Abstract

PURPOSE:To aim at improvement in positioning accuracy, by installing a first member provided with the recessed part installing along two straight lines to be orthogonalized, and also a second member installing a projecting part to be opposed to it and driving toward the first member. CONSTITUTION:A first member 1 provided with two sets of triangular drill-form recessed parts 1a and 1b installed each along two straight lines to be orthogonalized is installed there. In addition, a second member 3 provided with a convex part to be engaged with these recessed parts 1a and 1b at a position being opposed to the former. The first member 1 is roughly positioned, and when the second member 3 is driven toward the first member 1, these recessed parts 1a and 1b of the first member 1 is made so as to be accurately engaged with the projecting part of the second member 3, thus a position of the first member 1 is remedied, therefore it is subject to pressure-contact at an accurate position and strongly clamped.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a positioning clamp mechanism, and relates to a positioning clamping mechanism for positioning and clamping a movable pallet, etc., in a transfer machine, etc., to a predetermined position for each workstation, for example. Regarding the clamp mechanism.

[Prior Art] In such a conventional positioning clamp mechanism, a positioning mechanism using, for example, a combination of a positioning pin and a positioning hole, and a clamping mechanism using, for example, a press-contact face plate are separately provided.

[Points to be solved by the invention] In the conventional example described above, the positioning accuracy is not necessarily sufficient due to the backlash between the bottle and the hole, and since the clamping is performed after positioning, the operation order is determined, and the positioning clamp takes time. There were problems such as the amount of water required.

An object of the present invention is to provide a new positioning clamp mechanism that eliminates the problems of the conventional example, improves positioning accuracy by integrating the positioning mechanism and the clamp mechanism, and shortens the time for positioning clamping. be.

[Means for solving the problem] The problem with the above-mentioned prior art is that the first member is provided with a recessed portion provided along two orthogonal lines, and the two straight lines facing the first member are also orthogonal. This problem is solved by comprising a second member having a convex portion provided along the ridge, and a driving means for driving the second member toward the first member.

[Example] The present invention will be described below with reference to Examples shown in the drawings. 1 and 2 show an embodiment of the positioning clamp mechanism according to the present invention, where l is a first member fixed to a moving pallet 2 of a transfer machine, for example, and is provided along two orthogonal straight lines. A total of two sets of triangular pyramid-shaped recesses 1a and lb are provided. Reference numeral 3 denotes a second member fixed to the tip of a sliding member 5 that is inserted into and guided through an angular guide path 4a formed in the center of a guide member 4 provided at a fixed portion of the transfer machine for the movable pallet 2. As shown in FIG. 2, two sets of triangular pyramid-shaped recesses L&
, 1b are provided with triangular pyramid-shaped protrusions 3a and 3b. 6 is a hydraulic cylinder equipped with a piston 6a connected to the rear end of the sliding member 5.

3 and 4 show other embodiments of the positioning clamp mechanism according to the present invention, in which a first member 11 and a second member 13 are provided in the same manner as in the embodiment shown in FIG. The first member 11 is provided with recesses 11a and 11b which form two grooves having a triangular cross section along two orthogonal lines, and the second member 13 is provided with two grooves that are formed along two orthogonal lines. Convex portions 13a and 13b having a triangular cross section are provided along the recesses 11a and llb having a triangular cross section.

In such a positioning clamp mechanism, a movable pallet 2 of a transfer machine is transported by a transport means (not shown) 1, and a first member l or 11 fixed to the movable pallet 2 is connected to a second member 3 or 13 provided on the fixed side. When the hydraulic cylinder 6 is stopped at a position approximately opposite to
The member 3 or 13 is pressed against the first member 1 or 11.

At this time, in the embodiment shown in FIG. 1, the triangular pyramid-shaped concave portions 1a, 1b provided on the first member 1 and the triangular pyramid-shaped convex portions 3a, 3b provided on the second member 3 are mutually connected. The first member 1 is accurately meshed, the first member 1 is corrected and positioned at the position of the second member 3 along two orthogonal straight lines, and the first member 1 is clamped by the second member 3 by the pressing force. Furthermore, in the embodiment shown in FIG.
The triangular convex portions 13a and 13b provided at 3 mesh accurately with each other, and the second member 13 similarly positions and clamps the first member 11.

[Effects of the Invention] As is clear from the above description, according to the positioning clamp mechanism of the present invention, there are two clamping mechanisms each having a concave portion and a convex portion formed along two straight lines perpendicular to each other. By pressing the parts together, the concave and convex parts mesh with each other without any gaps in the two orthogonal linear directions, realizing extremely high-precision positioning, and at the same time, the pressure force can be used to directly clamp the parts. becomes usable.
