The concrete use of the backing rail and the pedal upright welding mold of the translational limit type vehicle door frame of the embodiment is as follows:
firstly, as shown in fig. 1, 2, 4 and 5, a rear rest 1a is mounted on a rear rest positioning tool on a rear rest positioning frame (a door lock mounting plate 1a.1 for mounting a door lock is arranged on the rear rest), the rear rest is positioned in a rear rest positioning groove on a rear rest positioning block, and the lower end of the rear rest is abutted against a lower rear rest limiting block; and then the rear leaning stop is pressed on the rear leaning stop positioning block through the pressing plate, so that the rear leaning stop is positioned and installed on the rear leaning stop positioning tool.
The pedal upright post 1b is arranged on the pedal upright post positioning tool (the pedal upright post comprises a front upright post 1b.1 and a vehicle door hinge mounting plate 1b.2 which is arranged on the front upright post and is used for mounting a vehicle door hinge), wherein,
the pedal upright post is supported at the upper end of the vertical strut of the first support column and the upper end of the second support column; the side limiting block is used for carrying out side positioning on the pedal upright post; the two vertical pedal positioning pins are matched with the fabrication holes on the pedal upright column to position the pedal upright column;
then, the pedal upright post is pressed on the second support column through the pedal upright post quick clamp; thereby positioning and installing the pedal upright post on the pedal upright post positioning tool.
Secondly, as shown in fig. 1, a door lock mounting plate 1a.1 for mounting a door lock on a rear stop and a door hinge mounting plate 1b.2 for mounting a door hinge on a pedal pillar are limited by a translational door frame limiting device, and the specific operations are as follows:
an operator holds the operating rod to push forwards (namely the operator holds the operating rod to push the sliding seat towards the front limiting block of the sliding seat), when the sliding seat abuts against the front limiting block of the sliding seat, the sliding seat stops moving, at the moment, the door lock limiting plate and the hinge limiting plate are positioned between the door lock mounting plate and the door hinge mounting plate, the door lock limiting plate is close to the door lock mounting plate, and the hinge limiting plate is close to the door hinge mounting plate (in the process, the operating rod and the sliding seat do not move relatively due to the action of a pre-tightening compression spring);
then, the operator holds the operating rod and continues to push forwards to overcome the elasticity of the pre-tightening compression spring, so that the pre-tightening compression spring is compressed (the holding operation is close to the sliding frame), the driving push rod is driven to move forwards until the first end of the limiting rod extends into the annular clamping groove under the action of the limiting rod pressure spring, and at the moment, the operator releases the operating rod;
in the process of driving the push rod to move forwards, the first slide block and the door lock limiting plate are driven by the first connecting rod to be close to the door lock mounting plate, so that the door lock limiting plate is abutted against the door lock mounting plate, the second slide block and the hinge limiting plate are driven by the second connecting rod to be close to the door hinge mounting plate, and the hinge limiting plate is abutted against the door hinge mounting plate; therefore, the relative position of the door hinge mounting plate and the door lock mounting plate is limited, the accuracy of the relative position of the door hinge mounting plate and the door lock mounting plate is effectively improved after the rear bumper and the pedal upright post are welded into a whole, and the problem that the door lock part on the door cannot be smoothly matched with the door lock part on the door lock mounting plate after the door is mounted on the door hinge mounting plate through the door hinge because the relative position of the door hinge mounting plate and the door lock mounting plate is not in accordance with the design requirement after the rear bumper and the pedal upright post are welded into a whole due to welding deformation or other reasons is effectively avoided.
Thirdly, the pedal upright post and the rear leaning block are connected into a whole by welding.
Fourthly, the limiting rod is pulled out manually, so that the limiting rod is separated from the annular clamping groove; when the limiting rod is separated from the annular clamping groove, under the action of pre-tightening the compression spring, the operating rod moves towards the operating rod limiting block until the operating rod abuts against the operating rod limiting block; meanwhile, the first sliding block is reset under the action of the first tension spring, so that the door lock limiting plate abuts against the door lock mounting plate to be separated; the second sliding block is reset under the action of a second tension spring, so that the hinge limiting plate is abutted against the vehicle door hinge mounting plate to be separated;
then, the operator holds the operating rod to push backwards (namely, the operator holds the operating rod to push the sliding seat towards the rear limiting block of the sliding seat) until the sliding seat abuts against the rear limiting block of the sliding seat;
and then, disassembling the rear backrest gear positioning tool and the pedal upright post positioning tool, and taking out the pedal upright post and the rear backrest gear which are welded and connected into a whole.
