[0002] Coking refers to the process of heating coking coal to about 1000℃ (high-temperature dry distillation) in an air-tight condition to produce coke, coke oven gas and other coking chemical products through thermal decomposition and coking.

[0003] During coking, the sealing of the coke oven door is very important in order to isolate the air and prevent the leakage of coking gas products. The coke oven adopts a sealing groove on the door frame and a sealing strip on the oven door that cooperates with the sealing groove to ensure the sealing of the coke oven.

[0004] When the door frame of the coking oven is produced, the sealing groove is processed by milling. During processing, the door frame is fixed on the workbench by a clamp, and then the milling cutter is driven by a robotic arm to mill the door frame to process the sealing groove.

[0005] During the processing of the sealing groove, the door frame is easily deformed along the width direction of the sealing groove due to the thin wall and poor rigidity of the door frame, which ultimately affects the processing accuracy of the sealing groove. Summary of the invention

[0043] The following is combined with Figure 1-7 This application is described in further detail.

[0044] The present application embodiment discloses a coke oven door frame sealing groove processing device. Figure 1 and Figure 2 A coke oven door frame sealing groove processing device comprises a workbench 2, a processing assembly 3, an outer wall fixing assembly 4 and an inner wall fixing assembly 5.

The processing assembly 3 is arranged on the workbench 2, and is used to process a sealing groove on the door frame 1. The outer wall fixing assembly 4 is arranged on the workbench 2, and is used to fix the outer side wall of the door frame 1. The inner wall fixing assembly 5 is arranged on the workbench 2, and is used to fix the inner side wall of the door frame 1.

[0045] When processing the door frame 1, the operator places the door frame 1 on the workbench 2 through the lifting equipment, and then fixes the door frame 1 through the outer wall fixing component 4 while supporting the outer wall of the door frame 1, and then supports the inner wall of the door frame 1 through the inner wall fixing component 5, and finally processes the sealing groove on the door frame 1 through the processing component 3.

[0046] Reference Figure 1 and Figure 2The processing assembly 3 includes a mechanical arm 31, a motor 33 and a milling cutter 32. The mechanical arm 31 is at least a mechanical arm 31 that can move in the three coordinate axis directions of X, Y and Z. In this embodiment, a six-axis mechanical arm 31 is used. The base of the mechanical arm 31 is arranged above the workbench 2 and is fixedly connected to the workbench 2. The motor 33 is fixedly arranged on the mechanical arm 31. The milling cutter 32 is coaxially fixedly connected with the output shaft of the motor 33.

[0047] When the door frame 1 is processed, the motor 33 drives the milling cutter 32 to rotate, and the feeding and movement of the milling cutter 32 are controlled by the mechanical arm 31 , so that the sealing groove is processed on the door frame 1 .

[0048] Reference Figure 1 The outer wall fixing assembly 4 is provided with four groups, and corresponds to the four outer walls of the door frame 1 one by one. The outer wall fixing assembly 4 includes a fixing rod 41 and a first hydraulic cylinder 42. The fixing rod 41 is horizontally arranged on the top of the workbench 2, and the four fixing rods 41 form a rectangular structure.

[0049] Reference Figure 3 and Figure 4 , two first T-blocks 412 are fixedly arranged at one end of the fixing rod 41. Two first T-slots 411 are provided along the length direction of the fixing rod 41 on one side of the fixing rod 41 close to the door frame 1. The first T-blocks 412 on the fixing rod 41 correspond to the first T-slots 411 on the adjacent fixing rods 41 one by one, and the first T-blocks 412 on the fixing rod 41 are slidably arranged in the first T-slots 411 on the adjacent fixing rods 41, and the sliding axis is arranged along the length direction of the fixing rod 41 where the first T-slots 411 are located.

[0050] Reference Figure 2 and Figure 4 A second T-shaped slot 413 is provided on the side of the fixed rod 41 away from the door frame 1 along the length direction of the fixed rod 41. The first hydraulic cylinder 42 is located on the side of the fixed rod 41 away from the door frame 1, the fixed end of the first hydraulic cylinder 42 is fixedly connected to the workbench 2, and a second T-shaped block 421 is fixedly provided on the movable end of the first hydraulic cylinder 42. The second T-shaped block 421 is located in the second T-shaped slot 413 and is slidably connected to the fixed rod 41, and the sliding axis is provided along the length direction of the fixed rod 41.

[0051] When processing the door frame 1, the operator places the door frame 1 on the workbench 2, and then controls the four first hydraulic cylinders 42 to jointly drive the fixing rods 41 to slide toward the center of the four fixing rods 41, thereby clamping and fixing the door frame 1 at the center of the four fixing rods 41. During the processing of the door frame 1, the fixing rods 41 abut against the outer wall of the door frame 1, thereby supporting the outer wall of the door frame 1 and preventing the outer wall of the door frame 1 from being deformed during processing.

[0052] Reference Figure 2 and Figure 3 There are four groups of inner wall fixing components 5 , which correspond one by one to the four inner walls of the door frame 1 .

[0053] Reference Figure 2 and Figure 5 The inner wall fixing assembly 5 includes a mounting block 53, a fixing block 51, a spring 54 and a second hydraulic cylinder 52. The mounting block 53 is slidably arranged in a groove on the workbench 2, and the sliding axis is arranged in a direction perpendicular to the inner wall of the door frame 1. A mounting groove 531 is provided at the top of the mounting block 53. The fixing block 51 is slidably arranged in the mounting groove 531, and the sliding axis is arranged in a vertical direction, and the top of the fixing block 51 is a trapezoidal structure. Two springs 54 are provided, and the spring 54 is vertically arranged in the mounting groove 531. The two ends of the spring 54 are fixedly connected to the fixing block 51 and the mounting block 53 respectively. The elastic force of the spring 54 is greater than the gravity of the fixing block 51 and less than the gravity of the door frame 1. The second hydraulic cylinder 52 is horizontally arranged in a groove on the workbench 2, the fixed end of the second hydraulic cylinder 52 is fixedly connected to the workbench 2, and the movable end of the second hydraulic cylinder 52 is fixedly connected to the mounting block 53.

[0054] Reference Figure 3 and Figure 6 The workbench 2 is provided with inner corner fixing components 6, and there are four sets of inner corner fixing components 6, which correspond to the four inner corners of the door frame 1 one by one. The inner corner fixing components 6 include a special-shaped block 61, a slide bar 62 and a clamping block 63.

[0055] Reference Figure 6 and Figure 7 Four special-shaped blocks 61 are horizontally arranged at the four inner corners of the door frame 1. The two side walls of the special-shaped block 61 are matched with the inclined surfaces of the two adjacent fixed blocks 51, and the two side walls of the special-shaped block 61 are respectively in contact with the inclined surfaces of the two adjacent fixed blocks 51. A slide groove 511 is provided on the two inclined surfaces of the fixed block 51. Two slide bars 62 are provided, and correspond to the slide grooves 511 one by one. The two slide bars 62 are fixedly arranged on the special-shaped block 61. The slide bars 62 are used in conjunction with the slide grooves 511. The slide bars 62 are slidably connected with the fixed block 51 along the length direction of the slide bars 62. The clamping block 63 is fixedly arranged at the bottom of the special-shaped block 61.

[0056] When processing the door frame 1, the operator first drives the mounting block 53 to drive the fixing block 51 to move to a suitable position through the second hydraulic cylinder 52, and then places the door frame 1 on the workbench 2. At this time, the bottom of the door frame 1 abuts against the clamping block 63, and then the door frame 1 is clamped and fixed by the outer wall fixing component 4, and then the mounting block 53 is driven by the second hydraulic cylinder 52 to slide in the direction close to the door frame 1, thereby driving the fixing block 51 to slide and abut against the inner wall of the door frame 1, supporting the inner wall of the door frame 1, and preventing the inner wall of the door frame 1 from being deformed during processing. When the mounting block 53 drives the fixing block 51 to slide in the direction of the door frame 1, relative sliding occurs between the fixing block 51 and the special-shaped block 61, so that the special-shaped block 61 slides upward relative to the fixing block 51. When the fixing block 51 abuts against the inner wall of the door frame 1, the special-shaped block 61 abuts against the inner corner of the door frame 1, supporting the inner corner of the door frame 1, and preventing the inner corner of the door frame 1 from being deformed during processing.

[0057] When the size of the door frame 1 to be processed changes, the operator uses the second hydraulic cylinder 52 to adjust the initial positions of the mounting block 53 and the fixing block 51, so that the mounting block 53 and the fixing block 51 slide toward or away from the fixing rod 41. At this time, under the action of the spring 54, the fixing block 51 and the special-shaped block 61 are at a higher height in the vertical direction. When the door frame 1 to be processed is placed on the workbench 2 and abuts against the clamping block 63, under the action of the gravity of the door frame 1, the clamping block 63 drives the special-shaped block 61 to slide downward, so that the fixing block 51 compresses the spring 54 and slides into the mounting groove 531 until the door frame 1 is placed on the workbench 2. After the outer wall fixing assembly 4 clamps and fixes the door frame 1, the operator drives the mounting block 53 to slide toward the door frame 1 through the second hydraulic cylinder 52. At this time, the height of the special-shaped block 61 remains unchanged, and the fixing block 51 slides upward until the side wall of the fixing block 51 abuts against the inner wall of the door frame 1. At this time, on the same horizontal plane as the door frame 1, the sum of the lengths of the fixing block 51 and the two adjacent special-shaped blocks 61 is the same as the length of the inner wall of the door frame 1.

[0058] Reference Figure 1 and Figure 2 A cutting fluid assembly 7 is provided on the workbench 2, and the cutting fluid assembly 7 includes a liquid reservoir 71, a nozzle 72, a connecting pipe 73 and a water pump 74. The liquid reservoir 71 is fixedly provided on the workbench 2, and cutting fluid is preset inside the liquid reservoir 71. The nozzle 72 is fixedly provided on the robot arm 31 and is located on one side of the milling cutter 32, and the outlet of the nozzle 72 is arranged toward the bottom of the milling cutter 32. Both ends of the connecting pipe 73 are respectively connected to the inside of the liquid reservoir 71 and the nozzle 72. The water pump 74 is fixedly installed on the connecting pipe 73, and the water pump 74 is used to transport the cutting fluid in the liquid reservoir 71 to the nozzle 72.

[0059] During the processing of the door frame 1, the water pump 74 is in operation, transporting the cutting fluid in the liquid storage tank 71 to the nozzle 72, spraying it onto the milling cutter 32 and the door frame 1, so as to cool and lubricate the milling action.

[0060] The implementation principle of a coke oven door frame sealing groove processing device in the embodiment of the present application is:

[0061] When processing the door frame 1, the operator first drives the mounting block 53 to move the fixed block 51 to a suitable position through the second hydraulic cylinder 52 according to the size of the door frame 1 to be processed, and then places the door frame 1 on the workbench 2. The door frame 1 abuts against the clamping block 63. Under the gravity of the door frame 1, the clamping block 63 drives the special-shaped block 61 to slide downward, so that the fixed block 51 compresses the spring 54 and slides into the mounting groove 531 until the door frame 1 is placed on the workbench 2. Then the operator controls the four first hydraulic cylinders 42 to jointly drive the fixed rod 41 to slide toward the center position of the four fixed rods 41, so that the door frame 1 is clamped and fixed at the center of the four fixed rods 41. Finally, the operator drives the mounting block 53 to slide in the direction close to the door frame 1 through the second hydraulic cylinder 52. At this time, the height of the special-shaped block 61 remains unchanged, and the fixed block 51 slides upward until the side wall of the fixed block 51 abuts against the inner wall of the door frame 1.

[0062] When the door frame 1 is processed, the motor 33 drives the milling cutter 32 to rotate, and the feeding and movement of the milling cutter 32 are controlled by the mechanical arm 31 , so that the sealing groove is processed on the door frame 1 .

[0063] During the processing of the door frame 1, the water pump 74 is in operation, transporting the cutting fluid in the liquid storage tank 71 to the nozzle 72, spraying it onto the milling cutter 32 and the door frame 1, so as to cool and lubricate the milling action.

[0064] During the processing of the door frame 1, the fixing rod 41 abuts against the outer wall of the door frame 1, thereby supporting the outer wall of the door frame 1 and preventing the outer wall of the door frame 1 from being deformed during processing. The fixing block 51 abuts against the inner wall of the door frame 1, thereby supporting the inner wall of the door frame 1 and preventing the inner wall of the door frame 1 from being deformed during processing. The special-shaped block 61 abuts against the inner corner of the door frame 1, thereby supporting the inner corner of the door frame 1 and preventing the inner corner of the door frame 1 from being deformed during processing.

[0065] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
