PURPOSE:To shift a drilling position exactly by providing a piece screwed to a rotary screw shaft and moving along with the forward and reverse rotation of the shaft with a stopper for positioning a workpiece. CONSTITUTION:A rotary screw shaft 1 is supported so as to be rotated freely by a bearing 7 with the axis faced on the transferential direction of a workpiece (a) transfered by a conveyor 6. This rotary screw shaft 1 is screwed by a piece 3, which can be moved back and forth in the transferential direction of the workpiece (a) along with the forward and reverse rotation of the rotary screw shaft 1. And the piece 3 is provided with a stopper 4 for positioning the work piece (a) by contacting with the end of the workpiece (a). A drill 5 is provided at the upper stream side of the transferential direction of the workpiece (a) than the position of this stopper 4. By thus constituting a drilling device, the moving quantity of the stopper 4, that is, the shifting quentity of a drilling position can be enlarged and controlled readily.

Description

[Detailed Description of the Invention] [Technical Field 1] The present invention relates to a drilling device for drilling a hole in a workpiece, and more specifically, it is an object of the present invention to accurately change the drilling position while increasing the degree of freedom in changing the drilling position. related to technology.

[Background Art] Conventionally, the position of drilling a hole in a workpiece transported by a transporting device is changed by changing the position of the workpiece in the transporting direction. For example, it is possible to change the position of the stopper using a shilling, but when changing the position of the stopper using a shilling, the larger the amount of change, the larger the stroke. 6 is required, and if the amount of change is to be considerably large, there is a problem that Schilling is too expensive.

[Object of the invention 1 The present invention has been made in view of such problems,
The purpose of this is to create a perforation that can increase the amount of change in the stopper's position, has a relatively simple configuration, reduces costs, and allows for easy control of position changes. The goal is to provide equipment.

[Disclosure of the Invention J The present invention provides a forward-reverse rotation electric motor that rotatably bears a rotary screw pongee 1 whose axis is directed in the conveying direction of a workpiece a, and that drives and rotates the rotary screw pongee 1 in forward and reverse directions. 2 are interlocked and connected to the rotary screw pongee 1, and the pj3 moves in the forward and backward direction of the transport direction of the workpiece a as the rotary screw pongee 1 rotates forward and backward. A stopper 4 is provided for positioning the workpiece, and a perforation ρ rill 5 is provided upstream of the stopper 4 in the workpiece conveyance direction. By configuring in this way,
The above objectives have been achieved. In other words, the rotating screw shaft 1
By rotating forward and backward, the piece 3 screwed onto the rotating screw shaft 2
1 to be able to move the striker and collar 4 in the forward and backward direction of the conveyance direction of the workpiece a.
Therefore, it is easy to increase the amount of movement of the stopper 4 (the amount of change in the drilling position) compared to Schilling, and the cost can be reduced compared to cylinders, etc.
Moreover, the control can be performed simply and easily.

Embodiments of the present invention will be described in detail below based on the drawings.

A rotary screw pongee 1 is rotatably supported by a bearing 7 with its axis oriented in the direction of conveyance of a workpiece a conveyed by a belt conveyor 6. A forward/reverse rotating electric motor 2 capable of forward/reverse rotation is interlocked and connected to the downstream end of the rotating screw pongee 1 in the workpiece conveying direction. It is a DC servo motor.

In addition, the rotating screw tsumugi 1 is a ball screw tsumugi, but the design can be changed in various ways such as a regular screw tsumugi or a square screw shaft. The pieces 3 can be moved in the forward and backward directions in the conveyance direction of the 7-a as the pieces 1 rotate in the forward and reverse directions. The piece 3 is provided with a stopper 4 that comes into contact with the tip of the workpiece a to position the workpiece a. A drilling drill 5 is provided upstream of the stopper 4 in the workpiece transport direction. This drilling drill 5 has a driller 5a replaceably attached to its tip, and the driller 5a is attached to the main body of the drilling drill 5.
4:5 The part a is raised and lowered so that the workpiece a on the belt holder 6 can be drilled. The main body of the drilling drill 5 is fixed to a bearing 7. In addition, piece 3 is held movably up and down by an up/down shilling-8, and #3,
Rotating screw pongee 1, forward/reverse electric rotating motor 2, and drilling drill 5
It is possible to raise and lower the stopper 4 by raising and lowering it with a lifting sill-8. In order to raise and lower the stopper 4 in this way, in the embodiment, the entire body including the rotary screw shaft 1 is raised and lowered, but by rotating the piece 3 around the rotary screw pongee 1 at a certain angle, the stopper 4 can be moved up and down. Various design changes are possible, such as making the stopper 4 rise from the belt conveyor 6 by swinging it in a direction perpendicular to the paper plane of FIG. Further, the elevating shilling 8 travels together with the pieces 3 along a traveling guide (not shown).

According to such a configuration, by driving and rotating the forward/reverse electric rotary motor 2 based on the control signal and rotating the rotary screw pongee 1 in the forward and reverse directions, the piece 3 screwed onto the rotary screw pongee 2 is rotated in the front and rear directions of the workpiece conveyance direction. Then, the stopper 4 attached to the piece 3 is moved forward and backward in the transport direction of the workpiece a, the position of the stopper 4 relative to the workpiece a is changed, and the drilling position thereof is changed. That is, the workpiece a is slightly inserted using the belt conveyor 6, the workpiece a is positioned by the stopper 4 at the position indicated by the solid line, and a hole is drilled using the perforation drill 5.
Next, the forward/reverse electric rotary motor 2 is rotated a certain number of times based on the control signal to move the stopper 4 to the broken line position, the belt conveyor 6 is started, the workpiece a is brought into contact with the stopper 4, and positioning is performed, and the workpiece a is positioned again. After drilling with the drilling drill 5 and making a plurality of holes at predetermined positions in this way,
The stopper 4 is raised by the lift 8 and the workpiece a is carried out. When the unloading is completed, the forward/reverse electric rotary motor 2 is controlled to rotate according to the control signal, and the stopper 4 is returned to the original fixed position (1).

[Effects of the Invention] In short, the present invention provides a piece that is screwed onto a rotary screw pongee which is rotated in forward and reverse drive and moves in the forward and backward direction of the conveyance direction of the workpiece in accordance with the forward and reverse rotation of the rotary screw pongee. Since there is a stopper that comes into contact with the stopper to position the workpiece, by rotating the rotary screw shaft forward and backward, the stopper attached to the piece screwed onto the rotary screw pongee can be moved forward and backward in the transport direction of the workpiece. It is easier to increase the amount of movement of the stopper (the amount of change in the drilling position) than with a Schilling, but it is also cost-effective compared to a Schilling, etc., and its control can be controlled using a forward-reverse rotating electric motor. It has the advantage of being simple and easy to use.
