[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0020] This utility model discloses a laser spot welding positioning device. According to the attached... Figures 1-6 As shown, the assembly includes a lower mold base 1, a lower mold 2, an upper mold base 5, and an upper mold 6. The lower mold base 1 is connected to an external component. The lower mold 2 is slidably connected inside the lower mold base 1. The upper mold base 5 is connected above the lower mold base 1. The upper mold 6 is slidably connected inside the upper mold base 5. A lower protective shell 3 is slidably connected inside the lower mold 2. An upper protective shell 7 is provided inside the upper mold 6, and the upper protective shell 7 is tightly abutted against the inner wall of the upper mold 6. Limiting components 4 are provided on both sides of the lower mold base 1. Multiple guide rods 8 are connected between the lower mold base 1 and the upper mold base 5.
[0021] Specifically disclosed, the inner walls on both sides of the lower mold base 1 are provided with spring grooves 102, and the outer walls on both sides are provided with rectangular grooves 101. A connecting rod groove 103 connects the spring grooves 102 and the rectangular grooves 101. By providing the spring grooves 102, the spring 402 and the limiting block 401 work together to facilitate the installation and removal of the lower mold 2.
[0022] Specifically disclosed, the limiting component 4 includes a limiting block 401, a spring 402, a connecting rod 403, and a rectangular locking block 404. The limiting block 401 is slidably connected in the lower mold 2. The spring 402 is slidably connected in the spring groove 102. One end of the spring 402 is rotatably connected to the limiting block 401, and the other end is fixedly connected to the bottom of the spring groove 102. The connecting rod 403 passes through the connecting rod groove 103, one end of which is fixedly connected to the limiting block 401, and the other end is fixedly connected to the rectangular locking block 404. The rectangular locking block 404 is slidably connected in the rectangular groove 101.
[0023] Furthermore, the lower mold 2 has limit holes 201 on both outer walls. The limit block 401 slides and presses against the limit hole 201. The limit block 401 is fixed by pressing against the limit hole 201, which makes the lower mold 2 easy to install and remove, improves the installation and removal efficiency, and also improves the chip welding processing efficiency.
[0024] Furthermore, the upper mold base 5 has fixing grooves 501 on both sides of the top. The upper part of the upper mold base 5 is connected to an external driving mechanism. The external driving mechanism drives the upper mold base 5 to move downward along the guide rod 8 to complete the positioning work before chip welding. At this time, laser spot welding can be performed in the hollow part of the upper mold 6.
[0025] Furthermore, the two ends of the upper mold 6 are fixedly connected to connecting blocks 601, the connecting blocks 601 are slidably connected inside the connecting blocks 601, and bolts 602 are provided above the connecting blocks 601. The bolts 602 pass through the connecting blocks 601 and are threadedly connected to the upper mold base 5.
[0026] Working principle: During installation, first determine the size of the lower mold 2 according to the chip model and size, slide the lower mold 2 into the lower mold base 1, so that the lower mold 2 abuts against the limiting block 401 until the limiting block 401 slides into the limiting hole 201, so that the lower mold 2 and the lower mold base 1 are pressed and fixed. Next, align the connecting blocks 601 on both sides of the upper mold 6 of the determined model and insert them into the fixing groove 501, tighten the bolts 602, and thread the upper mold 6 and the upper mold base 5 to fix them. Finally, slide the lower protective shell 3 into the lower mold 2 and fix the upper protective shell 7 in the upper mold 6. Then place the chip on the top of the lower protective shell 3. Through the external drive mechanism, drive the upper mold base 5 to move downward along the guide rod 8 until the upper protective shell 7 and the lower protective shell 3 can squeeze and fix the chip. At this time, laser spot welding can be performed in the hollow part of the upper mold 6.
[0027] During disassembly, pull out the rectangular blocks 404 on both sides of the lower mold 2 from the rectangular groove 101. The connecting rod 403 drives the limiting block 401 to move into the spring groove 102, and rotates the rectangular blocks 404 so that the rectangular blocks 404 press against the outside of the rectangular groove 101, thereby causing the limiting block 401 to slide out of the limiting hole 201 and be fixed in the spring groove 102, without contacting the lower mold 2. Then, remove the lower mold 2 to complete the disassembly.
[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
