Description

Technical Field

[0001] The invention relates to the technical field of cutter disc production, and in particular to a clamping and positioning device for producing a shield machine cutter disc. Background Art

[0002] A shield machine is a tunnel boring machine that uses the shield method. A cutterhead is installed at the front of the shield machine. Its main function is to cut boulders, rocks and concrete, and help the shield machine drill into the tunnel smoothly. The shield machine cutterhead usually includes a center disc and multiple side blocks in the circumferential direction of the center disc, as well as a subbeam connecting adjacent side blocks. Due to the large size of the shield machine cutterhead, the center disc and multiple side blocks need to be assembled by welding during the production process. Before welding and assembly, the center disc and side blocks need to be positioned to ensure the quality requirements of the welding.

[0003] Traditionally, when welding and assembling the center disk and the side blocks, the center disk is usually first simply pressed and positioned on a workbench, and then multiple side blocks are placed at the ends corresponding to the center disk for abutment and fit. The above operation requires that abutment devices that can bring the side blocks and the center disk into contact be provided on the workbench at each side block. This not only increases the process requirements for shield machine cutter head processing, but also affects the production efficiency of the enterprise. Summary of the invention

Through holes for installing an electric cylinder 325 are provided on the turntable 211 and the workbench 1, and the movable end of the electric cylinder 325 is fixedly connected to the bottom surface of the slide rod 323.

[0043] The working principle of the clamping assembly 3 is to sleeve the center disk 9 on the cylinder 212, control the electric cylinder 325 to contract, drive the lifting body 311 to slide downward, and under the action of multiple hinged swing arms 314, drive multiple abutment seats 316 to move inward to effectively clamp the outer wall of the center disk 9. At the same time, in the process of the lifting body 311 sliding downward, through the cooperation of the inclined surface on its upper part and the abutment rod 321, drive the multiple abutment rods 321 to slide outward, so that the outer walls of the multiple abutment rods 321 are tightly abutted against the inner wall of the center disk 9, so that the outer wall and the inner wall of the center disk 9 can be synchronously positioned, thereby improving the stability of the center disk 9 after positioning.

[0044] Combined with Figure 7 and attached Figure 8 As shown, the lifting assembly 4 includes a lifting seat 411 that is slidably arranged up and down in the workbench 1, and a material holding assembly 6 is placed on the top surface of the lifting seat 411. Guide rods 412 that slide with the bottom surface of the workbench 1 are fixedly provided at the four corners of the bottom surface of the lifting seat 411. A sliding seat 413 is commonly provided at the bottom ends of the four guide rods 412. A fixed seat 414 is provided on the ground corresponding to the center position of the sliding seat 413. An adjusting screw 415 that rotates together with the fixing seat 414 and the bottom surface of the workbench 1 and that threads on the sliding seat 413 are provided.

[0045] The working principle of the lifting assembly 4 is to control the rotation of the adjusting screw rod 415, and under the action of the thread, drive the sliding seat 413 to slide upward, drive the four guide rods 412 to slide upward, and then drive the lifting seat 411 and the material holding assembly 6 to slide upward.

[0046] Combined with Figure 8 , Attachment Fig. 9 , Attachment Fig.10 and attached Fig.11As shown, a lifting screw rod 521 is fixedly arranged on the bottom surface of the limiting rod 414, and a threaded barrel 522 which is threadably matched with the lifting screw rod 521 is rotatably arranged on the workbench 1, and a gear 1 523 is arranged at the end of the threaded barrel 522 extending out of the bottom surface of the workbench 1, and a rotating shaft 1 is passed through the workbench 1 between the gear 1 523 and the adjusting screw rod 415, and a gear 2 524 which is meshed with the gear 1 523 is arranged on the rotating shaft 1, and the end of the rotating shaft top surface is connected to the output shaft of the motor 2 525, and the motor 2 525 is started to drive the gear 2 524 to rotate, and then drive the gear 1 523 and the threaded barrel 522 to rotate, and under the action of the thread force, the lifting screw rod 521 is driven to slide downward, and at the same time, the limiting rod 4 514 is driven to slide downward, so that it can ensure that the welded edge block 10 rotates with the center disk 9 without obstruction;

[0047] A spline shaft 416 that is rotatably matched with the workbench 1 is fixed on the top surface of the adjusting screw rod 415, and a gear 3 417 that is matched with the gear 2 524 is slidably sleeved on the spline shaft 416. A connecting component 8 is provided between the gear 3 417 and the lifting screw rod 521. When the lifting screw rod 521 slides up and down, the connecting component 8 is used to separate or mesh the gear 3 417 and the gear 2 524;

[0048] An extension portion 418 is provided on the gear three 417, and the cutting assembly 8 includes an adjusting seat 811 rotatably arranged on the extension portion 418, an external thread 812 is also provided on the extension portion 418, and a slotted nut 813 matching therewith is provided on the external thread 812, an upwardly extending cavity is provided on the bottom surface of the lifting screw rod 521, and an electric push rod 1 814 is provided in the cavity, a connecting seat 1 815 is provided at the movable end of the electric push rod 1 814, a slide groove 1 816 is provided on the connecting seat 1 815, and a slider 1 817 is slidably provided on the slide groove 1 816, a connecting seat 2 818 is provided on the adjusting seat 811, a slide groove 2 819 is provided on the connecting seat 2 818, and a slider 2 820 is slidably provided on the slide groove 2 819, a swing rod 821 is hinged between the slider 2 820 and the slider 1 817, and a supporting seat 2 822 hinged to the swing rod 821 is fixedly provided on the bottom surface of the workbench 1.

[0049] The working principle of the continuous cutting assembly 8 is that when the lifting screw rod 521 slides downward, it drives the electric push rod 1 814 and the connecting seat 1 815 to slide downward, and then drives the connecting end of the hinged swing rod 821 to slide downward, and under the action of the hinge connection with the supporting seat 2 822, drives the other end connected to the swing rod 821 to move upward, and then drives the connecting seat 2 818 and the adjusting seat 811 to move upward, and at the same time drives the gear 3 417 to move upward. When the lifting screw rod 521 and the limit rod 4 514 are lowered, the electric push rod 1 814 is controlled to extend slightly, and the adjusting seat 811 and the gear 3 417 are driven to move upward again through the hinged swing rod 821, so that the gear 3 417 and the gear 2 524 are meshed, so that the power source for the rotation of the adjusting screw rod 415 and the threaded barrel 522 can be concentrated on the same motor 2 525;

[0050] Control the motor 2 525 to rotate in the opposite direction, and control the extension of the electric push rod 1 814 at the same time, so that the ascending movement of the lifting screw 521 can be compensated during the ascending process of the lifting screw 521, ensuring that the positions of the connecting seat 1 815 and the swing rod 821 remain unchanged, so that the gear 3 417 and the gear 2 524 are always in a meshing state, so that the adjusting screw 415 and the threaded barrel 522 are synchronously rotated and adjusted, and then the sliding seat 413 and the lifting screw 521 are synchronously slid upwardly adjusted, thereby reducing the interval time when the lifting and limiting movements are controlled separately;

[0051] When the ends of the center disk 9 are welded with the side blocks 10, first control the limit rod three 513 to slide downward, and then push the component 7 to make the end of the first side block 10 at the top contact with the end of the center disk 9. After the welding is completed, control the limit rod four 514 to slide downward to release the limit of the side block 10 by the limit rod four 514, so that the side block 10 can rotate synchronously with the center disk 9. When the limit rod four 514 slides downward, the jacking component 4 is combined with the power source, and the jacking component 4 and the limit rod four 514 can be driven to slide upward synchronously under the action of the same power source, so that the second side block 10 is combined with the other end of the center disk 9. This reduces the interval time when the jacking and limiting movements are controlled separately, and improves the efficiency of their adjustment.

[0052] Combined with Fig.12As shown, a slewing bearing 213 is provided at one end of the top surface of the workbench 1, and the slewing bearing 213 includes an inner ring 2131 and an outer ring 2132 rotating on the inner ring 2131. The inner ring 2131 is fixedly connected to the workbench 1, and the turntable 211 is fixedly connected to the outer ring 2132. A plurality of mounting holes are respectively provided on the outer ring 2132 and the inner ring 2131 along their circumferential directions. Under the action of the mounting holes, the inner ring 2131 and the outer ring 2132 are fixedly connected by positioning bolts. They are respectively fixedly connected to the workbench 1 and the turntable 211, and gear teeth 2133 are opened on the circumferential direction of the outer ring 2132. An extension seat 112 is provided on the workbench 1 and a rotating shaft 214 is passed through the extension seat 112. A gear 4 215 meshing with the gear teeth 2133 is provided on the top surface of the rotating shaft 214, and a protective cover 113 is provided on the extension seat 112 outside the gear 4 215, and the bottom end of the rotating shaft 214 is connected to the output shaft of the motor 1 216.

[0053] The working principle of controlling the rotation of the turntable 211 is to start the motor 1 216 to drive the gear 4 215 to rotate. Under the action of the engagement between the gear 4 215 and the gear teeth 2133, the outer ring 2132 is driven to perform circular rotation adjustment on the inner ring 2131, and at the same time, the turntable 211 and the cylinder 212 are driven to rotate and adjust.

[0054] Combined with Fig.13 As shown, the limit rod 2 512 and the limit rod 4 514 are both provided with an L-shaped support seat 3 515, and a slidable guide rod 3 516 is passed through the support seat 3 515. The inner end of the guide rod 3 516 is provided with an abutment block 517 that is compatible with the end of the edge block 10, and a return spring 3 518 is also wound around the guide rod 3 516. When the edge block 10 is pushed, the abutment blocks 517 at both ends can be driven to move away from each other through the inclined surface of the edge block 10, and under the action of the abutment blocks 517 at both ends, auxiliary limiting is performed when the edge block 10 is pushed.

[0055] Combined with Fig.14 and attached Fig.15As shown, since the top surface of each edge block 10 is provided with a raised structure, direct stacking cannot be performed when placing the edge blocks 10. In order to ensure the spaced placement requirements of multiple edge blocks 10, a material holding assembly 6 is provided, and the material holding assembly 6 includes a lower placement seat 611 and an upper placement seat 612 respectively arranged at the lower and upper parts, and support columns 614 are provided at the three corners between the upper placement seat 612 and the lower placement seat 611, and multiple middle placement seats 613 are equidistantly provided on the three support columns 614, and the upper placement seat 612, the middle placement seat 613 and the lower placement seat 611 are provided with a hole that can pass through the edge block 10, and the top surface of the upper placement seat 612 and the bottom surface of the lower placement seat 611 are both provided with a detachable upper support plate 616 and a lower support plate 615 in the corresponding installation grooves, and a detachable middle support plate 617 is also provided in the placement groove corresponding to each middle placement seat 613. The detachable connection of the upper support plate 616 and the middle support plate 617 facilitates the pre-lifting and placement of multiple edge blocks 10 from the top, and the detachable connection of the lower support plate 615 enables the material holding assembly 6 to be lifted out after the adjustment and welding of all the edge blocks 10 are completed, so as to facilitate the lifting operation of the center plate 9 and the edge blocks 10 after the welding is completed;

[0056] A swingable stabilizing seat 618 is hinged between the upper placement seat 612 connected without a support column 614 and the middle placement seat 613 adjacent thereto, as well as at the corners of each adjacent middle placement seat 613, and a screw 619 is passed through the end of the stabilizing seat 618 away from the hinge, so as to ensure that the welded side block 10 is not blocked when rotating with the center disk 9. A positioning rod is fixedly provided on the bottom surface of the lower support plate 615, and a positioning hole for inserting the positioning rod is opened on the lifting seat 411, so as to ensure the stability of the material holding assembly 6 placed on the lifting seat 411.

[0057] In the specific implementation of the present invention, the center disk 9 is first sleeved on the cylinder 212, and then the outer wall and the inner wall of the center disk 9 are synchronously clamped and positioned by the clamping assembly 3 to ensure the stability of the center disk 9 after positioning, and then the material holding assembly 6 with the edge block 10 pre-placed is hoisted to the lifting seat 411, and the limit rod 3 513 is controlled to slide downward, and then the pushing assembly 7 is controlled to push the uppermost edge block 10 inward, so that the edge block 10 and the end of the center disk 9 are effectively abutted, and then the contacting portion is welded by an external welding device;

[0058] When the end of a side block 10 and a center disk 9 is welded, the limit rod 514 is controlled to slide downward, and then the screw 619 is removed to make the stabilizing seat 618 in a swingable state, and then the cylinder 212 is controlled to rotate and adjust through the rotating component 2, while driving the center disk 9 and the welded side block 10 to rotate and adjust, and at the same time, the other connecting end of the center disk 9 is rotated to the welding position, and then the jacking component 4 is controlled to move upward so that the side block 10 below it moves upward to a position flush with the end of the center disk 9, and the pushing component 7 is controlled again to push the side block 10 after it moves upward to abut against and position it, so that the center disk 9 and the other end of the side block 10 can be welded, and so on, all the connecting ends of the center disk 9 can be effectively welded to the end of each side block 10 respectively, which not only reduces the process requirements for the shield machine cutter head processing, but also improves the production efficiency of the enterprise.
