Lifting clamping device for car door conveying line

Abstract

The invention relates to a lifting clamping device for a car door conveying line. The lifting clamping device comprises a fixing bracket and a movable sliding seat, wherein a lower rack is installed on the fixing bracket; an upper rack is installed through a vertical rod, a cross rod and a guiding sliding block on the movable sliding seat; an operating handle is arranged at the top of the vertical rod through a lever arm; the guiding sliding block is connected to one end of the operating handle; and the engagement or disengagement of an upper rack and a lower rack can be realized through the operating handle. When the upper rack and the lower rack are engaged, the lifting clamping device is in a clamping working state; when the upper rack and the lower rack are disengaged, a movable object can move leftwards and rightwards relative to the fixing bracket so as to achieve the purpose of adjusting the position of a clamping block leftwards and rightwards. The lifting clamping device has the advantages of strong practicability, safety and reliability and can meet the requirements of line-to-line production assembly of various car models through adjusting and clamping car doors of different widths and sizes.

Description

technical field [0001] The invention relates to a hoisting and clamping device, in particular to a hoisting and clamping device for a car door conveying line. Background technique [0002] According to conventional car assembly workshops, door conveying lines are generally arranged. The transportation process of the door conveying line is as follows: first, at the door dismantling station of the interior decoration line, the manipulator removes the painted door from the body and transfers it to the door line. It is transported to the sub-assembly area for door assembly; then the assembled door is transported to the assembly station on the final assembly line and reassembled on the vehicle. The original car door hoisting and clamping device is: the left side and the bottom are fixed support points, and the right side is a slidable clamping support point. Since the slidable clamping support point in the original technology uses a hinge four-bar mechanism, this mechanism relie...

AI Technical Summary

Problems solved by technology

Since the slidable clamping support point in the original technology uses a hinge four-bar mechanism, this mechanism completely relies on the dead point position formed by the hinge four bars to form a self-lock to achieve the purpose of clamping. This mechanism is used in the door conveyor line The fixture used to clamp the car door has poor reliability. If the conveying line is impacted or vibrated, the mechanism will easily bypass the dead point and the clamping support point will become loose, so that the clamped car door will fall off the conveying line. great safety hazard
