Among the figure: 1 trombone slide, 2 adapter sleeves, 3 sliding shoes, 31 inclined-planes, 4 bases, 5 springs, 6 spring bases, 7 stop screws, 8 fulcrum shafts, 9 limiting brackets, 10 rocker pieces, 101 projectioies, 11 claws, the tight arm swing oil cylinder of 12 strap clamps, 121 clamp arms, 13 positioning sleeves, 14 locating pieces, 15 screws, 16 main shafts, 17 workpiece, 18 main spindle boxes, 19 end caps.
The specific embodiment
As shown in Figure 1, 2, the unsteady hydraulically operated fixture of this lathe mainly comprises base 4, drive link, sliding shoe 3, rocker piece 10, a plurality of claw 11.Wherein drive link is a trombone slide 1.
One end of base 4 is provided with bolt connecting hole, is connected with the main shaft bolt of lathe by this bolt connecting hole when installing and using.For cooperating with existing main shaft, the end face of base 4 is provided with the taper hole with the spindle nose taper fit.The other end fixed installation limiting bracket 9 of base 4.
Trombone slide 1 and main shaft 16 are coaxial and be arranged in the main shaft 16, between trombone slide 1 and the main shaft 16 for being slidingly matched.One end of trombone slide 1 is connected with the output of a hydraulic jack, drives trombone slide by hydraulic jack and slides vertically.The other end of trombone slide 1 is connected with adapter sleeve 2 by external screw thread, adapter sleeve 2 cylindricals be provided with step with in 3 corresponding connections of sliding shoe between base 4 and the limiting bracket 9, the end end face that the diameter in the hole that cooperates with adapter sleeve on the sliding shoe 3 is big is provided with end cap 19.Trombone slide can drive sliding shoe 3 move left and right by adapter sleeve like this.
All claws are around the uniform setting of main-shaft axis.Each claw 11 is installed in an end of a lever rocker piece 10.The fulcrum shaft 8 of rocker piece 10 is fixed on the limiting bracket 9.The other end of rocker piece 10 is a drive end, and drive end is provided with projection 101 near a side of spindle axis, and the inclined-plane 31 that the cylindrical upper edge main shaft of this projection and sliding shoe 3 axially is provided with is slidingly connected.
The corresponding stopping means that is provided with restriction rocker piece amplitude of fluctuation with the drive end of rocker piece 10 on the limiting bracket 9, this stopping means is that screw thread is installed in the stop screw 7 on the limiting bracket.Be provided with elasticity reset device between rocker piece 10 and the stop screw 7.This elasticity reset device comprises spring base 6, spring 5, rocker piece 10 is provided with the blind hole of placing spring 5, spring base 6 covers on the spring 5 for tubbiness, the openend of spring base 6 is arranged in described blind hole, and spring base 6 is slidingly matched with the blind hole inwall, and the other end of spring base 6 contacts with stop screw 7.
Limiting bracket 9 end faces have a plurality of locating pieces 14 by bolting, and each locating piece 14 is provided with the detent that is used for place work piece 17 ends.With each locating piece 14 corresponding oscillating oil cylinder 12 that are provided with, the output of oscillating oil cylinder 12 connects the clamp arm 121 that can be turned to locating piece 14 top workpiece pressings.
Be plugged with positioning sleeve 13 on the sliding shoe 3 vertically and be slidingly connected with sliding shoe, screw 15 is fixed on limiting bracket 9, positioning sleeve 13, base 4 on the main shaft 16.
During clamping workpiece, workpiece 17 two ends are placed in the detent of locating piece 14, the end face of workpiece is close at the bottom of the detent.The primer fluid compressing cylinder promotes trombone slide 1 to left movement, drives sliding shoe 3 by adapter sleeve 2 and is moved to the left.At this moment because cooperating of the projection of inclined-plane and rocker piece 10 drive ends on the sliding shoe 3 makes rocker piece 10 drive ends be lifted, compress spring 5; Rocker piece 10 rotates around fulcrum shaft 8, and the claw 11 of other end connection simultaneously falls clamping work pieces 17.Start oscillating oil cylinder 12 then, the clamp arm of its output rotates on the workpiece end face, workpiece pressing 17.
After machining, leave workpiece 17 by starting oscillating oil cylinder 12 its clamp arms of rotation, hydraulic jack driving trombone slide 1 moves right then, sliding shoe moves right thereupon, the drive end of rocker piece 10 glides along the inclined-plane of sliding shoe 3, rocker piece 10 8 rotations around the shaft under the elastic force effect of spring 5 simultaneously reset, and lift thereby rocker piece is connected with the other end of claw 11, promptly realize unclamping workpiece 17.
When processing different workpiece, can change locating piece 14, claw 11 as required.
Among this embodiment, why adopting trombone slide, is because trombone slide is a hollow, can place the oil pipe of hydraulic oil pump, swing oil pump in its centre bore, and protection oil pipe and outward appearance are clean and tidy.
Because when trombone slide was made, outer surface was a screw thread, inconvenience directly is connected with sliding shoe, so be connected with sliding shoe by adapter sleeve.
The utility model is not limited only to above-mentioned embodiment.
