Description

Technical Field

[0001] The present invention belongs to the field of high - speed rail bushing processing, and specifically relates to a grinding device for high - speed rail bushings. Background Art

[0002] The development of rail transit in various countries is inconsistent. Due to different technical standards and development needs, many countries adopt different track gauges. Existing trains operating in China usually do not require a change in track gauge. When a train needs to operate across countries and the track gauges are different, the simplest way is to transfer passengers from one train to another. Currently, the passenger transport from Northeast China to Russia operates in this way. For freight transport, usually the entire train carriage is lifted, and then the train bogie is replaced. The inter - modal maintenance workshop at Erenhot Port in China operates in this way. For container shipments, an even simpler method is to directly lift and install the container onto another train. The Urumqi Concentration Center at Urumqi West Station in China uses this method to solve the problem of different track gauges during train operation.

[0003] To adapt to different track gauge requirements between different countries, a more direct solution is to develop a train that can operate between different track gauges, that is, the train wheels can slide according to the width of the track. This requires installing an oil - containing bushing required for sliding track gauge change between the train wheels and the axle.

[0004] The surface of the bushing needs to be ground to increase surface smoothness. When grinding the bushing, in order to ensure that the bushing can be ground comprehensively in place, usually the bushing is directly sleeved on the processing table. With such a setting, although during the grinding process, the bushing can rotate with the grinding wheel for comprehensive grinding, the grinding wheel rotates at a high speed, which also increases the danger level of the bushing during the processing. If the bushing is directly fixed, it is inconvenient to grind its various positions;

When the sliding sleeve rod 11 moves up and down, it can drive the control gear 21 to rotate;

[0029] As an embodiment of the present invention, a guiding ring 18 is fixedly connected to the bottom of the bushing seat 3, a plurality of fitting rings 19 are fixedly connected to the surface of the rotating disk 2, the guiding ring 18 and the fitting ring 19 are rotatably connected to each other, and the middle is vertically aligned with the axis of the support.

[0030] As an embodiment of the present invention, the guiding sliding plate 8 is perpendicular to the threaded shaft 10, the sliding rods 9 at the same end of the two threaded shafts 10 are fixedly connected to the bottom of the guiding sliding plate 8, and the sliding rods 9 respectively penetrate through the moving grooves 16.

[0038] The abutting block 4 is used to control the lifting of the lifting frame 6. Therefore, on the stable base 1, it is symmetrically arranged, and only two groups are provided, which control the lifting of the lifting frame 6 at intervals. When the stable base 1 rotates, when the bushing seat 3 at this position does not contact the lifting frame 6, the sliding sleeve rod 11 pushes the control gear 21 to rotate, and then the threaded shaft 10 rotates, driving the guiding sliding plates 8 to approach each other, pulling the two supporting blocks 7 closer, so that the bushing can be taken out or an unprocessed bushing can be replaced. The inner diameter of the bushing is sleeved on the surfaces of the two supporting blocks 7. When the rotating disk 2 continues to rotate to the next working station, the lifting frame 6 is squeezed by the abutting block 4 and moves upward. Then the sliding sleeve rod 11 pushes the control gear 21 to rotate in the reverse direction, and the two guiding sliding plates 8 can be separated from each other. Then the supporting blocks 7 contact the inner wall of the bushing and fix the inner wall of the bushing. When grinding, the bushing is driven to rotate by the grinding wheel. When rotating, the entire bushing seat 3 rotates along with it. The control gear 21 rotates around the sliding sleeve rod 11, which does not affect the locking of the supporting blocks 7. Rubber gaskets are respectively arranged on the mutually - remote sides of the supporting blocks 7, which are used to increase the friction with the inner wall of the bushing and also to prevent the supporting blocks 7 from excessively and rigidly squeezing the inner diameter of the bushing when the lifting frame 6 rises, causing the bushing to deform. The rubber gaskets are designed to have a certain deformation space.
