Description

Technical Field

[0001] This invention relates to the field of automotive braking system component manufacturing, and more particularly to a mechanism for grinding surface defects in automotive calipers. Background Technology

[0002] Automotive calipers are components that apply force to brake discs. They are caliper-like devices that function to slow down, stop, or maintain a stopped state of the moving wheels, and are typically used in disc brake systems. They are key components in the automotive braking system, responsible for converting the force exerted by the driver's brake pedal into braking force on the tires. Automotive calipers primarily receive hydraulic pressure from the master cylinder through the brake lines, then apply this hydraulic pressure to the piston inside the caliper. The piston then pushes the brake pads, causing them to engage with the brake disc. The friction generated between the pads and discs slows the vehicle, and the vehicle's kinetic energy is converted into frictional heat energy and dissipated into the atmosphere.

[0003] As a core safety component of automobiles, the grinding quality of calipers directly affects product performance and safety reputation. Existing equipment grinding stations are mostly single-station designs with fixed grinding head spacing, making it impossible to flexibly adjust the grinding position according to the specifications and dimensions of the calipers. This results in poor processing adaptability. At the same time, the single-station operation mode leads to low grinding efficiency on the production line, making it unsuitable for mass production. Grinding head replacement is cumbersome, as it is impossible to quickly switch between grinding heads of different precision on the same grinding mechanism. For different degrees of defects on the caliper surface, it is necessary to replace multiple machines or disassemble and reassemble the grinding heads multiple times, which seriously reduces the efficiency of handling caliper surface defects.

[0075] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0076] Figures 1 to 17 The diagram shown is a structural schematic of an embodiment of the present invention for grinding surface defects in automotive calipers.

[0077] A surface defect grinding mechanism for automotive calipers includes a supporting protective frame 1, a grinding unit and a discharge unit. The grinding unit is connected to the discharge unit in a transmission manner, and the waste material ground by the grinding unit is collected and processed by the discharge unit.

[0078] Two supporting side plates 2 are respectively disposed on both sides of the grinding unit, and the two supporting side plates 2 are rotatably connected to the discharge unit;

[0079] The grinding unit includes two mounting circular plates 4, and multiple sets of adjusting components 3 arranged in a ring array are installed between the two mounting circular plates 4. Each set of adjusting components 3 is connected to two moving brackets 5 in a transmission connection. Grinding components 6 are installed at the moving brackets 5.

[0080] The discharge unit includes a collection cylinder 8, two mounting circular plates 4 are respectively connected to the surface of the collection cylinder 8, the two ends of the collection cylinder 8 are respectively connected to the switching component 7, and the collection cylinder 8 is installed at the support side plate 2.

[0081] When grinding automotive calipers, manual loading and unloading of finished products are performed on a pallet inside the grinding chamber. The pallet is then transported to the grinding chamber by a conveyor line. The vision system 26 takes a picture of the pallet and provides the robot 25 with the gripping posture of the automotive caliper.

[0082] After the robot 25 picks up the part, it places the car caliper on the transfer table 16 tooling and then grabs the car caliper to ensure accurate gripping posture and ensure the quality of subsequent grinding.

[0083] Robot 25 picks up car calipers and takes 2D photos (5 angles) to identify defects in the calipers (when an unrepairable defect is identified, the defective part is automatically returned to the tray).

[0084] Robot 25 grabs the car caliper, takes a 3D photo to extract polishing information, and selects the appropriate polishing tools (if the burrs are too large, they will be processed first with a milling cutter, and then polished with sanding belt, file and other tools).

[0085] The robot 25 holds the part and moves it to the grinding mechanism module 22 to grind the surface defects;

[0086] After the polishing is completed, robot 25 places the car caliper on the transfer table 16 and picks up the car caliper from the other side;

[0087] After the robot 25 picks up the car caliper, it takes another picture (one side of the remaining direction) to identify defects (when an unrepairable defect is identified, the problematic part is automatically put back into the tray).

[0088] Continue to grind the burrs on the other side of the automotive caliper (if there is a blanking process, it will be done after grinding).

[0089] After polishing, robot 25 picks up the car caliper and places it into the marking device for marking.

[0090] Robot 25 places the finished car caliper back onto the tray and continues processing the next product.

[0091] Both the 2D and 3D photography mentioned above are achieved through the vision system 26.

[0092] In this technical solution, the grinding unit performs grinding operations on the automotive calipers, and the discharge unit collects the grinding waste in a centralized manner to prevent the grinding waste from splashing around the workbench and polluting the surrounding environment.

[0093] Furthermore, the distance between the two grinding components 6 can be adjusted by adjusting the position component 3, thereby adjusting the grinding position. The grinding components 6 on both sides can achieve dual-station grinding operation, thereby improving the grinding efficiency of the production line.

[0094] Meanwhile, the grinding component 6 can be switched by switching component 7, and grinding components 6 with different grinding precision can be switched. Grinding of different precision can be achieved in one grinding mechanism, which improves the efficiency of surface defect treatment of automotive calipers.

[0095] The collection cylinder 8 can collect grinding waste in real time, and the collection component 10 pushes the pusher plate 9 to push the waste collected in the collection cylinder 8 to the collection frame shell 11 for centralized collection, which facilitates the centralized treatment of waste.

[0096] The adjustment assembly 3 includes a bidirectional threaded shaft 31, with its two ends rotatably connected to two mounting circular plates 4 respectively, and two movable brackets 5 threadedly connected to the surface of the bidirectional threaded shaft 31.

[0097] Furthermore, multiple limiting track posts 32 are connected between the two mounting circular plates 4, and the surfaces of the limiting track posts 32 are slidably connected to the movable bracket 5.

[0098] In this technical solution, the rotating adjustment component 3 drives the movable brackets 5 on both sides and the grinding component 6 to move synchronously, thereby adjusting the position of the grinding component 6 and thus adjusting the grinding position.

[0099] In use, the rotation of the bidirectional threaded shaft 31 drives the two corresponding movable brackets 5 to move towards or away from each other along the limiting track column 32. When the movable brackets 5 move, they drive the corresponding grinding components 6 to move synchronously. The position of the grinding components 6 can be adjusted according to the grinding position of the car caliper, making the grinding of the car caliper more flexible.

[0100] One end of each of the multiple bidirectional threaded shafts 31 is connected to the synchronous drive assembly 12. The synchronous drive assembly 12 includes a large gear ring 122. The inner side of the large gear ring 122 is meshed with multiple small gears 123 arranged in a ring array. The multiple small gears 123 are respectively connected to one end of the bidirectional threaded shafts 31.

[0101] One of the small gears 123 is connected to the output end of the synchronous power source 121.

[0102] Specifically, one end of the bidirectional threaded shaft 31 is rotatably connected to a mounting circular plate 4, and the other end of the other bidirectional threaded shaft 31 is rotatably connected through to another mounting circular plate 4.

[0103] Furthermore, the synchronous power source 121 is installed on the outside of the protective housing 125, one side of the protective housing 125 is connected to the side of the mounting circular plate 4, and the large gear ring 122 and the small gear 123 are both located on the inside of the protective housing 125.

[0104] The inner wall of the protective shell 125 is connected to an anti-deviation track ring 124, and a track groove is provided on the outer side of the large toothed ring 122. The anti-deviation track ring 124 is slidably connected to the large toothed ring 122 through the track groove.

[0105] In this technical solution, multiple position adjustment components 3 are driven synchronously by the synchronous drive component 12.

[0106] In use, the synchronous power source 121 drives the large gear ring 122 to rotate along the anti-deviation track ring 124, thereby synchronously driving multiple small gears 123 to rotate. When the small gears 123 rotate, they drive the bidirectional threaded shaft 31 to rotate, so that multiple bidirectional threaded shafts 31 can rotate synchronously, and the grinding components 6 on both sides can move synchronously.

[0107] The grinding assembly 6 includes three drive wheels 61 arranged in a triangular structure. The surfaces of the three drive wheels 61 are covered with a grinding belt 62, and the three drive wheels 61 are connected by the grinding belt 62.

[0108] Both ends of the transmission wheel 61 are connected to anti-detachment rotating shafts 63, which are rotatably connected to the movable bracket 5.

[0109] Furthermore, one end of each of the two drive wheels 61 is connected to a bevel gear 64, the side of the bevel gear 64 meshes with a bevel gear 65, the bevel gear 65 is connected to a drive shaft 66, one end of each of the two drive shafts 66 is connected to the two output ends of a grinding power source 67, and the grinding power source 67 is installed in the inner cavity of the mounting housing 68.

[0110] In this technical solution, the surface of the automotive caliper is polished using the polishing component 6.

[0111] In use, the grinding power source 67 drives the transmission shaft 66 to rotate, which in turn drives the second bevel gear 65 to rotate, which in turn drives the first bevel gear 64 to rotate. When the first bevel gear 64 rotates, it drives the anti-disengagement shaft 63 to rotate, which in turn drives the transmission wheel 61 to rotate. When the transmission wheel 61 rotates, it drives the grinding belt 62 to rotate, so that all three transmission wheels 61 can rotate. The rotating grinding belt 62 is used to grind the surface defects of the car caliper.

[0112] The upper part of the movable bracket 5 is connected to a contact component 13, which includes a mounting frame 131. The bottom of the mounting frame 131 is connected to the top of the movable bracket 5.

[0113] Multiple rolling shafts 132 are rotatably connected to the inner side of the mounting frame 131, and the surface of the rolling shafts 132 contacts one side of the grinding belt 62.

[0114] Specifically, the mounting housing 68 is connected to the movable bracket 5 and the mounting frame 131 on one side.

[0117] The switching component 7 includes a switching power source 71, which is installed on one side of the support side plate 2. The output end of the switching power source 71 is connected to a drive gear 72.

[0118] The side of the drive gear 72 meshes with the transmission gear 73, and the transmission gear 73 is connected to the surface of the collecting cylinder 8.

[0119] Furthermore, both the switching power source 71 and the drive gear 72 are provided with a switching housing 74 on their outer sides, and one side of the switching housing 74 is connected to one side of the support side plate 2.

[0120] In this technical solution, the grinding component 6 is switched by the switching component 7, thereby grinding the automotive caliper with different precision.

[0121] Furthermore, an annular rotating track 75 is connected to one side of the mounting circular plate 4. The annular rotating track 75 is slidably connected to the inner side of the annular track sleeve 76. One side of the annular track sleeve 76 is connected to one side of the support side plate 2.

[0122] In use, by switching the power source 71 to drive the drive gear 72 to rotate, which in turn drives the transmission gear 73 to rotate. When the transmission gear 73 rotates, it drives the collection cylinder 8 to rotate, which in turn drives the mounting plate 4, the movable bracket 5, and the grinding assembly 6 to rotate, thus switching the grinding assembly 6.

[0123] When the mounting plate 4 rotates, it drives the annular rotating track 75 to rotate along the annular track housing 76, thus limiting the rotation trajectory of the mounting plate 4 and other structures and increasing stability.

[0124] The discharge unit includes a pusher plate 9, which is slidably disposed inside the collection cylinder 8. Both sides of the pusher plate 9 are connected to the collection assembly 10 for transmission. The collection assembly 10 is installed on one side of the support side plate 2.

[0125] In this technical solution, the debris generated during grinding is collected and processed through a discharge unit.

[0126] Multiple partition guide plates 14 arranged in a ring array are connected between the two support side plates 2. Each partition guide plate 14 is respectively set between the two adjustment components 3, and one side of the partition guide plate 14 is connected to the surface of the collection cylinder 8.

[0127] In this technical solution, a partition guide plate 14 is used to facilitate the introduction of grinding debris into the collection cylinder 8 for collection.

[0128] The collecting component 10 includes a take-up shaft 101, with two symmetrically distributed limiting side plates 102 connected to the surface of the take-up shaft 101. A pull rope 103 is connected to the middle of the take-up shaft 101, and one end of the pull rope 103 away from the take-up shaft 101 is connected to one side of the push plate 9.

[0129] Both ends of the take-up and take-down shaft 101 are rotatably connected to reinforcing side plates 104. One side of the reinforcing side plate 104 is connected to one side of the supporting side plate 2. One end of the take-up and take-down shaft 101 is connected to the output end of the collecting power source 105. The collecting power source 105 is installed on one side of the reinforcing side plate 104.

[0130] Specifically, pull ropes 103 are connected to both sides of the push plate 9.

[0131] In this technical solution, the pusher plate 9 is moved by the collection component 10, thereby collecting the grinding debris in the collection cylinder 8 using the pusher plate 9.

[0132] A collection frame shell 11 is provided at both ends of the collection cylinder 8, and the collection frame shell 11 is placed at the bottom of the inner cavity of the supporting protective outer frame 1.

[0133] In this technical solution, the debris discharged from both ends of the collection cylinder 8 is collected by two collection frames 11.

[0134] In use, the collection power source 105 drives the take-up and release shaft 101 to rotate, thereby using the take-up and release shaft 101 to wind up or release the pull rope 103. When the pull rope 103 moves, it drives the pusher plate 9 to move, and the pusher plate 9 pushes the grinding debris in the collection cylinder 8, so that the grinding debris is discharged from both ends of the collection cylinder 8 and falls into the collection frame shell 11 for collection.

[0135] The collecting cylinder 8 includes an outer sleeve 81 and an inner concentrating cylinder 82. The outer sleeve 81 is rotatably fitted onto the surface of the inner concentrating cylinder 82. Both ends of the inner concentrating cylinder 82 extend from both ends of the outer sleeve 81. Both ends of the inner concentrating cylinder 82 are connected to a plurality of fixed support columns 83 arranged in a ring array. The end of the fixed support column 83 away from the inner concentrating cylinder 82 is connected to one side of the switching housing 74.

[0136] The outer sleeve 81 has multiple external collection ports arranged in a ring array on its surface, and each external collection port is located between two partition guide plates 14;

[0137] The inner collection cylinder 82 has an inner collection port on its top side, and the pusher plate 9 is slidably disposed inside the inner collection cylinder 82.

[0138] During debris collection, the outer collection port located at the top coincides with the inner collection port. At this time, the debris enters the inner cavity of the inner concentrator 82 from the outer and inner collection ports. Then, the debris is pushed to the outside of the inner concentrator 82 by the movement of the pusher plate 9 and falls into the collection frame shell 11.

[0139] When the grinding component 6 is switched, the outer sleeve 81 rotates accordingly. At this time, the outer collection port rotates while the inner collection port remains stationary, so that different outer collection ports can be adjusted to be directly above the inner collection port according to the use of the corresponding grinding component 6. That is, when the outer collection port and the inner collection port coincide, the grinding debris enters the inner cavity of the inner collection cylinder 82 through the outer collection port and the inner collection port in sequence for collection.

[0140] It is worth noting that the surface of the outer sleeve 81 is connected to the mounting circular plate 4, the transmission gear 73, and the partition guide plate 14, respectively.

[0141] Both the mounting housing 68 and the protective housing 125 have ventilation holes.

[0142] The power source 67 is used for grinding, the power source 71 is switched, the power source 105 is collected, and the power source 121 is synchronized to a motor or other equipment that can output rotational kinetic energy.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
