Abstract
The utility model discloses a flexible force transmission lever reinforcement centrifugal type elastic chuck easy to reset, which comprises a clamp body, a conical clamp part, a pull rod, a flexible body, a plunger piston and a centrifugal heavy block. The conical clamp part is arranged in a clamp part cavity, and a reset elastic body is arranged between the inner end of the conical clamp part and the inner wall of the clamp part cavity. When the flexible force transmission lever reinforcement centrifugal type elastic chuck easy to reset is used and after processing of a workpiece is finished, the reset elastic body pushes the conical clamp part to be far away from the clamp body under the action of elasticity of the reset elastic body, the flexible force transmission lever reinforcement centrifugal type elastic chuck easy to reset enables the conical clamp body to release the workpiece automatically and reset, takes down the workpiece conveniently, and prepares for next 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 flexible force transmission of being convenient to take off workpiece and resetting.
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, thus the outer round surface of clamping work pieces, and just can carry out cut this moment.Above-mentioned centrifugal collet is after completion of processing; Machine tool chief axis stops the rotation, and relies on taper folder self pyramidal structure to make the taper folder unclamp workpiece, but owing to there is not outer force urges; So the taper folder is slow in one's movements when unclamping, it is not thorough to unclamp; Cause when getting workpiece, will applying certain external force and just can take off, and taper work reset also not thoroughly, when next installation and processing workpiece, also need external force to realize.
Summary of the invention
The purpose of the utility model provides a kind of flexible force transmission of being convenient to reset 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 and centrifugal weight, and said taper folder places in the said folder cavity, is provided with the Flexible Reset body between the inwall of the inner of said taper folder and said folder cavity.
Particularly, said Flexible Reset body is a spring, and said pull bar passes the centre bore of said spring.
Said Flexible Reset body can also be elastoplast, and the two ends of said elastoplast are connected with the inner of said taper folder and the inwall of said folder cavity respectively, and said elastoplast is a plurality of, is uniformly distributed in outside the circumference of said pull bar.
Further; Flexibly connect through said floating lever rod between said centrifugal weight and the said plunger; 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; 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.
The beneficial effect of the utility model is:
When using the utility model, after the workpiece completion of processing, the Flexible Reset body promotes the taper folder down away from clamp body in himself elastic force effect, thereby makes the taper folder discharge workpiece automatically and thoroughly reset, and is convenient to take off workpiece and prepares for next; 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 and centrifugal weight 7; Taper folder 10 places in the folder cavity 12; Be provided with back-moving spring 13 between the inwall of the inner of taper folder 10 and folder cavity 12, pull bar 9 passes the centre bore of spring 13.
In conjunction with accompanying drawing, spring 13 can also be elastoplast, and the two ends of elastoplast are connected with the inner of taper folder 10 and the inwall of folder cavity 12 respectively, and elastoplast is a plurality of, is uniformly distributed in outside the circumference of pull bar 9.
Shown in accompanying drawing; Flexibly connect through floating lever rod 3 between centrifugal weight 7 and the plunger 2; 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; The stage casing of floating lever rod 3 is provided with ellipsoid fulcrum 4, and 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, 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.
After machining, lathe is shut down, and clamp body 1 stops the rotation; Owing to cooperate for non-self-locking between the Outer Taper of taper folder 10 and the folder cavity 12; So under the effect of spring 13, taper folder 10 can recover distortion automatically and be totally released workpiece 11, can take out workpiece 11 this moment; Taper folder 10 also can thoroughly reset, and is convenient to processing next time.
