Description

Technical Field

[0001] The present invention relates to the technical field of plasma arc welding, and more specifically, the present invention relates to a plasma arc welding machine for a fixing block of a similarity simulation test bench. Background Art

[0002] The wear resistance, strength, and corrosion resistance of different metal alloys are different. The bottom of the fixing block of the similarity simulation test bench usually needs to be wear-resistant and corrosion-resistant, and the upper part needs high strength. In order to meet different needs simultaneously, plasma arc welding with different metal combinations is required. At the same time, sealant needs to be filled inside the fixing block for buffering and connection. In order to facilitate identification, marking is required. The existing plasma arc welding devices for the fixing blocks of similarity simulation test benches cannot complete these functions simultaneously. Completing these functions requires different machines, resulting in high labor costs. Moreover, due to the step-by-step process, too much time is wasted in the intermediate transfer process, leading to low overall processing efficiency. Summary of the Invention

The negative pressure machine 43 is started, and the suction cup 46 adsorbs the second workpiece 45. The second workpiece 45 is pushed to engage with the first workpiece 44. At the same time, the first workpiece 44 will press the fixing plate 37, and the sealant in the temporary storage box 33 will be squeezed into the first workpiece 44 from the glue applying nozzle 50 through the second connecting pipe 36.

[0030] Two groups of second mounting brackets 25 are fixedly connected to the upper ends of the front baffle 4 and the rear baffle 5. A marking machine 26 is fixedly connected to the upper end of each group of second mounting brackets 25; the two marking machines 26 can respectively mark the upper and lower surfaces of the first workpiece 44 and the second workpiece 45; a group of first mounting brackets 23 are fixedly connected to the upper ends of both the front baffle 4 and the rear baffle 5. A plasma arc welding machine 22 is fixedly connected to one side of each group of first mounting brackets 23; when the rear rotating shaft 41 moves in the b-c-d section, the main carriage 24 drives the second workpiece 45 and the first workpiece 44 to rotate. At this time, the sealant at the bottom of the first workpiece 44 will flow along the inner walls of the first workpiece 44 and the second workpiece 45 for one week, so that the inner walls of the first workpiece 44 and the second workpiece 45 are coated with sealant. At the same time, when the first workpiece 44 and the second workpiece 45 move to the plasma arc welding machine 22, the plasma arc welding machine 22 is started to perform plasma arc welding on the seam between the first workpiece 44 and the second workpiece 45. The heat generated by the plasma arc welding can also accelerate the drying and forming of the sealant in the first workpiece 44 and the second workpiece 45.

[0031] The conveying mechanism 49 includes four groups of second support legs 16. A sprocket 19 is fixedly connected between every two groups of the second support legs 16. A conveyor belt 18 is arranged between the two sprockets 19. A plurality of placement frames 20 are fixedly connected to the outer surface of the conveyor belt 18.

[0034] Taking Figure 1 the perspective as the main perspective, during specific operation, first, a plurality of first workpieces 44 are added into the first blanking port 28, and a plurality of second workpieces 45 are added into the second blanking port 29. In the initial state as Figure 9 shown, the first motor 13 is started to drive the rotating rod 12 to rotate clockwise, thereby driving the swing rod 6 to swing through the second sliding block 10. The swing of the swing rod 6 can drive the front rotating shaft 15 to move left and right on the front sliding groove 21 through the first sliding block 7. The main carriage 24 moves left and right following the front rotating shaft 15. The rear rotating shaft 41 slides in the rear sliding groove 42. When the rear rotating shaft 41 moves in the a - b section, the main carriage 24 moves rightward in parallel. When the rear rotating shaft 41 moves to the b - c - d section, the main carriage 24 will rotate clockwise while moving rightward. The main carriage 24 rotates from facing left to facing right. When the rear rotating shaft 41 moves to the d - e section, the main carriage 24 will move rightward in parallel. When the rear rotating shaft 41 moves to the e - d section, the main carriage 24 will move leftward in parallel. When the rear rotating shaft 41 moves to the d - c - b section, the main carriage 24 will rotate counterclockwise while moving leftward. When the rear rotating shaft 41 moves to the b - a section, the main carriage 24 will move leftward in parallel. When the main carriage 24 moves from left to right, the rotating rod 12 rotates at a large angle and the moving speed of the main carriage 24 is slower. When the main carriage 24 moves from right to left, the rotating rod 12 rotates at a small angle and the moving speed of the main carriage 24 is faster. The device operates according to Figure 9 - Figure 1 - Figure 7 - Figure 8 - Figure 9Sequential movement; In the initial state, as Figure 9 shown, at this time, the rear rotating shaft 41 is located at point c. The first workpiece 44 and the second workpiece 45 in the first blanking port 28 and the second blanking port 29 fall onto the working platform 3. The first motor 13 is started. When the rear rotating shaft 41 moves in the b-a section, the main carriage 24 will push the second workpiece 45 to the left. The negative pressure machine 43 is started, and the suction cup 46 adsorbs the second workpiece 45. The second workpiece 45 is pushed to engage with the first workpiece 44. At the same time, the first workpiece 44 will press the fixed plate 37, and the sealant in the temporary storage box 33 will pass through the second connecting pipe 36 and be extruded from the glue spraying nozzle 50 into the first workpiece 44. (The extruded sealant is just enough to flow around the inner walls of the first workpiece 44 and the second workpiece 45); When the rear rotating shaft 41 moves in the a-b section, the suction cup 46 drives the combination of the second workpiece 45 and the first workpiece 44 to move to the right. (The second workpiece 45 and the first workpiece 44 are clamped). The sealant in the glue tank 30 enters the temporary storage box 33 from the first connecting pipe 31. When the second workpiece 45 and the first workpiece 44 move to directly below the left marking machine 26, the left marking machine 26 is started to mark the upper surfaces of the second workpiece 45 and the first workpiece 44.

[0035] When the rear rotating shaft 41 moves in the b-c-d section, the main carriage 24 drives the second workpiece 45 and the first workpiece 44 to rotate. (In the initial state, the main carriage 24 faces left. The swing rod 6 pushes the main carriage 24 to move to the right through the front rotating shaft 15. When the rear rotating shaft 41 reaches point b, the main carriage 24 starts to rotate (the movement and rotation of the main carriage 24 are affected by the front rotating shaft 15 and the rear rotating shaft 41). The axial distance between the front rotating shaft 15 and the rear rotating shaft 41 is exactly equal to the height difference between point b and point c. When the rear rotating shaft 41 reaches point c, the front rotating shaft 15 just moves directly above point c. At this time, the main carriage 24 just rotates 90 degrees, as Figure 7In the shown state, the main carriage 24 faces upward. Subsequently, the front rotating shaft 15 moves to the right side of the rear rotating shaft 41. At this time, the front rotating shaft 15 pulls the main carriage 24 to move rightward, and the main carriage 24 is oriented towards the right side. When the rear rotating shaft 41 moves to the position corresponding to point d, the main carriage 24 faces directly to the right. The main carriage 24 completes the subsequent 90-degree rotation, thereby completing the 180-degree flip of the main carriage 24. The whole process is smooth without dead points. During the entire rotation process, the sealant at the bottom of the first workpiece 44 will flow along the inner walls of the first workpiece 44 and the second workpiece 45 under the action of gravity (the extruded sealant is just enough to flow along the three sides of the inner walls of the first workpiece 44 and the second workpiece 45 without gaps), so that the inner walls of the first workpiece 44 and the second workpiece 45 are coated with sealant. At the same time, when the first workpiece 44 and the second workpiece 45 move to the plasma arc welder 22, the plasma arc welder 22 starts to perform plasma arc welding on the seam between the first workpiece 44 and the second workpiece 45. The heat generated by the plasma arc welding can also accelerate the drying and forming of the sealant inside the first workpiece 44 and the second workpiece 45 (after drying, the sealant can form a structure similar to rubber, which can, on the one hand, facilitate the protection of the inner walls of the first workpiece 44 and the second workpiece 45, and on the other hand, facilitate the subsequent connection of other structures to the first workpiece 44 and the second workpiece 45); When the rear rotating shaft 41 moves in the d-e section, the suction cup 46 drives the combination of the second workpiece 45 and the first workpiece 44 to move rightward. When the second workpiece 45 and the first workpiece 44 move to directly below the right marking machine 26, the right marking machine 26 starts to mark the upper surfaces of the second workpiece 45 and the first workpiece 44 (the original lower surfaces of the second workpiece 45 and the first workpiece 44), and will push the first workpiece 44 and the second workpiece 45 that have completed the plasma arc welding into the placement frame 20. Subsequently, the negative pressure machine 43 starts in the reverse direction, and then the suction cup 46 releases the second workpiece 45. The second motor 17 starts to drive the conveyor belt 18 to move one station through the sprocket 19.

[0036] Finally: The above description is only the preferred embodiment of the present invention and is not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
