Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an angle indexing jig which is used when an accessory is installed in a cylindrical container or the like.

[0002]

2. Description of the Related Art For example, in a transformer for stably supplying power energy, a tubular container is provided with a load tap switching device for keeping a secondary voltage constant. The tap change device under load may be operated by an operation panel installed outside the cylindrical container via a gear mechanism. In this case, the installation positions of the operation panel and the gear mechanism with respect to the cylindrical container are determined based on a user's request.

Conventionally, when the installation position of the operation panel with respect to a cylindrical container is set to, for example, an angle of 30 ° from the center position of the container, the angle adjustment operation is performed by adjusting one of the positions as shown in FIGS. With the pipe 2 fixed to the cylindrical container lid 1 as a reference, the other is scribed by indexing the center between the mounting holes 3 and 3 of the container lid 1 with a steel ruler, and scribed between the scribe line and the pipe 2. A thread 5 is stretched via a weight 4 and is mounted on the head of a gear mechanism 7 for driving a load tap switching device 6 based on the stretched thread 5 as shown in FIGS. 6 and 7. 8, the drive shaft 9 of the gear mechanism 7 is set at a position at an angle of 30 °, and the set drive shaft 9 is set.
To the operation panel (not shown).

[0004]

In the conventional angle adjusting operation shown in FIG. 6, the labor of the worker is required for a minute because of the absence of the angle reference position on the container lid 1. Therefore, there were some problems and inconveniences in the work.

[0005] (1) As described above, the center is indexed visually by an operator using a steel rule between the mounting holes 3 and 3 in the angle setting operation. Since the thread 5 is stretched on the basis of the error, the operation panel deviates from a predetermined position, so that it is necessary to readjust the center indexing, and there is a problem that a lot of work time is spent. .

(2) Also, the angle setting work of another container lid 1 of the same kind requires a large amount of work time since the operator performs the indexing work of the center, and when the delivery time of the product is short, other production is required. There was a problem that hindered the process.

(3) Further, in the angle adjustment work largely depending on the labor work of the worker, the work is not adapted to the mass production system, and this has hindered the improvement of the productivity.

The present invention has been made in view of the above circumstances. In setting an angle, even if there is no container lid or the like that determines a reference position, it can be easily and quickly mounted accurately. It is an object to provide an angle indexing jig capable of setting an angle.

[0009]

In order to achieve the above object, an angle indexing jig according to the present invention has a plate having a scale on an edge and two ends of the plate. A support plate formed integrally and continuously on the side and extending in the cross direction, a guide groove formed along the scale of the plate, and an object that slides along the guide groove and requires an angle setting And a scale indicating plate incorporating an adapter that moves in synchronization with the object.

In order to achieve the above object, in the angle indexing jig according to the present invention, the plate is formed in a semicircular shape.

In order to achieve the above object, the angle indexing jig according to the present invention, as set forth in claim 3, has a plate and a support plate formed in a thin plate shape. Positioning and fixing are performed using bolt holes in the container lid.

According to a fourth aspect of the present invention, there is provided an angle indexing jig according to the present invention, wherein the scale indicating plate includes a guide roller that slides in a guide groove and an angle setting object. A locking screw that locks onto the scaled plate when it is in position.

In order to achieve the above object, in the angle indexing jig according to the present invention, the adapter is formed in a box shape having one end opened.

According to a sixth aspect of the present invention, there is provided an angle indexing jig according to the present invention, wherein the adapter covers a drive shaft of an object requiring an angle setting, and a scale. It is configured to fit into a notch formed in the indicator plate.
