of the socket 2, and the rotation axis AX2 of the socket 2 is arranged substantially coaxially with the rotation axis AX1 of the bolt 8. Is done.

  When the worker moves the multi-axis temporary fastening tool 1 in the z-axis-direction via the base 3 or the input unit 5, the engaged portion 2 b of the socket 2 becomes the corner portion and the corner portion of the bolt head 8 a of the bolt 8. The surface of the bolt 8 on the z axis + side of the bolt head 8 is in surface contact with the bottom surface of the housing portion 2e of the socket 2 and the surface of the flange 8b of the bolt 8 on the z axis + side is the socket. 2 is in surface contact with the z-axis-side surface of the body 2a.

  When the operator rotates the input unit 5, the intermediate gear 4 c is pulled between the input gear 4 a and the output gear 4 b as the input unit 5 rotates, and meshes with the input gear 4 a and the output gear 4 b. Thereby, the driving force of the input part 5 is transmitted to the socket 2, the socket 2 rotates, and the bolt 8 is temporarily tightened. The subsequent flow until the temporary tightening of the bolt 8 is completed is the same as that shown in FIGS.

  In such a multi-axis temporary fastening tool 1, when the worker transports the multi-axis temporary fastening tool 1, the gear mechanism 4 is locked and relative rotation between the base 3 and the input unit 5 is suppressed. The positioning when the bolt head 8a of the bolt 8 is inserted into the inserted portion 2c of the socket 2 is easy. Moreover, it is possible to carry the multi-axis temporary fastening tool 1, push the socket 2, and rotate the input unit 5 with one hand.

Further, since the socket 2 is configured to be able to swing, the rotation axis AX2 of the socket 2 is displaced with respect to the rotation axis AX1 of the bolt 8, or the shaft portion 8c of the bolt 8 is the bolt insertion hole 7c of the workpiece 7. Even if it is inserted inclining, the bolt 8 can be temporarily tightened well.
From the above, the multi-axis temporary fastening tool 1 of the present embodiment is easy to use.

  Furthermore, in the multi-axis temporary fastening tool 1 of the present embodiment, when the bolt 8 is temporarily tightened by a predetermined amount, the side surface of the base 3 comes into contact with the inner wall 7b of the workpiece 7, so that the operator can temporarily tighten the bolt 8. You can recognize that the completion of is approaching. In particular, in the multi-axis temporary fastening tool 1 of the present embodiment, the engagement between the engaged portion 2b of the socket 2 and the bolt head 8a of the bolt 8 is finally released. Therefore, the bolt 8 is not tightened too much.

  Moreover, since the socket 2, the base part 3, the gear mechanism 4, and the input part 5 are comprised with the lightweight member, the multi-axis temporary fastening tool 1 of this Embodiment is lightweight and convenient.

<Embodiment 2>

FIG. 44 is a plan view schematically showing the multi-axis temporary fastening tool of the present embodiment. FIG. 45 is a diagram schematically showing different claw portions of the rotation suppression mechanism in the multi-axis temporary fastening tool of the present embodiment. In FIG. 44, the intermediate gear is omitted for the sake of clarity.

  As shown in FIGS. 42 to 44, the rotation suppression mechanism 41 of the present embodiment is in a state where the multi-axis temporary fastening tool 42 is lifted and the socket 2 is moved most in the z-axis direction with respect to the base 3. A claw portion 41a meshed with the output gear 4b is provided. The claw portion 41a is disposed on the gear mechanism 4 side with the base portion 3 interposed therebetween. The claw portion 41a has, for example, a substantially isosceles triangle (as long as it can be meshed with the output gear 4b) as viewed from the z-axis direction, and has a base portion via the support portion 41b. 3 is connected.

  As shown in FIGS. 47 and 48, the socket 61 of the present embodiment has a columnar shape (in the illustrated example, a cylindrical shape) as a basic form, and extends from the z-axis-side surface to the z-axis + side. An inserted portion 61a is provided. The socket 61 is made of, for example, urethane that can suppress damage to the workpiece 7 even if it contacts the workpiece 7 and can reduce the weight of the multi-axis temporary fastening tool. However, the socket 61 is only required to be formed of a material that can be deformed and satisfactorily engaged with the bolt head 8a of the bolt 8 as will be described later.

  The inserted portion 61a includes a tapered portion 61b and a housing portion 61c. The taper portion 61b extends in the z-axis + direction from the z-axis-side surface of the socket 61, decreases in diameter toward the z-axis + side, and continues to the housing portion 61c. The accommodating part 61c is a circular hole having a diameter L3 smaller than the diagonal distance L1 of the bolt head 8a of the bolt 8, and extends in the z-axis + direction.

  When the bolt 8 is temporarily tightened using such a socket 61, for example, as shown in FIG. 49, even if the socket 61 is inclined with respect to the bolt 8, the bolt head 8a of the bolt 8 is inserted into the socket 61. It is guided to the inserted portion 61a along the tapered portion 61b of the portion 61a. As a result, as shown in FIG. 50, the rotation axis AX1 of the bolt 8 and the rotation axis AX4 of the socket 61 are arranged on substantially the same axis.

  When the worker moves the multi-axis temporary fastening tool in the z-axis direction via the base 3 or the input unit 5, the socket 61 is compressed and the accommodating portion 61c is expanded. Further, when the worker moves the multi-axis temporary tightening tool in the z-axis direction via the base 3 or the input unit 5, the bolt head 8 a of the bolt 8 is placed in the housing 61 c of the socket 61 as shown in FIG. 51. Be contained. At this time, the accommodating portion 61c of the socket 61 is in close contact with the bolt head 8a while being deformed into a hexagonal shape when viewed from the z-axis direction so as to correspond to the bolt head 8a of the bolt 8. Accordingly, the bolt 8 can be temporarily tightened using the socket 61.

<Embodiment 7>
In the sixth embodiment, the socket 61 is used when the bolt 8 is temporarily tightened. However, as shown in FIG. 52, it can also be used when the nut 71 is temporarily tightened.

  When the nut 71 is temporarily tightened with the socket 61 in this manner, for example, if the tip of the rod screw 9 inserted into the socket 61 protrudes from the bottom surface of the housing portion 61c, the nut 71 can be easily positioned. Incidentally, the tip of the bar screw 9 has a smaller diameter than the screw hole of the nut 71. That is, the tip of the bar screw 9 can be inserted into the screw hole of the nut 71.

  53 to 56 are diagrams schematically showing a state in which a nut is inserted into the socket according to the present embodiment. The upper diagram shows a front view, and the lower diagram shows a bottom view.

  As shown in FIG. 53, when the rotation axis AX4 of the socket 61 is deviated from the rotation axis AX5 of the nut 71, the operator inserts the multi-axis temporary fastening tool through the base 3 or the input unit 5 in the z-axis direction. As shown in FIG. 54, the nut 71 moves along the tapered portion 61b of the insertion portion 61a of the socket 61, and the screw hole 71a of the nut 71 is guided to the tip 9a of the rod screw 9.

  When the operator moves the multi-axis temporary fastening tool in the z-axis direction via the base 3 or the input unit 5, as shown in FIG. 55, the socket 61 is compressed and the accommodating portion 61c is pushed open. Further, when the worker moves the multi-axis temporary tightening tool in the z-axis direction via the base 3 or the input unit 5, the screw hole 71a of the nut 71 is formed at the tip 9a of the bar screw 9 as shown in FIG. The nut 71 is accommodated in the accommodating portion 61 c of the socket 61. As a result, the nut 71 can be temporarily tightened using the socket 61.

  The present invention is not limited to the above-described embodiment, and can be changed as appropriate without departing from the spirit of the present invention.

  For example, the engaged portions 2b of the socket 2 according to the first embodiment are arranged at two places so as to face each other, but as shown in FIG. Alternatively, as shown in FIG. 58, the socket 2 may be arranged at six locations at substantially equal intervals in the circumferential direction. In short, if the engagement portion 2b can be engaged with the screwing member when the socket 2 is rotated without interfering with the insertion of the screwing member into the insertion portion 2c of the socket 2, the engagement becomes possible. The arrangement and shape of the part 2b are not limited. In FIGS. 57 and 58, the tapered portion and the accommodating portion of the inserted portion are shown in a simplified manner.

  For example, the configuration of the rotation suppression mechanism is not limited to the above, and for example, the gear mechanism 4 may be locked by inserting a pin into a fitting hole formed in the input gear or the like by an actuator or the like provided in the base. In short, any structure that can lock the gear mechanism 4 when the input unit is lifted and the multi-axis temporary fastening tool is conveyed may be used.

  For example, the configuration of the socket is not limited to the above, and a socket used in a general electric tool may be used.
