Description

[Detailed Description of the Invention] The present invention relates to a device for checking the operation of an intermediate stopper.

When a stopper is used to stop a shuttle table that transfers and positions a workpiece to each processing position of machine tools arranged in parallel at predetermined intervals, a device for checking the operation of the stopper as shown in Figure 1 has conventionally been used. . That is, the engagement block 3 is attached to the side surface of the slide table 2 that moves forward and backward on the base 1.
A cylinder 5 is provided on the side of the base 1.
and a piston rod 7 which is integrated with a piston 6 fitted into the cylinder 5 so as to be slidable in the vertical direction, and which the engagement block 3 comes into contact with as it moves upward.
One end of a horizontal bracket 8 perpendicular to the axis of the piston rod 7 is fixed to the lower end of the piston rod 7, and the other end has a bracket 8 that stands up parallel to the axis of the piston rod 7. A dog bar 9 is attached, a dog 10 is provided on this dog bar 9, and this dog 1 is attached.
Confirmation limit switch 1 operated by 0
1 is arranged on the side of the base 1.

Therefore, in such an operation checking device, chips falling from above may accumulate on the checking limit switch 11 and the checking operation may become unstable. I try to cover it with a cover. By the way, since the base 1 on which the checking limit switch 11 is installed is located between a pair of machine tools facing each other, there is not a large work space on the sides of the base 1, and it is difficult to remove the cover and remove the cover when adjusting the dog. There was a problem that the adjustment work of the dog could not be done easily.

In view of the above-mentioned conventional problems, the present invention solves the conventional drawbacks by arranging the checking limit switch at a position where it is difficult for chips to accumulate and where dog adjustment can be easily performed. Embodiments of the present invention will be described below with reference to FIGS. 2 to 4.

In Figures 2 and 3, 1 is the base, 2
is a slide table that moves forward and backward on the base 1 by an actuator (not shown). An engagement block 3 that comes into contact with a stopper, which will be described later, is fixed on the side surface of the slide table 2.

On the other hand, an intermediate stopper 4 is installed on the side surface of the base 1 on the same side as the side on which the engagement block 3 is fixedly installed. This midway stop stopper 4
is integrated with a cylinder 5 and a piston 6 fitted into the cylinder 5 so as to be slidable in the vertical direction,
It consists of a piston rod 7 (stopper) with which the engagement block 3 comes into contact as it moves upward.

In the above structure, the present invention provides a rack 12 in the axial direction of the piston rod 7, and a pivot shaft 13 is rotatably supported on the base 1 along an axis perpendicular to the axis of the piston rod 7. A pinion 14 that meshes with the rack 12 is provided at one end. Furthermore, a swing lever 15 is provided at the other end of the pivot shaft 13 in a direction perpendicular to the axis of the pivot shaft 13 .

Further, one end of an operating rod 17, which is arranged to be movable in the moving direction of the slide table 2, is connected to the swing lever 15 via a connecting rod 16, as shown in FIG. The other end of the operating rod 17 projects outward from the rear end of the base 1, and a dog 18 is adjustably attached to it.

The base 1 from which the other end of the operating rod 17 protrudes
A bracket 20 is fixed to the rear end surface, and a confirmation limit switch 19 operated by the dog 18 is disposed on the bracket 20.

Since the present invention has the above-mentioned structure, the vertical movement of the piston rod 7 is achieved by moving the operating rod 17 in its axial direction by means of a motion conversion mechanism consisting of the rack 12, pinion 14, pivot shaft 13, and swing lever 15. The check limit switch 19 is operated by the dog 18.

Therefore, according to the present invention, the confirmation limit switch is disposed at the rear end of the base far away from the part of the stopper, and is activated by remote control using the piston rod, that is, the movement conversion mechanism of the stopper, and the operating rod. This prevents chips from accumulating on the confirmation limit switch mounting part even without a cover, providing stable operation and making it easy to adjust the dog. .
