Abstract
The utility model relates to a magnetic absorbing French curve, consisting of a tightening screw, a supporting pole, a bracket board, a column-shaped surveying pin, an eyelet, a magnetic material and a semi-circle groove. The bracket board is connected by the tightening screw through the supporting pole, and the magnetic material is absorbed on the bracket board and the magnetic force is transmitted to the end face of the bracket board. By the adjustment to the distance between the magnetic material and the end face of the bracket board, the magnetic absorbing force of the end face can be adjusted. The column-shaped surveying pin is absorbed on the end face of the bracket board, and the semi-circle groove is arranged at the end face of the bracket board to prevent the column-shaped surveying pin from rolling on a bracket. The utility model can be applied to the surveying and plotting to a curve face, a mould and a working piece with better stability and easy operation.
Description
Affiliated technical field
The utility model relates to a kind of survey instrument that is used to measure irregular curved surface, mould, workpiece etc.
Background technology
At present the survey instrument that uses is: cylindrical chaining pin is by two metal clips together, have that cylindrical chaining pin easily moves, poor stability, can not curve plotting, defective such as complicated operation.
Summary of the invention
In order to overcome deficiencies such as poor stability that existing survey instrument exists, complicated operation, the utility model provides a kind of magnetic attached curve gauge, and this instrument utilizes the attached principle of magnetic that cylindrical chaining pin is adsorbed on the support, is convenient to measurement and drawing to curved surface.
The technical scheme that its technical matters that solves the utility model adopts is: the attached curve gauge of a kind of magnetic is made up of holding screw, pole, supporting plate, cylindrical chaining pin, eyelet, magnetic material, half slot, supporting plate is connected by holding screw by pole, magnetic material is adsorbed on the supporting plate, and with the end face of magnetic conductance at supporting plate, adjust the distance of magnetic material from the end face of supporting plate, can adjust the magnetic attraction of end face, cylindrical chaining pin is attracted on the end face of supporting plate, the end face of supporting plate has semi-circular groove, prevents that cylindrical chaining pin from rolling on support.
The utility model is good stability when measurement that is used for curved surface, mould, workpiece and drawing, and is simple to operate.
Description of drawings
