Deep hole laser cladding head

Abstract

The invention provides a deep hole laser cladding head. The deep hole laser cladding head comprises a base, a cladding head middle section and a machining head section, wherein the base is provided with an optical fiber connector, a collimating lens and a focus lens; the machining head section is provided with a reflecting mirror and a protective glass; the cladding head middle section comprises a water pipe, a gas pipe, a powder pipe, a line pipe, multiple fixing frameworks, an inner thin-walled sleeve and an outer thin-walled sleeve. The fixing frameworks are in a circular ring shape. A main body of each fixing framework is provided with a first water hole, a first gas hole, a first powder hole and a first line hole which correspond to the water pipe, the gas pipe, the powder pipe and the line pipe correspondingly. The water pipe, the gas pipe, the powder pipe and the line pipe penetrate through the corresponding first water holes, the corresponding gas holes, the corresponding first powder holes and the corresponding first line holes in the fixing frameworks in sequence. The inner thin-walled sleeve penetrates through inner holes of the fixing frameworks in sequence. The outer thin-walled sleeve is connected to the outer surfaces of the fixing frameworks in a sleeving mode. The deep hole laser cladding head can be suitable for cladding of inner holes, with the diameter being 100-200mm and the diameter ratio greater than 40, of pipe fittings.

Description

technical field [0001] The invention relates to the field of laser cladding heads, in particular to a laser cladding head suitable for deep holes. Background technique [0002] In the existing relevant inner hole cladding head, due to the limitation of the structure, it is not applicable to those with a diameter of 100 to 200 mm and a multiple-to-diameter ratio of 30 to 50. For example: Chinese patent application number 201020611034.1 discloses an adjustable length inner hole cladding head, but it can only be applied to holes with a diameter greater than 200 mm and a length of 300 to 1000 mm (the ratio of diameter to diameter is 1.5 to 5). Bore. [0003] For holes with a diameter in the range of 100 to 200 mm and a ratio of diameter to diameter in the range of 40 to 50, the length ranges from 4 meters to 10 meters. For such an inner hole, if the laser cladding head can extend from both ends of the inner hole, the length of the laser cladding head suitable for the above spe...
