DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0026] Embodiment one

[0027] The utility model embodiment provides a kind of SMT patch welding positioning device.

[0028] Please refer to Figure 1 、 Figure 2 、 Figure 3 And Figure 4The device includes a positioning fixture body 1, which is the main body of the positioning device. Mounting brackets 15 are fixed at each of the four corners of the positioning fixture body 1. The mounting brackets 15 can be bolted to the positioning fixture body 1 using pre-drilled holes 16. Each mounting bracket 15 has a pre-drilled hole 16 in its center. A sliding groove 2 is formed in the center of the positioning fixture body 1. Sliding sliders 3 are slidably connected to the inner walls of both sides of the sliding groove 2. Two bidirectional threaded rods 4 are threadedly connected to the center of the two sliding sliders 3. Rotary handles 5 are fixed to both ends of the bidirectional threaded rods 4. The outer surfaces of the two sliding sliders 3 are slidably connected to the sliding groove 2. The inner walls on both sides of the groove 2 are connected by two sliders 3 to the outer surfaces of the two sides of the bidirectional threaded rod 4. The outer surfaces of the bidirectional threaded rod 4 are rotatably connected to the middle of the positioning fixture body 1. The middle of the two rotating handles 5 is fixed to both ends of the bidirectional threaded rod 4. The two sliders 3 are provided with a connecting structure, which includes four first frames 6 and two connecting frames 8. One of the first limiting frames 7 is fixed at one end of each pair of adjacent first frames 6. The two connecting frames 8 are rotatably connected to the two disjoint ends of each other. The two second frames 9 are fixed to the two disjoint ends of each other.

[0029] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 It is worth noting that the near ends of each pair of first frames 6 are fixed to the far ends of the two sliders 3, and the far ends of each pair of first frames 6 are fixed to the far ends of the two first limiting frames 7. Each first limiting frame 7 passes through one side of the slide groove 2, and the vertical cross-section of each first limiting frame 7 is U-shaped. The outer surface of each first limiting frame 7 is slidably connected to the upper surface of one side of the positioning fixture body 1. The near ends of the two connecting frames 8 are rotatably connected to the far ends of the two sliders 3. The far ends of the two connecting frames 8 are rotatably connected to the near ends of the two second frames 9. The two second frames 9 pass through both sides of the slide groove 2 and are staggered. The outer surfaces of the two second limiting frames 10 are slidably connected to the upper surfaces of both sides of the positioning fixture body 1.

[0030] In use, this invention involves manually rotating the handle 5. Under the limiting constraint of the positioning fixture body 1, the bidirectional threaded rod 4, fixedly connected to the handle 5, begins to rotate. As the bidirectional threaded rod 4 rotates, two sliders 3 connected by threads on its outer surfaces slide in opposite directions under the guidance and limiting action of the sliding groove 2. These two opposing sliding sliders 3 drive the two sets of first frames 6, fixedly mounted on their respective opposite sides, to slide synchronously in the opposite direction. These two sets of opposing sliding first frames 6 further drive the first limiting frame 7 fixed at its opposite end to slide in the opposite direction. Simultaneously, the two sliders 3, through two connecting frames 8 rotatably connected at their opposite ends, push the two second frames 9 to slide in the opposite direction under the limiting action of the positioning fixture body 1. These two opposing sliding second frames 9 drive the second limiting frame 10 fixed to them to slide in the opposite direction. It is worth noting that the two first limit frames 7 and the two second limit frames 10 will move away from each other or move closer to each other simultaneously. In this way, the multi-point limit function can be realized according to the specific size of the workpiece, so as to achieve the effect of multi-point limit on workpieces of different sizes. This allows the positioning device to be adapted to workpieces of different sizes and specifications, thereby improving the versatility of the positioning device.

[0031] Example 2

[0032] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 Based on Embodiment 1, a workpiece lifting function has been added;

[0033] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 It is worth noting that the positioning fixture body 1 has a storage groove 11 in the middle, and a stabilizing groove 12 is provided on the lower side of the storage groove 11. A drive frame 13 is slidably connected to the inner wall of the stabilizing groove 12. A lifting frame 14 is fixed in the middle of the drive frame 13. The outer surface of the lifting frame 14 is slidably connected to the inner wall of the storage groove 11. The outer surface of the drive frame 13 is slidably connected to the inner wall of the stabilizing groove 12. The inclined surfaces at both ends of the drive frame 13 are in contact with the outer surfaces of the two sliders 3 on their opposite sides.

[0034] In use, this invention involves manually rotating the handle 5 to initiate rotation of the bidirectional threaded rod 4, which is fixedly connected to the handle 5. During rotation, the bidirectional threaded rod 4 drives two sliders 3, which are threadedly connected to its outer surfaces. Due to the limiting effect of the sliding groove 2, these two sliders 3 slide away from each other. As the two sliders 3 move away from each other, they exert a squeezing effect on the inclined surface of the inner wall of the drive frame 13, which is slidably connected to the stabilizing groove 12. Under the limiting constraint of the stabilizing groove 12, the drive frame 13 moves upward. Simultaneously, the lifting frame 14, which is fixedly connected to the drive frame 13, moves upward synchronously with the drive frame 13 under the limiting effect of the receiving groove 11. The upward-moving lifting frame 14 performs a lifting operation on the already processed workpiece, effectively increasing the gap between the workpiece and the positioning fixture. This increased gap provides more operating space for workers to handle the workpiece, significantly improving the convenience of handling and thus enhancing the ease of use of the positioning device.
