[0032] In the description of the embodiments of the present application, unless otherwise expressly specified or limited, technical terms such as "installed," "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; internal connections between two components or interactions between two components. Those skilled in the art can understand the specific meanings of the above terms in the embodiments of the present application based on specific circumstances.

[0033] The following is combined with Figures 1 to 7 The present invention is further described in detail, but is not intended to limit the present invention.

[0034] This embodiment provides a welding auxiliary mold, including a machine platform 1 and a frame 2, the frame 2 is fixedly set on the machine platform 1, a carrying plate 11 is provided on the machine platform 1, and a first movable component 3 is provided on the frame 2. The first movable component 3 is arranged opposite to the carrying plate 11, and a carrying cavity 12 is provided on the carrying plate 11. The carrying cavity 12 matches the product 7. The first movable component 3 includes a first drive 31 and an abutment plate 32. The first drive 31 is drivingly connected to the abutment plate 32, and the abutment plate 32 is arranged corresponding to the carrying plate 11.

[0035] Specifically, the machine 1 is used to fix the entire mold, and the mold of the present application is placed stably through the machine 1. The carrying plate 11 is used to place the product 7. The shape of the carrying cavity 12 is complementary to the shape of the product 7. The product 7 is further limited by the carrying cavity 12 to prevent the position of the product 7 from deviating during welding, resulting in deviation in the welding position. The abutment plate 32 set on one side of the carrying plate 11 is moved up and down by the first drive 31. The abutment plate 32 contacts the upper surface of the carrying plate 11 by moving downward, and the product 7 is pressed by the abutment plate 32, so that the product 7 is moved upward. The limit in the downward direction, after welding is completed, the first drive 31 drives the abutment plate 32 to move upward, and the staff can easily take the product 7 out of the bearing cavity 12. Through this application, the welding efficiency of the product 7 can be greatly improved. It is only necessary to place the product 7 in the bearing cavity 12, and then the first drive 31 drives the abutment plate 32 to move downward to press the product 7, and limit the product 7 in all aspects to prevent deviation during welding, thereby ensuring the stability and quality of welding. At the same time, the first drive 31 only needs to drive the abutment plate 32 to move upward to cancel the fixation of the product 7.

[0036] In this embodiment, the carrying plate 11 is provided with a protrusion 13 , and the abutting plate 32 is provided with a groove 321 , and the groove 321 corresponds to the protrusion 13 .

[0037] Specifically, although the abutment plate 32 is arranged corresponding to the supporting plate 11, when the abutment plate 32 is driven to descend by the first drive 31, a position deviation will still occur between the abutment plate 32 and the supporting plate 11. Therefore, a protrusion 13 is provided on the supporting plate 11, and a groove 321 corresponding to the protrusion 13 is provided on the abutment plate 32. When the abutment plate 32 contacts the supporting plate 11, the protrusion 13 is placed in the groove 321, and the supporting plate 11 and the abutment plate 32 are precisely positioned by the protrusion 13 and the groove 321.

[0038] In this embodiment, the protrusions 13 are distributed at the four corners of the carrying plate 11 , and the grooves 321 are distributed at the four corners of the abutting plate 32 .

[0039] Specifically, such as Figure 3As shown, the protrusions 13 and grooves 321 in this embodiment are distributed at the four corners of the supporting plate 11 and the abutment plate 32. Since the four corners are the outermost ends of the supporting plate 11 and the abutment plate 32, the entire supporting plate 11 and the abutment plate 32 are restricted by the corners, and the protrusions 13 and the grooves 321 are used to limit the supporting plate 11 and the abutment plate 32. Therefore, setting the protrusions 13 and the grooves 321 at the outermost sides of the supporting plate 11 and the abutment plate 32 can better limit the supporting plate 11 and the abutment plate 32, so that the contact between the supporting plate 11 and the abutment plate 32 is more precise.

[0040] In this embodiment, a gap 322 is provided on the abutting plate 32 , and the gap 322 corresponds to the area to be welded on the product 7 .

[0041] Specifically, the avoidance portion 322 is an empty groove that passes through the abutment plate 32. After the abutment plate 32 contacts the supporting plate 11, the avoidance portion 322 corresponds to the position to be welded on the product 7, and the external welding component welds the product 7 through the avoidance portion 322. During welding, the supporting plate 11 supports the product 7, and the supporting cavity 12 accommodates the product 7 to fix the horizontal direction of the product 7. Then the abutment plate 32 abuts the upper side of the supporting plate 11 to limit the vertical direction of the product 7, and the external welding component welds the product 7 through the avoidance portion 322. By multiple components working together, the welding accuracy is improved.

[0042] In this embodiment, the first moving component 3 also includes a driving plate 33 and a fixed column 34. The output end of the first drive 31 passes through the frame 2 and the output end of the first drive 31 is arranged toward the supporting plate 11. The output end of the first drive 31 is connected to the driving plate 33. The driving plate 33 and the abutment plate 32 are arranged correspondingly. The fixed column 34 is arranged between the driving plate 33 and the abutment plate 32. The driving plate 33 and the abutment plate 32 are fixedly connected through the fixed column 34.

[0043] Specifically, the driving plate 33 is fixedly connected to the output end of the first driving 31, and the output end of the first driving 31 contracts and extends to drive the driving plate 33 to move up and down, and the driving plate 33 and the abutting plate 32 are connected by a fixed column 34. In this embodiment, there are multiple fixed columns 34, and multiple fixed columns 34 are located at different positions between the driving plate 33 and the abutting plate 32. When the first driving 31 drives the driving plate 33 to press downward, the abutting plate 32 also moves downward. Then the driving plate 33 distributes the pressure evenly on the surface of the abutting plate 32 through multiple fixed columns 34, so that the pressure at each position of the abutting plate 32 is the same, thereby improving the consistency of the pressure of the abutting plate 32 on the supporting plate 11.

[0044] In this embodiment, two ends of the fixing column 34 are respectively connected to four corners of the driving plate 33 and the abutting plate 32 .

[0045] Specifically, the fixing columns 34 are fixedly connected to the four corners of the supporting plate 11 and the driving plate 33. One purpose is that the corners are the outermost areas on the driving plate 33 and the abutting plate 32. The fixing columns 34 are arranged here to make the connection between the driving plate 33 and the abutting plate 32 more stable. The distance between the fixing columns 34 is the farthest distance so that the abutting plate 32 will not have a large deviation, thereby improving the consistency between the driving plate 33 and the supporting plate 11; the second purpose is that the driving plate 33 evenly distributes the pressure on the four corners of the abutting plate 32 through the four fixing columns 34, so that the pressure on each surface of the abutting plate 32 is consistent.

[0046] In this embodiment, a slide rail 5 and a slider 6 are provided between the supporting plate 11 and the machine 1. The slide rail 5 is provided on the machine 1. The slider 6 is slidably connected to the slide rail 5. The upper side of the slider 6 is fixedly connected to the bottom of the supporting plate 11. The supporting plate 11 slides on the machine 1 through the slide rail 5 and the slider 6.

[0047] Specifically, the carrying plate 11 slides on the machine 1 through the slide rail 5 and the slider 6. The specific working process is that before welding, the product 7 is placed in the carrying cavity 12, and then the carrying plate 11 is pushed toward the first moving component 3 so that the carrying plate 11 is located directly below the first moving component 3. The first drive 31 drives the driving plate 33 and the abutment plate 32 to move downward, and the abutment plate 32 contacts the carrying plate 11 to limit the product 7 in the carrying cavity 12. Then the external welding component welds the product 7 through the air avoidance portion 322. After welding, the first drive 31 drives the driving plate 33 and the abutment plate 32 to move upward, and the product 7 and the carrying plate 11 are free from the restriction. At this time, the carrying plate 11 is moved to the side away from the first moving component 3 through the slide rail 5 and the slider 6 for unloading and reloading.

[0048] In this embodiment, a second movable assembly 4 is provided on one side of the supporting plate 11, and the second movable assembly 4 includes a second drive 41, a guide block 42 and a guide column 43. The second drive 41 is fixedly provided on the machine 1, and the output end of the second drive 41 extends through the machine 1 toward the supporting plate 11. The guide block 42 is provided at the output end of the second drive 41. The guide block 42 is provided with two first mounting holes 421, and the supporting plate 11 is provided with two second mounting holes 14. The first mounting hole 421 and the second mounting hole 14 are arranged opposite to each other. Two guide columns 43 are provided, and both ends of the two guide columns 43 are placed in the first mounting hole 421 and the second mounting hole 14.

[0049] Specifically, the second moving component 4 is driven and connected to the carrying plate 11. By setting the second moving component 4, the carrying plate 11 can move automatically. Two guide columns 43 are set between the guide block 42 and the carrying plate 11. The two guide columns 43 are set in the horizontal direction. When the carrying plate 11 moves, the two guide columns 43 abut against the carrying plate 11. By abutting the carrying plate 11 and the guide block 42 with the two guide columns 43, the abutting force during the abutment is evenly distributed, so that the carrying plate 11 moves more smoothly.

[0050] In this embodiment, a limiting hole 15 is provided on the carrying plate 11 . The limiting hole 15 communicates with the carrying cavity 12 . A limiting member 16 is provided in the limiting hole 15 .

[0051] Specifically, the size of the carrying cavity 12 is intentionally set to be larger than the size of the product 7 during design, so that the product 7 can be placed for easy picking. However, when the corresponding product 7 is placed in the carrying cavity 12, the limiting member 16 abuts against the product 7 to fix the product 7 in the carrying cavity 12.

[0052] It should be noted that in this embodiment, the size of the limiting member 16 matches the size of the limiting hole 15. The limiting member 16 is a spring, which has good elastic force.

[0053] In this embodiment, a positioning hole 422 is provided on the guide block 42 , and the positioning hole 422 is arranged toward the carrying plate 11 . A positioning pin 423 corresponding to the product 7 is provided in the positioning hole 422 .

[0054] Specifically, after the product 7 is placed in the carrying cavity 12, the bottom of the product 7 is inserted into the positioning hole 422, and the product 7 is positioned through the positioning hole 422 to reduce the time for placing the product 7. The bottom of the product 7 is provided with an anti-foolproof groove 71, and the anti-foolproof groove 71 corresponds to the positioning pin 423. Only when the direction of the product 7 is placed correctly can the positioning pin 423 be placed in the anti-foolproof groove 71. The positioning pin 423 and the anti-foolproof groove 71 limit the product 7 to prevent the product 7 from flipping over, and at the same time fix the orientation of the product 7. The product 7 can only be placed in the positioning hole 422 when the orientation is correct.

[0055] In this embodiment, the first driver 31 and the second driver 41 are push cylinders.
