Embodiment Construction
[0011] As shown in the figure, the specific implementation method is as follows:
[0012] A mechanical tappet air flotation centering measuring device, comprising a measuring base 4 with a groove and a sensor detection device, the sensor 3 of the sensor detection device cooperates with the measuring base 4 to realize data measurement, and the workpiece to be measured is placed on the In the groove, the balance of the workpiece is adjusted by introducing high-pressure airflow, and then the sensor extends into the workpiece and can be measured by cooperating with the measuring seat. The measuring seat 4 is provided with at least one row of evenly distributed Nozzle hole 2, an air flotation nozzle is installed in the nozzle hole 2, and the air flotation nozzle is connected to a high-pressure gas source 5 through an air pipeline.
[0013] The nozzle holes 2 are provided in two rows and each row is provided with three, so that the tool to be measured can be balanced under force and...

The invention discloses an air floating centring measurement device for a mechanical tappet. The air floating centring measurement device for the mechanical tappet comprises a measuring seat with a groove, and a sensor detecting device, wherein a sensor of the sensor detecting device and the measuring seat cooperate to realize the data measurement; at least one row of uniformly-distributed nozzle holes are formed in the side walls of the periphery of the groove in the measuring seat; an air floating nozzle is mounted in each nozzle hole and is connected with a high pressure gas source through a gas transporting pipeline. Because high pressure gas is fed through the nozzle holes formed in the measuring seat and the nozzle holes are uniformly arranged, the parts can keep balance when being placed on the measuring seat, and the parts can be placed in the measuring seat in a balance manner under the effect of high pressure gas flow and are prevented from being inclined, so that the accuracy of the measuring result can be guaranteed.
Description
technical field [0001] The invention relates to a measuring device for a mechanical tappet, in particular to an air-floating centering measuring device for a mechanical tappet. Background technique [0002] For mechanical tappet air floatation centering measurement, since the two surfaces to be measured are spherical, problems are likely to occur during measurement, and the upper and lower spherical surfaces are not on the center of the workpiece, which may easily cause the workpiece to tilt during measurement, resulting in large measurement errors. Contents of the invention [0003] The purpose of the present invention is to provide a mechanical lifter air-flotation centering measuring device to solve the problem of large measurement errors in the prior art. [0004] The present invention is for solving the deficiencies of the above-mentioned technical problems, and the technical scheme adopted is: [0005] A mechanical tappet air flotation centering measuring device, in...
