Parallel control mechanism for upper and lower workbenches of cutting machine

Abstract

The invention discloses a parallel control mechanism for the upper and lower workbenches of a cutting machine, comprising a left-front moving column, a left-rear moving column, a connecting rod, a left-front guide sleeve, a left-rear guide sleeve, a left connecting block and a right connecting block, as well as a left V-shaped steering block and a right V-shaped steering block, wherein the distance between the axis of the left-front guide sleeve and the axis of a right-front guide sleeve is 3360 mm; the distance from the hinged point of the lower end of the left connecting block and one end of the left V-shaped steering block to the axis of a left pin shaft is 300 mm; the angle of the left V-shaped steering block is 109.23 degrees; the distance from the axis of the left pin shaft to the left hinged point of the other end of the left V-shaped steering block and the connecting rod is 470.03 mm; the distance from the hinged point of the lower end of the right connecting block and one end of the right V-shaped steering block to the axis of a right pin shaft is 300 mm; the angle of the right V-shaped steering block is 109.23 degrees; the distance from the axis of the right pin shaft to the right hinged point of the other end of the right V-shaped steering block and the connecting rod is 470.03 mm; and the distance between the hinged points at the both ends of the connecting rod is 2640.06 mm.

Description

technical field [0001] The invention relates to a cutting machine, in particular to a parallel control mechanism for the upper and lower working tables of the cutting machine. Background technique [0002] The blanking of existing non-metallic materials is usually completed by equipment such as cutting machines. Existing cutting machines usually contain a parallel control mechanism for upper and lower worktables. The main function of the control mechanism is to keep the upper workbench and the lower workbench to move up and down in parallel during the cutting process. An existing parallel control mechanism for the upper and lower worktables of a cutting machine mainly includes an upper workbench, a lower workbench, an oil cylinder, a moving column, and a connecting rod. Both are equipped with the moving columns, the upper ends of the moving columns are respectively set on the bottom of the upper workbench, the lower ends of the moving columns are respectively set on the lef...

AI Technical Summary

Problems solved by technology

In the parallel control mechanism of the upper and lower worktables of the cutting machine, due to the influence of the relative position relationship parameter selection of the relevant parts, the moving columns on the left and right sides are not synchronized during the up and down movement, and the absolute average value of the error exceeds 0.5 mm, so that the upper table and the lower table are not parallel, so it is easy to cause insufficient or excessive cutting volume, which brings quality problems and economic losses
