DESCRIPTION:
BRIEF SUMMARY
This Patent of Invention refers to a mechanical carrier, or more particularly, to a part transference or transportation device, mechanically jointed, upon driving of pneumatic pistons, hand or automatically control by means of a control panel, in a way that the grasping system can be displaced pursuant to vertical and horizontal way, which are driven independently or jointly, so as to permit the removal of a part from one place to another. Therefore, this mechanical carrier is presented as an automatic and/or hand controlled device, to used in mass or normal production, in which various applications are feasible, mainly in metalworking shop, for extraction or automatic feed of parts for the interior of metal stamped parts in any kind of pressing machines, as well as for transferences of parts from one machine to another, performing different operations. As last, this mechanical carrier can be used at any production site, either for mass or normal production, wherein an equipment to perform the moving of parts from one place to another, mainly between machines, is needed.
In order to provide a better understanding of this patent of Invention, references will be made to the attached drawings, wherein
FIG. 1 is a front view;
FIG. 2 is a side view, under partial cut; finally
FIG. 3 is a schematic side view, ilustrating the functioning of this mechanical carrier.
This Patent of Invention refers to a mechanical carrier (see FIGS. 1 and 2) comprising a chassis/base (1), in vertical position, which provides the fastening of the set to the machine or equipment in which it shall be used, said chassis presenting side guides (2), wherein a movable internal body (3), is moved, driven by a pneumatic cylinder (4), the body of which is fastened in parallel to the internal face of the chassis/base (1); in the upper part of the said movable body (3) is located a first linkage means (5) comprising a pair of cross arms, parallel to each other, one of them in upper position (6), and the other in a lower one (7), both with one of the ends jointly mounted to the movable body (3), while the opposite ends of the same are also jointly fixed to a triangular part (8), the upper vertex has also fixed thereto the end of a chain (9), which, in turn, is developed upwards, thus fitting a gear (10) mounted at the upper part of the movable body (3), being afterwards developed downward, so as to have an end linked to the piston of a cylinder (11), duly fixed to the movable body (3).
In one of the lower vertex of the triangular part (8), or, more precisely, in its right angle vertex, there is jointly fixed, together with a corresponding end of the lower arm (7), the upper end of a cylindrical stem (12) which develops downward and within a tubular jacket (13), the positioning of which is determined by an upper support (14) and a lower support (15), the upper support (14) having an end welded to the corresponding end of the jacket (13), while its other end is jointly fixed to the free vertex of the triangular part (8), while the lower support (15) is geometrically fixed in a way that its free end can be jointly interconnected to the lower end of the stem (12), through a horizontal element (16), and also to have the jointed ends of said supports (14) and (15) remaining on the center line (A) paralel to the longitudinal center line (B) of the tubular jacket (13), said paralel condition being maintained under any circumstances.
A bearing (17) leaves the medium part of the tubular jacket (13), in the free end of which there is a cross axle (18), which is orthogonally centered on line (A), so permiting that, at the free ends of said axle, the upper ends of the side arms (19) be jointly coupled, the lower ends being fixed to axles, revolvingly mounted at the side parts (20) of the movable body (3), wherein one of said axles is extended outward enough to receive a last radial arm (21), at the free end of which it is coupled the terminal of a piston (22) of a pneumatic piston (23), conveniently mounted at the outer part of the movable chassis (3).
