In this embodiment, the rotary servo motor at the bottom of the positioning clamps 9 can realize linkage and precise positioning of the position measurement and grinding of each brake pad set on the positioning clamps 9.

[0034] In this embodiment, the slide 8 can slide forward and backward on the slide rail 7. The slide 8 is provided with a driving screw 11, which is connected to a driving motor 15. The driving motor 15 and the driving screw 11 drive the slide 8 to slide on the slide rail 7. Thus, the slide 8 is controlled to achieve accurate positioning of the three positions of manual loading and unloading position, measurement position and grinding position.

[0035] The visual measuring device 4 includes a visual six-axis robot 17 and a 3D visual camera 18. The visual six-axis robot is fixed on the fixed frame 3, and the 3D visual camera 18 is fixed on the head end of the visual six-axis robot 17. The position of the 3D visual camera can be adjusted under the drive of the visual six-axis robot.

[0036] The 3D vision camera is linked with the rotary servo motor to automatically measure and record all dimensions of the gate pad. The gate pad is transmitted to the visual measuring device 4 through the slide rail 7 and the slide table 8. The overall dimensions of the gate pad are measured by the 3D vision camera to automatically collect all data and calculate whether the thickness of each gate pad meets the qualified standard. The locations where the measurement data is unqualified are marked and transmitted to the automatic grinding device 5.

[0037] The grinding device 5 is used to grind the brake pads to the required size. The slide 8 transfers the brake pads on the positioning clamp 9 to the grinding station. According to the size measured by the 3D vision camera, the position and amount of grinding required can be accurately located.

[0038] The grinding device 5 includes a grinding six-axis robot 19 and a grinding head 20. The grinding six-axis robot 19 is fixed on the cabinet 1, and the grinding head 20 is fixed on the head end of the grinding six-axis robot 19.

At the same time, the visual measuring device 4 links the rotating servo motor to measure the surroundings of the gate piece. After the measurement of the two gate pieces is completed, a test data model is formed, the measurement standard is compared, the position points that exceed the requirements are automatically marked, and the data is transmitted to the grinding device 5. If the measured gate piece thickness is lower than the standard value, the gate piece is returned to the manual side, and the display lifts the gate piece to be scrapped;

[0044] like Figure 6As shown, (3) after the gate 14 slides to the grinding station, the grinding device 5 starts, carrying the grinding head and the dust removal equipment to start working, and grinds the position given by the visual measuring device 4. According to the required grinding feed amount, the grinding device 5 grinds to the required size (grinding amount). After all the marked position points are polished as required, the grinding device 5 returns to the origin and the dust removal equipment stops;

[0045] (4) After the gate piece 14 is polished, it slides to the visual measuring device 4 station to re-measure the polished gate piece. When the size meets the maintenance requirements, it slides to the manual side, the manual work is completed, and the gate piece measurement data after maintenance is recorded; if the measurement is unqualified, the unqualified position point is marked again and action (3) is repeated until the measurement is qualified and it returns to the manual side;

[0046] (5) After the operation is completed, the brake pads are manually unloaded and replaced with the next set of brake pads.

[0047] The utility model has the functions of automatic measurement and grinding, and can automatically measure the brake pad and give the position point and grinding amount to be ground. The grinding device 5 automatically grinds the specified position point according to the measured data and automatically feeds the grinding amount. The polished brake pad will return to the measurement area for another measurement to ensure that it is polished in place and meets the maintenance standards, thus realizing the closed-loop management of brake pad maintenance.

[0048] The utility model can replace the current traditional manual operation mode, replace manual measurement and manual grinding, and solve the problems of large maintenance workload, low maintenance efficiency, and manual recording of maintenance data. It adopts fully automatic measurement mode and fully automatic grinding technology. Manual labor only needs to load and unload materials to meet the maintenance requirements. Not only is the maintenance efficiency high, the maintenance data is automatically recorded, and the maintenance quality and quality are effectively improved.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
