Description
Technical Field
[0001] This utility model relates to the technical field of brake pad processing equipment, and in particular to a brake disc casting riser cutting guide. Background Technology
[0002] In the brake disc casting production process, the riser is a key structure for feeding molten metal and needs to be precisely removed in subsequent processing. Traditional riser cutting relies on manual operation, which has problems such as cutting trajectory deviation and uneven cut, which can easily lead to damage to the working surface of the brake disc or dimensional deviation. Therefore, developing a guide device that can be adapted to brake discs of different specifications and realize automated and precise riser removal is of great significance for improving product quality and production efficiency.
[0003] Currently, manual operation using handheld electric cutting tools is common. Workers place the brake disc on a simple fixture, hold an angle grinder or pneumatic saw with both hands, and manually cut the riser along the outer contour of the brake disc based on experience. During the cutting process, the worker visually positions the tool and relies on arm strength to control the tool's feed trajectory and cutting depth.
[0004] However, manual operation has its drawbacks. Cutting accuracy and efficiency heavily depend on the operator's skill level. Hand tremors can easily cause the cut to deviate, resulting in riser residue or damage to the brake disc substrate, requiring secondary repairs. Furthermore, when switching between brake discs of different diameters, the workpiece position must be readjusted and the cutting path manually calibrated. Frequent positioning operations reduce production efficiency, while operating heavy hand tools increases the labor intensity of workers. Utility Model Content

The slider 23 has a through groove 25. The outer wall of the slider 22 is slidably connected to the inner wall of the groove 25. When the slider 22 moves down with the sliding sleeve 18, the groove 25 can drive the locking rod 24 to move laterally out of the saw blade 20 slot. One end of the transmission rod 17 is fitted with a spring 19, and one end of the spring 19 is fixedly connected to the inner wall of the sliding sleeve 18. The outer wall of the slider 23 is fitted with a spring 26 to provide locking force for the locking rod 24. One end of the spring 26 is fixedly connected to the outer wall of the connecting block 21. The inner wall of the moving block 13 is rotatably connected to a rotating shaft 14 to transmit rotation. The rotating shaft 14 is fixedly connected to the outer wall of an oscillating plate 15, which converts the rotation into a longitudinal oscillating motion. A metal pin 16 is slidably connected to one end of the oscillating plate 15, connecting the oscillating plate 15 and the transmission rod 17.

The lower end of the saw blade 20 rotates synchronously with the external gear ring 2 5 to ensure that the upper and lower ends of the saw blade 20 are always perpendicular.
[0029] Working principle: When this brake disc casting riser cutting guide is needed, first place the brake disc inside the machine body 1 and hold it in place by the pneumatic gripper 8. Start the motor 4 to drive the gear 3 to mesh with the external gear ring 2, causing the bridge frame 27 on the inner wall of the external gear ring 2 to rotate as a whole. At the same time, the electric telescopic rod 11 pushes the moving block 13 inside the bridge frame 27 to slide radially. The motor 3 12 on the moving block 13 drives the rotating shaft 14 to drive the oscillating plate 15 to swing. The oscillating plate 15 transmits the oscillation force to the transmission rod 17 through the metal pin 16. The sliding sleeve 18 at the end of the transmission rod 17 is under the action of the spring 19. To buffer vibration, when installing the saw blade 20, it is inserted into the sliding sleeve 18. The slider 23 inside the connecting block 21 is pushed by the spring 26, causing the locking rod 24 to slide along the sliding rod 22 and insert into the slot of the saw blade 20. The sliding rod 22 and the sliding groove hole 25 of the slider 23 cooperate to guide it. The other end of the saw blade 20 is supported by the connecting block 9 on the inner wall of the outer gear ring 25. The motor 27 drives the gear 26 to rotate the outer gear ring 25, which drives the two rollers 10 on the connecting block 19 to tension the saw blade 20. During the cutting process, the combined motion of the bridge frame 27 rotating and the moving block 13 radially feeding drives the saw blade 20 to accurately circumferentially cut the riser along the outer edge of the brake disc.
