Abstract
Disclosed is a mechanical self-locking type pneumatic clamping mechanism used on a jig of a machine tool, which fastens the workpiece with poor rigidity on the jig reliably under the condition of nonflexible workpiece. The mechanism is a hydraulic piston cylinder in the vertical direction and is an air pressure piston cylinder in the horizontal direction, the upper end of the hydraulic piston rod is connected with a pressing plate, and the inclined plane at the lower end of the hydraulic piston rod contacts with the upper surface of a movable pin on the inclined plane at the middle part of the air pressure piston rod. After the hydraulic cylinder piston rod clamps the workpiece by moving upwards, the pneumatic cylinder piston rod is started to do the horizontal movement, and the movable pin surface in the middle inclined plane of the piston rod is adjusted automatically for contacting with the inclined plane of the lower end of the hydraulic rod, so as to form the self locking for unloading the pressure and keep the workpiece in the reliable fastening state.
Description
Affiliated technical field
The utility model relates to a kind of mechanical self-latching type pneumatic pinch mechanism that uses on jig, especially can reach under the indeformable situation of workpiece the relatively poor part of rigidity, and workpiece is fastened on the anchor clamps reliably.
Background technology
In the part of machine tooling, anchor clamps generally adopt methods such as mechanical type clamping, fluid pressure type clamping and pneumatic type clamping, are very easy to make part to produce distortion when the relatively poor part of rigidity is clamped, and influence the machining accuracy of part.
Summary of the invention
In order to overcome when the relatively poor part of processing rigidity, because of the distortion that clamping causes, the utility model provides a kind of mechanical self-latching type pneumatic pinch mechanism, during the relatively poor part of this mechanism's clamping rigidity, can reach under the indeformable situation of workpiece, obtain fastening reliably.
The technical scheme that its technical problem that solves the utility model adopts is: after adopting the hydraulic clamp workpiece, by release behind the airbrasive self-locking workpiece.Liquid presses piston pole moves up and down, and the piston rod upper end is connected with pressing plate, the lower end is an inclined-plane.The horizontal movement of pneumaticpiston bar, there is an inclined-plane piston rod middle part.Behind the up clamping work pieces of liquid presses piston pole, start the horizontal movement of pneumaticpiston bar, the plane on the removable pin in the inclined-plane, pneumaticpiston bar middle part sheds pressure after contacting with the inclined-plane of liquid presses piston pole lower end and forming self-locking.This moment, workpiece kept tightening state under the self-locking of pneumaticpiston bar and liquid presses piston pole, and made workpiece not produce distortion.
The beneficial effects of the utility model are: when the relatively poor part of processing rigidity, guarantee can make workpiece fastening reliably under the indeformable situation of clamping work pieces, effectively guaranteed the machining accuracy of part.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing is a mechanical self-latching type pneumatic pinch mechanism structure schematic diagram, is illustrated as the clamping self-locking state.1. pneumatic cylinder piston rods among the figure, 2. removable pin, 3. hydraulic cylinder piston rod, 4. pressing plate, 5. support, 6. compacted part.
The specific embodiment
Vertical direction is a hydraulic cylinder among the figure, and horizontal direction is a pneumatic cylinder.Liquid presses piston pole (3) rises by hydraulic pressure and promotes pressing plate (4), behind support (5) workpiece pressing (6), the inclined-plane contacted with the inclined-plane of liquid presses piston pole (3) lower end in the middle of pneumaticpiston bar (1) made it by the air pressure left lateral, go up the adjustment on plane by removable pin (2), shed hydraulic pressure after making two self-locking inclined-planes form self-locking.Guaranteed to make workpiece fastening reliably under the indeformable situation of clamping work pieces.
Claims (2)
1. mechanical self-latching type pneumatic pinch mechanism, the liquid presses piston pole upper end joins with pressing plate, the plane contacts on the removable pin on the inclined-plane of liquid presses piston pole lower end and the inclined-plane, horizontal air pressure piston rod middle part, and it is characterized in that: the removable pin plane on the pneumaticpiston bar inclined-plane contacts with the inclined-plane of liquid presses piston pole lower end.
2. mechanical self-latching type pneumatic pinch according to claim 1 mechanism, it is characterized in that: this mechanism is hydraulic piston cylinder in vertical direction, is the pneumaticpiston cylinder on the horizontal direction.
