Description
Technical Field
[0001] This utility model relates to the field of brake pad processing technology, and in particular to a chamfering machine for brake pad processing. Background Technology
[0002] Automotive brake pads, also known as brake linings, are friction materials fixed to the brake drum or brake disc that rotates with the wheel. The friction linings and friction blocks withstand external pressure, generating friction to achieve vehicle deceleration. Automotive brake pads generally consist of a steel plate, an adhesive heat insulation layer, and friction blocks. The steel plate is coated to prevent rust. A chamfering machine is a specialized tool for beveling the welded front surface of pipes or plates. Chamfering machines overcome the shortcomings of flame cutting and grinding processes, such as inconsistent angles, rough surfaces, and high noise levels. They offer advantages such as ease of operation, standard angles, and smooth surfaces. They are lightweight, have a high beveling success rate, are durable, and easy to operate. They are highly suitable for welding and manufacturing fields such as steel structures, boilers, pressure vessels, equipment manufacturing, shipbuilding, power, molds, chemicals, petroleum engineering, metallurgy, heads, iron towers, and aerospace. When processing brake pads, users need to chamfer them, and a chamfering machine is required for this purpose.
[0003] In summary, traditional brake pad chamfering machines can only process brake pads of a single size, resulting in limited compatibility and hindering user experience. Therefore, a specialized brake pad chamfering machine is needed. Utility Model Content

When the rotating brake pad approaches the rotating cutting blade, efficient chamfering is achieved. The rotating fan blades blow away any debris generated during chamfering, reducing its impact on chamfering accuracy. Therefore, the user can efficiently chamfer brake pads of different sizes.

After the first telescopic rod 302 is activated, the rotating cutting blade 305 can be moved and adjusted. The user also needs to turn on the second motor 308 and the third motor 315. After the second motor 308 is activated, it can drive the fan blade 309 to rotate. After the third motor 315 is activated, it can drive the output gear 316 fixedly sleeved at the top of its output shaft to rotate. Finally, the gear transmission plate 313 can rotate. After the rotating brake plate approaches the rotating cutting blade 305, it can perform efficient chamfering. The rotating fan blade 309 can blow away the slag generated during chamfering, reducing the impact of slag on the chamfering accuracy.
