Description

  The present invention relates to, for example, a door fixing jig for fixing a door at a predetermined opening in a painting process of an automobile production line, and a door opening / closing method using the door fixing jig. The door is prevented from opening and closing due to vibration during transportation, etc., the door is securely held at a predetermined opening, the jig is downsized, and the paint peeled off from the jig adheres to the vehicle body. The present invention relates to a door fixing jig and a door opening / closing method using the door fixing jig that can prevent the occurrence of poor coating.

In the painting process of the automobile production line, the paint color tone and luster of the door and the body surface are the same, so the door is fixed at a predetermined opening with respect to the body during painting. Various coating operations such as undercoating, intermediate coating, and topcoating are performed.
For example, in the undercoating process, the door opening with respect to the vehicle body is fixed to make the cleaning solution easily enter the vehicle body. In the intermediate coating and overcoating process, the color tone and gloss of the door and the vehicle body are fixed. In order to make the same, the painting work is performed with the door fixed to the closed state with respect to the vehicle body. Thus, in order to fix a door to a vehicle body in a painting process, a door fixing jig is used.
For example, in Patent Document 1, a door opening / closing auxiliary device in which a plate-like magnet is fixed to a substrate via a shock absorber by a spring member is attached to a side sill portion of a vehicle body, and the magnet is attracted and held on an inner panel of the door. A technique for holding a door in a closed state and absorbing excessive pressing force on the door with a shock absorber is disclosed.

Japanese Utility Model Publication No. 61-006481

However, in the above prior art, since many uneven portions are formed on the inner panel of the door, it is difficult to firmly adsorb the magnet and the inner panel. When an opening force is applied, the door and the magnet are likely to be separated from each other, and the door may be opened during conveyance. Moreover, in order to improve the holding force of a door, it is necessary to use a large sized magnet beforehand.
In addition, although the excessive pressure can be absorbed by the shock absorber, the door is composed of a bag-like portion in which door components such as a door regulator and a window glass are stored, and a door sash portion that guides the window glass to be raised and lowered, Since the door sash part is less rigid than the bag-like part, the door sash part is easy to bend, and the door opening flange part on the upper side of the vehicle body and the door may come into contact with each other due to vibration during transportation, etc.
Furthermore, when a jig is used after painting the inner panel of the door, the paint film on the magnet's attracting surface peels off, the peeled paint adheres to the vehicle body, resulting in poor painting, or paint that adheres to the jig. There is a risk that it will peel off and adhere to the door step, side sill, etc., resulting in poor coating.
Therefore, the present invention prevents a door from opening and closing due to vibration during conveyance, and can securely hold the door and reduce the size, and a door opening and closing method using the door fixing jig Is to provide.

  In order to achieve the above object, the invention described in claim 1 is a door fixing jig that fixes a door (for example, door D in the embodiment) to a vehicle body at a predetermined opening degree in a painting process of the vehicle body. The vehicle body side jig (for example, the vehicle body side jig A in the embodiment) positioned and fixed in the vicinity of the pillar portion of the vehicle body (for example, the center pillar S in the embodiment), and the inner panel (for example, implementation) of the door Door-side jig (for example, the door in the embodiment) that is positioned and fixed in a gap (for example, the door waist opening D3 in the embodiment) between the inner panel D2) and the outer panel (for example, the door skin D1 in the embodiment). Side jig B), and a connecting jig for connecting the vehicle body side jig and the door side jig (for example, the connecting jig C in the embodiment), Fixing means (for example, the engaging portion 2 and the connecting jig body 17 in the embodiment) for detachably fixing the connecting jig and the vehicle body side jig is provided, and the connecting jig and the door side jig Adsorption that is uniformly adsorbed on a magnetized surface (for example, the opening edge 25b of the holder 25 in the embodiment, the magnet 23) by the magnet (for example, the magnet 23 of the connecting jig C in the embodiment) provided on the other side. A surface (for example, the suction plate 11 of the door side jig B in the embodiment) is provided.

  The invention described in claim 2 is configured such that the magnetized surface by the magnet and the attracting surface can be attracted by a surface directed to the side of the vehicle body, and either the magnetized surface by the magnet or the attracting surface is provided. One is supported so as to be swingable about the side of the vehicle body as an axis with respect to the other.

  According to a third aspect of the present invention, an elastic member that holds the magnetized surface by the magnet or the attracting surface in a direction toward the inside of the vehicle body on either the magnetized surface by the magnet or the attracting surface (for example, The compression spring 29) according to the embodiment is provided.

  The invention described in claim 4 is characterized in that the contact position between the magnetized surface by the magnet and the attracting surface is set on the vehicle inner side than the vehicle body member constituting the lower side of the door attachment opening of the vehicle body. And

  The method invention described in claim 5 is a door opening / closing method in the case of transporting the vehicle body in a state where the door is fixed to the vehicle body using the door fixing jig, and the door of the vehicle body is opened when the door is closed. The vehicle body is transported with the vehicle body tilted to make the supporting side higher than the opposite side, and when the door is opened, the side of the vehicle body that supports the door is made lower than the opposite side. The vehicle body is conveyed with the vehicle body tilted.

According to the first aspect of the present invention, there is an effect that the door is not damaged as compared with a case where the magnet is directly attracted to the inner panel of the door.
In addition, since the attracting surface that attracts evenly with respect to the magnetized surface by the magnet is provided, the attracting force is increased, and the door can be securely held and fixed to the vehicle body even if vibration during transportation acts. is there. Therefore, unlike the case where the magnet is attracted to a non-flat portion such as the inner panel of the door, it is not necessary to strengthen the magnet in order to sufficiently secure the attracting force, and the magnet, that is, the jig can be reduced in size.
According to the second aspect of the present invention, even when the force is received with the door tilted with respect to the vehicle body, the contact surface between the magnetized surface and the attracting surface is not separated. Since the suction state is uniformly maintained, there is an effect that the door can be securely held and fixed to the vehicle body.
According to the third aspect of the present invention, the force to open the door is attenuated by the elastic force of the elastic member, and the impact force during transportation is absorbed by the elastic member. The magnetic surface and the attracting surface are not easily separated from each other, and the door can be securely fixed.
According to the invention described in claim 4, it is possible to prevent the coating material peeled off from the magnetized surface by the magnet or the attracting surface from falling on the vehicle body member constituting the lower side of the door mounting opening and causing poor coating. effective.
According to the invention described in claim 5, when the door is closed, the door can be reliably kept in the closed state by adopting a forward leaning posture with respect to the front end direction of the vehicle body, and when the door is opened. By setting the posture to lean backward relative to the front end direction of the vehicle body, the door opens with its own weight, and the door opening operation force increases by the amount that the magnetized surface by the magnet and the attracting surface are securely attracted. There is an effect that can be reduced by using such force.

6 is a perspective view of the connecting jig C, and FIG. 7 is a bottom view of the connecting jig.
As shown in FIGS. 6 and 7, the connecting jig C includes a connecting jig main body 17 that is detachably attached to the engaging portion 2 of the vehicle body side jig A, and a connecting member 18 attached to the connecting jig main body 17. And a magnet part 19 attached via the.

  The connecting jig main body 17 is formed by bending a round bar-shaped steel material downward substantially at a right angle, and is tapered in parallel to the first leg portion 20a with a certain distance from the first leg portion 20a. A second leg 20b is provided. Here, the distance between the first and second leg portions 20a, 20b is set to be the same as the distance between the cylindrical members 8a, 8b of the vehicle body side jig A. The first and second leg portions 20a, 20b are formed to have a slightly smaller diameter than the inner diameter of the cylindrical members 8a, 8b of the vehicle body side jig A, and are inserted without rattling. Ring members 21a and 21b are press-fitted into the base portions of the portions 20a and 20b, respectively. The ring members 21a and 21b improve the sitting of the connecting jig C and eliminates rattling when the first and second leg portions 20a and 20b are inserted into the cylindrical members 8a and 8b of the vehicle body side jig A. Yes.

  The case where two first and second leg portions 20a and 20b are provided has been described as an example. However, if the connection jig C is restricted from rotating with respect to the vehicle body side jig A, the number and shape are not limited. It is not limited. In addition, for example, the cylindrical members 8a and 8b may be formed in a quadrangular prism shape on each of the first and second leg portions 20a and 20b, and when such a quadrangular prism shape is adopted, the first and second Since the rotation of the leg portions 20a and 20b is restricted even at one location, it is only necessary to provide one cylindrical portion.

  The magnet unit 19 includes a rod end 22 fixed to the connecting member 18 with a bolt 24. The rod end 22 is a known sliding bearing member provided with a spherical inner ring 22a at the tip. Bolts 26 are inserted into the spherical inner ring 22 a at right angles to the longitudinal direction of the rod end 22. A compression spring 29 and a washer 28 are sequentially inserted into the bolt 26 from the head 26a side, and a cylindrical holder 25 is screwed and fixed to the tip of the bolt 26 through a spacer 27 at a portion protruding from the spherical inner ring 22a. . A magnet 23 is inserted into the holder 25. Here, the holder 25 is a bottomed cylindrical member, and the opening edge 25b of the holder 25 and the outer surface of the magnet 23 are configured as magnetized surfaces, and are formed on the suction surface 11b of the suction plate 11 of the door side jig B. It will come into contact and adsorb.

A screw hole 25c screwed with the bolt 26 is formed in the bottom 25a of the holder 25, and the spacer 27 is fastened and fixed to the bottom 25a of the holder 25.
Therefore, the holder 25 is held horizontally by the elastic force of the compression spring 29, and when the holder 25 receives a force in the tilting direction, the spherical inner ring 22a tilts, so the holder 25 is necked with respect to the rod end 22. It will be supported in a swingable manner.

Next, the operation will be described.
First, with the door D opened, as shown in FIG. 2, the hook portion 3a of the frame 3 of the vehicle body side jig A is engaged with the component mounting hole S1 formed in the center pillar S and the clamping member 5 is engaged. The groove portion 5a is engaged with the front side edge S2 of the center pillar S, and the vehicle body side jig A is positioned and mounted on the center pillar S of the vehicle body.

  4 and 5, the positioning member 15 of the door side jig B is engaged with the front edge portion of the stiffener SF joined to the inner panel D2, and the engaging member 14 of the door sash DS is engaged. The stiffener SF and the inner panel D2 are passed through the female threaded portion 16a of the locking member 16 provided at the lower portion and engaged with the groove portion DS1, and the fixing bolt 31 is tightened and fixed from the inside of the vehicle body.

Next, as shown in FIG. 8, the first and second leg portions 20a and 20b of the connecting jig C are inserted into the cylindrical members 8a and 8b of the car body side jig A, and the connecting jig is inserted into the car body side jig A. Wear C.
At this time, the tip of the magnet 23 of the connecting jig C is located on the vehicle interior side from a door step (not shown) which is a vehicle body member constituting the lower side of the door attachment opening of the vehicle body.
Then, when the door D is closed with the vehicle body side jig A, the door side jig B, and the connection jig C mounted, the connection jig C is placed on the suction surface 11b of the suction plate 11 of the door side jig B. The opening edge 25b of the magnet 23 and the holder 25 is attracted as a magnetized surface, the connecting jig C connects the vehicle body side jig A and the door side jig B, and the door D is fixed to the vehicle body.

Further, even if the door D receives a force on the open side due to vibration during transportation, the bolt 26 can swing around the central axis of the spherical inner ring 22a of the rod end 22 and holds the magnet 23 25 is swingable, the opening edge 25b of the magnet 23 and the holder 25 is in surface contact with the suction plate 11 so that the magnetic force is uniform, and the door D is opened by the elastic force of the compression spring 29. Since the force to be attenuated and the impact force due to vibration are absorbed, the magnet 23 and the holder 25 are not easily separated from the suction plate 11.
In addition, what is necessary is just to pull a door with the force more than the magnetizing force of the magnet 23 and the holder 25, and the adsorption | suction plate 11, when opening the door D. FIG.

Here, when the door D is closed at a predetermined position, the length of the connecting member 10 of the door-side jig B is previously set so that the magnet 23 of the connecting jig C is attracted to the suction plate 11 of the door-side jig B. Therefore, the opening degree of the door D can be easily changed simply by changing the length of the connecting member 10.
3 and 5, a hook 32 is attached to the upper surface of the bent portion 12b of the frame 12 of the door side jig B, so that the door opening / closing device (not shown) or the door D by the operator The opening operation can be easily performed.

  FIG. 9 is a perspective view of the lock member. In the intermediate coating and top coating process of the automobile production line, as described above, the vehicle body side jig A and the door side jig B are connected by the connecting jig C so that the door D is closed. In the undercoating process, which is a process, as shown in FIG. 10, the door D is fixed with respect to the vehicle body with the opening degree increased using the lock member 33 without attaching the connecting jig C.

  Specifically, the lock member 33 includes first and second leg portions 33a and 33b having the same configuration as that of the connecting jig C, and an arm portion 34 extending outward from the first and second leg portions 33a and 33b. A locking end 35 that extends downward is provided at the end of each. The arm portion 34 is set to a length that ensures a sufficient opening for the electrodeposition liquid in the undercoating process to flow into the vehicle body. Here, a ring member 34b is provided at the base of the second leg portion 33b. By simply replacing the lock member 33 configured in this manner with the connecting jig C, it is possible to cope with a change in the holding posture of the door D, that is, when the door D is held open.

FIGS. 11-13 is the figure which showed the condition which conveys a vehicle body in the state which fixed the door D using the door fixing jig mentioned above.
As shown in FIG. 11, the cart body 101 that travels on the rail 100 via the guide G (on the left side in FIG. 11) swings to place the vehicle body with the rear end facing upstream in the traveling direction. The plate 102 is disposed so as to be tiltable about the downstream axis J, and a pair of rollers 103 are disposed on the rear side of the swing plate 102 in the width direction of the swing plate 102.

  As shown in FIG. 12, in the step of opening the door D, guide rails 104 and 104 that engage with the roller 103 are provided outside the rails 100 and 100. Both ends of the guide rails 104 and 104 are inclined obliquely downward, and a horizontal portion of an elevated floor is formed in the center. The rollers 103 and 103 ride on the end of the guide rails 104 and 104 on the upstream side in the traveling direction. When the ascending horizontal portion is reached, the rocking plate 102 tilts forward with respect to the traveling direction about the axis J, and the vehicle body leans forward with respect to the front end direction of the vehicle body.

Here, normally (when the door is closed), the swing plate 102 is in a rearward tilted state where the upstream side in the traveling direction is lowered downward (see FIG. 11), and the vehicle body is tilted rearward with respect to the front end direction, that is, By tilting the side supporting the door D (the hinge side) to a higher state than the side not supporting the door D, a force in the closing direction acts on the door D to maintain the closed state of the door D. The door D is prevented from opening.
In addition, when the door is opened, the rollers 103 and 103 run on the guide rails 104 and 104 so that the swing plate 102 is tilted forward in the traveling direction, and the vehicle body is tilted forward with respect to the front end direction. By tilting the side that supports the door D (the hinge side) to a lower state than the side that does not support the door D, a force in the opening direction acts on the door D, and the opened state is maintained by its own weight after opening.

  By using such a transport conveyor, when the door D is normally closed and transported, the swing plate 102 is tilted rearward with respect to the front end direction of the vehicle body, and the vehicle body is supported in a rearward tilted state and transported. The closing force can be applied to the hinge door D to maintain the closed state, and the magnetic force generated by the door fixing jig, that is, the suction plate 11 of the door side jig B and the magnet 23 of the connecting jig C can be maintained. The door D can be reliably fixed by the magnetic force.

When the door 103 is opened, when the rollers 103 and 103 ride on the guide rails 104 and 104, the swing plate 102 is tilted forward with respect to the front end direction of the vehicle body, and the vehicle body is supported in a forward tilted posture. Since the opening force acts, the suction state between the magnet 23 of the door fixing jig and the suction plate 11 can be easily released, and the door D is opened by its own weight after opening.
Accordingly, the door D can be firmly fixed to the vehicle body by the magnet 23 and the suction plate 11 during the above-described intermediate coating / top coating process, so when the door D needs to be opened in the next process. An extra force is required for the operator's opening operation of the door D. By changing the tilting state of the swing plate 102 of the carriage body 101 by the guide rail 104 in this manner, It is possible to reduce the burden on the worker by using the own weight.

  According to the above embodiment, the bolt 26 of the connecting jig C attached to the vehicle body side jig A swings around the axis of the spherical inner ring 22a of the rod end 22 so that the holder 25 is necked about the vehicle body side. Since the holder 25 and the magnet 23 can come into contact with the suction surface 11b of the suction plate 11 of the door side jig B, the magnetic force becomes uniform, and the holder D is displaced even when the door D is displaced in the opening direction. 25 and the magnet 23 and the adsorption | suction plate 11 become difficult to space apart. Therefore, the door D can be reliably fixed.

  Further, when the force is applied in the direction in which the door D is to be opened due to the elastic force of the compression spring 29, this force can be attenuated and the impact force during transportation is absorbed. It becomes difficult for the holder 25 and the magnet 23 and the attraction plate 11 to be separated from each other, and the door D can be reliably fixed. Further, since the attracting force between the holder 25 and the magnet 23 and the attracting plate 11 can be ensured, the magnet 23 can be downsized.

Further, since the magnet 23 of the connecting jig C and the suction plate 11 of the door side jig B are sucked inside the vehicle from the door step, the paint peeled off from the suction plate 11 and the like is placed on the door step. It can prevent falling and poor painting.
Further, since the door D is firmly fixed in the vicinity of the center pillar S, which is a vehicle body skeleton member, the door D is not bent and does not come into contact with the peripheral flange or the like of the door mounting opening of the vehicle body. Can prevent scratches.

In addition, this invention is not restricted to the said embodiment, For example, as shown in FIG. 14, the connection jig | tool C is not restricted to the structure using the rod end 22. As shown in FIG. For example, without using the rod end 22, the bolt 26 is inserted into the board 30 having the large-diameter hole 30a, and the compression spring 29, the washer 28, and the spacer 27 ′ are assembled to the board 30 in the same manner as in the above-described embodiment. The holder 25 may be swingable around the central axis within the range of the hole 30a in a state where the holder 25 is horizontal. Alternatively, the bolt 26 may be a bar, and the holder 25 may be fixed to the tip of the bar.
