Description

Technical Field

[0001] This utility model belongs to the field of surfacing technology, and relates to surfacing devices, particularly to roller sleeve surfacing devices. Background Technology

[0002] As an economical and rapid process for material surface modification, welding is increasingly widely used in the manufacturing and repair of parts in various industrial sectors. To maximize the effectiveness of the weld overlay, it is desirable to employ a welding method with minimal base material dilution, high deposition rate, and excellent weld overlay performance—that is, a high-quality, high-efficiency, and low-dilution welding technology.

[0003] For example, a welding device with publication number CN217193485U includes a welding torch, a first powder feeder and a second powder feeder. The first powder feeder and the second powder feeder are arranged at intervals from the welding torch. The first powder feeder or the second powder feeder can move simultaneously with the welding torch along the vertical direction or along the horizontal direction and approach or move away from the workpiece. The first powder feeder and the second powder feeder are respectively connected to the welding torch. The first powder feeder and the second powder feeder are respectively used to feed different welding materials to the welding torch.

[0004] The aforementioned welding device sprays powder onto the surface of the workpiece and then processes the surface of the workpiece with a welding gun to complete the welding. However, during the welding gun processing and powder spraying, there is a situation where powder is scattered on the edge of the chuck, causing waste and increasing the welding cost. Utility Model Content

[0005] This invention provides a roller sleeve overlay welding device that can collect powder scattered on the edge of the chuck, thereby reducing waste and lowering costs.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a roller sleeve welding device, including a chuck, a baffle is sleeved on the edge of the chuck, a plurality of mounting grooves are opened on the bottom surface of the baffle, a fan is fixedly connected in each mounting groove, and a collecting ring is detachably connected to the baffle below the fan. A groove communicating with the mounting groove is opened in the collecting ring. When the fan is turned on before spraying powder, the powder scattered on the edge of the chuck enters the groove through the fan.

[0007] A further preferred embodiment of this utility model is as follows: the baffle includes an inclined plate and a flat plate integrally formed with the inclined plate, the fan and the collecting ring are both disposed on the flat plate, and the diameter of the inclined plate gradually increases from the end closer to the flat plate to the end farther away from the flat plate.

[0008] A further preferred embodiment of this utility model is as follows: the collecting ring includes two arc-shaped plates, which are detachably connected. Each of the two arc-shaped plates has an opening communicating with the groove. When the arc-shaped plates are assembled on the flat plate, the opening is closed.

[0009] A further preferred technical solution of this utility model is as follows: each of the two arc-shaped plates has an integrally formed mounting plate on its opposite surface, and each mounting plate has a threaded hole. When assembling the arc-shaped plates, the mounting plates on the two arc-shaped plates abut against each other and bolts are provided in the threaded holes.

[0010] A further preferred technical solution of this utility model is as follows: the flat plate extends outward to form an extension plate, the extension plate is provided with a plurality of sliding grooves and through holes communicating with the sliding grooves, and a fixing plate is fixedly connected to each of the arc plates. The fixing plate is an L-shaped plate. When assembling the arc plate and the extension plate, the fixing plate enters the sliding groove through the through hole and is rotated to make the fixing plate abut against the top surface of the extension plate.

[0011] A further preferred embodiment of this utility model is as follows: a locking block is integrally formed on the fixing plate, and a slot is provided on the inner side wall of the slide groove to facilitate the locking block's insertion.

[0012] A further preferred embodiment of this utility model is that both the card block and the card slot are provided with arc-shaped surfaces.

[0013] A further preferred embodiment of this utility model is: an inclined surface is provided on the bottom surface of the groove, and the inclined surface slopes from the end away from the opening toward the opening.

[0014] A further preferred embodiment of this utility model is as follows: sealing gaskets are fixedly connected to the opposite surfaces of the two arc-shaped plates, and the sealing gaskets deform when the two arc-shaped plates are assembled.

[0015] Compared with the prior art, this utility model includes a chuck with a baffle plate fitted around its edge. Several mounting slots are formed on the bottom surface of the baffle plate, and a fan is fixedly connected to each mounting slot. A collection ring is detachably connected to the baffle plate, and a groove communicating with the mounting slot is formed in the collection ring. When the fan is turned on before spraying powder, the powder scattered on the edge of the chuck enters the groove through the fan. By setting the baffle plate, the powder can be effectively prevented from being sprayed outside the chuck, affecting collection and causing waste. The fan can absorb the powder scattered on the edge of the chuck into the groove for collection, thereby avoiding powder waste and effectively reducing the welding cost. Attached Figure Description

[0023] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0024] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0025] Figure 1 and Figure 2 As shown, the roller sleeve welding device includes a chuck 1, on which a baffle is fitted. The baffle can prevent powder from being sprayed outside the chuck 1 and causing waste, and performs preliminary collection of powder.

[0026] Figure 1 and Figure 2As shown, the baffle includes an inclined plate 2 and a flat plate 4 integrally formed with the inclined plate 2. The diameter of the inclined plate 2 gradually increases from the end near the flat plate 4 to the end away from the flat plate 4. This design can better block the drifting powder.

[0027] Figure 1 and Figure 2 As shown, several mounting slots 6 are provided on the bottom surface of the plate 4. A fan 5 is fixedly connected in each mounting slot 6. By setting the fan 5, the powder on the chuck 1 can be absorbed and collected, thereby further avoiding the waste of powder. At the same time, the baffle is sleeved on the bottom of the chuck 1. At this time, the fan 5 is installed on the plate 4 at the bottom end of the inclined plate 2. Therefore, there is a certain distance between the fan 5 and the surface of the chuck 1, which can effectively prevent the fan 5 from sucking away the powder on the parts and affecting the welding. This design effectively ensures that the fan 5 can only collect the powder scattered in the baffle and at the edge of the chuck 1.

[0028] Figure 2 and Figure 3 As shown, the plate 4 is detachably connected to a collection ring located below the fan 5. The collection ring has a groove 12 that communicates with the mounting slot 6. Therefore, after the fan 5 pushes the powder into the mounting slot 6, the powder falls into the groove 12 through the mounting slot 6 for collection. This design allows the powder to be stored and collected easily.

[0029] Figures 2-4 As shown, the collecting ring includes two arc-shaped plates 3, which are detachably connected. Each arc-shaped plate 3 has an opening 14 that communicates with the groove 12. When the arc-shaped plates 3 are assembled on the flat plate 4, the opening 14 is closed by the outer wall of the chuck 1. Therefore, when there is a lot of powder in the groove 12, the opening 14 can be opened by disassembling the arc-shaped plates 3, and the powder can be poured out through the opening 14, which facilitates collection again.

[0030] Figures 2-4 As shown, a slope 13 is provided on the bottom surface of the groove 12. The slope 13 is inclined from the end away from the opening 14 toward the opening 14. By setting the slope 13, the powder falling into the groove 12 can be gathered at the opening 14, which makes it easier to remove the powder later.

[0031] Figures 2-4 As shown, mounting plates 7 are integrally formed on the opposite surfaces of the two arc-shaped plates 3. Each mounting plate 7 has a threaded hole 15. When assembling the arc-shaped plates 3, the mounting plates 7 on the two arc-shaped plates 3 abut against each other and bolts 8 are provided in the threaded holes 15.

[0032] Figures 2-4 As shown, the installation plate 7 and bolts 8 facilitate the disassembly and installation of the two arc-shaped plates 3.

[0033] Figures 2-5As shown, the flat plate 4 extends outward to form an extension plate 9. The extension plate 9 has several grooves 11 and through holes 18 communicating with the grooves 11. Each arc plate 3 is fixedly connected to a fixing plate 10. The fixing plate 10 is an L-shaped plate. When the arc plate 3 and the extension plate 9 are assembled, the fixing plate 10 enters the groove through the through hole 18 and rotates to make the fixing plate 10 abut against the top surface of the extension plate 9.

[0034] Figures 2-5 As shown, when assembling the arc plate 3, the fixing plate 10 on one of the arc plates 3 is aligned with the through hole 18 and inserted until the top surface of the arc plate 3 abuts against the bottom surface of the flat plate 4. The arc plate 3 is then rotated further to allow the fixing block to slide into the slide groove 11. At the same time, the fixing block abuts against the top surface of the flat plate 4, thereby limiting the axial movement range of the arc plate 3 and preventing the arc plate 3 from separating from the flat plate 4 and falling off when the chuck 1 is used.

[0035] Figures 2-5 As shown, repeat the above operation to install another arc plate 3 on the flat plate 4. At this time, the mounting plates 7 on the two arc plates 3 form an abutment and the threaded holes 15 are aligned. Finally, screw the bolts 8 into the corresponding threaded holes 15 to complete the assembly and installation of the collecting ring.

[0036] Figures 2-5 As shown, a locking block 16 is integrally formed on the fixing plate 10, and a slot 17 is provided on the inner side wall of the slide groove 11 to facilitate the locking block 16 to be inserted. Therefore, when the arc plate 3 is rotated so that the fixing block and the top surface of the plate 4 come into contact, the locking block 16 is also inserted into the slot 17, thereby fixing the fixing block and preventing the collecting ring from rotating when the chuck 1 is in use.

[0037] Figures 2-5 As shown, both the card block 16 and the card slot 17 have arc-shaped surfaces, which makes it easier for the card block 16 to be inserted into the card slot 17, thus improving the ease of operation.

[0038] Figures 2-5 As shown, sealing gaskets are fixedly connected to the opposite surfaces of the two arc-shaped plates 3. When the two arc-shaped plates 3 are assembled, the sealing gaskets deform. This design improves the sealing between the two arc-shaped plates 3 and prevents powder from falling through the gap between the two arc-shaped plates 3.

[0039] The roller sleeve welding device provided by this utility model has been described above. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand this utility model and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from its principle, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
