【発明の詳細な説明】
本発明は、物品を固定的に保持するための方法
に関し、特にバリ取り加工等を受ける物品を任意
の姿勢で自在に保持するのに適した方法に関す
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for fixedly holding an article, and more particularly to a method suitable for freely holding an article to be deburred or the like in any posture.
従来、定型的に量産品のバリ取り等の加工作業
を行なう場合は、専用の固定治具が準備されてい
るが、単品または極く少ロツトの場合は、それぞ

ど固定治具を交換するか、または別に治具を容易
せずに床に置いたまま、作業を行なつていた。 Traditionally, special fixing jigs have been prepared for routine machining operations such as deburring mass-produced products, but in the case of single items or extremely small lots, the sizes and shapes of the jigs often differ. Therefore, the fixing jig had to be replaced each time, or the jig had to be left on the floor as work was carried out.

ある。 However, with the fixed jig replacement method, there is a problem that the preparation time for jig replacement is longer than the time required for work such as deburring, reducing efficiency. There is a risk that the object may move due to the reaction force from the grinder, etc., and when reversing or changing the position of the object, a lift, chain block, or lever operation is required, which does not improve efficiency. There is a problem. Particularly if the item is left on the floor, it is nearly impossible to automate the work using a robot or remote control, and in this case a jig for fixing the item is essential.
本発明は、物品の保持に伴う上述の諸問題を解
決しようとするもので、簡単な操作により物品の
保持を能率よく且つ自在に行なえるようにした方
法を提供することを目的とする。 The present invention aims to solve the above-mentioned problems associated with holding articles, and it is an object of the present invention to provide a method that allows articles to be held efficiently and freely through simple operations.
