Description
The present invention relates to a scrap inflow blocking device that prevents scrap from flowing into the T groove of the face plate in a large turning lathe and improves mobility of the chuck unit including a jaw, thereby improving worker convenience and work efficiency. will be.
In general, the problem of automation of production activities in machine shops with the advanced development of machinery industry is progressing to the task of achieving the purpose of improving productivity and quality while releasing man from mechanical work. Therefore, automation of machine tools has been developed from simple to complex, such as imitation cutting, automatic dimensional cutting, and the like, and has recently been developed and produced in NC machine tools with human brain capability using numerical control method. In this case, the NC machine tool includes an automatic lathe, an automatic sizing grinder, a transfer machine, and the like.
On the other hand, the automatic lathe is not only very inconvenient because the operator has to wipe the scrap and cutting oil attached to the chuck when holding the workpiece on the chuck, and then the workpiece is held on the chuck. there was.
In order to overcome this problem, although the Republic of Korea Patent Publication No. 2000-26110 and the Utility Model No. 1998-47449 and 1989-16236 have been invented, this also holds the workpiece to the chuck during the unmanned automatic operation of the automatic lathe In this case, it is difficult for an operator to remove the cutting oil and the scrap attached to the chuck. Therefore, holding the workpiece in the state that the scrap is attached to the chuck has a very bad effect on the degree of processing, there was a problem that causes the pore failure.
Accordingly, in the related art, an apparatus for removing scrap by spraying compressed air has been devised. Since the compressed air is unnecessarily sprayed after cutting is completed as well as during cutting, loss of compressed air is caused, and cutting oil is supplied during cutting, and the cutting oil is scattered by the compressed air, which is precisely applied to the cutting part. There was a problem that the supply efficiency is lowered because it is not supplied.
In addition, the scraps generated when cutting the workpiece to the hollow shaft through the automatic lathe or machining the workpiece with short diameter penetrates the hole formed in the center of the chuck, which makes it difficult to continuously work. After each operation is completed, compressed air After removing the scraps by spraying and setting the workpiece again, there was a hassle of working.
In order to solve this problem, Republic of Korea Patent Registration No. 10-1326247 (2013.10.31) "Scrap intrusion prevention device of the chuck provided in the automatic shelf" has been proposed.
The registered patent is configured to include a close contact with the outer surface of the chuck and the fixing member for fixing the blocking member and the sealing member was configured to prevent the inflow of scrap by sealing the entire face plate of the chuck.
However, the registered patent has a problem in that the manufacturing cost increases when applied to a large turning lathe because it is configured in a form surrounding the entire face plate.
Particularly, in the case of a large lathe, the jaw is configured to operate in a T groove formed on the face plate. In the case of the registered patent, there is a problem in that the effectiveness of the scrap is lowered because there is no configuration that can prevent the scrap flowing into the T groove.
The scrap inflow blocking device of the present invention for solving the above problems constitutes a guide block that can block the T-groove of the face plate, and coupled to the chuck unit by moving through the guide block to perform a scrap inflow prevention function and at the same time chuck unit An object of the present invention is to provide a scrap inlet blocking device that can move smoothly.
Still another object of the present invention is to adjust the degree of fastening of the second bolt that couples the first and second sliding parts and the chuck unit when the chuck unit moves so that the operator can easily move the chuck unit.
The present invention can block the T-groove formed in the conventional face plate so that there is no scrap flowing into the T-groove when machining the workpiece can improve the convenience and work efficiency of the operator.
In addition, since the jaw-containing chuck unit is moved in a state in which the coupling of the second bolt is loosened to improve mobility, the operator's convenience and work efficiency can be improved.
In addition, the first and second positioning pin coupling holes and the positioning pins coupled thereto enable the chuck unit to be disposed at a predetermined position, thereby improving workability. In particular, when the position display unit is formed, workability can be further improved. have.
In addition, it is a useful invention that can prevent the introduction of scrap into the guide block through the cap for preventing the introduction of scrap coupled to the first coupling hole of the guide block.

On the other hand, in the case of a chuck applied to a large turning lathe, the worker moves the jaw one by one and selects a position using a measuring means such as a tape measure.
That is, the conventional face plate is made of a structure in which the chuck unit is coupled to the T-groove, but the movement of the chuck unit has a problem that the productivity of the worker is lowered because the operator lifts it slightly after lifting the chuck unit.
