[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] It should be noted that the terms “vertical”, “horizontal”, “up”, “down”, “left”, “right” and similar expressions used in this document are only for illustrative purposes and do not represent the only implementation method.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field of the present invention; the terms used in the specification of the present invention are only for the purpose of describing specific implementation methods and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0027] like Figure 1 and Figure 2 As shown, a laser cladding welding machine tool provided by the utility model includes a base 1, an adjusting structure 2 is provided above the base 1, an outer shell 13 is provided on the outside of the base 1 and is placed on the base 1 and outside the adjusting structure 2, the inner side of the outer shell 13 is connected to a cladding laser head 14 corresponding to a welding seat 12, the other side of the welding seat 12 is provided with a powder feeding hole 15 connected to the inner side of the outer shell 13, the welding seat 12 is provided with a groove 16 corresponding to the powder feeding hole 15, the adjusting structure 2 includes an adjusting rod 21 which is placed inside the base 1 and is symmetrically distributed, the adjusting rod 21 is connected to an adjusting gear 22, the adjusting gear 22 is connected to a welding workpiece 11 through a transmission gear 23, the other end of the welding workpiece 11 is connected to a welding seat 12 placed on the base 1, the welding seat 12 is provided with a supporting groove 17 corresponding to the cladding laser head 14 and the powder feeding hole 15, and the supporting groove 17 is connected to the groove 16.

[0028] In this embodiment, an adjustment structure 2 is provided inside the base 1, and the adjustment gear 22 on the adjustment rod 21 is rotated to intermittently drive the welding workpiece 11 to rotate, so that it can be more stably and evenly coated and welded on the welding seat 12. The metal powder contacts the welding workpiece 12 through the welding seat 12, ensuring a more uniform contact surface.

[0029] like Figure 3 and Figure 4 As shown, an adjustment groove 24 corresponding to the adjustment rod 21 on one side is provided on one side of the base 1, and a threaded rod 18 penetrating the connecting piece 211 is connected to the lower side of the adjustment rod 21 through a connecting piece 211, and the end of the threaded rod 18 close to the adjustment groove 24 is inserted into the outer shell 13, and a buffer groove 212 corresponding to the adjustment gear 22 and the transmission gear 23 is provided on the side of the adjustment rod 21 close to the adjustment gear 22, and a limiting rod 214 fixedly connected to the adjustment gear 22 and the transmission gear 23 is connected to the inside of the buffer groove 212 through a spring 213, and a plurality of evenly distributed support rods 25 are connected to the side of the transmission gear 23 away from the adjustment rod 21, and a blocking member 26 fixedly connected to the adjustment rod 21 is provided at the end of the adjustment gear 22 away from the transmission gear 23, and a part of the gear teeth corresponding to the transmission gear 23 are arranged on the adjustment gear 22.

[0030] In this embodiment, when the adjusting gear 22 is driven to rotate by an external force such as a driving motor or other existing technologies, the gear teeth on the adjusting gear 22 drive the transmission gear 23 to rotate. When the gear teeth leave the transmission gear 23 and contact the blocking member 26, the adjusting gear 22 will rise and lift the transmission gear 23. The transmission gear 23 lifts the welding workpiece 11 with the help of the support rod 25, so that the powder feeding hole 15 sends the metal powder to the groove 16 on the welding seat 12. It should be noted that the limiting rod 214 connected to the adjusting gear 22 and the transmission gear 23 are both T-shaped, and the end with a larger diameter is placed in the buffer groove 212 on the adjusting rod 21. The width of the opening of the buffer groove 212 is smaller than the width in the groove. Therefore, the movable connection between the gear and the adjusting rod 21 can be achieved with the help of the limiting rod 214. Because this technology is a relatively mature means under the existing technology and can be thought of by people in this field, it is not described in detail herein.

[0031] When in use, ensure that the laser cladding welding machine is in normal working condition, check whether all components are intact, and prepare the required metal powder and welding workpiece; the adjustment structure 2 is placed inside the base 1, and the adjustment gear 22 on the adjustment rod 21 is connected to the welding workpiece 11 through the transmission gear 23; the metal powder is sent to the groove 16 on the welding seat 12 through the powder feeding hole 15 to ensure that the metal powder evenly covers the welding area; the adjustment gear 22 is driven to rotate by an external force such as a driving motor and other existing technologies, and the gear teeth on the adjustment gear 22 drive the transmission gear 23 to rotate; when the gear teeth leave the transmission gear 23 and contact the blocking member 26, the adjustment gear 22 will rise and lift the transmission gear 23, and the transmission gear 23 will lift the welding workpiece 11 with the help of the support rod 25, so that the welding workpiece 11 is evenly coated and stably welded on the welding seat 12; after the welding is completed, stop the machine tool, check the welding quality, and ensure that the expected covering repair, coating and modification effects are achieved; clean the welding area, perform necessary maintenance on the machine tool, and ensure the long-term stable operation of the equipment.

[0032] Although the present invention has been disclosed as above in terms of preferred embodiments, it is not intended to limit the present invention. Anyone familiar with the technology may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the claims.
