Abstract

The invention discloses a coaxiality measuring device and method for a large-span shaft hole part. The device comprises: an axis alignment mechanism installed on to-be-detected parts and used for aligning the axis of a hole or a shaft part; a laser source part used for emitting a reference laser beam coinciding with the axis of the hole or the shaft part at one side; and a position display part used for receiving the laser and measuring the coaxiality of the two to-be-detected parts according to the position of the reference laser spot. According to the embodiment of the invention, the laser source part and the position display part are used for detecting the coaxiality of the to-be-detected parts, the structure is simple, and the cost is low; one set of coaxiality measuring devices can besuitable for coaxiality inspection of to-be-detected parts of various hole shafts with different diameters; and moreover, the laser propagation linearity is good, and the coaxiality measuring deviceand method are especially suitable for coaxiality measurement of large-span shaft hole parts.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to a device and method for measuring the coaxiality of large-span shaft-hole components. Background technique [0002] For the manufacturing industry, quality is always the lifeline of an enterprise. There are generally various coupling mechanisms in mechanical equipment. In order to ensure the linkage of coaxial lug plates or lug seats, it is necessary to increase their coaxiality requirements during the manufacturing process. At present, in order to ensure the coaxiality of the coaxial lug plate or lug seat, the process axis is generally used to guarantee it. The process axis scheme has the following problems: first, the manufacturing process of the process axis is difficult; second, it is difficult to guarantee the straightness and coaxiality of the process axis itself with a large span; Craft axis, poor versatility. For the coaxiality detection of long-span lugs o...
