The present invention adopts following technical scheme to realize: electric machine stand form and position tolerance pick-up unit comprises support section, test section and localization part; Described support section comprises base and symmetrical two supports that are installed on base upper surface; Each fixes two support bottoms with base upper surface, and two cantilever tip respectively are fixed with a reference block; Two reference block upper surfaces respectively have a V-shaped groove, and the center line of two V-shaped grooves is located along the same line; Described test section comprises rotating shaft; The symmetrical cover in rotating shaft two ends intrinsic two can be along the axially movable indicator bracket of rotating shaft; The rotating shaft two ends are supported in respectively in two V-shaped grooves; A dial gauge respectively is installed on two indicator brackets, respectively is equipped with one on two dial gauges and lengthens gauge outfit; Described localization part comprises that symmetry is installed on four groups of locating devices of base upper surface, and every group of locating device includes a coarse positioning seat, a bearing and an adjustable supports; Four coarse positioning seat bottom surfaces are all fixed with base upper surface, and four coarse positioning seat upper surfaces respectively are equipped with a locating piece, and wherein two coarse positioning seat sides respectively are equipped with a side locating piece; Four bottom surface of support saddles are all fixed with base upper surface, and on four bearings, an adjustment bolt are installed respectively; Four adjustable supports bottom surfaces are all fixed with base upper surface.The structure of described coarse positioning seat, bearing, adjustable supports, locating piece, side locating piece is the structure that those skilled in the art easily realize, it all designs according to the actual concrete structure of support.
During work, support bottom is installed on four coarse positioning seats, base inner is passed in rotating shaft, and with the rotating shaft two end supports in the V-shaped groove of two reference blocks, the axial location of mobile indicator bracket in rotating shaft makes the lengthening gauge outfit of dial gauge be pressed on the two ends seam disc of support.Regulate up and down, the position, left and right of supports by the adjustment bolt on four bearings and four adjustable supports, manual rotation rotating shaft simultaneously, according to the reading of dial gauge with seam center, support two ends centering.Regulate completely, then according to the axial location of position adjustments indicator bracket in rotating shaft of support, can the form and position tolerance of support be detected.Concrete testing process is as follows: one, support endoporus unshakable in one's determination is for the detection of the right alignment at support center: the axial location of mobile indicator bracket in rotating shaft, make the lengthening gauge outfit of dial gauge be pressed on the inner hole surface unshakable in one's determination of support, then with one week of rotating shaft manual rotation, the difference of the sizes values of dial gauge reading is this position endoporus unshakable in one's determination for the circular runout at support center at this moment.The difference that then detects endoporus unshakable in one's determination according to same method is cut the circular runout at circle place, COMPREHENSIVE CALCULATING can obtain endoporus unshakable in one's determination for the total run-out amount at support center, according to the total run-out amount of the endoporus unshakable in one's determination right alignment of intracardiac hole for the support center of can approximate treatment tapping a blast furnace.Two, the support end face is for the detection of the verticality at support center: the axial location of mobile indicator bracket in rotating shaft, make the lengthening gauge outfit of dial gauge be pressed on the support end face, in different radial location rotating shaft difference one weeks of manual rotation, the difference of the sizes values of dial gauge reading is the verticality of support end face.Three, the support seam is for the detection of the circular runout at support center: the axial location of mobile indicator bracket in rotating shaft, make the lengthening gauge outfit of dial gauge be pressed on the two ends seam disc of support, then with one week of rotating shaft manual rotation, the difference of the sizes values of dial gauge reading is the circular runout of support seam at this moment.Based on said process, electric machine stand form and position tolerance pick-up unit of the present invention realized every of support full inspection, namely realized support endoporus unshakable in one's determination for the right alignment at support center, end face for the disposable detection of craft for the form and position tolerances such as circular runout at support center of the verticality at support center, seam.Therefore, compare with existing electric machine stand form and position tolerance detection technique, not only detection efficiency is higher for electric machine stand form and position tolerance pick-up unit of the present invention, and testing cost is lower.
Further, described support section also comprises a baffle plate; The outer surface of baffle plate lower end and one of them support is fixed, baffle plate upper end and rotating shaft one end position over against.Baffle plate moves vertically or skids off in the time of can preventing the rotating shaft rotation.
The present invention is based on brand-new form and position tolerance detection architecture, efficiently solve the existing problem that electric machine stand form and position tolerance detection technique detection efficiency is low and testing cost is high, be applicable to the form and position tolerance of electric machine stand is detected.
