Abstract
The invention provides a method for completing high-precision machining of a valve body hole series on a machine tool of a machining center. The method comprises the following steps: milling is firstly completed; then a valve body is clamped on the machine tool of the machining center; after the valve body is drilled, expanded, bored and reamed, a rough honing knife, a semi-microhoning knife and a microhoning knife are mounted on the machine tool of the machining center; and vertical honing is completed through once clamping. The method has the advantages that a vertical honing machine is cancelled, and vertical honing is completed on the machining center, so the steps of drilling, expansion, boring, reaming and vertical honing can be completed only through once clamping; since the valve body only needs to be positioned once, the machining precision is greatly improved, the machining time is reduced at the same time, the input cost of equipment is lowered, the production efficiency is improved, the valve hole machining precision is improved by multiple grades, and the valve body is matched with a valve core and can be completely interchanged with the valve core.
Description
Technical field
The present invention relates to the processing method of the hole system of the valve body of control element in a kind of hydraulic system.
Background technology
In hydraulic system as the hydraulic valve of control element; Mainly form by parts such as valve body, spool, valve seat, valve gaps; This control element is mainly realized through the relative motion between valve body and the spool the control of pressure, flow and the direction of fluid; Rely on high accuracy fit clearance between the two to satisfy the control requirement, the high accuracy deep hole machining that therefore guarantees valve body hole system is the most important thing of valve element processing.Along with development of high-tech; The shared proportion of hydraulic control technology is increasing; The heavy machinery of tradition is progressively replaced by hydraulic machinery institute; And this substituted process depends on the process technology of hydraulic part key position to a great extent, processing precision direct influence performance of products, life-span and the use of the valve opening of hydraulic valve.
At present; Traditional valve body hole is that the processing technology scheme is: mill-bore-expand-boring-hinge-stand the top gem of a girdle-pendant; Wherein: on plain-milling machine, accomplish usually and mill processing, brill-expansion-boring-hinge is then accomplished at engine lathe or machining center, and the upright top gem of a girdle-pendant is then accomplished on vertical honing machine.Because valve body is heavier, should not repeatedly carry, more unfavorable is in the whole machining process process, to need repeatedly resetting; Influenced machining accuracy, made the dimensional accuracy in hole can only reach 0.02mm, geometric accuracy 0.003～0.005mm; Surface smoothness Ra0.8～Ra0.4; Have a strong impact on the control performance of hydraulic valve, and prolonged process time, increased input cost.
Summary of the invention
The purpose of this invention is to provide a kind of processing method that improves dimensional accuracy, geometric accuracy and the surface smoothness of valve body hole system.
In order to achieve the above object, technical scheme of the present invention has provided and accomplished valve body hole on a kind of work in-process scheming bed is the method for high-precision processing, and step is:
Step 1, on plain-milling machine, accomplish the processing of milling of valve body hole system;
Step 2, the valve body that processing is milled in completion are installed on the lathe of machining center; Bore, expand processing, remove most of allowance and look for straight valve opening, carry out Application of Mechanical Clamping Rigid Boring subsequently, cut with scissors roughness and linearity with further raising valve opening; Stable dimensions is characterized in that:
Rough honing cutter, half microhoning cutter and microhoning cutter are installed on the lathe of step 3, the work in-process heart;
Step 4, confirm the honing total allowance according to the thick fine finishining precision of preceding one deep hole; Adopt rough honing cutter, half microhoning cutter and microhoning cutter that valve body hole system is carried out the thick top gem of a girdle-pendant, the half smart top gem of a girdle-pendant and the smart top gem of a girdle-pendant subsequently successively; Perhaps adopt two varigrained honing cuttves that valve body hole system is carried out the thick top gem of a girdle-pendant and the smart top gem of a girdle-pendant successively, guarantee that the allowance of the smart top gem of a girdle-pendant is not more than 0.005mm.
The present invention has cancelled vertical honing machine, and work in-process is accomplished the upright top gem of a girdle-pendant in the heart, makes brill-expansion-boring-hinge-upright these several steps of the top gem of a girdle-pendant can accomplish through once clamping just; Because only need one-time positioning, thus machining accuracy improved greatly, simultaneously; Reduce process time, reduced the input cost of equipment, improved production efficiency; Make the valve opening machining accuracy improve several grades, valve body cooperates with spool can be realized exchanging fully.
The specific embodiment
For making the present invention more obviously understandable, elaborate as follows with a preferred embodiment now.
Accomplishing valve body hole on a kind of work in-process scheming bed provided by the invention is the method for high-precision processing, and step is:
Step 1, on plain-milling machine, accomplish the processing of milling of valve body hole system;
Step 2, the valve body that processing is milled in completion are installed on the lathe of machining center, bore, expand processing, remove most of allowance and look for straight valve opening, carry out Application of Mechanical Clamping Rigid Boring, hinge roughness and the linearity with further raising valve opening subsequently, stable dimensions;
Rough honing cutter, half microhoning cutter and microhoning cutter are installed on the lathe of step 3, the work in-process heart, and the granularity of rough honing cutter, half microhoning cutter and microhoning cutter is respectively 180～240 orders, 240～320 orders and 320～400 orders;
Step 4, confirm the honing total allowance according to the thick fine finishining precision of preceding one deep hole.For example, when the machining accuracy in current one work step hole was the IT7 level, the honing total allowance should guarantee at 0.04～0.06mm, adopts this moment rough honing cutter, half microhoning cutter and microhoning cutter that valve body hole system is carried out the thick top gem of a girdle-pendant, the half smart top gem of a girdle-pendant and the smart top gem of a girdle-pendant successively.When if the machining accuracy in preceding one work step hole is the IT6 level; The honing total allowance should guarantee at 0.02～0.0mm; Adopt this moment half microhoning cutter and microhoning cutter that valve body hole system is carried out the thick top gem of a girdle-pendant and the smart top gem of a girdle-pendant successively; The allowance of the thick top gem of a girdle-pendant, the half smart top gem of a girdle-pendant and the smart top gem of a girdle-pendant is respectively 0.01～0.03mm, 0.007～0.015mm and 0.0025～0.005mm, guarantees that the allowance of the smart top gem of a girdle-pendant is not more than 0.005mm.
Hole dimension precision through method processing provided by the invention can reach 0.005mm; Geometric accuracy 0.001～0.003mm, surface smoothness Ra0.1～Ra0.2, size reaches unanimity basically; The tolerance decentralization is very little, helps realizing the interchangeability of assembling and enhancing productivity.
