[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1 As shown, a boring device for the inner side of an excavator track roller includes a support platform 1, a support platform 2 fixedly connected to the front end of the support platform 1, a lifting mechanism 3 fixedly connected to the lower end of the support platform 1, a boring mechanism 8 fixedly connected to the upper end of the lifting mechanism 3, a worktable 5 fixedly connected to the upper end of the support platform 2, a clamping mechanism 4 fixedly connected to the front part of the upper end of the worktable 5, a track roller 7 placed in the middle of the upper end of the worktable 5, and a filter assembly 6 fixedly connected to the lower end of the worktable 5.

[0025] In the specific implementation process of this utility model, firstly, the chain roller 7 is placed on the workbench 5. Then, by rotating the internal structure of the clamping mechanism 4, the chain roller 7 can be fixed above the workbench 5. Then, by rotating the internal structure of the lifting mechanism 3, the height of the boring mechanism 8 is adjusted. Then, the internal drive structure of the boring mechanism 8 is activated, and the boring mechanism 8 performs boring on the chain roller 7. During the boring process, the boring mechanism 8 can flush the waste generated during the boring process into the filter assembly 6. The filter assembly 6 can separate the cutting material and wastewater, so that the cutting material can be reused.

[0026] Specifically, in order to secure the track roller 7, refer to Figure 4 and Figure 5 In this solution, the clamping mechanism 4 includes a vertical plate 41, which is fixedly connected to the front side of the upper end of the workbench 5. A horizontal plate 42 is fixedly connected to the middle of the front end of the vertical plate 41. Fixing blocks 43 are fixedly connected to the left and right sides of the upper end of the horizontal plate 42. A bidirectional threaded rod 44 is rotatably connected between the opposing surfaces of the two fixing blocks 43. C-shaped blocks 45 are threadedly connected to the left and right sides of the outer surface of the bidirectional threaded rod 44. Clamping blocks 46 are fixedly connected to the lower rear ends of the two C-shaped blocks 45.

[0027] In the above process, the chain roller 7 is placed on the placement block at the top of the workbench 5. Then, the turntable on the left side of the bidirectional threaded rod 44 is rotated to drive the bidirectional threaded rod 44 to rotate. The rotation of the bidirectional threaded rod 44 drives the two C-shaped blocks 45 to move closer to each other, so that the two C-shaped blocks 45 drive the two clamping blocks 46 to move closer to each other to clamp and fix the chain roller 7.

[0028] Specifically, in order to achieve the purpose of adjusting the height of the boring mechanism 8, refer to Figure 3 In this scheme, the lifting mechanism 3 includes a fixed box 31 and a fixed plate 35. The fixed box 31 is fixedly connected to the lower end of the outer surface of the support platform 1. The fixed plate 35 is fixedly connected to the upper end of the support platform 1. Support columns 36 are fixedly connected to the four corners of the upper end of the fixed plate 35. Sliding columns 37 are slidably connected to the inner cavity of the support columns 36. A worm gear 32 is rotatably connected to the middle of the bottom wall of the inner cavity of the fixed box 31. A worm 33 is meshed with the front side of the outer surface of the worm gear 32. A lead screw 34 is threadedly connected to the middle of the worm gear 32.

[0029] Furthermore, a support plate 81 is fixedly connected to the upper ends of several sliding columns 37, and the upper end of the lead screw 34 extends through the support platform 1 and the lower end of the fixing plate 35 to the outside and is fixedly connected to the lower end of the support plate 81.

[0030] In the above, the turntable at the left end of the rotating fixed box 31 drives the worm 33 to rotate, which in turn drives the worm wheel 32 to rotate. Then, the rotation of the worm wheel 32 drives the lead screw 34 to rise in the inner cavity of the worm wheel 32, which lifts the support plate 81 upward. The support plate 81 then drives several sliding columns 37 to lift upward, ensuring the levelness of the support plate 81.

[0031] Specifically, in order to achieve the purpose of boring the track roller 7, refer to Figure 2 In this scheme, the boring mechanism 8 includes a support plate 81, which is fixedly connected to the upper end of the lifting mechanism 3. Slide bars 82 are fixedly connected to the left and right sides of the upper end of the support plate 81. A hydraulic cylinder 83 is fixedly connected to the rear part of the upper end of the support plate 81. A slide plate 84 is slidably connected to the upper end of the outer surfaces of the two slide bars 82. A partition plate 85 is fixedly connected to the rear side of the upper end of the slide plate 84. A motor 86 is fixedly connected to the middle of the rear end of the partition plate 85. A boring tool 87 is rotatably connected to the middle of the front end of the partition plate 85. A water tank 88 is fixedly connected to the left side of the front end of the slide plate 84. A water pump 89 is fixedly connected to the upper front end of the water tank 88.

[0032] Furthermore, the output end of the motor 86 is fixedly connected to the rear end of the boring bar 87 through the rear end of the partition 85 via a coupling, and the output end of the water pump 89 is fixedly connected with a bend.

[0033] In the above process, the inner cavity of the water tank 88 is first filled with coolant. Then, the hydraulic cylinder 83 is started, which pushes the slide plate 84 to slide forward on the slide bar 82, so that the front end of the boring tool 87 contacts the surface of the support roller 7. Then, the motor 86 is started to drive the boring tool 87 to rotate and bore the support roller 7. At the same time, the water pump 89 is started to pump out coolant from the bend pipe to cool the boring tool 87 and wash away the cutting material generated during the boring process.

[0034] The specific installation method, circuit connection method, and control method of the hydraulic cylinder 83 used above are all conventional designs, which only need to satisfy the requirement of pushing the slide plate 84 to move. This utility model will not elaborate further.

[0035] The specific installation method, circuit connection method, and control method of the water pump 89 used above are all conventional designs, which only need to be able to pump out the coolant in the inner cavity of the water tank 88. This utility model will not elaborate further.

[0036] Specifically, in order to achieve the separation of cutting material and coolant, refer to Figure 6In this solution, the filter assembly 6 includes an annular groove 61 and a housing 63. The annular groove 61 is located on the upper end of the workbench 5. A hole 62 is provided in the middle of the front side of the bottom wall of the inner surface of the annular groove 61. The housing 63 is fixedly connected to the lower end of the workbench 5. A filter box 64 is slidably connected to the upper front end of the housing 63, and a liquid storage tank 65 is slidably connected to the lower front end of the housing 63.

[0037] In the above process, after the coolant washes over the sprocket 7, the coolant will slide directly into the inner cavity of the annular groove 61 due to gravity. Then, the flow of the coolant will drive the cut material to flow into the hole 62, so that the coolant carrying the cut material falls down into the filter box 64 through the hole 62. The filter box 64 can retain the cut material inside the filter box 64, and then the coolant will fall directly into the inner cavity of the liquid storage tank 65 through the filter box 64 to achieve the purpose of separation.

[0038] It should be noted that the specific installation method, circuit connection method, and control method of the motor 86 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
