Tool gauge for precisely drawing hyperbolic curve

Abstract

The invention discloses a tool gauge for precisely drawing a hyperbolic curve, and relates to the technical field of tool gauges. The tool gauge comprises a ruling pen and a limiting device; the ruling pen comprises line lump devices, a center column and a pen sleeve device; the line lump devices comprise the upper line lump device and the lower line lump device; the peripheral side face of the center column is matched with the upper line lump device and the lower line lump device; the lower end face of the lower line lump device is rotationally connected with a first round limiting groove; the limiting device comprises a handle, an origin fixing column and focus fixing columns; one side face of the handle is provided with a first rectangular through hole and a second rectangular through hole; the first rectangular through hole is in slide fit with the peripheral side face of the first focus fixing column of the focus fixing columns; and the second rectangular through hole is in slidefit with the peripheral side face of the second focus fixing column of the focus fixing columns. According to the tool gauge, through action of the ruling pen and the limiting device, the problems that when a hyperbolic curve is drawn during study and work, large errors exist, and the required hyperbolic curve cannot be comprehensively drawn out are solved.

Description

technical field [0001] The invention belongs to the technical field of tool gauges, and in particular relates to a tool gauge for accurately manufacturing hyperbolas. Background technique [0002] In the learning and application of hyperbolic knowledge, it is usually necessary to make hyperbolic geometric figures. In the production of graphics, it is necessary to use some specific tools, generally using tools such as rulers and compasses. For the production of hyperbolas , people usually use the "find point tracing method" and other methods to complete. Therefore, in study and work, when people need to draw a hyperbola, there is a large error, and the required hyperbola cannot be fully drawn. [0003] In view of the above problems, the present invention uses the marking pen and the stop device, the first thin line is PF 1 The length of the second thinnest line is PF 2 The length, the distance between the two fixed focus columns of the limit device is F 1 f 2 ;The rotati...

[0004] The object of the present invention is to provide a tool gauge for accurately making hyperbolas. Through the action of a marking pen and a limit device, the first thin line is PF 1 The length of the second thinnest line is PF 2 The length, the distance between the two fixed focus columns of the limit device is F 1 f 2 ;The rotation of the center column in the scribe pen can adjust the length of the first thin line and the second thin line at the same time, that is, increase or decrease the PF at the same time 1 、PF 2 The length of the torque; the torque control rocker controls the distance F between the two focal points 1 f 2 , that is, adjusting F 1 f 2 The length of the fixed origin column is used to determine the position of the origin, and the two fixed focus columns are used to determine the position of the two focal points; it has precise control distance and increases or decreases PF at the same time 1 、PF 2 length, precise control of O, F 1 , F 2 The characteristics of the distance between the three points solve the problem that there is a large error when making a hyperbola in the study and work, and the problem that the required hyperbola cannot be drawn comprehensively
