Description
Technical field
The utility model relates to that pressing machine is produced, manufacture field, relates in particular to the improvement of the device of collection, the monitoring of the motion state to bent axle in pressing machine.
Background technology
In prior art, conventionally a rotary encoder is connected on the bent axle of pressing machine, thereby the real-time position information to bent axle gathers, monitors, if the applicant is the document of " 200820215139.8 " in portion " monitoring device for angle of pressure machine bent axle " by name, the application number of application on Dec 12nd, 2008.But, while work due to pressing machine, on bent axle, will produce the very low amplitude vibration of high frequency; Now, as directly rotary encoder being connected on bent axle, will bring great damage to rotary encoder, thereby have a strong impact on collection, monitoring to crank position information, and on having brought great impact the serviceable life of rotary encoder.
Utility model content
The utility model is for above problem, a kind of delicate structure has been proposed, in effectively avoiding, because of crankshaft vibration, rotary encoder is produced to infringement, the crankshaft angles monitoring device that still can the real-time position information of bent axle be gathered, be monitored by rotary encoder.
The technical solution of the utility model 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 offering vertical through hole one on one end of described rotary encoder and contiguous block one, and described contiguous block two is fixedly connected on described bent axle and offers vertical through hole two on one end of described transmission shaft and contiguous block two; The two ends of described connecting link are respectively equipped with U-shaped opening one and opening two, are fixedly connected with and the vertical latch one of described vertical through hole one adaptation in described opening one, are fixedly connected with the vertical latch two with described vertical through hole two adaptations in described opening two.
Described connecting link is telescopic rod.
Described mount pad is connected to by horizontally disposed spring base on the column of frame, 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 utility model uses, can first contiguous block one and contiguous block two be stretched into respectively in opening one and opening two, again vertical latch one is inserted respectively in vertical through hole one and vertical through hole two with vertical latch two, and complete and be fixedly connected with opening two with opening one respectively; Like this in the time that bent axle produces the micro-dither in short transverse, vibration can be consumed in the moving up and down of connecting link, and not import transmission shaft into; Simultaneously, be fitting relation due between vertical latch one and vertical through hole one, vertical latch two and vertical through hole two, therefore, when the micro-dither of bent axle generation horizontal direction 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 can further guarantee friction on rotary encoder.
Comprehensive above-mentioned 3 points, this case can effectively avoid, because of crankshaft vibration, rotary encoder is produced to infringement (no matter along the vibration of short transverse or the vibration of horizontal direction, all can realize " omnidirectional's antivibration ") time, still can the real-time position information of bent axle be gathered, be monitored by rotary encoder.There is Stability Analysis of Structures, good reliability, DATA REASONING feature accurately.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the A place partial enlarged drawing of Fig. 1;
In figure, 1 is bent axle, the 2nd, and frame, the 3rd, mount pad, the 4th, rotary encoder, the 5th, transmission shaft, the 6th, axle bed, the 7th, shaft coupling, the 71st, contiguous block one, 72nd, contiguous block two, 73rd, connecting link, the 731st, vertical latch one, 732nd, vertical latch two.
