Description

Technical Field

[0001] This utility model relates to the field of CNC lathe technology, specifically to a chip removal structure for a CNC lathe. Background Technology

[0002] During CNC lathe machining, a large amount of metal chips are generated. If these chips are not removed in a timely and effective manner, they will seriously affect the normal operation of the lathe and the machining quality. Currently, most existing CNC lathe chip removal structures use simple chip conveyors for chip removal. These chip conveyors generally use a drive motor to rotate a chain and rollers to remove the chips.

[0003] However, in the existing chip removal structure of CNC lathes, the chip conveyor is prone to clogging during the chip removal process. Because the chips produced during machining vary in shape and size, some chips may become entangled and accumulate, causing the chip removal channel to narrow or even become completely blocked. Once the chip conveyor is blocked, the chips cannot be discharged normally and will accumulate in large quantities inside the chip conveyor. The blockage of the chip conveyor will have an adverse effect on the normal operation of the lathe. If the chips enter the precision components of the lathe, such as the guide rails and lead screws, it will accelerate the wear of the components, reduce the machining accuracy and service life of the lathe. At the same time, in order to clear the blocked chip conveyor, the machining operation of the lathe needs to be stopped, which will lead to the interruption of the machining process, reduce machining efficiency, and increase production costs. Utility Model Content

[0004] The purpose of this utility model is to provide a chip removal structure for a CNC lathe. This chip removal structure solves the problem that during the chip removal process, the chip removal channel becomes narrower or even completely blocked because the chips produced during processing have different shapes and sizes, and some chips may become entangled and accumulate.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A chip removal structure for a CNC lathe includes a chip conveyor, a drive motor fixedly mounted on the top of the chip conveyor, and a roller connected to the output shaft surface of the drive motor via a chain drive. The roller is rotatably connected to the inner side of the chip conveyor. The structure also includes a movable component for clearing blockages of waste material inside the chip conveyor and a rotating component for striking the top of the chip conveyor.

[0007] The movable component includes: a fixed rod, which is fixedly installed on the top of the chip conveyor; a sliding rod is slidably connected to the surface of the fixed rod; a fixed plate is fixedly installed on the bottom of the sliding rod through the chip conveyor; a drive shaft is rotatably connected to the surface of the fixed rod; a rotating shaft is connected to the surface of the drive shaft via a belt drive; a sliding rod is slidably connected to the surface of the rotating shaft; the sliding rod is fixedly installed on the surface of the sliding rod; a connecting rod is fixedly installed on the surface of the sliding rod; and one end of the movable plate is hinged to the bottom of the connecting rod.

[0008] Preferably, the other end of the movable plate is slidably connected to the inner side of the chip conveyor, and a fixing spring is fixedly installed at the bottom of the slide rod, and the fixing spring is fixedly installed at the top of the chip conveyor.

[0009] Preferably, a locking block is slidably connected inside the connecting rod, and the locking block is fixedly installed on the surface of the belt.

[0010] Preferably, the rotating assembly includes: a fixed frame, which is fixedly installed on the top of the chip conveyor; a rotating shaft is rotatably connected to the top of the fixed frame; a reciprocating screw is fixedly installed inside the rotating shaft; an abutting shaft is threadedly connected to the surface of the reciprocating screw; the abutting shaft is slidably connected to the inner side of the fixed frame; and an abutting disc is fixedly installed at the bottom of the abutting shaft.

[0011] Preferably, the chip conveyor has a sliding groove on its surface, a groove inside its interior, and an arc-shaped groove on its surface.

[0012] Preferably, there are two locking blocks, which are respectively located at different ends of the belt surface. The locking blocks move through belt drive and move synchronously towards the center point of the belt.

[0013] Preferably, the cross-section of the fixing frame is U-shaped, and the cross-section of the connecting rod is T-shaped.

[0014] By employing the above technical solution, this utility model provides a chip removal structure for a CNC lathe. It possesses at least the following beneficial effects:

[0015] (1) By setting up the movable components, the blockage of chips accumulates inside the chip conveyor and slides upward against the fixed plate, slide bar and sliding rod. When the slide bar slides upward, it will drive the rotation of the rotating shaft and drive the rotation of the transmission shaft through the belt. When the belt drives, it will drive the locking block to move, so that the bottom connecting rod and movable plate slide inside the chip conveyor, thereby resisting and clearing the blockage inside the chip conveyor, preventing the chip conveyor from failing to work properly due to blockage, affecting chip discharge, causing the lathe processing environment to deteriorate and potentially having an adverse effect on the normal operation of the lathe, improving the continuity and smoothness of chip removal work, extending the service life of the chip conveyor, ensuring the continuity of the overall machining process of the CNC lathe, preventing the processing from being interrupted due to chip removal blockage, and improving processing efficiency.

[0016] (2) By setting up a rotating component, when the rotating shaft rotates, it will also drive the reciprocating screw to rotate. When the reciprocating screw rotates, it will drive the abutting shaft and the abutting plate to slide up and down repeatedly. When the abutting plate slides up and down repeatedly, it will repeatedly knock on the top of the chip conveyor, causing the chip conveyor to vibrate. This prevents the chips at the chip conveyor from adhering to the inner wall of the chip conveyor due to mutual squeezing, sticking, etc., which would cause poor chip removal or even blockage. This improves chip removal efficiency and reduces the frequency of manual cleaning. Attached Figure Description

[0024] 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.

[0025] Example 1

[0026] A chip removal structure for a CNC lathe, such as Figures 1-3 As shown, it includes a chip conveyor 1, a drive motor 2 is fixedly installed on the top of the chip conveyor 1, and a roller 3 is connected to the surface of the output shaft of the drive motor 2 through chain drive. The roller 3 is rotatably connected to the inside of the chip conveyor 1.

[0027] It also includes an active component 4 for clearing the waste material that is blocked inside the chip conveyor 1;

[0028] Rotating component 5 is used to strike the top of chip conveyor 1;

[0029] First, the movable component 4 includes: a fixed rod 41, which is fixedly installed on the top of the chip conveyor 1. A sliding rod 42 is slidably connected to the surface of the fixed rod 41. A fixed plate 43 is fixedly installed at the bottom of the sliding rod 42 through the chip conveyor 1. A drive shaft 44 is rotatably connected to the surface of the fixed rod 41. A rotating shaft 45 is connected to the surface of the drive shaft 44 via a belt drive. A sliding rod 46 is slidably connected to the surface of the rotating shaft 45. The sliding rod 46 is fixedly installed on the surface of the sliding rod 42. A connecting rod 47 is fixedly installed on the surface of the sliding rod 46. One end of a movable plate 48 is hinged to the bottom of the connecting rod 47. One end of the movable plate 48 is hinged to the bottom of the connecting rod 47, and the other end is slidably connected to the inside of the chip conveyor 1. This allows the connecting rod 47 to slide upward, pulling one end of the movable plate 48 to swing upward and into a vertical position.

[0030] Secondly, the other end of the movable plate 48 is slidably connected to the inner side of the chip conveyor 1. A fixed spring 49 is fixedly installed at the bottom of the slide rod 42. The fixed spring 49 is fixedly installed at the top of the chip conveyor 1. The fixed spring 49 on the surface of the slide rod 42 can achieve the effect of resetting after the slide rod 42 has finished sliding.

[0031] Furthermore, a locking block 410 is slidably connected inside the connecting rod 47. The locking block 410 is fixedly installed on the surface of the belt. The locking block 410 on the surface of the connecting rod 47 can be used to simultaneously drive the connecting rod 47 to slide inside the locking block 410 when the locking block 410 slides.

[0032] In this embodiment, through the setting of the movable component 4, the clogged debris accumulates inside the chip conveyor 1 and slides upward against the fixed plate 43, the slide rod 42, and the sliding rod 46. When the slide rod 42 slides upward, it drives the rotating shaft 45 to rotate, and drives the transmission shaft 44 to rotate through the belt. When the belt drives, it drives the locking block 410 to move, so that the bottom connecting rod 47 and the movable plate 48 slide inside the chip conveyor 1, thereby clearing the blockage inside the chip conveyor 1, preventing the chip conveyor 1 from failing to work properly due to blockage, affecting the discharge of debris, causing a deterioration of the lathe machining environment, and potentially having an adverse effect on the normal operation of the lathe. This improves the continuity and smoothness of the chip removal work, extends the service life of the chip conveyor 1, ensures the continuity of the overall machining process of the CNC lathe, prevents the machining from being interrupted due to the blockage of the chip removal link, and improves the machining efficiency.

[0033] Example 2

[0034] like Figures 4-5 As shown, the rotating assembly 5 includes: a fixed frame 51, which is fixedly installed on the top of the chip conveyor 1; a rotating shaft 45 is rotatably connected to the top of the fixed frame 51; a reciprocating screw 52 is fixedly installed inside the rotating shaft 45; an abutting shaft 53 is threadedly connected to the surface of the reciprocating screw 52; the abutting shaft 53 is slidably connected to the inner side of the fixed frame 51; and an abutting disc 54 is fixedly installed at the bottom of the abutting shaft 53.

[0035] Finally, a groove 10 is provided on the surface of the chip conveyor 1, through which the connecting rod 47 passes through the chip conveyor 1. A groove 11 is provided inside the chip conveyor 1, through which one end of the movable plate 48 can slide inside the chip conveyor 1. An arc groove 450 is provided on the surface of the rotating shaft 45, through which the rotating shaft 45 can rotate when the sliding rod 46 slides. Two locking blocks 410 are provided, and the two locking blocks 410 are respectively located at different ends of the belt surface. The locking blocks 410 move through the belt drive and move synchronously towards the center point of the belt. The cross-section of the fixing frame 51 is U-shaped and the cross-section of the connecting rod 47 is T-shaped. The U-shaped fixing frame 51 and the T-shaped connecting rod 47 can improve the connection effect between the fixing frame 51 and the chip conveyor 1, as well as the connection effect between the connecting rod 47 and the locking blocks 410.

[0036] In this embodiment, by setting the rotating component 5, when the rotating shaft 45 rotates, it will also drive the reciprocating screw 52 to rotate. When the reciprocating screw 52 rotates, it will drive the abutting shaft 53 and the abutting disk 54 to slide up and down repeatedly. When the abutting disk 54 slides up and down repeatedly, it will repeatedly knock on the top of the chip conveyor 1, causing the chip conveyor 1 to vibrate. This prevents the chips at the chip conveyor 1 from adhering to the inner wall of the chip conveyor due to mutual compression, adhesion, etc., which would cause poor chip removal or even blockage. This improves chip removal efficiency and reduces the frequency of manual cleaning.

[0037] In use, the chip removal structure of this CNC lathe allows chips to be fed into the chip conveyor 1. The drive motor 2 is then activated, driving the roller 3 via a chain to remove the chips. If blockage occurs during chip removal, the blocked chips stop discharging and accumulate inside the chip conveyor 1, sliding upwards against the fixed plate 43. This upward sliding of the fixed plate 43 causes the sliding rod 42 to slide upwards, which in turn causes the sliding rod 46 to slide at the arc-shaped groove 450 on the surface of the rotating shaft 45, thus rotating the rotating shaft 45. The rotation of the rotating shaft 45 then drives the transmission shaft 44 via a belt. This belt drive causes the locking block 410 to shift in the same direction as the belt drive. When the locking block 410 moves, it drives the connecting rod 47 and the movable plate 48 at the bottom to slide inside the chip conveyor 1. When the sliding rod 46 slides upward, it also pulls the connecting rod 47 to slide upward on the surface of the locking block 410, thereby pulling one end of the movable plate 48 to swing upward and slide vertically inside the chip conveyor 1. This helps to clear blockages inside the chip conveyor 1, preventing it from malfunctioning due to blockage, affecting chip discharge, deteriorating the lathe machining environment, and potentially adversely affecting the normal operation of the lathe. This improves the continuity and smoothness of chip removal, extends the service life of the chip conveyor 1, ensures the continuity of the overall machining process of the CNC lathe, prevents machining from being interrupted due to blockage in the chip removal process, and improves machining efficiency.

[0038] When the rotating shaft 45 rotates under the sliding action of the sliding rod 46, it will also drive the reciprocating screw 52 inside the rotating shaft 45 to rotate. When the reciprocating screw 52 rotates, it will drive the abutment shaft 53 to slide downward inside the fixed frame 51. When the abutment shaft 53 slides up and down inside the rotating shaft 45, it will drive the abutment plate 54 to slide up and down. When the abutment plate 54 slides up and down, it will repeatedly knock on the top of the chip conveyor 1, causing the chip discharge point of the chip conveyor 1 to vibrate. This prevents the chips at the chip discharge point of the chip conveyor 1 from adhering to the inner wall of the chip discharge point due to mutual compression, adhesion, etc., which would cause poor chip discharge or even blockage. This improves the chip discharge efficiency and reduces the frequency of manual cleaning.
