The present application is described in further detail below with reference to figures 1-5.

The embodiment of the application discloses milling cutter formula board separator.

Referring to fig. 1 and 2, the table comprises a table top 1 and a processing platform 2; a dust collecting opening 11 is formed in the table top 1, and a dust collector is communicated below the dust collecting opening 11; the processing platform 2 clamps the workpiece 21 and drives the workpiece 21 to feed or withdraw above the table board 1; a backing plate 3 is arranged on the upper side of the table board 1, a dust channel 31 is arranged on the backing plate 3, and the dust channel 31 penetrates through the upper side and the lower side of the backing plate 3 and is communicated with the dust collecting port 11; an air gap 12 meeting the requirement exists between the processing platform 2 and the backing plate 3, so that the air suction flow of the dust collector is converged at the position where the workpiece 21 is processed.

In addition, referring to fig. 1, the milling cutter type plate separator further includes a supporting cabinet 4 and a milling cutter 5, and an electrical structure required for the operation of the milling cutter type plate separator is accommodated in the supporting cabinet 4. The table board 1 is rectangular plate-shaped and is detachably connected with the upper side of the supporting cabinet 4. The milling cutter 5 is movably arranged above the machine tool, and the milling cutter 5 is driven by a main shaft of the milling cutter type plate separator to move along a designated path to machine a workpiece 21.

In the application, the staff loads the work piece 21 of treating processing on processing platform 2 earlier, then processing platform 2 drives work piece 21 and feeds to the assigned position, and milling cutter 5 processes work piece 21, and the dust collector starts to absorb the piece and the dust that produce processing simultaneously, and piece and dust get into the dust collector through dirt bits passageway 31 and dust collection mouth 11, and processing platform 2 drives work piece 21 and withdraws from the assigned position after finishing.

The air gap 12 needs to satisfy the following conditions: the air flow sucked by the dust collector can be converged, and the feeding and the withdrawing of the processing platform 2 are not obstructed.

When the base plate 3 is not arranged on the table top 1, the suction air flow of the dust collector sucks the chips at the processing position 211 of the workpiece 21 through the dust collecting port 11, and the suction air flow of the dust collector is not concentrated and the sucking effect of the chips is not good because the gap between the processing platform 2 and the base plate 3 is large. In the invention, the backing plate 3 is arranged between the table board 1 and the processing platform 2, the backing plate 3 reduces the gap between the processing platform 2 and the table board 1, the suction air flow of the dust collector is not easy to diffuse through the gap between the backing plate 3 and the processing platform 2, and the dust channel 31 on the backing plate 3 also has a function of converging the suction air flow of the dust collector, so that the effect of the dust collector on absorbing the chips is well improved.

Referring to fig. 1 and 3, the backing plate 3 has a guide slope 32, the guide slope 32 is located on the side of the backing plate 3 upstream in the feeding direction of the workpiece 21, and the guide slope 32 is inclined upward in the feeding direction of the processing platform 2.

Specifically, the guiding inclined plane 32 inclines upwards along the feeding direction of the processing platform 2, on one hand, the guiding inclined plane 32 can guide the processing platform 2 to move above the backing plate 3, and on the other hand, compared with the backing plate 3 without the guiding inclined plane 32, the backing plate 3 with the guiding inclined plane 32 is not damaged when colliding with the processing platform 2, so that the height of the processing platform 2 is set to have a certain fault tolerance.

More specifically, the slope angle of the guide slope 32 is between 20 ° and 30 °, and when the slope angle of the guide slope 32 is too small, the guide slope 32 does not play a role of guiding, and when the slope angle of the guide slope 32 is too large, the role of reducing damage when the machining platform 2 collides with the backing plate 3 is not played, so the slope angle of the guide slope 32 is between 20 ° and 30 °.

Referring to fig. 2 and 3, the workpiece 21 includes a plurality of stations 211, the plurality of stations 211 are processed sequentially, and when the first station 211 is processed, an edge of the processing platform 2 upstream in the feeding direction of the workpiece 21 is flush with an upper edge of the guide slope 32.

Specifically, when the milling cutter type plate separator performs cutting operation, the processed stations 211 are switched through feeding of the processing platform 2 and movement of the milling cutter 5, and the first station 211 is the station 211 which is closest to the downstream of the feeding direction of the processing platform 2 in all the stations 211. When the first station 211 is fed to the position right above the dust passage 31, the milling cutter 5 firstly processes the first station 211, and then switches the stations 211 according to a set route until all the stations 211 are processed. When the first station 211 is processed, one side edge of the processing platform 2 located at the upstream of the feeding direction of the workpiece 21 is flush with the upper edge of the guide inclined surface 32, so that the dust collector can still well suck the chips when the milling cutter 5 performs cutting operation on the station 211 after the first station 211.

Referring to fig. 5, the backing plate 3 has an ejection slope 33, the ejection slope 33 is located on a side of the backing plate 3 downstream in the feeding direction of the workpiece 21, and the ejection slope 33 is inclined downward in the feeding direction of the processing platform 2.

Specifically, the workpiece 21 is deformed after being machined, and these deformations may cause the air gap 12 between the workpiece 21 and the backing plate 3 to be too small, so that the workpiece 21 and the machining platform 2 are difficult to withdraw from above the backing plate 3, and the withdrawing slope 33 is inclined downward in the feeding direction of the machining platform 2.

More specifically, the slope angle of the exit slope 33 is between 20 ° and 30 °, when the slope angle of the exit slope 33 is too small, the length of the exit slope 33 becomes long, which occupies a large space, which is not favorable for reducing the volume of the milling cutter type plate separator, and when the slope angle of the exit slope 33 is too large, the workpiece 21 and the machining platform 2 are still difficult to exit from above the backing plate 3, so the slope angle of the guide slope 32 is between 20 ° and 30 °.
