Abstract

The utility model relates to a hinge rod force amplification centrifugal inner bore clamp. The clamp mainly comprises guide pins, tension springs, two force amplification heavy blocks, hinge rods, a clamp body and two output heavy blocks and is characterized in that the two force amplification heavy blocks and the two output heavy blocks are uniformly distributed in the clamp body around an axis; force is delivered and amplified through the hinge rods between the output heavy blocks and the force amplification heavy blocks; peripheral positions and directions of motion of the output heavy blocks and the force amplification heavy blocks are determined by the guide pins on the clamp body; and the two guide pins on the output heavy blocks simultaneously convey torque. Compared with a centrifugal inner bore clamp which has the same structural weight as the clamp and in which a force amplification mechanism is not provided, the clamp has the advantages that the value of actual output force and the capability of outputting the torque are greatly higher; and therefore, the stability of the clamp is relatively high, and workpieces are machined accurately.

Description

A kind of toggle increasing centrifugal internal clamp
Technical field
The utility model belongs to mechanical field, relates in particular to a kind of toggle increasing centrifugal internal clamp.
Background technology
Along with the raising of scientific and technological level, more and more higher to the requirement of cutting speed, and the required precision of processing is higher, and this just needs revolution class fixture can keep larger clamping force under fast state.Force-increasing mechanism is as the clamp mechanism of jig, extensively exists in all kinds of jigs, and along with the development of the more and more higher of cutting speed and heavy industry, also more and more higher to the requirement of force-increasing mechanism clamping force.Common force-increasing mechanism folder power under fast state is large not, and its stability can not well be ensured, makes the precision of workpiece processing receive impact.Force-increasing mechanism in being widely used in Machine Tool Fixture Design, have a wide range of applications equally in locking, location and the clamped design of locking mechanism for machine tool design and other all kinds machineries.
The utility model content
For the problems referred to above, the utility model provides a kind of toggle increasing centrifugal internal clamp, has solved for same structure weight but there is no the centrifugal internal clamp of force-increasing mechanism, strengthens the problems such as ability of actual power output and output torque.
For realizing above purpose, by the following technical solutions: a kind of toggle increasing centrifugal internal clamp, it mainly comprises guide finger, tension spring, force amplifying weight, toggle, clamp body, Driving weight; Two Driving weights and two force amplifying weights are around the axle center, be evenly distributed in clamp body, Driving weight and force amplifying weight, carry out transmission and the expansion of power both by toggle, circumferential position and the direction of motion are definite by the guide finger on clamp body, and two guide fingers on Driving weight are born the task of transmitting torque simultaneously.
The quantity of the guide finger of described each Driving weight guiding is two.
The quantity of the guide finger of described each force amplifying weight guiding is one.
The utility model advantage: with respect to same structure weight but there is no the centrifugal internal clamp of force-increasing mechanism, the numerical value of actual power output is much bigger, and it is large many that ability of its output torque is also wanted, and makes its stability better, and workpiece processing is more accurate.

The specific embodiment
Embodiment 1
Driving weight (6) and force amplifying weight (3) carry out transmission and the expansion of power by toggle (4) between both.Circumferential position and the direction of motion of Driving weight (6) and force amplifying weight (3) are determined by the guide finger (l) that is fixed on clamp body (5); Two guide fingers (1) on Driving weight (6) are born the task of transmitting torque simultaneously.During normal operation, the exterior arc surface of Driving weight (6) and workpiece (7) inwall keep in touch, and force amplifying weight (3) is discontiguous with workpiece (7) inwall all the time.Workpiece (7) endoporus is located on the outer cylinder surface of clamp body (5) with less gap.When clamp body (5) rotates, force amplifying weight (3) and Driving weight (6) just produce respectively centrifugal force Fc1, Fc2, after the angular velocity omega of clamp body (5) reaches certain value, under the effect of centrifugal force, the exterior arc surface of Driving weight (6) just begins to contact with workpiece (7) inwall, and it is applied active force, thereby drive itself and clamp body (5) synchronous rotary in the same way, process is flutterred the moment of friction that the latter two the frictional force of asking generation of beginning forms and is just resisted the cutting moment that is formed by cutting force.Driving weight (6) applies directed force F to workpiece and is comprised of following two parts, first be the centrifugal force Fc2 that produces of Driving weight self with the active force of spring (2) with joint efforts; Second portion is the centrifugal force Fc1 that force amplifying weight (3) produces, and after quadrature force-increasing mechanism reinforcement, acts on Driving weight (6) direction of motion Fc2 and be the component on direction.

Claims (3)
