- the first biasing member 75 and the second biasing member 76 are both tension springs.
- the first biasing member 75 has one end attached to the first gripping member 77 and the other end attached to the first base member 73.
- the second biasing member 76 has one end attached to the second gripping member 78 and the other end attached to the second base member 74.
- the first biasing member 75 biases the first gripping member 77 toward the gripping angle Ga.
- the second biasing member 76 biases the second gripping member 78 toward the gripping angle Ga.
- a first roller 77r is attached to the first gripping member 77.
- a second roller 78r is attached to the second gripping member 78.
- a magazine side cam Cm is provided on the X- direction side of the arm 70.
- the magazine side cam Cm is attached to the frame or housing of the tool changer 80.
- a spindle side cam Cs is provided on the X+ direction side of the arm 70.
- the spindle side cam Cs is attached to the frame or housing 96 of the spindle assembly 95, and rises and falls together with the spindle assembly 95. Note that the "spindle side cam Cs" may be read as a "pressure member".
- the underside of the end of the first base member 73 on the X-direction side forms a first abutment surface 73s.
- the first abutment surface 73s abuts against the first gripping member 77 at a position that prevents rotation toward the gripping angle Ga, thereby limiting the range of rotation of the first gripping member 77 toward the gripping angle Ga.
- a first abutment surface 77s that abuts parallel to the first abutment surface 73s from below is provided on the upper part of the first gripping member 77.
- the underside of the end of the second base member 74 on the X+ direction side forms a second abutment surface 74s.
- the second abutment surface 74s abuts against the second gripping member 78 at a position that prevents rotation toward the gripping angle Ga, thereby limiting the range of rotation of the second gripping member 78 toward the gripping angle Ga.
- a second abutment surface 78s that abuts parallel to the second abutment surface 74s from below is provided on the upper part of the second gripping member 78.
- the above explanation is for the arm 70 when viewed in the first basic state bS1.
- the explanation for the arm 70 when viewed in the second basic state bS2 is similar to the above explanation, except that "first" and "second" are read as the other, and the reference numerals are read as appropriate.
- the first gripping member 77 shown in FIG. 22 repeatedly collides with the first abutment surface 73s by repeatedly rotating toward the gripping angle Ga side and toward the release angle Ra side. If the first gripping member 77 slides against the first abutment surface 73s during this collision, wear will progress on the first abutment surface 73s and the first gripping member 77, which may cause malfunction of the arm 70. Similarly, if the second gripping member 78 slides against the second abutment surface 74s, wear will progress on the second abutment surface 74s and the second gripping member 78, which may cause malfunction of the arm 70.
- the first abutment surface 73s extends along a first imaginary plane Vp1 that includes the entire rotation axis 77c of the first gripping member 77, i.e., the entire center line of the first shaft material Ax1.
- the tangent direction of the rotation direction of the first gripping member 77 on the first abutment surface 73s necessarily faces the direction perpendicular to the surface of the first abutment surface 73s. This suppresses the generation of a force that would cause the first gripping member 77 to shift parallel to the first abutment surface 73s.
- the tangent direction of the rotation direction of the first gripping member 77 at the first abutment surface 73s is inclined with respect to the perpendicular direction of the first abutment surface 73s. This makes it easier for a force to be applied that causes the first gripping member 77 to shift parallel to the first abutment surface 73s.
- this embodiment makes it possible to reduce sliding when the first gripping member 77 collides with the first abutment surface 73s.
- the second abutment surface 74s extends along the second imaginary plane Vp2 that includes the entire rotation axis 78c of the second gripping member 78, i.e., the entire center line of the second shaft material Ax2. Therefore, for the same reason as in the case of the first abutment surface 73s, sliding can be suppressed when the second gripping member 78 collides with the second abutment surface 74s.
- the second problem to be solved by the arm 70 of this embodiment will be described.
- the power to the arm rotation device 60 is usually also turned off.
- the arm 70 is released from the current rotation phase that was held by the arm rotation device 60.
- the spindle side cam Cs is pressing against the second gripping member 78 or when the spindle side cam Cs is pressing against the first gripping member 77, if the power to the arm rotation device 60 is turned off, the arm 70 will rotate due to the pressing force.
- the arm 70 is configured as follows.
- a plate-shaped first rotation stop member 73z that protrudes from the first base member 73 in the Y+ direction is provided on the X- direction side of the upper surface of the first base member 73.
- a plate-shaped second rotation stop member 74z that protrudes from the second base member 74 in the Y- direction is provided on the X+ direction side of the upper surface of the second base member 74.
- the first rotation stop member 73z and the second rotation stop member 74z are collectively referred to as "rotation stop members 73z, 74z.”
- the second rotation stop member 74z is disposed to the side of the spindle side cam Cs in the Y+ direction with a small clearance CLh as shown in FIG. 18. This second rotation stop member 74z restricts the rotation of the arm 70 when the power supply to the arm rotation device 60 is turned OFF.
- the above explanation is for the arm 70 when viewed in the first basic state bS1.
- the explanation for the arm 70 when viewed in the second basic state bS2 is similar to the above explanation, except that "first" and "second" are read as the other, and the reference numerals are read as appropriate.
- control device 51 controls each drive device, including the magazine rotation device 39, the arm rotation device 60, and the arm lifting device 55.
- the specific procedure for tool replacement based on the control by the control device 51 will be described below.
- the arm 70 in the initial state, the arm 70 is at the uppermost point. At this time, the arm 70 may be in either the first basic state bS1 or the second basic state bS2. Below, a case where the arm 70 is in the first basic state bS1 in the initial state will be described.
- the tool pot 10 at the replacement position ep is positioned at a storage angle Sa according to the profile of the pot drive cam 41.
- the first gripping member 77 is positioned at a release angle Ra according to the profile of the magazine-side cam Cm, and the second gripping member 78 is also positioned at a release angle Ra according to the profile of the spindle-side cam Cs.
- the first gripping member 77 rotates to a gripping angle Ga according to the profile of the magazine side cam Cm, and grips the next tool to be used Tn in the tool pot 10 at an exchange angle Ea. From that state, as shown in FIG. 27, the first gripping member 77 descends to remove the next tool to be used Tn from the tool pot 10.
- the second gripping member 78 rotates toward the gripping angle Ga in accordance with the profile of the spindle-side cam Cs to grip the previously used tool Tp on the spindle 97. From this state, as shown in FIG. 28, the second gripping member 78 descends relative to the spindle 97 to remove the previously used tool Tp from the spindle 97.
- the arm 70 is rotated 180° around the vertical axis by the arm rotation device 60.
- This rotation changes the state from the first basic state bS1 to the second basic state bS2.
- the second gripping member 78 and the previously used tool Tp are on the X- side
- the first gripping member 77 and the next tool to be used Tn are on the X+ side.
- the tool pot 10 at the exchange position ep rotates to the exchange angle Ea according to the profile of the pot drive cam 41 as shown in FIG. 31, and then rotates again to the storage angle Sa as shown in FIG. 32 and FIG. 33.
- the second gripping member 78 rises as shown in FIG. 31 to attach the previously used tool Tp to the tool pot 10 at the exchange angle Ea. From that state, as shown in FIG. 32, the second gripping member 78 rotates toward the release angle Ra in accordance with the profile of the magazine-side cam Cm, and releases its grip on the previously used tool Tp.
- the above describes the case where the initial state is the first basic state bS1.
- the explanation for the case where the initial state is the second basic state bS2 is similar to the above explanation, except that "first" and "second” are read as the other, and the symbols are read as the corresponding ones.
- the fixed member 34 is fixed to the swivel member 35 and extends in the swivel direction.
- the fixed member 34 has support parts 344 arranged in the swivel direction for each tool pot 10.
- a biasing member 31 is provided for each tool pot 10.
- Each biasing member 31 is attached to the corresponding tool pot 10 and the corresponding support part 344, and biases the corresponding tool pot toward the storage angle Sa. Therefore, a single fixed member 34 can support multiple biasing members 31 on the swivel member 35. Therefore, multiple biasing members 31 can be supported on the swivel member 35 without providing a support member for supporting the biasing member 31 on the magazine base 38 for each tool pot 10. This reduces the assembly man-hours for the tool magazine 30 and the manufacturing cost.
- the biasing member 31 is a tension spring.
- Each support portion 344 has a key shape that can engage with the end of the biasing member 31. This allows the fixing member 34 to be realized with a simple shape.
- the fixing member 34 is annular and goes around in the rotation direction of the rotating member 35. Therefore, the strength of the fixing member 34 can be ensured more efficiently than when the fixing member 34 is C-shaped, for example.
- the fixing member 34 is made of metal. This also ensures the strength of the fixing member 34 efficiently.
- the clamp mechanism 12 is attached to the clamp attachment hole 18h.
- the posture-maintaining member 13 is inserted into the insertion hole 18v and maintains the posture of the clamp mechanism 12 relative to the pot body 18. Therefore, the posture of the clamp mechanism 12 relative to the pot body 18 can be maintained without using screws or the like. This makes it possible to select a material for the pot body 18 that is difficult to secure with screws in terms of strength, and to simplify the structure of the pot body 18. This leads to a reduction in weight, size, and cost of the tool pot 10.
- the posture-maintaining member 13 is formed with an insertion hole 13v that allows the pull stud bolt pB to pass through to the clamp mechanism 12 when the pull stud bolt pB is inserted into the insertion hole 18v. Therefore, the posture-maintaining member 13 does not impede the passage of the pull stud bolt pB, and the outer shape of the posture-maintaining member 13 is necessarily larger than the outer shape of the pull stud bolt pB. This allows the size of the posture-maintaining member 13 to be sufficiently large within a limited space such as the inside of the pot body 18. This allows the posture of the clamp mechanism 12 relative to the pot body 18 to be sufficiently firmly maintained.
- the tool pot 10 can be made lighter, smaller, and less expensive, while still maintaining a sufficiently strong position of the clamp mechanism 12 relative to the pot body 18.
- a protrusion 131 that protrudes toward the clamp mechanism 12 is formed on the portion of the posture maintaining member 13 on the side of the insertion hole 13v. As shown in Figure 10, the protrusion 131 engages with the clamp mechanism 12, thereby maintaining the posture of the clamp mechanism 12 relative to the pot body 18. This allows the posture of the clamp mechanism 12 to be maintained with a simple shape.
- the insertion hole 13v has a tapered shape that narrows toward the clamp mechanism 12. Therefore, the insertion hole 13v can guide the pull stud bolt pB into the clamp mechanism 12.
- the pot body 18 shown in FIG. 10 is made of resin. This allows the tool pot 10 to be made lighter, smaller, and less expensive.
- the clamp mechanism 12 and the posture-maintaining member 13 are made of metal. This ensures that the clamp mechanism 12, which actually holds the tool, and the posture-maintaining member 13, which maintains its posture, have sufficient strength.
- the posture-maintaining member 13 maintains the posture of the clamp mechanism 12 relative to the pot body 18 by engaging with the clamp base 122, which houses a pair of contact members 127 and a pair of biasing members 126 inside. This allows the posture of the clamp mechanism 12 to be maintained in a simple manner.
- the pivot shaft member 67 is provided with a through hole 67v that extends vertically and whose upper end communicates with the internal space iS.
- a base plate 72 is attached to the lower end of the pivot shaft member 67.
- a communication passage Ph is formed between the pivot shaft member 67 and the base plate 72, connecting the lower end of the through hole 67v to the outside of the outer circumferential surface of the pivot shaft member 67. Therefore, even if cutting fluid enters and accumulates in the internal space iS, the cutting fluid can be discharged through the through hole 67v and the communication passage Ph to the in-machine space wS.
- the first abutment surface 73s extends along the first imaginary plane Vp1 that includes the entire rotation axis 77c of the first gripping member 77, i.e., the entire center line of the first shaft material Ax1.
- the tangent direction of the rotation direction of the first gripping member 77 on the first abutment surface 73s necessarily faces the direction perpendicular to the surface of the first abutment surface 73s.
- the first gripping member 77 has a first contact surface 77s that contacts the first abutment surface 73s in parallel. Therefore, compared to when, for example, a roller or the like of the first gripping member 77 makes linear contact with the first abutment surface 73s, the contact area of the first gripping member 77 with the first abutment surface 73s can be increased, thereby reducing wear between the first abutment surface 73s and the first gripping member 77.
- the second gripping member 78 has a second contact surface 78s that contacts the second abutment surface 74s in parallel. Therefore, for the same reason as above, wear between the second abutment surface 74s and the second gripping member 78 can be reduced.
- the arm 70 is provided with a first rotation stop member 73z and a second rotation stop member 74z.
- the second rotation stop member 74z stops the rotation by abutting against the spindle side cam Cs at a position that prevents the rotation due to the pressure.
- the first rotation stop member 73z stops the rotation by abutting against the spindle side cam Cs at a position that prevents the rotation due to the pressure.
- the first rotation stop member 73z or the second rotation stop member 74z can prevent the arm 70 from rotating due to the pressure.
- This embodiment differs from the first embodiment in that the magazine 30 shown in FIG. 4 includes a plurality of tool pots 20 shown in FIG. 34 instead of a plurality of tool pots 10. Note that the pot rollers are not shown in FIG. 34. Also, as shown in FIG. 36, this embodiment differs in that an engagement portion Eg is formed at the base end of each tool T instead of a pull stud bolt pB.
- the engagement portion Eg has an upper portion EgU and a lower portion EgD. The upper portion EgU protrudes more toward the inner circumference of the tool T than the lower portion EgD. Note that the engagement portion Eg may be read as the "end of the tool.”
- the tool pot 20 includes a pot body 28, a cylindrical member 27, a biasing member 22, a piece 23, and a number of contact members 24.
- the pot body 28 is made of resin.
- the cylindrical member 27 is made of metal.
- the biasing member 22 is a metal compression spring.
- the piece 23 is made of metal.
- Each contact member 24 is a metal ball.
- the tool pot 20 is configured as follows when viewed in the state shown in FIG. 35, i.e., when the tool pot 20 is positioned at the exchange angle Ea in the exchange position ep.
- the cylindrical member 27 is fixed inside the pot body 28 with its axis oriented vertically.
- the piece 23 is installed inside the lower end of the cylindrical member 27 so that it can be displaced vertically.
- the space inside the cylindrical member 27 above the piece 23 is referred to as the "storage space sS.”
- the biasing member 22 is stored in the storage space sS.
- a retainer 21 for holding the upper end of the biasing member 22 is attached to the upper end of the cylindrical member 27.
- the biasing member 22 is interposed between the retainer 21 and the piece 23, and biases the piece 23 downward.
- a number of mounting holes 27h are provided through the lower end of the cylindrical member 27. In the bottom view shown in FIG. 38, these mounting holes 27h extend radially in the radial direction of the cylindrical member 27.
- Each contact member 24 is attached to one of the mounting holes 27h. As a result, each contact member 24 is configured to be able to protrude outward from the outer periphery of the cylindrical member 27 and retract inward. Note that although the figure shows three contact members 24, the number may be two or less, or four or more.
- the piece 23 has a tapered surface 23t at its lower end.
- the tapered surface 23t presses the multiple contact members 24, causing them to protrude outward from the outer periphery of the lower end of the tubular member 27.
- a communication passage Pv is formed in the bridge 23.
- the communication passage Pv is configured as follows:
- the communication passage Pv extends from the upper end to the lower end of the piece 23, connecting the storage space sS with the outside.
- a communication hole 23v is formed as the communication passage Pv, as shown in FIG. 39.
- the communication hole 23v penetrates the piece 23 in the vertical direction.
- a communication groove 23d may be formed as the communication passage Pv, as shown in FIG. 40.
- the communication groove 23d is recessed into the outer circumferential surface of the piece 23 and extends in the vertical direction. Note that the above explanation is for the case where the tool pot 20 is arranged at the exchange angle Ea in the exchange position ep, as described above.
- the coolant if coolant or the like infiltrates from the internal space wS shown in FIG. 35 into the storage space sS, the coolant is discharged from the communication passage Pv.
- the embodiment described above can be modified, for example, as follows.
- the arm 70 shown in Fig. 16 may have three or more gripping members 77, 78 instead of two.
- the arm rotation device 60 shown in Fig. 2 may rotate the arm 70 by 120° instead of 180°.
- the position-maintaining member (13) has a protrusion (131) protruding toward the clamp mechanism (12) at a portion on the insertion hole (13v) side, The projection (131) engages with the clamp mechanism (12), thereby maintaining the position of the clamp mechanism (12) relative to the pot body (18).
- the insertion hole (13v) has a tapered shape that decreases in diameter as it advances toward the clamp mechanism (12). 3.
- the clamp mechanism (12) comprises a clamp base (122) extending in the longitudinal direction of the clamp mounting hole (18h) and configured to allow the pull stud bolt (pB) to be inserted therein, a pair of contact members (127) installed inside the clamp base (122) so as to be displaceable in the longitudinal direction of the clamp mounting hole (18h), and a pair of urging members (126) that urge the pair of contact members (127) toward the pull stud bolt (pB) when the pull stud bolt (pB) is inserted into the clamp base (122), and is configured to hold the pull stud bolt (pB) with the pair of contact members (127),
- the attitude of the clamp mechanism (12) relative to the pot body (18) is maintained by the attitude maintaining member (13) engaging with the clamp base (122). 5.
