PURPOSE: A length adjusting apparatus using a sleeve in a CNC(Computer Numerical Control) lathe is provided to prevent shaking caused by eccentricity during the processing of small size products. CONSTITUTION: A length adjusting apparatus using a sleeve in a CNC lathe comprises a length adjustable bar(20) and a fixing nut(30). The length adjustable bar is detachably installed on the rear side of a workpiece insertion hole(10). The length adjustable bar is divided into a rod(200) and a screw(210). The screw thread is not formed on the outer circumference of the rod. The screw has a screw thread(211). A handle(201) is integrated with the other side of the length adjustable bar. The fixing nut is formed in the screw.

Description

Equipment to control length of artifact to use sleeve in CNC lathe}

The present invention relates to a workpiece length adjusting device using a sleeve,

Specifically, by adjusting the length of the workpiece to be processed, the workpieces that require various lengths are moved to a suitable CNC lathe for each required length, and the various lengths of one CNC lathe are not processed. The present invention relates to a workpiece length adjusting device using a sleeve in OneCNC lathes for processing a workpiece.

As is well known, CNC (Computerized Numerical Control) Lathes program data of machining shape, processing conditions and machining operation by computer, and keep it in pulse signal state by numbering control data and supplying it based on this. The machine tool that processes the machine.

Conventional CNC lathes are equipped with sleeves to prevent workpieces from flowing on the front and rear sides of long installed rails, but the sleeves on the side are fixed without movement, and the rear sleeves are fitted with a combination of motor, chain gear and chain. ㆍ Installed to move backwards, the chuck is fixedly coupled to the outer circumference of the sleeve, and inserts the workpiece into the center workpiece insertion hole of the sleeve without movement, and then the moving sleeve moves forward by the operation of the motor and cylinder and rotates at high speed. It is to be able to process the workpiece, that is, the bite work or turning work.

In the workpiece insertion hole of the sleeve that does not move in the conventional CNC lathe as described above, there is a problem that the workpiece is inserted and fixed, but the length to be processed cannot be freely adjusted.

In other words, for example, a CNC lathe that processes small workpieces of 4 and 6 inches in length must be moved to a separate CNC lathe to process secondary workpieces in order to process 8 and 10 inch lengths of workpieces.

Specifically, existing CNC lathes are small and medium sized companies that do not have a complete machine, and are mostly divided into 4 or 6 inch holders and 8 or 10 inch holders.

In the case of outsourcing products processed by 8 (inch) or 10 inch CNC lathes, they do not receive orders for small quantities when they are outsourced, and the processing price increases, and the delivery price increases due to logistics costs between the 1st and 2nd companies. Due to the possibility of weakening of the competitiveness, and the work is not finished in one process, it is necessary to check the precision tolerance, which is a problem of quality control, and the defects caused by the inability to check the dimensional change caused by the amount of wear of the bite. There is a problem of increased risk, and when machining a short workpiece, the depth of the workpiece caught in the sleeve is short, which causes the workpiece to splash on the worker or other people when the product is displaced during the turning process of the CNC lathe. It is exposed to and also causes unevenness and eccentricity. There is a difficult problem.

The present invention for solving the above problems,

It is an object of the present invention to provide a sleeve that is capable of freely machining workpieces of various lengths with a single CNC lathe, thereby making it easy to control quality due to uniformization, reducing risk by reducing defect rate, and saving time and economy. will be.

Specific solution means for achieving the above object,

"In the usual having a sleeve having a workpiece insertion hole having a variety of diameters in the center, it is provided to be removable on the back of the workpiece insertion hole for adjusting the length partitioned by a screw having a thread and a rod without a thread on the outer peripheral surface on one side The other side of the bar for adjusting the length of the bar is integrally formed with a handle and the screw is provided with a fixing nut,

The workpiece insertion hole is tapered from the inner center to the rear side thereof, thereby achieving the above object.

The present invention as described above has the economic and time-efficiency of reducing the two processes to one by enabling the processing of the various lengths in a single CNC lathe workpieces that require a variety of lengths,

It is easy to produce small products that are difficult to produce by companies with 8- or 10-inch equipment, and products from 3Ø to 14Ø can be easily produced. It is easy to control quality, and it can prevent shaking and deviation caused by eccentricity when processing small products.

In addition, the product quality is thoroughly managed to satisfy the buyer's needs, and the risk of defects can be greatly reduced by reducing the defective rate due to the stable production of the product, and the appearance defect can be prevented by preventing the shaking of the product. The company can also win orders, strengthening its competitiveness.

In the above, the present invention has been illustrated and described with reference to specific preferred embodiments, but the present invention is not limited to the above-described embodiments, and the present invention may be applied to those skilled in the art without departing from the spirit of the present invention. Of course, various changes and modifications are possible.

Hereinafter, the specific configuration and operation of the workpiece length adjustment device using the sleeve in the present inventors CNC shelf will be described with the drawings.

Figure 1 is a perspective view of the workpiece length adjustment device using a sleeve in the inventors of CC One shelf, Figure 2 is an exploded perspective view of the workpiece length adjustment device using a sleeve in the inventors oneCNC shelf, Figure 3 is It is sectional drawing of the workpiece length control apparatus using a sleeve, and FIG. 4 is a schematic diagram of a oneCNC shelf in the workpiece length adjustment apparatus using a sleeve in the oneCNC shelf of this invention.

Specific configuration of the present invention,

Known technology in the present invention is a one-CNC lathe having a sleeve (1) having a workpiece insertion hole 10 having a variety of diameters in the center is known.

In the known configuration as above,

The technical contents of the present invention are provided to be detachable to the rear of the sleeve 1, that is, to the rear surface of the workpiece insertion hole 10, and one side of the front is provided with a threadless rod 200 and a thread 211 on the outer circumferential surface thereof. Length adjustment bar 20 partitioned by screws 210,

The other side of the length adjustment bar 20 is formed with a handle 201 integrally and the screw 210 is provided with a fixing nut 30 is configured as that configuration,

Preferably,

The workpiece insertion hole 10 is tapered from the inner center to the rear thereof.

In the following description,

First, insert the workpiece to be processed into the workpiece insertion hole 10, and then rotate the handle 201 to move the length of the length adjusting bar 20 forward and backward, and then fix it with a fixing nut 30. After inserting the workpiece to the front of the workpiece insertion hole 10 and then fixing the sleeve (1) using a chuck,

By moving the processing tool is to rotate the workpiece fixed to the workpiece insertion hole 10 to be processed exactly as long as the length of the portion to be processed by the processing tool.

In other words, by using the handle 201 by the length adjusting bar 20 to allow the workpiece to be pushed back further or to project only the correct processing site to enable the working surface of various lengths in the present invention.

In addition, the diameter of the workpiece insertion hole 10 can be supplied to the manufacturer by setting a variety of sleeves up to 3Ø ~ 14Ø into one, so that the small micro-manufacturer operating the existing oneCNC shelf of various lengths and various diameters It is to be able to produce the workpiece.
