Description

Technical Field

[0001] This utility model relates to the field of CNC non-dismounting wheel lathes, and in particular to a swing drive device for a CNC non-dismounting wheel lathe. Background Technology

[0002] The wheel lathe is an important piece of equipment in railway vehicle maintenance. It is mainly used to cut and repair the wheel tread and flange without disassembling the wheelset. Typically, the wheel lathe's lifting mechanism suspends the two axle ends of the wheel to be repaired off the rail. The machine tool's motor drives the wheelset to rotate via a transmission structure, while the machine tool's cutting tools machine the wheel flange tread according to instructions from the CNC system.

[0003] In practical use, the wear degree of the wheel tread is different. It is especially important to align the axis of the wheel with the tool during the wheel loading process. In addition, sufficient driving force needs to be maintained at all times during the wheel processing. Misalignment of the axis will accelerate the wear of the tool during processing, and insufficient driving force will wear the drive roller. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art, the present invention provides a swing drive device for a CNC non-drop wheel lathe, which can be achieved by the swing of the swing seat through the piston rod of the drive cylinder, so that the drive wheel of the drive wheel arm can maintain a relatively close state when the wheel is being processed.

[0007] As an optional implementation, a support base is provided on the base, and the cylinder body of the drive cylinder is hinged to the support base.

[0008] As an optional implementation, a support plate is provided on both sides of the connecting seat, and the support plate is inclinedly connected to the swing seat; the support plates on both sides of the connecting seat are inclined in opposite directions.

[0024] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0025] See Figures 1-4 This utility model discloses a swing drive device for a CNC non-dismounting wheel lathe, including a machine base 10 and a drive wheel assembly. The drive wheel assembly includes a swing seat 30, a swing drive component, a drive wheel arm 50, a drive wheel 60, and a rotation drive component. The swing seat 30 is rotatably connected to the machine base 10 via a swing shaft 34, so that the swing seat 30 can swing up and down around the swing shaft 34. Specifically, the swing drive component includes a drive cylinder 20, the cylinder body of which is mounted on the machine base 10, and the piston rod 212 of the drive cylinder is connected to the swing seat 30. The extension or retraction of the piston rod 212 of the drive cylinder can drive the swing seat 30 to swing.

[0026] In addition, the drive wheel arm 50 is rotatably mounted on the swing seat 30. One end of the drive wheel arm 50 is connected to the rotation drive component, and the other end of the drive wheel arm 50 is connected to the drive wheel 60. The rotation drive component is mounted on the swing seat 30 and is used to drive the drive wheel arm 50 to rotate.

[0027] It should be noted that the aforementioned drive cylinder 20 can be selected as a drive oil cylinder or drive air cylinder in related technologies.

[0028] Based on the above structure, when using the swing drive device of the CNC non-falling wheel lathe of this utility model to perform wheel maintenance, the wheel can be lifted off the track by the lifting mechanism of the non-falling wheel lathe. Then, the swing drive is activated, and the piston rod 212 of the drive cylinder of the swing drive extends, so that the swing seat 30 can swing upward around the swing axis 34. At this time, after the swing seat 30 moves upward, the drive wheel arm 50 and the drive wheel 60 on the swing seat 30 can both come into contact with the wheel surface of the wheel. Then, the drive is rotated to drive the drive wheel arm 50 to rotate, and the drive wheel arm 50 can drive the drive wheel 60 to rotate. The rotating drive wheel 60 comes into contact with the wheel surface of the wheel through friction, thereby realizing the grinding and maintenance of the wheel.

[0029] It is important to emphasize that, during the wheel grinding process, the driving force for the drive wheel 60 to contact the wheel surface is provided by the piston rod 212 of the drive cylinder. The drive cylinder 20 maintains continuous and uniform pressure on the drive wheel 60 using hydraulic or pneumatic pressure, and can replenish fluid at any time to supplement pressure. This allows the wheel to maintain a stable driving force as the drive wheel 60 rotates, reducing the possibility of jamming due to insufficient driving force. On the other hand, since the piston rod 212 of the drive cylinder is driven by hydraulic or pneumatic pressure, it can also adaptively float according to the friction force exerted on the drive wheel 60 during the grinding process, reducing the impact of the wheel on the drive wheel 60.

[0030] As an optional implementation, the swing drive component may also include a connecting shaft 211, and the swing seat 30 may be provided with a connecting seat 31, which has a through-hole. The piston rod 212 of the drive cylinder passes through the through-hole and is rotatably connected to the connecting seat 31 via the connecting shaft 211. In this way, the swing seat 30 and the piston rod 212 of the drive cylinder are rotatably connected via the through-hole of the connecting shaft 211 and the connecting seat 31. Therefore, the connection point between the piston rod 212 of the drive cylinder and the swing seat 30 is a movable point. When the piston rod 212 of the drive cylinder moves upward to the point where the drive wheel 60 is in contact with the wheel, the drive wheel 60 may float due to friction and impact with the wheel. The connection point of the piston rod can move adaptively to prevent breakage due to rigid connection.

[0031] As an optional implementation, a support base 14 can also be provided on the base 10, and the cylinder body of the drive cylinder 20 is hinged to the support base 14. In this way, the cylinder body of the drive cylinder 20 can also be hinged to the support base 14, which can adapt to the swing of the swing seat 30 and move accordingly, reducing the jamming during the drive process.

[0032] As an optional implementation, the connecting seat 31 is provided with support plates 311 on both sides, and the support plates 311 are inclined to the swing seat 30. The support plates 311 on both sides of the connecting seat 31 are inclined in opposite directions. In this way, the connecting seat 31 can be connected to the swing seat 30 through the inclined support plates 311 on both sides to form a trapezoidal connection point, and the resulting assembly structure is more stable.

[0033] As an optional implementation, a touch unit can be provided on the swing seat 30, and a touch switch 12 can be provided on the base 10. The touch unit can touch the touch switch 12 during the swing of the swing seat 30. Since the grinding action needs to start after the swing seat 30 swings to the point where the drive wheel 60 contacts the wheel surface, the touch unit can touch the touch switch 12. After the touch switch 12 is touched, it indicates that the swing of the swing seat 30 has reached the swing position and sends a stop signal to the drive cylinder 20 to control the drive cylinder 20 to stop driving.

[0034] As an optional implementation, a mounting base 13 is provided on the base 10, and the touch switch 12 is mounted on the top of the mounting base 13. After the touch switch 12 is assembled to the top of the mounting base 13, the touch switch 12 has a certain height on the base 10, which can better adapt to the touch height of the touch part of the swing seat 30.

[0035] As an optional implementation, multiple mounting grooves 35 can be provided on the swing seat 30; touch blocks 32 are mounted on the mounting grooves 35, and the mounting heights of the touch blocks 32 in two adjacent mounting grooves 35 are different; the touch unit includes touch blocks 32. Since the swing seat 30 needs to swing to different heights for different wheels, the touch switch 12 can be touched by touch blocks 32 at different heights in different mounting grooves 35, and touch can be performed for different swing heights.

[0036] As an optional implementation, in order to facilitate the assembly of the swing seat 30 and the base 10, rotating seats can be provided on both sides of the base 10. The shaft end of the swing shaft 34 is rotatably connected to the rotating seat through a bearing. An assembly space for the swing seat 30 can be formed between the rotating seats on both sides. The shaft end of the swing shaft 34 of the swing seat 30 is respectively assembled to the rotating seats on both sides. After assembly, the swing of the swing seat 30 is between the two rotating seats, reducing interference during the swing process.

[0037] As an optional implementation, at least two sets of drive wheel arms 50, drive wheels 60, and rotational drive components are provided. Specifically, the swing seat 30 is provided with at least two connecting arms 33, each with a through-channel. At least two sets of drive wheel arms 50 are rotatably connected to the through-channels. One end of each of the at least two sets of drive wheel arms 50 is connected to at least two sets of rotational drive components, and one end of each of the at least two sets of drive wheel arms 50 is connected to at least two sets of drive wheels 60. Thus, at least two sets of drive wheels 60 are provided on the swing seat 30, and each of the at least two sets of drive wheels 60 has a separate rotational drive component to rotate and drive a separate drive wheel arm 50, so that the at least two sets of drive wheels 60 can grind the at least two sets of wheels simultaneously or individually, depending on the actual needs.

[0038] Of course, drive cylinders can also be installed on both sides of the swing seat 30 to swing on both sides of the swing seat 30, so that the driving force on the swing seat 30 is stable.

[0039] As an optional implementation, the rotation drive in this embodiment includes a drive motor 40 and a transmission structure. The shaft of the drive motor 40 is connected to the drive wheel arm 50 through the transmission structure. Specifically, the transmission can be a gear transmission structure. Therefore, the rotation of the shaft of the drive motor 40 can be transmitted to the drive wheel arm 50 through the gear transmission structure. This makes the rotation speed of the drive wheel arm 50 stable, and thus the rotation speed of the drive wheel 60 stable.

[0040] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
