Problems solved by technology

[0004] However, as far as the parts assembly of the traditional tubular structure is concerned, when welding two tubular or columnar parts, it is necessary to adjust and maintain the positional relationship between the two parts during the docking process of the two parts. When the docking positioning tool is used, it is inconvenient to adjust the docking coaxiality between the two parts. Inaccurate alignment will cause a large deviation in the coaxiality of the two workpieces after welding and assembly, resulting in a decrease in the accuracy of the instrument and affecting welding strength

Abstract

The invention provides a high-precision instrument welding clamping mechanism, which relates to the technical field of high-precision instrument manufacturing. A centering driver is fixedly connected to the bottom of the main frame body; it has the function of measuring and limiting the workpiece at the docking position. Through the centering mechanism, the direction and position of the tooling and the docking position can be accurately determined, and the axis position of the workpiece of the cylindrical structure can be determined. , to fix the position and direction of the spliced ​​parts, and to accurately adjust the coaxiality of the two connecting parts, further improve the assembly process, and solve the need to adjust and maintain the positional relationship between the two parts in terms of the current traditional tubular structure parts assembly. When the existing positioning tooling for butt joint of cylindrical parts is used, the inaccurate centering will cause a large deviation of the coaxiality of the two workpieces after welding and assembly, which will reduce the accuracy of the instrument and affect the welding strength.

Description

technical field [0001] The invention relates to the technical field of high-precision instrument manufacturing, in particular to a high-precision instrument welding clamping mechanism. Background technique [0002] In the assembly and manufacturing process of high-precision instruments, in order to make the instrument have high precision, it is necessary to ensure high assembly accuracy during the assembly process of the instrument. The connections between them include welding, gluing, bolting, etc. While it is necessary to ensure the strength between the assembled parts, it is also necessary to ensure the precise positional relationship of the assembled components, such as parallelism, perpendicularity, coaxiality, etc. , the positional relationship of the assembled parts may have a great impact on the accuracy of the instrument. [0003] For example, a patent with publication number CN212095105U discloses a high-precision instrument welding clamping mechanism, including a...
