Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding device technology, and in particular to a grinding device for the weld seam of a coal mining machine frame. Background Technology
[0002] The coal mining machine frame refers to the frame structure that supports and installs the coal mining machine. During the frame installation process, various parts of the frame need to be welded. Welds will be produced during welding. These welds need to be ground smooth by a grinding device to avoid affecting the appearance and use.
[0003] In practical applications, existing grinding devices have relatively complete structures and functions, which can meet basic usage requirements, but the following problems still exist: In actual use, handheld grinders are usually used for grinding. However, the operating lever of a handheld grinder has a fixed length and cannot be adjusted according to the actual operating habits of the grinder. Furthermore, during the grinding process, the grinding dust can splash upwards and get into the grinder's eyes, thus affecting the grinding process.
[0004] Therefore, this utility model provides a grinding device for the weld seam of a coal mining machine frame. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a grinding device for the weld seams of a coal mining machine frame.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a coal mining machine frame weld grinding device, comprising a charging base, an operation adjustment structure provided on one side of the charging base, the operation adjustment structure comprising an operation cylinder, a hollow screw threadedly connected to the inner surface of the operation cylinder, an operation block fixedly connected to one end of the hollow screw, and a connecting plate rotatably connected to one side of the operation block; a protective grinding structure provided on one side of the connecting plate, the protective grinding structure comprising a rectangular block, one side of the rectangular block being fixedly connected to one side of the connecting plate, an installation groove provided on one side of the rectangular block, and a drive motor installed inside the installation groove.
[0007] In a preferred embodiment, a first connecting plate is fixedly connected to the bottom of the connecting plate, and a second connecting plate is fixedly connected to the bottom of the charging base. A sliding rod is fixedly connected to one side of the first connecting plate, and a fixed cylinder is fixedly connected to one side of the second connecting plate. The sliding rod is slidably disposed on one side of the fixed cylinder.
[0008] The technical effect of adopting the above-mentioned further solution is that the sliding rod can slide on the inner wall of the fixed cylinder, thereby limiting the connecting plate so that the connecting plate will not rotate during the rotation of the operating block, thus making the adjustment more stable.
[0009] In a preferred embodiment, an annular protrusion is fixedly connected to one side of the outer surface of the operating cylinder, and a rectangular protrusion is fixedly connected to the outer surface of the operating block.
[0010] The technical effects of adopting the above-mentioned further solutions are: the annular protrusion can increase the anti-slip properties when the operating cylinder is held, and the rectangular protrusion can increase the anti-slip properties when the operating block is operated.
[0011] In a preferred embodiment, a rotating rod is fixedly connected to the output end of the drive motor, a mounting plate is fixedly connected to the bottom end of the rotating rod, a grinding block is fixedly connected to the bottom of the mounting plate by bolts, a sliding round rod is fixedly connected to the top of the mounting plate, an annular groove is provided at the bottom of the rectangular block, the sliding round rod is slidably disposed on the inner wall of the annular groove, a threaded retainer is fixedly connected to the top of the rectangular block, a threaded retainer rod is threadedly connected to the inner wall of the threaded retainer rod, a connecting rod is fixedly connected to the top end of the threaded retainer rod, and a protective frame is fixedly connected to the top end of the connecting rod.
[0012] The technical effect of adopting the above-mentioned further solution is that: under the action of the rotating rod, the grinding block can be driven to rotate, thereby grinding the weld. At the same time, under the action of the sliding round rod, in conjunction with the annular groove, the rotating rod can be guided and connected during rotation. Under the action of the threaded clasp and threaded rod, the protective frame can be installed, thereby preventing debris from flying upwards and hitting the user's eyes during the grinding process.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: By setting up an operating adjustment structure, the hollow screw can be rotated under the action of the operating block, which in turn can move on the inner wall of the operating cylinder, thereby driving the connecting plate to move. The connecting plate can then drive the rectangular block and grinding block to move, allowing the hollow screw to adjust the operating length of the operating cylinder, making the grinding block suitable for the operator. By setting up a protective grinding structure, the rotating rod and grinding block can be rotated under the drive motor, thus grinding the coal mining machine frame. At the same time, the protective frame can be disassembled and assembled under the action of the threaded chuck and threaded rod, thus protecting the grinding debris from flying upwards and into the operator's eyes.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] like Figures 1-4As shown, this embodiment provides a technical solution: a coal mining machine frame weld grinding device, including a charging base 1. An operation adjustment structure 2 is provided on one side of the charging base 1. The operation adjustment structure 2 includes an operating cylinder 21. A hollow screw 22 is threadedly connected to the inner surface of the operating cylinder 21. An operating block 23 is fixedly connected to one end of the hollow screw 22. A connecting plate 24 is rotatably connected to one side of the operating block 23. A protective grinding structure 3 is provided on one side of the connecting plate 24. The protective grinding structure 3 includes a rectangular block 31. One side of the rectangular block 31 is fixedly connected to one side of the connecting plate 24. An installation groove 32 is opened on one side of the rectangular block 31. A drive motor 33 is installed inside the installation groove 32. By setting the operation adjustment structure 2, under the action of the operating block 23, the hollow screw 22 can be driven to grind the weld seam. The hollow screw 22 rotates, allowing it to move within the inner wall of the operating cylinder 21. This, in turn, moves the connecting plate 24, which in turn moves the rectangular block 31 and the grinding block 38. The hollow screw 22 can then adjust the operating length of the operating cylinder 21, allowing the grinding block 38 to be adapted for the operator's use. By setting up the protective grinding structure 3, the rotating rod 34 and the grinding block 38 can rotate under the drive of the drive motor 33, thus grinding the coal mining machine frame. Simultaneously, the protective frame 312 can be disassembled and assembled under the action of the threaded clamp 39 and the threaded clamp rod 310, protecting the grinding debris from flying upwards and into the operator's eyes.
[0018] Going a step further, such as Figure 2 As shown: A first connecting plate 25 is fixedly connected to the bottom of the connecting plate 24, and a second connecting plate 28 is fixedly connected to the bottom of the charging base 1. A sliding rod 26 is fixedly connected to one side of the first connecting plate 25, and a fixed cylinder 27 is fixedly connected to one side of the second connecting plate 28. The sliding rod 26 is slidably disposed on one side of the fixed cylinder 27. The sliding rod 26 can slide on the inner wall of the fixed cylinder 27, thereby limiting the connecting plate 24 so that the connecting plate 24 will not rotate during the rotation of the operating block 23, thus making the adjustment more stable.
[0019] The above solutions also have the problem that the operation of the control cylinder 21 and control block 23 is prone to slippage due to sweaty hands. Figure 2 As shown: In this solution, an annular protrusion 29 is fixedly connected to one side of the outer surface of the operating cylinder 21, and a rectangular protrusion 210 is fixedly connected to the outer surface of the operating block 23. The annular protrusion 29 can increase the anti-slip property when the operating cylinder 21 is held, and the rectangular protrusion 210 can increase the anti-slip property when the operating block 23 is operated.
[0020] The above solutions also have the problem that when using grinding block 38, the debris can easily splash upwards and into the operator's eyes. Figure 3 and Figure 4As shown, a rotating rod 34 is fixedly connected to the output end of the drive motor 33. A mounting plate 37 is fixedly connected to the bottom end of the rotating rod 34. A grinding block 38 is fixedly connected to the bottom of the mounting plate 37 by bolts. A sliding round rod 36 is fixedly connected to the top of the mounting plate 37. An annular groove 35 is provided at the bottom of the rectangular block 31. The sliding round rod 36 is slidably disposed on the inner wall of the annular groove 35. A threaded retainer 39 is fixedly connected to the top of the rectangular block 31. A threaded retainer 310 is threadedly connected to the inner wall of the threaded retainer 39. A connecting rod 310 is fixedly connected to the top of the threaded retainer 310. The top of the rod 311 is fixedly connected to a protective frame 312, which is made of transparent material. Under the action of the rotating rod 34, the grinding block 38 can be rotated, thereby grinding the weld. At the same time, under the action of the sliding rod 36, in conjunction with the annular groove 35, the rotating rod 34 can be guided and connected during rotation. Under the action of the threaded retainer 39 and the threaded retainer 310, the protective frame 312 can be installed, thereby preventing debris from flying upwards and hitting the user's eyes during the grinding process.
[0021] Working principle: like Figure 1-4 As shown: In use, rotating the operating block 23 causes the hollow screw 22 to move within the operating cylinder 21, which in turn causes the connecting plate 24 to move, allowing the grinding block 38 to move and thus adjusting the position of the grinding block 38. When the connecting plate 24 moves, it can drive the sliding rod 26 to move on the inner wall of the fixed cylinder 27, thereby limiting the connecting plate 24; Rotate and fix the threaded clamp 310 and the threaded clamp 39. At this time, start the drive motor 33 so that the rotating rod 34 can drive the grinding block 38 to move, which in turn can drive the sliding round rod 36 to slide on the inner wall of the annular groove 35, and thus cooperate with the grinding block 38 to perform grinding.
[0022] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
