Problems solved by technology
[0003] At present, the flatness of the product profile is measured manually using calipers, and the profile flatness of the product is calculated by multiple sets of measurement data at different positions. This measurement method has large errors and low efficiency. In addition, for curved surfaces On the face of it, this method is extremely inappropriate

The invention discloses a surface evenness measuring instrument, a platform plate capable of height adjustment is arranged on a frame body, one side of a carrier plate is fixedly connected to the frame body, the carrier plate is provided with a strip-shaped through hole along the length direction, a plurality of displacement meters are slidably arranged in the strip-shaped through hole along the length direction of the strip-shaped through hole, and measuring pointers of the plurality of displacement meters are arranged downward and extend out of a bottom end face of the carrier plate; a vertical rod is arranged on a pedestal, a side of the vertical rod facing the platform plate is provided with a vertical strip-shaped groove, a sliding block capable of sliding along the length direction of the strip-shaped groove is arranged on a side wall of the platform plate, and a threaded rod vertically penetrates through a top wall of the strip-shaped groove from above the vertical rod to extendinto the strip-shaped groove and spirally penetrates into the sliding block; and a supporting seat is arranged under the pedestal, and the supporting seat and the pedestal are connected through a telescopic column. The measuring instrument can measure the profile evenness of a relatively large object accurately and rapidly, and is convenient to operate by rising and falling to different heights.
Description
technical field [0001] The invention relates to a detection instrument, in particular to a measuring instrument for surface flatness. Background technique [0002] At present, due to the needs of product quality itself, the flatness of the product profile is an important indicator for product quality evaluation, such as glass profile, steel plate profile, etc. [0003] At present, the flatness of the product profile is measured manually using calipers, and the profile flatness of the product is calculated by multiple sets of measurement data at different positions. This measurement method has large errors and low efficiency. In addition, for curved surfaces On the face of it, this method is extremely inappropriate. Contents of the invention [0004] The object of the present invention is to provide a measuring instrument for surface flatness, which can accurately and quickly measure the profile flatness of larger objects, and is not limited to the measurement of flat prof...
