Description
Technical field
The present invention relates to pressing machine production, manufacture field, particularly relate to the improvement of the collection of the motion state to bent axle in pressing machine, the device of monitoring.
Background technology
Usually a rotary encoder is connected on the bent axle of pressing machine in prior art, thus the real-time position information of bent axle is gathered, monitored, the portion " monitoring device for angle of pressure machine bent axle " by name applied on Dec 12nd, 2008 as the applicant, application number are the document of " 200820215139.8 ".But, due to pressing machine work time, on bent axle will produce very high frequency low amplitude vibration; Now, as being directly connected on bent axle by rotary encoder, great damage will be brought to rotary encoder, thus have a strong impact on collection to crank position information, monitoring, and great impact will be brought on the serviceable life of rotary encoder.
Summary of the invention
The present invention is directed to above problem, propose a kind of delicate structure, while effectively avoiding, because of crankshaft vibration, infringement is produced to rotary encoder, the crankshaft angles monitoring device still gather by the real-time position information of rotary encoder to bent axle, monitored.
Technical scheme of the present invention is: described bent axle is connected in the frame of pressing machine, and described angle monitor device comprises mount pad, rotary encoder, transmission shaft, axle bed and shaft coupling;
Described mount pad is connected in described frame, described rotary encoder and axle bed are fixedly connected on the end face of described mount pad, described transmission shaft is located in described axle bed, and one end of described transmission shaft is connected with described rotary encoder and the other end is connected with described bent axle by described shaft coupling;
Described shaft coupling comprises contiguous block one, connecting link and contiguous block two, described contiguous block one is fixedly connected on described transmission shaft away from one end of described rotary encoder and contiguous block one offers vertical through hole one, and described contiguous block two is fixedly connected on described bent axle towards one end of described transmission shaft and contiguous block two offers vertical through hole two; The two ends of described connecting link are respectively equipped with U-shaped opening one and opening two, are fixedly connected with the vertical latch one with described vertical through hole one adaptation in described opening one, are fixedly connected with the vertical latch two with described vertical through hole two adaptation in described opening two.
Described connecting link is telescopic rod.
Described mount pad is connected on the column of frame by horizontally disposed spring base, described spring base comprises guide rod, installing plate and spring, described guide rod is horizontally disposed with and is fixedly connected on column, described installing plate is socketed described guide rod, the bottom of described mount pad is fixedly connected on described installing plate, and described spring is socketed described guide rod and between described installing plate and column.
When the present invention uses, first contiguous block one and contiguous block two can be stretched in opening one and opening two respectively, more vertical latch one is inserted in vertical through hole one and vertical through hole two respectively with vertical latch two, and complete with opening two with opening one respectively and be fixedly connected with; When producing the micro-dither in short transverse like this when bent axle, vibration can be consumed in the moving up and down of connecting link, and not import transmission shaft into; Simultaneously, because vertical latch one is with vertical through hole one, be fitting relation between vertical latch two and vertical through hole two, therefore, the micro-dither producing horizontal direction when bent axle is, vibration can be consumed in the relative rotary motion of connecting link and transmission shaft, also can not import transmission shaft into; In addition, because transmission shaft is located in axle bed, therefore friction on rotary encoder can be guaranteed further.
Comprehensively above-mentioned 3 points, this case can effectively avoided producing infringement (no matter along the vibration of short transverse or the vibration of horizontal direction because of crankshaft vibration to rotary encoder, all can realize " omnidirectional's antivibration ") while, still gather by the real-time position information of rotary encoder to bent axle, monitor.There is Stability Analysis of Structures, good reliability, DATA REASONING feature accurately.
Accompanying drawing explanation
