JPS58149152A - Rotary positioning device for columnar work - Google Patents

Abstract

PURPOSE:To simplify facilities and improve positioning accuracy by dividing the turning and positioning processes for a work on its mechanism. CONSTITUTION:The pressing and fixing device 14 of a columnar work 10 is provided with a pressing plate 30 fixed in its position and another pressing plate 31 capable of being moved toward and apart from said pressing plate. A shaft 32 projected from the pressing plate 31 is supported on a pedestal 34 via a bearing 33. The pedestal 34 is connected to the piston rod of an air cylinder 35, while it is engaged with guide plates 36 on both sides movably in only linear motion along the expansion direction of the cylinder 35. A shaft 43 projected from the pressing plate 30 is a rotary driving shaft. This shaft 43 is engaged with the output gear 48 of a motor 47 via a gear 46. Thus the structure is simplified and positioning accuracy is improved.

Description

[Detailed description of the invention] The present invention is directed to a rotational positioning device for a one-column workpiece.

This conventional design +1111 has a columnar shape ψ as shown in Figure 1.
- A pair of chuck mechanisms (!) ν(sl) and a rotary drive machine 411f41t of ten thousand chuck mechanisms (!) are provided at both ends of the longitudinal direction of the chuck mechanism (3). 15. In this case, both the rotation of the workpiece (1) and the positioning of the workpiece +1) are performed in the chucked state.

The workpiece (1) is set by inserting (6) and chuck (@).
, pressing (7), and chuck (8).

Collection is done with the opposite wishes. In other words, the workability of setting and unloading is not very good. father,
The chuck machine 4I has a high mK.

The larger the work, the more costs will be required for the locking mechanism.

The present invention solves the problem of the via' amount, and by treating the workpiece as a workpiece with a thorn-shaped object, by mechanically differentiating it from (1) rotation of the workpiece and positioning of the workpiece.
■ The workpiece is square. 1. (In other words, it is a flat surface that is stably stationary) By effectively using it as a positioning element, 2.) It requires less capital investment than the conventional chuck mechanism. The purpose is to provide a relatively efficient and accurate positioning action in addition to the burden t.

To achieve this objective, the technical means or gist of KXJIIF'A are the same as those in the following sections fI) and (5). In order to facilitate understanding, Figures 8 to 11 show this primitive structure as well as its operation.
84 causes [Mixture with reference.

However, it should be noted that the present invention is not in any way limited by these illustrations.

(Engineer) Elevating the mounting table I for the columnar work 4 device w1 @, the columnar work - t The columnar work is placed on the above-mentioned mounting table u1) which clamps it from the direction intersecting the longitudinal direction of the columnar work.

The effects of the configurations (1) and (1) are as follows.

(4) It is divided into 6 parts: rotation of the workpiece and positioning of the workpiece. That is, the rotation lii is the pressing fixing device α
It depends on the arrival and rotation ￥Ut (to). The positioning is
The mounting table 1 is moved up and down *Wa2, and a holding device is used. Compared to the conventional one with chuck mechanism T+,
Although the device points increase to 1, the individual devices are 4!14 easy.

Can handle even large workpieces.

Therefore, overall, the burden on the equipment role will be reduced compared to the past.

(2) The property of the workpiece being angular and flat, allowing it to stand still stably on a single mounting table, is effectively utilized as a single positioning element.

For cutting, it is necessary to determine the stopping height of the mounting table and to position the workpiece in the cross direction with respect to the workman's hands, and these are the methods of binding and binding that are simple in structure and have high positioning accuracy.

(C) Place the workpiece set on the mounting table tlllK and set it aside. Anal ejaculation is also extremely easy.

Thus, the effects of the present invention can be described as follows.

B) Equipment investment burden is easy to reduce to 1 (B) Rank 11
