Problems solved by technology

[0003] At present, the inventors have found that the main problem of the thin film restrictor is that the thick film is very thin, it is easy to deform during processing and manufacturing, and it is difficult to process flat
Moreover, it is difficult to accurately calculate the amount of bending deformation produced by the film under force during use, which brings great difficulties to the design and calculation of the throttle gap and throttle ratio.
[0004] Moreover, in the prior art, whether it is a thin-film restrictor or a thick-film restrictor, the common problem is that the valve body and the throttle thick film need to be processed separately, the processing method is relatively complicated, and it is not easy to process. The throttle gap on both sides of the membrane is difficult to ensure consistency

Abstract

The invention discloses an integral flexural hinge thick-film throttler machining method. By means of the method, the problems that thin film in the prior art is quite prone to machining deformation,initial throttling clearances in the two sides are hard to be guaranteed to be consistent, and the throttling clearances are difficult to calculate after stress deformation are solved. The method hasthe beneficial effects that clearances in the two sides of thick film are guaranteed to be consistent, and thick film translational regulation is achieved. The scheme of the method is as follows: theintegral flexural hinge thick-film throttler machining method comprises the steps that a first through hole is drilled in a valve body, and a cutting wire is arranged in the first through hole in a penetrating mode; a flexural hinge profile, an oil inlet cavity profile, a throttling clearance profile and an oil outlet cavity profile on one side and a flexural hinge profile on the other side are cut in sequence; after cutting is completed, the cutting wire exits the first through hole; a second through hole is drilled in the valve body, and the structure of the other half of the valve body is machined; and oil inlet holes and oil outlet holes are machined in the oil inlet cavity profile and the oil outlet cavity profile which are already machined correspondingly.

Description

technical field [0001] The invention relates to the field of static pressure technology, in particular to a processing method for an integral flexible hinge thick film restrictor. Background technique [0002] Hydrostatic technology is widely used in precision machinery, and hydrostatic guide rails, hydrostatic bearings, and hydrostatic screw screws are typical application examples. The restrictor is a key component in these static pressure equipment, and its performance has an important influence on these static pressure equipment. There are four types of restrictors that are widely used: capillary restrictors, small hole restrictors, slide valve restrictors and film restrictors; among them, film restrictors are the most widely used, and are divided into single Throttling film on one side and two-sided film throttling. [0003] At present, the inventors have found that the main problem of the thin film restrictor is that the thick film is very thin, which is easily deform...
