Embodiment Construction

[0023] The present invention will be further elaborated below in conjunction with the accompanying drawings and embodiments.

[0024] Such as Figure 1 to Figure 4 As shown, a precision positioning platform with adjustable displacement includes: a base 1 for support and protection, which is installed on the precision optical vibration isolation platform through threaded holes evenly distributed around it, and is also processed on it for installing other parts. A number of threaded holes; a manual adjustable slide platform 2 that can be fine-tuned in the three degrees of freedom directions of X-axis, Y-axis displacement and R-axis rotation through cross-rotating guide rails. Four countersunk screws are fixed to the base 1, and several threaded holes are evenly distributed on the work surface; the platform pad 8 is installed on the platform working surface 14 on the adjustable frame displacement slide platform 2, and the support is flexible and the hinge is precise. The positio...

Abstract

The invention discloses a displacement-adjustable precision locating platform. The displacement-adjustable precision locating platform comprises a base, a manual adjustable frame sliding table platform, a platform cushion block, a compliant hinge precision locating platform body, four electromagnetic armatures, two Z-axis right-angle junction plates and electromagnetic drivers. The manual adjustable frame sliding table platform can achieve three-freedom-degree precision locating adjustment through a cross rotating guide rail. The platform cushion block is arranged on a sliding table through four evenly-distributed threaded holes. The middle of the compliant hinge precision locating platform body is fixed to the platform cushion block through two threaded holes, and therefore the platform can achieve displacement in the X-axis direction and Y-axis direction along with the manual adjustable frame sliding table platform. The four electromagnetic armatures are fixed in the four directions of the compliant hinge precision locating platform body in a threaded connection manner. The two Z-axis right-angle junction plates are in threaded connection with the base of the platform. The electromagnetic drivers serve as drive equipment of the platform and are in threaded connection with the Z-axis right-angle junction plates to be connected with the base of the platform. The displacement-adjustable precision locating platform is simple in structure, small in overall size, low in cost and convenient to operate, and the high-precision locating requirement can be met.

Description

technical field [0001] The invention belongs to the field of flexible and precise positioning, in particular to a precision positioning platform with adjustable displacement. Background technique [0002] Precision positioning technology has a wide range of applications in biomedical engineering, precision optical engineering, microelectronic systems, national defense technology and other fields, and has become an indispensable part of high-tech development. Precision positioning technology uses a high-precision drive device to drive the support structure to achieve positioning requirements. Compared with other positioning technologies, the flexible hinge precision positioning platform obtains the displacement output of the platform through electromagnetic drive. It has a simple structure, can eliminate the friction between the hinges and the return gap, and does not need lubrication. The advantages. For fields such as semiconductor lithography, micro-assembly, and bio...
