Description

Technical Field

[0001] The invention relates to the technical field of slotting and grinding, and in particular to an integrated slotting and grinding device for a dust-reducing brake pad. Background Art

[0002] In various vehicles such as cars and motorcycles, as well as industrial braking equipment, brake pads are critical safety components, and their performance is directly related to the braking effect and driving safety. In the manufacturing process of brake pads, grooving and grinding are two key processes that have a decisive impact on the performance of brake pads. Grooving can effectively improve the heat dissipation performance of brake pads and avoid the degradation of braking performance due to excessive temperature during frequent braking. At the same time, grooving helps to discharge the debris and gas generated during the braking process, preventing these substances from forming a barrier between the brake pads and the brake disc, thereby ensuring the stability and reliability of braking. Dust-reducing brake pads are usually provided with grooves, including straight grooves and oblique grooves. The grinding process is designed to remove burrs and uneven parts on the surface of the brake pads, so that the brake pads and the brake disc can fit better, thereby increasing friction and improving the braking effect. At the same time, grinding can also adjust the thickness of the brake pads to ensure the dimensional consistency of the same batch of products.

[0003] At present, in the brake pad manufacturing industry, the slotting and grinding processes are mostly carried out separately and completed in sequence by different equipment. This separate processing method not only increases the complexity of the production process, but also prolongs the production cycle and increases the production cost. Therefore, it is of great significance to develop an integrated slotting and grinding device for dust-reducing brake pads. Summary of the invention

[0004] In view of the above problems, the present invention proposes an integrated grooving and grinding device for dust-reducing brake pads, and the technical solution used is: A dust-reducing brake pad slotting and grinding integrated device comprises a base, a fixed seat, a moving assembly arranged on the base to drive the fixed seat to move, a slotting assembly and a grinding assembly arranged on the base and respectively located at the middle and end of the travel of the moving assembly; The slotting assembly includes a support frame fixedly mounted on the base, a mounting frame slidably mounted on the support frame, a moving mechanism for driving the mounting frame to move, a driving shaft rotatably mounted on the mounting frame, a driving motor mounted on the mounting frame to drive the driving shaft to rotate, a middle sliding block and a side sliding block slidably mounted on the mounting frame, an adjusting screw mounted on the mounting frame to drive the middle sliding block to move, an adjusting cylinder mounted on the middle sliding block to drive the side sliding block to move, and a slotting knife slidably mounted on the driving shaft and driven to slide by the middle sliding block or the side sliding block; The grinding assembly includes a sliding frame slidably mounted on a base, a sliding cylinder mounted on the base and driving the sliding frame to move, a rotating frame rotatably mounted on the sliding frame, a rotating mechanism for driving the rotating frame to rotate, a grinding wheel rotatably mounted on the rotating frame, and a grinding motor mounted on the rotating frame and driving the grinding wheel to rotate.

[0005] Furthermore, the moving assembly includes a moving plate slidably mounted on the base, a moving screw mounted on the base and driving the moving plate to move, a moving rack fixedly mounted on a fixed seat, a moving gear meshing with the moving rack, and a moving motor mounted on the moving plate and driving the moving gear to rotate; the fixed seat is slidably mounted on the moving plate.

[0006] Furthermore, the moving mechanism includes an adjusting frame rotatably mounted on the base, and an adjusting motor mounted on the base to drive the adjusting frame to rotate; an arc-shaped slide groove is provided on the supporting frame, and the mounting frame is slidably mounted in the arc-shaped slide groove; the adjusting frame is slidably and rotatably connected to the mounting frame.

[0007] Furthermore, a worm wheel is fixedly provided on the adjusting frame, and a worm meshing with the worm wheel is fixedly installed on the output end of the adjusting motor.

[0008] Furthermore, the middle sliding block and the side sliding block are both fixedly provided with a limit frame, and the slotting knife is arranged in the limit frame; and the limit frame is rotatably provided with a toggle wheel at positions on both sides of the slotting knife.

[0009] Furthermore, the rotating mechanism includes a lifting block slidably mounted on the sliding frame, and a lifting cylinder mounted on the sliding frame to drive the lifting block to move; the lifting block is slidably and rotatably connected to the rotating frame.
