Description

Technical Field

[0001] This invention relates to the technical field of grinding roller processing, specifically to a cladding device for processing a wear-resistant layer on the surface of a grinding roller sleeve. Background Technology

[0002] With the continuous development of industrial technology, the demand for wear-resistant coatings on the surface of grinding roller sleeves is increasing. As a key piece of equipment for realizing this process, the performance of the cladding device directly affects the processing effect and product quality. However, existing cladding devices have some obvious defects in their design and use, which limit their effectiveness in practical applications.

[0003] Existing cladding devices typically include a worktable, robotic arm, laser cladding head, support, and rotating disk. These components work together to apply a wear-resistant layer to the surface of the grinding roller sleeve. However, in practical use, operators have found the following main drawbacks in existing technologies:

[0004] For example, the position and width of the positioning block cannot be adjusted: in the prior art, the positioning block is usually fixedly installed, and its position cannot be adjusted once it is determined. Since different workpieces may have different shapes and sizes, the fixed positioning block is difficult to adapt to the processing requirements of various workpieces, which to some extent limits the application range of the cladding device; therefore, we propose a cladding device for processing the wear-resistant layer on the surface of the grinding roller sleeve. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a cladding device for processing a wear-resistant layer on the surface of a grinding roller sleeve.

[0006] This invention adopts the following technical solution: a cladding device for processing a wear-resistant layer on the surface of a grinding roller sleeve, comprising a worktable, a laser cladding head fixedly mounted on the upper end of the worktable via a robotic arm, a bracket fixedly mounted on the upper end of the worktable, a first rotating disk rotatably mounted on the front end of the bracket, a second rotating disk rotatably mounted on the front end of the first rotating disk, a plurality of second limiting grooves arranged in a circular array on the front end of the second rotating disk, a second limiting slider slidably mounted within the second limiting groove, a plurality of first limiting grooves on the front end of the first rotating disk, a limiting rod fixedly mounted in the middle of the second limiting slider, the limiting rod slidably connected to the first limiting groove, two symmetrically arranged positioning blocks at the front end of each limiting rod, a threaded plate fixedly mounted in the middle of the two positioning blocks and inserted into the limiting rod, a threaded rod rotatably mounted within the limiting rod and threadedly connected to the threaded plate, and a drive motor fixedly mounted on the upper end of the worktable, the drive motor being rotatably connected to the first rotating disk via a transmission belt.

[0007] As a further description of the above technical solution: a rotating shaft is fixedly installed in the middle of the first rotating disk, and the rotating shaft is rotatably installed in the bracket; a rotating rod that is rotatably connected to the rotating shaft is fixedly installed in the middle of the second rotating disk.

[0008] As a further description of the above technical solution: the rotating rod and the rotating shaft are respectively provided with a first positioning tooth hole and a second positioning tooth hole, and positioning tooth blocks are inserted and installed in the first positioning tooth hole and the second positioning tooth hole.

[0009] As a further description of the above technical solution: a cavity is provided at the rear end of the rotating shaft, a handle is provided in the cavity, the handle is fixedly connected to the positioning tooth block through a connecting rod, and a first spring is fixedly installed between the handle and the cavity.

[0010] As a further description of the above technical solution: a driven wheel is fixedly installed at the rear end of the threaded rod, and a tensioning wheel and an adjusting gear are provided on both sides of each driven wheel. The outer peripheries of adjacent driven wheels, tensioning wheels, and adjusting gears are rotatably connected to each other through a transmission belt. A toothed ring is rotatably installed at the rear end of the first rotating disk, and the outer periphery of each adjusting gear is meshed with the inner wall of the toothed ring.

[0011] As a further description of the above technical solution: a first connecting seat is fixedly installed at the rear end of the driven wheel, and a second connecting seat is fixedly installed at the rear end of the tensioning wheel.

[0012] As a further description of the above technical solution: a second spring and a telescopic sleeve that are inserted into each other are fixedly installed between the first connecting seat and the second connecting seat, and the second spring is located inside the telescopic sleeve.

[0013] This invention provides an improved cladding device for processing a wear-resistant layer on the surface of a grinding roller sleeve, which has the following improvements and advantages compared with the prior art:

[0014] Firstly, through the sliding connection between the second limiting slider and the second limiting groove, and between the first limiting groove and the limiting rod, the relatively rotating first and second rotating disks can drive each positioning block to retract inward or expand outward, so that it fits against the inner ring of the grinding roller. Furthermore, through the threaded connection between the threaded rod and the threaded plate, the distance between the positioning blocks on the front and rear sides can be adjusted, so that the two positioning blocks fit against the front and rear sides of the inner ring of the grinding roller respectively, thereby improving the positioning effect of the positioning blocks on the grinding roller.

[0015] Secondly, by inserting the positioning tooth block into the first positioning tooth hole and the second positioning tooth hole, the connection between the first rotating disk and the second rotating disk can be positioned, so that the drive motor can drive each positioning block to rotate through its output shaft and transmission belt, thereby driving the grinding roller to rotate, which facilitates the laser cladding head to perform cladding treatment on various parts of the grinding roller surface.

[0016] Thirdly, a second spring is installed between the driven wheel and the tensioning wheel, so that the transmission belt is always sleeved on the driven wheel, the tensioning wheel, and the adjusting gear. Through the transmission belt, the driven wheel, the tensioning wheel, and the adjusting gear are rotated and connected to each other. Through the meshing connection between the adjusting gear and the gear ring, the rotating gear ring can drive each threaded rod to rotate, thereby simultaneously adjusting the distance between the front and rear sides of each set of positioning blocks.

[0030] To make the technical means, creative features, objectives, and effects of this invention readily understandable, the invention is further described below with reference to specific illustrations. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0031] Please see Figure 1 - Figure 7 This invention provides a technical solution: a cladding device for processing a wear-resistant layer on the surface of a grinding roller sleeve, comprising a worktable 1, a laser cladding head 12 fixedly mounted on the upper end of the worktable 1 via a robotic arm 11, a support 2 fixedly mounted on the upper end of the worktable 1, a first rotating disk 22 rotatably mounted on the front end of the support 2, a second rotating disk 23 rotatably mounted on the front end of the first rotating disk 22, a plurality of second limiting grooves 25 arranged in a circular array on the front end of the second rotating disk 23, and second limiting sliders 27 slidably mounted in the second limiting grooves 25. Multiple first limiting slide grooves 24 are provided. A limiting slide rod 26 is fixedly installed in the middle of the second limiting slide block 27. The limiting slide rod 26 is slidably connected to the first limiting slide groove 24. Each limiting slide rod 26 has two symmetrically arranged positioning blocks 4 at its front end. A threaded plate 41 that is inserted and connected to the limiting slide rod 26 is fixedly installed in the middle of the two positioning blocks 4. A threaded rod 42 that is threadedly connected to the threaded plate 41 is rotatably installed inside the limiting slide rod 26. A drive motor 28 is fixedly installed on the upper end of the worktable 1. The drive motor 28 is rotatably connected to the first rotating disk 22 through a transmission belt.

[0032] Working principle: When positioning the grinding roller, place the grinding roller in front of the second rotating disk 23, then position the second rotating disk 23 with one hand and rotate the first rotating disk 22 with the other hand. The second rotating disk 23 is connected to the second limiting slide groove 25 and the second limiting slider 27 through sliding connection. Under the restriction of the movement direction of each positioning block 4, the rotating first rotating disk 22 can drive each positioning block 4 to expand outward to contact the inner wall of the grinding roller through sliding connection between the first limiting slide groove 24 and the limiting slide rod 26.

[0033] Subsequently, within the limiting slide bar 26, the threaded rod 42 is rotated, and through the threaded connection between it and the threaded plates 41 on both sides, the positioning blocks 4 on the front and rear sides are driven to expand backward to fit against the front and rear sides of the inner ring of the grinding roller, thereby achieving the effect of positioning the grinding roller.

[0034] Start the drive motor 28, and through its output shaft and transmission belt, drive the first rotating disk 22 and the second rotating disk 23 to rotate, thereby driving the grinding roller to rotate. Then, through the robotic arm 11 and the laser cladding head 12, cladding treatment can be performed on various parts of the outer surface of the grinding roller.

[0035] In another embodiment of the present invention, a rotating shaft 21 is fixedly installed in the middle of the first rotating disk 22, and the rotating shaft 21 is rotatably installed in the bracket 2. A rotating rod 3, which is rotatably connected to the rotating shaft 21, is fixedly installed in the middle of the second rotating disk 23. A first positioning tooth hole 31 and a second positioning tooth hole 32 are respectively opened at the contact point between the rotating rod 3 and the rotating shaft 21. Positioning tooth blocks 35 are inserted into the first positioning tooth hole 31 and the second positioning tooth hole 32. A cavity 33 is opened at the rear end of the rotating shaft 21. A handle 34 is provided in the cavity 33. The handle 34 is fixedly connected to the positioning tooth block 35 through a connecting rod. A first spring 36 is fixedly installed between the handle 34 and the cavity 33.

[0036] Specifically, when it is necessary to rotate the first rotating disk 22 and the second rotating disk 23 relative to each other, the positioning tooth block 35 is pressed inward by the handle 34, so that the positioning tooth block 35 and the second positioning tooth hole 32 are separated from each other, thereby releasing the positioning effect between the rotating rod 3 and the rotating shaft 21, thus facilitating the relative rotation of the first rotating disk 22 and the second rotating disk 23.

[0037] When it is necessary to position the two, release the handle 34. Under the action of the first spring 36 restoring its deformation, the positioning tooth block 35 can be driven to return to its original position, so that the positioning tooth block 35 is re-inserted into the first positioning tooth hole 31 and the second positioning tooth hole 32, thereby achieving the effect of positioning the connection between the first rotating disk 22 and the second rotating disk 23.

[0038] When the drive motor 28 drives the first rotating disk 22 to rotate through its output shaft, transmission belt and rotating shaft 21, it can simultaneously drive the second rotating disk 23 to rotate with it, thereby achieving the effect of driving the grinding roller to rotate.

[0039] In another embodiment of the present invention, a driven wheel 43 is fixedly installed at the rear end of the threaded rod 42. Each driven wheel 43 is provided with a tensioning wheel 45 and an adjusting gear 44 on both sides. The outer peripheries of adjacent driven wheels 43, tensioning wheels 45, and adjusting gears 44 are rotatably connected to each other via a transmission belt. A toothed ring 40 is rotatably installed at the rear end of the first rotating disk 22. The outer periphery of each adjusting gear 44 is meshed with the inner wall of the toothed ring 40. A first connecting seat 46 is fixedly installed at the rear end of the driven wheel 43, and a second connecting seat 47 is fixedly installed at the rear end of the tensioning wheel 45. A second spring 49 and a telescopic sleeve 48 that are inserted into each other are fixedly installed between the first connecting seat 46 and the second connecting seat 47, and the second spring 49 is located inside the telescopic sleeve 48.

[0040] Specifically, when the first rotating disk 22 and the second rotating disk 23 rotate relative to each other, causing each positioning block 4 to retract inward or expand outward, the driven wheel 43 can be driven to move with the positioning block 4, and through the telescopic sleeve 48, the tension wheel 45 can be driven to move with the driven wheel 43. At this time, under the action of the second spring 49, the tension wheel 45 can support the transmission belt, so that the transmission belt is always sleeved around the adjusting gear 44, the tension wheel 45 and the driven wheel 43.

[0041] When it is necessary to adjust the distance between the front and rear positioning blocks 4 by rotating the threaded rod 42, the gear ring 40 can be rotated at the rear end of the first rotating disk 22. Through its meshing connection with the adjusting gear 44, the adjusting gear 44 can be driven to rotate. Then, through the transmission belt and tensioning wheel 45, the driven wheel 43 and the threaded rod 42 can be driven to rotate, so as to achieve the effect of driving the front and rear positioning blocks 4 to move in opposite directions or in opposite directions.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
