Description

Technical Field

[0001] This utility model relates to the field of hole reamer technology, and in particular to a hole reamer. Background Technology

[0002] A reamer is an advanced piece of equipment used to process ring forgings. It is widely used in industries such as bearings, construction machinery, petrochemicals, aerospace, and power generation. Also known as a ring rolling mill, it is primarily used to enlarge the holes in ring forgings to the required size and shape. Reamers play a crucial role in horizontal directional drilling. During the reaming process, the reamer cuts and breaks up the soil and rock along a guide trajectory. Multiple stages of reaming and hole cleaning are typically required. The design and selection of the reamer directly affect construction efficiency and project quality. There are various types of reamers, each suitable for different applications. Geological conditions and construction requirements; barrel reamers; with functions of compressing and stabilizing the borehole wall, and wear-resistant materials are welded to the outer surface to correct the well wall. Barrel reamers are divided into general barrel type and flow channel type. The latter adopts a spiral flow channel, which is more conducive to the guidance of mud and rock cuttings. Plate reamers; use large cutting edge drilling, suitable for staged reaming, with a large reaming size range. Flying reamers; use carbide cutting teeth, suitable for reaming operations of various sizes. Roller cone reamers; suitable for different formation structures, with high strength and wear resistance, suitable for horizontal directional drilling.

[0003] Existing technology, with publication number CN222307118U, discloses a hole-reaming machine, including a worktable. Support columns are fixedly connected to the four corners of the lower end of the worktable. Moving mechanisms are provided at both ends of the worktable. A combined mechanism is provided at the upper end of the worktable, located between the two moving mechanisms. Two clamping mechanisms are provided at the upper end of the worktable, arranged symmetrically. This utility model provides a hole-reaming machine that, through the structural cooperation design of the two clamping mechanisms, allows for the clamping and fixing of steel pipes when hole reaming is required, thereby improving the stability during hole reaming.

[0004] When a worker needs to enlarge a workpiece, the worker places the workpiece on a reamer so that the worker can use the reamer to enlarge the hole. However, existing reamers generate a lot of metal shavings during use. Workers usually use a brush to clean up the metal shavings, which wastes a lot of time and leads to a decrease in the worker's work efficiency. Utility Model Content

[0005] The purpose of this invention is to solve the problem of reduced work efficiency of workers in the prior art, and to propose a hole-expanding machine.

[0006] This utility model adopts the following technical solution: a hole reamer, including a drill, a placement platform rotatably connected to the outer surface of the drill, a cleaning device provided on one side of the placement platform, the cleaning device including a rotating wheel, the rotating wheel being fixedly connected to one side of the placement platform, a support frame fixedly connected to the bottom end of the drill, the rotating wheel being rotatably connected to the inside of the support frame, a drive motor fixedly connected to one side of the support frame, an auxiliary wheel fixedly connected to the drive end of the drive motor, the auxiliary wheel being meshed with the surface of the rotating wheel, the other side of the auxiliary wheel being rotatably connected to the surface of the support frame, a collection box placed at the bottom end of the drill, the collection box being located below the placement platform, brackets fixedly connected to both sides of the support frame, a threaded hole opened on one side of the bracket, the threaded hole being aligned with a groove on one side of the placement platform, the bracket being able to cooperate with the support frame to achieve the purpose of supporting the bracket.

[0007] Preferably, the threaded hole is internally threaded with a threaded rod, which is inserted into a slot on one side of the placement platform. The threaded rod can cooperate with the threaded hole to guide the extension or retraction of the threaded rod.

[0008] Preferably, the lower surface of the placement platform is provided with an adsorption device, which includes a built-in groove. The built-in groove is opened on the lower surface of the placement platform, and a copper rod is fixedly connected to the inner wall of the built-in groove. The built-in groove can cooperate with the placement platform to achieve the purpose of storing magnetic blocks.

[0009] Preferably, a tray is fixedly connected to the bottom end of the copper rod, and a cylinder is fixedly connected to the upper surface of the tray. The tray can cooperate with the copper rod to support the tray and fix the cylinder.

[0010] Preferably, a magnetic block is fixedly connected to the drive end of the cylinder. The magnetic block is slidably connected to the outer surface of the copper rod. The magnetic block is placed inside the built-in groove and is magnetically connected to the placement platform. The magnetic block can cooperate with the cylinder to adjust the sliding of the magnetic block.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] This invention provides a hole reamer that overcomes the technical problems of low efficiency, cumbersome operation, and environmental pollution caused by existing hole reamers during metal shavings removal. It achieves an innovative solution with a compact structure, convenient operation, and significantly improved cleaning efficiency. The core of this hole reamer lies in its integrated rotatable platform, a drive motor-controlled rotation system, a cleaning mechanism linked with auxiliary wheels, and an adsorption device with magnetic attraction and release functions. Through the synergistic effect of these components, the cleaning process of metal shavings after hole reaming is automated, highly efficient, and precisely controlled.

[0013] Specifically, this hole-reaming machine uses a drive motor to drive an auxiliary wheel, which in turn adjusts a rotating wheel connected to one side of the placement platform, allowing the platform to rotate. During cleaning, the operator simply rotates the threaded rod to disengage the platform from its fixed connection and starts the drive motor, causing the platform to rotate 180°. At this point, the suction device at the bottom of the platform uses magnetic blocks to collect the metal shavings. After rotating to the collection position, the magnetic blocks are disengaged from the copper rod guide rail by a cylinder, losing their magnetism and allowing the metal shavings to fall precisely into the collection box below.

[0014] Compared to traditional hole-enlarging equipment that relies solely on manual brushing, lacks auxiliary devices, or suffers from a chaotic and inefficient cleaning process, this solution utilizes an integrated structure of "magnetic attraction + flipping + desorption + material discharge" to achieve a continuous cleaning process without manual intervention. This significantly improves the efficiency of workpiece changeover and cleaning, reducing downtime. Simultaneously, the controllable magnetic release of the magnetic blocks in the adsorption device, along with the copper rod guide rail and built-in groove design, enables directional recovery of metal shavings, effectively avoiding the problems of scattered, splashing, and environmental pollution associated with traditional cleaning processes.

[0015] Furthermore, the adsorption device can be switched between manual and automatic operation according to actual usage needs, satisfying both simple maintenance under low-frequency use and automatic linkage control under high-frequency use scenarios. The overall structural design has good versatility and adaptability. Through the above-mentioned structural synergy, this utility model not only improves the cleaning management efficiency of the hole enlarging machine, but also further ensures processing accuracy and workplace hygiene, realizing integrated control of the entire process from "hole enlarging" to "cleaning".

[0016] Therefore, while maintaining the stability of the main function of hole enlargement, this utility model achieves unexpected technical effects through a simple yet ingenious additional device, including significantly improved cleaning efficiency, reduced manual intervention, controlled metal shavings release process, simpler operation, and a cleaner environment. It is a creative and substantial improvement on the structure and function of existing hole enlargers. Attached Figure Description

[0024] Please see Figures 1-5 This utility model provides a technical solution: a hole reamer, wherein a cleaning device 3 is provided on one side of the placement table 2.

[0025] The specific setup and function of the cleaning device 3 and the adsorption device 4 will be explained in detail below.

[0026] In this embodiment: the cleaning device 3 includes a rotating wheel 32, which is fixedly connected to one side of the placement platform 2. A support frame 33 is fixedly connected to the bottom of the drilling rig 1. The rotating wheel 32 is rotatably connected to the inside of the support frame 33. A drive motor 31 is fixedly connected to one side of the support frame 33. An auxiliary wheel 36 is fixedly connected to the drive end of the drive motor 31. The auxiliary wheel 36 is meshed with the surface of the rotating wheel 32. The other side of the auxiliary wheel 36 is rotatably connected to the surface of the support frame 33. A collection box 38 is placed at the bottom of the drilling rig 1, and the collection box 38 is located below the placement platform 2.

[0027] Specifically, brackets 34 are fixedly connected to both sides of the support frame 33. A threaded hole 37 is opened on one side of the bracket 34. The threaded hole 37 is aligned with the slot on one side of the placement platform 2. The bracket 34 can cooperate with the support frame 33 to achieve the purpose of supporting the bracket 34.

[0028] Specifically, the threaded hole 37 has a threaded rod 35 inside, which is inserted into a slot on one side of the placement platform 2.

[0029] In this embodiment, the threaded rod 35 can cooperate with the threaded hole 37 to guide the threaded rod 35 to extend or retract.

[0030] In this embodiment: an adsorption device 4 is provided on the lower surface of the placement platform 2. The adsorption device 4 includes a built-in groove 45, which is opened on the lower surface of the placement platform 2. A copper rod 43 is fixedly connected to the inner wall of the built-in groove 45. The built-in groove 45 can cooperate with the placement platform 2 to achieve the purpose of storing the magnetic block 44.

[0031] Specifically, a tray 42 is fixedly connected to the bottom end of the copper rod 43, and a cylinder 41 is fixedly connected to the upper surface of the tray 42.

[0032] In this embodiment, the tray 42 can cooperate with the copper rod 43 to support the tray 42 and fix the cylinder 41.

[0033] Specifically, a magnetic block 44 is fixedly connected to the drive end of the cylinder 41. The magnetic block 44 is slidably connected to the outer surface of the copper rod 43. The magnetic block 44 is placed inside the built-in groove 45 and is magnetically connected to the placement platform 2.

[0034] In this embodiment, the magnetic block 44 can cooperate with the cylinder 41 to achieve the purpose of adjusting the sliding of the magnetic block 44.

[0035] Working principle: By setting up the cleaning device 3, when the worker needs to clean metal shavings, the worker rotates the threaded rod 35, which retracts and disengages from the placement platform 2. The worker then starts the drive motor 31, which drives the auxiliary wheel 36. The auxiliary wheel 36 adjusts the rotating wheel 32, which in turn drives the placement platform 2. The placement platform 2 rotates, carrying the metal shavings and the adsorption device 4. When the placement platform rotates 180 degrees, the adsorption device 4 is turned off, and the metal shavings lose their magnetic force and fall into the collection box 38. By setting up the cleaning device 3, the worker can effectively and conveniently clean metal shavings, avoiding the waste of a large amount of metal shavings during the cleaning process. This reduces the time required to clean up metal shavings, thereby improving the efficiency of workers. In addition, by setting up the adsorption device 4, when workers need to clean up metal shavings, after the placement platform 2 rotates 180 degrees, the workers start the cylinder 41. The cylinder 41 pulls the magnetic block 44. Guided by the copper rod 43, the magnetic block 44 disengages from the built-in groove 45, and the placement platform 2 loses the magnetic force of the magnetic block 44. The metal shavings on the surface of the placement platform 2 will fall off the placement platform 2. By setting up the adsorption device 4, it is possible to effectively facilitate workers to clean up metal shavings and prevent metal shavings from slipping when the placement platform 2 is rotated, thereby reducing the amount of metal shavings that workers need to clean up.
