Description
Technical field
The utility model relates to the anchor clamps that a kind of Digit Control Machine Tool is used, and especially relates to a kind of crucible milling flexible fixture.
Background technology
After silica crucible is produced,, at first to carry out cutting process to silica crucible according to dimensional requirement; At present; Prior art is the fixed dimension anchor clamps to the anchor clamps in the cutting process process of silica crucible, and inconvenient operation can not adapt to the cutting processing of the silica crucible of different size size; When silica crucible that the need cut lengths vary in size, will change the different anchor clamps of size; So not only increased working strength of workers, and manufacturer will drop into the anchor clamps that more fund is bought many different sizes, waste substantial contribution.Chinese patent discloses a kind of adjustable crucible anchor clamps (Granted publication number: CN201921704U); It comprises left side arm, right arm, sliding sleeve and steady pin, and the end, rear end of left side arm and right arm is fixed together, and left side arm and right arm are symmetrical set; The front end of left side arm and right arm is respectively semi arch; The rear end of left side arm and right arm expands outwardly from top to bottom gradually, and sliding sleeve is placed in the rear end of left side arm and right arm, and the rear end of left side arm and right arm correspondence respectively is provided with shifting chute; Shifting chute is for to be made up of a plurality of circular holes that are connected, and steady pin is arranged in the shifting chute; Bottom one side of steady pin is provided with convexity, and the top of steady pin links to each other with sliding sleeve through iron chains.But the structure of this anchor clamps is comparatively simple, can only be used for clamping circular crucible, and the scope of application is less.
The utility model content
The utility model provides a kind of crucible milling flexible fixture, and it mainly is that to solve the structure of existing in prior technology anchor clamps comparatively simple, can only be used for clamping circular crucible, the technical problem of the less grade of the scope of application.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
The crucible milling flexible fixture of the utility model comprises base plate and top cover, is connected with column between base plate and the top cover; Be provided with driving cam between described base plate and the top cover, driving cam connects drive unit, and the driving cam edge is provided with the projection more than 3; Each projection has all contacted a roller, and each roller all is connected on the roller mount, and roller mount is connected with push rod; Push rod is connected on the column through the push rod holder, and the outer end of push rod connects jacking block through the jacking block seat.After drive unit drove the driving cam rotation, driving cam rotated a certain angle, and projection promotes roller and outwards moves; Thereby push rod is protruding; The jacking block of push rod outer end just can contact on the inner surface of crucible, because push rod is more than 3, therefore can carry out clamping action to crucible.Through the push rod more than 3 that can arbitrarily stretch, can different size, difform crucible be clamped, applicable scope is bigger.Projection can be an arc, and roller can more successfully roll on cam like this.
As preferably, described drive unit includes the power transmission shaft that is connected with driving cam, and power transmission shaft is hinged with connecting rod, and the connecting rod other end is hinged with cylinder through cylinder connection piece, and cylinder is fixed on the base plate through the cylinder support.After cylinder started, its ejecting rod of cylinder made power transmission shaft rotate through connecting rod, and then makes driving cam rotate to an angle, and push rod just can protrudingly be clamped crucible.When cylinder resetted, ejecting rod of cylinder was retreated, and driving cam just can the reverse rotation certain angle, and push rod inwardly shrinks and unclamps crucible.
As preferably, described power transmission shaft outer surface is provided with bearing block, and bearing block is connected on the base plate through bearing bracket.Be provided with bearing in the bearing block, can be so that power transmission shaft be more smooth and easy rotatably.
As preferably, be provided with jacking block adjustment seat between described push rod and the jacking block seat.Can be provided with the adjustment nut on the jacking block adjustment seat, be used for regulating the distance between jacking block seat and the push rod outer end, thereby can be suitable for the demand that clamps of different size crucible.
As preferably, described projection is 4 that are uniformly distributed with, and corresponding push rod also is 4.Base plate and top cover are rectangle, and push rod is distributed on the diagonal of rectangle, and 4 jacking blocks are positioned on 4 angles of rectangle, and are more firm to clamping of crucible like this.
Therefore, the push rod that the utility model utilizes cam can drive more than 3 simultaneously clamps crucible, can be suitable for the demand that clamps of different size, different size crucible like this, and the scope of application is bigger, and is simple and reasonable for structure.
