Embodiment
Below in conjunction with accompanying drawing, describe enforcement and the use of preferred implementation in detail.Yet, should be appreciated that the specific embodiment of discussing only exemplarily illustrates enforcement and uses ad hoc fashion of the present invention, but not limit the scope of the invention.
Fig. 1 and Fig. 2 show two kinds of calibration modes according to the assisted calibration device of pull and push dynamometer of the present invention respectively.At first referring to Fig. 1, described assisted calibration device comprises L type web joint 1, its long limit has formed and has been used for the detachable installation portion 1a that pull and push dynamometer 9 is installed, its minor face has then formed connecting portion 1b, be used for removably installing jointing 2, thereby the web joint 1 that will be mounted with pull and push dynamometer 9 by jointing 2 is connected to a force application apparatus (not shown), and at this, this force application apparatus is preferably force standard machines.The pull and push dynamometer by manually lifting as the power source than present use is calibrated, the present invention is by being derived from the moving proof force value that applies with force standard machines as proof force, safe and reliable, and the scope of application is big, precision can brought up to 0.01% substantially from existing below 0.1%.
Further combined with Fig. 3 as seen, the installation portion 1a of web joint 1 is provided with for example three groups of mounting holes 4, and the position distribution of respectively organizing mounting hole 4 is all different.Be understandable that such design can be adapted to install the pull and push dynamometer of various different models to enlarge the usable range of this assisted calibration device.Referring to Fig. 4, on connecting portion 1b, be provided with mounting hole 5 equally, but this mounting hole 5 is set to Long Circle simultaneously, makes the fixed position of jointing 2 on this connecting portion 1b correspondingly to adjust.Like this, for example utilizing, web member 7,8 such as bolt can be separately fixed at jointing 2 and pull and push dynamometer 9 on the L type web joint 1.Certainly, other connected mode also is possible, does not repeat them here.
When pulling to the power value calibration, as shown in Figure 1, because being placed to inverted L shape, web joint 1 uses, and the side force of introducing because of the center of gravity factor can balance the pulling force of part, and because the varying in weight of tested pull and push dynamometer 9, the side force of generation is also different.Therefore, assisted calibration device of the present invention also can comprise a dynamic balance regulating device 3, and this dynamic balance regulating device 3 can be removably mounted on the end of described connecting portion 1b along the bearing of trend of described connecting portion 1b.The mounting hole 6 that is used for connecting dynamic balance adjusting gear 3 has been shown among Fig. 3.According to a kind of embodiment, described dynamic balance regulating device 3 comprises weight linear meter 3a and the balancing weight 3b that is socketed on the described weight linear meter 3a, described weight linear meter 3a and described balancing weight 3b are by being threaded, make that described balancing weight 3b can moving axially along described weight linear meter 3a, thereby can change the center of gravity of whole assisted calibration device, make its power value direction with force standard machines coaxial, and then realize the accurate and reliable calibration to pull and push dynamometer 9.
When needs were pressed to the power value calibration to pull and push dynamometer 9, web joint 1 was placed with positive L type and uses, as shown in Figure 2.At this moment, jointing 2 can be used as a connection platform, is fixedly attached to a base (not shown) for the web joint 1 that pull and push dynamometer 9 will be installed, and, no longer need dynamic balance regulating device 3, calibrate but acted on the pull and push dynamometer 9 by the direct application of force of force standard machines.
In other embodiments, dynamic balance regulating device 3 also can be arranged to other structures, as long as can when calibration pull and push dynamometer 9 be adjusted to the position coaxial with the power value direction of force standard machines.Equally, the installation portion 1a of web joint 1 goes up the mounting hole 4 that arranges and also can only arrange one group to be exclusively used in the pull and push dynamometer of a certain model.If run into the pull and push dynamometer of special type, but field fabrication mounting hole 4 also.
By the description to above-mentioned preferred implementation, the assisted calibration device of being not difficult to draw pull and push dynamometer of the present invention has the following advantages:
(1) the proof force value that applies accurately and reliably;
What (2) be applicable to the polytypic pull and push dynamometer draws, presses the bidirectional force value calibration;
(3) can regulate center of gravity;
(4) be applicable to the calibration of wide range pull and push dynamometer.
It will be appreciated by those skilled in the art that and easily to use the above-mentioned disclosed design of the present invention and embodiment, as the basis of revising and design other structures or process, in order to carry out the purpose identical with the present invention.Those skilled in the art it is also understood that these equivalent structures do not break away from the spirit and scope of the invention of putting down in writing in the appended claims.
