Embodiment 1

[0028] refer to Figure 1 ~ Figure 3 As shown, a half-mould window turning mechanism includes a balance 1, a balance seat 2, a main wheel 8 and a housing 15.

[0029] The balance 1 is fixed on the balance seat 2, and the upper end of the balance is used to connect the model 18 to realize the fixation of the model on the balance and measure the force of the model. The outer cone surface at the lower end of the balance 1 fits the inner cone surface of the balance seat 2, and the balance 1 is connected to the balance seat 2 through screws, and the tension between the balance and the balance seat is realized through the bolts to ensure the tightness between the two cone surfaces Fitting, connecting the balance and the balance base as one.

[0030] Both the balance 1 and the balance base 2 are located in the main wheel 8, the balance base 2 is fixed with a lead screw nut 3, the lead screw nut 3 is threaded on the lead screw 4, and the lead screw 4 is rotated in the main wheel 8 th...

Abstract

The invention discloses a half-mold rotating window mechanism. The mechanism comprises a balance and a balance seat in a main wheel; the balance is arranged on the balance seat; a wedge block is tightly supported between the balance seat and the main wheel; and a tensioning assembly is arranged between the wedge block and the main wheel. According to the half-mold window rotating mechanism,the sliding adjustment of the balance seat is realized through a lead screw nut and a lead screw, and the axial positioning of the balance can be ensured; the wedge block is supported between the main wheel and the balance seat, so that the balance seat is effectively locked, and meanwhile, a block groove has a circumferential limiting effect; the lead screw assembly is located below the balance seat, the wedge block assembly is located above the balance seat, the two assemblies cooperate with each other, so that the sliding and fixing of the balance seat can be achieved, axial and circumferential displacement precision of the balance seat is guaranteed through the cooperation of the lead screw assembly and the wedge block assembly;and it is guaranteed that the overall structure of the mechanism is high in precision and stability.

Description

technical field [0001] The invention belongs to the technical field of aviation wind tunnel tests, and in particular relates to a half-molded window turning mechanism. Background technique [0002] In the field of experimental aerodynamics, the semi-model wind tunnel test technology developed according to the symmetrical layout and shape characteristics of various aircrafts is usually placed on the half-model support of the side wall observation window of the wind tunnel test section for testing. Therefore, in addition to the functions of supporting the model, installing the balance, changing the posture, and leading out the measurement and control signal pipeline, the half-model bracket (also known as the "half-model swivel window") should also have the ability to accurately adjust the lateral Displacement and always maintain high-precision matching requirements between the balance seat-half-mould balance-half-model and reliable locking capabilities at limited positions. ...
