Embodiment Construction
[0008] Such as figure 1 As shown: 1 is the working platform, on which there is a moving seat 11, the moving seat 11 is connected to the driving mechanism, the driving mechanism is the servo motor 2, and the ball screw nut moves between the moving seat 11 and the servo motor 2 Way, that is, the output shaft of the servo motor is connected to the ball screw 12 through the deceleration part, and the screw nut matching the ball screw 12 is fixed on the moving seat 11 . Servomotor 2 can drive movable seat 11 to move linearly when servomotor 2 acts. On the moving base 11, a pressure sensor 5 is installed through the mounting base 6, one end of the pressure sensor 5 is connected to the connecting plate 7, and the other end is connected to the signal processing system, the signal processing system is a signal amplifier 4 connected with the pressure sensor 5 and a drive mechanism That is, the numerical control system 3 connected with the servo motor 2 . Connecting plate 7 is connecte...

The invention discloses a digitalization surface normal measuring system which comprises a working platform, a shifting seat is arranged on the working platform, the shifting seat is connected with driving mechanisms, pressure sensors are installed on the shifting seat through an installation seat, the pressure sensors are connected with a connection plate and a signal processing system, a locating pin is connected on the connection plate, the axis of the locating pin is in line with the shifting direction of the shifting seat, and a ball head is connected at the front end of the locating pin. When the digitalization surface normal measuring system is used, the shifting seat can be driven to shift in a linear mode through the servo motors, meanwhile, the installation seat, the sensors, the connection plate and the locating pin shift simultaneously, so that the ball head at the end of the locating pin is close to a curved surface of a workpiece, after contacting and stressing, force K toward the measuring face can appear on the locating pin, a signal is measured and acquired through the sensors and processed by the signal processing system, and according to signal conversion, the normal direction (angle A) of the measured position on the curved surface can be displayed. The measuring system is simple in integral structure, accurate in measuring, time-saving and labor-saving.
Description
technical field [0001] The invention relates to a measuring mechanism, in particular to a digital curved surface normal measuring system, which is mainly used for measuring the curved surface normal direction of workpieces. Background technique [0002] For the processing of workpieces with curved surfaces, sometimes it is necessary to know the normal direction of the curved surface of the workpiece. Measuring the normal is cumbersome, and most of them are carried out with manual tools. Contents of the invention [0003] The object of the present invention is to provide a digital surface normal measurement system with simple overall structure, accurate measurement, time-saving and labor-saving, so as to overcome the deficiencies of the prior art. [0004] The digital surface normal measurement system of the present invention includes a working platform, on which a moving seat is arranged, the moving seat is connected to a driving mechanism, a pressure sensor is installed o...
