Description
Technical field
The present invention relates to the technical field of numerically controlled lathe clamping tool, especially relate to a kind of hydraulic power fixture.
Background technology
At present, the fixture being usually used in numerically controlled lathe clamping cuboid part and out-of-shape part mostly is chuck, floral disc and bent plate, and structure is comparatively simple, has become the common cognition in industry.First this installation way needs the table process of beating by dial gauge is loaded down with trivial details to carry out centering part, then compresses with pressing plate, then carries out boring, car, the processing content such as to attack.Single-piece or small lot batch manufacture, this installation way generally uses.Its centering is loaded down with trivial details, clamping is not firm, rotary centrifugal force is comparatively large, handling and centering part inefficiency.Brill, car, to attack etc. locate in process not firm, part may occur swinging or follow the direction of rotation of boring or tapping to rotate, cause boring or tapping influenced, the defect rate of processing generally can be caused high, drill bit even can be caused to interrupt or drawn askew sign, in the environment of High-speed machining, easily damage is caused to parts such as spindle of numerical control lathe, bring huge economic loss to enterprise.Usually at clamping with when dismantling the part processed, expend time in and energy, need manually the screw of pressing plate to be unscrewed, dismantle clamping, the efficiency making work also very under.Board for different size needs the different mount pad of customization and pressing plate especially, which adds the economy expenditure of enterprise, and the waste degree of material is also large, and precision is also extremely low simultaneously, and during machining sheet part, the degree of error of each board is high.
Summary of the invention
For the deficiency that above-mentioned prior art exists, the object of this invention is to provide a kind of stability that can ensure to process, can quick-clamping, the degree of accuracy of clamping is also very high, makes the hydraulic power fixture that working (machining) efficiency and precision also increase.
For realizing above-mentioned object, the invention provides following technical scheme:
A kind of hydraulic power fixture, comprise mount pad, side on described mount pad is provided with bent plate, side perpendicular with mount pad on bent plate is interval with removable two back-up blocks be parallel to each other, bent plate between two back-up blocks is provided with several bolt fixing hole, wherein two bolt fixing hole is inserted with alignment pin; Side relative with bent plate on described mount pad is fixed with hinged seat, hinged seat is hinged with linking arm, the other end end of linking arm is hinged with and coordinates the crushing block that can clamp workpiece to be added with two back-up blocks, described mount pad is provided with pilot hole between hinged seat and bent plate, the axis of guide driven by power set is slidably equipped with in pilot hole, the axis of guide is fixed with fixed support, and the middle part of described linking arm is connected by jockey with fixed support.
The present invention is set to further: the concrete structure that middle part and the fixed support of described linking arm are connected by jockey is: fixed support is hinged with articulated jib, and the other end of articulated jib is articulated with the middle part of linking arm.
The present invention is set to further: the concrete structure that middle part and the fixed support of described linking arm are connected by jockey is: the middle part of linking arm offers bar hole along the axis of linking arm, support bracket fastened end is provided with the yoke with jointed shaft, yoke by jointed shaft through bar hole and linking arm hinged.
The present invention is set to further: the both sides described mount pad being positioned at hinged seat are respectively equipped with balancing weight.
The present invention is set to further: described two back-up blocks are installed on bent plate by screw fastening.
By adopting technique scheme, the technique effect that the present invention reaches is: by arranging back-up block on mount pad, the crushing block driven by power set and back-up block match and carry out coordinating the board clamping and be placed on two back-up blocks, add two alignment pins of setting, this fixture is made well to form the positioning and clamping pattern of plane and two pits when clamping, not only can ensure the stability of processing, and can quick-clamping, the degree of accuracy of Set and Positioning is also very high, working (machining) efficiency and precision are improved a lot, the yield rate of the product of processing is also high, and clamping and dismounting board time, only need manually board to be placed on the back-up block of bent plate, control power set and drive axis of guide motion, make between the fixed support of the axis of guide and linking arm, to form crank block motion, drive and extrude fast and back-up block compression board, clamping is high with dismounting effect, be applicable to the board of sizes, decrease the economy expenditure that manufacturer is meaningless.
