Description

Technical Field

[0001] This utility model relates to the field of drilling and tapping equipment technology, and in particular to a drilling and tapping device for brake disc processing. Background Technology

[0002] As the core load-bearing component of the automotive braking system, the brake disc's machining quality directly affects driving safety and braking stability, occupying a crucial position in the vehicle manufacturing chain. Currently, the standard machining process for brake discs in the industry requires the sequential completion of processes such as rust removal pretreatment of the blank, precision turning of both sides, machining of mounting holes and heat dissipation holes, surface grinding and anti-slip treatment, and final anti-rust spraying. Among these, the drilling step is the core link connecting turning and subsequent assembly. The machined mounting holes must accurately match the wheel hub bolt positions, while the heat dissipation holes directly affect the heat transfer efficiency during braking. If the hole position is misaligned, the hole diameter is off, or the hole wall is rough, it will not only cause the bolts to be difficult to align during assembly, but may also cause thermal deformation of the brake disc due to uneven heat dissipation during braking, resulting in safety hazards such as abnormal braking noise and brake force reduction.

[0003] Currently, brake disc drilling operations are still dominated by traditional drilling machines. These machines have several technical shortcomings in actual production: First, they have poor size adaptability. Traditional drilling machines use fixed-specification tooling and fixtures. When switching to process brake discs of different car models or diameters, it is necessary to manually disassemble the original fixtures, replace them with corresponding drill bits, and recalibrate the drilling coordinates using calipers. The entire changeover process is cumbersome and time-consuming, making it difficult to meet the flexible production needs of the automotive manufacturing industry, which involves multiple product types and rapid iterations. Second, they have low automation levels. From manual handling and clamping of brake discs to manual adjustment of the drilling machine's feed speed during drilling, efficiency is affected. Based on this, a drilling and tapping device for brake disc processing was designed. This device can work with a transfer robot to achieve automatic feeding, multi-size adaptive adjustment, and automated drilling and tapping operations, solving the problem of poor adaptability of traditional equipment during drilling operations.

[0025] It should be noted that a fixed base 320 is provided inside the housing 301, and a first sliding base 306 is movably provided on the upper part of the fixed base 320. It can move left and right under the drive of the first screw 316, thereby moving the upper second sliding base 314, the third lifting base 307, its column 315 and the tool holder 309 left and right. This design can achieve left and right movement under the drive of the third drive motor, thereby realizing the movement of the entire tool holder 309. During the machining operation, it can approach the brake disc on the rotating fixture 311 to perform the machining operation.

[0026] It should be further explained that the second sliding base 314 is movably mounted on the upper part of the first sliding base 306, and can move slightly forward under the drive of the fourth drive motor to facilitate adjustment of the drilling position; the third lifting base 307 is movably mounted inside the column 315, and can be lifted and lowered under the drive of the fifth drive motor, so that the entire tool holder 309 and drill bit 310 can be lifted and lowered. During the drilling operation, the drill bit 310 rotates rapidly inside the tool holder 309, and is lifted and lowered under the rotation of the third screw, thereby realizing the drilling operation.

[0027] like Figures 1-5As shown, the rotating clamp 311 is mounted on a first rotating shaft inside the fixed base 320, and the rotating shaft is connected to a second synchronous pulley 322 on the output shaft of the first drive motor 313 via a first synchronous pulley 321 and a synchronous belt; a three-grip chuck 312 is provided on the upper part of the rotating clamp 311; the tool holder 309 is movably mounted on a second rotating shaft of the third lifting base 307, and the second rotating shaft is connected to a second drive motor 318 via a coupling; a plurality of workpiece mounting holes are arranged in a ring on the upper part of the tool holder 309.
