[0012] The present invention has the following beneficial effects: (1) In view of the fact that the welding position is affected by the arc surface of the cylinder, the present invention is provided with a welding mechanism inside the equipment. When in use, the bottom plate to be welded is placed on the top of the limit plate, the main furnace chamber is placed at the center of the bottom plate, and the clamping plate is ensured to be at the top of the main furnace chamber to ensure that the following is formed: Figure 1 In the state shown in FIG. 1 , the fixed plate 1 and the ball plate are at the two ends of the main furnace chamber, presenting the following Figure 1 The state shown, at this time, the power of the motor is turned on, the motor drives the driving wheel to rotate, and when the driving wheel rotates on the inner wall of the rolling groove, the driving wheel and the motor will drive the fixed plate 1 and the ball plate to rotate along the outer wall of the main furnace chamber through the fixed plate, and in the process of rotation of the fixed plate 1, the rolling wheel will rotate along the outer wall of the bottom plate, and the rotation of the rolling wheel will force the rotating block to push the sliding track to move up and down along the slide groove track, the sliding track drives the gear to rotate through the gear rod, and the gear drives the fixed square tube to rotate regularly through the driving column, the fixed square tube drives the welding gun to regularly swing and weld the gap between the main furnace chamber and the bottom plate, and the fixed plate 1 rotates along the outer wall of the main furnace chamber.

[0013] (2) The present invention utilizes the regular swinging characteristics of the welding gun and provides an L-shaped limit track inside the device.

[0014] (3) The present invention utilizes the characteristic that the welding gun slides on the inner wall of the L-shaped limit track, and a feeding assembly and a pushing assembly are arranged inside the equipment. When the fixed square tube drives the welding gun to move along the inner wall of the L-shaped limit track, the welding gun will contact the outer wall of the hydraulic telescopic rod 1, and the welding gun presses the hydraulic telescopic rod 1, forcing the hydraulic oil inside the hydraulic telescopic rod 1 to enter the hydraulic telescopic rod 2 through the transmission pipe 1, and the hydraulic telescopic rod 2 will extend outward, and the inclined extrusion plate 1 is pushed by the internal spring, and the side wall of the inclined extrusion plate 1 and the inner wall of the pushing block form a clamping force.

The sliding plate forces hydraulic rod one to extend through the sliding square rod. When hydraulic rod one extends, the hydraulic oil inside hydraulic rod two will be pumped into hydraulic rod one through transmission pipe two, causing hydraulic rod two to contract. The contraction of hydraulic rod two will force the inclined extrusion plate two and the pulling block to move toward the welding position. At this time, the welding rod will be pushed deeper into the welding position again due to the inclination angle of the inclined extrusion plate two and the limitation of the internal spring. Through the application of the above components, the stability of single feeding is guaranteed, and feeding deviation is avoided, which will lead to uneven welding thickness and affect the airtightness of the bottom plate and the main furnace chamber.

[0015] (4) The present invention utilizes the welding rod to pass through the inner wall of the fixed square tube during the process of penetrating. As the inclined extrusion plate 1 and the inclined extrusion plate 2 pull, the welding rod is affected by the through hole of the fixed square tube. After the welding rod passes through the through hole, the bent portion of the welding rod will be subjected to a "straightening" process. Through the application of the above components, the verticality of the welding rod is ensured while ensuring the feeding of materials, thereby avoiding the bending of the welding rod due to the continuous swing of the welding gun during the feeding process of the welding rod, resulting in a deviation in the distance between the welding rod and the welding gun, thereby affecting the hot melting efficiency of the welding rod.

By utilizing the characteristics of the above-mentioned welding gun 311 sliding on the inner wall of the L-shaped limit track 39, a feeding assembly 4 and a pushing assembly 5 are arranged inside the equipment. When the fixed square tube 310 drives the welding gun 311 to move along the inner wall of the L-shaped limit track 39, the welding gun 311 will contact the outer wall of the hydraulic telescopic rod 1 41, and the welding gun 311 presses the hydraulic telescopic rod 1 41, forcing the hydraulic oil inside the hydraulic telescopic rod 1 41 to enter the hydraulic telescopic rod 2 43 through the transmission pipe 1 42, and the hydraulic telescopic rod 2 43 produces When the hydraulic telescopic rod 43 is extended outward, the inclined extrusion plate 45 is pushed by the internal spring, and the side wall of the inclined extrusion plate 45 and the inner wall of the push block 44 form a clamping force. When the hydraulic telescopic rod 43 is extended outward, the inclined extrusion plate 45 and the push block 44 will clamp the welding strip 46 and move it to the welding position; when the welding gun 311 rotates downward, the welding gun 311 will contact the side wall of the sliding plate 52, and the welding gun 311 will push the sliding plate 52 to move along the inner wall of the L-shaped limit track 39. The sliding plate 52 forces the hydraulic rod 54 to extend through the sliding square rod 51, and the hydraulic rod 54 is pressed against the sliding square rod 51. When the pressure rod 1 54 is extended, the hydraulic oil inside the hydraulic rod 2 56 will be pumped into the hydraulic rod 1 54 through the transmission pipe 2 55, causing the hydraulic rod 2 56 to contract. The contraction of the hydraulic rod 2 56 will force the inclined extrusion plate 2 58 and the pulling block 57 to move toward the welding position. At this time, the welding rod 46 will be pushed deeper into the welding position again due to the inclination angle of the inclined extrusion plate 2 58 and the limitation of the internal spring. Through the application of the above components, the stability of single feeding is guaranteed, and feeding deviation is avoided, which will lead to uneven welding thickness and affect the airtightness of the bottom plate and the main furnace chamber.

[0031] As the welding rod 46 penetrates deeper, it will pass through the inner wall of the fixed square tube 310. As the inclined extrusion plate 1 45 and the inclined extrusion plate 2 58 pull the welding rod 46 through the through hole of the fixed square tube 310, the welding rod 46 will be affected by the through hole of the fixed square tube 310. After the welding rod 46 passes through the through hole, the bent portion of the welding rod 46 will be subjected to a "straightening" process. Through the application of the above-mentioned components, the verticality of the welding rod 46 is ensured while ensuring the feeding of the material, so as to avoid the deviation of the distance between the welding rod 46 and the welding gun 311 due to the bending of the welding rod 46 during the feeding process of the welding rod 46, thereby affecting the hot melting efficiency of the welding rod 46.
