[0025] 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.

[0026] Reference Figure 1 - Figure 3This utility model provides an embodiment of an automatic chip removal device for CNC lathes, comprising a housing 1, with an inlet 2 on the upper surface of the housing 1 for introducing machine chips from the machine through a pipe into the housing 1. A motor 3 is fixedly connected to the front surface of the housing 1, serving as the power source for the mechanical operation within the housing 1. A discharge box 4 is detachably installed at the bottom of the housing 1 for collecting the chip powder generated within the housing 1, thus improving the convenience of chip removal for operators. The output shaft of the motor 3 is fixedly connected to a rotating shaft 5. An auxiliary component 10 is provided on the outer surface of the shaft 5. The auxiliary component 10 includes a crushing roller 101, which is fixedly connected to the outer arc surface of the outer wall of the rotating shaft 5. The crushing roller 101 crushes the debris in the housing 1, improving the debris removal efficiency. A strip groove 102 is formed on the outer wall of the crushing roller 101. The crushing roller 101 rotates under the action of the rotating shaft 5. When the crushing roller 101 moves to one side of the magnetic strip 9 during rotation, the cross-sectional area of ​​the groove 102 and the magnetic strip... The cross-sectional areas of the magnetic plates 105 are mutually compatible. The magnetic plate 105 is slidably connected inside the strip groove 102. Because the magnetic poles of the magnetic strip 9 and the magnetic plate 105 are opposite magnetic poles, a large magnetic force is generated between the magnetic plate 105 and the magnetic strip 9 when the distance between them is small. A telescopic rod 103 is fixedly connected to the bottom of the inner wall of the strip groove 102. A spring 104 is sleeved on the outer wall of the telescopic end of the telescopic rod 103. The bottom end of the spring 104 is fixedly connected to the upper surface of the telescopic end of the telescopic rod 103, and the top end of the spring 104 is fixedly connected to the lower surface of the magnetic plate 105. The magnetic force causes the magnetic strip 9 to work with the magnetic plate 105 to overcome the elastic force of the spring 104 and push out of the strip groove 102, thereby cleaning the outer surface of the crushing roller 101. The top of the telescopic rod 103 is fixedly connected to the magnetic plate 105 to prevent the crushed powder from accumulating on the outer surface of the crushing roller 101, which would weaken the crushing effect of the crushing roller 101. This improves the cleanliness of the crushing roller 101 during long-term operation, makes the lathe chips more malleable, and improves the convenience of lathe chip collection for workers.

[0027] Reference Figure 1 - Figure 3A drive device 6 is installed on the inner wall of the housing 1 near the inner side of the rotating shaft 5. During the operation of the crushing roller 101, the drive device 6 is activated. The drive device 6 includes a drive box 64, which is fixedly connected to the front surface of the inner wall of the housing 1. A half gear 61 is fixedly connected to the outer wall of the rotating shaft 5 near the drive box 64. Racks are provided on both sides of the inner wall of the movable block 63. The gear edge of the half gear 61 meshes with the teeth of the rack, causing the rotating shaft 5 to rotate and drive the half gear 61 to rotate. The movable block 63 is slidably connected to the inner wall of the drive box 64. Through the rotation of the half gear 61 and the movable block 63, the reciprocating motion of the push rod 62 in the vertical direction is realized. The push rod 62 is fixedly connected to the bottom of the movable block 63. A rocking assembly 7 is provided on the left end of the inner wall of the housing 1. The rocking assembly 7 includes a frame 74. The frame 74 is fixedly connected to the drive box 63. The pressure block 72 is fixedly connected to the left end of the inner wall of the housing 1. The right surface of the pressure block 72 is set as an inclined surface. The reciprocating motion of the push rod 62 in the vertical direction cooperates with the pressure block 72 to move the pressure block 72 inward, driving the filter screen 71 to move. The filter screen 71 is slidably connected to the inner wall of the frame 74. The right end of the filter screen 71 is fixedly connected to the pressure block 72. The elastic rod 73 is deformed by varying degrees of compression, causing the filter screen 71 to shake in the frame 74. The left end of the filter screen 71 is fixedly connected to the elastic rod 73. The upper surface of the filter screen 71 is provided with several groups of evenly distributed small through holes. Because the filter screen 71 shakes in the horizontal direction, the left end of the elastic rod 73 is fixedly connected to the inner wall of the frame 74, which prevents the filter screen 71 from clogging after long-term operation and improves the service life of the filter screen 71.

[0028] Reference Figure 1 - Figure 3 During the operation of the crushing roller 101, the turning device 8 is activated. The turning device 8 is fixedly connected to the inner surface of the casing 1. The turning device 8 includes a turning chamber 82, which is fixedly connected to the right end of the inner wall of the casing 1. Large lathe debris, after being acted upon by the crushing roller 101, falls into the turning chamber 82 through the filter screen 71. A discharge channel 81 is fixedly connected to the upper left side of the outer wall of the turning chamber 82, so that the turning chamber 82 discharges the large lathe debris back into the crushing roller 101 through the discharge channel 81. A magnetic strip 9 is fixedly connected to the lower side of the outer wall of the turning chamber 82 near the discharge channel 81, forming a cyclic crushing effect on the large lathe debris, which enhances the chip removal effect of the casing 1 on the lathe debris.

[0029] Working Principle: The machine tool debris is fed into the housing 1 through the feed inlet 2 via a pipe. The auxiliary component 10 is activated, and the crushing roller 101 rotates under the action of the rotating shaft 5. When the crushing roller 101 moves to the side of the magnetic strip 9 during rotation, the cross-sectional area of ​​the groove in the strip groove 102 matches the cross-sectional area of ​​the magnetic plate 105. The magnetic plate 105 is slidably connected inside the strip groove 102. Because the magnetic poles of the magnetic strip 9 and the magnetic plate 105 are opposite poles, a large magnetic force is generated when the distance between the magnetic plate 105 and the magnetic strip 9 is small. Through this magnetic force, the magnetic strip 9, in conjunction with the magnetic plate 105, overcomes the elastic force of the spring 104 and performs a pushing motion in the strip groove 102. This cleans the outer surface of the crushing roller 101, preventing the accumulation of crushed powder on its outer surface and thus reducing the crushing effect of the crushing roller 101. This improves the cleanliness of the crushing roller 101 during long-term operation, gives the lathe debris better plasticity, and enhances the operator's ability to handle lathe debris effectively. For ease of collection, racks are provided on both sides of the inner wall of the movable block 63. The gear edge of the half gear 61 meshes with the teeth of the rack, causing the rotating shaft 5 to rotate and drive the half gear 61 to rotate. Through the rotation of the half gear 61 and the movable block 63, the push rod 62 reciprocates vertically. The elastic rod 73 is deformed by varying degrees of compression, causing the filter screen 71 to sway within the frame 74. The upper surface of the filter screen 71 is provided with several sets of evenly distributed fine through holes. Because the filter screen 71 is horizontal... The shaking motion prevents the filter screen 71 from clogging after prolonged operation, thus extending its service life. During the operation of the crushing roller 101, the activation of the tilting device 8 causes large lathe debris, after being acted upon by the crushing roller 101, to fall into the tilting chamber 82 through the filter screen 71. The tilting chamber 82 then discharges the large lathe debris back into the crushing roller 101 through the discharge channel 81, forming a cyclic crushing effect on the large lathe debris and enhancing the chip removal effect of the casing 1.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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.
