The valve diameter measurement mechanism
Technical field
The utility model relates to diameter measurement, relates in particular to a kind of valve diameter measurement mechanism.
Background technology
Utilize the method for displacement sensor article diameters in commercial measurement, to be widely used.In valve diameter is measured, standard valve body of machine work at first, physical dimension is identical with workpiece for measurement, and hardness, surfaceness and circularity precision all reach high-precision requirement.Then measure the diameter of this standard valve body with three-coordinates measuring machine.Then calibrate with this standard valve body contraposition displacement sensor, the diameter of namely setting this valve in the PLC program is consistent with the output of displacement transducer.When measuring common valve body, the diameter that contrast is measured and the difference value of standard valve diameter can obtain the diameter of valve body to be measured.The measurement of valve diameter is to the measuring accuracy requirement, and the requirement of repeatable accuracy is all very high, thereby to the very high requirement that is designed with of measurement mechanism.In the existing valve diameter measurement mechanism, measure the displacement transducer of diameter and drive cylinder not on same vertical line, in a distance.When hydraulic cylinder presses down when testing, because mismachining tolerance and rigging error can make the contact of displacement transducer and valve body unstable, so the numerical value that displacement transducer is measured also can out of true.Drive simultaneously the centre distance valve body to be measured of cylinder also in a distance, the mount pad that presses down displacement transducer in the process can bear certain moment, thereby causes the unstable and distortion of displacement sensor data.
Chinese utility model patent 200810200656.2 discloses a kind of coiled material alignment diameter-measuring device and method, comprise dolly, hydraulic cylinder, push rod, carriage, but be fixed with hydraulic cylinder on the dolly of move left and right, be fixed with push rod on the piston of hydraulic cylinder, the top of push rod is fixed with carriage, also comprise a plurality of displacement transducers, photoelectric sensor, A/D converter and PLC, realized calibrating and the centering control system coil of strip, but it still exists and may cause the unsettled problem of contact because of the load of hydraulic cylinder because of displacement transducer, measurement data distortion, and apparatus structure more complicated.
The utility model content
The shortcoming of prior art in view of the above, the purpose of this utility model is to provide a kind of valve diameter measurement mechanism, is used for solving the problems of the prior art.
Reach for achieving the above object other relevant purposes, the utility model provides a kind of valve diameter measurement mechanism, the straight line driving mechanism that comprises bearing support, slides up and down along bearing support, also comprise the upper anchor clamps that are located at described straight line driving mechanism bottom, be located at lower clamp corresponding with upper anchor clamps on the bearing support, form grasping part between the described upper and lower anchor clamps, described upper anchor clamps clamping is established a tangent displacement sensor in the chamber, and described tangent displacement sensor is positioned on the vertical center line in lower clamp clamping chamber.
Further, vertically be provided with line slideway on the described bearing support, described straight line driving mechanism is provided with the slide block that is complementary with described line slideway.
Further, described lower clamp clamping chamber is the V-type groove.
Further, described upper anchor clamps clamping chamber is half slot.
Further, described straight line driving mechanism is hydraulic cylinder.
Further, described tangent displacement sensor is connected with the digital display meter that is arranged on the external world by wire.
By above technical scheme, the utility model has improved the installation site of displacement transducer on hydraulic cylinder, itself and valve body to be measured are on the same vertical line, avoid displacement transducer to be subject to the load that except valve body to be measured itself, causes, greatly improved the accuracy of measuring diameter data.

Embodiment
Below by particular specific embodiment embodiment of the present utility model is described, person skilled in the art scholar can understand other advantages of the present utility model and effect easily by the disclosed content of this instructions.
See also Fig. 1 to Fig. 2.Notice, the appended graphic structure that illustrates of this instructions, ratio, size etc., equal contents in order to cooperate instructions to disclose only, understand and reading for person skilled in the art scholar, be not to limit the enforceable qualifications of the utility model, therefore the technical essential meaning of tool not, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under the effect that the utility model can produce and the purpose that can reach, all should still drop on the technology contents that the utility model discloses and get in the scope that can contain.Simultaneously, quote in this instructions as " on ", D score, " left side ", " right side ", " centre " reach the term of " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under without essence change technology contents, when also being considered as the enforceable category of the utility model.
As shown in Figure 1, the utility model provides a kind of valve diameter measurement mechanism, the straight line driving mechanism 2 that comprises bearing support 1, slides up and down along bearing support, it is hydraulic cylinder, also comprise the upper anchor clamps 3 that are located at straight line driving mechanism 2 bottoms, be located on the bearing support lower clamp 4 corresponding with upper anchor clamps 3, form the grasping part for the treatment of side valve body 5 between the upper and lower anchor clamps, upper anchor clamps clamping is established a tangent displacement sensor 6 in the chamber, and tangent displacement sensor 6 is positioned on the vertical center line in lower clamp clamping chamber.Valve body 5 to be measured is placed on the lower clamp 4, the mid point of valve body 5 to be measured be positioned at tangent displacement sensor 6 under.Starter gear, straight line driving mechanism 2 presses down tangent displacement sensor 6 is contacted with valve body 5 to be measured, tangent displacement sensor during with the contact measured valve body suffered pressure change into voltage or electric current, voltage by with default measurement standard valve body time the or current ratio are, convert the difference of curtage on the diameter the change of divergence, can finish diameter measurement.
