Abstract
The invention relates to the field of machining, in particular to a main valve hole machining method for a water press distributor valve body. The method comprises the following steps: predrilling, including predrilling a main valve hole in a workpiece with a drill bit until the hole becomes a through hole; reaming, including performing one-step drilling machining of the whole deep hole with a matching drill bit by taking the smallest hole of the main valve hole as a reference; and reaming, including roughly boring the whole supported hole with a cutter rod until the hole has a machining allowance 3 mm to a required dimension, wherein machining is performed in sequence by taking the smallest hole as a reference since the supported valve hole is a stepped hole and tool setting is performed at a remote hole opening end surface, tool feeding and tool setting are performed on the front side of a machine tool spindle during boring, and the hole is machined by virtue of the positioning accuracy of a numerical control machine tool. The method is simple in machining process, facilitates manufacturing, can ensure the machining quality and dimensional precision of the workpiece, reduces the production cost and improves the production efficiency and the economic benefit.
Description
Technical field
The present invention relates to field of machining, be specifically related to the main valve hole processing method of hydraulic press distributor valve body.
Background technology
Hydraulic press needs to carry out large repairs at set intervals, and some parts need be changed, and main allocated equipment valve body is the critical piece needing to change, the hole of this valve body is a lot, has main valve hole, inclined hole, oilhole etc., complex structure, all stepped holes, mutually through between each hole.Particularly main valve hole, the in-built standard component spool of main valve hole.Main valve hole requires that concentricity is less than 0.05mm, difficulty of processing is large, its dimensional accuracy, positional precision, form accuracy directly affects the control accuracy of whole equipment, the technological difficulties of main valve hole processing are: orifice end bore dia is little, aperture remote stomidium diameter is large, adding man-hour cannot directly from orifice end tool setting, bottom end surface, proximal end base end face, the main valve hole degree of depth, concentricity requirement is less than 0.05mm, if utilize the hole boring cutter rod that common boring machine is equipped with, this Geometrical Tolerance Principle cannot be reached at all, often there is stepped hole decentraction, the spool through grinding cannot be assembled, and production efficiency is low.
Summary of the invention
In order to solve the problem, the invention provides a kind of process simple, be easy to manufacture, and crudy and the dimensional accuracy of workpiece can be ensured, reducing production cost, enhance productivity and the main valve hole processing method of hydraulic press distributor valve body of economic benefit.
The main valve hole processing method of hydraulic press distributor valve body of the present invention, comprises the following steps:
The first step, preboring, carries out preboring with drill bit to the main valve hole on workpiece, is drilled to through hole;
Second step, reaming, for referencial use with the minimum aperture on this main valve hole, with the drill bit matched, the drilling of whole deep hole is processed;
3rd step, reaming, require that size stays the allowance of 3mm with the whole support hole of knife bar heavy boring to distance, because support valve opening is stepped hole, and tool setting is at distal port end face, so must process so that minimum aperture is for referencial use successively, during bore hole, from machine tool chief axis front upper slitter, tool setting, utilize the Position location accuracy of Digit Control Machine Tool, process this hole;
4th step, bore hole, with knife bar boring two, place is lateral opening, first, in orifice end tool setting, now with the bore dia tool setting of aperture place, the positioning precision of Digit Control Machine Tool can only be utilized, along z-axis negative direction, boring bar is put in valve opening, be parked according to the pre-set position of drawing, then according to a pre-set bias, with facing head feed bore hole to requiring size, secondly, utilize the positioning precision of Digit Control Machine Tool, control the depth of cut of each bore hole, then sharpening cutter boring root is to requiring size, near-end bottom surface, hole adopts draws boring to process, and method is the same;
5th step, roughing remains each hole, the remaining each hole of above-mentioned steps roughing, diameter allowance 2mm, and carries out abundant natrual ageing;
6th step, fine finishining, uses vibration resistant cutter bar and the cutter hub supporting with it, blade carries out fine finishining to tolerance, hole that concentricity requirement is high, add man-hour, point 3 ~ 4 feeds;
7th step, processing metric thread.
Process of the present invention is simple, is easy to manufacture, and can ensure crudy and the dimensional accuracy of workpiece, reduces production cost, enhances productivity and economic benefit.
