Description

Technical Field

[0001] The utility model relates to the technical field of train wheel grinding, in particular to a grinding device for repairing EMU wheels. Background Technique

[0002] Train wheels are an important part of a train. When the train wheels are damaged, a grinding device is needed to grind the damaged part before repair.

[0003] The existing Chinese patent with the application number 202221500339.4 discloses a wheel grinding device for repairing train wheel wear, belonging to the technical field of train wheel grinding. The key points of its technical solution include a bottom plate. A support frame is arranged on the front side of the top of the bottom plate. By setting a grinding mechanism, starting the motor, the output end of the motor drives the connecting rod to rotate. While the connecting rod rotates, it drives the grinding roller to rotate, thus playing a role in grinding the train wheel. By setting a first cylinder, starting the first cylinder, the telescopic end of the first cylinder drives the connecting rod to move. When the connecting plate moves, it drives the slider at the bottom of the support frame and the support plate to move inside the chute. When moving to the contact between the train wheel and the grinding roller, by setting a second cylinder, starting the second cylinder, the telescopic end of the second cylinder drives the U-shaped plate to rise, and the height of the U-shaped plate is increased, so as to place train wheels of different sizes, thus facilitating the use.

[0004] However, this wheel grinding device for repairing train wheel wear still has some deficiencies in actual use. For example, the repair range is limited, and it can only repair the side of the wheel, and the front and back sides cannot be directly repaired, resulting in poor repair effects.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1-4 shown, the present utility model provides a technical solution: including a main body component 1, a rotating component 2 is fixedly installed at the inner bottom of the main body component 1, and a firmware component 3 is fixedly installed on the front surface of the rotating component 2;

[0024] The rotating component 2 includes two baffles 201, a rotating shaft 202 is rotatably installed between the opposite surfaces of the two baffles 201, an installation rotating plate 203 is fixedly sleeved on one side of the shaft body of the rotating shaft 202, a side plate 204 is fixedly installed at the top of the outer side of the baffle 201 arranged on one side, a servo motor 205 is fixedly installed on the top surface of the side plate 204, a worm 207 is fixedly installed at the bottom end of the output shaft of the servo motor 205, a worm gear 206 is fixedly sleeved on one end of the rotating shaft 202, and one side of the worm gear 206 is meshed with the rod body of the worm 207;

[0025] The firmware component 3 includes a third linear motor 301. On one side of the front of the slider of the third linear motor 301, an L-shaped moving plate 302 is fixedly installed. On the other side of the front of the horizontal part of the L-shaped moving plate 302, a second rotating motor 305 is fixedly installed. One end of the output shaft of the second rotating motor 305 is fixedly installed with a fixed rod 306;

[0026] The two baffles 201 are respectively fixedly installed on both sides of the top surface of the bottom plate 101. The third linear motor 301 is fixedly installed at the edge of one side of the front of the installation rotating plate 203.

[0027] In this embodiment, the main body component 1 includes a bottom plate 101. On the back of the bottom plate 101, a first linear motor 102 is provided. On the top surface of the slider of the first linear motor 102, a main rod 103 is fixedly installed. At the top of the front of the main rod 103, a top plate 104 is fixedly installed. On one side of the top plate 104, a second linear motor 105 is provided. On one side of the slider of the second linear motor 105, a cylinder 106 is fixedly installed. At the bottom end of the piston rod of the cylinder 106, a first rotating motor 107 is fixedly installed. At the bottom end of the output shaft of the first rotating motor 107, a grinding wheel 108 is fixedly installed. The grinding wheel 108 can be controlled by the first linear motor 102 to move to the required grinding position. Then, the cylinder 106 drives the grinding wheel 108 to descend and contact the surface of the train wheel 308. After contact, the first rotating motor 107 is started, and the grinding wheel 108 is driven by the first rotating motor 107 to rotate to grind the side surface of the train wheel 308.

[0028] A backing plate 307 is fixedly sleeved on the rod body of the fixed rod 306 near one end of the second rotating motor 305. A train wheel 308 is movably sleeved on the rod body of the fixed rod 306. A threaded washer 309 is threadedly installed at one end of the fixed rod 306 away from the second rotating motor 305, which can prevent the rear train wheel 308 from rubbing against other components when rotating.

[0029] A tightening screw 303 is threadedly inserted into one side of the front of the horizontal part of the L-shaped moving plate 302. A ball 304 is rotatably embedded at one end of the tightening screw 303. By manually rotating the tightening screw 303, the ball 304 provided at one end of the tightening screw 303 can be made to abut against the front of the train wheel 308, thereby restricting the longitudinal movement of the train wheel 308.

[0030] During use, the L-shaped moving plate 302 is controlled to move by the third linear motor 301, so that the threaded washer 309 can be disconnected from the front surface of the mounting rotating plate 203. After the disconnection, when a certain interval is left between the threaded washer 309 and the mounting rotating plate 203, the threaded washer 309 is manually unscrewed. Subsequently, the train wheel 308 is slidably sleeved on the fixed rod 306. After being sleeved, the threaded washer 309 is manually screwed on to prevent the train wheel 308 from slipping off the rod body of the fixed rod 306. Also, the tightening screw rod 303 needs to be manually rotated. Rotating the tightening screw rod 303 can make the ball 304 provided at one end of the tightening screw rod 303 abut against the front surface of the train wheel 308, thereby restricting the longitudinal movement of the train wheel 308. Subsequently, the grinding wheel 108 can be controlled by the first linear motor 102 to move to the required grinding position. Then, the grinding wheel 108 is driven by the cylinder 106 to descend and contact the side surface of the train wheel 308. After the contact, the first rotating motor 107 is started, and the grinding wheel 108 is driven by the first rotating motor 107 to rotate to grind the side surface of the train wheel 308. In order to comprehensively grind the side surface of the train wheel 308, the train wheel 308 can be driven to rotate by the second rotating motor 305, so as to comprehensively grind the side surface of the train wheel 308.

[0031] Meanwhile, when it is necessary to grind the front and back surfaces of the train wheel 308, the train wheel 308 is conveniently rotated through the rotating assembly 2. Specifically, the servo motor 205 is started. Under the action of the servo motor 205, the worm 207 drives the worm gear 206 to rotate. The rotation of the worm gear 206 drives the rotating shaft 202 to rotate. By the rotation of the rotating shaft 202, the fixing component 3 can be driven to rotate, so that the front and back surfaces of the train wheel 308 can be conveniently adjusted to face upward, and thus the front and back surfaces of the train wheel 308 can be comprehensively repaired and ground by the grinding wheel 108.

[0032] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
