Description

Technical Field

[0001] This utility model relates to the field of lathe technology, and more specifically, to a conventional lathe with an active chip ejection structure. Background Technology

[0002] In existing technologies, debris from conventional lathes is cleaned by repeatedly moving a cleaning brush back and forth, requiring repeated starting and reversing of the motor to move the brush. Chinese Patent Publication No. CN217775592U discloses a chip conveyor device for conventional lathes that automatically moves the cleaning brush back and forth to clean debris from the lathe. Furthermore, the cleaning brush can be automatically lifted during its back-and-forth movement to prevent debris from being swept back onto the lathe platform. This device offers a high degree of automation and improves the efficiency of debris cleaning.

[0003] However, in this patent, the cleaning brush moves horizontally to sweep away debris on the lathe platform, which is inefficient. When there is a lot of debris, it is difficult to clean it in one go. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a conventional vehicle with an active debris ejection structure to solve the above-mentioned shortcomings.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] This utility model discloses a lathe with an active debris ejection structure, comprising a lathe body. The lathe body has a receiving groove on the outer ring of its worktable, which has three sides for receiving ejected debris. A cleaning bracket is movably connected to the receiving groove. A limit plate is provided on the side of the receiving groove facing the moving direction of the cleaning bracket, which restricts the movement position of the cleaning bracket. Rack plates are symmetrically arranged on both sides of the receiving groove perpendicular to the limit plate, serving as the moving track for the cleaning bracket. Support plates are provided at both ends of the cleaning bracket, and drive components are mounted on the support plates. A cleaning brush is movably connected to the cleaning bracket via a guide rod. The drive components include a drive motor, a drive gear, a driven gear, and a roller brush.

[0007] Preferably, the central axis of the roller brush is movably connected to the support plate, and a rotating block is connected to the central axis of the roller brush, with pawls movably connected at equal intervals on the rotating block.

[0008] Preferably, the driven gear has a central groove at its center, which is sleeved with the rotating block. A ratchet is provided on the inner wall of the central groove. When the ratchet engages with the pawl, the driven gear drives the rotating block to rotate synchronously. When the ratchet does not engage with the pawl, the driven gear rotates independently and the roller brush does not rotate.

[0009] Preferably, the output end of the drive motor passes through the support plate, and the output end of the drive motor is fixedly connected to the drive gear. The drive gear meshes with the driven gear, the drive motor drives the drive gear to rotate, and the drive gear meshes with the rack plate.

[0010] Preferably, the driven gear has a smaller diameter than the driving gear. The driven gear is suspended and does not mesh with the rack plate. When the driving gear moves the cleaning bracket to clean, the driven gear rotates faster, increasing the cleaning speed of the lathe worktable. At the same time, the driven gear rotates in the opposite direction to the driving gear, pushing the debris on the lathe worktable towards the receiving groove.

[0011] Preferably, the guide rod is fitted with a support spring. Under the action of the support spring, the cleaning brush contacts the worktable surface of the lathe body, the cleaning bracket moves, and drives the cleaning brush to move horizontally, pushing the debris along the worktable surface.

[0012] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0013] This utility model discloses a conventional lathe with an active chip ejection structure. Through the dual action of a cleaning brush and a roller brush, it can quickly and thoroughly clean chips from the lathe worktable, improving the cleanliness of the machining environment and reducing machining quality problems caused by chip accumulation. When the cleaning support returns, the roller brush stops rotating, and the cleaning brush is carried away from the worktable by an electromagnetic adsorption device, effectively preventing chips from being swept back onto the worktable and keeping the machining area clean. The design of the support plate ensures that the cleaning support can only move along the wall of the receiving groove, avoiding instability or deviation during the cleaning process. Timely chip removal can prevent chips from damaging the cutting tools and workpieces, extending the tool life, while improving machining accuracy and surface quality. The chips are collected in the receiving groove for unified treatment, reducing the risk of environmental pollution. Attached Figure Description

[0019] 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.

[0020] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0021] Combination Figures 1-4 The present invention relates to a lathe with an active debris ejection structure, comprising a lathe body 1, a receiving groove 2 on the outer ring of the worktable surface of the lathe body 1, the receiving groove 2 having three sides for receiving ejected debris, a cleaning bracket 3 movably connected to the receiving groove 2, a limiting plate 21 on the side of the receiving groove 2 facing the moving direction of the cleaning bracket 3, the limiting plate 21 for limiting the moving position of the cleaning bracket 3, and rack plates 22 symmetrically arranged on the two sides of the receiving groove 2 perpendicular to the limiting plate 21, the rack plates 22 serving as the moving track of the cleaning bracket 3.

[0022] Specifically, the cleaning bracket 3 has support plates 31 at both ends, which are movably connected to the wall of the receiving groove 2, preventing the support plates 31 from flipping over and allowing them to move only along the wall of the receiving groove 2. A cleaning brush 33 is movably connected to the cleaning bracket 3 via a guide rod 32, which is fitted with a support spring 34. Under the action of the support spring 34, the cleaning brush 33 contacts the worktable surface of the lathe body 1. The cleaning bracket 3 moves, causing the cleaning brush 33 to move horizontally and push debris along the worktable surface. Furthermore, an electromagnetic adsorption device, including an electromagnet and a magnetic block, is installed on the cleaning brush 33 and the cleaning bracket 3. Its working principle is the same as the electromagnet and magnetic block structure disclosed in Chinese Patent No. CN217775592U, a chip conveyor device for a conventional lathe. When the cleaning bracket 3 returns, the electromagnet and magnetic block carry the cleaning brush 33 away from the worktable surface, preventing debris from being swept back onto the lathe worktable.

[0023] A drive assembly 4 is mounted on the support plate 31. The drive assembly 4 includes a drive motor 41, a drive gear 42, a driven gear 43, and a roller brush 44. The central shaft of the roller brush 44 is movably connected to the support plate 31, and a rotating block 441 is connected to the central shaft of the roller brush 44. Pawls 442 are movably connected at equal intervals on the rotating block 441. Correspondingly, a central groove 431 is formed in the center of the driven gear 43, which is fitted with the rotating block 441. Razor teeth 43 are formed on the inner wall of the central groove 431. 2. When the ratchet 432 engages with the pawl 442, the driven gear 43 drives the rotating block 441 to rotate synchronously. When the ratchet 432 is not engaged with the pawl 442, the driven gear 43 rotates independently and the roller brush 44 does not rotate. When the cleaning bracket 3 pushes the debris, the rotation direction of the ratchet 432 engages with the pawl 442, driving the roller brush 44 to rotate and brush the debris from the lathe worktable. Conversely, when the cleaning bracket 3 returns, the roller brush 44 does not rotate to avoid sweeping the debris back onto the lathe worktable.

[0024] The output end of the drive motor 41 passes through the support plate 31, and the output end of the drive motor 41 is fixedly connected to the drive gear 42. The drive gear 42 meshes with the driven gear 43. The drive motor 41 drives the drive gear 42 to rotate. The drive gear 42 meshes with the rack plate 22. An edge plate is provided on the edge of the rack plate 22. The drive motor 41 is movably connected to the edge plate. When the drive motor 41 works, it drives the drive gear 42 to move along the rack plate 22. The drive motor 41 moves along the edge plate to support the drive motor 41. At the same time, the edge plate limits the drive gear 42 and the driven gear 43. The diameter of the driven gear 43 is smaller than that of the drive gear 42. The driven gear 43 is suspended and does not mesh with the rack plate 22. When the drive gear 42 drives the cleaning bracket 3 to move and clean, the driven gear 43 rotates faster, increasing the cleaning speed of the lathe worktable. At the same time, the driven gear 43 rotates in the opposite direction to the drive gear 42, pushing the debris on the lathe worktable towards the receiving groove 2.

[0025] Working process: After the drive motor 41 starts, the drive gear 42 rotates and meshes with the rack plate 22, thereby driving the cleaning bracket 3 to move horizontally along the wall of the receiving groove 2. The drive motor 41 drives the drive gear 42 to rotate, and the drive gear 42 meshes with the driven gear 43. The driven gear 43 engages with the pawl 442 through the ratchet 432, driving the roller brush 44 to rotate and sweep away the debris on the lathe worktable. The cleaning brush 33 is fixed to the cleaning bracket 3 by the guide rod 32 and the support spring 34, and always remains in contact with the lathe body 1. When the cleaning support 3 moves, the cleaning brush 33 moves horizontally along the worktable surface, pushing the debris into the receiving trough 2. On the return trip, the drive motor 41 rotates in the opposite direction, and the drive gear 42 drives the cleaning support 3 back to the worktable surface. At this time, the ratchet 432 and the pawl 442 disengage, the roller brush 44 stops rotating, and the cleaning brush 33 is attracted upward by the electromagnetic adsorption device. The cleaning brush 33 does not contact the worktable surface, avoiding sweeping the cleaned debris back onto the worktable surface. The pushed debris falls into the receiving trough 2 for subsequent processing.
