Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of railway passenger car brake pad grinding, in particular to an automatic grinding device for railway passenger car brake pads. Background Art
[0002] Railway passenger car brake pads are brake materials used on existing passenger cars. During assembly, brake pads need to be installed in pairs on brake pad holders for use. For the driving safety of trains, the "Railway Passenger Car Section Repair Regulations" TG / CL208-2022 stipulates: "The thickness of the brake pad shall not be less than 20mm, the difference in the thickness of the brake pads on both sides of the same unit brake cylinder shall not exceed 5mm, and the difference in the thickness of the upper and lower brake pads on the same side shall not exceed 1mm. When the brake pads on the same brake pad holder are replaced, they shall be updated at the same time."
[0003] Therefore, in actual application, the old brake pads unloaded from the section-repaired passenger car cannot meet the above-mentioned loading conditions, so two new brake pads need to be installed on the same brake pad. This has high maintenance costs, the old brake pads cannot be fully utilized, and there is a serious waste of materials.
[0004] To this end, we have designed an automatic grinding device for the replaced pairs of old brake pads. By designing a brake pad locking plate that corresponds to the bulge at the bottom of the brake pad, the brake pad is fixed with the locking plate. The thickness difference is measured by an industrial camera and a ranging sensor, so that the old brake pad can be automatically ground. When the thickness difference is ground to within the specified range, it can be installed and used again, which improves the utilization rate of the brake pad and avoids material waste.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example
[0021] See also Figure 1-4 The present embodiment provides an automatic grinding device for brake pads of railway passenger cars, including a base 1, on which a locking plate assembly for clamping the brake pad is arranged. Specifically, the locking plate assembly includes a fixed locking plate 2 arranged on the base 1, and a movable locking plate 3 is movably arranged on one side of the fixed locking plate 2. The fixed locking plate 2 and the movable locking plate 3 are correspondingly provided with a clamping groove 4 for clamping the brake pad. As a conventional operation familiar to those skilled in the art, Figure 1 As shown, a guide groove 7 is provided on the base 1, a first slider 6 is slidably arranged in the guide groove 7, a first lead screw 8 is rotatably arranged in the guide groove 7 to penetrate the first slider 6 and is threadedly connected to the first slider 6, a handle is provided at the end of the first lead screw 8, and a movable locking plate 3 is provided on the first slider 6. Figure 2-3 As shown, the shape of the slot 4 corresponds to the protrusion at the bottom of the gate piece. Since the protrusion at the bottom of the gate piece is trapezoidal, the slot 4 on the fixed lock plate 2 and the movable lock plate 3 is also trapezoidal after docking, which just clamps and fixes the protrusion at the bottom of the gate piece.
[0022] A grinding assembly is movably arranged above the locking plate assembly, such as Figure 1As shown, a vertical rail 9 is provided on one side of the base 1, a horizontal rail 13 that can move up and down is provided on the vertical rail 9, and a support plate 18 that can move horizontally is provided on the horizontal rail 13. Specifically, as a conventional structure familiar to those skilled in the art, a second slider 10 is slidably provided on the vertical rail 9, a second lead screw 11 for driving the second slider 10 to reciprocate is rotatably provided in the vertical rail 9, a first motor 12 for driving the second lead screw 11 to rotate is provided on the vertical rail 9, and the horizontal rail 13 is fixedly connected to the second slider 10. At the same time, as a conventional structure familiar to those skilled in the art, in order to realize the movement of the support plate 18, a third slider 14 is slidably provided in the horizontal rail 13, a third lead screw 15 for driving the third slider 14 to move is rotatably provided in the horizontal rail 13, a second motor 16 for driving the third lead screw 15 to rotate is provided on one side of the horizontal rail 13, an opening 17 is provided on one side of the horizontal rail 13, the support plate 18 passes through the opening 17 and is connected to the third slider 14, and the third slider 14 can drive the support plate 18 to move along the opening 17. The grinding assembly is arranged on the support plate 18. Specifically, the grinding assembly includes a grinding motor 21 fixedly arranged at the lower end of the support plate 18. A grinding plate 20 is arranged at the output end of the grinding motor 21. The grinding plate 20 is correspondingly arranged above the fixed locking plate 2 and the movable locking plate 3.
[0023] In order to measure the thickness of the gate pad and determine the position of the gate pad, side panels 19 fixed on the support plate 18 are arranged on both sides of the grinding pad 20, and the lower ends of the side panels 19 on both sides are respectively provided with ranging components and industrial cameras 22. The ranging components and the industrial cameras 22 are both directly obtained by purchase and will not be described in detail. In the present application, the ranging component is preferably a ranging sensor 23.
[0024] It should be noted that in actual applications, a main controller 5 is also required to realize the regulation between the industrial camera 22, the distance sensor 23, the first motor 12 and the second motor 16. By placing the gate pieces in pairs on the fixed lock plate 2, the convex side of the bottom of the gate piece is clamped into the slot 4 of the fixed lock plate 2, and then the movable lock plate 3 is close to the fixed lock plate 2, so that the slot 4 of the movable lock plate 3 clamps the gate piece, thereby fixing the gate piece. By inputting the corresponding grinding thickness parameters on the main controller 5, the main controller 5 controls the movement of the first motor 12 and the second motor 16, firstly drives the industrial camera 22 and the distance sensor 23 to move horizontally, measures the position and thickness of the gate piece, and after obtaining the corresponding data, drives the grinding piece 20 to descend to the grinding position by the support plate 18, and drives the grinding piece 20 to move by the grinding piece motor 21, thereby grinding the gate piece. After grinding, the distance sensor 23 measures the thickness again, and the gate piece can be removed after reaching the standard.
[0025] Among them, the main controller 5 can be obtained through customized purchase and is a general device that can be directly obtained by technical personnel in this field. The internal control program can be implemented through customized programming, and this application will not go into details.
