Embodiment Construction
[0040] Attached below Figure 1-9 And specific embodiments further illustrate the present invention.
[0041] Such as Figure 1-4As shown, the four-degree-of-freedom fine-tuning bracket of the present invention includes a base plate 1, a middle adjustment plate 2, an upper adjustment plate 3, two linear clamping assemblies 4, four angle clamping assemblies 5, and four angle adjustment assemblies 6 and two linear adjustment assemblies 7. A linear adjustment assembly 7 and a linear clamping assembly 4 are respectively fixed along the X-axis direction and the Y-axis direction of the substrate 1. The linear adjustment assembly 7 and the linear clamping assembly 4 in the X-axis direction are symmetrical with respect to the Y-axis. The linear adjustment assembly 7 and the linear clamping assembly 4 are symmetrical with respect to the X axis; generally, the two linear clamping assemblies 4 and the two linear adjustment assemblies 7 are fixed on the edge of the upper surface of the ...

The invention discloses a four-degree-of-freedom fine adjustment support, and belongs to the technical field of fine adjusting mechanisms. The four-degree-of-freedom fine adjustment support solves the problems that in the prior art, a precision mechanical adjusting mechanism is large in size, poor in accuracy and frequent in adjustment times. The fine adjustment support mainly comprises a base plate, a middle adjustment plate, an upper adjustment plate, two straight line abutting assemblies, four angle clamping assemblies, four angle adjustment assemblies and two straight line adjustment assemblies. The straight line adjustment assemblies and the straight line abutting assemblies are fixed to the base plate and symmetrically arranged in pairs in the X direction and in the Y direction respectively, and the eccentric adjustment and positioning of the middle adjustment plate in the X direction and in the Y direction are achieved through the straight line adjustment assemblies and the straight line abutting assemblies; the angle adjustment assemblies fixed to the middle adjustment plate and the upper adjustment plate are evenly distributed in the X direction and in the Y direction respectively, the angle clamping assemblies and the angle adjustment assemblies are staggered by 45 degrees and then are evenly distributed. Angle adjustment locking of the middle adjustment plate and the upper adjustment plate is achieved through the angle clamping assemblies and the angle adjustment assemblies. The fine adjustment support is compact in structure and high in practicability, and fine adjustment is easy to conduct.
Description
technical field [0001] The invention belongs to the technical field of precision adjustment mechanisms, and in particular relates to a four-degree-of-freedom fine adjustment mechanism. Background technique [0002] In the process of optical-mechanical component integration and optical inspection, it is often necessary to slightly adjust the eccentricity and inclination of the installed optical-mechanical components to achieve the required technical indicators and meet the detection requirements. To accurately adjust the machine components to the specified position, the adjustment frame needs to be used and the following requirements must be met: [0003] 1. The overall dimensions of the adjustment frame should not be too large and the structure should be compact; [0004] 2. Try to avoid coupling between the corresponding adjustment dimensions of the adjustment frame; [0005] 3. The adjustment frame should be convenient, labor-saving, fast and have self-locking function w...
