Description

Technical Field

[0001] This application relates to the field of drilling equipment technology, and more specifically, it relates to a drilling auxiliary device for heat sinks. Background Technology

[0002] In the field of heat dissipation for electronic components, heat sinks are key heat conduction components, and the machining accuracy of their mounting holes directly affects the assembly efficiency and heat conduction performance of the heat dissipation module. In traditional heat sink drilling processes, operators typically use handheld electric drills to drill directly into the heat sink. However, because manual operation cannot consistently output drilling force to the electric drill, uneven force can cause the drill bit to misalign the holes. This not only increases the difficulty of fitting the heat sink to the mounting base, but in severe cases, it can even lead to loosening of the overall structure of the heat dissipation module or an increase in thermal resistance, directly affecting the heat dissipation performance and reliability of the equipment. Utility Model Content

[0003] To address the shortcomings of the existing technology, the purpose of this application is to provide a heat sink drilling auxiliary device, including a worktable on which a heat sink is placed. A fixed base is vertically formed on the back of the top of the worktable, and a movable mounting frame is provided on the front side of the fixed base. The movable mounting frame moves up and down along the side of the fixed base. An electric drill for drilling holes in the heat sink on the top of the worktable is held inside the movable mounting frame, and the electric drill moves synchronously with the movable mounting frame. An auxiliary mechanism to improve the stability of the electric drill's movement is also provided between the fixed base and the movable mounting frame. The auxiliary mechanism includes a mounting seat that moves synchronously with the movable mounting frame and is installed on the back of the movable mounting frame. A rotating shaft is horizontally inserted inside the mounting seat. Several turns of steel wire rope are wound around the outside of the rotating shaft, and the two ends of the steel wire rope are connected to the fixed base and the worktable, respectively. The rotating shaft will rub against the steel wire rope under the drive of the mounting seat, generating frictional resistance. The electric drill can apply drilling force to the heat sink smoothly along the side of the fixed base through this frictional resistance.

[0004] Preferably, the auxiliary mechanism further includes a limiting block that is movably installed on the side of the mounting base to prevent the rotating shaft from shifting laterally during lifting. The left side of the rotating shaft is elastically secured in the limiting block, and the right side of the rotating shaft is formed with a wheel for adjusting the tension of the wire rope.

[0005] Preferably, multiple sets of guide rods are installed between the fixed base and the worktable to improve the stability of the electric drill lifting, and the guide rods are respectively located vertically on the left and right sides of the front side of the fixed base, and the movable mounting frame moves in the same direction as the guide rods.

[0006] Preferably, the top of the workbench is formed with a placement groove for placing heat sinks, and the left and right sides of the heat sinks are in contact with the left and right sides of the placement grooves respectively, and the heat sinks move back and forth in the placement grooves. The top of the workbench is also formed with limiting grooves, and the limiting grooves are located on the left and right sides of the placement grooves respectively, and the limiting grooves and the placement grooves are not connected to each other.

[0007] Preferably, each of the limiting grooves is elastically provided with a limiting block to limit the top of the heat sink, and the limiting block is inserted into the limiting groove, and the limiting block moves elastically within the limiting groove.

[0008] Preferably, the bottom of the limiting pressure block is vertically and equidistantly formed with multiple protective blocks that are inserted and fitted with the heat sink.

[0009] In summary, the beneficial effects of this application are as follows:

[0010] The operator places the heat sink on top of the workbench, then positions the part of the heat sink to be drilled vertically below the drill bit. The operator then starts the drill, grips the drill handle, and lowers the drill, along with the movable mounting bracket and spindle, synchronously from the side of the fixed base until the drill bit contacts the top of the heat sink and begins drilling. During the descent, the spindle rubs against the wire rope, forming a frictional resistance system. This converts the manual feed action into controlled frictional resistance. The elastic deformation of the wire rope, combined with the spindle, buffers and stabilizes the drilling feed force, preventing problems caused by unstable drilling feed force output.

[0019] A heat sink drilling auxiliary device, see Figures 1 to 3The system includes a workbench 2 with a heat sink 1 placed on it. A fixed base 3 is vertically formed on the back of the top of the workbench 2. A movable mounting frame 4 is provided on the front side of the fixed base 3, and the movable mounting frame 4 moves up and down along the side of the fixed base 3. An electric drill 5 for drilling holes in the heat sink 1 on the top of the workbench 2 is held inside the movable mounting frame 4, and the electric drill 5 moves synchronously with the movable mounting frame 4. An auxiliary mechanism 6 is also provided between the fixed base 3 and the movable mounting frame 4 to improve the stability of the electric drill 5's movement. The auxiliary mechanism 6 includes a mounting base 601 that moves synchronously with the movable mounting frame 4, and the mounting base 601 is installed on the back of the movable mounting frame 4. A rotating shaft 602 is horizontally inserted into the mounting base 601. Several turns of steel wire rope 603 are wound around the outside of the rotating shaft 602, and the two ends of the steel wire rope 603 are connected to the fixed base 3 and the worktable 2 respectively. Under the drive of the mounting base 601, the rotating shaft 602 will rub against the steel wire rope 603 and generate frictional resistance. The electric drill 5 can use this frictional resistance to smoothly apply drilling force to the heat sink 1 on the side of the fixed base 3. In this embodiment, when the worker places the heat sink 1 on the top of the worktable 2, he only needs to position the part of the heat sink 1 to be drilled vertically below the drill bit of the electric drill 5, and then the worker can start the electric drill 5 and then hold the handle of the electric drill 5. Partially, the electric drill 5, along with the movable mounting bracket 4 and the spindle 602, descends synchronously to the side of the fixed base 3 until the drill bit of the electric drill 5 contacts the top of the heat sink 1 and begins drilling. During the descent of the electric drill 5, the spindle 602 rubs against the wire rope 603, forming a frictional resistance system. This converts manual feed into controlled frictional resistance. The elastic deformation of the wire rope 603, in conjunction with the spindle 602, buffers and stabilizes the drilling feed force, avoiding problems caused by unstable drilling feed force output from the electric drill 5. This effectively solves the problem of operators typically holding the electric drill by hand in the traditional heat sink 1 drilling process. The moving drill bit directly drills into the heat sink 1. However, because it is impossible for a person to apply a stable drilling force to the electric drill bit, the drill bit may become misaligned due to uneven force. This not only increases the difficulty of fitting the heat sink 1 with the mounting base, but may also cause the overall structure of the heat dissipation module to loosen or increase thermal resistance in severe cases, directly affecting the heat dissipation performance and reliability of the equipment. In addition, the lifting and lowering cooperation between the movable mounting bracket 4 and the fixed base 3 can form a vertical guide rail, thereby ensuring that the electric drill 5 always maintains a straight line during the lifting and lowering process, and there will be no deviation of the drill bit position, thus improving the stability of the drilling force feed.

[0020] The auxiliary mechanism 6 further includes a limiting block 604 movably mounted on the side of the mounting base 601 to prevent the rotating shaft 602 from shifting laterally during lifting. The left side of the rotating shaft 602 is elastically secured within the limiting block 604, and the right side of the rotating shaft 602 has a rotating wheel 605 formed for adjusting the tension of the wire rope 603. In this embodiment, the operator only needs to drive the rotating wheel 605 and the rotating shaft 602 to rotate within the mounting base 601 clockwise or counterclockwise, thereby changing the number of turns of the wire rope 603 around the outside of the rotating shaft 602. By changing this number of turns, the frictional resistance between the rotating shaft 602 and the wire rope 603 can be adjusted. In this embodiment, when the number of turns of the wire rope 603 around the outside of the rotating shaft 602... The more turns the wire rope 603 has around the shaft 602, the greater the frictional resistance between them. Conversely, the fewer turns the wire rope 603 has around the shaft 602, the smaller the frictional resistance between them. Therefore, this embodiment does not limit the number of turns the wire rope 603 has around the shaft 602. This number should be selected based on the actual situation on site. Furthermore, in this embodiment, the friction between the wire rope 603 and the shaft 602 is not a high-frequency action. In order to prevent the drill bit of the electric drill 5 from breaking during feeding, the electric drill 5 descends at a slow speed. Therefore, the heat generated by the friction between the wire rope 603 and the shaft 602 is negligible and will not affect the normal operation of this embodiment.

[0021] Multiple sets of guide rods 7 are also installed between the fixed base 3 and the workbench 2 to improve the lifting stability of the electric drill 5. The guide rods 7 are respectively vertically located on the left and right sides of the front side of the fixed base 3, and the movable mounting frame 4 moves in the same direction as the guide rods 7. In this embodiment, by setting the guide rods 7, the stability of the electric drill 5 during the lifting process can be improved again, which further improves the stability of this embodiment.

[0022] The top of the workbench 2 is formed with a placement groove 8 for placing the heat sink 1, and the left and right sides of the heat sink 1 are respectively in contact with the left and right sides of the placement groove 8. The heat sink 1 can move back and forth within the placement groove 8. The top of the workbench 2 is also formed with a limiting groove 9, which is located on the left and right sides of the placement groove 8, and the limiting groove 9 and the placement groove 8 are not interconnected. Each limiting groove 9 is elastically provided with a limiting block 10 to limit the top of the heat sink 1, and the limiting block 10 is inserted into the limiting groove 9. The limiting block 10 moves elastically within the limiting groove 9; the bottom of the limiting block 10 has multiple protective blocks 11 vertically and equidistantly formed to fit into the heat sink 1. In this embodiment, the bottom end of the placement groove 8 is provided with a clearance groove 12 for preventing the drill bit 5 from penetrating, and the heat sink 1 covers the top of the clearance groove 12; when the part of the heat sink 1 to be drilled is vertically below the drill bit 5, the protective blocks 11 will be inserted into the gaps between adjacent heat dissipation fins of the heat sink 1, at which time the top of the heat dissipation fin... All contact the bottom of the limiting pressure block 10. During the process of continuous and stable manual output of cutting force, the bottom of the movable mounting frame 4 will be in contact with the top of the limiting pressure block 10 and apply pressure to the limiting pressure block 10 synchronously. This drives the limiting pressure block 10 to elastically descend within the limiting groove 9 and, with the cooperation of the placement groove 8, confines the heat sink 1 within the placement groove 8. Through the cooperation of the above structures, the risk of the heat sink 1 shifting its processing position due to vibration or feed force during processing is effectively eliminated, significantly improving the drilling position accuracy. Furthermore, by providing the protective block 11, the structural deformation or collapse of the heat sink fins caused by the bottom of the movable mounting frame 4 pressing on the heat sink 1 during drilling can be effectively prevented, thereby protecting the heat sink 1 and heat sink fins and effectively improving the processing quality of this embodiment. In addition, the operator only needs to drive the heat sink 1 in the unlimited state to move forward or backward within the placement groove 8 to perform multi-position drilling on the heat sink 1, effectively improving the processing efficiency of this embodiment.

After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
