Description

Technical Field

[0001] The present invention relates to the technical field of rail transit wheel-mounted brake discs, and particularly relates to a device and method for measuring the deformation of a wheel-mounted brake disc. Background Art

[0002] The disc body of the wheel-mounted brake disc of a rail transit vehicle is fixed to the wheel through accessories such as fasteners. When the wheel wears to the limit and the disc body of the wheel-mounted brake disc is disassembled from the wheel, due to the long-term exposure of the disc body to braking heat load, the disc body of the wheel-mounted brake disc will undergo plastic deformation, resulting in dish-shaped plastic deformation and twisted wave plastic deformation, which causes the flatness of the disc body to not meet the requirements for reinstallation, resulting in the scrapping of the old disc body.

[0003] In the prior art, during the operation of rail transit vehicles, electric braking is mainly used, and air braking is supplemented only when the electric braking is insufficient. Therefore, the wear of the disc body is generally less. When the wheel reaches the limit, there is still a relatively large thickness of the disc body of the wheel-mounted brake disc that can be worn. However, after the old disc body is disassembled from the wheel, the flatness of the installation surface of the disc body sometimes cannot meet the reinstallation requirements, resulting in a large number of disc bodies of wheel-mounted brake discs being scrapped in advance due to the wheel reaching the limit, which causes serious equipment waste.

[0052] Embodiment 1

[0053] Please refer to Figure 1 and Figure 2As shown in the figure, in an embodiment of the present invention, a wheel-mounted brake disc deformation measurement device is provided. The wheel-mounted brake disc includes a wheel and two disc bodies 4 respectively arranged on both sides of the wheel. The wheel-mounted brake disc deformation measurement device includes: a liftable rotary test bench 1, and a disc clamping mechanism 1042 is arranged on the rotary test bench 1; a measurement illumination system 2, including an illumination module 202 arranged along the circumference of the rotary test bench 1 and an optical test module 201, and the optical test module 201 has a measurement field of view for scanning the rotary test bench 1; and a control system 3, and the control system 3 is electrically connected to the rotary test bench 1 and the measurement illumination system 2.

[0054] Overall, when the wheel-mounted brake disc deformation measurement device is in use, the disc clamping mechanism 1042 can quickly clamp the disc body 4 to be tested on the rotary test bench 1. The rotary test bench 1 can adjust the disc body 4 to the target height and drive the disc body 4 to rotate, facilitating the disc body 4 to be better placed under the light of the illumination module 202 to remove the shadow on the disc body 4. And during the rotation of the disc body 4, the optical test module 201 can accurately collect the actual deformation data of each rib and rib 403 on the disc body 4 and upload the actual deformation data to the control system 3. The control system 3 can calculate the wear data of the disc body 4 and can efficiently compare the actual wear data of the disc body 4 with the standard value of the disc body 4 to determine whether the disc body 4 meets the reuse standard. When the disc body 4 meets the reuse standard, the disc body 4 is subjected to an orthopedic process and then reused for loading, thus greatly reducing the waste of the disc body 4 and improving the utilization rate of the disc body 4.

[0055] In an embodiment of the present invention, the rotary test bench 1 includes a base 101, a lifting and rotating mechanism 103 arranged on the base 101, and a test platform 104 arranged on the lifting and rotating mechanism 103, and the disc clamping mechanism 1042 is arranged on the test platform 104.

[0056] The disc clamping mechanism 1042 can fix the disc body 4 to be tested on the test platform 104, and then the lifting and rotating mechanism 103 can drive the test platform 104 to lift and can also drive the test platform 104 to rotate.

[0057] The lifting and rotating mechanism 103 can lift the test platform 104 to the target height position, so that the disc body 4 is completely irradiated by the illumination module 202 to remove the shadow on the disc body 4, thereby improving the data acquisition accuracy of the optical test module 201.

[0058] Moreover, the lifting and rotating mechanism 103 drives the disc body 4 to rotate, so that the optical test module 201 can scan the disc body 4 360°, in order to better collect the wear data of each rib and rib 403 on the disc body 4.

[0059] Specifically, the base 101 includes a supporting flat plate 1012, and a relatively horizontal mounting end face is formed through the supporting flat plate 1012 to mount the lifting and rotating mechanism 103.

[0060] In an embodiment of the present invention, the base 101 is provided with a horizontal adjustment structure, and the horizontal adjustment structure includes a plurality of height adjustment members 1011 adjustably arranged on the base 101.

[0061] By using the plurality of height adjustment members 1011, the levelness of the base 101 can be adjusted, thereby avoiding the inclination of the test platform 104 and affecting the scanning accuracy of the optical test module 201.

[0062] Specifically, the height adjustment member 1011 includes a cylindrical leg adjustably arranged on the base 101, and a plurality of cylindrical legs can be respectively arranged at the four corners of the base 101 to support the base 101.

[0063] Designers can determine the adjustment structure between the cylindrical leg and the base 101 according to the usage needs. For example, a threaded connection is adopted between the cylindrical leg and the base 101 to form an adjustable structure, which is not specifically limited herein.

[0064] In an embodiment of the present invention, the rotary test bench 1 further includes a guard plate 102. Along the circumferential direction of the test platform 104, the guard plate 102 is annularly arranged on the base 101, and the test platform 104 is located in the space clamped by the guard plate 102.

[0065] Specifically, the guard plate 102 is arranged along the circumferential direction of the test platform 104 to form a cylindrical shape. By arranging the test platform 104 inside the guard plate 102, a relatively enclosed measurement space is formed. The lighting module 202 and the optical test module 201 are installed on the guard plate 102 or in the space clamped by the guard plate 102, thereby avoiding the interference of the measurement lighting system 2 by the external environment and achieving a more stable lighting and scanning effect.

[0066] In an embodiment of the present invention, as Figure 5 shown in the embodiment, the lifting and rotating mechanism 103 includes a vertically movable main shaft 1032, a tray 1033 arranged on the main shaft 1032, a thrust bearing 1034 arranged on the tray 1033, a disk rotating gear 1043 rotatably arranged on the thrust bearing 1034, and a rotation driving motor 105. The rotation driving motor 105 is connected to the main shaft 1032 through a connection bracket 1053. The disk rotating gear 1043 is connected to the test platform 104 and is coaxially arranged. A motor rotating gear 1052 is arranged on the rotating shaft 1051 of the rotation driving motor 105, and the motor rotating gear 1052 is meshed with the disk rotating gear 1043 in a transmissible manner.

[0067] Specifically, the test platform 104 has an opposite platform upper surface 1041 and a platform lower surface. The platform upper surface 1041 is perpendicular to the main shaft 1032. The platform lower surface is connected to the disk rotation gear 1043, and the disk rotation gear 1043 is connected to the inner diameter of the thrust bearing 1034. The liftable main shaft 1032 can push the tray 1033 and the thrust bearing 1034 to perform a lifting motion, thereby driving the test platform 104 to lift.

[0068] Moreover, the rotation drive motor 105 is connected to the main shaft 1032 through the connection bracket 1053, so that the rotation drive motor 105 can lift and lower synchronously with the test platform 104. The rotation drive motor 105 drives the motor rotation gear 1052 to rotate through the rotation shaft 1051. Since the motor rotation gear 1052 is meshed with the disk rotation gear 1043 in a transmissible manner, the test platform 104 can be driven to perform a circular motion. Through the cooperation of the main shaft 1032 and the rotation shaft 1051, the test platform 104 can be driven to perform a lifting motion and also a rotational motion.

[0069] In a specific embodiment, the main shaft 1032 is the piston rod of a hydraulic cylinder, and the lifting motion of the piston rod is realized through hydraulic pressure.

[0070] In another specific embodiment, the main shaft 1032 is the piston rod of a pneumatic cylinder, and the lifting motion of the piston rod is realized through air pressure.

[0071] The designer can also set the lifting and rotating mechanism 103 to other structures with the same function according to the usage requirements, which are not limited herein.

[0072] In the embodiment of the present invention, the lighting module 202 includes a lighting light strip arranged in a circumferential ring along the test platform 104, and the lighting light strip can illuminate the test platform 104.

[0073] By arranging the lighting light strip in a ring shape, the light can be focused on the test platform 104, which is beneficial to improving the recognition accuracy of the optical test module 201.

[0074] The designer can determine the specific structure of the lighting light strip according to the lighting needs. For example, the lighting light strip can be set as an LED lamp, which is not specifically limited herein.

[0075] In a specific embodiment, the optical test module 201 is an industrial camera, and the industrial camera has a measurement field of view for scanning the test platform 104. By using the industrial camera, the disk body 4 placed on the test platform 104 can be photographed to collect the actual deformation data of the disk body 4.

[0076] In another specific embodiment, the optical test module 201 is a laser profiler, and the laser profiler has a measurement field of view for scanning the test platform 104. By using the laser profiler, the disk body 4 placed on the test platform 104 can be photographed to collect the actual deformation data of the disk body 4.

[0077] In other specific embodiments, the designer can also adjust the specific structure of the optical test module 201 according to the actual scanning requirements of the disk body, which is not specifically limited herein.

[0078] In the embodiment of the present invention, the disk body clamping mechanism 1042 includes an annular clamping tooling arranged on the test platform 104, and the annular clamping tooling has an inner support structure and / or an outer support structure, and the inner support structure and / or the outer support structure are used for clamping the disk body 4.

[0079] In a specific embodiment, the annular clamping tooling includes an outer support structure, and the outer support structure can be used to center and clamp the outer edge of the disk body 4, which is convenient for fixing the disk body 4 at the target position on the test platform 104, so that the center of the disk body 4 is collinear with the rotation axis of the test platform 104.

[0080] In another specific embodiment, the annular clamping tooling includes an inner support structure, and the inner support structure can be used to center and clamp the inner edge of the disk body 4, which is convenient for fixing the disk body 4 at the target position on the test platform 104, so that the center of the disk body 4 is collinear with the rotation axis of the test platform 104.

[0081] In still another specific embodiment, the annular clamping tooling includes an outer support structure and an inner support structure. By cooperating with the outer support structure and the inner support structure, the outer edge and the inner edge of the disk body 4 can be centered and clamped, which has better clamping accuracy and is convenient for fixing the disk body 4 at the target position on the test platform 104, so that the center of the disk body 4 is collinear with the rotation axis of the test platform 104.

[0082] In the embodiment of the present invention, the disk body clamping mechanism 1042 further includes an electromagnetic adsorption module arranged on the test platform 104, and the electromagnetic adsorption module has a power-on state for locking the disk body 4 and a power-off state for releasing the disk body 4.

[0083] By arranging the electromagnetic adsorption module on the test platform 104, the clamping stability of the disk body 4 can be further improved, and the problem of displacement of the disk body 4 during rotation can be avoided. Specifically, the electromagnetic adsorption module includes at least one electromagnet arranged on the test platform 104.

[0084] In the embodiment of the present invention, the control system 3 includes a bracket 301 connected to the rotary test bench 1 and a computer module 302 arranged on the bracket 301, and the computer module 302 is electrically connected to the rotary test bench 1 and the measurement illumination system.

[0085] Specifically, the support 301 is provided with a channel for the circuit to pass through. The computer module 302 is electrically connected to the lifting and rotating mechanism 103 and the measurement and lighting system 2 through the circuit, so as to control the lifting process and the rotating process of the rotating test bench 1, as well as the lighting process and the scanning process of the measurement and lighting system 2.

[0086] Moreover, through the computer module 302, it is also possible to store the wear data of the disk body 4 collected by scanning through the optical test module 201, as well as the standard values of the disk body 4. By pre-inputting the set values that the disk body 4 meets the standards in the computer module 302, thus by comparing the wear data of the disk body 4 collected by scanning through the optical test module 201 and the standard values of the disk body 4, the computer module 302 can automatically determine whether the disk body 4 meets the reuse standards, thereby significantly improving the reuse detection efficiency of the disk body 4.

[0087] Embodiment 2

[0088] The embodiment of the present invention also provides a method for measuring the deformation of a wheel-mounted brake disk, including the following steps:

[0089] Step 1000: Based on the rotating test bench 1, establish a reference plane.

[0090] Step 2000: Fix the disk body 4 to be tested through the disk body clamping mechanism 1042 on the rotating test bench 1, and drive the disk body 4 to rotate by using the rotating test bench 1.

[0091] Step 3000: During the rotation of the disk body 4, collect the actual deformation data of the disk body 4 through the measurement and lighting system 2, and upload it to the control system 3.

[0092] Step 4000: Based on the actual deformation data, use the control system 3 to calculate the wear data of the disk body 4; wherein, the wear data at least includes the total wear value H of the disk body 4 a 、the dish-shaped plastic deformation value H of the disk body 4 b 、and the twisted wave plastic deformation value H of the disk body 4 c .

[0093] Step 5000: Compare the wear data with the standard values of the disk body 4 to determine whether the disk body 4 meets the reuse standards.

[0094] By using the measurement and lighting system 2 to collect the actual deformation data of the disk body 4. Through the control system 3, the wear data of the disk body 4 can be calculated, and then the actual wear data of the disk body 4 is compared with the standard values of the disk body 4, so as to determine whether the disk body 4 meets the reuse standards. When the disk body 4 meets the reuse standards, the disk body 4 is reused, thereby greatly reducing the waste of the disk body 4 and improving the utilization rate of the disk body 4.

[0095] In an embodiment of the present invention, the specific steps for collecting the actual deformation data of the disk body 4 by the measurement illumination system 2 are as follows:

[0096] Step 3001: Use the illumination module 202 to focus the light on the disk body 4 so that the disk body 4 is completely irradiated by the light without shadows.

[0097] Step 3002: Identify the friction surface 401 of the disk body 4 through the optical test module 201 to obtain the wear line 402 of the disk body 4.

[0098] Step 3003: Identify the surface profiles of all ribs and ribs 403 on the disk body 4 through the optical test module. Among them, the surface profiles at least include the outer surface 4032 of the ribs and ribs and the inner surface 4031 of the ribs and ribs.

[0099] In an embodiment of the present invention, based on the actual deformation data, the control system 3 calculates the wear data of the disk body 4, which specifically includes the following steps:

[0100] Step 4001: Compare the wear line 402 with the initial wear line 402 of the disk body 4 pre-stored in the computer module 302 to obtain the total wear value H of the disk body 4 a ;

[0101] Step 4003: As in Figure 3 and Figure 4 In the embodiments shown, measure the difference H between the outer surface 4032 of each rib and rib and the reference plane on , and the difference H between the inner surface 4031 of each rib and rib 403 and the reference plane in , where n is the total number of ribs and ribs;

[0102] Step 4003: Calculate the dish-shaped plastic deformation value H of the disk body 4 b and the twisted wave plastic deformation value H of the disk body 4 c ; Among them, the calculation formula is:

[0103] H b =(|H in -H on |)max;

[0104]

[0105] Specifically, take the upper surface 1041 of the test platform 104 as the reference plane. During the process of the test platform 104 driving the disk body 4 to rotate one week, identify the surface profiles of all ribs and ribs 403 on the disk body 4 to be tested through the optical test module 201. By measuring the difference H between the outer surface 4032 of all ribs and ribs 403 and the reference plane on , multiple groups of data can be obtained, which are respectively Ho1 , H o2 ……H on , the obtained data is compared with the design drawings of the disk body 4 of this model pre-stored in the computer module 302.

[0106] Similarly, measure the difference H between the inner surface 4031 of all ribs and ribs 403 on the disk body 4 and the reference plane in , multiple groups of data can be obtained, which are respectively H i1 , H i2 ……H in , the obtained data is compared with the design drawings of the disk body 4 of this model pre-stored in the computer module 302.

[0107] Set the measured values of the inner surface 4031 and the outer surface 4032 of the same rib and rib 403 as a set of data. Take the absolute value of the height difference (|H i -H o |) between the inner surface 4031 and the outer surface 4032 of the same rib and rib 403 as the disklike plastic deformation value of this rib and rib 403.

[0108] By selecting the absolute value of the height difference (|H i -H o |) between the inner surface 4031 and the outer surface 4032 of all ribs and ribs 403 on the disk body 4, the maximum value H b =(|H in -H on |)max is taken as the disklike plastic deformation value H b of the disk body 4.

[0109] Furthermore, by selecting the average value H in =(|H on -H d |) of the absolute value of the height difference (|H in -H on |) between the inner surface 4031 and the outer surface 4032 of all ribs and ribs 403 on the disk body 4, it is taken as the average value of the disklike plastic deformation value of the disk body 4.

[0110] By selecting the maximum value H o1 , H o2 ……H on and the minimum value H on min in H on , then H on max - H on min = H o扭 is the outer-side twisted wave plastic deformation value of the disk body 4. Similarly, H in max - H inmin = H i扭 is the inner side twisted wave plastic deformation value of the disk body 4.

[0111] Take the outer side twisted wave plastic deformation value H o扭 and the inner side twisted wave plastic deformation value H i扭 The average value of is used as the twisted wave plastic deformation value H of the disk body 4 c .

[0112] Take the total wear value H of the disk body 4 a , the disk-shaped plastic deformation value H of the disk body 4 b , and the twisted wave plastic deformation value H of the disk body 4 c Compare them with the specified standard values respectively to determine whether the disk body 4 meets the reuse standard.

[0123] After the position of the disk body 4 is fixed, the disk body 4 is fixed on the upper surface 1041 of the test platform 104 through the electromagnetic adsorption module.

[0124] Turn on the lighting module 202 through the computer module 302, and focus the light on the entire test platform 104, so that the cleaned disk body 4 is completely irradiated by the light, and there is no shadow in all directions of the disk body 4.

[0125] Load the test program on the computer module 302, and click the control button, for example, the start measurement / Start button, to start measuring the disk body 4.

[0126] Drive the test platform 104 to rotate by the rotation drive motor 105 to drive the disk body 4 to rotate one week. When the optical test module 201 scans the disk body 4 to obtain data, the test process is completed. The obtained measurement results are shown in Table 1.

[0127] Based on the data in Table 1, use the computer module 302 to calculate and obtain:

[0128] The total wear value H of the disk body 4 a = 1.1 mm;

[0129] The disc-shaped plastic deformation value H of the disk body 4 b = 1.594 mm;

[0130] The average disc-shaped plastic deformation value H of the disk body 4 d = 1.502 mm;

[0131] The twisted wave plastic deformation value H of the disk body 4 c = 0.1175 mm;

[0132] The inner twisted wave plastic deformation value H of the disk body 4 i扭 = 0.175 mm;

[0133] The outer twisted wave plastic deformation value H of the disk body 4 o扭 = 0.06 mm.

[0134] Save the measurement results of the computer module 302, and save the results correspondingly under the name of A n 's name.

[0135] Then use the computer module 302 to raise the test platform 104 and control the disk clamping mechanism 1042 to release the disk body 4.

[0136] Connect the disk body 4 to the sling, release the fixation of the electromagnetic adsorption module, and use the sling to remove the disk body 4 from the test platform 104.

[0137] Then the measurement operation of the next disk body 4 can be carried out.
