Description
Technical field
The utility model is related to a kind of for correcting the mechanical equipment of the morpheme meter of machined part；Specifically valve
The oscillating arm mechanisms of straightener.
Background technology
Patent CN201410405107.4 discloses a kind of valve straightener of three axis correction, this patent specification section
It falls and points out that the 4th axis that is movable and playing alignment is by eccentric wheel 13, limiting pressure roller 17, swing rod 14 and constant force cylinder 15
Interaction generates movement, employs lever principle, is mechanical drive mechanism；Engine valve stem is slim-lined construction, after being squeezed
It also occur that rebound, reaches design requirement for the geometric tolerance after engine valve stem is enabled to spring back, so, during design, it is necessary to
The movement endpoint of 4th axis is leaned on forward so that then geometric tolerance during extruding is waited to recoil to rational beyond requirement
In the range of Geometrical Tolerance Principle；Popular says, is not bar portion arches upward how many, equipment squeeze it is straight how many, but than bar portion central shaft
Line further along more to be squeezed directly；This design can to produce new stress concentration on the extruded part of engine valve stem, have
It damages in tensile strength and fatigue limit.
Invention content
For the utility model in view of the shortcomings of the prior art, correction mass can be promoted by providing, setting squeezes the alignment time, is protecting
Under conditions of demonstrate,proving geometric tolerance, the oscillating arm mechanisms that valve stem local stress does not damage the valve straightener of valve are reduced.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals：Valve straightener
Oscillating arm mechanisms, including a swing arm, the swing arm includes a pair of of forearm, center spreader and a pair of of postbrachium, before two described
Arm middle frame is equipped with alignment axis, and correction cone pulley, lock washer, locking flange and two alignments are sequentially arranged on the alignment axis
Roller, the lock washer and the locking flange fix the correction cone pulley jointly, and wherein one end of the alignment axis is exposed
One of forearm is simultaneously equipped with locking handwheel in end point, and the inner cavity of the center spreader is provided with swing arm locating shaft, described
Swing arm is swung centered on the swing arm locating shaft, and swivel is clamped between two postbrachiums, and the rotation connects
Driving mechanism is installed on head.
The driving mechanism includes oil cylinder and oil cylinder seat, and the oil cylinder is mounted in the oil cylinder seat, the oil cylinder front end
It is connected on the swivel by piston rod；The rear end of the oil cylinder seat is equipped with adjusting screw, pacifies on the adjusting screw
Equipped with adjustment gear disk, the adjustment gear disk is connected by transmission gear with adjusting scale gear.
The driving mechanism includes servo motor and motor cabinet, and the servo motor is mounted on the motor cabinet, described
The telescopic head of servo motor is mounted on the swivel.
In order to reach accurate correction, oil cylinder or Serve Motor Control is controlled by rotary encoder.
The utility model compared with prior art, has the advantages that：By rotary encoder setting range in oil
Under the work done of cylinder or servo motor, swing arm is swung, the alignment roller on alignment axis and correction cone pulley ferry-boat to setting
Determine operating position, swing arm is swung, and can be realized after straightening-wheel contact valve and be squeezed at a slow speed, straightening-wheel is straightened cone pulley according to gas
Door rod and the rotary speed of disk and after rotation is depressed beyond Geometrical Tolerance Principle respectively, back out valve at a slow speed, then give up the throne soon；When
Between efficiency improve, valve precision improve；Protect the tensile strength of valve, fatigue strength improve and it is easy to adjust precisely；Jointly
Fixed correction cone pulley can resist the stress axially or radially of correction cone pulley, will not be subjected to displacement.
