DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1 、 2 The utility model provides a deburring tool, including a bracket 1, a plurality of scrapers 2 slidably arranged on the bracket 1, and two pressing mechanisms 3 for pressing the ends of all the scrapers 2. The upper part of the scraper 2 is provided with more than two triangular parts 21, and the side edges of the triangular parts 21 scrape away the burrs on the radiating fins of the radiator. The thickness of the scraper 2 is greater than the distance between two adjacent radiating fins.

[0024] In actual use, the position of each scraper 2 is adjusted according to the position of each heat dissipating fin a1 on the radiator a, and the position of all scrapers 2 is fixed by the clamping mechanism 3. When deburring, the radiator is placed on the scraper 2 so that the scraper 2 is spaced apart from the heat dissipating fin. First, one side of the heat dissipating fin is pressed against one side of the scraper 2, and then the radiator is pushed forward and backward so that one side of the heat dissipating fin contacts the side of the scraper 2, thereby scraping off the burrs; then the other side of the heat dissipating fin is pressed against one side of another scraper 2, and similarly, the radiator is pushed forward and backward to scrape off the burrs on the other side of the heat dissipating fin. Since the thickness of the scraper 2 is greater than the distance between two adjacent heat dissipating fins, in the above two operations, the top of the triangular portion 21 on the scraper 2 can scrape off the burrs on the lower surface of the radiator. Compared with the existing technology, the radiator can be quickly removed by pushing it back and forth with two wheels, and the work efficiency is high.

[0025] In the above description, the burrs on the lower surface of the radiator are caused by drilling holes in the radiator, leaving uneven burrs on the lower surface of the radiator.

[0026] In a preferred embodiment, see Figure 2 The clamping mechanism 3 includes a guide rod 31 vertically arranged on the bracket 1, a pressure strip 32 slidably connected to the guide rod 31, and a spring 33 sleeved on the guide rod 31. The spring 33 is used to press the pressure strip 32 downward to fix the position of all scrapers 2; the two guide rods 31 are symmetrically arranged on the bracket 1. Under the action of the spring 33, the pressure strip 32 is pressed against the scraper 2, which plays a role of pre-positioning the scraper 2. When adjusting the position of the scraper 2, due to the elasticity of the spring 33, the scraper 2 only needs to be moved with a little force to move the scraper 2, thereby achieving the purpose of moving the scraper 2.

[0027] The pressure strip 32 is provided with a locking screw 34 that passes through the bracket 1. A locking nut 35 is threaded onto the locking screw 34. Two locking screws 34 are symmetrically located on the bracket 1 and are located outside the two guide rods 31. After the position of each scraper 2 is adjusted, the locking nuts 35 are tightened to further tighten the pressure strip 32 against all scrapers 2, ensuring the installation stability of the scrapers 2.

[0028] Preferably, the locking nut 35 is a butterfly nut, so that the operator can loosen or tighten the adjustment nut. In addition, since the locking nut 35 is positioned at the lower surface of the support 1, there is no position interference with the guide rod 31 during operation, and the operation is flexible.

[0029] Further, see Figure 2 The end of the scraper 2 is provided with an outward-extending flange 22, which is located between the pressure strip 32 and the bracket 1, so that the clamping mechanism 3 can clamp and fix the entire scraper 2; and the flange 22 extends to the outside of the side of the pressure strip 32 and the bracket 1, that is, the flange 22 protrudes outside the pressure strip 32 and the bracket 1, so that the operator can clamp the flange 22 to adjust the position of the scraper 2.

[0030] In a preferred embodiment, see Figure 1 , further comprising a scale 4 for easily checking the position of the scraper 2. A slope 11 is provided on the side of the bracket 1 near the clamping mechanism 3. The scale 4 is located on the slope 11, making it easier for the operator to adjust the position of each scraper 2 using the scale 4. Preferably, the numerical markings on the scale 4 extend to the top surface of the bracket 1, that is, part of the numerical markings are located where the flange 22 contacts the bracket 1, further facilitating determination of the position of the scraper 2.

[0031] In a preferred embodiment, see Figure 2 A groove 12 is provided on the upper surface of the bracket 1, and a sliding portion 23 is provided at the bottom of the scraper 2, which is slidably connected to the groove 12, that is, the length of the sliding portion 23 is consistent with the length of the groove 12, and the sliding portion 23 moves horizontally along the width direction of the groove 12 to adjust the position of the scraper 2, and the scraper 2 is not easy to deviate during adjustment.

[0032] In a preferred embodiment, see Figure 2 A horizontal surface 211 is provided on the top of each triangular portion 21 to increase the contact area between the triangular portion 21 and the lower surface of the radiator, thereby preventing the triangular portion 21 from being too sharp and scratching the radiator, and preventing the operator from being scratched when touching the triangular portion 21.

[0033] In a preferred embodiment, see Figure 2In order to further speed up the adjustment of the position of each scraper 2, a pre-positioning block 5 is also included. The pre-positioning block 5 is slidably arranged on the bracket 1. The pre-positioning block 5 is used to locate the position of the radiator so as to facilitate the adjustment of the position of each scraper 2. When in use, first place the radiator on the scraper 2, and multiple scrapers 2 are spaced apart from multiple heat dissipation fins, such as Figure 3 As shown, first, the heat dissipation fin on the far right is brought into contact with the scraper 2 on the far right, and then the position of the pre-positioning block 5 is adjusted to push the radiator toward the scraper 2. Next, the position of each scraper 2 is adjusted to make the right side of the remaining heat dissipation fins contact the left side of the corresponding scraper 2. Finally, as shown in FIG. Figure 4 As shown, remove the pre-positioning block 5 and move the radiator to the left by one position, so that the left side of the heat dissipating fin contacts the right side of the other corresponding scraper 2. At this time, adjust one scraper 2 to contact the heat dissipating fin on the far left. In this way, the function of quickly adjusting the position of the scraper 2 is realized.

[0034] It should be noted that after removing the predetermined block 5, a new scraper 2 needs to be added to the bracket 1 to serve as the scraper 2 that contacts the leftmost heat sink fin. When adding the scraper 2, first tilt the scraper 2 so that its two flanges 22 are inserted between the two pressure strips 32 and the bracket 1, and then vertically straighten the scraper 2. This operation is simple.

[0035] Further, see Figure 2 An adjustment groove 13 is provided on the groove 12, and the pre-positioning block 5 is slidably connected to the adjustment groove 13. A slider 51 is provided on the pre-positioning block 5 and is slidably connected to the adjustment groove 13. The slider 51 is connected to a set screw 52 that moves along the adjustment groove 13. Specifically, the pre-positioning block 5 is an L-shaped structure, and the slider 51 is located at the bottom of the pre-positioning block 5. The set screw 52 on the slider 51 moves along the adjustment groove 13. By screwing in or out the set screw 52, ​​the position of the pre-positioning block 5 can be quickly adjusted.

[0036] Preferably, the set screw 52 is a screw with a plum blossom handle to facilitate operation by the operator.

[0037] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and the utility model concept of the present invention, and all these changes or substitutions should fall within the scope of protection of the present invention.
