市场经济环境提高了对机床质量的要求,因此,对于与操纵灵活、轻便、减轻劳动强度等相关的,甚至最细小的同题都应予以重视。测量机床手柄的作用力是这些课题之一,因为尚无国产的相应的测量仪器。亚美尼亚科研设计院在2K522型钻床上试验,研制出了可以用于完成这些目的的测量装置(见插图)。该装置是在换档(速) 手柄顺时针或逆时针转动过程中测量的。这种测量装置的结构包括有外圈6、轮轱3、手柄5、承载辊子12、弹性电桥8和显示器10。轮轱由螺钉2紧固在装有换档的手柄11的轴头1上,此时下面的换档手柄进入到轮轱的凹口内。在轮轱
The market economy has raised the demand for the quality of machine tools. Therefore, attention should be paid to the same topics as the smallest ones that are relevant to the manipulation of flexibility, lightness and labor intensity reduction. Measuring the force of the machine handle is one of these topics, because there is no corresponding domestic measuring instruments. Armenia Research and Design Institute in the Model 2K522 drill on the test, developed a measurement device can be used to accomplish these purposes (see inset). The device is measured during the clockwise or counterclockwise rotation of the shift handle. The structure of this measuring device comprises an outer ring 6, a wheel rim 3, a handle 5, a carrying roller 12, a flex bridge 8 and a display 10. The wheel rim is fastened by a screw 2 to the shaft head 1 of the gear-equipped handle 11, with the lower shift handle entering the notch of the wheel rim. In the wheel
