Abstract
The invention discloses a hydraulic clamping device with high reliability, which comprises a movable block, an oscillating rod, a workpiece supporting part, a support frame, a support shaft, an idler wheel, a machine frame and a hydraulic system. A hydraulic cylinder, an electromagnetic valve, a relief valve, a pump and oil cylinders are connected in sequence; the hydraulic clamping device is a fixture which realizes to support and the clamp a workpiece by adopting hydraulic components instead of machinery parts; with the assembly of the hydraulic system and a mechanical part, the hydraulic clamping device can ensure to tightly clamp the workpiece and can reduce the oscillation and the deformation of the workpiece through floating support during the machining; the hydraulic clamping device can not only bear heavy cutting force during rough machining and can but also ensure to perform supporting, clamping and fast pressure release to the workpiece, what a manual fixture can not realize during precision machining.
Description
Technical field
The present invention relates to a kind of highly reliable hydraulic clamp.
Background technology
Clamping device is widely used in various technical process and the plant equipment; For example employed anchor clamps all are common grip devices in clamping mechanism in the injection machine and the mechanical processing process; The clamping force of clamping device normally derives from the fastening force of screw thread; But when the threaded connection place owing to stressedly excessively cause thread to wear and tear making the thread can't interlock; So just, can making is threaded can't tighten, and in some plant equipment of controlling automatically, the fastening force of screw thread has just satisfied not the requirement of robot brain tool.
Summary of the invention
Goal of the invention: the objective of the invention is in order to solve the deficiency of prior art; A kind of highly reliable hydraulic clamp is provided; Can realize to workpiece support, clamping and to the quick release of workpiece pressure, and can reduce vibration and the distortion in the unsteady support process.
Technical scheme: in order to realize above purpose, a kind of highly reliable hydraulic clamp of the present invention, it comprises: movable block, swing arm; Workpiece support section, bracing frame, back shaft, roller; Frame and hydraulic system: hydraulic cylinder, magnetic valve, overflow valve, pump links to each other with oil cylinder successively; The two ends of described frame are respectively equipped with the workpiece support section of movable block and supporting workpiece, and movable block is fixed on the piston rod of hydraulic cylinder, and the middle of support portion and movable block is provided with bracing frame; The back shaft that bracing frame is provided with is fixedly supported on swing arm on the bracing frame, and an end of swing arm is provided with the clamping section, and the other end of swing arm is provided with the roller of cam-like.
Described back shaft and swing arm adopt the fit system of non-interference fit.
Beneficial effect: a kind of highly reliable hydraulic clamp provided by the invention; This hydraulic clamp is through replacing machine components to realize the anchor clamps to the supporting and the clamping of workpiece with Hydraulic Elements; Hydraulic clamp through being assembled together hydraulic system and mechanical part can guarantee the workpiece firm grip; And can support vibration and the distortion that reduces in the processing through floating; This hydraulic clamp can bear big cutting force when roughing, also can guarantee when Precision Machining, to accomplish support, clamping and the quick pressure that discharges workpiece that manual can't be accomplished.
Description of drawings
Fig. 1 is an operation principle sketch map of the present invention.
The specific embodiment
As shown in Figure 1, a kind of highly reliable hydraulic clamp of the present invention, it comprises: movable block 2, swing arm 3; Workpiece support section 4, bracing frame 5, back shaft 6, roller 11; Frame 12 and hydraulic system: hydraulic cylinder 1, magnetic valve 7, overflow valve 8, pump 9 links to each other with oil cylinder 10 successively.
The two ends of frame 12 are respectively equipped with movable block 2 and workpiece support section 4; Movable block 2 is fixed on the piston rod of hydraulic cylinder 1; Be provided with the support portion 4 of workpiece and the middle of movable block 2 and be provided with bracing frame 5; The back shaft 6 that bracing frame 5 is provided with is fixedly supported on swing arm 3 on the bracing frame 5, and an end of swing arm 3 is provided with clamping section 13, and the other end of swing arm 3 is provided with the roller 11 of cam-like.
The fit system of described back shaft 6 and the non-interference fit of swing arm 3 employings.
The overflow valve 8 of when pump 9 pumps fluid from oil cylinder 10 after, flowing through gets in the hydraulic cylinders 1, through the control of magnetic valve 7 through magnetic valve 7; Fluid gets into the oil suction chamber 14 of oil cylinder 1, promotes piston actuated movable block 2 to left movement, because of bracing frame 5 is provided with back shaft 6; The two ends of back shaft 6 are respectively equipped with clamping section 13 and roller 11, are fulcrum with back shaft 6, when movable block 2 is moved to the left; Cam-like roller 11 surfaces that are provided with because of swing arm 3 are curved profile, and its curved profile contacts and props up through the inclined-plane with movable block 2 one sides, thus the workpiece on the control swing arm 3 workpiece pressing support portions 4; And the maintenance self-locking state, after oil was full of whole cylinder 1, overflow valve 8 left greatly; Through release, realize the protection of the pressure of whole hydraulic circuit, make pressure stability in the scope of regulation.When needs discharge the pressure to workpiece, get into out oil pocket 15 by magnetic valve 7 control fluid, move right thereby promote piston actuated movable block 2, the inclined-plane of the curved profile of roller 11 and movable block 2 unclamps, and has realized the quick release of workpiece pressure.
A kind of highly reliable hydraulic clamp provided by the invention is through replacing machine components to realize the anchor clamps to the supporting and the clamping of workpiece with Hydraulic Elements; Hydraulic clamp through being assembled together hydraulic system and mechanical part can guarantee the workpiece firm grip; And can support vibration and the distortion that reduces in the processing through floating; This hydraulic clamp can bear big cutting force when roughing, also can guarantee when Precision Machining, to accomplish support, clamping and the quick pressure that discharges workpiece that manual can't be accomplished.
The above only is a preferred implementation of the present invention; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the principle of the invention, can also make some improvement and retouching, these improvement and retouching also should be regarded as protection of the present invention.
