Description

Technical Field

[0001] This invention relates to the field of cutting head processing technology, and in particular to a contour milling adapter for the outer periphery of a tunneling machine cutting head. Background Technology

[0002] The contour milling adapter for the outer periphery of the tunneling machine cutting head is a specialized device for precisely machining the complex spatial curved surface of the cutting head. Its core function is to achieve high-precision milling of the outer periphery of the cutting head through contour milling technology, ensuring the geometric accuracy and surface quality of the cutting tooth mounting surface.

[0003] In the actual production process of milling machining by the cutting head of a tunneling machine, a large number of chips are generated due to the characteristics of milling operations. These chips are not only small in size but also have a special shape, mostly being rolled. Meanwhile, to ensure the smooth progress of the milling process and improve machining quality, coolant is usually used to cool and lubricate the machining area. To achieve the recycling of coolant and the centralized treatment of chips, a separation module is specially set up on the milling machine to separate chips from coolant. This module mainly relies on a filter screen to perform the screening work, allowing the coolant to pass through the filter screen for continued recycling, while intercepting the chips on the filter screen surface. However, in actual use, the existing separation module has obvious drawbacks. Because the chips have a rolled structure, this special shape causes the chips to flow with the coolant to the filter screen. During processing, debris can easily get caught in the mesh or structural frame of the filter screen. Once some debris gets caught, it quickly attracts more debris to accumulate there. As processing continues, the debris accumulates and soon completely clogs the mesh. Once the filter screen is clogged, the coolant cannot pass through smoothly, causing coolant to accumulate on one side of the screen while the other side cannot receive enough coolant. This not only seriously affects the normal circulation of coolant and reduces the cooling and lubrication effect of coolant on the milling parts, thus affecting the processing quality, but may also cause the milling machine to malfunction due to overheating, shortening the service life of the equipment. In addition, after the filter screen is clogged, it is necessary to frequently stop the machine to clean the filter screen, which not only increases the labor intensity of workers, but also reduces production efficiency and increases production costs.

[0004] Therefore, it is necessary to design a contour milling adapter for the outer periphery of the tunneling machine cutting head to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a contour milling adapter for the outer periphery of the tunneling machine cutting head.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A contour milling adapter for the outer periphery of a tunneling machine cutting head includes a base, on which a milling machine is fixed. A cleaning port is provided on the top surface of the base. A guide bucket is fixed on the base. A fixed seat is fixed inside the base. Two debris collection containers are arranged inside the fixed seat. A filter assembly is provided on the fixed seat. The filter assembly consists of two filter structures, each including a mounting frame. The two mounting frames are connected by two connecting plates, with a gap between them. A buckle plate is fixed to both mounting frames, facing the gap between them. Two mounting rods are fixed to each mounting frame, located on the same side of the frame. The fixed base is provided with a driving component for driving the two mounting frames to move. The fixed base is also provided with four guide components, which are respectively distributed at the four corners of the top of the fixed base.

[0007] As a preferred embodiment of the present invention, the filter structure further includes a fixed rod and several movable rods. The mounting frame is slidably disposed inside the fixed base and is located at the top of the fixed base. The mounting frame has four strip-shaped openings, which are arranged in pairs and located on both sides of the mounting frame. The fixed rod is fixed in the middle of the mounting frame. Several movable rods are slidably disposed on the mounting frame. Each movable rod has a connecting post fixed at both ends. The connecting post slides in the strip-shaped opening. Each connecting post is fixedly fitted with a limiting ring. Each movable rod has a protrusion fixed on it. The fixed rod also has a protrusion fixed on it. Two adjacent movable rods are connected by a connecting rope. The fixed rod and the movable rod of the adjacent fixed rod are also connected by a connecting rope. Each movable rod located at the end of the mounting frame is fixed with a horizontal bar, and each horizontal bar is fixed with a vertical bar. The two movable rods located at both ends of the mounting frame are connected to the two mounting rods by tension springs.

[0008] As a preferred embodiment of the present invention, a plurality of the movable rods are evenly distributed on both sides of the fixed rod.

[0009] As a preferred embodiment of the present invention, the limiting ring is fitted with the mounting frame, and both ends of the movable rod are fitted with the mounting frame.

[0010] As a preferred embodiment of the present invention, the drive assembly includes a motor and two brackets. Both brackets are fixed to the side of the fixed base. The motor is mounted on the side of the fixed base. A lead screw is rotatably mounted between the two brackets. The lead screw is connected to the output shaft of the motor. A movable seat is threaded onto the lead screw. The movable seat is connected to the buckle plate through a mounting plate.

[0011] As a preferred embodiment of the present invention, the guide component includes a fixing plate, which is fixed inside the fixing seat. The fixing plate is provided with a first sliding groove, a second sliding groove and a third sliding groove, which are connected to form a guide channel.

[0012] As a preferred embodiment of the present invention, the first slide and the third slide are both arranged along the moving direction of the mounting frame, and the second slide is inclined relative to the first slide and the third slide.

[0013] As a preferred embodiment of the present invention, the four vertical rods are respectively positioned opposite the four first sliding grooves.

[0014] As a preferred embodiment of the present invention, the protrusion is provided with an arc surface that is adapted to the movable rod.

[0015] As a preferred embodiment of the present invention, in the initial state, one of the mounting frames is located directly below the guide bucket, and the other mounting frame is directly opposite one of the debris collection containers.

[0016] The present invention has the following beneficial effects: In existing technologies, because the debris has a rolled structure, it is easy to get caught on the filter screen or structural frame, leading to debris accumulation and clogging of the filter screen. This affects coolant circulation, processing quality, and may even cause machine tool failure and shorten equipment life. This solution uses a special filter structure consisting of a fixed rod and several movable rods. Protrusions on the movable rods create gaps between adjacent movable rods and between the fixed rod and its adjacent movable rod. Coolant can flow into the fixed seat through these gaps, while debris is trapped on the movable and fixed rods. When the mounting frame moves above the debris collection container, the movable rods spread out, increasing the distance between adjacent movable rods. The trapped debris falls into the debris collection container through the larger gaps, achieving automatic debris collection. This structure avoids the problem of traditional filters being easily clogged by rolled debris, ensuring normal coolant circulation, improving the cooling and lubrication effect of the coolant on the milling parts, helping to ensure processing quality, reduce machine tool failure, and extend equipment life.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Example 1: This example describes the contour milling adapter for the outer periphery of the tunneling machine cutting head, as disclosed in this example. Figure 1-5 and Figure 7 The system includes a base 1, on which a milling machine 2 is fixed. The milling machine 2 is used to mill the cutting head of the tunneling machine. The top surface of the base 1 is provided with a cleaning port. A guide bucket 3 is fixed on the base 1. A fixed seat 4 is fixed inside the base 1. Two debris collection containers 5 are set inside the fixed seat 4. The two debris collection containers 5 are located at both ends of the fixed seat 4. The debris collection containers 5 are detachably mounted on the fixed seat 4 to facilitate the centralized cleaning of debris in the debris collection containers 5 by the staff. The specific connection structure between the debris collection containers 5 and the fixed seat 4 is existing technology and will not be described in detail here.

[0021] A filter assembly is provided on the fixed base 4. The filter assembly consists of two filter structures, each including a mounting frame 61. The mounting frame 61 is slidably disposed inside the fixed base 4 and is located at the top of the fixed base 4. The mounting frame 61 has four strip-shaped openings 611, which are arranged in pairs on both sides of the mounting frame 61. A fixing rod 64 is fixed in the middle of the mounting frame 61. Several movable rods 651 are slidably disposed on the mounting frame 61, and are evenly distributed on both sides of the fixing rod 64. Each movable rod... Both ends of the rod 651 are fixed with connecting posts 652, which slide within the strip-shaped opening 611. Each connecting post 652 is fitted with a limiting ring 653, which fits against the mounting frame 61. Both ends of the movable rod 651 are fitted against the mounting frame 61. The two limiting rings 653 provide a limit for the movable rod 651, preventing it from falling off the mounting frame 61 and ensuring its stability during movement. Each movable rod 651 is fixed with a protrusion 654, and the fixed rod 64 is also fixed with a protrusion 654. Figure 7 As shown, when the movable rods 651 are in the retracted state, the protrusions 654 act as spacers between adjacent movable rods 651, creating a gap between them. This gap allows coolant to flow through, while debris is intercepted by the movable rods 651. At this time, the fixed rod 64 and the movable rods 651 work together to separate the debris from the coolant. For the fixed rod 64 and the movable rods 651 adjacent to it, the protrusions 654 on the fixed rod 64 have the same function: to create a gap between the fixed rod 64 and its adjacent movable rods 651. The two adjacent movable rods 651 are connected by a connecting rope 655, and the fixed rod 64 and the movable rods 651 adjacent to it are also connected by a connecting rope 655.

[0022] Two mounting rods 66 are fixed on the mounting frame 61, and the two mounting rods 66 are located on the same side of the mounting frame 61. Two movable rods 651 located at both ends of the mounting frame 61 are connected to the two mounting rods 66 by tension springs 67. In the initial state, under the elastic force of the two tension springs 67, several movable rods 651 are in a retracted state. For the two filter structures, the two mounting frames 61 are connected by two connecting plates 62. There is a gap between the two mounting frames 61. A buckle plate 63 is fixed on both mounting frames 61, and the buckle plate 63 is set directly opposite the gap between the two mounting frames 61. The buckle plate 63 is set to prevent debris from entering the gap between the two mounting frames 61. In the initial state, one mounting frame 61 is located directly below the guide bucket 3, and the other mounting frame 61 is directly opposite one of the debris collection containers 5.

[0023] The implementation principle of this embodiment is as follows: When the contour milling adapter for the outer periphery of the tunneling machine cutting head is working, the milling machine 2 performs milling processing on the tunneling machine cutting head. During the processing, the debris and coolant generated will enter the interior of the base 1 through the cleaning port on the top surface of the base 1 and the guide bucket 3. A fixed seat 4 is fixed inside the base 1. Debris collection containers 5 are detachably installed at both ends of the fixed seat 4 to collect debris for centralized cleaning by workers. A filter assembly consisting of two filter structures is installed on the fixed seat 4. In each filter structure, the mounting frame 61 is slidably installed inside the fixed seat 4 and Located at the top, the mounting frame 61 has four strip-shaped openings 611, which are located in pairs on both sides of the mounting frame 61. A fixed rod 64 is fixed in the middle, and several movable rods 651 are slidably arranged on both sides of the fixed rod 64. Each movable rod 651 has a connecting post 652 fixed at both ends. The connecting post 652 slides in the strip-shaped opening 611 and is fitted with a limiting ring 653. The limiting ring 653 fits in close to the mounting frame 61, and the two ends of the movable rod 651 also fit in close to the mounting frame 61. The two limiting rings 653 prevent the movable rod 651 from falling off the mounting frame 61 and ensure the stable movement of the movable rod 651.

[0024] Each movable rod 651 and fixed rod 64 is fixed with a protrusion 654. When the movable rods 651 are in the retracted state in the initial state, the protrusion 654 creates a gap between adjacent movable rods 651 and between the fixed rod 64 and its adjacent movable rod 651. This gap allows coolant to flow through, while debris is intercepted by the movable rods 651. This allows the fixed rod 64 and the movable rods 651 to jointly screen debris and coolant. Adjacent movable rods 651 and the fixed rod 64 and its adjacent movable rod 651 are connected by connecting ropes 655. Two mounting rods 66 located on the same side are fixed on the mounting frame 61. The movable rods 651 located at both ends of the mounting frame 61 are connected to the two mounting rods 66 by tension springs 67. Under the elastic force of the two tension springs 67, the movable rods 651 are initially kept in a retracted state. The mounting frames 61 of the two filter structures are connected by two connecting plates 62 with a gap. The fastener 63, which is fixed together, is set directly opposite the gap to prevent debris from entering the gap between the two mounting frames 61. In this way, when the coolant and debris pass through the filter assembly, the debris is intercepted on the movable rods 651 and the fixed rods 64, while the coolant flows into the gap between the two debris collection containers 5, realizing the separation and collection of debris and coolant.

[0025] Example 2: Based on Example 1, this example discloses a contour milling adapter for the outer periphery of a tunneling machine cutting head, such as... Figure 4 and Figure 6As shown, a drive assembly is provided on the fixed base 4. The drive assembly is used to drive the two mounting frames 61 to move. The drive assembly includes a motor and two brackets. The two brackets are fixed to the side of the fixed base 4. The motor is mounted on the side of the fixed base 4. A lead screw is rotatably installed between the two brackets. The lead screw is connected to the output shaft of the motor. A movable seat is threaded onto the lead screw. The movable seat is connected to the buckle plate 63 through the mounting plate. When the motor runs, it drives the lead screw to rotate. When the lead screw rotates, it drives the movable seat to move. When the movable seat moves, it drives the buckle plate 63 to move through the mounting plate, so that the two mounting frames 61 move synchronously. For ease of understanding, the two mounting frames 61 are defined as mounting frame 61A and mounting frame 61B, respectively. The two debris collection containers 5 are defined as container A and container B. In the initial state, mounting frame 61A is located directly below the guide bucket 3, and mounting frame 61B is set directly opposite container A. When the motor runs, the two mounting frames 61 move, so that mounting frame 61A moves to the position directly opposite container B, and mounting frame 61B moves to the position directly below the guide bucket 3.

[0026] A horizontal bar 6511 is fixed to each movable rod 651 located at the end of the mounting frame 61. A vertical bar 6512 is fixed to each horizontal bar 6511. Four guide components are provided on the fixed base 4, which are distributed at the four corners of the top of the fixed base 4. Each guide component includes a fixed plate 71, which is fixed inside the fixed base 4. The fixed plate 71 has a first sliding groove 711, a second sliding groove 712, and a third sliding groove 713. The first sliding groove 711, the second sliding groove 712, and the third sliding groove 713 together form a total of The first slide 711 and the third slide 713 are both arranged along the moving direction of the mounting frame 61. The second slide 712 is inclined relative to the first slide 711 and the third slide 713. For the movable rod 651 located at the end of the mounting frame 61, the vertical rod 6512 on it is positioned directly opposite the first slide 711. When the mounting frame 61 moves toward the debris collection container 5, the vertical rod 6512 will slide into the first slide 711 and then slide along the second slide 712. Figure 7 As shown, since the second slide 712 is inclined, the vertical rod 6512 will drive the corresponding movable rod 651 to move along the length of the mounting frame 61 when it moves. The two adjacent movable rods 651 are connected by a connecting rope 655. Therefore, the moving movable rod 651 can pull the other movable rods 651 to move through several connecting ropes 655, and finally cause several movable rods 651 to spread out. When the mounting frame 61 moves above the debris collection container 5, several movable rods 651 are in a spread-out state. In this case, the distance between two adjacent movable rods 651 becomes larger, and the debris intercepted by several movable rods 651 will fall into the debris collection container 5 through the large gap between two adjacent movable rods 651, realizing the automatic collection of debris.

[0027] The implementation principle of this embodiment is as follows: When the milling machine 2 mills the cutting head of the tunneling machine, the generated debris and coolant enter the interior of the base 1 through the cleaning port and guide bucket 3 on the top surface of the base 1. In the initial state, the mounting frame 61A is located directly below the guide bucket 3, and the mounting frame 61B is set directly opposite the container A. At this time, under the elastic force of the tension spring 67, several movable rods 651 in the two filter structures are in a retracted state. The protrusions 654 on the movable rods 651 create gaps between adjacent movable rods 651 and between the fixed rod 64 and its adjacent movable rods 651. The coolant can flow into the debris collection container 5 below through these gaps, and the debris is intercepted on the movable rods 651 and the fixed rod 64. When it is necessary to clean the debris, the motor in the drive assembly is started. The motor drives the lead screw connected to its output shaft to rotate. The rotation of the lead screw drives the movable seat threaded on it to move. The movable seat drives the buckle plate 63 to move through the mounting plate. Two mounting frames 61 are connected by a connecting plate 62 and are also connected to a buckle plate 63, which allows the two mounting frames 61 to move synchronously. Ultimately, mounting frame 61A moves to a position directly opposite container B, and mounting frame 61B moves to a position directly below the guide bucket 3. During the movement of the mounting frames 61, the vertical rod 6512 on the movable rod 651 at the end of the mounting frame 61 will slide into the first slide groove 711 as the mounting frame 61 moves toward the debris collection container 5, and then slide along the inclined second slide groove 712. Due to the inclined setting of the second slide groove 712, the vertical rod 6512 will drive the corresponding movable rod 651 to move along the length direction of the mounting frame 61 when it moves. Since adjacent movable rods 651 are connected by connecting ropes 655, the moving movable rod 651 can pull the other movable rods 651 to move through several connecting ropes 655, ultimately causing several movable rods 651 to disperse.

[0028] When the mounting frame 61 moves above the debris collection container 5, several movable rods 651 are spread out, and the gap between two adjacent movable rods 651 becomes larger. The debris that was previously caught on the movable rods 651 and the fixed rod 64 will fall into the debris collection container 5 below through the large gap between the adjacent movable rods 651, realizing automatic collection of debris. Meanwhile, the coolant can still flow into the debris collection container 5 through the gap between the movable rods 651 and the fixed rod 64, completing the separation of debris and coolant. The whole process replaces the traditional filter screen separation structure and effectively avoids the situation of debris clogging the filter screen.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
