Description

Technical Field

[0001] The present application relates to the technical field of polishing and grinding of locomotive wheels, and in particular to a polishing and grinding device for locomotive wheels. Background Art

[0002] Locomotives are generally driven directly or through transmission devices by power machinery such as steam engines, diesel engines, gas turbines, and traction motors. The power machinery generates torque on the locomotive wheels, and at the same time, the road gives the wheels an equal and opposite reaction force. The locomotive wheels also need to be polished after preliminary milling.

[0003] However, there are the following problems in the prior art:

[0004] 1. The grinding and polishing of locomotive wheels after milling is usually done by workers fixing a single locomotive wheel and grinding and polishing the locomotive wheel manually or through an automated mechanism. This method has low work efficiency and is not suitable for grinding and polishing batches of locomotive wheels.

It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0052] See also Figures 1 to 7The embodiment of the present application provides a locomotive wheel polishing and grinding device, including: a workbench 1, a processing mechanism, a clamping and fixing mechanism, a supporting mechanism and a lifting mechanism, a plurality of supporting legs 14 are provided at the bottom of the workbench 1, a processing table 4 is provided on the workbench 1, a first conveying mechanism 11 and a second conveying mechanism 12 are provided on both sides of the processing table 4, a locomotive wheel 3 is provided on the first conveying mechanism 11 and the processing table 4, a group of guide plates 13 are provided on the first conveying mechanism 11 and the second conveying mechanism 12, a mounting cavity is provided in the processing table 4, a lifting column 6 is coaxially provided on the processing table 4, and a cavity is provided in the lifting column 6;

[0053] The effect of such arrangement is that the locomotive wheels 3 after batch milling are placed on the first conveying mechanism 11 in sequence, and the locomotive wheels 3 are neatly arranged on the first conveying mechanism 11 through a group of guide plates 13. As the first conveying mechanism 11 conveys the locomotive wheels 3, when the locomotive wheels 3 are conveyed to one end of the first conveying mechanism 11 close to the processing table 4, the first conveying mechanism 11 stops working to facilitate the grinding and polishing of the batch of locomotive wheels 3, and the work efficiency is high.

[0054] See also Figures 1 to 3 , the processing mechanism is arranged on the workbench 1, and the processing mechanism includes a grinding tool 251 for polishing and grinding the surface of the locomotive wheel 3; the processing mechanism also includes a group of support frames 2, a first linear motor 21, a first slide rail 211, a moving frame 22, a second linear motor 221, a moving table 23, a lifting cylinder 24, a first drive motor 25, a clamping claw 26 and an adjusting cylinder 27; a group of support frames 2 are symmetrically arranged on the workbench 1, the first linear motor 21 and the first slide rail 211 are respectively arranged on a group of support frames 2, the output end of the first linear motor 21 is fixedly connected to one end of the moving frame 22, and the other end of the moving frame 22 slides on the first slide rail 211;

[0055] The second linear motor 221 and the moving platform 23 are arranged on the moving frame 22, the output end of the second linear motor 221 is fixedly connected to the moving platform 23, the moving frame 22 is provided with a limit rail, and the moving platform 23 is provided with a slide table adapted to the limit rail;

[0056] The lifting cylinder 24 and the clamping claw 26 are respectively fixedly mounted on both ends of the moving platform 23. The end of the lifting cylinder 24 close to the workbench 1 is provided with a mounting plate, and a plurality of mounting shaft blocks are provided on the mounting plate. The first drive motor 25 and the adjusting cylinder 27 are respectively rotatably connected to the mounting plate through the plurality of mounting shaft blocks. The end of the adjusting cylinder 27 away from the mounting shaft blocks is rotatably connected to the first drive motor 25. The output end of the first drive motor 25 is coaxially fixedly connected to the grinding tool 251.

[0057] The effect of such arrangement is that by controlling the output ends of the first linear motor 21 and the second linear motor 221 to work, the clamping claws 26 on the moving table 23 clamp the locomotive wheel 3 to the processing table 4 at a fixed point, which facilitates the grinding and polishing of batches of locomotive wheels 3 with high work efficiency;

[0058] The grinding tool 251 is controlled to polish and grind the surface of the locomotive wheel 3 by controlling the output end of the lifting cylinder 24 and the adjusting cylinder 27. The lifting cylinder 24 is used to control the height of the grinding tool 251 on the surface of the locomotive wheel 3, and the adjusting cylinder 27 is used to control the cutting angle of the grinding tool 251 on the surface of the locomotive wheel 3.

[0059] See also Figure 4 and Figure 6 , the clamping and fixing mechanism is arranged on the workbench 1, and the clamping and fixing mechanism is used to automatically fix the locomotive wheel 3; the clamping and fixing mechanism comprises: a plurality of bidirectional screws 5, a plurality of first bevel gears 51, a plurality of clamping blocks 52, a second bevel gear 53, a third bevel gear 54, a second drive motor 55 and a fourth bevel gear 56, a plurality of slide grooves 41 are provided in a circular array on the processing table 4, a plurality of bidirectional screws 5 and a plurality of clamping blocks 52 are respectively provided in the plurality of slide grooves 41, a group of clamping blocks 52 respectively corresponds to the thread of the bidirectional screw 5 and is provided with threaded holes adapted thereto, and a plurality of first bevel gears 51 are respectively coaxially fixedly connected with the plurality of bidirectional screws 5;

[0060] The second bevel gear 53 and the third bevel gear 54 are coaxially fixedly connected, and the second bevel gear 53 is coaxially rotatably connected with the processing table 4, the second bevel gear 53 is meshed with the plurality of first bevel gears 51, the second drive motor 55 is fixedly installed on the workbench 1, the output end of the second drive motor 55 is coaxially fixedly connected with the fourth bevel gear 56, and the fourth bevel gear 56 is meshed with the third bevel gear 54 for transmission;

[0061] The effect of such arrangement is that the fourth bevel gear 56 is driven by the output end of the second drive motor 55 to engage with the third bevel gear 54 for transmission. Since the second bevel gear 53 is coaxially fixedly connected with the third bevel gear 54, the second bevel gear 53 drives multiple first bevel gears 51 to rotate synchronously, thereby causing the bidirectional screw 5 coaxially fixedly connected with the first bevel gear 51 to rotate. In this way, a group of clamping blocks 52 in the slide groove 41 are respectively limited by the threaded holes and the slide groove 41, and move relatively on the bidirectional screw 5, so that multiple groups of clamping blocks 52 can clamp and fix the edge protrusion at the bottom of the locomotive wheel 3, without the need for staff to manually fix it with a clamp, and the operation is simple and convenient.

[0062] See also Figures 5 to 7The support mechanism is arranged in the cavity of the lifting column 6, and the support mechanism is used to support and abut the inner wall of the locomotive wheel 3; the support mechanism includes: a fourth drive motor 8, a first spur gear 81, a second spur gear 82, a fixing member 83, a plurality of T-shaped support members 84, a plurality of slide bars 842 and a plurality of limit blocks 85, the fourth drive motor 8 and the fixing member 83 are both fixedly installed in the cavity of the lifting column 6, the second spur gear 82 is rotatably connected to the fixing member 83, the output end of the fourth drive motor 8 is coaxially fixedly connected to the first spur gear 81, and the first spur gear 81 is meshed with the second spur gear 82 for transmission;

[0063] The side wall of the lifting column 6 is provided with a plurality of guide holes 62, and the plurality of guide holes 62 are all connected with the cavity of the lifting column 6. A plurality of T-shaped support members 84 are respectively arranged in the plurality of guide holes 62. A plurality of guide limit grooves are provided on the fixing member 83, and the plurality of T-shaped support members 84 slide in the plurality of guide limit grooves respectively. A plurality of slide bars 842 are respectively fixedly connected with the plurality of T-shaped support members 84. A plurality of guide arc grooves 821 are provided on the second spur gear 82, and the plurality of slide bars 842 are respectively clamped in the plurality of guide arc grooves 821. The limit block 85 is fixedly connected with one end of the slide bar 842 away from the T-shaped support member 84.

[0064] In this way, after the grinding tool 251 performs preliminary polishing on the surface of the locomotive wheel 3, the edge protrusion fixed by the clamping block 52 has not been polished yet. At this time, the output end of the second drive motor 55 rotates in the opposite direction, so that the fourth bevel gear 56 and the third bevel gear 54 are meshed and transmitted, and the locomotive wheel 3 is loosened. At this time, the first spur gear 81 and the second spur gear 82 are driven to mesh and transmit through the output end of the fourth drive motor 8. Since the fixing member 83 is fixed in the lifting column 6, when the second spur gear 82 rotates, the guide arc groove 821 pushes the slide bar 842 gradually away from the center of the second spur gear 82. At this time, the slide bar 842 drives the T-shaped support member 84 to extend outward from the guide hole 62 of the lifting column 6, and the rubber pad 841 on the T-shaped support member 84 is against the inner side wall of the locomotive wheel 3.

[0065] See also Figure 6 , the lifting column 6 is coaxially arranged with the locomotive wheel 3, and a rubber pad 841 is provided at one end of the T-shaped support member 84 away from the second spur gear 82;

[0066] The effect of such arrangement is that, by arranging a rubber pad 841 at one end of the T-shaped support 84 away from the second spur gear 82 , the contact friction between the plurality of T-shaped support members 84 and the locomotive wheel 3 is increased, making it easier for the lifting mechanism to lift the locomotive wheel 3 .

[0067] See also Figure 5A movable groove 42 is provided in the cavity of the processing table 4, and a lifting mechanism is arranged in the mounting cavity of the processing table 4. The lifting mechanism is used to lift the locomotive wheel 3, so that the grinding tool 251 can grind the fixed part of the bottom of the locomotive wheel 3; the lifting mechanism includes: a hydraulic cylinder 7, a guide slider 71 and a rotating assembly, the hydraulic cylinder 7 is fixedly installed in the mounting cavity of the processing table 4, the guide slider 71 is arranged in the movable groove 42, the output end of the hydraulic cylinder 7 is rotatably connected to the lifting column 6, the output end of the hydraulic cylinder 7 is fixedly connected to the guide slider 71, and the end of the lifting column 6 close to the workbench 1 is coaxially fixedly connected with a fifth bevel gear 61;

[0068] The rotating assembly is arranged on the guide slider 71, and the rotating assembly includes: a third driving motor 72 and a sixth bevel gear 73. The third driving motor 72 is fixedly mounted on the guide slider 71, and the output end of the third driving motor 72 is coaxially fixedly connected with the sixth bevel gear 73, and the sixth bevel gear 73 is meshed with the fifth bevel gear 61 for transmission;

[0069] The effect of such arrangement is that the lifting column 6 is lifted up by the output end of the hydraulic cylinder 7, at which time the edge protrusion at the bottom of the locomotive wheel 3 is exposed, and then the sixth bevel gear 73 is driven by the output end of the third drive motor 72 to mesh with the fifth bevel gear 61 for transmission, so that the lifted lifting column 6 drives the locomotive wheel 3 supported by multiple T-shaped support members 84 to rotate, which is convenient for the grinding tool 251 to grind the edge protrusion at the bottom of the locomotive wheel 3. Since the output end of the hydraulic cylinder 7 is coaxially rotatably connected with the bottom end of the lifting column 6, and the guide slider 71 is fixedly connected to the output end of the hydraulic cylinder 7, the guide slider 71 is driven to move in the moving groove 42 while the lifting column 6 is lifted up, so that there is no motion interference between the lifting component and the rotating component of the lifting column 6, and the structural design is reasonable and effective.

[0070] From the above, we can see that the working principle of this application is as follows:

[0071] The locomotive wheels 3 after batch milling are sequentially placed on the first conveying mechanism 11, and the locomotive wheels 3 are neatly arranged on the first conveying mechanism 11 through a group of guide plates 13. When the locomotive wheels 3 are conveyed to one end of the first conveying mechanism 11 close to the processing table 4 as the first conveying mechanism 11 conveys, the first conveying mechanism 11 stops working, and the output ends of the first linear motor 21 and the second linear motor 221 are controlled to work, so that the clamping claws 26 on the moving table 23 clamp the locomotive wheels 3 on the processing table 4 at a fixed point;

[0072] The output end of the second driving motor 55 drives the fourth bevel gear 56 to mesh with the third bevel gear 54 for transmission. Since the second bevel gear 53 is coaxially fixedly connected with the third bevel gear 54, the second bevel gear 53 drives the plurality of first bevel gears 51 to rotate synchronously, thereby rotating the bidirectional screw 5 coaxially fixedly connected with the first bevel gear 51. In this way, a group of clamping blocks 52 in the slide groove 41 are respectively limited by the threaded holes and the slide groove 41, and relatively move on the bidirectional screw 5, so that the plurality of groups of clamping blocks 52 clamp and fix the edge protrusion at the bottom of the locomotive wheel 3;

[0073] The grinding tool 251 is controlled to polish the surface of the locomotive wheel 3 by controlling the output end of the lifting cylinder 24 and the regulating cylinder 27. The lifting cylinder 24 is used to control the height of the grinding tool 251 on the surface of the locomotive wheel 3, and the regulating cylinder 27 is used to control the cutting angle of the grinding tool 251 on the surface of the locomotive wheel 3.

[0074] After the grinding tool 251 performs preliminary polishing on the surface of the locomotive wheel 3, the edge protrusion fixed by the clamping block 52 has not been polished yet. At this time, the output end of the second drive motor 55 rotates in the opposite direction, so that the fourth bevel gear 56 and the third bevel gear 54 are meshed and transmitted, and the locomotive wheel 3 is loosened. At this time, the first spur gear 81 and the second spur gear 82 are driven to mesh and transmit through the output end of the fourth drive motor 8. Since the fixing member 83 is fixed in the lifting column 6, when the second spur gear 82 rotates, the guide arc groove 821 pushes the slide bar 842 gradually away from the center of the second spur gear 82. At this time, the slide bar 842 drives the T-shaped support member 84 to extend outward from the guide hole 62 of the lifting column 6, and the rubber pad 841 on the T-shaped support member 84 abuts against the inner wall of the locomotive wheel 3;

[0075] The lifting column 6 is lifted up by the output end of the hydraulic cylinder 7, at which time the edge protrusion at the bottom of the locomotive wheel 3 is exposed, and then the sixth bevel gear 73 is driven by the output end of the third drive motor 72 to engage and transmit with the fifth bevel gear 61, so that the lifted lifting column 6 drives the locomotive wheel 3 supported by multiple T-shaped support members 84 to rotate, which is convenient for the grinding tool 251 to grind the edge protrusion at the bottom of the locomotive wheel 3.

[0076] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
