Description

Detailed Description of the Invention [Industrial Field of Application] The present invention relates to a door transport method that holds and transports a door so that a pair of upper and lower hinge members of a vehicle body and a pair of upper and lower hinge members of a door are engaged with each other. means are provided, and hinge pin attachment means is provided for penetrating and attaching a headed hinge bin across each of said hinge members in the engaged state, said hinge pin attachment means being inserted into the interior of the hinge member of the door to secure the hinge pins when said hinge pins are attached. The present invention relates to an automobile door assembly bag provided with a pair of upper and lower deformation prevention members that prevent deformation of the members.

[Conventional technology]

In this type of automobile door assembly device, the door transfer means receives the door at the door receiving location and transfers it to the door engagement location. The hinge pin is attached to the hinge member at the door engagement location.

A deformation prevention member is engaged with a hinge member of the door to position and hold the door when the door is received at the door receiving location. Then it is supposed to hold the door. At this time, the deformation prevention member has conventionally been fixedly installed or moved by an actuator such as a motor.

[Problem to be solved by the invention]

In the above conventional technology, when the deformation prevention member is engaged with the door hinge member, if there is a positional deviation between the deformation prevention member and the door hinge member due to an installation error of the hinge member, etc.
There was a risk that engagement would not be possible.

An object of the present invention is to eliminate the above-mentioned conventional drawbacks.

[Means to solve the problem]

In order to achieve this object, a first feature of the automobile door assembly device according to the present invention is that at least one of the deformation prevention members is supported so as to be movable up and down, and the distal end thereof is formed in a tapered state. It is that you are.

A second characteristic configuration is that the vertically movable deformation prevention member:
It is configured to move downward under its own weight, and its distal end edge is formed in an inclined shape such that the distal end is located upward.

[For production]

In the first characteristic configuration, even if there is a positional shift between the deformation prevention member and the door hinge member, the tip of the deformation prevention member comes into contact with the door hinge member and moves up and down due to the contact force. Become.

As a result, they can be engaged.

In a second feature, the deformation prevention member is in a lowered position before engagement with the door hinge member. Then, as the two are brought into contact to engage with each other, they rise and engage with the hinge member of the door.

〔Effect of the invention〕

In the first characteristic configuration, the deformation preventing member can be reliably engaged with the hinge member of the door, so that the reliability of the device can be made high.

Further, since the positional deviation is corrected by using the contact force when engaging them, the structure can be simpler than a structure in which an actuator is provided to move the parts.

In the second characteristic configuration, the deformation prevention member is positioned downward using its own weight, and is inserted while being moved upward by contact with the hinge member, so that the deformation prevention member is inserted using a spring or the like. This can be made simpler than a structure in which the holder is biased and held at an intermediate position between the upper and lower sides, and is inserted while being moved upward or downward by contact with a hinge member.
