[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the specific technical solution of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0035] Example 1

[0036] The utility model provides a hardware welding jig, which can fix the hardware 6 and the PIN needle 7 during the laser welding process of the hardware 6 and the PIN needle 7 to provide support and stability.

[0037] Reference Figure 1 The utility model is a metal fitting welding jig, comprising a positioning platform 1, on which a metal fitting 6 is placed during laser welding. In a preferred embodiment, a notch 11 is provided on one side of the positioning platform 1, and the notch 11 is specifically an annular groove adapted to the metal fitting 6. Placing the metal fitting 6 in the notch 11 can improve the adaptability of the positioning platform 1 and the metal fitting 6, and can reduce the possibility of the metal fitting 6 moving at will.

[0038] A positioning column is installed on the positioning platform 1, and the positioning column is arranged at the bottom wall of the notch 11. Specifically, there are a plurality of positioning columns, and the plurality of positioning columns are spaced apart and distributed along the annular bottom wall of the notch 11. Figure 7 A positioning hole 61 is formed through the hardware 6, and the positioning hole 61 corresponds to the positioning column. When the hardware 6 is placed in the notch 11, the positioning column can pass through the positioning hole 61 to achieve the alignment operation between the positioning platform 1 and the hardware 6.

[0039] A pressing assembly 2 is provided on one side of the positioning platform 1. In a preferred embodiment, referring to Figure 2 The pressing assembly 2 includes a rotating pressure plate 21, which is specifically a horizontally arranged circular plate. The rotating pressure plate 21 is arranged on the top of the positioning platform 1. A floating positioning column 211 is arranged on the side of the rotating pressure plate 21 close to the positioning platform 1. The floating positioning column 211 is elastically connected to the rotating pressure plate 21. In some specific embodiments shown, a spring is used to connect the floating positioning column 211 and the rotating pressure plate 21. The elastic connection between the floating positioning column 211 and the rotating pressure plate 21 is not specifically limited here, and relevant technical personnel can replace and improve it on this basis. The setting of the floating positioning column 211 can pre-press the hardware 6 when the rotating pressure plate 21 rotates and presses down, so as to reduce the displacement and scratching of the hardware 6 due to excessive pressure from the rotating pressure plate 21.

[0040] One side of the rotating pressure plate 21 is connected to a rotating pressing drive member for driving the rotating pressure plate 21 to move closer to or away from the positioning platform 1. The rotating pressing drive member is preferably, but not limited to, a rotating pressing cylinder 22. The rotating pressing cylinder 22 drives the rotating pressure plate 21 to rotate and press down, so that the rotating pressure plate 21 cooperates with the positioning platform 1 to tighten and fix the hardware 6.

[0041] Reference Figure 1 and Figure 3 In a preferred embodiment, a lifting drive member 3 is provided at the bottom of the positioning platform 1, and the lifting drive member 3 includes a pneumatic slide 31, which is transmission-connected to the positioning platform 1 to drive the positioning platform 1 to move up and down. A connecting plate 32 is transmission-connected to one side of the pneumatic slide 31, and a side of the connecting plate 32 away from the pneumatic slide 31 is connected to the rotary pressing cylinder 22, so that the pneumatic slide 31 can drive the positioning platform 1 and the pressing assembly 2 to move synchronously.

[0042] Reference Figure 1 and Figure 4 A mounting plate 44 is provided on one side of the positioning platform 1 away from the rotary pressing cylinder 22. A positioning seat 4 for fixing the PIN needle 7 is installed on the mounting plate 44. The positioning seat 4 is specifically a vertically arranged column. A positioning groove 41 for placing the PIN needle 7 is provided on the top wall of the positioning seat 4. During laser welding, the PIN needle 7 can be vertically inserted into the positioning groove 41. Figure 5Further, the bottom wall of the positioning seat 4 in the positioning groove 41 is provided with an elastic member 411, and the elastic member 411 is preferably, but not limited to, a spring. When the pneumatic slide 31 drives the positioning platform 1 to descend to approach the positioning seat 4, the hardware 6 is pressed down and abuts against the PIN needle 7, and the PIN needle 7 presses the elastic member 411. The elastic member 411 is compressed, and the PIN needle 7 can reduce the gap between the hardware 6 and the PIN needle 7 under the action of the elastic force, further ensuring the welding effect of the hardware 6 and the PIN needle 7. In some specific embodiments shown in the figure, a fixing block 45 is provided at the groove wall in the positioning groove 41, and the fixing block 45 is specifically a vertically arranged long strip.

[0043] Reference Figure 4 The positioning seat 4 is provided with a clamping assembly 5 for clamping the PIN needle 7. The clamping assembly 5 includes a first clamping block 51 and a second clamping block 52. The first clamping block 51 and the second clamping block 52 are arranged opposite to each other and are located on both sides of the fixing block 45. The clamping end of the first clamping block 51 penetrates the positioning seat 4 to the positioning groove 41, and the first clamping block 51 is slidably connected to the positioning seat 4. At this time, the positioning seat 4 has a limiting effect on the sliding of the first clamping block 51 at the penetration of the first clamping block 51. The clamping end of the second clamping block 52 penetrates the positioning seat 4 to the positioning groove 41, and the second clamping block 52 is slidably connected to the positioning seat 4. The positioning seat 4 has a limiting effect on the sliding of the first clamping block 51 at the penetration of the second clamping block 52.

[0044] A clamping driver 53 is provided between the first clamping block 51 and the second clamping block 52. In some specific embodiments shown, the clamping driver 53 may be a pneumatic finger. The first clamping block 51 and the second clamping block 52 are respectively connected to the driving end of the clamping driver 53, so that the clamping driver 53 can drive the first clamping block 51 and the second clamping block 52 to approach or move toward each other, thereby achieving the first clamping block 51 and the second clamping block 52 to clamp or release the PIN needle 7. The driving method of the pneumatic finger is known to those skilled in the art and is achievable, and is not described in detail in this embodiment.

[0045] Furthermore, a pressing block 54 is provided on the opposite side of the fixing block 45. One end of the pressing block 54 close to the positioning seat 4 penetrates the positioning seat 4 to the positioning groove 41 and is slidably connected with the positioning seat 4. The pressing block 54, the first clamping block and the second clamping block are arranged around the positioning seat 4 to improve the stability of the fixation of the PIN needle 7. The pressing block 54 is transmission-connected with a clamping drive member 55. In some specific embodiments shown, the clamping drive member 55 can be a clamping cylinder. The clamping drive member 55 drives the sliding into the positioning groove 41. The pressing block 54 cooperates with the fixing block 45 to further fix the PIN needle 7.

[0046] Furthermore, a positioning sensor is provided on one side of the positioning seat 4 , and the positioning sensor is inserted into the positioning slot 41 . The positioning sensor detects the insertion status of the PIN needle 7 .

[0047] Specifically, a mounting plate 44 is provided at the bottom of the positioning seat 4, and a guide groove 441 is provided on the mounting plate 44. A guide rod 551 is slidably connected to the mounting plate 44 in the guide groove 441. One end of the guide rod 551 along the sliding direction is connected to the pressing block 54, and the other end is transmission-connected to the driving end of the pressing drive 55. When the pressing drive 55 drives the guide rod 551 and the pressing block 54 to approach the PN needle, the guide rod 551 slides in the guide groove 441 to achieve the guiding effect of the movement of the pressing block 54. A limiting plate 442 is installed at the opening of the guide groove 441 of the mounting plate 44. The limiting plate 442 limits the guide rod 551 from leaving the guide groove 441 during the sliding process, which can further improve the stability of the movement of the pressing block 54.

[0048] Reference Figure 1 and Figure 6 Before laser welding, the hardware 6 is placed in the notch 11, the positioning column cooperates with the positioning hole 61 for positioning, the rotary pressing cylinder 22 drives the rotary pressing plate 21 to rotate and press down to the positioning platform 1, and the rotary pressing plate 21 can press and fix the hardware 6 on the positioning platform 1. At this time, the PIN needle 7 is placed in the positioning groove 41, and the pressing drive 55 drives the pressing block 54 to pass through the positioning seat 4. The pressing block 54 approaches the PIN needle 7 and cooperates with the fixing block 45 to clamp and fix the PIN needle 7. The clamping drive 53 drives the first clamping block 51 and the second clamping block 52 to approach each other and then clamp the PIN needle 7. The first clamping block 51, the second clamping block 52 and the pressing block 54 realize the positioning of the PIN needle 7 around to ensure the position stability of the PIN needle 7 during welding. The pneumatic slide 31 drives the positioning platform 1 to descend, and the hardware 6 and the PIN needle 7 are pressed together. At this time, the abutment between the hardware 6 and the PIN needle 7 is laser welded. The hardware 6 and the PIN needle 7 can be quickly positioned and obtain sufficient support and stability, which effectively improves the positioning accuracy of the hardware 6 and the PIN needle 7 and the quality of welding, thereby improving the yield rate and efficiency of workpiece welding.

[0049] Example 2

[0050] In order to further improve the accuracy and consistency of positioning of the hardware 6 and the PIN needle 7, the difference between this embodiment and embodiment 1 is that, referring to Figure 1 and Figure 4 A dovetail groove 13 is provided on one side of the positioning platform 1 close to the positioning seat 4, and a dovetail block 42 is provided on one side of the positioning seat 4 close to the dovetail groove 13, and the dovetail groove 13 is matched with the dovetail block 42. When the pneumatic slide 31 drives the positioning seat 4 to descend, the dovetail block 42 slides into the dovetail groove 13, and the dovetail groove 13 and the dovetail block 42 fit each other, which can improve the positioning accuracy and consistency of the hardware 6 and the PIN needle 7, thereby ensuring the quality of welding.

[0051] Example 3
