Description

Technical Field

[0001] The utility model relates to the field of high-speed rail EMU maintenance, and more specifically, relates to a turnover mechanism for grinding small parts of high-speed rail axle boxes. Background Art

[0002] In the field of rail transit equipment operation and maintenance, the high-speed rail axle box, as a core component ensuring the driving safety of trains, the stable operation of its internal bearings directly determines the dynamic performance and driving reliability of the train. Small components supporting the axle box (such as axle box covers, sealing rings, connecting bolts, etc.), as key protection and auxiliary structures for the bearing operating environment, are long exposed to complex working conditions such as vibration, dust and humidity changes generated during train operation, and rust layers are easily formed on their surfaces. If the rust layer is not removed in time, it will not only reduce the assembly accuracy of the small components, but also may cause rust debris to fall off during subsequent use, enter the interior of the axle box and cause failures such as bearing wear and jamming, and in severe cases, even lead to safety accidents such as axle box overheating and train outage. Therefore, it is necessary to regularly grind and derust the small components supporting the high-speed rail axle box in the high-level overhaul of locomotives, so as to ensure the normal operation of the bearings inside the axle box.

[0003] At present, for the grinding and derusting operation of small components supporting high-speed rail axle boxes, the traditional operation mode of "manually holding grinding tools + manual turnover" is still dominant in the industry. This mode has the following prominent problems in practical application:

[0004] First, the manual turnover operation leads to low operation efficiency. Due to the large variety and models of small components supporting high-speed rail axle boxes (the structural dimensions and shapes of the small components corresponding to different train models and different axle box specifications are significantly different, such as circular sealing rings, square connecting blocks, special-shaped positioning parts, etc.), and most of the small components need to be ground and derusted on multiple surfaces (such as front and back surfaces, side vertical surfaces), the operator needs to manually stop the grinding operation, adjust the posture of the small component and re-fix it after completing the grinding of one surface, and then start the grinding process. In this process, the non-grinding auxiliary operation time accounts for as high as 30%-50%, which severely restricts the overall grinding operation efficiency and is difficult to meet the capacity demand in large-scale operation and maintenance scenarios.

[0005] Second, manual turnover causes excessive physical consumption of operators. Some small components supporting high-speed rail axle boxes (such as large axle box covers, metal connecting brackets, etc.) can weigh 5-15kg. During the grinding process, operators need to frequently bend down, raise their hands, and turn over the components, and maintain a high degree of concentration to avoid component slipping or positioning deviation. Long-term repeated such high-intensity physical operations are likely to cause occupational health problems such as lumbar strain and arm muscle fatigue for operators, and at the same time, the accuracy of subsequent turnover operations will be reduced due to physical decline, increasing the risk of unqualified grinding quality of small components.

[0006] Furthermore, the prior art lacks an automatic flipping solution adapted to multi-model small components. At present, although there are a small number of semi-automatic grinding equipment for single-model standardized components in the industry, the flipping mechanisms of such equipment are mostly of fixed structural design, which can only adapt to small components of specific sizes and shapes, and cannot be flexibly adjusted to meet the flipping requirements of small components of different categories and models. For the small components supporting high-speed rail axle boxes with diverse models and complex structures, the existing semi-automatic equipment has poor universality, still relies on manual-assisted flipping, and cannot fundamentally solve the problems of efficiency and physical energy consumption caused by manual flipping.

[0007] In addition, manual flipping easily leads to insufficient stability of grinding quality. Due to differences in the flipping force and angle control of different operators, and flipping positioning deviation is prone to occur after physical energy consumption, which leads to problems such as uneven grinding allowance on each surface of the small component and missed grinding in some areas, affecting the surface accuracy and anti-rust effect of the small component. The grinding quality of the small components supporting the axle box is directly related to the sealing performance and service life of the axle box bearing, and unstable quality will pose hidden dangers to the driving safety of the train.

[0008] In summary, in the current grinding and derusting operation of small components supporting high-speed rail axle boxes, due to the lack of an automatic flipping mechanism adapted to multi-model small components, the problems such as low efficiency of manual flipping operation, high physical energy consumption of operators, and poor stability of grinding quality are prominent, which has become a key bottleneck restricting the efficient, safe and high-quality development of the rail transit equipment operation and maintenance industry.

[0010] The purpose of the present utility model is achieved through the following technical solutions.

[0011] A flipping mechanism for grinding small components of high-speed rail axle boxes, comprising a support frame, the support frame is provided with a longitudinal movement assembly, the longitudinal movement assembly is provided with a transverse movement assembly that can move longitudinally therewith, a rotation module capable of realizing relative rotation between the longitudinal movement assembly and the transverse movement assembly is arranged between the longitudinal movement assembly and the transverse movement assembly, and the transverse movement assembly is provided with two small component grippers driven by it.

[0012] Furthermore, the longitudinal movement component includes two upright plates disposed opposite each other on the same side of the support frame. Each upright plate is provided with a longitudinal guide rail on its outer side, and each longitudinal guide rail is provided with a longitudinal slider. A longitudinal movement connecting plate is connected between the two sets of longitudinal sliders. The bottom of the longitudinal movement connecting plate is fixedly connected to the top of the servo lifting module, and the bottom of the servo lifting module is fixedly connected to the support frame.

[0013] Furthermore, the lateral movement component includes a fixed frame, one side of which is fixedly connected to the rotation module, and the other side is provided with two lateral guide rails. Each lateral guide rail is provided with two lateral sliders, and each lateral slider is provided with a lateral slider connecting plate for connecting a small part gripper on its outer side. A lateral movement module is provided between the two lateral guide rails.

[0014] Furthermore, the two small component grippers are arranged horizontally relative to each other, and each small component gripper is connected to the lateral movement assembly via a gripper connecting plate.

[0015] Compared with the prior art, the beneficial effects of the technical solution of this utility model are:

[0016] (1) This utility model adopts a transverse moving component, which can realize the gripping and releasing function of the small part gripper on the axle box small part. The small part gripper can also be compatible with axle box small parts of various types and sizes.

[0017] (2) This utility model adopts a rotating module, which can realize the overall rotation function of the horizontal moving component and the small part gripper, thereby completing the flipping of the gripped axle box small part.

[0018] (3) This utility model adopts a longitudinal moving component, which can realize the lifting function of small parts. The servo lifting module can be raised to avoid interference, ensuring that it does not interfere with the rest of the structure when rotating.

[0019] This invention enables automatic flipping of various types of axle box components through the cooperation of the aforementioned lateral movement component, rotation module, and longitudinal movement component. This solves the problems of severe physical exhaustion, low efficiency, and difficulty in compatibility with multiple types of small components during the existing axle box component grinding process, while also ensuring the stability of grinding quality.
