A Curve Plotter Used for Processing Special-shaped Workpieces

Abstract

The invention discloses a curve plotter for special-shaped workpiece machining. The curve plotter for special-shaped workpiece machining comprises a bottom plate, positioning drawbenches and positioners arranged on the drawbenches in a penetrating mode. The positioning drawbenches and movable blocks at the two ends of the positioning drawbenches are arranged in multiple groups and are arranged in a mutually perpendicularly intercrossing mode. Each positioning drawbench is tensioned through the movable blocks at the two ends of the positioning drawbench and moveably connected to two end faces of the bottom plate. The bottom plate is provided with a scale grid, and positioning through holes for dot drawing are formed in the intersections of lines of the scale grid of the bottom plate. According to the curve plotter for special-shaped workpiece machining, a special-shaped workpiece is placed on the scale grid of the bottom plate to be positioned, then the positioning drawbenches and the positioners are moved, the positioners correspond to the outer contour of the special-shaped workpiece in a one-to-one mode, and the contour line is drawn by conducting dot drawing and line connecting through the positioning through holes. A double-layer transparent plate with paper inserted in the middle can serve as the bottom plate. Coordinate point conversion can be directly conducted according to the scale grid. The scaled-up or scaled-down contour line can be directly drawn through the positioning through holes. Efficiency is high, and rapidness and accuracy are achieved.

Description

technical field [0001] The invention relates to a plotter, in particular to a curve plotter. Background technique [0002] Existing plotters cannot copy, enlarge or reduce special-shaped workpieces very well. They can only measure and calculate special-shaped workpieces in other ways, and draw their processing curves according to geometric principles. The efficiency is often low, and it is impossible to quickly and accurately The processing curve of the special-shaped workpiece is drawn. Contents of the invention [0003] Purpose of the invention: The purpose of the present invention is to address the deficiencies in the prior art and provide a curve plotter for processing special-shaped workpieces, which can improve the positioning efficiency of processing curves for special-shaped workpieces. [0004] Technical solution: A curve plotter for processing special-shaped workpieces according to the present invention, including a bottom plate, a positioning wire and a locator...
