Problems solved by technology

However, the disadvantage of the U-T frame is that the U-frame is weak in rigidity and is usually made of iron alloy. As a result, the frame form does not significantly reduce the weight and moment of inertia due to the reduced volume, which has no effect on the selection and cost reduction of the motor. Significant advantage

Embodiment Construction

[0012] The technical scheme of the present invention will be described in further detail below in conjunction with accompanying drawing and embodiment:

[0013] The UO-T composite frame structure used for the turntable includes a T-shaped roll frame 2 and a U-shaped pitch frame 5. The roll frame 2 directly drives the load to roll and rotate, and the pitch axis of the U-shaped pitch frame 5 Fix on the base 1, fix a closed O-shaped frame 3 on the U-shaped opening end of the U-shaped pitching frame 5, the distance between the U-shaped pitching frame 5U-shaped opening ends is 800mm, and the O-shaped frame 3 is a hollow structure Octagonal, made of steel or aluminum with a height of 50-60mm and a width of 100-110mm, the plane of the O-shaped frame 3 is perpendicular to the plane of the U-shaped pitch frame 5, and is installed on the closed O-shaped frame 3 The counterweight 4 is used to adjust the center of gravity of the U-shaped pitch frame 5 on the pitch axis of the U-shaped pit...

Abstract

The invention relates to a UO-T composite frame structure for a rotary table. The frame structure comprises a roll frame(2) with a T-shaped structure, a U-shaped pitching frame (5), the roll frame(2)directly drives the load to carry out roll rotation, a pitch axis of the U-shaped pitching frame (5) is fixedly arranged on the base, the U-shaped pitching frame has characterized in that the U-shapedpitching frame (5) closed an O-shaped frame(3) is fixed on the U-shaped opening end, the plane where the O-shaped frame(3) is located is perpendicular to the plane where the U-shaped pitching frame(5) is located. The frame structure solves the problem that an U-T composite frame is insufficient in rigidity and cannot be applied to a high-precision rotary table, and meanwhile, an O-O type framework of the high-precision rotary table is more economical.

Description

technical field [0001] The invention is a UO-T composite frame structure used for a turntable, which belongs to the field of inertial navigation test and is used for inertial navigation test, calibration or flight state simulation turntable. Background technique [0002] The inertial navigation test and motion simulation (simulation) test equipment is mainly used for the performance test of the inertial measurement unit (IMU) and the inertial navigation system (INS) and the attitude motion simulation (simulation) test of the carrier. And use the indispensable ground test equipment in the maintenance process. In terms of platform structure, a symmetrical frame structure with precision mechanical shaft support and torque motor direct drive is generally used, and the rigidity and precision of the structure are effectively improved through optimized design, selection of new materials and precise processing adjustment technology. [0003] The pitch frame and roll frame of the hi...
