Description

Technical Field

[0001] This utility model relates to the technical field of H-beam steel component processing, specifically an automatic chip removal drilling device for H-beam steel components. Background Technology

[0002] H-beams are widely used in steel structures such as bridges, factories, and building frames, and are typically connected using high-strength bolts. Drilling is one of the key processes in the fabrication of H-beams, and its purpose is to facilitate the installation and fixing of connectors such as high-strength bolts, ordinary bolts, and semi-circular head rivets, thereby ensuring the overall stability and load-bearing capacity of the steel structure.

[0003] When drilling existing H-beam steel components, twist drills are typically used to remove chips. Twist drills, due to their spiral groove design, can effectively remove chips, ensuring a smooth drilling process. However, the chips, after rising a certain height along the thread grooves and exiting the hole, fall back onto the workpiece surface under gravity, causing chip accumulation near the hole and hindering subsequent drilling. This increases drilling resistance and affects the processing efficiency of drilling H-beam steel components. Utility Model Content

[0004] The purpose of this invention is to provide an automatic chip removal drilling device for H-shaped steel components to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic chip removal drilling device for H-beam steel components includes a circulating cooling device, an electrical control device, and a drilling device. The drilling device includes a drill press and a support frame fixedly mounted on the drill press. A lifting plate is slidably disposed on the support frame, and a drilling assembly is mounted on the lifting plate.

[0007] A reciprocating cutting component is mounted on the lifting plate, arranged along the axial direction of the drilling assembly, and connected to the drilling assembly;

[0008] A chip removal mechanism is arranged along the axial direction of the drilling assembly and connected to the lifting plate. The chip removal mechanism includes a chip collection cylinder fixed to the lifting plate and a pusher rotatably arranged on the chip collection cylinder. The reciprocating cutting member cuts off the waste chips after drilling and rising from the drilling assembly. The pusher can push the waste chips that fall onto the surface of the chip collection cylinder.

[0009] The H-beam steel component drilling equipment with automatic chip removal as described above: the drilling assembly includes a drill shank rotatably mounted on the lifting plate, the drill shank being fixed to an output shaft formed by a motor fixedly mounted on the lifting plate, and a drill bit being fixedly mounted at one end of the drill shank away from the output shaft.

[0010] The H-beam steel component drilling equipment with automatic chip removal as described above: the reciprocating cutting component includes a drive cylinder arranged along the axial direction of the drill shank, and a sliding groove is formed on the outer wall of the drive cylinder;

[0011] It also includes a limiting cylinder arranged along the axial direction of the drill shank and fixed to the lifting plate. A movable tube is slidably arranged at one end of the limiting cylinder away from the lifting plate, and a ball bearing that is adapted to slide along the groove is rolled on the inner wall of the movable tube. A cutting blade with an annular structure is formed at the end of the movable tube.

[0012] The H-beam steel component drilling equipment with automatic chip removal as described above: the chip collection cylinder has multiple through slots along its circumference, and the through slots are connected to the cavity formed inside the chip collection cylinder.

[0013] The H-beam steel component drilling equipment with automatic chip removal as described above: the pushing component includes a collar rotatably mounted on the chip collection cylinder, the collar having a plurality of push plates arranged along the circumference that can abut against the end of the chip collection cylinder, and the collar being connected to the output shaft via a transmission assembly.

[0014] The H-beam steel component drilling equipment with automatic chip removal as described above: the transmission assembly includes a transmission shaft rotatably mounted on the lifting plate, one end of the transmission shaft is connected to the collar through a gear set, and the other end is connected to the output shaft through a toothed belt.

[0015] The H-beam steel component drilling equipment with automatic chip removal as described above: the chip collection cylinder is arranged with a conical surface structure near the inner ring of the drill bit.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] By controlling the lifting plate to descend towards the steel component while simultaneously driving the drilling assembly to rotate, the drilling chips rise in a tornado-like motion in the opposite direction of the drilling assembly's rotation. As the drilling assembly performs its drilling action, it also drives the reciprocating cutting component to move back and forth along the axis of the drilling assembly. This allows the reciprocating cutting component to cut the rising chips, which then fall onto the surface of the chip collection cylinder under the influence of gravity and centrifugal force. At this point, the pushing component rotates relative to the chip collection cylinder and pushes the chips onto its surface, ensuring they are collected uniformly. This reduces interference from chips on the drilling path and improves drilling stability and efficiency. Furthermore, this design allows the drill bit to maintain a good working condition during drilling, avoiding the problems of chips flying or accumulating in the working area that occur in traditional drilling processes.

[0025] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0026] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0027] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0028] Please see Figures 1-6In this embodiment of the present invention, an automatic chip removal drilling device for H-beam steel components includes a circulating cooling device, an electrical control device, and a drilling device. The drilling device includes a drill press 1 and a support frame 3 fixedly mounted on the drill press 1. A lifting plate 4 is slidably disposed on the support frame 3, and a drilling assembly is mounted on the lifting plate 4.

[0029] A reciprocating cutting component is installed on the lifting plate 4, arranged along the axial direction of the drilling assembly and connected to the drilling assembly;

[0030] A chip removal mechanism is arranged along the axial direction of the drilling assembly and connected to the lifting plate 4. The chip removal mechanism includes a chip collection cylinder 10 fixed to the lifting plate 4 and a pusher rotatably arranged on the chip collection cylinder 10. The reciprocating cutting member cuts off the waste chips after drilling and rising from the drilling assembly. The pusher can push the waste chips that fall onto the surface of the chip collection cylinder 10.

[0031] It should be noted that a mounting platform 2 is fixedly installed on the drilling machine 1 to support the steel components, making it easier for the drilling assembly to drill holes in the steel components.

[0032] In this embodiment, when the drilling assembly drills a hole in the steel component, the lifting plate 4 is controlled to descend towards the steel component while simultaneously driving the drilling assembly to rotate. This causes the drilled chips to rise in a tornado-like motion in the opposite direction of the drilling assembly's rotation. Simultaneously, the drilling assembly performs the drilling action, driving the reciprocating cutting component to move back and forth along the axis of the drilling assembly. This allows the reciprocating cutting component to cut the rising chips, which then fall onto the surface of the chip collection cylinder 10 under the influence of gravity and centrifugal force. At this point, the pushing component rotates relative to the chip collection cylinder 10 and pushes the chips onto its surface, ensuring they are collected uniformly. This reduces interference from the chips on the drilling path and improves drilling stability and efficiency. Furthermore, this design allows the drilling assembly to maintain a good working condition during drilling, avoiding the problems of chips flying or accumulating in the working area during traditional drilling processes.

[0033] For further solutions to this utility model, please refer to [link / reference]. Figure 2 The drilling assembly includes a drill shank 13 rotatably mounted on the lifting plate 4. The drill shank 13 is fixed to the output shaft of the motor 5 fixedly mounted on the lifting plate 4, and a drill bit 12 is fixedly mounted at one end of the drill shank 13 away from the output shaft.

[0034] The reciprocating cutting component includes a drive cylinder 16 arranged axially along the drill shank 13, and a groove 1601 is formed on the outer wall of the drive cylinder 16;

[0035] It also includes a limiting cylinder 15 that is axially arranged along the drill shank 13 and fixed to the lifting plate 4. A movable tube 14 is slidably arranged at one end of the limiting cylinder 15 away from the lifting plate 4, and a ball bearing 1402 that is slidably adapted to the slide groove 1601 is rolled on the inner wall of the movable tube 14. A cutting blade 1401 with an annular structure is formed at the end of the movable tube 14.

[0036] Preferably, at least one set of strip grooves 1501 are formed on the inner wall of the limiting cylinder 15, and a strip block 1403 is provided on the outer wall of the movable tube 14 to slide in cooperation with the strip grooves 1501. Under the limiting effect of the strip grooves 1501 and the strip block 1403, the movable tube 14 and the limiting cylinder 15 are slidably connected, so that when the driving cylinder 16 squeezes the movable tube 14, the movable tube 14 can reciprocate up and down along the axial direction of the driving cylinder 16.

[0037] Specifically, when the drill shank 13 rotates under the drive of the output shaft of the motor 5, it can drive the limiting cylinder 15 to rotate synchronously. At this time, the sliding groove 1601 on the drive cylinder 16 generates an inclined force on the ball 1402, so that the movable tube 14 moves linearly along the axis of the drive cylinder 16 while the drive cylinder 16 rotates. When the drive cylinder 16 rotates once, the movable tube 14 completes a set of lifting and lowering actions. When the movable tube 14 descends, the cutting blade 1401 can cut the rising and swirling waste chips, so that the waste chips can fall into the chip collection cylinder 10 under the action of gravity, thereby realizing the collection of waste chips and preventing waste chips from falling onto the surface of the H-shaped steel component and affecting the drilling work.

[0038] Preferably, the chip collection cylinder 10 has a plurality of through grooves 1001 along its circumference, and the through grooves 1001 communicate with the cavity formed inside the chip collection cylinder 10.

[0039] For further solutions to this utility model, please refer to [link / reference]. Figure 3 and Figure 4 The pushing component includes a collar 8 rotatably mounted on the chip collection cylinder 10. The collar 8 has a plurality of push plates 9 arranged along its circumference that can abut against the end of the chip collection cylinder 10, and the collar 8 is connected to the output shaft through a transmission assembly.

[0040] The transmission assembly includes a transmission shaft 6 rotatably mounted on the lifting plate 4. One end of the transmission shaft 6 is connected to the collar 8 via a gear set 7, and the other end is connected to the output shaft via a toothed belt 17.

[0041] The bottom of the chip collection cylinder 10 is detachably equipped with a cover plate 11, which facilitates the discharge of waste chips inside the chip collection cylinder 10 by removing the cover plate 11 from the chip collection cylinder 10.

[0042] In detail, while the drill bit 12 is drilling the workpiece, the waste chips move upward along the threaded groove formed on the drill bit 12. Under the cutting of the reciprocating cutting blade 1401, the waste chips fall into the chip collection cylinder 10. At this time, the collar 8 rotates with the rotation of the drill shank 13, so that the push plate 9 pushes the waste chips on the chip collection cylinder 10. After being pushed by the push plate 9, the waste chips are directed towards the through groove 1001, so that the waste chips can enter the cavity for temporary storage, avoiding the accumulation of waste chips on the chip collection cylinder 10. With the coordinated work of the cutting blade 1401 and the push plate 9, automatic chip removal after drilling is effectively achieved.

[0043] Preferably, the chip collection cylinder 10 is configured with a conical surface structure near the inner ring of the drill bit 12.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
