Description

Technical Field

[0001] The invention relates to the field of numerically controlled gantry milling machines, in particular to a chip removal device of a fixed-beam numerically controlled gantry milling machine. Background Art

[0002] The gantry milling machine consists of a gantry frame, a bed workbench and an electrical control system. The gantry frame consists of columns and a top beam, with a crossbeam in the middle. There are 1 to 2 milling heads with vertical spindles on the crossbeam, which can move horizontally along the crossbeam guide rail. A milling head with a horizontal spindle can also be installed on each of the two columns, which can move up and down along the column guide rail. During processing, the workpiece is mounted on the workbench and moves longitudinally. There is a chip removal mechanism on the workbench, while the general chip removal mechanism only directly sets a slot for holding chips on the workbench, and then opens a hole at one end of the slot to remove the chips in the slot. The chips are cleaned by manual operation, which greatly increases the labor intensity of the operator and also affects the use progress of the milling machine.

[0003] In the prior art, the debris in the chip groove of the milling machine is mostly cleaned and pushed out by a mechanical structure. Conventional mechanical mechanisms such as a push plate or an auger rod are prone to push the debris out, and the debris is easily higher than the T-slot due to the debris clumping, and is left on the milling table surface. The plane of the milling machine needs to be cleaned manually. In addition, the scattered debris is directly pushed out, generally through a conveyor. However, during the pushing process, the debris is easy to fall to the ground, causing the environment around the milling machine to be dirty and messy, and the efficiency of cleaning the debris of the milling machine is low, and the cleaning effect is also poor.

At the same time, the soft belt can prevent debris from remaining on the flat end of the milling table. The compression component is used to compress the debris into blocks inside the compression chamber and send it out in agglomeration.

The driving gears 419 at both ends of the brush roller 44 mesh with the toothed plate 418 to drive the brush roller 44 to rotate, and the debris remaining on the inclined surface of the T-slot 13 is cleaned and dropped into the lower compression chamber. At the same time, the rotation of the bidirectional screw rod 47 drives the second winding seat 48 to rotate, and the second pull rope 410 and the first spring 49 control the triangular plate 42 and the top column 43 to move up and down. When the brush roller 44 moves upward, the triangular plate 42 and the top column 43 move downward, and the debris accumulated in the middle position of the T-slot 13 is squeezed into the compression chamber. At the same time, when the brush roller 44 moves downward, the triangular plate 42 and the top column 43 move upward, which facilitates the debris to enter the compression chamber through the hollow position in the middle of the T-slot 13. During the movement of the slider 412, the third pull rope 415 pulls the soft belt 416 to move.The debris remaining on the plane of the milling table 11 is scraped into the inside of the T-slot 13, and then the soft belt 416 is reset by the second spring 417. The soft belt 416 and the third pull rope 415 are both made of soft materials and will not cause a significant impact on the processed object.

[0034] When the T-slot 13 of the milling table 11 needs to be cleaned, the second motor 51 drives the cross plate roller 5 to rotate, thereby receiving the debris dropped in the middle of the T-slot 13, and the debris falls between the two groups of single plates of the cross plate roller 5, and as the cross plate roller 5 rotates, the debris is sprinkled inside the compression chamber along the path, and the first bevel gear 420 is meshed with the second bevel gear 421 through the transmission of the transmission belt 41, and the bidirectional screw rod 47 rotates, and the two moving blocks 413 are meshed with the bidirectional screw rod 47 and slide along the transverse groove 46, thereby driving the spring telescopic plate 414 to pull the slider 412 to move along the slide rail.

At the same time, the rotation of the bidirectional screw rod 47 drives the second winding seat 48 to rotate, and the second pull rope 410 and the first spring 49 control the triangular plate 42 and the top column 43 to move up and down. When the brush roller 44 moves upward, the triangular plate 42 and the top column 43 move downward, and the debris accumulated in the middle position of the T-slot 13 is squeezed into the compression chamber. At the same time, when the brush roller 44 moves downward, the triangular plate 42 and the top column 43 move downward.

During the movement of the slider 412, the third pull rope 415 pulls the soft belt 416 to move, and the debris remaining on the plane of the milling table 11 is scraped into the inside of the T-slot 13. Then the soft belt 416 is reset by the second spring 417, and the electric push rod 31 drives the connecting frame 32 to move, so that the upper baffle 33 and the lower baffle 34 can be inserted into or pulled out of the compression chamber. When the debris in the compression chamber needs to be compressed, the upper baffle 33 and the lower baffle 34 are sent in. At this time, the lower baffle 34 blocks the delivery outlet 14, and the first motor 36 drives the first winding seat 35 on one side of the milling table 11 to reel in the first pull rope 37, and the first winding seat 35 on the other side to unwind the first pull rope 37, so that the pressure plate 38 moves along the inside of the compression chamber and enters between the upper baffle 33 and the lower baffle 34 to compress the debris into blocks.
