Attitude adjusting device appropriate for rotary workpieces

Abstract

The invention provides an attitude adjusting device appropriate for rotary workpieces, which comprises a product clamping and adjusting device and a rotary table, and the product clamping and adjusting device is connected with the rotary table by a linear guide rail, thereby ensuring that the product clamping and adjusting device can move on the rotary table, so that a front detector of a rotary workpiece can always be arranged at the center of the rotary table. The product clamping and adjusting device is in the structure of combining a stepped sleeve with an adjustable support assembly, therefore, the heights of the clamping centers of the rotary workpieces in different outer diameters can be consistent; and the stepped sleeve is fixed on an external cylinder by a roller and can perform360-degree horizontal rolling; and a pitching adjusting assembly can complete the pitching adjustment of the rotary workpieces. The rotary table is a precise rotary table, and can realize the + / - 180-degree horizontal rotary adjustment of the rotary workpieces. The attitude adjusting device can achieve the effects of clamping the rotary workpieces of three different outer diameters, and adjustingthe front detector to locate at the rotary center of the rotary table according to the rotary workpieces of different lengths. The attitude adjusting device can widely be applied to rotary workpiece or missile production enterprises, aerospace scientific research universities and institutions, and tubular workpiece production enterprises.

Description

technical field [0001] The invention relates to a posture adjusting device suitable for a rotary workpiece. Background technique [0002] Optical imaging systems are widely used in daily digital products, seekers and other fields, with very high sensitivity. [0003] While receiving the target image signal, the optical imaging system will also receive stray light signals from interference sources. These stray light signals will reduce the contrast of the image plane and the modulation transfer function, reducing the level of the entire picture, deteriorating the definition, and reducing the energy consumption. The distribution is chaotic and even stray light spots are formed. In severe cases, the target image signal is completely submerged by stray light, which directly affects the performance indicators of optical imaging systems (such as missile seekers or other tubular workpieces).

Problems solved by technology

[0003] While receiving the target image signal, the optical imaging system will also receive stray light signals from interference sources. These stray light signals will reduce the contrast of the image plane and the modulation transfer function, reducing the level of the entire picture, deteriorating the definition, and reducing the energy consumption. The distribution is chaotic and even stray light spots are formed. In severe cases, the target image signal is completely submerged by stray light, which directly affects the performance indicators of optical imaging systems (such as missile seekers or other tubular workpieces)

At present, the sensitivity of the infrared optical imaging system used in most air-to-air missiles is very high, and the requirements for image quality are getting higher and higher, which makes the rotary workpiece more sensitive to internal and external stray light interference. Stray light interference will directly affect the performance index of the seeker
