Description

Technical Field

[0001] This utility model relates to the field of automated production technology, and more specifically, to a CNC planar drilling machine for processing steel rails that is easy to load. Background Technology

[0002] A CNC planar drilling machine for rail processing is a specialized piece of equipment used for rail machining. Based on CNC technology, it can precisely control the drill bit to perform drilling and other machining operations on the rail plane. It features a high degree of automation, high machining accuracy, and high efficiency. According to a pre-set program, it can accurately complete drilling tasks of different specifications and locations, effectively improving rail machining quality and production efficiency. It is widely used in railway construction and related rail processing fields.

[0003] Publication No. (CN219829507U) discloses an automatic rail feeding device, including several storage racks, several swaying racks, and a feeding mechanism. The storage racks are arranged parallel to each other on one side of the heating furnace along the conveying direction of the rail components to be processed, and are connected by a connecting shaft. The area between the storage racks forms a storage area and a feeding area. The storage area is used to store the rail components to be processed, and the feeding area is used to feed the rail components to be processed into the storage area. Several swaying racks are arranged at intervals between the storage racks, in the same direction as the storage racks. The area between the swaying racks forms a swaying area for placing several rail components to be processed. Pushing mechanisms are respectively provided on the swaying racks and the storage racks, and the pushing mechanism on the swaying rack is mounted on the swaying rack via a pushing drive mechanism. This embodiment of the invention can realize a complete feeding operation of continuous production storage, swaying, preparation, and feeding.

[0004] However, this automatic rail feeding device has the following drawbacks: it cannot adapt to rails of different widths. When it is necessary to process rails of different widths, because the device cannot automatically adapt, the operator has to frequently stop the machine to adjust the equipment, and may even need to replace specific parts to adapt to different rails. This will undoubtedly consume a lot of time, cause production process interruption, seriously reduce production efficiency, and increase the production time and cost per unit product. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a CNC planar drilling machine for steel rail processing that is easy to load, so as to solve the problem that the prior art cannot adapt to steel rails of different widths.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a CNC planar drilling machine for rail processing that facilitates material loading, comprising...

[0007] Two bases are provided, and a drill press is fixedly connected to the outside of each base. Multiple motors are fixedly connected to the outside of each drill press. A rotating column is fixedly connected to the drive end of each motor. A drive wheel is fixedly connected to the outside of each rotating column. Multiple rubber strips are fixedly connected to the outside of each drive wheel. Multiple support wheels are rotatably connected to the inner wall of the drill press. Two sliding grooves are formed in the inner wall of the drill press. A drill bit is fixedly connected to the outside of each base. An adjustment assembly for adjusting subsequent components is movably connected to the inner wall of the drill press.

[0008] The adjustment assembly includes multiple connecting columns, which are externally movably connected to the inner wall of the drill press. Limiting wheels are rotatably connected to the outside of each connecting column. A clamping plate is fixedly connected to the outside of each connecting column. Multiple clamping slots are provided on the outside of the drill press. A pressure plate is slidably connected to the inner wall of the drill press. A top block is fixedly connected to the outside of the pressure plate. Two springs are fixedly connected to the end of the pressure plate away from the top block.

[0009] The end of the spring away from the pressure plate is fixedly connected to the inner wall of the drill press, and the outer side of the top block is slidably connected to the inner wall of the drill press.

[0010] The rotating column is rotatably connected to the inner wall of the drill press, and the two ends of the support wheel are in contact with the outside of the slide groove.

[0011] The end of the top block away from the pressure plate is in contact with the outside of the card plate, and the end of the card plate away from the top block is movably connected to the inner wall of the card slot.

[0012] The outer side of the rotating column is in contact with the outer side of the sliding groove, and the outer side of the connecting column is in contact with the outer side of the sliding groove.

[0013] When the plate moves upward, the spring is compressed; when the plate moves downward, the spring is extended.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In the above scheme, by starting the motor, the motor drives the rail to move inside the chute through the drive wheel. The rubber strip increases the friction between the rail and the rail, making the rail move stably in the chute. Then, the drill bit drills holes in the rail. At the same time, the rail rotates outside the support wheel, and the support wheel rotates with the movement of the rail, avoiding excessive movement of the rail. The drill bit can drill holes according to the position of the rail, realizing automatic feeding and saving labor costs.

[0016] In the above solution, by setting an adjustment component, the clamping plate is moved by lifting. At the same time, the clamping plate moves through the connecting column and drives the limit wheel, achieving positioning according to the "I" shape of the rail. It also adapts to rails of different widths. When the clamping plate is lifted, the clamping plate compresses the spring through the top block, and the spring contracts to satisfy the movement adjustment of the clamping plate. When the clamping plate is released, the spring extends, so that the top block is pressed tightly against the outside of the clamping plate, locking the clamping plate and preventing displacement. This improves work efficiency and adapts to rails of different widths through adjustment. Attached Figure Description

[0022] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0023] As attached Figure 1 To be continued Figure 3 An embodiment of this utility model provides a CNC planar drilling machine for rail processing that facilitates material loading, including...

[0024] Two bases 1 are fixedly connected to the external parts of the two bases 1. The bases 1 ensure that the drilling machine does not shake during operation, thus ensuring drilling accuracy; while the drilling machine 2 is the main body of the entire processing equipment, supporting the normal operation of all components. Multiple motors 3 are fixedly connected to the external parts of the drilling machine 2. The motors 3 serve as power sources, providing power for the movement of the rails in the drilling machine 2. The drive ends of the multiple motors 3 are fixedly connected to rotating columns 4. After the motors 3 start, their drive ends drive the rotating columns 4 to rotate, and the rotation of the rotating columns 4 transmits power. Drive wheels 5 are fixedly connected to the external parts of the rotating columns 4. When the rotating columns 4 rotate, they drive the drive wheels 5 to rotate, and the rotation of the drive wheels 5 is the direct power source for the movement of the rails. Multiple rubber strips 6 are fixedly connected to the external parts of the drive wheels 5. The presence of the rubber strips 6 increases the friction between the drive wheels 5 and the rails, allowing the rails to move stably in the slide grooves 8 under the drive of the drive wheels 5, avoiding slippage.

[0025] Multiple support wheels 7 are rotatably connected to the inner wall of the drilling machine 2. These support wheels 7 provide support and assist rotation during the movement of the rail. When the rail moves under the drive wheel 5, it rotates outside the support wheels 7, and the support wheels 7 rotate with the rail, preventing excessive movement and ensuring the stability of the rail's movement. Two sliding grooves 8 are formed on the inner wall of the drilling machine 2. These grooves provide a specific track for the rail's movement, allowing it to move along a predetermined route and ensuring the accuracy of the drilling position. A drill bit 9 is fixedly connected to the outside of the base 1. The drill bit 9 is a key component for drilling holes in the rail. When the rail moves to the appropriate position, the drill bit 9 performs drilling operations according to the rail's position, thus processing the rail.

[0026] The adjustment assembly includes multiple connecting columns 10, which are externally and movably connected to the inner wall of the drilling machine 2. The connecting columns 10 serve to connect and transmit motion, transmitting the movement of the chuck 12 to the limiting wheel 11, thus adjusting the position of the limiting wheel 11. The limiting wheel 11 is rotatably connected to the external side of the connecting column 10. The limiting wheel 11 is positioned according to the "I" shape of the rail and can adapt to rails of different widths. Adjusting its position better limits and guides the rail. A chuck 12 is fixedly connected to the external side of the connecting column 10. The chuck 12 is the operating component of the adjustment assembly. Lifting the chuck 12 moves the connecting column 10 and the limiting wheel 11, thereby adjusting the rail positioning. Multiple slots 13 are provided on the external side of the drilling machine 2. These slots 13 are used to lock the chuck 12. When the chuck 12 moves to the appropriate position, it engages with the slot 13, ensuring the stability of the chuck 12 and preventing displacement. A pressure plate 14 is slidably connected to the inner wall of the drilling machine 2. The pressure plate 14 plays an auxiliary role in the movement of the chuck 12. It cooperates with the top block 15 and the spring 16 to adjust and lock the chuck 12. The top block 15 is fixedly connected to the outside of the pressure plate 14. When the chuck 12 moves, the top block 15 contacts the chuck 12. By squeezing and releasing the spring 16, the spring 16 is compressed and extended, thereby cooperating with the movement and locking of the chuck 12. Two springs 16 are fixedly connected to the end of the pressure plate 14 away from the top block 15. The springs 16 are the components for adjusting and locking the chuck 12. When the chuck 12 is pulled up, the springs 16 are compressed to provide space for the movement of the chuck 12; when the chuck 12 is released, the springs 16 extend, so that the top block 15 is pressed tightly against the chuck 12, thereby locking the chuck 12.

[0027] The end of the spring 16 away from the pressure plate 14 is fixedly connected to the inner wall of the drill press 2, and the outer side of the top block 15 is slidably connected to the inner wall of the drill press 2. The fixed end of the spring 16 to the inner wall of the drill press 2 ensures the stability of the spring 16 during the extension and retraction process; the sliding of the top block 15 on the inner wall of the drill press 2 allows it to accurately contact the clamping plate 12, thereby realizing the adjustment and locking of the clamping plate 12.

[0028] The rotating column 4 is externally rotatably connected to the inner wall of the drill press 2, and the two ends of the support wheel 7 are in contact with the outside of the slide groove 8. The rotating column 4 rotates on the inner wall of the drill press 2, ensuring its rotational stability, thereby stably driving the drive wheel 5 to rotate; the two ends of the support wheel 7 are in contact with the outside of the slide groove 8, enabling the support wheel 7 to better support and guide the rail, ensuring the stable movement of the rail in the slide groove 8.

[0029] The end of the top block 15 away from the pressure plate 14 is in contact with the outside of the locking plate 12, and the end of the locking plate 12 away from the top block 15 is movably connected to the inner wall of the locking groove 13. The contact between the top block 15 and the locking plate 12 allows the spring 16 to be compressed when the locking plate 12 moves; the locking plate 12 is movably connected to the locking groove 13, and when the locking plate 12 moves to the appropriate position, it is locked into the locking groove 13.

[0030] The outer surface of the rotating column 4 contacts the outer surface of the slide groove 8, and the outer surface of the connecting column 10 contacts the outer surface of the slide groove 8. The contact between the rotating column 4 and the slide groove 8 ensures that the drive wheel 5 can accurately drive the rail to move in the slide groove 8; the contact between the connecting column 10 and the slide groove 8 allows the limiting wheel 11 to better limit and guide the rail, ensuring the positional accuracy of the rail during movement.

[0031] When the clamping plate 12 moves upward, the spring 16 is compressed; when the clamping plate 12 moves downward, the spring 16 is extended. When the clamping plate 12 is pulled upward, the clamping plate 12 compresses the spring 16 through the top block 15, causing the spring 16 to contract and providing space for the movement of the clamping plate 12. When the clamping plate 12 is released and moves downward, the spring 16 extends, causing the top block 15 to press tightly against the clamping plate 12, thereby locking the clamping plate 12 and preventing it from shifting.

[0032] The working process of this utility model is as follows:

[0033] First, the motor 3 is started. The motor 3 drives the rail to move inside the slide 8 through the drive wheel 5. The rubber strip 6 increases the friction between the rail and the rail, making the rail move stably in the slide 8. Then, the drill bit 9 drills holes in the rail. At the same time, the rail rotates outside the support wheel 7. The support wheel 7 rotates with the movement of the rail, avoiding excessive movement of the rail. Meanwhile, the drill bit 9 can drill holes according to the position of the rail, realizing automatic feeding and saving labor costs.

[0034] The clamping plate 12 is moved by lifting, and at the same time, the clamping plate 12 drives the limiting wheel 11 to move through the connecting column 10, realizing the positioning according to the "I" shape of the rail. At the same time, it adapts to rails of different widths. When the clamping plate 12 is lifted, the clamping plate 12 will squeeze the spring 16 through the top block 15. The spring 16 will contract to meet the movement adjustment of the clamping plate 12. At the same time, when the clamping plate 12 is released, the spring 16 will extend, so that the top block 15 is pressed tightly against the outside of the clamping plate 12, thereby locking the clamping plate 12 and preventing the clamping plate 12 from shifting. This improves work efficiency and adapts to rails of different widths through adjustment.
