DETAILED DESCRIPTION

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

[0022] Referring to Figs. 1 to 3The O-turn-T test tool for testing the turntable comprises an O-turn-T test frame 100, an optical platform 200 and a screw 300. The O-turn-T test frame 100 is positioned by a pin and fastened with the O-turn table by a fastening screw. The optical platform 200 is fixed on the O-turn-T test frame 100 by the screw 300. The product to be tested is placed on the optical platform 200 for adjustment and test.

[0023] The O-turn-T test frame 100 is cast from cast aluminum alloy. The optical platform 200 is a general optical platform sold on the market. The screw 300 is preferably an internal hexagonal cylindrical head screw.

[0024] The O-turn-T test frame 100 comprises a circular flange surface and a flange ring 130 located inside the flange surface. The flange surface is mounted in close contact with the end surface of the O-turn table. The flange ring 130 is matched with the inner wall of the O-turn table.

[0025] Eight evenly distributed threaded holes 120 and two symmetrically distributed pin holes 110 are arranged on the flange surface. The pin holes 110 are aligned with the positioning holes on the O-turn table to ensure that the O-turn-T test frame 100 and the O-turn table are aligned as concentric circles. The threaded holes 120 are used to pass through the screws to fasten and install the O-turn-T test frame 100 and the O-turn table together.

[0026] The flange ring is used to co-form with the inner circle of the O-turn table and plays a guiding and auxiliary installation role.

[0027] The O-turn-T test frame 100 further comprises a horizontal surface located in the circular inner cavity of the flange surface and perpendicular to the flange surface. The optical platform 200 is installed on the horizontal surface.

[0028] The horizontal surface is designed with multiple circular small bosses 140. The circular small bosses 140 maintain consistent horizontal height. Threaded holes are designed on the circular small bosses 140 to facilitate the fastening and installation of the optical platform 200 and the O-turn-T test frame together by screws.

[0029] Steel wire bushings are embedded in the threaded holes of the circular small bosses 140 to facilitate the repeated disassembly of the screws, thereby not damaging the threaded holes.

[0030] The O-turn-T test frame 100 has a lightweight design. Reinforcing ribs 150 are designed at the load-bearing positions. Hollow grooves 160 are provided at non-load-bearing positions. The shapes of the reinforcing ribs 150 and the hollow grooves 160 can be determined according to the designed load bearing.

[0031] To prevent the reinforcing ribs designed at the load-bearing positions from being too thick and causing shrinkage and shrinkage hole phenomena during casting, recesses 170 can be reasonably added according to the actual thickness of the casting and the fluidity of the casting material. This is not the only limitation. The parts are connected by screws, and the part machining process is good, with the advantages of short production cycle and fast assembly speed.

[0032] The optical platform 200 can move horizontally in the O-T test fixture 100 and is assembled together by screws 300.

[0033] The installation process of the O-to-T combined test fixture used for the test turntable in this embodiment is as follows:

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

[0035] S2. Secure the O-turn test fixture 100 to the O-type turntable using fastening screws;

[0036] S3. Fix the optical platform 200 onto the O-to-T test fixture 100 using screws 300;

[0037] S4. Place the product under test on the optical platform 200 for adjustment and testing.

[0038] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
