Description

[0002] As a crucial component for braking automobile wheels, automotive brake pads are subject to extremely stringent quality requirements during their production. Drum brake pads, with their curved, arc-shaped structure, require grinding of both the inner and outer arc surfaces during manufacturing to create a smooth surface. This ensures excellent braking performance and enhances driving safety.

[0003] Existing equipment cannot grind the inner and outer curved surfaces of brake pads simultaneously; it can only grind them one by one, which not only takes a long time but also results in low work efficiency.

[0004] Furthermore, during the rough grinding process, the mounting groove of the brake pads cannot be ground, leaving burrs on the mounting groove and some debris flying into it. To ensure the subsequent installation of the brake pads, the burrs need to be scraped off manually and the debris in the mounting groove needs to be removed. This is not only time-consuming but also inefficient. Summary of the Invention

[0016] A method for using an environmentally friendly grinding device for processing automotive brake pads includes the following steps:

[0017] Step 1: The operator places the brake pad into the arc-shaped groove of the limiting cylinder, and then the ring plate rotates the brake pad counterclockwise. During the rotation, the inner and outer arc surfaces of the brake pad are roughly polished by electric grinding roller one and electric grinding roller three.

[0018] Step 2: After the brake pad moves to the left side of the limiting cylinder, control the external compressor to deliver high-pressure gas. The high-pressure gas pushes the boss into the mounting groove of the brake pad. The flow rate of the high-pressure gas drives the boss and the fan blade to rotate. Several protrusions on the outer ring surface of the boss scrape off the burrs in the mounting groove of the brake pad.

[0019] Step 3: After the burrs in the brake pad mounting groove are scraped off, turn on the external fan to ventilate the brake pad mounting groove and blow away the debris and burrs.

[0020] Step 4: After the mounting slot of the brake pad is cleaned, the brake pad is rotated clockwise by the ring plate. During the rotation, the inner and outer arc surfaces of the brake pad are finely polished by electric grinding roller 2 and electric grinding roller 4.

[0021] Step 5: During the polishing process, use protective covers one and two to collect the debris that flies around during polishing. At the same time, scrape the debris at the bottom of protective covers one and two into the corresponding boxes.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] The present invention provides an environmentally friendly grinding device for processing automotive brake pads, which uses two electric grinding rollers (first and third) to coarsely grind the inner and outer curved surfaces of the brake pads, and then uses two electric grinding rollers (second and fourth) to finely grind the inner and outer curved surfaces of the brake pads, so that the inner and outer curved surfaces of the brake pads are smooth, meeting the requirements of braking friction and improving the efficiency of brake pad grinding.

[0024] The present invention provides an environmentally friendly grinding device for processing automotive brake pads. High-pressure gas forces the boss into the mounting groove of the brake pad. Simultaneously, the high-pressure gas drives the boss to rotate, causing the raised strips on the outer circumference of the boss to contact the burrs in the mounting groove of the brake pad, scraping them off. Airflow then blows the debris and burrs from the mounting groove into the inner wall of the circular tube, eliminating the need for manual scraping and cleaning of burrs and debris in the mounting groove. This not only saves manpower and time but also improves work efficiency.

[0025] The present invention provides an environmentally friendly grinding device for processing automotive brake pads. Protective covers one or two protectors enclose the working electric grinding rollers (one, two, three, or four) to prevent grinding debris from flying everywhere and being inhaled by the human body, thus preventing harm. A scraper continuously rotates to remove debris accumulated at the bottom of the corresponding protective cover one or two, preventing excessive debris buildup that could prevent the corresponding electric grinding rollers one, two, three, or four from rotating.

[0051] The power assembly includes a fixed plate 101, a motor 102, a connecting cylinder 103, a connecting plate 104, and an annular plate 105; the fixed plate 101 is fixedly connected to the front side of the mounting bracket 7; the motor 102 is bolted to the upper surface of the fixed plate 101; the output shaft of the motor 102 is fixedly connected to the connecting cylinder 103; two connecting plates 104 are fixedly connected to the outer annular surface of the connecting cylinder 103; the two connecting plates 104 are jointly fixedly connected to the annular plate 105; the annular plate 105 is provided with a notch, which is adapted to the brake pad 10; the annular plate 105 is slidably disposed in the arc-shaped groove 2a.

[0052] The feeding assembly includes a limiting ring 201, an electric push rod 202, a connecting plate 203, a round rod 204, and an arc plate 205. A feeding groove 2b is provided on the upper surface of the limiting cylinder 2. A limiting ring 201 is fixedly connected to the upper and lower inner walls of the arc groove 2a for positioning the brake pad 10. A limiting part 201a is provided on the left and right sides of each limiting ring 201. A clearance groove 1a is provided on the base frame 1. An electric push rod 202 is fixedly connected to the clearance groove 1a. A connecting plate 203 is fixedly connected to the telescopic part of the electric push rod 202. Two round rods 204 are fixedly connected to the connecting plate 203. The two round rods 204 penetrate the base frame 1. The arc plate 205 is fixedly connected to both round rods 204. The arc plate 205 is inserted into the limiting cylinder 2.

[0053] The switching assembly includes an electric push rod 301, a round rod 302, a transmission plate 303, and an electric push rod 304. Two electric push rods 301 are hinged to each mounting bracket 3. One round rod 302 is fixed to each I-beam mounting bracket 4. The telescopic parts of all electric push rods 301 on the same mounting bracket 3 are rotatably connected to the round rod 302 on the same mounting bracket 3. Two transmission plates 303 are rotatably connected to each electric grinding roller 6. The transmission plate 303 of the left electric grinding roller 6 is rotatably connected to the left electric grinding roller 8. The transmission plate 303 of the right electric grinding roller 6 is rotatably connected to the right electric grinding roller 8. Two electric push rods 304 are bolted to the middle of the mounting bracket 7. The two electric push rods 304 are rotatably connected to the electric grinding roller 9 via connecting blocks.

[0054] The rotation described below refers to rotations from front to back, top to bottom, and right to left. In use, first place this environmentally friendly automotive brake pad grinding device in the desired position. Existing equipment cannot simultaneously grind the inner and outer curved surfaces of the brake pad 10; it can only grind them sequentially. This results in long working times and low efficiency. Therefore, the operator controls the two electric grinding rollers 5 and 8 to rotate clockwise. Then, the brake pad 10 is placed from the feed chute 2b into the arc-shaped groove 2a of the limiting cylinder 2. The brake pad 10 will fall onto the arc-shaped plate 205. The electric push rod 202 is then pushed out, causing the connecting plate 203, the round rod 204, the arc-shaped plate 205, and the brake pad 10 to move downwards together, allowing the brake pad 10 to move into the notch of the ring plate 105. Figure 3 As shown, the output shaft of motor 102 is then controlled to rotate counterclockwise, causing connecting cylinder 103, connecting plate 104, ring plate 105, and brake pad 10 to rotate together. Under the restriction of the two limit rings 201, the brake pad 10 moves out of the arc groove 2a and continues to move towards the electric grinding roller 5. During the movement, the brake pad 10 will contact the two electric grinding rollers 5 and the two electric grinding rollers 8 in sequence. Figure 6 As shown in the lower state diagram, the inner and outer arc surfaces of the brake pad 10 are roughly polished by two electric polishing rollers 5 and 8. After the brake pad 10 passes through the polishing of the two electric polishing rollers 5 and 8, it comes to the left of the limiting cylinder 2 and comes into contact with the limiting part 201a on the left of the limiting ring 201. The polishing of the inner and outer arc surfaces of the brake pad 10 is completed, the output shaft of the control motor 102 stops rotating, and the electric polishing rollers 5 and 8 stop rotating.

[0055] Simultaneously, the electric push rod 301 retracts, forcing the I-beam mounting bracket 4 to rotate around its own axis via the round rod 302. This causes the electric grinding roller 5 and electric grinding roller 6 to slide within the corresponding arc-shaped groove 3a, moving electric grinding roller 5 away from the outer arc surface of the brake pad 10 and electric grinding roller 6 closer to the outer arc surface of the brake pad 10. Simultaneously, as electric grinding roller 6 moves, it pushes electric grinding roller 8 through the transmission plate 303 to slide within the corresponding straight groove 7a, moving both electric grinding rollers 8 away from the inner arc surface of the brake pad 10. Then, the two electric push rods 304 are pushed out, bringing the connecting block and electric grinding roller 9 closer to the inner arc surface of the brake pad 10. Figure 6In the state diagram above, the electric grinding rollers 2 and 4 rotate counterclockwise, while the output shaft of motor 102 rotates clockwise, causing the connected components and brake pad 10 to rotate together. The electric grinding rollers 2 and 4 perform fine grinding on the inner and outer curved surfaces of the brake pad 10, smoothing them to meet braking friction requirements and improving grinding efficiency. After the brake pad 10 passes through the electric grinding rollers 2 and 4, the grinding rollers... When the grinding roller 49 reaches the right side of the limiting cylinder 2 and contacts the limiting part 201a on the right side of the limiting ring 201, and is positioned above the arc plate 205, the output shaft of the control motor 102 stops rotating. Then, the electric grinding roller 26 and the electric grinding roller 49 stop rotating. Next, the electric push rod 1 202 is pushed out, driving the connected components and brake pad 10 to move upward, so that the upper part of the brake pad 10 moves out of the arc groove 2a, making it easier for the operator to remove the finished brake pad 10. Then, all components are reset.

[0058] It also includes a blow-off assembly; two blow-off assemblies are connected to the left side of the inner ring surface of the limiting cylinder 2, and the two blow-off assemblies are symmetrically distributed vertically; the blow-off assembly includes a cover 409, an electric push rod 410, a cover plate 411, and an arc block 412; the cover 409 is fixedly connected to the upper left side of the inner ring surface of the limiting cylinder 2; the cover 409 has an air inlet 409a at the top; two electric push rods 410 are bolted to the right side of the cover 409; the telescopic parts of the two electric push rods 410 are fixedly connected to the cover plate 411; the cover plate 411 is slidably connected to the cover 409; the arc block 412 is fixedly connected to the cover plate 411, and the arc block 412 is slidably connected to the limiting cylinder 2; multiple semi-circular grooves 412a are opened on the arc block 412.

[0059] The left side of the inner ring surface of the limiting cylinder 2 has several round holes 2c. After the two arc blocks 412 are combined, the multiple semi-circular grooves 412a on the upper side and the multiple semi-circular grooves 412a on the lower side form multiple round grooves. The number of round holes 2c and multiple round grooves are matched with the number of mounting grooves of the brake pad 10 and are equal in size.

[0060] The operator connects an external compressor to the intake pipe 401a and an external fan to the air inlet 409a. Because burrs remain on the mounting groove of the brake pad 10 during the rough grinding process, and some debris flies into the mounting groove, manual scraping of the burrs and removal of debris from the mounting groove are necessary to ensure subsequent installation of the brake pad 10. This process is time-consuming and inefficient. Therefore, after the brake pad 10 moves to contact the limiting part 201a on the left side of the limiting ring 201, the mounting groove on the brake pad 10 aligns with several circular pipes 402, and then the external compressor is controlled... When the compressor starts, it delivers high-pressure gas into the distributor 401. The high-pressure gas is then distributed through the distributor 401 to several circular tubes 402. Upon entering the circular tubes 402, the high-pressure gas forces the slip ring 404, boss 405, fan blade 406, L-shaped slide rod 407, and sealing plate 408 to move towards the corresponding brake pad 10 mounting slots. The elastic element 403 is forced to stretch, and the slip ring 404 slides on the inner wall of the circular tube 402. During its movement, the L-shaped slide rod 407 contacts the outer arc surface of the brake pad 10, forcing it to slide on the slip ring 404. 7. The sealing plate 408 is moved away from the slip ring 404, no longer sealing the through hole of the slip ring 404, allowing high-pressure gas to be discharged from the through hole of the slip ring 404 and the internal channel of the boss 405. The fan blade 406, under the action of the continuously flowing high-pressure gas, will drive the boss 405 to rotate on the slip ring 404. When the boss 405 enters the mounting groove of the brake pad 10, the protrusion on the outer ring surface of the boss 405 fits into the mounting groove of the brake pad 10, and the end of the boss 405 passes through the mounting groove of the brake pad 10. Through the protrusion on the outer ring surface and the continuously rotating boss 405, the brake pad 10 is installed... The burrs in the mounting groove are scraped off, saving the need for manual scraping of the burrs in the mounting groove and improving work efficiency. After the boss 405 rotates for a period of time, the external compressor is controlled to shut down, and high-pressure gas is no longer delivered to the distributor 401. Under the action of the elastic element 403, the slip ring 404, boss 405, fan blade 406, L-shaped slide bar 407 and sealing plate 408 are driven to disengage from the mounting groove of the brake pad 10. After the elastic element 403 drives the connected parts to reset, the sealing plate 408 closes the through hole of the slip ring 404 again. A small amount of debris and burrs are still left in the mounting groove of the brake pad 10.

[0061] At the same time, the four electric push rods 410 are pushed out, causing the upper cover plate 411 and the arc block 412 to move towards each other with the lower cover plate 411 and the arc block 412, so that the two cover plates 411 and the two arc blocks 412 fit together, so that the two covers 409, the two cover plates 411 and the two arc blocks 412 form a sealing cover. At the same time, the two arc blocks 412 merge to form multiple circular grooves. Then, the external fan is turned on to blow air into the sealing cover. After the gas in the sealing cover increases to the limit, the gas is discharged from several circular holes 2c and multiple circular grooves into the mounting groove of the brake pad 10. The airflow blows the debris and burrs in the mounting groove of the brake pad 10 into the inner wall of the circular tube 402, saving manpower and time and improving work efficiency. After the small amount of debris and burrs remaining in the mounting groove of the brake pad 10 are blown away, the external fan is turned off.

[0062] After the brake pad 10 leaves the right side of the limiting cylinder 2, the external compressor is restarted to deliver high-pressure gas into the distributor 401. The high-pressure gas forces the slip ring 404, boss 405, fan blade 406, L-shaped slide bar 407 and sealing plate 408 to move, allowing the boss 405 to insert into the corresponding number of round holes 2c and multiple round grooves. Meanwhile, the slip ring 404 moves along the inner wall of the round tube 402, carrying out the debris and burrs on the inner wall of the round tube 402. This prevents the slip ring 404 from being stuck by the debris and burrs remaining in the round tube 402 when the mounting groove of the brake pad 10 is scraped off later, which would prevent it from working properly. After the debris and burrs on the inner wall of the round tube 402 are cleared, all components are reset.

[0063] Example 3

[0064] Based on Example 2, such as Figure 11-14As shown, it also includes protective components; protective components are connected to the I-beam mounting frame 4 and the second mounting bracket 7; the protective components include a drainer 501, an air inlet pipe 502, a first protective cover 503, a limiting rod 506, and a second protective cover 507; a drainer 501 is fixedly connected to the middle of each I-beam mounting frame 4; each drainer 501 is provided with two air guides 501a, which face the first electric grinding roller 5 and the second electric grinding roller 6 respectively; an air inlet pipe 502 is connected to the rear of each drainer 501, and the air inlet pipe 502 passes through the first mounting bracket 3; a first protective cover 503 is fixedly connected to each drainer 501, and the first protective cover 503 covers the first electric grinding roller 5 and the second electric grinding roller 6; a rubber roller is rotatably connected to each side of each first protective cover 503. 503a, rubber roller 503a is used to intercept the debris generated during the grinding process and prevent the debris from splashing out of the protective cover 503; each protective cover 503 has a slag discharge port 503b at its lower part; several limiting rods 506 are slidably connected to the mounting bracket 7; every two limiting rods 506 form a group, and the two limiting rods 506 in the same group are fixed together to a protective cover 507; the three protective covers 507 respectively cover two electric grinding rollers 8 and one electric grinding roller 9; each protective cover 507 has a rubber roller 507a rotatably connected to each side, and the rubber roller 507a is used to intercept the debris generated during the grinding process and prevent the debris from splashing out of the protective cover 507; each protective cover 507 has a slag discharge port 507b at its lower part.

[0065] It also includes anti-clogging components; each protective cover 503 and each protective cover 507 is connected to an anti-clogging component; the anti-clogging components are connected to mounting bracket 3 and mounting bracket 7; the anti-clogging components include a guide plate 504, a scraper 505, a collection box 508, a collection box 509, and a trapezoidal box 510; a guide plate 504 is welded to the lower part of each protective cover 503 and the lower part of each protective cover 507; each electric grinding roller 5 and electric grinding roller 6 Each of the electric grinding rollers 3 and 4 has a scraper 505 fixedly attached to its lower part; each scraper 505 is fitted with a corresponding protective cover 1 503 or protective cover 2 507; the lower part of the mounting bracket 2 7 has a guide groove 7b, which is lower on the left and higher on the right; a collection box 1 508 is placed on the left side of the mounting bracket 2 7; a collection box 2 509 is placed on the opposite side of each of the two mounting brackets 1 3; a trapezoidal box 510 is placed on the opposite side of the two mounting brackets 1 3.

[0066] When the operator connects an external fan to the air inlet duct 502, a large amount of debris is generated when the electric grinding rollers 15 and 38 grind the brake pads 10. If this debris is not intercepted, it will fly everywhere, not only contaminating the equipment and increasing the workload for operators, but also posing a health hazard if inhaled. Therefore, a protective cover 503 is used to cover the electric grinding roller 15 during the grinding process, intercepting the debris generated and preventing it from flying everywhere and being inhaled. The debris is absorbed by the body and causes harm to the human body. At the same time, the rubber roller 503a of the protective cover 503 also contacts the outer arc surface of the brake pad 10. When the brake pad 10 rotates, it will drive the rubber roller 503a to rotate on the protective cover 503. The rubber roller 503a seals the gap between the protective cover 503 and the outer arc surface of the brake pad 10, so that the debris falls into the protective cover 503. This prevents the debris from passing through the gap and falling to the outside of the protective cover 503, contaminating the equipment and increasing the subsequent cleaning work of the operator.

[0067] It should be noted that: when the electric grinding roller 5 rotates, the external fan will be turned on, blowing air into the guide tube 501 through the air inlet pipe 502. After the airflow enters the guide tube 501, the air guide port 501a on the side of the guide tube 501 facing the electric grinding roller 5 will be opened, blowing air onto the part of the outer arc surface of the brake pad 10 that contacts the electric grinding roller 5, blowing away the debris remaining on the outer arc surface of the electric grinding roller 5 and the brake pad 10 after grinding, avoiding... To prevent residual debris from affecting subsequent grinding of the outer arc surface of the brake pad 10, the electric grinding roller 5 rotates, driving the scraper 505 below to rotate as well. By continuously rotating the scraper 505, the debris at the bottom of the protective cover 503 is discharged from the slag discharge port 503b into the guide plate 504, and then flows into the collection box 509 along the guide plate 504. This prevents a large amount of debris from accumulating at the bottom of the protective cover 503, which would affect the normal rotation of the electric grinding roller 5.

[0068] During the grinding process of the electric grinding roller 38 on the inner arc surface of the brake pad 10, the protective cover 2507 covers the electric grinding roller 38, intercepting the debris generated by the electric grinding roller 38 and preventing it from flying everywhere and being inhaled by the human body, thus preventing harm. At the same time, the two rubber rollers 2507a of the protective cover 2507 also contact the inner arc surface of the brake pad 10. When the brake pad 10 rotates, it will drive the rubber rollers 2507a to rotate on the protective cover 2507, sealing the gap between the protective cover 2507 and the inner arc surface of the brake pad 10. All debris falls inside the second protective cover 507, preventing it from passing through gaps and falling onto the outside of the second protective cover 507, contaminating the equipment, and increasing the subsequent cleaning work for operators. When the electric grinding roller 8 rotates, it drives the scraper 505 below to rotate as well. The scraper 505 discharges the debris at the bottom of the second protective cover 507 from the slag discharge port 507b into the guide plate 504, and then flows along the guide plate 504 into the guide groove 7b, allowing the debris to enter the first collection box 508 along the guide groove 7b. This prevents a large amount of debris from accumulating at the bottom of the second protective cover 507, which would affect the normal rotation of the electric grinding roller 8.

[0069] When the electric grinding roller 26 and the electric grinding roller 49 grind the brake pad 10, in accordance with the above working method, the debris generated during the grinding process by the electric grinding roller 26 and the electric grinding roller 49 is intercepted by the protective cover 1 503 and the protective cover 2 507 to prevent the debris from flying everywhere and being absorbed by the human body, causing harm to the human body. At the same time, the debris accumulated in the protective cover 1 503 and the protective cover 2 507 is scraped into the trapezoidal box 510 for collection.

[0070] A method for using an environmentally friendly grinding device for processing automotive brake pads includes the following steps:

[0071] Step 1: The operator places the brake pad 10 into the arc groove 2a of the limiting cylinder 2, and then rotates the brake pad 10 counterclockwise through the ring plate 105. During the rotation, the inner and outer arc surfaces of the brake pad 10 are roughly polished by the electric grinding roller 1 5 and the electric grinding roller 3 8.

[0072] Step 2: After the brake pad 10 moves to the left side of the limiting cylinder 2, control the external compressor to deliver high-pressure gas. The high-pressure gas pushes the boss 405 into the mounting groove of the brake pad 10. The flow rate of the high-pressure gas drives the boss 405 and the fan blade 406 to rotate. Several protrusions on the outer ring surface of the boss 405 scrape off the burrs in the mounting groove of the brake pad 10.

[0073] Step 3: After the burrs in the mounting groove of the brake pad 10 are scraped off, turn on the external fan to ventilate the mounting groove of the brake pad 10 and blow away the debris and burrs in the mounting groove of the brake pad 10.

[0074] Step 4: After the mounting groove of the brake pad 10 is cleaned, the brake pad 10 is rotated clockwise by the ring plate 105. During the rotation, the inner and outer arc surfaces of the brake pad 10 are finely polished by the electric polishing roller 2 6 and the electric polishing roller 4 9.

[0075] Step 5: During the polishing process, use protective covers 503 and 507 to collect the debris that flies around during polishing. At the same time, scrape the debris at the bottom of protective covers 503 and 507 into the corresponding boxes.
