Abstract
The present invention relates to a kind of processing technology in mozzle locking plate hole outside nuclear power station axle envelope main pump, L-type angle head is coordinated to carry out numerical control programming processing using Five-axis NC Machining Center, using three face sword tool sharpening locking plate holes, it is highly stable during the process processing locking plate hole of the present invention, due to being digital control processing, so that locking plate hole obtains very high position degree and surface roughness, required precision can not be met by solving manual operations, and Digit Control Machine Tool is the problem of can not carry out outer mozzle locking plate hole machined, and the production capacity and economic benefit of enterprise are greatly improved with processing efficiency.
Description
Technical field：The present invention relates to a kind of processing technology in mozzle locking plate hole outside nuclear power station axle envelope main pump.
Background technology：The outer mozzle of nuclear power station axle envelope main pump is one of critical component of nuclear power station axle envelope main pump, outer water conservancy diversion
The processing and manufacturing of pipe is particularly important for the production domesticization of axle envelope core main pump.The locking plate hole machined of outer mozzle is the technology of this workpiece
Problem.The country processes this part beyond example, and the processing method that foreign countries colleague uses is to coordinate frock auxiliary using electric hand drill, its
Defect is the quality unstability that artificial mode is brought, and machining accuracy and roughness are all extremely difficult to design requirement,
Need in later stage assembling process, locking plate matched somebody with somebody according to the one-to-one reality of the situation in locking plate hole, does not reach the basic demand of workpiece interchangeability,
And craft processing efficiency is low, also the efficiency to assembling brings adverse effect.
The content of the invention：The present invention seeks to disclose, a kind of reliability is high, crudy is high, high in machining efficiency and can guarantee that
The processing technology in the outer mozzle locking plate hole of nuclear power station axle envelope main pump of the outer mozzle locking plate hole design requirement of nuclear power station axle envelope main pump.
To achieve the above object, scheme is as follows：A kind of processing technology in the outer mozzle locking plate hole of nuclear power station axle envelope main pump, is added using five axles
Work center coordinates L-type angle head, with reference to three face angle of throat tools, carries out numerical control programming processing, the above method comprises the following steps：
1) it will be fixed on after outer mozzle (1) centering on machining center (3) workbench；
2) L-type angle head (4) is arranged on machining center (3), three face angle of throat tools (5) is arranged on angle head (4)；
3) by drawing size requirement numerical programming procedure, using the cutter track analog functuion of lathe to entering to cutter track track
Row simplation verification；
4) according to the material property of outer mozzle, Tool in Cutting linear velocity and feed engagement are determined, according to formula S=V/
D/ π, wherein S represent cutter rotating speed, and V represents cutter linear velocity, and D represents tool diameter) and F=S × Z × f, F represent that cutter enters
To speed, S represents cutter rotating speed, and Z represents tool blade number, and f represents cutter feed engagement, calculates cutter rotating speed and feeding speed
Degree, is processed using the numerical control program for verifying errorless, first processing left side locking plate half bore (2), then processing right side locking plate half
Hole (2), cutter is exited from hole, and angle head returns to workpiece centre, and workpiece rotates to next locking plate hole site；5) according to step
1) to step 4) processing step process other uniform locking plate holes.
The use numerical control processing technology of the invention, with reference to L-type angle head in three face angle of throat tools, substitutes colleague and uses
Manual processing mode, not only increase processing efficiency so that process time shortens more than 80%, and ensure that processing
The uniformity and precision of effect and the requirement of roughness, improve the quality of product, it is to avoid due to each caused by manual operations
Locking plate hole is inconsistent, it is necessary to reduce installation time, especially to the one-to-one adjustment of locking plate progress according to locking plate hole in assembling process
It is the locking plate hole of this highly versatile when nuclear power station is overhauled, maintainer is shortened in maintenance process the maintenance of radiation
Disassembly and assembly time.Solve locking plate hole precision simultaneously and the problem of roughness does not reach design requirement.
