Description

  The present invention is, for example, an operation force transmission mechanism connected to an end of an inner wire in a remote operation mechanism using a release wire that causes a second seat of an automobile to lie down or stand up by remote operation from the position of a back door. For pulling out a connecting ring-shaped portion at the distal end of the connecting tool from the opening end of a holding cylinder in which the connecting tool is fixed at a predetermined position and slidably mounted in the axial direction. This relates to the jig.

  In general, when manufacturing a vehicle equipped with a remote control mechanism using a release wire that allows a second seat to be laid down or raised by remote control from the position of the back door, the outer wire of the release wire must be A holding cylinder, which is connected to the tube and is slidably mounted in the axial direction in the axial direction, is assembled to the lower surface of the seat. A work process is employed in which an operating force transmission mechanism connected to a remote control lever is connected to a connecting ring-shaped portion of a connecting device built in a holding cylinder.

  However, in the body assembly line, if the connecting ring-shaped portion at the tip of the connecting tool is retracted deeper than the opening end of the holding cylinder, the operating force transmission mechanism cannot be connected to the ring-shaped portion. Therefore, the holding cylinder is provided with a clip that engages with the connecting instrument to position (detent) the connecting instrument, and the connecting ring-shaped portion at the tip of the connecting instrument is exposed from the opening end of the holding cylinder. In this state, the clip is inserted into a slit formed in the cylindrical wall portion of the holding cylinder, and is configured to be engaged with the connecting device.

  However, if the clip comes off before moving to the body assembly line due to contact with other objects, or if the clip is forgotten to be hooked, the connecting ring-shaped part at the tip of the connecting tool will It will be sent to the body assembly line in a state of being retracted from the open end.

  Therefore, in the inspection process preceding the body assembly line, if the inspector inspects the holding cylinder assembled on the lower surface of the seat, and there is a holding cylinder in which the ring-shaped part at the tip of the connecting device is not exposed, the holding cylinder is After disassembling, the connecting device is pulled out, and the ring-shaped part is exposed and clipped to reset. This re-setting is a very troublesome operation involving disassembly and assembly of the holding cylinder, and requires a considerable amount of time.

  In addition, even when the clip is completely fastened as expected, when the holding cylinder is assembled to the lower surface of the seat in the seat assembly line, the connecting device built in the holding cylinder holds the ring-shaped part at the tip of the connecting device with the clip. If it is positioned (detentive) so that it is exposed from the open end of the cylinder, the length of the inner wire attached to the seat will be shortened and play will be reduced, making it difficult to assemble the seat underside. In addition, there is a problem that work efficiency is poor.

  In view of the above situation, the present invention provides a holding cylinder when the connecting ring-shaped portion of the connecting device for the operating force transmission mechanism connected to the end of the inner wire is retracted deeper than the opening end of the holding cylinder. Thus, the present invention provides a jig for pulling out the connecting device at the end of the inner wire, which can pull out the connecting device from the opening end of the holding cylinder to the state where the ring-shaped portion is exposed without disassembling.

  In order to achieve the above object, technical means taken by the present invention are as follows. That is, the inner wire end connecting device pull-out jig according to the invention of claim 1 is configured such that the operating force transmission mechanism connecting device connected to the end portion of the inner wire is fixed at a predetermined position, and A jig for pulling out the connecting ring-shaped portion at the tip of the connecting device from the open end of the holding cylinder in which the connecting device is slidably mounted in the axial direction, and engages with the ring-shaped portion. Consists of a first operating tool in which a claw that can be opened and closed is slidably held in the axial direction, a second operating tool that pulls the claw, and a release wire that connects the first and second operating tools. It is characterized in that it is.

  Specifically, the connecting device for operating force transmission mechanism connected to the end portion of the inner wire is fixed at a predetermined position like the connecting device drawing jig for connecting the end portion of the inner wire according to the invention of claim 2. And a jig for pulling out the connecting ring-shaped portion at the distal end of the connecting tool from the open end of the holding cylinder in which the connecting tool is slidably mounted in the axial direction. A first operating tool in which a claw that can be opened and closed that engages with the portion is held slidably in the axial direction, a second operating tool that pulls the claw, and the first and second operating tools are connected to each other. The claw is engaged with the taper tip tapered surface part inclined from the outer periphery of the shaft body in which the connection part of the release wire is formed at the base end, and the ring-shaped part from the inside. Possible annular groove and tip tape A shape that forms a reverse tapered surface part that is inclined in the opposite direction to the surface part, and is divided into a plurality of circumferential directions by a notch formed from the tip of the shaft body to a position closer to the shaft end side than the reverse tapered surface part. And the first operating tool is mounted on the opening end of the holding cylinder so that a tip opening can be fitted on the opening, and the cylindrical main body is slidably mounted in the axial direction and is attached to the claw. A cylindrical claw presser slidably fitted in the axial direction, a compression spring that urges the claw to protrude from the distal end opening of the cylindrical body, and an axial core on the cylindrical body. It is slidably fitted in the direction and is connected to the claw presser by a slide guide that passes through a long hole in the axial direction formed in the cylindrical body, and is integrated with the claw presser within the range of the long hole. The holder is slidable and the holder is The inner peripheral surface of the claw presser presses the reverse tapered surface portion by sliding operation toward the front end side with respect to the main body, and the claw is configured to reduce the diameter against an elastic restoring force. It is characterized by that.

  Since the jig for pulling out the connecting device at the end of the inner wire according to the present invention has the above-described configuration, the connecting ring-shaped portion of the connecting device for the operating force transmission mechanism connected to the end of the inner wire is the opening of the holding cylinder. When retracted deeper than the end, the claw of the first operating tool is inserted into the holding cylinder from the open end without disassembling the holding cylinder, and is engaged with the ring-shaped portion of the connecting device located in the holding cylinder. In this state, the connecting device can be pulled out from the open end of the holding cylinder to the state where the ring-shaped portion is exposed by pulling the claw with the second operation tool. In this state, the claw can be opened and closed to disengage the ring-shaped portion from the claw.

  In particular, according to the configuration of the invention according to claim 2, the claw of the first operating tool is tapered at the outer peripheral surface of the shaft body in which the connecting portion of the release wire is formed at the original end. A taper surface portion, an annular groove portion that can be engaged with the ring-shaped portion from the inside, and a reverse taper surface portion that is inclined in a direction opposite to the tip taper surface portion, and a shaft body from the tip of the shaft body to the reverse taper surface portion. It has a shape divided into a plurality of circumferential directions by notches formed over the position on the former end side, and slides integrally with a cylindrical nail presser that is slidably fitted to the nail in the axial direction. By sliding the possible holder toward the distal end side with respect to the cylindrical body, the inner peripheral surface of the claw pressing member presses the reverse tapered surface portion, and the claw is reduced in diameter against an elastic restoring force. Because of this configuration, the sliding operation of the holder relative to the cylindrical body Makes it possible to perform engagement and disengagement of the annular section due to the opening and closing of the nail, it is easy withdrawing operation of the coupling instrument.

  That is, since the claw is formed with a tapered end portion, when the claw is inserted from the opening end of the holding cylinder and the annular groove portion of the claw is engaged with the ring-shaped portion of the connecting device located in the holding cylinder, The tapered surface portion serves as a guide for inserting the nail into the ring-shaped portion, and the nail can be easily inserted.

  Also, if the spring force of the compression spring that urges the nail to protrude from the tip opening of the cylindrical body is strong, the tip taper surface part is pressed by the ring-shaped part as the nail is inserted, and the nail is It is possible to reduce the diameter against the elastic restoring force and engage the annular groove of the claw with the ring-shaped part, but the stronger the spring force of the compression spring for claw restoration, the more A large force is required for the pulling operation.

  In this regard, according to the above-described configuration, the inner peripheral surface of the claw presser that slides integrally with the holder is formed by forming a reverse tapered surface portion on the claw and sliding the holder toward the tip side with respect to the cylindrical body. Presses the reverse taper surface portion and the claw contracts against the elastic restoring force, so that the annular groove portion of the claw can be engaged with the ring-shaped portion even if the spring force of the compression spring is weak. . For these reasons, the pull-out operation of the connecting device is facilitated.

  Further, as described above, since the connecting device retracted into the back of the holding cylinder can be easily pulled out from the opening end of the holding cylinder, for example, when assembling the holding cylinder on the lower surface of the sheet in the sheet assembly line, By assembling the holding cylinder without attaching the positioning (detentive) clip, it is possible to increase the play of the inner wire attached to the seat and improve the assembling work efficiency on the lower surface of the seat.

  FIG. 1 shows an example of a jig for pulling out a connecting tool at an end of an inner wire according to the present invention. In FIG. 1, reference numeral 1 denotes a holding cylinder fixed at a predetermined position (for example, a lower surface of a second seat of an automobile), and includes a cylinder main body 1a and a lid body 1b fitted to one end thereof. 2 is a release wire, the outer tube 2a is connected to the lid 1b of the holding cylinder 1, and the end of the inner wire 2b (the cylindrical metal piece is crimped to form a large diameter portion) The holding cylinder 1 is connected to a connecting device 3 for an operating force transmission mechanism that is slidably mounted in the axial direction.

  The connecting device 3 has a connecting ring-shaped portion 3a at one end, and a radial slit 3b in which the end (large diameter portion) of the inner wire 2b is locked is formed in the disk-shaped portion at the other end. ing. 4 is a clip made of steel or synthetic resin that engages with the connecting device 3 to position (detent) the connecting device 3. A slit 1c for reducing the diameter when the lid 1b is fitted and a slit 1d for inserting the clip 4 are formed in the cylinder wall portion of the cylinder main body 1a in the holding cylinder 1.

  The jig for pulling out the connecting device at the end of the inner wire includes a first operation tool 6 in which a claw 5 that can be opened and closed that engages with the ring-shaped portion 3a is held slidably in the axial direction, and the claw 5 It comprises a second operating tool 7 for pulling operation and a release wire 8 for connecting the first and second operating tools 6 and 7. 8a is an outer tube, 8b is an inner wire.

  2 to 6 show the detailed structure and operation of the first operation tool 6. The claw 5 is engaged from the inner side with a tapered end tapered surface portion a on the outer peripheral surface of the shaft body in which the connecting portion of the inner wire 8b in the release wire 8 is formed at the original end, and the ring-shaped portion 3a. An annular groove portion b that can be joined and a reverse taper surface portion c that is inclined in a direction opposite to the tip taper surface portion a are formed in this order from the tip, and the shaft body from the tip of the shaft body to the end side of the shaft body from the reverse taper surface portion c. The shape is divided into four in the circumferential direction by a cross-shaped notch 9 formed over the position.

  The first operating tool 6 is provided with a cylindrical main body 10 in which a tip opening 10 a can be fitted to the opening end of the holding cylinder 1, and is slidably mounted in the axial direction in the cylindrical main body 10 and is attached to the claw 5. On the other hand, a cylindrical claw presser 11 fitted so as to be slidable in the axial direction, a spring receiver 12 applied to the base end of the claw 5, and a base end opening of the cylindrical body 10 are screwed and fixed. A compression spring 14 that is interposed between the spring receiver 13 and biases the claw 5 so as to protrude from the distal end opening 10a of the cylindrical main body 10, and is free to slide in the axial direction on the cylindrical main body 10. And is connected to the claw retainer 11 by a slide guide 15 and two connecting screws 16 passing through a long hole 10b in the axial direction formed in the cylindrical main body 10, and the long hole 10b. So as to slide integrally with the claw presser 11 within the range of And a made a holder 17.

  Then, by sliding the holder 17 toward the distal end side with respect to the cylindrical main body 10, the inner peripheral surface of the claw presser 11 presses the reverse tapered surface portion c, and the claw 5 becomes elastic restoring force. It is configured so as to be reduced in diameter.

  If the connecting instrument drawing tool at the end of the inner wire having the above configuration is used, the connecting ring-shaped portion 3a of the connecting instrument 3 for the operating force transmission mechanism connected to the end of the inner wire 2b When retracted deeper than the opening end, the connecting device 3 can be pulled out from the opening end of the holding cylinder 1 to the state where the ring-shaped portion 3a is exposed without disassembling the holding cylinder 1.

  In particular, the claw 5 of the first operation tool 6 has a tapered end tapered surface portion a inclined on the outer peripheral surface of the shaft body in which the connecting portion of the inner wire 8b in the release wire 8 is formed at the original end, An annular groove b that can be engaged with the ring-shaped portion 3a from the inside and a reverse tapered surface portion c that is inclined in a direction opposite to the tip tapered surface portion a are formed, and a shaft body is formed from the tip of the shaft body to the reverse tapered surface portion c. A cylindrical nail presser having a shape divided into four in the circumferential direction by a cross-shaped notch 9 formed over the position on the former end side, and is slidably fitted to the nail 5 in the axial direction. When the holder 17 slidable integrally with the cylindrical body 10 is slid to the distal end side with respect to the cylindrical main body 10, the inner peripheral surface of the claw retainer 11 presses the reverse tapered surface portion c, and the claw 5 It is configured to shrink against the elastic restoring force. Since, by the sliding operation with respect to the cylindrical main body 10 of the holder 17, it is possible to perform engagement and disengagement between the ring-shaped portion 3a by opening and closing of the claw 5, it is easy withdrawing operation of the connecting device 3.

  That is, since the claw 5 is formed with the tip tapered surface portion a, the claw 5 is inserted into the ring-shaped portion 3a of the connecting device 3 which is inserted into the holding cylinder 1 by inserting the claw 5 from the opening end of the holding cylinder 1. When engaging the groove b, the tip tapered surface portion a serves as a guide for inserting the claw 5 into the ring-shaped portion 3a, and the claw 5 can be easily inserted.

  Further, if the spring force of the compression spring 14 that urges the claw 5 to protrude from the front end opening 10a of the cylindrical body 10 is strong, the front end tapered surface portion of the ring-shaped portion 3a is accompanied by the insertion of the claw 5. It is possible to press a to reduce the diameter of the claw 5 against the elastic restoring force and to engage the annular groove b of the claw 5 with the ring-shaped portion 3a. The stronger the spring force, the greater the force required to pull the claw 5 by the second operating tool 7.

  However, according to the above configuration, the claw presser that slides integrally with the holder 17 is formed by forming the reverse tapered surface portion c on the claw 5 and sliding the holder 17 toward the distal end side with respect to the cylindrical body 10. Since the inner peripheral surface of 11 presses the reverse taper surface portion c and the claw 5 contracts against the elastic restoring force, the annular groove b of the claw 5 is formed even if the spring force of the compression spring 14 is weak. It can be engaged with the ring-shaped part 3a. For these reasons, the pulling-out operation of the connecting device 3 is facilitated.

  Further, as described above, since the connecting device 3 retracted into the back of the holding cylinder 1 can be easily pulled out from the opening end of the holding cylinder 1, for example, when the holding cylinder 1 is assembled to the lower surface of the sheet in the sheet assembly line. By assembling the holding cylinder 1 without attaching the positioning (detentive) clip 4 of the connecting device 3, it is possible to increase the play of the inner wire to be attached to the seat and to improve the assembling work efficiency on the lower surface of the seat. .
