Description

Technical Field

[0001] The invention relates to the technical field of test chambers, in particular to an environmental simulation four-integrated test chamber. Background Art

[0002] The environmental simulation four-in-one chamber is a high-end reliability testing equipment that can simultaneously simulate four environmental factors: temperature, humidity, air pressure (vacuum / positive pressure), and vibration. It is mainly used in aerospace, electronics, automotive and other fields to verify the performance stability of products under the coupling of complex environments.

[0003] However, traditional test chambers are installed by hoisting or fork-mounting. After being hoisted onto the lifting frame, the position needs to be repeatedly adjusted manually to align the connection base at the bottom of the test chamber with the screw holes on the lifting platform. Due to the large size and weight of the test chamber, the position adjustment of the test chamber is time-consuming, and the positioning accuracy is insufficient, resulting in low installation efficiency.

[0004] The installation of a traditional test chamber's flexible connector requires manual alignment of the chamber and the vibration table interface. During manual loading, it's difficult to precisely control the position and pressure of the flexible connector, which can cause gasket deformation or metal frame misalignment, affecting the chamber's airtightness.

[0005] The carrier of a traditional test chamber is hidden inside the cavity, requiring the operator to reach into the cavity to secure the workpiece. This limits the operating space and is inefficient. The carrier lacks a convenient pull-out and push-in mechanism, and the workpiece is prone to shaking during the securing process, resulting in positioning deviations. Manual adjustments can cause damage to heavy or delicate workpieces, especially those that are prone to collisions.

[0006] The central fixing platform of the traditional test chamber soft connection device lacks reliable fixation when loading workpieces, and is prone to shaking due to operation and touch, affecting the loading accuracy. Traditional fixing methods (such as bolt tightening) require point-by-point installation, which is time-consuming and labor-intensive, resulting in low loading efficiency. Summary of the Invention
