Description

本発明は、ベースに取付け可能としたワークのワーク取付け具に関する。 The present invention relates to a workpiece attachment tool for a workpiece that can be attached to a base.

従来、クランプ冶具を利用してベースにワークを係止する(クランプとする)場合は、ベースの端より突出した部位(端部とする)にクランプ本体を取付け、このクランプ本体に設けた爪を介してワークの適所を締付ける構成となっている。勿論、爪を自動クランプする構造もある。このようなクランプ冶具では、板形状のワークには適するが、嵩高の角材、パイプ材、チャンネル鋼材等の場合には、クランプ又は位置決めに難渋すること、またクランプ又は位置決めの不備による加工不良が発生すること等の弊害が考えられる。このような場合、従来は、適宜の位置決めブロック等を介在して、ワークの位置決めをする手法が取られていた。しかし、この手法では、厄介であること、必ずしも正確な位置決めができず、加工途中でワークが動くことが考えられる。従って、簡易に位置決め及び/又は取扱いが容易な位置決め冶具が要求される処である。   Conventionally, when a workpiece is locked to a base using a clamp jig (to be used as a clamp), the clamp body is attached to a portion protruding from the end of the base (to be used as an end), and the claws provided on the clamp body are attached. It is configured to tighten the appropriate position of the work through. Of course, there is a structure for automatically clamping the claws. Such a clamp jig is suitable for plate-shaped workpieces, but in the case of bulky squares, pipes, channel steel, etc., it is difficult to clamp or position, and defective machining due to incomplete clamping or positioning occurs. It can be considered harmful to do so. In such a case, conventionally, a technique for positioning a workpiece with an appropriate positioning block or the like has been employed. However, with this method, it is troublesome, and accurate positioning is not always possible, and it is conceivable that the workpiece moves during machining. Therefore, a positioning jig that is easily positioned and / or easily handled is required.

尚、文献で位置決め冶具として有用と考えられる発明があるので、以下に説明する。この発明を文献(1)とする。この文献(1)は、特開2004−142036の「クランプ装置」であり、その概要は、クランプ本体は、立設した本体部と、この本体部に所定距離をおいて立設したクランプ部と、この本体部とクランプ部を連結する連結部で構成し、この本体部を肉厚で、かつ略矩形のブロック形態とし、またクランプ部を肉薄で、かつ傾斜形態とする。そして、この本体部とクランプ部に段差を介して空間を形成し、この空間に挿入した移動体を螺子止め及び/又は圧入することで、前記クランプ部を撓ませながら、緊締する構成である。従って、簡略な構造をもって、ワークを確実かつ安定的にクランプできること、ワークが保持されるべきベースに簡単かつ迅速に取付け得ること、又は優れた使用性と、汎用性が図れること等の特徴がある。   In addition, since there exists invention considered to be useful as a positioning jig by literature, it demonstrates below. This invention is referred to as document (1). This document (1) is a “clamp device” disclosed in Japanese Patent Application Laid-Open No. 2004-142036. The outline of the clamp body is that a clamp main body is a standing main body portion, and a clamp portion is provided at a predetermined distance from the main body portion. The main body portion and the clamp portion are connected to each other, and the main body portion has a thick and substantially rectangular block shape, and the clamp portion has a thin and inclined shape. Then, a space is formed in the main body portion and the clamp portion through a step, and the movable body inserted into the space is screwed and / or press-fitted to tighten the clamp portion while bending the clamp portion. Therefore, there are features such as that the workpiece can be reliably and stably clamped with a simple structure, can be easily and quickly attached to the base on which the workpiece is to be held, or has excellent usability and versatility. .

特開平2004−142036JP 2004-142036

文献(1)は、クランプ本体を、本体部と、この本体部に所定距離をおいて設けたクランプ部で構成し、このクランプ部が撓むことを利用してワークの位置決めをする構成である。しかし、クランプ部の動きが不安定であり、必ずしもワークを安定して位置決めするとの保証がないと考えられる。殊に、ベースに設けたワークを加工する状況下で、加工の際に、加工冶具の切削、研磨等の作業で、ワークにおもわぬ押圧及び/又は荷重がかかった場合に、このワークが容易に移動する虞がある。またこの文献(1)は、ベースにボルトを利用してクランプ本体を取付ける構成であるので、ベースに新たな加工を要すること、又はベースの場所によっては、このクランプ本体を取付けることができないこと等の問題があり、またこの問題を解決しない限り、汎用性の面で問題を残すと思われる。   Document (1) is a configuration in which a clamp main body is composed of a main body portion and a clamp portion provided at a predetermined distance from the main body portion, and the workpiece is positioned using the bending of the clamp portion. . However, the movement of the clamp part is unstable, and it is considered that there is no guarantee that the workpiece is positioned stably. In particular, when a workpiece provided on the base is being machined, when the workpiece is subjected to pressing and / or load other than the workpiece due to cutting, polishing, etc. of the processing jig, the workpiece is easy. There is a risk of moving to. Moreover, since this literature (1) is the structure which attaches a clamp main body using a volt | bolt to a base, a new process is required for a base, or this clamp main body cannot be attached depending on the place of a base, etc. Unless this problem is solved, it seems that the problem remains in terms of versatility.
