Description

Technical Field

[0001] This utility model relates to the field of drilling device technology, specifically a drilling device for heat sink processing. Background Technology

[0002] In the heat sink manufacturing process, the accuracy and efficiency of the drilling process directly affect the product quality and production cost. Traditional drilling devices mostly use fixed clamping structures, which are difficult to adapt to heat sinks of different sizes or shapes. Moreover, the clamping force is unevenly distributed, which can easily lead to displacement or deformation of the heat sink workpiece. In addition, the drilling positioning of existing equipment usually relies on manual adjustment, which has problems such as low positioning accuracy and cumbersome operation. Although some devices use electric adjustment, the multi-axis linkage structure is complex and the maintenance cost is high. Utility Model Content

[0003] The purpose of this utility model is to provide a drilling device for heat sink processing. By using multi-directional synchronous clamping of the clamping components, precise positioning driven by the cross slide, and quick installation design of the modular components, it solves the problems of unstable clamping, low positioning accuracy and inconvenient adjustment of traditional devices, and achieves efficient and high-precision automated processing.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model is a drilling device for processing heat sinks, including a base assembly, a clamping assembly, a mounting plate assembly, a drilling assembly, and four second electric push rods.

[0006] The base assembly includes a base plate, with support legs on the top of the base plate and mounting grooves fixedly connected to the bottom surface of the base plate.

[0007] The clamping assembly includes a cross frame, a first electric push rod is mounted on the bottom surface of the cross frame, a slider is fixedly connected to the output end of the first electric push rod, a clamping block is fixedly connected to the top end of the slider, and the clamping block slides through the opening of the cross frame.

[0008] The mounting plate assembly includes a mounting plate with an opening.

[0009] The drilling assembly includes a fixed plate, a cross slide is mounted on the bottom surface of the fixed plate, a motor is mounted on the sliding end of the cross slide, a coupling is fitted to the output end of the motor, and a drill rod is fitted to the bottom of the coupling.

[0010] Furthermore, it also includes four second electric actuators, the output ends of which are fixedly connected to mounting plates, and the second electric actuators are mounted on the top surface of the base plate.

[0011] Furthermore, the cross slide extends through the opening, and the bottom surface of the fixing plate overlaps the top surface of the mounting plate.

[0012] Furthermore, the outer surface of the fixing plate is fixedly connected with a hook, and the outer surface of the mounting plate is fixedly connected with a latch, with the hook and the latch being snapped together.

[0013] Furthermore, the cross frame is embedded in the support leg, and the clamping block passes through the cross frame.

[0014] Furthermore, there are four first electric push rods, sliders, and clamps, which are distributed at equal angles on the bottom surface of the cross frame.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model uses four first electric push rods evenly distributed at the bottom of the cross frame to drive the slider and clamping block to move synchronously, ensuring that the heat sink is subjected to uniform force and avoiding displacement. The four-way synchronous clamping structure enhances the fixation effect of the heat sink workpiece.

[0017] 2. The drilling assembly achieves bidirectional movement along the X and Y axes via a cross slide. Combined with a motor-driven drill rod, it can precisely adjust the drilling position, reducing manual intervention. The cross slide works in conjunction with an electric push rod to achieve fine-tuning of the drilling position.

[0018] 3. The mounting plate assembly is connected to the base via a second electric push rod, and can be raised and lowered to adapt to different heat sink workpiece heights; the fixing plate and the mounting plate are connected by hooks and latches, which facilitates quick disassembly and maintenance. The modular design simplifies the maintenance process, and the latching connection improves disassembly and assembly efficiency, adapting to the processing needs of heat sinks of various specifications.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0030] 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.

[0031] Please see Figure 1-9 This utility model provides a technical solution: a drilling device for heat sink processing, which is applied to the work of drilling heat sinks.

[0032] It includes a base assembly 1, a clamping assembly 2, a mounting plate assembly 4, a drilling assembly 5, and four second electric push rods 3. The first electric push rod 202, the second electric push rods 3, the click 503, and the cross slide 502 are all selected according to the corresponding specifications and models of the equipment as needed.

[0033] The base assembly 1 includes a base plate 101, with a support leg 102 on the top of the base plate 101 and a mounting groove 103 fixedly connected to the bottom surface of the base plate 101.

[0034] The clamping assembly 2 includes a cross frame 201. A first electric push rod 202 is mounted on the bottom surface of the cross frame 201. A slider 203 is fixedly connected to the output end of the first electric push rod 202. A clamping block 204 is fixedly connected to the top end of the slider 203. The clamping block 204 slides through the frame opening of the cross frame 201. The cross frame 201 is embedded in the support leg 102. The clamping block 204 passes through the cross frame 201. There are four first electric push rods 202, sliders 203 and clamping blocks 204, which are distributed at equal angles on the bottom surface of the cross frame 201.

[0035] The support legs 102 of the base assembly 1 provide a support platform for the heat sink workpiece. The clamping assembly 2 fixes the heat sink through a four-way synchronous clamping mechanism. The heat sink to be processed is placed on the support legs 102 of the base assembly 1, ensuring that its center is aligned with the cross frame 201. The four first electric push rods 202 are activated to push the slider 203 to slide along the guide groove of the cross frame 201, which drives the clamping blocks 204 to move synchronously towards the center of the heat sink workpiece. The four clamping blocks 204 are evenly distributed at 90° intervals to apply force, avoiding unilateral compression that could cause the heat sink workpiece to shift or deform. The clamping force is controlled by the stroke of the electric push rods to adapt to heat sink workpieces of different sizes.

[0036] The output end of the second electric push rod 3 is fixedly connected to the mounting plate 401, and the second electric push rod 3 is mounted on the top surface of the base plate 101.

[0037] Mounting plate assembly 4 includes mounting plate 401, on which a through port 402 is provided.

[0038] The drilling assembly 5 includes a fixed plate 501, a cross slide 502 is mounted on the bottom surface of the fixed plate 501, a motor 503 is mounted on the sliding end of the cross slide 502, a coupling 504 is fitted to the output end of the motor 503, a drill rod 505 is fitted to the bottom of the coupling 504, the cross slide 502 has a through-hole 402, the bottom surface of the fixed plate 501 overlaps the top surface of the mounting plate 401, a hook 6 is fixedly connected to the outer surface of the fixed plate 501, and a latch 7 is fixedly connected to the outer surface of the mounting plate 401. The hook 6 and the latch 7 are snapped together.

[0039] The quick-release design of hook 6 and latch 7 enables modular maintenance of the drilling assembly 5. By unlocking latch 7 on mounting plate 401 and detaching hook 6 from drilling assembly 5, the entire drilling assembly 5 can be removed from mounting plate 401. After disassembly, drill rod 505 can be replaced directly, motor 503 can be repaired, or cross slide 502 can be cleaned without disassembling other parts, greatly reducing downtime. After maintenance, hook 6 and latch 7 are re-engaged, and the bottom surface of fixing plate 501 is attached to the top surface of mounting plate 401 to ensure the alignment accuracy of cross slide 502 and through port 402.

[0040] Mounting plate assembly 4 and drilling assembly 5 achieve multi-axis positioning through cross slide 502 and electric push rods to ensure drilling accuracy. The mounting plate assembly 4 is driven to rise and fall by four second electric push rods 3, adjusting the vertical distance between the drill rod 505 and the surface of the heat sink workpiece to adapt to heat sinks of different thicknesses. The sliding end of cross slide 502 is controlled to move horizontally, driving motor 503 and drill rod 505 to accurately reach the target drilling coordinates. Cross slide 502 is driven by servo motor or stepper motor. When motor 503 is started, it drives drill rod 505 to rotate at high speed through coupling 504 to complete the drilling action.
