Oblique geometric tolerance measuring instrument

Abstract

The invention discloses an oblique geometric tolerance measuring instrument, which comprises a base (1), a three-jaw chuck (13), a guide rail (15), a thimble (16), a rotating guide rail (29), and a column (52) and measuring platform (41), guide rail (15) and rotating guide rail (29) are installed on the base (1), three-jaw chuck (13) and thimble (16) are respectively installed on the two ends of guide rail (15), and rotating guide rail (29 ) on which the column (52) and the rotating chassis (30) are installed, the measuring platform (41) is installed on the column (52), the measuring platform (41) is equipped with the No. 1 measuring rod (68) and the No. 2 measuring rod (59), one The small end of the No. 1 measuring head (67) is vertically sleeved in the hole at the end of the No. 1 measuring rod (68), and the No. 2 measuring head (62) is installed on the No. 2 measuring rod (59) at 90 degrees, forming an oblique geometry as a whole. Tolerance measuring instrument. The invention has a simple and reliable structure, and is easy to operate. The rotating guide rail drives the measuring head to move along a straight line or an oblique line, and is suitable for measuring most oblique geometric tolerance feature items.

Description

technical field [0001] The invention relates to a measuring instrument, in particular to an oblique geometric tolerance measuring instrument. Background technique [0002] In the geometric tolerance measurement of mechanical parts, the measurement of oblique geometric tolerance feature items is often encountered, that is, the measured geometric elements are oblique relative to the part body, or the measured elements are inclined at a certain angle relative to the reference elements, such as inclined planes, Oblique line, conical occurrence line, inclination, oblique runout, etc. When measuring, the position of the part or the track of the dial indicator must be adjusted to meet the requirements of the inclination. The measurement process is complicated, the accuracy is poor, the efficiency is low, and even the measurement process cannot be implemented. Contents of the invention [0003] The object of the present invention is to design an oblique geometric tolerance measuri...
