Embodiment 1
[0030] Such as figure 1 As shown, the device of the present invention includes a protective disc 11, a servo motor 13, a protective glass cleaning device 10, a support 15, a protective cover 9, and a control system.
[0031] figure 2 , image 3 It is a schematic diagram of the protective structure, and the protective plate 11 is composed of a plate body 18, a protective glass 17, a positioning plate 14, and a protective glass pressing device connected in sequence. Four pieces of protective glass 17 are symmetrically fixed on the reserved holes on the disc body 18 through the pressing device (pressing nut 16). When the protective glass is damaged or the pollution is very serious, the pressing nut 16 is removed and a new protective glass is replaced. Laser processing again.
[0032] The protective disc 11 is connected with the positioning disc 14 at the end of the servo motor 13 installed on the bracket 15 through the coupling screw 8 .
[0033] Both sides of the protective...
Embodiment 2
[0042] Basically the same as Example 1, the difference is that, as Figure 4 , Figure 5 Shown, protective glass pressing device is made up of pressing screw 19 and pressing plate 20. The ring-shaped protective glass 17 is fixed on the periphery of the disc body 18 through the compression screw 19 and the pressing plate 20 .
[0043] When the protective glass is damaged or polluted very seriously, remove the compression screw 19 and the pressing plate 20, replace a new protective glass plate, and carry out laser shock again.
[0044] In this embodiment, the protective glass sheet is easy to replace, the production efficiency is high, the protective glass is large, and the price is high, which is convenient for multi-point continuous work, and is suitable for the application of laser shock composite life extension engineering with long working hours.

Abstract
The invention relates to the technical field of laser processing and lasers, in particular to a protection method and a protection device for a lens of a laser compounded life-prolonging laser for a heat-resistant part. A protection disk which is orderly connected with a servomotor, a frame, a control system, a protective cover, and a protection glass cleaning device is arranged between the lens of the laser and a test specimen to protect the lens; during a pulse interval of laser shock, the servomotor drives the protection disk to rotate with certain angle; during the continuous laser action of laser cladding and quenching, the servomotor drives the protection disk to continuously rotate, so a polluted position of the protection disk is away from a laser working position; the position of the protection disk which is quickly cleaned by the protection glass cleaning device moves to the laser working position and prepares for continuous laser work; at the same time, the protection glass cleaning device cleans and dries the polluted position of the protection disk. The protection device has the advantages that the protection device has a simple structure and low cost, simplifies the cleaning process of the lens, has no scratches on protection glass, and is convenient to realize multi-point continuous shock and long laser cladding and quenching.
Description
technical field [0001] The invention relates to the field of laser special processing and laser technology, in particular to a method and a device for protecting a heat-resistant component laser composite life extension laser lens. Background technique [0002] Since the advent of lasers in the 1960s, laser technology has been rapidly developed and applied. Laser application technologies such as laser shock wave technology, laser cutting technology, laser welding technology, laser marking technology, laser cladding technology, and laser detection technology are currently widely used. Used in mechanical engineering, aerospace, microelectronics, military and other industries. [0003] Grate machine-rotary kiln-circular cooler is one of the important production processes for iron and steel smelting furnace materials. Its working temperature ranges from normal temperature to 1200°C. The reciprocating operation in the medium cycle requires extremely high thermal fatigue performa...
