Abstract

The invention relates to a special gauge for coning, in particular to a special angle gauge for outer cone, which comprises a guide bar, a main scale plate, an auxiliary scale plate, an upper measuring tape and a lower measuring tape. The guide bar is 'L'-shaped and formed by the connection of a cross bar and a vertical bar. One end of the cross bar is equipped with the lower measuring tape. The vertical bar is sheathed with a guide block of which one end face is fixedly connected with a connecting board and another end face parallel to the connecting board is provided with a pressing block. The central hole of the pressing block is provided with a first pin roll of which another end is provided with thread. The thread end is externally sheathed with a first lock nut. Another end of the connecting board is fixed with the main scale plate and a second pin roll is embedded in the central hole of the main scale plate. The auxiliary scale plate neighboring the main scale plate is sheathedon the central part of the second pin roll. The extending end of the second pin roll is provided with thread on which a second lock nut is sheathed. The lower part of the auxiliary scale plate is provided with the measuring tape. Compared with the prior art, the special angle gauge for outer cone has the advantages of convenient measurement, less time consumption and accurate measuring results.

Description

Technical field: [0001] The invention relates to a special measuring tool for tapers, in particular to a special protractor for external cones. Background technique: [0002] In mechanical equipment, shaft parts with conical surfaces are often used. For such parts with high precision and surface roughness requirements, in addition to being processed by CNC lathes, they are generally turned on ordinary lathes first, and left Grind the allowance and then grind on an external grinding machine. The method of processing the conical surface on the lathe is to rotate the small tool holder by a corresponding angle. The method of grinding the conical surface on the grinding machine is to rotate the table by a corresponding angle. The scale on the lathe tool holder and the scale on the grinder table are very inaccurate and can only be used as a reference. In the processing process, according to the actual taper of the workpiece, if you want to process a qualified conical surface, y...
