Description

Technical Field

[0001] The invention belongs to the technical field of brake disc processing, in particular to an automatic punching device for brake disc processing. Background Art

[0002] The brake disc is a core component of a vehicle's braking system. Essentially, it's a metal disc that rotates synchronously with the wheel. The brake caliper grips the brake pad, creating friction with it and converting the vehicle's kinetic energy into heat, slowing or stopping the vehicle. During the manufacturing process, the brake disc is perforated. The resulting ventilation holes accelerate air convection, allowing heat to diffuse rapidly through the holes, thereby reducing heat accumulation and maintaining the disc's braking performance.

[0024] A turntable 48 is rotatably provided in the middle of one side of the inner cavity of the shell 18, and a connecting rod 3 49 is rotatably provided at the lower end of the positioning block 27. One end of the connecting rod 3 49 is rotatably provided on the turntable 48. A motor 11 47 is fixedly connected to the middle of the lower end surface of the shell 18, and the output end of the motor 11 47 is fixedly connected to the turntable 48.

[0025] One end of the fixing ring 8 is threadedly connected to the threaded rod 2 7, both ends of the threaded rod 2 7 are rotatably set on the slot plate 1 5, the upper end of the slot plate 1 5 is fixedly connected to the motor 2 6, and the output end of the motor 26 is fixedly connected to one end of the threaded rod 2 7.

[0026] A plurality of stretching rods 37 are radially distributed and slidably connected to the upper end surface of the mounting ring 31 , and one end of the stretching rod 37 is fixedly connected to one side of the elastic fabric 2 32 .

[0027] One end of the stretching rod 37 is rotatably provided with a connecting rod 2 36, and one end of the connecting rod 2 36 is rotatably provided with an adjusting ring 33. One side of the adjusting ring 33 is slidably connected to the mounting ring 31. One side of the upper end of the mounting ring 31 is fixedly connected to a motor 8 34. The output end of the motor 8 34 is fixedly connected to a threaded rod 5 35. The threaded rod 5 35 is threadedly connected to one side of the adjusting ring 33, and the adjusting ring 33 is slidably connected to the mounting ring 31.

[0028] Specifically, in the prior art, when drilling a brake disc, debris is thrown out by the cutting force and splashes around, clinging to the disc surface and affecting the disc's appearance. After drilling, even if the remaining debris is cleaned, it is difficult to completely clean it due to its strong adhesion and dispersion, which still affects the disc's appearance.

[0029] Therefore, in order to solve the above problems, when using this embodiment, the inner hole of the brake disc to be punched is set on multiple positioning blocks 27, and the motor 11 47 drives the turntable 48 to rotate so that the multiple connecting rods 3 49 rotate at the same time, so that the multiple positioning blocks 27 move radially at the same time and contact with the inner hole wall of the brake disc, thereby fixing the brake disc.

[0030] The specifications of the drill rod 30 can be replaced in real time through the external structure to adapt to different drilling requirements. This replacement method is a prior art and will not be described in detail here. When a drill rod 30 of appropriate specifications is installed at the output end of motor 7 29, since the axis of the output end of motor 7 29 coincides with the axis of the mounting ring 31, the motor 8 34 can be used to drive the threaded rod 5 35 to rotate according to the diameter of the drill rod 30, so that the adjustment ring 33 moves upward. Then, under the action of connecting rod 2 36, the stretching rod 37 can be driven to slide on the mounting ring 31, and the elastic cloth 2 32 can be pulled by the end of the stretching rod 37 to adjust the size of the through hole in the middle of the elastic cloth 2 32. Under the premise of not contacting the drill rod 30, the size of the through hole is reduced to the greatest extent. Then, the threaded rod 3 13 is driven to rotate by motor 3 14, and the threaded rod 4 15 is driven by motor 4 16. The position of the brake disc is adjusted by rotation, so that the area to be drilled is aligned with the through-hole in the middle of the second elastic cloth 32. Then, the second motor 6 drives the second threaded rod 7 to rotate, driving the fixing ring 8 downward until the second elastic cloth 32 and the first elastic cloth 9 are in contact with the surface of the brake disc. At this point, the drill rod 30 is driven downward by the cylinder 11 and passed through the through-hole in the middle of the second elastic cloth 32. Simultaneously, the seventh motor 29 drives the drill rod 30 to rotate, drilling the brake disc. Since the surface of the brake disc, except for the drilling area, is covered by the second elastic cloth 32 and the first elastic cloth 9, flying debris is intercepted by the second elastic cloth 32 and the first elastic cloth 9 and does not adhere to the brake disc surface. The above operation is then repeated. Each time the drill rod 30 is replaced, the second elastic cloth 32 will adapt to its size, significantly reducing the amount of debris adhering to the brake disc surface, thereby ensuring the appearance quality of the brake disc. When the remaining debris on the brake disc surface is subsequently cleaned, only a small amount of debris remains at the edge of the drill hole, making it easier to clean.

[0031] In this embodiment, Figure 1 、 Figure 3 、 Figure 5-Figure 8 As shown, the workbench 1 is also provided with a downward pressing and tightening assembly; The downward pressure and tightening assembly includes a transverse plate 2 that is slidably connected to one side of the upper end surface of the workbench 1, and a groove plate 2 slidably connected to one side of the transverse plate 2, and a telescopic rod 21 is inserted and slidably connected to the inner side of the groove plate 21, and a mounting plate 22 is rotatably provided at the end of the telescopic rod 21, and one end of the mounting plate 22 is fixedly connected to a plurality of support columns 23, and the lower end of the support column 23 is fixedly connected to a fixed disk 24, and the upper end surface of the fixed disk 24 is radially distributed and slidably connected to a plurality of adjusting rods 26, and the lower end of the adjusting rod 26 is fixedly connected to a pressure block 28, and a reel 46 is rotatably provided on one side of the pressure block 28, and a steel wire rope 44 is wound around the reel 46, and one end of the steel wire rope 44 is fixedly connected to one end of the pressure block 28 on the other side.

[0032] One side of the lower end of the transverse plate 2 is threadedly connected to a threaded rod 4, and both ends of the threaded rod 4 are rotatably set on the workbench 1. One side of the upper end surface of the workbench 1 is fixedly connected to a motor 3, and the output end of the motor 3 is fixedly connected to one end of the threaded rod 4. One end of the slot plate 2 41 is threadedly connected to a threaded rod 7 43, and both ends of the threaded rod 7 43 are rotatably set on the transverse plate 2. One side of the transverse plate 2 is fixedly connected to a motor 9 42, and the output end of the motor 9 42 is fixedly connected to one end of the threaded rod 7 43. One end of the inner cavity of the slot plate 2 41 is fixedly connected to an electric push rod 40, and the piston end of the electric push rod 40 is fixedly connected to one end of the telescopic rod 21.

[0033] One end of the telescopic rod 21 is fixedly connected to the motor 5 20 , and the output end of the motor 5 20 is fixedly connected to one end of the mounting plate 22 .

[0034] One end of the upper side of the adjusting rod 26 is rotatably provided with a connecting rod 2 36, and one end of the connecting rod 2 36 is rotatably provided with a threaded block 39, and the threaded block 39 is threadedly connected to a threaded rod 6 38. The upper end of the threaded rod 6 38 is rotatably provided on the mounting plate 22, and the lower end is rotatably provided on the fixed disk 24. The middle part of the lower end surface of the fixed disk 24 is fixedly connected to a motor 6 25, and the output end of the motor 6 25 is fixedly connected to one end of the threaded rod 6 38. One side of the upper end of the pressure block 28 is fixedly connected to a motor 10 45, and the output end of the motor 10 45 is fixedly connected to one end of the reel 46.

[0035] Specifically, in the above embodiment, although elastic cloth 2 32 and elastic cloth 1 9 can be used to cover the brake disc surface to prevent debris from splashing onto the disc surface, many brake discs typically have a hollow structure with a small central disc that is raised, dividing the disc into two parts, creating a ventilation channel and improving heat dissipation. However, when drilling holes in such brake discs, due to the uneven heights of the inner and outer parts, when drilling holes in the outer ring, the mounting ring 31 is aligned with the outer ring area of ​​the disc. Therefore, when elastic cloth 2 32 is flush with the disc surface, elastic cloth 1 9 is squeezed by the central disc, forming a bulge. Furthermore, the side of the central disc is not tightly attached to elastic cloth 1 9, resulting in some redundant space. During the drilling process, debris can easily enter through the gap between elastic cloth 1 9 and the disc and adhere to the disc surface, thus affecting the debris interception effect.

[0036] Therefore, in order to solve the above problem, when it is necessary to punch a hole in the outer ring of the brake disc, the motor 13 drives the threaded rod 14 to rotate, the motor 9 42 drives the threaded rod 7 43 to rotate, and the electric push rod 40 drives the telescopic rod 21 to slide in the inner cavity of the slot plate 2 41 to adjust the position of the fixed disk 24 in the x, y, and z axis directions. At the same time, the motor 5 20 drives the mounting plate 22 to rotate, so that the fixed disk 24 can be placed at any position above the elastic cloth 19 without interfering with the motor 7 29 and other structures. The motor 6 25 drives the threaded rod 6 38 to rotate, driving the threaded block 39 to move up and down, and under the transmission of the connecting rod 1 27, the multiple adjusting rods 26 slide radially at the same time, adjusting the distance between the pressure block 28 and the axis of the fixed plate 24, so that the inner surface of the pressure block 28 is flush with the outer edge of the small disc, and then driving the pressure block 28 to fall until the bottom of the pressure block 28 is in contact with the surface of the brake disc, and the elastic cloth 19 can be squeezed by the pressure block 28 to make the elastic cloth 19 and the outer edge of the small disc fit. Then the motor 10 45 drives the reel 46 to rotate and reel in the wire rope 44, so that the elastic cloth 19 can be partially tightened to the edge of the small disc through the wire rope 44. At this time, the small disc is tightly wrapped by the elastic cloth 19, so that during the punching process, debris is not easy to enter through the gap between the elastic cloth 19 and the brake disc, further improving the interception effect of debris.

[0037] Working Principle: The inner hole of the brake disc to be drilled is placed over multiple positioning blocks 27. A motor 11 drives a turntable 48, which simultaneously rotates multiple connecting rods 3 49. This causes the positioning blocks 27 to move radially and contact the inner wall of the brake disc, securing the disc. The specifications of the drill rod 30 can be changed in real time through an external structure to accommodate different drilling requirements. This replacement method is conventional and will not be elaborated on here. When a drill rod 30 of suitable specifications is installed at the output end of motor seven 29, since the axis of the output end of motor seven 29 coincides with the axis of the mounting ring 31, the motor eight 34 can be used to drive the threaded rod five 35 to rotate according to the diameter of the drill rod 30, so that the adjustment ring 33 moves upward. Then, under the action of the connecting rod two 36, the stretching rod 37 can be driven to slide on the mounting ring 31, and the elastic cloth two 32 can be pulled by the end of the stretching rod 37 to adjust the size of the through hole in the middle of the elastic cloth two 32. Under the premise of not contacting the drill rod 30, the size of the through hole is reduced to the greatest extent. Then, the threaded rod three 13 is driven to rotate by motor three 14, and the threaded rod four 15 is driven by motor four 16. The position of the brake disc is adjusted by rotation, so that the area to be drilled is aligned with the through-hole in the middle of the second elastic cloth 32. Then, the second motor 6 drives the second threaded rod 7 to rotate, driving the fixing ring 8 downward until the second elastic cloth 32 and the first elastic cloth 9 are in contact with the surface of the brake disc. At this point, the drill rod 30 is driven downward by the cylinder 11 and passed through the through-hole in the middle of the second elastic cloth 32. Simultaneously, the seventh motor 29 drives the drill rod 30 to rotate, drilling the brake disc. Since the surface of the brake disc, except for the drilling area, is covered by the second elastic cloth 32 and the first elastic cloth 9, flying debris is intercepted by the second elastic cloth 32 and the first elastic cloth 9 and does not adhere to the brake disc surface. The above operation is then repeated. Each time the drill rod 30 is replaced, the second elastic cloth 32 will adapt to its size, significantly reducing the amount of debris adhering to the brake disc surface, thereby ensuring the appearance quality of the brake disc. When the remaining debris on the brake disc surface is subsequently cleaned, only a small amount of debris remains at the edge of the drill hole, making it easier to clean. When it is necessary to punch a hole in the outer ring of the brake disc, the motor 13 drives the threaded rod 14 to rotate, the motor 9 42 drives the threaded rod 7 43 to rotate, and the electric push rod 40 drives the telescopic rod 21 to slide in the inner cavity of the slot plate 2 41 to adjust the position of the fixed plate 24 in the x, y, and z axis directions. At the same time, the motor 5 20 drives the mounting plate 22 to rotate, so that the fixed plate 24 can be placed at any position above the elastic cloth 19 without interfering with the motor 7 29 and other structures.The motor 6 25 drives the threaded rod 6 38 to rotate, driving the threaded block 39 to move up and down, and under the transmission of the connecting rod 1 27, the multiple adjusting rods 26 slide radially at the same time, adjusting the distance between the pressure block 28 and the axis of the fixed plate 24, so that the inner surface of the pressure block 28 is flush with the outer edge of the small disc, and then driving the pressure block 28 to fall until the bottom of the pressure block 28 is in contact with the surface of the brake disc, and the elastic cloth 19 can be squeezed by the pressure block 28 to make the elastic cloth 19 and the outer edge of the small disc fit. Then the motor 10 45 drives the reel 46 to rotate and reel in the wire rope 44, so that the elastic cloth 19 can be partially tightened to the edge of the small disc through the wire rope 44. At this time, the small disc is tightly wrapped by the elastic cloth 19, so that during the punching process, debris is not easy to enter through the gap between the elastic cloth 19 and the brake disc, further improving the interception effect of debris.
