Problems solved by technology

[0008] (1) Basically, it is for off-axis turning of off-axis aspheric surfaces. The off-axis installation position of the workpiece must meet the offset position of the off-axis aspheric surface, which is not suitable for off-axis turning of other types of free-form surfaces;
[0009] (2) After the workpiece is clamped on the substrate, the precise adjustment of the installation posture cannot be performed, especially the linkage adjustment of workpieces in different directions cannot be realized

specific Embodiment approach

[0054] According to the accompanying drawings, the specific implementation of the fixture assembly that realizes the function of the present invention is as follows:

[0055] (1) Put the three-wedge-surface linkage push rod 8 into the center hole of the attitude adjustment linkage push rod 11 first, and position it with the positioning key 8a to prevent the circumferential rotation;

[0056] (2) Put the posture adjustment linkage push rod 11 into the center hole of the clamp body body 2, and also use the positioning key 11a for circumferential positioning;

[0057] (3) Install the position adjustment and locking mechanism 9 and the attitude adjustment and locking mechanism 10 in the appropriate parts of the jig body 2 in sequence; finally install the parallel posture movement mechanism 5a, 5b, 5c and centrifugal force on the front end of the jig body 2 Flyweight 1 3a, centrifugal force flyweight 2 3b, centrifugal force flyweight 3 3c and clamping plates 4a, 4b, 4c, 4d, 4e, 4f,...

Abstract

The invention relates to an off-axis turning clamp capable of regulating position and pose precisely and belongs to the technical field of ultraprecise processing, optical part processing and the like. Parallel position and pose changing mechanisms which are arranged uniformly in a peripheral direction are used to realize the position and pose change of an off-axis free-form surface workpiece; a precision pinion and rack mechanism is used to perform precise linked position and pose regulation; and a manual pre-clamping and centrifugally automatic clamping combined mechanism is used to realizethe clamping and position and pose relocking of the workpiece. The clamp has the advantages that: the need of using a blank parent stock as a substrate is obviated; waste is reduced; off-axis amount can be regulated; processing flexibility is high; the regulation of the off-axis mounting position of the free-form surface can be realized; the pose regulation can be realized; the position and pose regulation is realized by linkage; the position and pose precision and synchronization can be ensured; and the device is simple and reliable and can greatly reduce the non-rotary symmetry during the processing of the off-axis free-form surface workpiece.

Description

technical field [0001] The invention belongs to the technical field of ultra-precision machining and optical parts processing, and relates to an off-axis turning fixture for precisely adjusting the posture and posture, which can realize precise linkage adjustment of the off-axis installation position and posture of free-form surface workpieces. Background technique [0002] Compared with traditional rotationally symmetrical optical surfaces, optical free-form surfaces have many excellent properties, such as overcoming various aberrations of the optical system, improving optical performance, reducing the size of the optical system, and reducing the weight of the optical system. Optical freeform surfaces not only have important applications in industrial fields such as aerospace and defense, but also have a wide range of application requirements in consumer-oriented industrial fields. At present, the processing methods for optical free-form surfaces mainly involve: replication...
