This will be described in more detail as follows.

2 shows a material detachment apparatus of the present invention, wherein the body 3 includes a base 31 having a first actuator 311 mounted at the rear thereof and a stopper 312 mounted at the front thereof, and the base 31 mounted thereon. Is installed on the upper side and the rear side is connected to the rod 311a of the first actuator 311, the hinge is provided on the upper side and the one side to rotate the housing 32 at a predetermined angle and the second The intermediate bracket 32 is provided with a left and right rotating means 321 made of an actuator 321a, and the arm mounting portion 331 is provided on the upper side of the middle bracket 32, the front of which is open at the bottom, It consists of a housing 33 having a pinion 332 is installed so that it can be rotated in accordance with the forward and backward movement of the rake (321b) constituting the left and right rotation means (321).

The arm 4 is fixed to the arm mounting portion 331 formed on the upper side of the housing 33 through a hinge shaft 41, and has a pinion 421, a leg 422, and a third behind. It includes a front and rear rotation means 42 made of an actuator 423. In particular, the front and rear rotation means 42 is a pinion 421 fixed to one end of the hinge shaft 41 for fixing the arm 4, and is located on the lower side of the pinion 421 is sliding in the housing 33 And a third actuator 423 fixed to the rear of the housing 33 so as to advance and move the rack 422.

In addition, the material receiving unit 5 is installed on the upper side of the arm (4) can be reversed and reversed through the forward and reverse motor 53, the housing 51 and the front receiving port 52 on both sides of the rotation shaft (531) It is characterized by consisting of a material receiving unit (5) consisting of.

In particular, the material detachment device is installed in the casing (6) forming the CNC lathe to discharge the material bitten by the main shaft (1) to the outside, and supplies the external material back to the main shaft (1).

On the other hand, the front of the casing 6 of the CNC lathe is provided with a conveyor (7) for moving the material on the upper side.

Hereinafter will be described the operation relationship of the present invention.

As shown in Fig. 1 and Fig. 2, in the case of receiving the finished material held by the spindle 1 provided on both sides of the CNC lathe and discharging it onto the conveyor 7,

First, the second actuator 321a of the left and right rotating means 321 installed on one side of the intermediate bracket 32 constituting the body 3 is advanced to the material receiving part 5 installed on the upper side of the arm 4 on one side. It moves forward of the located main shaft 1. Then, when the rod 311a of the first actuator 311 installed in the base 31 is retracted, the housing 33 and the arm 4 are retracted, and the rear of the material receiving unit 5 installed on the upper side of the arm 4. The front receiving port 52 located in the grab the processed material is bitten by the main shaft (1).

Next, the rod 311a of the first actuator 311 is advanced to separate the processed material from the main shaft 1, and then the stationary motor 53 constituting the material receiving part 5 is operated to operate the material. Replace the unprocessed material located at the front. That is, the material receiving unit 5 is rotated 180 degrees about the rotation shaft 531 through the stationary motor 53.

Next, when the rod 311a of the first actuator 311 is retracted again, the front receiving port 52 of the material receiving unit 5 installed on the upper side of the arm 4 pushes the material to the main shaft 1. The raw material is fixed to the main shaft (1). On the contrary, when the rod of the first actuator 311 is advanced, the housing 33, the arm 4, and the material receiving part 5 are retracted again.

Thereafter, the first actuator 311 of the left and right rotating means 321 installed on one side of the intermediate bracket 32 of the body 5 is retracted to an intermediate position so that the material receiving part 5 installed on the upper end of the arm 4 It is to return to the intermediate position of (1), ie, the original position.

In addition, when discharging the processed material separated through the above operation onto the front conveyor, first, the rod 422 is retracted by retracting the rod of the third actuator 423 mounted on one side of the housing 33. By reversing and causing the pinion 421 located at one end of the hinge shaft 41 to rotate in the reverse direction, the arm 4 is rotated forward 90 degrees about the lower hinge shaft 41. Therefore, the processed material which was located at the rear of the material receiving unit 5 is put on the conveyor and discharged to the outside.

On the contrary, when receiving the raw material moved on the conveyor, that is, when the rod of the third actuator 423 advances to a small distance in the next order of the discharge process and then retracts the rod and returns the conveyor ( 7) The front receiving port 52 is to hold the unprocessed material that has been moved up.

Then, when the rod of the third actuator 423 is advanced, the arm 4 is rotated 90 degrees as the lever 422 is advanced and the pinion 421 located at one end of the hinge shaft 41 is rotated in the forward direction. It is rotated and returned to the initial position.

On the other hand, the processed material of the main shaft (1) located on the other side is to replace the discharge through the same operation.

The present invention as described above, by mounting the material detachment apparatus inside the CNC lathe can reduce the volume of the CNC lathe as a whole, enabling the swing operation when the material detachment of the spindle to shorten the non-processing time according to the material detachment There is an effect that can increase the productivity for.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. Therefore, the true technical protection scope of the present invention should be defined only by the appended claims.
