Description
Technical field
The utility model relates to Machining Technology field, particularly relates to a kind of line measurement mechanism of large scale special-shaped workpiece.
Background technology
Tradition scribble method utilizes comparatively accurate cast iron platform (being all perform inspection according to international standard usually) to coordinate the workpiece of various general scoring tool to various single-piece or small lot batch manufacture to rule.Common router has: straight steel ruler, scriber, tosecan, vernier height gauge, plan, sample punching, V-type frame, angle square and angle block gauge and jack or support facility etc.Face plate is generally made of cast iron, and working surface passes through through fine finishining such as plane or scrapings, as datum plane during line.The usual horizontal positioned of face plate, scriber is used for ruling bar on workpiece; Tosecan is used for ruling or the centering location of workpiece; Vernier height gauge is used for measuring and line; Plan for drawing circle and circular arc, decile line segment, decile angle and measuring size; Angle square is commonly used for the steering tool drawing vertical line or parallel lines, also can be used to the upright position of centering workpiece planarization on face plate; Angle block gauge is used for drawing angle line.The selection principle of scribe fiducials selects the plane of workpiece, symmetrical centre face or line, important process face as scribe fiducials usually.Generally select the larger plane on part, end face, bottom surface as scribe fiducials face when being wherein benchmark with plane; For symmetrical component, general its symmetrical centre face or the symmetrical center line selected is as scribe fiducials.
But traditional scribble method exists certain not enough, namely directly cannot obtain data when measurement space point, line or plane, can only pass through Reference Transforming indirect inspection, therefore measurement or line precision can not ensure.Especially show to relatively large, highly high, length is large, or when the line of revolution class many space multistories heteromorpha workpiece is measured, as the measurement of the distance of large-scale workpiece along its length between each vertical plane; The highly high ymmetry center plane of symmetry classes part and the measurement of the perpendicularity of ground level; The measurement of the perpendicularity of non-vertical planes symmetrical center line and baseplane, the aspects such as the measurement of the relative angle that slewing parts is each, traditional scribble method is measured inconvenient, and for large-scale workpiece because the error of blank manufacture, in scratching process, need measurement repeatedly, adjustment, borrow multiple operations such as material, again measurement, therefore difficulty of ruling is large, and efficiency is low, poor accuracy.Relevant issues all once proposed in various kinds of document, as " the solid line analysis of key points of large-scale workpiece " (" modern enterprise education " the 4th phase author: Liang Dianmin in 2008), " brief talking large-scale line problem " (" Hunan agricultural machinery: scholarly edition " the 2nd phase in 2008, author: Bi Cuili), " once settled the solid of complicated tank body blank rule simple analysis " (" the scientific and technological world " the 23rd phase in 2012, author: Zhao Zhonggang).
