Although the sine gauge can measure the readings of the bevel gear bevel surface, the same reference is required during the measurement, that is, the same micrometer needs to be used to move from one end of the bevel surface to the other end, which is extremely easy to cause the measurement error during the movement process. The installation position of the micrometer changes, which makes the measured data error larger
Moreover, the sine gauge does not have a special fixture for installing the bevel gear, which makes it difficult to ensure that the bevel gear is installed in the correct position

Abstract
The invention discloses a detecting instrument, particularly discloses a face cone measuring tool of a conical gear, and provides a face cone measuring tool of the conical gear, which can reduce measurement errors. The face cone measuring tool comprises a sine bar formed by a bottom plate, a measuring block, an object placing plate, a front cylinder and a back cylinder; the measuring block is vertically placed on the bottom plate; the back cylinder is placed on the bottom plate; the front cylinder is placed on the measuring block; the object placing plate is placed on the front cylinder and the back cylinder; a right-angled triangle is formed by the object placing plate, the measuring block and the bottom plate; the face cone measuring tool further comprises at least two dial indicators and a zero calibrating block; the zero calibrating block is arranged on the bottom plate; and the upper surface of the zero calibrating block is parallel to the upper surface of the bottom plate. As the dial indicators are firstly calibrated to zero before the measurement, that is, the dial indicators are adjusted to zero positions by utilizing the zero calibrating block, and then the dial indicators are utilized to simultaneously measure parts of the face cones of the conical gear, the difference value between the dial indicators is equal to the deviation.
Description
technical field [0001] The invention relates to a detection instrument, in particular to a bevel gear face cone measuring tool. In addition, the invention also relates to a detection method of the face cone angle error and a measurement method of the face cone intersection point. Background technique [0002] After the bevel gear is processed, it is necessary to detect the angle of the face cone of the bevel gear and the intersection point of the face cone. The intersection point of the face cone is the distance between the intersection point of the face cone and the reference plane. In order to judge whether the bevel gear is qualified. The traditional detection method is to make a face cone clamp. The face cone clamp has a trapezoidal notch. This gap is exactly the standard bevel gear face cone angle. Therefore, as long as the face cone clamp can match the bevel gear cone surface, the surface The face cone angle of the bevel gear is qualified. However, during the operat...
