Abstract

The invention relates to a clamping tool for an irregular object. The clamping tool comprises a base and a clamp installed on the base. The clamp comprises at least two clamping claws, wherein openings of the clamping claws are opposite. Each clamping claw comprises an outer claw body connected with the base and an inner claw body arranged in the outer claw body, wherein the inner claw body is connected with a transmission rod penetrating out of the outer claw body, and the inner claw body is provided with a capsule body with an inlet and outlet. Flexible pads are arranged on opposite upper and lower plate faces of each outer claw body. At least one outer claw body is connected with a clamp opening and closing mechanism fixed to the base. According to the clamping tool, the irregular object is clamped through the two-step mode of pre-clamping through the clamp opening and closing mechanism and main clamping through the transmission rods, hydraulic pressure is adopted as power to drive the movable clamping claws in the pre-clamping step so that the irregular object can drive an auxiliary worktable to move, and accordingly positioning accuracy can be guaranteed more easily. Because an elastic material is adopted to make direct contact with the irregular object, damage to the clamped object is better prevented, and the stability of clamping quality is improved. The clamping tool is simple in clamping, convenient to operate, capable of saving time and labor and beneficial for specialized production.

Description

Irregularly shaped object clamping tooling

Technical field

The present invention relates to a kind of clamping tooling, be specifically related to a kind of clamping tooling for irregularly shaped object.

Background technology

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 is difficult to guarantee, wastes time and energy.Take 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, with oil pen, draw the cutting planes line that will cut, 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, with various materials, be filled in the surface of irregular workpiece, 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 invention provides a kind of clamping tooling for irregularly shaped object.

The problem existing for solving prior art, the technical scheme that the present invention takes is: irregularly shaped object clamping tooling, comprise pedestal and be arranged on the fixture on pedestal, described fixture comprises at least two claws that opening is relative, each claw comprises the outer pawl being connected with pedestal and is arranged on the interior pawl in outer pawl, interior pawl is connected with the drive link that passes outer pawl, interior pawl and outer pawl are the casing of medial surface opening, its upper and lower plates is towards interior outstanding, front and back sides is inclined-plane with middle part with the end face being connected of upper and lower plates, before and after interior pawl, the inclined-plane of side plate is parallel with the inclined-plane of side plate before and after outer pawl, in interior pawl, be provided with the utricule of import and export, the relative upper and lower plates face of each outer pawl is provided with flexible pad, at least one outer pawl is connected with the fixture open-and-close mechanism being fixed on pedestal.In use utricule is carried out to punching press, the used time can not laid down pressure, adopts utricule directly to contact irregularity surface, has strengthened like this contact area with caught object, is more conducive to protection and grip objects.The upper and lower plates of interior pawl and outer pawl, towards interior outstanding, is more conducive to the clamping of irregularly shaped object, is especially beneficial to control spherical or cylindrical object and make it be difficult for skidding off fixture, and it is firm to clamp.Before and after interior pawl, the inclined-plane of side plate is parallel with the inclined-plane of side plate before and after outer pawl, consistent to the application of force direction of caught object, clamps firmly.This connected mode of fixture open-and-close mechanism is integrally formed fixture open-and-close mechanism and device pedestal.

For flexible pad is firmly secured on outer pawl upper and lower plates face, on outer pawl upper and lower plates face, with T-slot, a side of flexible pad is with the T shape projection adapting, and T shape projection is inserted in the T-slot on outer pawl upper and lower plates face.

Flexible pad tilts to extend in claw inner chamber, and consistent with the inclined end face direction of connected claw leading flank.

At least one outer pawl coordinates with the guide rail arranging 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 outer pawl being arranged on guide rail.This structure is convenient to piston rod and is driven the outer pawl on guide rail to clamp in advance object.

The drive link that is connected with interior pawl and passes outer pawl is screw mandrel, and its outer end is connected with handle or handwheel.Manual manipulation handle or handwheel just can accurately clamp object.

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, another is movable jaw, the outer pawl of movable jaw by guide rails assembling on pedestal, on pedestal, be fixed with cylinder or oil cylinder, the piston rod of cylinder or oil cylinder and guide rail parallel, and its front end is connected with the outer pawl of movable jaw.When utilizing open-and-close mechanism to clamp in advance, movable jaw moves to stationary jaw along guide rail under the drive of piston rod, and object is clamped in advance.

The present invention adopts the pre-clamping of fixture open-and-close mechanism and the tight two step modes of drive link main folder to clamp irregularly shaped object, and pre-clamping 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 in the time of can not being subject to clamping force and changing object clamping because of object in object clamping process like this, 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.
