Abstract
The utility model discloses a flexible force transmission lever force-increasing centrifugal flexible chuck which comprises a fixture body, a tapered clamp piece, a draw bar, a flexible body, a plunger piston and a centrifugal weight, and is characterized by further comprising a floating lever; a lever cavity used for containing the floating lever is arranged between the centrifugal weight and the plunger piston in the fixture body; the centrifugal weight is movably connected with the plunger piston by the floating lever; the middle section of the floating lever is provided with an ellipsoid support point; the diameters of the upper end and the lower end of the ellipsoid support point are larger than that of the floating lever; and the upper end and the lower end of the ellipsoid support point are contacted with the inner wall of the lever cavity. After a through-type structure of the floating lever, the radius of the center of mass can be automatically balanced; and furthermore, the structure is greatly simplified, and the flexible chuck is low in processing requirement, compact in structure, good in safety and reliable in work.
Description
Technical field
The utility model relates to a kind of centrifugal collet, relate in particular to a kind of simple in structure, be convenient to the centrifugal collet of processing flexibility and processing force transferring lever reinforcement.
Background technology
Centrifugal collet is used for clamping work pieces and drives workpiece rotating together, in rotary course, workpiece is carried out cut.Present centrifugal collet, its operation principle is: clamp body connects with seam and lathe ring flange or spindle taper hole, and workpiece is a benchmark with semi-finished cylindrical, under the less condition in gap, inserts the tapered clamp part; After lathe drive anchor clamps began rotation, several centrifugal weights were done swing counterclockwise around bearing pin under action of centrifugal force, and plunger is oppressed in its left part, and plunger is the compressed flexible medium then, forced pull bar to drive the taper folder and moved to left; The taper folder then receives the effect of folder cavity and produces distortion, thereby the outer round surface of clamping work pieces just can carry out cut this moment; Machine tool chief axis stops the rotation after the completion of processing, owing to cooperates for non-self-locking between taper folder Outer Taper and the folder cavity, so the taper folder can automatic recovery is out of shape and unclamps workpiece.Adopt bearing pin as pivot point between the centrifugal weight of above-mentioned centrifugal collet and the plunger,, need pouring weight is proposed the higher requirement that cooperates with the relative motion position of clamp body and bearing pin in order to prevent the contingent catching phenomenon of pouring weight slippage; In addition, the complex geometry of the centrifugal weight of existing centrifugal collet, anufacturability is bad.
Summary of the invention
The purpose of the utility model with regard to be to provide in order to address the above problem a kind of simple in structure, be convenient to the centrifugal collet of processing flexibility and processing force transferring lever reinforcement.
The utility model is realized above-mentioned purpose through following technical scheme:
The utility model comprises clamp body, taper folder, pull bar, flexible body, plunger and centrifugal weight; The utility model also comprises floating lever rod; Position in the said clamp body between said centrifugal weight and said plunger is provided with the lever cavity that is used to place said floating lever rod; Flexibly connect through said floating lever rod between said centrifugal weight and the said plunger; The stage casing of said floating lever rod is provided with the ellipsoid fulcrum, and the upper and lower side diameter of said ellipsoid fulcrum is greater than the diameter of said floating lever rod, and the upper and lower side of said ellipsoid fulcrum contacts with said lever cavity inner wall.
Further, said floating lever rod is cylindrical lever, and said lever cavity is a cylindrical cavity.
Further, said centrifugal weight is a cylinder.
The beneficial effect of the utility model is:
The utility model adopts this through structure of floating lever rod, but barycenter radius autobalance, and also structure is simplified greatly, processing request is low, compact conformation, good, the reliable operation of security.
Description of drawings
Accompanying drawing is the sectional structure sketch map of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Shown in accompanying drawing, the utility model is not included fully among the figure, be the line of demarcation with the axis of taper folder 10, below not shown part and top symmetrical configuration.The utility model comprises clamp body 1, taper folder 10, pull bar 9, flexible body 8, plunger 2, centrifugal weight 7 and floating lever rod 3; Position in the clamp body 1 between centrifugal weight 7 and plunger 2 is provided with the lever cavity 5 that is used to place floating lever rod 3; Flexibly connect through floating lever rod 3 between centrifugal weight 7 and the plunger 2; The stage casing of floating lever rod 3 is provided with ellipsoid fulcrum 4; The upper and lower side diameter of ellipsoid fulcrum 4 is greater than the diameter of floating lever rod 3, and the upper and lower side of ellipsoid fulcrum 4 contacts with the inwall of lever cavity 5.
Shown in accompanying drawing, floating lever rod 3 is cylindrical lever, and lever cavity 5 is a cylindrical cavity; Centrifugal weight 7 is a cylinder.
Shown in accompanying drawing, after lathe drive clamp body 1 began rotation, centrifugal weight 7 was under action of centrifugal force; Radially outwards move (i.e. top among the figure) in pouring weight cavity 6, and centrifugal force acts on plunger 2 through floating lever rod 3, forces plunger 2 to axis direction (i.e. below among the figure) motion; Inner end face pushing drawing rod 9 through plunger 2 is moved to the left; Pull bar 9 drives taper folder 10 and is moved to the left, and under the effect of folder cavity 12, taper folder 10 is compressed; Powerful clamping work pieces 11, can carry out cut this moment.
Shown in accompanying drawing, after machining, lathe is shut down, and clamp body 1 stops the rotation owing to cooperates for non-self-locking between the Outer Taper of taper folder 10 and the folder cavity 12, so taper folder 10 automatically recovery be out of shape and unclamp workpiece 11, can take out workpiece 11 at this moment.
