Description

Technical Field

[0001] This utility model relates to the field of metal processing equipment technology, specifically to a drilling device for the production of metal parts. Background Technology

[0002] Drilling is a critical process in metal parts manufacturing, and its accuracy and efficiency directly affect product quality and production costs. However, existing drilling devices generally suffer from the following technical bottlenecks: traditional drilling devices only use simple brushes or air blowers to clean metal shavings from the vise and drilling area. This is ineffective at cleaning small debris embedded in the jaws or adhering to the workpiece surface. Metal shavings that are not cleaned in time can easily accumulate in the sliding parts of the vise, causing the jaws to jam.

[0003] According to a disclosed drilling apparatus for metal part production (Publication No.: CN221270386U), it includes a support device, a drilling device, and a fixing device. The support device is placed on a plane. The fixing device includes a fixing seat, a fixing rod, an adjusting rod, and adjusting components. The fixing seat is disposed on the support device, and at least one fixing rod is disposed on the fixing seat. The adjusting rod is slidably fitted at both ends of the fixing rod, and multiple adjusting rods together form a defined space in which the metal part to be drilled is located. Multiple adjusting components are disposed on the support device, and the multiple adjusting components are respectively connected to multiple adjusting rods and drive the multiple adjusting rods to move closer or further apart. The drilling device is disposed on the support device and drills the metal part to be drilled within the defined space. This application has the effect of improving the safety of drilling.

[0004] Existing technologies include improvements such as adding vacuum cleaners or automatic brushes, but these still fail to solve the problems of low automation and insufficient collection efficiency. Therefore, we propose a drilling device for metal parts production that features automated and efficient cleaning, low-vibration transmission, and collection without dead angles. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a drilling device for the production of metal parts, which solves the technical problem of debris cleaning and collection in drilling operations in mass production scenarios in related technologies.

[0006] According to one aspect, at least one embodiment of the present invention provides a drilling device for the production of metal parts, comprising: a base, a support rod fixedly connected to the top of the base, a transmission box provided at one end of the support rod, a drill shaft provided at the bottom of the transmission box, a cover plate fixedly connected to the top of the transmission box, a bench vise provided at the top of the base, and a cleaning device provided at the bottom of the cover plate. The cleaning device includes a motor, the top of which is fixedly connected to the bottom of the cover plate. One end of the motor output shaft is fixedly connected to a rotating shaft, and the end of the rotating shaft away from the motor is fixedly connected to a driving bevel gear. The top of the base is fixedly connected to a support plate, and one side of the support plate is rotatably connected to a rotating shaft, one end of which is fixedly connected to a driven bevel gear. The driving bevel gear and the driven bevel gear mesh with each other. The other end of the rotating shaft is fixedly connected to a wheel, and the side of the wheel is fixedly connected to an eccentric shaft. The side of the support plate is fixedly connected to a support shaft, and one end of the support shaft is rotatably connected to a rack. The inner wall of the rack is slidably connected to the circumferential surface of the eccentric shaft. The top of the bench vise is slidably connected to a cleaning rod, and the side of the cleaning rod is fixedly connected to a rack. The rack and the rack mesh with each other.

[0007] For example, in at least one embodiment of the present invention, a drilling device for producing metal parts further includes: a support column fixedly connected to the side of the cleaning rod, a support base fixedly connected to the top of the bench vise, and the support column slidably connected to the inner wall side of the support base. The sliding guide of the support column within the support base provides rigid support for the reciprocating motion of the cleaning rod, preventing the cleaning rod from bending or swaying due to eccentric force, and improving the stability and thoroughness of metal shavings removal.

[0008] The motor has a stabilizing column on its circumference. One end of the stabilizing column is fixedly connected to the bottom of the cover plate, and the inner circumferential surface of the stabilizing column is lined with sound-absorbing cotton. The stabilizing column rigidly connects the cover plate and the motor, reducing the vibration amplitude when the motor is running at high speed. The sound-absorbing cotton filling the inner wall of the stabilizing column absorbs the noise of the motor operation and improves the working environment.

[0009] The side of the bench vise is not located on the displacement trajectory of the cleaning rod, and the side of the cleaning rod is in contact with the side of the vise jaws. The displacement trajectory of the cleaning rod avoids the main structure of the bench vise to prevent interference with the vise during cleaning. The side of the cleaning rod is close to the edge of the jaws, which can effectively remove metal shavings accumulated in the jaw gaps during drilling.

[0010] The diameter of the driving bevel gear is equal to the diameter of the driven bevel gear, and the axes of the driving and driven bevel gears are perpendicular to each other. The design of the driving and driven bevel gears having the same diameter ensures a transmission ratio of 1:1, achieving synchronous transmission of rotational speed and avoiding lag in the movement of the sweeping lever due to differences in speed ratio.

[0011] According to another aspect, at least one embodiment of the present invention also provides a drilling device for the production of metal parts, comprising: a collecting device disposed on the side of the bench vise away from the cleaning device, the collecting device including a collecting box disposed on the top of a base; a driving pulley fixedly connected to the circumferential surface of a second rotating shaft; a transmission belt disposed on the circumferential surface of the driving pulley; a support plate two fixedly connected to the top of the base; a threaded rod rotatably connected to the inner wall of the support plate two; a driven pulley fixedly connected to one end of the threaded rod; the driven pulley being driven by the driving pulley via the transmission belt; a threaded sleeve threadedly connected to the circumferential surface of the threaded rod; a transmission rod fixedly connected to the circumferential surface of the threaded sleeve; a rotating shaft three fixedly connected to one end of the transmission rod; a flattening rubber fixedly connected to the circumferential surface of the rotating shaft three; and the flattening rubber being located inside the collecting box.

[0012] For example, in at least one embodiment of the present invention, a drilling device for producing metal parts further includes: a support plate three rotatably connected to the circumferential surface of the threaded rod, and the bottom of the support plate three being fixedly connected to the top of the base. The support plate three is fixed to the base, providing an intermediate support point for the threaded rod and reducing radial bending when the length-to-diameter ratio of the threaded rod is large.

[0013] The threaded rod has a thread length equal to the inner wall length of the collection box, and the flattening rubber is equal to the inner wall width of the collection box. The effective thread length of the threaded rod is equal to the inner wall length of the collection box, ensuring that the flattening rubber can cover the entire length of the collection box, and the width of the flattening rubber is consistent with the inner wall of the collection box, eliminating dead corners.

[0014] The diameter of the driving pulley is equal to the diameter of the driven pulley, and the side surfaces of the driving and driven pulleys are located on the same parallel plane. The equal diameter design of the driving and driven pulleys ensures consistent rotational speeds, prevents belt slippage, and the coplanar layout reduces lateral belt offset, extending the service life of both the pulleys and the belt.

[0015] The side of the collection box contacts the side of the bench vise, and the collection box is snapped onto the top of the base. The side of the collection box is in close contact with the bench vise, ensuring that metal shavings generated during drilling fall directly into the box, reducing shavings splashing; the snap-fit ​​structure facilitates quick disassembly and cleaning.

[0016] The beneficial effects of the embodiments of this utility model are as follows: 1. In this utility model, the cleaning device achieves efficient automatic cleaning of metal chips in the drilling area through bevel gear transmission and rigid guide structure. The motor drives the active bevel gear and the driven bevel gear to mesh perpendicularly, converting the rotational motion of the motor into the eccentric rotation of the wheel. The eccentric shaft drives the rack to move back and forth, thereby driving the cleaning rod to slide linearly along the side of the vise jaws. The power loss is low, the transmission efficiency is high, and the cleaning action is guaranteed to avoid manual intervention.

[0017] 2. In this utility model, the collection device achieves automated collection and organization of metal shavings through pulley linkage transmission and a push-flat structure without dead angles. The rotating shaft two drives the driven pulley to rotate through the active pulley and transmission belt, which synchronously drives the threaded rod to rotate, causing the threaded sleeve to move back and forth along the threaded rod, thereby driving the push-flat rubber to slide laterally in the collection box. The active pulley and the driven pulley are arranged with the same diameter and coplanar layout to ensure consistent speed and smooth transmission, thus realizing the synchronization of cleaning and collection actions.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0022] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product.

[0026] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] like Figures 1-5 As shown, it illustrates a drilling device for producing metal parts according to an embodiment of the present invention, comprising: a base 1, a support rod 2 fixedly connected to the top of the base 1, a transmission box 3 provided at one end of the support rod 2, a drill shaft 4 provided at the bottom of the transmission box 3, a cover plate 5 fixedly connected to the top of the transmission box 3, a bench vise 6 provided at the top of the base 1, and a cleaning device 7 provided at the bottom of the cover plate 5. The cleaning device 7 includes a motor 701. The top of the motor 701 is fixedly connected to the bottom of the cover plate 5. One end of the output shaft of the motor 701 is fixedly connected to a rotating shaft 702. The end of the rotating shaft 702 away from the motor 701 is fixedly connected to a driving bevel gear 703. The top of the base 1 is fixedly connected to a support plate 704. One side of the support plate 704 is rotatably connected to a rotating shaft 705. One end of the rotating shaft 705 is fixedly connected to a driven bevel gear 706. The driving bevel gear 703 and the driven bevel gear 706 are connected in series. The two vises are intermeshing. The other end of the rotating shaft 705 is fixedly connected to the rotating wheel 707. The side of the rotating wheel 707 is fixedly connected to the eccentric shaft 708. The side of the support plate 704 is fixedly connected to the support shaft 709. One end of the support shaft 709 is rotatably connected to the toothed rod 710. The inner wall of the toothed rod 710 is slidably connected to the circumferential surface of the eccentric shaft 708. The top of the bench vise 6 is slidably connected to the cleaning rod 711. The side of the cleaning rod 711 is fixedly connected to the rack 712. The toothed rod 710 and the rack 712 mesh with each other.

[0028] In some examples, a support column is fixedly connected to the side of the sweeping bar 711, and a support base is fixedly connected to the top of the bench vise 6. The support column is slidably connected to the inner wall of the support base. The sliding guide of the support column within the support base provides rigid support for the reciprocating motion of the sweeping bar 711, preventing the sweeping bar 711 from bending or shaking due to eccentric force, thus improving the stability and thoroughness of metal shavings cleaning.

[0029] A stabilizing column is provided on the circumferential surface of the motor 701. One end of the stabilizing column is fixedly connected to the bottom of the cover plate 5, and the inner circumferential surface of the stabilizing column is provided with sound-absorbing cotton. The stabilizing column rigidly connects the cover plate 5 and the motor 701, reducing the vibration amplitude when the motor 701 is running at high speed. The sound-absorbing cotton filling the inner wall of the stabilizing column absorbs the operating noise of the motor 701 and improves the working environment.

[0030] The side of the bench vise 6 is not located on the displacement trajectory of the cleaning rod 711, but the side of the cleaning rod 711 is in contact with the side of the jaws of the bench vise 6. The displacement trajectory of the cleaning rod 711 avoids the main structure of the bench vise 6 to prevent interference with the bench vise 6 during cleaning. The side of the cleaning rod 711 is close to the edge of the jaws, which can effectively remove metal shavings accumulated in the jaw gaps during drilling.

[0031] The diameter of the driving bevel gear 703 is equal to the diameter of the driven bevel gear 706, and the axes of the driving bevel gear 703 and the driven bevel gear 706 are perpendicular to each other. The design of the equal diameter of the driving bevel gear 703 and the driven bevel gear 706 ensures a transmission ratio of 1:1, realizes synchronous transmission of speed, and avoids lag in the movement of the sweeping rod 711 due to speed ratio differences.

[0032] For example, such as Figures 1-5As shown, after the motor 701 starts, the output shaft drives the rotating shaft 702 to rotate, and the driving bevel gear 703 fixed at the end of the rotating shaft 702 rotates synchronously. The driving bevel gear 703 meshes perpendicularly with the driven bevel gear 706, transmitting power to the rotating shaft 705, causing the rotating wheel 707 to rotate around the axis of the rotating shaft 705. When the eccentric shaft 708 on the side of the rotating wheel 707 rotates with the rotating wheel 707, its circumferential surface slides on the inner wall of the rack 710, pushing the rack 710 to move along the support shaft 709. The rack 710 meshes with the rack 712 on the side of the cleaning rod 711. When the rack 710 moves, it drives the cleaning rod 711 to slide linearly along the jaw direction at the top of the vise 6. The support column on the side of the cleaning rod 711 slides and guides within the support seat to ensure the straightness of the movement trajectory. Its side is in close contact with the edge of the jaw of the vise 6, scraping off the metal shavings generated during drilling along the jaw gap.

[0033] like Figures 1-5 As shown, this invention illustrates a drilling device for producing metal parts according to another embodiment of the present invention, comprising: a bench vise 6 with a collecting device 8 disposed on the side away from the cleaning device 7; the collecting device 8 includes a collecting box 801 disposed on the top of a base 1; a drive pulley 802 fixedly connected to the circumferential surface of a rotating shaft 705; a transmission belt 803 disposed on the circumferential surface of the drive pulley 802; and a support plate 804 fixedly connected to the top of the base 1, the inner wall of the support plate 804 rotating. A threaded rod 806 is connected, and a driven pulley 805 is fixedly connected to one end of the threaded rod 806. The driven pulley 805 is connected to the driving pulley 802 through the transmission belt 803. A threaded sleeve 807 is threadedly connected to the circumferential surface of the threaded rod 806. A transmission rod 808 is fixedly connected to the circumferential surface of the threaded sleeve 807. A rotating shaft 809 is fixedly connected to one end of the transmission rod 808. A flattening rubber 810 is fixedly connected to the circumferential surface of the rotating shaft 809. The flattening rubber 810 is located inside the collection box 801.

[0034] In some examples, the circumferential surface of the threaded rod 806 is rotatably connected to a support plate three, the bottom of which is fixedly connected to the top of the base 1. The support plate three is fixed to the base 1, providing an intermediate support point for the threaded rod 806 and reducing radial bending when the length-to-diameter ratio of the threaded rod 806 is large.

[0035] The threaded rod 806 has a thread length equal to the inner wall length of the collection box 801, and the flattening rubber 810 is equal to the inner wall width of the collection box 801. The effective thread length of the threaded rod 806 is equal to the inner wall length of the collection box 801, ensuring that the flattening rubber 810 can cover the entire length of the collection box 801. The width of the flattening rubber 810 is consistent with the inner wall of the collection box 801, eliminating dead corners.

[0036] The diameter of the driving pulley 802 is equal to the diameter of the driven pulley 805, and the side surfaces of the driving pulley 802 and the driven pulley 805 are located on the same parallel plane. The equal diameter design of the driving pulley 802 and the driven pulley 805 ensures consistent rotational speed, prevents slippage of the transmission belt 803, and the coplanar layout reduces lateral offset of the transmission belt 803, extending the service life of the pulleys and the transmission belt 803.

[0037] The side of the collection box 801 contacts the side of the bench vise 6, and the collection box 801 is snapped onto the top of the base 1. The side of the collection box 801 is in close contact with the bench vise 6, ensuring that the metal shavings generated during drilling fall directly into the box, reducing shavings splashing; the snap-fit ​​structure facilitates quick disassembly and cleaning.

[0038] For example, such as Figures 1-5 As shown, the collection device 8 and the cleaning device 7 share a power source. While the rotating shaft 705 drives the rotating wheel 707, its driving pulley 802 on its circumference drives the driven pulley 805 to rotate via the transmission belt 803. The driven pulley 805 is fixed to one end of the threaded rod 806, causing the threaded rod 806 to rotate around the axis of the support plate 804. When the threaded rod 806 rotates, the threaded sleeve 807 reciprocates along the axial direction of the threaded rod 806, driving the rotating shaft 809 and the flattening rubber 810 to slide laterally within the collection box 801 via the transmission rod 808. The width of the flattening rubber 810 is consistent with the inner wall of the collection box 801, and each movement can cover the entire box area, pushing the metal shavings that fall into the box to the designated area.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
