Description

Technical Field

[0001] The utility model belongs to the technical field of machining centers, and particularly relates to an auxiliary chip removal device for a machining center. Background Art

[0002] A machining center is a CNC machining equipment with a high degree of automation and high machining precision. It is widely used in mechanical cutting. When machining parts, the machining center will produce waste. In order not to affect the processing, the waste needs to be cleaned up in time.

[0003] To remove waste during machining, machining centers currently feature two sets of chip chutes, extending forward and backward, angled on either side of the worktable. These chutes utilize gravity to collect the waste in a waste bin. However, in practice, for various reasons, a significant amount of waste can remain in the chutes and remain undischarged. After machining is complete, the chutes must be cleared to maintain a clean environment for the machining center.

[0004] The existing technology uses a motor or cylinder to drive the scraper to move back and forth in the chip chute to replace the traditional manual removal of waste in the chip chute, thereby reducing the labor intensity of employees. However, there are the following problems: in order for the scraper to move smoothly in the chip chute, there is still a certain gap between the scraper and the inner wall of the chip chute. When the scraper is pushed back and forth in the chip chute for cleaning, a large amount of fine waste chips will still remain in the chip chute and cannot be discharged, resulting in poor cleaning effect. After cleaning, manual cleaning with a brush or air gun is still required for multiple times to be cleaned. Utility Model Content

DETAILED DESCRIPTION

[0026] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0027] See also Figure 1 and Figure 2 In one embodiment, an auxiliary chip removal device for a machining center includes: a chip removal groove 2, a cleaning component 3 and a driving component 4.

[0028] In one embodiment, the chip removal groove 2 is provided on the machining center equipment 1 .

[0029] The machining center equipment 1 is provided with a base 11 on which a worktable 12 is mounted that can move forward and backward. A chip removal groove 2 is provided at the upper end of the base 11 and on the left and right sides of the worktable 12 . The chip removal groove 2 extends along the front and back direction of the base 11 .

[0030] Preferably, the width of the chip flute 2 from the slot opening to the bottom of the slot gradually decreases, so that the side inner wall of the chip flute 2 is tilted downward. This structure can make the waste chips gather to the bottom of the chip flute 2 under the action of gravity during the processing. A chip discharge port 21 is provided at the end of the chip flute 2. The chip discharge port 21 is used to discharge the waste chips accumulated in the chip flute 2. The chip discharge port 21 is connected to the external chip removal device 6. Preferably, the bottom of the chip flute 2 is tilted and extends obliquely to the chip discharge port 21. This structure can make the waste chips in the chip flute 2 enter the chip removal device 6 through the chip discharge port 21 under the action of gravity. Preferably, in order to maintain efficient automatic chip removal, the chip removal device 6 adopts the existing machine tool spiral chip removal device.

[0031] In one embodiment, the driving assembly 4 is installed in the machining center 1, and the cleaning assembly 3 is installed on the driving assembly 4. The driving assembly 4 is used to drive the cleaning assembly 3 to move in the chip chute 2 to clean the waste chips accumulated in the chip chute 2.

[0032] Specifically, the driving assembly 4 includes a driving source 41, a screw 42 and a nut 43. The driving source 41 is installed on the outer wall of the machining center equipment 1. Preferably, the driving source 41 is a servo motor. The screw 42 is installed at the output end of the servo motor and is rotatably installed in the chip groove 2. The nut 43 is threadedly connected to the screw 42, and the cleaning assembly 3 is connected to the nut 43. Preferably, the driving source 41 and the screw 42 are arranged parallel to the bottom of the chip groove 2, so that the cleaning assembly 3 is parallel to the bottom of the chip groove 2. When in use, the servo motor is started, and the servo motor drives the screw 42 to rotate, thereby realizing the movement of the cleaning assembly 3 in the chip groove 2.

[0033] In one embodiment, the cleaning assembly 3 is installed in the chip flute 2 and includes a scraper 31 fixedly mounted on the outer surface of the nut 43. The scraper 31 is provided with a chip suction chamber 311, which is connected to an external dust collection device 5 via an air pipe 51. Preferably, the dust collection device 5 is an industrial negative pressure vacuum cleaner. A plurality of slots are provided at intervals along the circumference of the scraper 31, communicating with the chip suction chamber 311. The slots are opposed to the inner wall of the chip flute 2.

[0034] In the process of the scraper 31 moving in the chip groove 2, starting the dust suction device 5 can generate negative pressure in the chip suction chamber 311, thereby sucking the waste chips adhering to the inner wall of the chip groove 2 into the chip suction chamber 311, and then sucking them into the dust suction device 5, thereby removing the waste chips adhering to the chip groove 2.

[0035] In one embodiment, a brush 32 is provided on a side wall of the scraper 31 opposite to the inner wall of the chip flute 2 , and the brush 32 abuts against the inner wall of the chip flute 2 .

[0036] On the basis of the above embodiment, the scraper 31 is provided with a scraper cover 33, which is mounted on the outside of the scraper 31 and has an opening 331 for exposing the hole groove. The brush 32 is arranged on the scraper cover 33. The scraper cover 33 protects the scraper 31 and is easy to replace.

[0037] On the basis of the above embodiment, the cleaning component 3 further includes a suction nozzle 34 . The suction nozzle 34 is installed in the hole groove and passes through the scraper cover 33 . The height of the suction nozzle 34 is slightly lower than the height of the brush 32 .

[0038] In one embodiment, during the machining process of the machining center, coolant needs to be sprayed to cool the tool and workpiece. The coolant mixed with the waste chips enters the chip groove 2. Therefore, the waste chips adhering to the chip groove 2 are generally wet. After the brush 32 brushes the inner wall of the chip groove 2, the waste chips are very likely to adhere to the brush 32. When the brush 32 is pushed again, the waste chips adhering to the brush 32 will fall into the chip groove 2, reducing the cleaning effect.

[0039] Therefore, further, the cleaning component 3 is also provided with a plurality of air nozzles 35, and the air nozzles 35 are arranged at intervals along the circumference of the scraper 31. The scraper 31 is provided with a blowing chamber 312; the air nozzle 35 is connected to the blowing chamber 312, the air nozzle 35 passes through the outside of the scraper cover 33, and is arranged in the brush 32. The blowing chamber 312 is not connected to the chip suction chamber 311, and the height of the air nozzle 35 is lower than the height of the brush 32. An air pump is provided on or outside the machining center equipment 1, and the air pump is connected to the blowing chamber 312 through an extension tube 36. When the scraper 31 is located at the chip discharge port 21, the air pump is started, and the air flow ejected from the air nozzle 35 will blow off the waste chips adhering to the brush 32, thereby improving the effect of the brush 32 in removing the waste chips in the chip discharge groove 2 next time.

[0040] Based on the above embodiment, the brush 32 includes a brush body 322 and a rubber ball 321, which is arranged at the top of the brush body 322. The rubber ball 321 can avoid scratching the inner wall of the chip groove 2 to prevent chips from sticking to the scratches and being difficult to remove.

[0041] During specific operation, the scraper 31 is first positioned at one end of the chip flute 2 away from the chip discharge port 21. After the workpiece is processed, the servo motor is started, which drives the screw 42 to rotate, so that the scraper 31 and the brush 32 move along the chip flute 2 toward the chip discharge port 21, cleaning most of the waste chips in the chip flute 2 into the chip discharge device 6. When the scraper 31 reaches the chip discharge port 21, the air pump is started, and the air flow from the air nozzle 35 is blown toward the brush 32, blowing the debris adhering to the brush 32 into the chip discharge device 6. The air pump is turned off, the servo motor is rotated in the opposite direction, and the industrial negative pressure vacuum cleaner is turned on at the same time. The scraper 31 moves away from the chip discharge port 21, and the brush 32 moves while the debris is pushed from the suction nozzle 34 into the chip suction chamber 311, and then enters the industrial negative pressure vacuum cleaner through the air pipe 51. By combining the above methods, the servo motor rotates forward and reverse, driving the scraper 31 to move back and forth, and the debris in the chip groove 2 can be cleaned in fewer times, and the cleaning is thorough, without the need for workers to clean it again.

[0042] Beneficial effects of the utility model:

[0043] The above-mentioned auxiliary chip removal device for a machining center is provided with a chip trough 2, a cleaning component 3 and a driving component 4 in the machining center equipment 1. The cleaning component 3 is provided with a scraper 31 and a brush 32 of a chip suction chamber 311. The chip suction chamber 311 is connected to an external dust suction device 5. The brush 32 is driven by the driving component 4 to move in the chip trough 2, thereby brushing off the debris on the inner wall of the chip trough 2. The debris in the chip trough 2 can also be sucked out by the external dust suction device 5, thereby completely removing the debris in the chip trough 2. The worker does not need to clean the chip trough 2 again, thereby improving work efficiency. In addition, by providing an air nozzle 35, the debris adhering to the brush 32 is blown off, and the chip trough 2 debris can be cleaned thoroughly with fewer times. A scraper cover 33 is provided. When the brush 32 is damaged or skewed and is not conducive to brushing, the scraper cover 33 can be quickly replaced without replacing the entire cleaning component 3, thereby saving cost and time.
