Description

Technical Field

[0001] The invention relates to the technical field of brake disc production, in particular to a positioning drilling device for a brake disc. Background Art

[0002] The brake disc positioning drilling device is a special equipment used to accurately process holes on brake discs. It is mainly used in the production or maintenance of brake systems such as automobiles and motorcycles. Its core function is to ensure high precision, high efficiency and consistency of the drilling position to meet the brake disc heat dissipation, weight reduction, drainage or specific performance requirements.

[0003] During the drilling process of the brake disc, due to the large number of holes and the fact that some of the holes are located at the edge of the brake disc, it is necessary to select a support structure of specific specifications for different brake discs when drilling to ensure that the drill bit does not touch the support of the brake disc when drilling the brake disc. However, there are many specifications of brake discs on the market. Depending on the type of vehicle, the diameter of the brake disc of a passenger car is 240-400mm, the diameter of the brake disc of a motorcycle is 80-200mm, and the diameter of the brake disc of a commercial vehicle is 400-600mm. The prior art usually chooses to replace the support structure of the brake disc to ensure that the brake disc can be positioned and drilled. However, replacing the support structure of the brake disc requires disassembly and installation using screws, which is time-consuming and labor-intensive, greatly reducing the drilling efficiency of the brake disc. In addition, the support structure may slightly offset during installation, causing the drilling of the brake disc to offset, thereby reducing the drilling quality of the brake disc.

[0004] For this purpose, a positioning drilling device for a brake disc is designed. The positioning method using a suspended support and a positioning wheel is used to position the brake disc in the center of the drilling hole, which is convenient for direct drilling of the suspended position of the positioning wheel. Then, the brake disc is driven to rotate the un-drilled position to the suspended position, which is convenient for full drilling of the brake disc without the need to support the support structure of the brake disc.

[0005] After the device driving the brake disc to rotate rotates the brake disc, it is difficult to ensure that the drilling position of the brake disc is consistent with the original hole position. Therefore, our device driving the rotation uses the original holes to drive the rotation. By using the original hole reference system, the deviation between the drilled holes and the undrilled holes is reduced. However, due to the indirect drive rotation, there is still a small deviation in the position of the brake disc. At this time, the original holes are used again and a calibration mechanism is used to achieve precise adjustment of the brake disc position. Summary of the invention

The positioning mechanism and the clamping mechanism of the positioning drilling device cooperate with the rotating mechanism, so that the positioning drilling device can directly drill holes on brake disc bodies 38 of different sizes, without the need to replace different brake disc support structures and then perform the drilling task, thereby avoiding the trouble of replacing the brake disc support and the phenomenon of the support structure being offset during the replacement process, thereby ensuring the drilling efficiency and quality of different brake discs in the positioning drilling device. At the same time, the rotating mechanism rotates using the holes of the brake disc body 38, and by using the original hole reference system, the deviation between the drilled holes and the undrilled holes is reduced, and then the calibration mechanism is used to accurately position the brake disc body 38, thereby avoiding deviations in the drilling position and achieving accurate drilling of the brake disc.

[0034] Furthermore, a cleaning mechanism is provided on the surface of the base 1, and the cleaning mechanism includes a guide rod 6, which is fixedly connected to the surface of the base 1, a cleaning plate 61 is slidably connected to the surface of the guide rod 6, a protective plate 62 is fixedly connected to the surface of the cleaning plate 61, an adjusting rod 63 is rotatably connected to the surface of the protective plate 62, and the end of the adjusting rod 63 away from the protective plate 62 is rotatably connected to the bottom of the lifting platform 22, a guide plate 64 is fixedly connected to the bottom of the support frame 3, and a collecting box 65 is contacted and connected at one end of the base 1. The cleaning mechanism can collect the debris generated by drilling holes in the brake disc body 38 into the collecting box 65, and in the whole collecting process, a driving device is not used separately, but the thrust of the cleaning plate 61 and the protective plate 62 during the descent of the lifting platform 22 is used. The cleaning mechanism avoids manual cleaning of the debris dropped from the bottom of the brake disc body 38.

[0035] Furthermore, the first motor 13 drives the first screw rod 14 to rotate through the piston rod, and the first screw rod 14 drives the first square nut 15 to slide horizontally on the surface of the top plate 12 by rotation, and the first square nut 15 drives the second motor 16 and the drill rod 17 to slide synchronously, thereby changing the horizontal drilling position of the drill rod 17, and the second motor 16 drives the drill rod 17 to rotate through the output shaft, and the drill rod 17 drills the brake disc body 38 by rotation, and the third motor 2 drives the second screw rod 21 to rotate through the output shaft, and the second screw rod 21 drives the lifting platform 22 to slide and rise and fall on the surface of the supporting side plate 11 by rotation, and the lifting platform 22 will drive the brake disc body 38 to rise and fall synchronously during the lifting process, so that the brake disc body 38 moves to the position where the drill rod 17 can drill holes, and the lifting of the drill rod 17 is changed to the lifting of the brake disc body 38, thereby saving the driving device used by the cleaning structure.

[0036] Furthermore, two groups of support rods 26 are provided. The first cylinder 23 drives the connecting plate 24 to slide through the piston rod. The connecting plate 24 drives the sliding block 25 to slide on the surface of the support rod 26. The sliding block 25 drives the support frame 3 to slide synchronously on the support rod 26. The support rod 26 can change the longitudinal position of the brake disc body 38 during the sliding process. The adjustment of the position of the drill rod 17 and the adjustment of the position of the brake disc body 38 enable the drill rod 17 to drill holes at any position of the brake disc body 38. The support frame 3 is in the shape of a "mouth" as a whole. Four groups of suspended rods 31 are provided on the support frame 3. The four groups of suspended rods 31 support the brake disc body 38 on the surface of the support frame 3. The four groups of suspended rods 31 can only support the brake disc body 38 at part of the position, thereby realizing the suspended support of the brake disc body 38 by the suspended rods 31. Moreover, since the four groups of suspended rods 31 are provided, the stable support of the brake disc body 38 can be guaranteed.

[0037] Furthermore, a rectangular hole is provided on the surface of the support frame 3, and the suspended rod 31 drives the bidirectional worm 33 to rotate on the rectangular hole of the support frame 3 through the output shaft. Two groups of movable rods 36 are provided, and the bidirectional worm 33 is meshed with the two groups of movable rods 36 at the same time. The bidirectional worm 33 drives the two groups of movable rods 36 to rotate at the same time, and the rotation directions of the two groups of movable rods 36 are opposite. The movable rod 36 drives the worm wheel 35 and the positioning roller 37 to rotate synchronously through the first rotating rod 34. There are four groups of positioning rollers 37 in total. The four groups of positioning rollers 37 limit the brake disc body 38 in the suspended state by rotating. The four groups of positioning rollers 37 will continuously push the brake disc body 38 to slide on the surface of the suspended rod 31 during the rotation process until the brake disc body 38 is in the center of the four groups of suspended rods 31. At this time, the positioning rollers 37 realize the rapid positioning of the brake disc body 38 on the suspended rod 31. The positioned brake disc body 38 is limited by the clamping mechanism and then drilled directly by the drill rod 17. At this time, the drill rod 17 only drills the position of the brake disc body 38 in the air, directly avoiding the position of the suspended rod 31 and the clamping plate 51.

[0038] Furthermore, the fifth motor 4 drives the first gear 41 to rotate through the output shaft, the first gear 41 and the second gear 43 are meshed with each other, the second gear 43 and the second cylinder 44 rotate on the surface of the support frame 3 through the second rotating rod 42, the first gear 41 drives the second cylinder 44 to rotate on the surface of the support frame 3 through the second gear 43, the second cylinder 44 drives the connecting block 45 to rotate synchronously, and the third cylinder 46 drives the driving rod 47 to rise and fall through the piston rod. The diameter of the driving rod 47 is smaller than the diameter of the drill rod 17, so that the driving rod 47 can be quickly plugged into the hole drilled by the brake disc body 38. During the rotation of the second cylinder 44, the extension and contraction of the connecting block 45 are coordinated, so that the driving rod 47 can drive the brake disc body 38 to rotate on the surface of the suspended rod 31 through the hole of the brake disc body 38, and the brake disc body 38 reduces the friction through rotation, and the brake disc body 38 rotates the undrilled area to the suspended area through rotation, and the rotation angle should be appropriately adjusted according to the spacing between the holes.

[0039] Furthermore, the fourth cylinder 5 drives the clamping plate 51 to rise and fall on the surface of the suspended rod 31 through the piston rod. There are two groups of clamping plates 51, which are respectively arranged on both sides of the brake disc body 38. The clamping plate 51 clamps the brake disc body 38 on the surface of the suspended rod 31 by descending, thereby fixing the brake disc body 38, avoiding the position movement of the brake disc body 38 during the drilling process, and ensuring the stability of the drilling.

[0040] Furthermore, a guide hole is opened on the surface of the clamping plate 51, and the sixth motor 53 drives the third screw rod 54 to rotate through the output shaft. The third screw rod 54 drives the second square nut 55 to slide and rise and fall on the guide hole of the vertical plate 52 through rotation. The second square nut 55 drives the lifting plate 56 to slide and rise and fall synchronously on the vertical plate 52. The lifting plate 56 drives the fifth cylinder 57 to rise and fall synchronously. The fifth cylinder 57 drives the turntable 58 and the calibration rod 59 to rise and fall. The calibration rod 59 can pass through the positioning hole 510 during the descent process, and the calibration rod 59 falls on the hole of the brake disc body 38.

[0041] Furthermore, the lifting plate 56 drives the fifth cylinder 57, the turntable 58 and the calibration rod 59 to rise and fall synchronously. The fifth cylinder 57 drives the turntable 58 to rotate through the output shaft. The calibration rod 59 is in an eccentric position of the turntable 58. The calibration rod 59 is on the side directly above the positioning hole 510. The calibration rod 59 passes through the positioning hole 510 during the descent process, and the calibration rod 59 is always in contact with and connected to one side of the positioning hole 510. The diameter of the positioning hole 510 is the same as the diameter of the drill rod 17. At this time, the calibration rod 59 will move the hole of the brake disc body 38 to align with the positioning hole 510 during the rotation process. At this time, the position of the brake disc body 38 is calibrated, and the brake disc body 38 is locked again using the clamping mechanism to facilitate precise drilling of undrilled areas of the brake disc body 38.

[0042] Furthermore, a guide groove is opened on the surface of the base 1, and the guide rod 6 is fixedly connected to the guide groove of the base 1. The cleaning plate 61 slides on the guide groove of the base 1 through the guide rod 6. A guide hole is opened on the surface of the supporting side plate 11. The cleaning plate 61 drives the protective plate 62 to slide on the guide hole of the supporting side plate 11. The protective plate 62 is on one side of the cleaning plate 61 to prevent debris from falling on the side of the guide groove of the base 1 close to the supporting side plate 11. The guide plate 64 is horn-shaped as a whole, and can guide the debris of the brake disc body 38 to the guide groove on the surface of the base 1. During the lifting process of the lifting platform 22, the protective plate 62 and the cleaning plate 61 are driven to slide synchronously through the adjusting rod 63. The interface of the collecting box 65 is located on one side of the guide groove of the base 1. The cleaning plate 61 can push all the debris on the guide groove of the base 1 to the interface of the collecting box 65, thereby realizing automatic processing of the debris.

[0043] Working principle: The brake disc body 38 is placed on the surface of the four groups of bases 1 to realize the suspended support of the brake disc body 38, and the output shaft of the fourth motor 32 drives the two-way worm 33 to rotate, and the two-way worm 33 drives the movable rod 36 to rotate by rotating, and the movable rod 36 drives the worm wheel 35 to rotate through the first rotating rod 34, and the worm wheel 35 drives the positioning roller 37 to rotate during the rotation process, and the four groups of positioning rollers 37 rotate at the same time to push the brake disc body 38 to slide on the surface of the suspended rod 31, and the four groups of positioning rollers 37 will push the positioning roller 37 to The center position of the four groups of suspended rods 31 is used to realize the rapid positioning of the brake disc body 38. At this time, the fourth cylinder 5 drives the clamping plate 51 to descend through the piston rod, and the clamping plate 51 clamps and fixes the brake disc body 38 on the surface of the suspended rod 31. The drill rod 17 is used to drill the suspended area of ​​the brake disc body 38. After the drilling is completed, the fifth motor 4 drives the first gear 41 to rotate through the output shaft, and the first gear 41 drives the second cylinder 44 to rotate through the second gear 43. The second cylinder 44 drives the driving rod 47 to rotate synchronously, and the bidirectional worm 33 drives the second gear 41 to rotate through the second gear 43. The third cylinder 46 and the driving rod 47 are driven to telescopically move, so that the driving rod 47 can move to the top of the hole of the brake disc body 38. The third cylinder 46 inserts the driving rod 47 into the hole of the brake disc body 38 through the piston rod. The movement of the positioning roller 37 is then used to drive the brake disc body 38 to rotate on the surface of the suspended rod 31. The positioning roller 37 can reduce the friction. At this time, the hole on the brake disc body 38 will move to the bottom of the positioning hole 510. The sixth motor 53 drives the third screw rod 54 to rotate through the output shaft. The third screw rod 54 rotates The second square nut 55 is driven to slide down, and the second square nut 55 drives the calibration rod 59 to descend to the positioning hole 510, and makes the calibration rod 59 enter the hole of the brake disc body 38. At this time, the fifth cylinder 57 drives the turntable 58 to rotate through the output shaft, and the turntable 58 drives the calibration rod 59 to rotate in the hole of the brake disc body 38, so that the hole of the brake disc body 38 can be aligned with the positioning hole 510, thereby realizing the calibration of the position of the brake disc body 38. At this time, the area of ​​the brake disc body 38 to be drilled is drilled, thereby realizing the precise drilling of the brake disc.

[0044] When drilling a hole in the brake disc body 38, the guide plate 64 will guide the debris dropped from the brake disc body 38 to the guide groove of the base 1. When the drilling of the brake disc body 38 is completed, the lifting platform 22 will drive the brake disc body 38 to descend. During the descent of the lifting platform 22, the guide plate 64 drives the protective plate 62 and the cleaning plate 61 to slide on the surface of the base 1. The cleaning plate 61 will push the debris on the guide groove to the interface of the collection box 65 on the guide groove of the base 1, thereby realizing automatic cleaning of the debris of the brake disc body 38 and reducing the labor of the operating workers.
