Contact type normal measuring device

Abstract

The invention discloses a contact type normal measuring device. The contact type normal measuring device is characterized in that the measuring device comprises a shell (1), a spherical surface base body (2) is movably connected with the lower portion of the shell (1), the spherical surface base body (2) is in spherical surface connection with the shell (1), three arc-shaped pressure angles (3) which are evenly distributed on the circumference are arranged at the lower end of the spherical surface base body (2), an induction flange (4) is fixedly arranged at the upper end of the spherical surface base body (2), a plurality of position sensors (5) matched with the induction flange (4) are arranged in an inner cavity of the shell (1), a reset spring (6) is further arranged on the lower end face of the induction flange (4), and a circle center hole (7) of the shell is communicated with a machined hole (8) of the spherical surface base body (2). According to the contact type normal measuring device, the normal of a large-curvature thin-wall workpiece can be fast and accurately found.

Description

technical field [0001] The invention relates to a measuring device, in particular to a contact-type normal direction measuring device. Background technique [0002] When processing thin-walled workpieces with large curvature, it is often necessary to find the normal of the curved workpiece first, and then perform drilling and other processing activities along the normal. In order to accurately find the normal of such workpieces, there are many search methods However, most of these devices are simple in structure and complicated to operate, and some of them need to be operated repeatedly and corrected many times to find the normal line, which is extremely inefficient and the accuracy of the obtained normal line is also poor. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned deficiencies in the prior art, and propose a contact-type normal measuring device capable of quickly and accurately finding the normal of a large-cur...

[0002] When processing thin-walled workpieces with large curvature, it is often necessary to find the normal of the curved workpiece first, and then perform drilling and other processing activities along the normal. In order to accurately find the normal of such workpieces, there are many search methods However, most of these devices are simple in structure and complicated to operate, and some of them need repeated operations and repeated calibrations to find the normal line. The efficiency is extremely low, and the accuracy of the normal line obtained is also poor.
