Abstract
The present invention relates to a kind of processing technologys in diversion pipe locking plate hole outside nuclear power station axle envelope main pump, numerical control programming processing is carried out using Five-axis NC Machining Center cooperation L-type angle head, using three face sword tool sharpening locking plate holes, process of the invention is processed highly stable when locking plate hole, due to being numerical control processing, to make locking plate hole obtain very high position degree and surface roughness, it solves manual operations and is not able to satisfy required precision, and numerically-controlled machine tool can not carry out the problem of outer diversion pipe locking plate hole machined, and the production capacity and economic benefit that greatly improve enterprise are with processing efficiency.
Description
Technical field：The present invention relates to a kind of processing technologys in diversion pipe locking plate hole outside nuclear power station axle envelope main pump.
Background technique：The outer diversion pipe of nuclear power station axle envelope main pump is one of the 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 diversion pipe is the technology of this workpiece
Problem.The country processes this component beyond example, and the processing method that external colleague uses is assisted using electric hand drill cooperation tooling,
Defect is artificial mode bring unstable quality, and machining accuracy and roughness are all extremely difficult to design requirement,
It needing in later period assembling process, according to locking plate hole the case where, one-to-one reality matched locking plate, the basic demand of workpiece interchangeability is not achieved,
And manual processing low efficiency, adverse effect also is brought to the efficiency of assembly.
Summary of the invention：It is high, high in machining efficiency and can guarantee object of the present invention is to disclose a kind of high reliablity, processing quality
The processing technology in the outer diversion pipe locking plate hole of nuclear power station axle envelope main pump of the outer diversion pipe 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 diversion pipe locking plate hole of nuclear power station axle envelope main pump, is added using five axis
Work center cooperates L-type angle head, has in conjunction with three face angle of throats, carries out numerical control programming processing, and the above method includes the following steps：
It 1) will be on (3) workbench in machining center fixed after outer diversion pipe (1) centering；
2) by L-type angle head (4) installation in machining center (3), three face angle of throats tool (5) is mounted on angle head (4)
On；
3) by drawing size requirement numerical programming processing program, using lathe cutter track analog functuion to cutter track track into
Row simplation verification；
4) according to the material property of outer diversion pipe, Tool in Cutting linear velocity and feed engagement are determined, according to formula S=V/
D/ π, wherein S indicate cutter revolving speed, V indicate cutter linear velocity, D indicate cutter diameter) and F=S × Z × f, F expression cutter into
To speed, S indicates that cutter revolving speed, Z indicate that tool blade number, f indicate cutter feed engagement, calculate cutter revolving 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, workpiece rotation to next locking plate hole site；5) according to step
1) other uniformly distributed locking plate holes are processed to the processing step of step 4).
The invention uses numerical control processing technology, has in conjunction with L-type angle head in three face angle of throats, and substitution colleague uses
Manual processing mode, not only increase processing efficiency so that process time shortens 80% or more, and ensure that processing
The consistency and precision of effect and the requirement of roughness, improve the quality of product, avoid each as caused by manual operations
Locking plate hole is inconsistent, needs to carry out one-to-one adjustment to locking plate according to locking plate hole in assembling process, reduces assembly time, especially
It is in nuclear power station maintenance, this versatile locking plate hole shortens the maintenance that service personnel has radiation in maintenance process
Disassembly and assembly time.Solve the problems, such as that design requirement is not achieved in locking plate hole precision and roughness simultaneously.

Specific embodiment：
A kind of processing technology in the outer diversion pipe locking plate hole of nuclear power station axle envelope main pump, cooperates L-type angle using Five-axis NC Machining Center
Head is spent, is had in conjunction with three face angle of throats as shown in Figure 5, numerical control programming processing is carried out, the above method includes the following steps：
1) it will be fixed on 3 workbench of machining center as shown in Figure 3 after outer 1 centering of diversion pipe as shown in Figure 1；
2) as shown in figure 4, by the installation of L-type angle head 4 in machining center 3, three face angle of throats tool 5 is mounted on angle head 4
On；
3) by drawing size requirement numerical programming processing program, using lathe cutter track analog functuion to cutter track track into
Row simplation verification；
4) according to the material property of outer diversion pipe, Tool in Cutting linear velocity and feed engagement are determined, according to formula S=V/
D/ π, wherein S indicate cutter revolving speed, V indicate cutter linear velocity, D indicate cutter diameter) and F=S × Z × f, F expression cutter into
To speed, S indicates that cutter revolving speed, Z indicate that tool blade number, f indicate cutter feed engagement, calculate cutter revolving speed and feeding
Speed is processed using the numerical control program for verifying errorless, as shown in Fig. 2, processing left side locking plate half bore 2 first, is then processed
Right side locking plate half bore 2, cutter is exited from hole, and angle head returns to workpiece centre, workpiece rotation to next locking plate hole site；5)
Other uniformly distributed locking plate holes are processed according to the processing step of step 1) to step 4).
