Abstract
The invention discloses a strip hole type workpiece grabbing mechanism. The strip hole type workpiece grabbing mechanism comprises a force applying rod, two clamping jaws, a spring and two control rods, wherein the two clamping jaws are arranged oppositely; each control rod is hinged to the inner side of the clamping end of the corresponding clamping jaw; a strip-shaped hole is formed in one end of each control rod along the length direction; a guide head is arranged at one end of the force applying rod and is slidably connected to the interior of the two strip-shaped holes; a supporting rod is connected to the other end of each control rod; a polishing head is arranged between the two supporting rods, is connected with the supporting rods through the spring and corresponds to an edge of a to-be-grabbed workpiece. The force applying rod can clamp the workpiece by virtue of the strip-shaped holes of the control rods and can drive the supporting rods to sleeve the polishing head and the spring. When the workpiece grabbing mechanism starts to move, the polishing head can be driven to move on the spring back and forth by virtue of an accelerated speed during transportation, and the edge of the workpiece is polished. The strip hole type workpiece grabbing mechanism can be used for machining the workpiece in an auxiliary way while grabbing the workpiece, and the transportation process of the workpiece is better utilized.
Description
Technical field
The invention belongs to the technical field of clamping device.
Background technology
Workpiece grabbing mechanism is used for piece-holder, and is transported to suitable position.Workpiece grabbing mechanism, when crawl and transmitting workpiece, is not average rate, even sometimes also needs to loiter.
When we capture workpiece be blank or semi-finished product time, next step operation of crawl normally to blank and half-finished processing, such as deburring, chamfered edge, angle rounding etc.Current operation is just processed blank and semi-finished product after transmitting workpiece, when grasping mechanism transmitting workpiece, can not process or secondary process workpiece, not utilize this operation of transmitting workpiece preferably.
Summary of the invention
The invention provides a kind of bar cellular type workpiece grabbing mechanism, can not process workpiece or the problem of secondary process to solve existing workpiece grabbing.
In order to solve the problems of the technologies described above, the invention provides following technical scheme: a kind of bar cellular type workpiece grabbing mechanism, comprise force application rod, two jaws be oppositely arranged, spring and two control levers, two control levers are hinged on the inner side of jaw bare terminal end respectively, two control lever one end all have bar hole along its length, one end of force application rod is provided with guide head, guide head is slidably connected in two bar holes, the other end of two control levers is connected with pole, grinding head is provided with between two poles, grinding head is connected by spring with pole, grinding head correspondence treats the edges and corners of grabbing workpiece.
Principle of the present invention is: promote force application rod, and force application rod drives control lever to rotate, and when the bar hole of control lever is away from workpiece, control lever can clamp, thus drives two jaw clampings.Simultaneously, control lever can towards workpiece motion s away from one end of bar hole, the pole be connected with control lever also can near workpiece, workpiece surrounds by grinding head and spring, because of workpiece grabbing mechanism motion be not uniform motion, grinding head postbacks the movement of returning from birth, thus polishes to the edges and corners of workpiece.
Compared with prior art, the invention has the advantages that: force application rod is by the bar hole of control lever to realize the clamping of workpiece, and force application rod can also drive pole grinding head and spring to be inserted in simultaneously.When workpiece grabbing mechanism setting in motion, can grinding head be driven by acceleration during transport to move around on spring, be polished in the edges and corners of workpiece.The present invention to workpiece secondary process, reasonably can make use of this characteristic that workpiece is non-uniform velocity when transporting, utilizing this operation of transmitting workpiece preferably while grabbing workpiece.
Further, the shape of grinding head is cylinder, makes the contact of grinding head and workpiece be linear contact lay, only contacts with needing the corner angle of polishing, and tries not, with the surface contact of workpiece, to prevent the surface mill flower that grinding head will process.
Further, the end of bar hole can with guide head clamping, making guide head when being positioned at bar hole end, on condition that an external force is not applied, being in stable state.
Further, guide head is hinged on one end of force application rod, and guide head can roll in bar hole, reduces the frictional force between guide head and bar hole inwall.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, technical solution of the present invention is further illustrated:
Fig. 1 is the structural representation of bar cellular type workpiece grabbing mechanism embodiment of the present invention.
Detailed description of the invention
Reference numeral in Figure of description comprises: force application rod 1, jaw 2, spring 3, control lever 4, bar hole 5, guide head 6, grinding head 7, pole 8, workpiece 9.
As shown in Figure 1, the bar cellular type workpiece grabbing mechanism in the present embodiment, needs the workpiece 9 captured to be cuboid, comprises jaw 2, spring 3 and two control levers 4 that force application rod 1, two is oppositely arranged.Two control levers 4 are hinged on the inner side of jaw 2 bare terminal end respectively, and two control lever 4 upper ends respectively have a bar hole 5 along its length.The lower end of force application rod 1 is hinged with guide head 6, and the shape of grinding head 7 is cylinder, and guide head 6 is slidably connected in two bar holes 5, the upper end of bar hole 5 can with guide head 6 clamping.The lower end of two control levers 4 is connected with to be provided with between four grinding heads 7, two grinding head 7 between pole 8, two pole 8 and is connected by spring 3, also connected by spring 3 between grinding head 7 and pole 8, the side of the corresponding cuboid of grinding head 7 is stupefied.The deformation quantity of spring 3 should be not more than the diameter of chamfering.
Force application rod 1 is pushed away downwards, the guide head 6 of force application rod 1 can move downward along bar hole 5, the upper end of drived control bar 4 moves downward, the lower end of control lever 4 moves upward, control lever 4 can be in the state of expansion, and control lever 4 can drive jaw 2 to launch, and workpiece 9 can be released, the pole 8 being positioned at control lever 4 lower end also can move upward, and grinding head 7 can depart from workpiece 9.
By force application rod 1 to pull-up, the guide head 6 of force application rod 1 can move upward along bar hole 5, the upper end of drived control bar 4 moves upward, the lower end of control lever 4 moves downward, and control lever 4 can be in the state of gathering, and control lever 4 can drive jaw 2 to draw in, workpiece 9 can be clamped gradually, the pole 8 being positioned at control lever 4 lower end also can move downward, and grinding head 7 and spring 3 can entangle whole for the side of workpiece 9, and grinding head 7 contacts with the side of workpiece 9 is stupefied.When guide head 6 slides into the top of bar hole 5, workpiece 9 is in clamped state, and guide head 6 is connected in bar hole 5, and when not applying external force, workpiece 9 can be in clamped state.When the whole unlatching of mechanism is mobile, because the speed of its transport is non-uniform velocity, there is acceleration, the mill of grinding head 7 meeting near side is stupefied, because there is spring 3, can store energy, grinding head 7 can realize grinding repeatedly near side is stupefied meanwhile.The deformation quantity of spring 3 should be not more than the diameter of chamfering, and the scope of wearing and tearing can not exceed requirement.
For a person skilled in the art, under the prerequisite not departing from structure of the present invention, can also make some distortion and improvement, these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
