Description

Sliding cover of machine tool

The present invention relates to a sliding cover of a machine tool, and in more detail, the moving body moves linearly along the linear motion guide of the conveying body by the rotational movement of the ball screw. The slide welded in the innermost cover is assembled or stopped by the stopper assembled at the end of the rod when assembling the round bar with the stopper at the end of the linear motion guide. It relates to a slide cover of a machine tool.

A general machine tool has an information processing circuit which inputs numerical information programmed according to the design drawing to manufacture a workpiece, and the cutting process is performed by operating a servo mechanism that controls the power of the machine tool in a given command circuit. .

Here, the servo mechanism is a drive unit which feedback-controls the commanded mechanical position, speed and the like while maintaining a predetermined precision. The workpiece is cut by operating the table while matching the characteristics of the mechanical system and the servo system.

These servomechanisms usually use DC motors for speed and torque, and the control of such machine tools requires the provision of unique torque speed characteristics. That is, it has a large torque for heavy cutting in the low speed area, and the speed required for fast feed should be obtained in the high speed area, and a large rated torque is not necessary, but to obtain excellent acceleration and deceleration characteristics, it is instantaneously large over the entire speed area. Torque must be available.

Such a conventional machine tool is a moving body linear motion guide for converting the power transmitted to transfer the workpiece by using a servo mechanism to rotational power as shown in FIG. ), And the fixed part (2) is connected to the inner center so that the movable body linear movement guide (1) is fixed and unfolded and reduced, and the number of externally to prevent the intrusion of chips or other contaminants. The sliding cover 3, which is overlapped, and the conveying body linear motion guide 4 connected to the moving body linear motion guide 1 so that the workpiece can be processed while advancing back and forth are connected.

In the conventional machine tool configured as described above, the conveying member 4 moves according to the rotational direction of the ball screw so that the workpiece can be processed, and the fixing part 2 is provided at the end of the conveying member linear motion guide 1. The sliding cover 3, which is fixed to each other and is surrounded by a plurality of bodies on the outside, is unfolded so that the sliding cover 3 can be returned to its original position and prevents chips or other foreign substances falling from the workpiece through the sliding cover 3 from being contaminated. Will be done.

However, such a conventional machine tool is fixed to the conveying body linear motion guide is connected to the front end of the body of the sliding cover is difficult to secure more space when the sliding cover is expanded or reduced, so that other parts to the limited size machine tool There was no space left to install or connect.

The object of the present invention is to solve such problems in the related art. The object of the present invention is to move the linear motion along the linear motion guide of the moving object by the rotational movement of the ball screw. Assemble a round bar with a stopper at the end of the conveying body linear motion guide so that it can occur more and the slide welded in the innermost cover when the sliding cover expands or contracts along the round bar is fixed by a stopper assembled at the end of the bar To stop the collapse.

DETAILED DESCRIPTION Hereinafter, the most preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily implement the present invention. . Other objects, features, and operational advantages, including the purpose, operation, and effect of this design, will become more apparent from the description of the preferred embodiment.

For reference, the embodiments disclosed herein are only presented by selecting the most preferred examples to help those skilled in the art from the various possible examples, and the technical spirit of the present invention is not necessarily limited or limited only by this embodiment. In addition, various changes and modifications are possible within the scope without departing from the technical spirit of the present invention, as well as other embodiments of the equally clear.

Figure 2 is a configuration diagram of a machine tool sliding cover according to an embodiment of the present invention, Figure 3 is a configuration diagram of the expanded state of the machine tool sliding cover of FIG.

The present invention relates to a sliding cover of a machine tool, as shown in FIG. 2 or 3, the transfer body for converting the power transmitted from the outside to the rotational power to move the workpiece to move forward and backward combined machinery The linear motion guide 10 and the outside of the conveying body linear motion guide 10 are surrounded by a plurality of layers so as to prevent the intrusion of chips or other contaminants, and the moving direction of the linear motion guide. Sliding cover 20 and interlocked so as to expand and shrink according to the configuration, and the conveying body 40 is connected to the conveying body linear movement guide 10 is moved forward and backward to allow the workpiece to be processed Has

The conveying body linear movement guide 10 is limited to a predetermined length, and the sputter 11 is connected to a predetermined portion so as to stop the expansion and the movement of the sliding cover 20 by the stopper 11. It has a configuration that the cylindrical round bar 30 is fixed to one side of the innermost cover 21 of the sliding cover 20 is connected to be limited.

If described in detail the effect of the present invention is configured as follows.

The present invention relates to a sliding cover of a machine tool, and as shown in FIG. 2 or 3, when the conveying body linear motion guide 10 is operated by external power, the conveying body linear motion guide 10 Connected conveying body 40 transfers the workpiece so that the work can be done, and to prevent chips and other foreign substances generated while processing the workpiece from the conveying body 40 to fall into the machine tool to cause contamination The sliding cover 20 is to be assembled to the conveying body linear motion guide (10).

The sliding cover 20 covers the entire body and the ball screw of the conveying body linear motion guide 10 when the displacement of the conveying body 40 is expanded, and in conjunction with that the displacement of the conveying body 40 is reduced. Multiple cover bodies can be stacked on the outside so that they can be reduced.

Here, the sliding cover 20 covers the conveying body linear movement guide sphere 10 and at the same time, the conveying body on the other side of the innermost cover 21 located on the innermost side so that expansion can be restricted at a certain distance during expansion. The linear motion guide 10 can be assembled and the cylindrical round bar 30 is connected to one side of the innermost cover 21.

In addition, the sliding cover 20 is fixed to the stopper 11 in a fixed position so that expansion can be stopped by the stopper 11, the innermost cover 21 and the external machine tool of the sliding cover 20 during expansion The gap between them is to be enlarged.

The present invention acting as described above causes the moving body to move linearly along the conveying body linear motion guide by the rotational movement of the ball screw. The slide welded in the innermost cover when the round bar having the stopper at the end is assembled and the sliding cover is expanded or contracted along the round bar has the effect that it can be stopped or stopped by the stopper assembled at the round bar end.
