The guard plates are provided in two pieces and are respectively welded to the middle and rear ends of the upper part of the frame. A pad is welded to the front end of the upper part of the frame. The first pressure roller and the second pressure roller are installed between the two guard plates. A first bearing is installed in the guard plates on both sides of the first pressure roller. A screw passes through the first bearing and is installed in the first pressure roller. A first gear is installed at the front end of the screw on the left side of the first pressure roller. A slot is provided in the middle of the screw. A second bearing is installed in the guard plates on both sides of the second pressure roller. A motor shaft is installed in the second bearing and passes through the second pressure roller. A second gear is installed on the left side of the motor shaft. The first gear and the second gear are meshed together.

[0004] Some problems were found when using the existing heat sink processing leveling machine. First, the roller extrusion method is only suitable for leveling single heat sinks and cannot level heat sink stacks (fins). Directly leveling the fins will aggravate the problem of bending angle.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 This utility model provides a technical solution: a welding machine heat sink stacking and leveling device, including a base 1, brackets 2 fixedly connected to both sides of the base 1, an electric telescopic rod 201 fixedly connected to the bottom of the brackets 2, a snap-fit ​​connector 3 fixedly connected to the lower end of the electric telescopic rod 201, a first fixing hole 301 fixedly connected to the lower end of the snap-fit ​​connector 3, a connecting seat 702 snapped onto the first fixing hole 301, a fixing plate 7 fixedly connected to the bottom of the connecting seat 702, a plurality of leveling comb teeth 701 fixedly connected to the bottom of the fixing plate 7, a processing slide 5 slidably connected to the base 1, a fixed clamping block 504 fixedly connected to the processing slide 5, a vertically opening limit groove 501 on the processing slide 5, a limit slider 601 slidably installed in the limit groove 501, a sliding clamping block 6 fixedly connected to the limit slider 601, and the sliding clamping block 6 and the fixed clamping block 504 cooperating with each other.

[0024] In this embodiment, during use, the heat sink is placed on the processing slide table 5, between the sliding clamping block 6 and the fixed clamping block 504. The limiting slider 601 is slidably installed inside the limiting groove 501, allowing the limiting slider 601 to move back and forth within the limiting groove 501. The movement of the limiting slider 601 drives the sliding clamping block 6 to move, adjusting the distance between the sliding clamping block 6 and the fixed clamping block 504. The sliding clamping block 6 and the fixed clamping block 504 can clamp and fix the heat sink on the processing slide table 5. During clamping, care should be taken to align the fin grooves of the heat sink with the leveling comb teeth 701. Activating the electric telescopic rod 201 can drive the connecting seat 702 downward through the snap-fit ​​connector 3. The downward movement of the connecting seat 702 can... The fixing plate 7 is moved downwards, which allows the leveling comb teeth 701 to be inserted into the fin grooves of the heat sink. The lower end of the leveling comb teeth 701 is chamfered, so that it can be inserted into the inclined fin gaps. As the leveling comb teeth 701 are fully inserted into the stack and fins of the heat sink, the heat sink stack can be leveled, keeping the heat sink stack in a vertical state. When the upper end of the heat sink fins is completely inclined and attached together, it can be kept in a normal position from the front or rear end. The processing slide 5 is used to move the clamped heat sink forward or backward, so that the leveling comb teeth 701 are inserted from the normal position in front or behind the heat sink fins. As the heat sink is moved forward or backward, the bent parts of the heat sink fins are leveled.

[0025] To achieve the purpose of moving the machining slide 5 back and forth, the device adopts the following technical solution: T-shaped slots 101 are symmetrically opened on the base 1, and T-shaped sliders 508 are symmetrically fixed to the bottom of the machining slide 5. The T-shaped sliders 508 slide in cooperation with the T-shaped slots 101. A connecting groove 102 is opened on the base 1, and a threaded screw 103 is rotatably installed in the connecting groove 102. An adjusting motor 104 is fixed to the rear of the base 1, and the output end of the adjusting motor 104 is fixed to the threaded screw 103. A connecting slider 506 is fixed to the bottom of the machining slide 5, and a threaded hole 507 is opened in the connecting slider 506. The threaded hole 507 is threaded in cooperation with the threaded screw 103.

[0026] The T-slot 101 and the T-slider 508 are slidably engaged to connect the machining slide 5 to the base 1. The length of the T-slider 508 is less than that of the T-slot 101, so the T-slider 508 can slide back and forth a certain distance inside the T-slot 101, allowing the machining slide 5 to slide back and forth on the base 1. Starting the adjusting motor 104 can drive the threaded screw 103 to rotate. The threaded screw 103 is threadedly engaged with the threaded hole 507, so the rotation of the threaded screw 103 can drive the connecting slider 506 to move. The movement of the connecting slider 506 can drive the machining slide 5 to move. The adjusting motor 104 drives the machining slide 5 to move back and forth.

[0027] To achieve the purpose of fixing the fixing plate 7, the device adopts the following technical solution: A threaded through hole 4 is opened on one side of the bracket 2, and an adjusting threaded rod 401 is installed in the threaded through hole 4. A positioning block 402 is rotatably installed at one end of the adjusting threaded rod 401. A scale 505 is engraved on the processing slide table 5. An adjusting screw 502 is installed in the threaded limit slide groove 501. A rotating disk 503 is fixed to the front end of the adjusting screw 502. A threaded connection hole is opened in the limit slider 601. The threaded connection hole is threadedly engaged with the adjusting screw 502. A first fixing hole 301 is opened in the snap-fit ​​connector 3. A snap-fit ​​groove 703 is opened on the connecting seat 702. The snap-fit ​​connector 3 is snapped into the snap-fit ​​groove 703. A second fixing hole 704 is opened in the connecting seat 702. A fixing pin 8 is set in the second fixing hole 704. The fixing pin 8 cooperates with the second fixing hole 704 and the first fixing hole 301.

[0028] The threaded rod 401 is installed inside the threaded through hole 4, and the positioning block 402 is attached to the machining slide 5, thereby restricting the rotation of the threaded through hole 4. Rotating the threaded rod 401 can move the positioning block 402. The positioning block 402 cooperates with the scale 505, and the position of the positioning block 402 can be quickly determined using the scale 505. The positioning block 402 can abut against the outer wall of one side of the heat sink to position the heat sink, so that the gap between the heat sink fins is aligned with the leveling comb teeth 701. At the same time, in order to avoid interference between the positioning block 402 and the fixed clamping block 504, when the machining slide 5 needs to move back and forth, the positioning block 402 needs to be moved to the outermost side. The rotating disk 503 can drive the adjusting screw 502 to rotate. The adjusting screw 502 cooperates with the threaded connection hole, and the rotation of the adjusting screw 502 can drive the limit slider 601 to move. The movement of the limit slider 601 can then drive the sliding clamping block 6 to move and clamp the heat sink. After the snap-fit ​​connector 3 is snapped into the snap-fit ​​groove 703, the fixing pin 8 is inserted into the second fixing hole 704 and the first fixing hole 301 to fix the snap-fit ​​connector 3 in the snap-fit ​​groove 703. After unscrewing the fixing pin 8, the connecting seat 702 can be directly separated from the snap-fit ​​connector 3, which is convenient for later replacement of the corresponding fixing plate 7 and the leveling comb teeth 701 according to the model of the heat sink and the fin spacing.

[0029] The working principle and usage process of this utility model are as follows: During use, the heat sink needs to be placed on the processing slide table 5, between the sliding clamping block 6 and the fixed clamping block 504. Rotating the adjusting screw 502 causes the sliding clamping block 6 to move backward. The sliding clamping block 6 and the fixed clamping block 504 cooperate to clamp and fix the heat sink. During clamping, it is important to ensure that the gap between the heat sink fins is aligned with the leveling comb teeth 701. Then, the electric telescopic rod 201 is activated to move the fixing plate 7 downward. The downward movement of the fixing plate 7 will move the leveling comb teeth 701. Inserting the fins into the gaps between the heat sink fin stacks allows for the leveling of the heat sink stacks. When the upper ends of the heat sink fins are completely tilted and attached together, the normal position can be maintained from the front or rear end. The adjusting motor 104 drives the processing slide 5 to move the clamped heat sink forward or backward, so that the leveling comb teeth 701 are inserted from the normal position in front of or behind the heat sink fins. As the heat sink is moved forward or backward, the bent parts of the heat sink fins are leveled, so that the heat sink stacks are in a flat and vertical state.
