Abstract

PURPOSE:To promote the space saving further improve productivity, by providing a turret tool rest, movable in X axis direction (vertical direction) and indexable about horizontal axis direction-turning shaft serving as the center, in a column movable in a horizontal axis direction. CONSTITUTION:A column 4, movable in a horizontal axis direction, is mounted onto a horizontal bed 1 through horizontal guide rails 2. A work mounting headstock 5 is mounted to the bed 1 through a sliding bed 7. The column 4 comprises a turret tool rest 13, moving in X-axis direction, through a cross slide 10. Accordingly, constitution is set up such that a tool T comes to the upper surface of a work, reaction force of cutting is received as it is by an X axis guide part, and, stable cutting is performed, resulting in improvement of productivity.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a novel column type lathe.

[Conventional technology]

Conventionally, horizontal bed type lathes and slant bed type lathes are known as lathes.

[Invention! Problems to be resolved]

As mentioned above, among conventionally known lathes, horizontal bed lathes have a particularly large space and have wiring and piping in both the X and Z directions. 1'jtL. On the other hand, slant bed lathes have problems in that the turret is located far from the main spindle, resulting in poor stability, large moment l-loads due to saddle and cross slide ff[, and poor productivity due to the slanted structure. I am holding.

The purpose of the present invention was proposed in order to solve the problem in view of the above circumstances, and the purpose of the present invention is to provide a tool rest on the front side of the column so that the tool rest can be moved up and down so that the indexed tool is placed directly above the workpiece. Therefore, since the guide part that guides the tool rest up and down is configured to directly receive the reaction force of the cutting force, there is regularity and stable cutting is possible. It is an object of the present invention to provide a novel column-type lathe that is space-saving, has good stability, facilitates wiring and piping processing, and has a rectangular bed structure that provides good productivity.

[Means and operations for solving the problems] The present invention is a novel column-type lathe, and its concrete means include providing 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 and axial directions. moreover,
A loss slide is provided on the operator side of the column so as to be movable in the X-axis direction (up and down). A housing is supported on the cross slide, and the housing has a turret tool rest that can be indexed around a pivot axis in the Z-axis direction.

Thus, the present invention saves space and weight compared to conventional horizontal bed lathes and slant bed lathes, and also achieves better productivity.

〔Example〕

1) Below, one embodiment of the present invention will be explained in detail based on the drawings♀■
I'll explain myself.

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 FIGS. 1 and 2, two horizontal guide rails 2 are provided on a rectangular horizontal bed 1.

Guide g-I on the horizontal guide rail 2! A column 4 movable in the Z-axis direction is mounted via the column 3.

A headstock 5 is attached to the left side of the worker's side at the upper end of the rectangular horizontal bed 1. A main shaft 6 is rotatably supported on the headstock 5. A workpiece to be machined is attached to the front surface of the main shaft 6 via a chuck.

A sliding stand 7 is attached to the left side of the worker's side at the upper end of the rectangular horizontal bed 1 (Fig. 2), and a tailstock 8 is placed on the sliding stand 7. Along the Z-axis, the tailstock 8 is placed movably.

A center 9 is attached to the front surface of the tailstock 8, and the center 9 supports the center of the end surface of the workpiece W to be machined.

On the other hand, a cross slide 10 is attached to the front surface of the column 4 on the operator's side so as to be movable in the X-axis direction by a nervomotor 11, and a housing 12 is attached to the front surface of the cross slide 10. For chuck measurement of the housing 12, a turret tool rest 1 that can be indexed around a rotation axis in the Z-axis direction is used.
3 is installed and there are three. For example, the turret tool rest 13 is 1
It has a rectangular shape, and 10 tools T can be detachably inserted into it.

A control panel 14 and a powerful electric panel 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 column 15 extends upward and is attached to the rear end of the rectangular horizontal head 1, and a servo motor 1 is attached to the upper end of the column 15 and the top of the column 4.
A wiring piping member 17 is flexibly attached between the first attachment member 16 and the second attachment member 16 . It follows the movement of the column 4 in the X-axis direction and the cross slide 10 in the X-axis direction, and is simplified compared to conventional wiring and piping equipment, and the unidirectional F'
5; Processing is possible.

Furthermore, although not shown, the lathe of the present invention has a space on the rear surface in which a robot for sequentially transporting workpieces, A, T, C for tool exchange, etc. can be easily attached. horizontal bed 1
A chip conveyor 18 for storing chips is disposed at the lower front of the worker's side.

The present invention will be described in detail.

A work W to be machined is gripped by a spindle 6 of a headstock 5 attached to the left side of the worker's side at the upper end of a rectangular horizontal bed 1 via a chuck, and rotated by a flash drive device. The tailstock 8 is moved to the left to support the center 9 at the center of the end surface of the workpiece W. The housing 12 attached to the front of the column 4 via the cross slide 10 is
The housing 12 is moved in the axial direction and the turret tool post 13 attached to the front surface of the housing 12 is rotated to determine the tool T required for a predetermined cutting process, while the housing 12 is moved in the X and Z directions under NC control. A predetermined turning process is performed.

〔effect〕

The present invention has a structure in which a column is placed on a rectangular horizontal bed, and a droop/nod tool rest is attached to the front of the column so as to be movable in the Z-axis and X-axis directions. 6. Since it is constructed so that two tools come together, the reaction force of the cutting force can be directly received by the X-axis guide part, making it possible to obtain stable cutting.

Furthermore, since it is constructed in such a column shape, processing of wiring and piping is extremely easy, and it is effective because it saves space compared to the conventional rotary shaft.

In the present invention, the column is movably planted on a short horizontal bed, and the guide rail is installed horizontally, so the moment I and load due to the weight of the column and cross slide are reduced, resulting in high stability. , which is much better than before.

The device with one wiring and piping is flexibly installed, and processing can be performed by moving the column and cross slide in only one direction relative to the Z-axis and X-axis directions.

The 1M board of the present invention uses a short bed and column saddle shape, so it is lighter than conventional machines.

Furthermore, since the present invention allows horizontal guide rails to be arranged on the horizontal bed, it is easy to level the horizontal bed, and since each unit has a rectangular structure, it is easy to process, resulting in good productivity. be.

The chip conveyor is installed at the bottom on the operator's side, making it easier to see inside the Sennobu conveyor and check the flow of chips.

Furthermore, by using the lathe of the present invention, it is easy to construct A, T, C, etc. of the ROBONO 1-1 tool exchange for feeding one shell of a single-sided workpiece.
