SUMMARY

[0003] The object of the present invention is to solve the problem of the above-described mechanism of the loading and unloading robot, provide a simple, compact, easy to install, inexpensive to manufacture a new type of vertical manipulator mechanism. To this end, the present invention adopts the following technical scheme:

[0004] A novel vertical manipulator, characterized in that: two vertical cylinders and the cylinders are fixed opening and closing the left and right sides of a small column, the slider is connected to the vertical drive cylinder, symmetrical distribution of two sets of mechanical jaws connected through a guide post on the bearing outer ring gear, the gear bearing inner ring is fixed on a small column, fixed to the pinion rotation rail post. The mechanical jaw comprising: a wedge, guide bearings, slide symmetrically distributed around the jaws, die springs and spring guide rod.

[0005] As a further improvement of the above scheme and complement, the present invention further includes the following additional features:

Said upper and lower cylinder [0006] and the open-close cylinder without a mechanical jaw fixed connection.

After [0007] the mold jaws of the mechanical spring preload spring mounted on the slider and the guide rods intermediate.

[0008] clamping jaws guide the mechanical bearing is a deep groove ball bearings.

[0009] clamping jaws of the machine to the top of the slider wedge contact surface is triangular.

[0010] Using the present invention can achieve the following advantageous effects: upper and lower cylinders and the opening and closing cylinder only symmetrical initial position and the robot cooperate to achieve the clamping part in a loading position, while the lower feed position to achieve the installation part, and not accompanied by mechanical jaws for loading and unloading cycle of rotary motion; this structure reduces the weight of the mechanical jaw loading and unloading, reduce the failure rate; the present invention the mechanical opening and closing of the jaws simple structure, reliable operation, easy to manufacture and ,low cost.

BRIEF DESCRIPTION OF:

[0011] FIG 1, FIG 2 is a partial cross-sectional view of the present invention. FIG 3 is a front view of mechanical jaws, FIG. 4 is a sectional view of a mechanical gripper.

Detailed ways

DRAWINGS The invention is described in detail specific embodiments [0012] below in conjunction.

[0013] FIG. 1 ~ FIG. 4 of the present invention comprises: two sets of upper and lower cylinder 2 and the cylinder 3 is fixed to the opening and closing small pillar left and right sides, respectively, of the I, the slider 4 is connected to the cylinder 2 in the vertical, bilaterally symmetric distribution two sets of mechanical jaws 6 is connected to the bearing outer ring gear 7 through a guide post 10, bearing inner ring gear fixed to the pinion 8 column, 5 is fixed in the rotation track on a small column. The mechanical jaw 6 comprises: wedge block 12, the guide bearing 16, the slider 13 symmetrically distributed around the jaws 11, the mold spring 14 and the spring guide rod 15.

[0014] When using the present invention, because the left and right sides of the two jaws 6 mechanical operation identical manner, two sets of mechanical jaws 6 while gripping the workpiece, a workpiece is placed is also simultaneously, so as to be located only a small column I the right 6 machine side jaw operation will be described as an example; FIG. 1 ~ 4 are shown in an initial position, [4 slider shaped opening on a plane contour and a plane of rotation of the lower rail 5, the guide bearing 16 in the slider card 4 [-shaped opening, the mechanical jaws 6 in the clamped state. In operation, the opening and closing drive cylinder piston rod 3 is moved downward onto the cylindrical surface 12 in contact with the wedge, and the wedge continues to move downwardly forcing the slider 13 against the block 12 the elastic force of the die springs 14 to separate the left and right, so that the slide is connected block 13 on the right and left jaw 11 while being spaced apart, i.e., mechanical jaws 6 in the expanded state; in this case driving the slider 4 is moved downward by the vertical cylinder guide bearing 16 and driven by the robot gripper 6 is moved down to the work position, opening and closing cylinder piston rod 3 is retracted, the spring 14 drives the slide mold 13 is moved and driven by the intermediate jaw 11 is closed, the vertical driving cylinder 4 to drive the mechanical slider jaws 6 raised to the initial position, thereby completing the operation of gripping the workpiece. Driving means 9 drives the bearing outer ring gear 8 is rotated and driven by the mechanical jaw 6 rotates around the small column I, guide bearing 16 out of the slider 4 [roll-shaped opening and the plane of rotation of the rail 5, until the bearing outer ring gear 8 rotated 180 degrees, the left and right sides of the mechanical jaw 6 complete transposition operation. On the right of the mechanical jaw workpiece 6, the upper and lower jaw cylinder 2 driven machinery 6 is moved down to the designated position, the opening and closing operation of the cylinder 3 driven jaws 11 open, mechanically driven down the cylinder 2 after opening the jaws 6 Reset reset cylinder 3 together, thereby completing the part is placed in the specified location operation.

[0015] Finally is noted that, the above embodiments are merely illustrative of the technical solution of the present invention and not limitation, although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will appreciate, this may technical solution invention modifications or equivalent replacements without departing from the spirit and scope of the technical solutions of the present invention, which should fall within the claimed scope of the claimed invention.
