Detailed description of the invention
Embodiment in is by reference to the accompanying drawings further described by the present invention below:
As shown in Figure 3, comprise chuck body 1, drive end bearing bracket 2, unclamp dish 3, three slides 4, three claws 5, three tapered wedges 6, ring flange 7, nine groups of disc spring mechanisms 8, cylinder pedestal 9, ten small oil tank cylinder bodies 10, ten small oil tank cylinder caps 11, ten small oil tank pistons 12, ten springs 13 etc.
The present invention includes chuck and oil cylinder two parts composition; Chuck segment is divided in spindle nose, and oil cylinder part is loaded on headstock position.
Described chuck part by chuck body 1, drive end bearing bracket 2, unclamp dish 3, three slides 4, three claws 5, three tapered wedges 6, ring flange 7 and nine groups of disc spring mechanisms 8 and form chuck main body, described ring flange 7 is passed by the screw that penetrates on chuck body 1, be fixed with main shaft and connect, three straight troughs are offered in chuck body 1 front end, article three, in straight trough, three slides 4 are installed, three slides 4 are connected with three tapered wedges 6 by skewed slot, three slides 4 are connected with three claws 5 by screw at drive end bearing bracket 2 place, drive end bearing bracket 2 and unclamp between dish 3 and be provided with nine groups of disc spring mechanisms 8, unclamping dish 3 drives the reciprocal axial motion of three tapered wedges 6 can be converted into the radial direction reciprocating motion of three slides 4, nine groups of disc spring mechanisms 8 are fixed on unclamps on dish 3, slide in chuck body 1 and unclamp action as compression.Strutted by nine groups of disc spring mechanisms 8, make to unclamp dish 3 and drive three tapered wedges 6 to move towards away from drive end bearing bracket 2 direction, now three tapered wedges 6 and three slide 4 slides utilize wedge angle that relative displacement occurs, thus realize clamping function; Otherwise compressed by nine groups of disc spring mechanisms 8, make to unclamp dish 3 and drive three tapered wedges 6 towards the motion of drive end bearing bracket 2 direction, now three tapered wedges 6 and three slides 4 utilize wedge angle that relative displacement occurs, thus realize release function.Described three slides 4 are provided with wedge angle respectively and between three tapered wedges 6; Described wedge angle is 10 ° ~ 15 °.
Each group disc spring mechanism 8 described is by several disc springs, two adjusting washer (disk)s, axis of guides, and an attachment screw composition.
Described oil cylinder part is made up of cylinder pedestal 9, ten cylinder parts, and described ten cylinder parts are uniform to be respectively arranged on cylinder pedestal 9, and is connected with cylinder pedestal 9 is uniform; Described ten cylinder parts comprise ten cylinder blocks, 10, ten oil cylinder cylinder caps, 11, ten oil cylinder pistons, 12, ten springs 13.
Described ten oil cylinder pistons 12 are set with ten springs 13, and are arranged in ten cylinder blocks 10 respectively, between described cylinder cap 11 and cylinder body 10, seal is housed, between described ten oil cylinder cylinder caps 11 and ten cylinder blocks 10, adopt fastener bolt fastening; Joining oil by cylinder pedestal 9 makes the piston of each cylinder part upwards eject, and the dish 3 that unclamps promoted on chuck reaches the object that chuck unclamps.
Operation principle of the present invention:
This friction welding spring powered chuck of the present invention is divided into two parts, and chuck segment is divided in spindle nose, and oil cylinder part is loaded on headstock position.There is large through-hole in the middle of chuck, by larger-diameter part, match with numerically controlled lathe.Hydraulic oil of the present invention is joined oil by cylinder pedestal and is entered each small oil tank cylinder body, the piston of each small oil tank is upwards ejected, the tension force overcoming chuck disc spring mechanism promotes unclamping of chuck and coils and drive tapered wedges to move right, then makes slide unclamp motion together with claw generation by the skewed slot on tapered wedges.When stopping joining oil, the restoring force that chuck disc spring mechanism produces promotes to unclamp coil and drive tapered wedges to be moved to the left, then makes slide produce clamping movement together with claw by the skewed slot on tapered wedges.
The present invention at high operating temperatures, because oil cylinder does not contact processing work, without the need to considering temperature rise, long service life, and chuck adopts high temperature resistant material, coordinative composition of equipments.And clamping force adjustable, matching with numerically controlled lathe, is the most excellent equipment of processing friction welding class workpiece.
