Description
Technical field
The present invention relates to a kind of manipulator that the circular object automatic centering capturing can be placed.
Background technology
Full-fledged along with Robotics often requires robot to complete various grasping movement, and the object of crawl accurately need to be placed in the target location of regulation or the predetermined member of target device in industrial production and athletic competition.As needs are accurately aimed at circular object to be positioned on target substance or parts, the manipulator of existing crawl circular object, its structure is to comprise that postmedian is articulated with the left and right clamp arm on the liftable support of robot, the tail end of left clamp arm is articulated with on the lever of cylinder, step up on thick stick cylinder that arm is articulated with cylinder on the right side, it is hinged that the tail end of left and right clamp arm is also distinguished left and right synchronizing bar, and the other end of left and right synchronizing bar is articulated with in the longitudinal chute on liftable support.It is clamped and under the driving of cylinder, is clamped the circular object capturing by left and right, then robot motion is near target location, again by liftable support by the height alignment target location of object, then cylinder reverse drive, left and right clamp arm unclamps the circular object of crawl and is placed near target location.Because manipulator does not have the mechanism of auto-alignment placement location, need the situation of strict centering (as needs are placed on circular object on Precision Machining facility to placement location, carry out following process), conventionally need reprocessabilty repeatedly to operate control, repeatedly placing could be successful, wastes time and energy.Also the manipulator having arranges high-precision sensor by arrangement, to being installed, placement location carries out accurate synchronous detection and FEEDBACK CONTROL, also can realize auto-alignment, place operation, due to high-precision sensor costliness, perishable, production and the maintenance cost of manipulator are improved, also reduced the Stability and dependability of manipulator simultaneously.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of manipulator that the circular object automatic centering capturing can be placed, this kind of manipulator can be aimed at placement by the circular object capturing automatically automatically with target location, and it is simple in structure, to make with maintenance cost lowly, good stability, reliability are strong.
The present invention solves its technical problem, the technical scheme adopting is: a kind of manipulator that the circular object automatic centering capturing can be placed, comprise that postmedian is articulated with the left and right clamp arm on robot liftable support, the rear end of left clamp arm is articulated with on the cylinder bar of cylinder, the rear end of right clamp arm is articulated with on the cylinder barrel of cylinder, the rear end of left and right clamp arm is also hinged with left and right synchronizing bar respectively, and the other end of left and right synchronizing bar is articulated with in the longitudinal chute on liftable support; It is characterized in that:
Described left clamp arm is connected with left semicircle tapered sleeve by the left front support bar on right side and the left back support bar on right side, and the front end of left clamp arm is provided with left bearing one; Described right clamp arm is connected with right semi-circle tapered sleeve by the right anterior branch strut in its left side and the right back support bar in left side thereof, and the front end of right clamp arm is provided with right bearing one; Relative and large mouthful of the inner headed face of left semicircle tapered sleeve and right semi-circle tapered sleeve all down;
Described liftable support is fixed with vertical rod in the bottom at the center of left clamp arm hinged place and right clamp arm hinged place, and the bottom of vertical rod is connected with forward and wide-mouth clamp locating dowel adaptation.
The course of work of the present invention and principle are:
Under the effect of cylinder, left and right clamp arm closes up, liftable support and object are left front, the left bearing one on right anterior branch strut, the side that right bearing one pushes against circular object, the bottom support of circular object is on left front, left back, right front, right back support bar simultaneously, and circular object is clenched by manipulator.Robot moves towards target location, near robot moves to target location and near default locating dowel, liftable support rises until locate the bottom surface of tapered sleeve higher than the end face of locating dowel, robot is drawn close to locating dowel direction, wide-mouth clamp blocks locating dowel, realizes the preliminary centering of manipulator and locating dowel, and liftable support declines, location tapered sleeve packs into the top of locating dowel, the further accurate centering of the circular object that guiding captures and locating dowel.Cylinder cylinder bar shrinks, and left and right clamp arm unclamps, and circular object is that auto-alignment is accurately positioned over target location.As with holes in circular object center, wish is installed on circular object centre bore in locating dowel, realizes locating dowel automatic centering and inserts circular object centre bore.
Compared with prior art, the invention has the beneficial effects as follows:
The adaptive way of machinery that employing wide-mouth clamp and the tapered sleeve locating dowel default with target location are mated realizes the automatic centering of robot crawl circular object placement location and places.This Adaptive Mechanical centering method can realize centering accurately, reliably, efficiently; It is simple in structure simultaneously, and cost of manufacture is low, easy to maintenance, has also well ensured the reliability and stability of manipulator.
The front end of described left clamp arm is also connected with the left front support bar of large object left, the end of the large left front support bar of object is fixed with left bearing two, left clamp arm is fixed with the left back support bar of large object left at position, liftable support front, the end of left back support bar is also fixed with right baffle-plate upwards;
The head end of described right clamp arm is fixed with large object right anterior branch strut to the right, the end of large object right anterior branch strut is fixed with left bearing two, right clamp arm is fixed with the right back support bar of large object to the right at position, liftable support front, the end of right back support bar is also fixed with right baffle plate upwards.
Like this, in the time that needs capture larger object, the more large-area bracing frame that can be made up of left front, left back, right front, the right back large object support bar of large object, from the larger circular object of bottom supporting.Meanwhile, from the side large circular object is clamped by the baffle plate on the left bearing two on left front, right front large object support bar, right bearing two and left back, right back large object support bar.And the centering of the centering operation of itself and locating dowel and principle and above wisp is just the same.
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
