Bakelite handle machine manipulation force measuring device

Market economic environment improves the quality requirements of the machine , therefore, relevant , and even the smallest problem with manipulating a flexible , lightweight, reduce labor intensity should be valued. Bakelite handle the force measuring machine is one of these issues , because there is no domestic production of the corresponding measurement instruments. Armenian Academy of research based sauce on 2 K 5 can type drilling test , developed can be used to accomplish these purposes , such as measuring devices.
    The measuring means is a shift ( speed ) in a clockwise or counterclockwise rotation of the handle bakelite process . This structure includes a measuring device 6 has an outer ring , dry three rounds , bakelite handle 5 , the roller bearing 12 , an elastic bridge 8 and a display 10 . Fastened by screws 2 rotate with the shift lever to the shaft of bakelite head 1 1 , then the following shift lever bakelite drilled into a recess of the inner ring . Dead ends at the wheel used to have a concave profile bridge bearing seat 8 , dowel pin at the top of the display at the bridge , fastened by screws 9 .
    The outer ring is fastened by screws 4 wheel on dry ( dry screw into the annular groove in the wheel ) , it has some special groove for mounting the roller assembly and tighten the screws on the wheel 7 withered bridge . For ease of measurement, clock-type display with 0.001 mm indexing values. For the measurement more convenient, but also used the small size of the 223 converter 14 alternative displays, the converter access to electronic measurement system 15 .
    Electronic measuring system able to measure from 0.1 to 120 microns to five scale deflection of the bridge. The device according to the method described Bian work : When Bakelite handle 5 is rotated to drive the outer ring 6 , the force applied at this time spread by a roller bridge, the monitor will record the deformation of the bridge.
    Bakelite handle an instantaneous movement of the force should not exceed 40 cows. Hanging load of the prior machining a hole in the handle 5 bakelite , and some processing on the outer threaded holes for loading the calibration weight after tightening handle bakelite 5 of the apparatus according to the following measuring methods to achieve : the wheel is mounted to the dry state in the extrusion mandrel so that the mandrel pin napkin 13 mm into the groove of the wheel dry .
    Then, the handle 5 is screwed into bakelite a threaded hole 13 of a horizontal configuration , and the two rotary screw tight on the mandrel . Cured code as bakelite handle with a load ( from 0.5kg to 4.5kg, a time increasing load 0.5kg ) , which was hanging on bakelite handle. when the load hanging on the bakelite handle can move along a minor . with each reading corresponding to the load on the converter 's display or to record statistics table .
    Test was repeated three times and the average value is determined . Relations by force to make graphs . Finally, a reading error when bakelite handle clockwise or counterclockwise , may exist between each other . The device reading error (B%) 6 two 10 0 (. MZ an M) / MZ ( here , MZ force calibration curve represents the relationship ;. M represents the actual force relationship ) , 6 should not exceed ± 10% . The device can be used to measure the force and extent of any form of manipulation of the handle bakelite . This should be a set of replaceable rotation.
