Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat dissipation fin processing, and in particular to a deburring device for heat dissipation fins. Background Technology
[0002] Heat sinks are widely used heat dissipation components in electronic devices. They typically consist of a series of parallel and equally spaced metal sheets connected together by some means (such as welding, riveting, or integral molding) to form a single structure. During the processing of heat sinks, burrs are generated at the bottom of the grooves between the sheets. Currently, the removal of these burrs is mostly done manually by using files to smooth the bottom of the grooves. This method is time-consuming and labor-intensive, and it is easy to have incomplete cleaning, resulting in defective products. Therefore, it is not suitable for mass production and processing. Utility Model Content
[0003] To address the aforementioned problems, this utility model provides a deburring device for heat dissipation fins, which has a simple structure, can improve deburring efficiency, reduce human error, and ensure a high yield rate.
[0004] The technical solution of this utility model is:
[0005] A deburring device for heat dissipation fins includes a worktable, an elongated working track on the upper surface of the worktable, a cutting groove through the worktable and arranged along the length axis of the working track, a deburring blade in the cutting groove, and a drive mechanism connected to the deburring blade on the lower surface of the worktable. The deburring blade extends out of the upper surface of the worktable. Positioning plates are symmetrically arranged at both ends of the working track along its length. The symmetrically arranged positioning plates and the working track have a U-shaped cross-section. A pressure roller is arranged above the length axis of the working track. The rotation direction of the pressure roller is parallel to the length direction of the working track. A pressure rod is coaxially fixedly connected to the center of the pressure roller. The pressure rod is connected to one of the positioning plates and the pressure rod and the positioning plate are connected by a screw.
[0006] Furthermore, a buffer spring is provided between the screw and the pressure rod, and the buffer spring is coaxially sleeved on the screw.
[0007] Furthermore, a height adjustment mechanism is provided between the drive mechanism and the worktable.
[0008] Furthermore, a guide ridge is provided on one side of the working track along its length axis.
[0009] Furthermore, the number of guide protrusions is three.
[0010] Furthermore, the pressure roller is a rubber roller.
[0011] The beneficial effects of this utility model are:
[0012] 1. By setting a working track on the workbench, a pressure roller is set above the working track, and a deburring knife is set below. The heat sink fins to be deburred are continuously pushed in along the working track. The pressure roller ensures that the heat sink fins are kept in a stable position for deburring. The deburring knife accurately deburrs the heat sink fins in one go, which can eliminate human error and improve work efficiency.
[0013] 2. The drive mechanism connected to the deburring blade is height-adjustable, allowing for flexible adjustment of the deburring depth according to different models of heat sink fins. Combined with the pressure rod and pressure roller, it ensures the reliability and safety of the deburring operation.
[0014] 3. The working track is equipped with guide ridges to ensure that the heat sink fins to be deburred will not be deflected when entering the track, thus ensuring the reliability of the deburring operation. Attached Figure Description

Detailed Implementation
[0022] The embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0023] Example:
[0024] like Figures 1-5As shown, a deburring device for heat dissipation fins includes a worktable 1, a long strip-shaped work track 2 disposed on the upper surface of the worktable 1, a cutting groove 3 disposed within the work track 2 and disposed along the length axis of the work track 2, penetrating the worktable 1, a deburring knife 4 disposed in the cutting groove 3, and a drive mechanism 5 disposed on the lower surface of the worktable 1 and connected to the deburring knife 4. The deburring knife 4 extends out of the upper surface of the worktable 1. Positioning plates 21 are symmetrically arranged at both ends of the length direction of the work track 2. The symmetrically arranged positioning plates 21 and the work track 2 have a U-shaped cross section. A pressure roller 6 is disposed above the length axis of the work track 2. The rotation direction of the pressure roller 6 is parallel to the length direction of the work track 2. A pressure rod 7 is coaxially fixedly connected to the center of the pressure roller 6. The pressure rod 7 is connected to one of the positioning plates 21. The pressure rod 7 and the positioning plate 21 are connected by a screw 8.
[0025] The working principle of the above technical solution is as follows:
[0026] The heat sink fins 10 to be deburred are placed sequentially on the working track 2 set on the workbench 1. The left and right positions are restricted by the positioning plate 21, and the top surface of the heat sink fins is fixed by the pressure roller 6. The deburring knife 4 under the workbench 1 extends into the working track through the knife groove 3. The drive mechanism 5 is activated to drive the deburring knife 4. As the heat sink fins 10 pass through the deburring knife 4 in sequence, the heat sink fins 10 can be deburred precisely, which can significantly improve the work efficiency and work accuracy. The position and number of deburring knives 4 can be flexibly adjusted according to the heat sink fins 10 to be deburred. The pressure roller 6 is connected to the positioning plate 21 through the pressure rod 7, and the position of the pressure roller 6 is fixed by the screw 8, which can prevent the heat sink fins 10 from being deburred during the deburring operation.
[0027] A buffer spring 9 is installed between the screw 8 and the pressure rod 7. The buffer spring 9 is coaxially sleeved on the screw 8. The buffer spring 9 can effectively reduce the vibration caused by cutting burrs and improve the reliability and safety of the operation.
[0028] A height adjustment mechanism is provided between the drive mechanism 5 and the worktable 1, which can flexibly adjust the height of the drive mechanism 5 and thus the height of the deburring knife 4 according to the heat dissipation fins of different sizes and specifications.
[0029] The working track 2 is provided with three guide ridges 22 along one side of its length axis. The spacing between the guide ridges 22 is consistent with the fin spacing of the heat dissipation fins 10 to be deburred. The multiple guide ridges 22 can ensure that the heat dissipation fins 10 will not be misaligned in the working track 2, thus ensuring the reliability of the operation.
[0030] The pressure roller 6 is a rubber roller, which can act as a pressure block without damaging the surface of the workpiece, thus improving the safety of the operation.
[0031] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
