A kind of irregularly shaped object clamping tooling
The utility model relates to a kind of clamping tooling, is specifically related to a kind of clamping tooling for irregularly shaped object.
Enterprise is a lot of for the processing of irregularly shaped object at present, for example, the processing of strange shape cast member, processing of the building stones of exploitation etc., general processing method is first to carry out roughing at present, part using this without processing processes as coarse positioning clamping benchmark, and then carries out the processing of fine positioning clamping benchmark, after smart benchmark machines, clamping carries out the processing of other operations again, so not only technique is loaded down with trivial details, and precision be difficult to guarantee, waste time and energy.So that sapphire crystal is carried out to clamping as example: sapphire embryos is grown in growth furnace, its profile is irregular, so sapphire embryos must be measured crystallization direction to embryos before tangent plane processing, then carries out the processing of the locating surface (reference planes) of embryos according to the direction of measuring.Common method to the processing of embryos locating surface is that embryos is placed on direction finder, carry out embryos to measure after crystallization direction, draw the cutting planes line that will cut with oil pen, then crystal is transferred on sawing machine, the line of cut drawing according to orientation positions clamping, due to embryos Profile Growth out there is no certain rule, so positioning and clamping has been brought to very large difficulty, enterprise is for the clamping processing of this irregularly shaped object at present, all to adopt artificial location, the mode of hand-operated clamping, and while clamping, be filled in the surface of irregular workpiece with various materials, not only waste time and energy, and after clamping, location is incorrect, all that has been achieved is spoiled, can only do again from the beginning, again clamping, existing installation way has limited the automated production of enterprise greatly.
Summary of the invention
The problem existing for prior art, the utility model provides a kind of clamping tooling for irregularly shaped object.
The problem existing for solving prior art, the technical scheme that the utility model is taked is: a kind of irregularly shaped object clamping tooling, comprise pedestal and be arranged on the fixture on pedestal, it is characterized in that: described fixture comprises at least two claws, in claw, being provided with the utricule of import and export.Top off in utricule in use, the used time can not emit gas, adopts utricule directly to contact irregularity surface, has strengthened like this and the contact area of caught object, is more conducive to protection and grip objects.
At least one claw is connected with the fixture open-and-close mechanism that is fixed on pedestal.This connected mode is integrally formed fixture open-and-close mechanism and device pedestal.
At least one claw coordinates with the guide rail being arranged on pedestal, and described fixture open-and-close mechanism is cylinder or the oil cylinder being fixed on pedestal, the piston rod of cylinder or oil cylinder and guide rail parallel, and be connected with the claw being arranged on guide rail.This structure is convenient to piston rod and is driven the claw on guide rail to clamp object.
For the caught object that adequately protects is not damaged, on the relative end face of each claw, be provided with flexible pad.Described flexible pad is inlayed with the mode of pasting and is fixed on the end face that each claw is relative by T-shaped groove.
On guide rail between each claw, be provided with auxiliary table, described auxiliary table is arranged on guide rail top by slide block, thereby has guaranteed that auxiliary table can move freely along guide rail.
On pedestal, be provided with two relative claws, one of them is the stationary jaw being fixed on pedestal, and another is the movable jaw on pedestal by guide rails assembling, is fixed with cylinder or oil cylinder on pedestal, the piston rod of cylinder or oil cylinder and guide rail parallel, and its front end is connected with movable jaw.
The utility model adopts hydraulic pressure as power drive movable jaw, movable jaw promotes irregularly shaped object and moves to stationary jaw direction, irregularly shaped object and auxiliary table produce stiction, thereby drive auxiliary table along guide rail movement, location can not be subject to clamping force and change object clamping because of object in object clamping process like this time, the accuracy of location when auxiliary table is more conducive to guarantee to clamp along guide rail freely-movable design.Utilize elastomeric material directly to contact with irregularly shaped object, strengthened the contact area of fixture and caught object, improved the stability that clamps quality, the damage to caught object while having avoided rigidity contact gripping.This device clamping is simple, easy to operate, time saving and energy saving, is beneficial to specialized production.

The specific embodiment
A kind of irregularly shaped object clamping tooling, comprise pedestal 1 and be arranged on the fixture on pedestal, described fixture comprises two relative claws, one for being fixed on the stationary jaw 6 on pedestal 1, another is for to be arranged on the movable jaw 7 on pedestal 1 by guide rail 2, is provided with on the end face that the utricule 8 of import and export and each claw are relative and is provided with flexible pad 9 in each claw.Stationary jaw 6 is connected with the fixture open-and-close mechanism 3 that is fixed on pedestal 1, and described fixture open-and-close mechanism 3 is cylinder or oil cylinder, and the piston rod 4 of cylinder or oil cylinder is parallel with guide rail 2, and its front end is connected with movable jaw 7.On guide rail 2 between two claws, be provided with auxiliary table 5.
Irregularly shaped object is lifted on the auxiliary table 5 of this device, press the clamping button of cylinder or oil cylinder, movable jaw clamps irregularly shaped object under the drive of piston rod 4, while auxiliary table 5 is followed caught object and is slided to stationary jaw 6 along guide rail 2, after clamping completes, just can carry out ensuing processing.
