Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to a surface grinding device for automotive brake pad backing plates. Background Technology

[0002] Automotive brake pads, also known as brake linings, are friction materials fixed to the brake drum or brake disc. The friction linings and friction blocks bear external pressure and generate friction to achieve the purpose of vehicle deceleration. Automotive brake pads are generally composed of a steel plate, an adhesive heat insulation layer, and friction blocks. When braking, they are pressed against the brake disc and generate friction with the brake disc, thereby achieving the purpose of vehicle deceleration and braking. After the brake pads are processed, the surface of the friction blocks will have uneven burrs. If they are installed on the vehicle without grinding, there will be certain risks. Therefore, the friction blocks need to be ground during processing.

[0003] Existing automotive brake pad backing plate surface grinding equipment has certain shortcomings in practical applications. In particular, during the grinding process, the high-speed friction between the backing plate material (such as steel) and the grinding disc or grinding cylinder generates a large amount of iron filings. These iron filings are easily scattered, not only polluting the working environment but also potentially being inhaled by workers, causing long-term health problems. Furthermore, since brake pad backing plates are usually mass-produced parts, the grinding workload is large, resulting in a significant accumulation of iron filings, making subsequent cleaning extremely cumbersome, increasing maintenance costs and time, and reducing production efficiency.

[0030] Example

[0031] Reference Figures 1-5 This embodiment provides a surface grinding device for automotive brake pad backplates, including a processing table 100, a grinding mechanism 200, and a dust collection mechanism 300, which aims to achieve efficient grinding of brake pad backplates, effective dust reduction and waste collection, and improve working environment safety and production efficiency.

[0032] The processing table 100, serving as the foundation platform of the entire equipment, is made of high-strength metal, possessing excellent stability and load-bearing capacity. Its flat upper surface is suitable for installing various functional components and provides a stable operating environment for grinding operations. The processing table 100 is equipped with a drainage channel 101 located directly below the dustproof frame 201, used to collect dust-laden liquids generated during the grinding process, preventing liquid spillage and contamination of the equipment or workshop environment, and ensuring the cleanliness and safety of the work area.

[0033] Specifically, the grinding mechanism 200 includes a dustproof frame 201 fixedly installed at the center of the top of the processing table 100. The dustproof frame 201 is made of transparent wear-resistant material, which can effectively isolate iron filings and dust generated during the grinding process, prevent them from flying to the outside, and facilitate the operator to observe the internal grinding situation in real time.

[0034] A fixed seat 202 is slidably connected to the bottom of the dustproof frame 201. The fixed seat 202 is connected to the processing table 100 and the interior of the dustproof frame 201 via a high-precision slide rail 207, ensuring stability and accuracy during the sliding process. A handle 202a is fixedly installed on the outer wall of the right end of the fixed seat 202, allowing workers to manually move the fixed seat 202 out of or into the dustproof frame 201, thereby simplifying the handling of the brake pad backing and improving loading and unloading efficiency. Four fixing grooves 202b are formed on the upper surface of the fixed seat 202. The shape of the fixing grooves 202b is precisely cast according to the shape of the automotive brake pad backing to be processed, ensuring that the brake pad can be firmly locked in the fixing grooves 202b with its surface to be ground facing upwards, facilitating precise processing by the grinding roller 204.

[0035] Four sets of drainage holes 202c are evenly distributed on the outer side of the fixed groove 202b. The bottom of the drainage holes 202c is connected to the drainage channel 101 inside the processing table 100, which can quickly guide the mixture of dust-suppressing liquid and iron filings sprayed during the grinding process to the collection component below, preventing liquid accumulation from affecting the grinding effect. A mounting bracket 203 is provided on the left side above the fixed base 202. The mounting bracket 203 is a sturdy metal frame used to support the grinding roller 204 and ensure its stability during high-speed rotation. The grinding roller 204 is rotatably connected inside the mounting bracket 203. The surface of the grinding roller 204 is covered with wear-resistant abrasive belt or grinding wheel material, which can efficiently remove burrs, oxide layers or uneven parts from the surface of the brake pad backing plate, ensuring a smooth and flat surface after grinding, meeting the high-precision requirements of brake pad assembly.

[0036] A drive assembly 205 is provided at the rear end of the grinding roller 204. The drive assembly 205 includes a support baffle 501 slidably connected to the rear wall of the dustproof frame 201. The support baffle 501 is made of high-strength steel plate, which not only seals the rear end of the dustproof frame 201 to prevent iron filings and dust from leaking out, but also provides stable limit support for the servo motor 503. The servo motor 503 is fixedly installed at the rear end of the support baffle 501 through a fixing bracket 502. The servo motor 503 has a high-precision control function and can adjust the speed according to the grinding requirements to ensure that the grinding roller 204 runs at the optimal speed, which improves grinding efficiency and avoids over-grinding and damage to the workpiece. The output end of the servo motor 503 is connected to the rotating shaft 504 via a coupling. The front end of the rotating shaft 504 passes through the support baffle 501 and extends into the mounting frame 203, where it is fixedly connected to the grinding roller 204. The rotating shaft 504 is rotatably connected to the inner wall of the support baffle 501 and the mounting frame 203 via high-precision bearings, ensuring smoothness and low friction loss during rotation. At the same time, it allows the servo motor 503 to be placed outside the dustproof frame 201, reducing the risk of dust corrosion to the motor and allowing the grinding roller 204 to move freely with the mounting frame 203.

[0037] The rear end of the mounting frame 203 is equipped with a pushing component 206. The pushing component 206 includes a support base 206a fixedly mounted on the upper surface of the processing table 100 and located outside the dustproof frame 201. The support base 206a is a sturdy metal base to ensure the stability of the electric cylinder 206b. The electric cylinder 206b is fixedly mounted on the upper surface of the support base 206a. A telescopic rod 206c is movably connected inside the electric cylinder 206b. The output end of the telescopic rod 206c passes through the outer wall of the dustproof frame 201 and extends into it, where it is fixedly connected to the left side wall of the mounting frame 203. Through the precise control of the electric cylinder 206b, the telescopic rod 206c can push the mounting frame 203 and the grinding roller 204 to move left and right, realizing the comprehensive grinding of the brake pad backplate in the fixed groove 202b. This achieves a high degree of automation, reduces manual operation, and improves production efficiency.

[0038] Furthermore, the dust collection mechanism 300 includes fixing rings 301 fixedly installed on the front and rear sides of the top of the dustproof frame 201. The fixing rings 301 are made of corrosion-resistant material to ensure stability during long-term use. An annular pipe 302 is fixedly installed between the two fixing rings 301. The annular pipe 302 has a hollow structure, allowing high-pressure water to flow inside. A water inlet pipe 303 is connected to its right side. The input end of the water inlet pipe 303 passes through the dustproof frame 201 and extends to its outside, connecting to an external water source to provide a stable water flow into the annular pipe 302. Multiple atomizing nozzles 304 are distributed in a circular array at the bottom of the annular pipe 302. The atomizing nozzles 304 can convert the water flow into fine water mist, which is evenly sprayed inside the dustproof frame 201, effectively adsorbing iron filings and dust generated during the grinding process, causing them to settle quickly, significantly reducing the dust concentration in the air, protecting the health of operators, and keeping the inside of the equipment clean.

[0039] Furthermore, the dust collection mechanism 300 also includes a collection component 305 disposed on the lower surface of the processing table 100. The collection component 305 includes fixing plates 305a fixedly installed on the left and right sides of the lower surface of the processing table 100. The fixing plates 305a are made of high-strength metal plates to ensure the stable installation of the collection frame 305b. The collection frame 305b is fixedly installed at the bottom end of the two fixing plates 305a. The collection frame 305b is located directly below the drainage channel 101 and is used to collect the mixture of dust-laden liquid and iron filings flowing down from the drainage hole 202c and the drainage channel 101, preventing waste from being directly discharged into the external environment. A filter frame 305c is movably installed on the upper side inside the collection frame 305b. The filter frame 305c adopts a fine filter screen design, which can effectively separate iron filings and impurities in the liquid, facilitating subsequent waste recycling and liquid recycling, and reducing resource waste. A drain outlet 305d is provided on the bottom right side of the collection box 305b. The drain outlet 305d is connected to the external drainage system, which can discharge the filtered liquid in an orderly manner, ensuring that the collection box 305b will not be affected by excessive liquid accumulation, thus ensuring normal operation.

[0040] Through the above design, the automotive brake pad backing surface grinding equipment of this embodiment can achieve efficient and precise grinding operations. Simultaneously, the dustproof frame 201 and dust collection mechanism 300 effectively control the flying of iron filings and dust, significantly improving the working environment and reducing threats to operator health. The sliding design of the fixed base 202 and the arrangement of the handle 202a simplify the workpiece loading and unloading process. The cooperation between the drainage channel 101 and the collection component 305 facilitates the centralized treatment of waste and liquids, reducing subsequent cleaning hassles and greatly improving production efficiency and equipment maintenance convenience in mass production environments.
