Abstract
The utility model discloses an automatic centering fixture, which relates to the technical field of cutting equipment fixtures. The automatic centering fixture comprises a left V-shaped fixture block (1), a right V-shaped fixture block (2), a gear (3), racks (4), a push rod (5) and a hydraulic cylinder (6), wherein one rack (4) of which teeth are downward is fixed at one side of the left V-shaped fixture block (1); the other rack (4) of which teeth are upward is fixed at one side of the right V-shaped fixture block (2); the gear (3) is meshed between the two racks (4); and the right end of the right V-shaped fixture block (2) is connected to the hydraulic cylinder (6) through the push rod (5). By adopting the counter motion automatic centering fixture which is capable of automatically regulating the center, the accuracy of taking the surface of a blank as a localization benchmark is improved, and the problem that the workpiece clamping center deviate is solved and the problems of centering and even clamping when the surface of the blank is taken as the localization benchmark are solved, and thereby, the operation safety and reliability is improved.
Description
Technical field:
The utility model relates to cut-out equipment clamp technology field, is specifically related to a kind of automatically centering fixture.
Background technology:
Be used for fixing processing object in the machine-building process, make it to occupy correct position, the device to accept construction or to detect claims jig again.In a broad sense, any operation in technical process is used for installing rapidly, easily and safely the device of workpiece, all can be described as anchor clamps.For example weld jig, inspection jig, assembling jig, jig etc.Wherein jig is the most common, often abbreviates anchor clamps as.
On automatic machine tool of producing in batches or building-block machine production line, often run into some make the location benchmark with the blank surface irregular rotary part.Because the casting error that this class part itself exists is difficult to satisfy the requirement that evenly clamps neutralizing, and the anchor clamps that cut off equipment at present all do not possess automatic adjusting center function, and operation is inconvenient.
The utility model content:
The purpose of this utility model provides a kind of automatically centering fixture, it can regulate the counter motion automatically centering fixture at center voluntarily, improved the degree of accuracy of making the location benchmark with the blank surface, when having solved that workpiece clamps the difficult problem of misalignment and having made the location benchmark with the blank surface to the even clamping problem that neutralizes, improved processing safety and reliability.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises left V-type fixture block, right V-type fixture block, gear, tooth bar, push rod and hydraulic cylinder, left side V-type fixture block one side is fixed with the downward tooth bar of teeth, right V-type fixture block one side is fixed with the tooth bar that teeth make progress, be engaged with gear between two tooth bars, right V-type fixture block right-hand member is connected with hydraulic cylinder by push rod.
In the utility model, about two V-type fixture blocks always do synchronous backward motion, the clamping of finishing pipe fitting with unclamp action.During clamping, hydraulic cylinder drives push rod and promotes right V-type fixture block and be moved to the left, and the tooth bar of fixedlying connected with it is moved to the left synchronously, drive fixing gear and rotate, thereby upper rack and left V-type fixture block move right, until about two V-type fixture blocks pipe fitting is clamped.In the clamping process, the pipe fitting center is regulated automatically, no matter the pipe fitting diameter, center line all is consistent.When unclamping pipe fitting, push rod spurs right V-type fixture block and moves right, and gear, tooth bar engagement make left V-type fixture block synchronously to left movement, finish pipe fitting and unclamp action, for next charging is prepared.
The utility model can be regulated the counter motion automatically centering fixture at center voluntarily, improved the degree of accuracy of making the location benchmark with the blank surface, when having solved that workpiece clamps the difficult problem of misalignment and having made the location benchmark with the blank surface to the even clamping problem that neutralizes, improved processing safety and reliability.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
With reference to Fig. 1, this specific embodiment is by the following technical solutions: it comprises left V-type fixture block 1, right V-type fixture block 2, gear 3, tooth bar 4, push rod 5 and hydraulic cylinder 6, left side V-type fixture block 1 one sides are fixed with the downward tooth bar of teeth 4, right V-type fixture block 2 one sides are fixed with the tooth bar 4 that teeth make progress, be engaged with gear 3 between two tooth bars 4, right V-type fixture block 2 right-hand members are connected with hydraulic cylinder 6 by push rod 5.
In this specific embodiment, about two V-type fixture blocks always do synchronous backward motion, the clamping of finishing pipe fitting with unclamp action.During clamping, hydraulic cylinder 6 drives push rods 5 and promotes right V-type fixture block 2 and be moved to the left, and the tooth bar 4 of fixedlying connected with it is moved to the left synchronously, drives fixing gear 3 and rotate, thereby upper rack 4 moves right with left V-type fixture block 1, until about two V-type fixture blocks pipe fitting is clamped.In the clamping process, the pipe fitting center is regulated automatically, no matter the pipe fitting diameter, center line all is consistent.When unclamping pipe fitting, the right V-type fixture block 2 of push rod 5 pullings moves right, and gear 3, tooth bar 4 engagements make left V-type fixture block 1 synchronously to left movement, finish pipe fitting and unclamp action, for next charging is prepared.
After clamping action and finishing, workpiece automatic centering, clamping force stepless action about on the two V-type fixture blocks.The clamping accuracy of alignment of workpiece and repetitive positioning accuracy are guaranteed by the clamp body accuracy of manufacture.Concrete for large diameter workpiece clamp, in manufacturing process, adopt whole assembling afterwards to repair the method on V-type fixture block surface, the left and right sides with hard alloy cutter, compensate the fitted position error.By the reconditioning adjusting pad, repetitive positioning accuracy is improved in the adjusting mechanism gap.
This specific embodiment left and right sides V-type fixture block can be regulated in scope of design automatically, makes piece-holder more reliable.The heterodromous automatically centering fixture of two V-type fixture blocks has solved the difficult problem of workpiece clamping misalignment because the uniqueness of structure has improved the degree of accuracy of making the location benchmark with the blank surface, has improved processing safety and reliability.
