本考案は、ハンマ、ハンマドリル等の中間子を
有する打撃工具の寿命に関するものである。[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to the lifespan of impact tools such as hammers and hammer drills having an intermediate member.
工具と打撃子の中間に設けた中間子にオイルシ
ールを有して潤滑剤を密封して、先端工具に打撃
を与える電気ハンマ等の一部構造を第１図に示
す。
FIG. 1 shows a partial structure of an electric hammer, etc., which has an oil seal in an intermediate element provided between the tool and the striking element to seal in lubricant to apply a strike to the tip tool.
中間子１１の先端工具１、ハンマホルダ１４、
フロントカバ２との接触部は、シリンダケース１
３の中に入つている潤滑剤をオイルシール８，
９，１０によつて密封されているため無潤滑とな
つている。従つて、中間子は先端工具の繰り返し
の衝突と往復運動に耐える強度を有している必要
がある。 Tip tool 1 of intermediate child 11, hammer holder 14,
The contact part with the front cover 2 is the cylinder case 1.
Transfer the lubricant contained in 3 to the oil seal 8,
9 and 10, so there is no lubrication. Therefore, the meson needs to have the strength to withstand repeated collisions and reciprocating motions of the tip tool.
しかし、前記の無潤滑状態と作業時のコンクリ
ート粉、衝突時の繰り返し応力と先端工具の往復
運動により、時間が立つにつれて中間子の各部品
との摺動部が摩耗して寿命低下の現象が出る。 However, due to the above-mentioned unlubricated condition, concrete powder during work, repeated stress during collisions, and reciprocating motion of the tip tool, the sliding parts of the meson and the various parts will wear out over time, resulting in a shortened lifespan. .
本考案の目的は、上記した中間子の各部品との
摺動部の摩耗を少なくして、この種の打撃工具の
寿命を長くすることである。
The purpose of the present invention is to reduce the wear of the sliding parts of the above-mentioned meson and the various parts, and to extend the life of this type of impact tool.
本考案は先端工具を打撃する時、打撃しない時

係を工夫したものである。
This invention focuses on the fact that the intermediate moves left and right when the tip tool is struck and when it is not struck, and the front cover, oil tank chamber, felt, and oil spigot are designed so that oil is appropriately supplied into the front cover. This is a devised version of the relationship.
本考案の実施例を第１図、第２図により説明す
る。
An embodiment of the present invention will be explained with reference to FIGS. 1 and 2.
第１図は先端工具１に中間子１１を介して打撃
子１２によつて打撃を与え、被加工物をこわす電
気ハンマの一部構造図である。 FIG. 1 is a partial structural diagram of an electric hammer that breaks a workpiece by applying a blow to the tip tool 1 with a striker 12 via an intermediate member 11.
シリンダケース１３内の潤滑剤はオイルシール

イルタンク室１５を設け、フロントカバ内にカイ
ル６がフエルト５によつて供給されるようにして
ある。フエルト５の位置は打撃時に中間子１１の
先端工具１の打撃端面の前方、中間子が前方に往
し出された時に中間子の後端部になるように設定
してある（第２図参照）。 The lubricant in the cylinder case 13 is prevented from leaking into or out of the front cover by oil seals 8, 9, and 10. An oil tank chamber 15 is provided on the outer periphery of the front cover 2, and a kiln 6 is supplied into the front cover by a felt 5. The position of the felt 5 is set so that it is in front of the striking end surface of the tip tool 1 of the intermediate member 11 during impact, and at the rear end of the intermediate member when the intermediate member is advanced forward (see FIG. 2).
以上のような構成において、中間子の移動によ
