Abstract
The utility model discloses an adjustable automatic centering spindle, wherein two guide rail seats are symmetrically and fixedly arranged at two ends of a central shaft through keys; the central shaft between the two guide rail seats is provided with a spacer bush; three guide rails are arranged on the outer side face of each guide rail seat along the radius direction; a slide block is only arranged on each guide rail; an adjustable clamping jaw is fixedly arranged on each slide block through a bolt; the two ends of the central shaft are provided with a bowl-shaped spring respectively; and a washer and a pressing nut are arranged on the central shaft on the outer side of each bowl-shaped spring respectively. The adjustable automatic centering spindle has the advantages of simple structure, convenience in use, large clamping force, capability of automatically realizing centering and high centering accuracy.
Description
Technical field
The utility model relates to a kind of machining frock, is specifically related to adjustable self-centering mandrel, belongs to mechanical processing technique equipment technology field.
Background technology
In machining work process, in order to process pipe class workpiece, generally to fix a mandrel in the central axis position installation of pipe class workpiece, existing mandrel is all generally the version of fixing, can't do corresponding adjusting according to the diameter of bore of different workpieces, cause specifications and models more, not only the manufacturing cost of equipment higher, use trouble, also be unfavorable for management simultaneously; Although, also there are some can the adjustable type mandrel in existing technology, but, the adjustable mandrel of this class generally exists adjustable range less, so, still have that the specification kind is more, manufacturing cost is higher, use trouble, be unfavorable for the defective of managing, in addition, generally also there is the defective that centering precision is relatively poor, be not suitable for being applied to the larger workpiece of diameter in this class mandrel.
Summary of the invention
The purpose of this utility model is: for the existing defects of existing mandrel, the utility model provides a kind of novel adjustable self-centering mandrel, overcomes the existing existing defects of mandrel.
the technical scheme that the above-mentioned purpose that realizes the utility model adopts is: described a kind of adjustable self-centering mandrel, it is by central shaft, spacer, clamp nut, packing ring, bowl type spring, adjustable jaw, slide block, guide rail, track base, key forms, it is characterized in that: two track bases are fixed on the two ends of central shaft symmetrically by key, arrange on the central shaft between two track bases a spacer is installed, along radial direction, three guide rails are set at the lateral surface of each track base, angle between each guide rail equates, arrange on each guide rail a slide block is installed, install by bolt above slide block only at each and fix an adjustable jaw, arrange respectively at the two ends of central shaft a bowl type spring is installed, the rim of a bowl position of described bowl type spring is connected to the seam position of slide block, arrange respectively on the central shaft in each bowl type spring outside a packing ring and clamp nut are installed.
Beneficial effect: in the utility model, when needs clamp the cylindrical workpiece of different-diameter, only needing the adjustable jaw of adjusting in advance or replacing different length is available achieving the goal, and impel bowl distortion of type spring by clamp nut, thereby promote the purpose that the outside mode of sliding of slide block reaches clamping work pieces, so, can be found out by structure principle chart of the present utility model and operation principle, the utlity model has simple in structure, easy to use, clamping force large, can automatically realize the purpose of feeling relieved and the higher advantage of centering precision.
