Description

X-axle sliding cover structure of Y-axle CNC lathe}

The present invention relates to an X-axis sliding cover structure in a CNC lathe with an Y-axis added, and in particular, the tool post can be transported along the Ys axis set to have an arbitrary angle with respect to the X-axis direction and at the same time within the X-axis sliding cover. It is related to the X-axis sliding cover structure of the Y-axis CNC lathe for the Y-axis sliding cover to operate, simplifying the cover structure, improving assembly, and simplifying manufacturing.

The CNC lathe can control the tool bar for processing the workpiece in three directions: X, Y, and Z axes.

Here, the Z axis is a longitudinal direction of the bed for transferring the tool mounted on the tool bar to the chuck side clamping the workpiece, the X axis is a direction perpendicular to the Z axis to transfer the tool mounted on the tool bar on the center line of the chuck. And the Y axis indicates a direction perpendicular to the Z axis and the Y axis.

Therefore, the tool post performs feed and cutting operations while operating in the X, Y, and Z directions every time according to the machining instructions of the workpiece. In order to protect various mechanical parts and devices from coolant or chips generated during cutting, the CNC lathe is provided with a Z-axis cover, an X-axis cover, and a Y-axis cover that interlock with the traveling direction of the tool post.

Looking at the structure of the conventional X-axis cover 10 and the Y-axis cover 20 in Figure 5, they are arranged in a vertical direction with each other, these X-axis, Y-axis cover (10, 20) are respectively X-axis servo motor ( 12) and the Y-axis servo motor 14 is interlocked with the tool post 16 so as to be able to operate in a vertical direction with each other in the X, Y direction.

That is, in the case of a conventional Y-axis CNC lathe, the Y-axis cover 20 is folded or unfolded in multiple stages independently of the X-axis cover 10 when driving the Y-axis, and the Y-axis cover (when driving the X-axis ( Independent of 20), the X-axis cover 10 is also configured to perform the same operation.

Therefore, the cover structure of the conventional Y-axis CNC lathe has the following problems.

Since the X-axis and Y-axis covers 10 and 20 are arranged in a vertical direction with each other, they operate independently in a telescope type structure, so that each cover can be slid so that the manufacturing process and assembly thereof can be performed. Complex. In addition, since the cover 20, 20 should be assembled to be slidably assembled into a plurality of parts, a lot of manufacturing labor is added, and the manufacturing cost increases.

In addition, in the telescope type cover structure, durability decreases as the frequency of use increases, and the probability of failure of the cover increases due to complexity.

The present invention has been made to solve the above problems, to enable the tool post to be transported along the Ys axis set to have an arbitrary angle with respect to the X-axis direction and to operate the Ys-axis sliding cover within the X-axis sliding cover. In order to simplify the cover structure and improve the assemblability, and to provide a simple X-axis sliding cover structure of the Y-axis CNC lathe for easy manufacturing.

Specific means of the present invention for achieving the above object,

On the saddle, which is installed on the upper surface of the bed with a predetermined inclination, the tool post is placed on the saddle which can be transferred in the Z-axis direction. In the Y-axis CNC lathe to be controlled to feed in the Y-axis direction perpendicular to the

The Y-axis direction is set to the Ys axis at an acute angle with respect to the X-axis direction, and a Ys-axis cross slider having this Ys axis is installed between the tool rest and the saddle so that the tool rest is controlled by the feed of the Y-axis.

Hereinafter, with reference to the accompanying drawings will be described in detail the present invention.

First, the Y axis feed of the tool post according to the present invention is made by synchronous control of the X axis and the Ys axis set at an acute angle on the X axis as shown in FIG. 1. In the present invention, the Ys axis defines an axis having a predetermined tilt angle θ with the X axis on the X axis. That is, the Ys axis is an axis set at an acute angle with respect to the X axis. In this case, the Y axis refers to an axis having vertical coordinates with respect to the X axis and the Z axis.

Here, synchronous control means that the tool post transfers and controls the Y-axis direction by chasing the vector component of the X-axis and Y-axis simultaneously by simultaneously interlocking X-axis and Y-axis at a fixed ratio.

Referring to FIG. 2 together with FIG. 1, the following description will be made.

2 shows that when the inclination θ of the Ys axis is 30 degrees, when the Y axis is to be moved to the + Y position, the Ys axis should be moved to the + Ys position and the X axis to the -X position as shown in FIG. And the X axis is 2:- Synchronous control should be performed at the ratio of.

Here, if you want to move the Y axis to the +40 position (that is, to move the tool from the coordinates (X0, Y0) to the coordinates (X0, Y40)), the feed ratio of Y: Ys: X axis is 1: 2. :- Therefore, when Y is 40 mm, it has a conveyance amount of Ys = 80mm and X = -69.282.

Applying such a Ys-axis feed structure can be configured simply and durable X-axis cover and Ys-axis cover.

3 and 4, the saddle 60 is installed on the upper surface of the bed 52 so as to be transported in the Z axis direction, and the Ys axis cross slider 80 is disposed on the upper surface of the saddle 60 along the X axis direction. It is installed to be slidable.

The Y-axis cross slider 80 is movable in the X-axis direction according to the driving direction of the X-axis servomotor 70 fixedly mounted to the rear of the saddle 60.

Here, the Ys axis is an axis disposed to be inclined by a certain acute angle (within 90 degrees) with respect to the X axis direction of the X axis servomotor 70.

On the Ys axis, a ball screw 92 driven by a Ys axis servomotor 90 mounted to the rear end of the Ys axis cross slider 80 is disposed, and the ball screw 92 has a Ys axis cross slide 80. A tool post 16 slidably supported along the Ys axis is connected to the upper surface.

Therefore, when the X-axis servomotor 70 and the Ys-axis driving motor 90 are driven simultaneously, the tool stage 16 is transferred in the Y-axis direction perpendicular to the X-axis direction. That is, the tool post 90 determines the Y-axis feed amount by the synchronous control of the X-axis and the Y-axis.

At the rear end of the Y-axis cross slider 80, an X-axis sliding cover 100 disposed by inserting the Z-axis sliding cover 140 is fixedly arranged, and the outer surface of the X-axis sliding cover 100 is Z-axis. The sliding cover 140 is installed in contact with an inner surface of the wiper 130 to remove cutting oil and chips.

In addition, a Ys-axis sliding cover 110 sliding in the X-axis sliding cover 100 is installed at the rear end of the tool post 16. That is, one end of the Ys-axis sliding cover 110 is fixed to the tool post 16, and the other end thereof is slidably installed in the X-axis sliding cover 100.

Therefore, the Y-axis sliding cover 110 can be mounted on the inside of the X-axis sliding cover 100 while moving the Ys-axis according to the rotational direction of the Y-axis servomotor 90.

On the front surface of the X-axis sliding cover 100, the wiper for removing the cutting oil or chips attached to the outer surface of the Y-axis sliding cover 100 when the X-axis sliding cover 100 moves in the Ys-axis direction ( 120) is attached.

In addition, when the tool post 16 is moved in the X-axis direction, the Y-axis cross slider 80 is moved on the saddle 60 in the X-axis direction according to the direction in which the X-axis servomotor 70 receives and drives the command signal. .

On the other hand, the feed control of the Y-axis is made by the synchronous control of the X-axis servo motor 70 and the Ys-axis servo motor 90.

For example, when the Y-axis is moved to +40 position as shown in FIG. 2 when ?? of Ys axis is 30 degrees as shown in FIG. 1, the feed ratio of Y: Ys: X axis is 1: 2:- Therefore, when Y is 40 mm, a feed amount of Ys = 80 mm and X = -69.282 mm is required, and commands corresponding to the feed values of the Y-axis and the X-axis are Ys-axis servomotor 90 and X-axis servo, respectively. When applied as an electrical signal to the motor 70, the tool post 16 and the Ys-axis cross slider 80 move by a command value, which in turn causes the tool post 16 to travel 40 mm in the Y axis perpendicular to the X axis. Will complete.

As such, when the tool post 16 moves in the Y-axis direction, the Ys cross slider 80 and the tool post 16 are interlocked, and at the same time, the Y-axis sliding cover 110 is embedded in the X-axis sliding cover 110. It slides in and out by the amount of operation

In this way, the X-axis cover and Ys-axis cover can be configured so that the cover structure can be arranged in one direction by interlocking the Y-axis feed of the tool bar 16 with the synchronous control of the X-axis and the Ys-axis. It is easy to produce.

In addition, the cover structure is simple, so that the defective rate can be reduced, and the number of manufactured parts can be reduced by that, which can reduce the manufacturing labor.

As described above, according to the sliding cover structure of the Y-axis shelf of the present invention, the X-axis sliding cover and the Ys-axis sliding cover according to the X, Y moving direction of the tool bar can be arranged in one direction, and thus applied to the present invention. The X-axis sliding cover and the Y-axis sliding cover do not have to have a telescope structure.

Therefore, the cover structure of the present invention is an invention that is simple and contains less parts, less manufacturing work, and excellent durability.
