Small heavy-duty multi-degree-of-freedom adjustment device

Abstract

The invention discloses a small heavy-load multi-degree-of-freedom adjusting device and relates to the technical field of testing equipment. The small heavy-load multi-degree-of-freedom adjusting device comprises a bottom fixing platform, a horizontal moving assembly, a vertical moving assembly and an object bearing table. A moving platform is arranged on the bottom fixing platform, and the horizontal moving assembly comprises a first driving piece connected with the moving platform. The vertical moving assembly comprises a second driving piece connected with a second screw rod through a seat,the seat is fixed to the moving platform, and the tail end of the second screw rod is connected with a first wedge-shaped block. The object bearing table is vertically movably arranged on the movingplatform in an assembled mode, and the bottom of the object bearing table abuts against the oblique face of the first wedge-shaped block. Meanwhile, the seat comprises a screw rod ball piece, the second screw rod is arranged on the screw rod ball piece in a penetrating mode, and the screw rod ball piece is arranged on the second driving piece in a sleeving mode, and slidably connected to the second driving piece. According to the small heavy-load multi-degree-of-freedom adjusting device, the size is small, and the horizontal direction and the vertical direction can be adjusted under the situation of mutual noninterference.

Description

technical field [0001] The invention relates to the technical field of testing equipment, in particular to a small heavy-duty multi-degree-of-freedom adjustment device. Background technique [0002] With the development of science and technology, the test requirements for the development of heavy-duty products are getting higher and higher. The demand for multi-degree-of-freedom precise adjustment during the test process has derived various multi-degree-of-freedom stages and stage adjustment devices. High-precision , The demand for multi-degree-of-freedom adjustment devices is also increasing. The existing regulating device has simple functions and cannot meet the adjustment requirements of existing laboratories. [0003] Most of the heavy-load stage adjustment devices have simple functions and a single adjustment method, which cannot meet the multi-degree-of-freedom adjustment requirements of the existing test process, and cannot adjust the displacement in the horizontal a...

The existing adjustment device has simple functions and cannot meet the adjustment requirements of the existing laboratory

[0003] Most of the heavy-duty stage adjustment devices have simple functions and a single adjustment method, which cannot meet the multi-degree-of-freedom adjustment requirements of the existing test process, and cannot adjust the displacement of the horizontal and vertical degrees of freedom without interfering with each other.

At present, some heavy-duty stages can realize two-degree-of-freedom or three-degree-of-freedom adjustments, but the adjustment accuracy is not precise enough to accurately make corresponding displacement adjustments according to requirements. The actual adjustment can only be determined by manual measurement and other methods. , and the carrying capacity of the stage is small or the space volume is large, which cannot meet the carrying requirements or space requirements of various heavy-duty products
