[0029] like Figure 1-5 As shown, this application embodiment provides a positioning spot welding fixture, including: a base 1;

[0030] Product positioning seat 2 is located on base 1 and can rotate relative to base 1;

[0031] Support base 3 is located on one side of product positioning base 2;

[0032] The pressure claw assembly 4 includes a rotating shaft block 41, a limiting pressure claw 43, and a spring-loaded pressure claw 44. The rotating shaft block 41 is disposed on the support base 3. The limiting pressure claw 43 and the spring-loaded pressure claw 44 are respectively pivotally connected to the rotating shaft block 41 through a flipping block 42, and the other end is respectively connected to the limiting pressure claw 43 and the spring-loaded pressure claw 44. The limiting pressure claw 43 is used for welding point positioning, and the spring-loaded pressure claw 44 is used to cooperate with the limiting pressure claw 43 to perform 9-point welding on the product.

[0033] In this embodiment, the product positioning seat 2 can fix the processed product 9, and the flipping block 42 is used to drive the limiting pressure claw 43 and the spring pressure claw 44 to flip.

[0034] Specifically, the mobile phone product 9 is fixed on the product positioning seat 2, and then the limiting claw 43 is flipped so that the limiting claw 43 rotates to the spot welding position. The limiting claw 43 can limit and position the spot welding position. Then the spring claw 44 is flipped so that the spring claw 44 and the limiting claw 43 cooperate to press the spring of the spot welding part and perform spot welding simultaneously. After welding, the limiting claw 43 and the spring claw 44 are rotated back to their original positions, and the spot welded product 9 is taken out.

[0035] By setting the limiting claw 43 and the spring clip claw 44, the limiting claw 43 can position and limit the welding part of the product 9. The spring clip claw 44 cooperates with the limiting claw 43 to press the spring clip of the welding part and perform spot welding, which effectively solves problems such as spring clip misalignment, poor welding, and weld point misalignment.

[0036] In one embodiment, the limiting claw 43 includes a first body 431, and a positioning hole 432 is provided at the other end of the first body 431.

[0037] The spring clip claw 44 includes a second body 441 and a welding pin 442. The welding pin 442 is disposed at the other end of the second body 441 and has an angle with the second body 441.

[0038] In this embodiment, the shape of the positioning hole 432 matches the shape of the spot welding part. The second body 441 and the welding needle 442 are integrally formed, and the welding needle 442 bends downward to form an angle with the second body 441. The angle α between the second body 441 and the welding needle 442 is 90°. During spot welding, the welding needle 442 passes through the positioning hole 432 to weld the spot welding part.

[0039] During operation, the mobile phone product 9 is first fixed on the product positioning seat 2, and then flipped to connect with the limiting claw 43. This causes the limiting claw 43 to flip, so that the limiting claw 43 rotates to the spot welding position, so that the positioning hole 432 is aligned with the spot position, and the spot welding position is limited and positioned. Then, the flipping block 42 connected to the spring piece claw 44 is flipped, so that the welding pin 442 of the spring piece claw 44 passes through the positioning hole 432 and presses the spring piece of the spot welding part, and spot welding is performed simultaneously. After welding, the limiting claw 43 and the spring piece claw 44 are rotated back to their original positions, and the spot welded product 9 is taken out.

[0040] In one embodiment, the pressure claw assembly 4 further includes two flipping blocks 42, one end of which is pivotally connected to the rotating shaft block 41, and the other end of which is detachably fixedly connected to the limiting pressure claw 43 and the spring plate pressure claw 44.

[0041] In this embodiment, a rotating shaft is provided inside the rotating shaft block 41, and the flipping block 42 is sleeved on the rotating shaft inside the rotating shaft block 41. The flipping block 42 flips and drives the limiting pressure claw 43 or the spring pressure claw 44 to move closer to or away from the welding part of the product 9. The purpose of the detachable fixed connection between the limiting pressure claw 43 or the spring pressure claw 44 and the flipping block 42 is to facilitate the replacement of different models of limiting pressure claw 43 or spring pressure claw 44. The limiting pressure claw 43 or the spring pressure claw 44 and the flipping block 42 are fixedly connected by bolts.

[0042] In one embodiment, an adjustment component is also included. The product positioning seat 2 is mounted on the base 1 via the adjustment component, which is used to adjust the vertical height and tilt angle of the product positioning seat 2.

[0043] In this embodiment, the adjustment components facilitate spot welding machine adjustment, allowing the spring height and tilt angle of each product 9 to be adjusted to a uniform height, thus improving the consistency and efficiency of machine adjustment.

[0044] In one embodiment, the adjustment component includes a first adjustment block 5, which is disposed on both sides of the product positioning seat 2. The first adjustment block 5 has at least one first slide groove 51 arranged in a vertical direction. A first slide rod 52 is disposed in the first slide groove 51. One end of the first slide rod 52 is slidably connected to the first slide groove 51, and the other end is connected to the product positioning seat 2.

[0045] In this embodiment, the first slide bar 52 is a bolt, which allows the bolt to slide up and down in the first slide groove 51 to adjust the height of the product positioning seat 2. After adjusting the height of the product positioning seat 2, the bolt is tightened to fix the product positioning seat 2 at the adjusted height.

[0046] In one embodiment, a second adjusting block 6 is provided between the product positioning seat 2 and the first adjusting block 5 on one side. The lower end of the product positioning seat 2 is hinged to the second adjusting block 6 via a rotating shaft 63. The other end of the first sliding rod 52 is connected to the second adjusting block 6. The second adjusting block 6 has an arc-shaped second sliding groove 61. A second sliding rod 62 is slidably arranged in the second sliding groove 61. A connecting block is provided on the other side of the product positioning seat 2 near the second adjusting block 6. One end of the second sliding rod 62 is slidably connected to the second sliding groove 61, and the other end is connected to the connecting block.

[0047] In this embodiment, the second slide rod 62 is also a bolt. When the second slide rod 62 slides in the second slide groove 61, the lower end of the product positioning seat 2 rotates around the rotating shaft 63, thereby achieving the purpose of adjusting the tilt angle of the product positioning seat 2. After the angle is adjusted, tightening the bolt can fix the tilt angle of the product positioning seat 2.

[0048] Meanwhile, because the second adjusting block 6 is connected to the first sliding rod 52, when the first sliding rod 52 slides, it synchronously drives the product positioning seat 2 and the second adjusting block 6 to adjust synchronously.

[0049] By setting the first adjustment block 5, the height of the spring sheet of each product 9 can be adjusted to a uniform height, which improves the consistency of machine adjustment and the efficiency of machine adjustment; the second adjustment block 6 facilitates the adjustment of the spot welding angle, reduces the need for adjusting the machine height to focus on the spring sheet welding point, and improves the efficiency of machine adjustment.

[0050] In one embodiment, the limiting claw 43 and the spring claw 44 are magnetic.

[0051] In this embodiment, by making the limiting claw 43 and the spring claw 44 magnetic, the limiting claw 43 and the spring claw 44 can be magnetically attracted to the product 9, which can further improve the pressing force of the limiting claw 43 and the spring claw 44 and prevent the spring claw 44 from not pressing in place, resulting in poor soldering.

[0052] In one embodiment, the system also includes a machine tool adapter plate 7, and the base 1 is detachably mounted on the machine tool adapter plate 7.

[0053] In this embodiment, the machine adapter plate 7 can solve the compatibility problem between the mold and the injection molding machine / die casting machine workbench, ensuring that the mold can be smoothly, accurately and safely installed on machines of different specifications or brands.

[0054] In one embodiment, positioning codes 8 are provided on both sides of the base 1, and the base 1 is clamped between the positioning codes 8 and the machine adapter plate 7.

[0055] In this embodiment, positioning brackets 8 are provided on both sides of the base 1, and the base 1 is fixed to the machine adapter plate 7 with the help of bolts.

[0056] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
