Description

Technical Field

[0001] This utility model relates to the field of shield tunneling tool technology, specifically to a positioning device for shield tunneling tool processing. Background Technology

[0002] The tunneling system in a tunnel boring machine (TBM) consists of the cutterhead and its drive system. The cutterhead is a rotating or rocking disc-shaped excavator, which is composed of cutting tools for excavating the strata, a panel for stabilizing the excavation face, an excavation trench, a rotating or rocking drive mechanism, and a bearing mechanism. During the processing of the TBM cutting tools, a positioning device is required to fix the TBM cutting tools so that subsequent processing equipment can process them.

[0003] Existing positioning devices typically use clamping in conjunction with positioning to ensure the stability of the workpiece during processing. The clamping mechanism fixes the cutting tool, and the positioning mechanism positions the workpiece for processing. However, when changing the processing position, the device needs to loosen the workpiece again for positioning, which requires the operator to move the entire workpiece, wasting a lot of time.

[0004] The aforementioned positioning device, because once the shield cutter is fixed, makes it difficult for operators to flexibly adjust the processing position of the cutter, results in a significant amount of time being spent by operators positioning the shield cutter, thus reducing the effectiveness of the device. Utility Model Content

[0005] This utility model proposes a positioning device for processing tunnel boring machine cutters, which solves the problem of difficulty in flexibly positioning tunnel boring machine cutters after placement in the prior art.

[0006] The technical solution of this utility model is as follows: A positioning device for processing tunnel boring machine cutters, comprising a placement plate, and further comprising:

[0007] The movable block is slidably connected inside the placement plate. A movable frame is mounted on the upper surface of the movable block, and a push rod motor is mounted on the upper surface of the movable frame, which can adjust the fixed frame up and down. The output end of the push rod motor passes through the interior of the movable frame. The fixed frame is mounted on the output end of the push rod motor. An auxiliary piece is mounted on the inner side of the fixed frame. The outer side of the first connecting piece is mounted on the inner side of the fixed frame. A fixed shaft is rotatably connected inside the first connecting piece. A connecting tube is mounted on the outer side of the first connecting piece. A connecting pin passes through the outer surface of the connecting tube. The outer surface of the fixed shaft passes through the connecting tube. One end of the connecting pin passing through the connecting tube abuts against the fixed shaft. The first connecting block is fixed to the outer surface of the fixed shaft. A telescopic rod is mounted on the inner side of the first connecting block, which can reduce the positioning range of the device. A second connecting block is mounted on the inner end of the telescopic rod. A second connecting piece is rotatably connected to the outer side of the second connecting block. A positioning plate is mounted on the lower surface of the second connecting piece.

[0008] As a preferred embodiment of the positioning device for tunnel boring machine tool processing described in this utility model, in order to retract the moving bar when the operator positions the processing position, a buffer spring is installed inside the fixed frame, and the moving bar is installed at the bottom end of the buffer spring.

[0009] As a preferred embodiment of the positioning device for tunnel boring machine tool processing described in this utility model, in order for the operator to clean the workpiece surface while moving the fixed frame, the moving bar is slidably connected to the inside of the fixed frame, and a cleaning brush is installed on the lower surface of the moving bar.

[0010] As a preferred embodiment of the positioning device for tunnel boring machine tool processing described in this utility model, in order to prevent the cleaning brush from bending under the action of the buffer spring, a support rod is installed on the lower surface of the moving bar, and the support rod is rotatably connected with ball bearings, the number of which is two sets.

[0011] In a preferred embodiment of the positioning device for tunnel boring machine tool processing described in this utility model, in order to prevent the workpiece from loosening during processing, an anti-slip strip is installed on the lower surface of the fixing frame, and an anti-slip pad is fixedly connected to the lower surface of the positioning plate.

[0012] As a preferred embodiment of the positioning device for tunnel boring machine tool processing described in this utility model, in order to prevent the moving frame from becoming loose during the workpiece processing process, a bolt is threaded through the upper surface of the moving block, and one end of the bolt passes through the moving block and abuts against the placement plate.

[0013] The working principle and beneficial effects of this utility model are as follows:

[0014] In this invention, the first connecting block flips downward along the first connecting piece via a fixed shaft, and then extends inward via a telescopic rod to move the positioning plate to the processing position. Compared with the prior art of directly processing after clamping the workpiece, this device can reduce the processing range of the operator, accurately locate the processing position on the workpiece surface, and improve the effectiveness of the device.

[0015] In this invention, the rotating threaded rod drives the mounting block to move inward along the placement plate. The inward movement of the mounting block drives the contact frame to move inward and contact the shield cutter. Compared with the direct positioning of the shield cutter in the prior art, this device can fix the shield cutter through the contact frame and contact plate, which can prevent the cutter from becoming loose during the positioning and processing process by the operator.

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0023] like Figures 1-4 As shown, this embodiment proposes a positioning device for processing tunnel boring machine cutters, including a placement plate 1, a moving block 2, a moving frame 3, a push rod motor 4, a fixed frame 5, an auxiliary piece 6, a first connecting piece 7, a fixed shaft 8, a connecting pipe 9, a connecting pin 10, a first connecting block 11, a telescopic rod 12, a second connecting block 13, a second connecting piece 14, and a positioning plate 15.

[0024] like Figure 2 As shown, the movable block 2 is slidably connected inside the placement plate 1. A bolt is threaded through the upper surface of the movable block 2, and one end of the bolt passes through the movable block 2 and abuts against the placement plate 1. After the movable block 2 is moved, the bolt passes through its interior and abuts against the placement plate 1. A movable frame 3 is installed on the upper surface of the movable block 2, and a push rod motor 4 is installed on the upper surface of the movable frame 3. The output end of the push rod motor 4 passes through the interior of the movable frame 3. A fixed frame 5 is installed on the output end of the push rod motor 4. The output end of the push rod motor 4 moves downward, causing the fixed frame 5 to move downward and contact the workpiece. An anti-slip strip 20 is installed on the lower surface of the fixed frame 5, and an anti-slip pad is fixedly connected to the lower surface of the positioning plate 15 to prevent the workpiece from becoming loose during the operator's processing. An auxiliary piece 6 is installed on the inner side of the fixed frame 5, and the outer side of the first connecting piece 7 is installed on... On the inner side of the fixed frame 5, the first connecting piece 7 is rotatably connected to the fixed shaft 8. The outer side of the first connecting piece 7 is equipped with a connecting pipe 9. A connecting pin 10 passes through the outer surface of the connecting pipe 9. The outer surface of the fixed shaft 8 passes through the connecting pipe 9. One end of the connecting pin 10 passes through the connecting pipe 9 and abuts against the fixed shaft 8. The first connecting block 11 is fixed to the outer surface of the fixed shaft 8. The inner side of the first connecting block 11 is equipped with a telescopic rod 12. It should be noted that the telescopic rod 12 is a common telescopic rod on the market. Since the telescopic rod 12 is inclined downward after it is extended, the situation where the positioning plate 15 shortens the telescopic rod 12 after contacting the workpiece will not occur. The inner end of the telescopic rod 12 is equipped with a second connecting block 13. The outer side of the second connecting block 13 is rotatably connected to a second connecting piece 14. The lower surface of the second connecting piece 14 is equipped with a positioning plate 15.

[0025] like Figure 2As shown, a buffer spring 16 is installed inside the fixed frame 5. A moving strip 17 is installed at the bottom end of the buffer spring 16. The moving strip 17 is slidably connected inside the fixed frame 5. A cleaning brush 18 is installed on the lower surface of the moving strip 17. A support rod 19 is installed on the lower surface of the moving strip 17. Two sets of ball bearings are rotatably connected inside the support rod 19. When the fixed frame 5 moves downward, the support rod 19 pushes the moving strip 17 upward, and the moving strip 17 enters the fixed frame 5. When the fixed frame 5 moves upward, the buffer spring 16 pushes the moving strip 17 out. During this process, the cleaning brush 18 can be hidden and extended with the movement of the fixed frame 5, which can prevent it from affecting the operator's normal positioning of the workpiece. It should be noted that the length of the support rod 19 is less than the length of the cleaning brush 18. Since the ball bearings at the bottom end of the support rod 19 support the whole, only a part of the ball bearings are exposed at the bottom when in use, and they roll along the workpiece. Therefore, the ball bearings and the support rod 19 will not affect the normal cleaning of the cleaning brush 18.

[0026] In this embodiment, as Figures 3-4 As shown, a connecting piece 21 is slidably connected inside the placement plate 1. A threaded rod 22 is rotatably connected inside the connecting piece 21. A control lever is installed at the left end of the threaded rod 22. Rotating the control lever causes the threaded rod 22 to rotate, which in turn causes the mounting block 24 to move inward, so that the contact frame 25 moves inward and contacts the workpiece. The mounting block 24 is threadedly connected to the outer surface of the threaded rod 22. The mounting block 24 is slidably connected inside the placement plate 1. A fixing pin 23 is threaded through the upper surface of the connecting piece 21. One end of the fixing pin 23, which is inserted into the connecting piece 21, abuts against the threaded rod 22. After the threaded rod 22 has rotated, the fixing pin 23 is inserted into the connecting piece 21, and then the fixing pin 23 is tightened clockwise to secure the threaded rod. 22 is fixed in place. A contact frame 25 is installed on the upper surface of the mounting block 24. A contact block 26 is slidably connected inside the contact frame 25. A contact plate 28 is installed on the inner side of the contact block 26. An auxiliary spring 27 is installed inside the contact frame 25. The inner end of the auxiliary spring 27 is installed on the outer side of the contact block 26. The contact plate 28 is moved outward to drive the contact block 26 to move outward. The contact block 26 moves outward along the inside of the contact frame 25. The outward movement of the contact block 26 compresses the auxiliary spring 27. A collection box 29 is installed on the outer side of the contact frame 25. A baffle plate 30 is installed inside the collection box 29. An inclined plate 31 is installed inside the collection box 29. A support leg 32 is installed on the lower surface of the placement plate 1.

[0027] In this embodiment, when the device needs to be assembled, the connecting piece 21 is slid in along the placement plate 1, and the threaded rod 22 and the mounting block 24 are placed into the placement plate 1.

[0028] When it is necessary to fix the workpiece, place the workpiece on the upper surface of the placement plate 1, operate the contact plate 28 to move outward, causing the contact block 26 to move outward. The contact block 26 moves outward and compresses the auxiliary spring 27. Operate the control lever to rotate, causing the threaded rod 22 to rotate. The threaded rod 22 rotates, causing the mounting block 24 to move inward along the placement plate 1. The mounting block 24 moves inward, causing the contact frame 25 to move inward. The contact frame 25 moves inward and contacts the workpiece. Release the contact plate 28, so that the auxiliary spring 27 rebounds and causes the contact block 26 to move inward along the contact frame 25. The contact block 26 moves inward, causing the contact plate 28 to move inward and contacts the workpiece. After the movement is complete, operate the fixing pin 23 to insert into the connecting piece 21, and then rotate the fixing pin 23 clockwise to press against the threaded rod 22.

[0029] When workpiece positioning is required, the manipulator moves the movable block 2 inward along the placement plate 1. This inward movement of the movable block 2 causes the movable frame 3 to move inward, which in turn causes the push rod motor 4 to move inward. The push rod motor 4 then moves the fixed frame 5 inward. After positioning, the manipulator bolt is screwed clockwise into the movable block 2 to press against the placement plate 1. The push rod motor 4 is then activated. The output end of the push rod motor 4 moves downward, causing the fixed frame 5 to move downward. This downward movement of the fixed frame 5 causes the auxiliary piece 6 to move downward, which in turn causes the first connecting piece 7 to move downward. The downward movement of the fixed frame 5 brings the ball bearings into contact with the workpiece and drives the support rod 19 to push the movable strip 17 upward, causing the movable strip 17 to move upward along the fixed frame 5, thus retracting the cleaning brush 18 into the fixed frame 5. The downward movement of the fixed frame 5 then causes the anti-slip strip 20 to move downward. 20 moves downward to contact the workpiece, pulls out the connecting pin 10, manipulates the telescopic rod 12 to flip downward through the first connecting block 11, the first connecting block 11 flips downward to drive the fixed shaft 8 to rotate along the inside of the first connecting piece 7 and the connecting pipe 9, the telescopic rod 12 flips downward to drive the second connecting block 13 to flip downward, the second connecting block 13 flips downward to drive the second connecting piece 14 to flip downward, so that the positioning plate 15 contacts the workpiece, and positions the workpiece processing position. When the positioning range remains unchanged, the output end of the push rod motor 4 only needs to lift the fixed frame 5 upward, move the position of the moving frame 3, and then put the fixed frame 5 down. During this process, when the cleaning brush 18 extends, it can sweep the debris on the surface of the workpiece. Some of the debris enters the collection box 29 and is discharged along the inclined plate 31, preventing most of the debris from entering the placement plate 1 and affecting the rotation of the threaded rod 22.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
