Embodiment Construction

[0014] The left support seat 3 and the right support seat 2 are respectively at the two ends of the milling machine table, and the workpiece 9 is placed between the two support seats;

[0015] The left supporting seat 3 is threadedly connected with the screw rod 5, and is fixed on the machine tool workbench 1 through the screw rod 5, and a left thimble 4 is movably connected in the middle cavity, which is pushed in the left positioning hole of the workpiece 9;

[0016] The upper end of the screw rod 5 is threadedly connected with a connecting plate 7, and the front end of the connecting plate 7 is connected with a pressing plate 8. After the workpiece 9 is positioned, the nut 6 can be tightened to compress the workpiece 9;

[0017] The right thimble 10 is arranged in the middle through hole of the right bearing seat 2, pushes against the right positioning hole of the workpiece 9, and is movably connected with the connecting rod 13 through the middle through hole; a spring 11 is...

Abstract

The invention discloses a cone locating and milling clamp for a valve body. The two sides of a work piece are located by a centre; a set screw is used to adjust, locate and lock the work piece; a pressure plate is used to press the work piece; and in this way, the work piece of the valve body is clamped conveniently and rapidly. Furthermore, the conical head part of the centre is designed as a cone; the centre is symmetrically provided with tangent plane bodies by milling from a small end to a large end along the direction of conical degree; and when the centre is pushed into locating holes at the two sides of the work piece, a gap is formed in the vertical direction, so that the height of the work piece can be adjusted conveniently, and the work piece can be located accurately. The cone locating and milling clamp for the valve body disclosed by the invention is reasonable in structural design, convenient and rapid to operate, and stable and reliable to clamp; and the two machined surfaces of the work piece meet the technical requirements such as symmetry, thus effectively ensuring the machining quality of the work piece.

Description

technical field [0001] The invention relates to a tooling facility, in particular to a valve body cone positioning milling fixture. Background technique [0002] A valve is a common hydraulic part, and its body surface is usually machined on a milling machine. Due to the fact that some valve body workpieces have long shapes, large volumes, and irregular shapes, if a conventional fixture for positioning and clamping one end of the valve body is used, when milling the processing plane, the workpiece is often not clamped tightly and the machining The time-diameter surface jumps, and the two planes are not symmetrical about the center. Contents of the invention [0003] The technical problem to be solved by the present invention is to improve the existing milling and clamping device to provide a valve body cone positioning milling fixture with reliable positioning, firm clamping and guaranteed processing quality. [0004] The present invention is realized through the follow...
