DETAILED DESCRIPTION

[0021] In order to make the purpose, content and advantages of the present invention more clear, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples.

[0022] See also Figures 1 to 3The O-to-T combined test fixture for testing the turntable in this embodiment includes an O-to-T test frame 100, an optical platform 200 and a screw 300. The O-to-T test frame 100 is positioned with the O-type turntable through a pin, the O-to-T test frame 100 and the O-type turntable are fastened by a fastening screw, the optical platform 200 is fixed on the O-to-T test frame 100 by the screw 300, and the product to be tested is placed on the optical platform 200 for adjustment and testing.

[0023] The O-to-T test frame 100 is made of cast aluminum alloy, the optical platform 200 is a common optical platform sold in the market, and the screw 300 is preferably a hexagon socket head screw.

[0024] The O-to-T test stand 100 includes a circular flange surface and a flange ring 130 located inside the flange surface. The flange surface is installed in contact with the end surface of the O-type turntable, and the flange ring 130 matches the inner wall of the O-type turntable.

[0025] The flange surface is provided with 8 evenly distributed threaded through holes 120 and 2 symmetrically distributed pin holes 110. The pin holes 110 are aligned with the positioning holes on the O-type turntable to ensure that the O-to-T test frame 100 and the O-type turntable are aligned with concentric circles. The threaded through holes 120 are used to pass screws to fasten the O-to-T test frame 100 and the O-type turntable together.

[0026] The flange ring is used to conform to the inner circle of the O-type turntable and play a guiding and auxiliary installation role.

[0027] The O-to-T test stand 100 further includes a horizontal plane located in the circular inner cavity of the flange surface and perpendicular to the flange surface, and the optical platform 200 is mounted on the horizontal plane.

[0028] A plurality of small circular bosses 140 are designed on the horizontal plane, and the small circular bosses 140 maintain a consistent horizontal height. Threaded holes are designed on the small circular bosses 140 to facilitate the use of screws to fasten the optical platform 200 and the O-to-T test frame together.

[0029] A wire screw sleeve is embedded in the threaded hole of the circular small boss 140, so as to facilitate multiple disassembly of the screw without damaging the threaded hole.

[0030] The O-to-T test frame 100 has a lightweight design, with reinforcing ribs 150 designed at the load-bearing position and hollow grooves 160 opened at the non-load-bearing position. The shapes of the reinforcing ribs 150 and the hollow grooves 160 can be determined according to the designed bearing load.

[0031] In order to prevent the reinforcing ribs designed at the load-bearing position from being too thick, which may cause shrinkage and shrinkage during the casting process, grooves 170 may be reasonably added according to the actual casting thickness and the fluidity of the casting material, which is not the only restriction. The parts are connected by screws, and the parts have good processing technology, short production cycle, fast assembly speed, etc.

[0032] The optical platform 200 can move in the horizontal direction of the O-to-T test frame 100 , and the O-to-T test frame 100 is assembled together by screws 300 .

[0033] The installation method of the O-to-T combination test tooling for the test turntable of this embodiment is as follows:

[0034] S1, the O-to-T test frame 100 is positioned with the O-type turntable through pins;

[0035] S2, fasten the O-to-T test frame 100 and the O-type turntable with fastening screws;
