[0002] The materials of large-diameter brake discs include gray cast iron, ductile iron, carbon steel, etc. Gray cast iron is widely used. The surface treatment of large-diameter gray cast iron brake discs usually uses abrasive tools for grinding and polishing, and then deep processing is performed to form a finished product after grinding and polishing;

[0003] The brake disc leveling fine-tuning process can ensure uniform contact between the brake disc and the brake pad, improve braking stability, and reduce vibration and jitter during braking. By fine-tuning the levelness of the brake disc, the friction force distribution between the brake disc and the brake pad can be optimized, the braking effect can be improved, and the braking distance can be shortened. The leveling fine-tuning can also reduce the uneven wear of the brake disc and brake pad, extend the service life of the brake system, and reduce the frequency of maintenance and replacement.

[0004] In the process of fine-tuning the horizontality of a large-diameter brake disc, the corresponding grinding process also changes due to the large diameter of the brake disc. Referring to the contents disclosed in publication number CN118219082A, the grinding spacing is adjusted according to the size of the brake disc and a dust removal function is provided at the same time, such as the contents disclosed in publication number CN118528161A;

[0043] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] Embodiment 1: In the surface treatment process of a large-diameter brake disc, it is difficult to perform adaptive grinding adjustment and feeding according to the horizontality of the brake disc. For this purpose, the following technical solution is proposed:

[0045] Reference Figure 1 - Fig.10 As shown, the large-diameter brake disc surface treatment device with a horizontality fine-tuning function in this embodiment includes a main frame 1 and a sub-frame 2, a control panel is installed outside the sub-frame 2, and a main transfer mechanism 4 is installed on the sub-frame 2;

[0046] The main transfer mechanism 4 includes a pair of main slide rails 401 and a main slide 402. The main slide 402 is provided with a leveling mechanism 5. The leveling mechanism includes a mounting plate 501 rotatably arranged on the main slide 402. A side mounting plate 503 is mounted on one side of the mounting plate 501. A second cylinder 502 is mounted on the side of the upper surface of the mounting plate 501 away from the side mounting plate 503. The output end of the second cylinder 502 is provided with a tool for grinding the brake disc.

[0047] The grinding assembly 6 is rotatably arranged on the opposite side mounting plate 503, and the grinding assembly 6 includes a grinding wheel 602 and a driven rotating wheel 603 arranged on the same axis, the driven rotating wheel 603 is rotatably connected to the driving rotating wheel 601, and a disc seat 11 is rotatably installed on the middle part of the auxiliary frame 2 near the main frame 1, and the tangent line of the grinding wheel 602 is arranged parallel to the upper surface of the disc seat 11;

[0048] Reference Figure 5 As shown, the auxiliary frame 2 is provided with auxiliary transfer mechanisms 7 on both sides of the corresponding disc seat 11, and the auxiliary transfer mechanisms 7 include a magnetic chuck 706 arranged on a pair of auxiliary slide rails 701, and a clamping seat 704 for clamping the magnetic chuck 706 is slidably mounted on the auxiliary slide rails 701, and a feeding assembly 8 for continuous feeding of the brake disc is installed below the magnetic chuck 706;

[0049] Reference Figure 7 As shown, a swing wheel seat 505 is installed on the outer side of the side mounting plate 503, and the driving wheel 601 and the grinding wheel 602 are both rotatably mounted on the swing wheel seat 505. A connecting rod 504 fixedly connected to the output end of the second cylinder 502 is installed on the inner side of the upper end of the swing wheel seat 505. A second motor 506 for driving the driving wheel 601 to rotate is installed on the side mounting plate 503. When the second motor 506 is started, the driving wheel 601 drives the grinding wheel 602 to rotate through the driven wheel 603. When the second cylinder 502 is started, the swing wheel seat 505 rotates with the mounting hole of the side mounting plate 503 as the axis and drives the driving wheel 601 and the grinding wheel 602 to deflect.

[0050] Reference Figure 7 As shown, a cleaning disc 9 is installed on the inner side of the active rotating wheel 601 close to the side mounting plate 503, and the cleaning disc 9 is connected to the pneumatic suction source. A suction hole 10 opposite to the outer ring side of the grinding wheel 602 is opened on the outer ring side of the cleaning disc 9. The suction holes 10 on the cleaning disc 9 provide suction for the grinding chips contaminated on the surface of the grinding wheel 602 during the grinding process, thereby avoiding the situation where the abrasive damages the brake disc during the grinding process of the grinding wheel 602.

[0051] The control panel is built with a control system, which includes a parameter acquisition unit, a data analysis unit, an execution control unit, an image analysis unit and a processor that are communicatively connected;

[0052] The parameter acquisition unit is used to obtain the longitudinal and transverse feed values ​​ZH and the deflection position values ​​PZ during the grinding of the brake disc, and calculate the longitudinal and transverse feed values ​​ZH and the deflection position values ​​PZ through the formula to obtain the feed deflection coefficient JPx, and then send the feed deflection coefficient to the feed data analysis unit and the image analysis unit to analyze whether the grinding wheel 602 is operating normally during the grinding of the brake disc. After receiving the deflection coefficient, the data analysis unit specifically analyzes the brake disc grinding process as follows:

[0053] S1: Construct the calculation formula of feed deflection coefficient Wherein a, b, c are preset proportional coefficients, and k is a preset fault tolerance factor coefficient, and a>b>c>k>0;

[0054] S2: Compare the feed deflection coefficient with the feed deflection value preset in the processor, if the feed deflection coefficient is greater than the feed deflection value, generate a positive adjustment signal, if the feed deflection coefficient is less than or equal to the feed deflection value, generate a negative adjustment signal, and send the positive adjustment signal and the negative adjustment signal to the execution control unit;

[0055] S3: The execution control unit is used to adjust the position of the grinding wheel 602 and the disc seat 11. The execution control unit receives the positive adjustment signal and the reverse adjustment signal to respectively start the motor 1 403, the cylinder 1 404, the cylinder 3 703 and the motor 2 506. The control process is as follows:

[0056] When the positive adjustment signal is received, the motor 1 403 is started, driving the main slide 402 to move, and the main slide 402 drives the grinding wheel 602 at the grinding end to produce horizontal displacement, so that the grinding wheel 602 and the brake disc on the disc seat 11 form a horizontal correction lack feed; at the same time, the cylinder 1 404 is started, driving the grinding wheel 602 at the grinding end to produce longitudinal displacement, so that the grinding wheel 602 and the brake disc on the disc seat 11 form a longitudinal correction lack feed;

[0057] When a reverse adjustment signal is received, similarly, in contrast to the above-mentioned execution control process, the grinding wheel 602 and the brake disc on the disc seat 11 form a lateral correction and compensation feed, and the grinding wheel 602 and the brake disc on the disc seat 11 form a longitudinal correction and compensation feed;

[0058] After the correction of the lack of feed and the correction of the compensation feed are completed, the motor 2 506 is started to drive the active wheel 601 to rotate, and the active wheel 601 drives the driven wheel 603 coaxially arranged with the grinding wheel 602 to rotate, so that the grinding wheel 602 is attached to the surface of the brake disc to complete the grinding process;

[0059] It is important to note that, refer to Figure 4As shown, the adjustment of grinding level can be briefly summarized as follows: the grinding contact position of the grinding tool wheel 602 and the brake disc surface changes as it moves from the edge side to the proximal side, that is, from the edge side to the proximal side, the two sides of the cross section of the brake disc after grinding are in the shape of a frustum waistline structure, and at the same time meet the level adjustment processing requirements;

[0060] After receiving the deflection coefficient, the image analysis unit performs image analysis, generates a level deviation signal based on the analysis result, and sends it to the maintenance personnel's mobile terminal for active maintenance. The image analysis process of the image analysis unit is as follows:

[0061] A curve graph in the first quadrant is drawn with the running time t of the grinding equipment as the abscissa value and the absolute value D of the difference between the thickness value of the edge side and the thickness value of the proximal side of the brake disc after grinding as the ordinate value;

[0062] When the absolute value of the edge side thickness value - the near-axis side thickness value is constant, it means that the current level meets the standard requirements; on the contrary, if the absolute value of the edge side thickness value - the near-axis side thickness value fluctuates, it means that the current level has deviations;

[0063] Image analysis: Specifically, the smooth curve at each time point t is drawn within the time Δt and compared with the preset standard curve, the longitudinal coordinate value of the time point t is obtained and marked as the beating data TD, all the beating data are summed up and the average beating data PT is calculated, and the beating discrete value is obtained by the formula calculated by the data analysis unit Where n is a positive integer greater than zero, and then the runout discrete value TDz is compared and analyzed with the preset runout discrete threshold TDy. If the runout discrete value TDz is greater than or equal to the preset runout discrete threshold TDy, it indicates that the current grinding equipment is operating abnormally; otherwise, it indicates that the operation is normal.

[0064] Basic principle: Based on the grinding process of the brake disc, by obtaining the values ​​of the longitudinal and transverse feed and deflection position during the grinding of the brake disc, and then combining the jump change data of the edge side thickness value and the near-axis side thickness value, it is jointly judged whether the current grinding equipment is in normal operation. In practice, it is manifested as the adaptive adjustment of the horizontality during the grinding process of large-diameter brake discs, thereby making guiding early warning and control actions for the entire large-diameter brake disc surface treatment process, improving the level of intelligent working condition monitoring and control, and improving the grinding processing efficiency.
