Description
Technical field
The present invention relates to friction-welding machine and manufacture field, particularly relate to friction-welding machine hydraulic chuck.
Background technology
The hydraulic chuck of prior art, in most employing main shaft, pull bar is set, pull bar is driven by angling cylinder, pull bar drives and pulls main ram 1 to move forward and backward, main ram 1 is driven by lozenges and moves up and down from ram 2, jaw 3 is connected to from ram 2, and retinue's ram moves up and down, and realizes the clamping of workpiece and unclamps.But its shortcoming existed is, clamping force is less, and clamping welding work pieces is not firm, and workpiece easily skids, and causes damage to workpiece and jaw; Clamping accuracy is not high, can not realize the high progress location to workpiece; Take main shaft inner space: angling cylinder is connected on main ram by the pull bar of inner hole of spindle, and inner hole of spindle does not have space mounting axial positioning mechanism; Security is not high: when welding operationally, unexpected power-off or oil cylinder stuck, the workpiece of High Rotation Speed can fly out in chuck, is easily becoming great potential safety hazard.Have much room for improvement.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of effectively raising clamp precision and chucking power, the friction-welding machine disk spring type wedge shape hydraulic chuck preventing workpiece from skidding accidents caused.
Key problem in technology of the present invention is that changing prior art utilizes pull bar to carry out locking and unclamping the structure of chuck, and change and utilize disc spring structure to lock, push action cylinder unclamps, and effectively prevents power-off or the stuck hidden danger causing workpiece to fly out of oil cylinder.Its concrete technical scheme is: friction-welding machine disk spring type wedge shape hydraulic chuck, comprise main shaft, the push action cylinder be connected with front-end of spindle, main ram, from ram and fixture block, bottom described main ram, tapered ramp is engaged with from ram top tapered ramp, fixture block is installed on from ram leading section, it is characterized in that separately being provided with pushing away seat, push away the cylinder-like structure that seat is flanged limit, leading section, push away base rear end center and offer through hole, described through hole internal fixtion is connected with ring flange, described pushing away in a cylindrical shell is provided with disc spring structure, described disc spring vibrational power flow is above the flange of ring flange, disc spring structure end is fixed on and pushes away rearward end in a cylindrical shell, disc spring structure front end is connected in the main ram pushed away in a cylindrical shell, describedly be arranged at ring flange rear from ram, described push action cylinder correspondence is arranged at the rear pushing away a flange.
As preferably, around pushing away a center of circle, to arrange oil cylinder quantity according to applying working condition different set be 6 ~ 12 to described push action cylinder.
As preferably, described fixture block is set to 3.
As preferably, described disc spring structure is set to 3 groups around axle center, and often group arranges 3.
As preferably, in described disc spring structure, be provided with 9 disc springs.
Beneficial effect of the present invention: the present invention effectively prevents workpiece from flying out, substantially increases chucking power and effectively prevents workpiece from crushing.Jaw is built-in, and rigidity is higher, and clamping force is reliable, and clamping is stable, and workpiece is non-slip; Built-in jaw, quality of fit is higher, can realize precise positioning; Realize Workpiece clamping by external oil cylinder, do not occupy front-end of spindle inner space, facilitate main shaft that axial positioning mechanism is installed; During Workpiece clamping, by the elastic deformation clamping work pieces of butterfly spring, depart from oil cylinder or power supply, security is higher.
