[0023] like Figures 1 to 12 As shown, the present invention provides a drilling device for processing automotive brake pads, comprising: a machine base 1; a fixed frame 2 fixedly mounted on the machine base 1; and a drilling mechanism for drilling holes in automotive brake pads.

[0024] The drilling mechanism includes: a mounting frame 7; a rotating rod 9 rotatably mounted on the mounting frame 7; a drill bit 10 fixedly mounted on the end of the rotating rod 9; a motor 8 that drives the rotating rod 9 to rotate, and the motor 8 is fixedly mounted on the mounting frame 7; a moving component that drives the mounting frame 7 to move; a collecting component that collects the debris generated during the drilling process; and a fixing component that fixes the car brake pads.

[0025] The moving component includes: a cylinder 3 fixedly mounted on a fixed frame 2; a mounting plate 5 fixedly mounted on the movable end of the cylinder 3; a limiting rod 4 for limiting the mounting plate 5, the limiting rod 4 being installed through the fixed frame 2 and fixedly connected to the mounting plate 5; a three-axis moving module 6 fixedly mounted on the mounting plate 5, and a mounting frame 7 fixedly mounted on the three-axis moving module 6.

[0026] When drilling holes in the car brake pads, the starter motor 8 drives the rotating rod 9 to rotate, and the rotating rod 9 drives the drill bit 10 to rotate. At this time, the starter cylinder 3 drives the mounting plate 5 to move downward to the set position. The setting of the limit rod 4 can prevent the mounting plate 5 from shifting when it moves.

[0027] After the mounting plate 5 is moved to the set position, the three-axis moving module 6 is activated to move the mounting frame 7, which in turn moves the drill bit 10. The three-axis moving module 6 in this application is a common moving module on the market, which can move the drill bit 10 horizontally, vertically, and longitudinally, thereby drilling holes in different positions of the car brake pads and improving the applicability of the equipment.

[0028] The collection assembly includes: a connecting pipe 28 fixedly mounted on the mounting frame 7, the connecting pipe 28 being rotatably connected to the rotating rod 9; a movable pipe 29 slidably mounted inside the connecting pipe 28; a linkage spring 30 that drives the movable pipe 29 to reset, one end of the linkage spring 30 being fixedly connected to the connecting pipe 28, and the other end of the linkage spring 30 being fixedly connected to the movable pipe 29; a collection box 25 fixedly mounted inside the machine base 1; an air pump 23 fixedly mounted on the machine base 1; an air suction pipe 27 connecting the movable pipe 29 and the collection box 25; an air inlet pipe 24 connecting the collection box 25 and the air pump 23; and a filter screen 26 slidably mounted on the collection box 25.

[0029] When drilling holes in the car brake pads, the air pump 23 is started. The air pump 23 can draw out the air filtered by the filter screen 26 in the collection box 25 through the air intake pipe 24, so that the collection box 25 generates negative pressure, which in turn causes the suction pipe 27 to generate suction. The debris generated by drilling enters the collection box 25 with the airflow and is collected. After being filtered by the filter screen 26, the debris is retained in the collection box 25.

[0030] When drilling, the bottom of the movable end first abuts against the car brake pad. As the drill bit 10 continues to drill downwards, it can drive the linkage spring 30 to compress. At this time, the connecting pipe 28 and the movable pipe 29 can block the debris, prevent the debris from spilling, and facilitate the collection of the debris.

[0031] When the drill bit 10 is not in use, the linkage spring 30 drives the movable tube 29 to reset. At this time, the connecting tube 28 and the movable tube 29 cover the drill bit 10, thereby preventing accidental contact with the drill bit 10 and improving the safety of use.

[0032] The collection assembly also includes: a switching unit for switching the airflow direction; the switching unit includes: an installation pipe 32 fixedly installed on the mounting frame 2; a movable block 33 slidably installed in the installation pipe 32; an air guide cavity 36 opened on the movable block 33; an air outlet pipe 31 connecting the air guide cavity 36 and the air pump 23; a connecting rod 34 fixedly installed on the movable block 33, and the connecting rod 34 is fixedly connected to the mounting plate 5; and an air guide pipe 35 and an air guide pipe 44 connected to the installation pipe 32.

[0033] When drilling is required, the cylinder 3 is activated to move the mounting plate 5 downward to the set position. During this process, the mounting plate 5 moves the connecting rod 34 downward, and the connecting rod 34 moves the movable block 33 downward, so that the air guide chamber 36 is connected to the air inlet end of the air guide pipe 35.

[0034] After drilling is completed, the starting cylinder 3 drives the mounting plate 5 to reset upwards, thereby driving the movable block 33 to reset upwards. At this time, the air guide chamber 36 is connected to the air inlet end of the air guide pipe 44.

[0035] The fixed components include: a rotating tube 12 rotatably mounted on the collection box 25; a movable rod 11 slidably mounted inside the rotating tube 12, the movable rod 11 being fixedly connected to the mounting plate 5; a groove 14 formed on the movable rod 11; a slider 13 fixedly mounted inside the rotating tube 12; a fixed frame 22 fixedly mounted on the machine base 1; a threaded rod 17 rotatably mounted on the fixed frame 22; a threaded tube 18 threadedly connected to the threaded rod 17; a clamping plate 19 fixedly mounted at the end of the threaded tube 18; a driven bevel gear 16 fixedly mounted at the end of the threaded rod 17; a driving bevel gear 15 fixedly sleeved on the rotating tube 12, the driving bevel gear 15 and the driven bevel gear 16 meshing with each other; a limiting tube 20 fixedly mounted on the fixed frame 22, a limiting strip 21 fixedly mounted on the threaded tube 18, a limiting groove formed inside the limiting tube 20, and the limiting strip 21 slidably mounted inside the limiting groove; the groove 14 is composed of interconnected straight grooves and spiral grooves, and the slider 13 is slidably mounted inside the groove 14.

[0036] When drilling holes in car brake pads, the brake pads need to be fixed in place to prevent them from shifting during drilling and affecting the drilling results.

[0037] The fixing components also include: a gas collecting pipe 39 fixedly installed in the machine base 1; a bladder 37 fixedly installed between the movable block 33 and the mounting pipe 32; a connecting pipe 38 connecting the gas collecting pipe 39 and the bladder 37; a push rod 42 installed through the gas collecting pipe 39, and the push rod 42 is slidably installed on the machine base 1; a positioning plate 43 fixedly installed at one end of the push rod 42, the positioning plate 43 being located within the fixing frame 22; a piston 41 fixedly installed at the other end of the push rod 42; and a reset spring 40 that drives the piston 41 to reset, one end of the reset spring 40 being fixedly connected to the piston 41, and the other end of the reset spring 40 being fixedly connected to the inner wall of the gas collecting pipe 39.

[0038] The positioning plate 43 of this application is provided with a positioning strip that matches the car brake pad. When the car brake pad is placed on the top of the positioning plate 43, the positioning strip prevents the car brake pad from moving back and forth, so that the car brake pad can only move left and right (i.e., move in the direction of the clamping plate 19).

[0039] Specifically, after the car brake pads are placed on top of the positioning plate 43, the starting cylinder 3 drives the mounting plate 5 to move downwards. This drives the drill bit 10 downwards and the movable rod 11 downwards. At this time, the slider 13 moves along the path of the spiral groove, thereby driving the rotating tube 12 to rotate. The rotating tube 12 drives the driving bevel gear 15 to rotate, the driving bevel gear 15 drives the driven bevel gear 16 to rotate, and the driven bevel gear 16 drives the threaded rod 17 to rotate. Under the limiting action of the limiting tube 20 and the limiting strip 21, the threaded tube 18 moves along the axial direction of the threaded rod 17, that is, the two threaded tubes 18 drive the adjacent clamping plates 19 to move closer to each other.

[0040] When the slider 13 enters the straight groove from the threaded groove, the two clamping plates 19 complete the clamping and fixing of the car brake pads.

[0041] As the mounting plate 5 continues to move downward to the set position, the slider 13 moves along the path of the straight groove. At this time, the rotating tube 12 no longer rotates, and the two clamping plates 19 remain fixed to the car brake pads.

[0042] In addition, cylinder 3 drives mounting plate 5 to move downward to the set position. During this process, mounting plate 5 drives connecting rod 34 to move downward, connecting rod 34 drives movable block 33 to move downward, and makes air guide chamber 36 connected to air inlet end of air guide tube 35. At the same time, due to the downward movement of movable block 33, the compression state of airbag is released. During the airbag recovery process, gas in air collection tube 39 can be drawn into airbag through connecting tube 38, which reduces the air pressure in air collection tube 39. At this time, through the elastic force of return spring 40, piston 41 can be driven downward. Piston 41 drives push rod 42 to move downward, push rod 42 drives positioning plate 43 to move downward, thereby moving the car brake pad to the bottom of the inner cavity of fixed frame 22. The setting of fixed frame 22 can further prevent debris from spilling during drilling.

[0043] When the mounting plate 5 moves to the set position, the airbag is fully restored, and at this time the positioning plate 43 drives the car brake pads to the required position, while the two clamps complete the clamping and fixing of the car brake pads.

[0044] Once the car brake pads are fixed in place, the three-axis moving module 6 is activated to drive the drill bit 10 to drill holes in the car brake pads.

[0045] After drilling is completed, the mounting plate 5 resets upwards. This resets the drill bit 10 upwards and simultaneously moves the movable rod 11 and connecting rod 34 upwards, causing the two clamping plates 19 to move away from each other and release the brake pads from their fixed position. At the same time, the airbag is squeezed again by the movable block 33, causing the gas inside the airbag to enter the gas collection pipe 39 through the connecting pipe 38. The gas pressure in the gas collection pipe 39 increases, pushing the piston 41 upwards. The piston 41 moves the push rod 42 upwards, which in turn moves the positioning plate 43 upwards. The positioning plate 43 then moves the drilled brake pads upwards, making it easier for workers to remove the drilled brake pads and place the brake pads to be processed.

[0046] The collection assembly also includes: a rotating drum 50 fixedly installed at the end of the rotating tube 12; a guide groove 51 opened on the rotating drum 50; and a slide rod 52 fixedly installed on the filter screen 26. The guide groove 51 consists of two interconnected U-shaped grooves in opposite directions, and the slide rod 52 is slidably installed in the guide groove 51.

[0047] The collection assembly also includes: a movable plate 49 fixedly mounted on the clamping plate 19, the bottom of the movable plate 49 being in contact with the top of the machine base 1, and the movable plate 49 being slidably mounted on the fixed frame 22; a round hole opened on the movable plate 49; a collection pipe 48 inserted and mounted on the collection box 25, and a filter screen 26 being slidably mounted on the collection pipe 48; a connecting pipe 45 rotatably mounted on the fixed frame 22; a second motor 46 driving the connecting pipe 45 to rotate, and the second motor 46 being fixedly mounted on the fixed frame 22; a nozzle 47 inserted and mounted on the connecting pipe 45; and a second air guide pipe 44 communicating with the connecting pipe 45, and the air outlet end of the second air guide pipe 44 being rotatably connected to the connecting pipe 45.

[0048] When the rotating tube 12 rotates, it drives the rotating drum 50 to rotate, causing the slide rod 52 to move along the path of the guide groove 51. Under the action of the collecting tube 48, the slide rod 52 drives the filter screen 26 to move back and forth along the axial direction of the collecting tube 48, causing the filter screen 26 to vibrate. This vibrates the filter screen 26, which shakes the debris attached to the bottom of the filter screen 26 to the bottom of the inner cavity of the collecting box 25, thus cleaning the filter screen 26 and preventing the filter screen 26 from clogging and affecting the filtration effect.

[0049] During drilling, the air guide chamber 36 is connected to the air inlet end of the air guide pipe 35. At this time, the air pump 23 discharges the filtered gas through the air outlet pipe 31, and then passes through the air guide chamber 36 and the air guide pipe 35 in sequence into the movable pipe 29, thereby cleaning the debris on the surface of the drill bit 10. At the same time, the air outlet end of the air guide pipe 35 is aligned with the air inlet end of the suction pipe 27, so that the air guide pipe 35 blows the debris directly into the suction pipe 27, allowing the suction pipe 27 to quickly suck the debris into the collection box 25, improving the collection efficiency of the debris.

[0050] During drilling, the two clamping plates 19 move closer to each other and clamp and fix the car brake pads. As a result, the two clamping plates 19 drive the adjacent movable plates 49 to move closer to each other, so that the round holes on the two movable plates 49 are completely misaligned with the adjacent collection pipes 48, thereby achieving a seal on the top of the collection pipes 48. At this time, it is convenient for the air pump 23 to quickly extract the gas from the collection box 25.

[0051] After drilling is completed, the air guide chamber 36 is connected to the air inlet end of the second air guide pipe 44. At this time, the two clamping plates 19 are reset, thereby driving the adjacent movable plate 49 to reset. At this time, the round hole on the movable plate 49 is connected to the top of the collecting pipe 48.

[0052] At this time, the air pump 23 is started, and the filtered gas is discharged through the air outlet pipe 31 and passes through the air guide chamber 36 and the second air guide pipe 44 in sequence into the connecting pipe 45. At the same time, the second motor 46 is started to drive the connecting pipe 45 to rotate in both directions, thereby realizing the swing of the nozzle 47. The gas entering the connecting pipe 45 is sprayed out through multiple nozzles 47, thereby cleaning the debris in the fixed frame 22, as well as on the positioning plate 43 and the clamping plate 19.

[0053] Because a negative pressure is generated inside the collection box 25 at this time, the debris inside the fixed frame 22, as well as on the positioning plate 43 and the clamping plate 19, enters the collection box 25 through the collection pipe 48 with the airflow for collection. This realizes the automatic cleaning and collection of debris inside the fixed frame 22, as well as on the positioning plate 43 and the clamping plate 19, avoiding debris adhering to the top of the positioning plate 43 and the clamping side of the clamping plate 19, which would cause scratches on the surface of the car brake pads when clamping them, affecting the processing quality of the car brake pads.

[0054] It should be noted that the collection box 25 is equipped with a sealed door, which allows for the removal of debris inside the collection box 25 when the sealed door is opened.

[0055] In this invention, by setting up the collection component, on the one hand, the debris generated during drilling can be collected and cleaned in a timely manner to avoid debris spilling and polluting the working environment. On the other hand, after drilling, the debris inside the fixing frame 22, as well as on the positioning plate 43 and the clamping plate 19, can be automatically cleaned and collected, preventing debris from adhering to the top of the positioning plate 43 and the clamping side of the clamping plate 19, which would cause scratches on the surface of the car brake pads when clamping them, thus affecting the processing quality of the car brake pads.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
