Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transfer type machine tool device in which at least two unit machine tools are arranged side by side on the left and right and a workpiece is sequentially machined with one unit machine tool and then with the other unit machine tool.

Conventionally, this type of device has the disadvantage that if two unit machine tools are installed side by side on the left and right sides, a relatively large space is taken up as a whole.

The object of the present invention is to obtain an apparatus that does not have such inconveniences, and the workpieces are sequentially placed at one non-processing position and two processing positions equiangularly spaced on a substantially rectangular base. A unit in which an index table for selection is provided, a V-shaped column is provided that intersects perpendicularly at the rear on a line connecting the non-processing position and the center of the table, and a processing unit is arranged in front of the column so as to be vertically movable. A workpiece in which at least two machine tools are arranged side by side so that adjacent columns are located on a straight line, and the center of rotation is at the intersection of the line connecting the non-processing position and the table center between the adjacent unit machine tools. It comprises a conveying means.

Embodiments of the present invention will be described with reference to the attached drawings.

In the drawings, reference numeral 1 indicates a unit machine tool, and at least two of the machines 1 are prepared and these are sequentially installed in parallel.

FIG. 1 shows the case with two devices, and FIG. 2 shows the case with three devices.

Each unit machine tool 1 consists of a substantially rectangular base 2 as a whole, and is equipped with an index table 5 having three rotatable chuck units 4 on the circumference on the top surface of the base 2 to removably hold a workpiece 3. According to the operation of the table 5, each workpiece 3, together with each chuck unit 4, can be freely selected between two left and right machining positions 6, 6 at the rear, and one non-machining position 7 at the front. The base 2 is provided with a generally square-shaped column 8 extending upward along both left and right edges at the rear of the base 2, and on the front side thereof are vertical molds facing the two left and right machining positions 6, 6. A pair of left and right processing units 9, 9 are arranged side by side.

At each machining position 6, each cheek unit 4 is connected to a drive spindle on the lower side and rotates N with the workpiece 3, and each machining unit 9, 9 has a cutter tool at its lower end via a tool post 10. The cutter 10a is of a protruding type, and thus the cutter 10a acts on the rotating workpiece 3 to cut it.

For example, two of the unit machine tools 1 are arranged side by side in a pair on the left and right as shown in the first figure. The left and right columns 8, 8 are arranged approximately parallel to each other, so that the left and right columns 8, 8 are continuous with each other at their inner ends to form a generally U-shaped surrounding frame that is open to the front. I made it.

Further, a conveying means 11 is provided at a forward position of the intermediate dissection, and acts to convey the workpiece 3 between one non-processing position 7 and the other non-processing position 7.

The conveyance stage 11 is further configured to guide the workpiece 3 between a pair of conveyors 12, 12 on the inlet side and the outlet side. It was provided that they could be guided in sequence to position 7 and then to the other non-processing position I: then onto the other conveyor 12.

In the embodiment shown in the second figure, three of these units are installed in parallel as described above, and in this case, the three units extend over a range of approximately 270 degrees on the circumference, and from each column 8, 8, 8 on the outer periphery. The conveying means 11 is arranged in the center of the frame.

To explain its operation with respect to the one shown in the first diagram, workpiece 3
is sequentially guided to the non-machining position 7 on one unit machine tool 1 and then to the two left and right machine positions 6, 6 behind it, and after being processed by each unit 8, 8, the non-machining position 7 is position 7
is installed at the non-machining position I in the other unit machine tool 1, and then guided to the left and right machining positions 6, 6 behind it and processed by each machining unit 8, 8, and then the non-machining position in front of it is It is returned to the processing position 7 and prepared for removal, and this is performed for each workpiece 3 one after another.

In this way, according to the present invention, the machine tool is provided with an index table for sequentially selecting workpieces at one non-processing position and two processing positions equiangularly spaced on a substantially rectangular base; A V-shaped column is provided that intersects perpendicularly at the rear of the line connecting the processing position and the center of the table, and a force unit is disposed in front of the column so as to be able to move up and down.
The machining unit can obtain a highly rigid machine tool that does not overhang the workpiece, and at least two adjacent columns of the unit machine tool are arranged in parallel so that they are located on a straight line, and the adjacent Since it is equipped with a workpiece transport means whose rotation center is at the intersection of the line connecting the non-processing position and the center of the table in the middle of the unit machine tool, the non-processing position of each machine tool is from the rotation center of the workpiece transport means. The distances to the centers of the workpieces are the same, and the actuating arm of the workpiece conveyance means is guided to each conveyance position sequentially without expanding or contracting, which greatly facilitates the arrangement of the workpiece lead-in/exit section. This has the advantage that the device can be arranged within a relatively small area.
