Description

Technical Field

[0001] This application belongs to the field of indirect resistance welding technology, and particularly relates to a connection mechanism and tooling. Background Technology

[0002] Currently, in actual production processes, indirect resistance welding is used when welding multiple parts. Under normal working conditions, conventional welding guns and electrode caps are commonly used. However, in complex working conditions such as limited operating space, it is often necessary to use irregularly shaped welding guns and corresponding irregularly shaped electrode caps. These irregularly shaped welding guns and electrode caps are more expensive than conventional welding guns and electrode caps, and are applicable to fewer working conditions, resulting in low cost-effectiveness and thus causing excessively high production costs.

[0003] Therefore, reducing production costs is particularly important when performing indirect resistance welding. Utility Model Content

[0004] This application provides a connection mechanism and tooling that can solve the problem of high cost when performing indirect resistance welding.

[0005] This application provides a connection mechanism, including an electrode part and a connection part;

[0006] The connecting part has a drive connecting end and an electrode connecting end. The electrode connecting end is detachably connected to the electrode part. The drive connecting end can be connected to the output end of the motion actuator. One end of the electrode part is used to contact the part to be welded, and the other end of the electrode part is used to electrically connect to the lower electrode of the welding gun.

[0007] Optionally, the electrode section includes a first electrode and a second electrode. The first electrode is detachably connected to the electrode connection end, one end of the first electrode is detachably connected to the second electrode, and the other end of the first electrode is used for electrical connection with the lower electrode of the welding torch.

[0008] Optionally, the first electrode has a first connecting end and a second connecting end, the first connecting end being detachably connected to the electrode connecting end, and the second connecting end being detachably connected to the second electrode, wherein the first connecting end can be electrically connected to the lower electrode of the welding torch.

[0009] Optionally, the second connection end has a plug-in protrusion, and the second electrode is provided with a slot that mates with the plug-in protrusion, with an interference fit between the slot and the plug-in protrusion.

[0010] Optionally, the plug protrusion is designed in the shape of a frustum.

[0011] Optionally, the connecting mechanism also includes a transition connector, through which the drive connection end is connected to the motion actuator.

[0012] Optionally, a limiting groove is provided on the transition connector along its height direction, and a slider adapted to the groove is provided on the drive connection end.

[0013] Optionally, the electrode connection end is provided with a mounting position for accommodating the first electrode, the mounting position extending along the height direction of the electrode connection end.

[0014] Optionally, the connecting mechanism also includes a limiting member. The electrode connection end is provided with a first groove in the length direction, and the first electrode is provided with a second groove in the length direction corresponding to the first groove. When the first electrode is placed in the mounting position, the first groove and the second groove are connected. One end of the limiting member is detachably connected to the transition connector, and the other end of the limiting member extends into the first groove and the second groove. When the transition connector slides relative to the electrode connection end, the limiting member can cooperate with the first groove and the second groove to limit the sliding distance of the transition connector relative to the electrode connection end.

[0015] This application also provides a tooling, including a motion actuator and any of the above-mentioned connecting mechanisms, wherein the execution end of the motion actuator can be connected to the connecting part.

[0016] The connection mechanism provided in this application uses a conventional welding torch and a conventional electrode cap for indirect resistance welding. Other motion actuators are connected to the connection part of the connection mechanism, thereby driving the electrode part so that one end of the electrode part contacts the welding area of ​​the part to be welded. The lower electrode cap of the conventional welding torch is electrically connected to the electrode part of the connection mechanism, and the upper electrode cap of the welding torch is adjusted to the welding area of ​​the part to be welded. The electrode part and the upper electrode cap of the conventional welding torch are located on opposite sides of the part to be welded. The upper electrode cap and the electrode part move towards each other, pressing against the part to be welded, providing a certain welding pressure while conducting current, thus completing the welding. This eliminates the need for additional special-shaped welding torches and electrode caps, reducing production costs.

[0017] The tooling provided in this application adopts the aforementioned connecting mechanism and utilizes a motion actuator connected to the connecting mechanism. By adjusting the position of the connecting mechanism, it can be used with conventional welding torches and conventional electrode caps to complete welding under various working conditions, thereby reducing production costs and avoiding the need to disassemble and assemble welding torches and electrode caps under complex working conditions, thus improving production efficiency.

It should be understood that the reference numerals are also applicable to other identical parts or components.

[0052] As described in the background section, when faced with complex working conditions such as limited operating space, it is often necessary to use irregularly shaped welding torches and corresponding irregularly shaped electrode caps to weld parts. However, irregularly shaped welding torches and corresponding irregularly shaped electrode caps are more expensive than conventional welding torches and conventional electrode caps, and are applicable to fewer working conditions, resulting in low cost-effectiveness and excessively high production costs.

[0053] To address the aforementioned problems, according to one aspect of this application, one embodiment of this application provides a connection mechanism, such as... Figure 1 and Figure 2 As shown, the connecting mechanism includes an electrode part 1 and a connecting part 2; the connecting part 2 has a drive connecting end 21 and an electrode connecting end 22, the electrode connecting end 22 is detachably connected to the electrode part 1, the drive connecting end 21 can be connected to the output end of the motion actuator, one end of the electrode part 1 is used to contact the part to be welded, and the other end of the electrode part 1 is used to electrically connect to the lower electrode of the welding gun.

[0054] In this embodiment, when performing indirect resistance welding, a conventional welding torch and a conventional electrode cap are used. The connecting part 2 of the connecting mechanism of this application is connected to another motion actuator, thereby driving the electrode part 1 so that one end of the electrode part 1 contacts the welding point of the part to be welded. The lower electrode cap of the conventional welding torch is electrically connected to the electrode part 1 of the connecting mechanism, and the upper electrode cap of the welding torch is adjusted to the welding point of the part to be welded. The electrode part 1 and the upper electrode cap of the conventional welding torch are respectively located on both sides of the part to be welded. The upper electrode cap and the electrode part 1 move towards each other to squeeze the part to be welded, providing a certain welding pressure while conducting current, thereby completing the welding. It is not necessary to use an additional special-shaped welding torch and special-shaped electrode cap for welding, thus reducing production costs.

[0055] It should be noted that the aforementioned motion actuator can be any existing robotic arm, a mechanism composed of multiple cylinders or hydraulic cylinders or linkage mechanisms that can adjust the spatial posture of an object. The output end of the motion actuator is used to drive the object to achieve a spatial position or posture under the drive of the power device. The structure of the aforementioned motion actuator will not be described in detail here.

[0056] For example, both the electrode connection end 22 and the electrode part 1 are provided with threaded holes. The electrode connection end 22 and the electrode part 1 can be detachably connected by bolts. It is understood that the electrode connection end 22 and the electrode part 1 can be detachably connected by any connection method that does not affect their function, such as snap-fit ​​connection. The detachable connection in the embodiments of this application will not be described in detail here.

[0057] In some embodiments of this application, such as Figure 3 As shown, the electrode section 1 includes a first electrode 11 and a second electrode 12. The first electrode 11 is detachably connected to the electrode connection end 22. One end of the first electrode 11 is detachably connected to the second electrode 12. The other end of the first electrode 11 is used for electrical connection with the lower electrode of the welding gun.

[0058] In some embodiments of this application, the electrode part 1 needs to contact the part to be welded, which is prone to wear during the welding process. The electrode part 1 adopts a split design, and the first electrode 11 and the second electrode 12 are set to be detachably connected, which can reduce the wear of the electrode part 1. The second electrode 12 is used to contact the part to be welded, and is more prone to wear during the welding process. Therefore, the second electrode 12 is detachably connected to the first electrode 11, which facilitates the mold repair process of the second electrode 12. The electrode part 1 is detachably connected to the electrode connection end 22 through the first electrode 11, which facilitates disassembly and maintenance.

[0059] In some embodiments of this application, such as Figure 4 As shown, the first electrode 11 has a first connection end 111 and a second connection end 112. The first connection end 111 is detachably connected to the electrode connection end 22, and the second connection end 112 is detachably connected to the second electrode 12. The first connection end 111 can be electrically connected to the lower electrode of the welding gun.

[0060] The first connecting end 111 is provided with a threaded hole for easy detachable connection with the electrode connecting end 22, and the second connecting end 112 is used for easy detachable connection with the second electrode 12.

[0061] In some embodiments of this application, such as Figure 4 As shown, the second connection end 112 has a plug-in protrusion 1121, and the second electrode 12 is provided with a slot 121 that mates with the plug-in protrusion 1121. The slot 121 and the plug-in protrusion 1121 are in an interference fit.

[0062] When the slot 121 and the insertion protrusion 1121 are engaged, the second electrode 12 and the first electrode 11 are engaged. Since the slot 121 and the insertion protrusion 1121 are interference fit, a gap will be left between the first electrode 11 and the second electrode 12 when they are connected. This gap can be used to easily disassemble and separate the two electrodes.

[0063] In some embodiments of this application, such as Figures 3 to 5 As shown, the insertion protrusion 1121 is arranged in the shape of a frustum.

[0064] The aforementioned plug-in protrusion 1121 is shaped like a frustum, which facilitates production and processing.

[0065] In one specific embodiment, the number of the above-mentioned insertion protrusion 1121 is one, and it is arranged in a frustum shape. The central axis of the insertion protrusion 1121 is collinear with the central axis of the second connecting end 112. With this arrangement, when installing the first electrode 11 and the second electrode 12, it is not necessary to deliberately adjust the angle to easily snap them together.

[0066] In some specific embodiments of this application, the outer diameter of the second electrode 12 is 15 mm and the inner diameter is 12 mm, while the end face diameter of the conventional electrode cap is 6 to 8 mm. The second electrode 12 increases the contact area compared with the conventional electrode cap. When the upper electrode cap of the conventional welding gun is used in conjunction with the second electrode 12 for welding, the surface of the part will not form a weld point shape, reducing the possibility of welding defects and increasing aesthetics.

[0067] In some embodiments, the second connecting end 112 is threadedly engaged with the second electrode 12. Specifically, the electrode part 1 is cylindrical in shape, the first connecting end 111 and the second connecting end 112 are the opposite ends of the first electrode 11, the outer side wall of the second connecting end 112 is provided with threaded patterns, the second electrode 12 is provided with threaded holes, and the threaded holes of the second electrode 12 and the outer side wall of the second connecting end 112 are directly connected by threaded engagement to achieve detachable connection.

[0068] In some embodiments of this application, such as Figure 2 and Figure 7 As shown, the connecting mechanism also includes a transition connector 3, and the drive connection end 21 is connected to the motion actuator through the transition connector 3.

[0069] The transition connector 3 is connected to the drive connection end 21 to avoid direct connection between the connection part 2 and the power actuator. The transition connector provides a disconnection point to facilitate disassembly and maintenance. In actual production, the power actuator can be installed separately from the connection part 2 and the electrode part 1. It can be finally assembled by the transition connector, which reduces the installation difficulty.

[0070] In some embodiments of this application, such as Figure 2 , Figure 6 and Figure 7 As shown, a limiting groove 31 is provided on the transition connector 3 along its height direction, and a slider 211 adapted to the groove is provided on the drive connection end 21.

[0071] The aforementioned limiting groove 31 and slider 211 cooperate with each other to allow the transition connector 3 to slide relative to the electrode connection end 22. This allows the position of the connection part 2 and the electrode part 1 to be adjusted during the welding process, in addition to the motion actuator, through the sliding between the transition connection part 2 and the connection part 2, making welding more convenient.

[0072] Specifically, such as Figure 2 , Figure 6 and Figure 7 The aforementioned limiting groove 31 is a T-shaped groove, and the aforementioned slider 211 is a T-shaped slider 211 adapted to the aforementioned T-shaped groove.

[0073] For example, in one embodiment, the limiting slide 31 is provided through the transition connector 3 in the height direction, and detachable blocking plates are respectively provided at both ends of the limiting slide 31 in the height direction. When the slider 211 is installed into the limiting slide 31, the blocking plates are installed. In this way, the transition connector 3 and the connecting part 2 can move relative to each other during the welding process and do not separate from each other. This can play a certain self-adaptive role during welding and make contact with the parts to be welded faster and more conveniently.

[0074] In some embodiments of this application, such as Figure 6 As shown, the electrode connection end 22 is provided with a mounting position 221 for accommodating the first electrode 11, and the mounting position 221 extends along the height direction of the electrode connection end 22.

[0075] Specifically, the aforementioned mounting position 221 extends through the electrode connection end 22. The first electrode 11 is cylindrical in shape. The first connection end 111 has mounting grooves on both sides of the middle part in the axial direction. The mounting position 221 of the electrode connection end 22 has protrusions that are adapted to the mounting grooves. The first electrode 11 can be engaged with the protrusions of the electrode connection end 22 through the mounting grooves. The above arrangement can limit the relative displacement between the electrode connection end 22 and the first electrode 11 in the axial direction. Both ends of the first electrode 11 pass through the electrode connection end 22. One end of the first electrode 11 is detachably connected to the second electrode 12, and the other end of the first electrode 11 is used for electrical connection with the lower electrode of the welding torch.

[0076] The mounting position 221 facilitates the installation of the first electrode 11 and the electrode connection end 22. Furthermore, the above-mentioned configuration allows for easy assembly and disassembly of the first electrode 11 and the connection part 2, which is convenient for maintenance and repair.

[0077] In some embodiments of this application, such as Figure 7 As shown, the connecting mechanism also includes a limiting member 4. The electrode connecting end 22 is provided with a first groove 222 in the length direction, and the first electrode 11 is provided with a second groove 113 corresponding to the first groove 222 in the length direction. When the first electrode 11 is placed in the mounting position 221, the first groove 222 and the second groove 113 are connected. One end of the limiting member 4 is detachably connected to the transition connecting member 3, and the other end of the limiting member 4 extends into the first groove 222 and the second groove 113. When the transition connecting member 3 slides relative to the electrode connecting end 22, the limiting member 4 can cooperate with the first groove 222 and the second groove 113 to limit the sliding distance of the transition connecting member 3 relative to the electrode connecting end 22.

[0078] Specifically, the electrode connection end 22 is provided with a first groove 222 in the length direction, and the first electrode 11 is provided with a second groove 113 in the length direction corresponding to the first groove 222. After the electrode connection end 22 and the first electrode 11 are installed in place, the first groove 222 and the second groove 113 are connected. The first groove 222 and the second groove 113 are perpendicular to the axis of the electrode connection end 22 and the first electrode 11. One end of the limiting member 4 is connected to the transition connecting member 3 by a bolt, and the other end of the limiting member 4 passes through the first groove 222 and the second groove 113, which can limit the sliding distance of the transition connecting member 3 relative to the electrode connection end 22 in the height direction, and prevent the connecting part 2 from detaching from the transition connecting member 3.

[0079] During welding, the transition connector 3 can slide relative to the electrode connection end 22, which allows the electrode part 1 to make better contact with the part to be welded.

[0080] In some embodiments of this application, such as Figure 7 As shown, the connecting mechanism also includes an extension member 5, one end of which is detachably connected to the transition connector 3, and the other end is detachably connected to the motion actuator.

[0081] Specifically, the aforementioned extension piece 5 is L-shaped, with one end detachably connected to the transition connector 3 and the other end detachably connected to the output end of the motion actuator. The extension piece 5 extends the overall length of the connecting mechanism, enabling it to adapt to more working conditions, such as when the welding operation space is too narrow.

[0082] In some embodiments of this application, the electrode part 1 is made entirely of copper, and the transition connection part 2 is made of insulating material.

[0083] According to one aspect of this application, one embodiment of this application provides a tooling including a motion actuator and a connecting mechanism in any of the above embodiments, wherein the execution end of the motion actuator can be connected to the connecting part 2.

[0084] The aforementioned motion actuator can be any existing robotic arm, a mechanism composed of multiple cylinders or hydraulic cylinders or linkages that can adjust the spatial posture of an object. The output end of the motion actuator is used to drive the object to achieve a spatial position or posture under the drive of the power device, which will not be elaborated further here.

[0085] The following is a principle-based explanation of the tooling provided in this application:

[0086] Driven by an external power unit, the motion execution structure moves the connecting part 2 in space. This motion process can be manually controlled or adjusted by a controller in conjunction with a vision sensor and / or an infrared sensor to adjust the motion trajectory and final position of the output end of the motion execution structure, so that the connecting part 2 can move the electrode part 1 to the part to be welded. Then, the welding gun is controlled so that its upper electrode cap is placed at the welding position of the part to be welded. The electrode part 1 and the upper electrode cap of the conventional welding gun are located on both sides of the part to be welded. The upper electrode cap and the electrode part 1 move towards each other to squeeze the part to be welded, providing a certain welding pressure while conducting current, thereby completing the welding. There is no need to use an additional special-shaped welding gun and special-shaped electrode cap for welding, which reduces production costs.

[0087] It should be noted that the conventional welding torch mentioned in this application includes a C-shaped torch arm, electrodes fixed to the upper and lower ends of the front sidewall of the C-shaped torch arm, and a drive assembly for driving the upper electrode of the front sidewall of the C-shaped torch arm to move. For example, the specific model of the conventional welding torch can be NIMAK MG100 series and NIMAK BasicGun, etc., and the specific model of the conventional electrode cap is 39D1978 / 2 electrode cap.

[0088] The above are preferred embodiments of this application. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
