[0050] It is worth noting that the multi-beam technology formed by the laser cladding nozzle 3 described above is a publicly known technology, and more detailed information can be referred to the disclosed patents cited in the background art, which will not be described in more detail herein.

[0051] In combination Figure 1 , Figure 5 and Figure 6 As further shown, the moving platform 5 comprises two symmetrically arranged Y-axis assemblies 8, a support slide 10 sliding on the Y-axis assemblies 8 respectively, an X-axis assembly 9 connected to the support slide 10 and symmetrically arranged, and a center ring 11 sliding on the X-axis assembly 9, and the nozzle assembly 2 is fixedly installed on the center ring 11 through the first connecting rod 4, and the Y-axis assemblies 8 are used to drive the support slide 10 to move along the Y-axis direction, and the X-axis assembly 9 is used to drive the center ring 11 to move along the X-axis direction.

Moreover, the nozzle assembly 2 adjusted in the Y-axis direction can also make the cladding layer be distributed in a biased manner, thereby meeting the repair requirements of special working conditions and reducing processing defects.

[0054] As shown in Figure 11 , when the repair area is irregular and the cross-sectional shape of the cladding morphology distribution is asymmetric, it is necessary to adjust the positional relationship between the nozzle assembly 2 and the light spot, so that the cladding layer also presents a biased distribution, thereby meeting the repair requirements of special working conditions.

[0055] As a further improvement, in combination with Figure 4 , the X-axis assembly 9 includes a second motor 91 corresponding to the two support slides 10, a second synchronous wheel 92 connected to the output end of the second motor 91, a second synchronous belt 93 meshed with the two second synchronous wheels 92, and two curved slide rods 94 installed between the two support slides 10. The center ring 11 is slidably arranged on the outer wall of the two curved slide rods 94, and part of the belt body of the second synchronous belt 93 is connected to the center ring 11 through a clamping member.

[0056] The second motor 91 is used to provide kinetic energy to drive the second synchronous wheel 92 to rotate, and then the second synchronous wheel 92 drives the center ring 11 to move back and forth through the second synchronous belt 93, so that the nozzle assembly 2 can be adjusted in the X-axis direction, ensuring that the nozzle assembly 2 can be accurately aligned with the light spot formed by multiple light beams, and ensuring that the powder can be accurately delivered to the light spot action area, thereby improving the utilization rate of the powder. Moreover, the nozzle assembly 2 adjusted in the X-axis direction can also make the cladding layer be distributed in a biased manner, thereby meeting the repair requirements of special working conditions.

[0057] As shown in Figure 12 , when the repair area is irregular and the cross-sectional shape of the cladding morphology is left-biased or right-biased, it is necessary to adjust the positional relationship between the nozzle assembly 2 and the light spot, so that the nozzle corresponds to the biased position of the cladding layer, thereby meeting the repair requirements of special working conditions.

[0058] It is worth noting that the clamping piece described herein is a synchronous belt pressing plate, which clamps and fixes a part of the synchronous belt on the support slide 10 or the center ring 11, so as to ensure that the synchronous belt can be fixedly connected with the support slide 10 or the center ring 11, and ensure that the synchronous belt keeps synchronous movement with the support slide 10 or the center ring 11 in the transmission process, thereby facilitating the X-axis direction or Y-axis direction movement of the nozzle assembly 2.

[0059] As shown in Figure 3 and Figure 4 As further shown, the support slide 10 includes a sliding block 101 and a support plate 102 connected to the upper and lower end faces of the sliding block 101, the second motor 91 is fixedly installed on the support plate 102, the straight sliding rod 85 is movably penetrated through the sliding block 101, the straight sliding rod 85 is used to support the sliding block 101, and the first synchronous belt 84 is connected to the sliding block 101, the first synchronous belt 84 clamps and fixes a part of the synchronous belt on the sliding block 101 through the synchronous belt pressing plate, so as to ensure that the synchronous belt can be fixedly connected with the sliding block 101, realize the movement of the sliding block 101 following the first synchronous belt 84 when the first synchronous belt 84 is driven, and complete the Y-axis direction movement of the nozzle assembly 2.

[0060] As further shown, the surface of the center ring 11 is penetrated through with a plurality of side holes 12, two side holes 12 on the same side are taken as a group in the plurality of side holes 12, and two curved sliding rods 94 are correspondingly arranged in the two groups of side holes 12, wherein the plurality of side holes 12 are in an arc shape to adapt to the movement on the curved sliding rod 94, thereby facilitating the X-axis direction movement of the nozzle assembly 2.

[0061] As shown in Figure 9 It is worth noting that the curved sliding rod 94 is designed to be curved, which mainly ensures that the curved sliding rod 94 will not block the multi-beam generated by the laser beam assembly 1, so as to ensure that the multi-beam can be normally projected on the substrate or the cladding layer. More attention is paid to the fact that the adjustment of the center ring 11 driving the nozzle assembly 2 in the X-axis or Y-axis direction is always in the inside area of the light spot, so that the center ring 11 will not cause the blocking phenomenon of the multi-beam projection in the case of short adjustment distance.

[0062] As shown in Figure 9 As further shown, the first connecting rod 4 includes a plurality of short connecting rods 41 connected to the inner side wall of the center ring 11 and a first sleeve ring 42 commonly connected to one end of the plurality of short connecting rods 41, the nozzle assembly 2 is arranged on the inner side of the first sleeve ring 42, and the plurality of short connecting rods 41 are arranged in a staggered manner with the plurality of reflection light path through holes 14 on the laser beam assembly 1, wherein the short connecting rod 41 is provided with at least three, and the stability of the first sleeve ring 42 can be ensured through the three short connecting rods 41, thereby ensuring the stability of the nozzle assembly 2 in use.

It should be noted that the connection mode of the nozzle assembly 2 and the first ring 42 also adopts the same fixing structure.

[0064] The working principle and use process of the utility model: the position relationship of the light spot and the nozzle assembly 2 is observed in real time through the CCD camera 7, and the first motor 82 or the second motor 91 is controlled to start according to the position relationship data, so that the Y-axis direction movement of the nozzle assembly 2 can be realized through the cooperation of the first synchronous wheel 83, the first synchronous belt 84 and the supporting sliding seat 10 when the first motor 82 works; and the X-axis direction movement of the nozzle assembly 2 can be realized through the cooperation of the second synchronous wheel 92, the second synchronous belt 93 and the center ring 11 when the second motor 91 works, so that the position relationship of the nozzle assembly 2 and the light spot can be adjusted in real time, the coaxial relationship between the light spot and the nozzle position is always maintained when scanning in any direction, the powder utilization rate and the forming precision of complex parts are improved; and in some special application scenarios, the X-axis direction or Y-axis direction movement adjustment of the nozzle assembly 2 can dynamically make the nozzle assembly 2 and the light spot realize a certain offset, form a special appearance cladding layer, and expand special scene green repair work to meet the repair requirements of special working conditions.

[0067] Compared with the traditional technology with nozzle manual adjustment function, the advantages of the scheme are as follows:
