Abstract

PURPOSE:To contrive the movement of a mounting member in its orthogonal two directions by providing a connecting member being able to turn about a shaft and unable to move in the axial direction in a moving shaft able to move reciprocating and inserting a connecting shaft to be slidably fitted to the connecting member. CONSTITUTION:A mounting member 1 is provided being able to move on a plane in a supporting member 9 through a sliding plate 10. The supporting member 9 provides a moving shaft 11 reciprocatably by a rack shaft 17, mounting connecting member 18 turnably while movable with the moving shaft 11. A turn lever 24 is swivelably mounted in an orthogonal direction with a moving direction of the moving shaft 11 to a supporting block 23 mounted to a bottom surface of the mounting member 1, and a connecting shaft 22, provided in the turn lever 24, is slidably inserted to the connecting member 18. A pull up bolt 26, penetrating through the turn lever 24, is fixed to the connecting member 18. Accordingly, when the moving shaft 11 moves reciprocating, even the turn lever 24 reciprocates as an integral unit, reciprocating also the mounting member 1, and when it is moved in the othogonal direction, the connecting shaft 22 is slided turning the connecting member 18.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an orthogonal bidirectional movement mechanism used for mounting members such as machine tools, X-Y tables, and mounting stands for drill grinding devices.

[Conventional technology]

Conventionally, this type of orthogonal two-direction moving mechanism includes an intermediate member provided on a supporting member so as to be movable and guided by a first guide mechanism in one of the two orthogonal directions of the moving member, and an intermediate member provided on the supporting member. A structure in which a moving member is provided so as to be movable and guided in the other moving direction by a second guide mechanism is known.

[Problem to be solved by the invention]

However, in the case of the conventional uIt structure mentioned above, two types of guide mechanisms, the first and second, are required, and two guide surfaces are required, resulting in a complicated structure, which has disadvantages in terms of manufacturing cost and miniaturization. are doing.

[Means to solve the problem]

The present invention aims to solve these disadvantages, and its gist is to provide a mechanism that can move and guide a mounting member in two orthogonal directions, and to enable the mounting member to be moved in a plane on a support member. a moving shaft is provided on the supporting member so as to be movable in one direction of movement of the mounting member; a shaft moving mechanism is provided for reciprocating the moving shaft; the connecting member is rotatable around the moving shaft; a connecting shaft is provided on the mounting member so as to be movable in one direction; , a moving mechanism that allows the mounting member to move in one moving direction and pushes the mounting member in the other moving direction; The orthogonal two-direction moving mechanism is characterized in that it is provided with a return mechanism that moves the mounting member back in the other moving direction when the mounting member is not pushed.

[Effect]

When the moving shaft is reciprocated by the shaft moving mechanism, the moving force is transmitted to the mounting member via the connecting member and the connecting shaft, and the moving shaft reciprocates in one direction of movement, and at this time pushes the mounting member in the other direction of movement. The moving mechanism allows the mounting member to move in one direction, and the return mechanism moves the mounting member in the other direction when the moving mechanism pushes the mounting member in the other direction. When the mounting member is moved back in the other direction of movement, the connecting shaft swings in the other direction of movement of the mounting member and slides on the connection member, allowing movement of the mounting member in the other direction of movement.
