Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a workpiece positioning and supporting device for positioning a workpiece placed on the upper surface of a supporting device main body at a predetermined position.

[Prior art]

Conventionally, when positioning multiple types of workpieces with different reference hole positions and pitches using a common support device, a dowel pin was provided on a movable member that was supported and guided so as to be movable in a predetermined direction on the device body. A mechanism has been adopted in which the position and pitch of the dowel pin can be changed by disposing a support member so as to be orthogonally movable and guiding the movement of the support member on the movable member. However, such a mechanism requires a double sliding structure in order to move the support member in a secondary direction in a plane parallel to the support surface of the workpiece. For this reason, not only does the structure become complicated, but since there are two guide surfaces for the movable member, there are many places where metal chips adhere, and cleaning work thereon becomes labor-intensive.

[Purpose of invention]

The purpose of this invention is to solve the above problems,
Provided is a positioning support device that can change the position and pitch of a dowel pin by guiding and supporting a movable member provided with a dowel pin with a simple structure using a unidirectional guiding means, thereby eliminating the places where metal chips adhere. The goal is to minimize it as much as possible.

[Structure of the idea]

In order to achieve the above object, the present invention includes a movable case that is slidably assembled along one side of the support device body, and a positioning means that slides the movable case and positions it at a predetermined adjustment position. , a rotating shaft rotatably mounted vertically inside the movable case, and a knock pin integrally provided at the upper end of the rotating shaft eccentrically from the axis of the rotating shaft; It is an object of the present invention to provide a workpiece positioning and supporting device in which the knock pin is engaged with a reference hole of a workpiece placed on the upper surface.

〔effect〕

The positioning support device having the above structure is characterized in that the position of the knock pin can be changed by rotating the rotating shaft, thereby simplifying the guiding means for the movable case and By limiting the guide surface to only one direction, it is possible to minimize the number of locations where metal chips adhere.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. The workpiece positioning and supporting device 10 shown in FIG. A pair of movable cases 20, 20 with two parallel guide rails 12, 12 fixed to one side of 11 and slidably guided and supported by these guide rails 12, 12.
It is equipped with Each movable case 20 is threadedly engaged with a feed screw 21 driven by each servo motor M1 fixed to both sides of the support device main body 11, and is slid widely in the direction of the arrow shown in the figure by rotation of the feed screw 21. It is positioned and fixed at that sliding position. Also,
Inside each movable case 20, a rotary shaft 22 is rotatably mounted vertically, and a knock pin 23 is integrally provided at the upper end protrusion of the rotary shaft 22. In this case, the knock pin 23 is located eccentrically by a distance α from the axis of the rotary shaft 22, as clearly shown in FIG. Thereby, the position of the knock pin 23 can be adjusted by rotating the rotary shaft 22. Note that the rotation of the rotating shaft 22 is brought about by meshing a worm 25 with a worm wheel 24 provided on the rotating shaft 22 and driving the worm 25 by a servo motor M2 fixed to the movable case 20. Also, reference numerals 11a and 11a in the figure
indicates a seat pad fixed to the upper surface of the support device main body 11, and numerals 20a and 20a indicate each movable case 2.
The seat pad is shown fixed to the top surface of the 0.

In the positioning support device configured as described above, the workpiece W placed on the support device main body 11 is
According to the position and pitch of the reference hole provided on the lower surface of the servo motor M1, the distance between the movable cases 20, 20 is adjusted by driving each servo motor M1, and the rotating shaft 22 is rotated by driving each servo motor M2. The position and pitch of the knock pin 23 are adjusted according to the rotation angle. Through such adjustment operations, a plurality of types of workpieces having different reference hole positions and pitches can be positioned and fixed on the common support device main body 11. In addition, in the above example,
Although an example has been described in which the pair of movable cases 20, 20 are both slidably provided, it may also be implemented in such a way that one of the movable cases is fixed and only the other movable case is adjusted in position.

[Effects of Examples]

As can be understood from the above description, the main feature of the above embodiment is that the position of the knock pin 23 can be changed by rotating the rotating shaft 22, and thereby the movable case 20 can be guided. The means (guide rails 12, 12) can be simplified, and the guide surface thereof can be limited to only one direction, so that the number of places where metal chips are attached can be minimized.
