Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a groove blowpipe arrangement setting device for setting the arrangement of a groove blowpipe in a predetermined state during groove processing.

[Conventional technology]

Conventionally, workers have adjusted the grooved blowpipe empirically and made trial cuts to determine the correct position.

[Problem that the invention attempts to solve]

However, with the conventional placement setting method described above, it is extremely rare for the grooved blowpipe to be placed correctly with a single adjustment, and several trial cuts and corrections are required, resulting in the complaint that it is time-consuming and labor-intensive. be.

For this reason, various groove blowpipe arrangement setting devices have been devised, but those with a simple structure are functionally inferior and difficult to handle, and they are difficult to accurately and quickly set the groove blowpipe to the desired state. However, the ones that are not able to be used and have excellent functions have the problem that they are expensive and require troublesome maintenance.

[Means for solving problems]

The present invention includes a base plate having a first coupling means, a horizontal reference line, and a horizontal guide parallel to the horizontal reference line, and an arcuate guide, and the center of the arcuate guide is disposed on the side of the horizontal reference line. a slider movably attached to the horizontal guide of the base plate; a movable member having a second coupling means and a pointer, the pointer being disposed at a radial position of the arcuate guide and movably attached to the arcuate guide; By providing this, the above-mentioned conventional problems are solved.

[Effect]

While moving the slider relative to the base plate, moving the movable member along the arcuate guide of the slider,
The pointer of the movable member intersects the horizontal reference line of the base plate at the desired position and angle. In this case, after the base plate is connected to the reference member such as the central blowpipe of the groove cutting block by the first connecting means, the groove blowpipe is moved relative to the reference member and the second movable member is connected to the base plate.
They are connected by a connecting means, and in this state, the grooved blowpipe is fixed integrally with the reference member. After that, the connection between the base plate and the movable member to the reference member and the groove blowpipe by the first coupling means and the second coupling means is released, and the arrangement setting of the groove blowpipe is completed.
