According to storage in a computer, ensure the trackability of Product processing data, be easy to quality of production control management；Due to machine in itself
Just there is accurate pressure and Bit andits control function, so need not stiffened is spacing in frock in addition, processing different size produce
Different press fitting programs need to be only called during product.
CN106873496A discloses one kind and is based on PLC and servo-controlled hydraulic cylinder assembling machine, from PLC as control core
The heart, corresponding servo swivel head and tightening axle are configured, the size of Bolt Tightening Force is accurately controlled by the feedback of tightening axle, this
Sample can not only avoid more bolt locking cylinder handmade rotary problems, and can also solve cylinder seal unbalance stress influences the oil cylinder longevity
The problem of ordering and be safe.
But the pressure detecting of electrical servo pressing machine is carried out in the outside of output shaft at present, detection is inaccurate, peace
Full property is poor, and power output is not sufficiently stable.
The content of the invention
The utility model is directed to existing pressing machine existing deficiency in terms of pressure detecting, there is provided a kind of power output is stable
Reliable displacement and the electronic pressing machine output axle construction of the accurate built in pressure sensor of Stress control.
The electronic pressing machine output axle construction of built in pressure sensor of the present utility model, using following technical proposals：
The output axle construction, including cylinder barrel, Fitted Axles, screw pair, force snesor and bearing block；Bearing block is connected to
Cylinder barrel one end, screw pair and Fitted Axles are installed in cylinder barrel, and Fitted Axles are connected with screw pair, are provided with leading screw
Force snesor, both sides are mounted on thrust bearing above and below force snesor on leading screw.
Leading screw in the screw pair is arranged in cylinder barrel by the bearing in bearing block, the spiral shell in screw pair
Mother is fixedly mounted in the endoporus of Fitted Axles.
Bearing in the bearing block uses a pair of NU cylinder roller bearings.NU cylinder roller bearings have two pairs in outer ring
Flange, inner ring is without rib, it is allowed to which axle produces axial displacement relative between bearing block in both direction.
The Fitted Axles are arranged on and are arranged in the end cap of cylinder barrel lower end, to realize radial positioning.
Antirotation keys are set between the Fitted Axles and cylinder barrel.
Guide sleeve is provided between the Fitted Axles and cylinder barrel, is play the guiding role when Fitted Axles move.
During operation, leading screw is in situ under transmission mechanism driving to be rotated, and Fitted Axles move axially therewith.The thrust transmission of leading screw
To thrust bearing, thrust bearing transmits the force to force snesor, and the axial micro-displacement of force snesor can be by bearing block
Bearing movement.
Force snesor is built in cylinder barrel in the utility model, is directly installed on leading screw, realizes the accurate of Fitted Axles
Displacement and the accurate detection of pressure assembling force, transmission torque is big, ensure that Fitted Axles stable and reliable operation.
