Abstract
The utility model discloses a low-resistance flexible force-transferring lever reinforcing centrifugal flexible chuck. The low-resistance flexible force-transferring lever reinforcing centrifugal flexible chuck comprises a fixture body, a conical clamp body, a pull rod, a flexible body, a plunger, a centrifugal heavy block and a floating lever, wherein a position in the fixture body positioned between the centrifugal heavy block and the plunger is provided with a lever hollow cavity used for placing the floating lever; the centrifugal heavy block is movably connected with the plunger through the floating lever; the middle section of the floating lever is provided with a cone fulcrum; the distance between the upper end and the lower end of the cone fulcrum is greater than the diameter of the floating lever; and the upper end and the lower end of the cone fulcrum are cone apexes and are contacted with the inner wall of the lever hollow cavity. The low-resistance flexible force-transferring lever reinforcing centrifugal flexible chuck adopts a through structure of the floating lever, the radius of the center of mass can be automatically balanced, the fulcrums of the middle section of the floating lever is changed into the cone fulcrum with an extremely small contact area, and the friction resistance is reduced, so that the low-resistance flexible force-transferring lever reinforcing centrifugal flexible chuck has the advantages of compact structure, low force-transferring resistance and reliable operation.
Description
Technical field
The utility model relates to a kind of centrifugal collet, relates in particular to the lever augmented centrifugal collet of a kind of slight drag flexible force transmission.
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, and centrifugal weight causes the power transmission resistance to increase rotating when moving and might rubbing with the pouring weight inwall.
Summary of the invention
The purpose of the utility model provides a kind of slight drag flexible force transmission lever augmented centrifugal collet with regard to being in order to address the above problem.
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, centrifugal weight and 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 centrum fulcrum; The upper and lower side distance of said centrum fulcrum is greater than the diameter of said floating lever rod, and the upper and lower side of said centrum fulcrum is and is the centrum summit, and the upper and lower side of said centrum fulcrum contacts with said lever cavity inner wall.
Further, said centrifugal weight is a cylinder, and said centrifugal weight is provided with roller away from the surface of said plunger one side.
As preferably, said floating lever rod is cylindrical lever, and said lever cavity is a cylindrical cavity.
The beneficial effect of the utility model is:
The utility model adopts this through structure of floating lever rod; But barycenter radius autobalance; And changing the fulcrum in floating lever rod stage casing into contact area very little centrum fulcrum, frictional resistance reduces, so the utility model compact conformation, little, the reliable operation of power transmission resistance.
Description of drawings
Fig. 1 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 centrum fulcrum 4; The upper and lower side distance of centrum fulcrum 4 is greater than the diameter of floating lever rod 3, and the upper and lower side of centrum fulcrum 4 is and is the centrum summit, and the upper and lower side of centrum fulcrum 4 contacts with the inwall of lever cavity 5.
Shown in accompanying drawing, centrifugal weight 7 is a cylinder, and centrifugal weight 7 is provided with roller 13 away from the surface of plunger 2 one sides.
Shown in accompanying drawing, floating lever rod 3 is cylindrical lever, and lever cavity 5 is a cylindrical cavity.
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; Compressed flexible body 8, flexible body 8 pushing drawing rods 9 are moved to the left, and pull bar 9 drives taper folder 10 and is moved to the left; Under the effect of folder cavity 12; Taper folder 10 is compressed, powerful clamping work pieces 11, and 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.
