Description

Technical Field

[0001] This utility model belongs to the field of drilling machine processing machinery technology, and relates to a waste collection device for drilling machines. Background Technology

[0002] As a fundamental piece of equipment in the machining field, drilling machines generate a large amount of debris and waste during the drilling process. Currently, most drilling machines lack effective automatic waste collection functions, relying mainly on manual cleaning by operators after processing. This method is not only inefficient and increases the labor intensity of workers, but also poses safety hazards due to the sharp metal chips, while interrupting continuous operation and affecting overall production efficiency.

[0003] Existing automated waste collection devices often suffer from complex structures and high costs. For example, the solution disclosed in Chinese patent CN216828782U uses complex mechanisms such as lead screws, gear racks, and planetary gear systems to achieve the rotation and cleaning of the cleaning disc. Although it achieves automation, the rotation and cleaning may cause waste to splash, scatter, or leave cleaning dead spots.

[0004] To address the aforementioned problems, this utility model proposes a waste collection device for drilling machines. Utility Model Content

[0005] To address the problems existing in the background technology, this utility model proposes a waste collection device for drilling machines.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a waste collection device for a drilling machine, including a workbench, wherein a through groove is provided on the upper surface of the workbench, and a collection box connected to the through groove is provided inside the workbench. Above the workbench is a long rod that can move vertically, and a drive mechanism for driving the drill bit is fixedly installed in the middle of the long rod. Two cleaning units are symmetrically arranged on both sides of the drive mechanism on the long rod. Each cleaning unit is driven to lift and lower by a cylinder fixed on the long rod. The bottom of the cleaning unit is provided with a cleaning component, and a linkage structure is provided between the cleaning unit and the telescopic end of the cylinder. When the cylinder drives the cleaning unit to descend and contact the worktable, the cylinder continues to extend, which, through the linkage structure, causes the cleaning unit to move horizontally, thereby sweeping the waste material into the collection box through the trough via the cleaning component.

[0007] Preferably, the drive mechanism is a servo motor, whose output shaft is arranged in the vertical direction and is coaxially and detachably connected to the drill bit.

[0008] Preferably, an electric guide rail is fixedly installed on the upper surface of the workbench, and the long rod is slidably installed on the electric guide rail.

[0009] Preferably, the cleaning unit includes a movable block, and the linkage structure includes a slider fixed to the telescopic end of the cylinder and a guide rod inclinedly fixed to the movable block. The slider and the guide rod are slidably connected, and a first spring is sleeved on the guide rod.

[0010] Preferably, the cleaning unit further includes a movable plate that is horizontally slidably connected to the end of the movable block, and a second brush installed at the bottom of the movable plate, the second brush constituting the cleaning component.

[0011] Preferably, a limit rod is horizontally fixed at the end of the movable block, the movable plate is slidably connected to the limit rod through a connecting part at its end, and a second spring acting on the connecting part is sleeved on the limit rod.

[0012] Preferably, a first brush for cleaning the drill bit is installed on the side of the movable plate near the drive mechanism.

[0013] Preferably, the bottom of the drive mechanism is provided with a wedge-shaped part, and the upper surface of the movable plate is provided with a mating part that cooperates with the wedge-shaped part; when the movable plate rises to be flush with the drive mechanism, the wedge-shaped part drives the movable plate to move horizontally outward against the elastic force of the second spring by squeezing the mating part.

[0014] Preferably, a vertical plate is fixed to the bottom of the movable plate, and a plurality of ball bearings are rotatably mounted on the lower end face of the vertical plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects: First, this invention creatively employs a cylinder-driven tilting slide mechanism, directly converting the single vertical extension and retraction motion of the cylinder into the horizontal linear sweeping motion of the cleaning brush. This core transmission mechanism consists of only a few common linear components such as a slider, tilting guide rod, and spring, completely eliminating the need for a complex gear transmission system.

[0016] Secondly, this invention utilizes a spring and movable plate structure, allowing the cleaning unit to automatically move aside and brush the drill bit during its descent, effectively removing shavings and oil residue adhering to the drill bit. This avoids the problem of shavings buildup affecting subsequent processing accuracy and drill bit lifespan, achieving comprehensive cleaning of the processing area.

[0017] Finally, compared to rotary cleaning, the second brush of this invention moves in a straight line on the worktable surface. This motion continuously and thoroughly pushes waste into the collection channel, effectively avoiding the problems of waste splashing, scattering, or cleaning dead corners that may occur with rotary cleaning. This results in higher waste collection efficiency and a more thorough effect. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 5 As shown, the technical solution adopted by this utility model is as follows: A waste collection device for a drilling machine includes a worktable 1. A through groove 2 is provided on the upper surface of the worktable 1, which serves as a waste collection channel. A collection box 3 is provided inside the worktable 1, and the collection box 3 is connected to the through groove 2 for centralized storage of the cleaned waste. An electric guide rail 4 is fixedly installed on the upper surface of the worktable 1. Two electric guide rails 4 are arranged in parallel, and a long rod 5 is slidably installed between them. The long rod 5 can be driven to move vertically through the electric guide rails 4.

[0022] A mounting block 6 is fixedly installed in the middle of the long rod 5. A servo motor 7 is fixedly installed below the mounting block 6, and the output shaft of the servo motor 7 is set in the vertical direction. The output end of the servo motor 7 is coaxially and detachably mounted with a drill bit 14, which facilitates the replacement and maintenance of the drill bit 14. When the servo motor 7 is started, it can drive the drill bit 14 to perform rotary cutting operations.

[0023] Two cleaning units are symmetrically arranged on both sides of the mounting block 6. Two cylinders 8 are fixedly installed on the long rod 5. The telescopic ends of the cylinders 8 are arranged in the vertical direction, which can directly drive the cleaning units to move up and down.

[0024] Each cleaning unit includes a movable block 9, which is tilted so that the end of the movable block 9 furthest from the mounting block 6 is higher than the end of the movable block 9 closest to the mounting block 6.

[0025] The movable block 9 and the cylinder 8 are connected by a linkage structure.

[0026] The linkage structure includes: a guide rod 11, a slider 10, and a first spring 12.

[0027] A sliding groove parallel to the movable block 9 is formed on the movable block 9. A guide rod 11 is fixedly installed within the sliding groove, and the inclination direction of the guide rod 11 is consistent with that of the movable block 9. A slider 10 is fixedly installed at the output end of the cylinder 8, and the slider 10 is slidably connected to the guide rod 11. A first spring 12 is sleeved on the guide rod 11, with one end fixed to the end of the sliding groove and the other end fixed to the slider 10. When the cylinder 8 drives the slider 10 to move, the first spring 12 can buffer and transmit the force.

[0028] The cleaning unit also includes a movable plate 15, which is connected to the end of the movable block 9 via a connecting part 16. A limit rod 23 is horizontally fixed to the end of the movable block 9, and a clearance groove on the connecting part 16 forms a sliding fit with the limit rod 23. This connection method ensures the horizontal freedom of movement of the movable plate 15 and provides reliable guidance. A second spring 22 is sleeved on the limit rod 23. One end of the second spring 22 is fixed to the limit rod 23, and the other end is fixed to the side wall of the clearance groove. The second spring 22 enables the movable plate 15 to reset.

[0029] A first brush 19 is fixedly installed on the side wall of the movable plate 15 near the mounting block 6. This first brush 19 is used to scrub the surface of the drill bit 14 during the cleaning process. A second brush 13 is detachably installed on the bottom of the movable plate 15. This detachable connection facilitates the replacement and maintenance of the second brush 13. A vertical plate 20 is also fixed to the bottom of the movable plate 15. A plurality of ball bearings 21 are evenly distributed on the lower end surface of the vertical plate 20. These ball bearings 21 can reduce the frictional resistance between the movable plate 15 and the worktable 1 when the movable plate 15 moves.

[0030] A wedge-shaped portion 17 is provided at the bottom of the servo motor 7, and correspondingly, a mating portion 18 is provided on the upper surface of the movable plate 15. When the movable plate 15 rises to the point where its top surface is flush with the bottom wall of the servo motor 7, the wedge-shaped portion 17 and the mating portion 18 interact, which can force the movable plate 15 to move horizontally, thereby realizing the automatic reset of the cleaning unit.

[0031] The specific working process is as follows: After the device is started, it first enters the drilling stage. The servo motor 7 drives the drill bit 14 to rotate at high speed, while the electric guide rail 4 drives the long rod 5 to move downward, so that the drill bit 14 can drill the workpiece. During this process, the generated chips and waste are scattered on the surface of the worktable 1.

[0032] After drilling is completed, the cleaning preparation stage begins. The electric guide rail 4 drives the long rod 5 to rise, causing the drill bit 14 to exit the workpiece. Subsequently, the two cylinders 8 extend simultaneously, pushing the cleaning unit downward. Driven by the cylinders 8, the movable block 9 descends along the inclined direction, causing the movable plate 15 and its first brush 19 and second brush 13 to move downward synchronously.

[0033] When the ball bearing 21 at the bottom of the movable plate 15 contacts the surface of the worktable 1, the device enters the cleaning phase. At this time, the movable plate 15 stops descending, but the cylinder 8 continues to extend. This continued extension forces the slider 10 to slide along the inclined guide rod 11, while compressing the first spring 12. Due to the inclined setting of the guide rod 11, the sliding of the slider 10 causes the movable block 9 to move horizontally away from the axis of the mounting block 6.

[0034] The horizontal movement of the movable block 9 is transmitted to the movable plate 15 via the limit rod 23 and the second spring 22, causing the movable plate 15 to move horizontally along with the second brush 13. At this time, the second brush 13 is pressed tightly against the surface of the worktable 1, and its horizontal movement pushes the waste material scattered around the drill bit 14 towards the through groove 2. The waste material falls into the collection box 3 below through the through groove 2, completing the waste material collection.

[0035] As the movable plate 15 descends, when it moves to a position below the servo motor 7, the elastic force of the second spring 22 pushes the movable plate 15 towards the drill bit 14, causing the first brush 19 to adhere tightly to the surface of the drill bit 14. As the drill bit 14 rotates, the first brush 19 effectively removes the debris adhering to the drill bit 14, completing the drill bit cleaning.

[0036] Finally, the system enters the reset phase. Cylinder 8 begins to retract, causing the cleaning unit to rise. When the movable plate 15 rises to a position where its upper end face is flush with the lower end face of the servo motor 7, the mating part 18 on the movable plate 15 contacts the wedge-shaped part 17 of the servo motor 7. The movable plate 15 continues to rise, and under the action of the inclined surface of the wedge-shaped part 17, the movable plate 15 is pushed away from the drill bit 14, causing the first brush 19 to disengage from the drill bit 14, and the second brush 13 to lift off the surface of the worktable 1. The cleaning unit is fully reset and ready to execute the next work cycle.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
