Description of the drawings
Fig. 1 is the explosive view of the utility model embodiment；
Digital representation in figure：
1 pedestal, 11 risers, 12 counterbore slots, 13 first guide pillar holes, 14 pin holes, 2 left intermediate plates, 21 right clamping pieces, 22 clamping faces,
23 second guide pillar holes, 24 through-holes, 3 guide posts, 31 baffle rings, 32 positioning pins, 33 catching grooves, 4 compressed springs.
Specific implementation mode
Clear, complete description will be carried out to the technical scheme in the embodiment of the utility model below in conjunction with the accompanying drawings, it is clear that
The described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.
Embodiment：
Shown in referring to Fig.1, the present embodiment is the mechanical grip with positioning buffer unit, including symmetrically arranged fixed seat,
Intermediate plate, fixation kit and bolster.
Fixed seat includes pedestal 1, is set to 1 monosymmetric riser 11 of pedestal.Rectangular counterbore slot is offered in pedestal 1
12 so that fixed seat 1 can be easily mounted in manipulator ontology (not shown).It is respectively symmetrically horizontal right in the riser 11 of both sides
Position offers one group of first guide pillar hole 13.Pin hole 14 is further opened in the riser 11 of front end, pin hole 14 is located at the first guide pillar hole 13
Lower section.
Intermediate plate includes being respectively embedded into the left intermediate plate 2 being installed in symmetrical fixed seat and right clamping piece 21, left intermediate plate 2 and right clamping piece
With respect to the clamping face 22 equipped with arc, the matching corresponding with axial plane workpiece to be held of clamping face 22 in 21.The bottom pair of intermediate plate
Claim to be equipped with the second guide pillar hole 23, the bottom of intermediate plate is additionally provided with through-hole 24, and the lower section of the second guide pillar hole 23 is equipped with through-hole 24.Through-hole 24
Contraposition corresponding with pin hole 14, the contraposition corresponding with the second guide pillar hole 23 of the first guide pillar hole 13.
Fixation kit includes guide post 3, baffle ring 31 and positioning pin 32.The both ends of guide post 3 are respectively equipped with catching groove 33, and guide post 3 passes through
The first guide pillar hole 13 and the second guide pillar hole 23 are worn, baffle ring 31 is installed in catching groove 33.
Bolster is compressed spring 4, and bolster is placed in through-hole 24, and positioning pin 32 is plugged to bolster through pin hole 14
It is interior, convenient for positioning compressed spring 4.Baffle ring 31 effectively prevent guide post 3 to be sliding out fixed seat.
When using the present embodiment, arm-and-hand system (not shown) controls clamping jaw clamping workpiece, is put into jig
Designated position, along the direction that workpiece is put into, manipulator moves forward a certain distance；At this point, due to jig itself
Anchor point contact workpiece positioning surface, will produce the active force with the mechanical grip reversing of motion, mechanical grip clamping workpiece
It can take advantage of a situation after stress and squeeze compressed spring to negative direction, compressed spring generates buffering, same to mitigate mechanical grip stress itself
When so that workpiece is accurately positioned；After lathe effect clamps workpiece, manipulator unclamps intermediate plate, and compressed spring 4 loses cushion effect and resets,
Complete clamping action.
The present embodiment using mechanical grip kicking motion offset because jig positioning or workpiece size error generate
Position error；Suitable for axial workpiece, disk-like accessory or special-shaped part, increase the scope of application；Mechanical grip has cushioning effect,
Intermediate plate is protected, is prolonged the service life while accurate work piece positioning.
Above-described is only some embodiments of the utility model.For those of ordinary skill in the art,
Without departing from the concept of the present invention, various modifications and improvements can be made, these belong to this practicality
Novel protection domain.
