Description

Technical Field

[0001] This utility model relates to the field of grinding technology for railway passenger car wheel axle axle box, and more specifically, to a grinding device for the end cover of railway passenger car wheel axle axle box. Background Technology

[0002] The axle box end cover of a railway passenger car wheel is a core component connecting the wheelset and the bogie frame. Its function is to support the weight of the car body, transmit loads, achieve wheelset positioning, and ensure the smoothness and safety of vehicle operation. Modern passenger cars generally use sealed double-row tapered roller bearings or cylindrical roller bearings, with built-in grease and integrated temperature sensors to monitor the operating status in real time.

[0003] See Figure 1 As shown, the third surface 4 of the end cover 1 of the axle box has a certain downward bending deformation and is irregular. When grinding by hand, the worker needs to adjust the grinding angle of the angle grinder according to the amount of deformation of the third surface 4. During the grinding process, the deformed part cannot be ground due to space limitations. In addition, the working environment is too poor, the noise is too loud, and there is too much dust, which affects the health of the workers.

[0004] In view of this, the present invention is proposed to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a grinding device for the end cover of the axle box of railway passenger cars, so as to solve the technical problem that when grinding the end cover of the axle box manually, the grinding surface is irregular and the grinding of the space-restricted area cannot be completed.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A grinding device for the end cover of axle box of a railway passenger car wheel axle includes a grinding mechanism, the grinding mechanism comprising: Mounting base, on which a drive motor is installed; The drive mechanism includes a drive synchronous pulley mounted on a drive motor and a transmission synchronous pulley rotatably mounted on a mounting base. The drive synchronous pulley and the transmission synchronous pulley are mounted with the same mating synchronous belt. An adjustable grinding head includes a cup-shaped wire brush. The bottom of the cup-shaped wire brush is connected to a cup-shaped wire brush mounting base. The bottom of the cup-shaped wire brush mounting base is connected to a drive shaft through a spherical joint. The drive shaft is coaxially and fixedly connected to a synchronous belt pulley.

[0007] Furthermore, the mounting base is an L-shaped mounting plate, which includes a long arm and a short arm connecting the long arm. The short arm is set vertically downward, the drive motor is fixedly mounted on the short arm, and the transmission timing pulley is rotated on the long arm.

[0008] Furthermore, it also includes a lifting cylinder, the output end of which is fixedly connected to the bottom of the long arm via a mounting component.

[0009] Furthermore, the mounting component includes a frame having a lower support beam and an upper support beam, and the bottom of the lifting cylinder is mounted on the lower support beam via a tailstock; A lifting guide sleeve is vertically installed at the bottom of the upper support beam. A lifting guide column is coaxially and fixedly connected to the output end of the lifting cylinder. The lifting guide column is slidably set inside the lifting guide sleeve, and the upper end of the lifting guide column is fixedly connected to the bottom of the long arm.

[0010] Furthermore, the timing belt is fitted with a brush arm, which is fixed to the long arm.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. When grinding the third side of the axle box end cover, control the drive motor to start. The drive motor drives the drive synchronous pulley to rotate through its output shaft. The rotation of the drive synchronous pulley drives the transmission synchronous pulley to rotate synchronously through the synchronous belt. The rotation of the transmission synchronous pulley drives the cup-shaped steel wire brush to rotate, grinding and removing rust from the axle box.

[0012] 2. When grinding curved, irregular, or space-constrained areas, the spherical joint connects to the drive shaft, allowing the cup-shaped wire brush to fit into the curved or irregular areas or reach into space-constrained areas for grinding. This improves grinding efficiency and effect, eliminates the need for workers to use an angle grinder, reduces labor intensity, and avoids harm to workers' health caused by dust.

[0015] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0016] See Figures 1 to 3 As shown, a grinding device for the end cover of axle box of a railway passenger car wheel axle includes a grinding mechanism. The grinding mechanism includes a mounting base 6, a drive mechanism, and an adjustable grinding head. A drive motor 7 is mounted on the mounting base 6. The drive mechanism includes a drive synchronous pulley 8 mounted on the drive motor 7 and a transmission synchronous pulley 9 rotatably mounted on the mounting base 6. The drive synchronous pulley 8 and the transmission synchronous pulley 9 are mounted on the same matching synchronous belt 10. The adjustable grinding head includes a cup-shaped wire brush 17. The bottom of the cup-shaped wire brush 17 is connected to a cup-shaped wire brush mounting base 16. The bottom of the cup-shaped wire brush mounting base 16 is connected to a drive shaft 15 through a spherical joint. The drive shaft 15 is coaxially and fixedly connected to the transmission synchronous pulley 9.

[0017] It should be noted that when grinding and removing rust from the end cover 1 of the axle box, the first surface 2, the second surface 3, and the third surface 4 need to be ground in sequence. The third surface 4 is irregular and has a certain downward curvature.

[0018] In the above scheme, when grinding the third surface 4 of the axle box end cover 1, the drive motor 7 is started. The drive motor 7 drives the drive synchronous pulley 8 to rotate through its output shaft. The drive synchronous pulley 8 rotates and drives the transmission synchronous pulley 9 to rotate synchronously through the synchronous belt 10. The rotation of the transmission synchronous pulley 9 drives the cup-shaped wire brush 17 to rotate, grinding and removing rust from the axle box end cover 1. When grinding some bent, deformed, irregular, or space-restricted areas, the spherical joint is connected to the transmission shaft 15, so that the cup-shaped wire brush 17 can fit into the bent or deformed areas or reach into the irregular or space-restricted areas to grind them. This improves the grinding efficiency and grinding effect, eliminates the need for workers to use an angle grinder, reduces the labor intensity of workers, and avoids the harm to workers' bodies caused by dust.

[0019] See some possible implementations. Figure 2As shown, the mounting base 6 is an L-shaped mounting plate, which includes a long arm and a short arm connecting the long arm. The short arm is set vertically downward. The drive motor 7 is fixedly mounted on the short arm, and the transmission synchronous pulley 9 is rotatably mounted on the long arm, so that the drive synchronous pulley 8 and the transmission synchronous pulley 9 are at the same horizontal position.

[0020] See some possible implementations. Figure 2 As shown, the railway passenger car wheel axle box end cover grinding equipment provided in this application embodiment also includes a lifting cylinder 11. The output end of the lifting cylinder 11 is fixedly connected to the bottom of the long arm through a mounting component. The mounting component includes a frame 5, which has a lower support beam and an upper support beam. The bottom of the lifting cylinder 11 is mounted on the lower support beam through a tailstock 12. A lifting guide sleeve 13 is vertically mounted on the bottom of the upper support beam. A lifting guide column 14 is coaxially fixedly connected to the output end of the lifting cylinder 11. The lifting guide column 14 is slidably disposed in the lifting guide sleeve 13, and the upper end of the lifting guide column 14 is fixedly connected to the bottom of the long arm. The lifting guide sleeve 13 is used to support and position the lifting guide column 14 and the output shaft of the lifting cylinder 11 to prevent them from tilting due to force.

[0021] In the above scheme, during the grinding process of the axle box end cover 1, it is necessary to adjust the vertical position of the cup-shaped wire brush 17 at the same time. At this time, the lifting cylinder 11 is started. The lifting cylinder 11 drives the lifting guide column 14 to slide up and down through its output end, which in turn drives the cup-shaped wire brush 17 to slide up and down, so that the cup-shaped wire brush 17 can grind and remove rust from each grinding surface of the axle box end cover 1.

[0022] See some possible implementations. Figure 2 and Figure 3 As shown, a brush arm 18 is fitted around the synchronous belt 10. The brush arm 18 is fixed on the long arm and is used to protect the synchronous belt 10, the drive synchronous pulley 8 and the transmission synchronous pulley 9.
