Description

Technical Field

[0001] The utility model particularly relates to a chip removal device for a numerically controlled machine tool. Background Art

[0002] CNC machine tools generate large quantities of cutting chips during machining. These chips come in a variety of shapes and sizes, including rolls, balls, strips, blocks, and granules. Production lines utilize continuous flow operations, generating significant amounts of chips. Especially during the roughing stage, these chips appear as fragments or powder, easily scattering. Failure to promptly clean these chips can severely impact machining progress. Currently, manual cleaning is the primary method, resulting in slow, incomplete, and inefficient cleaning, which in turn impacts machining efficiency.

[0003] To solve the above problems, the existing Chinese patent announcement number CN205057651U discloses an automatic chip conveyor for machine tools, which discloses a frame, and a motor, a transmission assembly and a conveyor chain plate installed on the frame. The motor drives the transmission assembly to operate, and the transmission assembly drives the conveyor chain plate to operate. The frame includes a horizontal part and a slope part. The tail end of the slope part is provided with a discharge port, and the bottom of the slope part is provided with a support foot.

[0004] In summary, although the existing chain plate type chip conveyor realizes automatic chip removal of waste materials, it does not have the function of screening and separating the cutting coolant and the cutting waste materials after chip removal, which makes it inconvenient to recycle the cutting coolant.

[0023] Specifically, a filter hopper is provided at the discharge port of the chain plate type chip conveyor, and the first filter screen and the second filter screen are combined in the filter hopper to realize the secondary filtration of the cutting waste in sequence, that is, the cutting waste falls from the discharge port of the chain plate type chip conveyor to the first filter screen, and after being filtered by the first filter screen, the cutting coolant after screening and separation falls onto the guide plate, and then is guided by the guide plate to flow through the second filter screen to realize secondary filtration, thereby effectively realizing the screening and separation of the cutting coolant and the cutting waste, and then the first driving component is used to drive the filter hopper to flip over to effectively dump the cutting waste after screening and separation.

[0024] Furthermore, one end of the first filter screen 35 is rotatably arranged in the upper filter area 33 through a rotating shaft 38, and the second filter screen 36 is movably arranged in the upper filter area 33, and the length direction of the second filter screen 36 is set at an inclined angle to the length direction of the first filter screen 35. The first filter screen 35, the second filter screen 36 and the guide plate 32 form a second filter area 37. A second driving component 5 is provided on one side of the material box 31 to drive the first filter screen 35 to swing back and forth, and a connecting rod 6 is hinged between the first filter screen 35 and the second filter screen 36.

[0025] Specifically, the first filter screen is driven to swing back and forth up and down by the second driving component to effectively vibrate and screen the waste material stagnant on the first filter screen, and the connecting rod is used to transmit the first filter screen back and forth, while driving the second filter screen to move up and down relative to the guide plate, thereby facilitating the waste material located on the guide plate to be filtered through the filter holes of different heights of the second filter screen, thereby effectively avoiding the disadvantage of poor filtering effect caused by clogging of the filter holes of the second filter screen.

[0026] Furthermore, the second driving member 5 includes a motor 61 disposed outside the material box 31 and a cam 62 disposed on the drive shaft of the motor 61. One end of the rotating shaft 38 extends to the outside of the material box 31 and is provided with a connecting plate 63. The contour edge of the cam 62 abuts the underside of the connecting plate 63. Specifically, the motor drives the cam to rotate, causing the contour edge of the cam to swing up and down as it rotates and abuts the connecting plate, thereby driving the first filter to swing back and forth via the rotating shaft.

[0027] Furthermore, a flange 64 is provided at one end of the first filter screen 35 , and the flange 64 moves with the first filter screen 35 to abut against one side of the second filter screen 36 , and an elastically deformable sealing gasket is provided between the flange 64 and the second filter screen 36 .

[0028] Furthermore, a discharge port 11 is formed through one side of the upper filtering area 33.

A rotary cylinder 13 capable of turning the cover plate 12 is provided on one side of the material box 31. The rotary cylinder is then used to open or close the cover plate relative to the discharge port. The cover plate is closed during filtration and opened when waste material on the first filter screen and the guide plate needs to be dumped.

[0029] Furthermore, a guide shaft 14 is rotatably provided at one end of the guide plate 32 in the material box 31, and the second filter 36 is movably inserted between the guide shaft 14 and the guide plate 32. The up and down movement of the second filter relative to the guide plate effectively avoids the problem of poor filtering effect caused by clogging of the second filter.

[0030] Furthermore, the first driving member 4 includes a first hinge seat 41, a second hinge seat 42, and a hydraulic rod 43. The first hinge seat 41 is hinged to one side of the chain-plate chip conveyor 1. The hydraulic rod 43 is disposed on the first hinge seat 41. The second hinge seat 42 is disposed at the driving end of the hydraulic rod 43. The second hinge seat 42 is hinged to the filter hopper 3. Specifically, the combination of the first and second hinge seats and the hydraulic rod enables the hydraulic rod to retract and retract, thereby driving the filter hopper to flip relative to the chain-plate chip conveyor, thereby automatically dumping the accumulated cutting waste in the filter hopper.

[0031] Furthermore, a limiting rod 99 capable of limiting contact with the upper side of the first filter screen 35 is provided in the material box 31. The limiting rod is then used to limit the space for the first filter screen to swing upward.
