JPS5871014A - Gang head attaching and removing device - Google Patents

Abstract

PURPOSE:To simplify the operation of a gang head attaching and removing device, by enabling a gang head on rails to be attached and removed between a pedestal and the rails only in such a manner that a supporting bed 6 is vertically moved and as well a hook is moved back and forth. CONSTITUTION:A gang head 1 is suspended from annular rails 3. When a hook 9 advances and a supporting bed 6 moves upward, the head 1 is pushed and therefore lifted so that the head 1 is disengaged from the rails 3 and the hook 9 engages with a projection 1a on the lower surface of the head 1. When the hook 9 is moved reaward, the head 1 is taken out from the rails 3 onto a pedestal 5. Thus, the gang head is transferred between the rails and the pedestal.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for attaching and removing the spatula V, which is mainly applied to a machine tool with a replaceable gigang head. Conventionally, in this type of machine tool, the gigang head was supported in a suspended manner on an annular rail, and Prepare multiple pieces around the circumference,
A type in which any one of the gearing heads can be freely moved to an operating position is known.1 Furthermore, in this type, any one of the gearing heads can be removed from the rail and replaced with a separate gearing head. has also been proposed, but in this case, the head should be attached and detached t4'V, f1 from the outside of the lift table or other pedestal, and it is preferable that this can be done simply and easily.

The object of the present invention is to obtain a device that meets such requirements.A supporting stand extending below the gearing head is mounted on a lifting stand or other pedestal outside the gearing head, and is moved up and down by a rear cylinder. It is provided with seven vines on its upper surface which can be freely engaged with the m-c-s under the head and can be met by a shift cylinder.

An example of implementing the present invention will be explained with reference to the attached drawings.

The drawing shows a machine tool with an exchangeable gigang head (11 indicates the gigang head, and the head (1) is suspended from an annular rail (3) on the outer periphery of the processing unit (2). ~ Prepared in multiple pieces on the outer periphery, and rotated on the index table (4) above it so that any one piece can be freely placed in the operating position on the front side,
In this way, it was possible to prepare for machining the workpiece island in front of it. The ganging head (1) is taken out from the rail (3) in its rear inactive position onto a vertically movable pedestal (5) on its back side and replaced with a separate ganging head (1) above it. 1 To be more specific, the pedestal (5) is moved up with the gearing head (1), and in the upper position, the head 11) is connected to the other head (1) prepared separately in advance. The head is replaced, and then the other head (1
)E, the gag head (1) should be moved onto the rail (3), and according to the present invention, the gag head (1) is constructed as follows in preparation for attachment and detachment. .

That is, as shown in Fig. S, the lower side of the gearing head (1) on the annular rail (3) (extending support base (6) and lever 7) is interlocked with the cylinder (7) on the pedestal (5). The front and rear 97) links (8 bars 8) allow the head to be raised and lowered freely, and the protrusion (1) on the lower surface of the head (1) is placed on the support stand (6).
4 shifts of 7 gears (9) that can be freely engaged with a) cylinder a.
Support rollers αυ are arranged in parallel on both front and rear sides of the support rollers in multiple stages on both front and rear sides.

To explain its operation, it is assumed that the first gear head (1) is suspended on the annular rail (3), and in this state, the footer (9) is advanced and the support base (6) is moved upward. For example, the head (1) is pushed and lifted by this, disengaging from the rail (3), and the hook (9) becomes engaged with the protrusion (1&) on its lower surface. , Next, if wA7tsuk (9) is retired, the head (
1) is pulled by this and moves backward on the support base (6), and thus the head (1) moves from above the rail (3) to the base (5).
) To return the head (1) to the 0th order, which is taken out above, the footer (9) is moved forward and the support base (6) is moved downward. It is pushed forward and moved downward to be engaged with the rail (3).

This operation is performed by the upper separate gearing head (1) mentioned above.
) is also approximately the same, that is, the separate gearing heads (1) are placed on the separate lIK rail <6&) on the upper side of the annular rail (3) described above, and are arranged in a painter's style at multiple locations on the outer periphery. This is the pedestal (5) mentioned above.
It can be attached to and detached from the pedestal (5) in substantially the same way by setting it to the upward movement position. The pedestal (53 is, for example, a motor α2
1 pair of left and right guide rails A4 via chain A3e
1 It is a type that moves up and down guided by a41.

In this way, when climbing the present invention, the gearing head on the rail can be attached to and detached from the pedestal by simply moving the support platform i up and down and moving it back and forth seven times, making the head replacement work simple and easy. It is easy to use, its structure is simple, and it has an advantageous effect on cost.

Claims (1)

[Claims] On the outside of the gearing head, on the other pedestal, a support base extending below the head is provided so as to be movable up and down using a lift cylinder, and on its upper surface, a hook that can be held on the lower surface of the head can be moved back and forth using a shift cylinder.
