Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a chip removal device for a super-finishing planer, which is equipped with means for forcibly removing chips accumulated at the cutting edge.

Conventionally, in super-finishing planing machines in which the material feeding member is placed below the material feeding path and the elevating member that supports the tool rest is placed above, chips accumulate on the cutting edge and the turret and cause damage to the finished surface of the material. There were some inconveniences, such as damaging the blade and not being able to smoothly remove the chips, so when replacing the blade, the blade could not be set unless the chips were thoroughly removed.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a chip removing device for a super finishing planer which eliminates the above-mentioned drawbacks and can smoothly discharge chips.

The chip removal device for a super-finishing planer of the present invention includes a material feeding member driven by a material feeding electric motor to feed material, and a planing blade that is rotatably attached to an elevating member that is opposite to the upper surface of this material feeding member. A tool rest provided with a tool rest fixed to the tool rest, and a means for adjusting an interval of a material feeding path formed between the tool rest, the lifting member side and the material feeding member, through which the material is fed, and disposed on the lifting member. The installed blower and the nozzle, which is installed on the tool rest and has openings facing each other at the cutting edge, are communicated through a bendable blower pipe.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the chip removing device for a super finishing planer according to the present invention will be described below with reference to FIGS. 1 and 2. FIG. 1 shows a side view and FIG. 2 shows a plan view. Reference numeral 1 denotes a support member to which a frame 2 is fixed, and the frame 2 is provided with an endless belt 5 as a material feeding member and a material feeding electric motor 4 for driving the endless belt 5.
17 is a switch for the electric motor 4 for material feeding.

On the upper surface of the endless belt 2, a tool rest 9 is rotatably supported on the turn piece 10 of the elevating member 3 and has a front blade 11 of a planer blade attached thereto.
They are arranged opposite to each other across the material feeding path. The front blade 1 of the tool rest 9 is fixed via the back blade 12, and a blade mouthpiece 13 is disposed opposite to the front blade 11, and a blade mouth portion 19 is provided between the front blade 11 and the blade mouthpiece 13. It is formed. Further, the elevating member 3 is supported by the frame 2 via a plurality of columns 6 so as to be able to rise and fall, and is configured to be raised and lowered by rotating a screw shaft 8 through an elevating handle 7. The height of the material feeding path between the member 3 and the endless belt 5 of the material feeding member is adjustable.

Further, a blower 14 is disposed on the upper surface of the elevating member 3, and a nozzle 15 is attached on the tool rest 9, the opening of which is disposed opposite to the blade mouth portion 19.
The blower 14 and the nozzle 15 are communicated through a bendable blower pipe 16. The blower 14 is driven by simultaneously opening and closing the motor circuit using a switch 17 for driving the material feeding motor 4. Even when the tool rest 9 is rotated to give the planer blade an oblique angle depending on the type of material 18, sufficient air can be blown to the blade opening 19.

When processing the material 18 using this super finishing planer, after adjusting the height of the material feeding path to suit the material 18 using the lift handle 7, operate the switch 17 to pass the endless belt through the material feeding motor 4. At the same time, the blower 14 is driven to start blowing air to the blade opening 19 as shown by the arrow. Next, when the material 18 is fed into the material feeding path, cutting is performed by the front blade 11. Since the chips are blown away by the wind blown from the tip of the nozzle 15 from the blower 14 through the blow pipe 16, they are prevented from accumulating in the blade opening 19. Therefore, it is no longer possible to damage the finished surface due to chips remaining in the blade mouth part 19 as in the past, and operability is improved because there is no need to remove accumulated chips when replacing the blade. can.

As described above, the chip removal device for a superfinishing planer according to the present invention has the effect of smoothly discharging chips and improving operability.
