Description

[Detailed Description of the Invention] The present invention relates to a device for preventing scattering of chips and the like in an index table type machine tool.

Conventionally, this type of machine tool has been equipped with a plurality of chuck units that removably hold a workpiece on an index table above the machine stand, and each unit is attached to at least one chuck unit in front of the machine.
A type is known in which the workpiece attachment/detachment position and at least two rear workpiece processing positions on the left and right can be selected sequentially, and each processing position is further provided with each processing unit facing the unit. However, in this case, the table is generally equipped with a partition plate around its outer periphery to prevent chips etc. from scattering to the outside. At least in the above-mentioned workpiece loading/unloading position, it is necessary to open the workpiece to the front in preparation for the loading/unloading operation.In other words, the partition plate is not provided at the front, and there is an inconvenience that scattering prevention is not performed. .

The purpose of the present invention is to obtain a device that does not have such inconveniences.
A plurality of chuck units 4 for removably holding the workpiece 3 are disposed above, and each unit 4 is attached to at least one chuck unit in front.
Workpiece loading and unloading positions A, and at least two workpiece machining positions B, B on the left and right at the rear can be configured sequentially and freely, and each machining unit 5 facing the unit 4 is arranged in each machining position B. In the equipped type, each partition plate 6 is provided on the table 2 and extends between each two of the chuck units 4 and 4.

The drawing shows a case where two machine tools are installed side by side, and each one has a chuck unit 40 on the table 2 on its upper surface.
The partition plate 6 is made up of three radial plates, which are connected to each other at the ends and are integrally formed.

In this case, the workbench I is fixedly placed on the upper surface of the workbench I, and the operator stands on it to prepare for tool replacement or repair of the machining unit 5, if necessary.

In the illustrated example, each machine 1 has a substantially rectangular shape as a whole;
A column 8 extending upward is formed in approximately the rear half of the column 8 and has a V-shaped cross section, and each processing unit 5 is provided on the inner surface of the column 8 in the vertical direction.

In the drawing, numeral 9 indicates a loader that introduces and extracts the workpiece 3.

To explain its operation, according to the operation of the index table 2, each chuck unit 4 carries each workpiece 3.
The intermediate chuck unit 4, which operates in this manner, has partitions on its art material side. A plate 6.6 exists and is isolated from each chuck unit 4.4 adjacent thereto, and thus each machining position B.

B are mutually protected from scattering of chips or cutting fluid, etc., and the attachment/detachment position A is also approximately the same as each adjacent machining position B,
It is protected from the scattering of chips etc. from B, and the attachment/detachment position A
has an open front surface, so there is no problem in introducing and extracting the workpiece 3.

In this way, according to the present invention, index table 2
It is provided with each partition plate 6 located between each two adjacent chuck units 4°4 above, and the workpiece straightening position A is the reciprocal of chips etc. generated at each workpiece machining position B adjacent to this. Since the front surface is open, there is no problem in introducing and extracting the workpiece 3, and thus there is no inconvenience of the conventional method described above, and the structure is simple and has the advantage of being inexpensive.
