Abstract

PROBLEM TO BE SOLVED: To take out an O-ring which has been finished in a washing process without causing the adhesion of foreign objects during displacement from a standby position to a takeout position.SOLUTION: The O-ring 2 and a tool 3 which have been finished in the washing process are assembled to a base 4a, and a collar up/down chuck 5 is moved upward, thus displacing the O-ring 2 at the uppermost position to the takeout position so that the O-ring 2 at the uppermost position does not contact with the other member in the middle of the displacement to the takeout position. The O-ring which is an object to be taken out displaced to the takeout position is taken out by a suction head 9. After assembling the O-ring 2 and the tool 3 which have been finished in the washing process to the base 4a, the O-ring 2 can be taken out without contacting with the other member by only displacing a pole collar 11 which has been finished in the washing process.

Description

  The present invention relates to an O-ring take-out apparatus that takes out an O-ring to be taken out by moving it from a standby position to a take-out position, and a method therefor.

  An O-ring is frequently used as a means for keeping the contact portion between members airtight or watertight. For example, there is a method disclosed in Patent Document 1 as a method of taking out this type of O-ring for assembling it on a workpiece. In the method disclosed in Patent Document 1, a plurality of first supply plates fixed to the equipment and a second supply plate fixed to the equipment so as to be slidable on the first supply plate are used. The O-rings are arranged in tandem with the supply cylinder, and the second supply plate slides on the first supply plate, so that the O-ring arranged at the lowest position (standby position) of the supply cylinder is The O-ring extruded by the end face of the supply plate 2 moves to the take-out position. Then, the O-ring that has moved to the take-out position is taken out.

Utility Model Registration No. 2511500

  By the way, in the O-ring, it is desirable that foreign matters (human hair, clothing fibers, etc.) do not adhere so as to securely hold the contact portion between the members airtight or watertight. However, in the method disclosed in Patent Document 1 described above, in the step of moving the O-ring to be extracted from the standby position to the extraction position, the O-ring is slid on the first supply plate that cannot be cleaned. The O-ring is moved from the standby position to the take-out position, so even if the O-ring arranged in the supply cylinder is in a state where the cleaning process has been completed (foreign matter removed), the O-ring is supplied to the first supply. There is a risk that foreign matter may adhere to the O-ring in the process of sliding on the plate. As a result, if the O-ring with the foreign matter attached is taken out and the O-ring with the foreign matter attached is assembled to a workpiece, for example, in a subsequent process, the contact portion between the members cannot be kept airtight or watertight. There is a problem of inducing a bug.

  The present invention has been made in view of the above-described circumstances, and the purpose thereof is to allow the O-ring that has been subjected to the cleaning process to be removed without being adhered while moving from the standby position to the removal position. An O-ring take-out device and a method thereof are provided.

  According to the invention described in claims 1 and 5 to 7, the facility (4) is detachably supported by the base (4 a) of the facility (4), and the support member (10 ) And a movable member (11) held movably with respect to the movable member (11). The movable member (11) in the jig (3) detached from the base (4a) and cleaned. ) To move the O-ring (2) from the standby position to the removal position. Thereby, since the jig (3) can be attached to and detached from the base (4a), the jig (3) can be cleaned. As a result, the movable member (11 in the cleaned jig (3) can be cleaned. ), The cleaned O-ring (2) can be taken out without touching other members (non-cleaning members) while being moved from the standby position to the take-out position.

  According to the invention described in claims 2 and 8, the support member (10) has the rod-shaped shaft member (10), and the movable member (11) is movable in the axial direction of the shaft member (10). It has a moving member (11), and the O-ring (2) is moved from the standby position to the take-out position by moving the moving member (11) from one end side to the other end side of the shaft member (10). . Accordingly, the O-ring (2) to be taken out can be realized with a simple configuration in which the moving member (11) moves from one end side to the other end side of the shaft member (10).

  According to the invention described in claims 3 and 9, when a part of the O-rings (2) is taken out of the plurality of O-rings (2), the remaining O-rings other than the part of the O-rings (2) are removed. A part of the O-ring (2) was taken out while (2) was held in an undisplaceable state. Thereby, it is possible to prevent the remaining O-ring (2) from being taken out together with a part of the O-ring (2) to be taken out due to, for example, surface tension acting. Only the O-ring (2) can be reliably removed.

  According to the invention described in claims 4 and 10, the O-ring (2) in contact with at least a part of the remaining O-rings (2) is held in an undisplaceable state. Then, a part of the O-ring (2) was taken out. Accordingly, an O-ring that is in contact with at least a part of the O-ring (2) to be taken out of the remaining O-rings (2) without requiring a configuration that holds all of the remaining O-rings (2). (2) can be realized with the minimum required configuration.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 schematically shows the overall configuration of the O-ring take-out device. The O-ring take-out device 1 includes, for example, a jig 3 into which an O-ring 2 (five O-rings 2a to 2e in FIG. 1) made of, for example, silicon rubber, and a base on which the jig 3 can be assembled. 4a, a collar upper and lower chuck 5, a cutting chuck 6 (corresponding to a holding means), a pair of light projecting sensors 7 and a light receiving sensor 8, and a suction head 9 (corresponding to an extracting means). . The jig 3 and the base 4 a are components of the equipment 4.

  The jig 3 is configured by combining a pole 10 (corresponding to a support member and a shaft member) and a pole collar 11 (corresponding to a movable member and a moving member). The pole 10 includes a columnar pole body 12 having an outer diameter slightly smaller than the inner diameter of the O-ring 2, and a column whose diameter is smaller than that of the pole body 12 on one end side (lower end side in FIG. 1) of the pole body 12. The mounting shaft portion 13 is shaped so that the axial center of the pole body 12 and the axial center of the mounting shaft portion 13 coincide with each other. The pole collar 11 is formed in an annular shape whose inner diameter is slightly larger than the outer diameter of the pole body 12, and is movable in the axial direction of the pole 10 (pole body 12) (the direction indicated by the arrow A1-A2 in FIG. 1). Is inserted into the pole body 12.

  The pole 10 and the pole collar 11 are made of, for example, stainless steel or Teflon (registered trademark) resin, considering that the material of the O-ring 2 is silicon rubber in order to reduce the resistance with the O-ring 2. It is desirable that the outer peripheral surface portion be provided with a bicoat (a coating of a composite organic material combined with an organic material excellent in lubricity and releasability). The jig 3 is fitted into the mounting hole 14 formed in the base 4a with the mounting shaft portion 13 of the pole 10, and the axial direction thereof is the plane direction of the base 4a (in FIG. 1, arrows B1-B2). In a fixed state, it can be attached and detached so as to be substantially perpendicular to the direction shown in FIG.

  The collar upper and lower chucks 5 are arranged so as to support the lower surface portion 11a of the pole collar 11 in a state where the jig 3 is assembled to the base 4a. In this case, the collar upper and lower chucks 5 may support the lower surface portion 11a of the pole collar 11 at two equally spaced points having an interval of 180 degrees in the circumferential direction of the pole body 12, or in the circumferential direction of the pole body 12. The lower surface portion 11a of the pole collar 11 may be supported at three equally spaced points having an interval of 120 degrees, or the pole collar 11 may be supported at four equally spaced points having a 90 degree interval in the circumferential direction of the pole body 12. The lower surface portion 11a may be supported. In a state where a plurality of O-rings 2 are inserted in a row in the pole 10 (pole body 12), the O-ring 2 (the O-ring 2e in FIG. Only contacts the upper surface portion 11 b of the pole collar 11.

  The light projecting sensor 7 and the light receiving sensor 8 are arranged to face each other at a position close to the other end side (the upper end side in FIG. 1) of the pole body 12 in a state where the jig 3 is assembled to the base 4a. In this case, if the O-ring 2 is not present (not moved) on the optical axis (indicated by a broken line arrow P in FIG. 1) connecting the light projecting sensor 7 and the light receiving sensor 8, the light projecting sensor 7 The light emitted from the light receiving sensor 8 is received by the light receiving sensor 8. If the O-ring 2 is present on the straight line connecting the light projecting sensor 7 and the light receiving sensor 8 (if moved), the light emitting sensor 7 The thrown light is blocked by the O-ring 2 and cannot be received by the light receiving sensor 8. A position where the light projected from the light projecting sensor 7 is not blocked by the O-ring 2 is a standby position, and a position where light projected from the light projecting sensor 7 is blocked by the O-ring 2 is a take-out position. That is, FIG. 1 shows a mode in which the O-ring 2a is arranged at the take-out position and the O-rings 2b to 2e are arranged at the standby position.

  The cutting chuck 6 is disposed below the light projecting sensor 7 and the light receiving sensor 8, and has a holding position (a position indicated by a solid line in FIG. 1) and a non-holding position (a position indicated by a broken line in FIG. 1, an initial position). ) In a horizontal direction (a direction orthogonal to the axial direction of the pole 10). When the cutting chuck 6 is moved to the holding position, the O-ring 2 disposed immediately below the O-ring 2 (the O-ring 2a in FIG. 1) whose contact surface portion 6a is disposed at the removal position. Next, the O-ring 2 that is moved to the take-out position is in contact with the O-ring 2b in FIG. 1, and an appropriate pressing force in the radial direction (direction toward the axis center) is applied to the O-ring 2. By providing, the O-ring 2 is held indisplaceable. The contact surface portion 6a in contact with the O-ring 2 is formed by a flat surface.

  The contact surface portion 6 of the cutting chuck 6 is processed so as not to damage the contact portion of the O-ring 2 even when contacting the O-ring 2. Similarly to the collar upper and lower chucks 5, the cutting chuck 6 may hold the O-ring 2 at two equally spaced points having a spacing of, for example, 180 degrees in the circumferential direction of the pole body 12. The O-ring 2 may be held at three equally spaced points having an interval of 120 degrees in the circumferential direction of the ring, or the O-rings at four equally spaced points having an interval of 90 degrees in the circumferential direction of the pole body 12, for example. 2 may be held.

  The suction head 9 has an intake hole 15, and a concave suction surface portion 9 a is formed along the outer shape of the O-ring 2 on the lower surface side thereof, and the O-ring 2 disposed at the take-out position is evacuated. While being taken out from the jig 3 by suction and sucked onto the suction surface portion 9a, it can be moved in the vertical direction and the horizontal direction by a suction head transport mechanism 16 (not shown in FIG. 1, see FIG. 2).

  FIG. 2 is a functional block diagram showing the electrical configuration of the O-ring extraction device 1 described above. The control unit 17 is configured mainly as a microcomputer, and connects the above-described collar upper and lower chucks 5, the cutting chuck 6, the light projecting sensor 7, the light receiving sensor 8, the suction head 9, and the suction head transport mechanism 16 and stores them in advance. By executing the control program, the operations of the collar upper and lower chucks 5, the cutting chuck 6, the light projecting sensor 7, the light receiving sensor 8, the suction head 9, and the suction head transport mechanism 16 are controlled, and the O-ring take-out device 1 operation is controlled.

  The collar upper and lower chucks 5 move upward along the axial direction of the pole 10 when a drive command signal is input from the control unit 17. The drive command signal output from the control unit 17 to the collar upper and lower chucks 5 is, for example, a level signal, and the collar upper and lower chucks 5 extend along the axial direction of the pole 10 during the period when the drive command signal is input from the control unit 17. Move upward. In this manner, the collar upper and lower chucks 5 move upward along the axial direction of the pole 10, and the collar upper and lower chucks 5 press the lower surface portion 11 a of the pole collar 11, so that the pole collar 11 is also poled. The O-ring 2 fitted in the pole 10 also moves upward along the axial direction of the pole 10.

  The cutting chuck 6 generates a moving force in a direction from the non-holding position to the holding position when a drive command signal is input from the control unit 17. The drive command signal output from the control unit 17 to the cutting chuck 6 is, for example, a level signal, and the cutting chuck 6 moves from the non-holding position to the holding position in a period in which the driving command signal is input from the control unit 17. Generates a moving force in the direction. That is, before the cutting chuck 6 comes into contact with the O-ring 2 (before reaching the holding position), the moving force of the cutting chuck 6 becomes a propulsive force that advances from the non-holding position to the holding position, and the cutting chuck 6 moves to the O-ring. After contact with 2 (after reaching the holding position), the moving force of the cutting chuck 6 becomes a pressing force for pressing the O-ring 2 in the radial direction. Note that, when the input of the drive command signal from the control unit 17 is stopped, the cutting chuck 6 moves from the holding position to the non-holding position (returns to the initial position).

  When a light projection command signal is input from the control unit 17, the light projection sensor 7 emits light having straightness. The light projection command signal output from the control unit 17 to the light projection sensor 17 is, for example, a level signal, and the light projection sensor 7 projects light during a period in which the light projection command signal is input from the control unit 17.

  When the light receiving sensor 8 receives the light cast from the light projecting sensor 7, it outputs a light receiving signal to the control unit 17. The light receiving signal output from the light receiving sensor 8 to the control unit 17 is, for example, a level signal, and the control unit 17 detects that the light projected from the light projecting sensor 7 during the period when the light receiving signal is input from the light receiving sensor 8 8 and it is determined that the O-ring 2 does not exist at the take-out position.

  When the suction head 9 is positioned directly above the O-ring 2 to be taken out, when a suction command signal is input from the control unit 17, the suction head 9 is lowered from the suction standby position to the suction execution position, and the O-ring 2 is vacuum-sucked. As a result, it is adsorbed to the adsorption surface portion 9a, and the O-ring 2 is raised (returned) from the adsorption execution position to the adsorption standby position with the O-ring 2 adsorbed to the adsorption surface portion 9a. The suction command signal output from the control unit 17 to the suction head 9 is, for example, a pulse signal. When the suction command signal is input from the control unit 17, the suction head 9 performs the above-described series of operations. The suction head 9 moves up and down if it does not need to move up and down due to the weight of the O-ring 2, the suction force that sucks the O-ring 2, and the relative positional relationship with the O-ring 2 to be taken out. Alternatively, the O-ring 2 may be adsorbed to the adsorption surface portion 9a by vacuum adsorption.

  In addition, when the suction head 9 is positioned directly above the work 18 to be assembled with the O-ring 2, when the suction break command signal is input from the control unit 17, the O-ring 2 is sucked to the suction surface portion 9a. In this state, the O-ring 2 adsorbed on the adsorption surface portion 9a is naturally dropped from the adsorption surface portion 9a by adsorbing and decomposing from the adsorption destruction standby position to the adsorption destruction execution position, and adsorbing from the adsorption destruction execution position. Ascend to the destruction standby position. The suction destruction command signal output from the control unit 17 to the suction head 9 is, for example, a pulse signal. When the suction head 9 receives the suction destruction command signal from the control unit 17, the above-described series of operations is performed. If the suction head 9 does not need to move up and down due to the relative positional relationship with the workpiece 18, the suction head 9 may be sucked and broken without being moved up and down. Note that the workpiece 18 here is, for example, a component of a pressure sensor. The O-ring 2 is naturally dropped from the suction surface portion 9a of the suction head 9 in this way, and is fitted into a recess 19 formed in an annular shape (along the outer shape of the O-ring 2) on the upper surface portion 18a of the workpiece 18. As a result, the workpiece 18 is assembled.

  When receiving a transport command signal from the control unit 17, the suction head transport mechanism 16 transports (moves) the suction head 9 between the suction standby position and the suction break standby position described above according to a predetermined transport path. The transport command signal output from the control unit 17 to the suction head transport mechanism 16 is, for example, a pulse signal, and when the transport command signal is input from the control unit 17, the suction head transport mechanism 16 performs the above-described series of operations.

Next, the operation of the above configuration will be described with reference to FIGS.
The O-ring 2 and the jig 3 (the pole 10 and the pole collar 11) handled by the operator have been cleaned. The term “cleaning” as used herein refers to an operation for removing foreign matter (which may include an operation for making foreign matter difficult to adhere), for example, spraying high-pressure air or immersing it in a cleaning liquid. In the case of immersion in the cleaning liquid, a drying step for removing the cleaning liquid is also included. In this case, as shown in FIG. 3, the O-ring 2, the pole 10 and the pole collar 11 are first assembled, the stopper 20 is attached to the pole 10, and then the assembled O-ring 2, the pole 10 and the pole are assembled. For example, the O-ring 2, the pole 10, and the pole collar 11 may be cleaned together by injecting high-pressure air from the high-pressure air gun 21 onto the collar 11. Although not shown, the O-ring 2, the pole 10 and the pole collar 11 may be separately cleaned first, and the cleaned O-ring 2, the pole 10 and the pole collar 11 may be assembled. In addition, after the cleaning process is completed, the stopper 20 is removed from the pole 10.

  As shown in FIG. 4, the operator handles the O-ring 2 that has been cleaned in this way and the jig 3 that has been cleaned in a sealed state with a bag 22. The term “sealing” as used herein refers to a state in which foreign matter (human hair, clothing fibers, etc.) does not adhere to the O-ring 2 that has been cleaned and the jig 3 that has been cleaned. The operator opens the bag 22, takes out the O-ring 2 and the jig 3 from the bag 22, and inserts the mounting shaft portion 13 of the pole 10 into the mounting hole portion 14 of the base 4a. The collar upper and lower chucks 5 are assembled in a fixed state so as to be substantially perpendicular to the plane direction of the table 4 a, the collar upper and lower chucks 5 are arranged below the pole collar 11, and the O-ring 2 and the pole collar 11 are supported by the collar upper and lower chucks 5. In this case, it is desirable for the operator to work while gripping a position near the mounting shaft portion 13 of the pole 10, that is, it is desirable not to touch the O-ring 2. Further, the O-ring 2 and the jig 3 are not limited to be integrally assembled to the base 4a, and the O-ring 2 may be assembled to the jig 3 after the jig 3 is assembled to the base 4a. .

  Next, for example, the operator operates the personal computer to cause the control unit 17 to execute the control program, and causes the subsequent operations to be executed by automatic control. When the control program is started, the control unit 17 executes processing shown as a flowchart in FIG. The control unit 17 starts outputting a light projection command signal to the light projection sensor 7 and starts light projection from the light projection sensor 7 (step S1). Here, immediately after the jig 3 having the O-ring 2 inserted therein is assembled to the base 4a, the uppermost O-ring 2 (the O-ring 2a in FIG. 1 and a part of the O-ring to be taken out) is If not moved to the take-out position, the light projected from the light projecting sensor 7 is received by the light receiving sensor 8, the light receiving signal is output from the light receiving sensor 8, and the light receiving signal output from the light receiving sensor 8 is sent to the control unit 17. Entered.

  Next, the control unit 17 starts outputting the drive command signal to the collar upper and lower chucks 5 and starts the upward movement of the collar upper and lower chucks 5 (step S2), and the light receiving signal input state from the light receiving sensor 8 is started. To determine whether the uppermost O-ring 2 has been moved to the take-out position (step S3). Here, when the collar upper and lower chucks 5 are moved upward, the pole collar 11 is moved upward, and all the O-rings 2 are moved upward. As shown in FIG. When the O-ring 2 is moved to the take-out position, the light emitted from the light projecting sensor 7 is blocked by the uppermost O-ring 2 and cannot be received by the light receiving sensor 8 as described above. No signal is output.

  When the control unit 17 determines that the input of the light receiving signal from the light receiving sensor 8 has been interrupted and determines that the uppermost O-ring 2 has been moved to the take-out position (step S3: YES), the color upper and lower chucks 5 of the drive command signal Is stopped, and the upward movement of the collar upper and lower chucks 5 is stopped (step S4). Next, the control unit 17 starts outputting the drive command signal to the cutting chuck 6 and starts the movement of the cutting chuck 6 from the non-holding position to the holding position. As shown in FIG. The O-ring 2 (the O-ring 2b and the remaining O-ring in FIG. 1) arranged immediately below the O-ring 2 is held by the cutting chuck 6 (step S5).

  Next, the controller 17 outputs a suction command signal to the suction head 9 and lowers the suction head 9 from the suction standby position to the suction execution position, as shown in FIG. After adsorbing to the adsorption surface portion 9a of the adsorption head 9, as shown in FIG. 9, the uppermost O-ring 2 raises the adsorption head 9 adsorbed to the adsorption surface portion 9a from the adsorption execution position to the adsorption standby position (step) S6). Next, the control unit 17 stops the output of the drive command signal to the cutting chuck 6 and releases the holding of the O-ring 2 by the cutting chuck 6 as shown in FIG. 10 (step S7). 6 starts to move from the holding position to the non-holding position (the cutting chuck 6 is returned to the initial position).

  Then, the control unit 17 determines, for example, whether or not the number of O-rings 2 taken out has reached a preset number or whether or not the cutting chuck 6 is in contact with the O-ring 2. It is determined whether or not the O-ring 2 to be taken out remains in the jig 3 (step S8). For example, the control unit 17 determines that the number of the extracted O-rings 2 has not reached the preset number, or determines that the cutting chuck 6 is in contact with the O-ring 2, If it is determined that the O-ring 2 remains in the jig 3 (S8: YES), the process returns to the above-described step S2, and the processes of the above-described steps S2 to S8 are repeatedly executed, as shown in FIG. Remove the O-ring 2 (O-ring 2b in FIG. 1).

  On the other hand, the control unit 17 determines, for example, that the number of O-rings 2 that have been taken out has reached a preset number, or that the cutting chuck 6 has not touched the O-ring 2, If the O-ring 2 is determined not to remain in the jig 3 (S8: NO), the output of the projection command signal to the projection sensor 7 is stopped and the projection from the projection sensor 7 is stopped (step S9) The above-described series of processing ends.

  In addition, after adsorb | sucking O-ring 2 to the adsorption | suction surface part 9a of the adsorption | suction head 9 by vacuum adsorption as mentioned above, the control part 17 adsorb | sucks a conveyance command signal in parallel with performing step S7 and S8. By outputting to the head transport mechanism 16, as shown in FIG. 12, the suction head 9 is moved from the suction standby position to the suction breakdown standby position, and the suction breakdown command signal is output to the suction head 9 to perform suction. The O-ring 2 is naturally dropped from the suction surface portion 9a, the O-ring 2 is fitted into the concave portion 19 of the work 18 and assembled to the work 18, and the suction head 9 is moved from the suction failure standby position to the suction standby position (returned). ).

  As described above, according to the present embodiment, the O-ring 2 and the jig 3 that have been subjected to the cleaning process are assembled to the base 4a, and the collar upper and lower chucks 5 are moved upward so that the uppermost position can be obtained. While the O-ring 2 is being moved to the take-out position, the uppermost O-ring 2 is moved to the take-out position so as not to touch other members, and the pick-up target O-ring moved to the take-out position is moved by the suction head 9. Since the O-ring 2 and the jig 3 that have been cleaned are assembled to the base 4a, the O-ring 2 can be moved to the other by simply moving the pole collar 11 that has been cleaned. The O-ring 2 that has been subjected to the cleaning process can be taken out without foreign matter adhering to it, without touching the member.

  Further, after the uppermost O-ring 2 to be taken out is moved to the take-out position, the remaining O-ring 2 except the uppermost O-ring 2 is held by the cutting chuck 6 and the uppermost O-ring 2 is removed. 2 is taken out by the suction head 9, for example, it is possible to prevent the O-ring 2 immediately below from being taken out together with the O-ring 2 at the uppermost position due to, for example, surface tension acting. Only the ring 2 can be reliably removed.

The present invention is not limited to the above-described embodiment, and can be modified or expanded as follows.
Although the O-ring 2 is taken out in the vertical direction, the O-ring 2 may be taken out in the horizontal direction.

Although the shaft member has a linear shape, the shaft member may have an “L” shape or a “U” shape due to circumstances such as equipment restrictions.
A pole collar 11 that moves in the axial direction of the pole 10 is arranged as a movable member, and the O-ring 2 is moved by moving the pole collar 11, but for example, an annular bag in the circumferential direction of the pole 10 is used. It is good also as a structure which arrange | positions a body (balloon), introduce | transduces gas into the cyclic | annular bag body, and expands the said bag body, and moves the O-ring 2. FIG.

For example, by using a robot, the O-ring 2 and the jig 3 may be assembled to the base 4a by automatic control.
As a method for cleaning the O-ring 2, as shown in FIG. 13, a pole 24 having a flow path 23 through which the cleaning liquid flows is adopted, and the O-ring 2 and the jig 3 are cleaned by flowing the cleaning liquid through the flow path 23. You may do it.

  As a method for transporting the O-ring 2 and the jig 3, as shown in FIG. 14, a cassette 25 integrated with the pole 10 is adopted, and after the jig 3 is assembled to the base 4 a together with the cassette 25, the cassette 25 May be disassembled and removed.

  The shape of the pole may be as shown in FIG. That is, as shown in FIG. 15A, the main pole 26 and a plurality of (four in FIG. 15A) sub-poles 27 may be combined. Further, as shown in FIG. 15B, a plurality of (eight in FIG. 15B) slits (notches) 29 extending in the axial direction are formed on the outer peripheral surface of the pole 28. Also good. According to such a configuration, the contact area with the O-ring 2 can be reduced, and the resistance with the O-ring 2 can be further reduced.

  The shape of the cutting chuck may be as shown in FIG. That is, as shown in FIG. 16A, a cutting chuck 30 in which the contact surface portion 30a in contact with the O-ring 2 is a curved surface may be used.
