Description
Technical Field
[0001] This application relates to the field of automotive parts welding, and more specifically, to a long-life cerium-tungsten electrode assembly for welding automotive crankshaft components. Background Technology
[0002] In the existing automotive crankshaft forming process, welding is an essential step. When welding automotive crankshaft components, argon arc welding is mostly used. Argon arc welding is a precision welding process that uses a tungsten electrode (non-consumable electrode) as the arc igniter and argon gas as the shielding gas. The tungsten electrode is an essential component of the argon arc welding torch.
[0003] However, the existing tungsten electrodes for TIG welding torches still have the following shortcomings during use: Most of the existing tungsten electrodes for TIG welding torches use thorium tungsten needles. Because thorium tungsten electrodes wear out quickly, the thorium tungsten needles need to be frequently removed from inside the TIG welding torch, and one end of the needle needs to be ground into a conical shape. Typically, the thorium tungsten needle needs to be ground 7-8 times a day. Furthermore, after the existing tungsten needle is inserted into the TIG welding torch, the operator needs to adjust the extension length of the needle by touching the ground conical end. Since the conical end is relatively sharp, it can easily cause injury to the operator. Utility Model Content
[0004] To overcome the above shortcomings, this application provides a long-life cerium-tungsten electrode assembly for welding automotive crankshaft components. It aims to improve the problem that thorium-tungsten needles need to be frequently removed from the inside of the argon arc welding torch, and one end of the needle needs to be ground into a conical shape. Typically, the thorium-tungsten needle needs to be ground 7-8 times a day. Furthermore, after the existing needle is inserted into the argon arc welding torch, the operator needs to adjust the extension length of the needle by touching the ground conical end. Since the conical end is relatively sharp, it can easily cause injury to the operator.
[0005] This application provides a long-life cerium-tungsten electrode assembly for welding automotive crank components, including an argon arc welding torch and a cerium-tungsten needle. The argon arc welding torch has a fixing mechanism for fixing the cerium-tungsten needle and a moving mechanism for adjusting the extension length of the cerium-tungsten needle.
[0006] The fixing mechanism includes multiple sets of clamps, all of which are installed inside the argon arc welding torch.
[0007] In one specific implementation, the interior of the argon arc welding gun is provided with a second circular plate, one side of the second circular plate is connected to a connector, and one end of the connector is rotatably connected to a first circular plate.
[0008] In the above implementation process, by setting the connector, the second circular plate will not rotate with the first circular plate when the first circular plate rotates at the other end of the connector.
[0009] In one specific implementation, a plurality of moving tracks are connected to one side of the second circular plate, and moving parts are slidably connected inside the moving tracks.
[0010] In the above implementation process, by setting up a moving track, the moving part can slide inside the moving track.
[0011] In one specific implementation, a plurality of sliding grooves are formed through one side of the first circular plate, and a sliding member is slidably connected inside the sliding groove.
[0012] In the above implementation process, by setting the sliding groove, the sliding component can be driven to slide inside the sliding groove when the first circular plate rotates.
[0013] In one specific implementation, one end of the slider is connected to the outer surface of the movable member, and the other end of the slider is connected to a mounting member, which is connected to one side of the clamp.
[0014] In the above implementation process, by setting the mounting component, the first circular plate can be rotated by controlling it, which in turn drives the sliding component to slide. Since one end of the sliding component is connected to the moving component, when the sliding component slides, it drives the moving component to slide inside the moving track. Therefore, the sliding component can only move in the direction of the moving track. The movement of the sliding component drives the mounting component to move, which in turn drives the clamp to move. The cerium tungsten needle is fixed by multiple sets of clamps.
[0015] In one specific implementation, the moving mechanism includes a rotating component that is rotatably connected to the middle section of the argon arc welding torch, and the inner wall of the rotating component has multiple sets of slots.
[0016] In the above implementation process, by setting up a rotating component, the rotating component can be rotated on the outer surface of the argon arc welding torch, so that the rotating component can rotate.
[0017] In one specific implementation, the outer surface of the first circular plate is connected to multiple sets of clips, which are slidably connected inside the slot.
[0018] In the above implementation process, by setting up the card, the card can be inserted into the inside of the card slot. When the rotating part rotates, it can drive the first circular plate inside to rotate.
[0019] In one specific implementation, a fixing member is connected to the outer surface of the rotating component, and a second screw is connected to the internal thread of the fixing member. One end of the second screw is connected to a second adjusting knob.
[0020] In the above implementation process, by setting the second adjustment knob, the second screw can be rotated by operating the second adjustment knob, so that one end of the second screw passes through the fixing member and contacts the outer surface of the argon arc welding gun, thereby fixing the rotating member.
[0021] In one specific implementation, a first screw is rotatably connected to the other side of the second circular plate. One end of the first screw passes through the argon arc welding torch and is connected to a first adjustment knob. A threaded seat is threadedly connected to the outer surface of the first screw. The threaded seat is connected to the inner wall of the argon arc welding torch. A housing is connected to the other side of the second circular plate. The housing is slidably connected to the outer surface of the threaded seat.
[0022] In the above implementation process, by setting the first adjustment knob, the first screw can be rotated by operating the first adjustment knob, which in turn drives the second circular plate to move inside the argon arc welding gun, so that the housing slides on the outer surface of the threaded seat. The housing can prevent the second circular plate from rotating with the first screw. By driving the second circular plate to move, the clamp can be moved, which in turn drives the cerium tungsten needle to move inside the argon arc welding gun, and the extension length of the cerium tungsten needle can be adjusted.
[0023] In one specific implementation, a tungsten needle clip is fitted onto the outer surface of the cerium-tungsten needle, and the tungsten needle clip is disposed inside the argon arc welding torch.
[0024] In the above process, by setting up the tungsten needle clamp, the cerium tungsten needle is passed through the tungsten needle clamp and then initially fixed inside the argon arc welding gun by the tungsten needle clamp, and then clamped and fixed by multiple sets of clamps.
[0025] Compared with the prior art, the beneficial effects of this application are as follows: By setting up a fixing mechanism and a moving mechanism, and by using cerium-tungsten needles, the number of times the tungsten needles need to be ground can be reduced. Furthermore, by having the operator rotate the rotating component, the first circular plate rotates inside the argon arc welding torch, causing the sliding component to slide. Since one end of the sliding component is connected to the moving component, when the sliding component slides, it causes the moving component to slide inside the moving track. Therefore, the sliding component can only move in the direction of the moving track. The movement of the sliding component causes the mounting component to move, which in turn moves the clamps. Multiple sets of clamps fix the cerium-tungsten needles. Then, by operating the second adjusting knob, the second screw rotates, causing one end of the second screw to penetrate the fixing component and contact the outer surface of the argon arc welding torch, thus fixing the rotating component. Finally, by operating... Rotating the first adjustment knob rotates the first screw, causing the second circular plate to move inside the TIG welding torch. This allows the housing to slide on the outer surface of the threaded seat. The housing prevents the second circular plate from rotating with the first screw. Moving the second circular plate moves the clamp, which in turn moves the cerium-tungsten needle inside the TIG welding torch. This allows for adjustment of the needle's extension length, thus solving the problem of frequently removing the thorium-tungsten needle from the TIG welding torch and grinding one end into a cone shape. Typically, this requires grinding the thorium-tungsten needle 7-8 times a day. Furthermore, after inserting the needle into the TIG welding torch, operators need to adjust its extension length by touching the sharpened cone end, which can easily cause injury to operators.

[0036] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0037] Please see Figure 1 and Figure 2 This application provides a long-life cerium-tungsten electrode assembly for welding automotive crankshaft components, including an argon arc welding gun 1 and a cerium-tungsten needle 4.
[0038] Please see Figure 1 and Figure 2 The argon arc welding torch 1 is equipped with a fixing mechanism 2 for fixing the cerium tungsten needle 4, and a moving mechanism 3 for adjusting the extension length of the cerium tungsten needle 4.
[0039] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The fixing mechanism 2 includes multiple sets of clamps 208, all of which are located inside the argon arc welding gun 1.
[0040] In a specific configuration, the inside of the argon arc welding torch 1 is provided with a second circular plate 202. A connector 204 is connected to one side of the second circular plate 202. One end of the connector 204 is rotatably connected to a first circular plate 201. The connector 204 ensures that when the first circular plate 201 rotates at the other end of the connector 204, the second circular plate 202 will not rotate with the first circular plate 201.
[0041] In a specific configuration, multiple sets of moving rails 203 are connected to one side of the second circular plate 202. A moving part 205 is slidably connected inside the moving rail 203. The moving part 205 can slide inside the moving rail 203 by the setting of the moving rail 203.
[0042] In a specific configuration, multiple sets of sliding grooves 209 are provided through one side of the first circular plate 201. A sliding member 206 is slidably connected inside the sliding groove 209. By setting the sliding groove 209, the sliding member 206 can be driven to slide inside the sliding groove 209 when the first circular plate 201 rotates.
[0043] In a specific configuration, one end of the slider 206 is connected to the outer surface of the movable member 205, and the other end of the slider 206 is connected to the mounting member 207. The mounting member 207 is connected to one side of the clamp 208. By setting the mounting member 207, the first circular plate 201 can be rotated, causing the slider 206 to slide. Since one end of the slider 206 is connected to the movable member 205, when the slider 206 slides, it causes the movable member 205 to slide inside the moving track 203. Therefore, the slider 206 can only move in the direction of the moving track 203. The movement of the slider 206 causes the mounting member 207 to move, which in turn causes the clamp 208 to move. The cerium tungsten needle 4 is fixed by multiple sets of clamps 208.
[0044] In a specific configuration, the moving mechanism 3 includes a rotating component 301, which is rotatably connected to the middle section of the argon arc welding torch 1. The inner wall of the rotating component 301 has multiple sets of slots 307. By configuring the rotating component 301, the rotating component 301 can be rotated on the outer surface of the argon arc welding torch 1, so that the rotating component 301 can rotate.
[0045] In a specific configuration, the outer surface of the first circular plate 201 is connected to multiple sets of clips 303. The clips 303 are slidably connected inside the slot 307. The clips 303 can be inserted into the slot 307. When the rotating member 301 rotates, it can drive the first circular plate 201 inside to rotate.
[0046] In a specific configuration, a fixing member 304 is connected to the outer surface of the rotating component 301. A second screw 305 is threadedly connected to the inside of the fixing member 304. One end of the second screw 305 is connected to a second adjusting knob 306. By adjusting the second adjusting knob 306, the second screw 305 can be rotated, causing one end of the second screw 305 to pass through the fixing member 304 and contact the outer surface of the argon arc welding gun 1, thus fixing the rotating component 301.
[0047] In a specific configuration, a first screw 302 is rotatably connected to the other side of the second circular plate 202. One end of the first screw 302 passes through the argon arc welding torch 1 and is connected to a first adjusting knob 309. A threaded seat 308 is threaded onto the outer surface of the first screw 302 and is connected to the inner wall of the argon arc welding torch 1. A housing 3010 is connected to the other side of the second circular plate 202 and is slidably connected to the outer surface of the threaded seat 308. The first adjusting knob 309 allows for adjustment via... Rotating the first adjustment knob 309 causes the first screw 302 to rotate, which in turn moves the second circular plate 202 inside the argon arc welding gun 1. This causes the housing 3010 to slide on the outer surface of the threaded seat 308. The housing 3010 prevents the second circular plate 202 from rotating with the first screw 302. By moving the second circular plate 202, the clamp 208 can be moved, which in turn moves the cerium tungsten needle 4 inside the argon arc welding gun 1, allowing adjustment of the extension length of the cerium tungsten needle 4.
[0048] In a specific configuration, a tungsten needle clip 5 is fitted on the outer surface of the cerium-tungsten needle 4. The tungsten needle clip 5 is located inside the argon arc welding gun 1. By passing the cerium-tungsten needle 4 through the tungsten needle clip 5, the cerium-tungsten needle 4 is initially fixed inside the argon arc welding gun 1 by the tungsten needle clip 5, and then clamped and fixed by multiple sets of clamps 208.
[0049] The working principle of the long-life cerium-tungsten electrode assembly for welding automotive crankshaft components is as follows: When using the long-life cerium-tungsten electrode assembly for welding automotive crankshaft components, the use of cerium-tungsten needles 4 reduces the number of needle grinding cycles. By rotating the rotating component 301, the first circular plate 201 rotates inside the argon arc welding torch 1, causing the sliding component 206 to slide. Since one end of the sliding component 206 is connected to the moving component 205, when the sliding component 206 slides, it causes the moving component 205 to slide inside the moving track 203. Therefore, the sliding component 206 can only move in the direction of the moving track 203. The movement of the sliding component 206 causes the mounting component 207 to move, which in turn moves the clamps 208. Multiple clamps 208 fix the cerium-tungsten needles 4. Then, by operating the second adjusting knob 306, the second screw 305 rotates, causing one end of the second screw 305 to pass through the fixing component 304 and contact the argon arc welding torch 1. On the outer surface, the rotating part 301 is fixed, and then the first adjusting knob 309 is rotated to drive the first screw 302 to rotate, which in turn drives the second circular plate 202 to move inside the argon arc welding gun 1. This causes the housing 3010 to slide on the outer surface of the threaded seat 308. The housing 3010 can prevent the second circular plate 202 from rotating with the first screw 302. By driving the second circular plate 202 to move, the clamp 208 can be moved, which in turn drives the cerium tungsten needle 4 to move inside the argon arc welding gun 1. This allows for adjustment of the extension length of the cerium tungsten needle 4, thereby solving the problem that the thorium tungsten needle needs to be frequently removed from inside the argon arc welding gun 1, and one end of the needle needs to be ground into a cone shape. Typically, the thorium tungsten needle needs to be ground 7-8 times a day. Furthermore, after the existing needle is inserted into the argon arc welding gun 1, the operator needs to adjust the extension length of the needle by touching the ground cone end. Since the cone end is sharp, it can easily cause injury to the operator.
[0050] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
