Abstract
The invention relates to a valve body machining method, in particular to a valve body machining method for an oil cooler. The method is used for solving the problem that the machining accuracy of a taper hole in a valve body cannot be ensured by the conventional valve body machining method for the oil cooler. The method comprises the following steps of turning an auxiliary support ring on the valve body by using a vertical lathe, wherein the auxiliary support ring has a diameter of 440mm; roughly turning and finely turning an inner tapered hole and each stepped hole in the valve body by using a horizontal numerical control lathe; turning off the auxiliary support ring of the valve body by using the vertical lathe, and smoothening an end face in a turning way; machining an oil through hole and each threaded hole in the valve body by using a boring lathe; facing up the machined valve body and the outer circular conical surface of a valve element to implement the whole machining process. The method is used for machining the valve body of the oil cooler.
Description
Technical field
The present invention relates to a kind of valve body processing method, be specifically related to a kind of oil cooler valve body processing method.
Background technology
Valve body is a kind of vitals of Oil Cooler of Steam Turbine with six-way valve, during work, the taper hole of valve body matches, is sealed with the outer conical surface of spool, the taper hole required precision of these parts is higher, require cylindricity 0.03mm, these parts are cast blank, and profile is non-rotating profile profile, difficulty of processing is high, and existing processing method can not guarantee the machining accuracy of taper hole.
Summary of the invention
The present invention can not guarantee the problem of the machining accuracy of valve body taper hole for solving existing oil cooler by the valve body processing method, and then proposes a kind of oil cooler valve body processing method.
The present invention addresses the above problem the technical scheme of taking to be: the concrete steps of the method for the invention are as follows:
Step 1, on boring machine processing valve body datum level: five faces of the non-arc surface of processing valve body guarantee that each face depth of parallelism and perpendicularity are 0.02, the supplemental support ring that to leave width on the valve body axial length be 40mm;
Step 2, use vertical lathe turning supplemental support ring on valve body, the diameter of supplemental support ring is 440mm;
Step 3, utilize horizontal NC lathe to carry out rough turn, finish turning tapering internal control and each stepped hole to valve body;
Step 4, by vertical lathe, the supplemental support ring turning of valve body is fallen, and the end face car is flat;
Step 5, utilize boring machine to process oil through and each screwed hole on valve body;
Step 6, by the valve body that processes and spool outer conical surface to grinding: lapping mode selects chain block to suspend, adopt the white fused alumina grounds travel, wherein the granularity of white fused alumina grounds travel is 180 orders, spool is ground repeatedly to the required precision that makes the contact-making surface of spool and valve body be greater than 80% with the conical surface that coordinates of valve body;
Step 7, by valve body seamed edge abate, and on valve body franking.
The invention has the beneficial effects as follows: the present invention adopts and leaves the supplemental support ring at the large end of valve body taper hole, utilize center bearing bracket to support the supplemental support ring, not only solved a clamping difficult problem, and also greatly reduced runout in process, improved the crudy of conical surface endoporus, after finish turning valve body taper hole, adopt and the process program of spool to grinding, grind the required precision that the contact-making surface of rear valve body and spool is greater than 80%, improved the machining accuracy of parts, met instructions for use.
