Example Embodiment

[0013] Such as figure 1 Shown is a structural cross-sectional view of a taper detection device according to the present invention, which mainly includes a mandrel 2, an end plate 3, a movable plate 4, and a top wire 5. The end plate 3 is placed at one end of the mandrel 2 and connected to the mandrel Fixed, the moving disk 4 is perforated in the center, and the bore diameter is slightly larger than the shaft diameter of the spindle 2. It can be sleeved on the other end of the spindle 2 and can slide along the spindle 2, when the moving disk position is locked into the taper hole of the workpiece 1 Then use the top wire 5 to fix the moving plate 4 and the mandrel 2, where the disk surfaces of the end plate 3 and the moving plate 4 should be perpendicular to the mandrel, and the diameter of the moving plate 4 is larger than the diameter of the end plate 3, which can be specified according to actual needs Different specifications are produced, but in order to facilitate the calcul...

Abstract

The invention relates to a taper detection device which comprises a mandrel device, wherein one end of the mandrel of the mandrel device is fixedly provided with an end disk, and the other end of the mandrel can be slidably sheathed in a movable disk the diameter of which is greater than that of the end disk; the movable disk is fixed with the mandrel through top threads; and the end surfaces of both the end disk and the movable disk are perpendicular to the mandrel. When the taper detection device is used for measuring the taper of a taper hole, the difference between the large and small diameters of the taper hole is fixed, thereby greatly reducing the measuring parameters and enhancing the measuring accuracy. The taper detection device provided by the invention is simple in structure and convenient in operation.

Description

technical field [0001] The invention relates to the field of measurement, in particular to a taper detection device. Background technique [0002] In the inspection of mechanical parts, the detection problem of the taper of the inner hole is often encountered. The traditional detection method is to measure the diameter D of the large end, the diameter d of the small end, and the length L of the cone, and then use the formula C=(D-d) / L to calculate Taper C. This method has many measurement parameters, and since the generatrix of the cone is an inclined straight line, there is a large error when measuring the diameter of the large end and the small end, so the calculated taper has low accuracy. Contents of the invention [0003] The object of the present invention is to provide a new type of taper detection device, which has fewer measurement parameters, more convenient operation and higher detection accuracy when using the present invention to measure the taper of the inne...
