Abstract
The invention provides a tool fixture, which is suitable for clamping a cylindrical workpiece. The tool fixture comprises a load bearing platform and supporting legs for supporting the load bearing platform, wherein a cylinder and a piston are arranged below the load bearing platform; the free end of the piston is provided with a supporting plate; the cylindrical workpiece is arranged on the supporting plate; and the supporting plate serves as a reference positioning surface. The tool fixture comprises a positioning platform parallel to the surface of the load bearing platform; the positioning platform is provided with a through hole corresponding to the cylindrical workpiece; and the side surface corresponding to the cylindrical workpiece is provided with a convex rib. When a piston is under the action of the cylinder pressure to drive the supporting plate to move upwards to contact with the positioning platform, the cylindrical workpiece penetrates through the through hole on the positioning platform to expose out of the top surface. Meanwhile, the convex rib is clamped on the side surface of the cylindrical workpiece.
Description
Technical field
The present invention relates to a kind of frock clamp, especially be applicable to the frock clamp of applying on Digit Control Machine Tool.On technical field, belong to field of machining.
Background technology
In field of machining, often need to do deep processing to the workpiece of various shapes, therefore will adopt all kinds of frock clamps.For columniform workpiece, generally adopt the frock clamp of scroll chuck to clamp, each pawl that is scroll chuck clamps cylindrical work from the side, due to each pawl by screw-driving, therefore be difficult to guarantee that the dynamics applied on each pawl is consistent, will cause like this three direction unbalance stress of cylindrical work, in clamping process, the workpiece irregularities is upwards creeped (namely the bottom lower plane separates with positioning reference plane), cause in process the machine tool program depth dimensions uncontrollable, percent defective is higher, can't produce in batches.
Summary of the invention
The purpose of this invention is to provide and a kind ofly for cylindrical work, can guarantee firm clamping force, carry high-precision frock clamp.
The object of the invention is achieved through the following technical solutions: a kind of frock clamp, be applicable to cylindrical work is clamped, the supporting leg that comprises carrying platform and support bearing platform, the below that is positioned at carrying platform is provided with cylinder and piston, and the free end that is positioned at piston is provided with gripper shoe, described cylindrical work is placed on gripper shoe and take gripper shoe and is the origin reference location face, also comprise the locating platform parallel with carrying platform face face, on this locating platform, corresponding circle cylindricality workpiece is provided with perforation, the side of corresponding circle cylindricality workpiece is provided with fin, when piston subject cylinder pressure-acting drive gripper shoe is moved upward to the contact locating platform, described cylindrical work passes the perforation on locating platform, expose end face, simultaneously, fin is clamped in the side of cylindrical work.
Preferably, between described carrying platform and locating platform, also be provided with lead, on gripper shoe, corresponding lead is provided with pilot hole.
Preferably, the bottom surface of corresponding circle cylindricality workpiece, gripper shoe is provided with circular groove, and the bottom surface of its diameter and cylindrical work is suitable.
Preferably, by sidewall, be fixedly connected with between described carrying platform and locating platform, the mode of connection is that screw connects.
Beneficial effect of the present invention is mainly reflected in: owing to having adopted pneumatic pinch here, can guarantee each clamping force in the same size, and the clamping force size is adjustable arbitrarily, workpiece bottom lower plane is clamping area, eliminated workpiece bottom lower plane and positioning reference plane separation problem in clamping process, guaranteed that positioning datum is consistent with machining benchmark, also guaranteed that the machine tool program depth dimensions is certain value, guarantee product quality, realized batch production.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Fig. 1 is the schematic diagram of frock clamp of the present invention.
Fig. 2 is the side view of this frock clamp.
Fig. 3 is the top view of this frock clamp.
The specific embodiment
Refer to Fig. 1 to Fig. 3, the invention provides a kind of frock clamp, be applicable to specific cylindrical work 1 is clamped, and then do deep processing by Digit Control Machine Tool.This frock clamp comprises the supporting leg 4 of carrying platform 2, locating platform 3 and support bearing platform 2, and 3 faces of carrying platform 2 and locating platform are parallel, by sidewall 5, is fixedly connected with between the two, and the mode of connection is that screw connects.
Be positioned at the below of carrying platform 2, be provided with cylinder 6 and piston 7, and the free end of piston 7 is provided with the gripper shoe 8 of support cylinder shape workpiece 1, when cylinder 6 inflation, the movement that the stressed generation of piston 7 makes progress, and then drive gripper shoe 8 and move up in the lump, and gradually near locating platform 3.
Owing to having adopted pneumatic pinch here, can guarantee each clamping force in the same size, and the clamping force size is adjustable arbitrarily, workpiece 1 bottom lower plane is clamping area, eliminated workpiece 1 bottom lower plane and positioning reference plane separation problem in clamping process, guaranteed that positioning datum is consistent with machining benchmark, also guaranteed that the machine tool program depth dimensions is certain value, guarantee product quality, realized batch production.
In order to prevent that gripper shoe 8 from producing radial displacement upper in moving past journey, between support platform 2 and locating platform 3, also be fixedly connected with lead 9, the corresponding pilot hole 81 that is provided with on gripper shoe 8, it is socketed on lead 9, thereby can guarantee that gripper shoe 8 moves up and down along lead 9 all the time.In addition, for firm cylindrical work 1, corresponding its columniform bottom surface, on gripper shoe 8, also be provided with circular groove 82, the bottom surface of the diameter of this groove 82 and cylindrical work 1 is suitable, and then the bottom surface of cylindrical work 1 is contained in groove 82 fully, further improves positioning precision.
On locating platform 3, corresponding circle cylindricality workpiece 1 is provided with perforation 31, makes cylindrical work 1 can pass perforation 31, exposes its end face to prepare to carry out deep processing.In order to keep adding the stability in man-hour, the perforation 31 on this locating platform 3 also is formed with two fins 32, from the left and right sides, surrounds the side of cylindrical work 1.
In use, at first the operator is placed on cylindrical work 1 on gripper shoe 8, needs corresponding its groove 82 to place, then, start cylinder 6, piston 7 will drive gripper shoe 8 and move up along lead 9, and gradually near locating platform 3, finally, when gripper shoe 8 arrived summit, namely gripper shoe 8 was with after locating platform 3 contacts, cylindrical work 1 will pass perforation 31, expose its end face, simultaneously, two fins 32 prevent its rotation from both sides clamping work pieces 1.Now, the user just can continue the operating numerical control lathe cylindrical work 1 is carried out to deep processing.
