Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to an auxiliary welding mechanism and a welding device. Background Art

[0002] When welding smaller workpieces and small parts, in order to ensure the quality of the product formed after welding, multi-point welding is often used. During the welding process, argon is often used as the shielding gas for welding workpieces and small parts.

[0003] The current welding method generally involves placing a protective shield over the jig holding the workpiece and small parts. Before welding, the shield is filled with argon gas. Once filled, the shield is opened, allowing the workpiece and small parts to be welded quickly using the argon's diffusion zone. While this method can achieve the required welding quality, it significantly wastes argon, resulting in high welding costs. Furthermore, the shield needs to be opened and closed for each weld, resulting in long welding cycles and low welding efficiency. Utility Model Content

After the welding is completed, the bottom wall 210b of the sleeve 210 is embedded between the small part 300 and the horizontal part 221, so that the workpiece 200 and the small part 300 form a connection structure.

[0113] See Figure 3 The present invention provides a welding device 1000, comprising a machine platform 400, an auxiliary welding mechanism 100, a gas supply mechanism 500, and a welding machine 600. The auxiliary welding mechanism 100 is used to support and position a workpiece 200 and a small part 300. The gas supply mechanism 500 is adjacent to the machine platform 400 and is used to provide an inert gas to the auxiliary welding mechanism 100. The welding machine 600 is disposed on the machine platform 400 and adjacent to the auxiliary welding mechanism 100 for multi-spot welding of the workpiece 200 and the small part 300. For example, the inert gas may be argon.

[0114] See Figure 4 To improve the safety and convenience of the welding device 1000, the welding device 1000 further includes a protective cover 700 and a switch assembly 800. The protective cover 700 is disposed on the machine platform 110, and the auxiliary welding mechanism 100 and the welding machine 600 are both accommodated within the protective cover 700.

[0115] See Figure 3 、 Figure 5 and Figure 6In some embodiments, the auxiliary welding mechanism 100 includes a support base 110, a gas guide assembly 120, and a bearing assembly 130. The support base 110 is mounted on the machine platform 400, the gas guide assembly 120 is mounted on the support base 110, and the bearing assembly 130 is detachably connected to the support base 110. The auxiliary welding mechanism 100 is used to position the workpiece 200 and the small part 300 and can introduce external inert gas into the area where the small part 300 and the horizontal portion 221 abut, thereby cooperating with the gas supply mechanism 500 and the welding machine 600 to achieve welding of the small part 300 and the horizontal portion 221.

[0116] See Figures 6 to 8 In some embodiments, the support base 110 defines a mounting groove 110a and a vent 110b. The vent 110b extends through the bottom wall of the mounting groove 110a. The gas guide assembly 120 includes a gas guide 121, a floating member 122, and an elastic member 123. The gas guide 121 is connected to the support base 110 and communicates with the mounting groove 110a, and is used to introduce inert gas into the mounting groove 110a. The floating member 122 is movably accommodated in the mounting groove 110a. The elastic member 123 is accommodated in the mounting groove 110a. The ends of the elastic member 123 elastically abut against the gas guide 121 and the floating member 122, respectively. The elastic member 123 is used to elastically push the floating member 122 against the bottom wall of the mounting groove 110a and extend to the vent 110b, thereby isolating the mounting groove 110a from the vent 110b. Exemplarily, the elastic member 123 is a spring.

[0117] See Figures 9 to 11 In some embodiments, the carrier assembly 130 includes a loading component 131 , a covering component 132 , and a locking component 133 . The loading member 131 is provided with a welding through-hole 131a, an air inlet channel 131b and a plurality of air outlet holes 131c. The plurality of air outlet holes 131c are all provided on the side wall of the welding through-hole 131a and are arranged at intervals along the circumference of the welding through-hole 131a. The air inlet channel 131b is respectively connected to the plurality of air outlet holes 131c. The sleeve 210 of the workpiece 200 is sleeved on the loading member 131. The vertical portion 222 of the workpiece 200 extends to the welding through-hole 131a. The small part 300 is accommodated in the welding through-hole 131a and abuts against the horizontal portion 221 and the bottom wall 210b of the sleeve 210. The covering member 132 is provided with a transfer through-hole 132a. The locking member 133 connects the covering member 132 and the loading member 131 so that the covering member 132 abuts the workpiece 200 to the loading member 131 and the transfer through-hole 132a is connected to the air inlet channel 131b. When the carrier assembly 130 is placed on the support base 110 , the cover member 132 pushes the floating member 122 to compress the elastic member 123 so that the installation groove 110 a is connected to the vent hole 110 b , and the adapter hole 132 a is connected to the vent hole 110 b .

[0118] See Figure 6 and Figure 8In some embodiments, the support base 110 includes a base plate 111, a supporting plate 112, and a plurality of supporting columns 113. The base plate 111 is mounted on the machine 400. The plurality of supporting columns 113 are connected to the base plate 111 and arranged along the circumference of the base plate 111. The supporting plate 112 is connected to the plurality of supporting columns 113. The mounting groove 110a is provided on the side of the supporting plate 112 facing the base plate 111, and the vent hole 110b is provided on the side of the supporting plate 112 facing away from the base plate 111.

[0119] In this embodiment, a clearance hole 112 a is provided in the middle of the carrier plate 112 , and an active area 110 c connected to the clearance hole 112 a is formed between the bottom plate 111 and the carrier plate 112 to facilitate installation of the carrier assembly 130 .

[0120] See Figure 7 and Figure 8 In some embodiments, the gas guide member 121 includes a mounting plate 1211 and a gas guide connector 1212. The mounting plate 1211 is detachably connected to the carrier plate 112 and is disposed on a side of the carrier plate 112 facing the base plate 111. The mounting plate 1211 is supported by the elastic member 123 and defines a mounting hole 1211a that communicates with the mounting groove 110a. One end of the gas guide connector 1212 is embedded in the mounting hole 1211a, and the other end of the gas guide connector 1212 is used to introduce inert gas.

[0121] Therefore, through the above arrangement, the assembly and disassembly of the air guide member 121 is facilitated, thereby improving the assembly and disassembly efficiency of the air guide assembly 120 .

[0122] See Figure 7 and Figure 8 In some embodiments, the air guide assembly 120 further includes a first sealing ring 124 and a second sealing ring 125. The first sealing ring 124 is positioned between the mounting plate 1211 and the carrier plate 112 and is disposed around the mounting hole 1211a. The second sealing ring 125 is embedded in the side of the carrier plate 112 facing away from the bottom plate 111 and is disposed around the vent hole 110b. The second sealing ring 125 is used to abut the cover member 132. Exemplarily, both the first sealing ring 124 and the second sealing ring 125 are rubber rings.

[0123] Therefore, the first sealing ring 124 can improve the airtightness between the mounting hole 1211 a and the mounting groove 110 a , and the second sealing ring 125 can improve the airtightness between the vent hole 110 b and the transfer through hole 132 a .

[0124] In some embodiments, the floating member 122 includes a floating body 1221 and a flexible body 1222. The floating body 1221 is housed in the mounting groove 110a and has a floating groove 1221a defined on the side facing the bottom plate 111. A portion of the elastic member 123 is housed in the floating groove 1221a. The flexible body 1222 connects to the end of the floating body 1221 facing away from the floating groove 1221a, and is configured to abut against the bottom wall of the mounting groove 110a and extend to the vent 110b, thereby isolating the mounting groove 110a from the vent 110b. Exemplarily, the flexible body 1222 is a rubber structure.

[0125] In this embodiment, the end of the flexible body 1222 away from the floating body 1221 is substantially tapered so as to fully contact the bottom wall of the mounting groove 110 a .

[0126] See Figure 5 In some embodiments, the auxiliary welding mechanism 100 further includes a pressing assembly 140. The pressing assembly 140 includes a pressing driver 141 and a pressing member 142. The pressing driver 141 is disposed on the support base 110 and connected to the pressing member 142, and is configured to drive the pressing member 142 to press the loading member 131 to secure the load-bearing assembly 130 to the support base 110. The pressing driver 141 is electrically connected to the switch assembly 800.

[0127] Exemplarily, the pressing driving member 141 is a rotary cylinder or a lifting cylinder, or a composite structure of a rotary cylinder and a lifting cylinder.

[0128] In some embodiments, the inner diameter of each gas outlet 131c is smaller than the inner diameter of the gas inlet channel 131b. Therefore, the pressure of the inert gas discharged from the gas outlet 131c is higher, which can quickly fill the mounting groove 110a, thereby shortening the welding cycle.

[0129] See Figure 9 In some embodiments, the cover member 132 includes a cover plate 1321, a stopper 1322, a pusher 1323, and a reset member 1324. The cover plate 1321 defines a receiving slot 1321a and a movable hole 1321b. The movable hole 1321b extends through the bottom wall of the receiving slot 1321a. The transfer hole 132a is defined in the cover plate 1321. The stopper 1322 connects to the cover plate 1321 and covers the receiving slot 1321a. The pusher 1323 movably passes through the movable hole 1321b and is embedded in the receiving slot 1321a to support the horizontal portion 221 of the workpiece 200 toward the loading member 131. The reset member 1324 is received in the receiving slot 1321a, and its two ends elastically abut against the stopper 1322 and the pusher 1323, respectively. Exemplarily, the reset member 1324 is a spring.

[0130] Therefore, through the above arrangement, the workpiece 200 and the loading member 131 are elastically fixed to avoid damage to the workpiece 200 .

[0131] To ensure a tight seal between the transition hole 132a and the air inlet passage 131b, the carrier assembly 130 further includes a third sealing ring 134. The third sealing ring 134 abuts between the carrier 131 and the cover plate 1321 and surrounds the transition hole 132a, enhancing the airtightness between the air inlet passage 131b and the transition hole 132a. Exemplarily, the third sealing ring 134 is a rubber structure.

[0132] See Figure 9 and Figure 10 In some embodiments, the loading member 131 defines a fixing through-hole 131d, and a stopper 1311 is disposed on the sidewall of the fixing through-hole 131d. The locking member 133 includes a handle 1331, a rotating rod 1332, and a protrusion 1333. The rotating rod 1332 is movably disposed through the cover member 132, and the two ends of the rotating rod 1332 are respectively connected to the handle 1331 and the protrusion 1333. The protrusion 1333 extends into the fixing through-hole 131d in a predetermined posture and passes through the stopper 1311. After rotating through a predetermined angle, the protrusion 1333 presses the stopper 1311 to secure the loading member 131 and the cover member 132.

[0133] In this embodiment, the air guide components 120 and the pressing components 140 are both in two groups, and the two groups of pressing components 140 are respectively arranged on the opposite sides of the avoidance through hole 112a, and the two groups of air guide components 120 are respectively arranged on the opposite sides of the avoidance through hole 112a and are located between the two groups of pressing components 140.

[0134] The welding process of the welding device 1000 is roughly as follows:

[0135] First, the carrier assembly 130 assembled with the workpiece 200 and the small component 300 is placed on the support base 110. At this time, the cover member 132 pushes against the floating member 122 to compress the elastic member 123 so that the mounting groove 110a is connected to the vent hole 110b, and the adapter hole 132a is connected to the vent hole 110b.

[0136] Then, the gas supply mechanism 500 is turned on. The inert gas from the gas supply mechanism 500 passes through the gas guide 121, the mounting groove 110a, the vent hole 110b, the transfer hole 132a, the air inlet channel 131b, and then enters the welding area of ​​the welding hole 131a from the multiple air outlet holes 131c.

[0137] Finally, the switch assembly 800 is turned on, the pressing driving member 141 drives the pressing member 142 to press the loading member 131 to fix the carrying assembly 130 to the support base 110, and the welding machine 600 welds the small piece 300 and the workpiece 200 through the welding through hole 131a.

[0138] It should be noted that the activation sequence of the air supply mechanism 500 and the switch assembly 800 can be changed based on the actual operation. The switch assembly 800 can independently control the start and stop of the pressing drive 141 and the start and stop of the welding machine 600.
