A deep hole inner wall repair spray gun and repair method

Abstract

The invention discloses a deep hole inner wall repairing spray gun and a repairing method, including an extension rod, a support mechanism, an imaging device, a height sensor, an arc voltage stabilization controller, a nozzle and a connecting rod, etc., and the supporting mechanism is designed to support the extension rod , to solve the problem of disturbance deformation and jitter amplification of the extension rod. When the extension rod and the connecting rod are connected through an arc voltage stabilization controller, the height of the connecting rod is adjusted in real time to adjust the arc voltage, improve the repair quality, reduce jitter, and integrate into the industry The sight glass and height sensor solve the problem that the inner wall of the deep hole is not easy to teach, and realize partial repair of defects. The deep hole inner wall repair spray gun and repair method provided by the present invention solve the problems of poor repair quality and precision of the deep hole inner wall and the inability to repair the inner wall of small holes, realize high-precision and high-quality partial repair of the inner wall of the deep hole, and reduce the cost of repairing the inner wall of the deep hole. The cost and the risk of deformation due to excessive heat input during the repair process; improve the quality and efficiency of repair.

Description

technical field [0001] The invention belongs to the technical field of engineering machinery, and in particular relates to a deep hole inner wall repairing spray gun and a repairing method. Background technique [0002] As the key component of energy conversion and power transmission of construction machinery, hydraulic cylinder has frequent movements, high working frequency and fast response. Its performance determines the control stability and accuracy of the whole machine product, so the requirements for the system are particularly strict. The working environment of construction machinery is harsh, and the intrusion of hard particles, eccentric loads and the existence of metal wear debris on site can easily lead to strain on the inner wall of the cylinder, causing internal leakage of hydraulic oil and other problems, which seriously affect the construction quality and process. In order to promote the development of circular economy, scrapped oil tanks are usually recycled...
