It is located at the front of the shield machine and is used to cut the soil. The cutter is generally installed on the cutterhead for excavating the soil layer. After searching, the Chinese patent with the announcement number CN221773532U discloses an assembly device for a shield machine cutter, including a driving assembly, a transmission assembly and a material discharge assembly, wherein the driving assembly includes a base, a driving component and a rotating shaft, wherein the driving component is arranged in the base, and the rotating shaft is arranged on the output end of the driving component, and the transmission assembly includes a chassis, two fastening mechanisms, an annular plate and a plurality of lifting members, wherein the chassis is arranged on the rotating shaft, and the chassis is rotatably arranged on the base, the annular plate is arranged on the chassis, the two fastening mechanisms are symmetrically arranged between the chassis and the annular plate, and the plurality of lifting members are arranged on the chassis.

However, the above scheme still has shortcomings when it is actually used: During the tool installation process of the shield machine cutterhead, tool installation positions are provided from the edge to the center area of ​​the cutterhead. However, the existing material discharge assembly can only install the tool at a preset fixed position when the tool is freed from the constraint and freely falls onto the surface of the rotating cutterhead.

[0015] The above technical solution of the present invention has the following beneficial technical effects: 1. The present invention places the cutter body in the loading and blanking assembly, and then drives the loading frame to rotate through the driving part on the driving assembly to adjust the position of the loading frame. Subsequently, the loading and blanking assembly is driven by the electric slide rail to move horizontally to a designated position above the cutter disc along the electric slide rail, and the falling of the cutter body is controlled by the loading and blanking assembly to fall to the corresponding position of the cutter disc. This process not only improves the accuracy of the installation position of the cutter body, but also enhances the automation and flexibility of the installation process, and avoids the problem of inaccurate installation caused by the traditional blanking assembly that can only install the cutter body at a preset fixed position, thereby ensuring that the tool layout of the shield machine cutter disc meets the design requirements; 2. The knife body is prone to impact the surface of the cutter disc due to its own weight during the falling process, which in turn causes the problem of blade damage. The present invention installs an annular buffer assembly at the bottom of the loading and blanking assembly. When the knife body falls from the loading and blanking assembly, it will first fall into the first ring body of the annular buffer assembly. At this time, the rod-type magnetic limiter extending into the first ring body can play a bearing role on the knife body to prevent it from directly impacting the surface of the cutter disc. At the same time, the elastic member between the loading and blanking assembly and the first ring body can buffer the knife body to further reduce the impact force. After completing the buffering, the electromagnet is energized to generate magnetic suction, so that the magnetic block approaches the electromagnet, driving the limit rod to enter the fixed tube, thereby releasing the bearing on the knife body, allowing it to fall smoothly to the installation position on the surface of the cutter disc, effectively avoiding damage to the blade due to impact, and ensuring the integrity and installation quality of the knife body; 3. After the cutter body falls onto the cutter disc surface, the cutter body is welded and fixed by the annular welding assembly at the bottom of the annular buffer assembly. To prevent the cutter body from shifting during welding, the electromagnet loses its magnetism by powering off. Under the elastic force of the spring, the magnetic block and the limit rod are automatically reset to the first ring body. Subsequently, the loading frame and the loading and blanking assembly are driven downward by the driving assembly, so that the limit rod is pressed against the cutter body, thereby effectively preventing the cutter body from deviating during welding, ensuring the stability and accuracy of the welding process, and ensuring a firm connection between the cutter body and the cutter disc. 4. The present invention realizes a multifunctional integrated design by providing an annular buffer component. On the one hand, during the falling process of the knife body, it can effectively absorb its falling impact force and play a buffering role, thereby avoiding damage to the blade caused by the knife body directly colliding with the knife disc and protecting the integrity of the knife body. On the other hand, when the knife body falls to the surface of the knife disc for welding, the component can also play a pressure positioning function to fix the knife body on the knife disc to prevent it from being displaced by external force during the welding process, thereby ensuring the accuracy and stability of the welding and effectively avoiding the problem of loose installation of the knife body caused by welding deviation.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0029] like Figure 1-11 As shown, the present invention provides an assembly device for a shield machine cutter, comprising an assembly seat 1, a fixture 101, a cutter head 102, a cutter body 104, a loading frame 2, a driving assembly 3, a loading and blanking assembly 4, an annular buffer assembly 5 and an annular welding assembly 6; The assembly seat 1 clamps the cutter disc 102 through the clamp 101, and the loading frame 2 is located above the cutter disc 102 and is driven by the driving assembly 3 to move up and down. The driving assembly 3 includes a driving part 35 that drives the loading frame 2 to rotate. The loading and blanking assembly 4 is arranged in the loading frame 2 and is used to load the cutter body 104 and make it fall onto the cutter disc 102. The loading frame 2 is installed with an electric slide rail 21 that drives the loading and blanking assembly 4 to move horizontally. The annular buffer assembly 5 is installed at the bottom of the loading and blanking assembly 4 to buffer the falling knife body 104 and make the buffered knife body 104 fall onto the knife disc 102; The annular welding assembly 6 is installed at the bottom of the annular buffer assembly 5 to weld the knife body 104 that falls onto the knife disc 102 .

[0030] The present invention fixes the cutter disc 102 on the assembly seat 1 through the clamp 101, and the driving component 3 works to drive the loading frame 2 to move up and down. At the same time, the driving part 35 drives the loading frame 2 to rotate and adjust its position. The loading and blanking component 4 is in the loading frame 2 and is driven by the electric slide rail 21 to move horizontally to a specified position above the cutter disc 102, and the loaded cutter body 104 falls onto the cutter disc 102. The annular buffer component 5 buffers the falling cutter body 104 to reduce the impact force. Then the cutter body 104 falls onto the cutter disc 102, and the annular welding component 6 welds and fixes the cutter body 104 that has fallen on the cutter disc 102.

[0031] like Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, the loading and blanking assembly 4 includes a loading block 41, a loading cylinder 42, a blanking control component 43 and a driver 44. The loading cylinder 42 is rotatably installed in the middle of the loading block 41. The loading cylinder 42 is driven to rotate by the driver 44. The tool body 104 is arranged in the loading cylinder 42. The blanking control component 43 controls the falling of the tool body 104.

[0032] The driver 44 drives the loading cylinder 42 to rotate on the loading block 41, and the tool body 104 is placed in the loading cylinder 42. The drop control component 43 controls the drop of the tool body 104 according to demand. By controlling the rotation of the loading cylinder 42, the angle and position of the tool body 104 in the loading cylinder 42 can be adjusted to facilitate subsequent dropping operations.

[0033] like Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, in this embodiment, the material dropping control component 43 includes a first motor 431, a fan-shaped block 432 and abutment rod 433. Openings 421 are provided on both sides of the loading cylinder 42. The two first motors 431 are respectively installed on both sides of the loading cylinder 42. The output ends of the two first motors 431 are connected to fan-shaped blocks 432. The two fan-shaped blocks 432 correspond to the two openings 421 respectively. The two fan-shaped blocks 432 are connected to abutment rods 433. The two abutment rods 433 pass through the two openings 421 respectively and abut against the bottom of the knife body 104. A falling channel is formed between the two abutment rods 433.

[0034] The first motor 431 is started, driving the sector block 432 to rotate, and the abutting rod 433 on the sector block 432 rotates accordingly. When the two abutting rods 433 move away from each other, the falling channel is opened, and the knife body 104 falls under the action of gravity. At the same time, the sector block 432 rotates into the loading cylinder 42 and abuts against the upper knife body 104. Figure 8As shown, it is prevented from falling prematurely. After the lower knife body 104 falls, the fan-shaped block 432 is driven to return to its original position by the first motor 431, and the upper knife body 104 enters the falling channel. This design ensures that only one knife body 104 falls at a time, avoiding installation confusion caused by multiple knife bodies 104 falling at the same time, and improving the accuracy and stability of installation.

[0035] like Figure 4 As shown, in this embodiment, the driver 44 includes a gear ring 441, a gear 442 and a second motor 443. The gear ring 441 is fixedly mounted on the top of the loading cylinder 42, the gear 442 is meshed with the gear ring 441, the second motor 443 is installed on the loading block 41, and the output end of the second motor 443 is connected to the gear 442.

[0036] The second motor 443 is started, driving the gear 442 to rotate, and the gear 442 engages with the gear ring 441, thereby driving the loading cylinder 42 to rotate. By controlling the forward and reverse rotation and speed of the second motor 443, the loading cylinder 42 can be rotated at different angles and speeds, ensuring that the position of the knife body 104 in the loading cylinder 42 is accurately adjusted, ensuring the accuracy of the falling position of the knife body 104.

[0037] like Figure 5 As shown, in this embodiment, the annular buffer assembly 5 includes a first ring body 51, an elastic member 52 and a rod-type magnetic limit member 53. The first ring body 51 is installed at the bottom of the loading cylinder 42 through the elastic member 52. A plurality of circumferentially arranged rod-type magnetic limit members 53 are installed on the first ring body 51, and the rod-type magnetic limit members 53 extend into the first ring body 51.

[0038] When the knife body 104 falls, it impacts the first ring body 51, and the elastic member 52 is deformed to absorb the impact force. At the same time, the rod-type magnetic limit member 53 supports the knife body 104 to prevent it from directly impacting the knife disc 102. When the knife body 104 needs to fall to the knife disc 102, the electromagnet 535 is energized to generate magnetic attraction, so that the magnetic block 533 approaches the electromagnet 535, and drives the limit rod 532 to enter the fixed tube 531, thereby releasing the load on the knife body 104. This design effectively buffers the impact force of the knife body 104 falling, protects the knife body 104 and the knife disc 102, and uses magnetism to control the fall of the knife body 104, thereby improving the accuracy and reliability of control.

[0039] like Figure 5As shown, in this embodiment, the elastic member 52 includes a first mounting block 521, a second mounting block 522, a guide rod 523 and a tension spring 524. Two first mounting blocks 521 are symmetrically installed on the first ring body 51, and two second mounting blocks 522 are symmetrically installed on the loading cylinder 42. Guide rods 523 are installed on the two first mounting blocks 521, and the two guide rods 523 slide through the two second mounting blocks 522 respectively. A tension spring 524 is sleeved on the guide rod 523, and the two ends of the tension spring 524 are respectively connected to the first mounting block 521 and the second mounting block 522.

[0040] When the knife body 104 impacts the first ring body 51, the tension spring 524 between the first mounting block 521 on the first ring body 51 and the second mounting block 522 on the loading cylinder 42 is stretched, and the guide rod 523 slides in the second mounting block 522 to limit the deformation direction of the tension spring 524, so that the elastic member 52 can stably buffer the impact force of the falling knife body 104, ensure that the buffering process of the elastic member 52 is stable and reliable, enhance the buffering effect, and extend the service life of the elastic member 52.

[0041] like Fig.10 As shown, in this embodiment, the rod-type magnetic limiter 53 includes a fixed tube 531 and an electromagnet 535. A plurality of circumferentially arranged fixed tubes 531 are installed on the first ring body 51. One end of the fixed tube 531 is slidably connected with a limit rod 532 extending into the first ring body 51. One end of the limit rod 532 is installed with a magnetic block 533 located in the fixed tube 531. A spring 534 is sleeved on the limit rod 532, and the two ends of the spring 534 are respectively connected to the magnetic block 533 and the inner wall of one end of the fixed tube 531. The electromagnet 535 is arranged at the other end of the fixed tube 531.

[0042] When the knife body 104 falls, the limit rod 532 is squeezed, so that the magnet 533 compresses the spring 534, and the limit rod 532 moves into the fixed tube 531, which plays a bearing and buffering role for the knife body 104. When the electromagnet 535 is energized, the electromagnet 535 generates a magnetic suction force to attract the magnet 533, driving the limit rod 532 to further enter the fixed tube 531, thereby releasing the bearing on the knife body 104. When the power is off, the elastic force of the spring 534 resets the magnet 533 and the limit rod 532.

[0043] like Figure 5 ,and Fig. 9 As shown, in this embodiment, the annular welding assembly 6 includes a second ring body 61, an electric annular guide rail 62 and a welding gun component 63. The second ring body 61 is installed at the other end of a plurality of fixed tubes 531, the electric annular guide rail 62 is installed at the bottom of the second ring body 61, and the driving end of the electric annular guide rail 62 is installed with a welding gun component 63.

[0044] The electric annular guide rail 62 is started, driving the welding gun component 63 to move on the annular track at the bottom of the second ring body 61 . During the movement, the welding gun component 63 welds the knife body 104 that falls on the knife disc 102 , so that the knife body 104 is firmly connected to the knife disc 102 .

[0045] like Fig. 9 As shown, in this embodiment, the welding gun component 63 includes an assembly block 631 and a welding gun head 632. The assembly block 631 is installed at the driving end of the electric annular guide rail 62. A socket is opened in the assembly block 631, and the welding gun head 632 is inserted into the socket.

[0046] During operation, when the electric annular guide rail 62 drives the assembly block 631 to move, the welding gun head 632 moves accordingly to perform welding operations. When the welding gun head 632 needs to be replaced, it can be directly pulled out from the socket for replacement.

[0047] like Figure 1 and Fig.11 As shown, in this embodiment, the driving assembly 3 also includes a cylinder 31, a screw 32, a sleeve block 33 and a nut 34. Two fixing blocks 103 are symmetrically installed on the assembly seat 1. The two cylinders 31 are respectively installed on the two fixing blocks 103. The driving ends of the two cylinders 31 are connected to the screw 32. The two screws 32 are sleeved with a sleeve block 33. Two nuts 34 are threadedly sleeved on the screw 32. The sleeve block 33 is arranged between the two nuts 34. The driving part 35 is installed between the two sleeve blocks 33. The driving part 35 includes a shaft column 351, a third motor 352, a turntable 353, an assembly rod 354 and an assembly ring body 355. The shaft column 351 is installed between the two sleeve blocks 33, the third motor 352 is installed on the shaft column 351, and the output end of the third motor 352 is connected to the turntable 353 located below the shaft column 351. A plurality of circumferentially arranged and downwardly inclined assembly rods 354 are installed on the turntable 353. The assembly ring body 355 is installed at the bottom ends of the plurality of assembly rods 354, and the loading frame 2 is installed in the middle of the assembly ring body 355.

[0048] The cylinder 31 is started to drive the screw rod 32 to extend and retract, and the sleeve block 33 moves on the screw rod 32. The position of the sleeve block 33 is fixed by the nut 34. The third motor 352 is started to drive the turntable 353 to rotate, and the assembly rod 354 and the assembly ring body 355 on the turntable 353 rotate accordingly, thereby driving the loading frame 2 to rotate. By controlling the cylinder 31 and the third motor 352, the up and down movement and rotation of the loading frame 2 can be realized. This structure provides stable up and down movement and rotation power for the loading frame 2, facilitates the adjustment of the position of the loading frame 2, and meets the installation requirements of different tool discs 102 and tool bodies 104.

[0049] The specific working principle of the present invention is as follows: First, the cutter disc 102 is fixed on the assembly seat 1 by the clamp 101, and the cutter body 104 is placed in the loading cylinder 42 of the loading blanking assembly 4. The second motor 443 in the driver 44 drives the gear 442, drives the gear ring 441 to rotate the loading cylinder 42, adjusts the position of the cutter body 104, and the driving assembly 3 works. The cylinder 31 drives the screw rod 32, so that the sleeve block 33 drives the driving part 35 to move up and down. At the same time, the third motor 352 drives the turntable 353, drives the loading frame 2 to rotate through the assembly rod 354 and the assembly ring body 355, adjusts the position and height of the loading frame 2, and the electric slide rail 21 on the loading frame 2 drives the loading blanking assembly 4 to move horizontally to the specified position above the cutter disc 102. The first motor 431 in the blanking control component 43 drives the fan-shaped block 432 to rotate, so that the abutment rods 433 are separated from each other, the falling channel is opened, and the cutter body 104 falls. When the knife body 104 falls, it first falls into the first ring body 51 of the annular buffer assembly 5, the tension spring 524 of the elastic member 52 is stretched, the guide rod 523 slides, and buffering is performed. The limiting rod 532 of the rod-type magnetic limiting member 53 carries the knife body 104 to prevent it from directly impacting the knife disc 102. When the knife body 104 completes buffering, the electromagnet 535 is energized to attract the magnetic block 533, driving the limiting rod 532 to enter the fixed tube 531, and the knife body 104 falls steadily to the installation position on the surface of the knife disc 102; After the tool body 104 falls onto the surface of the tool disc 102, the annular welding assembly 6 starts working, and the electric annular guide rail 62 drives the welding gun component 63 to weld and fix the tool body 104. During welding, the power is turned off to make the electromagnet 535 lose its magnetism, and the spring 534 resets the limit rod 532. The driving assembly 3 drives the loading frame 2 and the loading and blanking assembly 4 to move downward, and the limit rod 532 presses on the tool body 104 to prevent the tool body 104 from moving during welding.
