Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of three-temperature testing, in particular to a floating structure used for three-temperature testing of a testing machine. Background Art
[0002] Tri-temperature testing, also known as tri-temperature screening or tri-temperature stress screening, is a reliability testing method used to evaluate product performance stability and reliability in three different temperature environments: high, room, and low. This method is widely used in electronics, semiconductor devices, aerospace equipment, and other fields to ensure that products maintain normal operation under various extreme operating conditions.
[0003] However, the three-temperature test structures of test machines at home and abroad currently do not consider the floating and sealing problems. The present invention solves the floating and sealing problems in the three-temperature test of the test machine. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a floating structure for three-temperature testing of a testing machine, which has a simple structure and is safe and reliable. The three-temperature blowing device meets the pressure maintenance and air tightness requirements in the three-temperature test, filling the gap in this aspect of domestic testing machines.
[0005] In order to solve the above technical problems, the utility model provides a floating structure for three-temperature testing of a testing machine, including a floating structure, wherein the floating structure is arranged on a sheet metal box, and a reinforcement component is arranged on the other side of the sheet metal box; the floating structure includes a fixed shaft sleeve and a floating shaft, a first clamping groove is arranged on the upper part of the floating shaft, a sealing ring is arranged in the first clamping groove, a wave spring is arranged around the shaft body at the bottom of the side surface of the floating shaft and a second clamping groove is arranged at the bottom, a retaining spring is arranged in the second clamping groove, a wave spring is arranged in the fixed shaft sleeve, and a pneumatic quick-plug joint is arranged at the bottom of the floating shaft.
[0006] Furthermore, the pneumatic quick-connect elbow is connected to an external air source input pipe.
[0007] Furthermore, the pneumatic quick-connect elbow and the floating shaft are connected by threaded connection.
[0008] Furthermore, a center hole is provided on the sheet metal box at a position corresponding to the floating structure, and the floating structure is fixed to the sheet metal box by flange nuts.
[0009] Furthermore, the reinforcement component is pressed tightly against the sealing ring.
[0010] Furthermore, the structure of the sealing ring is an O-type structure.
[0011] The beneficial effects of the present invention are as follows: the air source input pipe of the device is inserted into the pneumatic quick-plug elbow of the floating structure, and the floating structure is fixed to the central opening of the sheet metal box by a flange nut, so that the floating shaft end of the floating structure extends from the central opening. When in working condition, the reinforcement component is pressed onto the floating structure by the working pressure of the testing machine, and the reinforcement component and the O-type sealing ring are pressed tightly. The floating shaft obtains continuous force through the compressed wave spring to press the O-type sealing ring and the reinforcement component to achieve sealing between the two. After the gas is input into the air source input pipe, the gas directly enters the reinforcement component without leakage, which can ensure pressure maintenance and airtightness during the three-temperature test, and has good use effect.
