Embodiment 1

[0044]This embodiment is a leveling device for a disc-shaped plate, including a hydraulic cylinder 1, a gantry frame 2, a furnace body 11, a heat preservation furnace lining 12, an electric furnace wire 14, a hydraulic cylinder piston 16, an upper pressure head 17, a thermocouple 18, a lower Indenter 20, parallelism adjustment table 21, bearing column 22 and furnace body base 23.

[0045] Gantry 2 is the carrier of the present embodiment. The portal frame 2 is a frame structure, including a pillar, an upper beam, a furnace body mounting platform 28 and a portal frame base. The upper beam and the furnace body installation platform 28 are rectangular. Between the upper crossbeam and the body of furnace installation platform 28, it is supported by a pillar, and the base is installed on the lower crossbeam for supporting the whole device.

[0046] There is a hydraulic cylinder installation hole at the geometric center of the upper beam, and the hydraulic cylinder 1 is fixed in t...

Embodiment 2

[0059] This embodiment is a method for leveling the brake disc frame of a certain type of aircraft by using the disc leveling device described in Example 1. The specific process is:

[0060] Step 1, install the brake disc frame 27 and backing plate 26 of the aircraft to be leveled. Such as image 3 As shown, first unscrew the C-shaped clamp 4, open the furnace door, lift the upper pressure head 17 through the external hydraulic control system, adjust the relay in the control cabinet to control the hydraulic valve in the hydraulic station, and discharge oil and pressure on the hydraulic cylinder 1 , so that the hydraulic cylinder piston 16 drives the upper pressure head 17 to lift 260mm according to the number of required leveling workpieces, then place a backing plate 26 on the lower pressure head 20, and then place a piece of aircraft brake disc to be leveled in the middle of the backing plate 26 in turn Skeleton27. During installation, the backing plate 26, the aircraft br...

Embodiment 3

[0072] This embodiment is a method for leveling the brake disc skeleton of a certain type of aircraft. The specific process is:

[0073] Step 1, install the brake disc frame 27 and backing plate 26 of the aircraft to be leveled. Such as image 3 As shown, first unscrew the C-shaped clamp 4, open the furnace door, lift the upper pressure head 17 through the external hydraulic control system, adjust the relay in the control cabinet to control the hydraulic valve in the hydraulic station, and discharge oil and pressure on the hydraulic cylinder 1 , so that the hydraulic cylinder piston 16 drives the upper pressure head 17 to lift, and the lifting height of the upper pressure head is determined according to the number of required leveling workpieces. A backing plate 26 is placed on the lower pressing head 20, and a piece of aircraft brake disc skeleton 27 to be leveled is placed in the middle of the backing plate 26 successively. During installation, the backing plate 26, the ai...

Abstract

The invention relates to a disc-shaped panel leveling device and a disc-shaped panel leveling method. A furnace body of the disc-shaped panel leveling device is positioned in a portal frame and is fixed on a furnace body mounting table of the portal frame. A hydraulic cylinder is fixed on an upper beam of the furnace body. The lower end of a hydraulic cylinder piston of the hydraulic cylinder is inserted in the furnace body and an upper pressure head is fixed on the lower end face of the hydraulic cylinder piston. A parallelism regulating table is positioned in the furnace body and is fixed on the upper end face of a bearing pillar and a lower pressure head is positioned on the upper surface of the parallelism regulating table. The surface of the upper pressure head corresponds to the surface of the lower pressure head. Three electric stove wires are uniformly distributed on the periphery of the inner wall of the furnace body and both ends of each electric stove wire are respectively welded with one corresponding group of electrodes outside the furnace body. Three groups of electrodes are uniformly distributed on the furnace body. In the leveling process, nitrogen protective gas is adopted and each parameter is monitored and regulated in real time, so that the leveling qualified rate is improved to 95 percent; and moreover, the disc-shaped panel leveling device is provided with a characteristic which comprises a simple structure and is convenient to operate.

Description

technical field [0001] The invention relates to the fields of hydraulic pressure and boilers, and specifically solves the problem that the warpage of the aircraft brake disc skeleton exceeds the standard. Background technique [0002] When the aircraft brakes, the hydraulic system pressurizes the brake piston and holds the thermal storage assembly tightly. The friction between the brake discs in the thermal storage assembly generates a lot of heat, and the temperature rises. Because the frame material is alloy steel, it is often in this Under high pressure and high temperature, the skeleton is prone to warping deformation, so that its warping degree exceeds the standard. [0003] At present, the civil aviation maintenance industry requires that the warpage of the brake disc frame is no more than 0.35 ~ 0.45mm (the warpage requirements of different part numbers are different). For the brake disc frame with excessive warpage, the airline may directly scrap it and replace it wi...
