Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model one step is illustrated:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the left view of the utility model embodiment Fig. 1;
In figure: 1 clamps driving oil cylinder, 2 cover plates, 3 the axis of the pistons, 31 left side limited steps, 32 right side limited steps, 4 ring flanges, 5 cylinder bodies, 6 pull bars, 7 casings, 8 oild chucks, 9 axis of guides, 10 claws, 11 cylinder pedestals, 12 pins, 13 pins.
The specific embodiment
As shown in Figure 1, 2, this multiple purpose machine fixture, clamp driving oil cylinder 1, pull bar 6, oild chuck 8, claw 10 existing comprising; Also comprise the casing 7 that drives oil cylinder 1, oild chuck 8 to be connected with described clamping.The special feature of this fixture is: in its casing 7, be provided with displacement drive oil cylinder; Displacement drive oil cylinder comprises cylinder body 5, the axis of the piston 3, ring flange 4; Described cylinder body 5 is arranged on a cylinder pedestal 11; Ring flange 4 is fixed in one end of cylinder body 5; The left end of the axis of the piston 3 stretches out rear connection one cover plate 2 of ring flange 4, and this cover plate 2 is affixed with casing 7; The right-hand member of the axis of the piston 3 is connected with casing 7 after stretching out cylinder body 5; These the axis of the piston 3 axial location between cover plate 2 and casing 7; Between the ring flange 4 and cover plate 2 of described displacement drive oil cylinder, be provided with removable spacing between cylinder body 5 and the left surface of casing 7.
The further technical scheme that the present embodiment adopts: be provided with left side limited step 31 corresponding to the right flank of cover plate 2 on the left end of described the axis of the piston 3; On the right-hand member of the axis of the piston 3 with the corresponding right side limited step 32 that is provided with of left surface of casing 7; Can realize like this axis of the piston and move axially drive case 7 then and move axially along the axis of guide 9, and limit cylinder body 5 and move axially; And simple in structure, easily assemble and safeguard.
Certainly the structure that realizes the axis of the piston 3 drive case 7 has multiple, also can adopt the fixing mode of connector.But structure certainly will be than the mode complexity of limited step.Therefore the mode of preferred limited step.
The further technical scheme that the present embodiment adopts: one through hole is set in cylinder body 5 bottoms, this through hole is parallel with the axis of the piston 3, an axis of guide 9 parallel with the axis of the piston 3 is assemblied in this through hole and movement that can be axial, one end of the axis of guide 9 is plugged on cover plate 2 and along the pin 12 of radially using of the axis of guide 9 and fixes, and it is also radially fixing with pin 13 along the axis of guide 9 that the axis of guide 9 other ends are plugged on casing 7.The axis of guide is set, can improves mobile reliability, improve serviceability.Pin 12,13 can prevent that the axis of guide 9 from rotating, and further improves the reliability of this fixture.
When use, cylinder pedestal 11 is fixed on platen or tail stock base plate.
When work, hydraulic oil enters cylinder body 5 inner chambers of displacement drive oil cylinder, promotes the axis of the piston 3 axially-movables.While needing clamping work pieces, driven plunger axle 3 moves right, and promotes casing 7 move to right together by its right side limited step 32.In the time moving to correct position, clamp and drive oil cylinder 1 work to drive pull bar 6 to stretch out, control oild chuck 8 and clamp, drive claw 10 tensioners (clamping) workpiece.
After machining, clamp and drive oil cylinder 1 to unclamp workpiece by pull bar 6, oild chuck 8, drive claw 10.Then hydraulic oil enters the inner chamber of displacement drive oil cylinder, the axis of the piston 3 moves to left, and promote cover plate 2 by its left side limited step 31, and cover plate 2 drives casing 7 and is arranged on clamping on casing 7 and drives oil cylinder 1, oild chuck 8, claw 10 to move to left together, and claw 10 exits workpiece.
This fixture can solve similar automobile axle clamping deformation large, locate the clamping orientation problem on insecure heteromorpha part work in-process heart class lathe, easy to operate, part accurate positioning is reliable, good processing accuracy, percent defective is low.Can also be used in the function that realizes the second secondary main shaft on lathe, processing cart, bore compound part, realize one-machine-multi-function, save the turnaround time.This fixture versatility is good, easily adjusts, and greatly reduces special fixture and equipment investment, economizes on the use of funds, and the reduction product turnaround time, has greatly improved production efficiency.
" left side " in the utility model, " right side " are only the relative positions adopting for convenience of description, do not represent absolute positional relation.
