Positioning tool clamp for precision box-shaped sensor welding and using method of positioning tool clamp for precision box-shaped sensor welding

Abstract

The invention discloses a positioning tool clamp for precision box-shaped sensor welding and a using method of the positioning tool clamp for precision box-shaped sensor welding. An observation window is arranged in the center of an upper plate; radiating clamping devices are arranged at the positions, on the periphery of the observation window, on the lower surface of the upper plate, a stand column penetrates through a guide rail sleeve and penetrates through the upper plate, a middle plate and a lower plate, the two ends of the stand column are fixed to the upper plate and the lower plate respectively, and a spring is arranged at the position, between the vertical part of the middle plate and the vertical part of the lower plate, of the stand column. Compared with the prior art, according to the technical scheme, the spring, a rapid clamp and the radiating clamping devices are jointly matched to complete clamping of a box-shaped sensor body and a cover plate assembly, and therefore relative slippage of the box-shaped sensor body and the cover plate assembly can be avoided; the radiating clamping devices are adopted, heat conduction in the welding process can be achieved while the clamping force is used, and therefore damage of welding heat to a box-shaped sensor is avoided; the direct observation window is arranged, the size required by welding is conveniently observed and adjusted.

Description

technical field [0001] The invention relates to a welding fixture, in particular to a positioning fixture for precision box-type sensor welding and a method for using the same. Background technique [0002] A precision box-shaped structure sensor is often a high-precision component sensor that can be used to detect information such as displacement, velocity, force, and acceleration. Sensor components are often machined multiple times from a variety of materials. The quality of the welding and forming of the final box-shaped component is directly related to the system accuracy and technical parameters of the entire sensor. At present, the positioning fixture used by the production unit has poor installation visibility and inaccurate positioning, and the relative slippage of the components will occur during the clamping process, which cannot guarantee the welding positioning accuracy requirements of the box-type sensor components, and the geometric dimensions of the component...
