Description

Technical Field

[0001] The present invention belongs to the field of brake pad grinding, and particularly relates to a multi-directional integrated grinding machine. Background Art

[0002] The brake pad is also called the brake lining. In the braking system of an automobile, the brake pad is the most crucial safety component, and the quality of all braking effects is determined by the brake pad.

[0003] After the brake pad is connected to the steel back, it is also necessary to grind the working surface and two side arc surfaces of the brake pad one by one in sequence through a grinding machine. During the grinding process of each surface, a fixture is required to clamp and fix the brake pad, and a total of three fixtures are needed, resulting in a reduction in the grinding efficiency of the grinding machine for the brake pad.

[0004] During the grinding process of the brake pad by the grinding machine, a large amount of heat will be generated between the grinding tool and the brake pad, which will affect the grinding efficiency and quality and cause serious wear of the grinding tool.

[0005] During the design of the grinding machine, it is found that the brake pads formed by mixing and pressing multiple raw materials will generate granular waste after being ground. If the generated granular waste is not removed in time, it will aggravate the wear of the grinding tool.

[0006] The present invention designs a multi-directional integrated grinding machine to solve the above problems. Summary of the Invention

[0061] In a further embodiment, as Figure 4 shown, the telescopic rod B212 is composed of an outer sleeve B213 and an inner rod B215 sleeved with each other, and a spring B214 is located within the outer sleeve B213; the spring B214 is a tension spring.

[0062] In a further embodiment, as Figure 4 、 6 shown, the clamping seat 223 includes a collar H216, a screw 217, a nut sleeve A218, a torsion wheel 219, a mounting plate 220, a nut sleeve B221, and a bolt 222. As Figure 4 、 6 shown, two vertically axis collars H216 are installed at the end of the inner rod B215 of the telescopic rod B212, and the axis connection line of the two collars H216 is horizontally perpendicular to the corresponding telescopic rod B212; a screw 217 is installed within each collar H216. A nut sleeve A218 rotatably nested within the collar H216 is threadedly connected to the screw 217. A torsion wheel 219 is installed at the upper end of the screw 217.

A mounting plate 220 that is connected to the steel back 103 of the brake pad 104 through a bolt 222 is installed on the nut sleeve B221.

[0063] As Figure 1 、 4 shown, the telescopic rod A422 is installed on the disc B421 at the upper end of the bushing 401 to ensure that as many telescopic rods A422 as possible can be installed on the bushing 401.

[0064] As Figure 1 、 4 shown, the telescopic rod B212 is installed on the disc C211 at the upper end of the rotating shaft 201 to ensure that as many telescopic rods B212 as possible can be installed on the rotating shaft 201.

[0065] The working principle and process of the present invention are as follows:

[0066] In the initial state, no mounting plate 220 is installed at the end of each telescopic rod B212. All telescopic rods A422 and all telescopic rods B212 are in the extreme contraction state, and the springs A424 in the telescopic rods A422 and the springs B214 in the telescopic rods B212 are in the stretched state.

[0067] When it is necessary to grind the inner and outer arc surfaces and the working surfaces of the same model and batch of brake pads 104 of the present invention, first select a matching mounting plate 220 according to the model of the brake pads 104. After installing the mounting plate 220 at the end of each telescopic rod B212, install the brake pads 104 on the mounting plate 220 through bolts 222.

[0068] The process of installing the mounting plate 220 on the two screws 217 at the end of the corresponding telescopic rod B212 is as follows:

[0069] Align the two nut sleeves B59 on the mounting plate 220 with the two screws 217 at the end of the corresponding telescopic rod B212 one by one. Rotate the two screws 217 respectively through the torsion wheels 219, so that the two screws 217 are respectively screwed into the corresponding nut sleeves B59 on the mounting plate 220 to complete the installation of the mounting plate 220 at the end of the telescopic rod B212. After the installation of the mounting plate 220 is completed, adjust the height of the mounting plate 220 by rotating the nut sleeves A218 on the two ring sleeves H216 at the end of each telescopic rod B212, so that the heights of the mounting plates 220 at the ends of all telescopic rods B212 are equal.

[0070] After the installation of the brake pads 104 on the mounting plate 220 is completed by connecting each mounting plate 220 to the steel back 103 on the brake pads 104 through bolts 222, start the motor B207 to drive the rotating shaft 201 to rotate at a certain speed. At the same time, start the air pump connected to the air pipe A307 on the disc A301. The rotating shaft 201 drives the brake pads 104 at the ends of all telescopic rods B212 to rotate around the axis of the disc A301 at a certain speed. All telescopic rods B212 extend under the centrifugal force, and the springs B214 in the telescopic rods B212 are further stretched, so that the brake pads 104 installed at the ends of the telescopic rods B212 are exactly within the grinding range of all grinding modules A302 on the disc A301.

[0071] Then, start the two electric push rods B210 to drive the rotating shaft 201 to move vertically downward. The rotating shaft 201 drives all the brake pads 104 on all telescopic rods B212 to move downward by a certain amplitude, so that the working surfaces of all the brake pads 104 interact with all the grinding modules A302 on the disc A301 in turn and are effectively ground by the grinding modules A302.

[0072] After the working surface of the brake pad 104 is roughly ground by the grinding block A303 in the grinding module A302, it is finely ground by the grinding block B304 on the grinding module A302. The grinding debris generated by the fine grinding of the working surface of the brake pad 104 by the grinding block B304 is cleaned by the brush group A305 in the grinding module A302, thereby reducing the wear when the next grinding module A302 interacts with the working surface of the brake pad 104.

[0073] During the process of the working surface of the brake pad 104 moving downward to the next grinding module A302 after leaving the brush group A305 of the grinding module A302, the dense air blowing holes A308 between the two grinding modules A302 blow cold air to the working surface of the brake pad 104 due to the cold air sent into the air cavity A306 by the air pump through the air pipe A307, thereby effectively cooling the working surface of the brake pad 104 and facilitating the next grinding module A302 to further and more effectively polish the working surface of the brake pad 104.

[0074] After the grinding thickness of the brake pad 104 reaches the requirement, start two electric push rods B210 to drive the rotating shaft 201 to move vertically upward to reset and separate from the grinding module A302 on the disc A301. Then, stop the operation of the motor B207 so that all the brake pads 104 stop rotating. As the rotating shaft 201 stops rotating, all the telescopic rods B212 contract and reset under the action of the corresponding springs B214.

[0075] Next, start two electric push rods A411 to drive the bushing 401 and the ring B413 to move vertically upward synchronously by a certain amplitude, so that the ring B413 is located within the height range of the outer arc surface of the brake pad 104 and drives all the grinding modules C426 to move to the height range of the inner arc surface of the brake pad 104 through all the telescopic rods A422 on the bushing 401.

[0076] Then, first start the motor B207. The motor B207 drives the rotating shaft 201 to rotate. The rotating shaft 201 drives all the telescopic rods B212 to rotate synchronously. All the telescopic rods B212 extend under the centrifugal force. The telescopic rods B212 drive the brake pad 104 to move by a certain amplitude, so that the grinding module B414 on the inner wall of the ring B413 polishes the outer arc surface of the brake pad 104. After the grinding module B414 on the inner side of the ring B413 polishes the outer arc surface of the brake pad 104, start the motor A407. The motor A407 drives the bushing 401 to rotate. The rotation direction of the bushing 401 is opposite to the rotation direction of the rotating shaft 201. The bushing 401 drives all the telescopic rods A422 to rotate synchronously. All the telescopic rods A422 extend under the centrifugal force. The telescopic rods A422 drive the grinding module C426 to polish the inner arc surface of the brake pad 104.

[0077] During the process of grinding the inner and outer arc surfaces of the brake pad 104, two electric push rods A411 are reciprocally started, so that the two electric push rods A411 drive the ring B413 and all the grinding modules C426 to move vertically in a synchronous and equal-height reciprocating manner, and the grinding module B414 on the ring B413 and all the grinding modules C426 move vertically within the height range of the inner and outer arc surfaces of the brake pad 104, so that the inner and outer arc surfaces of the brake pad 104 are comprehensively ground.

[0078] During the process of grinding the inner and outer arc surfaces of the brake pad 104, the outer arc surface of the brake pad 104 is rough-ground by the grinding block C415 in the grinding module B414 and then finely ground by the grinding block D416 on the grinding module B414. The grinding chips generated by the fine grinding of the outer arc surface of the brake pad 104 by the grinding block D416 are cleaned by the brush group B417 in the grinding module B414, thereby reducing the wear when the next grinding module B414 interacts with the outer arc surface of the brake pad 104.

[0079] During the process of the outer arc surface of the brake pad 104 moving downward to the next grinding module B414 after separating from the brush group B417 of the grinding module B414, the dense air blowing holes B between the two grinding modules B414 blow cold air to the outer arc surface of the brake pad 104 due to the cold air sent into the air cavity B418 by the air pump through the air pipe B419, thereby effectively cooling the outer arc surface of the brake pad 104 and facilitating the next grinding module B414 to further and more effectively grind the outer arc surface of the brake pad 104.

[0080] During the process of grinding the inner and outer arc surfaces of the brake pad 104, the inner arc surface of the brake pad 104 is rough-ground by the grinding block E427 in the grinding module C426 and then finely ground by the grinding block F428 on the grinding module C426. The grinding chips generated by the fine grinding of the inner arc surface of the brake pad 104 by the grinding block F428 are cleaned by the brush group C429 in the grinding module C426, thereby reducing the wear when the next grinding module C426 interacts with the inner arc surface of the brake pad 104.

[0081] After the grinding of the inner and outer arc surfaces of the brake pad 104 is completed, the operation of the motor A407 and the motor B207 is stopped, so as to stop the rotation of all the telescopic rods A422 and all the telescopic rods B212. All the telescopic rods A422 contract and reset under the reset action of the corresponding springs A424, and all the telescopic rods B212 contract and reset under the reset action of the corresponding springs B214. Then, all the brake pads 104 can be removed.

[0082] In summary, the beneficial effects of the present invention are as follows: The present invention installs a batch of brake pads 104 through the end mounting plate 220 of the telescopic rod B212 evenly distributed in the circumferential direction on the rotating shaft 201 for grinding the brake pads 104. First, the working surface of the brake pads 104 is ground, and then the two side arc surfaces of the brake pads 104 are ground simultaneously. The clamping method of the brake pads 104 does not need to be changed during the whole grinding process, effectively improving the grinding efficiency of the brake pads 104.

[0083] In the present invention, a group of air blowing holes A308 between any two adjacent grinding modules A302 on the disc A301 and a group of air blowing holes B420 between any two adjacent grinding modules B414 on the inner side of the ring B413 will clean the particulate waste generated on the three ground surfaces of the brake pads 104 and effectively cool and lower the temperature of the ground parts of the brake pads 104, improving the grinding efficiency and quality of the brake pads 104 and protecting the grinding modules A302, B414 and C426 from serious wear due to excessive temperature.

[0084] In the present invention, the grinding blocks A303 and B304 in the grinding module A302 on the disc A301, the grinding blocks C415 and D416 in the grinding module B414 on the inner side of the ring B413, and the grinding blocks E427 and F428 in the grinding module C426 can achieve the grinding of the brake pads 104 from coarse to fine, reducing the wear of the grinding blocks A303 in the grinding module A302, the grinding blocks C415 in the grinding module B414 on the inner side of the ring B413, and the grinding blocks E427 in the grinding module C426 and improving the grinding accuracy of the brake pads 104. At the same time, the brush groups A305 in the grinding module A302 on the disc A301, the brush groups B417 in the grinding module B414 on the inner side of the ring B413, and the brush groups C429 in the grinding module C426 can clean the particulate waste on the three ground surfaces of the brake pads 104, reducing the roughness of the working surface and the two side arc surfaces of the brake pads 104 after grinding, and further reducing the wear of the grinding blocks A303 and B304 in the grinding module A302 on the disc A301, the grinding blocks C415 and D416 in the grinding module B414 on the inner side of the ring B413, and the grinding blocks E427 and F428 in the grinding module C426.

[0085] The present invention grinds a batch of brake pads 104 of the same model, and can achieve the full grinding of the three surfaces of the brake pads 104 after clamping the batch of brake pads 104 once, thereby improving the grinding efficiency of the brake pads 104.
