Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1 to 5, in this embodiment, a vehicle door assembly holding tool for vehicle body welding includes a body frame 1, a vehicle door skirt positioning roller 2 fixedly connected to a lower end of the body frame 1, a vehicle door profile positioning block 10 and a pressing suction cup 3 fixedly connected to a middle portion of the body frame 1, a vehicle door anti-falling mechanism 5 fixedly connected to an upper end of the body frame 1, and a limiting block 6 fixed to a cylinder of the vehicle door anti-falling mechanism 5 through a bolt 8.

In this embodiment, the body frame 1 is used for being connected to a slide rail. The vehicle door skirt positioning roller 2 is used for positioning the vehicle door skirt. The pressing sucker 3 is used for clamping and limiting the Y direction of the vehicle door.

As shown in fig. 1 and 2, in the present embodiment, the door drop prevention mechanism 5 is fixed to the left side surface of the body frame 1 by a four-bar linkage 7, and is opened and closed by using an air cylinder. The positioning block 10 of the outer surface of the vehicle door and the pressing sucker 3 are fixed on the left side surface of the body frame 1; the positioning block 10 on the outer surface of the car door is opened and closed by adopting a cylinder. And the vehicle door skirt edge positioning roller 2 is fixed on the left side surface of the body frame 1.

As shown in fig. 4, in this embodiment, the limiting block 6 is in a stepped cylinder shape, and the middle portion is a cylindrical through hole.

As shown in fig. 1 and fig. 3, in this embodiment, the limiting block 6 is fixedly connected to the door anti-drop mechanism 5 through a bolt 8, and the adjustment of the clamping limiting is realized by increasing or decreasing the shims 9.

In this embodiment, the limiting block 6 and the gasket 9 are made of metal materials.

In this embodiment, the cylinder of the door anti-drop mechanism 5 has a cylinder turning stroke limit.

In this embodiment, the door turning-around prevention portions of the door outer surface positioning block 10 and the door turning-around prevention mechanism 5 are both made of polyurethane materials.

As shown in fig. 6, in this embodiment, the portable electronic device further includes a button, a controller, and a power module, where the power module and the button are electrically connected to the controller respectively. In addition, the cylinder for controlling the door profile positioning block 10 and the cylinder for controlling the door anti-falling mechanism 5 are also electrically connected with the controller respectively. The power module provides the electric energy required by the work for the whole holding tool, and the controller is used for receiving the trigger signal of the button and controlling the corresponding cylinder to work based on the trigger signal.
