Embodiment
Load pick-up unit below in conjunction with embodiment and accompanying drawing to the portable force value of one of the present utility model to be described in detail.
As shown in Figure 1, the portable force value of one of the present utility model loads pick-up unit, for the universal testing machine 1 be made up of base 11 and test rack 12, the lower end of the crossbeam 13 of described universal testing machine 1 is provided with standard dynamometer or the standard transducer 3 of the precision for detecting the tested sensor 2 be fixed on above described crossbeam 13, the ball-screw 5 be connected with described standard dynamometer or standard transducer 3 for driving standard dynamometer or the vertical movement of standard transducer 3, and the driving mechanism 6 be connected with described ball-screw 5 for driving the vertical movement of ball-screw 5.
The base 11 of described universal testing machine 1 is provided with driving mechanism casing 8, described driving mechanism 6 is arranged in described driving mechanism casing 8, and the top of described ball-screw 5 is run through described driving mechanism casing 8 and is connected with described standard dynamometer or standard transducer 3.
Described standard dynamometer or standard transducer 3 can be arranged on pedestal 4, described pedestal 4 is arranged on screw mandrel nut 7, described screw mandrel nut 7 is arranged on described driving mechanism casing 8, and the top of described ball-screw 5 is run through described driving mechanism casing 8 successively and is fixedly connected with described pedestal 4 with screw mandrel nut 7.Screw mandrel nut 7 is wherein for limiting the position of ball-screw 5.Standard dynamometer described in the utility model or standard transducer, can use the product of Tianshui Hongshan Testing Machine Co., Ltd., or use the product of Xi'an Hong Shan surveying instrument company limited.
Described driving mechanism 6 includes servomotor 61, the worm screw 62 that the output shaft of one end and described servomotor 61 is connected to a fixed, be fixedly connected on the mechanical handwheel 63 of described worm screw 62 other end, and the worm gear 64 be connected with a joggle in the middle part of described worm screw 62, described worm gear 64 and described ball-screw 5 are for being connected with a joggle.Described servomotor 61 is fixed on driving mechanism casing 8.Therefore, described driving mechanism 6 can drive worm screw 62 to drive ball-screw 5 to move up and down by mechanical handwheel 63, or drives worm screw 62 to drive on ball-screw 5 or lower movement by servomotor 61.
The principle of work that a kind of portable force value of the present utility model loads pick-up unit is as follows:
First portable force value being loaded pick-up unit is positioned on universal testing machine 1, and set standard dynamometer or standard transducer 3, start servomotor 61 and drive worm screw 62 forward or reverse, by being fixed on the worm gear 64 on worm screw 62, drive on the ball-screw 5 that is meshed with it or lower movement, thus make the upper or lower movement also corresponding for the pedestal 4 rotating standard dynamometer or standard transducer 3 that be fixedly linked to ball-screw 5 top, standard dynamometer or standard transducer 3 is made to apply force value to the tested sensor 2 on moving beam, thus pass through the value of the acting force measured from standard dynamometer or standard transducer 3 and tested sensor 2, the degree of accuracy of tested sensor 2 just can be detected.
