Description

Technical Field

[0001] The invention relates to the technical field of continuous spot welding equipment, and in particular to a continuous spot welding equipment used in manufacturing air conditioner components. Background Art

[0002] Spot welding equipment uses a high-temperature arc generated when the positive and negative poles are short-circuited for an instant to melt the materials to be welded between the electrodes to achieve the purpose of combining them. The structure of the spot welding machine is very simple. To put it simply, it is a high-power transformer that converts 220V AC power into a low-voltage, high-current power supply, which can be either DC or AC.

[0003] In a Chinese patent (application number: CN201510490790.0), a multi-point continuous spot welding device and process are disclosed. The device includes a frame and a table.

[0005] 2. At the same time, the existing continuous spot welding equipment can generally only weld the top surface of the air-conditioning parts, so the operator needs to manually flip the air-conditioning parts after the top surface welding. This causes inconvenience to the operator in the welding operation of the air-conditioning parts, so it needs to be improved. Summary of the invention

Then the operator can put the air-conditioning frame 1 and the air-conditioning frame 2 to be spot-welded into the empty placement frame in turn for fixed spot welding in turn, thereby achieving the purpose of facilitating the loading and unloading of the air-conditioning frame 1 and the air-conditioning frame 2.

DETAILED DESCRIPTION

[0022] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] Embodiment 1, as Figure 1-Figure 6 As shown, a continuous spot welding device used for manufacturing air-conditioning components comprises a spot welding machine 1, a conveying frame 2 is fixed on the front side of the spot welding machine 1, chains 3 are respectively installed at both ends of the conveying frame 2, a placing frame 4 is annularly hinged on the chain 3, and the placing frames 4 are mutually staggered, a convex block 5 is fixed to the top of one end of the placing frame 4, a convex groove block 6 is movably sleeved on the outer surface of the convex block 5, an extrusion block 7 is fixed on the other end of the convex groove block 6, a push block 8 is slidably connected to the inclined surface of the extrusion block 7, a moving block 9 is fixed to the side of the pushing block 8, a fixed block 11 is fixed inside the placing frame 4, a round head rod 10 is movably sleeved inside the fixed block 11, one end of the round head rod 10 is fixedly sleeved with the moving block 9, a convex surface 13 is provided on the inner side surface of the conveying frame 2, and the other end of the round head rod 10 is movably connected to the convex surface 13, and an air-conditioning frame 2 24 and an air-conditioning frame 1 23 are respectively placed inside the placing frame 4.

[0024] When the air-conditioning frame 24 and the air-conditioning frame 1 23 are spot-welded, the placing frame 4 is driven to rotate by two separated chains 3, so that the placing frame 4 drives the air-conditioning frame 24 and the air-conditioning frame 1 23 to move to the bottom of the electrode of the spot welding machine 1. At this time, the placing frame 4 will drive the round head rod 10 to move along the side of the convex surface 13 through the fixed block 11, so that the convex surface 13 pushes the round head rod 10 to move along the inner wall of the fixed block 11, and then the fixed block 11 pushes the moving block 9 to move, so that the moving block 9 pushes the extrusion block 7 to squeeze and fix the air-conditioning frame 1 23 and the air-conditioning frame 2 24 through the inclined surface of the pushing block 8, and the pushing block 8 drives the convex groove block 6 to move along the outer surface of the convex block 5, and then the spot welding machine 1 moves the electrode downward to spot weld the top surfaces of the air-conditioning frame 1 23 and the air-conditioning frame 2 24. In this way, the air-conditioning frame 1 23 and the air-conditioning frame 2 24 are spot-welded in turn, so as to achieve the purpose of fixed welding in turn, so that it is more convenient for the operator to weld the air-conditioning frame 1 23 and the air-conditioning frame 2 24.

[0025] Embodiment 2, as Figure 4-Figure 6 As shown, a welding opening 14 is opened inside the placement frame 4, and the welding opening 14 is located at the connection between the air-conditioning frame 2 24 and the air-conditioning frame 1 23.

[0026] When the bottom surfaces of the air conditioning frame 1 23 and the air conditioning frame 2 24 need to be welded, at this time, since the placement frames 4 are mutually misaligned and the two chains 3 are separated, the chain 3 can rotate the air conditioning frame 2 24 and the air conditioning frame 1 23 to face upward through the placement frame 4 as a whole. During the rotation and movement, the chain 3 will drive the air conditioning frame 2 24 and the air conditioning frame 1 23 to move through the placement frame 4, and the placement frame 4 will drive the round head rod 10 to move along the side of the convex surface 13 through the fixed block 11, so that the convex surface 13 keeps squeezing the moving block 9 through the round head rod 10. , and then the moving block 9 pushes the extrusion block 7 to squeeze and fix the air-conditioning frame 1 23 and the air-conditioning frame 2 24 through the inclined surface of the pushing block 8 until the bottom surfaces of the air-conditioning frame 1 23 and the air-conditioning frame 2 24 are rotated to the bottom of the spot welding machine 1 and stop. At this time, the spot welding machine 1 moves the electrode downward through the welding port 14 to spot weld the bottom surfaces of the air-conditioning frame 1 23 and the air-conditioning frame 2 24, thereby achieving the purpose of welding the bottom surfaces of the air-conditioning frame 1 23 and the air-conditioning frame 2 24 in sequence with fixed rotation, making it more convenient for operators to weld the bottom surfaces of the air-conditioning frame 1 23 and the air-conditioning frame 24.

[0027] Embodiment three, as Figure 3-Figure 6As shown, a concave surface 21 is provided on the inner side surface of the conveying frame 2, and the concave surface 21 is smoothly connected to the convex surface 13. A limiting groove 16 is provided inside the extrusion block 7, and a limiting block 17 is movably sleeved inside the limiting groove 16. The other end of the limiting block 17 is fixedly connected to the moving block 9. The outer surface of the round head rod 10 is movably sleeved with a rigid spring 12 located between the fixed block 11 and the moving block 9. One end of the rigid spring 12 is fixedly connected to the side of the fixed block 11, and the other end of the rigid spring 12 is fixedly connected to the side of the moving block 9.

[0028] Through the design of the concave surface 21, when the chain 3 drives the placement frame 4 to rotate and move to the concave surface 21, the placement frame 4 drives the round head rod 10 to move to the concave surface 21 through the fixed block 11, so that the rigid spring 12 on the fixed block 11 will pull the moving block 9 to move, and then the moving block 9 will drive the round head rod 10 to move to the concave surface 21 to make close contact. Since the concave surface 21 is farther away from the extrusion block 7 than the convex surface 13 is from the extrusion block 7, the moving block 9 will drive the pushing block 8 to move along the side of the extrusion block 7, and then the pushing block 8 drives the limit block 17 along the limit The inner wall of the groove 16 moves, so that the pushing block 8 drives the extrusion block 7 away from the air-conditioning frame 1 23 and the air-conditioning frame 2 24 after spot welding through the limit block 17 and the limit groove 16, and the extrusion block 7 drives the convex groove block 6 to move along the outer surface of the convex block 5, so that the extrusion block 7 releases the fixing effect of the air-conditioning frame 1 23 and the air-conditioning frame 2 24, and then the operator can take the air-conditioning frame 2 24 and the air-conditioning frame 1 23 out of the placement frame 4 after spot welding, and then put the air-conditioning frame 1 23 and the air-conditioning frame 2 24 to be spot welded into the placement frame 4 in turn for spot welding.

[0029] Embodiment 4, as Figure 4 As shown, a stopper 15 is fixed inside the placement frame 4, and the stopper 15 is in contact with the second air-conditioning frame 24 and the first air-conditioning frame 23 respectively.

[0030] Through the design of the block 15, the block 15 can initially block the air-conditioning frame 24 and the air-conditioning frame 1 23 to be welded, so that the air-conditioning frame 24 and the air-conditioning frame 1 23 will not move to the outside of the placement frame 4 during the movement of the placement frame 4.

[0031] Embodiment 5, as Figure 1-Figure 3As shown, a roller conveyor 22 is fixedly installed at the bottom of the conveying frame 2, and the roller conveyor 22 is located at the lower end of the concave surface 21. A controller 25 is arranged inside the spot welding machine 1, and the controller 25 is electrically connected to the roller conveyor 22. A driving motor 18 is fixed to the side of the conveying frame 2, and the driving motor 18 is electrically connected to the controller 25. The output end of the driving motor 18 is transmission-connected with a rotating rod 20, and the other end of the rotating rod 20 passes through the conveying frame 2 and is fixedly sleeved with a sprocket 19 located between the conveying frames 2. There are two sprockets 19, and the two sprockets 19 are respectively meshed and connected with the chain 3.

[0032] By starting the driving motor 18, the rotating rod 20 drives the two sprockets 19 to rotate, and then the two sprockets 19 drive the chain 3 to rotate respectively, so that the chain 3 can drive the air-conditioning frame 1 23 and the air-conditioning frame 2 24 to move and rotate in sequence through the placing frame 4 as a whole. When the placing frame 4 drives the air-conditioning frame 1 23 and the air-conditioning frame 24 to move to the bottom of the spot welding machine 1, the controller 25 will control the driving motor 18 to stop starting, so that the convex surface 13 will push the moving block 9, the pushing block 8 and the extrusion block 7 to fix the air-conditioning frame 1 23 and the air-conditioning frame 2 24 through the round head rod 10, and the moving block 9 will stretch the rigid spring 12, and then the controller 25 will control the electrode of the spot welding machine 1 to move downward, so that the electrode of the spot welding machine 1 will be pressed against the air The top surfaces of the air conditioning frame 1 23 and the air conditioning frame 2 24 are spot welded. After spot welding, the controller 25 continues to control the drive motor 18 to start, so that the chain 3 will drive the air conditioning frame 2 24 and the air conditioning frame 1 23 after spot welding to move through the placement frame 4, and the extrusion block 7 will continue to squeeze and fix the air conditioning frame 1 23 and the air conditioning frame 2 24. When the bottom surfaces of the air conditioning frame 1 23 and the air conditioning frame 2 24 rotate to the bottom of the spot welding machine 1 electrode, the controller 25 will control the drive motor 18 to stop starting. After stopping, the spot welding machine 1 electrode is controlled by the controller 25 to move downward, so that the spot welding machine 1 electrode passes through the welding port 14 to spot weld the contact point of the bottom surface of the air conditioning frame 2 24 and the air conditioning frame 1 23. After the bottom surface is spot welded, the drive motor 1 is controlled by the controller 25. 18 continues to start, so that the chain 3 drives the spot-welded air-conditioning frame 1 23 and the air-conditioning frame 2 24 to move to the top of the roller conveyor 22 through the placement frame 4. At this time, since the chain 3 drives the placement frame 4 to rotate and move to the concave surface 21, the rigid spring 12 on the fixed block 11 will pull the round head rod 10 through the moving block 9 to move the concave surface 21 to close contact. At this time, since the concave surface 21 is farther away from the extrusion block 7 than the convex surface 13 is from the extrusion block 7, the moving block 9 drives the limit block 17 to move along the inner wall of the limit groove 16 through the pushing block 8, and then the pushing block 8 drives the extrusion block 7 away from the spot-welded air-conditioning frame 1 23 and the air-conditioning frame 2 24 through the limit block 17 and the limit groove 16, so that the spot-welded air-conditioning frame 1 23 and the air-conditioning frame 2 24 will fall. To the roller conveyor 22, at this time the controller 25 will control the roller conveyor 22 to start, so that the roller conveyor 22 will drive the air-conditioning frame 1 23 and the air-conditioning frame 2 24 to be transported to other places for subsequent processing after spot welding, when the placement frame 4 rotates to the upper end of the chain 3 and is located at the concave surface 21, the operator can put the air-conditioning frame 1 23 and the air-conditioning frame 2 24 to be spot welded into the placement frame 4 in turn, as the chain 3 continues to rotate, the placement frame 4 will rotate and move from the concave surface 21 to the convex surface 13, and then the convex surface 13 will squeeze the moving block 9 and the pushing block 8 and the extrusion block 7 through the fixed block 11 to fix the air-conditioning frame 1 23 and the air-conditioning frame 2 24 to be spot welded, so that the purpose of facilitating the loading and unloading of the air-conditioning frame 1 23 and the air-conditioning frame 2 24 is achieved.
