  The present invention relates to a tool storage device, and more particularly to a tool storage device including a tool pot to which a tool holder for holding a tool is attached and detached.

  2. Description of the Related Art Conventionally, a machine tool that cuts a workpiece is equipped with a tool storage device that can store a plurality of tools such as taps and drills attached to a spindle. As such a tool storage device, for example, a tool pot in which a tool holder for holding a tool is attached and detached, and the tool pot is rotatably supported, and along a predetermined path including a predetermined index position. There is known a tool storage device provided with a transfer means for transferring a tool pot (for example, see Patent Document 1). In this type of tool storage device, an endless chain is stretched between a pair of sprockets, and a plurality of tool pots are attached to the outer peripheral side of the chain via brackets. When one of the sprockets is rotationally driven by the motor, the plurality of tool pots are transferred along a predetermined path together with the chain. Furthermore, a desired tool moves to a predetermined index position by controlling the motor by the control device.

By the way, the tool pot provided in such a tool storage apparatus is provided with the main-body part formed in the bottomed cylindrical shape. A tool mounting hole is formed on the front side of the main body, and a holding mechanism for holding a pull stud provided at the rear end of the tool holder is provided on the side of the flange. As a tool pot provided with such a holding mechanism, for example, a steel pot provided with a coil spring so as to be retractable toward the inside of the tool mounting hole is known. When the tool holder is inserted into the tool insertion hole of the tool pot, the steel ball is pushed back to the pull stud of the tool holder. Thereafter, the steel ball settles on the neck portion that is narrowed in the radial direction of the pull stud, and engages with the head that expands in diameter. Such a holding mechanism can prevent the pull stud from coming off. Further, at the same time that the pull stud is held, the outer peripheral surface of the frustoconical shank provided on the rear end side of the tool holder comes into contact with the open end of the tool pot. Thereby, since the insertion distance of the tool holder is limited and positioned, the mounting of the tool holder in the tool pot is completed.

  Hereinafter, a tool magazine 1 according to an embodiment of the present invention will be described with reference to the drawings. A tool magazine 1 shown in FIG. 1 is a device for storing a tool 5 such as a tap or a drill mounted on a spindle of a machine tool (not shown) and transferring it along a circulation path including an index position. . The tool magazine 1 corresponds to the “tool storage device” of the present invention.

  First, the structure of the tool magazine 1 will be schematically described with reference to FIGS. FIG. 1 is a front view of the tool magazine 1, and FIG. 2 is a left side view of the tool magazine 1. As shown in FIGS. 1 and 2, the tool magazine 1 includes a magazine base 11 fixed to a main body (not shown) of a machine tool and a plurality of bottomed cylindrical shapes transferred along the outer periphery of the magazine base 11. The tool pot 10 is provided. A tool holder 60 that holds the tool 5 is detachably attached to the tool pot 10. The plurality of tool pots 10 are respectively attached to a transfer mechanism 12 disposed inside the magazine base 11.

  As shown in FIG. 1, the transfer mechanism 12 includes a pair of sprockets 13 and 14 rotatably disposed inside the magazine base 11, and an endless chain 16 spanned between the sprockets 13 and 14. And a plurality of brackets 18 fixed to the outer peripheral side of the chain 16. A plurality of tool pots 10 are respectively attached to the brackets 18. In the transfer mechanism 12 having such a structure, one of the sprockets 13 is rotationally driven by a motor (not shown) so that a plurality of tool pots 10 are circulated along a predetermined path together with the chain 16. .

  As shown in FIGS. 1 and 2, the tool pot 10 is attached to the bracket 18 so as to be rotatable. In the range where the tool pot 10 is transferred, except for the split outlet 15b provided on the lower end side of the magazine base 11, the inner wall 15a of the rail 15 provided along the outer periphery of the magazine base 11 is used. The outer surface of the tool pot 10 is in contact. That is, the rotation of the tool pot 10 is regulated by the inner wall surface 15a. Thereby, the attitude | position of the tool pot 10 is hold | maintained horizontally. And the attitude | position of the tool holder 60 with which the tool pot 10 was mounted | worn is hold | maintained horizontally. Further, the tool 5 held by the tool holder 60 is held horizontally. The state in which the tool 5 is held horizontally is the storage state in the tool magazine 1.

  Further, the indexing outlet 15b is an indexing position to which the tool 5 indexed by the tool magazine 1 is transferred. Only in this indexing position, the tool pot 10 can be rotated from the retracted state to the state in which the tool 5 is directed downward (the state indicated by the two-dot chain line in FIGS. 1 and 2; hereinafter referred to as the replaceable state). It has become. Furthermore, a tilting mechanism (not shown) for rotating the tool pot 10 from the retracted state to the replaceable state or from the replaceable state to the retracted state is disposed at the index position. The tilting mechanism includes a positioning member (not shown) fixed in the magazine base 11, a turning member (not shown) rotatably attached to the outer periphery of the positioning member, and the turning member. A link rod (not shown) is provided. And while maintaining the rotation center of the tool pot 10 at a fixed position with a positioning member, a link rod is moved up and down and a rotation member is rotated. Thereby, the tool pot 10 is rotated from the retracted state to the replaceable state or from the replaceable state to the retracted state. Then, the tool holder 60 that has been transferred to the split outlet 15b and is in a replaceable state is automatically replaced with another tool holder 60 mounted on the spindle of the machine tool by a tool changer (not shown). .

  An actuator case 26 is provided on the upper portion of the magazine base 11. The actuator case 26 houses a motor (not shown) for driving the sprocket 13 and an air cylinder (not shown) for driving the tilting mechanism of the tool pot 10.

  Next, the structure of the tool pot 10 will be described with reference to FIGS. 3 is a left side view of the tool pot 10, FIG. 4 is a plan view of the tool pot 10, FIG. 5 is a cross-sectional view in the direction of arrows AA shown in FIG. 3, and FIG. FIG. 5 is a cross-sectional view in the direction of arrows BB shown in FIG. 4. 3 and 4 is the front side (front side) of the tool pot 10, and the left side is the back side (rear side) of the tool pot 10.

  First, the external structure of the tool pot 10 will be described. As shown in FIGS. 3 and 4, the tool pot 10 includes a bottomed substantially cylindrical main body portion 31 laid horizontally and a pair of substantially circular shapes protruding from the rear end side of the main body portion 31 to the left and right sides. Columnar protrusions 41, 41, a pair of pot arms 32 extending in parallel from the protrusions 41, 41 toward the rear, and the axial center of the pot arm 32 at the tip end thereof in the left-right direction A rotating shaft 34 attached to both ends of the rotating shaft 34 and projecting to the outside of the pot arm 32; a positioning roller 36 rotatably mounted on the outer periphery of the rotating shaft 34 inside the pot arm 32; And a pair of transfer rollers 38 (only one transfer roller 38 is shown in FIGS. 3 and 4) that is rotatable about an axis extending in the front-rear direction. A plate-like locking portion 42 projects from the upper left portion of the opening end of the main body 31 when viewed from the front. The locking portion 42 engages with an engagement groove 69 provided in a flange portion 65 described later of the tool holder 60.

  The rotation shaft 34 is attached to the bracket 18 so as to be rotatable. Further, the positioning roller 36 is fitted inside the positioning member of the tilt mechanism described above when the tool pot 10 is transferred to the indexing position. In order to promote introduction into the positioning member, both end portions of the positioning roller 36 are tapered so as to become narrower toward both sides. Further, when the tool pot 10 is transferred, the transfer roller 38 rotates when it contacts the inner wall surface 15a of the rail 15 (see FIG. 1). This prevents the tool pot 10 and the magazine base 11 from contacting and rubbing.

  Next, the internal structure of the tool pot 10 will be described. As shown in FIGS. 5 and 6, a mortar-shaped mounting hole 43 having a tapered inner diameter that is tapered from the front side of the main body 31 toward the heel side is provided inside the main body 31. Further, on the back side of the mounting hole 43, a columnar insertion hole 44 that communicates with the back side of the mounting hole 43 and extends substantially horizontally toward the rear of the main body 31 is provided. Furthermore, the bottom of the insertion hole 44 is the bottom of the tool holder 60 by bringing a head 63 of a pull stud 62 (described later) of the tool holder 60 into contact with the mounting hole 43 and the insertion hole 44 inside the insertion hole 44. A positioning part 50 for performing positioning is provided. The mounting hole 43 and the insertion hole 44 shown in FIG. 5 correspond to the “mounting hole” of the present invention.

  Further, an escape hole 55 is provided that communicates perpendicularly to the lowermost side of the insertion hole 44 and penetrates the bottom of the main body 31. The escape hole 55 is used to allow the air inside the insertion hole 44 sandwiched between the heads 63 of the pull stud 62 to escape to the outside when a later-described pull stud 62 of the tool holder 60 is inserted into the insertion hole 44. Is. Further, one end of the escape hole 55 on the side of the insertion hole 44 is disposed at a portion excluding the positioning portion 50 with which the head 63 of the pull stud 62 abuts. This is to ensure a sufficient contact area between the head 63 of the pull stud 62 and the positioning portion 50. As a result, the head 63 of the pull stud 62 can be reliably brought into contact with the positioning portion 50, so that it can sufficiently withstand the impact received from the head 63.

  By the way, an elongated columnar through hole 46 that penetrates along the axial center and communicates perpendicularly to the longitudinal direction of the insertion hole 44 is provided inside the protruding portion 41. Inside the through hole 46, a steel ball 49 that moves in the through hole 46 and a coil spring 47 that elastically biases the steel ball 49 toward the insertion hole 44 are inserted. The steel ball 49 is inserted so as not to drop into the insertion hole 44 from the through hole 46. Further, a plug 48 is screwed into the outer end of the through hole 46. That is, the coil spring 47 is disposed between the plug 48 and the steel ball 49. Accordingly, the steel ball 49 is supported so as to be able to be withdrawn and retracted from the through hole 46 toward the insertion hole 44, and usually a part of the steel ball 49 protrudes from the through hole 46 toward the insertion hole 44. When the head 63 of the pull stud 62 of the tool holder 60 is inserted into the insertion hole 44, the head 63 pushes back the steel ball 49 and passes through the steel balls 49, 49, and the steel balls 49, 49. Settles on the neck 64. As a result, the head 63 of the pull stud 62 is engaged with the steel ball 49.

  Next, the structure of the tool holder 60 attached to and detached from the tool pot 10 will be described with reference to FIGS. 7 is a front view of the tool holder 60, FIG. 8 is a left side view of the tool pot 10 to which the tool holder 60 is mounted, and FIG. 9 is a plan view of the tool pot 10 to which the tool holder 60 is mounted. FIG. As shown in FIG. 7, the tool holder 60 includes a frustoconical shank portion 61 that is attached in close contact with a tapered inner peripheral surface of a mounting hole (not shown) provided on the spindle of the machine tool. A substantially cylindrical flange portion 65 extending radially outward from the bottom surface portion of the shank portion 61 and coaxially connected to the shank portion 61; and projecting downward from the lower surface of the flange portion 65; Are provided with a cylindrical tool chuck portion 68 for holding the tool 5, a pull stud 62 fixed to the upper side of the shank portion 61 whose diameter is reduced.

  A grip groove 66 for gripping by the tool changer is provided at the substantially center in the width direction of the outer peripheral surface of the flange portion 65. Further, the flange portion 65 is provided with an engagement groove 69 (see FIGS. 8 and 9) extending in the thickness direction of the flange portion 65. As shown in FIGS. 8 and 9, the engaging groove 69 engages with the engaging portion 42 protruding from the open end of the tool pot 10. Thereby, the attachment position of the tool pot 10 of the tool holder 60 can be controlled.

  Further, a neck portion 64 that is narrowed radially inward is formed on the tip end side of the pull stud 62 that protrudes from the shank portion 61. A tapered shoulder portion 67 that curves so as to spread from the neck portion 64 toward the shank portion 61 is provided at a portion of the neck portion 64 that is close to the upper portion of the shank portion 61. On the other hand, a substantially spherical head 63 is formed at the distal end of the neck 64 and expands radially outward. The head 63 is engaged with the steel balls 49 and 49 protruding into the insertion hole 44 of the tool pot 10, so that the tool holder 60 cannot be removed from the mounting hole 43 of the tool pot 10. .

  Next, a method for attaching the tool holder 60 to the tool pot 10 will be described with reference to FIGS. 10 is a cross-sectional view in the direction of the arrow C-C shown in FIG. 8, FIG. 11 is a cross-sectional view in the direction of the arrow D-D shown in FIG. 9, and FIG. It is an enlarged view of a portion surrounded by a chain line.

  First, the pull stud 62 side of the tool holder 60 shown in FIG. 7 is opposed to the front surface of the tool pot 10 shown in FIGS. Next, the tool holder 60 is inserted into the mounting hole 43 of the tool pot 10 in this state. Then, the head 63 of the pull stud 62 is inserted into the insertion hole 44 from the mounting hole 43. At this time, the head 63 of the pull stud is pushed into the flange side of the insertion hole 44 while pushing back the steel balls 49, 49 protruding into the insertion hole 44 against the bias of the coil spring 47. 10 and 11, the head 63 passes through the steel balls 49 and 49, and at the same time, the steel balls 49 and 49 are pushed by the elastic return force of the coil springs 47 and 47 so as to settle on the neck 64. . As a result, the head 63 of the pull stud 62 is engaged with the steel balls 49. Further, when the head portion 63 is pushed into the outermost side of the insertion hole 44, the head portion 63 comes into contact with the positioning portion 50. As a result, the tool holder 60 can no longer be inserted into the mounting hole 43, so that the tool holder 60 is positioned.

  When the tool holder 60 is positioned, a gap 90 is formed between the open end of the tool pot 10 and the flange portion 65 of the tool holder 60 as shown in FIG. Further, a slight gap 91 is also formed between the inner surface of the open end of the tool pot 10 and the outer peripheral surface of the shank portion 61 of the tool holder 60. That is, when the tool holder 60 is positioned, the shank portion 61 and the flange portion 65 of the tool holder 60 do not contact the open end of the tool pot 10. This can prevent the shank portion 61 from being damaged or the flange portion 65 from colliding with the open end of the tool pot 10.

  Further, when the head portion 63 of the pull stud 62 is inserted into the insertion hole 44, the air sandwiched between the flange side of the insertion hole 44 and the head portion 63 of the pull stud 62 is passed through the escape hole 55. Can escape to the outside. Thereby, the head 63 of the pull stud 62 can be smoothly inserted into the insertion hole 44.

  As shown in FIGS. 8 and 9, the positioning of the tool holder 60 is completed, and at the same time, the engaging portion 69 is engaged with the engaging portion 42 protruding from the open end of the tool pot 10. Thereby, the flange portion 65 of the tool holder 60 is securely fixed to the tool pot 10, and the mounting of the tool holder 60 to the tool pot 10 is completed.

  In addition, when the tool holder 60 of the present embodiment is mounted in the taper mounting hole (not shown) of the spindle of the machine tool, the outer peripheral surface of the shank portion 61 is brought into close contact with the inner peripheral surface of the taper mounting hole. This is a single-surface-constrained holder that is positioned by the movement. On the other hand, there is a known two-surface constraining type holder that performs positioning with higher accuracy by bringing the shank part into close contact with the inner peripheral surface of the taper mounting hole and at the same time bringing the flange part into close contact with the tip of the spindle of the machine tool. It has been. Even such a two-surface-constrained tool holder can be attached to the tool pot 10 according to the present invention.

  Next, the case where the two-surface restraint type tool holder 160 is mounted on the tool pot 10 will be described with reference to FIGS. 13 and 14. FIG. 13 is a cross-sectional view showing a state in which the two-side restraint type tool holder 160 is attached to the tool pot 10 shown in FIG. 5, and FIG. 14 shows the two-side restraint type in the tool pot 10 shown in FIG. It is sectional drawing which shows the state with which the tool holder 160 of this was mounted | worn. The two-surface constrained tool holder 160 has almost the same structure as the one-surface constrained tool holder 60 shown in FIG. 7, and therefore the same structural parts will be described with the same reference numerals.

  For example, in the two-surface constraint type tool holder 160 shown in FIGS. 13 and 14, the length of the shank portion 161 in the axial direction is set to the one-surface constraint type tool holder 60 in order to bring the flange portion 65 into close contact with the tip of the main shaft. It is slightly shorter than the length of the shank portion 61 in the axial direction. Therefore, when the two-surface constrained tool holder 160 is inserted into the mounting hole of the conventional tool pot corresponding only to the one-surface constrained tool holder 60, the flange portion 65 of the tool holder 160 collides with the open end of the tool pot. Resulting in. Therefore, in the tool pot 10 according to the present invention, the head 63 of the pull stud 62 of the tool holder 160 is brought into contact with the positioning unit 50 before the flange portion 65 of the tool holder 160 collides with the open end of the tool pot 10. Can be touched. That is, since the opening end of the tool pot 10 and the flange portion 65 of the tool holder 160 do not collide, not only the one-surface-constrained tool holder 60 but also the two-surface-constrained tool holder 160 is attached to the tool pot 10. Can be installed.

  As described above, the tool magazine 1 of the present embodiment includes a plurality of tool pots 10 to which the tool holder 60 is attached and detached. The tool pot 10 includes a bottomed cylindrical main body 31. A mounting hole 43 into which the shank portion 61 of the tool holder 60 is inserted is provided inside the main body portion 31, and an insertion hole 44 into which the pull stud 62 is inserted is provided at the back side. Further, the positioning portion 50 for positioning the tool holder 60 in the mounting hole 43 and the insertion hole 44 by bringing the head 63 of the pull stud 62 of the tool holder 60 into contact with the insertion hole 44 at the very bottom. Is provided. Thus, the head 63 of the pull stud 62 can be brought into contact with the positioning portion 50 before the shank portion 61 of the tool holder 60 comes into contact with the open end of the tool pot 10. And since the shank part 61 of the tool holder 60 does not contact the opening end of the tool pot 10, it can prevent that the outer peripheral surface of the shank part 61 is damaged. That is, it is possible to prevent the positioning accuracy of the tool holders 60 and 160 from being lowered when being attached to the attachment hole of the spindle of the machine tool.

  Needless to say, the tool magazine of the present invention is not limited to the above-described embodiment, and various modifications are possible. For example, in the above-described embodiment, the positioning portion is provided at the bottom of the insertion hole 44 of the tool pot 10, and the head 63 of the pull stud 62 of the tool holder 60 is brought into contact with the positioning portion. The part may be located anywhere as long as it is inside the mounting hole 43 or the insertion hole 44 of the tool pot 10. Further, the part of the tool holder 60 to be brought into contact with the positioning part is not limited to the head 63 of the pull stud 62 but may be another part.

  For example, the tool pot 100 as a modification shown in FIG. 15 has basically the same structure as the tool pot 10 shown in FIG. 5, but at the boundary between the mounting hole 43 and the insertion hole 44, radially inward. A stepped portion 45 having a reduced diameter is provided. Then, as shown in FIG. 16, the tool holder 160 is brought into contact with the shoulder portion 67 of the pull stud 62 of the tool holder 160 (or the tool holder 60) with respect to the step portion 45, as in the above embodiment. Can be positioned.

  Moreover, in the said embodiment, although the escape hole 55 is provided so that it may penetrate orthogonally to the lowermost side of the insertion hole 44, and may penetrate the bottom part of the main-body part 31, it is shown in FIG. One end of the escape hole 155 may be provided in the positioning unit 50 as in a modified tool pot 150. The escape hole 155 extends substantially horizontally through the bottom of the main body 31 so as to be in the same direction as the insertion direction of the tool holder 60. That is, since the direction in which the head 63 of the pull stud 62 abuts on the positioning portion 50 and the direction in which air escapes from the escape hole 155 can be made the same, the innermost side of the insertion hole 44 and the head 63 of the pull stud 62 can be made. The air sandwiched between the two can be easily removed. Therefore, the tool holder 60 can be more smoothly inserted into the mounting hole 43 and the insertion hole 44 of the tool pot 150.

  The tool storage device of the present invention is applicable to a tool storage device that stores a tool pot to which a tool holder is attached and detached.
