Description
Technical field
The utility model relates to a kind of clamping device of machined piece, relates in particular to a kind of centering clamping device.
Background technology
During the ladder frame of bull-dozer industry in the machine table vehicle frame, need to be take the ladder frame center line of bogie frame as benchmark.The bogie frame volume is large, heavy, and centering, clamping are difficult for finishing.In order to guarantee machining accuracy, boost productivity, must be fixed on workpiece the tram of lathe, need with setting element workpiece to be positioned.At present, the location of the part of the ladder frame in the bogie frame and clamping generally all are to utilize driving or other aids to carry out by the workman.Location, clamping process expend the more time, owing to workpiece is comparatively grown up, when adjusting, can not look after simultaneously all around of part, adjust inconvenience, leveling one side, another side perk, need to repeatedly adjust, locate very difficultly, the situation that location clamping time far surpasses process time usually occurs, have a strong impact on working (machining) efficiency, particularly for the processing of ladder frame locating piece, the efficient of location, clamping seems particularly important to the impact of working (machining) efficiency.
The utility model content
Technical problem to be solved in the utility model is: a kind of centering clamping device is provided, and the realization workpiece is located fast, is clamped, and reduces centering, clamping time, enhances productivity.
The utility model is that the technical scheme that the problem of the above-mentioned proposition of solution adopts is:
A kind of centering clamping device, comprise base 1, hinge seat 2, hinge 3, clamp 4, slideway 5, slide block 6 and drive unit 7, hinge seat 2 and slideway 5 are fixed on the base 1, hinge seat 2 is connected with clamp 4 by hinge 3, slide block 6 is installed in the guide groove of slideway 5, and slide block 6 upper ends are connected with clamp 4, and slide block 6 lower ends are connected with drive unit 7.
Described base 1 bottom arranges moving positioning device.
Described hinge seat 2 and slideway 5 are fixed by screws on the base 1.
Described slide block 6 upper ends and clamp 4 are connected by straight pin.
Described slideway 5 is linearity slideway or circular-arc slideway.
Described slide block 6 is linearity slide block or circular-arc slide block.
Described drive unit 7 is fluid pressure drive device or mechanical actuation device.
Operation principle of the present utility model: base is fixed on the workbench, and when needing to clamp, hydraulic cylinder upwards ejects, promoting slide block moves upward along slideway, the motion of slide block drives two clamps separately around hinge through, and outwards rotate on the top of clamp, the tensioner action of implement device; In the time of need to unclamping, hydraulic cylinder retracts downwards, and the band movable slider moves downward along slideway, and the motion of slide block drives two clamps separately around hinge through, and inwardly rotate on the top of clamp, the lax action of implement device.
The beneficial effects of the utility model are: 1, convenient to use, reduce labour intensity; 2, automaticity is high, and flexibility is good, reliable clamping; 3, adjustable range is large, applicable to the different size workpiece.
