Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a positioning device for positioning H steel, which is used when the H steel is subjected to predetermined processing.

[0002]

2. Description of the Related Art Conventionally, for example, when a column for construction is manufactured by subjecting H steel to a work such as welding, the work such as welding is performed while the H steel is positioned by a positioning device. Is common.

FIG. 2 shows the configuration of the above-mentioned conventional positioning device.

In FIG. 2, a is a level block on which the H steel W is placed, and the flange surface W is placed on the level block a.
One flange surface W1 is placed so that 1 is the top and bottom.

Reference numeral b is a positioning block which is erected on the side of the level block a, and each end surface of the upper and lower flange surfaces W1 of the H steel W contacts the contact surface b1 of the positioning block b.

A clamp cylinder c is provided on the opposite side of the positioning block b across the level block a. The clamp cylinder c is for clamping the H steel W placed on the level block a with the positioning block b. Specifically, the clamp cylinder c is extended so that the abutting member c1 at the tip is moved to the web surface W2 of the H steel W.
The upper and lower flange surfaces W1 of the H steel W are pressed against the positioning block b to position the H steel W.

[0007]

However, in the above-mentioned conventional positioning device, the H steel W is positioned by pressing the respective end surfaces of the upper and lower flange surfaces W1 of the H steel W against the positioning block b. There was such a problem.

That is, since the H steel is positioned with reference to the respective end surfaces of the upper and lower flange surfaces W1, the H steel has a positional accuracy variation due to variations in the product of the flange surface W1. There was a problem that the position of the parts was misaligned during the application and the product accuracy could not be maintained.

The present invention has been made in view of the above problems. An object of the present invention is to position the H steel on the basis of a web surface having a relatively small product variation, thereby positioning accuracy of the H steel. It is to provide a positioning device for H steel that can improve the product quality and maintain high product accuracy.

[0010]

H of the invention according to claim 1
The steel positioning device is a positioning device for positioning the H steel in order to perform a predetermined process on the H steel, and abuts against a level block on which one flange surface of the H steel is placed and a web surface of the H steel. It is provided with a positioning member and a clamping means for pressing the web surface against the positioning member to clamp the H steel.

In the H steel positioning device of the second aspect of the present invention, the positioning member is an adjusting bolt.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows the construction of the H steel positioning device of the present invention.

In FIG. 1, reference numeral 1 denotes a level block on which H steel W is placed, which is stably fixed to a floor surface by bolts 11. On the level block 1, one side of the flange surface W1 is arranged vertically. The flange surface W1 of is placed. Thereby, the H steel W is arranged so that the web surface W2 is erected.

Reference numeral 2 is a mounting block which is erected on the side of the level block 1, and an adjusting bolt 21 as a positioning member is mounted on the mounting block 2. Specifically, a concave mounting hole 22 is provided in the middle of the mounting block 2.
Is formed, and the mounting plate 23 is inserted in the mounting hole 22.
Are provided over the top and bottom.

The adjusting bolt 2 is attached to the mounting plate 23.
For example, two 1 are screwed into the upper and lower portions. The adjusting bolt 21 is a portion whose head portion 21a abuts the web surface W2, and is arranged by being screwed in such that the head portion 21a protrudes from the mounting plate 23 by a predetermined length, and is fixed by a nut 21b from the back side. Has been done. Therefore, by changing the amount of screwing of the adjusting bolt 21 into the mounting plate 23, the position where the H steel W abuts can be adjusted at any time.

Further, the mounting block 2 is provided with a recessed escape hole 24 vertically in order to avoid interference with the end faces of the upper and lower flanges W2 when positioning the H steel.

On the other hand, a clamp cylinder 3 as a clamping means is provided on the opposite side of the mounting block 2 with the level block 1 interposed therebetween. The clamp cylinder 3 is
The purpose is to clamp the H steel W placed on the level block 1 with the adjusting bolt 21. Specifically, the clamp cylinder 3 is horizontally arranged on the support member 32 so that the expandable rod 31 of the clamp cylinder 3 approaches and separates from the adjust bolt 21, and a contact member provided at the tip of the expandable rod 31. 33 is configured to contact the web surface W2 of the H steel W placed on the level block 1 from the opposite side of the adjusting bolt 21.

Next, the case where the H steel W is positioned by the H steel positioning device thus configured will be described.

First, the H steel W is placed on the level block 1 so that the web surface W2 is placed vertically. Then, the clamp cylinder 3 is extended to bring its abutting member 33 into contact with the web surface W2 of the H steel W, and the clamp cylinder 3 is further extended to press the web surface W2 against the head portion 21a of the adjusting bolt 21. As a result, the H steel W is arranged on the level block 1 at a position adjusted in advance by the adjusting bolt 21, and is clamped while being positioned by the adjusting bolt 21 and the clamp cylinder 3.

After positioning the H steel W on the level block 1 in this manner, appropriate parts are arranged at predetermined positions and subjected to welding or other processing.

As described above, in the H steel positioning device of the present invention, the H steel W is applied to the web surface W with less product variation.
Since the positioning is performed on the basis of 2, the positioning accuracy of the H steel W can be improved, thereby maintaining the accuracy of the product manufactured by processing the H steel W such as welding the parts at a high level. be able to.

[0023]

As described above, according to the H-steel positioning device of the present invention, the H-steel is positioned by bringing the web surface with less product variation into contact with the abutting member to position the H-steel. It is possible to improve the positioning accuracy of the H steel, and by doing so, it is possible to maintain the accuracy of the product manufactured by subjecting the H steel to processing such as welding of parts at a high level.

Further, by forming the contact member with the adjusting bolt, the contact position can be adjusted, and by adjusting it as necessary, high positioning accuracy can be maintained.
