Description
Technical field
The utility model relates to the adjustable gripping mechanism of a kind of gripping angle, belongs to thin sheet metal component clamping device field.
Background technology
Existing clamp is that it moves axially by single Driven by Hydraulic Cylinder.But existing clamp can only move radially, and clamp is in moving process, and the direction of jaw cannot change, and this structure causes the skinning surface that existing clamp cannot realize thin sheet metal component.So-called skinning surface is exactly stretched by the outline of thin sheet metal component along model, draws after stretching end, the outline of thin sheet metal component and the outline of model basically identical.
Summary of the invention
The gripping mechanism that the utility model provides a kind of gripping angle adjustable for overcoming the deficiencies in the prior art, solving in drawing process cannot the problem of skinning surface.
For solving the problem, the utility model adopts following technical scheme: the gripping mechanism that a kind of gripping angle is adjustable, comprise pedestal and be arranged on the grip module on described pedestal, described gripping mechanism also comprises angular adjustment assembly, described angular adjustment assembly comprises the first adjustment cylinder and second and regulates cylinder, described first regulate the piston rod on cylinder and described pedestal hinged, its hinged place forms the first axle center, described second regulate the piston rod on cylinder and described pedestal hinged, its hinged place forms the second axle center, described first regulates cylinder to promote described pedestal rotates around described second axle center, described second regulates cylinder to promote described pedestal rotates around described first axle center.
In the utility model first regulates cylinder by moving axially piston rod, pedestal to be rotated around the second axle center, or second regulates cylinder by moving axially piston rod, pedestal to be rotated around the second axle center.This structure effectively increases the motion track of gripping mechanism, meanwhile, also realizes the object of grip module movement in a plurality of directions, so that grip module skinning surface.
Further, described pedestal side be provided with the first support and with described first support not at the second support of same level height, described first regulates cylinder and described first support hinged, described second adjustment cylinder and described second support hinged.Because the first support and the second support be not at same level height, this just means, first regulates cylinder and second to regulate the length of cylinder inconsistent, and this can save the maintenance cost of angular adjustment assembly.
Further, described pedestal rotates 60 °-120 ° around described first axle center or described second axle center.Pedestal is in the first axle center rotary course, and second regulates the piston rod on cylinder to move axially, for pedestal carries the active force of over-rotation.After pedestal rotates to an angle, second regulates the thrust of cylinder to pedestal to be less than or equal to the gravity of pedestal self, therefore, second regulates the piston rod on cylinder cannot continue to move axially, thus promote pedestal continuation rotation, so pedestal is arranged between 60 °-120 ° around the angle that the first axle center rotates, avoid the generation of above-mentioned situation.Pedestal is around the second axle center rotary course, consistent with the principle that pedestal rotates around the first axle center, and therefore, pedestal is arranged on 60 °-120 ° around the angle that the second axle center rotates.
Further, described pedestal is provided with rotary components, described rotary components comprises spin and locating piece, described rotary components is fastened on described pedestal by described locating piece, described spin is arranged in described locating piece, be provided with the rotating shaft running through described spin in described spin, described roller end inserts described piston rod.When frictional resistance between spin and rotating shaft is excessive, spin can rotate in locating piece, when this structure can effectively avoid the dimensional accuracy due to rotating shaft or pedestal to cause local interference fit not, thin sheet metal component is by grip module drawing crack, or inconsistent with the outline of model after thin sheet metal component stretch forming.
Further, described grip module comprises clamp and working cylinder, and described clamp comprises at least two pincers teeth, and be provided with jaw between adjacent described pincers tooth, the piston rod on described working cylinder drives described clamp to move axially.
Further, described grip module also comprises holder, described grip module is arranged on described pedestal by described holder, described holder is provided with mounting groove, described clamp is arranged in described mounting groove, the sidewall of described mounting groove is provided with the guide pad of corresponding described pincers tooth, and described pincers tooth is close to described guide pad and is slided and can open or close described jaw.Pincers tooth is clamped in thin sheet metal component process, if the clamping force between pincers tooth and thin sheet metal component is too small, in adjusting part moving process, pincers tooth laminating guide pad also moves towards jaw direction, thus the interaction force between pincers tooth and thin sheet metal component increases, after interaction force between pincers tooth and thin sheet metal component increases, frictional force between pincers tooth and thin sheet metal component also increases thereupon, and this can be avoided causing adjusting part mutually to stagger in moving process because frictional force is not enough between pincers tooth and thin sheet metal component.If, if after the frictional force between pincers tooth and thin sheet metal component exceedes the frictional force between guide pad and pincers tooth, even if adjusting part continues mobile, also can not there is mutual slip in pincers tooth and guide pad, this can be avoided causing thin sheet metal component by drawing crack because clamping force is excessive between different pincers teeth.
Further, described first regulates cylinder, described second to regulate cylinder and described working cylinder to be oil cylinder, or described first regulates cylinder, described second to regulate cylinder and described working cylinder to be cylinder.
