DETAILED DESCRIPTION

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0014] An embodiment of the present utility model: A compressor vane verticality inspection tool, comprising a measuring tool base 1, a table frame support seat 2 is provided on the surface of the measuring tool base 1, a positioning contact 6 and a dial indicator 5 are horizontally mounted on the table frame support seat 2, wherein the positioning contact 6 is located directly below the measuring rod of the dial indicator 5, and a V-shaped positioning block 3 is further provided on the measuring tool base 1 on the side to which the positioning contact 6 and the measuring rod of the dial indicator 5 point. A V-shaped groove is provided on the surface of the V-shaped positioning block 3, and the V-shaped groove is parallel to the axis of the pointer of the dial indicator 5 and is in the same vertical section. An adjustment positioning support seat 8 is further provided on the measuring tool base 1 on the side of the V-shaped positioning block 3, and an adjustment screw 9 is provided on the adjustment positioning support seat 8 along the longitudinal direction.

[0015] The dial indicator 5 passes through the measuring rod of the meter stand support seat 2 and is sleeved with a bushing 10. The top of the meter stand support seat 2 is provided with a locking screw 7. After the dial indicator 5 is installed in the meter stand support seat 2, it can be locked and fixed by the locking screw 7.

[0016] The table frame support seat 2 and the adjustment and positioning support seat 8 are respectively fixed to the measuring tool base 1 via the locking bolts A11 and B12, so as to facilitate the installation, disassembly and replacement of parts.

[0017] A foot bolt 13 is provided at the bottom of the measuring tool base 1 to facilitate leveling of the measuring tool base 1 .

[0018] Use the device of the utility model to Figure 3 When checking the verticality of the compressor vanes shown in the figure, first follow the Figure 1 Assemble the inspection fixture of this utility model and ensure that the assembled inspection fixture meets the requirements Figure 2 assembly accuracy.

[0019] The detection method is as follows: first, a compressor vane standard part (qualified products are detected by other methods) is fixed on the V-groove of the V-shaped positioning block 3. During the fixing process, the spherical structure end of the compressor vane standard part is placed into the V-groove. By adjusting the position of the micrometer 5, the pointer of the micrometer 5 has an extension and contraction of 0.02mm-0.03mm. Then, the adjusting screw 9 is rotated so that the head end of the adjusting screw 9 is against the side of the compressor vane standard part, so that the needle detection point of the head end of the measuring rod of the micrometer 5 is located in the middle position of the B surface / C surface of the compressor vane standard part, and the dial of the micrometer 5 is adjusted so that the pointer points to 0. At this time, the compressor vane verticality inspection tool is adjusted. Remove the compressor vane standard part and place the compressor vane 4 to be tested. Then, the verticality of the B surface / C surface to the D surface of the compressor vane 4 can be measured. Place the compressor vane 4 into the V-shaped positioning block 3 so that its side is against the adjusting screw 9. The B surface / C surface of the compressor vane 4 contacts the positioning contact 6 and the needle at the end of the measuring rod of the micrometer 5. Read the value on the micrometer 5. The deviation between the read value and the 0 position of the standard part is the actual value of the verticality.
