Assembling method for inner frame assembly of three-axis rotary table

Abstract

The invention discloses an assembling method for an inner frame assembly of a three-axis rotary table. The inner frame assembly of the three-axis rotary table comprises an inner frame, a first inner frame trunnion, a second inner frame trunnion, four product mounting blocks and abutting pins. The method specifically comprises the steps that the first inner frame trunnion and the second inner frametrunnion are symmetrically arranged in mounting holes of the inner frame; the inner frame is placed on a V-shaped frame and is rotated, and the degree of parallelism of the first inner frame trunnionand the second inner frame trunnion is adjusted to meet the requirement; the inner frame is placed on a marble platform, and the first inner frame trunnion and the second inner frame trunnion are scrapped and ground, so that the axes of the first inner frame trunnion and the second inner frame trunnion are at equal height; four bosses on the inner frame are scrapped and ground so as to meet the coplanarity requirement; the four product mounting blocks are arranged; the inner frame assembly is placed on a workbench of a machining machine tool, abutting pin holes are machined, and threaded holes are machined; and the abutting pins are pressed into the abutting pin holes. The method has the advantages that the precision in the assembling process of the product mounting blocks of the inner frame has the examinability, the operation is convenient and visual, the positioning precision is high, the stability of the inner frame assembly can be improved, and the assembling efficiency can be improved.

Description

technical field [0001] The invention relates to a combined assembly method for an inner frame assembly of a three-axis turntable, belonging to the field of precision mechanical assembly. Background technique [0002] The turntable is a device for calibrating, testing and inspecting the precision of inertial devices, which requires high precision. The inner frame assembly is one of the important components of the turntable, mainly composed of the inner frame, inner frame trunnions, four product mounting blocks, and three pins. The inertial device is installed on the inner frame assembly, the position is guaranteed by the pin, and fixed through the threaded hole on the product installation block. In order to ensure the test accuracy of the inertial device, under the premise of ensuring the high precision of the turntable, it is necessary to ensure the coplanarity of the four product mounting blocks on the inner frame assembly, the parallelism of the product mounting block to ...
