Description

Technical Field

[0001] The present invention relates to the technical field of brake disc processing, in particular to a brake disc processing lathe. Background Art

[0002] Brake discs (also known as brake discs) are a core component of a vehicle's braking system. They convert the vehicle's kinetic energy into heat through friction with the brake pads, thereby achieving deceleration and stopping. During the brake disc manufacturing process, to ensure a smooth, flat surface and meet precision requirements, the discs are typically turned on a lathe. Furthermore, heat dissipation holes are machined into the disc surface. To improve production efficiency and reduce workpiece transfer, existing lathes are equipped with a mechanism for drilling the discs, referred to as integrated turning and drilling lathes.

[0003] The brake disc's surface has multiple groups of cooling holes arranged in a circular array around the center of the disc. Each group contains multiple holes, for example, four.

The spring 38 is slidably sleeved on the outer wall of the pillar 36, and a clamping component is provided on the outside of the pillar 36.

[0039] In this embodiment, first, the brake disc body 10 is fixed to the middle of the upper end of the electric turntable 5 from the inner side of the brake disc body 10 using the existing centering fixture. At this time, the center of the brake disc body 10 corresponds to the center of the electric turntable 5 and the annular electric slide 12. Then, the electric turntable 5 is started to drive the brake disc body 10 to rotate at high speed. By starting the electric slide 18, the electric push rod 2 9 and the turning tool 11 can be driven to move upward or downward. By starting the electric push rod 2 9, the turning tool 11 can be driven to move toward the brake disc body 10 or away from the brake disc body 10. Then, the turning tool 11 can perform a turning operation on the upper surface of the brake disc body 10. After the operation is completed, the electric turntable 5 is turned off and the turning tool 11 is withdrawn.

[0040] The four drill bits 14 first form an arc shape, and the centers of the four drill bits 14 are all on an arc line (such as Figure 9As shown in the figure, starting the motor 15 can drive the stud 25 to rotate, and the stud 25 can drive the slider 28 to move in the direction of the housing 17, and the slider 28 will also slide on the outer wall of the guide column 32, and the slider 28 can also drive the two connecting rods 16 to rotate outward synchronously, and the two connecting rods 16 can drive the U-shaped plates 22 connected to them to rotate on the corresponding U-shaped blocks 21, and the two U-shaped plates 22 have opposite directions. The two U-shaped plates 22 can drive the fixed blocks 18, small electric push rods 20, convex blocks 19, U-shaped blocks 23, motors 14 and drill bits 14 connected to them to rotate together. The two drill bits 14 in the middle of the four drill bits 14 do not move, while the two drill bits 14 at the edge will rotate, so that the curvature of the arc formed by the four drill bits 14 can be adjusted, and the two drill bits 14 at the edge can also be rotated until the centers of the four drill bits 14 are in a straight line.

[0041] Starting the motor 2 31 can drive the bidirectional screw 30 to rotate, and the bidirectional screw 30 can drive the two slides 26 to slide away from each other inside the housing 17. The two slides 26 can drive the U-shaped blocks 21 connected to them to move together. The two U-shaped blocks 21 can drive the motor 1 4 and the drill 14 connected to them to move together. The two U-shaped blocks 21 can also drive the U-shaped plates 22 connected to them to move together, and the two U-shaped plates 22 are moving away from each other, which will cause the two connecting rods 16 to move away from each other. Each connecting rod 16 will drive the L-shaped plate 29 to move away from the slider 28, and each slider 28 will drive the pillars 36 connected to them to slide in the corresponding support blocks 35, and each pillar 36 will drive each The self-connected connecting disk 37 squeezes the corresponding spring 38. At the same time, the two small electric push rods 20 are started. The two small electric push rods 20 can drive the respectively connected convex blocks 19 to slide in the corresponding slide groove 27 away from the corresponding U-shaped plate 22. The two convex blocks 19 can drive the respectively connected U-shaped blocks 23 to move together, and the two U-shaped blocks 23 are in a state of moving away from each other. The two U-shaped blocks 23 can drive the respectively connected motors 4 and the drills 14 to move together, so the drills 14 under the two U-shaped blocks 23 are also in a state of moving away from each other, and the drills 14 under the two U-shaped blocks 21 are also in a state of moving away from each other. Then, among the four drills 14, the distance between each adjacent two drills 14 will be synchronously expanded.

[0042] By starting the electric slide 2 13, the electric push rod 1, the fixed plate 2, the four drill bits 14 and other components connected to the fixed plate 2 can be driven to move left or right together. Then, the left and right positions of the four drill bits 14 can be adjusted so that the four drill bits 14 are centered and correspond to the annular area where the heat dissipation holes are required to be opened on the brake disc body 10. By starting the electric push rod 1, the fixed plate 2, the four drill bits 14 and other components connected to the fixed plate 2 can be driven to move downward together. By starting the four motors 14, the four drill bits 14 can be driven to rotate synchronously, so that the brake disc body 10 can be adjusted. Four heat dissipation holes are opened at one time in the annular area of ​​the brake disc body 10 where heat dissipation holes are required, and four heat dissipation holes form a group. Then, the fixed plate 2, four drill bits 14 and other components connected to the fixed plate 2 are driven to move upward together by the electric push rod 1, and then the annular electric slide 12 is started to drive the electric slide 2 13, the electric push rod 1, the fixed plate 2, the four drill bits 14 and other components connected to the fixed plate 2 to rotate together. Then, multiple groups of heat dissipation holes can be opened in a circular array in the annular area of ​​the brake disc body 10 where heat dissipation holes are required.

[0043] To sum up, the arrangement of the four drill bits 14 can be changed, that is, the centers of the four drill bits 14 can be on a straight line or on an arc, and the centers of the four drill bits 14 can be on arcs of different radians, and the distance between each two adjacent drill bits 14 in the four drill bits 14 can be adjusted synchronously, so the requirements for opening heat dissipation holes of different brake disc bodies 10 can be met, and the four drill bits 14 can open a group of heat dissipation holes on the surface of the brake disc body 10 at one time, so compared with the traditional single drill to open heat dissipation holes one by one, the flexibility, adaptability and efficiency of drilling are improved.

[0044] Example 2: Please refer to Figure 7 and Figure 8 This embodiment further explains Example 1. The clamping assembly includes a mounting column 41, which is fixedly connected to the upper end of the slider 28 near the support block 35. The top of the mounting column 41 is fixedly installed with a motor three 34, and the output shaft end of the motor three 34 is fixedly connected with a bidirectional screw 40. The lower end of the bidirectional screw 40 is rotatably connected to the upper end of the slider 28. The outer wall of the bidirectional screw 40 is symmetrically threaded with a splint 33. The two splints 33 are respectively located above and below the pillar 36. The two splints 33 are both in contact with the vertical wall of the L-shaped plate 29, and the lower end of the casing of the motor three 34 is in contact with the top of the L-shaped plate 29.

[0045] The clamping assembly further includes two arcuate grooves 39 , which are respectively formed on corresponding wall surfaces of the two clamping plates 33 , and both arcuate grooves 39 correspond to the pillars 36 .

[0046] In this embodiment, whenever the pillar 36 moves or the pillar 36 does not need to move, starting the motor three 34 can drive the bidirectional screw 40 to rotate, and the bidirectional screw 40 can drive the two clamps 33 to move closer to each other until the arc grooves 39 on the two clamps 33 are in contact with the outer wall of the pillar 36 and clamp the pillar 36, so that the L-shaped plate 29 rotatably connected to the connecting rod 16 can maintain a stable connection with the slider 28, avoiding the L-shaped plate 29 being elastically and unstablely connected to the slider 28 only through the support block 35, the pillar 36, the connecting plate 37, and the spring 38, thereby avoiding the instability caused by the vibration generated by the four drill bits 14 during the drilling operation.
