The first: use three-coordinates measuring machine to measure.Three-coordinates measuring machine belongs to a kind of surveying instrument of high, precision and frontier, very accurately can measure the actual value of inner race centre distance and circular arc, generally be applicable to the measurement of standard component.But its fund input is large, generally all wants hundreds of thousands; And its service condition is also quite harsh, needs the environment of constant temperature and humidity, needs away from vibration source, therefore production scene use cannot be positioned over, cannot Instructing manufacture activity fast.
The second: use center distance measurement instrument to measure.Movable block is connected with dial gauge with workpiece, can only move up and down, and two spheric probes are inlayed in movable block front end, with absorption surface.Workpiece is placed on after on platform close toward movable block, and can successively contact with two spheric probes, dial gauge reading will change, and after contacting completely with two gauge heads, dial gauge reading is just fixing, and this reading, compared with the reading of standard component, just can draw the situation of centre distance.This kind of method is suitable for using in production scene, but only can detect the centre distance situation of two contact positions, and can not represent the actual conditions of whole circular arc.
Utility model content
The purpose of this utility model is to provide a kind of cubing can measuring ball cage inner race spherical outside surface and interior alley centre distance fast, easily.
The technical scheme realizing the utility model object is: a kind of cubing for measuring ball cage inner race spherical outside surface and interior alley centre distance, comprises support, tackling, dial gauge and lock-screw; Described support is shaped as frame, and its side is provided with breach; The two ends up and down of described tackling are rotationally connected with the two ends up and down of the breach of support respectively; The front side of described tackling uncovered and axis and plane-parallel, its inner chamber is cylindrical, and the diameter of inner chamber and the maximum outside diameter of ball cage inner race match; The two ends, left and right of the periphery of described tackling are equipped with measurement breach, measure the two sides, front and back that breach extends to tackling; Described dial gauge horizontally slips with another side of support and is connected, and is locked on support by lock-screw; The gauge head of described dial gauge passes the measurement breach of tackling, and stretches in the inner chamber of tackling.
The two ends up and down of the breach of described support are equipped with thimble; The two ends up and down of described tackling are equipped with pilot hole; Two thimbles on the breach of described support are rotationally connected with the pilot hole at the two ends up and down of tackling respectively.
The measurement breach at the two ends, left and right of described tackling is all V-shaped, and its big uncork end is arranged outwardly.
Have employed technique scheme, the utility model has following beneficial effect: (1) the utility model only needs to be positioned in tackling by workpiece for measurement when measuring, the spherical outside surface of inner race or interior alley are placed in " V " type groove location, the gauge head of dial gauge can be touched on spherical outside surface, then rotate tackling and can complete measurement, very simply, quick, convenient; Rotate measured workpiece in addition and reach 180 °, just can one-time detection symmetry two spherical outside surfaces or the centre distance situation of interior alley, improve detection efficiency.
(2) the utility model not only fast and effeciently can measure inner race spherical outside surface and the difference between interior alley centre distance and standard component centre distance, and while wheel measuring, the circular arc degree of spherical outside surface circular arc and interior alley circular arc can be shown very intuitively, practicality very, cost is very low simultaneously.
(3) two thimbles on the breach of support of the present utility model are rotationally connected with the pilot hole at the two ends up and down of tackling respectively, and this structure can ensure tackling when rotated, and rotation does not offset, thus improve measuring accuracy.
(4) the measurement breach at the two ends, left and right of tackling of the present utility model is all V-shaped, and its big uncork end is arranged outwardly, this structure, is convenient to install dial gauge, thus is convenient for measuring.
Accompanying drawing explanation
In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the axial cut-open view of tackling of the present utility model.
Label in accompanying drawing is:
Support 1, thimble 11, tackling 2, pilot hole 21, measurement breach 22, dial gauge 3, lock-screw 4.
Embodiment
(embodiment 1)
See Fig. 1 and Fig. 2, the cubing for measuring ball cage inner race spherical outside surface and interior alley centre distance of the present embodiment, comprises support 1, tackling 2, dial gauge 3 and lock-screw 4.
Support 1 is in shaped as frame, and its side is provided with breach.The two ends up and down of the breach of support 1 are equipped with thimble 11.The front side of tackling 2 uncovered and axis and plane-parallel, its inner chamber is cylindrical, and the diameter of inner chamber and the maximum outside diameter of ball cage inner race match.The two ends up and down of tackling 2 are equipped with pilot hole 21.Two thimbles on the breach of support 1 are rotationally connected with the pilot hole 21 at the two ends up and down of tackling 2 respectively.The two ends, left and right of the periphery of tackling 2 are equipped with measures breach 22, measures the two sides, front and back that breach 22 extends to tackling 2.The measurement breach 22 at the two ends, left and right of tackling 2 is all V-shaped, and its big uncork end is arranged outwardly.Dial gauge 3 horizontally slips with another side of support 1 and is connected, and is locked on support 1 by lock-screw 4.The gauge head of dial gauge 3 passes the measurement breach 22 of tackling 2, and stretches in the inner chamber of tackling 2.
When measuring inner race spherical outside surface centre distance, first use standard component school zero, the position of adjustment dial gauge 3 and meter-pressing amount; Again workpiece for measurement is positioned in tackling 2, any one of inner race spherical outside surface part is placed in " V " type groove location, the gauge head of dial gauge 3 can be touched on spherical outside surface, then tackling 2 is rotated, observe the hunting range of the pointer of dial gauge 3, as also swung in zero-bit, illustrate that measured workpiece is consistent with the spherical outside surface centre distance of standard component, product is qualified; Otherwise, as pointer differs comparatively large with zero reading, illustrate that the spherical outside surface centre distance of measured workpiece and standard component is inconsistent, need to adjust processing tool.In addition, once rotate measured workpiece reach 180 °, just can one-time detection symmetry two spherical outside surfaces centre distance situation, improve detection efficiency.
When measuring alley centre distance in inner race, method is similar to measurement spherical outside surface centre distance, and when difference is that inner race is positioned in tackling 2, the notch position of alley contacts with the gauge head of dial gauge 3.
