Embodiment Construction

[0009] As shown in the figure, at both ends of the two longitudinal seat plates 6 are equipped with horizontal connecting support rods 5, the seat plate 6 and the connecting support rods 5 form a square base; in the middle of the seat plate 6 is equipped with a horizontal rotating shaft 7 to rotate The two ends of the shaft 7 are respectively equipped with a vertical rotating arm 1, the upper end of the rotating arm 1 is equipped with a horizontal detection rod 2, and the middle of the detection rod 2 is equipped with a dial indicator 3.

[0010] When in use, first put the tested piece 4 under the detection rod 2, put the two ends of the tested piece 4 on the connecting support rod 5, and adjust the dial indicator 3 so that the meter head is aligned with the reasonable position of the tested piece 4 . If it is to detect the degree of curved surface, turn the rotating arm 1 longitudinally, and according to the movement of the pointer on the dial indicator 3, read the error value o...

Abstract

The invention provides a curved surface radian and straightness detecting device, and is characterized in that transversal connecting support rods are arranged on two ends of two longitudinal seat plates, wherein a square base is formed by the seat plates and the connecting support rods; a transversal rotational axis is arranged on the middle of the seat plates, longitudinal rotational arms are arranged on both ends of the rotational axis respectively; and a transversal detecting rod is arranged on the upper ends of the rotational arms, wherein a dial gauge is arranged on the middle of the detecting rod. According to the radian and straightness detecting device, the problems that the low efficiency of the traditional straightness and curved surface radian and inaccuracy are solved, and thecurved surface radian and straightness detecting device is widely used in the detection of the curved surfaces with the curved surface radian requirement and the straightness requirement.

Description

Technical field [0001] The invention relates to the field of quality inspection of machined parts, in particular to a special instrument for detecting the radian and straightness of a workpiece. Background technique [0002] The traditional straightness detection method is carried out with a knife-edge ruler and a feeler gauge, and no specific value can be measured, but an estimated value. There are two methods for detecting the degree of curved surface. One is to rotate the workpiece to read the stopwatch, and the other is to use three-dimensional coordinates, which is more difficult. As for the curved surface that has both curved surface and straightness requirements, the inspection is very troublesome and the efficiency is low. Summary of the invention [0003] In order to solve the problems of low efficiency and inaccuracy of traditional straightness and curved surface detection methods, the present invention invents a special device that can detect both straightness and curv...
