A support and positioning device for outer diameter micrometer measurement

Abstract

The invention relates to the technical field of supporting and positioning for outside micrometer measurement, in particular to a support positioning device for outside micrometer measurement. A method of outside measurement in traditional vertical lathing and vertical grinding includes: horizontally placing an outside micrometer rest on left and right arms; holding the outside micrometer with both hands and holding sheaths on a measuring anvil and a micrometer bolt; turning a ratchet knob with the thumb and index finger of the right hand. According to the method, measurement is time consuming and labor consuming, and measurement errors occur easily. The support positioning device comprises a V-shaped support plate, a countersunk screw, a connecting disc, a lifting sleeve, a long bolt, a locknut, and a bracket base. The lifting sleeve and the bracket base can move up and down and position along the long bolt independently. The lifting sleeve drives the V-shaped support plate to move up and down; meanwhile, the V-shaped support plate can also rotate by 360 degrees independently. The support positioning device is reasonable in structure and simple to operate; the influence of micrometer weight upon measurement results during measuring the machined outside surface in vertical lathing and vertical grinding measurement can be eliminated; measurement accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of support and positioning for outer diameter micrometer measurement, in particular to a support and positioning device for outer diameter micrometer measurement, which is used for measuring the processed outer circular surface by vertical lathes and vertical mills. The support and positioning device used for the measurement of the diameter micrometer completely solves the influence of the weight of the micrometer on the measurement results and effectively improves the accuracy of the measurement. Background technique [0002] When measuring the processed outer surface of the vertical lathe or vertical mill, the traditional outer micrometer measurement method one is: first place the outer micrometer frame flat on the left and right arms, hold the outer micrometer firmly with the left and right hands, measure the anvil and At the sheath of the micrometer screw, use the thumb and index finger of the right hand...

AI Technical Summary

Problems solved by technology

The above three methods all transfer the entire weight of the outer micrometer to the wrist and arms of the measurer, and at the same time find the measurement position, and then use the right thumb and index finger to twist the ratchet handle, which is time-consuming and laborious. big error

Grasping the frame of the outer micrometer for a long time will easily cause fatigue in the arms and wrists, and the measurement accuracy will be greatly reduced
