Description

Technical Field

[0001] The invention relates to mechanical manufacturing technology, in particular to a waste chip collection and separation system for a machining center. Background Art

[0002] A machining center is a highly automated CNC machine tool that integrates a variety of metal cutting processes such as milling, drilling, boring, tapping, and cutting. It accurately controls the tool's motion trajectory, speed, and feed rate through pre-programmed computer instructions, thereby achieving accurate and efficient processing of complex parts. This machine tool not only has the characteristics of high precision, high stability, and high reliability, but also has extremely high flexibility and can quickly adapt to the processing needs of workpieces of different shapes, sizes, and materials. At the same time, the machining center is also equipped with an automatic tool changing system and tool magazine, so that multiple processes can be completed in one clamping, greatly improving production efficiency and processing quality. Therefore, machining centers have been widely used in aerospace, automobile manufacturing, mold manufacturing, precision parts processing, and other fields.

[0003] When the existing machining center is in use, the metal debris generated by cutting remains inside the device. The waste chips accumulate inside the machine tool and the processing area, which will hinder the normal movement of the tool and cause a decrease in processing accuracy. If the waste chips accumulate inside the machine tool for a long time, they will cause wear or corrosion to the parts of the machine tool and shorten the service life of the machine tool. In addition, the waste chips may also block the chip removal system of the machine tool, causing frequent machine tool failures. Under the existing technology, workers manually clean the waste chips in the machining center, but the sharp parts of the waste chips may scratch the skin or eyes of the operator, and the small space in the machining center makes it inconvenient for workers to clean.

[0068] The cleaning plate 36 is provided with a plurality of teeth.

[0069] The specific implementation is as follows: two waste chip collection plates 2 are symmetrically fixedly installed at the bottom of the inner cavity of the box body 1, and are tilted to facilitate the waste chips to slide to the chip discharge port 5. The chip discharge port 5 is symmetrically opened on one side of the box body 1, located on the lower end side of the waste chip collection plate 2, so as to facilitate the discharge of waste chips. The chip discharge unit 3 is used to push the waste chips located near the chip discharge port 5 out of the box body 1 from the waste chip collection plate 2. Two fixed brackets 31 are symmetrically fixedly installed in the inner cavity of the box body 1, located on one side of the chip discharge port 5. The limiting shaft 32 is arranged at the top of the fixed bracket 31, passes through the fixed bracket 31 and extends to its bottom, and is slidably connected to the fixed bracket 31, and is used to limit the movement range of the turntable 35. The driving source 34 is respectively fixedly installed on the side of the two fixed brackets 31 away from each other to provide power. The power source 34 includes but is not limited to a stepping motor, which is electrically connected to an external power supply and is also controlled by an external PLC programming program. The eccentric wheel 33 is arranged on one side of the fixed bracket 31 close to the driving source 34, and is fixedly connected to the output end of the driving source 34 through a transmission shaft connected by a coupling, and the connection position is far away from the center of the eccentric wheel 33, so that the eccentric wheel 33 generates reciprocating motion when rotating.

[0070] The turntable 35 is rotatably mounted on the outside of the eccentric wheel 33 , with one side of the turntable being located on the outside of the limiting shaft 32 , and can drive the limiting shaft 32 to move along its own axial direction, while the turntable 35 can slide along the outside of the limiting shaft 32 .

[0071] The cleaning plate 36 is fixedly installed between the two rotating disks 35 and is located outside the rotating disks 35 for pushing the waste. The cleaning plate 36 is provided with a plurality of teeth to increase the friction with the waste and improve the pushing effect.

[0072] The waste chip cleaning unit 4 is used to clean the waste chips attached to the waste chip collection plate 2 and push the waste chips on the waste chip collection plate 2 to the chip discharge port 5. The translation drive component 41 is fixedly installed on the side of the inner cavity of the box body 1 away from the chip discharge unit 3 and is located on the top of the waste chip collection plate 2. The translation drive component 41 includes but is not limited to an electric telescopic rod, which is electrically connected to an external power supply and is also controlled by an external PLC programming program.

[0073] The transverse plate 42 is rotatably mounted on the output end of the translation driving member 41 and is used for mounting the telescopic plate 43 and for cleaning the waste on the top of the waste collecting plate 2 .

[0074] The two telescopic plates 43 are symmetrically slidably installed on the inner side of the transverse plate 42 to clean the waste on the waste collecting plate 2 .

[0075] The ear plate 44 is fixedly mounted on one side of the transverse plate 42 close to the translation driving member 41 . The rotating shaft 45 passes through the ear plate 44 and is rotationally connected to the translation driving member 41 to realize the rotation of the transverse plate 42 .

[0076] The return spring 46 is disposed between the translation driving member 41 and the transverse plate 42 and is used to flip the transverse plate 42 when the translation driving member 41 retracts.

[0077] The bidirectional power source 47 is fixedly installed on the inner side of the horizontal plate 42, and its output end is fixedly installed with two threaded rods 48 with opposite thread directions through a coupling. The bidirectional power source 47 includes but is not limited to a double-headed motor which is electrically connected to an external power supply and is controlled by an external PLC programming program.

[0078] The round sleeve 49 is threadedly connected to the threaded rod 48 and slidably installed on the inner side of the horizontal plate 42 to drive the telescopic plate 43 to slide.

[0079] The abutment spring 410 is sleeved on the outside of the circular sleeve 49 , one end of which is fixedly connected to the telescopic plate 43 , and the other end of which is fixedly connected to the circular sleeve 49 , so as to provide buffering when the telescopic plate 43 moves.

[0080] When the waste chips fall on the waste chip collecting plate 2, the translation drive member 41 of the waste chip cleaning unit 4 is started, driving the horizontal plate 42 to translate on the waste chip collecting plate 2. Then the two-way power source 47 is started, driving the two threaded rods 48 to rotate. Due to the opposite directions of the threads, the two circular sleeves 49 move in opposite directions, thereby driving the telescopic plate 43 to slide on the inside of the horizontal plate 42, pushing the waste chips to the chip removal unit 3, and cleaning the waste chips attached to the waste chip collecting plate 2. The circular sleeve 49 can shrink slightly when the telescopic plate 43 is subject to greater external resistance, preventing the iron chips from scratching the inside of the machining center when there are too many or too large iron chips. When the horizontal plate 42 and the telescopic plate 43 have finished cleaning a return stroke, the return spring 46 makes the horizontal plate 42 flip over and not contact the iron chips on the top of the waste chip collecting plate 2.

[0081] The driving source 34 of the chip removal unit 3 is started, driving the eccentric wheel 33 to rotate. The rotation of the eccentric wheel 33 causes the turntable 35 to reciprocate, thereby driving the cleaning plate 36 to slide on the waste chip collection plate 2, pushing the waste chips to the chip removal port 5 for discharge.

[0082] After cleaning is completed, the translation drive member 41 retracts, and the return spring 46 returns the transverse plate 42 to the initial position, waiting for the next cleaning.

[0083] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
