Description

Technical Field

[0001] This application relates to the field of machining, and more specifically, to a dust cover for a bench drill. Background Technology

[0002] A bench drill, also known as a bench drill, is a common metalworking machine tool. It uses a lifting device to drive a spindle equipped with a drill bit to move vertically relative to a worktable, thereby performing drilling, reaming, and other machining operations on workpieces fixed to the worktable. Due to its simple structure and ease of operation, it is widely used in machinery manufacturing, repair shops, and mold processing.

[0003] However, during drilling, especially when machining metal materials, a large amount of metal debris is generated between the drill bit and the workpiece. Driven by the high-speed rotation of the drill bit, this debris is flung outwards at extremely high speeds. The sharp edges of these flying metal fragments pose a serious safety risk, easily causing cuts or injuries to the operator's eyes, face, and hands. Simultaneously, the scattered debris may enter the drill press's guide rails, lead screws, and other precision moving parts, accelerating their wear and affecting the equipment's accuracy and lifespan. Cleaning up the debris scattered on the ground and throughout the equipment is tedious and increases additional maintenance costs. Utility Model Content

[0004] This application provides a dust cover for a bench drill, which can adsorb and collect debris generated during the operation of the drill.

[0005] Specifically, this application is implemented through the following technical solution: This application provides a dust cover for a bench drill press. The drill press uses a lifting device to drive the drill bit mounting base to move up and down relative to the worktable. The dust cover includes: A cover is configured to be fixedly installed and cover the working surface of the workbench, the cover including a first sidewall; An electromagnet module is embedded in the inner side of the first sidewall and is used to generate a magnetic field when energized during processing to attract ferromagnetic debris. The chip collection box is installed in a retractable manner at the bottom of the cover and is located directly below the magnetic field area generated by the electromagnet module; The electromagnet module is configured to be powered off after processing, and the adsorbed debris falls off under gravity and directly into the chip collection box.

[0006] Optionally, a scraper mechanism is also included, which includes a scraper body and a rotating shaft. The rotating shaft is rotatably mounted on the first side wall, and its axis is perpendicular to the plane of the first side wall. The scraper body is fixedly connected to the rotating shaft and can sweep across the surface of the electromagnet module as the rotating shaft rotates.

[0007] Optionally, the electromagnet module is a long strip structure arranged in a horizontal direction; the mounting position of the rotating shaft is higher than the electromagnet module, and the scraper body is in contact with the surface of the electromagnet module in a natural hanging state; the scraper body is configured to swing around the rotating shaft in the left and right direction to scrape off the debris on the surface of the electromagnet module.

[0008] Optionally, a shaft hole for mounting the rotating shaft is provided on the first sidewall; the scraper mechanism further includes a gripping part located on the outside of the first sidewall, and one end of the rotating shaft passes through the shaft hole and is connected to the gripping part; The inner side of the first sidewall is recessed into a receiving groove corresponding to the storage position of the scraper body. When the scraper body is rotated to align with the receiving groove, the scraper body can be received in the receiving groove by pulling the gripping part outward to drive the rotating shaft to move axially.

[0009] Optionally, the scraper mechanism further includes a limiting member, which is connected to the gripping part via a flexible connector; when the scraper body is received in the receiving groove and the rotating shaft is pulled outward, the limiting member is configured to be detachably fixed to the exposed portion of the rotating shaft to prevent the rotating shaft from retracting.

[0010] Optionally, the surface of the grip portion is provided with anti-slip texture.

[0011] Optionally, the cover includes at least one bent door, which is formed by a first sub-door and a second sub-door fixedly connected at an angle; the first sub-door is rotatably connected to the cover side wall adjacent to the first side wall via a hinge; the second sub-door is positioned opposite to the first side wall when the bent door is closed.

[0012] Optionally, there are two bent door bodies, namely a first bent door body and a second bent door body, which are rotatably connected to two adjacent cover side walls of the first side wall via hinges; when closed, the first bent door body and the second bent door body are fastened to each other in front of the first side wall.

[0013] Optionally, the first bent door body has a protrusion at its mating edge, and the second bent door body has a groove at its mating edge that matches the protrusion; when the first bent door body and the second bent door body are closed, the protrusion and the groove engage with each other.

[0014] This application provides a dust cover for a bench drill, comprising a cover body, an electromagnet module, and a chip collection box. The cover body constitutes a physical barrier, effectively blocking high-speed flying metal chips during processing, preventing injury to operators or pollution of the external environment, thus solving the most basic safety and protection problems. Secondly, during the operation of the bench drill, the electromagnet module is energized, generating a strong magnetic field that actively attracts and fixes the scattered ferromagnetic chips to the first side wall of the cover body, preventing chips from accumulating randomly on various surfaces inside the cover. After operation, the electromagnet module is de-energized, the magnetic field disappears, and the attracted chips fall directionally and centrally into the chip collection box below under their own gravity. When a certain amount of ferromagnetic chips accumulates in the chip collection box, the operator can pull out the chip collection box to collect the chips. This embodiment eliminates the need to open the cover for cumbersome and potentially polluting internal cleaning, significantly improving the convenience, efficiency, and cleanliness of cleaning.

Detailed Implementation

[0017] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0018] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0019] This application provides a dust cover for a bench drill press, see reference. Figure 1 and Figure 2 The drilling machine drives the drill bit mounting base to rise and fall relative to the worktable B via lifting device A, combined with... Figure 3 and Figure 4 The dust cover includes a cover body 100, an electromagnet module 200, and a chip collection box 300. The cover body 100 is fixedly installed and covers the working surface of the workbench B, and includes a first side wall 110. The electromagnet module 200 is embedded in the inner side of the first side wall 110 and is used to generate a magnetic field during processing to attract ferromagnetic chips. The chip collection box 300 is retractable and installed at the bottom of the cover body 100, directly below the magnetic field area generated by the electromagnet module 200. The electromagnet module 200 is configured such that after processing is completed, the power is turned off, and the attracted chips fall off under gravity and directly into the chip collection box 300.

[0020] First, the cover 100 constitutes a physical barrier, effectively blocking high-speed flying metal debris during processing, preventing injury to operators or pollution of the external environment, thus solving the most basic safety and protection issues. Second, during the operation of the bench drill, the electromagnet module 200 is energized, generating a strong magnetic field that actively attracts and fixes the scattered ferromagnetic debris to the first side wall 110 of the cover 100, preventing debris from accumulating randomly on various surfaces inside the cover 100, such as the top and other side walls. After operation, the electromagnet module 200 is de-energized, the magnetic field disappears, and the attracted debris falls directionally into the chip collection box 300 directly below under its own gravity. When a certain amount of ferromagnetic debris accumulates in the chip collection box 300, the operator can pull out the chip collection box 300 to collect the debris. This embodiment eliminates the need to open the cover 100 for tedious and potentially polluting internal cleaning, significantly improving the convenience, efficiency, and cleanliness of cleaning.

[0021] Combination Figure 5 In one embodiment, the dust cover further includes a scraper mechanism 400, which includes a scraper body 410 and a rotating shaft 420. The rotating shaft 420 is rotatably mounted on the first sidewall 110, and its axis is perpendicular to the plane of the first sidewall 110. The scraper body 410 is fixedly connected to the rotating shaft 420 and can sweep across the surface of the electromagnet module 200 as the rotating shaft 420 rotates. After the electromagnet is de-energized, some debris, especially small or oily debris, may remain due to residual magnetism or surface adhesion. In this embodiment, after the electromagnet is de-energized, the operator can manually rotate the scraper to sweep across the surface of the electromagnet. Through the mechanical scraping of the adsorption surface by the scraper body 410, residual magnetism and static friction can be effectively overcome, forcibly peeling off the residual debris and ensuring that it can fall smoothly into the debris collection box 300, thereby improving the reliability and thoroughness of the entire collection system.

[0022] In one embodiment, the electromagnet module 200 is an elongated structure arranged horizontally; the rotating shaft 420 is mounted above the electromagnet module 200, and the scraper body 410 contacts the surface of the electromagnet module 200 in a naturally drooping state; the scraper body 410 is configured to swing left and right about the rotating shaft 420 to scrape away debris from the surface of the electromagnet module 200. In this embodiment, the rotating shaft 420 is mounted above the electromagnet module 200, allowing the scraper to hang naturally in contact with the surface, and its swing axis is located on one side of the cleaning area rather than at the end. Compared to a long scraper that rotates from the side end, this design allows for cleaning of the entire vertical area using a shorter scraper body 410, resulting in a more compact structure, requiring less operating torque, and requiring less effort to operate.

[0023] Combination Figure 5 and Figure 6In one embodiment, the first sidewall 110 is provided with a shaft hole 111 for mounting the rotating shaft 420; the scraper mechanism 400 also includes a gripping part 430 provided on the outer side of the first sidewall 110, and one end of the rotating shaft 420 passes through the shaft hole 111 and is connected to the gripping part 430; the inner side of the first sidewall 110 is provided with a receiving groove 112 corresponding to the storage position of the scraper body 410; when the scraper body 410 is rotated to be aligned with the receiving groove 112, the rotating shaft 420 can be driven to move axially by pulling the gripping part 430 outward, so that the scraper body 410 can be received in the receiving groove 112.

[0024] In this embodiment, when the scraper is not needed, it can be rotated to align with the receiving groove 112, and then the gripping part 430 can be pulled outward to slide the entire scraper body 410 into the receiving groove 112 on the side wall. After storage, the scraper is separated from the surface of the electromagnet module 200, completely avoiding its obstruction and interference with the debris adsorption path, and ensuring the maximum collection efficiency of the electromagnet during processing. Storing the scraper inside the wall of the cover 100 does not occupy additional internal working space, and also prevents the scraper from being damaged by accidental collisions. The two-step operation of "rotating and aligning" followed by "axially pulling out for storage" is logically clear, simple to execute, and is a clever and user-friendly storage solution.

[0025] refer to Figure 6 In one embodiment, the scraper mechanism 400 further includes a limiting member 440, which is connected to the gripping portion 430 via a flexible connector. When the scraper body 410 is received in the receiving groove 112 and the rotating shaft 420 is pulled outward, the limiting member 440 is configured to be detachably fixed to the exposed portion of the rotating shaft 420 to prevent the rotating shaft 420 from retracting.

[0026] In this embodiment, after the scraper is pulled out and retracted into the receiving groove 112, a limiting member 440, such as an inner arc-shaped sleeve, connected to the gripping part 430 via a flexible connector 441, is fitted onto the exposed rotating shaft 420. The limiting member 440 mechanically prevents the rotating shaft 420 from retracting into the cover 100 under internal force, thereby stably locking the scraper in the retracted position. Moreover, the limiting member 440 is connected to the main body via a flexible connector 411, such as a chain or rope, which not only achieves a detachable function but also effectively prevents the limiting member 440 from being lost due to careless placement after being removed, allowing it to be easily retrieved when needed.

[0027] In one embodiment, the surface of the grip portion 430 is provided with anti-slip texture. Providing anti-slip texture, such as a mesh pattern or vertical stripes, on the surface of the grip portion 430 can significantly increase the friction between the hand and the grip portion 430. This makes operation more stable and less prone to slipping when rotating the scraper and pulling axially, especially in working environments where hands may be contaminated with oil, thus improving operational safety and comfort.

[0028] refer to Figure 5 In one embodiment, the cover 100 includes at least one bent door 500, which is fixedly connected by a first sub-door 501 and a second sub-door 502 and is formed at an angle; the first sub-door 501 is rotatably connected to the side wall of the cover 100 adjacent to the first side wall 110 via a hinge; the second sub-door 502 is disposed opposite to the first side wall 110 when the bent door 500 is closed.

[0029] The bent door 500, such as an L-shaped door, provides a larger operating opening when opened compared to a traditional hinged door, thanks to the bend. For a single bent door 500, the resulting "gap" space allows the operator to easily insert longer workpieces such as sheets or profiles by sliding or rotating them, without interfering with the door structure.

[0030] In one embodiment, there are two bent door bodies 500, namely a first bent door body 510 and a second bent door body 520, which are rotatably connected to the side walls of two adjacent cover bodies 100 via hinges; when closed, the first bent door body 510 and the second bent door body 520 are fastened to each other in front of the first side wall 110.

[0031] Furthermore, for the two double-leaf curved doors 500, when both doors are opened simultaneously, almost the entire front area of ​​the workbench B is completely open, which greatly facilitates the placement of large workpieces with wide dimensions or irregular shapes, fundamentally solving the problem of difficulty in placing materials with traditional small doors.

[0032] structure Figure 5 and Figure 7 In one embodiment, the mating edge of the first bent door body 510 is provided with a protrusion 511, and the mating edge of the second bent door body 520 is provided with a groove 521 that matches the protrusion 511. When the first bent door body 510 and the second bent door body 520 are closed, the protrusion 511 and the groove 521 engage with each other. The interlocking protrusion 511 and groove 521 on the mating edges of the first and second bent door bodies 520 form a "maze-like" sealing structure. When the door is closed, this structure makes the path of flying debris tortuous, effectively preventing fine debris from escaping directly from the door gap, improving the overall sealing performance of the cover 100, and further enhancing the protective effect.

[0033] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
