Outside, the piston rod is arranged in base center and upper end is stretched into plunger rod, and the outer ring of the plunger rod is matched successively outward
Trap is equipped with collet chuck and taper sheath, which is characterized in that resetting spring, the work are provided between the piston rod and plunger rod
Be arranged at the top of stopper rod between the outer wall of connector and connector and plunger rod inner wall is clearance fit, the top of the connector
Portion extends outward to form limited step, and the top of the plunger rod, which is screwed and sealed by screw thread, is fixed with supporting block, the branch
It is provided with rising spring between the bottom surface of bracer and the top surface of connector and the rising spring is in compressive state.
The technique effect of this frock clamp auxiliary hydraulic support cylinder is：It is used relative to traditional frock clamp Auxiliary support
It after spring jacks up fulcrum, is then fixed with screw side single-point, efficiency is low, and when side screw is fixed, fulcrum will produce up and down
It is mobile, so that workpiece is deformed, vibrate, support accuracy is poor, and hydraulic oil enters to push in cylinder body from pedestal and live in the utility model
Stopper rod rises, and the compression degree for rising spring increases and plunger rod is driven to rise, and one is provided for workpieces processing by rising spring
A adaptive support, it can make up the size difference of workpiece, and supporting point is made accurately to rest on ideal position, and workpiece is in
After accurate positionin, the supporting point of hydraulic support cylinder is locked plunger rod in the position by hydraulic radial force-fitting taper sheath and collet chuck
It sets, increases the rigidity of fixture, supporting point not will produce movement, and hydraulic oil release reflux when reset, radial hydraulic pressure gradually disappears
Collet chuck release is lost, the resetting spring in compressive state makes it decline reset by piston rod dry rise, further, in order to
It prevents from rising spring dynamics excessive the generations dislocation that is squeezed to deform, the top of connector and connector is provided at the top of piston rod
Portion extends outward to form limited step, can effectively prevent rising the unbalance stress generation dislocation change of spring bottom surface by limited step
Shape increases its service life.
In a kind of above-mentioned frock clamp auxiliary hydraulic support cylinder, contact of the upper end with plunger rod in the cylinder body
Snap ring is provided on face.Snap ring setting, which can further increase its rigidity and can prevent extraneous dust from entering in cylinder body, to be influenced
Its using effect.
In a kind of above-mentioned frock clamp auxiliary hydraulic support cylinder, the bottom surface of the pedestal is fixed with sealing cover, and
Sealing cover center has oil filler point.Hydraulic oil is injected into cylinder body by oil filler point and rises collet chuck radial closure with piston.
In a kind of above-mentioned frock clamp auxiliary hydraulic support cylinder, the lower end of the piston rod outwardly protrudes to form one
The spacing collar of body formula structure.Piston rod can be effectively prevent to rise too high by the setting of spacing collar makes contained spring excessive extrusion
Generated elastic effect declines.
In a kind of above-mentioned frock clamp auxiliary hydraulic support cylinder, the bottom surface of the piston rod offers flat recess.
The design of the structure can be such that it is more uniformly stressed, and facilitate later period maintenance.
Compared with prior art, this frock clamp auxiliary makes it with hydraulic support cylinder by being improved to its internal structure
Have the advantages that structure more adequate service life is longer.
