Example Embodiment

[0025] Example 1

[0026] A motor I 6 is installed on the base 4, and the motor I is connected to the platform 3 through the eccentric rocker arm 9. The platform 3 is provided with a motor II 7 and a counterweight 5, and the motor II is connected to the bottle body 2 through a chain. A fixing frame for fixing the bottle body 2; the fixing frame is composed of a chuck 1 and a tail top 8.

[0027] Taking a small-caliber gas cylinder as an example, the rust removal method of the present invention includes the following steps:

[0028] Fill the bottle to be processed with high-hardness abrasives and liquids, and use the tail top and chuck to fix the bottle; when the motor II works, the bottle is driven by the chain to rotate; the abrasive in the bottle rotates by gravity and the bottle When the motor I rotates, the eccentric rocker arm drives the platform to swing up and down, which drives the bottle to swing, and the abrasive in the bottle also produces relative movement. At this tim...

Abstract

The invention relates to a finishing rust removal device and method for liners. The device and the method are used for removing rust on the inner surfaces of bottles of aerospace gas path systems. According to the structure of the device, a motor I is mounted on a base and connected with a platform through a transmission unit I, a motor II is mounted on the platform and connected with a bottle body through a transmission unit II, and a fixing frame for fixing the bottle body is arranged above the platform. According to the device and the method, a finishing rust removal technology is used, and rust removal is achieved through grinding of grinding materials and the inner surface of the bottle body, so that corrosion substances in the cavity of the inner surface of the bottle body are effectively removed, problems of hydrogen embrittlement caused by acid pickling and uncompleted cleaning of local corrosion of sand blasting are solved, and the high generalization performance is provided for the inner surface rust removal of bottle bodies.

Description

technical field [0001] The invention relates to a device and a method for removing rust on the inner surface of equipment, in particular to an inner tank light decoration rust removal device and a rust removal method for removing rust on the inner surface of a bottle of an aerospace gas path system. Background technique [0002] At present, the rust removal of the inner surface of the gas cylinder in the aerospace gas system has always been a technical problem in the field, especially the rust removal of the inner surface of the irregularly shaped bottle is not easy to operate. The rust removal methods in the prior art are mainly sandblasting and pickling, but the above methods have their limitations. Sandblasting the inner tank of the bottle is prone to blind spots, resulting in the problem that the rust cannot be removed. Pickling is forbidden for strong steel. Restricted technology, prohibited in aviation and aerospace enterprises. [0003] Rolling is the process of putt...
