Description

  The present invention relates to a clip attachment jig for attaching a clip to an attachment portion in an attachment target.

  For example, in assembly plants such as automobiles, resin clips are used instead of bolts and nuts when assembling exterior parts to a vehicle body. Specifically, a plurality of bolts provided in the vehicle body are passed through a plurality of through holes provided in the exterior part, and a clip is attached to each bolt protruding from each through hole, thereby providing an exterior part to the vehicle body. Is being assembled. The worker has the same number of clips as the number of bolts and through holes formed, and attaches the clips to each bolt one by one.

  As a clip used for assembling an automobile or the like, for example, there is a panel material mounting clip disclosed in Patent Document 1. Although not related to the assembly of an automobile or the like, for example, Patent Document 2 discloses a repetitive-type clip treatment tool that allows a plurality of clips to be used repeatedly.

Japanese Utility Model Publication No. 1-78710 JP 2009-291535 A

  By the way, when an operator directly holds a required number of clips without using a jig and attaches these clips to bolts one by one, there is a loss of time to move the clips from the left hand to the right hand. There is also a possibility that a loss of time for picking up a clip will occur. On the other hand, the structure of the clip treatment tool disclosed in Patent Document 2 or the like is a complicated structure including an operation wire, a moving mechanism, and the like, and cannot be applied as it is to a clip used for assembling industrial products.

  The present invention has been made in view of such a background, and has been obtained in an attempt to provide a clip attachment jig capable of sequentially attaching a plurality of clips to an attachment portion in a short time with an extremely simple structure. .

One aspect of the present invention is a clip attachment jig used for attaching a clip having a small diameter portion and a large diameter portion having an outer diameter larger than the small diameter portion to an attachment portion provided in the attachment target. ,
An accommodating cylinder for accommodating the plurality of clips in a row, having an open end at the front end and a closed end at the rear end;
An urging member that is disposed in the receiving cylinder adjacent to the closed end and urges the clip toward the distal end;
An elastically deformable stopper provided to project toward the inner peripheral side at the opening end,
An elastically deformable lock lever that protrudes toward the inner peripheral side on the rear end side from the position of the opening end where the stopper is provided, and
The stopper includes a natural state in which a distal end side clip accommodated at the most distal end side in the accommodation cylinder is prevented from being pushed out by the biasing member and coming out of the opening end portion, and the distal end side clip is It is possible to form a deformed state that is elastically deformed to the outer peripheral side when it is engaged with the attached portion and pushed by the biasing member and pulled out from the opening end.
The lock lever is adjacent to the rear end side of the front end side clip and the natural state that prevents the front end side clip from being pushed into the rear end side when the front end side clip engages with the mounted portion. The clip mounting jig is capable of forming a deformed state in which the adjacent clip is elastically deformed toward the outer peripheral side when the adjacent clip is pushed out by the biasing member.

The clip mounting jig efficiently attaches a clip having a small diameter portion and a large diameter portion to a mounting portion to be mounted by a simple structure using a housing cylinder, a biasing member, a stopper, and a lock lever. It is something that can be done. Then, by using the stopper and the lock lever, the clip is prevented from coming out to the front end side and pushed into the rear end side, so that the clips can be supplied one by one to the attached portion.
In attaching the clip to the attachment portion to be attached using the clip attachment jig, the operator pushes the necessary number of clips into the accommodating cylinder against the urging force of the urging member. At this time, when the lock lever prevents the clip from being pushed, the lock lever can be appropriately deformed.

In the state where the clip is housed in the housing cylinder, the leading end side clip housed in the most distal end side in the housing cylinder is pushed by the urging member by the stopper in the natural state, and the outside from the opening end to the outside. Getting out is prevented.
Next, when the operator makes the clip attachment jig face the attachment portion and engages the tip side clip with the attachment portion, the tip side clip is pushed to the rear end side by the lock lever in a natural state. Is blocked.

  When the operator moves the clip mounting jig away from the mounted portion after the distal end side clip is engaged with the mounted portion, the stopper is pushed by the distal end side clip and is temporarily elastically deformed to the outer peripheral side. The leading end side clip is pushed to the leading end side by the urging member, and is pulled out from the opening end of the housing cylinder. Further, when the distal end side clip is pulled out, the adjacent clip adjacent to the rear end side of the distal end side clip is pushed out to the distal end side by receiving the urging force of the urging member. At this time, the lock lever is pushed by the adjacent clip, and is temporarily elastically deformed to the outer peripheral side to be in a deformed state. In this way, the tip side clip is attached to the attached portion, and the adjacent clip becomes the next tip side clip.

Thereafter, in the same manner, the clip attachment jig is opposed to each attached portion, and the front end side clip is attached sequentially to each attached portion.
As described above, by using the clip mounting jig, a necessary number of clips corresponding to the number of mounted portions to be mounted can be easily and sequentially mounted on each mounted portion. Therefore, it becomes unnecessary to change the clip, which is necessary when the operator directly holds the clip, and the clip is not accidentally dropped. Thereby, the time which attaches a some clip to a some to-be-attached part can be shortened. Further, the clip mounting jig can be realized by an extremely simple structure using the functions of the biasing member, the stopper, and the lock lever.

Therefore, according to the clip mounting jig, a plurality of clips can be sequentially mounted on the mounted portion in a short time with a very simple structure.
The terms “front end side clip” and “adjacent clip” are terms used for convenience to indicate the position of the clip, and the front end side clip and the adjacent clip are the same as other clips.

  As shown in FIGS. 1 and 3, the stopper 4 is formed as a portion left between a pair of slits 24 provided from the opening end 22 of the housing cylinder 2 toward the rear end. The stopper 4 is connected in a cantilevered manner along the axial direction L so that the rear end portion is connected to the housing cylinder 2 and can be bent toward the outer periphery starting from the rear end portion. A protruding portion 41 that protrudes toward the inner peripheral side of the receiving hole 21 of the receiving cylinder 2 and can contact the clip 8 is provided at the tip of the stopper 4. The distal end side clip 8 </ b> A accommodated in the accommodation hole 21 is in contact with the protruding portion 41 of each stopper 4 in the natural state 401, and is prevented from coming out from the open end 22.

  As shown in FIGS. 2 and 3, the lock lever 5 has a rear end portion attached to the housing cylinder 2, and is a piece along the axial direction L so that the lock lever 5 can be bent outward from the rear end portion. It is provided in the holding state. A protruding portion 51 that protrudes toward the inner peripheral side of the receiving hole 21 of the receiving cylinder 2 and can contact the clip 8 is provided at the distal end portion of the lock lever 5. An arrangement hole 25 is formed in the distal end portion of the housing cylinder 2 so that the protruding portion 51 of the lock lever 5 is disposed from the outer peripheral side and protrudes to the inner peripheral side of the housing hole 21. The arrangement hole 25 can be configured by a through hole or a notch formed on the rear end side from the opening end 22. The front end side clip 8 </ b> A accommodated in the accommodation hole 21 abuts against the protruding portion 51 of each lock lever 5 in the natural state 501 and is prevented from being pushed into the rear end side of the accommodation hole 21.

The front end surface 511 of the protruding portion 51 of each lock lever 5 is formed as a surface substantially parallel to the radial direction in order to prevent movement of the front end side clip 8A toward the rear end side. The rear end surface 512 of the protruding portion 51 of each lock lever 5 is formed as a tapered surface that changes toward the inner peripheral side toward the front end side in order to allow movement of the adjacent clip 8B toward the front end side.
The lock lever 5 is configured by a separate member attached to the outer periphery of the housing cylinder 2. The housing cylinder 2 including the stopper 4 can be made of a resin material, and the lock lever 5 can be made of a metal material.

  As shown in FIGS. 1 and 2, the urging member 3 is constituted by a compression coil spring that generates an elastic restoring force when compressed. The pushing portion 31 for pushing the clip 8 in the accommodation hole 21 toward the tip side can be provided at the tip portion of the urging member 3. In the accommodation hole 21 of the accommodation cylinder 2, the same number as the number of bolts 711 and attachment holes 721 used when the automobile exterior part 72 is attached to the vehicle body 71 in the state where the urging member 3 is most compressed. The clip 8 can be accommodated.

  The deflection amount and the urging force of the urging member 3 and the length of the housing cylinder 2 are as follows. As shown in FIGS. 1 and 2, a predetermined number of clips in the housing hole 21 when the urging member 3 is most compressed. 8 is entered, and as shown in FIG. 8, even when the number of the clips 8 accommodated in the accommodation hole 21 becomes one, it is determined so as to satisfy a condition capable of applying an urging force to the clip 8.

It determines so that the conditions which can be extruded to the most tip side of 21 are satisfy | filled.

  In order to allow the clip mounting jig 1 to contain only a predetermined number of clips 8 or less, for example, as shown in FIG. An abutting member 231 that can abut on 31 can be provided toward the tip side. When a predetermined number of clips 8 are inserted into the receiving hole 21 of the clip mounting jig 1 and the abutting member 231 comes into contact with the push-out portion 31, the urging member 3 is prevented from being compressed and attached. The force member 3 can form the most compressed state. That is, the state in which the urging member 3 is compressed most can be formed when the abutting member 231 abuts on the pushing portion 31.

Next, the order of attaching the clip 8 to the bolt 711 of the vehicle body 71 inserted into the attachment hole 721 of the automobile exterior part 72 using the clip attachment jig 1 will be described, and the operation of the clip attachment jig 1 will be described. The effect will be described.
First, the worker places the automobile exterior part 72 in the vehicle body 71 in a state where the plurality of bolts 711 in the vehicle body 71 are inserted into the plurality of mounting holes 721 in the automobile exterior part 72. Further, the operator sequentially pushes the predetermined number of clips 8 necessary for mounting the automobile exterior part 72 into the accommodation hole 21 of the accommodation cylinder 2 against the urging force of the urging member 3. At this time, the operator can forcibly elastically deform the lock levers 5 toward the outer peripheral side of the housing cylinder 2 so that the lock levers 5 do not hinder the pushing of the clips 8. Moreover, each clip 8 is accommodated in the accommodation hole 21 in the state which positions the large diameter part 82 in the front end side.

  As shown in FIG. 1, in a state where a predetermined number of clips 8 are accommodated in the accommodation hole 21, the plurality of clips 8 are pushed to the distal end side by the urging force of the urging member 3, and the inside of the accommodation hole 21. The distal end side clip 8 </ b> A accommodated at the most distal end side contacts the protruding portion 41 of each stopper 4. As a result, the plurality of clips 8 are prevented from being pushed out by the biasing member 3 and coming out of the opening end 22 to the outside.

Next, as shown in the figure, the operator makes the clip mounting jig 1 in which a predetermined number of clips 8 are accommodated face the first bolt 711. An operator holding the clip attachment jig 1 brings the clip attachment jig 1 closer to the vehicle body 71 and the automobile exterior part 72 so that the bolt 711 is inserted into the engagement hole 83 of the distal end side clip 8A.
Then, as shown in FIG. 5, when the bolt 711 is inserted into the engagement hole 83 of the distal end side clip 8A, the large size of the distal end side clip 8A is placed on the distal end surface 511 of the protrusion 51 of the lock lever 5 in the natural state 501. When the diameter portion 82 abuts, the front end side clip 8A is prevented from being pushed to the rear end side.

  Next, after the bolt 711 is inserted into the engagement hole 83 of the distal end side clip 8A, the worker moves the clip mounting jig 1 away from the vehicle body 71 and the automobile exterior part 72 as shown in FIG. At this time, the protrusion 41 of each stopper 4 is pushed by the large-diameter portion 82 of the tip side clip 8 </ b> A that has received the urging force of the urging member 3. And the protrusion part 41 of each stopper 4 retracts | saves to an outer peripheral side temporarily, and each stopper 4 will be in the deformation state 402 elastically deformed to the outer peripheral side. In this way, the distal end side clip 8 </ b> A pushed to the distal end side by the urging member 3 is extracted from the opening end 22 of the housing cylinder 2 to the outside and attached to the bolt 711.

  Further, when the distal end side clip 8A is pulled out of the receiving hole 21, as shown in FIG. 7, the adjacent clip 8B adjacent to the rear end side of the distal end side clip 8A is received by the urging force of the urging member 3. Is pushed to the tip side. At this time, the rear end surface 512 of the protrusion 51 of each lock lever 5 is pushed by the large diameter portion 82 of the adjacent clip 8B. And the protrusion part 51 of each lock lever 5 retracts | saves to an outer peripheral side temporarily, and each lock lever 5 will be in the deformation state 502 elastically deformed to the outer peripheral side. In this way, the adjacent clip 8B is pushed out to the front end side until it abuts against the protruding portion 41 of each stopper 4, and the adjacent clip 8B becomes the next front end side clip 8A.

  Next, the operator attaches the clip attaching jig 1 to the second bolt 711 and attaches the clip 8 to the second bolt 711 in the same manner as described above. Thereafter, in the same manner, all the clips 8 accommodated in the clip mounting jig 1 are sequentially attached to the respective bolts 711.

  In this way, by using the clip mounting jig 1, a necessary number of clips 8 corresponding to the number of bolts 711 formed can be easily and sequentially attached to each bolt 711. Therefore, it becomes unnecessary to change the clip 8, which is necessary when the operator directly holds the clip 8, and the clip 8 is not accidentally dropped. Thereby, the time which attaches the some clip 8 to the some volt | bolt 711 can be shortened. Further, the clip mounting jig 1 can be realized by an extremely simple structure using the functions of the biasing member 3, the stopper 4 and the lock lever 5.

  Further, when the automobile exterior part 72 is attached to the vehicle body 71, the clip attachment jig 1 accommodates the number of clips 8 necessary for attaching the automobile exterior part 72. The operator then attaches the clips 8 until all the clips 8 in the clip attachment jig 1 are extracted to the outside and the inside of the clip attachment jig 1 is empty. Accordingly, when the plurality of clips 8 are accommodated in the clip attachment jig 1, if the number of the clips 8 is confirmed, the number of the attached clips 8 is confirmed when the clips 8 are attached to the bolt 711. There is no need. Therefore, the clip 8 can be quickly and reliably attached to all the bolts 711, and forgetting to attach the clip 8 to the bolt 711 can be eliminated.

  Therefore, according to the clip attachment jig 1, a predetermined number of clips 8 can be sequentially attached to the bolts 711 in a short time with an extremely simple structure.
