Embodiment
Below in conjunction with accompanying drawing, describe the enforcement and the use of preferred implementation in detail.Yet, should be appreciated that the specific embodiment discussed only exemplarily explanation implement and use ad hoc fashion of the present invention, and unrestricted scope of the present 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; Said assisted calibration device comprises L type web joint 1, and its long limit has formed the installation portion 1a that is used for detachably installing pull and push dynamometer 9, and 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 through jointing 2 is connected to a force application apparatus (figure does not show), and at this, this force application apparatus is preferably force standard machines.Calibrate than lifting as the pull and push dynamometer in power source of present use by manual work; The present invention is through 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, can precision brought up to 0.01% basically from existing below 0.1%.
Further combine Fig. 3 visible, the installation portion 1a of web joint 1 is provided with for example three groups of mounting holes 4, and it is all different respectively to organize the position distribution of mounting hole 4.It is understandable that the pull and push dynamometer that such design can be adapted to various different models are installed is 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, repeats no more at this.
When pulling to the power value calibration, as shown in Figure 1, because being placed to inverted L shape, web joint 1 uses, 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 said connecting portion 1b along the bearing of trend of said connecting portion 1b.The mounting hole 6 that is used to connect dynamic balance adjusting gear 3 has been shown among Fig. 3.According to a kind of embodiment; Said dynamic balance regulating device 3 comprises weight linear meter 3a and is socketed in the balancing weight 3b on the said weight linear meter 3a; Said weight linear meter 3a and said balancing weight 3b be through being threaded, and makes that said balancing weight 3b can be along the moving axially of said weight linear meter 3a, thereby can change the center of gravity of whole assisted calibration device; Make its power value direction coaxial, and then realize accurate and reliable calibration pull and push dynamometer 9 with force standard machines.
When needs were pressed to the power value calibration to pull and push dynamometer 9, web joint 1 is placed with positive L type and uses, and was as shown in Figure 2.At this moment; Jointing 2 can be used as a connection platform, is used for the web joint 1 that pull and push dynamometer 9 has been installed is fixedly attached to a base (figure does not show), and; No longer need dynamic balance regulating device 3, calibrate but act 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 pull and push dynamometer 9 be adjusted to the coaxial position of power value direction with force standard machines in when calibration.Equally, the installation portion 1a of web joint 1 goes up the mounting hole 4 that is provided with and also can only be provided with 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.
Through 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) scalable 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 above-mentioned disclosed design of the present invention and embodiment, as the basis of revising and design other structures or process, so that 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 purport of the present invention and the scope of putting down in writing in the appended claims.
