[0013] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0014] As attached Figure 1 To be continued Figure 3 The present invention provides an ignition coil resistance welding device, including a fixed base 1, a clamping device 2 and a fixing device 3. The clamping device 2 is movably installed inside the fixed base 1, and the fixing device 3 is slidably installed on both ends of the top of the fixed base 1. The two ends of the clamping device 2 are movably sleeved on the outer surfaces of the two fixing devices 3.
[0015] like Figure 2 As shown, the fixed base 1 includes a base box 11, a fixed frame 12 is fixedly installed on the top of the base box 11, a top groove 13 is provided on both sides of the top of the fixed frame 12, a fixed strip 14 is fixedly installed on the top of the fixed frame 12, a sliding rail 16 is fixedly installed on the top of the fixed strip 14, a limit rod 15 is fixedly installed on both sides of both ends of the fixed strip 14, and a sliding block 35 is movably sleeved on the outer surface of the sliding rail 16.
[0016] like Figure 3As shown, the clamping device 2 includes a lifting cylinder 21 and a rotating block 24. A support block 22 is fixedly installed on the top of the lifting cylinder 21, and connecting rods 23 are fixedly installed on both sides of the support block 22.
[0017] The lifting cylinder 21 is fixedly installed inside the base box 11, the rotating block 24 is rotatably installed on the outer surface of the limiting rod 15, the top of the rotating block 24 is fixedly installed with a top rod 27, the top rod 27 has a second movable groove 28 inside, the bottom of the rotating block 24 is fixedly installed on one side of the bottom, the bottom rod 25 has a first movable groove 26 inside, the connecting rod 23 is movably installed inside the first movable groove 26, the second movable groove 28 is movably sleeved on the outer surface of the positioning rod, and the bottom rod 25 is movably installed inside the top groove 13.
[0018] In this embodiment, when the lifting cylinder 21 retracts, the support block 22 descends, pushing the connecting rod 23 to move inside the first movable groove 26 and pressing it to the lower end of the bottom rod 25. This causes the bottom rod 25 to drive the rotating block 24 to rotate around the limiting rod 15, causing the top rods 27 at both ends to push the positioning rod inside the second movable groove 28, bringing the fixing devices 3 at both ends of the top of the sliding track 16 closer to each other, thereby bringing the electrodes at both ends closer together.
[0019] like Figure 4 As shown, the fixing device 3 includes a clamping block 31 and a fixing sleeve 38. A sliding block 35 is fixedly installed at the bottom of the clamping block 31, and a sliding groove 32 is opened at the top of the clamping block 31. A fixing rod 33 is fixedly installed at both ends inside the sliding groove 32. The fixing sleeve 38 is slidably installed inside the sliding groove 32. The bottom of the fixing sleeve 38 is movably sleeved on the outer surface of the fixing rod 33. A buffer spring 34 is movably sleeved on the outer surface of one end of the fixing rod 33. The buffer spring 34 is located between the inner wall of the fixing sleeve 38 and the sliding groove 32. An adjusting bolt 36 is threadedly installed in the middle of the clamping block 31. A top ball 37 is rotatably installed at one end of the adjusting bolt 36. Positioning rods are fixedly installed on both sides of the sliding block 35.
[0020] Specifically, by rotating the adjusting bolt 36, the adjusting bolt 36 moves inside the clamping block 31, thereby adjusting the position of the top bead 37 from the clamping block 31. Therefore, when the lifting cylinder 21 retracts and the support block 22 descends, the top rod 27 pushes the fixing devices 3 at both ends to move towards each other. The top beads 37 inside the fixing devices 3 at both ends will resist each other, thereby preventing the fixing devices 3 at both ends from getting too close to each other, which would cause the electrodes at both ends to be squeezed too much and deformed, affecting the welding of the electrodes. The distance between the fixing devices 3 at both ends is controlled by adjusting the adjusting bolt 36.
[0021] In addition, through the action of the buffer spring 34, after the electrodes inside the fixed sleeves 38 at both ends are squeezed against each other, the buffer spring 34 will be compressed by the pressure of the electrodes, thereby protecting the electrodes and preventing excessive pressure on the electrodes, which would affect the welding effect.
[0022] like Figure 5 As shown, the fixed sleeve 38 includes a movable block 381 and a support frame 385. A groove is formed on the top of the support frame 385. A second magnetic block 389 is fixedly installed on one side of the top of the support frame 385. A sleeve plate 386 is rotatably installed on the top of the support frame 385. Multiple rubber anti-slip strips 387 are fixedly installed inside both the sleeve plate 386 and the groove. A first magnetic block 388 is fixedly installed on the side of the sleeve plate 386, and the first magnetic block 388 is magnetically connected to the second magnetic block 389. A limiting sleeve 3810 is fixedly installed at the bottom of the support frame 385. The inner wall of 10 is fixedly connected with a fixed internal tooth 3811, the outer surface of the fixed rod 33 is movably sleeved with a moving block 381, the top of the moving block 381 is fixedly installed with an inner support tube 382, the outer surface of the lower end of the inner support tube 382 is fixedly connected with an external gear 383, the inside of the fixed internal tooth 3811 meshes with the outer surface of the external gear 383, the top of the inner support tube 382 is fixedly connected with a return spring 384, the top of the return spring 384 is fixedly connected with the bottom of the support frame 385, and the limiting sleeve 3810 is movably sleeved on the outer surface of the inner support tube 382.
[0023] When the sleeve plate 386 is opened and the electrode is placed in the groove inside the support frame 385, the second magnetic block 389 and the first magnetic block 388 are magnetically attracted by the first magnetic block 388 through the magnetic attraction between the first magnetic block 388 and the second magnetic block 389, so that the sleeve plate 386 and the support frame 385 fix the electrode.
[0024] In this embodiment, by pulling the support frame 385 upward, the limiting sleeve 3810 rises on the outer surface of the inner support tube 382. By rotating the support frame 385, the support frame 385 is rotated to the target angle. At this time, the support frame 385 is loosened, and the limiting sleeve 3810 is sleeved on the outer surface of the inner support tube 382 by the reaction force of the reset spring 384. The fixed internal gear 3811 is sleeved on the outer surface of the external gear 383 to prevent the support frame 385 from rotating. This allows the support frames 385 at both ends to rotate to the target angle, enabling the electrodes at both ends to achieve multi-angle welding.
[0025] The working process of this utility model is as follows: In use, the two electrodes are placed inside the groove of the support frame 385, and the sleeve plate 386 is closed, so that the first magnetic block 388 and the second magnetic block 389 are magnetically attracted. The sleeve plate 386 presses the electrodes into the groove of the support frame 385 and fixes the electrodes with rubber anti-slip strips 387 to prevent the electrodes from sliding. When the lifting cylinder 21 retracts, the support block 22 descends, pushes the connecting rod 23 to move inside the first movable groove 26, and presses it to the lower end of the bottom rod 25, so that the bottom rod 25 drives the rotating block 24 to rotate around the limiting rod 15, so that the top rods 27 at both ends push the positioning rod inside the second movable groove 28, so that the fixing devices 3 at both ends of the top of the sliding track 16 come closer to each other, thereby bringing the electrodes at both ends closer together. By rotating the adjusting bolt 36, the adjusting bolt 36 moves inside the clamping block 31, thereby adjusting the position of the top ball 37 from the clamping block 31. Therefore, when the lifting cylinder 21 retracts and the support block 22 descends, the top rod 27 pushes the fixing devices 3 at both ends to move towards each other. The top balls 37 inside the fixing devices 3 at both ends will resist each other, adjusting the distance between the fixing devices 3 at both ends, and avoiding excessive compression of the electrodes at both ends, which could lead to deformation. When performing multi-angle welding on the electrodes at both ends, the support frame 385 is pulled upward to raise the limiting sleeve 3810 on the outer surface of the inner support tube 382. The support frame 385 is then rotated to the target angle. At this point, the support frame 385 is loosened, and the limiting sleeve 3810 is fitted onto the outer surface of the inner support tube 382 by the reaction force of the return spring 384. The fixed internal gear 3811 is fitted onto the outer surface of the external gear 383 to prevent the support frame 385 from rotating. This allows the welding angle of the electrodes at both ends to be adjusted, enabling multi-angle welding of the electrodes at both ends.
