When in use, the position of the unloading mechanism 8 can be changed by sliding the third fixed bracket 705 and cooperating with the rotation of the second threaded rod 707, and the unloading mechanism 8 is moved to the specified position for unloading.

[0055] like Fig.11 As shown, the unloading mechanism 8 includes a cylindrical barrel 801, on which a long rotating rod 802 is rotatably provided, and a first pulley 803 is fixedly provided on the long rotating rod 802 at the top of the cylindrical barrel 801, and the first pulley 803 rotates coaxially with the long rotating rod 802, and a second pulley 804 is rotatably provided at the top of the cylindrical barrel 801, and the first pulley 803 and the second pulley 804 are connected by a belt 805, and the second pulley 804 is also connected to a fourth motor 806, and the fourth motor 806 is fixedly connected to the top of the cylindrical barrel 801, and a detachably connected top cover is provided at the top of the cylindrical barrel 801, and the first pulley 803 and the second pulley 804 are both arranged on the top cover, and the long rotating rod 802 is rotatably connected to the top cover.

[0056] like Fig.11 As shown, the long rotating rod 802 passes through the cylindrical tube 801 and is fixedly connected to the first disc 807 and the second disc 815 respectively. A third disc 810 is provided between the first disc 807 and the second disc 815. The third disc 810 is rotatably connected to the long rotating rod 802. The first disc 807 is also provided with a plurality of second through grooves 808. The third disc 810 is fixedly provided with a plurality of connecting members 813. The plurality of connecting members 813 pass through the second through grooves 808 and are fixedly connected to the cylindrical tube 801. The first disc 807 is also provided with a plurality of first waist-shaped grooves 809. The first waist-shaped grooves 809 are slidably provided with a first cylindrical block 812. A first thin plate 811 is fixedly provided at the bottom end of the first cylindrical block 812. The first thin plate 811 is slidably connected to the third disc 810. Fig.12As shown, a plurality of second waist-shaped grooves 816 are formed on the second disc 815 , a second cylindrical block 817 is slidably provided on the second waist-shaped grooves 816 , a second thin plate 814 is fixedly provided on the top of the second cylindrical block 817 , and the second thin plate 814 is slidably connected to the third disc 810 .

[0057] When in use, the fourth motor 806 drives the long rotating rod 802 to rotate. When the long rotating rod 802 rotates, the first disc 807 and the second disc 815 fixedly connected thereto will also rotate synchronously. Since the first disc 807 and the second disc 815 are respectively provided with the first waist-shaped groove 809 and the second waist-shaped groove 816, the first thin plate 811 and the second thin plate 814 will be driven to slide during the rotation of the first waist-shaped groove 809 and the second waist-shaped groove 816. Since the bending directions of the first waist-shaped groove 809 and the second waist-shaped groove 816 are opposite, when the first thin plate 811 slides toward the center of the third disc 810, the second thin plate 814 slides toward the outside of the third disc 810, and the sliding directions of the first thin plate 811 and the second thin plate 814 always remain opposite.

[0058] When the second thin plate 814 slides out of the third disc 810, the first thin plate 811 is located inside the third disc 810, and a floating oil seal 108 or an O-ring 109 is arranged outside the cylindrical tube 801. At the beginning, ensure that the second thin plate 814 slides out of the third disc 810 to provide a blocking and supporting effect for the floating oil seal 108 or the O-ring 109 to prevent it from falling directly. Then, after the unloading mechanism 8 is moved to the specified position, the long rotating rod 802 is rotated to retract the second thin plate 814. At the same time, the first thin plate 811 slides out of the third disc 810, and the distance between the first thin plate 811 and the second thin plate 814 is equal to the thickness of the floating oil seal 108 or the O-ring 109. In this way, it can be ensured that the first thin plate 811 is positioned below the second to last floating oil seal 108 or the O-ring 109 when sliding out, that is, the last floating oil seal 108 or the O-ring 109 will fall from the cylindrical tube 801, which is convenient for the one-by-one unloading of the floating oil seals 108 or the O-rings 109.

[0059] A method for assembling a shield machine cutter assembly device comprises the following steps:

[0060] S1: Figure 5-7 As shown, first, the knife shaft 101 is placed on the support plate 514 in the feeding trough 503, and the first motor is started to realize the lifting of the support plate 514, and at the same time, the movement of the two second clamping plates 510 is realized, and the support plate 514 lifts the knife shaft 101 to a certain height, and the knife shaft 101 passes through the first through groove 511, and the two second clamping plates 510 clamp the bottom of the knife shaft 101 to ensure that most of the knife shaft 101 is located above the platform plate 501, and the knife shaft 101 is also fixed from the bottom to facilitate subsequent assembly;

[0061] S2: The placement platform 6 is used to place various parts of the shield machine, including the lower end cover 102, the lower bearing 103, the bearing spacer 104, the assembled cutter hub 105, the upper bearing 107 and the upper end cover 110. The middle positions of the above parts are provided with round holes, which are respectively mounted on a number of cylindrical rods 606 when in use. In this embodiment, the number of cylindrical rods 606 is set to six, which is convenient for placing the above parts. Each cylindrical rod 606 can be mounted with multiple parts. The parts will compress the first spring 605 downward under the action of their own gravity, and the round baffle 607 will provide a support for the bottommost parts;

[0062] The installation method of the above-mentioned parts is as follows: when the parts are assembled to the knife shaft 101 in sequence, first, the third gear 623 is driven to rotate by the second motor, and the third gear 623 is meshed with the gear ring 604 for transmission, so as to realize the cylindrical rod 606 and the circular baffle 607 on the gear ring 604, and the parts to be installed are rotated to a position facing the assembly platform 5 according to the installation sequence, and then the pressure rod 615 is pressed downward, and the rectangular lifting plate 620 is moved upward by the meshing transmission between the second gear 617, the second rack 616 and the third rack 619. During the upward movement of the rectangular lifting plate 620, it gradually contacts the circular baffle 607 and gives the circular baffle 607 an upward force, so that the circular baffle 607 starts to move upward, while the cylindrical rod 606 remains stationary until the uppermost part is located at the top of the cylindrical rod 606 for easy removal;

[0063] Then, the picking mechanism 3 is controlled to realize the two first clamping plates 308 to clamp the uppermost component through the cooperation of the first telescopic cylinder 302, the second telescopic cylinder 304 and the two-way telescopic cylinder 307, and the component is inserted into the knife shaft 101;

[0064] S3: During the installation process, the assembly of the floating oil seal 108 and the O-ring 109 still needs manual cooperation. During use, the floating oil seal 108 and the O-ring 109 can be respectively inserted into the unloading mechanism 8 on both sides, and the floating oil seal 108 and the O-ring 109 can be unloaded by rotating the long rotating rod 802. During use, the unloading mechanism 8 can be moved to the knife shaft 101, and the floating oil seal 108 and the O-ring 109 are released one by one. The installation position of the floating oil seal 108 and the O-ring 109 is manually adjusted and installed on the designated parts;

[0065] S4: After the assembly is completed, pull the oil pipe 403 and insert its upper oil nozzle 405 into the oil hole of the upper end cover 110, start the oil pump in the oil tank 401 to inject lubricating oil into the oil hole, and finally install the oil plug 111 on the oil hole to finally complete the assembly of the shield machine tool.
