Description

Technical Field

[0001] The present invention relates to the field of rail transportation, and in particular to a component grinding device, application and grinding method. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] Rail vehicle axles need to undergo multiple inspections during their life cycle. Due to varying degrees of damage to the axles during operation, each grinding and inspection will reduce the diameter of the axle. When the axle diameter cannot meet the size range, the axle will be scrapped.

[0004] To ensure the life of the axle and avoid excessive grinding that could cause the axle to fail, only the defective parts are ground and repaired during the inspection process. For these reasons, the current axle inspection and repair process is done manually. After the axle is placed on the inspection table, the axle is manually rotated to grind and repair the defects around the axle body.

[0005] The existing axle maintenance method is relatively traditional, requiring manual grinding while rotating the axle, resulting in low maintenance efficiency. Moreover, to avoid polygonal shapes caused by partial grinding of the axle, the operation must be performed by experienced personnel, which places certain requirements on the production staff's skill level. There are also some axle grinding devices in the existing solutions. The grinding parts are driven by a multi-directional motion mechanism. It takes a certain amount of time for the grinding parts to move from the starting position to the grinding point. In addition, the position of the grinding parts needs to be adjusted repeatedly by manual labor to ensure that the grinding parts reach the grinding point accurately. The response speed is slow and the grinding parts occupy a large space. If manual adjustment is not performed, the grinding parts need to be polished from beginning to end, which wastes time. The support of the axle mainly relies on the end structural parts, which have high requirements for the end structural parts, resulting in great difficulties in axle installation. In addition, the axle specifications of different rail vehicles vary, resulting in different axle lengths and diameters for different models. However, the versatility of existing equipment is poor, and different equipment is required for different axles. A large number of axles need to be inspected at a time, and existing inspection equipment can usually only inspect one axle at a time. In order to improve the inspection efficiency, multiple machines need to be set up, which not only increases the inspection cost, but also takes up a large amount of space for all equipment.

Two multi-link mechanisms 3 are set on the bracket 9. The two multi-link mechanisms 3 are staggered at the installation point of the bracket 9. The two multi-link mechanisms are set opposite to each other. One multi-link mechanism 3 is used to drive the corresponding grinding part 2 to grind the axle 4 on one side, and the other multi-link mechanism 3 is used to drive the corresponding grinding part 2 to grind the axle 4 on the other side. In this way, the bracket 9 is fully utilized to avoid interference between the two and improve space utilization.

A brush is fixed to the side of the axle support 38. The brush is set upward to clean the dirt on the surface of the axle 4 to prevent the dirt from damaging the axle surface. It should be noted that one end of the anti-slip safety rope 7 is fixed to the inner side of the axle support 38, and the other end of the anti-slip safety rope 7 can be passed around the axle 4 and then detachably fixed to the outer side of the axle support 38 to prevent the axle 4 from falling out due to failure of the fixation at both ends of the axle. Specifically, a fixing ring is provided on the outer side of the axle support 38, and an openable lock is provided on the fixing ring. One end of the anti-slip safety rope 7 is connected to the lock, and the lock can be opened relative to the fixing ring.
