Technical Field

[0001] This utility model relates to the technical field of automotive parts processing equipment, specifically a brake disc drilling device. Background Technology

[0002] As a core component of the automotive braking system, brake discs require regularly arranged ventilation holes on their surface to achieve heat dissipation and prevent brake fade caused by high temperatures during braking. With the development of lightweight and high-performance vehicles, brake disc materials (such as cast iron and carbon fiber ceramic composites) and structures (such as perforated ventilated discs and floating brake discs) are becoming increasingly diverse, placing higher demands on the precision, efficiency, and automation of the drilling process. However, traditional brake disc drilling processes have the following limitations: 1. During the drilling process, the cutting tool is prone to wear, resulting in unstable hole diameter accuracy; 2. Manual operation is cumbersome and inefficient; 3. Drilling equipment has a complex structure and high maintenance costs; Therefore, this utility model provides a novel brake disc drilling device. Summary of the Invention

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.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0016] Example 1:

[0017] A preferred embodiment of the brake disc drilling device provided by this utility model is, for example... Figure 1-3 As shown: A brake disc drilling device includes a worktable 21, a controller 22 mounted on the front of the worktable 21, a base 23 mounted on the top of the worktable 21, a three-jaw chuck mechanism mounted on the base 23, a motor 24 mounted on one side of the worktable 21, a threaded shaft 26 fixedly connected to the output end of the motor 24, the other end of the threaded shaft 26 extending into a slide rail 25, the slide rail 25 being mounted on the top of the worktable 21, and a slider 27 threadedly connected to the threaded shaft 26 inside the slide rail 25, the slider 27 being driven to move along the slide rail 25 by the threaded shaft 26; A lifting cylinder 31 is installed on the top of the slider 27. The piston rod of the lifting cylinder 31 is connected to a mechanical arm 32. A drilling device body 33 is installed on one side of the mechanical arm 32. A drill bit is provided at the bottom of the drilling device body 33. A water tank 34 is installed on one side of the drilling device body 33. The water tank 34 is connected to a nozzle 36 through a water pipe 35. The controller 22 precisely controls the motor 24, driving the threaded shaft 26 to rotate, and the slider 27 moves accordingly. The lifting cylinder 31 drives the robotic arm 32 to precisely position, and the drill bit efficiently drills the brake disc. At the same time, the nozzle 36 sprays water mist to cool the drill bit and prevent overheating, ensuring drilling accuracy and equipment stability. This achieves automation and intelligence in the brake disc drilling process, improving production efficiency and reducing labor costs. The drill bit is equipped with a fine-tuning sensor module to precisely control the drill bit feed speed and ensure consistent hole diameter. After drilling a hole, the controller 22 precisely controls the drive motor 48 to rotate the rotating chuck 41 to a preset angle, the robotic arm 32 resets, and the slider 27 continues to move to the next drilling position. The above steps are repeated until all drilling tasks are completed.

[0018] Implementation: 2:

[0019] Please see Figures 1-3 Furthermore, based on Embodiment 1, the three-jaw chuck mechanism includes a rotating chuck 41 with three claw grooves. Retractable claws 410 are embedded in the claw grooves and their extension and retraction are controlled by a positioning cylinder 49. A connecting shaft 42 is connected to the center of the bottom of the rotating chuck 41. A bevel gear 43 is connected to the connecting shaft 42. A bevel gear 44 is meshed with the lower side of the bevel gear 43. A connecting shaft 45 is housed in the shaft core hole of the bevel gear 44. The connecting shaft 45 is fixed to the machine base 23 by a bearing seat 47. A drive motor 48 is connected to the other end of the connecting shaft 45 and is installed in the machine base 23. By starting the drive motor 48, the connecting shaft 45 is rotated, thereby causing the bevel gear 44 and the bevel gear 43 to mesh and rotate, achieving precise rotation of the rotating chuck 41. The chuck 410, under the action of the positioning cylinder 49, extends and retracts flexibly, ensuring a stable grip on the brake disc and improving drilling accuracy and efficiency. Both bevel gear 43 and bevel gear 44 are made of high-strength, wear-resistant materials. The drive motor 48 is equipped with an overheat protection device to ensure stable operation over long periods. The positioning cylinder 49 employs precision sealing technology to prevent air leakage and ensure the chuck can extend and retract freely.

[0020] A clamp 411 is fixedly installed on the top of the chuck 410. The clamp 411 has a built-in air nozzle 412, which is connected to an air source through an external air pipe. When drilling holes in the brake disc, the generated debris is quickly blown away from the working area through the air nozzle 412, preventing accumulation and affecting operating accuracy.

[0021] In use, the controller 22 starts the motor 24 to drive the threaded shaft 26 to rotate, which in turn drives the first bevel gear 43 to rotate and the second bevel gear 44 to rotate synchronously. The chuck achieves precise rotary motion, and the speed can be steplessly adjusted within the range of 50-2000 rpm by the frequency converter.

[0022] Positioning cylinder 49 pushes chuck 410 to retract radially, forming a uniform clamping force on the outer edge of the brake disc; external air source supplies air to nozzle 412 through quick-connect connector, forming an annular air curtain during chuck rotation, which removes iron filings generated during drilling in real time. The waste chips fall into the water tank circulation filtration system with the airflow. The operator manually adjusts the angle of the universal bamboo joint tube, and nozzle 36 is aimed at the contact area between the drill bit and the workpiece. The water tank pump delivers coolant, forming a directional jet flow, which reduces drilling temperature and washes away residual chips. The coolant is recycled after being treated by a magnetic separator.
