Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a novel column type lathe.

[Conventional technology]

Conventionally, a slant bed type lathe which is a horizontal bed type lathe is known as a lathe.

[Problems to be solved by the invention]

As described above, among the conventionally known lathes, the horizontal bed type lathe is particularly complicated because it has a large space and the wiring and pipe processing has X and Z directions, respectively. On the other hand, in the slant bed type lathe, the position of the tool post is far from the main spindle,
It suffers from poor stability, large moment load due to the weight of the saddle and cross slide, and poor productivity due to the inclined structure.

The object of the present invention was proposed in order to solve the problem in view of the above circumstances, and provided on the front side of the column so that the tool rest can be moved up and down so that the indexed tool comes directly above the work. Therefore, since the guide portion that guides the tool rest up and down is provided with the structure that can receive the reaction force of the cutting force as it is, it has rigidity and enables stable cutting. It is an object of the present invention to provide a new column-type lathe which is space-saving, has good stability, is easy to handle wiring and piping, and has a rectangular bed structure, which has good productivity.

[Means and Actions for Solving Problems]

The present invention is a novel column-type lathe, the specific means of which is to provide a horizontal guide rail on a rectangular horizontal bed. A column is provided on the horizontal guide rail so as to be movable in the Z-axis direction. Further, a cross slide movable in the X-axis direction (vertical direction) is slidably provided on the operator side of the column. A housing is supported by the cross slide, and the housing is provided with a turret tool post that can be indexed around a turning axis in the Z-axis direction.

Thus, the present invention saves space and is lighter in weight than conventional horizontal bed lathes and slant bed lathes, and further improves productivity.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a front view of the present invention, and FIG. 2 is a view taken in the direction of arrow I in FIG.

In FIG. 1 and FIG. 2, two horizontal guide rails 2 are provided on a rectangular horizontal bed 1. A column 4 movable in the Z-axis direction is placed on the horizontal guide rail 2 via a guide portion 3.

A headstock 5 is attached to the left side of the operator's side at the upper end of a rectangular horizontal bed 1. A spindle 6 is rotatably supported on the spindle stock 5. A work to be machined is attached to the front surface of the spindle 6 through a check.

A slide base 7 is attached to the left side of the operator side at the upper end of the rectangular horizontal bed 1 (FIG. 2), and a tailstock 8 is installed on the slide base 7, and along the slide base 7. The tailstock 8 is mounted so as to be movable in the Z-axis direction. A center 9 is attached to the front surface of the tailstock 8, and the center 9 is a work W to be machined.
Support the center of the end face of.

On the other hand, a cross slide 10 is attached to the front surface of the column 4 on the operator side so as to be movable in the X-axis direction by a servomotor 11, and a housing 12 is attached to the front surface of the cross slide 10. On the chuck side of the housing 12, a turret tool post 1 that can be indexed around a turning axis in the Z-axis direction
3 is attached. The turret tool post 13 has, for example, a decagonal shape, and ten tools T are detachably inserted therein.

A control board 14 and a strong electric board are arranged on the back side of the rectangular horizontal bed 1, and each device for controlling and driving the lathe of the present invention is built therein. A pillar 15 is attached to the rear end of the rectangular horizontal bed 1 so as to extend upward, and wiring is provided between the upper end of the pillar 15 and the mounting member 16 of the servomotor 11 mounted on the upper portion of the column 4. The piping member 17 is flexibly attached. It flexibly follows the movement of the column 4 in the Z-axis direction and the movement of the cross slide 10 in the X-axis, and is simpler than the conventional wiring and piping apparatus, and can be processed in one direction.

Further, on the back surface of the lathe according to the present invention, although not shown, there is a space for easily mounting a work transfer robot, a tool changing ATC, or the like. A chip conveyor 18 for storing chips in the lower front part of the operator side of the horizontal bed 1.
Is provided.

The operation of the present invention will be described.

A workpiece W to be processed is held by a spindle 6 of a spindle stock 5 mounted on the left side of the operator at the upper end of a rectangular horizontal bed 1 and is rotated by a drive device (not shown). The tailstock 8 is moved to the left to support the center 9 at the center of the end surface of the work W. The housing 12 mounted on the front surface of the column 4 via the cross slide 10
While moving in the axial direction and turning the turret tool post 13 mounted on the front surface of the housing 12 to index the tool T required for a predetermined cutting process, the NC-controlled movement of the housing 12 in the X and Z directions is performed. A predetermined turning process is performed.

〔effect〕

According to the present invention, the column is installed on the rectangular horizontal bed, and the turret tool post is attached to the front surface of the column so as to be movable in the Z-axis and X-axis directions. Since it is configured as described above, the reaction force of the cutting force can be directly received by the X-axis guide portion, and stable cutting can be obtained.

In addition, since such a column type is constructed, the processing of wiring and piping is extremely easy, and space saving is effective compared with the conventional lathe, which is effective.

According to the present invention, since the guide rails are installed horizontally in order to movably move the column on the rectangular horizontal bed, the moment load due to the weight of the column and the cross slide is reduced, and thus the stability is high, and it is higher than the conventional one. It will improve significantly.

Wiring and piping devices are flexibly attached, and processing can be performed only by moving the column and cross slide in one direction with respect to the Z-axis and X-axis directions.

Since the lathe of the present invention adopts the rectangular bed and the saddle shape of the column, the weight can be reduced as compared with the conventional one.

Further, according to the present invention, since the horizontal guide rails can be arranged on the horizontal bed, the leveling of the horizontal bed is facilitated, and since each unit has a rectangular structure, the machining is facilitated, and thus the productivity is good.

Since the chip conveyor is provided on the lower side of the operator side, the inside of the chip conveyor can be easily seen and the flow condition of the chips can be easily checked.

Further, by using the lathe according to the present invention, it is easy to construct a robot for transferring a work, an ATC for tool exchange, etc. from the back side.
