Description

Technical Field

[0001] This invention relates to the field of brake pad processing equipment technology, specifically to a double-sided chamfering machine for automotive brake pads. Background Technology

[0002] Brake pads are the most critical safety component in a car's braking system. They are mainly composed of a friction material layer, a heat insulation layer, an adhesive layer, and a backing plate.

[0003] After brake pads are manufactured, considering that they will be subjected to high-frequency vibration and thermal stress during braking, the right-angled edges are prone to cracking or chipping due to stress concentration. At the same time, the right-angled edges may generate high-frequency vibration when in contact with the brake disc, causing sharp noise. Therefore, it is necessary to cut or grind both sides of the friction material layer at a certain angle. Traditional chamfering methods use grinding equipment to grind both sides of the friction material layer. During the grinding process, the grinding material will wear down the outer particle layer due to friction, so the grinding material needs to be replaced frequently, which reduces the efficiency of chamfering and grinding the brake pads. Summary of the Invention

[0004] The purpose of this invention is to provide a double-sided chamfering machine for automotive brake pads, so as to solve the problem mentioned in the background art that when grinding brake pads, it is necessary to change the grinding material, which leads to long grinding time and low efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a double-sided chamfering machine for automotive brake pads, comprising a movable base and a moving mechanism for moving the movable base, and a mounting bracket mounted on the movable base. The mounting bracket is equipped with a locking component for brake pad docking, and brackets are provided on both sides of the movable base. An adjusting ring is fixed on the bracket, and a contact recess is provided near the bracket on the adjusting ring. A support plate is fixed on the bracket, and a rotating frame is rotatably mounted on the support plate. A grinding part that fits against the adjusting ring is mounted on the rotating frame, and a driving component for driving the grinding part is mounted on the adjusting ring. A linkage part is provided at the bottom of the movable base, and the linkage part docks with the two rotating frames and drives the rotating frames to rotate through the linkage part.

[0006] Preferably, there are three grinding sections, which are evenly distributed on the outside of the rotating frame. Each grinding section includes a mounting plate fixed to the rotating frame. The mounting plate has sliding openings at both ends, and mounting blocks are fixed on the mounting plate. Two connecting posts are slidably inserted into both ends of the mounting blocks. End plates are fixed to the outer ends of the two connecting posts. A mating part that rotatably connects with the driving component is inserted into the end plate. A grinding belt is sleeved on the outside of the two mating parts. A compression spring for squeezing the end plate outward is sleeved on the outside of the connecting posts.

[0007] Preferably, the docking component includes a drive rod that is rotatably docked with the end plate via a bearing. A drive wheel is fixed to the outside of the drive rod, and a grinding belt is sleeved on the outside of the drive wheel. An I-shaped ring that fits against the inner wall of the sliding groove is fixed to the outside of the drive rod. The drive rod fits against the adjusting ring and the inner wall of the contact recess. A docking gear that is adapted to the drive component is fixed to the outside of one of the drive rods.

[0008] Preferably, the outer end of the drive rod is fixed with a roller that fits against the outer side of the adjusting ring.

[0009] Preferably, the driving component includes a drive motor fixed to the outside of the adjusting ring via a motor frame, and a drive gear adapted to the mating gear is fixed to the output end of the drive motor.

[0010] Preferably, the linkage part includes a toothed plate fixed to the bottom of the movable seat and a linkage gear disposed at the bottom of the movable seat. A docking shaft is fixed inside the linkage gear, and both ends of the docking shaft are fixed to the rotating shafts of the two rotating frames through universal joints. The number of teeth on the toothed plate is one-third of the number of teeth on the linkage gear, and an angle positioning component is disposed on the outside of the linkage gear.

[0011] Preferably, the angle positioning component includes an electric push rod, the top of which is fixed with a U-shaped frame, and three conical openings are equally spaced on both sides of the linkage gear, with both ends of the U-shaped frame inserted into the conical openings and fitting against the inner wall.

[0012] Preferably, a support tube is fixed on the support plate, and the support tube is rotatably sleeved on the outside of the rotating shaft of the rotating frame and abuts against the inner wall of the rotating frame.

[0013] Preferably, the locking component includes a connecting rod fixed to the mounting bracket, a pressure plate slidably sleeved on the outer side of the connecting rod, and a limit block fixed on the top of the connecting rod. The brake pad is placed between the mounting bracket and the pressure plate, and an inclined block is fixed on the outer end of the pressure plate.

[0016] This invention improves upon the traditional brake pad grinding method. Personnel only need to place multiple brake pads sequentially into the locking mechanism. The moving seat moves, causing the brake pads to contact and grind with the grinding head in turn. After grinding a certain number of brake pads, the moving seat, in conjunction with the linkage, rotates different grinding heads to their designated grinding positions to grind the brake pads. This reduces the time spent changing grinding materials and improves the efficiency of chamfering brake pads. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1: Please refer to Figure 1 - Figure 4 and Figure 9 The illustrated automotive brake pad double-sided chamfering machine includes a movable base 1 and a moving mechanism that drives the movable base 1 to move. It also includes a mounting bracket 2 installed on the movable base 1, a locking member 3 for brake pad docking installed on the mounting bracket 2, and brackets 4 arranged on both sides of the movable base 1. An adjusting ring 5 is fixed on the bracket 4, and a contact notch 6 is opened near the bracket 4 on the adjusting ring 5. A support plate 7 is fixed on the bracket 4, and a rotating frame 8 is rotatably mounted on the support plate 7. A grinding part 9 that fits against the adjusting ring 5 is installed on the rotating frame 8. A driving member 10 for driving the grinding part 9 is installed on the adjusting ring 5, and a linkage part 11 is arranged at the bottom of the movable base 1. The linkage part 11 docks with the two rotating frames 8 and drives the rotating frames 8 to rotate through the linkage part 11.

[0030] In this solution, the moving mechanism can be, but is not limited to, the existing screw drive mechanism, which drives the moving seat 1 to move back and forth horizontally, so that several brake pads positioned by the locking part 3 on the moving seat 1 contact the grinding part 9 in sequence, and the two sides of the brake pads are chamfered.

[0031] During the movement of the movable seat 1, the drive component 10 is triggered to drive the two rotating frames 8 to rotate at the same angle, which in turn causes the grinding part 9 to rotate and replace the worn grinding part 9. Thus, when changing the grinding material, there is no need to stop the machine, which improves the efficiency of chamfering grinding of the brake pads.

[0032] For further details, please refer to [link / reference]. Figure 4 - Figure 9 The grinding section 9 is provided in three parts and is distributed at equal angles on the outside of the rotating frame 8. The grinding section 9 includes a mounting plate 12 fixed to the rotating frame 8. The mounting plate 12 has sliding openings 13 at both ends. The mounting plate 12 is fixed with mounting blocks 14. The mounting blocks 14 are slidably inserted with two connecting posts 15 at both ends. The outer ends of the two connecting posts 15 are fixed with end plates 16. The end plates 16 are rotatably inserted with docking parts 17 that are opposite to the driving part 10. The two docking parts 17 are covered with grinding belts 18. The connecting posts 15 are covered with compression springs 19 for pressing the end plates 16 to move outward.

[0033] The docking component 17 includes a drive rod 20 that is rotatably docked with the end plate 16 via a bearing. A drive wheel 21 is fixed to the outside of the drive rod 20, and a retaining ring is fixed to the outside of the drive wheel 21 to prevent the grinding belt 18 from shifting during rotation. The grinding belt 18 is sleeved on the outside of the drive wheel 21. An I-shaped ring 22 that fits against the inner wall of the sliding groove 13 is fixed to the outside of the drive rod 20. The drive rod 20 fits against the adjusting ring 5 and the inner wall of the contact recess 6. A docking gear 23 that is adapted to the drive component 10 is fixed to the outside of one of the drive rods 20.

[0034] Also see Figure 4 , Figure 7 and Figure 8 The drive unit 10 includes a drive motor 25 fixed to the outside of the adjustment ring 5 by a motor frame, and a drive gear 26 adapted to the mating gear 23 is fixed at the output end of the drive motor 25.

[0035] In this design, the principle of the grinding section 9 for chamfering both sides of the brake pads is as follows: the compression spring 19 compresses the two end plates 16 to move outward, thereby causing the drive wheel 21 on the drive rod 20 to move outward, which tightens the grinding belt 18. Then, the drive motor 25 in the drive component 10 drives the drive gear 26 to rotate, thereby causing the meshing gear 23 to rotate, which in turn causes the drive wheel 21 to drive the grinding belt 18 to start rotating. After contacting the side of the brake pad, the grinding and chamfering operation can be achieved.

[0036] For further details, please refer to [link / reference]. Figure 2 , Figure 5 and Figure 6The linkage part 11 includes a toothed plate 27 fixed to the bottom of the movable seat 1 and a linkage gear 28 disposed at the bottom of the movable seat 1. A docking shaft 29 is fixed inside the linkage gear 28. The two ends of the docking shaft 29 are fixed to the rotating shafts of the two rotating frames 8 through universal joints. The number of teeth of the toothed plate 27 is one-third of the number of teeth of the linkage gear 28. An angle positioning member 30 is disposed on the outside of the linkage gear 28.

[0037] In this solution, during the movement of the movable seat 1, the toothed plate 27 will come into contact with the linkage gear 28, and the linkage gear 28 will rotate 120°, thereby driving the rotating frame 8 to rotate 120° through the universal joint, replacing the new grinding part 9, and moving the worn grinding part 9 to other areas, making it convenient for personnel to replace the grinding belt 18.

[0038] It should also be noted that, see reference Figure 1 and Figure 2 Each grinding section 9 can grind two brake pads before replacement. The number of toothed plates 27 can be set to two. After grinding two brake pads each time, the toothed plate 27 meshes with the linkage gear 28. Therefore, the two toothed plates 27 can make the three grinding sections 9 rotate to the grinding area in turn. At the same time, the moving seat 1 can shorten its movement range by reciprocating.

[0039] For further details, please refer to [link / reference]. Figure 1 and Figure 2 as well as Figure 10 The locking component 3 includes a connecting rod 36 fixed on the mounting bracket 2. A pressure plate 37 is slidably sleeved on the outer side of the connecting rod 36, and a limit block is fixed on the top of the connecting rod 36. The brake pad is placed between the mounting bracket 2 and the pressure plate 37, and an inclined block is fixed on the outer end of the pressure plate 37. A compression spring 38 that abuts against the pressure plate 37 is sleeved on the outer side of the connecting rod 36. A protrusion that matches the groove on the brake pad is fixed on the mounting bracket 2. The protrusion is designed to limit the brake pad, and the inclined block is designed to allow personnel to push the brake pad directly in from one side.

[0040] In order to prevent the brake pads from coming into contact with the outside of the grinding belt 18 when they are first ground, a cavity 39 is provided in the movable seat 1. A rod 40 that slides through the cavity 39 is fixed at the bottom of the mounting bracket 2. An end block is fixed at the bottom of the rod 40, and a push spring 35 that pushes the rod 40 downward is sleeved on the outside of the rod 40.

[0041] In this scheme, the pressure spring 38 is used to make the pressure plate 37 abut against the outer side of the brake pad. When it moves to fit against the outer side of the grinding belt 18, the brake pad will be squeezed and pushed up. Under the action of the push spring 35, the mounting bracket 2 drives the brake pad to move down and fit tightly against the outer side of the grinding belt 18, and finally completes the grinding of the side chamfer.

[0042] This solution outlines the specific operational procedures for efficiently chamfering brake pads, including the following steps:

[0043] The first step is for personnel to install multiple brake pads into multiple locking components 3 in sequence;

[0044] The second step is to move the moving seat 1 through the moving mechanism, and move the brake pads to the grinding area to contact the grinding part 9 in sequence.

[0045] The third step is that after grinding a certain number of brake pads, the movement of the moving seat 1 will cause the toothed plate 27 to mesh with the linkage gear 28, so that the rotating frame 8 will move the new grinding part 9 to the contact recess 6 and start grinding the new brake pads.

[0046] In the fourth step, the old grinding section 9 is moved to other areas by the rotating frame 8. At this time, the drive rod 20 inside the grinding section 9 disengages from the contact recess 6 and moves to contact the inner wall of the adjusting ring 5, thereby causing the two end plates 16 to retract and no longer squeeze the grinding belt 18, making it convenient to replace the grinding belt 18.

[0047] Fifth, repeat steps two through four to change the grinding material without stopping the machine, thereby improving the efficiency of chamfering both sides of the brake pads.

[0048] In this scheme, when the drive rod 20 moves within the adjusting ring 5, the distance between the two end plates 16 is smaller than the distance between the two end plates 16 when the drive rod 20 moves within the contact recess 6. This makes the grinding belt 18, which was originally taut when it was in the contact recess 6, become a loose grinding belt 18 when it moves into the adjusting ring 5, making it convenient for personnel to replace the grinding belt 18.

[0049] Meanwhile, in this scheme, in order to facilitate the movement of the drive rod 20 within the adjusting ring 5 and the contact recess 6, a roller 24 that fits against the outer side of the adjusting ring 5 is fixed at the outer end of the drive rod 20. In order to make the rotating frame 8 more stable during rotation adjustment, a support tube 34 is fixed on the support plate 7. The support tube 34 is rotatably sleeved on the outer side of the rotating shaft of the rotating frame 8 and abuts against the inner wall of the rotating frame 8.

[0050] Example 2: Please refer to Figure 5 as well as Figure 6 This embodiment further explains Embodiment 1, the difference being the elaboration of one specific embodiment of the angle positioning member 30.

[0051] Specifically, the angle positioning component 30 includes an electric push rod 31, with a U-shaped frame 32 fixed to the top of the electric push rod 31. Three conical openings 33 are equally spaced on both sides of the linkage gear 28. The two ends of the U-shaped frame 32 are inserted into the conical openings 33 and fit against the inner wall. Each time the toothed plate 27 meshes with the linkage gear 28, the electric push rod 31 will drive the U-shaped frame 32 to move down and disengage from the conical openings 33.

[0052] In this scheme, after the linkage gear 28 is adjusted by the toothed plate 27 each time, in order to maintain the adjustment accuracy of the linkage gear 28 and ensure that the grinding part 9 can stably fit against the side of the brake pad, the electric push rod 31 is used to lift the U-shaped frame 32 into the conical opening 33. This ensures that the adjusted linkage gear 28 rotates 120° each time, so that the three grinding parts 9 can rotate in turn into the contact recess 6, improving the contact accuracy during grinding.
