Description
Technical field
The utility model relates to a kind of endoporus coaxiality check fixture, belongs to the pick-up unit field.
Background technology
At present in China's mechanical processing industry, right alignment is to measure the larger a kind of location parameter of difficulty, particularly the size of measured hole is larger, it is very high highly again, as the motor casing of generator and huge revolving circular piece etc., when throughput rate is very high, the surveying work amount will be very large, add that tested size is large, the Quick Measurement that will realize in this case inter process is a difficult problem really.Although utilize the exact instrument in measuring room, as by means of the very strong three coordinate measuring machine of versatility, also can complete this detection, this kind method cost is high, and measuring speed is relatively also slow, is not suitable for the higher workshop use of production efficiency.At present, the mode that is used for the measurement of inner hole of workpiece right alignment inter process mainly contains receiver ga(u)ge and reading type pick-up unit two classes, though the former has easy to use, the advantage that work efficiency is high, but mostly can only be used for miniature workpiece, except with the large-scale detecting instruments such as three-dimensional, there is no the measurer of direct-detection measuring for the coaxiality error, particularly some size is also restricted on three-dimensional.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of simple in structure, easy to use, and cost-saved endoporus coaxiality check fixture.
The utility model is that the technical scheme that its technical matters of solution adopts is: described endoporus coaxiality check fixture, it is characterized in that: comprise base, the bottom of base arranges two locating shafts, one side of base arranges the dial framework seat, dial framework vertically is installed on the dial framework seat, measurement instrument is installed on dial framework, pass base and the dial framework seat arranges connecting link, connecting link and dial framework seat are positioned at the same side of base, and slip positioning support bracer is set on connecting link.
Two locating shafts play the effect of detection and localization together with slip positioning support bracer; The dial framework seat is used for connecting dial framework, and dial framework is used for installing and measuring instrument; Connecting link is used for supporting slip positioning support bracer.
Described dial framework is fixed by screws on the dial framework seat, and connecting link is fixed by screws in respectively on base and dial framework seat, and slip positioning support bracer is fixed by screws on connecting link.Above-mentioned parts are connected and fixed by screw respectively, can with screw loosening, dial framework seat, connecting link and base be moved up and down simultaneously along dial framework according to the needs of measuring workpieces, and slip positioning support bracer can be moved left and right along connecting link.
The beneficial effects of the utility model are:
Simple in structure, easily realize; The dial framework seat, dial framework, slip positioning support bracer and the measurement instrument that arrange can be measured the endoporus right alignment fast and accurately, can increase work efficiency, and simple and practical, applicability is strong.
