Plate hoisting frame structure for automobile punch production line

Abstract

The invention provides a plate hoisting frame structure for an automobile punch production line. The plate hoisting frame structure is mainly composed of a machine frame, guiding columns, counteraction wheel mechanisms, tightening mechanisms, a transmission mechanism, hoisting feet and the like. The hoisting feet sleeve the guiding columns to slide, and tightening wheels sleeve tightening seats sothat the tightness of chains can be adjusted. The plate hoisting frame structure is characterized in that pull rod seats are disposed on the upper portions of the hoisting feet, and the counteraction wheel mechanisms are disposed on the lower portions of the hoisting feet; pull rod sleeves which are connected with the pull rod seats through nuts are disposed on the pull rod seats; and pins are disposed on the pull rod sleeves. By means of the hoisting frame structure, pre-tightening of the two ends of the chains can be improved, and thus the problem that the two sides are asynchronous duringreversing due to insufficient pre-tightening force is avoided; and the pressing force of rollers and the guiding columns can be adjusted through the counteraction wheel mechanisms, the bending momentcaused when heavy objects are hoisted is effectively eliminated, and thus the hoisting motion is smoother. A corresponding mechanical feeding structure is configured, material grabbing is performed without a multi-degree-of-freedom robot, and the equipment input cost is greatly reduced.

Description

technical field [0001] The invention belongs to the field of sheet material stamping and forming for automobiles, and in particular relates to a sheet material lifting frame structure for an automobile stamping production line. Background technique [0002] The cold plate feeding part of the existing automobile stamping production line generally adopts a multi-degree-of-freedom robot, which is equipped with an end picker of a certain specification of the plate, and grabs and loads the plate of a certain specification placed on the plane of the workbench; Sheet metal, the trajectory of the robot needs to be reset and the thickness of the sheet needs to be moved down. Due to the limitation of the robot’s downward movement space, the plane height of the workbench must be higher than the limit height of the robot’s downward movement; The higher the action configuration, the higher the cost.
