Embodiment Construction

[0022] Such as image 3 , Figure 4 As shown, a flexible structure of a quartz lamp heater includes: a flexible connection tool 12, a movable clamp 15; the movable clamp 15 includes a fastener 16 and a chuck 17;

[0023] According to the size and shape of the test piece, bend the flexible connection tool 12 into a shape and size similar to that of the test piece, install several movable fixtures 15 in the chute 13 of the flexible connection tool 12, adjust the distance value, and use a tight Firmware 16 is fixed at equal intervals.

[0024] The structure of the flexible connection tooling 12 is as follows: Figure 5 As shown, the flexible connection tooling 12 is in the shape of a strip, and is made of stainless steel plates with a thickness of 0.002 to 0.005 m. Generally, the length is not greater than 1 m and the width is not greater than 0.03 m. Due to its thin thickness, the flexible connection tool 12 can have strong flexibility under the premise of a certain rigidity,...

Abstract

A quartz lamp heater flexible structure comprises a flexible connection tool (12) and a movable fastening tool (15), the flexible connection tool (12) has a long strip shape, and a long strip-like chute (13) is arranged at a center line along a length direction. The movable fastening tool (15) comprises a fastening member (16) and a fastening head (17), the fastening head (17) is installed in the chute (13) via the fastening member (16) on the tail undersurface and slides in the chute (13), and the head of the fastening head (17) tightly clamps one end of a quartz burner. The quartz burner is fixed between two flexible connection tools (12) via the movable fastening tools (15) located on different flexible connection tools (12), and the flexible connection tool (12) is connected with and fixed to a heater support (7). According to the present invention, the problem that a heater is difficult to arranged on a miniature special-shaped test piece is solved, the heating uniformity of a plurality of heated surfaces of different appearance test pieces is improved effectively, the test quality is improved, and the test cost and the test cycle are reduced.

Description

technical field [0001] The invention relates to a quartz lamp heater structure. Background technique [0002] Quartz lamp heater, as one of the indispensable equipment for ground thermal protection test, has been applied in major aerospace research institutes and universities in China. With the development trend of miniaturization of the overall structure of the aircraft and irregular shape of the aerodynamic shape, in order to make reasonable use of the internal space of the aircraft, designers have carried out miniaturization and special-shaped design of the internal equipment of the aircraft. Since the heating surface of miniaturized special-shaped equipment is often small in area and complex in shape, and the size of the existing heater is large, it is difficult to realize the independent heater arrangement for each heating surface, and it is impossible to adjust the thermal load conditions required for different heating surfaces (according to the test It is specificall...
