It is co-axially mounted a detection table, the detector of the detection table is located in the axis hole of outer sleeve；It is coaxially set in the axis hole of outer sleeve
An elastic telescopicing rod is set, the upper end of the elastic telescopicing rod presses against on the detector of detection table, and the lower end of elastic telescopicing rod is prolonged
Extend to the lower section of the bottom surface of outer sleeve.
Moreover, an annular erecting bed is coaxially produced on the top of the shaft hole inner wall of the outer sleeve, elastic telescopicing rod by
The body of rod and spring are constituted, and the upper outside of the body of rod coaxially produces annular convex platform, in annular convex platform placement and annular erecting bed, In
Coaxial package spring on the body of rod above annular convex platform.
Moreover, the outer diameter of the elastic telescopicing rod matches with the internal diameter of central hole of the crankshaft to be detected, elastic telescopicing rod
Lateral wall and housing medial wall of the tube between gap match with the wall thickness of crankshaft to be detected.
Moreover, a downward opening blind hole is coaxially produced in the axle center of the elastic telescopicing rod.
The advantages and positive effects of the utility model are as follows:
1, the present apparatus is mainly made of outer sleeve, elastic telescopicing rod, mounting base and detection table, the bottom surface and song of outer sleeve
The annular groove of axial end contacts positioning, the inner bottom surface positioning of elastic telescopicing rod and central hole of the crankshaft, the displacement of elastic telescopicing rod
Amount can be obtained by detection table, which is numerical value to be measured.Present apparatus use is very simple and convenient, and testing result is accurately straight
It sees, can fast and accurately judge whether workpiece meets the requirements, avoid erroneous judgement phenomenon from occurring, substandard product is avoided to flow out.
2, present apparatus operation is convenient, and staff is easily mastered, and detection efficiency can be greatly improved after use.
3, present apparatus structure is simple, easy to manufacture and at low cost, not will increase the cost of enterprise.
4, the utility model be a kind of design rationally, scientific structure, easy to use, practical be exclusively used in detection crankshaft
The device of depth can reduce detection difficulty using the present apparatus, the accuracy for improving detection, quickening detection speed, meet client
Demand.
