[0046] Example 1

[0047] An online automatic welding and grinding device for a coking plant furnace door frame includes a frame 1; a mobile platform 2 is arranged to move relative to the frame 1, and the moving direction of the mobile platform 2 is defined as the z direction; a mobile platform 2 is arranged to move relative to the mobile platform 23, and the moving direction of the mobile platform 23 is perpendicular to the moving direction of the mobile platform 2, which is defined as the x direction; a grinder 4 is arranged on the mobile platform 23 and is used for grinding the furnace door frame.

[0048] like Figure 1 、 Figure 2 As shown, this embodiment describes an online automatic welding and grinding device for furnace door frames in a coking plant. The core structure includes a stable frame 1 as a supporting base. The equipment is equipped with a mobile platform 2, which can slide freely along the frame 1 in the z-axis direction, providing a basis for the precise positioning of the furnace door frame. A mobile platform 2 3 is further provided on this platform. Its freedom of movement is perpendicular to that of the mobile platform 2, that is, it moves along the x-axis direction. This design greatly enhances the equipment's all-round accessibility to the welding and grinding parts of the furnace door frame. The grinder 4 located on the mobile platform 2 3 is equipped with high-efficiency grinding tools and is designed specifically for precision grinding operations on the surface of the furnace door frame.

[0049] Example 2

[0050] Furthermore, it includes two lead screws 5, which are arranged on the frame 1 at intervals; two sliders 6, which are respectively arranged on the two lead screws 5; two brackets 7, which are respectively arranged on the two sliders 6, and the moving platform 2 is arranged on the two brackets 7 for movement.

[0051] like Figure 1-Figure 5 As shown, to achieve precise control and drive of the mobile platform 2, this embodiment utilizes a dual-screw 5 drive system. These two screws 5 are mounted parallel to each other on either side of the frame 1 and connected to a bracket 7 via respective sliders 6. The mobile platform 2 is placed atop this pair of brackets 7. This layout ensures smooth movement and positioning accuracy along the z-axis.

[0052] Example 3

[0053] Furthermore, it also includes a limit switch 8, and each screw 5 is provided with a limit switch 8 at the top and bottom.

[0054] like Figure 1 、 Figure 2 As shown, in terms of safety and position control, the embodiment is equipped with limit switches 8 at both ends of each lead screw 5. These switches can be triggered when the mobile platform 2 reaches a predetermined limit position, stopping the drive system in time to prevent damage or safety accidents caused by excessive travel.

[0055] Example 4

[0056] Furthermore, the slider 6 has a through slot 9, the cross section of which is T-shaped and distributed along the z-direction. The screw 5 includes a nut 10, which is located in the through slot 9 and has the same outer contour as the through slot 9. The through slot 9 also has a hole 11, and the nut 10 has a hole 2 connected to the hole 11. The hole 11 and the hole 2 are coaxial and distributed along the x-direction.

[0057] like Figure 3 As shown, the connection structure between lead screw 5 and slider 6 is specially designed. Slider 6 is embedded with a T-shaped through-slot 9. The matching nut 10 not only fits perfectly within the slot, but also connects internal hole 11 with hole 2, ensuring smooth rotation and precise transmission of lead screw 5, improving the mechanical efficiency and stability of the system.

[0058] After being assembled on the lead screw 5, the T-shaped fit between the through slot 9 and the nut 10 can well limit the position of the nut 10 in the x-axis and y-axis directions, and the hole 11 and the hole 2 designed to cross along the x-axis direction can start the thread inside and then use the screw to lock it, or use the pin to lock it, so as to limit the position of the nut 10 in the z-axis direction. In this way, the position of the nut 10 in the x, y and z directions can be limited, thereby improving the stability of the direct connection between the slider 6 and the nut 10.

[0059] Example 5

[0060] Furthermore, it also includes a connecting frame 12, one end of the connecting frame 12 is set on one of the brackets 7, and the other end is set on the other bracket 7.

[0061] like Figure 1 、 Figure 2 As shown, in order to enhance the stability of the overall structure, a connecting frame 12 is added between the equipment. It spans between the two brackets 7 on the mobile platform 2, effectively suppressing the vibration during the movement, ensuring high-precision execution of the grinding operation, and can also be used for routing.

[0062] Example 6

[0063] Furthermore, it also includes two lead screws 2 13, which are arranged at intervals on the movable platform 1 2; there are two sliders 2 14, which are respectively arranged on the two lead screws 2 13, and the movable platform 2 3 is arranged on the two sliders 2 14 to move.

[0064] like Figure 1 、 Figure 2 、 Figure 4 As shown, further refinement of the control is achieved by using a similar mechanism for precise positioning of the mobile platform 2 (3) in the x-axis direction. Two lead screws (2) (13) are positioned perpendicular to the mobile platform 1 (2) and, in conjunction with a slider (2) (14), ensure that the mobile platform 2 (3) can slide smoothly along its surface, providing the necessary work surface adjustment capability for the grinder 4. Furthermore, the slider (2) (14) can adopt the structural design of a slider (6) and a nut (10).

[0065] Example 7

[0066] Furthermore, it also includes a slide rail 15, which is arranged on the mobile platform 2 3; a slider 3 16 is slidably arranged on the slide rail 15, and the sliding direction of the slider 3 16 is perpendicular to the moving direction of the mobile platform 1 2 and the mobile platform 2 3, which is defined as the y direction; the mobile platform 3 17 is arranged on the slider 3 16, and the grinder 4 is arranged on the mobile platform 2 3 through the mobile platform 3 17, and is slidably arranged relative to the mobile platform 2 3.

[0067] like Figure 4 As shown, to increase the third degree of freedom, a slide rail 15 and a slider block 16 are added to the second mobile platform 3. The slider block 16 slides on the slide rail 15, while the third mobile platform 17 is placed on the slider block 16. This allows the grinder 4 to move not only along the x and z axes but also adjust along the y axis, achieving flexible positioning in three dimensions to accommodate various complex furnace door frame shapes.

[0068] Example 8

[0069] Furthermore, it also includes a screw three 18, one end of which is set on the mobile platform three 17, and the other end is set on the mobile platform two 3. The screw three 18 is used to drive the mobile platform three 17 to move.

[0070] like Figure 4 As shown, the control of the mobile platform 3 17 is achieved through the lead screw 3 18, which connects the mobile platform 2 3 and the mobile platform 3 17 and drives the mobile platform 3 17 along the y-axis through manual or electric operation, providing the operator with delicate manual fine-tuning capabilities to ensure the ultimate accuracy of the grinding operation.

[0071] Example 9

[0072] Furthermore, it also includes a handwheel 19, which is arranged on the screw three 18.

[0073] like Figure 1 As shown, in some operating scenarios, the handwheel 19 is directly mounted on the lead screw 3 18, allowing the operator to manually control the fine-tuning movement of the mobile platform 3 17. This method is particularly useful when fine adjustment is required, and improves the convenience of human-computer interaction.

[0074] Example 10

[0075] Furthermore, it also includes a dual-axis motor 20, which is driven and connected to the two lead screws 5.

[0076] like Figure 1 As shown, in order to drive the efficient operation of the lead screw 5, the equipment is equipped with a dual-axis motor 20, which is connected to the two lead screws 5, ensuring the fast and smooth automatic movement of the mobile platform 2 in the z-axis direction, thereby improving the overall operating efficiency.

[0077] The above embodiments demonstrate in detail the structural composition and working principle of the online automatic welding and grinding equipment for the furnace door frame of a coking plant, reflecting its high level of automation and multi-dimensional adjustment capabilities, aiming to improve production efficiency and product quality.
