On the point of clamp base circumferential plane trisection, there are two to coincide with the workpiece shape and can cooperate fixing gauge point with workpiece, be two anchor points of fixation workpiece, thirdly be unsteady point; Its position is on the perpendicular bisector of two point of fixity, measures on the measurement disk of mouthful configured in parallel with braking clamp body, directes reach the circumference measurement point by the center of circle, and a groove is arranged, upper and lower two bars of the smooth contact of configuration in the groove; The lower beam front end is the unsteady pressure head in location, and pressure head heads on the groove limit epitaxial planar of brake-caliper opening end embedding O-ring seal, and rod rear end connects the first powerful spring; Upper boom is a sounding rod, contacts with O-ring seal, and rod rear end connects second spring, and two springs all are fixed on the spring base that is stretched out by base; There are smooth 45 degree inclined-planes the sounding rod below, and 45 degree smooth bevels on the flat formula push rod of same level commentaries on classics vertical movement are meshed, and are in the push rod of rotation center, pass lower beam, are connected with displacement transducer, and displacement transducer output connects industrial control computer.
Good effect behind enforcement the utility model is:
1, can check out that part caliper sealing processes defective workpiece with groove, O-ring seal and also can support the assembly performance of holding two parts, can pick out underproof assembly parts, guaranteed assembly quality.
2, the bikini location, a point floating can be converted to dynamic benchmark with benchmark, eliminates the measuring error that fiducial error brings.Improve measuring reliability.Promote unsteady probe at the measuring process medi-spring, can adjust the center automatically.Unsteady measuring basis can reduce the positioning requirements of part on anchor clamps, before not using the location of floating, product design need be more accurate with the two pilot holes processing of braking clamp body, after adopting the location of floating, can loosen the requirement of alignment tolerance, reduce manufacturing cost.

Embodiment
Now the utility model is described in further detail in conjunction with the accompanying drawings
A kind of measurement mechanism that is used for braking clamp body with embedded sealing ring comprises the workpiece detent mechanism, clamp system, and measuring head rotating mechanism and measurement data derivation mechanism, and have the driven wheel of driven by motor and follower gear to mesh; Its structure is:
On the point of clamp base circumferential plane trisection, there are two to coincide with the workpiece shape and can cooperate fixing gauge point 25,26 with workpiece, be two anchor points of fixation workpiece, thirdly be unsteady point; Its position is on the perpendicular bisector of two point of fixity, measures on the measurement disk of mouthful configured in parallel with braking clamp body 1, directes reach the circumference measurement point by the center of circle, and a groove 27 is arranged, upper and lower two bars of the smooth contact of configuration in the groove; Lower beam 22 front ends are the unsteady pressure head in location, and pressure head heads on the groove limit epitaxial planar 28 of caliper 1 openend embedding O-ring seal 2, and rod rear end connects the first powerful spring 18; Upper boom is a sounding rod 23, contacts with O-ring seal 2, and rod rear end connects second spring, 20, two springs and all is fixed on the spring base 19 that is stretched out by base; There are smooth 45 degree inclined-planes 29 sounding rod 23 belows, 45 degree smooth bevels on the flat formula push rod 24 of same level commentaries on classics vertical movement are meshed, and are in the push rod 24 of rotation center, pass lower beam 22, be connected with displacement transducer 11, displacement transducer output connects industrial control computer.
Specific operation process is:
This device is a kind of measurement mechanism that is applied to braking clamp body with embedded sealing ring, is used to check braking clamp body and O-ring seal crudy and both fit qualities.
The braking clamp body inner chamber is cylindrical, is used to hold brake oil, and piston provides brake power in the brake oil promotion inner chamber.Seal groove is an irregular ring groove, and processing is difficult, and is not easy to check.O-ring seal is that the material that a cross section is a rectangle is the annulus of rubber.
So the structure that adopts is a bikini endoporus clamp system, the workpiece detent mechanism that the upper clamping mechanism of workpiece is formed: vertical direction disposes two cylindrical backstays 3, with the left and right sides earhole cooperation of braking clamp body, determines the horizontal level of workpiece.Cylindrical backstay can slide in cylindrical backstay guide pillar 5.Spring 4 promotes cylindrical backstay and abuts against on the backstay base.The backstay base has two positions up and down, the upper-lower position of corresponding cylinder 8.Workpiece clamps under the effect of last anchor clamps 6, guarantees the displacement under supreme.
The workpiece horizontal location is determined that by the three-point fix clamp system 2: 25,26 is fixing, and another point constitutes unsteady point by pressure head 22 and spring 18, and under the effect of spring force, the assurance anchor clamps are fitted all the time with workpiece.
Braking clamp body 1 installs to clamp base 7 by the mounting hole on both sides, by 3 fixed of backstays, pushes down with a spring chuck above.The centralized positioning of workpiece on anchor clamps is made of point of fixity on the workpiece endoporus positioning seat 21 on the clamp base 25,26 and location floating probe 22.Promote rotation measurer base 17 by turning axle 16, the workpiece calibration probe 23 on it keeps with O-ring seal 2 contacts under the promotion of spring 20.The amount of movement of workpiece calibration probe 23 is O-ring seal variable quantities with respect to the center, hole.Moving of workpiece calibration probe 23 is by the inclined-plane promotion push rod 24 of 45 degree; Moving of push rod 24 promotes to be contained in the displacement transducer 11 on the base 9, and displacement transducer is converted into electric weight with displacement movement; Displacement transducer is connected with industrial control computer, and industrial control computer is reduced to displacement and record and processing by special software processes electric weight with electric weight.
