[0002] With the widespread use of locomotive equipment, the number of wheel-mounted brake discs used on locomotives has also increased rapidly. The wheel-mounted brake discs used on locomotives are high-speed rotating parts, which makes the wheel-mounted brake discs have higher requirements for residual unbalance. When the residual unbalance on the wheel-mounted brake disc is too large, it will increase the centrifugal force on the wheel, thus causing safety hazards to the driving process of the locomotive.

Obviously, the described embodiments are only part of the embodiments of the present invention, not 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.

[0041] Implementation Method 1

[0042] Please refer to Figure 1 and Figure 2 As shown, in an embodiment of the present invention, a wheel-mounted brake disc centering assembly mechanism 200 is provided, the wheel-mounted brake disc 100 includes a wheel 101, and two disc bodies 102 respectively arranged on both sides of the wheel 101, the wheel-mounted brake disc centering assembly mechanism 200 includes: a positioning tool 1, provided with a positioning platform 10 for supporting the wheel-mounted brake disc 100; a first brake disc positioning member 2 arranged on the positioning tool 1; a wheel positioning member 3 slidably arranged on the positioning tool 1, the wheel positioning member 3 and the first brake disc positioning member 2 are arranged on both sides of the positioning platform 10 opposite to each other; and a second brake disc positioning member 4 arranged on the positioning tool 1, the second brake disc positioning member 4 and the first brake disc positioning member 2 are spaced apart to form a wheel accommodating space 201, and the second brake disc positioning member 4 and the first brake disc positioning member 2 are arranged on both sides of the wheel accommodating space 201 in a centering manner.

[0043] In general, the centering and positioning process of the wheel-mounted brake disc centering assembly mechanism 200 is as follows: the wheel-mounted brake disc 100 is placed on the positioning platform 10 of the positioning tool 1, so that the wheel-mounted brake disc 100 is located in the wheel accommodating space 201. Then, the first brake disc positioning member 2 and the second brake disc positioning member 4 are used to center and position the disc bodies 102 on both sides of the wheel-mounted brake disc 100. Since the first brake disc positioning member 2 and the second brake disc positioning member 4 on the same wheel-mounted brake disc centering assembly mechanism 200 are centrally arranged on both sides of the wheel accommodating space 201, the first brake disc positioning member 2 and the second brake disc positioning member 4 can quickly center and position the two disc bodies 102 on both sides of the wheel 101.

[0044] In addition, the wheel positioning member 3 can be slidably arranged on the positioning tool 1. By adjusting the position of the wheel positioning member 3, the wheel positioning member 3 is abutted against the wheel 101 of the wheel-mounted brake disc 100 to adjust the relative position of the wheel 101, so that the centroid of the wheel 101 can coincide with the centroid of the disc body 102, thereby realizing the centering positioning process between the wheel 101 and the disc body 102.

[0045] In an embodiment of the present invention, the positioning tool 1 includes: a first slider 11, the upper end surface of the first slider 11 forms a positioning platform 10, and one end of the first slider 11 is provided with a first brake disc positioning member 2; a second slider 12, the second slider 12 is slidably arranged at the other end of the first slider 11, and the second slider 12 is provided with a wheel positioning member 3; and a third slider 13, the third slider 13 is detachably connected to the first slider 11, the third slider 13 is spaced apart from the first slider 11, and the third slider 13 is provided with a second brake disc positioning member 4.

[0046] During use, the third slider 13 is detachably connected to the first slider 11. When placing the wheel-mounted brake disc 100 to be processed, the third slider 13 can be removed first to form a falling channel for installing the wheel-mounted brake disc 100. After the wheel-mounted brake disc 100 is placed on the positioning platform 10, the third slider 13 can be installed back.

[0047] The first brake disc positioning member 2 arranged at one end of the first slider 11 can abut against the inner edge of the lower disc body 102 of the wheel-mounted brake disc 100, and the second brake disc positioning member 4 on the third slider 13 can abut against the inner edge of the upper disc body 102 of the wheel-mounted brake disc 100, thereby realizing the centering positioning of the upper disc body 102 and the lower disc body 102 by utilizing the first brake disc positioning member 2 and the second brake disc positioning member 4 arranged in a central manner.

[0048] Designers can adjust the shapes and sizes of the first slider 11 , the second slider 12 and the third slider 13 according to the use requirements of the wheel-mounted brake disc 100 . For example, each slider can be configured as a rectangular parallelepiped, and no specific limitation is made here.

[0049] In an embodiment of the present invention, a slide groove 111 is provided at the other end of the first slider 11, and the slide groove 111 is arranged along the extension direction of the first slider 11. The second slider 12 is slidably arranged in the slide groove 111. The upper end surface of the second slider 12 is not higher than the upper end surface of the first slider 11. A driving screw 5 is screwed on the first slider 11, and the driving screw 5 is connected to the second slider 12.

[0050] By arranging the second slider 12 in the slide groove 111 and guiding the second slider 12 by the slide groove 111, the movement stability of the second slider 12 is improved. Moreover, when the wheel-mounted brake disc 100 is placed on the first slider 11, since the upper end surface of the second slider 12 is not higher than the upper end surface of the first slider 11, the second slider 12 is driven to slide by the driving screw 5 without affecting the wheel-mounted brake disc 100.

[0051] Furthermore, the designer may also set scale marks on the driving screw 5 so as to know the pushing stroke of the driving screw 5 to better control the displacement of the second sliding block 12 .

[0052] In an embodiment of the present invention, the first brake disc positioning member 2 includes a first pin shaft 21 arranged on the first slider 11, and the second brake disc positioning member 4 includes a second pin shaft 41 arranged on the third slider 13. The first pin shaft 21 and the second pin shaft 41 have a coaxially arranged centered positioning state. In the centered positioning state, the axis between the first pin shaft 21 and the second pin shaft 41 is perpendicular to the positioning platform 10.

[0053] Specifically, the first pin shaft 21 and the second pin shaft 41 are set to have the same diameter. Designers can determine the diameters of the first pin shaft 21 and the second pin shaft 41 according to usage requirements, and no specific restrictions are made here.

[0054] In the embodiment of the present invention, the wheel locating member 3 includes a third pin shaft 31 arranged on the second sliding block 12 , and the third pin shaft 31 and the first pin shaft 21 are arranged on both sides of the positioning platform 10 opposite to each other.

[0055] Designers can determine the diameter of the third pin shaft 31 according to usage requirements. For example, the third pin shaft 31 and the first pin shaft 21 are set to have the same diameter, and no specific limitation is made here.

[0056] In a specific embodiment, the third pin shaft 31 is parallel to the first pin shaft 21 and is arranged at the same height. By arranging the third pin shaft 31 in parallel with the first pin shaft 21, the first pin shaft 21 and the third pin shaft 31 can clamp the wheel-mounted brake disc 100 along the laying direction of the positioning platform 10, which has a better positioning and clamping effect and avoids bending stress on the wheel-mounted brake disc 100.

[0057] In an embodiment of the present invention, in the centered positioning state, the first pin 21 can abut against the inner edge of one of the discs 102 , the second pin 41 can abut against the inner edge of the other disc 102 , and the third pin 31 can controllably abut against the outer edge of the wheel 101 .

[0058] The first pin 21 and the second pin 41 both have arc-shaped side walls, which can better fit the annular inner edge of the disc body 102, and the third pin 31 can form point-line contact with the outer edge of the wheel 101 through the arc-shaped side walls. By adjusting the stroke of the driving screw 5, the first pin 21, the second pin 41 and the third pin 31 can evenly contact the disc body 102 and the wheel 101, thereby achieving the centroid alignment of the wheel-mounted brake disc 100. And the first pin 21, the second pin 41 and the third pin 31 can cooperate to clamp the wheel-mounted brake disc 100 at three points, with better centering and positioning accuracy.

[0059] Designers can set the first pin 21, the second pin 41 and the third pin 31 to other shapes according to usage requirements, and no specific limitation is made here.

[0060] In the embodiment of the present invention, a protruding support portion 112 is provided at the other end of the first slider 11 , a fourth pin 6 is provided at one end of the third slider 13 , and the third slider 13 is detachably connected to the support portion 112 via the fourth pin 6 .

[0061] Specifically, the support portion 112 is rod-shaped and perpendicular to the positioning platform 10 . The third slider 13 is detachably connected to the support portion 112 via the fourth pin 6 , and the third slider 13 is parallel to the positioning platform 10 .

[0062] The fourth pin shaft 6 can efficiently realize the installation and disassembly process between the third slider 13 and the support portion 112 , so that by disassembling the third slider 13 , a falling channel for installing the wheel-mounted brake disc 100 can be quickly formed to place the wheel-mounted brake disc 100 on the positioning platform 10 .

[0063] Implementation Method 2

[0064] Please refer to Figure 3 As shown, an embodiment of the present invention further provides a wheel-mounted brake disc centering assembly device, comprising a plurality of groups of wheel-mounted brake disc centering assembly mechanisms 200 as described in the first embodiment, wherein the plurality of groups of wheel-mounted brake disc centering assembly mechanisms 200 are arranged in an interval ring.

[0065] The specific structure, working principle and beneficial effects of the wheel-mounted brake disc centering assembly mechanism 200 are the same as those in the first embodiment, and will not be described in detail here. The wheel-mounted brake disc centering assembly device is provided with multiple sets of wheel-mounted brake disc centering assembly mechanisms 200, and the wheel-mounted brake disc 100 is centered and positioned by using multiple sets of wheel-mounted brake disc centering assembly mechanisms 200 in a coordinated manner, so that the center of mass of the wheel-mounted brake disc 100 can coincide with the centroid after assembly, reducing the residual unbalance of the wheel-mounted brake disc 100, ensuring the stability of the wheel-mounted brake disc 100 during high-speed movement, improving the vibration quality during the driving of the locomotive, and improving the operating safety of the locomotive.

[0066] Furthermore, during the use of the wheel-mounted brake disc centering assembly mechanism 200 , there is no need to preset positioning holes on the wheel-mounted brake disc 100 , thereby ensuring the integrity of the wheel 101 and the disc body 102 and improving the overall strength of the wheel 101 and the disc body 102 .

[0067] Designers can adjust the number of wheel-mounted brake disc centering assembly mechanisms 200 according to the centering and positioning requirements of the wheel-mounted brake disc 100, such as 3 groups, 4 groups or more groups, which is not specifically limited here.

[0068] In the valve implementation mode of the present invention, the wheel-mounted brake disc centering assembly device further comprises a support 7, a plurality of sets of wheel-mounted brake disc centering assembly mechanisms 200 are arranged along the circumferential annular array of the support 7, and each positioning platform 10 is arranged at the same height.

[0069] Specifically, a mounting platform 71 is provided on the top of the support 7, and a plurality of wheel-mounted brake disc centering assembly mechanisms 200 are arranged in a circular array on the mounting platform 71. Designers can adjust the size of the wheel-mounted brake disc centering assembly mechanism 200 according to the size of the wheel 101 and the disc body 102, and no specific limitation is made here.

[0070] In a specific embodiment, three groups of wheel-mounted brake disc centering assembly mechanisms 200 are provided in a circular array, and each wheel-mounted brake disc centering assembly mechanism 200 is disposed on the mounting platform 71 at intervals of 120°.

[0071] The wheel-mounted brake disc 100 to be processed is placed on the positioning platform 10 of the three sets of wheel-mounted brake disc centering assembly mechanisms 200. The first pins 21 in the three sets of wheel-mounted brake disc centering assembly mechanisms 200 are all abutted against the inner edge of the lower disc body 102 of the wheel-mounted brake disc 100, and the lower disc body 102 is positioned by a three-point positioning method. The second pins 41 in the three sets of wheel-mounted brake disc centering assembly mechanisms 200 are all abutted against the inner edge of the upper disc body 102 of the wheel-mounted brake disc 100, and the upper disc body 102 is positioned by a three-point positioning method. Through the cooperation of each first pin 21 and each second pin 41, the upper disc body 102 and the lower disc body 102 are positioned at multiple points, thereby ensuring the centering accuracy between the upper disc body 102 and the lower disc body 102.

[0072] Furthermore, by rotating each driving screw 5 to push the second slider 12 to slide on the first slider 11, the position of each third pin 31 is adjusted, so that each third pin 31 is evenly abutted against the outer edge of the wheel 101, and the wheel 101 is positioned by three-point positioning. By using the driving screw 5 to control the relative position of each third pin 31, the centroid of the wheel 101 and the centroid of the disc body 102 are overlapped in the height direction. Then, the wheel 101 and the disc bodies 102 on both sides are fixedly installed to form a wheel-mounted brake disc 100, thereby ensuring that the centroid and the center of mass of the wheel-mounted brake disc 100 coincide.

[0073] By arranging multiple sets of wheel-mounted brake disc centering assembly mechanisms 200 in a circular array, the multiple sets of wheel-mounted brake disc centering assembly mechanisms 200 can cooperatively support the wheel-mounted brake disc 100, and perform multi-point centering positioning of the wheel-mounted brake disc 100 along the circumference of the wheel-mounted brake disc 100, thereby significantly improving the accuracy of the centering positioning, ensuring that the centroid and center of mass of the wheel 101 and the disc body 102 on the wheel-mounted brake disc 100 coincide with each other, and reducing the residual imbalance on the wheel-mounted brake disc 100.
