Drawings
FIG. 1 is a schematic structural diagram of the present invention;
fig. 2 is a schematic structural diagram of another embodiment of the present invention.
In the figure: 1. the device comprises a vertical rod, 2 micrometer, 3 crossbeam, 4 slideway, 5 end socket, 6 workbench, 7 electric control device, 8 base, 9 adjusting cushion block and 10 standard measuring plate.
Detailed Description
The following further describes particular embodiments of the present invention to facilitate further understanding of the present invention by those skilled in the art, and does not constitute a limitation to the right thereof.
Referring to fig. 1 and 2, the seal head flatness inspection tool comprises a base 8 and a rotatable workbench 6 mounted on the base, wherein an adjusting cushion block 9 capable of adjusting the height of the workbench is mounted at the bottom of the base; place head 5 that the opening faces upward on the workstation, the top of head is equipped with head flatness measuring device, one side of workstation is equipped with the crane that is used for hanging flatness measuring device, the crane is including setting up pole setting 1 in base one side, install crossbeam 3 in the pole setting of liftable, the crossbeam bottom is equipped with slide 4, gliding slider of installing on the slide, flatness detecting device hoists on the slider.
The flatness measuring device is a dial gauge and/or a standard measuring plate
The flatness measuring device also comprises a sheet-type feeler gauge matched with the standard measuring plate.
And an electric control device for driving the workbench to rotate is arranged on the base.
When the flatness detection device is a hundred (thousand) minutes meter, the specific operation steps of detecting the flatness by using the detection tool are as follows:
the first step is as follows: when the inspection is carried out, the workbench and the end socket are required to be kept free of impurities or dirt such as oil stain and water, and the surface of the workbench and the outer wall of the bottom of the end socket are required to be cleaned.
The second step is that: the method comprises the steps of measuring the background flatness of a position, to be contacted with an end enclosure, of a workbench, adsorbing a hundred (thousand) parts meter on a cross beam, moving the cross beam downwards to enable the hundred (thousand) parts meter to be contacted with the workbench, adjusting the contact depth of a dial indicator, starting the workbench to automatically rotate, measuring the background flatness condition of the workbench, and adjusting the flatness of the platform by using an adjusting sizing block. The surface flatness error of the conventional workbench can reach within +/-0.01 mm, the detection data of the seal head is not influenced, the deviation position of the bottom flatness of the workbench can be marked, and data correction is carried out after the seal head data are subsequently measured. And (5) taking down the dial indicator after the measurement is finished, and removing the cross beam.
The third step: the port of the seal head is upwards placed on the workbench, the seal head is freely placed without being interfered by other external force, the lowest point of the seal head is stably contacted with the plane of the workbench, and no sundries or dirt exists between the contact surfaces (points) of the seal head and the workbench. Dividing the plane of the end socket into four (0 degrees, 90 degrees, 180 degrees and 270 degrees) equal parts, marking by using a marker pen, measuring the heights of the four equal parts by using a height gauge, and adjusting to similar heights.
The fourth step: and adsorbing the dial indicator on a sliding rod below the cross beam, moving the cross beam downwards to enable the dial indicator to be in contact with the seal head plane, starting the workbench to rotate to a position of 0 degree after the contact depth of the dial indicator is adjusted, stopping rotating to record data, starting the workbench to automatically rotate for one circle by taking the position as a starting point, measuring the flatness condition of a seal head port, and recording the difference between the maximum value and the minimum value of one circle of data to be the actual flatness condition of the seal head. If the requirement is higher, the deviation of the flatness of the bottom of the worktable, which is measured before, can be used for correcting data. And (4) removing the cross beam, taking down the dial indicator and taking down the end socket.
When the flatness detection device is a standard measurement plate matched with the sheet-type feeler gauge for use, the specific operation steps of detecting the flatness by using the detection tool are as follows:
the first step is as follows: when the inspection is carried out, the workbench and the end socket are required to be kept free of impurities or dirt such as oil stain and water, and the surface of the workbench and the outer wall of the bottom of the end socket are required to be cleaned.
The second step is that: and placing the seal head on the workbench with the port upward. The standard platform is adjusted to be capable of completely covering the end face of the end socket relative to the end socket, so that the standard platform is attached to the end socket, and the circle center position of the standard platform coincides with the lowest point of the end socket due to the dead weight of the standard platform.
The third step: and (4) checking the gaps between the end sockets and the standard plane one by using a sheet type feeler gauge to obtain a flatness value. The fourth step: and after the inspection is finished, lifting the standard plane, removing the cross beam and taking down the seal head.
