Description

Tool setter protector of a machine tool

The present invention relates to a tool setter protection device of a machine tool, and more particularly, to prevent penetration of various foreign substances generated during cutting into a tool setter installed for precise tool setting in a machine tool, especially a vertical machining center. A tool setter protection device for machine tools.

In general, a tool must be used for machining a workpiece in a numerically controlled machine tool. However, since there is a difference in shape for each tool, a program is produced with basic coordinate values without considering the shape of the tool. For this reason, when machining the actual workpiece, the actual machining can be achieved only by inputting data of the shape (length), wear data, etc. of the tool according to the tool used. These data are called Tool Offsets.

In order to input these data, the actual measurement is performed manually for each tool, and after setting the program reference coordinate and the tool, the difference between the coordinate values is calculated and inputted. Tricky comes with In order to eliminate such inconvenience, a tool setter using a position detecting device called a probe has recently been applied.

The tool setters are slightly different depending on the lathe and machining center, but they are all located on the machining area of the workpiece.

In particular, in the case of a vertical machining center, as shown in FIG. 1, a tool setter is located at the rear of the pallet table 20, which may correspond to the vertical position of the spindle head 40 in which the horizontal and vertical movements are free. 30) have been installed.

However, since the conventional tool setter 30 is an open type exposed to the outside air, cutting oil and cutting chips generated during processing act as a factor to hinder the tool setting operation. Also, a strong air pressure injection force is used during the tool setting operation. There was a hassle to clean the tool setter.

The present invention has been devised to solve the above problems, and its purpose is to protect the tool setter of a machine tool which protects the foreign materials generated during cutting into the tool setter installed for precise tool setting. In providing a device.

In order to achieve the above object, the present invention is a tool setter protector for a machine tool installed at the rear end of a pallet table,

A box-shaped protector which is built in to protect the tool setter and has an opening having a circumferential curve thereon;

An opening / closing door formed of a curve having the same circumference as the opening portion, the opening and closing period being integrally formed from one side to a center point of the circumference curve, and selectively closing / opening the tool setter;

A rotary link axially coupled to rotate the opening and closing of the opening and closing door;

A tool setter protection device comprising a; opening / closing operation lever coupled to each end of each of the rotary links and opening and closing the door while interacting with each other;

The eccentric side of the spindle head has a feature configured to include a push block for selectively opening and closing the open / close door by selectively pressing the open / close operating lever during operation for tool setting.

Figure 2 is a front view showing the appearance of the machine tool is configured with a tool setter protection device of the machine tool according to the present invention, Figure 3 is an enlarged cross-sectional view of the main portion as seen in 'A' of Figure 2, (a) (b) ) Is an operation view seen from the right side of FIG.

The structure of this invention is the tool setter protection device 10 of a machine tool installed in the rear part of the pallet table 20,

A box-shaped protector 12 is formed to protect the tool setter 30 and is formed with an opening 11 having a circumferential curve thereon. The protector 12 is a steel material in which the sides and the bottom are sealed while the upper part is opened, and the lower part is fixed to be installed at the rear of the pallet table 20 which is not included in the work area of the workpiece. (12a).

In addition, the top of the protector 12 is formed in a curve having the same circumference as the opening 11, the opening and closing period 13 is formed integrally from one side to the center point of the circumference curve, the tool setter 30 Form an opening and closing door 14 to selectively seal / open within a certain range (90 °).

Meanwhile, a door support 15 is fixedly installed at one side of the protector 12 to support the open / close door 14 including the opening and closing period 13, and the door support 15 is provided with the following components. do.

The rotary link 17 is fixed to the apex of the circumferential curve of the opening / closing door 14 by the shaft pin 16 so as to rotate the opening / closing body 13 integrated with the opening / closing door 14. . Longitudinal holes 17a are formed at both ends of the rotary link 17, and the opening and closing doors 14 are opened and closed by a 90 ° rotational movement in the form of a seesaw.

In addition, the opening and closing operation of opening and closing the door 14 by moving the rotary link 17 in the form of a seesaw while being coupled to each other in the vertical direction so as to be swingable to the long hole (17a) at both ends of the rotary link (17). The levers 18-1 and 18-2 are coupled to the door support 15 so as to vertically move.

On the other hand, on the eccentric side of the spindle head 40 is provided with a push block 19 for selectively opening and closing the opening and closing door 14 by selectively pressing the opening and closing operation lever (18-1) (18-2) during the operation for the tool setting. It is provided.

Referring to the operation of the present invention configured as described above are as follows.

Before machining the workpiece, the spindle head 40 is first moved toward the tool setter protector 10 in which the tool setter 30 is embedded in a predetermined order for tool offset. The opening / closing door 14 of the tool setter protection device 10 at this time is in a closed state as shown in FIG.

When the push block 19 of the spindle head 40 reaches the vertical position of the one-side open / close control lever 18-1, the spindle head 40 moves downward to press the open / close control lever 18-1 downward. do.

One side opening and closing operation lever 18-1 is pressurized to rotate the rotary link 17 coupled to the long hole (17a) to a certain range (90 °), at this time the other opening and closing operation lever (18-2) to the relative movement Protrude upwards.

At the same time, the opening and closing section 13 fixedly coupled by the rotary link 17 and the shaft pin 16 has an opening and closing door 14 integrally formed by the rotation of the rotary link 17. (11) Make the trajectory move away from it.

Thereafter, while the spindle head 40 operates, a specific tool mounted on the spindle head 40 contacts the tool setter 30 exposed through the opening 11 of the protector 12 to perform a tool offset operation.

When the tool offset operation is completed, the push block 19 of the spindle head 40 presses the opposite opening and closing operation lever 18-2 by a predetermined flow as shown in (b) of FIG. The opening and closing door 14 is operated in a reverse direction by the downward movement of the operation lever 18-2, so that the opening and closing door 14 isolates and protects the tool setter 30 in the protector 12. .

The above operations are written in one program to be operated at regular intervals in consideration of the machining time or the number of machining of the workpiece, so that the wear of the tool is compensated on the data so that the degree of wear of the tool does not affect the degree of the workpiece.

The present invention described above is not limited to the above-described embodiments and drawings, and various substitutions, modifications, and changes can be made without departing from the technical spirit of the present invention. It will be apparent to those who have

When the tool setter protection device of the present invention is applied as described above, the tool setter is always isolated from the foreign matter such as cutting oil or cutting chip during the machining operation, and the tool setter is selectively opened and closed for the tool offset. Not only the disturbing factor is removed but also the closed type, the conventional hassle to clean the tool setter by using the blowing force of pneumatic pressure is removed, thereby contributing to the convenience of the operator.
