[0035] The following refers to Figures 1 to 8 A welding tooling of an embodiment of the present invention will be described in detail.

[0036] Referring to Figures 1 to 3 , a welding tooling according to an embodiment of the present invention includes a lower die 100, an upper die 200 and an air guiding structure. The lower die 100 is provided with a first area 101 and a second area 102. The first area 101 is used to accommodate the pole column, and the second area 102 is used to accommodate the adapter plate; the upper die 200 is used to cooperate with the lower die 100 to fix the pole column on the first area 101 and the adapter plate on the second area 102; an air guiding structure is provided on at least one of the upper die 200 and the lower die 100, and the air guiding structure is used to connect an air supply device to output gas to the welding position of the pole column and the adapter plate.

[0037] In a welding tooling of this embodiment, first, the pole column is placed on the first area 101 of the lower die 100, and then the adapter plate is placed on the second area 102 of the lower die 100 to position the pole column and the adapter plate on the lower die 100 respectively. Then, the upper die 200 is driven to cooperate with the lower die 100 to relatively fix the pole column on the first positioning structure and the adapter plate on the second positioning structure. Since the air guiding structure is connected to the air conveying device, the cooling gas can be guided to the welding area of the pole column and the adapter plate through the air guiding structure of the upper die 200 and / or the lower die 100. It can be known from the above that the welding tooling of this application can guide the cooling gas to the welding area of the pole column and the adapter plate fixed in the upper die 200 and the lower die 100 through the air guiding structure, so as to cool the welding area of the adapter plate and the pole column, reduce the temperature of the welding area of the pole column and the adapter plate, and reduce the possibility of product color difference caused by too high temperature in the welding area, thereby improving the production yield of the product.

[0038] In the following description, the air guiding structure located on the lower die 100 is denoted as the first air guiding structure 300, and the air guiding structure located on the upper die 200 is denoted as the second air guiding structure 400.

[0039] Reference Figures 2 to 4 Referring to, in some embodiments of the present invention, the lower die 100 is provided with a first air guiding structure 300. The first air guiding structure 300 includes a first air groove 310. The air inlet of the first air groove 310 is used to connect the air conveying device, the air outlet of the first air groove 310 is used to lead out the gas from the first air groove 310, and the notch of the first air groove 310 is used to output gas to the welding position of the pole column in the first area 101. The first area 101 covers the notch of the first air groove 310.

[0040] It can be understood that when the pole column is placed on the first area 101 and the adapter plate is placed on the second area 102, by matching the upper die 200 with the lower die 100, the adapter plate is closely attached to the pole column. At this time, the pole column closes the notch of the first air groove 310. The air conveying device can convey the cooling gas into the first air groove 310 through the air inlet. The cooling gas in the first air groove 310 is discharged through the air outlet of the first air groove 310, so as to form an air flow in the first air groove 310. Since the pole column closes the notch of the first air groove 310, the part of the pole column closing the notch of the first air groove 310 can be in direct contact with the cooling gas in the first air groove 310. When the cooling gas output by the air conveying device passes through the first air groove 310, the cooling gas can cool the part of the pole column closing the notch of the first air groove 310 to realize the cooling of the welding area and its adjacent areas on the pole column.

[0041] As Figure 5 shown, in some of these embodiments, the first air groove 310 is annular, and the first air groove 310 has an annular notch.

[0042] It should be noted that through holes are provided on the adapter piece. When welding between the adapter piece and the pole column, it is necessary to weld the metal around the through holes to the pole column. Therefore, the overall welding area on the pole column is annular.

[0043] It can be understood that in the welding tooling of the present invention, since the first air groove 310 is annular, the welding area on the pole column can just be entirely located at the notch of the first air groove 310. After the subsequent air supply device supplies air into the first air groove 310, the cooling gas in the first air groove 310 can fully cool the welding area on the pole column, thereby improving the cooling effect of the cooling gas on the welding area on the pole column.

[0044] In a further embodiment of the present invention, the air inlet of the first air groove 310 and the air outlet of the first air groove 310 are respectively located on opposite sides of the central axis of the first air groove 310.

[0045] It can be understood that since the first air groove 310 is annular, after the cooling gas output by the air supply device enters the first air groove 310 through the air inlet of the first air groove 310, the cooling gas can be split into two airflows in the first air groove 310. The moving directions of the two airflows are opposite, and both ultimately enter the air outlet of the first air groove 310; during the flow of the two airflows in the first air groove 310, they can respectively cool the pole column in the areas they flow through. And since the air inlet of the first air groove 310 and the air outlet of the first air groove 310 are respectively located on opposite sides of the central axis of the first air groove 310, the flow paths of the two airflows in the first air groove 310 can be shorter, so that even the airflow near the air outlet of the first air groove 310 can have a lower temperature. Correspondingly, the part of the pole column near the air outlet of the first air groove 310 can also obtain a better cooling effect, thereby improving the cooling effect of the cooling gas in the first air groove 310 on the pole column.

[0046] Reference Figure 2 and Figure 5, in some embodiments of the present invention, the lower die 100 includes a lower template 110 and a first insert 120. A first mounting hole 111 is provided on the lower template 110, and the first insert 120 is detachably arranged in the first mounting hole 111. A first air groove 310 is formed on the first insert 120. The air guiding structure further includes a first air guiding channel 320 and a second air guiding channel 330 formed in the lower template 110. The first air outlet hole of the first air guiding channel 320 is arranged on the hole wall of the first mounting hole 111, and the second air outlet hole of the second air guiding channel 330 is arranged on the hole wall of the first mounting hole 111. A ventilation hole 121 communicating with the air inlet of the first air groove 310 is provided on the first insert 120; the first insert 120 can be installed in the first mounting hole 111 in a first posture or a second posture. When the first insert 120 is in the first posture, the ventilation hole 121 communicates with the first air outlet hole; when the first insert 120 is in the second posture, the ventilation hole 121 communicates with the second air outlet hole.

[0047] It can be understood that when the first insert 120 is in the first posture, the ventilation hole 121 on the first insert 120 communicates with the first air guiding channel 320, and the second air outlet hole of the second air guiding channel 330 is closed by the first insert 120. The gas delivery device guides the cooling gas to the first air groove 310 through the first air guiding channel 320; when the first insert 120 is installed in the first mounting hole 111 in the second posture, the ventilation hole 121 on the first insert 120 can communicate with the second air guiding channel 330, and the first air outlet hole of the first air guiding channel 320 is closed by the first insert. The gas delivery device can also introduce the cooling gas into the first air groove 310 through the second air guiding channel 330. Whether the first insert 120 is installed in the first mounting hole 111 in the first posture or the second posture, the cooling gas can be input into the first air groove 310.

[0048] Specifically, an exhaust hole 122 is provided on the first insert. The exhaust hole 122 and the ventilation hole 121 are distributed on both sides of the central axis of the first air groove 310. The exhaust hole 122 communicates with the air outlet of the first air groove 310 and is used to discharge the cooling gas in the first air groove 310.

[0049] Specifically, refer to Figure 3 and Figure 5, the cross-sectional shape of the terminal post is generally oval. To fit the terminal post, the first insert block 120 is set as an oval cylinder. Correspondingly, the first mounting hole 111 is an oval hole. At this time, in addition to being installed in the first mounting hole 111 in the first posture, the first insert block 120 can also be installed in the second mounting hole 211 in the second posture where it rotates 180° around the central axis of the first mounting hole 111 by itself; for the above reasons, in some embodiments of the present invention, the first air outlet and the second air outlet are symmetrically arranged about the central axis of the first mounting hole 111 to ensure that after the first insert block 120 is installed in the first mounting hole 111, the vent hole 121 on the first insert block 120 can communicate with the first air outlet or the second air outlet.

[0050] It can be understood that since the first insert block 120 is detachably arranged in the first mounting hole 111, when the first insert block 120 is damaged due to multiple weldings, the staff can quickly replace the first insert block 120 in the first mounting hole 111.

[0051] It can be understood that the first area 101 is arranged on the first insert block 120. Correspondingly, the terminal post needs to install the first insert block 120, and for terminal posts of different specifications, the specifications of the required first insert blocks 120 will also be different; by detachably arranging the first insert block 120 in the first mounting hole 111, it enables the staff to replace the corresponding first insert block 120 in the first mounting hole 111 according to the specification of the terminal post, and the replacement of the first insert block 120 is relatively convenient.

[0052] In some embodiments of the present invention, referring to Figure 3 , a positioning groove is arranged in the first area 101, and a positioning hole is arranged in the second area 102. The adapter plate is positioned in the positioning groove of the first area 101, and the terminal post is positioned in the positioning hole of the second area 102.

[0053] Referring to Figure 2 and Figure 6 , in some embodiments of the present invention, the upper die 200 is provided with a second air guiding structure 400. The second air guiding structure 400 includes a second air groove 410, and the second air groove 410 is used to connect the air supply device and guide the air flow output by the air supply device to the welding position of the adapter plate. It can be understood that the cooling gas is conveyed to the second air groove 410 through the air supply device, and then the cooling gas flows from the second air groove 410 to the welding position of the adapter plate, thereby realizing the cooling of the welding position on the adapter plate.

[0054] Referring to Figure 2 、 Figure 6 and Figure 7 , in some of these embodiments, the upper die 200 is provided with a welding hole 200a that allows the welding laser to pass through. The second air groove 410 is annular and is arranged around the welding hole 200a.

[0055] It should be noted that through holes are provided on the adapter plate. When welding between the adapter plate and the pole column, it is necessary to weld the metal around the through holes to the pole column. That is, the welding area on the adapter plate is annular as a whole.

[0056] It can be understood that in the welding tooling of the present invention, since the second air groove 410 is annular, the notch of the second air groove 410 surrounds the welding area on the adapter plate. After the subsequent air supply device supplies air into the second air groove 410, the cooling gas in the second air groove 410 can fully cool the welding area on the adapter plate, thereby improving the cooling effect of the cooling gas on the welding area on the adapter plate.

[0057] It can be understood that since the second air groove 410 is arranged around the welding hole 200a, the welding hole 200a can be directly opposite to the junction area between the adapter plate and the pole column, so as to facilitate the subsequent welding laser to pass through the welding hole 200a to realize the welding between the adapter plate and the pole column.

[0058] It can be understood that by providing an annular first air groove 310 on the lower die 100 and an annular second air groove 410 on the upper die 200, the cooling gas in the first air groove 310 cools the welding area on the pole column, and the cooling gas output from the second air groove 410 cools the welding area on the adapter plate. Thus, the first air groove 310 and the second air groove 410 can cooperate to complete the cooling of the junction between the adapter plate and the pole column, and the cooling of the junction between the adapter plate and the pole column is more sufficient.

[0059] Such as Figure 2 and Figure 6 shown, in some embodiments, the second air groove 410 and the welding hole 200a are both located directly above the second area 102.

[0060] It can be understood that after the cooling gas output from the second air groove 410 is sprayed onto the adapter plate, a part of the cooling gas flows to the welding area of the adapter plate close to the pole column to cool the welding area of the adapter plate, and another part of the cooling gas flows to the area of the adapter plate far from the pole column to cool the area of the adapter plate far from the pole column. Thus, the cooling gas output from the second air groove 410 can cover a larger area on the upper surface of the adapter plate to improve the cooling effect on the adapter plate.

[0061] Refer to Figure 2 、 Figure 6 and Figure 8, in some embodiments, the upper die 200 includes an upper template 210 and a second insert 220. A second mounting hole 211 is provided on the upper template 210. The second insert 220 is detachably disposed within the second mounting hole 211. A second air groove 410 is formed between the second insert 220 and the hole wall of the second mounting hole 211. A welding hole 200a is provided on the second insert 220.

[0062] It can be understood that the second insert 220 is detachably mounted in the second mounting hole 211. When the second insert 220 is damaged and needs to be replaced, only the second insert 220 needs to be replaced.

[0063] Such as Figure 2 and Figure 6 As shown, in one embodiment, the horizontal height of the lower edge 210a of the second mounting hole 211 is less than the horizontal height of the lower end surface of the second insert 220, and the lower edge 210a of the second mounting hole 211 can abut against the adapter piece. It can be understood that when the upper die 200 cooperates with the lower die 100 to relatively fix the adapter piece and the pole on the lower die 100, the lower edge 210a of the second mounting hole 211 on the upper die 200 abuts against the adapter piece. The gas supply device inputs cooling gas into the second air groove 410, and the cooling gas flows along the hole wall of the second mounting hole 211 to the surface of the adapter piece. Since the horizontal height of the lower end surface of the second insert 220 is higher than the horizontal height of the lower edge 210a of the second mounting hole 211, the cooling gas diffuses towards the second insert 220 and flows out of the upper die 200 from the welding hole 200a of the second insert 220.

[0064] It can be understood that since during laser welding, the laser is welded closely along the edge of the welding hole 200a, during the process that the cooling gas flows through the second air groove 410 towards the adapter piece and flows out from the welding hole 200a, the cooling gas can fully flow through the welding area of the adapter piece, thereby making the cooling effect of the adapter piece better.

[0065] Specifically, the cooling gas used is nitrogen. When laser welding is performed, nitrogen can flow through the welding area through the second air groove 410, thereby protecting the welding area and preventing impurities in the air from affecting the welding effect.

[0066] It can also be understood that the cross-section of the lower edge 210a of the second mounting hole 211 is annular. After the lower edge 210a of the second mounting hole 211 abuts against the adapter piece, the cooling gas blown out from the second mounting hole 211 will not overflow, ensuring that the cooling gas can cover the upper surface of the adapter piece.

[0067] Refer to Figure 2In some embodiments, the second air guide structure 400 further includes a third air guide channel 420 and a fourth air guide channel 430, and the third air outlet of the third air guide channel 420 and the fourth air outlet of the fourth air guide channel 430 are both located on the groove wall of the second air groove 410, and are symmetrically arranged about the central axis of the second air groove 410. It can be understood that the third air outlet and the fourth air outlet are respectively connected to the second air groove 410, and are symmetrically arranged about the central axis of the second air groove 410. Therefore, when the third air guide channel 420 and the fourth air guide channel 430 respectively introduce the cooling gas into the second air groove 410 through the third air outlet and the fourth air outlet, since the third air outlet and the fourth air outlet are symmetrically arranged about the central axis of the second air groove 410, when the cooling gas flows into the second air groove 410 from the third air outlet and the fourth air outlet, the cooling gas can more evenly fill the second air groove 410, so that each welding part of the adapter can be fully in contact with the cooling gas, thereby improving the cooling effect of the adapter.

[0068] like Figure 2 , Figure 7 and Figure 8 As shown, in a specific embodiment of the present invention, the second mounting hole 211 is a stepped hole, the second mounting hole 211 includes a first mounting section and a second mounting section distributed in the vertical direction, the second insert 220 includes a first section 221 and a second section 222 connected to each other, the cross-sectional area of ​​the first section 221 in the horizontal direction is greater than the cross-sectional area of ​​the second section 222 in the horizontal direction, the first section 221 is located on the side of the second section 222 away from the lower mold 100, the first section 221 is penetrated in the first mounting section, the second section 222 is penetrated in the second mounting section, the horizontal side wall of the first section 221 is arranged in contact with the hole wall of the second mounting section, and the horizontal side wall of the second section 222 is arranged A second air groove 410 is formed between the first section 221 and the hole wall of the second mounting section. An annular groove 212 is provided on the upper hole edge of the second mounting section. The lower end surface of the first section 221 fits the upper hole edge of the second mounting section and closes the notch of the annular groove 212. Four evenly spaced through grooves 213 are provided on the side wall of the annular groove 212 near the welding hole 200a. The annular groove 212 is connected to the second air groove 410 through the four through grooves 213. The third air outlet and the fourth air outlet are both provided on the groove wall of the annular groove 212. The third air outlet is provided in the middle of two of the through grooves 213, and the fourth air outlet is provided in the middle of the other two through grooves 213.

[0069] It can be understood that when welding the terminal post and the adapter plate, the gas transmission device sends cooling gas into the annular groove 212 respectively from the third air outlet of the third air guide channel 420 and the fourth air outlet of the fourth air guide channel 430. The cooling gas then uniformly flows into the second air groove 410 from the through grooves 213 distributed on both sides of the third air outlet and the through grooves 213 distributed on both sides of the fourth air outlet hole, so that the cooling gas can uniformly flow out from the notch of the second air groove 410, thereby enabling the cooling gas to uniformly flow to the welding position of the adapter plate and improving the cooling effect of the adapter plate.

[0070] Specifically, four insertion holes which are evenly spaced and extend in the vertical direction are provided on the first section 221, and threaded connectors are inserted into the insertion holes. The threaded connectors are all threadedly connected to the upper template 210.

[0071] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
