Embodiment Construction

[0018] See figure 1 , The entire four-degree-of-freedom fine-tuning device is installed on the platform 1.

[0019] The horizontal moving table 8 (10) is mainly composed of the motor 13, the lead screw 2, the guide rail 3, and the sliding plate 4. Through the preset stroke, the measurement and transmission of the lead screw are used to control the motor 13 to drive the lead screw 2 to rotate. The sliding plate 4 is driven to move on the guide rail 3. This device greatly improves the mobility of the device system, and is especially suitable for precision installation of large systems. When the degree of freedom is not high, this horizontal mobile station can be used individually and adopt a suitable installation method.

[0020] See figure 2 , 2*3 cones are distributed on both sides of the sliding plate 4 (6). Through the measurement of the joint arm coordinates, the coordinates can be determined, and the movement and rotation of the two water platforms and the rotating table can ...

Abstract

The invention discloses a four-freedom-degree fine adjustment device comprising a horizontal moving table erected on a platform, and the horizontal moving table comprises a sliding rail, a lower sliding plate is matched with the sliding rail in a sliding mode, a scissor type lifting table is arranged on the lower sliding plate and comprises an upper fixing plate and a lower fixing plate, four equilateral quadrangles in two row and two column are correspondingly matched, and the two opposite top ends of the equilateral quadrangles are fixed to the upper fixing plate and the lower fixing plate, and the other two top ends and the corresponding top ends of the equilateral quadrangles on the same column are connected together through transverse rods in a pairwise mode. A rotating disc is arranged at the upper end of the upper fixing plate of the scissor type lifting table, a horizontal moving platform is placed on the rotating disc, clamping devices are distributed on the upper end face of the upper sliding plate, and two rows and three columns of conical nests corresponding to one another are respectively distributed in the two sides of the upper sliding plate and the two sides of the lower sliding plate. The fine adjustment device is high in positioning precision, convenient to operate and capable of precisely installing different parts and also achieving delimiting of a scale mark at any position.

Description

Technical field [0001] The invention relates to a four-degree-of-freedom fine-tuning device, in particular to a fine-tuning device for assembling internal parts of an EAST device and marking the graduation line. Background technique [0002] During the renovation of the EAST device, the precise assembly of internal parts has always been a major problem in the installation process. First, due to the limitation of the device's own structure, it is impossible to use a total station or theodolite to draw the graduation line at any position in the vacuum chamber of the EAST device on the walls around the device hall and on the dewar outside the device. set. Second, since the weft ring and guide rails inside the device are the benchmarks for the installation of other parts, the installation accuracy is very critical. Using traditional tooling and installation methods, it is difficult to ensure the accuracy of the installation of the parts, the installation efficiency is relatively lo...
