Three-coordinate measuring method and measuring device for clamping block parts

Abstract

The invention discloses a three-coordinate measurement method and device for clamp block type parts. The device comprises a bottom plate, a measurement reference block, a measurement reference hole, a measurement reference surface, a left clamp, a right clamp, a left pressure head, a right pressure head, a clamp block disposing step surface, a clamp block disposing arc surface and a column block, wherein the bottom plate and the measurement reference block are connected through an inside hexagonal bolt, the top surface of the measurement reference block is provided with the measurement reference surface, the measurement reference surface is provided with the measurement reference hole, the bottom plate and the column block are connected through an inside hexagonal bolt, the left clamp and the right clamp are connected with the column block through an inside hexagonal bolt, the left clamp is provided with the left pressure head, the right clamp is provided with the right pressure head, the top surface of the column block is provided with the clamp block disposing step surface and the clamp block disposing arc surface, and the clamp block disposing step surface is connected with one end of the clamp block disposing arc surface. The device is advantaged in that measurement reliability is guaranteed under the condition of a single product and small-batch production, the mounting, fixing and measurement time is shortened, detection efficiency is improved, and cost is substantially reduced.

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to a three-coordinate measurement method and a measurement device for clamping block parts. Background technique [0002] When using a three-coordinate measuring machine to detect clamping block R620.3 parts, the current method encounters the following measurement problems: 1) The design reference specified in the drawing is not suitable for the measurement reference, resulting in unreliable reference; 2) The installation is not fixed during measurement. Reliable, the shape of the whole part is a part of a ring, and the surface is coated with a layer of anti-cold welding lubricating film, and the coating on the surface of the part cannot be damaged during installation and measurement; 3) The data obtained by the existing measurement scheme is highly discrete; 4) It is impossible Establish a part coordinate system, and the detection efficiency is low. Due to the above four point...
