Scrap preventing apparatus

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.

The guide block 10 is an intermediate plate which is integrally formed on the lower plate 11 and the lower plate 11 formed with the first coupling hole 11a to fasten the first bolt B1. 12 and the upper plate 13 formed integrally with the intermediate plate 12, the width of the intermediate plate 12 is formed in a smaller size than the lower plate 11 and the upper plate 13 It is good to configure so that the guide groove 14 can be formed.

Here, although not particularly limited, the upper plate 13 may be formed to have a smaller width than the middle plate 12, but smaller than the lower plate 11.

Next, the first sliding portion 20 forms a protrusion 21 extending downward to abut on the upper side and the side surface of the upper plate 13 constituting the guide block 10, the overall shape is c The second coupling hole is formed in an upright shape and penetrates from the upper side to the bottom surface of the protruding portion at an upper side of the sliding portion 20, more specifically, at a position where the protruding portion 21 is formed. (22) is formed.

Next, the second sliding part 30 is coupled to the lower side of the protruding portion 21 of the first sliding part 20, but collinear with the second coupling hole 22 formed in the first sliding part 20. The fastening hole 31 which formed the screw thread located in this structure is comprised.

Next, the chuck unit 40 is configured to be coupled to the upper side of the second sliding 30 through the second bolt (B2).

The second bolt B2 may connect the coupling hole 31 of the second coupling hole 22 and the second sliding part 30 formed in the chuck unit 40 and the first sliding part 20. It is composed.

In addition, a jaw (J) is configured at an upper portion of the chuck unit 40, and the jaw (J) is coupled to the chuck unit body 41 of the chuck unit 40 and slides through the jaw moving means 42. It is configured to be made.

On the other hand, in the present invention is coupled to the first coupling hole (11a) formed in the lower plate 11 of the guide block 10 to fill the upper side formed with the first coupling hole (11a) of the lower plate (11). Scrap inflow prevention cap (C) may be further included.

The scrap inflow prevention cap (C) may be formed of various materials, but it is preferable to form a synthetic resin series made of a material that is easy to remove and attach and prevent the scrap from being introduced into the first coupling hole 11a.

On the other hand, in the present invention it can be further added to the configuration that can be moved at a predetermined interval when the first, second sliding portion 20, 30 and the chuck unit 40 moves.

That is, the first positioning pin coupling hole 13a through which the positioning pins P can be fixed at regular intervals is formed at both ends of the upper plate 13 formed in the guide block 10, and corresponding to this. In the first sliding part 20 of the position, a second positioning pin coupling hole 23 capable of engaging the positioning pin P is formed to form the first and second sliding parts 20 and 30 and the chuck at regular intervals. It is possible to move the unit 40.

Looking at the effect of the scrap inflow blocking device 100 of the present invention made of a configuration as described above are as follows.

First, the scrap inflow blocking device 100 of the present invention is in the form of a rail to move the chuck unit 40, while preventing the scrap from flowing into the T groove (T) formed in the existing face plate (F). The guide block 10 is configured to act to shorten the working time according to the scrap removal to improve the work efficiency.

Of course, even when the guide block 10 and the first and second sliding parts 20 and 30 are configured as described above, the first sliding couples to the guide groove 14 and the guide groove 14 of the guide block 10. Scrap may flow into the U-shaped portion formed by the side of the protrusion 21 formed on the part 20 and the upper side of the second sliding part 30.

However, in the case of the above-mentioned parts, since the scrap can be easily removed through a scrap removing means such as an air gun, it is possible to shorten the working time by reducing the time required to remove the scrap compared to the conventional method.

Meanwhile, in the present invention, the scrap is guided to the guide block 10 through a cap inflow prevention cap C which can fill the upper portion of the first coupling hole 11a formed in the lower plate 11 of the guide block 10. Inflow can be prevented.

That is, the guide block 10 may be coupled to the first bolt (B1) that can be coupled to the T nut (N) coupled to the T groove (T) of the face plate (F) from the upper side of the lower plate (11). It consists of structures that can be.

At this time, since the first coupling hole 11a of the lower plate 11 is formed above the lower plate 11, scrap may flow into the first coupling hole 11a.

In the present invention, the above-mentioned scrap inflow prevention cap (C) is coupled to the first coupling hole (11a) to the filling process is to act to achieve the above object.

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.

However, in the present invention, the first and second sliding parts 20 and 30 sliding through the guide block 10 and the chuck unit 40 coupled thereto are moved at regular intervals according to the size of the workpiece to facilitate position adjustment. Can be done.

If you describe this process,

Initially, the first and second sliding parts 20 and 30 are completely tightened because the fastening of the second bolt B that couples the chuck unit 40 and the first and second sliding parts 20 and 30 is tight. The bond is kept tight.

The protrusion 21 and the second sliding part 30 of the first sliding part 20 thus coupled are guide grooves 14 formed between the upper plate 13 and the intermediate plate 12 of the guide block 10. The first and second sliding parts 20 and 30 are in close contact with each other to maintain a fixed state in a non-movable state.

Then, when the size of the workpiece is different and the necessity to move the chuck unit 40 occurs, the second bolt (B) that is fixedly coupled to the chuck unit 40 and the first and second sliding parts (20, 30) When the coupling is released to the extent that the coupling is loosened, the coupling between the first and second sliding parts 20 and 30 is loosened to form a state in which each of the coupling parts is spaced apart from each other so as to be movable in the guide block 10.

Then, the operator can easily move the chuck unit 40 without a large force.

On the other hand, in the present invention it is possible to move the chuck unit 40 at equal intervals during the movement of the chuck unit 40 can further improve the convenience of the operator.

Typically, the chuck unit 40 for clamping the workpiece is used to move the chuck unit 40 itself according to the size of the workpiece, and then use the jaw moving means 42 formed in the chuck unit 40 to finely adjust the position. Done.

When the chuck unit 40 itself is moved as described above, in the present invention, the chuck units 400 are equally spaced apart using the positioning pins P and the first and second positioning pin coupling holes 13a and 23. You can move it.

That is, as described above, two second positioning pin coupling holes 23 are formed in the first sliding part 20 to couple the positioning pin P, and the guide block 10 is formed in the first sliding part 20. Both side surfaces of the upper plate 13 form a first positioning pin coupling hole 13a to which the chuck unit 40 can be fixed when the positioning pin P is coupled.

Accordingly, the operator inserts the positioning pin P into the second positioning pin coupling hole 23 while the operator arranges the first and second sliding parts 20 and 30 and the chuck unit 40 at an arbitrary position. Afterwards, the first and second sliding parts 20 and 30 and the chuck unit 40 are gradually slid to reach a section in which the first positioning pin coupling hole 13a formed in the upper plate 13 of the guide block 10 is located. When the positioning pin (P) is coupled to the first positioning pin coupling hole 23 it is possible to move the first and second sliding parts (20, 30) and the chuck unit 40 in the correct position.

Here, when the position display portion 13b is further formed on the upper plate 13 formed on the guide block 10, a plurality of first and second sliding parts 20 and 30 coupled to the face plate F and It is possible to visually check the work and the movement amount to place the chuck unit 40 in the same position can further improve the convenience of the operator.

On the other hand, the first and second sliding parts 20 and 30 and the chuck units 40 that have been moved as described above are completely positioned by the operator when the second bolt B2 formed in the chuck unit 40 is completely fastened. It can be moved and fixed to.

Then, using the jaw moving means 42 formed in the chuck unit 40, the jaws J are placed in a position where the workpiece can be clamped, so that the operator can move each jaw J or the chuck unit 40 one by one. Even if you do not measure the position of the can be placed in the correct position.

As described above, the present invention prevents the flow of scrap into the T-groove T formed in the existing face plate F, thereby improving convenience and work efficiency of the worker, as well as moving the chuck unit 40. The convenience of work and the placement of the work in the correct position can be easily performed to improve the efficiency of the worker.

Although the above-described embodiments have been described with respect to one preferred embodiment of the present invention, the present invention is not limited thereto and may be modified and implemented in various forms within the scope not departing from the spirit of the present invention. It should be obvious to those skilled in the art.
