Description
Technical field
The utility model relates to the laboratory to be used device for measuring force is detected and the calibration technique field, particularly relates to a kind of proof force source generating apparatus that can produce 0-200 thousand newton.
Background technology
Along with the rapid economic development and the science and technology of China are constantly progressive, every profession and trade is more and more higher to the measuring requirement of power value.As the instruments such as sensor, LOAD CELLS and proving ring of ergometry, all needing to detect demarcation in the laboratory can come into operation.The proof force source that common laboratory is used is that hydraulic systems such as hydraulic jack or hydraulic jack produce.The shortcoming of these proof force source generating apparatus is power output instabilities, need revision test relatively, efficient is low, the proof force that produces is limited in scope, the arbitrarily output of established standards power, proof force source apparatus self uses inconvenient, is easy to generate the hydraulic seal leakage problem in use, has restricted the progress of measurement technology greatly.
The utility model content
The technical problems to be solved in the utility model, provide the output of a kind of proof force accurately and power output stable, the proof force source generating apparatus that the proof force output area is wide.
The technical scheme that adopts is:
A kind of proof force source generating apparatus comprises frame, operator's console, last support body, following support body, servomotor, driver, reductor, seaming chuck, push-down head, leading screw screw pair, pressure transducer and computing machine.Described last support body connects following support body and is an one-piece construction, and last support body and following support body are fixedly connected on the frame.Servomotor is contained on the frame, the servomotor output shaft connects the reductor input shaft, speed reducer output shaft connects leading screw one end of leading screw screw pair, the leading screw other end is connected with push-down head, between push-down head and the following support body pressure transducer is housed, seaming chuck is fixed on the support body and is corresponding with push-down head.Described operator's console is equipped with computing machine and driver, and actuator electrical connects servomotor, and computing machine and pressure sensor signal connect and compose close loop control circuit.
The utlity model has easy to usely, can export one accurately and stable proof force, be adapted at producing the proof force source in the laboratory, dynamometer is detected and demarcates.
