The invention discloses air tightness detection equipment for precision machining of aircraft parts, which comprises a workbench, a support frame is fixed in the middle of the workbench, two support seats slidably connected with the workbench are symmetrically arranged on two sides of the support frame, and electric telescopic rods are arranged on side surfaces of the support seats. The output ends of the electric telescopic rods are fixedly connected with the supporting bases, the electric telescopic rods are fixed to the workbench, supporting cylinders are fixed to the supporting bases, lantern rings are fixed to the opposite ends of the two supporting cylinders, and a plurality of sliding grooves are formed in the lantern rings. Through mutual cooperation of all the components, the arc-shaped pressing plate and the arc-shaped top plate are close to each other, the inner wall is supported while the outer side of the wall face of the end of the exhaust nozzle is extruded, the situation that the precision of the exhaust nozzle after detection is affected due to deformation caused by single-side stress of the exhaust nozzle is prevented, normal use after detection is guaranteed, and the detection efficiency is improved. The utilization rate is improved, the damage rate of inspection is reduced, and the cost is reduced.
本发明公开了一种飞机零部件精密加工用气密性检测设备,包括工作台,所述工作台中部固定有支撑架,所述支撑架两侧对称设有与工作台滑动连接的两个支撑座,所述支撑座侧面均设有电动伸缩杆,电动伸缩杆的输出端与支撑座固定连接,电动伸缩杆固定在工作台上,所述支撑座上均固定有支撑筒,两个所述支撑筒相对的一端均固定有套环,所述套环上开设有多个滑槽。本发明通过各个部件之间的相互协作,实现了弧形压板和弧形顶板的相互靠近并对尾喷管的端部的壁面的外侧挤压的同时,对内壁进行支撑,防止尾喷管单侧受力发生形变,影响尾喷管检测后的精度,保证检测后能够正常的使用,提高利用率,减小检验的损毁率,降低成本。
