Embodiment Construction

[0029] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0030] like Figure 1-Figure 3 As shown, a fast knife structure using an air static pressure guide rail in the present invention includes a motor, an air static pressure guide rail group, a tool assembly and a measuring assembly.

[0031] The motor is a voice coil motor. The voice coil motor has the advantages of large output force, high speed and acceleration, and large stroke. It can realize the high-frequency response required for the processing of complex microstructure parts, and can also meet the processing of high-steep and complex surface shapes. The required large travel requirements. The motor includes a stator 3 and a mover 4 . The stator 3 is installed on the stator base 2, and a stator water jacket 1 is arranged outside the stator 3. The stator water jacket 1 is used to cool the motor. The stator water jacket 1 is provi...

Abstract

The invention relates to the technical field of precision instrument manufacturing, and aims at providing a high-efficiency, high-precision and low-cost sharp knife structure adopting air hydrostatic guideways. The sharp knife structure adopting the air hydrostatic guideways comprises a motor, an air hydrostatic guideway set, a knife assembly and a measuring assembly. The motor is a voice coil motor and comprises a stator and a mover. The air hydrostatic guideway set is fixedly connected with the mover of the motor and comprises a first air floating sharp knife guideway and a second air floating sharp knife guideway. The first air floating sharp knife guideway is arranged vertically, the second air floating sharp knife guideway is arranged horizontally, and a T-type structure is formed by the two air floating sharp knife guideways. A T-type cavity is formed by air floating blocks on the outer side of the air hydrostatic guideway set. The knife assembly comprises a knife. The measuring assembly comprises a grating ruler and a reading head, the grating ruler is mounted above the air hydrostatic guideway set, and the reading head is fixed to a reading head support and is located above the grating ruler.

Description

technical field [0001] The invention relates to the technical field of precision instrument manufacturing, in particular to a fast knife structure for processing micro-optical elements. Background technique [0002] Optical microstructures are widely used in military and civilian industries, and are closely related to production and life. In view of its wide application and huge role, fast tool servo turning has developed rapidly. Fast tool servo turning can meet the requirements of high precision and high efficiency of ultra-precision machining at the same time, and is an effective way to solve the processing difficulties of microstructured optical components. All countries have invested a lot of manpower and material resources in the fast tool servo turning technology in order to occupy the technical high ground. [0003] Since the surface of the microstructured optical element is a high-precision, asymmetric surface with complex shape, traditional processing methods such...
