Abstract

The invention relates to a device for measuring a taper hole, which is composed of a base (2), a slide rod (5), a slide core (8), a contact (1) and a dial indicator (6), wherein the contact (1) is installed in a hole at the lower end of the slide rod (5) and the slide core (8) is installed in the slide rod (5); the dial indicator (6) is installed at the upper end of the slide rod (5) through an expansion ring (10); a locking screw (4) on the slide rod (5) is used for limiting a mutual position of the slide core (8) and the slide rod (5); the contact (1) is reliably contacted with the slide core (8) by springs (7 and 9) in the slide rod (5); the slide rod (5) is installed in the middle of the base (2) and the slide rod (5) can be observed from a window (3) on the side surface of the base (2); scales are arranged on the window (3) of the base and the slide rod, and a vernier depth gauge is formed by the base (2) and the slide rod (5). According to the device, the requirements on the measurement precision of the taper hole can be met and the requirements on an operator are not high; and the device provided by the invention can be used in a process after machining and a machining process, and has the characteristics of wide adaptability, convenience for manufacturing and the like.

Description

technical field [0001] The invention relates to the technical field of mechanical component detection, in particular to a tapered hole measuring device. Background technique [0002] Conical fits are widely used in machine construction and mechanical design. The main reason is that the inner cone hole and the outer cone have the advantages of high coaxiality, good sealing performance, stable self-locking performance, free adjustment of clearance and interference, etc. [0003] However, since the shape of the inner cone and the outer cone are conical, and there are often rounded corners at the end of the cone, this brings inconvenience to processing and testing, especially the measurement work, which is more complicated than cylindrical measurement. Such as figure 1 , is a common marking method for taper hole structures, in which the diameter of the large end D, the height of the cone H, and the cone angle α are important design parameters and values ​​that often need to be...
