Description

[Technical field]

[0001] The present invention relates to a door hinge mounting device for mounting a door hinge to a vehicle body in a vehicle production line. [Background technology]

[0002] In a vehicle manufacturing line, when a door is attached to a vehicle body, for example, the door hinge is attached to the vehicle body, and then the door is attached to the door hinge. When attaching the door hinge to the vehicle body, for example, a door hinge attachment jig is used, and an operator inserts a reference pin of the door hinge attachment jig so as to follow a reference hole provided on the vehicle body, thereby dealing with an assembly dimensional error of the vehicle body. For example, Patent Document 1 describes a door hinge attachment jig that uses a spring to absorb assembly dimensional errors of the vehicle body, allowing an operator to easily align the position. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2005-47453 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, there was a problem that it was difficult for an operator to insert the reference pin of the door hinge mounting jig by following the reference hole of the vehicle body, since it required skilled techniques. Also, when a floating mechanism using a spring or the like is provided in the door hinge mounting jig as in Patent Document 1, when an industrial robot is used to move the door hinge mounting jig and insert the reference pin into the reference hole of the vehicle body, the door hinge mounting jig shakes due to inertia force, and the reference hole is deformed instead of the reference pin being inserted into the reference hole.

[0005] The present invention has been made in light of the above problems, and has an object to provide a door hinge mounting device that can easily and appropriately mount a door hinge to a vehicle body. [Means for solving the problem]

[0006] The door hinge mounting device of the present invention is used to mount a door hinge to a vehicle body, and comprises a jig part that supports the door hinge in a removably manner, an arrangement part that is arranged relative to a jig part moving means that moves the jig part, a floating part that supports the jig part and is arranged so that it can move relative to the arrangement part, and a locking means that fixes the floating part to prevent it from moving relative to the arrangement part or releases the fixation to allow it to move. Effect of the Invention

[0007] According to the present invention, the floating part is fixed to the installation part by the locking means, or released to allow movement, so that, for example, when the door hinge is moved close to the vehicle body, the jig part is fixed to suppress shaking, and when the reference pin is inserted into the reference hole, the floating part is released to allow movement relative to the installation part, thereby absorbing assembly dimensional errors of the vehicle body. Therefore, the reference pin can be easily and appropriately inserted into the reference hole. [Brief description of the drawings]

[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0010] (One embodiment) FIG. 1 shows the configuration of a door hinge mounting device 1 according to an embodiment of the present invention. FIG. 2 shows a part of the cross-sectional configuration taken along line II shown in FIG. 1. FIG. 3 shows a part of the cross-sectional configuration taken along line II-II shown in FIG. 2. FIGS. 4 and 5 show a part of the cross-sectional configuration taken along line III-III shown in FIG. 2. This door hinge mounting device 1 is for mounting a door hinge M to a vehicle body in a vehicle production line. The door hinge mounting device 1 is disposed, for example, to the side of the vehicle production line, and the vehicle body is transported through the production line by a conveyor or the like and stops beside the door hinge mounting device 1.

[0011] The door hinge mounting device 1 includes, for example, a jig unit 10 that removably supports the door hinge M, a jig unit moving means (not shown) such as an industrial robot that moves the jig unit 10, an installation unit 20 that is arranged relative to the jig unit moving means, a floating unit 30 that supports the jig unit 10 and is arranged movably relative to the installation unit 20, and a locking means 40 that fixes the floating unit 30 so that it does not move relative to the installation unit 20 or releases the fixation to make it movable. Note that in Fig. 1, the detailed configuration of the jig unit 11 is omitted, and in Figs. 2 to 5, the jig unit 11 is omitted, and the configurations of the installation unit 20, the floating unit 30, and the locking means 40, or the installation unit 20 and the floating unit 30 are extracted and shown.

[0012] The jig part 10 is for supporting the door hinge M and attaching it to the vehicle body, and has, for example, a door hinge support part 11 that detachably supports the door hinge M, and a reference pin 12 that is inserted into a reference hole in the vehicle body for alignment. It is preferable that the tip of the reference pin 12 is inclined so that the width narrows toward the tip, for example.

[0013] The installation section 20 has, for example, an attachment section 21 that is attached to the arm of an industrial robot serving as the moving means, a rectangular installation plate-like section 22 on which the floating section 30 is arranged, and an installation connecting section 23 that supports the installation plate-like section 22 and connects it to the attachment section 21. The installation plate-like section 22 is provided with, for example, an installation through hole 24 that penetrates in the thickness direction. The installation through hole 24 is a hole into which a lock pin 41 of the locking means 40 described later is inserted, and it is preferable that a plurality of installation through holes (for example, two) are provided.

[0014] The floating section 30 has, for example, a frame body 31 that houses the installation plate-like section 22 therein and is movable along the surface of the installation plate-like section 22, and a jig support section 32 that is arranged on the frame body 31 and to which the jig section 10 is attached. The frame body 31 has, for example, a structure in which a pair of rectangular frame body plate-like sections 31A that are provided to sandwich the installation plate-like section 22 therebetween are connected by a plurality of rod-shaped frame body connecting members 31B. One of the frame body plate-like sections 31A of the frame body 31 has, for example, an installation hole 31C through which the installation connecting section 23 passes.

[0015] A pair of rollers 33 are disposed in the frame 31 so as to contact one side (e.g., an upper side) of the arrangement plate-like portion 22. In addition, a pair of elastic members 34 such as springs are disposed in the frame 31, for example, along a pair of sides (e.g., a pair of side sides) sandwiching one side of the arrangement plate-like portion 22. The roller 33 side end of each elastic member 34 is disposed, for example, on a pair of roller connecting members 35 that are individually connected to each roller 33 so as to be rotatable. The opposite end of each elastic member 34 is disposed, for example, on the frame 31. In the floating portion 30, for example, the roller 33 assists the movement of one side of the arrangement plate-like portion 22 in the length direction, and the elastic member 34 assists the movement of the pair of sides sandwiching one side of the arrangement plate-like portion 22 in the length direction.

[0016] The frame 31 is also provided with frame through holes 36 at positions corresponding to the arrangement through holes 24. Specifically, for example, the frame through holes 36 are provided in each of the frame plate portions 31A in correspondence with the arrangement through holes 24. It is preferable that the arrangement through holes 24 and the frame through holes 36 have approximately the same size, for example.

[0017] The locking means 40 has, for example, a lock pin 41 that penetrates the installation through-hole 24 and the frame through-hole 36 and is movable in the penetration direction (i.e., length direction), and a lock pin moving means 42 that moves the lock pin 41 in the penetration direction. That is, the locking means 40 is configured to fix the floating part 30 so that it does not move relative to the installation part 20, or to release the fixing of the floating part 30 to the installation part 20 and make it movable, by moving the lock pin 41 in the penetration direction. The locking means 40 is disposed, for example, relative to the floating part 30, specifically, the frame 31.

[0018] The lock pin 41 has, for example, a fixed portion 41A having a thickness corresponding to the arrangement through hole 24, and a release portion 41B having a thickness thinner than that of the fixed portion 41A. As a result, the locking means 40 is configured to fix the floating portion 30 so as not to move relative to the arrangement portion 20 when the fixed portion 41A is positioned corresponding to the arrangement through hole 24 (when inserted into the arrangement through hole 24; see FIG. 4), and to release the fixation when the release portion 41B is positioned corresponding to the arrangement through hole 24 (when inserted into the arrangement through hole 24; see FIG. 5), thereby allowing the floating portion 30 to move relative to the arrangement portion 20 by the gap between the release portion 41B and the arrangement through hole 24.

[0019] It is preferable that the lock pin 41 has a pair of fixing parts 41A sandwiching a release part 41B in the penetration direction, for example, so that when the release part 41B is positioned corresponding to the arrangement through hole 24, the pair of fixing parts 41A are positioned corresponding to the pair of frame body through holes 36. This is because the lock pin 41 can be stably held by the frame body 31 at the time of release.

[0020] The lock pin moving means 42 is configured by, for example, a cylinder, and has a lock pin 41 disposed at the tip of a piston rod 42A. The lock pin moving means 42 is disposed by fixing a cylinder tube 42B to the frame 31, for example.

[0021] The locking means 40 is preferably configured such that, for example, the operation is controlled by a control unit (not shown), the floating portion 30 is fixed so as not to move relative to the installation portion 20 when the door hinge M is moved to the vicinity of the vehicle body, and the fixing is released to allow the floating portion 30 to move relative to the installation portion 20 when the reference pin 12 is inserted into the reference hole. That is, the locking means 40 is preferably configured such that the floating portion 30 is fixed so as not to move relative to the installation portion 20 before the reference pin 12 is inserted into the reference hole, and the fixing is released to allow the floating portion 30 to move relative to the installation portion 20 when the reference pin 12 is inserted into the reference hole. This is because the vibration of the jig portion 10 is suppressed during the movement, and the floating portion 30 is made movable relative to the installation portion 20 when the reference pin 12 is inserted, thereby absorbing the assembly dimensional error of the vehicle body.

[0022] For example, this door hinge mounting device 1 is used as follows: First, in a vehicle production line, when a vehicle body is transported and stopped beside the door hinge mounting device 1, the door hinge mounting device 1 moves the door hinge M supported by the jig part 10 to the vicinity of the vehicle body by the jig part moving means. At that time, the locking means 40 moves the lock pin 41 so that the fixing part 41A is positioned corresponding to the installation through-hole 24, for example, and fixes the floating part 30 so as not to move relative to the installation part 20 (see FIG. 4).

[0023] Next, the jig part moving means moves the jig part 10 to insert the reference pin 12 into the reference hole of the vehicle body. At that time, the locking means 40, for example, moves the lock pin 41 so that the fixing part 41A corresponds to the frame body through hole 36 and the releasing part 41B corresponds to the installation through hole 24, thereby releasing the fixing of the floating part 30 to the installation part 20 and allowing the floating part 30 to move relative to the installation part 20 by the gap between the releasing part 41B and the installation through hole 24 (see FIG. 5). As a result, even if there is an assembly dimensional error between the reference pin 12 and the reference hole, the floating part 30 moves relative to the installation part 20 according to the inclination of the tip of the reference pin 12, and the reference pin 12 is inserted into the reference hole.

[0024] As described above, according to this embodiment, the floating part 30 is fixed to the installation part 20 by the locking means 40, or the fixed part is released to make it movable, so that, for example, when the door hinge M is moved close to the vehicle body, the jig part 10 is fixed to suppress shaking, and when the reference pin 12 is inserted into the reference hole, the fixed part is released to make the floating part 30 movable relative to the installation part 20, thereby absorbing assembly dimensional errors of the vehicle body. Therefore, the reference pin 12 can be easily and appropriately inserted into the reference hole.

[0025] (Modification) Fig. 6 shows the structure of a door hinge mounting device 100 according to a modified example of the present invention, and shows a cross-sectional structure corresponding to Fig. 3. In the above embodiment, the case where the installation section 20 is provided with the installation plate-like portion 22 and the floating section 30 is provided with the frame body 31 for movably storing the installation plate-like portion 22 has been described. However, the installation section 20 may be provided with the frame body 121 for arranging the floating section 30, and the floating section 30 may be provided with the installation plate-like portion 131 that is stored inside the frame body 121 and is movable along the frame body 121. Even with such a configuration, it functions similarly to the above embodiment and can obtain the same effects. In this modified example, the same components as those in the above embodiment are described with the same reference numerals.

[0026] The frame body 121 has a configuration similar to that of the frame body 31 of the embodiment, for example, and a pair of frame body plate-shaped parts 121A are connected by a frame body connecting member 121B, and one of the frame body plate-shaped parts 121A is provided with an arrangement hole 121C through which the jig support part 32 passes. The frame body 121 is arranged, for example, by fixing the other frame body plate-shaped part 121A to the arrangement connecting part 23. Also, in the frame body 121, as in the embodiment, for example, a roller (not shown) corresponding to the roller 33, an elastic member 122 corresponding to the elastic member 34, a roller connecting member (not shown) corresponding to the roller connecting member 35, and a frame body through hole (not shown) corresponding to the frame body through hole 36 are provided. The arrangement plate-shaped part 131 has a configuration similar to that of the arrangement plate-shaped part 22 of the embodiment, for example, and is provided with an arrangement through hole (not shown) corresponding to the arrangement through hole 24.

[0027] Although the present invention has been described above with reference to the embodiment, the present invention is not limited to the above embodiment and can be modified in various ways. For example, in the above embodiment, each component is specifically described, but the specific structure or shape of each component may be different, and the present invention may not include all of the above-mentioned components, and may include other components.
