Description

Technical Field

[0001] This utility model relates to the technical field of cutting tool processing, and in particular to a drilling device for tunnel boring machine cutting tools. Background Technology

[0002] A tunnel boring machine (TBM) is a large engineering machine used for excavating underground tunnels. The working principle of a TBM is that its cutterhead rotates at the front end, cutting through the ground and simultaneously propelling the machine forward, thus achieving tunnel excavation. The cutterhead of the TBM is equipped with cutting tools, and during the machining of these tools, mounting holes need to be drilled to install them onto the cutterhead.

[0003] Currently, fixed-size drill bits are typically used when drilling holes in tunnel boring machine cutters. Whenever a different sized mounting hole needs to be drilled in the cutter, the operator must first stop the current work, remove the existing drill bit from the machine, select a suitable new drill bit, and install it in place. This process is cumbersome and reduces work efficiency. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a drilling device for tunnel boring machines, which can flexibly switch to drill bits of different sizes, simplifying the operation process and thus effectively improving work efficiency.

[0006] To achieve the above objectives, this utility model proposes a drilling device for tunnel boring machines, comprising a worktable, a rotating mechanism, a support platform, and a clamping mechanism.

[0021] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0022] The drilling device for tunnel boring machines according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0023] like Figures 1-5 As shown, the tunnel boring machine cutter drilling device of this utility model embodiment may include a workbench 10, a rotating mechanism 30, a support platform 50 and a clamping mechanism 60.

[0024] The workbench 10 has a support 11 connected to one side of its top surface, and the support 11 is connected to an electric push rod 20.

[0025] The piston end of the electric push rod 20 is connected to the first driver 21, and the output end of the first driver 21 is connected to the plug 22.

[0026] It should be noted that the first driver 21 described in this embodiment can be a motor, and the cross-section of the insert 22 is square. The first driver 21 can drive the drill bit 43 to rotate and perform drilling operations on the tool.

[0027] The rotating mechanism 30 is set on the worktable 10. The rotating mechanism 30 is connected to the telescopic component 41. The telescopic component 41 is connected to the turntable 42. The turntable 42 is provided with multiple drill bits 43 in the circumferential direction. The top of the drill bit 43 is provided with a slot 44 that matches the insert block 22. The drill bit 43 is provided with a bearing 45. The drill bit 43 is rotatably connected to the turntable 42 through the bearing 45.

[0028] It should be noted that the multiple drill bits 43 are of different sizes. The rotating mechanism 30 can drive the turntable 42 to rotate at a certain angle, and the insert block 22 can be inserted into different slots 44 to switch to different drill bits 43. The telescopic component 41 can be set to adapt to the height change of the drill bit 43.

[0029] The support platform 50 is mounted on the workbench 10, and the clamping mechanism 60 is mounted on the support platform 50.

[0030] Specifically, the workers place the tunnel boring machine cutter on the support platform 50, so that the part to be drilled is below the drill bit 43, and then use the clamping mechanism 60 to clamp and fix the cutter.

[0031] Start the rotating mechanism 30 to drive the turntable 42 to rotate at a certain angle, so that the required drill bit 43 is moved below the insert block 22. Then, control the piston end of the electric push rod 20 to extend and drive the insert block 22 to move downward so that it is inserted into the slot 44 on the drill bit 43.

[0032] Then, the first driver 21 is activated, which drives the drill bit 43 to rotate. At the same time, the electric push rod 20 is activated, which drives the drill bit 43 to move downward, thereby performing drilling operations on the tool.

[0033] The tunnel boring machine cutting tool drilling device of this utility model embodiment can flexibly switch to different sized drill bits, simplifying the operation process and thus effectively improving work efficiency.

[0034] In one embodiment of this utility model, such as Figure 1 and Figure 3 As shown, the rotating mechanism 30 may include a drive box 31, a disc 32, an arc-shaped disc 33, an eccentric column 34, a conversion frame 35, a rotating shaft 37, and a second driver 38.

[0035] The drive box 31 is mounted on the worktable 10, the disc 32 is mounted inside the drive box 31, the arc-shaped disc 33 and the eccentric column 34 are respectively connected to the disc 32, the second driver 38 is mounted on the bottom surface of the worktable 10, the output shaft of the second driver 38 passes through the worktable 10 and is connected to the disc 32, the conversion frame 35 abuts against the arc-shaped disc 33, the conversion frame 35 is provided with a plurality of receiving slots 36 that match the eccentric column 34, one end of the rotating shaft 37 is connected to the conversion frame 35, and the other end passes through the drive box 31 and is connected to the telescopic assembly 41.

[0036] It should be noted that the second driver 38 described in this embodiment can be a motor. The second driver 38 can drive the disc 32, the arc disc 33 and the eccentric column 34 to rotate. When the eccentric column 34 rotates into the receiving slot 36 of the conversion frame 35, it will push the conversion frame 35 to rotate. Whenever the eccentric column 34 completes a round of entering and exiting the receiving slot 36, the conversion frame 35 and the turntable 42 will rotate at a certain angle, thereby switching to different drill bits.

[0037] In one embodiment of this utility model, such as Figure 1 As shown, the clamping mechanism 60 may include a mounting bracket 61, an adjusting bolt 62, and a pressure plate 63. The mounting bracket 61 is mounted on the support platform 50, the adjusting bolt 62 is threadedly connected to the mounting bracket 61, and the pressure plate 63 is rotatably connected to the end of the adjusting bolt 62.

[0038] It should be noted that by rotating the adjusting bolt 62, the pressure plate 63 can be moved, thereby clamping and fixing the tool to be drilled.

[0039] In one embodiment of this utility model, such as Figure 5 As shown, the telescopic assembly 41 may include a sleeve 411, a spring 412, and a moving rod 413. The sleeve 411 is connected to the rotating shaft 37, the moving rod 413 is slidably connected to the sleeve 411, and the spring 412 is connected between the moving rod 413 and the bottom wall of the sleeve 411.

[0040] It should be noted that the inner wall of the sleeve 411 is provided with two sliding grooves, and a slider is slidably connected in the sliding groove. The moving rod 413 is connected to the slider. Through the cooperation of the spring 412 and the moving rod 413, it can adapt to the height changes of the drill bit 43 and the turntable 42.

[0041] In one embodiment of this utility model, such as Figure 1 As shown, the support platform 50 is provided with a through hole 51, which is located below the drill bit 43.

[0042] Understandably, by setting through hole 51, drill bit 43 can pass through, thus avoiding damage to support platform 50.

[0043] In summary, the tunnel boring machine cutting tool drilling device of this utility model embodiment can flexibly switch to drill bits of different sizes, simplifying the operation process and thus effectively improving work efficiency.
