A detection tool for large-diameter external conical surface

Abstract

The invention relates to a large-diameter outer circular conical surface detection tool, which comprises a fixed clamping plate, a fixed magnet block, a supporting block, a reference measurement column I, a reference measurement column II and a base, and is characterized in that the middle of the base is hollow U-shaped, two sides of the base are rectangular plates, a V-shaped structure is formed between the plates, the base is fixed on between two circumferential surfaces, whose diameter is required to be measured, of the side surface of a circular truncated cone workpiece through the plates at the two ends; the supporting block is of a concave structure and located inside the V-shaped structure of the base, a notch is contacted with the circular truncated cone side surface, and the top end is clamped with the U-shaped structure of the base. The beneficial effects of the technical scheme provided by the invention are that a special detection tool is designed according to the workpiece to be processed, the precision of taper detection is improved, and a problem of inaccurate measurement caused by machine precision, personal operations and the like in early taper detection is avoided; detection can be carried out on the diameter and the taper of a circular conical surface quickly, and the detection efficiency is improved; and measurement can be carried out in real time in the processing process, and the quantitative accuracy in processing is ensured.

Description

technical field [0001] The invention relates to the field of tooling, in particular to a tooling for detecting the diameter and taper of a large-diameter outer cone. Background technique [0002] In the past, when machining conical surfaces, it was difficult to measure the diameter and taper, and the accuracy of the measurement could not be guaranteed. Small-diameter tapers are usually tested with special constant taper ring gauges. The method of ring gauge detection has great limitations on large-diameter workpieces, so large-diameter cones usually use the method of reserving a straight section at the starting position of the cone surface, or welding a reference block at the starting position of the cone surface. Measure the diameter of a straight section or reference block to indirectly measure the diameter of the cone. Taper measurement usually adopts the method of adding a dial indicator on the machine tool, and calculates the change in the direction of the radius of th...

Problems solved by technology

However, the entire machining and measurement process is relatively complicated, the efficiency is low, and it is greatly affected by the accuracy of the machine tool, so the accuracy of the measurement cannot be guaranteed.

[0003] The common technology for detecting taper is to use taper gauge to detect the cone, that is, to make an opposite inner cone inspection tool according to the taper of the cone surface, and use the nesting method to qualitatively detect the taper. This method can only be used as a verification method for taper processing. , cannot reflect the specific value
