Description

Automatic takeout device for workpiece}

The present invention relates to a workpiece automatic take-out device that can automatically take out the workpiece is completed in the lathe chuck.

In general, the automatic workpiece take-out apparatus cuts the workpiece from the spindle with the cutting bit after processing the workpiece fixed to the spindle, and moves the cut workpiece to the predetermined position as described above.

Referring to the workpiece takeout process of the general workpiece takeout device is as follows.

First, a pneumatic cylinder fixing bracket is mounted on the upper part of the main shaft bar, and the shaft is fixed to the cylinder. The end of the pneumatic cylinder is assembled with a knuckle and fixed with a pin.

Then, the arm is bolted to the shaft fixed to the pneumatic cylinder, and the bucket is fixed to the end of the arm.

In addition, the lower cover is equipped with a cover for preventing the inflow of chips or cutting oil, the guide is adjusted to be fixed according to the size of the workpiece.

And the bracket is fixed to the bed and the workpiece box is mounted on the bracket.

In addition, a second bucket is disposed in the work box to receive a work falling into the work box.

Referring to the technique of the conventional work take-out device consisting of the above configuration is as follows.

First, when the processing of the workpiece fixed to the main shaft is finished, the pneumatic cylinder fixed to the upper portion of the main shaft to the linear movement, the position of the initial pneumatic cylinder piston rod is in the advanced state, the piston rod is advanced as described above The state in which the workpiece is taken out is in a state where the work is taken out.

Therefore, as described above, the piston rod of the pneumatic cylinder is reversed and the shaft is rotated immediately before the workpiece is finished and the workpiece is cut at the spindle, so that the arm is placed on the spindle.

Then, when the workpiece is cut and falls on the bucket disposed below the main shaft, the piston rod of the pneumatic cylinder is advanced.

Therefore, as the piston rod moves forward, the shaft is rotated, and the arm and the bucket coupled to the arm are rotated downward with the shaft as the center point.

At this time, the pin fixed to one side of the bucket is in contact with the guide, the bucket is rotated by the guide is to drop the workpiece inside the second bucket of the workpiece box.

In addition, the guide must be adjusted in position so that the bucket is rotated to fall inside the workpiece and must match the pin position fixed to the bucket for smooth operation.

However, the general workpiece taking out device has a problem that the surface of the workpiece is damaged as the workpiece falls into the bucket 03.

Further, Korean Patent Application Laid-Open No. 1998-0006945 discloses a blowout plate having a hole smaller than the outer diameter of a workpiece coupled to a chuck of a lathe between a turning workpiece and a lathe chuck, so that the blowout plate is transferred left and right. Although the structure of the workpiece taking-off device of a lathe is disclosed, the cutting chip and the cutting oil are discharged to the extraction plate when the workpiece is processed, and it is necessary to wash the extraction plate, and the workpiece is damaged by hitting the chute.

In addition, the prior art document No. 0393854 for the Korean Registered Room is a first vertical frame installed in the CNC lathe to be exposed to the outside in a vertically standing state in the CNC lathe, and the first vertical A second vertical frame positioned on the same line as the frame and installed vertically outside the CNC lathe, a horizontal frame lying horizontally on the first and second vertical frames, and installed on the horizontal frame It is coupled to the movable platform horizontally moved forward and backward by the power of the motor, and the rod of the elevating cylinder installed on the movable platform, and is moved horizontally before and after the operation of the movable platform to move the workpiece above the CNC lathe. It consists of a plurality of clamps that move up and down vertically by the operation of the cylinder and feed and withdraw the workpiece to the chuck in the CNC lathe. Although the workpiece supply and withdrawal device of a CNC lathe has been disclosed, the take-out time of the workpiece is delayed due to the clamping of the workpiece and the opening / closing process of the door in the process of taking out the workpiece, and frequent troubles are caused by repeated opening and closing of the door. There was a problem in that the cost of repair and maintenance of the door frequently occurs.
