Abstract

PURPOSE:To aim at the promotion of labor-saving and efficiency, by making the machining of multisurfaces of a work performable simultaneously or continuously. CONSTITUTION:A rotary table 4 is indexibly installed in an index table 2, while an index shaft is inserted coaxially through inside the table 4, and plural index tables 10 are rotatably set up in the rotary table 4 at equal angles. And, each of these tables 10 and index shafts are coupled together at each commensurate position via an index mechanism having the same indexing angle. Therefore, when a drill unit C exists in the central position in its machining range D, drilling to a tip end face W1 of a work W comes possible to be done. When the drill unit C is situated in an ascending position, machining to four sides W2-W5 of the work W can be performed. At the same time, even at the descending position of the unit C, machining to four sides W6-W9 can be done. Therefore, machining for nine sides in total to one work comes possible to be done. In addition, machining for multisurfaces is thus possible simultaneously or continuously.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an index and apparatus for multi-face machining that is capable of simultaneous or continuous multi-face machining.

In recent years, with the development of long-distance machine tools, mechanical equipment oriented toward unmanned operation has been developed, and more and more machines are being combined with multiple mechanical devices to create unmanned equipment such as VMS (flexible manufacturing systems) and processing cells. Development of ='A
It is in. Under these circumstances, the problem is how to set up the workpiece efficiently and without manpower, and this depends on the performance of the workpiece mounting jig, especially the quality of its indexing function. it is conceivable that.

Based on this idea, the present invention aims to provide an indexing device for multi-face machining that is particularly suitable for multi-face machining of small parts.

In the indexing device for multi-face processing according to the present invention, a rotary table is attached to the index table so as to be indexable, the concentric centers of the indexing axes are inserted into the rotary table, and ten indexing tables are attached to the rotary table. The indexing table and the indexing shaft are arranged under equal angles so as to rotate freely, and the indexing mechanism having the same indexing angle is connected to the indexing table at each corresponding position. Hereinafter, one embodiment of the present invention will be described with reference to all the drawings.

FIG. 1 is an external perspective view of an indexing device for multi-face machining according to the present invention, which is indicated by tt-symbol (5), and a workpiece (S'V ffi) for machining is shown opposite to this device. The automatic processing device is indicated by the symbol (131).The processing device (
Reference numeral 131 shows one for drilling, as an example.

The indexing device (4) for multi-face machining is equipped with an index table (2) and a bearing on the base (1)! (31t are arranged facing each other, and a rotary table (4) is installed between them so as to be indexable, and the indexing shaft (5) is inserted concentrically into the rotary table (4) as shown in Fig. 2. ing.

One end of the indexing shaft (5) is supported by a bearing device (3) to support -f4 of the loading table (4), and the other end is pushed through the index table f2). It is connected to a motor (7) with a reduction gear (6). One end of the rotary table (4) is attached to the indexing shaft (5) as described above.
), but the other end is an index table (2)
is supported by an indexing disc (8). (9)
is an indexing motor attached to the index table (2), which performs indexing by rotating the rotary table (4) by 90° in the direction of the arrow (a) via the indexing disk (8). It looks like this. The indexing shaft (5) passes through the center of the indexing disc (8) and is connected to the indexing motor.

On the loaf 1 table (4), several indexing tables (10) for indexing the workpiece (5) are rotatably arranged at predetermined intervals, and each indexing table (
10) and the front IC indexing shaft (5) are connected to each other at six positions through indexing machine grooves having the same indexing angle, as will be described later. This rotary table (4
) is formed into a rectangular cylinder with four right-angled metal faces, but its shape can be changed in various ways depending on the relationship between its indexing angle and the angle of the machined surface of the workpiece. It is.

In the following, for convenience, the case of a tetrahedron shown in the figure will be explained.

The indexing table (10) is attached to each side of the rotary table (47) at equal angles of 90°.In addition, the indexing table (10) is attached to each side of the rotary table (47) at an equal angle of 90°. are also arranged at predetermined intervals. However, this condition is not necessarily absolute (
It should be arbitrarily rejected without any effort. Further, all the index tables (10) are simultaneously converted at a predetermined index angle in the direction of the arrow (bl) by rotation of the common index shaft (5). The workpiece (5) is mounted on (1o) directly or via other suitable fixtures (not shown).

Drill unit for drilling holes in workpiece (5))
(5 is installed in the processing device (Bl) as necessary, and can be moved up and down within a predetermined range in the illustrated embodiment.

Further, referring to FIGS. 2 and 6, the base end of each separate table (10) and the indexing shaft (5) are connected to the indexing mechanism consisting of a bevel gear (
11). That is, all the bevel gears (12) attached to the indexing table (10)
The gears mesh simultaneously around the bevel gear (13) attached to the indexing shaft (5), and in this embodiment, at least the bevel gears (12) are all the same. The same applies to the gear (16). It is not necessarily necessary that the bevel gears (12) and (13) t be the same. Also, index table (1tl)'fr
If it is necessary to divide into groups of several hammers in the longitudinal direction, it will be necessary to change the modules, number of teeth, etc. of the bevel gears (12) and (13) so that each group has a different indexing angle. However, even in such cases,
The gear trains in the circumferential direction of the rotary table (4) are configured to have the same indexing angle.

Although the indexing mechanism (11)) has been described above using a mechanical bevel gear, it goes without saying that the indexing mechanism (11) is not limited to this.

Although the indexing mechanism in the index table (2) is not shown in the figure, it is possible to use a mechanism similar to the one described above or other cam machines (such as 4). This is the coupling (5).

In this embodiment, the rotary table (4) & the index table (2J) are used to convert the index table (10) by 90 degrees.At each conversion position, the index table (10) attached to each surface is connected to the common index axis. (5) can be converted into a predetermined angle via the bevel gears (13) and (12).For example, the index table (
10) The indexing angle of 90" is the same as the rotary table.
Then, as shown in Fig. 4, 22 drills M (1''-
Its machining range (if it is at the center position of 0, the workpiece (5)
It is possible to drill holes on the tip surface (W□) of the workpiece (drill unit)
5) The four sides (W2AVs) can be processed. Similarly, the workpiece (22 drills) (at the lowered position of Q)
It is possible to process the four sides (W6-W, ) of b). Therefore, a total of 9 surfaces are machined for one workpiece.
1 becomes possible. In this way, it is possible to carry out multifaceted processing on one workpiece, and moreover, it can be carried out simultaneously or consecutively.

As described above, according to the present invention, multifaceted processing of a workpiece can be performed simultaneously or continuously, resulting in significant labor savings and
Streamlining can pay off. Therefore, its significance is especially great for unmanned work equipment.
