Detailed Implementation

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 2 (The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0019] Please see Figure 1-4 This application provides a technical solution: a furnace base welding device for a high-temperature electric furnace, including a base support 5, wherein a rotary drive 6 is provided on the lower surface of the worktable 7 in the base support 5, and a bracket plate is provided on the drive end of the rotary drive 6.

[0020] The base support 5 is the basic support structure of the entire welding device, bearing the workbench 7 and various components on it. It has good stability and load-bearing capacity and is suitable for operation requirements in high-temperature environments. The workbench 7 is used to place the furnace seat workpiece and key components such as the inner support frame. The rotary drive 6 can drive the bracket plate and the inner support frame to rotate as a whole, which facilitates welding operations at different positions of the furnace seat. The bracket plate connects the rotary drive 6 and the inner support frame to transmit rotational power.

[0021] The bracket plate is provided with an inner support frame, which includes a mounting base plate 14, a lifting drive component 15, a transition plate 16, a connecting rod 13, an intermediate guide shaft 18, an intermediate mounting seat 17, a guide connecting seat 12, and a support seat 19. The mounting base plate 14 is provided on the upper surface of the workbench 7. The lifting drive component 15 is evenly distributed around the circumference of the mounting base plate 14. The output end of the lifting drive component 15 is connected to the transition plate 16. One end of the transition plate 16 is connected to the connecting rod 13. The connecting rod 13 is connected to the intermediate mounting seat 17. The intermediate mounting seat 17 is sleeved on the outer side of the intermediate guide shaft 18. The guide shaft on the guide connecting seat 12 is connected to the intermediate mounting seat 17. The support seat 19 is provided on the upper end of the guide connecting seat 12, and its through hole is coaxial with the intermediate guide shaft 18.

[0022] The lifting drive component 15 drives the adapter plate 16 to perform circular motion, causing the connecting rod 13 to undergo vertical displacement, thereby synchronously raising and lowering the support base 19. There are at least three lifting drive components 15, which are arranged around the intermediate guide shaft 18 on the upper surface of the mounting base plate 14. The two ends of the adapter plate 16 are through holes, which connect the lifting drive components 15 and the connecting rod 13 respectively, serving as the intermediate medium for power transmission. The connecting rod 13 transmits the lifting motion of the adapter plate 16 to the intermediate mounting base 17, forming a linkage structure that causes the intermediate mounting base 17 to rise and fall. The intermediate guide shaft 18 constitutes a guiding system, which is a vertical guide column on which the intermediate mounting base 17 slides to ensure a smooth lifting process. The intermediate mounting base 17 is connected to the guide connecting seat 12, which rises and falls with the intermediate mounting base 17, thereby realizing the lifting and lowering of the support base 19.

[0023] Furthermore, the support base 19 includes an intermediate mounting sleeve 9, an electric push rod 10, and an inner support plate 11. The intermediate mounting sleeve 9 is sleeved on the outside of the intermediate guide shaft 18, the electric push rod 10 is disposed on both sides of the intermediate mounting sleeve 9, and the inner support plate 11 is disposed at the end of the intermediate mounting sleeve 9.

[0024] The intermediate mounting sleeve 9 is fitted on the outside of the intermediate guide shaft 18 and serves as a support structure for the support seat 19. It is used to support the electric push rod 10 and the inner support plate 11. The electric push rod 10 provides power to drive the inner support plate 11 to open outward or close inward, thereby automatically tightening or releasing the inner wall of the furnace seat, improving operating efficiency and safety. The inner support plate 11 directly contacts the inner wall of the furnace seat, providing internal support force to prevent the furnace seat from shifting or collapsing due to thermal deformation or external force during welding. It cooperates with the outer clamping plate 8 to form a stable clamping structure.

[0025] Furthermore, the upper surface of the workbench 7 is provided with external positioning brackets 4 on both sides, the external positioning brackets 4 are screwed to the adjusting shaft 3, and the outer side of the adjusting shaft 3 is provided with an external clamping plate 8.

[0026] The outer positioning bracket 4 serves as the mounting base for the external clamping mechanism. During the welding process, it provides auxiliary support and positioning for the furnace base. It is equipped with threaded holes for adjustable connection with the adjusting shaft 3. The adjusting shaft 3 connects the outer positioning bracket 4 and the outer clamping plate 8, enabling flexible adjustment of the position of the outer clamping plate 8. This ensures that the outer clamping plate 8 is stably attached to the outer wall of the furnace base, clamping the furnace base from the outside and preventing displacement or deformation during the welding process.

[0027] Furthermore, a mounting positioning plate 20 is provided on one side of the base support 5, and an adjustment shaft 21 is rotatably connected to the mounting positioning plate 20. A welding mounting plate 20 is provided at the end of the adjustment shaft 21, and a welding component 1 is provided on the welding mounting plate 20.

[0028] The mounting plate 20 is fixed to one side of the base support 5, providing a mounting foundation for the welded part 1. It is also equipped with a rotation support and connection interface for the adjusting shaft 21. The adjusting shaft 21 rotates within it to adjust the angle of the welding mounting plate 20. The welding mounting plate 20 is rotatably connected to the rotating shaft set in the slot of the worktable 7. The angle of the welding mounting plate 20 can be adjusted by adjusting the length of the adjusting shaft 21. The welded part 1 is set on the welding mounting plate 20 and can swing within a certain range by adjusting the shaft 21. It can be flexibly adjusted for different positions, improving the flexibility of welding.

[0029] Furthermore, a vertical plate is provided on one side of the upper surface of the mounting base plate 14, and a sliding groove is provided in the vertical plate. A guide shaft is slidably arranged in the sliding groove. The guide shaft is correspondingly arranged with the mounting hole at the upper end of the connecting rod 13. An intermediate mounting seat 17 is also connected to the upper end of the connecting rod 13.

[0030] The vertical plate is fixed to one side of the mounting base plate 14 and has a sliding groove structure. The guide shaft is an auxiliary support point for the connecting rod 13 and is slidably set in the sliding groove. During the lifting process, it moves in the sliding groove to guide and stabilize, preventing the connecting rod 13 from tilting due to uneven force.

[0031] Furthermore, both the inner support plate 11 and the outer clamping plate 8 are arc-shaped structures, which are adapted to the shape of the furnace base.

[0032] The inner support plate 11 and outer clamping plate 8 with arc-shaped structure achieve a large-area, uniform pressure distribution, which is highly matched with the shape of the inner and outer walls of the furnace base, thereby improving clamping stability and welding quality.

[0033] In use: Lower the support base 19 to its lowest position, the inner support plate 11 is in the retracted state, the outer clamping plate 8 is released, the adjusting shaft 3 is in the zero position, the welding mounting plate 20 is adjusted to the default angle, the welding component 1 is not started, and the high-temperature electric furnace base to be welded is placed stably in the central area of ​​the workbench 7, ensuring that the furnace base is located between the inner support and the outer clamping mechanism for easy subsequent clamping operation. Start the lifting drive component 15 to push the adapter plate 16 upward. The adapter plate 16 drives the intermediate mounting base 17 to rise along the intermediate guide shaft 18 through the connecting rod 13. The guide shaft slides in the vertical plate groove, and the auxiliary connecting rod 13 stabilizes the transmission. Seat 17 drives guide connecting seat 12 and support seat 19 to rise as a whole. After support seat 19 reaches the set height, it stops. Start electric push rod 10: push the arc-shaped inner support plate 11 to unfold outward. The inner support plate 11 fits against the inner wall of the furnace seat, applying uniform support force to complete the internal positioning and support of the furnace seat. Adjust the adjusting shaft 3: adjust the position of the outer clamping plate 8 according to the diameter of the furnace seat. The outer clamping plate 8 moves along the adjusting shaft 3, close to the outer wall of the furnace seat, and locks the adjusting shaft 3 so that the outer clamping plate 8 fits tightly against the outer surface of the furnace seat. The arc structure design makes it fit perfectly with the furnace body, providing stable external clamping force and completing double clamping inside and outside. Inner support plate 11 The outer clamping plate 8 forms a closed-loop clamping structure to prevent the furnace base from shifting, collapsing, or deforming due to heat during the welding process. The angle of the welding mounting plate 20 is adjusted by adjusting the shaft 21 so that the welding part 1 (such as the welding gun) is accurately aligned with the part to be welded. Multiple welding mounting points can be set to achieve multi-directional welding. The rotating drive 6 is started, and the worktable 7 drives the furnace base to rotate slowly to achieve continuous welding of the weld, ensuring that the weld is uniform and beautiful. The welding part 1 is started to complete the welding.
