Abstract
The utility model provides a valve core end face milling clamp which is simple in structure, convenient to use and capable of improving machining efficiency. A valve core comprises a valve plate and two core shafts, wherein the core shafts are arranged on two sides of the valve plate. The valve core end face milling clamp comprises a compound die composed of two half dies, the compound die is provided with a valve plate hole formed by semi-circular holes in the two half dies, and two sides of the valve plate hole are respectively provided with a core shaft hole, wherein the axial line of the core shaft hole is perpendicular to the axial line of a circular hole, and the core shaft hole is formed by semi-circles on the two half dies. A rotation prevention column is arranged in the valve plate hole. One of the half dies is connected with a movable jaw of a jaw vice, and the other half die is connected with a fixed jaw of the jaw vice.
Description
Technical field
Present technique relates to clamp for milling end surfaces, specifically, is the spool end milling fixture.
Background technology
Referring to Fig. 1,2, spool 1 comprises valve plate 11 and is positioned at two mandrels 12,13 of valve plate both sides.For the end face to mandrel carries out milling, because valve core structure is more special, be difficult to location and clamping.
Summary of the invention
The purpose of present technique provides a kind of simple in structure, easy to use, spool end milling fixture that can improve working (machining) efficiency.
This spool end milling fixture, described spool comprises valve plate and is positioned at two mandrels of valve plate both sides, the spool end milling fixture comprises a matched moulds that is comprised of two half modules, described matched moulds has a valve plate hole that is comprised of two first circular holes of half module, in the both sides in valve plate hole a core axle hole that axis is vertical with described round hole axial is arranged respectively, core axle hole is comprised of two half module upper semi-circles; Be provided with anti-rotary column in the valve plate hole; A half module links to each other with the moving jaw of vice, and another half module links to each other with the regular jaw of vice.
The beneficial effect of present technique: during use, two mandrels of spool are placed in the core axle hole on the matched moulds and position, the valve plate of spool is positioned at the valve plate hole of matched moulds simultaneously, anti-rotary column has prevented the rotation of valve plate, by the clamping of vice to matched moulds, spool is clamped, can carry out milling to end face of mandrel.These anchor clamps are reliable to the spool location, use existing vice, and cost is low, and is easy to operate, and working (machining) efficiency is high.
Above-mentioned spool end milling fixture, two and half mode structures are identical.
Above-mentioned spool end milling fixture, the end face of anti-rotary column are the cambered surfaces high in the middle of, that periphery is low.
