Abstract

PURPOSE:To reduce the shift stroke length, improve the positional accuracy of a work and improve the operability by performing a parallel movement in the prescribed shifting direction via the X link mechanism consisting of the 1st link and 2nd link which are attached tunably at the center point each other. CONSTITUTION:An X link mechanism 7 is composed so that the connection line connecting the fulcrums 9a, 9b of both ends of the 1st link 9 at the intermediate position of the shift stroke of a fitting base 2a and the connection line connecting the fulcrums 10a, 10b of both ends of the 2nd link l0 are located on the same plane in Y axial direction. The stroke between the advance end position and retreat end position can therefore be made 1/2. With the device of this composition, the positioning accuracy of a work and working efficiency can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of application on cheeks) The present invention particularly relates to a shifting device for a jig used for spreading water to a bathing station.

(Prior art) Conventionally, when shifting a jig on a machine stand, the entire mounting base of the jig is supported on the machine stand via guide members such as guide bars and guide rails so that it can move parallel to the shifting direction. I try to do that.

(Problem that %mei tries to solve) In the above, it is necessary to attach the guide member to the machine base with high rigidity, and the size of the entire 4-door member, including the mounting frame, has increased. In addition, when performing welding work, melting spatter may cause bamboo debris to be deposited on the welding member, which may interfere with the shifting operation of the jig.

In this case, it may be possible to omit the guide member by supporting the mounting base of the jig on the turret via the In the forward path position, between the fixed fulcrum at one end of the link composing the rocky shore i4 and the mounting base of the other link: (cross) the fixed fork point at one end of the link, and - The distance in the shift direction between the sliding fulcrum at the other end of the ten thousand link with respect to the mounting base and the sliding fulcrum of the other end of the other link with respect to the machine base becomes longer, and the fixed fulcrum of the orthogonal cutting edge and the sliding The distance to the fulcrum becomes shorter, and the support rigidity of the mounting base decreases.
There is a problem that the positioning accuracy of the workpiece held in the jig becomes poor.

It is an object of the present invention to provide a shift device having a small IM, light weight, and high support rigidity, which solves the problem of the gap in the X-link mechanism.

(Means for solving the problem) Unexpectedly, it is a jig shift device installed on one machine to achieve the above purpose, and is it a jig mounting base? On the nuclear machine,
In a device that is supported parallel to a predetermined shift direction via an X-link depression Ik consisting of a first link and a second link that are pivotally connected to each other at their midpoints, the
The connection between the fixed fulcrum at one end of the first link relative to the machine base and the slide fulcrum at the other end relative to the mounting base, the fixed fulcrum at one end of the second link relative to the mounting base, and the It is characterized in that the connection with the slide fulcrum at the other end is made so as to be located on the same planar concave perpendicular to the shift direction at an intermediate position of the shift stroke of the mounting base.

(Function) At the intermediate position of the shift stroke, the connection between the fulcrums at both ends of the first link and the connection between the fulcrums at both ends of the second link are the same.
Located on the flat surface, the X177 mechanism is in its most contracted state, so even if the shift stroke is lengthened, the shift direction between the identification fulcrums of the single link and the second link and the slide fulcrums at the forward end position will not change. The distance between the fixed fulcrum of the 1st link on the machine side and the sliding fulcrum of the 2nd link, and the fixed fulcrum of the 2nd link on the mounting base side and the sliding fulcrum of the 1st link. A relatively long distance can be secured between the two, and the support rigidity of the mounting base can be increased.

Also, at the % rearward end position, the fulcrums on the mounting base side move backward in the shift direction than the fulcrums on the side, making it compact with the mounting base and the X17 link mechanism intertwined. When transporting workpieces by moving and holding the trench and machine base, the stability of the machine base and jig may be reduced as above, resulting in high-speed IW.
This is advantageous because it allows the workpiece to be transported easily.
