Description

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

In recent years, with the development of NC machine tools, mechanical equipment that is oriented toward unmanned operation has been developed. Development towards – on trend. Under these circumstances, the problem is how to efficiently set up workpieces without manpower, and this depends on the performance of the workpiece mounting jig, especially the quality of its indexing function. It is considered that I.
31. 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. A table is mounted so as to be indexable, an indexing shaft is inserted concentrically into the rotary table, a plurality of indexing tables are rotatably disposed at equal angles on the rotary table, and the indexing table is rotatably arranged at equal angles. and the indexing shaft are connected to each other via an indexing mechanism having the same indexing angle at respective corresponding positions.

An embodiment of the present invention will be described below with reference to the drawings. - Fig. 1 is a perspective view of the external appearance of an indexing device for multi-face machining according to the present invention, and this device is designated by the reference numeral (4); The processing device is indicated by the symbol (B). The processing device (B) is shown as one for drilling holes, for example.・The indexing device (4) for multi-face machining has an index table (
2) and a bearing device (3) are arranged facing each other, a rotary table (4) is mounted between them so as to be indexable, and an indexing shaft (5) is installed in this rotary table (4) as shown in FIG.
) are inserted concentrically.

One end of the indexing shaft (5) is supported by a bearing device (3) to support one end of the rotary table (4),
The other end is inserted through the index table (2) and the reducer (
6) is connected to the attached motor (7). One end of the rotary table (4) is supported by the indexing shaft (5) as described above, while the other end is supported by the indexing disk (8) of the index table (2). (9) is an indexing motor attached to the index table (2), which connects the rotary table (4) via the indexing disk (8).
) is rotated 90 degrees in the direction of the arrows (,) for indexing. The indexing shaft (5) is inserted through the center of the indexing disk (8) and connected to the indexing motor (7).
) is connected.

The rotary table (4) has a plurality of indexing tables (10) rotatably arranged at predetermined intervals for indexing the workpiece (g), and each indexing table member and the The extraction shaft (5) is connected at each corresponding position via an indexing mechanism having the same indexing angle as described later.As is clear from the figure, this rotary table (4) has four right-angled sides. It is formed into a rectangular cylindrical body with a diameter of 40 mm, but this shape can be changed in various ways depending on the relationship between its index angle and the angle of the machined surface of the workpiece. This will be explained using the case of a face piece.

Indexing tables αQ are mounted on each side of this rotary table (4) at equal angles of 90°. In addition, the rotary table (4) is also arranged at predetermined intervals in the longitudinal direction of the rotary table (4) in order to enable simultaneous or continuous processing of a large number of pieces. However, this honor is not necessarily absolute;
It should be selected arbitrarily. Further, the indexing table (10 is a common index t, 5) by which all the indexing tables (2) are simultaneously converted at a predetermined indexing angle in the direction of the arrow (b) by rotation of the shaft (5); A workpiece (6) is mounted on the indexing table α1 directly or via another suitable jig (not shown).

Trill unit for drilling holes in the workpiece (5)
(C) Multiple rows if necessary, the above processing equipment (B)
In the illustrated embodiment, it is possible to move up and down within a predetermined range.

Further, referring to FIGS. 2 and 6, the base end of each side table (11m) and the indexing shaft (5) are connected to the indexing mechanism I consisting of a bevel gear at the corresponding position.
are related by. That is, all the bevel gears a3 attached to the indexing table (11) are in mesh with the bevel gear <13 attached to the indexing shaft (5) at the same time, and in this embodiment, at least the bevel gear All fJ2 are the same, and the same is true for bevel gear 0.

It is not necessarily necessary that the bevel gears α2 and ul are also the same. If it is necessary to divide the indexing table M into several groups in the longitudinal direction, the bevel gear Q2. It will be necessary to change the α3 module, number of teeth, etc. However, even in such a case, the gear train in the circumferential direction of the rotary table (4) is configured to have the same index angle.

Although the case where the indexing mechanism opening υ is formed by a bevel gear has been described above, it goes without saying that the invention is not limited to this.

Although the indexing mechanism in the index table (2) is not shown, the same mechanism as in the above case or other cam lateral grooves or the like may be used.

I in the figure is a coupling of the indexing shaft (5).

In this embodiment, the rotary table (4) is transformed by 90° by the index table (2). At each conversion position, the angle 1 can be converted to a predetermined angle via the bevel gears tti and u3 by rotation of the common indexing shaft (5) on the indexing table attached to each surface. For example, Index Tates.

If the indexing angle of the tool aO is 90° as in the rotary table, when the drill unit (C) is at the center position of its machining range as shown in Fig. , ) is possible, and when the drill unit) (C) is in the raised position, the workpiece shift 4
Processing can be performed on two sides (Wt~w, l).

Similarly, in the lowered position of the drill unit (C), the workpiece (6
) can be processed on the four sides (w1 to We).

Therefore, it is possible to process nine surfaces in total for one workpiece. In this way, it is possible to perform multifaceted processing on one workpiece, and moreover, it is possible to perform multifaceted processing 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
You can improve efficiency. Therefore, it is of great significance especially in unmanned machining equipment.
