Abstract
The utility model discloses a valve cone positioning milling fixture which positions through centers on two sides of a workpiece, adjusts, positions and locks through a fastening screw, and tightly presses through a pressing plate, and achieves the clamping operation of a valve workpiece conveniently and rapidly. Furthermore, a cone head portion of each centre is designed into a conoid, tangent plane bodies are symmetrically arranged along the conical degree direction from a small end to a big end in a milling mode, after the tangent plane bodies eject into positioning holes one two sides of the workpiece, a gap is formed in the perpendicular direction, the height of the workpiece can be adjusted conveniently, and positioning of the workpiece can be accurate. The valve cone positioning milling fixture is reasonable in structural design, the operation is convenient and fast, clamping is stable and reliable, two machining faces of the workpiece accord with technical requirements of degree of symmetry and the like, and machining quality of the workpiece is effectively ensured.
Description
Technical field
The utility model relates to a kind of frock facility, is specifically related to a kind of valve body cone location milling clamper.
Background technology
Valve is a kind of common hydraulic part, and its valve body surface is processed at milling machine usually.Because the valve body workpiece profile that has is longer, volume is larger, and the workpiece profile is irregular, if adopt the conventional anchor clamps that valve body one end is positioned and clamps, when milling processing plane, often exist workpiece clamp tight, add man-hour diametric plane beat, two planes are with problems such as Central Symmetries.
Summary of the invention
The technical problems to be solved in the utility model is that existing mill clamping device is improved, and a kind of reliable, as to clamp firmly, guarantee crudy a kind of valve body cone location milling clamper of locating is provided.
The utility model is achieved through the following technical solutions:
A kind of valve body cone location milling clamper at the milling machine table two ends, is fixed with respectively left supporting base and right supporting base, and workpiece places between two supporting bases; Left supporting base is fixed on the platen by screw rod, wherein is connected with left thimble in the cavities, withstands in the left positioner hole of workpiece; Pressing plate is movably connected on the screw rod upper end by connecting plate, screws nut behind the workpiece location and compresses; Right thimble is located in the intermediate throughholes of right supporting base, withstands in the right positioner hole of workpiece, and passes intermediate throughholes and connecting rod flexible connection; Step place at right thimble is provided with spring, and backing plate withstands spring by bolt right thimble is compressed, fixes; Connecting rod is fixedly connected with holding screw, withstands right supporting base end face, and right thimble is regulated, located and locks.
The further improvement project of the utility model is that the cone head part of described left and right thimble is divided into cone, and is milled with tangent plane body to large end along the taper direction symmetry from small end.
The utility model further improvement project is that the tangent plane body of described left and right thimble is four, and distributes take symmetry axis as the axle center axial symmetry.
The utility model compared with prior art, have following obvious advantage: the utility model is by locating with thimble in the workpiece both sides, regulate, locate and lock by holding screw, and compress by pressing plate, realize quickly and easily the clamp operation of valve body workpiece, reliable and stable, meet the specification requirements such as symmetry of the relative central shaft of two machined surfaces, guarantee crudy.Further, the thimble cone head part divides and is designed to cone, and is milled with tangent plane body to large end along the taper direction symmetry from small end, behind the locating hole that heads into the workpiece both sides, form in the vertical direction the gap, be convenient to workpiece adjustment height, so that the workpiece location is more accurate, guarantee the workpiece crudy.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the plan structure schematic diagram of Fig. 1.
Fig. 3 is the structural representation of left and right thimble part conehead part of the present utility model.
Fig. 4 is the side-looking structural representation of Fig. 3.
The specific embodiment
A kind of valve body cone location milling clamper, with reference to Fig. 1,2, wherein:
Left supporting base 3 and right supporting base 2 are respectively at the milling machine table two ends, and workpiece 9 places between two supporting bases;
Left supporting base 3 is threaded with screw rod 5, and is fixed on the platen 1 by screw rod 5, wherein is connected with left thimble 4 in the cavities, withstands in the left positioner hole of workpiece 9;
The screw rod 5 upper ends connecting plate 7 that has been threaded, connecting plate 7 front ends are connected with again pressing plate 8, can screw 6 pairs of workpiece 9 of nut behind workpiece 9 location and compress;
Right thimble 10 is located in the intermediate throughholes of right supporting base 2, withstands in the right positioner hole of workpiece 9, and passes intermediate throughholes and connecting rod 13 flexible connections; Step place at right thimble 10 is provided with spring 11, and backing plate 12 withstands 11 pairs of right thimbles 10 of spring by bolt and compresses, fixes; Connecting rod 13 is fixedly connected with holding screw 14, withstands right supporting base 2 end faces, and right thimble 10 is regulated, located and locks.
Referring to Fig. 3,4, structural representation for left and right thimble 4 of the present utility model, 10 conehead part, as seen from the figure, left and right thimble 4,10 conehead are cone, and be milled with tangent plane body 4-1,10-1 from small end to large end along the taper direction symmetry, quantity is four, and distributes take symmetry axis as the axle center axial symmetry.Left and right thimble 4,10 respectively with tangent plane body 4-1, head into when 10-1 is upper-lower position in the locating hole of workpiece 9, gapped because of vertical direction, so workpiece 9 can be regulated on the vertical height, guarantee that the location is more accurate.
The utility model reasonable in design, convenient to operation, clamp reliable and stable, thereby make front and back two machined surfaces of workpiece 9 meet the specification requirements such as symmetry, guarantee crudy.
