Description

Technical Field

[0001] The present invention relates to an apparatus and method for manufacturing a composite part for an automobile in which a metal part is fixed to a mounting part.

Background Art

[0002] Among the parts for automobiles, there are composite parts formed by combining two parts. For example, as shown in FIG. 8(A), the vehicle body part 1 described in Patent Document 1 below is a composite part in which a metal side member 3 (metal part) is fixed to a side part on the back surface of a front floor 2 (mounting part) as a main panel.

[0003] In the conventional example described in Patent Document 1 for manufacturing the vehicle body part 1, with the locking claw 3a of the side member 3 inserted through the locking hole 2a of the front floor 2, as shown in FIG. 8(B), the back surface of the front floor 2 is placed downward and supported by a jig 5 of a manufacturing apparatus 4.

[0004] In the manufacturing apparatus 4, a bending pad P is provided above the locking claw 3a of the side member 3 supported by the jig 5. The bending pad P has a preliminary bending pad 6 and a main bending pad 7.

[0005] The preliminary bending pad 6 has a preliminary bending slope 6b continuous with a pad surface 6a for pressing the front floor 2 and a guide groove 6c (FIG. 8(C)) penetrating the slope 6b vertically, and is attached to a mounting post 8 via a guide rod 6d. The guide rod 6d is inserted into a coil spring 6e and slidably inserted into a guide hole 8a of the mounting post 8, and is prevented from coming off by a stopper 6f at the end of the guide rod 6d. The preliminary bending pad 6 is biased toward the vehicle body part 1 by the coil spring 6e. The main bending pad 7 is fixed to the mounting post 8 adjacent to the guide rod 6d, and the tip thereof can enter the guide groove 6c of the preliminary bending pad 6.

[0006] As shown in Figure 8(D), when the support jig 5 rises, the locking claw 3a of the side member 3 is pressed by the pre-bending slope 6b and pre-bent, and the front floor 2 is clamped between the pad surface 6a and the support jig 5. Subsequently, the pre-bending pad 6 rises while being biased downward by the coil spring 6e.

[0007] As shown in Figure 8(E), as the receiving jig 5 rises further, the pre-bent locking claw 3a is pressed by the main bending pad 7, which is fitted into the guide groove 6c of the pre-bending pad 6, and bent until it is in close contact with the front floor 2. This fixes the side member 3 to the front floor 2 and manufactures the vehicle body part 1. [Prior art documents] [Patent Documents]

[0008] [Patent Document 1] Japanese Utility Model Publication No. 59-194381 [Overview of the project] [Problems that the invention aims to solve]

[0009] In the device described in Patent Document 1, the bending pad P for bending the locking claw 3a of the side member 3 has a bulky configuration due to having a preliminary bending pad 6 and a main bending pad 7, making it unsuitable for bending the locking claw 3a in confined spaces.

[0010] Furthermore, the configuration was complex because the tip of the main bending pad 7 was inserted into the guide groove 6c of the spare bending pad 6.

[0011] Furthermore, in the manufacturing of the body part 1, it was necessary to fully bend the locking claw 3a while the front floor 2 was being held between a pre-bending pad 6 and a receiving jig 5, which had the locking claw 3a pre-bent. Therefore, the manufacturing of the body part 1 was not easy. [Means for solving the problem]

[0012] The present invention has been made to solve at least one of the above problems, and an automotive composite part manufacturing apparatus according to one aspect of the present invention is an automotive composite part manufacturing apparatus in which a metal part is fixed to the part to be mounted by bending the locking claw of a metal part that is inserted through a locking hole of the part to be mounted, An arm that presses and bends the locking claw by rotating, A support member that supports the above-mentioned mounting component and the above-mentioned metal component with the locking claw inserted through the locking hole, and that supports the above-mentioned arm so that it can rotate, The system comprises a base member positioned at a distance from the support member described above. With respect to this base member, the support member is biased in a direction away from it and is also capable of moving toward it. The support member is characterized in that a pusher for pushing and rotating the arm is supported on it so as to be slidable and in contact with the base member, while penetrating the support member in the direction of separation between the support member and the base member.

[0013] According to the above configuration, as the support member moves closer to the base member, the pusher that contacts the base member moves relative to the support member, pushing and rotating the arm. The rotating arm presses against and bends the locking claw of the metal part, thereby fixing the metal part to the part to be attached, and a composite part is manufactured. After moving closer to the base member, the support member can return to its original position due to the biasing force. The compact configuration, in which a pusher moves relative to a support member that moves toward the base member, and an arm for pressing the locking claw rotates, allows the locking claw to be bent in confined spaces. To manufacture composite parts, only the support members need to be moved, and the locking claws can be bent without the need for pre-bending as in conventional methods, thus simplifying the manufacturing of composite parts. Furthermore, the configuration for pre-bending the locking claws is unnecessary, resulting in a simpler structure compared to conventional methods and reducing costs.

[0014] Preferably, the support member has a support plate portion facing the base member and a support post portion erected on the side of the support plate portion opposite to the base member. The arm is pivotally supported at the tip of the support post section described above. The pusher penetrates the support post portion and the support plate portion mentioned above. One end of the plunger is capable of contacting the base member, and the other end of the plunger is capable of contacting a position on the arm away from the pivot point. According to the above configuration, the arm is pivotally supported on the support post and the plunger is housed in it, and by concentrating the support of the arm and plunger on the support post, it is possible to reduce the bending space of the locking claw.

[0015] Preferably, the plunger is biased toward the base member while being prevented from coming off toward the base member. According to the above configuration, the pusher rotates the arm by relative movement with the support member which moves closer to the base member, and then returns to its original position due to the biasing force toward the base member as the support member moves away from the base member.

[0016] Another aspect of the present invention is a method for manufacturing an automotive composite part in which a metal part is fixed to a part to be mounted, The process of supporting the component to be mounted and the metal component on a support member while inserting the locking claw of the metal component into the locking hole of the component to be mounted, A step of moving the support member that supports the above-mentioned part to be mounted and the above-mentioned metal part closer to a base member that is positioned at a distance from the support member, The above-mentioned proximity movement brings the pusher, which is supported by the support member and is slidable, in a state where it penetrates the base member in the direction of separation from the support member, into contact with the base member. The above-mentioned proximity movement causes the pusher, which is in contact with the base member, to move relative to the support member, thereby causing the pusher to push and rotate the arm, which is rotatably supported by the support member. A step of fixing the metal part to the attached part by bending the locking claw of the metal part by pressing on the pivoting arm. It is characterized by comprising.

[0017] According to the above configuration, the attached part and the metal part combined by inserting the locking claw into the locking hole are supported by the support member, and by moving the support member toward the base member, the pusher that abuts against the base member moves relative to the support member and presses and rotates the arm supported by the support member. The arm presses and bends the locking claw of the metal part, fixing the metal part to the attached part, and thus a composite part is manufactured. That is, by only moving the support member, the locking claw can be bent without pre-bending, so that the composite part can be easily manufactured.

Effects of the Invention

[0018] According to the present invention, a composite part in which a metal part is fixed to an attached part can be easily manufactured.

[0020] Hereinafter, an embodiment of the present invention will be described with reference to Figures 1 to 7, in the order of automotive composite parts, manufacturing equipment for automotive composite parts, and method for manufacturing automotive composite parts.

[0021] [Automotive composite parts] First, we will explain automotive composite components with reference to Figures 5 to 7. Automotive parts include composite parts made by combining two components; for example, the side sill 10 shown in Figure 7(A) is a composite part. The side sill 10 is a structural member that forms the side of the vehicle body and is located below both doors (not shown). A metal scuff plate 16 (metal part) is placed over and fixed to the upper part of the side sill body 11 (member to be attached). The scuff plate 16 can have the function of protecting the side sill body 11 and also serve a decorative function.

[0022] The side sill body 11 shown in Figures 6(A) and (B) is formed from resin or metal and is elongated along the length of the vehicle. It has a top plate portion 11a and side plate portions 11b and 11c provided at both ends of the top plate portion 11a in the short direction. In the plan view of Figure 6(A), a scuff plate receiving portion 12 is formed in the center of the top plate portion 11a in the longitudinal direction. In this embodiment, it has an uneven, rounded trapezoidal shape. A groove 13 is formed inside the contour line of the scuff plate receiving portion 12.

[0023] Multiple locking holes 14 (12 in this embodiment) are formed in the groove 13 at intervals and penetrate the side sill body 11, as shown in Figure 6(B). The locking holes 14 have an elongated shape along the extending direction of the groove 13 in the plan view in Figure 6(A). The middle portion of the locking hole 14 in the longitudinal direction is formed to be narrower than other portions by a projection 14a protruding from one side wall.

[0024] The scuff plate 16 shown in Figures 5(A) and (B) can be made of a metal such as stainless steel. The scuff plate 16 can have a plan view shape similar to the plan view shape of the scuff plate receiving portion 12 (Figure 6(A)) of the side sill body 11, and in this embodiment, it has an unequal-legged, rounded trapezoidal shape.

[0025] The outer edge of the scuff plate 16 is a bent end 17 that is folded downward, as shown in Figures 5(A), (C), and (D). The bent end 17 is provided with a plurality of locking claws 18 corresponding to the arrangement of the locking holes 14 of the scuff plate receiving portion 12. The locking claws 18 protrude downward, flush with the bent end 17. As shown in Figure 5(C), notches 18a may be formed on one or both sides of the intermediate portion in the protruding direction of the locking claw 18.

[0026] To construct the side sill 10 having the side sill body 11 and scuff plate 16 as described above, as shown in Figure 7(B), the locking claws 18 and bent ends 17 of the scuff plate 16 are inserted into the locking holes 14 and grooves 13 of the side sill body 11, respectively. This positions the scuff plate 16 relative to the side sill body 11. At this time, the locking claws 18 are press-fitted into the portion of the locking hole 14 that has a projection 14a.

[0027] Next, as shown in Figure 7(C), the locking claw 18 is bent in the middle section around the notch 18a (Figure 5(C)). This fixes the scuff plate 16 to the side sill body 11, forming the side sill 10.

[0028] [Manufacturing equipment for automotive composite parts] Next, a manufacturing apparatus 20 capable of producing the above-mentioned side sill 10 (automotive composite part) will be described with reference to Figures 1 to 3.

[0029] The manufacturing apparatus 20 manufactures the side sill 10 by bending the locking claws 18 of the scuff plate 16 (metal part) which is inserted through the locking hole 14 of the side sill body 11 (part to be attached), thereby fixing the scuff plate 16 to the side sill body 11.

[0030] The manufacturing apparatus 20 mainly consists of a base member 30, a support member 40 that supports the side sill body 11 and scuff plate 16 in an assembled state including a support plate portion 41 facing the base member 30, an arm 50 supported by the support member 40 for bending the locking claws 18 of the scuff plate 16, and a pusher 60 that is a member for pushing the arm 50 and is supported by the support member 40.

[0031] In this embodiment, the base member 30 is formed in a plate shape, and a plurality of rod portions 31 (four in this embodiment) are fixed to the base member 30 in a penetrating state and protrude toward the support plate portion 41. The rod portions 31 are inserted into the coil spring 32 and slidably pass through the support plate portion 41. The rod portions 31 are prevented from coming out of the support plate portion 41 by a stopper portion 33 at their tip.

[0032] The coil spring 32 is compressed by the base member 30 and the support plate portion 41, and the support plate portion 41 is biased to move away from the base member 30 and is movable in the direction toward it. The movement of the support plate portion 41 toward the base member 30 is prevented by a stopper portion 34 provided on the base member 30.

[0033] The support plate portion 41 can move closer to the base member 30 against the biasing force of the coil spring 32, and then move away from the base member 30 due to the biasing force of the coil spring 32, returning to its original position.

[0034] In addition to the support plate portion 41, the support member 40 may include a receiving jig 42 erected on the side of the support plate portion 41 opposite to the base member 30, a support column 43 erected on the support plate portion 41 on the same side as the receiving jig 42, a table 44 (upper member) supported by the support column 43 at the tip of the support column 43, a pressing jig 45 (upper member) provided on the table 44, and a support post portion 46 erected on the support plate portion 41 so as to protrude toward the pressing jig 45. Figure 2 shows the manufacturing apparatus 20 with the table 44 and the pressing jig 45, which are upper members of the support member 40, removed.

[0035] As shown in Figure 2, the support plate portion 41 is formed in a rectangular shape in this embodiment, and the rod portions 31 are arranged at each corner.

[0036] The support fixture 42 supports the side sill body 11 with the locking claws 18 of the scuff plate 16 inserted into the locking holes 14. In this embodiment, four support fixtures 42 are provided in a columnar shape, with the back surface of the side sill body 11 resting on their tops. The support fixtures 42 are arranged on the support plate portion 41 in accordance with the shape of the side sill body 11. The number of support fixtures 42 and the height of the support fixtures 42 from the support plate portion 41 can be set arbitrarily.

[0037] The support columns 43 are for supporting the table 44, and in this embodiment, four of them are provided on the support plate portion 41 so as to surround the receiving jig 42. The height of the support columns 43 from the support plate portion 41 is set higher than that of the receiving jig 42. The number and height of the support columns 43 can be set arbitrarily.

[0038] In this embodiment, the table 44 (Figures 1 and 3) has a rectangular shape in plan view and is supported by columns 43 facing the support plate portion 41. Columns 43 are positioned at each corner of the table 44.

[0039] The pressing jig 45 (Figures 1 and 3) supports the scuff plate 16, which has its locking claws 18 inserted through the locking holes 14 of the side sill body 11 supported by the receiving jig 42, by pressing it from the opposite side of the receiving jig 42. The pressing jig 45 is provided on the side of the table 44 opposite to the support plate portion 41, and the contact surface 45a of the pressing jig 45 with the scuff plate 16 can be shaped to correspond to the shape of the scuff plate 16.

[0040] The support post 46 rotatably supports the arm 50 for bending the locking claw 18 of the scuff plate 16, and also slidably supports the pusher 60 for pushing and rotating the arm 50, as shown in Figure 3.

[0041] In this embodiment, the support post portion 46 has a prismatic portion and a bearing portion 46a at its tip for supporting the arm 50. Adjacent to the bearing portion 46a, the support post portion 46 has a through hole 46b for housing the plunger 60, which communicates with a through hole 41a formed in the support plate portion 41. The through holes 46b and 41a extend along the direction in which the support plate portion 41 moves toward and away from the base member 30.

[0042] In this embodiment, the arm 50 has a generally hammer-like shape, and as shown in Figure 3, it has a handle portion 51 at the base end and an external force application portion 52 and a pressing portion 53 that protrude in a direction intersecting the handle portion 51 at the tip end.

[0043] The handle portion 51 is pivotally supported by the bearing portion 46a of the support post portion 46, thereby allowing the arm 50 to rotate. The external force application portion 52 tapers towards the support plate portion 41, and its tip surface has a curved shape.

[0044] The pressing portion 53 is the part that contacts and presses against the locking claw 18 of the scuff plate 16, which is bent by the rotation of the arm 50. It tapers towards the table 44 at the tip end of the external force application portion 52 in the longitudinal direction of the arm 50, and its tip surface has a curved shape. In this embodiment, the radius of curvature of the pressing portion 53 is smaller than the radius of curvature of the external force application portion 52.

[0045] As shown in Figure 3, the pressing portion 53 is formed with a small width in the direction facing the locking claw 18 of the scuff plate 16, allowing it to fit into the narrow space between the locking claw 18 and the side plate portion 11b of the side sill body 11. This contributes to enabling the bending of the locking claw 18 without causing interference between the arm 50 and the side sill body 11.

[0046] In this embodiment, the plunger 60 is formed in a rod shape and has a head portion 61, a neck portion 62, and a body portion 63, and is slidably housed in the through holes 46b and 41a of the support post portion 46 and the support plate portion 41 in a penetrating state.

[0047] The head portion 61 protrudes from the support post portion 46 and contacts the external force application portion 52 of the arm 50. The head portion 61 prevents the plunger 60 from coming out towards the base member 30.

[0048] A portion of the body portion 63 protrudes from the support plate portion 41, and the end face of the body portion 63 faces the base member 30 in a separated state. The end face of the body portion 63 can come into contact with the base member 30 as the support plate portion 41 moves closer to the base member 30.

[0049] A coil spring 70 is attached to the neck portion 62 of the plunger 60. One end of the coil spring 70 abuts against a stepped surface 46c formed in the through hole 46b and facing the support plate portion 41, and the other end abuts against a stepped surface 63a formed in the body portion 63 and facing the table portion 44. As a result, the coil spring 70 is in a compressed state, and the plunger 60 is biased toward the base member 30.

[0050] As the support plate portion 41 moves closer to the base member 30, the plunger 60 comes into contact with the base member 30 and moves relative to the support plate portion 41 and the support post portion 46, resisting the biasing force of the coil spring 70, thereby pushing and rotating the arm 50. Subsequently, as the support plate portion 41 moves away from the base member 30, the plunger 60 can return to its original position due to the biasing force of the coil spring 70.

[0051] The support post 46, which pivotally supports the arm 50 and houses the pusher 60, can be provided on the support plate portion 41 in accordance with the position and number of locking claws 18 of the scuff plate 16 that protrudes from the side sill body 11 supported by the receiving jig 42.

[0052] [Manufacturing method for automotive composite parts] Next, the manufacturing method of the side sill 10 (automotive composite part) using the manufacturing apparatus 20 with the above configuration will be explained with reference to Figures 3 and 4.

[0053] First, as shown in Figure 3, the side sill body 11 is placed on the support jig 42 (Figures 1 and 2) with the locking claws 18 of the scuff plate 16 inserted through the locking holes 14, and the scuff plate 16 is held down and supported by the pressing jig 45.

[0054] Next, as shown in Figure 4(A), when the support plate portion 41 is moved closer to the base member 30, the body portion 63 of the plunger 60 comes into contact with the base member 30, as shown in Figure 4(B). If the movement of the support plate portion 41 continues, as shown in Figure 4(C), the plunger 60 moves relative to the support plate portion 41 and the support post portion 46, and the head portion 61 pushes the external force application portion 52 of the arm 50 pivotally supported by the support post portion 46. As a result, the arm 50 rotates, and the pressing portion 53 presses against the locking claw 18 of the scuff plate 16.

[0055] Furthermore, as the support plate portion 41 continues to move closer to the base member 30, the locking claws 18 of the scuff plate 16 are bent by the arm 50, as shown in Figure 4(D). As a result, the scuff plate 16 is fixed to the side sill body 11, and the side sill 10 (Figure 7) is manufactured.

[0056] After the side sill 10 is manufactured, the support plate portion 41, which has moved closer to the base member 30, can move away from it and return to its original position due to the biasing force of the coil spring 32. Consequently, the pusher 60, which rotated the arm 50 by moving relative to the support plate portion 41 and the support post portion 46, can return to its original position due to the biasing force of the coil spring 70.

[0057] [Effects of the Embodiment] According to the above embodiment, the side sill 10 can be manufactured simply by moving the support plate portion 41, and the locking claws 18 of the scuff plate 16 can be bent without pre-bending as in the conventional example, thus making the manufacturing of the side sill 10 easy. In the manufacturing apparatus 20, since there is no need for a configuration for pre-bending the locking claws, the structure is simpler compared to conventional examples, and costs can be reduced. Because the arm 50 that presses the locking claw 18 is rotated by a pusher 60 that moves relative to the support plate portion 41 and support post portion 46 that move toward the base member 30, the locking claw 18 can be bent in a narrow space. By pivotally supporting the arm 50 on the support post 46 and housing the plunger 60, and consolidating the support of the arm 50 and plunger 60 on the support post 46, it is possible to reduce the space required for bending the locking claw 18.

[0058] [Differentiation] It should be noted that the present invention is not limited to the embodiments described above, and various modifications can be adopted without departing from the spirit of the invention. In the above embodiment, a side sill was given as an example of an automotive composite part, but automotive composite parts are not limited to side sills, and composite parts other than side sills may be manufactured using the manufacturing equipment. [Industrial applicability]
