Embodiment
1 is main structure body among the figure, and 2 for promoting cone, and 3 is the detecting head body, and 4 is screw rod, 5 is steel ball, and 6 is handle, and 7 is the handle terminal, and 8 is spring capping, 9 is spring, and 10 is axle bed, and 11 are the rotation arm axle, and 12 is copper sheathing, 13 is pivot arm, and 14 is adjusting pad, and 15 is plain cushion, and 16 is nut, 17 is split collar, and 18 is gib screw, and 19,20,21,22 is float, 23 is gib screw, and 24 is dial gauge, and 25 is the tested part gear wheel.
Principle of work: generally with the steel ball locking, the axial location of the runway R groove of steel ball has determined whether thrust surface can be adjacent to the axial location of the gear wheel of oil cone bit and bit leg axle, and the bearing pin that meets performance requirement is arranged to collecting together momentum.The gear wheel hole R-groove axial position measuring instrument can accurately be measured the axial location of gear wheel hole R groove.This measuring instrument promotes the cone inclined-plane by the screw thread rotation in the mechanical hook-up and produces displacement, carry detecting head and outwards protrude, the gear wheel hole R groove of locking tooth-wheel bit is measured the gear wheel end face with dial gauge, compare with reference field, calculate the axial location exact value of gear wheel R groove.Dial gauge is fixed on the armshaft that can rotate arbitrarily, it is axially collected together momentum be adjusted into 0, arbitrarily the optional position of measuring basis face and tested part end face.The float that is provided with in the measuring instrument can be used to measure the axial dimension of each end face in the gear wheel hole, realizes the disposable multi-section position physical dimension that measures, and has simplified the check program to part.
Execute example: as shown in Figure 1, oil cone bit gear wheel hole R-groove axial position measuring instrument of the present invention, comprise main structure body (1) and promote cone (2), main body (1) is provided with screw rod (4), and screw rod (4) promotes cone (2) by handle (6,7) rotation and drive and moves down.
As Fig. 1, shown in Figure 3, three inclined-planes (201) that promote cone (2) cooperate with the inclined-plane (301) of three detecting head bodies (3), make three detecting heads (302) outwards protrude from main body (1), screw screw rod (4), three detecting heads (302) are locked in the R groove of tested gear wheel (25).Three detecting head bodies (3) and three detecting heads (302) must remain on the same sagittal plane, otherwise measurement result is incorrect.Dial gauge (24) is clamped on the pivot arm (13) by split collar (17) and gib screw (18), and the other end of pivot arm (13) cooperates with rotation arm axle (11) by copper sheathing (12), and pivot arm (13) can be rotated arbitrarily around rotation arm axle (11).The last plane (101) of main body (1) is a reference field, with the measured size reading of dial gauge (24) and the read-around ratio that reference field is measured, calculates the axial location size exact value of R groove.Pivot arm (13) can not have on rotation arm axle (11) axially collects together momentum, otherwise survey measurements is inaccurate.Adjust the thickness of adjusting pad (14), after nut (16) locking, making the momentum of axially collecting together of pivot arm is 0, but can not be locked, and pivot arm (13) can be free to rotate to any part that needs measurement.
The length size of pivot arm (13) will be according in its rotary course, and can reach all should sites measured, can increase other mechanism like this, as long as reach the purpose of measurement by the length of adjustment pivot arm (13).
Steel ball (5) cooperates with screw rod (4) and promotion cone (2), forms bearing, and this bearing has the effect of thrust bearing concurrently.When screw rod (4) rotation moves down, promote cone (2) and only make shifting movement down.Spring (9) is fixing by spring capping (8), and when moving on promoting cone (2), detecting head body (3) can automatically restore to the original position.
As Fig. 1, shown in Figure 2, the float (19) that this instrument is provided with, (20), (21), (22) be used for subsidiary thrust surface (2501) and closed chamber end face axial position, its setting principle of position in instrument is to make arriving of dial gauge (24) measurement, can touch tested end face again. float (19), (20) be used for measuring thrust surface (2501), float (21), (22) be used for measuring the closed chamber end face. when the length adjustment of float should be with the measurement standard end face, its tested end face with reference field (101) if measured value consistent. also need to measure little axis hole end face, as long as set up one pair of float, using can be convenient.
