Description

Technical Field

[0002] Brake pads are one of the key components in the automotive braking system, mainly used to generate friction to slow down or stop the movement of the vehicle. Brake pad cutting is an important process in the automotive repair and manufacturing process, involving the precise cutting of raw materials into the required shape and size. Commonly used cutting methods include laser cutting, water jet cutting and precision mechanical cutting, which can provide high-precision and high-quality cutting effects.

[0003] When cutting the brake pad, first place the brake pad material on the cutting platform and use a clamp to fix the material on the platform to ensure that the material does not move during the cutting process. Then mark the cutting line on the material for precise positioning and ensure that the material and the cutting path are aligned to avoid deviation. When cutting, first cut the outer contour of the brake pad to ensure the accuracy of the shape and size, and then cut the inner contour of the brake pad, such as grooves, holes, etc., to accurately cut the raw material into the required shape and size.

[0004] In actual use of the prior art, when cutting the brake pad, usually the outer contour of the brake pad is cut first, then the inner contour of the brake pad is cut, and finally the holes in the details are opened.

[0020] Compared with the prior art, the advantages of the present invention are:

[0021] (1) This solution realizes automatic transmission of brake pad materials by starting the conveying motor to drive the conveying rollers and conveyor belts, thereby reducing manual operations and improving production efficiency. When the conveyor belt transports the brake pad materials from the entrance to the cutting area, the electric push rod is started to drive the positioning plate to move downward to squeeze and fix the brake pad materials, ensuring that the materials will not move during the cutting process, thereby improving the stability and accuracy of the cutting. The support plate provides additional support to ensure the smooth operation of the conveyor belt.

Then, motor three is started to drive screw three to rotate, and moving block three and the hole-opening laser nozzle move outward from the axis point of the hole. The moving distance is the same as the radius of the hole to be cut. By flexibly adjusting the position of the hole-opening laser nozzle, the hole-opening requirements at different positions on the brake pad can be met, and the size of the hole can be flexibly adjusted to improve the practicality of the device. By starting the electromagnet to generate a magnetic force with the same polarity as the magnetic block, the magnetic block is driven to rotate by the repulsive force, and the electric push rod six is ​​used to push the stop block to move to block the rotated magnetic block, thereby realizing the rotation and positioning of the magnetic block, and adjusting the position of the rotating disk to achieve cutting at different positions. The number of magnetic blocks can be adjusted according to the actual number of holes to be opened by controlling the electric push rod five to drive the required number of magnetic blocks to move outward, thereby meeting the various hole-opening requirements of the brake pad.

[0023] (3) This scheme starts the motor 1 to drive the screw 1 to rotate, thereby adjusting the position of the outer ring laser nozzle and the inner ring laser nozzle with the cooperation of the moving block 1. The outer ring laser nozzle is used to cut the outer contour of the brake pad, and the inner ring laser nozzle is used to cut the inner contour of the brake pad. After the position adjustment of the outer ring laser nozzle and the inner ring laser nozzle is completed, the electric push rod 3 is started to drive the drive motor to move downward, and the limit block is driven to move downward into the limit groove on the upper surface of the rotating disk. At this time, the electromagnet is turned off and the electric push rod 6 is started to drive the block to move outward and leave the magnetic block. At this time, the drive motor is started to drive the rotating disk and the rotating rod to rotate quickly one circle with the cooperation of the limit block. The outer contour and the inner contour are cut on the brake pad material at the same time by the outer ring laser nozzle and the inner ring laser nozzle, which saves cutting time. All cutting operations can be completed in one positioning, which reduces the cumulative error caused by multiple positioning. BRIEF DESCRIPTION OF THE DRAWINGS

Two support plates 203 are symmetrically fixedly connected on both sides of the inner cavity of the machine tool 1, and two positioning plates 206 are symmetrically fixedly connected to the outer surface of the conveying roller 201.

[0035] Specifically, a conveying motor 207 is fixedly connected to one side of the machine tool 1, and the output shaft end of the conveying motor 207 passes through the machine tool 1 and is fixedly connected to the conveying roller 201. The inner side of the conveying belt 202 abuts against the upper surface of the support plate 203, one side of the positioning plate 206 abuts against one side of the conveying belt 202, and the outer surface of the conveying roller 201 abuts against the outer surface of the support plate 203.

[0036] Furthermore, a bracket 101 is installed on the machine tool 1 for installing and supporting the cutting component to ensure its stability, and the internal components are protected by the outer frame 102 to ensure safe operation. When in use, the operator places the brake pad material to be cut on the conveyor belt 202, and starts the conveying motor 207 to drive the conveyor roller 201 and the conveyor belt 202 to realize automatic transmission of the brake pad material. When the conveyor belt 202 transports the brake pad material from the entrance to the cutting area, the electric push rod 205 is started to drive the positioning plate 206 to move downward to squeeze and fix the brake pad material, thereby ensuring the stability of the finished material during cutting. The support plate 203 provides additional support to ensure the smooth operation of the conveyor belt 202, and the baffle 204 is used to prevent the conveyor belt 202 from deviating from the track during rotation.

[0037] The second implementation method:

[0038] See also Figure 1-5 , including a rotating rod 301 rotatably connected to the middle of the inner cavity of the bracket 101, the outer surface of the rotating rod 301 is fixedly connected to the outer ring adjustment frame 302, the lower end of the rotating rod 301 is fixedly connected to the inner ring adjustment frame 303, the outer ring adjustment frame 302 and the inner ring adjustment frame 303 are rotatably connected to the inner cavity of the screw 1 304, the outer surface of the screw 1 304 is threadedly connected to the moving block 1 3041, the lower surface of the moving block 1 3041 is fixedly connected to the electric push rod 2 306, located in the outer ring adjustment frame 302 The lower end of the electric push rod 2 306 below is fixedly connected to the outer circle laser nozzle 307, the lower end of the electric push rod 2 306 located below the inner circle adjustment frame 303 is fixedly connected to the inner circle laser nozzle 308, the upper end of the rotating rod 301 is fixedly connected to the rotating disk 309, and the upper surface of the bracket 101 is symmetrically fixedly connected to two electric push rods 310, the upper end of the electric push rod 310 is fixedly connected to the driving motor 311, and the output shaft end of the driving motor 311 is fixedly connected to the limiting block 312.

[0039] Specifically, a motor 305 is fixedly connected to one side of the outer ring adjustment frame 302 and the inner ring adjustment frame 303, and the output shaft ends of the two motors 305 respectively penetrate the outer ring adjustment frame 302 and the inner ring adjustment frame 303 and are fixedly connected to the screw 304. There are two moving blocks 3041, and the two moving blocks 3041 move in the inner cavity of the outer ring adjustment frame 302 and the inner ring adjustment frame 303 respectively. A limiting groove 313 is provided on the upper surface of the rotating disk 309, and the limiting block 312 moves in the inner cavity of the limiting groove 313. The limiting block 312 and the limiting groove 313 are rectangular with the same shape.

[0040] Further, the motor 305 is started to drive the screw 304 to rotate, so that the positions of the outer ring laser nozzle 307 and the inner ring laser nozzle 308 are adjusted with the cooperation of the moving block 3041. The outer ring laser nozzle 307 is used to cut the outer contour of the brake pad, and the inner ring laser nozzle 308 is used to cut the inner contour of the brake pad. When the position adjustment of the outer ring laser nozzle 307 and the inner ring laser nozzle 308 is completed, the outer ring laser nozzle 307 is a single-mode laser nozzle. The single-mode laser cutting head has good beam quality and a small focal point, and can achieve high-precision cutting. The cutting edge is smooth and burr-free, which is suitable for outer contour cutting with high requirements on appearance and size, and is suitable for outer contour cutting of brake pads. The inner ring laser nozzle 308 is a three-dimensional laser nozzle, which can cut inner contours, and can adjust the gas flow and pressure according to the specific requirements of the inner contour to optimize the cutting effect, which is suitable for inner contour cutting.

[0041] At this time, the electric push rod 310 is started to drive the driving motor 311 to move downward, and the limit block 312 is driven to move downward into the limit groove 313 on the upper surface of the rotating disk 309. At this time, the electromagnet 412 is closed and the electric push rod 6 413 is started to drive the stop block 414 to move outward and leave the magnetic block 411. At this time, the driving motor 311 is started to drive the rotating disk 309 and the rotating rod 301 to rotate quickly for one circle with the cooperation of the limit block 312. The rotating rod 301 is used to support and drive the outer ring adjustment frame 302 and the inner ring adjustment frame 303. The outer ring laser nozzle 307 and the inner ring laser nozzle 308 are simultaneously The outer contour and the inner contour are cut on the brake pad material to save cutting time. The cutting order of the device is to cut the circular hole first and then cut the inner and outer contours at the same time. This cutting order can ensure that all cutting operations are performed under the same reference with one positioning, reducing the cumulative error caused by multiple positioning, ensuring the accuracy and consistency of the cutting path, and cutting the circular hole first can reduce the overall stress concentration of the material, avoiding deformation of the material due to stress release in the subsequent cutting process. After the circular hole cutting is completed, the stress distribution of the material is more uniform, which is conducive to the precise cutting of the inner and outer contours and reduces edge deformation.

[0042] The outer circle laser nozzle 307 and the inner circle laser nozzle 308 are adjusted in height by the electric push rod 2 306 to achieve cutting at different depths to meet different cutting requirements.

[0043] The third implementation method:

[0044] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6, including an adjustment frame 1 401 fixedly connected to the middle position of the outer surface of the rotating rod 301, the inner cavity of the adjustment frame 1 401 is rotatably connected to a screw 2 402, the outer surface of the screw 2 402 is threadedly connected to a moving block 2 403, the lower surface of the moving block 2 403 is fixedly connected to a motor 2 404, the output shaft end of the motor 2 404 is fixedly connected to an adjustment frame 2 405, the inner cavity of the adjustment frame 2 405 is rotatably connected to a screw 3 406, the outer surface of the screw 3 406 is threadedly connected to a moving block 3 4061, the moving block An electric push rod four 408 is fixedly connected to the lower surface of the third 4061, and a perforated laser nozzle 409 is fixedly connected to the lower end of the electric push rod four 408. A plurality of grooves are evenly opened on the outer surface of the rotating disk 309, and a magnetic block 411 is movably connected in the groove of the rotating disk 309, and an electric push rod five 410 is fixedly connected to one side of the magnetic block 411. An electromagnet 412 is fixedly connected to the upper surface of the bracket 101, and a stop block 414 is abutted against one side of the magnetic block 411, and an electric push rod six 413 is fixedly connected to one side of the stop block 414.

[0045] Specifically, one side of the adjustment frame 1 401 and the adjustment frame 2 405 are fixedly connected with a motor 3 407, and the output shaft ends of the two motors 3 407 respectively penetrate the adjustment frame 1 401 and the adjustment frame 2 405 and are fixedly connected with the screw 2 402 and the screw 3 406, the moving block 2 403 moves in the inner cavity of the adjustment frame 1 401, and the moving block 3 4061 moves in the inner cavity of the adjustment frame 2 405, the end of the electric push rod 5 410 away from the magnetic block 411 is fixedly connected to the inner wall of the groove of the rotating disk 309, and the end of the electric push rod 6 413 away from the stop block 414 is fixedly connected to the inner wall of the outer frame 103, the polarity of the electromagnet 412 and the magnetic block 411 is the same and after the electromagnet 412 is energized, the magnetic block 411 will be subjected to a repulsive force.

[0046] Further, the motor three 407 is started to drive the screw two 402 to rotate, the position of the moving block two 403 is adjusted, and the hole-opening laser nozzle 409 is driven to move to the axis point of the hole on the brake pad that needs to be cut, and then the motor three 407 is started to drive the screw three 406 to rotate, and the moving block three 4061 and the hole-opening laser nozzle 409 move outward from the axis point of the hole. The moving distance is the same as the radius of the hole to be cut. By flexibly adjusting the position of the hole-opening laser nozzle 409, the opening of holes at different positions on the brake pad can be achieved. The hole requirement can be met, and the size of the hole can be flexibly adjusted to improve the practicability of the device. Then, the motor 2 404 is started to drive the hole-opening laser nozzle 409 to rotate according to the specified radius to achieve rapid hole opening, and the electric push rod 5 410 is used to adjust the height of the hole-opening laser nozzle 409 to achieve cutting at different depths. The hole-opening laser nozzle 409 is a multi-mode laser nozzle or a high-precision laser cutting head, which is suitable for cutting the center hole of the brake pad, and can ensure the roundness and dimensional accuracy of the center hole, thereby ensuring the perfect fit between the brake pad and the brake caliper.

[0047] When it is necessary to rotate and adjust the angle of the hole-opening laser nozzle 409 to cut multiple holes, the electromagnet 412 is started to generate a magnetic force with the same polarity as the magnet 411, and the magnet 411 is pushed to rotate by the repulsive force, and the stopper 414 is pushed to move by the electric push rod 6 413 to block the rotated magnet 411, so as to realize the rotation and positioning of the magnet 411, and to adjust the position of the rotating disk 309 to realize cutting at different positions. After the magnet 411 is rotated and adjusted, it is blocked and positioned by the stopper 414, and at the same time, the repulsive force is used to ensure that it will not reverse, thereby ensuring the stability of its rotation adjustment. The number of magnets 411 can be adjusted according to the actual number of holes required, and the required number of magnets 411 can be driven to move outward by controlling the electric push rod 5 410 so that they can contact the stopper 414, thereby meeting the various hole opening requirements of the brake pad.

[0048] Working principle: During the use of the device, the operator places the brake pad material to be cut on the conveyor belt 202, starts the conveying motor 207 to drive the conveyor roller 201 and the conveyor belt 202 to realize the automatic transmission of the brake pad material. When the conveyor belt 202 transports the brake pad material from the entrance to the cutting area, the electric push rod 1 205 is started to drive the positioning plate 206 to move downward to squeeze and fix the brake pad material to ensure the stability of the finished product material during cutting. The support plate 203 provides additional support to ensure the smooth operation of the conveyor belt 202. The baffle 204 is used to prevent the conveyor belt 202 from deviating from the track during rotation. After the brake pad material is fixed, the motor 3 407 is started to drive the screw 2 402 to rotate and adjust the position of the moving block 2 403. The motor 407 is then started to drive the hole-opening laser nozzle 409 to move to the axis point of the hole on the brake pad that needs to be cut, and then the motor 407 is started to drive the screw 406 to rotate, driving the moving block 4061 and the hole-opening laser nozzle 409 to move outward from the axis point of the hole, and the moving distance is the same as the radius of the hole to be cut. By flexibly adjusting the position of the hole-opening laser nozzle 409, the hole-opening requirements at different positions on the brake pad can be met, and the size of the hole can be flexibly adjusted. Then, the motor 404 is started to drive the hole-opening laser nozzle 409 to rotate according to the specified radius to achieve rapid hole opening, and the electric push rod 5 410 is used to adjust the height of the hole-opening laser nozzle 409 to achieve cutting of different depths. When it is necessary to rotate and adjust the hole-opening laser nozzle 40 9, when cutting multiple holes at an angle of 9, the electromagnet 412 is started to generate a magnetic force with the same polarity as the magnetic block 411, and the magnetic block 411 is pushed to rotate by the repulsive force, and the electric push rod 6 413 is used to push the stopper 414 to move to block the rotated magnetic block 411, so as to realize the rotation and positioning of the magnetic block 411, and to adjust the position of the rotating disk 309 to realize cutting at different positions. The number of magnetic blocks 411 can be adjusted according to the actual number of holes to be opened, and the electric push rod 5 410 is controlled to drive the required number of magnetic blocks 411 to move outward so that they can contact with the stopper 414, so as to meet the various hole opening requirements of the brake pad. When the hole opening is completed, the motor 1 305 is started to drive the screw 1 304 to rotate, so as to move the block 1 304. 1, the positions of the outer ring laser nozzle 307 and the inner ring laser nozzle 308 are adjusted. The outer ring laser nozzle 307 is used to cut the outer contour of the brake pad, and the inner ring laser nozzle 308 is used to cut the inner contour of the brake pad. When the position adjustment of the outer ring laser nozzle 307 and the inner ring laser nozzle 308 is completed, the electric push rod three 310 is started to drive the drive motor 311 to move downward, and drive the limit block 312 to move downward into the limit groove 313 on the upper surface of the rotating disk 309. At this time, the electromagnet 412 is turned off and the electric push rod six 413 is started to drive the stop block 414 to move outward and leave the magnetic block 411. At this time, the drive motor 311 is started to drive the rotating disk 309 and the rotating rod 301 to rotate quickly for one circle with the cooperation of the limit block 312.The outer ring laser nozzle 307 and the inner ring laser nozzle 308 simultaneously cut the outer contour and the inner contour on the brake pad material. The outer ring laser nozzle 307 and the inner ring laser nozzle 308 adjust the height through the electric push rod 2 306 to achieve cutting at different depths.
