Description

Technical Field

[0001] The present invention relates to the technical field of chain welding, and particularly relates to a chain conveying device for a full-automatic chain flash welding machine. Background Art

[0002] Flash welding is a resistance welding method in which when an electric current passes through the contact surfaces of two butt-jointed workpieces, the resistance of its tiny contact points and the arc on its contact surface generate heat to heat the butt-jointed surfaces. After an appropriate time, pressure is applied to the butt joint to firmly bond the entire area of the two butt-jointed surfaces together. The heat-affected zone of flash welding is extremely small and is suitable for welding thin plates or thin-walled pipe fittings. Since surface oxides and other impurities are removed as splashing sparks and are not mixed into the weld, the reliability of the weld is high.

[0003] When a link is placed longitudinally, the links on both sides can only be placed horizontally. Therefore, existing welding equipment can only weld every other link and cannot perform continuous welding. After welding is completed, the links need to be repositioned to weld the un-welded links, wasting manpower. Summary of the Invention

[0004] The object of the present invention is to overcome the above deficiencies. The present invention provides a chain conveying device for a full-automatic chain flash welding machine, which can realize automatic continuous welding of links.

Finally, only the first inclined surface contacts the corresponding third inclined surface.

[0048] Figure 4 is a schematic diagram of a clamping plate assembly clamping a chain link in an embodiment of the present invention; Figure 5 is a schematic diagram of the tilting plate pushing the chain ring to flip in an embodiment of the present invention; Figure 6 It is a schematic diagram of a chain flipped to a vertical state in an embodiment of the present invention.

[0049] The chain conveying process and principle of the fully automatic chain flash welder in this embodiment are as follows: the welding mechanism 2 located directly above the anvil 9 in the fully automatic chain flash welder descends to complete the welding of the chain link 4 seams longitudinally arranged on the anvil 9, and then resets. Then the fifth linear drive unit drives the insertion rod to insert the chain, and the fourth linear drive unit 24 drives the insertion rod to move a chain link 4 distance along the chain output direction, so that the next flat chain link 4 is placed on the anvil 9 as the chain link 4 to be welded.

[0050] Next, the first linear drive unit 13 drives the flip plate 18 forward, and the flip plate 18 drives the Y-shaped frame 14 to rise. The first inclined block 15 (if the first inclined block 15 is on the left at this time) first contacts the third inclined block 17 directly above it, and drives the clamping plate 7 on the left as the driving plate to move inward, so that the driving plate enters the yielding groove 11. At this time, the inclined plate on the driving plate is located directly below the ring hole of the chain link 4 to be welded, and the corresponding arc groove is located directly below the left arm of the chain link 4 to be welded, and the inclined plate of the other clamping plate 7 is located on the outside of the chain link 4. The third linear drive mechanism drives the anvil plate 9 to descend, and the driving plate drives the anvil plate 9 away from the chain link 4 to be welded, and then stops, as shown in FIG. Figure 4 The first linear drive unit 13 drives the flip plate 18 to rise, and at this time, the first tilting block 15 and the second tilting block 16 are in contact with the two third tilting blocks 17 respectively. The first tilting block 15 and the second tilting block 16 rise, driving the two third tilting blocks 17 to move inward, and the right tilting plate pushes the right arm of the chain link 4 to flip downward, and then the second tilting block 16 is no longer in contact with the third tilting block 17 on the corresponding side, so that the clamping plate 7 on this side no longer moves inward, so as to prevent the tilting plate on this side from interfering with the tilting plate on the other side, as shown in FIG. Figure 5The driving plate continues to move inward until the right arm of the welded chain link 4 turns downward to face the chain clamping groove 10 at the lower side. At this time, the ring seam of the chain link 4 faces upward, and then stops. Figure 6 As shown. The third linear drive mechanism drives the anvil plate 9 to reset, and then the output end of the first linear drive unit 13 is reset, the chain link 4 to be welded is placed upright in the chain clamping groove 10, and the two clamping plates 7 are reset under the action of the elastic recovery member. The pressing mechanisms 3 on both sides of the second horizontal direction above the anvil plate 9 push the chain link 4 to be welded inward to adjust its position, and press the chain link 4 to be welded, and the welding mechanism 2 presses the chain link 4 to be welded.

[0051] The fourth linear drive unit 24 drives the plunger to move a link 4 distance along the chain output direction, so that the next flat link 4 is placed on the anvil 9 as the link 4 to be welded. The telescopic end of the second linear drive unit 23 extends out, and based on the principle of the crank slider mechanism, the second connecting rod 22 drives the telescopic shaft to rotate, so that the Y-shaped frame 14 flips 180°, allowing the first tilting block 15 and the second tilting block 16 to exchange positions.

[0052] Next, the first linear drive unit 13 drives the flip plate 18 forward, and the flip plate 18 drives the Y-shaped frame 14 to rise. The first tilting block 15 first contacts the third tilting block 17 directly above it, and drives the clamping plate 7 on the right side as the driving plate to move inward, so that the driving plate enters the clearance groove 11. At this time, the tilting plate on the driving plate is located directly below the ring hole of the chain link 4 to be welded, and the corresponding arc groove is located directly below the right arm of the chain link 4 to be welded, and the tilting plate of the other clamping plate 7 is located outside the chain link 4. The third linear drive mechanism drives the anvil plate 9 to descend, and the driving plate drives the anvil plate 9 away from the chain link 4 to be welded, and then stops. The first linear drive unit 13 drives the flip plate 18 to rise. At this time, the first tilted block 15 and the second tilted block 16 contact the two third tilted blocks 17 respectively. The first tilted block 15 and the second tilted block 16 rise, driving the two third tilted blocks 17 to move inward. The left tilted plate pushes the left arm of the chain link 4 to flip downward. The left arm flips to the bottom and faces the chain clamping groove 10 on the lower side. The annular seam of the chain link 4 to be welded faces upward, and then stops. The third linear drive mechanism drives the anvil plate 9 to reset, and then the output end of the first linear drive unit 13 is reset. The chain link 4 to be welded is placed upright in the chain clamping groove 10, and the two clamping plates 7 are reset under the action of the elastic recovery member. The two-side pressing mechanism 3 in the second horizontal direction above the anvil plate 9 pushes the chain link 4 to be welded inward and presses it.

[0053] The fifth linear drive unit drives the insertion rod to withdraw from the chain (reset). The fourth linear drive part 24 drives the insertion rod to move two link distances in the reverse direction of the chain output direction (i.e., return to the initial position), and the fifth linear drive unit drives the insertion rod to insert into the chain. The telescopic end of the second linear drive part 23 retracts. Based on the principle of the crank-slider mechanism, the second connecting rod 22 and the second connecting rod 22 drive the telescopic shaft to rotate, causing the Y-shaped frame 14 to reverse 180°, so that the first inclined block 15 and the second inclined block 16 exchange positions. Then repeat the above steps.

[0054] In summary, this is a specific application example of the present invention, which does not limit the protection scope of the present invention. Technical solutions using equivalent substitutions all fall within the protection scope of the present invention.
