Embodiment Construction

[0012] figure 1 It is a structural schematic diagram of the present invention, including a handwheel 1, an inner cone 2, an outer cone 3, a handle 4, a rotary table 5 and a dial indicator 6, and the inner cone 2 is assembled in the inner cone hole of the outer cone 3 , the outer cone 3 is made of spring steel and has eight grooves on the side, so when the inner cone hole is stressed, it has the function of expanding outward. The top of the outer cone 3 is provided with a rotary table 5 with bearings. A dial gauge is provided, the handwheel 1 is connected to the inner cone 2 and the outer cone 3, and the outer cone 3 is also provided with a handle 4.

[0013] In actual operation, two hands hold the handle 4 and place the detection device as a whole into the inner hole of the workpiece 7, then rotate the hand wheel 1 to force the inner cone 2 to move inward axially, and at the same time, the outer cone is The outer circle of the cone 3 expands, thereby eliminating the gap betwe...

Abstract

The invention relates to the technical filed of detection devices, in particular to a detection device of inner hole coaxiality of a large disc type workpiece. The detection device of the inner hole coaxiality of the large disc type workpiece comprises a hand wheel, an inner conical piece, an outer conical piece, a handle, a rotary table and a dial indicator, wherein the inner conical piece is assembled in an inner conical hole of the outer conical piece; the rotary table provided with a bearing is arranged at the top of the outer conical piece; the dial indicator is arranged on the rotary table; and the hand wheel is connected with the inner conical piece and the outer conical piece. The detection device of the inner hole coaxiality of the large disc type workpiece is simple in structure, easy to operate, high in measurement accuracy and low in measurement technical requirement, and can realize real-time detection.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection device for the coaxiality of the inner hole of a large disk type workpiece. Background technique [0002] In the existing technology, it is difficult to detect the coaxiality of the inner hole of large disc workpieces. The problems in the existing technology are that the detection technology is high and the detection timeliness is poor, especially the lack of effective inspection equipment on the relevant stations of the production line. Real-time detection, the problem of detection lag is easy to cause batch scrapping, resulting in unnecessary waste and reducing production efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is: it is relatively difficult to detect the coaxiality of the inner hole of a large disc-like workpiece, and a device for detecting the coaxiality of the inner hole of a large disc-like workpiece is pr...
