Embodiment Construction

[0035] Such as figure 1 As shown, the adjustment device provided by the embodiment of the present application includes a screw adjustment assembly 10, a nut adjustment assembly 20 and a connecting bracket 30, and the connecting bracket 30 is installed on the top surface of the nut adjustment assembly 20 through a bolt structure. The screw adjustment assembly 10 is fixed on the top surface of the connecting bracket 30 by bolts, so that the front end of the screw adjustment assembly 10 penetrates into the hollow structure of the nut adjustment assembly 20, and the screw adjustment assembly 10 and the nut adjustment assembly 20 form a concentric structure. , the screw adjusting assembly 10 and the nut adjusting assembly 20 operate independently, forming a concentric rotating structure.

[0036] The adjustment device also includes a protective cover 50, the screw adjustment assembly 10, the connection assembly 30 and the nut adjustment assembly 20 are arranged in the protective co...

Abstract

The invention is suitable for the technical field of concentric double-shaft tool clamps, and provides an adjusting device. The adjusting device comprises a screw adjusting assembly, a nut locking assembly and a connecting support. The nut locking assembly and the screw adjusting assembly are connected together through the connecting support. The nut locking assembly is arranged on the screw rod adjusting assembly in a sleeving manner; the nut locking assembly and the screw adjusting assembly form two rotating structures which operate independently and are concentric, the screw and the nut areadjusted and locked through the independent concentric rotating shafts, the two rotating shafts which operate independently and coaxially in the same direction are achieved, and the position, the rotating speed and the torsion of each shaft can be controlled independently.

Description

technical field [0001] The application relates to the technical field of concentric two-axis fixtures, in particular to an adjustment device and tuning equipment used on filters. Background technique [0002] The cavity filter is cut from metal as a whole. It is widely used because of its advantages such as firm structure, stable performance, small size and moderate Q value. After the production and assembly are completed, the cavity filter needs to be tuned. The length of the body is used to adjust the resonant frequency of the cavity filter to achieve the performance index required by the cavity filter. After the screw is adjusted in place, the nut needs to be locked to achieve its performance index. [0003] In the prior art, the tuning screw is locked by manually locking the nut. When manually locking the screw and nut, the left and right hands need to cooperate with each other. One hand holds a screwdriver to adjust the height of the screw, and the other holds a socket ...
