Description

Technical Field

[0001] The present invention relates to the technical field of welding devices, and more particularly to an electromagnetic coil pin welding device. Background Art

[0002] When welding the pins of an electromagnetic coil, a pin welding device is required. Currently, the pin welding devices used for electromagnetic coils on the market generally include a support structure and a heating structure. The support structure is usually a strip-shaped block structure, and a welding groove is provided on the support structure. During actual use, the support structure can support the welding pins of the electromagnetic coil through the welding groove, which is convenient for the heating structure to abut against the welding pins of the electromagnetic coil. When the heating structure abuts against the welding pins of the electromagnetic coil, the welding wire in contact with the welding pins can melt, and the melted welding wire can solidify at the welding part of the electromagnetic coil, thus realizing the fixation of the welding end of the electromagnetic coil and the welding pins.

[0003] Although this kind of electromagnetic coil pin welding device can indeed achieve a good welding effect on the pins of the electromagnetic coil during actual use, there is no good wire fixing structure on this kind of welding device. When welding and fixing multiple pins of the coil, the operator's hand needs to knead the wire of the coil, and then lap the kneaded and separated wire in the welding groove of the support structure. During this process, the welding difficulty of the electromagnetic coil pins will increase, and the kneaded wire is also prone to bending, which will lead to unstable contact between the wire and the welding pins, and easily cause the welding quality of the coil pins to decline. Therefore, we propose an electromagnetic coil pin welding device. Summary of the Invention

[0004] One technical problem to be solved by this application is that the wire is in unstable contact with the welding pins, which easily leads to a decline in the welding quality of the coil pins.

[0005] To solve the above technical problem, the embodiment of this application provides an electromagnetic coil pin welding device, which includes a device body and a soldering iron fixedly connected to the device body, and further includes:

[0006] Support vertical plates, which are distributed below the soldering iron. A clamping notch is provided on the support vertical plates. Wires are distributed inside the support vertical plates at the clamping notch. A cable outer skin is sleeved on the wires. The support vertical plates can support the wires.

[0007] On one side of the supporting vertical plate, there are distribution plates. On the side of the distribution plates away from the supporting vertical plate, there is a coil body.

[0008] On the side of the first clamping jaw close to the supporting vertical plate, there is a clamping cover. At the lower part of the clamping cover, there is a rotatably connected dragging cover. Inside the wall of the dragging cover, there is a fixedly connected clamping circular block. The clamping cover can cooperate with the dragging cover to drag the welding end of the coil body, enabling the welding end of the coil body to contact the welding end of the wire. At the same time, the ends of the clamping cover and the dragging cover can be inserted into the gap between the wire and the cable outer skin.

[0009] In some embodiments, a rectangular notch is opened in the middle of the clamping cover. At the part of the middle of the clamping cover close to the rectangular notch, there is a welding rod through-hole. At the part of the clamping cover and the dragging cover close to the supporting vertical plate, there are sharp corners.

[0010] In some embodiments, a pushing hydraulic cylinder is detachably connected to the side of the pushing block away from the dragging cover. The output end of the pushing hydraulic cylinder penetrates through the pushing block and is fixedly connected to a pushing plate. The pushing plate is fixedly connected to the dragging cover.

[0011] In some embodiments, a sliding strip is fixedly connected to the outer wall of the clamping cover. A support ring is sleeved on the sliding strip. The support ring is fixedly connected to the first clamping jaw.

[0012] In some embodiments, a sliding support bar is slidably connected to the lower part of the pushing block. The lower part of the sliding support bar is fixedly connected to the bottom wall of the inner cavity of the supporting notch. The side wall of the inner cavity of the pushing block is fixedly connected to an extrusion hydraulic cylinder. The output end of the extrusion hydraulic cylinder is fixedly connected to the pushing block. A plugging block is fixedly connected to the pushing block. An arc abutting plate abuts against the plugging block. The arc abutting plate is fixedly connected to the side wall of the inner cavity of the supporting notch.

[0013] In some embodiments, a fixing platform is fixedly connected to the side of the distribution plates away from the supporting vertical plate. On the top surface of the fixing platform, there is a fixedly connected support column. The support column penetrates through the coil body.

[0014] In some embodiments, a mounting bottom plate is fixedly connected to the lower part of the supporting vertical plate. The bottom surface of the mounting bottom plate is fixedly connected to the equipment body. The bottom of the distribution plates is detachably connected to a sliding groove and an electric slide rail. The fixed ends of the sliding groove and the electric slide rail are fixedly connected to the mounting bottom plate.

[0015] In some embodiments, a portion of the clamping cover close to the electrode penetration port is fixedly connected with an inserting strip, a penetration ear block is sleeved on the inserting strip, and the penetration ear block is fixedly connected to the dragging cover.

[0016] In some embodiments, the drag cover is penetrated by an abutment rod, the upper end of the abutment rod is fixedly connected to an abutment strip, the lower part of the abutment rod is abutted with an inclined abutment strip, the surface where the inclined abutment strip abuts against the abutment rod is an inclined surface, the height of the inclined surface of the inclined abutment strip close to the wire side is higher than the height of the inclined surface of the inclined abutment strip away from the wire side, a sliding bar is fixedly connected to the side of the inclined abutment strip away from the abutment rod, a sliding groove is provided on the sliding bar, a hoop strip is slidably connected to the sliding groove, a mounting strip is fixedly connected to the hoop strip, the mounting strip is fixedly connected to the outer wall of the drag cover, one end of the inclined abutment strip is fixedly connected to an extrusion plate, the extrusion plate is fixedly connected to one end of the inclined abutment strip close to the wire, and an extrusion spring is connected between the extrusion plate and the hoop strip.

[0017] In some embodiments, the inner wall of the support vertical plate is detachably connected to a slide rail platform, and the output end of the slide rail platform is detachably connected to a clamping bar. A fixing bar is distributed on the opposite side of the clamping bar, and the fixing bar is fixedly connected to the support vertical plate. The clamping bar can cooperate with the fixing bar to clamp the cable sheath on the wire.

[0018] The present invention has at least the following beneficial effects:

[0019] 1. When the welding device is actually used, the clamping cover can cooperate with the dragging cover to drive the welding end of the coil body to contact the welding end of the wire, so that the welding end of the coil body and the welding end of the wire can be stably welded.

[0020] 2. When the clamping cover in the welding device cooperates with the dragging cover to pull the welding end of the coil body, the ends of the clamping cover and the dragging cover can be inserted into the gap between the cable sheath and the wire, so as to separate the cable sheath from the wire and adjust the welding length of the wire and the coil body.

[0021] 3. When the support plate in the welding device supports the welding end of the coil body through the support notch, the extrusion hydraulic cylinder can drive the welding end of the coil body to move through the push block, which can facilitate the contact between the welding end of the coil body and the welding end of the wire.

[0022] 4. When the clamping cover and the dragging cover in the welding device drive the welding end of the coil body to contact the welding end of the wire, the cable sheath and the support plate can push the extrusion plate. At this time, the extrusion plate can drive the inclined abutment bar to slide on the hoop bar. Since the top surface of the inclined abutment bar is inclined, the extrusion plate can drive the abutment bar to lift its position through the abutment rod. At this time, the position of the welding end of the coil body can also be lifted, so that the welding liquid can be concentrated on the connection between the wire and the coil body.

[0050] A plug bar 81 is fixedly connected to the part of the clamping cover 82 close to the electrode through hole 88. A through ear block 813 is sleeved on the plug bar 81. The through ear block 813 is fixedly connected to the dragging cover 812, which can realize the stable clamping of the welding end of the coil body 3 by the clamping cover 82 and the dragging cover 812.

[0052] The support plate 33 in the welding device can stably support the coil body 3 through the fixed platform 32, and then the support notch 35 in the support plate 33 can accommodate the welding end of the coil body 3. When the hydraulic cylinder 814 is adjusted to drive the first clamping claw 8 to cooperate with the pushing block 83 to clamp the coil body 3, the clamping cover 82 can also cooperate with the dragging cover 812 to clamp the coil body 3.

When the extrusion plate 93 does not abut against the cable outer skin 4 and the supporting vertical plate 7, the repulsive force generated by the extrusion spring 98 can drive the inclined abutment bar 92 to reset through the extrusion plate 93. At this time, the abutment bar 9 can drive the height of the welding end of the coil body 3 to be lifted, so that the welding liquid at the welding end of the coil body 3 can contact the welding end of the wire 5.

[0055] Knife edges are provided at the parts of the clamping strip 61 and the fixed strips 6 in the welding device that come into contact with the cable outer sheath 4. When the clamping strip 61 and the fixed strips 6 come into contact with the cable outer sheath 4, the cable outer sheath 4 can be cut off. When the clamping cover 82 and the dragging cover 812 are in abutment, a gap for inserting the wire 5 is reserved at the sharp ends of the clamping cover 82 and the dragging cover 812.
